    Disperser {distributor}
    The present invention relates to a spreader for dispersing particles and powders, such as, for example, snow powders.
    12 and 13, there is a spreader 100 that is towed to the truck T conventionally. The spreader 100 has a trailer 101 and a funnel hopper 102. Hopper 102 is loaded on trailer 101. The hopper 102 contains, for example, a snow powder. An opening 102a is formed under the hopper 102. The snow melt powder is scattered downward from the opening 102a. The trailer 101 is connected to the rear part of the truck T. As shown in FIG.
    The trailer 101 has an axle 104a and wheels 104 supported at both ends thereof. The differential bevel gear device 103 is fitted to the axle 104a. The drive shaft 103a extends perpendicularly to the axle 104a and toward the hopper 102. One end of the drive shaft 103a has a bevel gear meshed with the differential bevel gear device 103. The spreading plate 105 is fixed to the drive shaft 103a. The spreading plate 105 is disposed below the opening 102a so as to face the opening 102a. The snow melting powder falls from the opening 102a onto the spreading plate 105 by its own weight. When the truck T moves, the rotation of the wheel 104 is transmitted to the spreading plate 105 through the axle 104a, the differential bevel gear device 103, and the drive shaft 103a. As a result, the spreading plate 105 rotates. Then, the snow melting powder on the spreading plate 105 is scattered around the spreader 100 by centrifugal force.
    However, the dispersion plate 105 is directly fixed to the drive shaft 103a which rotates in conjunction with the differential bevel gear device 103. That is, the spreading plate 105 always rotates while the truck T runs. This is inappropriate when the truck T moves without dispersing while towing the spreader 100. For example, when the truck T travels at high speed during the movement to the scattering destination or the return home after the scattering, the scattering plate 105 also rotates at high speed. Since the scattering plate 105 has an unavoidable dimension error in manufacturing, vibration occurs during its rotation. Therefore, in particular, when the spreading plate 105 rotates at high speed, an excessive load due to vibration acts on the fixing portion between the spreading plate 105 and the drive shaft 103a, and the fixing portion tends to be damaged.
    In order to solve this problem, it is also conceivable to put a clutch mechanism on the power transmission path from the wheel 104 to the spread plate 105. However, the clutch mechanism is complicated in structure. Therefore, neglecting the management may cause a malfunction caused by infiltration of snow powder.
    SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a spreader capable of selecting rotation and stopping of the scattering plate at the time of running the vehicle with a simple configuration.

    11 spreader, 12 guide rail, 13 body frame, 16 hopper, 16a opening, 18 wheel, 19 axle, 20 differential, 21 drive shaft, 25 spreader, T truck .
    A spreader according to a first embodiment of the present invention will be described with reference to the drawings.
    (First embodiment)
    As shown in FIG. 1, the truck T has a carrier N. As shown in FIG. The rack N is provided with the backboard G. The spreader 11 of 1st Embodiment is attached to the rear gate G. As shown in FIG.
    As shown in FIGS. 2-4, the spreader 11 has a pair of guide rails 12. As shown in FIG. The pair of guide rails 12 are fixed to the outer surface of the rear gate G of the truck T so as to extend in the vertical direction. Each guide rail 12 has a groove along its longitudinal direction. The pair of guide rails 12 are arranged in parallel with each other such that the grooves face each other and at predetermined intervals.
    The main body frame 13 includes a main frame 14 and a hopper frame 15 fixed to the main frame 14. The main body frame 13 is detachable with respect to the guide rail 12. The hopper frame 15 extends along the guide rail 12. Two guide rollers 15a are mounted on both outer surfaces of the hopper frame 15, respectively. Each guide roller 15a is rotatable along the side of the groove of the guide rail 12. Thereby, the main body frame 13 can be raised and lowered along the guide rail 12 via the guide roller 15a.
    And when separating the main body frame 13 from the guide rail 12, the lower guide roller 15a guides the main body frame 13 along the guide rail 12 by manpower or a crane apparatus, for example. Raise until it escapes from the top of the groove of the rail 12. On the contrary, when attaching the main body frame 13 to the guide rail 12, the lower guide roller 15a is lowered from the upper end of the groove of the guide rail 12 along this groove.
    The hopper 16 for accommodating the snow melting powder is fixed to the hopper frame 15. As shown in FIG. 5 and FIG. 6, an opening 16a is formed under the hopper 16. The hopper 16 has a tapered lower portion which is collected toward the opening 16a. On the outer bottom face of the hopper 16, the cover body 17 for closing the opening 16a is arrange | positioned. The lid 17 has a lever 17a at one end thereof, and is attached to the hopper 16 so as to be rotatable around a substantially vertical axis at the other end. When the lever 17a is operated, the lid 17 rotates in the horizontal plane. Thereby, the opening angle of the opening 16a is adjusted.
    As shown in FIG. 5, outside the main frame 14, a pair of wheels 18 are rotatably supported by the axle 19. A well-known differential device 20 having a bevel gear is fitted on the axle 19. The difference in rotation between the two wheels 18 is absorbed by the differential device 20. The drive shaft 21 extends from the differential apparatus 20 in the direction orthogonal to the axle 19. The axle 19, the differential device 20 and the drive shaft 21 transmit the rotation of the wheel 18 to the drive shaft 21.
    The stand 14a is mounted to the lower part of the main frame 14. The stand 14a is comprised so that it may not contact the ground in the state shown in FIG. 1 in which the spreader 11 was attached to the truck T. FIG. In the state where the spreader 11 is not attached to the truck T, that is, the main frame 13 is separated from the guide rail 12, and the wheel 18 is grounded, The main body frame 13 can be moved by. When the spreader 11 is tilted slightly toward the stand 14a, the stand 14a is grounded. As a result, the main body frame 13 is not inverted and is supported by both the wheels 18 and the stand 14a.
    As shown in FIGS. 2 and 3, the handles 22 are mounted on both sides of the mainframe 14. The handle 22 is rotatable between an unused position indicated by a solid line in FIG. 3 and a used position indicated by a two-dot chain line. When the spreader 11 itself is moved by the attraction force, the handle 22 is disposed at the use position. The worker can grip the handle 22 and move the body frame 13.
    As shown in FIG. 4, the jack sheet Ga is protrudingly provided in the rear gate G. As shown in FIG. The jack 23 is attached to the position which opposes the jack seat Ga of the hopper frame 15. As shown in FIG. As shown in FIG. 4 and FIG. 7, when the wheel 19 is grounded and the jack 23 is contracted, the jack 23 does not contact the jack seat Ga. That is, the spreader 11 is disposed at the ground position shown in Figs. As shown in FIG. 8 and FIG. 9, when the jack 23 is extended, the jack 23 abuts against the jack sheet Ga and pushes up the main body frame 13 with the jack sheet Ga as a starting point. Then, as shown in FIG. 8 and FIG. 9, the main body frame 13 is raised along the guide rail 12, and the wheel 18 raises upwards from the ground. In other words, the spreader 11 is disposed in a non-grounded position.
    Each guide rail 12 is equipped with a lock pin 24 via a chain, for example. Each guide rail 12 is formed with a hole 12a for locking. As shown in FIG. 7, in the state where the spreader 11 is arrange | positioned at the ground position, the locking hole 12a is located above the upper guide roller 15a. On the other hand, as shown in FIG. 8, in the state where the spreader 11 is arrange | positioned at the non-grounding position, the locking hole 12a is located below the upper guide roller 15a. If the lock pin 24 is inserted into the lock hole 12a in this state, the guide roller 15a abuts against the lock pin 24, so that the body frame 13 cannot move downward from the non-grounded position. Therefore, even if the support of the jack 23 is released by mistake in this state, the wheel 18 is not grounded.
    As shown in FIG. 5 and FIG. 6, the spreading plate 25 is disposed between the main frame 14 and the hopper 16 to face the opening 16a. The spreading plate 25 has a disk-shaped plate 25a and a plurality of fins 25b. In the upper surface of the plate 25a, the fin 25b extends radially in the radial direction near the center of the plate 25a. The drive shaft 21 is fixed to the center of the spreading plate 25. As a result, when the wheel 18 rotates, the rotational force is transmitted to the spread plate 25 through the axle 19, the differential device 20, and the drive shaft 21. The shielding plate 26 is installed upright between the spreading plate 25 and the truck T on the upper surface of the main frame 14.
    Next, an example of the spreading operation of the snow melting powder using the spreader 11 of the first embodiment will be described.
    The truck T is also used for applications other than the spreading of the snow powder. Therefore, the body frame 13 is separated from the guide rail 12 and the main body frame 13 is stored in a warehouse or the like except for the spraying work of the snow melting powder. At this time, with the support of the wheels 18 and the stand 14a, the main body frame 13 can be stored without the main body frame 13 standing on the wall surface of the warehouse or lying on its side.
    On the other hand, when spreading snow melt powder, the main body frame 13 must be first shipped and it must be attached to the truck T. Here, when moving the main body frame 13 near the truck T, first, the main body frame 13 is inclined in order to separate the stand 14a from the ground. Then, the main body frame 13 is grounded only by the wheels 18 and thus is movable. When the handle 22 is placed in the use position when the main body frame 13 is moved, the movement becomes easy.
    The main body frame 13 moved near the truck T is attached to the guide rail 12 as described above. After mounting, the jack 23 is extended to raise the main frame 13 along the guide rails 12 and to be placed in the non-grounded position. In this state, the lock pin 24 is inserted into the lock hole 12a to lock the main frame 13 in the non-grounded position. In the state which closed the opening 16a by the cover body 17, snow melt powder is thrown into the hopper 16. As shown in FIG. The snow melt powder for replenishment may be loaded in the carrier N of the truck T.
    In the above state, the truck T is moved to the distribution destination. In this movement, although the truck T may travel at high speed, since the wheel 18 is arrange | positioned at an ungrounded position, it does not rotate. Therefore, the spreading plate 25 does not rotate.
    When arriving at the distribution destination, the lock pin 24 is released and the lock of the main frame 13 is released. Thereafter, the jack 23 is contracted and the main body frame 13 is lowered by its own weight and placed at the ground position. Next, the lid 17 is rotated to open the opening 16a. The snow melt powder is then supplied from the hopper 16 onto the spreader plate 25 by the action of gravity.
    When the truck T runs in this state, the wheel 18 in the ground position rotates. This rotation is transmitted to the spread plate 25 via the axle 19, differential 20 and drive shaft 21. Then, since the spreading plate 25 is rotated, the snow melting powder supplied on the spreading plate 25 is scattered around by the action of the centrifugal force. The snow melting powder scattered toward the truck T is bounced back by the shielding plate 26. Therefore, the snow melt powder is scattered in a fan shape to the rear of the traveling direction of the truck T.
    After completion of the spreading operation, the lever 17a is operated to close the opening 16a. The main body frame 13 is placed in an ungrounded position by extending the jack 23. Next, the lock pin 24 is inserted into the lock hole 12a, and the main frame 13 is locked at the non-grounded position. In this way, the wheel 18 is arrange | positioned at an ungrounded position. Therefore, the wheel 18 does not rotate even when the truck T travels at high speed in the return destination at the distribution destination. Therefore, the spreading plate 25 does not rotate.
    The spreader 11 of the first embodiment has the following effects.
    When driving the truck T, when the spreading plate 25 is to be rotated, the main body frame 13 is disposed at a ground position. It may be placed in a non-grounded position. Therefore, it is possible to arbitrarily select the rotation / stop of the spreading plate 25 when the truck T travels without employing a complicated mechanism such as a clutch mechanism. In addition, since a complicated mechanism such as a clutch mechanism is not employed, malfunction of the spreader 11 is unlikely to occur without frequent management, and the reliability of the spreader 11 is improved.
    The hopper 16, the spreading plate 25, the power transmission mechanisms 19 to 21 and the wheels 18 are attached to the main frame 13. The main frame 13 can be attached to or detached from the guide rail 12. Therefore, the truck T can be used for applications other than the spraying work by separating the main body frame 13 from the guide rails 12.
    The shielding plate 26 is arrange | positioned between the spreading plate 25 and the truck T. As shown in FIG. Therefore, the snow melt powder can be prevented from scattering on the truck T side, and waste can be prevented from scattering efficiently.
    (2nd embodiment)
    Next, with reference to FIG. 10 (a) and FIG. 10 (b), the dispersing machine of 2nd Embodiment of this invention is demonstrated centering on difference with 1st Embodiment.
    In 2nd Embodiment, the structure of the cover body 17 is different from 1st Embodiment. In the first embodiment, the lid 17 opens and closes the opening 16a by manual operation. In contrast, in the second embodiment, the lid 32 opens and closes the opening 16a in accordance with the rotational speed of the spreading plate 25.
    In the vicinity of the center of the spreading plate 25, the guide frame 31 is fixed to the upper end of the fin 25b. The guide frame 31 is rectangular. A pair of cover body 32 is arrange | positioned inside the guide frame 31. As shown in FIG. Each lid 32 is slidable along the length of the guide frame 31. The spring 33 is biased toward the center of the guide frame 31 for each cover 32. As a result, as shown in Fig. 10A, the lids 32 abut each other.
    When the truck T travels in a state where the wheels 18 are arranged at the ground position, the spreading plate 25 rotates. When the spread plate 25 rotates, the guide frame 31 also rotates along with the spread plate 25. At this time, a centrifugal force acts on each cover body 32 in a direction in which each cover body 32 deviates from the center of the guide frame 31, that is, a direction in which the opening 16a is opened. This centrifugal force is proportional to the rotational speed of the spreading plate 25. When this centrifugal force becomes larger than the biasing force of the spring 33, each cover body 32 is mutually spaced apart. As a result, the opening 16a is opened. The biasing force of the spring 33 is set such that the lid 32 is spaced apart from each other when the traveling speed of the truck T exceeds a predetermined value (for example, 3 to 5 km / h).
    In a state where the traveling speed of the truck T does not reach a predetermined value, the lids 32 abut each other. When the traveling speed of the truck T exceeds a predetermined value, the centrifugal force acting on each lid 32 exceeds the biasing force of the spring 33. As a result, as shown in FIG. 10 (b), each cover body 32 is separated from the biasing force of the spring 33, the opening 16a is opened, and the snow melting agent is supplied onto the spreading plate 25. do.
    For example, when the driving speed of the truck T becomes lower than or equal to a predetermined value at the time of stopping by the road signal, the rotation speed of the spreading plate 25 is lowered, and the centrifugal force acting on each cover body 32 is applied to the spring 33. It is less than bias force of). Therefore, as shown in FIG. 10 (a), the lid 32 closes the opening 16 a by the biasing force of the spring 33, and the supply of the snow powder onto the spreading plate 25 is stopped. . As a result, in a situation such as a signal atmosphere, there is no problem that the snow melting powder is continuously supplied onto the spreading plate 25 that is not rotating.
    (Third embodiment)
    Next, with reference to FIG. 11, 3rd Embodiment of this invention is described centering on difference with 1st Embodiment.
    In the third embodiment, the spiral screw 35 is disposed near the opening 16a in the hopper 16. The outer diameter of the screw 35 is larger than the inner diameter of the opening 16a and can close the opening 16a. The screw 35 has a shaft 35a, which is fixed coaxially with the drive shaft 21 via the plate 25a. Thus, the screw 35 rotates in accordance with the rotation of the spread plate 25. When the truck T runs while the wheels 18 are in the ground position, the snow melt powder in the hopper 16 is sequentially transferred toward the opening 16a along the spiral of the screw 35 and spreads. It is supplied to the plate 25.
    When the rotation of the spreading plate 25 is stopped, the rotation of the screw 35 is also stopped. Due to the helical complexity of the screw 35 in this state, the snow melting powder in the hopper 16 is hard to move toward the opening 16a, and is hardly supplied onto the spreading plate 25. That is, the opening 16a is substantially closed when the rotation of the screw 35 stops.
    In addition, you may change each said embodiment as follows in the range which does not deviate from the meaning of this invention.
    The hopper 16 is separated from the main body frame 13. In this case, the hopper 16 is mounted on the carrier N of the truck T.
    The operation cable is connected to the cover body 17 so as to be able to operate the opening and closing of the cover body 17 from the cab of the truck T, for example.
    The cover 17 is opened and closed by connecting an actuator to the cover 17 and operating the actuator by remote operation from the cab of the truck T, for example.
    Changing the jack 23 to a structure that is stretched by an electric motor or hydraulic pressure. In this case, the lifting operation of the main body frame 13 is simplified.
    The spreading unit 11 can scatter particles and powders such as seeds, pesticides, and fertilizers, in addition to the snow powder.
    According to the spreader of the present invention, it is possible to arbitrarily select rotation / stop of the scattering plate at the time of traveling of the truck without employing a complicated mechanism such as a clutch mechanism. In addition, since a complicated mechanism such as a clutch mechanism is not employed, malfunction of the spreader is unlikely to occur without frequent management, and the reliability of the spreader is improved.
