    Rotary for tractor
    The present invention relates to a rotary rotary for a tractor, and more particularly, a rotary having a forward / reverse rotation gearbox that reverses / reverses the rotational direction of a tilling blade which draws power from a power generating device such as a tractor to perform work. The present invention relates to a rotary for a tractor that allows a rotary operation and a flattening operation to be performed in combination.
    Recently, due to the development of services, manufacturing-oriented secondary and tertiary industries, the development and dissemination of agricultural work machines has been steadily carried out to reduce the shortage of agricultural workers belonging to the primary industry and the excessive labor intensity. The development of a tractor that can perform various types of work by replacing only a work machine, and the development and distribution of a work machine for a tractor are rapidly progressing.
    As mentioned above, the increase in the spread of tractors may lead to a variety of agricultural work and diversification of agricultural products due to the extraction of a part of the tractor power to drive various work machines with the extracted power.
    For example, in order to carry out a rotary operation, which is one of agricultural operations, a worker combines a rotary to the power take-off shaft (PTO) of a tractor, and then, in order to perform excavation work or flat work after the worker ends the rotary work. Remove the rotary work machine attached to the tractor and carry out the desired work by attaching a tractor excavator or work tool suitable for flat work.
    As such, an agricultural work machine, such as a rotary machine, which performs a predetermined work by the rotational force obtained from the power take-off shaft of a tractor, tills the soil while rotating the tilling blade in a counterclockwise direction (defined as the forward rotation direction). In addition to the work while performing a forward rotation, the soil leveling work that is necessary for orchards, etc. may be performed.
    However, when the soil leveling operation is performed while rotating the tilling blade of the rotary forward, the flattened surface is uneven or the soil leveled by the tilling blade is transferred to the place where the leveling work has already been completed. There is a problem that goes bad.
    Due to this problem, it is more efficient to carry out the soil leveling operation by rotating the tilling blade in the reverse rotation direction than the forward rotation, but the rotation direction of the power extracted from the tractor is fixed in a certain direction, and the power received from the tractor Since there is no means for converting the rotational direction of the rotary in the rotary flat has a problem to buy a separate working machine or use a flat rotary working efficiency is extremely poor planar work.
    Therefore, the present invention has been made in view of such a conventional problem, and an object of the present invention is to be able to change the rotational direction of the tractor rotary to meet the operation purpose.
    Other objects of the present invention will become more apparent from the detailed description of the invention.

The driving bevel gear locking projections 324 may be arranged in a circular manner so as to have a 120 ° interval to each other.
    In the present invention, three driving bevel gear locking projections 324c are preferably formed at 120 ° intervals around the through hole 324a, but three or more driving bevel gear locking projections 324c are formed at the same interval and at the same angle. It is okay.
    In this way, the clutch 350 is inserted into the power input shaft 340 into which the driving bevel gear 324 is inserted.
    The clutch 350 has a bushing shape having an inner diameter that is inserted into the power input shaft 340. A ring-shaped groove 352 having a predetermined depth is formed on the outer circumferential surface of the clutch 350.
    Clutch locking protrusions 354 are formed at both ends of the clutch 350 formed as described above so as to be engaged with the driving bevel gear locking protrusion 342c.
    At this time, the power transmitted from the power take-off shaft of the tractor to the power input shaft 340 must be transmitted to the clutch 350 without loss, and the power is transmitted to the driving bevel gear 324 by the clutch 350.
    Therefore, in order for the clutch 350 to receive power from the power input shaft 340 without losing power, there should be no slip between the clutch 350 and the power input shaft 340. To this end, a sprocket (342) is formed in the center portion of the power input shaft (340) to protrude slightly than the power input shaft (340), and the sprocket-shaped gear train (290) is coupled to the sprocket (342) at the inner diameter of the clutch (350). 356 is formed.
    While the clutch 350 is gear-coupled to the sprocket 342, another driving bevel gear 322 is inserted into the power input shaft 340 so as to face each other with the clutch 350 interposed therebetween. At this time, the two driving bevel gears 324 and 322 facing each other have the same shape, and the teeth of the driving bevel gears 324 and 322 face each other.
    After the two driving bevel gears 324 and 322 are all inserted into the power input shaft 340, the driving bevel gears 324 and 322 may be inserted into the opening 301 of the gearbox housing 310 to prevent the driving bevel gears from escaping to the outside. In order to support the other end of the 340, the second gearbox housing cover 316, which also has the double stepped portions 316a and 316b, is screwed.
    At this time, the outer ring of the ball bearings 317 and 318 is forcibly fitted to the two stepped portions 316a and 316b, respectively, and the inner ring of the ball bearings 317 and 318 is the outer peripheral surface of the bushing 322a of the driving bevel gears 322 and 324 and the power input shaft ( 340 is fitted to the outer peripheral surface.
    Meanwhile, the driven bevel gear 330 is inserted into the other opening 302 perpendicular to the power input shaft 340 of the gearbox housing 310, and the teeth of the driven bevel gear 330 face each other. And interdigitated with the teeth of the two driving bevel gears (324,322).
    At this time, the rotation direction of the driven bevel gear 330 is determined by the rotation of the driving bevel gears 322 and 324.
    The bushing 334 protrudes to have a predetermined height in the through hole 332 having a predetermined diameter formed at the center of rotation of the driven bevel gear 330 geared to the driving bevel gears 322 and 324 as described above. On the outer circumferential surface of the inner ring of the ball bearing 336 is forcibly fitted.

    The other end of the power output shaft 370 protruding from the steel pipe 380 is provided with a spur gear 375 to be coupled to the aforementioned power transmission gearbox 240.
    Meanwhile, the clutch 350 needs to be moved between the driving bevel gears 324 and 322 so that the direction of power by the clutch 350 can be changed, and thus the clutch driving device 360 for driving the clutch 350 is required.
    The clutch drive 360 cuts a predetermined area of the gearbox housing 310 corresponding to the ring-shaped groove 352 of the clutch 350 and then is inserted into the cut portion.
    The clutch drive 360 is simply inserted into a sleeve 364 formed in the fourth gearbox housing cover 362 and the fourth gearbox housing cover 362 for sealing the cut-out portion of the gearbox housing 310. The clutch rod 366, the rotation lever 368 for rotating the clutch rod 366 by a predetermined moment, is coupled to the surface of the clutch rod 366 in the shape of "a" shaped by the rotation direction of the rotation lever 368 It consists of a rotating clutch drive member 369. At this time, the clutch drive member 369 is inserted into the ring recess 352 of the clutch 350.
    Thus, simply inserting the clutch drive member 369 into the ring-shaped groove 352 of the clutch 350 is the clutch 350 regardless of whether the clutch 350 is rotated at a predetermined number of revolutions or the rotation of the clutch 350 is stopped. In order to be able to move to either of the two driving bevel gears (322,324).
    However, when the clutch 350 is coupled to one of the driving bevel gears 322 and 324 and rotates, the clutch 350 may be frequently removed from the driving bevel gears 322 and 324. Therefore, the driving bevel gears 322 and 324 may frequently occur. When the clutch 350 is coupled to any one of the power supplies, the power input shaft 340 is 360 degrees along the power input shaft 340 to prevent the clutch 350 from being arbitrarily detached from any one of the driving bevel gears 322 and 324. A "Ｖ" shaped clutch release prevention groove 346 is formed and the clutch 350 is provided with a clutch release prevention device 358.
    The clutch release preventing device 358 is configured to engage the clutch 350 at a predetermined position on the outer circumferential surface of the clutch 350 in a state where the clutch engaging protrusion 354 of the clutch 350 and the driving bevel gear engaging protrusion 324 are engaged with each other. The through hole 358a through which the inlet is penetrated and the inlet is tapped, and through the inlet of the tapped through hole 358a, the inserted steel ball 358b and steel ball 358b are pressed into the through hole 358a. Spring 358c having a predetermined modulus of elasticity inserted through), spring 358c and steel ball 358b is composed of a screw 358c coupled to the tapping portion in order to prevent the departure from the outside.
    At this time, the sprocket 342 formed in the power input shaft 340 corresponding to the steel ball 358b is formed with a "Ｖ" shaped departure prevention groove 346, as described above, the steel ball 358b is coupled to the departure prevention groove 358b. And optionally prevents the clutch 350 from being removed from the designated positions of the drive bevel gears 322 and 324.
    At this time, even if the clutch 350 is coupled to any of the driving bevel gears 322 and 324, the release preventing groove 346 is formed by the clutch 350 and 2 to prevent the clutch 350 from being arbitrarily removed from the driving bevel gears 322 and 324. No matter which of the two driving bevel gears 322, 324 is to be combined with the steel ball 358b should be formed of two.
    Referring to Figure 5 or 6 attached to the operation of the tractor rotary according to the present invention having such a configuration as follows, a tractor equipped with a forward / reverse gearbox described in detail as an embodiment It will be described to plan the uneven soil immediately after the rotary operation with the rotary.
    First, the operator rotates the clutch drive 360 to perform a rotary operation, thereby moving the clutch 350 toward any one driving bevel gear 322.
    Thereafter, the clutch engaging protrusion 354 of the clutch 350 is engaged with the driving bevel gear locking protrusion 322c of the corresponding driving bevel gear 322 and power is transmitted from the power input shaft 340 to the clutch 350. At the same time, the power transmitted to the clutch 350 is transmitted to the driving bevel gear 322 to rotate the driving bevel gear 322 in a predetermined direction.
    At this time, the power transmitted to the driving bevel gear 322 is directly transmitted to the driven bevel gear 330 geared to the driving bevel gear 322, the power transmitted to the driven bevel gear 330 is the power output shaft 370. After being transmitted to the power transmission gearbox 240 through, the power transmitted to the power transmission gearbox 240 is transmitted to the work tool 100 so that the work tool 100 and the tilling blade 10 is rotated. Perform a roundabout operation.
    In this case, the direction in which the work tool 100 rotates by the rotation of the driving bevel gear 322 will be defined as a forward rotation direction.
    When the rotary operation is completed by the work mechanism 100 rotating in the forward rotation direction as described above, the operator rotates the rotation lever 368 of the clutch drive device 360 in the opposite direction to perform the flattening operation with the rotary.
    At this time, as the rotation lever 368 rotates, the clutch 350 is removed from the currently coupled driving bevel gear 322 and moves to the opposite driving bevel gear 324 along the sprocket 342 formed on the power input shaft 340. It is engaged with the driving bevel gear 324.
    As a result, the power transmitted to the clutch 350 through the power input shaft 340 is transmitted to the opposite driving bevel gear 324 so that the driving bevel gear 324 is rotated and driven bevel geared to the driving bevel gear 324 at the same time. Gear 330 also rotates.
    At this time, the rotation direction of the driven bevel gear 330 is rotated in the opposite direction, that is, the reverse direction when the clutch 350 and the other driving bevel gear 322 is engaged.
    As the driven bevel gear 330 rotates in the reverse direction, while the rotation direction of the power output shaft 370 also rotates in the reverse direction, the work tool 100 and the tilling blade 10 rotate in the reverse direction to perform the flattening operation.
