专利说明:
I FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to pneumatic sowing apparatus; exact seeding. Pneumatic sowing machines are known, including a seed chamber; a housing; a seed disk mounted on the axis of rotation; a tedder installed in the seed chamber; and a device for removing excess seeds in the form of a selection plate with cutouts in the form of saw teeth SP. Such a shape of the selection plate allows seeds to be set in motion only in the radial direction, i.e. either to the center of the disk or to the periphery 5, which reduces the quality of removal of excess seeds from sucking holes. The closest in technical essence to the present invention is a pneumatic sowing device, including a housing, seed and vacuum chambers, between which a sowing disk with circumferentially suction holes, a spindle installed in the seed chamber and a device for removing seeds, mounted on the axis of rotation, having consecutive teeth 5 alternating below and above the circle on which the suction holes are made, the upper teeth being displaced relative to the lower ones, The gap between the circumference and the lower teeth decreases in the direction of rotation of the sowing disc, and the mechanism for adjusting the distance from the upper and lower teeth to this circumference, turns on the 1st lever C 21. A disadvantage of the known device is the limited number of tooth effects on the seeds (only two pushes on each side) s the absence of a free edge or the edges of the teeth on the side of the touch of the teeth. have a rounded shape that contributes not to the rotation of the grains and their sliding, All this reduces the uniformity of sowing of seeds by reducing the quality of removal of excess seeds. The purpose of the invention is to improve seeding uniformities by improving removal of weakened seeds. 90382 The goal is achieved by the fact that in a pneumatic sowing apparatus there is an exact sowing. The teeth are set on two plates mounted on a disk 5 along their edges closer to the center of the disk and directed radially, and the edges of the plates are located around a circle on which suction holes are made. at that, one ends of the plates are hinged to the body by means of an axis perpendicular to the disk. In addition, the lever for adjusting the distance is pivotally mounted on the housing and is equipped with an eccentric valve II and J located on either side of its axis of attachment and interacting :: c Q cutouts made on the other ends of the plates. The agitator is installed in the seed chamber by means of its axis of rotation, which is perpendicular to 5 axis of rotation of the disk and kinematically connected with the latter. In addition, 5 the kinematic link is made in the form of a gear set on the axis of rotation of the tedder and circumferentially formed in the area of the axis of rotation of the disk of the cutouts that engage with the gear teeth. The kinematic connection is made in the form of a roller set on the axis of rotation of a tedder made of a material with a higher coefficient of friction, which is pressed against the disk. Fig. II shows the proposed apparatus, a section j in Fig. 2 shows a device for removing excess seeds, 5 of a disassembled state; on fig.Z the same, front view; Fig. 4, then iice, side view, S, Fig. 5 is the lower part of the apparatus proposed, where the tedder is installed, a partial SJ view of FIG OO - the proposed apparatus, section A-A on, a passage along the axis of the tedder. The apparatus includes a bunker 1 for s, ° m H5, installed above a vyiseyupp-n disk 2j located above ploughshare 3, P1 is designed to be punctured, the grooves in the soil are furrowed, the whole unit is mounted on a conventional chassis (not shown), The double disc 2 has a perforated suction hole 4 and is enclosed in a housing 5, the internal cavity of which is divided into two adjacent compartments, the disc being mounted on an axis 6 driven in rotation by gears (not shown), and the cardan 7 provides connection to the wheel of the crop or any other body providing the speed of rotation proportional to the speed of movement of the crop. One of the compartments communicates with the outlet to the bottom of the hopper 1 and serves as a seed chamber 8 for the seeds. The other compartment is connected to a suction device (not shown) by means of a flexible hose 9 and is a vacuum chamber 10. In the upper part of the case a device 11 is attached to remove excess seeds, which has an elongated shape and is pressed to the seed disc. The device 11 is hinged on it The housing 5 with the axis 12, pressed into the hole 13, is made in the housing in the immediate vicinity of the peripheral surface of the disk 2 perpendicular to it, and consists of two plates 14 and 15, the edges of which are located closer to the center of the disk. respectively, the radially directed teeth 16 and 17. The plate 14 has an elongated shape, and its end directed against the rotation of the disk is made in the form of a fork with a notch 18, which includes the cam 19 of the lever 20, which is part of the distance adjustment mechanism from the upper and the lower teeth up to the circle on which the suction holes 4 are located. The lever 20 is fixed to the axis 21, which is forbidden into the hole 22 filled in the housing close to the edge of the disk. The other end of the plate has a mounting hole 23 through which the axis 12 passes The edge 24 of the plate 14, located closer to the center of the sowing disc, is curved along a curve corresponding to the trajectory described by the holes 4 of the disc 2. The tooth 16, made on the edge 24 of the plate 14 ,. are located at an equal distance from each other, and their ends 2-5 are slightly bevelled relative to the circle on which the suction holes are located. The second plate 15, mounted next to the plate 14, has a similar shape. At one end there is also a fork with a notch 26, where the cam 27 of the lever 20 enters, and at the other end there is a hole 28 through which the axis of attachment 12 passes. The edge 29 is also curved along a curve corresponding to the trajectory described by the holes 4. Tooth 17, which are made along the edge 29, are equally spaced from each other and fit into the spaces between the teeth of the 16 gpasti 14, when the two plates are folded together. The middle part of the plate 15 is stamped and offset from both ends of this plate in such a way that when both plates are folded together, they touch only their ends, while their middle parts are parallel to each other with the teeth 16 and 17. The cams 19 and 27 of the lever 20 are located eccentrically on either side with respect to the hole 30, through which the axis 21 passes, are in the form of a circular disk and are mounted adjacent to each other. After assembly, the plate 14 is pressed against the disk 2 in such a way that the suction holes 4 pass in front of the beveled ends 25 of the teeth 16, located on one side of the trajectory described by the holes 4, for example from the outside, as is the case in the present embodiment. In order for the teeth 17 of the plate 15 to also be pressed against the disk 2 and that their ends are also located near the trajectory described by the suction holes 4 of the disk 2, but from the side opposite the one where the tooth 16 of the plate 14 is located, the tooth 17 is hook-shapedly bent inwards so that that their ends 31 are located in the same plane as the tooth 16 of the plate 14, i.e. in the plane of the disk 12. The plates 14 and 15 of the device 11 must be installed so that during operation the paths described by the suction holes 4 of the disk 2 pass between two rows of teeth 16 and 17 alternating on the other side of this path, Since both plates are hinged on the axis 12, mounted in the hole 13 perpendicular to the plane of the disk 2, adjusting the angle between these two plates allows you to simultaneously zoom in or out the teeth 16 and 17 relative to the path described by the suction holes 4, D The check is carried out with the help of a lever 20, turning on its axis 21 n acting on plates 14 and 15 by means of two cams 19 and 27, entering respectively cuts 18 and 26. Turning the lever allows the plates to be pulled apart or folded or narrowing the passage in the form of an angle between the opposite rows of teeth 16 and 17. This passage has a funnel shape and tapers in the direction of rotation of the disk 2 so that the selection of excess seeds becomes more accurate as the suction holes 4 with the seeds advance between otivolezhaschimi alternating rows of teeth. As shown in FIG. 5 and 6, the proposed apparatus also includes, located in the lower part of the seed chamber 8 of the housing 5, agitating 32, equipped with mixing blades 33 and mounted on the end of axis 34, at the other end of which gear 35 is installed, Axis 34 is rotatably parallel to the plane. A sowing disc 2 in a smooth liner 36 mounted in the wall of the cus 5 of the apparatus. The dp of rotation of the tedder 32 on the sowing disk 2 is made up of a circular array of 37, evenly distributed around the axis 6 of the disk. The gear tooth 35, reinforced with a key (not shown) on the axis of the tedder 34, is engaged with said notches 37 in such a way that the rotation of the disk 2 causes the tedders 32 to simultaneously rotate, which, mounted at the level of the suction holes 4, nudge seeds in the direction of the holes 4. It should be noted that the location of the agitator around an axis parallel to the plane of the disc makes it possible to Bring the agitator into baking with the pomopd of this disc itself and makes it possible to dispense with any additional s gears. The gear 35j and also the notches 37 in the disk 2 can be replaced with a roller made of materials with a higher friction coefficient, for example, of rubber, reinforced with a key (not shown) on the axle 34 of the spudger 32 and pressed to the disk 2 with temp; in order to ensure the transfer of rotational movement through friction. Appa;) at works as follows. When the suction holes 4 of the disk 2 pass between the seven-chamber chamber 8 and the adjacent vacuum chamber 10, each of them sucks one or several seeds from the chamber and transfers them to the upper part of the apparatus, where accumulations of seeds formed on the suction holes 4 the disk 2 is alternately pushed out from one side to the ends 25 of the teeth 16, which push these clusters towards the center of the disk; forced them to rotate clockwise, and on the other side to the ends 31 of the opposite teeth 17, which, conversely, push these clusters to the outer edge of the disk, caused them to rotate counterclockwise. Under the influence of these shocks and turns, then in one direction, then in the other direction gradually. the seeds, which appear in an unstable equilibrium position, are lost, and at the exit of the device 11 in the hole there is only one semes, the location of which in the center of the hole allowed him to transfer the repeated jolts of the device 11 and not fall out of the hole. During operation, the angle between the two plates 14 and 15 remains constant, and the lever 20 stops; In the case of changing the type or size of the CCI-IHH, you can change the angle of the Mesgi.y plates by turning the lever 20 in a circle around its axis 21. To improve grip Seed with suction holes 4 of the seed disc 2 in the seed chamber 8 agitates the seeds and pushes them toward the disc 2 using the agitator 32 5 rotating around an axis 34 parallel to the flat surface of the disc. The proposed apparatus can be performed with some vadoizmeyenky mi. So, for example, two plates 14 and 15 can be used for sampling, which is not on the same co.;., Hz, evom row of suction holes and on two concentric rows, and kgs ™ Yes, the plate can serve its RID, and the adjustment of the device for the selection of excess can be carried out with one lever. In this case, in order to avoid unnecessary seeds falling into the internal row of suction holes and sucking them without the possibility of subsequent Removing the last tooth in the direction of rotation of the disk should be performed on a plate that interacts with the internal row of holes. The use of the invention will improve the uniformity of sowing seeds by improving the removal of excess seeds from the suction holes. fig 70 ff fS /five //
