Description

The present invention relates to seeding. coil type devices with simultaneous

by separate sowing of dissimilar materials (for example, seeds and fertilizers, grasses and grasses) and with the use of double

 seed boxers.

In FIG. 1 shows the external appearance of the apparatus; FIG. 2 is a vertical section of it, FIG. 3 is a vertical longitudinal section of the lower part of the apparatus; FIG. 4-b - details of the controller.

The main part of the proposed apparatus for sowing seeds of various breads is a fluted coil 2 (Fig. 1, 2), located under the seed box

driven by the roller 4 from the axis of the traveling wheels of the machine. The coil is covered by a box consisting of two parts, of which the front / bolts 17 are attached to the bottom of the seed box, and the rear one is suspended on the axis 12 rotatably and can be opened by rotation about the axis / S for the purpose of cleaning or inspecting the apparatus. The front part of the box from the top ends with a rectangular box, so-called. receiving chamber with a flange i without a back wall. The inner cavity of the upper chamber of the box is divided

on two channels a and ". a wall G extending in the lower part of the box into rib 1 (Fig. 2), provided with a groove (Fig. 3) for ring 5 (Fig. 2 and 3) having cutouts corresponding to the profile of the coil teeth and separating the coil along into two parts l and g / 2. In the groove of the right wall, there is the same ring, which rotates with the coil and overlaps the coil cavities with its teeth in order to cause the grain to fall out of the box on its right side. To prevent the outflow of grain from the left working part of the coil, the latter is provided with a sealing ring S-, overlapped in part by its shoulder (not shown in the drawing)

3 of the usual type, filled with a radial plate o, on the shaft

4 and intended to block free access of grain to the chamber during axial movement of the coil, in order to install the latter onto one or another seeding density.

Depending on the size of the seeds, the size of the free gap between the coils of the coils and the internal surface of the box in the upper part of the box, two controllers are designed for the right and left chamber. Each regulator consists of a plate 5 located above the coil, for moving which in the vertical direction serves as a valve, b, passing through the openings of the front wall to the outside, where it is supported by an anchor bar O attached to the flange jf. The rollers are driven in rotation from two, levers 70, one of them is fixed on the axis of the left chamber adjuster, and the other on the axis of the right cam adjuster. The first, at its lower end, is connected movably with a pull 16, which passes in front of the apparatus and has fingers 16 (Fig. 1-2), which are located at a distance equal to the distance between the centers of the two axes of the adjuster (like chambers). The fingers are connected alternately with all the levers 14, which are tightly fixed on the axes of the controls of the same chambers. As a result of such a device, the movement of the lever 70 is transmitted through all small levers, which rotate all axes at the same angle with the first one, which causes the raising or lowering of the knobs to be performed in exactly the same way. To rotate the controls of the right-hand chambers there is a ha of 75 identical devices with the one described above. To secure the levers in a certain position, there are arcs 77 on which they are fixed by means of the thumbs 13, which are on the threaded rods of the said levers. Meadow;. and; -: Eat numeric tags that correspond to certain polo-; een; -: m controllers, for their turn .ib that correspond to certain types of seeds for sowing. On the back wall of box 22 there is a plate 35 (Fig. 1) with the designation of the types of grain corresponding to the digital signs on the arches 77. When the roller rotates, the pinion U mounted on its end moves with the aid of a rack on the plate; /, and with it, the intermediate plate is about the holes put on the holes o and the pins o °. A turn regulator damper cr is kept from falling out of the guides with the spike of the plate into the slot V. Spring 5 allows for the possibility of independent, raising the regulator damper to a certain height, which can reduce the crushing of grain and the possibility of breakdowns if solid objects enter the apparatus. Between the extreme and middle ribs of the rear part of the box 7 (Fig. 2) is placed along the wide spring 7 (Fig. 2), which with their lateral edges come close to the above-mentioned edges. The springs at the bottom and at the top are fastened with screws 21 (Fig. 2); at the bottom tightly, and at the top, so that they have a free course, equipped with an elongated slot. In the middle part of the spring, they have a cylindrical curvature, which closely fits the coil and the cylindrical surface of the spool; therefore, the grain from the receiving chamber does not wake up, no matter how small it is. The lower part 6 of the box passes into two grain outlet funnels S and S-, separated from each other by a partition 8 and corresponding to the two working parts of the coil. Such a device of the apparatus of double action can be important in those cases when. there is a need for a close mutual arrangement of the coulters or the direction of two separate jets of grain into one coulter, as, for example, with different mixtures. In the latter case, the seeding density for the right part of the apparatus operating at a constant length of the coil is set by changing the gear ratio OTt .. of the axles of the traveling wheels to the roller 4 (changing gears), and for the left-moving the coil with the roller in the axial direction. To direct the components of the mixture to the right and left parts of the apparatus, the seed box is divided by a vertical longitudinal wall 23 (respectively, for two types

The warp) (Fig. 2) is placed on two uneven parts with notches 55 (Fig. 1) located above the openings 31. in the bottom of the box, which take the grain to the apparatus. On both sides of the wall against the cut-out there is a frame (Fig. 1-2) with the corresponding cutouts 27 at the bottom, the edges of which, when the frame is laid, coincide with the edges of the cut-out wall. The frame has side grooves in which the caps 2c are held, moving up and down along the frame. The caps have an eyelet 26 with rings .9 which hold the middle wall hooks in a raised position. When the wall 23 is in the lowered position, the caps overlap the holes of the bottom of the crate (this is done when two types of grain are sown at the same time) so that only the right, j or left chambers of the devices can enter from one cavity of the grain box. depending on the installation of caps. The seed box is emptied from sowing by tilting the rear part P (Fig. 2) of the box.,.

The installation for sowing two types of grain is simultaneously performed as follows: the middle wall of the crate (Fig. 2) must be lowered, and the caps in placed in the proper order. The flaps of the right chambers are pushed in, and the regulators are installed on the corresponding types of grain, using the plate 35 (Fig. 1). After such a preliminary preparation, they pour in both parts of the soup; tea, so that the grain intended for sowing B a large quantity by leg is poured into a large part of the container, and the other into a smaller cavity. Since the left camera operates continuously without changing the working part of the roller, the installation is performed by changing the speed of rotation of the roller 4 (changing gear wheels). After the installation has been achieved, they start to install on the second grain, but already by moving the sowing shaft from the lever () (Fig. 1), use the sign 40 (Fig. T) for this;

By this, the flaps of the right chambers are advanced and the left flaps are pushed. After the installation work, the plant is ready to be sown in the field. The rotation of the sowing roller 4 is caused by the rotation of the crop sprocket by transferring gears. Disengagement of the seed shaft should be done by decoupling the gears sitting one on the roller 4 and the other on the running wheel.

When sowing one grain, the installation is carried out almost exclusively by the second method, i.e., by moving the roller 4 along its axis along a raised middle wall or caps.

With the aid of the apparatus proposed, it is possible to sow the mixture in such an order (regular sowing) that one grain can be sown in one or two or three. etc., plots of sowing another type of grain, and it is also possible to work with the most diverse types of seeds; Starting from seed to smaller clover, and inclusively to the largest pea, with the same coil.

The subject of the patent.
