Description

FIG. 2

The invention relates to agricultural machinery, in particular, embedmenting work tools of extirpation type used on combined machines, combining flat-cut soil tillage with soil application of bulk materials, such as seed or mineral fertilizers, and their mixtures.

The purpose of the invention is to increase reliability in operation and simplify the design.

FIG. 1 shows a vomer, general view from above; in fig. 2 - the same, rear view; in fig. 3 - kinematic coulter; in fig. 4 - guiding element made in the form of a block of pitched trays; in fig. 5 - the same, in the form of a ramp; Fig 6 - the same, in the form of a part of the cone.

The opener includes a plate post 1 (Fig. 1), in the back of which a tubular tube 2 is attached. A tubular tube 2 on the lower end has two outlet sleeves 3 (Fig. 2). An extipator is attached to the front of the rack. A paw 4 is attached to the lower part of the paw, at its rear edge, on both sides of a flat spring 5 and b (FIG. 3), made in the form of plates mounted parallel to the axis of the paw. To the lower ends of the flat springs, there are attached guide elements in the form of pitched trays 7, mounted obliquely from the middle to the edges at an angle to the horizon of 3 °. The inner ends of the trays are located under the diverting sleeves 3. The pitched trays 7 have different lengths, their outer edges 8 are located along the width of the grip of the paw with the same mm pitch (Fig. 4).

The trays are interconnected by an additional transverse flexible thread in the form of a cable 9. In the central part of the flexible thread 10 is made in the form of a cable passing into a hole made between the diverting sleeves. The flexible thread 10 is a kinematic connection between the pitched trays and the oscillating drive drive 11. A flexible thread is connected to the actuator 11 by means of a talper 12, and the specified thread is supplied to the actuator using a block 13 having an axis of rotation 14. The actuator 11 may have a kinematic connection (not shown) with the tractor's PTO or the driving wheel of the unit.

Guiding elements can also have other forms of implementation, for example, in embedding bodies for continuous introduction of bulk materials they are made in the form of a sloped board 15 (Fig. 5) having oblique seeding edge 16. In embedding organs with a small width of grip (up to 45 cm) the guide member should be made as part of a cone 17 (Fig. 6).

Before the operation of the unit, the actuator 11 is adjusted at a predetermined frequency and amplitude of oscillations, then with the aid of a talper 12, a flexible thread is pulled up to

the position at which the reverse springs take the deformed position (deviating from the neutral position). In the process of moving the unit drive 11

It acts through the flexible thread 10 (passing through the block 13, rotating on the axis 14) in the middle of the additional thread 9 and t is not upwards. The ends of the thread 9, moving trays 7, and moreover, due to the fact that the trays 7 are connected by thread 9, they move simultaneously in the vertical and horizontal planes, shifting in this case to the middle of the embedding body. At the same time, the reversal springs 5 and 6 are rejected from their initial position. The trays at the same time make a movement that is very close along its path to the plane-parallel one. The drive pushes the threads and trays to the upper end position (shown in dotted line in Fig. 3), then the drive itself performs a blank (reverse) stroke. During this process, the threads are in the tensioned position under the action of reversing springs 5 and 6. The springs 5 and 6 of the trays 7 tend to occupy a normal (level) position, several

5 are aligned while moving the trays 7 and the yarns 9 and 10 downwards. However, the springs 5, 6 are not straightened out evenly, as initially, when adjusted, the threads 9 and 10 are pulled with the help of a talper 12. The threads 9 and 10 and the trays 7 of the spring 5 and 6 move to the lowest position ( Fig. 3 shows this position in full lines). By connecting the trays 7 with an additional flexible thread 9, all the reversing springs are simultaneously acting on the thread 10. Simultaneously

5, the drive completes the idle and begins to act on the thread by moving it up. The thread and the trays are also moved upwards, the springs being further deformed. Thus, the work cycle is repeated again, and so on. The angle of inclination of the trays is kept almost constant.

When the extirpator paw moves in the soil, the tuki enters the tubular tuku5 guide 2, under the action of gravitational forces, passes the specified tukonaphonchik, is divided into two approximately equal flows and is directed into the sleeves 3. On the sleeves, the 3 tukas also move under the action of gravitational forces, and then through

0, the lower holes of the sleeves 3 are sown in guide elements made in the form of trays. The fertilizers that have entered the trays due to the oscillatory movement of the latter and the inclination of the trays are moving in a continuous flow to the edges 8, leaving the lot of fertilizer sown with ribbons.

A layer of soil coming from the paw covers the ribbon of fertilizer on top.

The peculiarity of the opener, equipped with guide elements made in the form of a pitched board 15 (Fig. 5), having a slanting sowing edge 16, is that the material coming from the board 15 is sown in a sub-valve space with a solid screen.

During the operation of the opener, having a guide element in the form of a part of a cone (Fig. 6), the material entering through the conductor 3, under the action of gravitational forces, reaches a part of the cone 17, and then along its working surface is directed into the sub-valve space.

In the construction of the vomer, pivotal joints are absent in the sublap space. This increases the reliability of the device.
