Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase operational reliability. The moon shaper includes a rod 1 mounted on a leading 3 crank and a crank 4, made in the form of a compensating elastic element containing a sleeve 5. A sleeve 5 is installed in the radial bore of the trunnion 6. In the sleeve there is a cover 8 and a cable 10 with a spring 12 which is connected an axis 14 hinged on the rod 1. A compression spring 16 is placed outside the sleeve 8 between the cover 8 and the trunnion 6. When the rod 1 penetrates into the soil larger than a given value, or when it comes into contact with stones and other objects, it compensates for Thu sprung movement of the sleeve 5 with respect to the trunnion 6 provides a change in the length of the crank 4, which eliminates the possibility of breakage of components lunkoobrazovatel. 1 hp f-ly, 2 ill.

Description

FIELD OF THE INVENTION The invention relates to agricultural machine building, in particular, to longing formers of planting machines.

The purpose of the invention is to increase operational reliability.

FIG. 1 shows the proposed bore shaper landing machine in the cutter, rear view; in fig. 2 is a diagram of the movement of the links of the borehole with a depth greater than the optimum.

In the case when the place of implementation of the rod 1 on the soil surface is a mound or the aggregate wheel falls into the hole, i.e. there is an excess of the optimal depth of the hole, there is an increase in the time spent by the rod 1 in the soil, and hence the path traveled by the rod in the soil together with the tractor. The upper end of the rod 1 in this case moves in the direction of decreasing the length of the compensating

The moon shaper includes a rod 1, of an elastic element, acting through an axis 14, a driving shaft 2, a leading crank 3, a cryo-damper 15, a cover 8 on a sleeve 5, which

moves relative to the trunnion 6, while compressing the spring 16. The described

wax 4, made in the form of a compensating elastic element. The latter contains a sleeve 5 installed with the possibility of linear movement in the radiator from the breakage. After the pinhole 6, which is connected to the supporting rod 1 from the soil, emerges, the spring 16 returns 7, which is rigidly fixed to position the sleeve 5 to its original position,

(not shown).

Thus, the proposed device provides a reduction relative to the initial length of the compensating elastic

The movement of the sleeve 5 protects the lungs. A sleeve 8 is installed in the sleeve 5, equipped with an opening 9 in which a cable 10 is placed, to the end of which a stop 11 is fixed in the sleeve 5, and a compression spring 12 is installed between the stop 11 and the cover 8.

The free end of the cable 10 is fastened with the help of a friction clamp formed by the bolt 13 and the wall of the hole made in the axis 14 pivotally connected to the rod 1.

A damper 15 is installed between the cover 8 and the axis 14 on the cable 10. Covering the sleeve 5, between the trunks b and the cover 8 there is an elastic element in the form of a spring 16 in the stressed state. At the hinge joint of the crank 3 and the rod 1 there is disc brake 17.

The moon former of the landing machine works as follows.

element with significant deepening of the rod, which ensures the protection of the latter from damage.

Claims (2)

1. The moon former of the planting machine, containing a rod hinged on two cranks, the lower of which is driven, and the upper is made as a compensating elastic element including a sleeve with a lid connected to the support through a pin and a spring enclosing the associated spring a cable, characterized in that, in order to increase the torque from the tractor PTO through 35 operational reliability, the spindle reducer is transmitted to the drive shaft 2, then through the driving crank 3, It is placed on rod 1, which penetrates the soil and forms a well. With the free course of the moon former (above the soil), the springs 12 and 16 have a maximum length, and the damper 15 abuts against the cover 8 of the sleeve 5. A radial hole is not provided, and the sleeve of the compensating elastic element is installed in the latter with the possibility of linear mixing, and an elastic element is installed between the cover of the sleeve and the trunnion. 2. The moon shaper of claim 1, wherein the resilient element is designed as a compression spring. In the case when the place of implementation of the rod 1 on the soil surface is a mound or the aggregate wheel falls into the hole, i.e. there is an excess of the optimal depth of the hole, there is an increase in the time spent by the rod 1 in the soil, and hence the path traveled by the rod in the soil together with the tractor. The upper end of the rod 1 in this case moves in the direction of decreasing the length of the compensating  elastic element, acting through the axis 14, the damper 15, the cover 8 on the sleeve 5, which  breaker creator. After the release of the rod 1 from the soil, the spring 16, the return of the sleeve 5 protects the lungs. Thus, the proposed device provides a reduction relative to the initial length of the compensating elastic element with significant deepening of the rod, which ensures the protection of the latter from damage. Invention Formula 1. The moon former of the planting machine, containing a rod hinged on two cranks, the lower of which is driven, and the upper is made as a compensating elastic element including a sleeve with a lid connected to the support through a pin and a spring enclosing the associated spring A rod is a cable, characterized in that, in order to increase the radial opening, the sleeve and the sleeve of the compensating elastic element are installed in the latter with the possibility of linear mixing, and between the cover of the sleeves Pin and pin mounted elastic element. 2.
