SU1713458A1 - Working tool of cultivator - Google Patents

Description

The invention relates to agricultural machinery and can be used in tillage tools for the cultivation of annual crops in the early stages of their cultivation.

The purpose of the invention is to improve the quality of tillage and thinning of annual crops.

Figure 1 shows the working body of the cultivator, side view; figure 2 - cultivator, front view; on fig.Z - a finger with a knife; FIG. 4 is a knife; in Fig. & - longitudinal profile of the plate.

The working body of the cultivator contains axis 1, fixed on support 2, on axis 1 with the possibility of free rotation mounted sg / pin 3 with radial fingers 4. On each finger 4 is rigidly fixed, iozh 5 protruding beyond its free end.

Knife 5 has airborne pets plastics 6, Cutting Kpohwta 7 nazab is located at an acute angle, for example 72-76 ° (the best option is 74, to the plane, and which the fingers 4 of the working body are located, and at an acute angle of 6-10 ° (optimal 8 °) to the axis t., On which the mouth of the oval is hub 3. Edge 7 corresponds to the large base 8 of the trapezium formed by the plate 6.

Each plate is 6 "angled curved. Its curvature is reversed on the side of rotation of the working organ. In the section of the finger unit, the radius of the plate arc is 3, S times the length of this section. All plates b are located on one side of the plane in which units 4 are located. that the side 9 of the trapezoid plate is located in this plane.

On the finger 4, the visor 10.8 is welded. There is an elongated groove 11. The CQOT grooves 12 are in the plate 6. The plate 6 is connected to the visor 10 by means of the bolted joint 13. By moving the bolted joint 13 in the grooves 11 w 12, the plate can be adjusted relative to the plane , 8 of which are located the fingers 4 of the working body. In another embodiment, the visor 10 is not welded to the finger 4. but has a landing nest which is held on the cone-shaped finger by friction.

To the axis 1 through the sleeve 14 can be attached an additional working body 15 located mirror symmetrically with respect to the main.

In the process of work, the knives 5 of the working body loosened the soil and, for example, cotton. Crashing into the soil with a pointed end, the knife loosened the soil crust, partially grab, lift the soil and loosen it, i.e. hacking is done. When the agraphone is changed, the position of the plates is adjusted relative to the plane in which the fingers are located.
