Abstract

A device for processing row-row crops, containing a frame, a drive and a working body, made in the form of a spring, the axis of which is bent 180 ° along an arc of a circle and is located in a plane inclined at an angle α to the horizontal to the side opposite to the translational movement of the unit, mounted on the frame with the possibility of free rotation around its axis, while one end of the working body is connected to the drive, providing its rotation in the direction opposite to the translational movement of the unit in the contact zone with surface soil, and maintained sootnosheniegde V- circumferential speed of coils in the zone of contact with the ground; V- translational movement of the unit speed.

Description

The utility model relates to the working bodies of agricultural machines and is used in the cultivation of row crops.

Known universal cultivator for inter-row tillage, containing a disk working body (cultivator) (Patent 86749 of the Russian Federation, publ. 09/10/2009), consisting of a coupling, support wheels, a frame and several rows of working sections from disk working bodies of different diameters fixed to it. The disadvantage of this cultivator is the crushing of lumps of soil of only a certain size, corresponding to the distance between the discs, and the inability to remove weeds.

A device is also known for cultivating soil between rows when cultivating row crops and other crops (Patent 2148302 of the Russian Federation, publ. 10.05.2000), in which the working bodies are made in the form of a rotary hoe, disk dumpers with protective aprons, lancet paws, razor paws and spring harrow. The disadvantages of this design are the complexity of its manufacture and high energy consumption associated with the movement of the unit on the surface of the field during operation.

The task to which the proposed utility model is directed is to increase the efficiency and quality of inter-row tillage when cultivating row crops with minimal energy consumption.

The technical result is an increase in the degree of crumbling of the surface soil layer, the destruction of the soil crust and the removal of weeds.

A device for processing row-row crops - presented on:

Figure 1 - General view of a device for processing row-row crops (a - front view; b - side view);

Figure 2 - Scheme of the process when grinding soil lumps;

Figure 3 - The principle of operation of the device for processing rows of row crops when removing weeds.

The technical result is achieved by the fact that the proposed device (figure 1) contains a frame, a drive and a working body made in the form of a spring, the axis of the spring is bent 180 ° along an arc of a circle and is located in a plane inclined at an angle α to the horizontal opposite to the translational the movement of the unit, mounted on the frame 2 with the possibility of free rotation around its axis. In this case, one end of the spring element is connected to the actuator 3, providing its rotation in the direction opposite to the translational movement of the unit in the zone of contact with the soil surface, and the ratio is maintained:

,

,

where V _o - the peripheral speed of the coil of the spring in the zone of contact with the soil;

V _e - translational speed of the unit.

The principle of operation of the device is as follows. When the device moves across the field with a translational speed V _e , the working body 1, made in the form of a spring, while in the row-spacing, receives rotation around its axis from the drive 3, while it rotates in the direction opposite to the translational movement of the unit in the zone of contact with the soil surface, moreover, the ratio is maintained:

,

,

where V _o - the peripheral speed of the coil of the spring in the zone of contact with the soil;

V _e - translational speed of the unit.

Due to the fact that the peripheral speed of the spring screws V _o in the contact zone with the soil surface will be greater than the translational speed of the aggregate V _e , soil lumps and weeds are caught by the spring coils falling into the inter-turn space of the spring.

When the rotation of the working body 1, made in the form of a spring, the distance between its turns will decrease from the maximum value to the minimum or zero, in case of contact of the turns. Lumps of soil trapped in the inter-turn space (Fig. 2) are first trapped (zone A), then displaced and partially destroyed - zone B, and completely destroyed - zone B. In addition to the destruction of soil lumps, the working body is immersed to a depth h, not exceeding the height of the spring profile will also destroy the soil crust. The principle of operation of the device for processing row-row crops for removal of weeds is shown in figure 3. Weeds trapped in the inter-turn space are trapped by coils of a spring in zone D, then moved and removed from the soil in zone D, and then dumped onto the soil surface in zone E.

Thus, when the device passes through the row-row of row crops, weeds are destroyed, the soil crust is destroyed and soil lumps are crumbled, thereby increasing the efficiency and quality of row-row cultivation of row crops.
