RU2510165C1 - Device for dressing of row spacing of tilled crops - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention refers to agricultural engineering industry, and namely to working elements for tilled crop production. A device includes a working element in the form of a spring. Spring axis is bent through 180° along arc of circle and inclined at angle α to horizontal plane to the side opposite to translation movement of a unit. The spring is fixed on the frame with possibility of free rotation about its axis. One spring end is connected to a drive providing its rotation in the direction opposite to translational movement of the unit in the zone of contact with soil surface. At operation of the unit, the ratio of $$\frac{V_o}{V_e}>1$$

is maintained, where V_o - peripheral speed of spring turns in the soil contact zone; V_e - translational movement speed of the unit.

EFFECT: improved design.

Description

The invention 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) [1], consisting of a coupling, support wheels, a frame and several rows of working sections fixed from it from disk working bodies of different diameters. 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 [2], in which the working bodies are made in the form of a rotary hoe, disc dumpers with protective aprons, lancet paws, razor paws and spring harrows. 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 problem to which the invention is directed, is to increase the efficiency and quality of inter-row tillage when cultivating row crops with minimal energy consumption.

EFFECT: increased degree of crumbling of the surface soil layer, destruction of the soil crust and removal of weeds.

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

figure 1 - General view of the 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 (Fig. 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 to the side, opposite to the translational movement of the unit, mounted on the frame 2 with the possibility of free rotation around its axis. Moreover, 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

$$\frac{V_o}{V_e}>\mathrm{one,}$$

where V ₀ - 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

$$\frac{V_o}{V_e}>\mathrm{one,}$$

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 circumferential speed of the spring coils V _o in the contact zone with the soil surface will be greater than the translational velocity of the aggregate V _{e, the} soil coils and weeds trapped in the spring coils are captured by the spring coils.

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 immersed to a depth of h 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.
