Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery and can be used for tillage in growing crops. The unit is proposed which working bodies are made in the form of a knife with a cavity where an igniter is placed, actuated by a measuring rim periodically closing the electrical circuit contacts. The drive of the measuring rim is actuated from the support-drive wheel of the device, and to supply the explosive the device is provided with a batch dosing pump.

EFFECT: reduced power consumption of soil loosening by reducing the tractional resistance of tillage outfit, and as a result, reducing the cost of tillage.

Description

The present invention relates to the field of agricultural engineering and can be used for tillage in the cultivation of crops.

A known unit for the mechanical processing of soil by deforming and loosening it, including a frame with support drive wheels, on which a container for solid mineral fertilizers and working bodies made in the form of a knife are installed (Khalansky V.M., Gorbachev I.V. “Agricultural machines. ”- M .: KolosS, 2005, pp. 200-202).

A disadvantage of the known unit is the high energy intensity of the soil treatment process and the large metal intensity of the unit.

The objective of the invention is to reduce the energy intensity of the tillage process by reducing the traction resistance of the tillage unit and, as a result, reduce the cost of tillage.

The task is achieved due to the fact that loosening the soil is carried out by exploding gaseous, liquid or solid explosives (BB) at the depth of the soil tillage, supplying explosives to the cavities of the working bodies of the soil tillage unit, made in the form of a knife with a cavity in which the igniter is placed a device driven by a measuring wheel periodically closing the contacts of an electric circuit. The measuring wheel is driven from the drive wheel of the unit, and the device is equipped with a batch metering pump for explosives.

The drawing schematically shows the unit for tillage by loosening.

A tank 2 is installed on the frame 1, a metering pump 3, the purpose of which is to periodically supply the explosive in portions into the cavity 4 of the knife 5. In this case, the cavity 4 is equipped with an ignition device 6, driven by a measuring wheel 7, which acts with its stops uniformly located around the entire circumference, to the contact 8 of the electric power unit 9. The measuring wheel 7 is kinematically connected with the support-drive wheel 10 of the unit and due to this it is driven. Knife 5 has adjusting holes 11 to move it vertically.

The unit operates as follows.

When the unit moves, the knife 5 is deepened to a predetermined depth of soil cultivation, set by moving the knife 5 vertically using the adjustment holes 11. A metering pump 3 driven by a tractor power take-off shaft (not shown in the diagram) periodically delivers a dose of explosive into cavity 4, which explodes with the ignition device 6, driven by a measuring wheel 7, which is in interaction with the supporting-drive wheel 10 of the unit.

Due to the explosion, the soil loosens, and the knife together with the unit receives a force in the form of a slight push in the direction of the working movement of the unit, which reduces the traction load on the tractor, reducing the traction resistance of the soil cultivating unit and thereby reducing the cost of cultivating the soil.
