Novel deep ploughing machine capable of being automatically cleaned and using method thereof

Abstract

The invention provides a novel deep ploughing machine capable of being automatically cleaned and a using method thereof. The novel deep ploughing machine capable of being automatically cleaned comprises a car body, a plough tool, soil collecting and adding devices and a control system, wherein the car body is provided with a cleaning water tank; the lower part of the car body and the inner part ofthe soil collecting and adding device are provided with movable spraying heads; the plough tool mainly comprises a connection fork rack, a front plough head and a rear plough head; the connection fork rack is hinged with the car body, the end part is provided with the front plough head and the rear plough head, and the inner part is provided with a first screw conveyor rod; two groups of plough knives are arranged on the front plough head and the rear plough head respectively in an inserting mode; each soil collecting and adding device mainly comprises a soil conveying device and a soil loosening cavity; one end of the soil conveying device is connected with the front plough head and the back plough head, and the other end is lifted upward to the soil loosening cavity; the soil looseningcavity is internally provided with a soil loosening rotating column and the bottom part is provided with a soil return conveying belt; and the soil collecting and adding device is connected with a fertilizer adding box and a pesticide adding box. The functions are practical and efficient, and various problems brought by the traditional shallow ploughing can be improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a novel deep tillage machine capable of automatic cleaning and a use method thereof. Background technique [0002] The growth of crops needs to be rooted in the mellow soil layer, and under the mellow soil layer is the bottom layer of the plow, which is the maximum depth of cultivation. The traditional animal plow plow has uneven plow bottom, the plow depth is generally only about 12cm, and it cannot turn the soil well. At present, rotary tillage is the main method in many areas, but the rotary tiller is affected by the power transmission mechanism of the tractor and the rotary tiller. Restricted by factors such as the diameter of the cultivating knife, the operating depth of rotary tillage does not exceed 15cm. In Yunnan, Guizhou, Sichuan and other regions, the cultivating depth of the micro-tiller that is developing rapidly is only about 10cm. If things go on ...

AI Technical Summary

Problems solved by technology

The traditional animal plow plow has uneven plow bottom, the plow depth is generally only about 12cm, and it cannot turn the soil well. At present, rotary tillage is the main method in many areas, but the rotary tiller is affected by the power transmission mechanism of the tractor and the rotary tiller. Restricted by factors such as the diameter of the tiller blade, the operating depth of rotary tillage does not exceed 15cm. In Yunnan, Guizhou, Sichuan and other regions, the tillage depth of the micro-tiller that is developing rapidly is only about 10cm.

If things go on like this, the thickness of the mellow soil layer decreases, and the thickness of the plow bottom layer increases, which brings many problems to the cultivated land: first, the plowing depth is too shallow, only about 10cm on the surface, and the air permeability and water permeability of the plow bottom layer are very poor. The development of the root system after entering the bottom of the plow is seriously affected, making the root system of the plant underdeveloped, thereby affecting the growth of the plant; secondly, shallow plowing cannot kill the pests and eggs in the deep soil, and the pests will cause damage to the crops after they mature. Thirdly, the fertilization of the land generally only reaches the surface of the soil layer, and there are problems of shallow fertilization depth and uneven fertilizer amount; finally, due to the extensive use of chemical fertilizers, the soil compaction is more serious, and the traditional farming methods cannot well compact the soil. break up the soil

The utility model deepens the depth of the cultivated land through the plowing method of the two-stage plowing knife, and puts the fertilizer into the soil during the plowing process, which has the effect of fertilizing while plowing the land; but the plowing method of the utility model cannot ensure the uniformity of soil fertilization , the fertilization opening on the secondary tiller blade is also easily blocked by soil, and it has no function of pesticide application and insecticide. It cannot break up the compacted soil while cultivating the land, and its practicality is not enough.
