Deep cultivator and method of use thereof

Abstract

The invention provides a new type of deep tiller and its use method, including a car body, a plow, a soil collection and feeding device and a control system; the plow mainly includes a connecting fork, a front plow share and a rear plow share; The connecting fork frame is hinged with the car body, and the front plow share and the rear plow share are arranged at the end, and the screw conveying rod I is arranged inside; two sets of coulters are respectively inserted into the front plow share and the rear plow share; the soil The collecting and feeding device mainly includes a soil conveying device, a loose soil chamber and a soil return conveyor belt; one end of the soil conveying device is connected to the front plow share and the rear plow share, and the other end is lifted upwards to the loose soil chamber; A loose soil rotating column is arranged in the soil cavity; the soil return conveyor belt is arranged under the loose soil rotating column; the soil collecting and feeding device is connected with a fertilizer box and a medicine adding box; the car body, plow and The soil collection and feeding devices are all connected to the control system. The invention has strong practicability and high working efficiency, and can improve various problems caused by traditional shallow tillage.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a deep cultivator 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.

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.
