Description

Crop root stubble remover

Technical Field

The utility model relates to a crop root stubble remover belongs to crop machinery technical field.

Background

Under the background of increasingly serious environmental pollution and energy crisis, crop straws are widely developed and utilized as a biomass energy source, but the residual stubble resources are not reasonably disposed. The stubbles are used as a renewable biomass energy source and can be removed for resource utilization. Meanwhile, the stubbles of some crops are difficult to completely rot or can become the infection source of viruses when being left in the field, and the crops need to be pulled out during harvesting in order not to influence the cultivation of the crops in the next year.

With the continuous improvement of the technical level of crop production in China, the mechanical technology of crushing and returning the root stubble to the field is applied to corn, wheat, cotton, soybean, sorghum and the like, and the root stubble is directly crushed and returned to the field. However, for the mountainous and hilly areas in southwest, the straw stubbles are mainly planed manually, so that the labor intensity is high, and the working efficiency is low. Therefore, the design and development of the small, simple and portable stubble pulling device suitable for mountainous and hilly areas have very important significance in reducing the labor intensity of farmers, liberating the productivity, improving the planting conditions of crops in the next year and the like.

In order to solve the problems, the crop stubble remover comprises a push rod and a stubble removing rod sleeved on the push rod, the inside of the stubble removing rod is of a hollow structure, the upper end of the stubble removing rod is provided with a handle, the lower end of the stubble removing rod is fixedly provided with a spiral claw, the upper end of the push rod extends to the outer side of the upper end of the stubble removing rod, a push rod handle is fixed at the upper end of the push rod, a spring is sleeved on the push rod at the upper part and is pressed between the push rod handle and the handle, the lower end of the push rod extends to the outlet of the lower end of the stubble pulling rod, a stubble pulling supporting sleeve is also sleeved on the outer side of the stubble pulling rod, the upper end of the stubble pulling supporting sleeve is provided with an external thread, a control handle in threaded connection with the external thread is sleeved on the outer side of the stubble pulling supporting sleeve, and the control handle is fixedly connected with the handle through a handle connecting plate, the lower end of the stubble pulling supporting sleeve is provided with a supporting cylinder which is covered at the lower end of the stubble pulling rod, and the spiral claw extends to the lower part of the supporting cylinder.

In the stubble remover, a boss is welded and fixed at the other end of the push rod;

in the stubble remover, the spiral grabbing device comprises a plurality of grabbing rods which are arranged along the circumferential direction of the stubble pulling rod at equal intervals and are in a spiral shape, and the front ends of the grabbing rods are in a thin pointed shape;

in the stubble remover, the inner side of the stubble removing support sleeve is provided with a linear bearing, and the stubble removing support sleeve is sleeved with the stubble removing rod through the linear bearing.

The use method of the crop stubble remover comprises the following steps:

when the stubble pulling operation is carried out, the spiral claw is aligned to the stubble, the handle is pressed downwards by two hands to enable the spiral claw to cut into the bottom of the stubble, the stubble pulling rod is rotated to enable the stubble to be loosened, then the handle is lifted by two hands to pull out the stubble, and finally the push rod is pushed downwards to enable the stubble to fall off from the spiral claw under the action force of the lug boss, so that the crop stubble pulling is completed; if the root system is developed or the soil is hard, the stubble is pulled out difficultly by lifting the handle, the control handle is pulled to rotate the control handle to drive the stubble pulling support sleeve to move downwards, the control handle is continuously pulled after the support sleeve contacts the soil, the spiral claw and the stubble can be pulled out of the soil, and the effect of saving labor is achieved.

Compared with the prior art, the utility model is suitable for a pull out work of the root stubble of various soil property condition and various crops, its work is laborsaving, and it is higher to pull out stubble operating efficiency, and the device simple structure, and it is convenient to make, low cost, portable and use, especially pull out the stubble operation to crops in mountain hilly area, and use value is very big, suitable popularization.
