Automatic feeding and neat cutting type straw cutting and grinding device

Abstract

The invention discloses an automatic feeding and neat cutting type straw cutting and grinding device, and relates to the technical field of agricultural machinery. The automatic feeding and neat cutting type straw cutting and grinding device comprises a shell; a cutting circular groove is formed in the middle of the interior of the shell; a storage groove is formed in one side of the cutting circular groove; the bottom of the inner wall of the storage groove is obliquely designed; and a feeding hopper is mounted at the position, located above the storage tank, of the top of the shell. The automatic feeding and neat cutting type straw cutting and grinding device solves the problems that in an existing straw cutting and smashing device, cutting is uneven, cut straw is different in size, timeof decomposition for providing nutrients after returning is different, absorption of crops in soil to the nutrients is affected, meanwhile a matched conveying device is needed for continuously conveying the straw to a cutting device, the device is relatively complex in structure and relatively high in cost, the straw returning difficulty is increased, the straw at the bottom of a storage bin is likely to be omitted and difficult to convey to the cutting device, and the straw cutting and returning efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a straw chopping device that automatically feeds and cuts neatly. Background technique [0002] Straw returning is a method of returning corn stalks to the field to apply straw (corn stalks, sorghum stalks, etc.) that are not suitable for direct feed into the soil directly or piled up and decomposed, which can improve soil properties, accelerate raw soil maturation, and increase soil fertility. , When directly plowing the straw, some nitrogen fertilizer should be applied to promote the straw to decompose in the soil and avoid competition between decomposing bacteria and crops for nitrogen. The straw should be cut and crushed before returning to the field to help the straw decompose quickly. However, the existing straw cutting and crushing device cuts unevenly, and the size of the chopped straw after cutting is different, and the time required to decompose and provi...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a straw chopping device that automatically feeds and cuts neatly, which can solve the problem that the existing straw cutting and crushing device cuts unevenly, and the chopped straws after cutting are of different sizes and decompose after returning to the field. The time required to provide nutrients is also different, which affects the absorption of nutrients by crops in the soil. At the same time, a supporting conveying device is required to continuously transport straw to the cutting device. The structure of the device is more complicated and the cost is higher, which increases the difficulty of returning straw to the field. Straw at the bottom of the warehouse is easy to miss and difficult to transport to the cutting device, which reduces the efficiency of straw cutting and returning to the field
