Embodiment 1

[0038] A straw returning device, including a shell 1, the shape of the shell 1 is not limited, it can be customized according to actual needs, the shell 1 is provided with a crushing device 3, the purpose of the crushing device 3 is to achieve crushing The function is mainly to crush the straw, mix the crushed straw with the soil evenly, and avoid that most of the crushed straw is still exposed on the soil surface and is easily blown away by the wind. Not only cannot the purpose of returning the straw to the field, but also will cause environmental pollution;

[0039] The middle position of the pulverizing device 3 is provided with an automatic pressing device 4. The purpose of the automatic pressing device 4 provided by the present invention is to insert and press the crushed straw into the depth of the soil, so that it can be mixed evenly with the soil, thereby improving the fertilizer efficiency of the soil. can be more uniform;

[0040] The outer right side of the housing...

Embodiment 2

[0054] On the basis of Embodiment 1, a carding device 5 is provided on the left side of the housing 1, and the connecting ring 52 of the carding device 5 is sleeved on the connecting rod 501, and the connecting rod 501 is arranged at the left end of the housing 1 , the carding device 5 includes a connecting frame 53, and the right end of the connecting frame 53 is provided with a connecting ring 52;

[0055] The left end of the connecting frame 53 is lowered evenly to be provided with a plurality of rake teeth 51, which are arranged side by side at a certain interval to facilitate the raking operation of the soil; after the crushed straw is mixed with the soil, the surface will Uneven, some places are too high, some places are too low, need to go through manual leveling treatment, increase the manpower burden, therefore, the present invention can pass through the cooperation of the connecting frame 53 and the rake teeth 51 by setting the carding device 5 The crushed soil is ra...

Abstract

The invention relates to the technical field of agricultural machinery, and discloses a straw returning device which comprises a shell, a smashing device is arranged in the shell, an automatic inserting and pressing device is arranged in the middle of the smashing device, and a rolling device is arranged on the right side of the outer portion of the shell. The automatic inserting and pressing device is used for inserting and pressing smashed straw into the deep position of soil, the smashed straw can be conveniently and evenly mixed with the soil, and therefore the fertilizer efficiency of the soil can be more uniform.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a straw returning device. Background technique [0002] Straw is the main waste produced when crops are harvested. In the past, straw was usually used as fuel or animal feed. With the popularization of fossil fuels and industrial feed, the function of straw as fuel and livestock feed has basically been lost; many existing technologies It has also been proposed to use straw for industrial application, such as straw power generation, etc., but on the one hand, the agricultural crops are concentrated and mature in an area, and the straw is light and heavy, and the harvesting season is within a very short few days. It is difficult to collect a huge amount of straw within a few days of the harvest season. Even if a large amount of straw is successfully collected, its storage is still a problem. Since the straw is loose and light-weight material, the stacking volume is t...
