Description

Technical Field

[0001] This utility model relates to the field of straw returning machine technology, specifically a self-propelled agricultural machinery straw crushing and returning machine. Background Technology

[0002] Directly returning straw to the field can lead to poor soil aeration, the breeding of pests and diseases, and is detrimental to the growth of subsequent crops. Therefore, a self-propelled straw crushing and returning machine is needed to crush the straw on-site, allowing it to decompose quickly and be integrated into the soil, transforming it into available nutrients. A self-propelled straw crushing and returning machine is an agricultural machine used after crop harvest to crush, spread, and return residual straw in the field.

[0003] The self-propelled straw crushing and returning machine proposed in the existing technology needs to crush and return the straw in the field in one operation. However, since the crushing blades of some models are fixedly connected to the machine body, it is impossible to adjust the blade spacing and speed according to the type of straw (such as corn stalks and wheat stalks) and the field humidity. This makes it easy for the machine to over-crush different types of straw, resulting in low efficiency in returning straw to the field. Not only is it easy for the crushed straw to be scattered by the wind, but it also leads to uneven straw returning quality, affecting subsequent crop planting and making it inconvenient to use.

[0004] Therefore, we proposed a self-propelled agricultural machinery straw crushing and returning machine to the field to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a self-propelled agricultural machinery straw crushing and returning machine to the field, so as to solve the problems mentioned in the background technology, where the straw crushing and returning machine is inefficient for workers, the crushed straw is easily scattered by the wind, and the quality of straw returning to the field is uneven, which affects the subsequent crop planting and is inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-propelled agricultural machinery straw crushing and returning machine, comprising a vehicle body, an installation shell installed at the front end of the vehicle body, a transmission component fixedly installed inside the installation shell, a compaction slider movably installed on one side of the transmission component, and a crushing roller movably installed on the same side of the transmission component, wherein the compaction slider is closer to the vehicle body than the crushing roller, and a scraper is rotatably installed on the outer side of the crushing roller, and the scraper is movably installed on one side of the transmission component.

[0007] Preferably, an arc groove is provided below the mounting housing, and a crushing roller is installed in the arc groove. A sliding groove is also provided below the mounting housing, and a compaction slider is slidably installed inside the sliding groove. The sliding groove is closer to the vehicle body than the arc groove. A feed inlet is provided on one side of the mounting housing, and the feed inlet is connected to the arc groove.

[0008] Preferably, the transmission assembly includes a motor and a first transmission disc fixedly installed at the output end of the motor. A transmission belt is movably installed on the outer periphery of the first transmission disc, and a second transmission disc is movably installed inside the other end of the transmission belt. A connecting shaft is fixedly installed on the inner side of the middle of the second transmission disc, and a crushing roller is fixedly installed on the other end of the connecting shaft.

[0009] Preferably, a sliding column is fixedly installed on the inner side of the first transmission disk, and the sliding column is slidably installed on both sides of the compaction slider, and a transmission rod is rotatably installed on the outer periphery of the sliding column.

[0010] Preferably, a compaction cone is fixedly installed below the compaction slider, and sliding rails are fixedly installed on both sides of the compaction slider. Each sliding rail has a sliding hole inside, and a sliding column is slidably installed inside the sliding hole.

[0011] Preferably, connecting rods are fixedly installed on both sides below the scraper, and a transmission rod is movably installed on the outer side of the connecting ring via a rotating shaft. Connecting rings are fixedly installed below each connecting rod, and the connecting rings are rotatably installed on the outer periphery of the connecting shaft via a rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. When it is necessary to crush straw in the field, start the motor to make the connecting shaft drive the crushing roller to rotate, crush the straw, and then spread it on the ground. At the same time, the first transmission disc drives the sliding column to rotate, causing the compaction cone to move up and down, pressing the crushed straw into the ground, mixing it with the ground, preventing the crushed straw from being scattered by the wind, and improving compaction efficiency and resource utilization efficiency.

[0013] 2. When crushing straw, the first transmission disc drives the sliding column to rotate, which in turn drives the scraper to reciprocate above the arc groove, removing the crushed straw adhering to the arc groove. The operation is simple and quick, and it is convenient to clean the area above the arc groove. Attached Figure Description
