Description

Technical Field

[0001] The utility model relates to the technical field of agricultural waste treatment, in particular to a straw cutting device. Background Art

[0002] Agricultural waste is also called agricultural garbage. Its components mainly include two categories: plant fiber waste and livestock and poultry manure. If these materials are discarded, it will cause energy loss and environmental pollution. In the past, these wastes were mostly used as fuel or incinerated on site and other simple and extensive methods for treatment, which not only caused a huge waste of resources, but also brought heavy pressure to the environment. For example, crop straw is an important waste in agricultural production and needs to be processed and reused. However, existing agricultural waste treatment devices cannot directly process longer crop straws. They need to be cut into segments in other processing equipment before being crushed. There are many equipment and the cost is high. Existing agricultural waste treatment devices cannot guarantee uniform crushing when crushing crop straw.

[0003] For example, in the prior art, the Chinese utility model with announcement number CN213245788U discloses a device for resource utilization and treatment of agricultural waste. This utility model can process long straw and complete the processes of cutting and crushing. It requires few devices and has low cost. It can not only crush the straw twice to ensure that the straw is completely crushed, but also push the straw downward to prevent it from blocking the feeding channel.

[0004] Through the above-mentioned agricultural waste resource utilization and processing device, it can be known that the existing technology has the following problems: when crushing crop straw, it is impossible to ensure that the crushing is completed evenly, so we need to propose a straw cutting device. Summary of the Invention

[0005] The purpose of the utility model is to provide a straw cutting device that can conveniently feed crop straw, effectively ensure the stability of crop cutting, facilitate the crushing of crops by the crusher, further reduce the blockage during the straw crushing process, and improve the crushing effect, so as to solve the problems raised in the above background technology.

[0007] Preferably, the electric push rod is installed on the top of the mounting frame, the protruding end of the electric push rod is connected to the top of the lifting frame, and limiting guide grooves are provided at both ends of the lifting frame.

[0008] Preferably, the inner wall of the mounting frame is connected to a limiting guide rod, the inner wall of the limiting guide groove is slidably connected to the surface of the limiting guide rod, the top of the cutter is installed with a positioning shaft, and the top of the positioning shaft is inserted into the top of the lifting frame.

[0009] Preferably, a locking sleeve is threadedly mounted on the top end of the positioning shaft, a servo motor is mounted on the surface of the limiting frame, and the output end of the servo motor is transmission-connected to the surface of the assembly pressure plate.

[0010] Preferably, the limiting and clamping assembly includes: a sliding seat slidably mounted on the inner wall of the assembly groove, and a limiting slider connected to the two side surfaces of the sliding seat; wherein, a limiting slide groove is opened on the inner wall of the assembly groove, and the surface of the limiting slider is slidably connected to the inner wall of the limiting slide groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

When the crop straw is transported by the conveyor, the servo motor drives the assembly pressure plate to rotate, and cooperates with the compression spring inside the assembly groove to make the sliding seat cooperate with the limiting slider to move outward along the limiting slide groove, pressing the material pressing cross bar onto the crop straw, thereby improving the compacting effect of the crop straw, cooperating with the conveyor to improve the stability of straw transportation, effectively preventing the straw from being scattered, and facilitating the electric push rod to drive the lifting frame so that the cutter can press and cut the straw, thereby improving the efficiency of straw cutting and effectively reducing the blockage of the crusher during crushing.
