Description

Technical Field

[0001] This utility model relates to the field of straw feed processing technology, specifically a shovel-type straw powderer with staggered bottom blades. Background Technology

[0002] The shredder-type grass powdering mechanism is a highly efficient grass pulverizing device. It uses a high-speed rotating blade to impact and cut the grass, thus pulverizing it. This mechanism is characterized by its small size, light weight, high power, and good pulverizing effect. It is suitable for weeding, pulverizing, and returning grass to the field in environments such as orchards and farmland, which can improve work efficiency and reduce labor costs.

[0003] The shovel-type straw powdering mechanism uses a high-speed rotating blade to impact and cut straw, pulverizing it into fine particles. It is suitable for weeding and pulverizing straw for returning to the field in environments such as orchards and farmland. Therefore, a shovel-type straw powdering machine is required. However, straw with excessive moisture may be difficult to pulverize due to stickiness, while straw with excessive moisture may be over- or under-pulverized due to increased brittleness. Uneven pulverization and excessively long straw may lead to uneven distribution of straw in the soil after returning to the field, with some areas having too much or too little straw, affecting soil structure and fertility. Unevenly pulverized straw may also cause uneven processing due to size differences during subsequent composting or biomass energy utilization, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a shredder with staggered bottom blades to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blade-type grass powderer with staggered bottom blades, comprising a grass powderer body, and further comprising:

[0006] A motor housing is located on one side of the grass powder machine body. The inner cavity of the motor housing is equipped with a rotating shaft. An installation plate is fixedly connected to the outer side of the rotating shaft. A screen plate is provided on the outer side of the rotating shaft. Multiple sets of perforations are opened on the inner wall of the installation plate. An inclined flow plate is provided on the outer side of the rotating shaft.

[0007] A connecting shaft is provided on one side of the grass powder machine body. A blade shaft is provided at one end of the connecting shaft. A blade flange is fixedly connected to the outer side of the blade shaft. A blade cylinder is fixedly connected to the inner wall of the blade flange. A blade body is fixedly connected to the outer side of the blade cylinder.

[0008] Preferably, a conveyor shaft for conveying straw is fixedly connected to the outer side of the rotating shaft.

[0009] Preferably, a mounting column is fixedly connected to the outer side of the rotating shaft, and a connecting plate is installed on one side of the inclined plate.

[0010] Preferably, the inner wall of the connecting plate is threaded with a fixing screw for engaging the diagonal flow plate, and the outer side of the rotating shaft is fixedly connected with a connecting plate.

[0011] Preferably, a housing is installed on one side of the grass powder machine body, and a positioning column is fixedly connected to one end of the connecting shaft.

[0012] Preferably, a gasket for mounting the cutter cylinder is installed on one side of the cutter flange.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model features blade flanges installed on a blade shaft in a uniformly distributed arrangement, ensuring uniform mass distribution of the blade flanges on the blade shaft. In actual operation, the blade shaft is less prone to severe vibration, guaranteeing stable operation of the mechanism and maintaining dynamic balance to avoid resonance. Furthermore, it allows for the selection and installation of appropriate blade bodies according to different usage requirements. The blade bodies and blade cylinders are staggered and fixed to the blade flanges, with the blade flanges connected to each other via cylinders. The blade cylinders and blade bodies on the same horizontal line are staggered and fixed to the blade flanges by being installed at corresponding connection holes. Thus, when the blade shaft rotates, the blade bodies work together to uniformly crush the straw. Attached Figure Description

[0026] Working principle: First, straw feed is added from above the main body 1 of the straw powderer. The motor inside the motor housing 2 rotates, driving the rotating shaft 3 to rotate. The rotating shaft 3 rotates, driving the mounting column 8 to rotate. The rotating column 8 rotates, driving the inclined plate 9 to rotate. Straw feed that does not meet the required crushing length is screened and crushed further to prevent uneven crushing. It then falls below the main body 1 of the straw powderer. During operation, the motor inside the housing 13 drives the connecting shaft 14 to rotate. The rotating connecting shaft 14 rotates, driving the positioning column 15 to rotate. The rotating positioning column 15 rotates, driving the throwing blade shaft 16 to rotate. The rotating throwing blade shaft 16 rotates, driving the throwing blade flange 17 to rotate. The rotating throwing blade flange 17 rotates, driving the throwing blade cylinder 19 to rotate. The rotating throwing blade cylinder 19 rotates, driving the throwing blade body 20 to rotate. During the rotation, the throwing blade body 20 collides with the straw, crushing the straw under the action of force. By controlling the number of throwing blades, the collision length between the straw and the throwing blades can be increased or decreased, thereby achieving the desired straw crushing length.
