Description

Technical Field

[0001] The utility model relates to the technical field of seed cleaning for crop cultivation, and specifically relates to a seed cleaning device for crop cultivation. Background Technique

[0002] With the increasing mechanization of agricultural production, the production efficiency has been improved. In the process of agricultural production, seed selection of crop grains is a very important link, and high-quality seeds are an important guarantee for crop yields. Inevitably, some straws, gravels and other sundries will be mixed in the process of seed harvesting. Therefore, the process of seed cleaning is a very important link.

[0003] However, some seed cleaning devices for crop cultivation generally use air-screen cleaners, which use the fact that the weight of seeds is greater than that of impurities such as broken straws and broken leaves to achieve the operation of blowing away impurities. However, during the impurity removal process, light impurities such as broken straws and broken leaves will be discharged from the air outlet pipe of the air separator, which is likely to diffuse and pollute the working place. The diffusion of fine debris not only affects the respiratory health of workers, but also increases the cleaning workload additionally. Therefore, it does not meet the existing requirements, and for this reason, we propose a seed cleaning device for crop cultivation. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a seed cleaning device for crop cultivation. To solve the above technical problems, the technical solution of the utility model is as follows:

[0005] A seed cleaning device for crop cultivation includes an air separator body. The upper end of the air separator body is connected through a feed hopper. Below the feed hopper and on one side of the air separator body, there is an air outlet pipe connected. On one side of the bottom of the air separator body, there is a discharge port. The port of the air outlet pipe is fixedly connected with a fixed frame. On the side of the fixed frame away from the air outlet pipe, there is a docking frame docked. Inside the docking frame, there is a filter screen fixedly connected, and a miscellaneous matter blocking cloth sleeve is fixed at the end of the filter screen away from the air outlet pipe.

[0006] Preferably, a connection groove is opened on the inner wall of the air outlet pipe near the fixed frame, and a connection frame docked with the connection groove is fixedly connected to the end of the docking frame away from the miscellaneous matter blocking cloth sleeve.

[0007] Preferably, fixing blocks are fixedly connected to the left and right sides of the upper and lower ends of the fixed frame. A sliding groove is opened on the surface of each fixing block, and support blocks are fixedly connected to the sides of the left and right fixing blocks away from each other.

[0008] Preferably, a limiting block is slidably connected inside the sliding groove. One side of the limiting block close to the supporting block is fixedly connected with a connecting rod that movably penetrates through the limiting block. A spring is fixedly connected between the mutually approaching sides of the limiting block and the supporting block, and the spring is wound around the outer surface of the connecting rod.

[0009] Preferably, one end of the connecting rod extending through the outside of the supporting block is fixedly connected with a connecting plate. One end of the bottom side of the connecting plate close to the connecting rod is fixedly connected with a limiting rod.

[0010] Preferably, docking grooves are respectively opened at the upper and lower sides of both sides of the surface of the fixed frame. Vertically arranged plates inserted into the docking grooves are respectively fixedly connected to the upper and lower sides of the docking frame close to the fixed frame. A limiting hole matching the limiting rod is opened on the surface of the vertically arranged plate, and the limiting rod is inserted into the corresponding limiting hole.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By pushing the limiting block, the limiting block moves along the sliding groove towards the side close to the supporting block, thereby squeezing the spring to generate deformation, driving the connecting plate and the limiting rod away from the fixed frame. Then, the docking frame provided with the filter net and the impurity-blocking cloth sleeve is docked with the fixed frame, so that the vertically arranged plate is inserted into the docking groove, and the connecting frame is inserted into the inside of the connecting groove, thereby initially connecting the air outlet pipe with the filter net and the impurity-blocking cloth sleeve. Then, the pushing of the limiting block is released, so that the spring releases its elastic force, thereby driving the connecting plate and the limiting rod to move towards the side close to the fixed frame, and making the limiting rod clamped inside the limiting hole, thereby fixing and connecting the docking frame provided with the filter net and the impurity-blocking cloth sleeve with the air outlet pipe. This is convenient for installation and also convenient for disassembling and cleaning it.

[0013] 2. The present utility model can block sundries through the filter net, so that they fall and accumulate inside the connecting frame, while the impurity-blocking cloth sleeve can filter the air flow and prevent debris from flying and polluting the workplace.
