Description

Technical Field

[0001] This utility model relates to the field of threshing machine technology, specifically to an anti-blocking mechanism for a threshing machine. Background Technology

[0002] A corn kernel stripping device for corn threshing, patent number CN209030634U, utilizes a high-speed rotating threshing roller to continuously act on the corn, thereby completing the high-speed threshing operation and significantly improving processing efficiency. However, the threshed corn kernels may become stuck between the outer protrusions of the threshing roller under the pressure between the threshing roller and the threshing trough. At the same time, the fallen corn kernels and corn cobs need to be screened. A large accumulation of corn kernels may cause blockage of the screen plate, which can easily affect subsequent threshing and screening operations. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an anti-clogging mechanism for a threshing machine, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a threshing machine anti-blocking mechanism, comprising a receiving cylinder, with fixed frames fixedly connected to both sides of the inner cavity of the receiving cylinder. The bottom of each fixed frame has an embedded groove, and a filter screen is fixedly connected to one side of each of the two embedded grooves via an elastic sealing connecting strip. One side of the elastic sealing connecting strip is fixedly connected to the inner cavity of the receiving cylinder. Partition plates are provided on both sides of the inner cavity of the receiving cylinder. A steel wire rope driven by an electric hoist slides through the inner cavity of the receiving cylinder. The bottom end of the steel wire rope forks into two strands, and the bottom end of the steel wire rope penetrates the partition plate and extends below it. The surface of the steel wire rope is slidably connected to the inner cavity of the partition plate. The ends of the two steel wire ropes form a rectangle with four strands. A lever is rotatably connected to the steel wire ropes on the long sides of the two rectangles. A discharge port is provided on the surface of the receiving cylinder. One side of the inlet is connected to a guide channel. During use, the threshed agricultural products are conveyed into the receiving cylinder, where they are filtered through a filter screen. During filtration, electric hoists on both sides pull the steel wire ropes up and down, causing the filter screen to vibrate irregularly left and right below the embedded groove for shaking filtration. The elastic sealing connection belt prevents leakage. During vibration, the actuating rod moves inside the crop, accelerating the descent of the crop. The filtered crop falls to the bottom and is output through the outlet. When the filter screen becomes clogged, the drive mechanism is activated to drive the push plate to rise, and then pushes the filter screen through the stepped groove to the bottom of the fixed frame for positioning. Then, the needle is inserted into the inside of the filter screen to unclog the internal filter holes, and then it is reset. This allows for quick cleaning of the filter screen. The screened crop impurities can also be cleaned by opening the cylinder door on the surface of the receiving cylinder.

[0005] As a further embodiment of this utility model: each of the opposite sides of the fixing frame is provided with an inclined surface, which facilitates the falling of threshed grains and forms a slope.

[0006] As a further embodiment of this utility model: the receiving cylinder is rotatably connected to a guide wheel in the inner cavity of the partition plate, and the guide wheel is respectively connected to the two forked strands of the steel wire rope.

[0007] As a further embodiment of this utility model: the inner cavity of the receiving cylinder is slidably connected to a push plate driven by a driving mechanism, the push plate is located below the filter screen, and the top of the push plate is fixedly connected to a needle corresponding to the filter screen holes one by one.

[0008] As a further embodiment of this utility model: stepped grooves adapted to the bottom of the two fixed frames are respectively opened on both sides of the push plate. When the stepped grooves are engaged with the fixed frame, the filter screen can be pushed and squeezed under the bottom embedded groove of the fixed frame for positioning. Then, the needle can be inserted into the filter hole in the filter screen for cleaning to prevent the filter screen from clogging.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] 1. In this utility model, during filtration, the electric hoists on both sides pull the steel wire ropes up and down, causing the filter screen to vibrate irregularly left and right below the inner groove, thus performing vibration filtration. The elastic sealing connecting belt prevents leakage. During vibration, the actuating rod can also be driven to move inside the crop, accelerating the descent speed of the crop. The filtered crop falls below and is output through the discharge port.

[0011] 2. In this utility model, when the filter screen is clogged, the drive mechanism is activated to drive the push plate to rise, and then the filter screen is pushed to the bottom of the fixed frame for positioning through the stepped groove. Then, the needle is inserted into the inside of the filter screen to unclog the internal filter holes, and then it is reset. This can quickly clean the filter screen, and the screened crop impurities can be cleaned by opening the cylinder door on the surface of the receiving cylinder. Attached Figure Description
