Detailed Implementation

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-6 This utility model provides a multi-purpose threshing machine with automatic cleaning function, comprising: a housing 1, a filter screen 5 inside the housing 1, the diameter of the through holes on the filter screen 5 being larger than the aperture of the metal screen 11, both sides of one end of the filter screen 5 being rotatably connected to the inner wall of the housing 1, so that the filter screen 5 can be tilted at a certain angle, an electric telescopic rod 15 being fixedly connected to the inner wall of the housing 1 for pushing the filter screen 5 to tilt, and a sliding frame 14 being slidably connected to the lower surface of the other end of the filter screen 5, which can be prevented from falling off by the interaction of the T-shaped slider and the T-shaped groove, and the interior of the sliding frame 14 being rotatably connected to the upper end of the electric telescopic rod 15; Inside the housing 1, a filter frame 9 is slidably connected via a slider. The four corners of the inner wall of the filter frame 9 are fixedly connected to slide rods 19 via fixing plates. The slide rods 19 are used to limit the movement of the metal screen 11. The metal screen 11 is installed inside the filter frame 9. The inside of the metal screen 11 is slidably connected to the inside of the slide rods 19. A spring 20 is fixedly connected between the lower surface of the metal screen 11 and the upper surface of the fixing plate, so that the metal screen 11 can move up and down. A vibration motor 10 is fixedly connected to the lower surface of the metal screen 11, which can drive the metal screen 11 to move up and down.

[0020] The upper surface of the box 1 is fixedly connected to the threshing box 2. Multiple placement rods 7 are set inside the threshing box 2. The two ends of the placement rods 7 are fixedly connected to the inner wall of the threshing box 2, so that the soybean straw to be threshed can be placed on the placement rods 7.

[0021] A motor 6 is fixedly connected to the side of the threshing box 2. A rotating rod 12 is fixedly connected to the output end of the motor 6. The end of the rotating rod 12 away from the motor 6 is rotatably connected to the inner wall of the threshing box 2. Multiple mounting rings 8 are fixedly connected to the outside of the rotating rod 12. A hanging column 16 is fixedly connected to the side of the mounting ring 8. The mounting ring 8 is rotatably connected to the auxiliary rod 18 through a T-shaped column. A tension spring 17 is connected between the lower end of the auxiliary rod 18 and the hanging column 16. The motor 6 drives the rotating rod 12 to rotate, thereby driving the mounting ring 8 and the auxiliary rod 18 to rotate synchronously, which can perform threshing by striking. The tension spring 17 pulls the auxiliary rod 18 vertically upward, which facilitates threshing by striking and can prevent the straw from being hooked.

[0022] Spring 20 is sleeved on the outside of slide bar 19.

[0023] Multiple through holes are opened on the upper surface of the filter screen plate 5. The filter screen plate 5 is set on the upper part of the metal screen 11 and can screen out impurities larger than the diameter of the through holes.

[0024] The second sealing door 4 is hinged to the side of the box body 1. A handle is fixedly connected to the side of the second sealing door 4. The second sealing door 4 can be opened by pulling the handle.

[0025] The first sealing door 3 is hinged to the upper surface of the threshing box 2.

[0026] The third sealing door 13 is hinged to the side of the housing 1 via a hinge, and the third sealing door 13 is located on the right side of the filter screen 5.

[0027] Working principle: During use, the operator places the soybeans to be threshed on the placement rod 7, and then starts the motor 6 through the controller to drive the rotating rod 12 and the auxiliary rod 18 to rotate, striking the crop straw and causing the crop grains to fall onto the filter screen 5. The filter screen 5 can filter out larger diameter impurities, causing the soybeans to fall onto the upper surface of the metal screen 11. At the same time, the vibration motor 10 at the bottom of the metal screen 11 is started, causing the metal screen 11 to vibrate up and down on the sliding rod 19, which can increase the filtration efficiency and cause smaller diameter impurities to fall to the bottom of the box 1. Then the operator can open the second sealing door 4, slide out the filter frame 9, and take out the filtered soybeans. When too much impurity accumulates on the filter screen 5, the operator can open the third sealing door 13 and then start the electric telescopic rod 15 to push one end of the filter screen 5 upward to facilitate the discharge of accumulated impurities. Then the operator can take out the straw and then process it.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
