Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a screening machine for agricultural products with an anti-blocking structure. Background Art

[0002] A screening machine is a device used to separate materials by particle size. It typically consists of a screen, a vibrator, a motor, and a bracket. During operation, material enters the screening machine through the feed inlet. The vibrator then causes the screen to vibrate, causing the material to continuously bounce and roll across the screen. Due to the varying apertures of the screen, smaller particles pass through, while larger particles remain on the screen, thus separating the materials. Screening machines are widely used in the chemical, food, pharmaceutical, and mining industries for screening, grading, and filtering a variety of materials. Different types of screening machines are suitable for different materials and screening requirements. For example, a vibrating screen is suitable for screening materials with smaller particles, while a drum screen is suitable for screening materials with larger particles. Overall, screening machines are a very important piece of industrial equipment that can help companies improve production efficiency, ensure product quality, and reduce production costs.

[0003] When existing screening machines are used to screen some agricultural grains, the grains can easily get stuck in the mesh of the screen, causing the screen to be blocked and thus affecting the screening efficiency. Frequent manual cleaning is not convenient enough and requires the screening machine to be stopped, which also reduces the screening efficiency. Utility Model Content

[0004] The purpose of the present utility model is to provide a screening machine for agricultural products with an anti-clogging structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a screening machine for agricultural products with an anti-blocking structure, comprising a machine body and a bracket, wherein a feed port and a mounting plate are passed through and fixedly connected to the top surface of the machine body, a motor is fixedly connected to the surface of the mounting plate, and a control unit for improving screening efficiency and anti-blocking function is provided inside the machine body, wherein the control unit comprises:

[0006] The rotating shaft passes through the top of the machine body, the rotating shaft is rotatably connected to the machine body, the rotating shaft is passed through and fixedly connected by the output shaft of the motor. When the screening machine is in use, the grain to be screened is poured into the machine body through the feed port after the motor is started. When the output shaft of the motor drives the rotating shaft to rotate, the bottom end of the rotating shaft is fixedly connected with a gear shaft, the gear shaft passes through a rotating rod, the inner wall of the rotating rod is provided with a movable cavity, the bottom end of the gear shaft passes through and is rotatably connected with a support rod, the support rod passes through the movable cavity, and the support rod The bottom end is fixedly connected with an anti-slip plate, and the top surface of the anti-slip plate is fixedly connected with a spring. When the arc-shaped inclined surface block is interfered with by the interference of the interference rod, the rotating rod is pushed downward, and the anti-slip plate will move relatively upward, thereby causing the anti-slip plate to compress the spring in the movable cavity. When the arc-shaped inclined surface block rotates a certain distance and is no longer interfered with by the interference rod, the compressed spring will reset the rotating rod, so that the rotating rod can still move up and down a short distance when rotating. The end of the spring away from the anti-slip plate is fixedly connected to the inner wall of the movable cavity.

[0007] Preferably, the top surface of the rotating rod is fixedly connected to an arc-shaped inclined surface block, and the inner wall of the body is fixedly connected to a resistance rod. After the rotating rod rotates a certain distance, the arc of the arc-shaped inclined surface block fixedly connected to the top surface of the rotating rod will be resisted by the bottom end of the resistance rod fixedly connected to the inner wall of the body, thereby forcing the arc-shaped inclined surface block to push the rotating rod downward under the resistance of the resistance rod.

[0008] Preferably, a connecting rod passes through the top surface of the body, and the connecting rod is slidably connected to the body. Since the connecting rod passes through the body and is slidably connected, the connecting ring on the top of the connecting rod can also only move up and down due to the connecting rod.

[0009] Preferably, the top end of the connecting rod is fixedly connected with a connecting ring, and the inner side of the connecting ring is fixedly connected with a resistance block. When the rotating shaft rotates, since the connecting rod passes through the machine body and is slidably connected, the connecting ring on the top of the connecting rod can also only move up and down due to the connecting rod, and when the rotating shaft rotates, the arc-shaped groove on the surface of the rotating shaft will resist the resistance block.

[0010] Preferably, an arc-shaped sliding groove is provided on the surface of the rotating shaft, and the abutment block fixedly connected to the inner side of the connecting ring is inserted into the arc-shaped sliding groove provided on the surface of the rotating shaft.

[0011] Preferably, the bottom end of the connecting rod is fixedly connected to a screen frame, a screen is provided on the inner side of the screen frame, the rotating rod passes through the screen frame, and the resistance block drives the connecting ring to move up and down, then the connecting ring will drive the connecting rod to move up and down, so that the connecting rod drives the screen frame to move up and down and the screen also shakes up and down to actively screen and improve screening efficiency.

[0012] Preferably, the bottom surface of the rotating rod is fixedly connected to a rotating frame. When the rotating shaft rotates, the rotating shaft will first drive the rotating rod to rotate through the gear shaft, and then the rotating rod will drive the rotating frame fixedly connected to the bottom to rotate. A cleaning brush is provided on the top surface of the rotating frame.

[0013] Compared with the prior art, the present invention provides a screening machine for agricultural products with an anti-clogging structure, which has the following beneficial effects:

[0014] 1. The agricultural product screening machine with an anti-clogging structure has an arc-shaped inclined surface block fixedly connected to the top surface of the rotating rod and is interfered with by the bottom end of the interference rod fixedly connected to the inner wall of the machine body after the rotating rod rotates a certain distance, thereby forcing the arc-shaped inclined surface block to push the rotating rod downward under the interference action of the interference rod, and then the anti-slip plate will be relatively upward, thereby causing the anti-slip plate to compress the spring in the movable chamber. When the arc-shaped inclined surface block is no longer interfered with by the interference rod after rotating a certain distance, the compressed spring will reset the rotating rod, so that the rotating rod can still move up and down a short distance when rotating, and then the rotating frame at the bottom of the rotating rod will be located in the machine body and rotate and move up and down, so that the cleaning brush on the top surface of the rotating frame can also hit the screen when rotating to clean the screen, thereby avoiding clogging of the screen.

[0015] 2. The agricultural product screening machine with an anti-blocking structure has a connecting rod that penetrates the machine body and is slidably connected when the shaft rotates. Therefore, the connecting ring on the top of the connecting rod can only move up and down due to the connecting rod. When the shaft rotates, the arc-shaped groove on the surface of the shaft will contact the resistance block, thereby forcing the resistance block to drive the connecting ring to move up and down. Then the connecting ring will drive the connecting rod to move up and down, so that the connecting rod drives the screen frame to move up and down, and the screen will also shake up and down to actively screen and improve the screening efficiency.

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a screening machine for agricultural products with an anti-blocking structure, comprising a body 1 and a bracket 3, the top surface of the body 1 passes through and is fixedly connected with a feed port 4 and a mounting plate 5, the surface of the mounting plate 5 is fixedly connected with a motor 6, and the interior of the body 1 is provided with a control unit 2 for improving screening efficiency and anti-blocking function, and the control unit 2 comprises: a rotating shaft 21, a gear shaft 22, a rotating rod 23, a support rod 24, an anti-slip plate 25, an active cavity 26, a spring 27, an arc-shaped inclined block 28, a resistance rod 29, a connecting rod 210, a connecting ring 211, a resistance block 212, an arc-shaped slide 213, a screen frame 214, a screen 215, a rotating frame 216, and a cleaning brush 217.

[0023] The rotating shaft 21 passes through the top of the machine body 1, and the rotating shaft 21 is rotatably connected to the machine body 1. The rotating shaft 21 is penetrated and fixedly connected by the output shaft of the motor 6. When the screening machine is in use, after starting the motor 6, the grains to be screened are poured into the machine body 1 through the feed port 4. When the output shaft of the motor 6 drives the rotating shaft 21 to rotate, the bottom end of the rotating shaft 21 is fixedly connected to the gear shaft 22, and the gear shaft 22 passes through the rotating rod 23. The inner wall of the rotating rod 23 is provided with a movable cavity 26. The bottom end of the gear shaft 22 passes through and is rotatably connected to the support rod 24. The support rod 24 passes through the movable cavity 26, and the bottom end of the support rod 24 is fixedly connected to the anti- The anti-slip plate 25 and the top surface of the anti-slip plate 25 are fixedly connected with a spring 27. The arc-shaped inclined surface block 28 pushes the rotating rod 23 downward under the interference of the interference rod 29, so that the anti-slip plate 25 will be relatively upward, thereby causing the anti-slip plate 25 to compress the spring 27 in the movable cavity 26. When the arc-shaped inclined surface block 28 rotates a certain distance and is no longer interfered with by the interference rod 29, the compressed spring 27 will reset the rotating rod 23, so that the rotating rod 23 can also move up and down a short distance when rotating. The end of the spring 27 away from the anti-slip plate 25 is fixedly connected to the inner wall of the movable cavity 26. The top surface of the rotating rod 23 is fixedly connected to an arc-shaped inclined surface block 28, and the inner wall of the body 1 is fixedly connected to a resistance rod 29. After the rotating rod 23 rotates a certain distance, the arc of the arc-shaped inclined surface block 28 fixedly connected to the top surface of the rotating rod 23 will be interfered with by the bottom end of the resistance rod 29 fixedly connected to the inner wall of the body 1, thereby forcing the arc-shaped inclined surface block 28 to push the rotating rod 23 downward under the interference of the resistance rod 29. A connecting rod 210 passes through the top surface of the body 1 and is slidably connected to the body 1. Because the connecting rod 210 passes through the body 1 and is slidably connected, the connecting ring 211 at the top of the connecting rod 210 can also only move up and down due to the connecting rod 210. The top of the connecting rod 210 is fixedly connected to a connecting ring 211, and the inner side of the connecting ring 211 is fixedly connected to a resistance block 212. When the rotating shaft 21 rotates, since the connecting rod 210 passes through the body 1 and is slidably connected, the connecting ring 211 at the top of the connecting rod 210 can also only move up and down due to the connecting rod 210. When the rotating shaft 21 rotates, the arc-shaped groove 213 on the surface of the rotating shaft 21 will resist the resistance block 212.

[0024] The surface of the rotating shaft 21 is provided with an arc-shaped chute 213, and the abutment block 212 fixedly connected to the inner side of the connecting ring 211 is inserted into the arc-shaped chute 213 provided on the surface of the rotating shaft 21. The bottom end of the connecting rod 210 is fixedly connected to a screen frame 214, and a screen 215 is provided on the inner side of the screen frame 214. The rotating rod 23 passes through the screen frame 214, and the abutment block 212 drives the connecting ring 211 to move up and down. Then, the connecting ring 211 drives the connecting rod 210 to move up and down, so that the connecting rod 210 drives the screen frame 214 to move up and down, and the screen 215 also shakes up and down to actively screen and improve screening efficiency. The bottom surface of the rotating rod 23 is fixedly connected to the rotating frame 216. When the rotating shaft 21 rotates, the rotating shaft 21 will first drive the rotating rod 23 to rotate through the gear shaft 22, and then the rotating rod 23 will drive the rotating frame 216 fixed to the bottom to rotate. A cleaning brush 217 is provided on the top surface of the rotating frame 216.

[0025] Based on the above embodiment, when the screening machine is in use, after starting the motor 6, the grains to be screened are poured into the machine body 1 through the feed port 4, and the output shaft of the motor 6 drives the rotating shaft 21 to rotate. When the rotating shaft 21 rotates, the rotating shaft 21 first drives the rotating rod 23 to rotate through the gear shaft 22, and then the rotating rod 23 drives the rotating frame 216 fixedly connected to the bottom to rotate. After the rotating rod 23 rotates a certain distance, the arc of the arc-shaped inclined surface block 28 fixedly connected to the top surface of the rotating rod 23 will be interfered with by the bottom end of the interference rod 29 fixedly connected to the inner wall of the machine body 1, thereby forcing the arc-shaped inclined surface block 28 to rotate under the interference rod 29. The rotating rod 23 is pushed downward by the interference, and the anti-slip plate 25 will be relatively upward, thereby causing the anti-slip plate 25 to compress the spring 27 in the movable chamber 26. When the arc-shaped inclined surface block 28 rotates a certain distance and is no longer interfered with by the interference rod 29, the compressed spring 27 will reset the rotating rod 23, so that the rotating rod 23 can still move up and down a short distance when rotating. Then, the rotating frame 216 at the bottom of the rotating rod 23 will be located in the body 1 and rotate and move up and down, so that the cleaning brush 217 on the top surface of the rotating frame 216 can also hit the screen 215 when rotating the cleaning screen 215, to prevent the screen 215 from being blocked.

[0026] At the same time, when the rotating shaft 21 rotates, since the connecting rod 210 passes through the body 1 and is slidably connected, the connecting ring 211 on the top of the connecting rod 210 can also only move up and down due to the connecting rod 210. When the rotating shaft 21 rotates, the arc-shaped slide groove 213 on the surface of the rotating shaft 21 will contact the resistance block 212, thereby forcing the resistance block 212 to drive the connecting ring 211 to move up and down. Then the connecting ring 211 will drive the connecting rod 210 to move up and down, so that the connecting rod 210 drives the screen frame 214 to move up and down, and the screen 215 also shakes up and down to actively screen and improve the screening efficiency.

[0027] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
