Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically a dust suppression feeding device for agricultural product processing. Background Technology

[0002] Dust suppression during material handling refers to the use of reasonable design and technical means in agricultural product processing, especially in material handling, feeding, and processing stages, to reduce the generation and diffusion of dust in the air, thereby protecting worker health, improving production efficiency, and enhancing product quality. Key measures include: equipment design: using enclosed or semi-enclosed conveying equipment (such as pneumatic conveyors and chain conveyors) to prevent dust leakage; feeding control: using low-speed material drop, buffer devices, or airflow-assisted equipment during the feeding process to reduce the material's falling height, minimizing impact and dust generation; water spraying for dust suppression: timely spraying during processing to increase air humidity and reduce dust suspension; and dust collection: installing efficient dust removal equipment (such as bag filters and electrostatic precipitators) to effectively collect and treat dust.

[0003] Patent application CN202010981765.3 discloses a drying device for agricultural product processing, comprising a shell, rollers, clamps, electric heating mesh, and a fan. In this patent's technical solution, the electric heating mesh and fan blow external air onto the mesh and into the shell, replacing the traditional irradiation baking method with a hot air method for drying agricultural products. The hot air circulates within the shell, maintaining a relatively uniform temperature throughout. Since the clamps are mounted on the rollers, which are rotatably mounted within the shell, when the fan blows hot air onto the clamps, the clamps rotate around the central axis of the rollers within the shell under the force of the airflow. This rotation ensures that each clamp receives a relatively consistent frequency of direct hot airflow, and that the air passes through various positions within the shell's interior in turn. Therefore, the agricultural products on the clamps are heated relatively evenly, ensuring consistent drying levels for products processed in the same batch.

[0004] When soybeans are poured into processing tanks for processing, dust from the soybeans is released into the air during the pouring process, affecting the surrounding working environment and harming the health of the operators. Therefore, a dust suppression and feeding device for agricultural product processing is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a dust suppression and feeding device for agricultural product processing, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a dust suppression and feeding device for agricultural product processing, comprising a workbench, a receiving frame fixedly connected to the top of the workbench, a dust suction device provided on the top of the workbench, a feeding device provided on the inner wall of the receiving frame, and a dust removal device provided at the bottom of the workbench; the dust suction device includes a suction pipe, a fixing plate, a collection tank, a motor, a rotating rod, a filter screen, a stirring plate, a T-shaped plate, and a processing tank; the suction pipe is fixedly connected to the inner wall of the receiving frame, and the fixing plate is fixedly connected to the left side of the receiving frame. The collection tank is fixedly connected to the top of the workbench. When soybeans are poured for processing, dust generated by the suction fan inside the suction duct is drawn into the collection tank, effectively reducing dust during the pouring process and preventing it from scattering into the air, thus maintaining environmental hygiene. Furthermore, dust generated during the pouring process can affect the health of operators, leading to respiratory problems. The suction duct improves the working environment for workers, ensuring their health and safety. The processing tank is fixedly connected to the bottom of the workbench, and the motor is fixedly connected to the bottom of the processing tank. The rotating rod is fixedly... The filter screen is fixedly installed on the inner wall of the processing tank, the stirring plate is fixedly connected to the circumferential surface of the rotating rod, the T-shaped plate is fixedly connected to the outer surface of the stirring plate, the left side surface of the T-shaped plate is in contact with the inner wall of the processing tank, the circumferential surface of the rotating rod is rotatably connected to the inner wall of the processing tank, the end of the suction pipe away from the receiving frame is fixedly connected to the top of the fixed plate, the top of the collection tank is fixedly connected to the bottom of the fixed plate, the collection tank is equipped with an exhaust fan, and the circumferential surface of the rotating rod is rotatably connected to the inner wall of the receiving frame. The bottom of the mold plate is in contact with the top of the filter screen. The rotating rod is rotatably connected to the filter screen. The rotating rod drives the rotating rod to rotate, which in turn drives the stirring plate to rotate. The soybeans that have been poured in are stirred by the rotating stirring plate, so that the mud and sand in the soybeans are filtered through the filter screen. This makes the filtered soybeans easier to process, reduces working costs, and improves work efficiency. The rotation of the stirring plate drives the T-shaped plate to rotate, and the rotation of the T-shaped plate scrapes off the dust attached to the inner wall of the processing tank, preventing the dust from falling back onto the filtered soybeans and enhancing the filtration effect.

[0007] Preferably, the feeding device includes a first guide plate, a second guide plate, a chute plate, a slide plate, and a screen frame. The first guide plate is fixedly connected to the top of the T-shaped plate, and the screen frame is slidably connected to the inner wall of the receiving frame. Rotation of the T-shaped plate drives the first guide plate to rotate. When the first guide plate rotates, it contacts the second guide plate, causing the second guide plate to move upwards via the inclined guide surface. The upward movement of the second guide plate drives the screen frame upwards, which in turn drives the slide plate upwards. The upward movement of the slide plate causes the spring telescopic column to extend and retract, causing the screen frame to move up and down reciprocally, pouring soybeans into the screen frame. This reciprocating movement of the screen frame ensures that the material enters the feed inlet evenly, helping to avoid the accumulation or uneven distribution of agricultural products, thereby improving the efficiency and quality of subsequent processing. The second feeding plate is fixedly connected to the bottom of the screen frame, the chute plate is fixedly connected to the inner wall of the receiving frame, and the slide plate is slidably connected to the inner wall of the chute plate. The feeding device also includes a spring telescopic column, a first hinge plate, a fixed column, and a second hinge plate. The spring telescopic column is fixedly connected to the top of the slide plate, the first hinge plate is slidably connected to the inner wall of the screen frame, the fixed column is fixedly connected to the top of the first hinge plate, and the second hinge plate is fixedly connected to the inner wall of the fixed column. The top of the second hinge plate is fixedly connected to the bottom of the receiving frame, and the top of the spring telescopic column is fixedly connected to the inner wall of the chute plate. Simultaneously, as the screen frame moves up and down, it contacts the first hinge plate, causing the first hinge plate to open and close intermittently as the screen frame moves downwards. This ensures uniform feeding of soybeans and improves the machine's production efficiency.

[0008] Preferably, the dust removal device includes a scraper, a fixed plate three, an L-shaped striking plate, a rocker plate, a connecting column, a hinged plate three, and a collection box. The scraper is fixedly connected to the circumferential surface of the rotating rod. When the dust suppression and feeding device for agricultural product processing is started, the rotating rod drives the scraper to rotate, and the scraper removes the dust filtered from the filter screen in the processing tank. When the machine is covered in dust, manual cleaning is required, reducing work efficiency. Removing dust by rotating the scraper maintains the equipment's optimal working condition and improves machine efficiency. The fixed plate three is fixedly connected to the bottom of the filter screen. The L-shaped striking plate is hinged to the inner wall of the fixed plate three by a torsion spring. The collection box is fixed... Connected to the bottom of the processing tank, the connecting column is hinged to the inner wall of the collection box via a torsion spring. The rocker arm is fixedly connected to the circumferential surface of the connecting column, and the hinge plate three is fixedly connected to the circumferential surface of the connecting column. The outer wall of the hinge plate three is in contact with the inner wall of the collection box, and the bottom of the scraper is in contact with the inner wall of the processing tank. When the scraper rotates, it will contact the rocker arm, causing the rocker arm to rotate. The rotation of the rocker arm drives the hinge plate three to rotate, and at the same time, the torsion spring in the connecting rod drives the hinge plate three to reset. When the hinge plate three rotates, it will open and close intermittently, collecting the dust scraped by the scraper into the collection box, making it easier to centrally dump the collected dust and improving the overall working efficiency of the machine.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This dust suppression and feeding device for agricultural product processing operates in coordination with a suction duct, a fixed plate, a collection tank, a motor, a rotating rod, a filter screen, a stirring plate, a T-shaped plate, and a processing tank. The suction fan inside the suction duct draws the dust generated during the pouring of soybeans into the collection tank, effectively reducing dust during the pouring process and preventing it from scattering into the air, thus maintaining environmental hygiene. Dust generated during the pouring process can affect the health of operators, leading to respiratory problems. The suction duct improves the working environment for workers, ensuring their health and safety. The motor drives the rotating rod, which in turn rotates the stirring plate, agitating the poured soybeans. This allows dirt and sand in the soybeans to be filtered through the filter screen, making the filtered soybeans easier to process, reducing operating costs and increasing efficiency. The rotating stirring plate also drives the T-shaped plate, which scrapes away dust adhering to the inner wall of the processing tank, preventing dust from falling back onto the filtered soybeans and enhancing the filtration effect.

[0010] 2. This dust suppression and feeding device for agricultural product processing operates through the coordinated operation of guide plate one, guide plate two, chute plate, slide plate, spring telescopic column, screen frame, hinge plate one, fixed column, hinge plate two, and fixed plate two. The rotation of the T-shaped plate drives guide plate one to rotate. When guide plate one rotates, it contacts guide plate two, causing guide plate two to move upwards via the guide inclined surface. The upward movement of guide plate two drives the screen frame upwards, which in turn drives the slide plate upwards. The upward movement of the slide plate causes the spring telescopic column to extend and retract, causing the screen frame to move up and down reciprocally. This pours soybeans into the screen frame. The reciprocating movement of the screen frame ensures that the material enters the feed inlet evenly, helping to avoid the accumulation or uneven distribution of agricultural products, thereby improving the efficiency and quality of subsequent processing. Simultaneously, the reciprocating movement of the screen frame contacts hinge plate one, causing hinge plate one to open and close intermittently when the screen frame moves downwards, ensuring even feeding of soybeans and improving the machine's production efficiency.

[0011] 3. This dust suppression and feeding device for agricultural product processing works in coordination with a scraper, a fixed plate, an L-shaped striking plate, a rocker plate, a connecting column, a hinge plate, and a collection box. When the device is started, the rotating rod drives the scraper to rotate, scraping away the dust filtered from the screen onto the processing tank. Previously, the machine was covered in dust, requiring manual cleaning, which reduced efficiency. The scraper's rotation helps maintain optimal equipment performance and improves efficiency. The scraper's rotation also contacts the rocker plate, causing it to rotate. This rotation, in turn, drives the hinge plate to rotate, and the torsion spring in the connecting rod resets the hinge plate. The rotating hinge plate intermittently opens and closes, collecting the dust scraped by the scraper into the collection box for convenient and centralized disposal, thus improving overall machine efficiency.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-7One embodiment of the present invention is as follows: a dust suppression and feeding device for agricultural product processing, comprising a workbench 1, a receiving frame 2 fixedly connected to the top of the workbench 1, a dust suction device 3 provided on the top of the workbench 1, a feeding device 4 provided on the inner wall of the receiving frame 2, and a dust removal device 5 provided on the bottom of the workbench 1; the dust suction device 3 includes a suction pipe 301, a fixing plate 302, a collection tank 303, a motor 304, a rotating rod 305, a filter screen 306, a stirring plate 307, a T-shaped plate 308, and a processing tank 309; the suction pipe 301 is fixedly connected to the inner wall of the receiving frame 2, the fixing plate 302 is fixedly connected to the left side of the receiving frame 2, and the collection tank 303 is fixedly connected to the processing tank 309. When the dust suppression and feeding device for agricultural product processing is activated at the top of workbench 1, the dust generated during the pouring and processing of soybeans is drawn into collection tank 303 by the suction fan inside suction duct 301. This effectively reduces the dust generated during the pouring process, prevents dust from scattering into the air, and maintains environmental hygiene. Simultaneously, dust generated during the pouring process can affect the health of operators, leading to respiratory problems. Dust extraction through suction duct 301 improves the working environment for workers, ensuring their health and safety. Processing tank 309 is fixedly connected to the bottom of workbench 1, motor 304 is fixedly connected to the bottom of processing tank 309, and rotating rod 305 is fixedly connected to motor 304. At the output end of 04, the filter screen 306 is fixedly installed on the inner wall of the processing tank 309, the stirring plate 307 is fixedly connected to the circumferential surface of the rotating rod 305, the T-shaped plate 308 is fixedly connected to the outer surface of the stirring plate 307, the left side surface of the T-shaped plate 308 is in contact with the inner wall of the processing tank 309, the circumferential surface of the rotating rod 305 is rotatably connected to the inner wall of the processing tank 309, the end of the suction pipe 301 away from the receiving frame 2 is fixedly connected to the top of the fixed plate 302, the top of the collection tank 303 is fixedly connected to the bottom of the fixed plate 302, the collection tank 303 is equipped with an exhaust fan, the circumferential surface of the rotating rod 305 is rotatably connected to the inner wall of the receiving frame 2, and the bottom of the T-shaped plate 308... The top of the filter screen 306 is in contact with the rotating rod 305, which is rotatably connected to the filter screen 306. The rotating rod 305 is driven to rotate by the motor 304, which in turn drives the stirring plate 307 to rotate. The soybeans that have been poured in are stirred by the stirring plate 307, so that the mud and sand in the soybeans are filtered out by the filter screen 306. This makes the filtered soybeans easier to process, reduces working costs, and improves work efficiency. The rotation of the stirring plate 307 drives the T-shaped plate 308 to rotate. The rotation of the T-shaped plate 308 scrapes off the dust attached to the inner wall of the processing tank 309, preventing the dust from falling back onto the filtered soybeans and enhancing the filtration effect.

[0016] The feeding device 4 includes a guide plate 401, a guide plate 402, a chute 403, a slide plate 404, and a screen frame 406. The guide plate 401 is fixedly connected to the top of the T-shaped plate 308. The screen frame 406 is slidably connected to the inner wall of the receiving frame 2. Rotation of the T-shaped plate 308 drives the guide plate 401 to rotate. When the guide plate 401 rotates, it contacts the guide plate 402, causing the guide plate 402 to move upwards via the guide ramp. The upward movement of the guide plate 402 drives the screen frame 406 to move upwards, which in turn drives the slide plate 404 to move upwards. The upward movement of the slide plate 404 causes the spring telescopic column 405 to extend and retract, causing the screen frame 406 to move up and down reciprocally. This allows the soybeans to be poured into the screen frame 406. The reciprocating movement of the screen frame 406 ensures that the material enters the feed inlet evenly, helping to avoid the accumulation or uneven distribution of agricultural products, thereby improving the efficiency and quality of subsequent processing. Plate 402 is fixedly connected to the bottom of screen frame 406, chute plate 403 is fixedly connected to the inner wall of receiving frame 2, and slide plate 404 is slidably connected to the inner wall of chute plate 403. The feeding device 4 also includes spring telescopic column 405, hinge plate 407, fixed column 408, and hinge plate 409. Spring telescopic column 405 is fixedly connected to the top of slide plate 404, hinge plate 407 is slidably connected to the inner wall of screen frame 406, and fixed column 408 is fixedly connected to hinge plate 409. The top of hinge plate 407 is fixedly connected to the inner wall of fixed column 408. The top of hinge plate 409 is fixedly connected to the bottom of receiving frame 2. The top of spring telescopic column 405 is fixedly connected to the inner wall of slide plate 403. At the same time, when screen frame 406 moves up and down, it will contact hinge plate 407, so that hinge plate 407 opens and closes intermittently when screen frame 406 moves down, so that soybeans are fed evenly and the production efficiency of the machine is improved.

[0017] Working Principle: When the dust suppression and feeding device for agricultural product processing is started, the suction fan inside the suction duct 301 draws the dust generated during the pouring and processing of soybeans into the collection tank 303, effectively reducing the dust generated during the pouring process and preventing it from scattering into the air, thus maintaining environmental hygiene. Simultaneously, the dust generated during the pouring process can affect the health of operators, leading to respiratory problems. The suction duct 301 improves the working environment for workers, ensuring their health and safety. The device is driven by a motor 304 to rotate... Rotating rod 305 drives the stirring plate 307 to rotate, agitating the poured soybeans. This agitates the soybeans, allowing dirt and sand to pass through the filter screen 306, making the filtered soybeans easier to process, reducing labor costs and improving efficiency. The rotation of the stirring plate 307 also drives the T-shaped plate 308 to rotate, scraping off dust adhering to the inner wall of the processing tank 309, preventing dust from falling back onto the filtered soybeans and enhancing the filtration effect.

[0018] The rotation of the T-plate 308 drives the rotation of the guide plate 401. As the guide plate 401 rotates, it pushes the guide plate 402 upwards via an inclined plane. This upward movement of the guide plate 402 drives the screen frame 406 upwards, which in turn drives the slide plate 404 upwards. The slide plate 404 then extends and retracts the spring telescopic column 405, causing the screen frame 406 to move up and down repeatedly. This allows the soybeans to be poured into the screen frame 406. The reciprocating movement of the screen frame 406 ensures that the material enters the feed inlet evenly, preventing accumulation or uneven distribution of the agricultural products, thus improving the efficiency and quality of subsequent processing. Simultaneously, the reciprocating movement of the screen frame 406 contacts the hinge plate 407, causing the hinge plate 407 to open and close intermittently as the screen frame 406 moves downwards, ensuring even feeding of the soybeans and improving the machine's production efficiency.

[0019] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the dust removal device 5 includes a scraper 501, a fixed plate 302, an L-shaped striking plate 503, a rocker 504, a connecting column 505, a hinged plate 306, and a collection box 507. The scraper 501 is fixedly connected to the circumferential surface of the rotating rod 305. When the dust suppression and feeding device for agricultural product processing is started, the rotating rod 305 drives the scraper 501 to rotate. The rotation of the scraper 501 scrapes away the dust filtered from the filter screen 306 in the processing tank 309. When the machine is covered with dust, it needs to be cleaned manually, which reduces work efficiency. The dust removal by the rotation of the scraper 501 can maintain the equipment in the best working condition and improve the machine's work efficiency. The fixed plate 302 is fixedly connected to the bottom of the filter screen 306, and the L-shaped striking plate 503 is hinged to the inner wall of the fixed plate 302 by a torsion spring. The collection box 507 is fixedly connected to the bottom of the processing tank 309. The connecting column 505 is hinged to the inner wall of the collection box 507 by a torsion spring. The rocker plate 504 is fixedly connected to the circumferential surface of the connecting column 505. The hinge plate 506 is fixedly connected to the circumferential surface of the connecting column 505. The outer wall of the hinge plate 506 is in contact with the inner wall of the collection box 507. The bottom of the scraper 501 is in contact with the inner wall of the processing tank 309. When the scraper 501 rotates, it will contact the rocker plate 504, causing the rocker plate 504 to rotate. The rotation of the rocker plate 504 drives the hinge plate 506 to rotate. At the same time, the torsion spring in the connecting rod drives the hinge plate 506 to reset. When the hinge plate 506 rotates, it will open and close intermittently, collecting the dust scraped by the scraper 501 into the collection box 507, making it easier to centrally dump the collected dust and improving the overall working efficiency of the machine.

[0020] Working Principle: When the dust suppression and feeding device for agricultural product processing is started, the rotating rod 305 drives the scraper 501 to rotate. The rotating scraper 501 scrapes the dust filtered from the filter screen 306 onto the processing tank 309. The machine is covered with dust, which requires manual cleaning and reduces work efficiency. The rotation of the scraper 501 removes the dust, keeping the equipment in optimal working condition and improving the machine's efficiency. When the scraper 501 rotates, it contacts the rocker 504, causing the rocker 504 to rotate. The rotation of the rocker 504 drives the hinge plate 506 to rotate, and at the same time, the torsion spring in the connecting rod drives the hinge plate 506 to reset. The rotation of the hinge plate 506 will open and close intermittently, collecting the dust scraped by the scraper 501 into the collection box 507, making it easier to centrally dump the collected dust and improving the overall work efficiency of the machine.
