Description

Technical Field

[0001] This utility model relates to the field of seed processing and screening equipment, and in particular to a vibrating screening device for seed processing. Background Technology

[0002] With the continuous advancement of agricultural modernization, the requirements for seed quality are becoming increasingly stringent. High-quality seeds are the foundation for ensuring high and stable crop yields. However, after harvest, seeds often contain impurities, shriveled seeds, and broken seeds, directly affecting seed purity, germination rate, and sowing quality. Vibration screening devices, as a key piece of equipment in the seed processing process, can effectively remove impurities and substandard particles from seeds through vibration and screening, improving seed quality and commercial value, and meeting the agricultural production demand for high-quality seeds.

[0003] During seed screening, seeds tend to accumulate around the sieve openings, gradually clogging them over time. This reduces the effective screening area, further decreasing screening efficiency. Impurities may become mixed with the seeds, making them difficult to remove effectively, thus lowering seed purity. This can interrupt the screening process, requiring frequent shutdowns for sieve cleaning, shortening equipment lifespan, and increasing maintenance costs. Furthermore, relying solely on vibration during seed screening may result in some lighter impurities remaining in the seeds. Vibration alone may also lead to inaccurate seed grading, resulting in incomplete impurity removal, affecting seed purity, and impacting quality control in subsequent seed processing.

[0015] 1. This utility model, through its vibrating screening mechanism, solves the problem that reduced seed purity leads to interruptions in the screening process, requiring frequent shutdowns for screen cleaning, shortening equipment lifespan, and increasing maintenance costs. The first pulley drives the second pulleys at both ends of the second rotating rod via a belt, causing the second rotating rod to rotate. The eccentric blocks at both ends of the second rotating rod generate centrifugal force during rotation, causing the outer frame to vibrate. This effectively reduces equipment malfunctions caused by seed accumulation or poor flow, ensuring stable equipment operation, lowering maintenance costs, and improving seed purity and quality consistency.

[0016] 2. By incorporating an L-shaped support plate, hydraulic rod, second support rod, first hinge frame, hose, air storage pipe, nozzle, and delivery pipe, the system effectively addresses the problem of incomplete impurity removal, which affects seed purity and subsequent seed processing quality control. When the hydraulic rod extends or retracts, the connecting block at its extension end drives the first hinge frame, causing the support rod to rotate around its connection points with the first and second hinge frames. This, in turn, causes the second support rod to rotate around its connection point with the first support rod. The rotation of the second support rod alters the positions of the connecting ring, hose, connecting pipe, and air storage pipe, effectively improving seed purity, reducing screening times and time costs, and increasing the overall efficiency of the seed processing flow.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 - Figure 4 As shown: a vibrating screening device for seed processing, including a housing 1, with a vibrating screening device 2 installed inside the housing 1;

[0032] The vibrating screening equipment 2 includes: an outer frame 201, two support frames 205, a motor 210, and a second rotating rod 215. The outer side of the outer frame 201 is located inside the housing 1. Connecting columns 202 are fixedly connected to the inside of the left and right side walls of the outer frame 201. The other end of the four connecting columns 202 is fixedly connected to the outer side of the connecting plate 203. Device boxes 204 are fixedly connected to the left and right side walls of the outer frame 201. The device boxes 204 are fixed to the left and right side walls of the outer frame 201 to provide external protection for the internal device. Two support frames 205 are fixedly connected to the left and right side walls inside the housing 1. Both support frames 205 are set on the left and right sides of the outer frame 201. Sleeves 206 are fixedly connected to the bottom walls of the four connecting plates 203 and the top walls of the two support frames 205. Springs 207 are fixedly connected inside each pair of upper and lower sleeves 206. The sleeves 206 on the connecting plates 203 and the support frames 205, as well as the springs 207 inside, play a buffering and stabilizing role, ensuring that the outer frame 201 remains balanced during vibration and providing bottom support for the outer frame 201.

[0033] A filter plate 208 is fixedly connected inside the outer frame 201. After seeds enter the outer frame 201, they fall onto the filter plate 208 and are sieved by the filter plate 208. A support plate 209 is fixedly connected to the top front side of the outer frame 201. A motor 210 is fixedly connected to the top right side of the support plate 209. The support plate 209 is fixed to the top front side of the filter plate 208, thus supporting the bottom of the motor 210 and fixing the motor 210 to the filter plate 208 to drive the device.

[0034] A retainer 211 is fixedly connected to the top left side of the support plate 209. The output end of the motor 210 is fixedly connected to the first rotating rod 212. The middle outer side of the first rotating rod 212 is rotatably connected to the inside of the two retainers 211. The left outer side of the first rotating rod 212 is fixedly connected to the first pulley 213. The first pulley 213 is equipped with a belt 214. After the motor 210 is started, the output end of the motor 210 will drive the first rotating rod 212 to rotate. When the first rotating rod 212 rotates, the middle outer side of the first rotating rod 212 rotates inside the retainer 211. The retainer 211 enables the first rotating rod 212 to operate stably and in a balanced manner. In addition, the left end of the first rotating rod 212 is connected to the first pulley 213 and drives the first pulley 213 to rotate synchronously. The belt 214 is set inside the first pulley 213. After the first pulley 213 is driven, it generates friction with the belt 214 inside, thereby driving the belt 214 to rotate.

[0035] like Figure 1 - Figure 5 As shown, the left and right side walls of the outer frame 201 are rotatably connected to a second rotating rod 215. The left and right ends of the second rotating rod 215 are located inside the device box 204. The outer side of the left end of the second rotating rod 215 is fixedly connected to a second pulley 216. The rear side of the belt 214 is located inside the second pulley 216. The outer sides of the left and right ends of the second rotating rod 215 are fixedly connected to eccentric force blocks 217. The outer sides of the two eccentric force blocks 217 are located inside the device box 204. By moving the first pulley 213 into the interior of the second pulley 216 behind the belt 214, the first pulley 213 drives the second pulleys 216 at both ends of the second rotating rod 215 to rotate through the belt 214, thereby causing the second rotating rod 215 to start rotating. The eccentric force blocks 217 at both ends of the second rotating rod 215 generate centrifugal force during rotation inside the device box 204, causing the outer frame 201 to vibrate.

[0036] like Figure 1 - Figure 10As shown, a bottom box 3 is fixedly connected to the bottom of the box 1. A first guide plate 4 is fixedly connected inside the bottom box 3. A discharge square pipe 5 is connected through the rear side wall of the bottom box 3. Seeds falling through the sieve holes of the filter plate 208 fall into the bottom box 3 at the bottom of the box 1. The first guide plate 4 inside the bottom box 3 guides the seeds to flow towards the discharge square pipe 5 and finally discharges them from the discharge square pipe 5, completing the seed screening and collection work.

[0037] A concave plate 6 is fixedly connected to the inside of the top wall of the housing 1. An inlet 8 is provided on the front side of the concave plate 6. A second guide plate 7 is fixedly connected to the inside of the concave plate 6, located behind the inlet 8. A discharge guide box 9 is fixedly connected to the bottom of the second guide plate 7. Before sieving, seeds are poured into the concave plate 6 and guided by the second guide plate 7, flowing forward and being conveyed through the inlet 8 into the discharge guide box 9. The discharge guide box 9 then conveys the seeds into the housing 1 and precisely onto the filter plate 208. A control panel 10 is fixedly connected to the front wall of the housing 1 for controlling the entire device.

[0038] like Figure 1 - Figure 8 As shown, a fixing plate 11 is fixedly connected to the rear side wall of the box 1. An L-shaped support plate 12 is fixedly connected to the top of the front side wall of the two fixing plates 11. A hydraulic rod 13 is fixedly connected to the front side wall of the two L-shaped support plates 12. The hydraulic rod 13 is fixed to the rear side wall of the box 1 through the fixing plate 11 and to the front side wall of the fixing plate 11 through the L-shaped support plate 12, so as to drive the device at the bottom to operate.

[0039] Two L-shaped support plates 12 and two fixed plates 11 are fixedly connected to the bottom of a first support rod 14. A second support rod 15 is rotatably connected to the outer bottom of each of the two first support rods 14. A connecting block 16 is fixedly connected to the outer bottom of each of the telescopic ends of two hydraulic rods 13. A first hinge frame 17 is fixedly connected to the rear side of each of the two connecting blocks 16. A support rod 18 is rotatably connected inside each of the two first hinge frames 17. A second hinge frame 19 is rotatably connected to the outer bottom of each of the two support rods 18. The bottom walls of the two second hinge frames 19 are fixedly connected to the top of the front side walls of the two second support rods 15. A connecting ring 20 is fixedly connected to the inner front side of each of the two second support rods 15. A flexible hose 21 is fixedly connected to the inner side of each of the two connecting rings 20. The front ends of the two flexible hoses 21 are connected to a connecting pipe 22. The flexible hose 21 is fixed inside the connecting ring 20 inside the front side of the second support rod 15, thereby driving...

[0040] The hose 21 is slid up and down to adjust the angle of the connecting pipe 22 and the gas storage pipe 23.

[0041] The front ends of the two connecting pipes 22 are connected to an air storage pipe 23. The front side walls of the air storage pipe 23 are connected to nozzles 24. The air storage pipe 23 is located on the top of the filter plate 208. When the hydraulic rod 13 extends and retracts, the connecting block 16 on its extension end drives the first hinge frame 17 to move, thereby causing the support rod 18 to rotate around the connection point with the first hinge frame 17 and the second hinge frame 19, thereby driving the second support rod 15 to rotate around the connection point with the first support rod 14.

[0042] The rotation of the second support rod 15 changes the position of the connecting ring 20, hose 21, connecting pipe 22, and air storage pipe 23 connected to it, thereby adjusting the angle and position of the air storage pipe 23 and the nozzle 24. This allows the nozzle 24 to spray air at different angles to clean the surface of the filter plate 208 and the seeds during sieving, effectively removing impurities adhering to the surface of the filter plate 208 and clogging the sieve holes, ensuring continuous and efficient sieving.

[0043] like Figure 1 - Figure 10 As shown, a base plate 26 is fixedly connected to the rear wall of the housing 1. An air pump 27 is installed on the top of the base plate 26. An external pipe 28 is fixedly connected to the input end of the air pump 27, and a delivery pipe 29 is fixedly connected to the output end of the air pump 27. A three-way pipe 25 is connected to the top end of the delivery pipe 29. The left and right ends of the three-way pipe 25 are connected to the rear ends of two hoses 21. By starting the air pump 27 installed on the base plate 26, the air pump 27 draws in outside air through the external pipe 28 and inputs the compressed air into the three-way pipe 25 through the delivery pipe 29. The three-way pipe 25 splits the airflow and delivers it to the connecting pipe 22 through the hoses 21 at the left and right ends, and finally into the air storage pipe 23. The nozzle 24 on the air storage pipe 23 sprays the compressed air onto the surface of the filter plate 208.

[0044] It should be noted that this utility model is a vibrating screening device for seed processing. First, the motor 210, control panel 10, hydraulic rod 13 and air pump 27 are connected to an external power source to supply power to the device.

[0045] The seeds to be screened are poured into the concave plate 6 and guided by the second guide plate 7. The seeds flow along a specific path into the inlet 8 and finally fall into the outlet guide box 9, and then enter the filter plate 208 inside the outer frame 201 from the outlet guide box 9.

[0046] Start the control panel 10 and turn on the motor 210. The motor 210 drives the first rotating rod 212 at the output end to rotate. The middle of the first rotating rod 212 is stably rotated by the retainer 211, and the first pulley 213 at its left end rotates accordingly. The first pulley 213 drives the second pulleys 216 at both ends of the second rotating rod 215 to rotate through the belt 214, thereby causing the second rotating rod 215 to start rotating. The eccentric force blocks 217 at both ends of the second rotating rod 215 generate centrifugal force during rotation, causing the outer frame 201 to vibrate. The left and right sides of the outer frame 201 are connected to the support frame 205 through the connecting column 202 and the connecting plate 203. The sleeve 206 on the connecting plate 203 and the support frame 205, as well as the internal spring 207, play a buffering and stabilizing role, ensuring that the outer frame 201 remains balanced during vibration. Under vibration, the seeds on the filter plate 208 continuously jump and tumble on its surface. Seeds that meet the size requirements of the filter plate 208 sieve holes fall through the sieve holes, while impurities and seeds that do not meet the size requirements remain on the filter plate 208. The impurities and unqualified seeds remaining on the filter plate 208 gradually move towards the waste discharge plate 218 under vibration and are discharged from the housing 1 through the waste discharge plate 218, thus completing the cleaning of impurities.

[0047] Seeds falling through the sieve holes of the filter plate 208 fall into the bottom box 3 at the bottom of the box body 1. The first guide plate 4 inside the bottom box 3 guides the seeds to flow towards the discharge square pipe 5, and finally discharges them from the discharge square pipe 5, completing the seed screening and collection work.

[0048] When it is necessary to clean the filter plate 208 to prevent clogging of the screen holes from affecting the screening efficiency, the air pump 27 installed on the base plate 26 is started. The air pump 27 draws in outside air through the external pipe 28, and after processing, the compressed air is sent into the triple pipe 25 through the delivery pipe 29. The triple pipe 25 splits the airflow, which is delivered to the connecting pipe 22 through the hoses 21 at both ends, and finally enters the air storage pipe 23. The nozzle 24 on the air storage pipe 23 sprays the compressed air onto the surface of the filter plate 208.

[0049] During the air jetting process, the extension and retraction of the hydraulic rod 13 can be controlled via the control panel 10. When the hydraulic rod 13 extends or retracts, the connecting block 16 at its extension end drives the first hinge frame 17 to move, thereby causing the support rod 18 to rotate around its connection point with the first hinge frame 17 and the second hinge frame 19. This, in turn, causes the second support rod 15 to rotate around its connection point with the first support rod 14. The rotation of the second support rod 15 changes the position of the connecting ring 20, hose 21, connecting pipe 22, and air storage pipe 23 connected to it, thus adjusting the angle and position of the air storage pipe 23 and the nozzle 24. In this way, the nozzle 24 can perform air jet cleaning on the filter plate 208 at different angles and positions, effectively removing impurities adhering to the surface of the filter plate 208 and clogging the screen holes, ensuring continuous and efficient screening.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
