Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a multifunctional crop seed screening machine. Background Technology

[0002] A seed screening machine uses a vibrating screen with different mesh sizes and shapes to remove impurities (mud clods, sand particles, seeds of other crops, weed seeds, insect galls, husks, etc.), chaff, and small seeds from the seeds, retaining large, plump, and uniform high-quality seeds to improve seed quality. One existing seed screening machine includes a support frame and a screening assembly. An air-separating mechanism is installed above the screening assembly, including an air hood and a collection hood on one side. The air-separating mechanism and the collection hood work together to remove and collect impurities from the seeds.

[0003] During the above process, the hood can blow lighter dust into the collection hood. However, the air blown into the collection hood may cause the collected dust to be stirred up again and carried by the airflow onto the screening components, which will cause the seeds to be contaminated by dust again and reduce the efficiency of dust removal. Therefore, we propose a multi-functional crop seed screening machine. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art where the wind blown into the collection hood causes the collected dust to be re-raised and carried by the airflow onto the screening component, causing the seeds to be contaminated by dust again and reducing the efficiency of dust removal. This invention proposes a multifunctional crop seed screening machine.

[0005] The technical solution of this utility model: A multifunctional crop seed screening machine, including a support frame, on which the screening machine body is fixedly mounted, and further including:

[0006] A cover is fixedly installed above the main body of the screening machine. An air outlet for blowing dust is fixedly installed inside the cover. A collection cover is fixedly installed inside the cover. A dust collection assembly is fixedly installed inside the collection cover. The dust collection assembly includes an axial flow fan fixedly installed on one side of the collection cover.

[0007] The bottom of the collection cover is slidably fitted with a collection box for collecting dust, and a mesh is provided above the collection box to prevent seeds from falling. A push plate is slidably fitted on the top of the mesh.

[0008] Optionally, the screening machine body includes a base, a screening plate is slidably installed in the base, a feed inlet is fixedly installed on the top of the cover, the feed inlet is located between the air outlet and the collection cover, a discharge outlet is provided on one side of the screening machine body, and an inclined plate is fixedly installed on the side of the screen close to the screening plate.

[0009] Optionally, multiple sets of spring telescopic rods are fixedly installed between the bottom of the screening plate and the base, an eccentric wheel is rotatably installed inside the base, the eccentric wheel abuts against the top of the screening plate, and a motor for driving the eccentric wheel to rotate is fixedly installed inside the base.

[0010] Optionally, a blower is fixedly installed on the top of the cover, and a connecting pipe is fixedly connected to the output end of the blower. The air outlet is connected to the connecting pipe. The collecting cover and the air outlet are on the same horizontal line, and the collecting cover is located inside the cover on the side away from the discharge port.

[0011] Optionally, a number of vertically arranged guide plates are fixedly installed on the top of the inner wall of the collection hood. The dust collection assembly also includes a filter element, which is movably installed on the bottom of the hood by a snap-fit. A pipe is fixedly installed at the output end of the axial flow fan, and the other end of the pipe is movably inserted into the bottom of the filter element.

[0012] Optionally, the cover, the collection cover, and the collection box are all provided with through holes for airflow, and a filter screen is fixedly installed in the through holes of the collection box.

The two ends of the push plate are fixedly connected to the sliders respectively, and the bottom of the push plate abuts against the top of the partition.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention uses a dust-collecting component placed at the bottom of the collection hood to suck away the dust inside the collection hood, preventing the dust from being stirred up again by the airflow generated by the air outlet and falling back into the screening machine body, thereby preventing the seeds from being contaminated by dust again and improving the efficiency of dust removal.

[0016] Furthermore, a screen placed above the collection box prevents seeds from entering the collection box, ensuring that only dust is sucked into the collection box. This prevents seeds from being accidentally sucked in during the dust collection process, further guaranteeing the quality of seed screening. At the same time, a pusher plate pushes the seeds on the screen back onto the screening plate, preventing seeds from accumulating on the screen and affecting its normal operation, thus ensuring the continuous and efficient operation of the screening machine.

[0028] Example

[0029] like Figures 1 to 4 As shown, the present invention proposes a multifunctional crop seed screening machine, including a support 1, on which a screening machine body 2 is fixedly installed. The screening machine body 2 includes a base 21, in which a screening plate 4 is slidably installed. A feed inlet 5 is fixedly installed on the top of the cover 3. The feed inlet 5 is located between the air outlet 8 and the collection cover 9. A discharge outlet is provided on one side of the screening machine body 2. An inclined plate 161 is fixedly installed on the side of the partition 16 near the screening plate 4.

[0030] Multiple sets of spring telescopic rods 11 are fixedly installed between the bottom of the screening plate 4 and the base 21. An eccentric wheel 12 is rotatably installed inside the base 21. The eccentric wheel 12 abuts against the top of the screening plate 4. A motor 13 for driving the eccentric wheel 12 to rotate is fixedly installed inside the base 21. By starting the motor 13, the eccentric wheel 12 is driven to rotate, causing the screening plate 4 to vibrate up and down under the support of the spring telescopic rods 11. After the seeds fall onto the vibrating screening plate 4, smaller particles will fall through the sieve holes of the screening plate 4 under the action of vibration, while larger and fuller seeds will remain on the screening plate 4.

[0031] In this embodiment, a cover 3 is fixedly installed above the screening machine body 2, an air outlet 8 for blowing dust is fixedly installed inside the cover 3, a collection cover 9 is fixedly installed inside the cover 3, and a dust collection assembly is fixedly installed inside the collection cover 9. The dust collection assembly includes an axial flow fan 7 fixedly installed on one side of the collection cover 9.

[0032] The blower 6 is fixedly installed on the top of the cover 3. The output end of the blower 6 is fixedly connected to the connecting pipe 61. The air outlet 8 is connected to the connecting pipe 61. The collecting cover 9 is on the same horizontal line as the air outlet 8. The collecting cover 9 is located inside the cover 3 on the side away from the discharge port. When the blower 6 is started, the air outlet 8 blows the airflow toward the falling seeds. Due to the different weights of the seeds and dust, the dust begins to move toward the collecting cover 9 under the action of the wind and enters the collecting cover 9.

[0033] In addition, several sets of vertically arranged guide plates 15 are fixedly installed on the top of the inner wall of the collection hood 9. The guide plates 15 are used to guide the direction of dust and airflow, and improve the smoothness of dust flow to the bottom of the collection hood 9. The dust collection assembly also includes a filter element 17, which is movably installed on the bottom of the hood 3 by a snap-fit. A pipe 10 is fixedly installed at the output end of the axial flow fan 7, and the other end of the pipe 10 is movably inserted into the bottom of the filter element 17. The airflow generated by the axial flow fan 7 enters the pipe 10 and is discharged after being filtered by the filter element 17. When the filter element 17 is blocked or damaged, it can be disassembled and replaced by snap-fit. 3. Both the collection hood 9 and the collection box 14 are provided with through holes for airflow. A filter screen 141 is fixedly installed in the through hole of the collection box 14. The filter screen 141 is used to prevent impurities from leaking out of the collection box 14. When the axial flow fan 7 is started, an upward suction force is generated. The suction force of the axial flow fan 7 draws the dust entering the collection hood 9 to the bottom of the collection hood 9 through the pipe 10 and passes through the partition screen 16 into the collection box 14. This prevents the dust from being re-raised by the airflow generated by the air outlet in the collection hood 9 and falling back into the screening machine body 2, thereby preventing the seeds from being contaminated by dust again and improving the efficiency of dust removal.

[0034] Finally, a collection box 14 for collecting dust is slidably installed at the bottom of the collection cover 9. When a lot of dust accumulates in the collection box 14, the collection box 14 can be slid out from the bottom of the collection cover 9 for cleaning. A mesh 16 is provided above the collection box 14 to prevent seeds from falling. The mesh 16 can block seeds from entering the collection box 14, ensuring that only dust can be sucked into the collection box 14 through the mesh 16.

[0035] In this embodiment, a push plate 18 is slidably installed on the top of the partition 16, and sliding seats 19 are fixedly installed on both sides of the inner wall of the collection cover 9. A lead screw 192 is rotatably installed inside the sliding seat 19, and a motor 191 that drives the lead screw 192 to rotate is fixedly installed on one side of the sliding seat 19. A slider 193 that is threadedly connected to the lead screw 192 is slidably installed inside the sliding seat 19. The two ends of the push plate 18 are fixedly connected to the slider 193 respectively. The bottom of the push plate 18 abuts against the top of the partition 16. When the motor 191 is started, the push plate 18 moves on the partition 16, which realizes that the seeds on the partition 16 are pushed back to the screening plate 4 through the inclined plate 161, preventing the seeds from accumulating and affecting the function of the partition 16, and ensuring the continuous and efficient operation of the screening machine body 2.

[0036] The working principle of this embodiment is as follows: During operation, seeds are first fed into the screening machine body 2 through the feed inlet 5 at the top of the cover 3. At this time, the blower 6 is started, and the airflow generated by the blower 6 enters the air outlet 8 through the connecting pipe 61. The air outlet 8 blows the airflow toward the falling seeds. Due to the weight difference between the seeds and dust, the dust begins to move toward the collection cover 9 under the action of the wind and enters the collection cover 9. The guide plate 15, which is vertically installed inside the collection cover 9, is used to guide the direction of the dust and airflow, improving the smoothness of the dust flowing toward the bottom of the collection cover 9. At the same time, the fixed installation... The axial flow fan 7 installed on one side of the collection hood 9 starts and generates an upward suction force. The suction force of the axial flow fan 7 draws the dust entering the collection hood 9 to the bottom of the collection hood 9 through the pipe 10 and passes through the partition 16 fixedly installed inside the collection hood 9 into the collection box 14. When a lot of dust accumulates in the collection box 14, the collection box 14 can be slid out from the bottom of the collection hood 9 for cleaning. This prevents the dust from being stirred up again by the airflow generated by the air outlet in the collection hood 9 and falling back into the screening machine body 2, thereby preventing the seeds from being contaminated by dust again and improving the efficiency of dust removal.

[0037] The motor 13 inside the base 21 drives the eccentric wheel 12 to rotate. Since the eccentric wheel 12 abuts against the top of the screening plate 4, the screening plate 4 vibrates up and down under the support of the spring telescopic rod 11. After the seeds fall onto the vibrating screening plate 4, under the action of vibration, smaller particles will fall through the sieve holes of the screening plate 4, while larger and fuller seeds will remain on the screening plate 4.

[0038] The motor 191 is started, which causes the lead screw 192, which is rotatably installed in the sliding seat 19, to rotate. This causes the slider 193, which is threadedly connected to the lead screw 192, to slide within the sliding seat 19. This, in turn, causes the push plate 18, which is fixedly installed between the sliders 193, to move on the screen 16. This pushes the seeds on the screen 16 back to the screening plate 4 through the inclined plate 161, preventing the seeds from accumulating and affecting the function of the screen 16, and ensuring the continuous and efficient operation of the screening machine body 2.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
