Description

Technical Field

[0001] This utility model belongs to the field of gastrodia processing technology, specifically relating to a gastrodia seed screening device. Background Technology

[0002] Gastrodia elata seed screening refers to separating Gastrodia elata seeds according to their different particle sizes using a sieve. Currently, most screening devices for Gastrodia elata can only screen the seeds once. Screening Gastrodia elata of different sizes requires changing the sieve with different aperture sizes, which is not only cumbersome, time-consuming and labor-intensive, but also seriously reduces the screening efficiency of Gastrodia elata, making it difficult to meet the needs of efficient and continuous production. Utility Model Content

[0003] To address the problems of existing Gastrodia elata seed screening devices, which can only screen within a single particle size range and require frequent screen replacements leading to cumbersome operation and low efficiency, this invention provides a Gastrodia elata seed screening device. This device, through a multi-stage screening channel design combined with angle and distance adjustment functions, achieves continuous grading and separation of Gastrodia elata seeds of different sizes without the need for screen replacements, significantly improving screening efficiency and ease of operation.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A Gastrodia elata seed screening device mainly includes a frame, an angle adjustment mechanism, a connecting block, a drive roller, a distance adjustment mechanism, a driven roller, a drive mechanism, a limiting plate, a guide plate, a collection hopper, and a collection box. The angle adjustment mechanism is symmetrically installed at the four corners of the frame. The connecting block is installed on the angle adjustment mechanism. The drive roller is rotatably and inclinedly installed on the connecting block, forming a groove between the connecting blocks. The distance adjustment mechanism is slidably installed inside the groove. The driven roller is rotatably and inclinedly installed on the distance adjustment mechanism. The drive mechanism is installed at the end of the angle adjustment mechanism and is connected to the drive roller for transmission. The gap between the drive roller and the driven roller gradually increases from top to bottom, forming a three-stage grading screening channel. Two limiting plates are installed at the top of the connecting block, directly above the gap between the drive roller and the driven roller. The limiting plates form a V-shaped structure, which can limit the Gastrodia elata seeds and prevent them from overflowing during screening. The guide plate for feeding is installed on the connecting block and extends into the V-shaped structure. Three collection hoppers are installed at the bottom of the connecting block, directly below the gap between the driving and driven rollers. A support plate is provided at the bottom of the frame, and three collection boxes are installed on the support plate, corresponding to the three collection hoppers respectively. The angle adjustment mechanism includes a support plate, a limiting post, and an adjusting plate. The support plate is fixedly installed on the top of the frame and has a strip-shaped through groove. The adjusting plate is installed on the support plate through the limiting post and the strip-shaped through groove. By moving the adjusting plate along the position of the strip-shaped through groove, the tilt angle of the connecting block is changed, thereby adjusting the tilt angle between the driving roller and the driven roller to adapt to the screening requirements of seeds of different particle sizes. The distance adjustment mechanism includes a connecting rod, a slider, and a handwheel. The connecting rod extends through the adjustment plate to the groove between the connecting blocks. The slider is slidably installed in the groove and connected to the connecting rod. The handwheel is installed at the end of the connecting rod. By rotating the handwheel, the connecting rod moves axially, pushing the slider to slide along the groove, thereby changing the distance between the driven roller and the driving roller, and realizing the grading and screening of seeds of different sizes. The drive mechanism includes a connecting plate, a motor, and a belt drive mechanism. The connecting plate is mounted on an adjusting plate, the motor is mounted on the connecting plate, and the drive roller is connected to the output end of the motor via the belt drive mechanism. The motor drives the drive roller to rotate through the belt drive mechanism, completing the seed conveying and sieving. The gap between the driving roller and the driven roller gradually increases from top to bottom, forming a three-stage grading screening channel, corresponding to small, medium, and large-sized Gastrodia elata seeds, respectively. After entering from the guide plate, the seeds pass through each stage of the screening channel in sequence, and seeds of different sizes are separated step by step and fall into the corresponding collection hoppers. The limiting plate adopts an arc-shaped design, and its inner surface is provided with a smooth coating to reduce the frictional resistance of seeds when entering the screening channel, while guiding the seeds to be evenly distributed between the active roller and the driven roller, ensuring the stability and uniformity of the screening process. The guide plate is installed at an angle on the connecting block, and the bottom end of the guide plate extends into the V-shaped structure formed by the limiting plate, ensuring that the seeds can accurately enter the screening channel between the active roller and the driven roller. The collecting hopper features a funnel-shaped design, with its bottom outlet corresponding to the collection box, ensuring that the separated seeds can fall smoothly into the collection box. A buffer layer is installed on the inner wall of the collecting hopper to reduce impact damage to the seeds during their descent. The collection box can be slidably mounted on the support plate for easy disassembly and cleaning. This invention utilizes a multi-stage sieving channel design, combined with angle and distance adjustment functions, to achieve continuous grading and separation of Gastrodia elata seeds of different sizes. It can meet the sieving needs of various particle size ranges without requiring screen replacement. The angle adjustment mechanism optimizes seed flowability and sieving effect by adjusting the inclination angle between the active and driven rollers; the distance adjustment mechanism precisely controls the sieving particle size range by adjusting the distance between the active and driven rollers. The beneficial effects of this utility model are: The angle adjustment mechanism allows for flexible adjustment of the tilt angles of the drive and driven rollers according to actual needs, thereby altering the trajectory and speed of the Gastrodia elata seeds during the screening process and improving screening efficiency and accuracy. The distance adjustment mechanism allows for adjustment of the gap between the drive and driven rollers based on the size of the Gastrodia elata seeds, enabling screening of seeds of different sizes without the need to replace the screen. This simple and convenient operation saves time and labor costs. The gap between the drive and driven rollers gradually increases from top to bottom, and three collection hoppers and corresponding collection boxes are located directly below the gap, enabling multi-stage screening of the Gastrodia elata seeds and collecting seeds of different sizes separately to meet diverse production needs.

[0010] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0011] This utility model discloses a gastrodia elata seed screening device, such as Figure 1As shown, the Gastrodia elata seed screening device mainly includes a frame 1, an angle adjustment mechanism 2, a connecting block 3, a driving roller 4, a distance adjustment mechanism 5, a driven roller 6, a driving mechanism 7, a limiting plate 8, a guide plate 9, a collecting hopper 10, and a collecting box 11. The frame 1 is the main supporting body of the entire device, and the angle adjustment mechanism 2 is fixedly installed at its top. The angle adjustment mechanism 2 consists of a support plate 12, a limiting post 18, and an adjusting plate 19. The support plate 12 is fixed to the top of the frame 1 and has a strip-shaped through groove. The adjusting plate 19 is installed on the support plate 12 through the limiting post 18 and the strip-shaped through groove. The adjusting plate 19 can move along the strip-shaped through groove, thereby changing the tilt angle of the connecting block 3. The connecting block 3 is installed on the angle adjustment mechanism 2, and a sliding groove is formed inside it to accommodate the distance adjustment mechanism 5. The connecting block 3 also serves to fix the driving roller 4 and the driven roller 6. The driving roller 4 is rotatably and tiltedly mounted on the connecting block 3, while the driven roller 6 is mounted in the chute via the distance adjustment mechanism 5 and is also tilted. The gap between the driving roller 4 and the driven roller 6 gradually increases from top to bottom, forming a three-stage grading and screening channel, corresponding to small, medium, and large-sized Gastrodia elata seeds, respectively.

[0012] like Figure 2 , Figure 3 As shown, the distance adjustment mechanism 5 consists of a connecting rod 13, a slider 14, and a handwheel 15. The connecting rod 13 extends through the adjusting plate 19 to the slide groove. The slider 14 is slidably installed in the slide groove and connected to the connecting rod 13. The handwheel 15 is installed at the end of the connecting rod 13. When the handwheel 15 is rotated, the connecting rod 13 moves axially, pushing the slider 14 to slide along the slide groove, thereby changing the distance between the driven roller 6 and the driving roller 4. This design allows the device to adapt to the seed screening needs of different particle size ranges and achieve continuous grading and separation without changing the screen.

[0013] like Figure 2 , Figure 3 , Figure 4 As shown, the drive mechanism 7 includes a connecting plate 20, a motor 16, and a belt drive mechanism 17. The connecting plate 20 is mounted on the adjusting plate 19, and the motor 16 is fixed on the connecting plate 20. Its output end is connected to the drive roller 4 through the belt drive mechanism 17. When the motor 16 starts, it drives the drive roller 4 to rotate through the belt drive mechanism 17. The seeds roll in the gap between the drive roller 4 and the driven roller 6. As the gap gradually increases from top to bottom, seeds of different sizes are separated step by step and fall into the corresponding collection hopper 10.

[0014] like Figure 4As shown, the limiting plate 8 is installed at the top of the connecting block 3, directly above the gap between the driving roller 4 and the driven roller 6. A V-shaped structure is formed between the two limiting plates 8, and its inner surface is coated with a smooth coating to reduce frictional resistance when seeds enter the screening channel. The guide plate 9 is installed obliquely on the connecting block 3, with its bottom end extending into the V-shaped structure formed by the limiting plates 8. The design of the guide plate 9 ensures that seeds can accurately enter the screening channel between the driving roller 4 and the driven roller 6, while preventing seeds from overflowing during the feeding process.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the collecting hopper 10 is installed at the bottom of the connecting block 3, directly below the gap between the driving roller 4 and the driven roller 6. The collecting hopper 10 adopts a funnel-shaped design, with its bottom outlet corresponding to the collecting box 11, ensuring that the separated seeds can fall smoothly into the collecting box 11. The inner wall of the collecting hopper 10 is provided with a buffer layer to reduce impact damage to the seeds during the falling process. The collecting box 11 is slidably mounted on the support plate 12 for easy disassembly and cleaning.

[0016] In actual operation, the parameters of the angle adjustment mechanism 2 and the distance adjustment mechanism 5 are first adjusted according to the particle size range of the seeds to be screened. By moving the adjustment plate 19 along the strip groove, the tilt angle of the connecting block 3 is changed, thereby adjusting the tilt angle between the active roller 4 and the driven roller 6. Then, the handwheel 15 is rotated to push the slider 14 to slide along the chute, adjusting the distance between the driven roller 6 and the active roller 4. After the parameter adjustment is completed, the Gastrodia elata seeds to be screened are poured into the guide plate 9. The seeds enter the V-shaped structure formed by the limiting plate 8 through the guide plate 9 and are evenly distributed between the active roller 4 and the driven roller 6. After starting the motor 16, the active roller 4 rotates through the belt drive mechanism 17, and the seeds roll in the gap between the active roller 4 and the driven roller 6, passing through the three-stage screening channel in sequence. Small-sized seeds fall first from the uppermost gap and enter the corresponding collection hopper 10; medium-sized seeds then fall from the middle gap and enter the corresponding collection hopper 10; large-sized seeds finally fall from the lowermost gap and enter the corresponding collection hopper 10. After separation, the seeds fall into the collection box 11 through the collection hopper 10, completing the sieving process. This device, through the cooperation of the angle adjustment mechanism 2 and the distance adjustment mechanism 5, achieves continuous grading and separation of Gastrodia elata seeds of different sizes, eliminating the need for frequent screen replacements and significantly improving sieving efficiency and ease of operation.

[0017] Work process: First, the operator adjusts the parameters of the angle adjustment mechanism 2 according to the particle size range of the Gastrodia elata seeds to be screened. By moving the adjustment plate 19 along the strip groove on the support plate 12, the tilt angle of the connecting block 3 is changed, thereby adjusting the inclination angle between the driving roller 4 and the driven roller 6. This adjustment ensures that the seeds are distributed at the optimal angle when entering the screening channel, improving screening efficiency. Subsequently, rotating the handwheel 15 moves the connecting rod 13 axially, pushing the slider 14 to slide along the chute, thereby changing the distance between the driven roller 6 and the driving roller 4. This distance adjustment allows the device to adapt to the screening needs of seeds with different particle size ranges, achieving continuous grading and separation without changing the screen.

[0018] After adjusting the above parameters, pour the Gastrodia elata seeds to be screened into the guide plate 9. This device can also be connected to a conveying device for continuous screening. The guide plate 9 is installed at an angle on the connecting block 3, with its bottom extending into the V-shaped structure formed by the limiting plate 8. The seeds are guided by the guide plate 9 into the space between the limiting plates 8 and evenly distributed in the screening channel between the driving roller 4 and the driven roller 6. The limiting plate 8 adopts an arc-shaped design, and its inner surface is coated with a smooth coating, effectively reducing the frictional resistance when the seeds enter the screening channel, while guiding the seeds to distribute evenly and preventing accumulation or overflow.

[0019] After starting motor 16, motor 16 drives the drive roller 4 to rotate via belt drive mechanism 17. Seeds roll in the gap between drive roller 4 and driven roller 6. As the gap gradually increases from top to bottom, seeds of different sizes are separated step by step. Smaller seeds fall first from the top gap and enter the corresponding collection hopper 10; medium-sized seeds then fall from the middle gap and enter the corresponding collection hopper 10; large-sized seeds finally fall from the bottom gap and enter the corresponding collection hopper 10. The collection hopper 10 adopts a funnel-shaped design, with its bottom outlet corresponding to the collection box 11, ensuring that the separated seeds can fall smoothly into the collection box 11. The inner wall of the collection hopper 10 is provided with a buffer layer to reduce impact damage to the seeds during the falling process.

[0020] The separated seeds fall into the collection box 11 through the collecting hopper 10, completing the screening process. The collection box 11 is slidably mounted on the support plate 12 for easy disassembly and cleaning. The entire device has a compact structure, is suitable for efficient and continuous production environments, and can meet the screening requirements of various particle size ranges.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
