Description

Technical Field

[0001] This utility model relates to the field of seed equipment technology, specifically a gourd seed air separator. Background Technology

[0002] Gourd seeds are typically obtained in autumn. After harvesting mature gourds, they are crushed, and the seeds are removed by washing. The seeds are then dried. Finally, the dried gourd seeds are winnowed to remove impurities such as gourd pulp and pebbles.

[0003] A search revealed a wind-separation seed selection and processing device (publication number CN221657177U) comprising a wind-separation box with a feed hopper connected to the top, a discharge pipe connected to the right side, a collection box slidably connected inside, and a discharge pipe connected to the left side, extending into the interior of the wind-separation box. A C-shaped plate is fixedly connected to the left side of the wind-separation box. The seeds entering the wind-separation box are sorted by a wind-separating fan, thus initially screening out impurities such as leaves mixed in with the seeds, and simultaneously discharging the impurities through the discharge pipe. A connecting rod, driven by the rotation of an eccentric disc, causes the screen plate to vibrate, and with the cooperation of four elastic plates, the screen plate automatically resets, thereby vibrating and screening the seeds on the screen plate, further removing particles and stones from the seeds and separating unqualified small seeds, improving the seed selection process.

[0004] However, the hopper of the aforementioned wind-selection seed cleaning and processing equipment cannot control the quantitative and uniform falling of the seeds to be cleaned, which will affect the seed cleaning effect. Utility Model Content

[0005] This invention provides a solution to the problem mentioned in the background art that the hopper of the wind-selection seed refining equipment cannot control the quantitative and uniform falling of the seeds to be cleaned, which affects the seed refining effect.

[0006] To address the existing problems, this utility model provides a gourd seed wind separator, including a frame, a support arm fixedly connected to the lower part of one end of the frame, a feeding mechanism provided inside the frame, and a grading and screening mechanism provided at the lower part of the other end of the frame.

[0007] The feeding mechanism includes several rotating rollers rotatably connected to the inner side of the frame. A conveyor belt is sleeved on the outer side of each rotating roller. Push plates are evenly spaced on the surface of the conveyor belt. One end of the rotating roller located at one end of the conveyor belt passes through the side wall of the frame and is fixedly connected to the output shaft of the drive motor. The drive motor is fixedly connected to the outer wall of the frame. A limiting trough is fixedly connected to the upper part of the conveyor belt and at the upper end of the frame. A roller brush is provided on the side of the limiting trough near the grading and screening mechanism. Both ends of the roller brush are rotatably connected to the frame. The roller brush is located on the upper side of the conveyor belt. The lowermost end of the roller brush is pressed against the upper surface of the push plate. One end of the roller brush passes through the side wall of the frame and is fixedly connected to a first gear. The first gear meshes with a second gear rotatably mounted on the outer wall of the frame. One end of the rotating roller located at the other end of the conveyor belt passes through the side wall of the frame and is fixedly connected to a drive sprocket. The drive sprocket is driven by a driven sprocket coaxially connected to the second gear via a chain.

[0008] Furthermore, the grading and screening mechanism includes a frame plate fixedly connected to the lower end of the frame. A baffle is fixedly connected to one end of the frame plate near the support arm. A primary screen plate and a secondary screen plate are fixedly connected to the inner side of the frame plate from top to bottom. A slag discharge pipe and a material discharge pipe are respectively connected to the ends of the primary screen plate and the secondary screen plate away from the baffle. A fan is installed on the upper side of the primary screen plate and on the baffle.

[0009] Furthermore, a slag inlet is provided on the upper side of the slag discharge pipe, and the lower end of the slag inlet is fixedly connected to the end of the primary screen plate. A feed inlet is provided on the side of the discharge pipe, and the end of the secondary screen plate is fixedly connected to the lower end of the feed inlet.

[0010] Furthermore, a 5cm gap is provided between the lower end of the limiting material groove near the roller brush and the push plate, and a rubber layer is provided at the lower end of the limiting material groove away from the roller brush, with the lower end of the rubber layer sliding in contact with the upper surface of the push plate.

[0011] Furthermore, a cover plate is fixedly connected above the grading and screening mechanism and at the upper end of the frame, and a camera is installed above the cover plate.

[0012] Furthermore, the drive motor, fan, and camera are all electrically connected to the PLC controller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This gourd seed air separator, through its feeding mechanism, uses a rotating roller brush to reverse-sort gourd seeds on the conveyor belt that exceed the height of the push plate during operation. After being treated by the roller brush, the gourd seeds on the conveyor belt surface are uniformly flat and flush with the upper surface of the push plate. As the conveyor belt continues to run, the gourd seeds fall evenly from the end of the conveyor belt into the grading and screening mechanism. This process ensures that the number of gourd seeds falling into the grading and screening mechanism per unit time is constant and evenly distributed, overcoming the shortcomings of existing technologies and thus improving the air-separation quality of gourd seeds. In addition, the grading and screening mechanism can perform two fine screenings on the gourd seeds, effectively removing impurities with the assistance of the blower, resulting in excellent impurity removal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A gourd seed wind separator includes a frame 1, a support arm 2 fixedly connected to the lower part of one end of the frame 1, a feeding mechanism 3 provided on the inner side of the frame 1, and a grading and screening mechanism 4 provided at the lower part of the other end of the frame 1.

[0023] The feeding mechanism 3 includes several rotating rollers 301 rotatably connected to the inner side of the frame 1. A conveyor belt 302 is sleeved on the outer side of the rotating rollers 301. Push plates 303 are evenly spaced on the surface of the conveyor belt 302. One end of the rotating roller 301 located at one end of the conveyor belt 302 passes through the side wall of the frame 1 and is fixedly connected to the output shaft of the drive motor 304. The drive motor 304 is fixedly connected to the outer wall of the frame 1. A limiting trough 305 is fixedly connected above the conveyor belt 302 and at the upper end of the frame 1. A roller brush 306 is provided on the side of the limiting trough 305 near the grading and screening mechanism 4. The two ends of the roller 306 are rotatably connected to the frame 1. The roller brush 306 is located on the upper side of the conveyor belt 302. The lowest end of the roller brush 306 is pressed and contacted with the upper surface of the push plate 303. One end of the roller brush 306 passes through the side wall of the frame 1 and is fixedly connected to the first gear 307. The first gear 307 meshes with the second gear 308 rotatably mounted on the outer wall of the frame 1. The roller 301 located at the other end of the conveyor belt 302 passes through the side wall of the frame 1 and is fixedly connected to the drive sprocket 309. The drive sprocket 309 is driven by the driven sprocket 311, which is coaxially connected to the second gear 308 through the chain 310.

[0024] It should be noted that the surface of the roller brush 306 is covered with bristles. When the roller brush 306 rotates, its lowest point comes into contact with the upper surface of the push plate 303. This contact causes the bristles to deform, thus effectively brushing the gourd seeds. At the same time, due to the deformation of the bristles, the roller brush 306 does not obstruct the movement of the push plate 303, thereby ensuring that the push plate 303 can move smoothly with the conveyor belt 302. Furthermore, the bristles can be made of nylon, polypropylene, or carbon fiber reinforced plastic, but are not limited to these materials.

[0025] The grading and screening mechanism 4 includes a frame plate 401 fixedly connected to the lower end of the frame 1. A baffle 402 is fixedly connected to one end of the frame plate 401 near the support arm 2. A primary screen plate 403 and a secondary screen plate 404 are fixedly connected to the inner side of the frame plate 401 from top to bottom. A slag discharge pipe 405 and a material discharge pipe 406 are respectively connected to the ends of the primary screen plate 403 and the secondary screen plate 404 away from the baffle 402. A blower 407 is installed on the upper side of the primary screen plate 403 and on the baffle 402.

[0026] The slag discharge pipe 405 has a slag inlet 4051 on the upper side, and the lower end of the slag inlet 4051 is fixedly connected to the end of the primary screen plate 403. The discharge pipe 406 has a feed inlet 4061 on the side, and the end of the secondary screen plate 404 is fixedly connected to the lower end of the feed inlet 4061.

[0027] Among them, the lower end of the limiting material groove 305 near the roller brush 306 is provided with a 5cm gap between it and the push plate 303, and the lower end of the limiting material groove 305 away from the roller brush 306 is provided with a rubber layer, and the lower end of the rubber layer slides in contact with the upper surface of the push plate 303.

[0028] Among them, a cover plate 5 is fixedly connected above the grading and screening mechanism 4 and at the upper end of the frame 1, and a camera 6 is installed on the cover plate 5.

[0029] Among them, the drive motor 304, the fan 407, and the camera 6 are all electrically connected to the PLC controller 7.

[0030] Working principle: First, the gourd seeds to be air-separated are conveyed to the limiting trough 305 by the feeding equipment. Then, the air separator is started by the PLC controller 7. At this time, the drive motor 304 drives the rotating roller 301 fixedly connected to its output shaft to rotate. The rotating roller 301 then drives the conveyor belt 302 to rotate on other rotating rollers 301. At the same time, a rotating roller 301 located at the end of the conveyor belt 302 drives the drive sprocket 309 to rotate. The rotating drive sprocket 309 drives the driven sprocket 311 to rotate through the chain 310. The rotating driven sprocket 311 then drives the second gear 308 fixedly connected to it to rotate. The rotation of the second gear 308 then drives the first gear 307 meshed with it to rotate. The first gear 307 then drives the roller brush 306 fixedly connected to it to rotate. The bristles on the surface of the rotating roller brush 306 brush the gourd seeds on the surface of the conveyor belt 302 that are higher than the push plate 303 to rotate. In the opposite direction of the conveyor belt 302's travel, the gourd seeds on the conveyor surface are evenly spread out and flush with the upper surface of the push plate 303. As the conveyor belt 302 continues to run, the gourd seeds will fall from the end of the conveyor onto the primary screen plate 403. During the process of the gourd seeds falling onto the primary screen plate 403, the blower 407 will blow away the light fragments and other debris mixed in with the gourd seeds, while heavier particles such as stones will slide off the primary screen plate 403 into the slag discharge pipe. The slag inlet 4051 of 405 discharges the slag from the bottom of the slag discharge pipe 405. The gourd seeds and some heavier small particles fall from the screen holes of the primary screen plate 403 to the secondary screen plate 404. The heavier small particles fall from the screen holes of the secondary screen plate 404 to the ground, while the gourd seeds slide down the surface of the secondary screen plate 404 and enter through the feed inlet 4061 of the discharge pipe 4061, falling from the bottom of the discharge pipe 406 into the pre-placed collection container.

[0031] Secondly, the monitoring screen of camera 6 can be viewed on the PLC controller screen at regular intervals to check the remaining amount of gourd seeds in the limiting trough 305, so that the gourd seeds to be cleaned can be put into the limiting trough 305 in a timely manner. At the same time, the operation of the conveyor belt 302 of the feeding mechanism 3 can be viewed through the camera so that problems can be dealt with in a timely manner.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
