Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a spiral screening machine for zucchini seeds. Background Technology

[0002] The core principle of a spiral sorting machine in sorting zucchini seeds is to utilize the difference in pitch between the large and small spiral blades. As the seeds rotate and fall, the difference in centrifugal force due to their different masses separates them. Larger, plump seeds, with stronger centrifugal force, enter the channel of the large spiral blade; smaller, shriveled seeds are discharged along the channel inside the small spiral blade.

[0003] However, this traditional screening method usually relies on manual labor to lift the seeds by hand for feeding, which is not only labor-intensive but also cannot achieve continuous production, severely restricting production efficiency. Zucchini seeds are light and have a flat structure, so centrifugal force alone is not effective in separating them, resulting in inconsistent seed quality. At the same time, the seeds are also very easy to accumulate and clog in the hopper, requiring workers to frequently stop the machine to clean them, further exacerbating production interruptions.

[0004] Therefore, it is necessary to provide a spiral screening machine for zucchini seeds to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the aforementioned problems, this application provides a spiral screening machine for zucchini seeds, which solves the problems in the prior art mentioned in the background section, such as poor centrifugal separation effect, easy accumulation and blockage in the hopper, frequent production interruptions, high labor intensity of manual feeding, and inability to achieve continuous production due to the light weight and flat shape of zucchini seeds.

[0006] To achieve the objectives of this application, the following technical solution is provided:

[0007] This application provides a spiral screening machine for zucchini seeds, including a large spiral blade and a small spiral blade nested coaxially. A support is fixedly installed on the outer wall of the large spiral blade. A collection hopper and a conical hopper are installed sequentially from bottom to top on the inner side of the support. The collection hopper is located at the top of the small spiral blade. A vibrating base is fixedly installed at the bottom of the support. The vibrating base includes a support seat and a fixed seat. The support seat is fixedly connected to the lower end of the support and is located at the upper end of the fixed seat. The two are connected by multiple sets of elastic rods. A vibrating motor is detachably installed at the center of the support seat.

[0008] In one possible implementation, the elastic rod includes an outer tube and an inner rod, the inner rod being movably sleeved on the inner wall of the outer tube, and a spring being movably sleeved on the outer wall of the inner rod, the spring being located on the upper outer surface of the outer tube.

[0009] In one possible implementation, the inner wall of the outer tube is provided with a sliding groove, and a locking block is fixedly installed on the outer wall of the inner rod, wherein the locking block and the sliding groove are slidably connected.

[0010] In one possible implementation, a suction device is installed at the upper end of the conical hopper.

[0011] In one possible implementation, a rotating rod is rotatably mounted on the inner side of the conical hopper, the top end of the rotating rod is connected to a drive motor, and a stirring rod and a spiral blade are fixedly mounted on the outer wall of the rotating rod.

[0012] In one possible implementation, the lower end of the conical hopper is fixedly connected to a conveying pipe, and the spiral blade is located on the inner wall of the conveying pipe.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model enhances the vibration force of the equipment by setting a vibration motor and elastic rod. This effectively compensates for the problem that the separation effect of zucchini seeds is poor due to their light weight, flat shape and small centrifugal force. It enables the seeds to be separated more fully during the screening process, improves the accuracy and efficiency of screening, and ensures that plump seeds are effectively distinguished from shriveled seeds.

[0015] 2. This utility model achieves an anti-clogging effect through the rotating rod, stirring rod, and spiral blade set inside the conical hopper. The drive motor drives them to rotate, the stirring rod prevents seeds from accumulating and clogging, and the spiral blade guides the seeds to be output in an orderly manner, ensuring smooth feeding of the screening machine, reducing the occurrence of failures, and improving the stability of equipment operation.

[0016] 3. This utility model achieves automatic feeding through a suction device installed at the top of the conical hopper. This device avoids the inconvenience and safety risks of manual climbing to high places to feed materials, reduces labor intensity, and at the same time greatly improves feeding efficiency, ensures the continuity of screening work, and makes the production process more efficient and convenient.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means three or more.

[0026] Figures 1-5A spiral sorting machine for zucchini seeds provided in this application embodiment includes a large spiral blade 1 and a small spiral blade 2 coaxially nested. A support 3 is fixedly installed on the outer wall of the large spiral blade 1. A collection hopper 4 and a conical hopper 5 are installed sequentially from bottom to top on the inner side of the support 3. The collection hopper 4 is located at the top of the small spiral blade 2. A vibrating base 6 is fixedly installed at the bottom of the support 3. The vibrating base 6 includes a support seat 7 and a fixed seat 8. The support seat 7 is fixedly connected to the lower end of the support 3. The support seat 7 is located at the upper end of the fixed seat 8, and the two are connected by multiple sets of elastic rods 9. A vibration motor 10 is detachably installed at the center of the support seat 7. The sorting machine uses centrifugal force and vibration to sort zucchini seeds. Seeds enter the channel of the small spiral blade 2 from the conical hopper 5 through the collection hopper 4. The narrow pitch of the small spiral blade 2 causes the seeds to rotate and fall, generating centrifugal force. Seeds with large mass break through the constraint of the small spiral due to strong centrifugal force and enter the channel of the large spiral blade 1, while seeds with small mass continue to be transported in the small spiral. The vibrating motor 10 is mounted on the support base 7 and generates vibration during operation. The vibration is transmitted to the entire device via the support base 7 and the fixed base 8 connected by the elastic rod 9. The elasticity of the elastic rod 9 enhances the vibration force, effectively overcoming the problems of light weight and low centrifugal force in zucchini seeds, thus promoting better seed separation. Vibration breaks up seed agglomeration caused by static electricity, humidity, and other factors, allowing seeds to separate and participate in sorting as individual particles. Furthermore, vibration makes the seeds move more actively on the spiral blades, accelerating the separation of seeds of different weights and improving sorting efficiency. The conical structure at the bottom of the collecting hopper 4 guides the seeds to fall precisely into the small spiral blades 2, ensuring the smooth progress of the screening process. Finally, plump seeds are discharged from the bottom outlet through the large spiral blade 1, while shriveled seeds are discharged from the bottom light material outlet along the channel inside the small spiral blades 2.

[0027] In one possible implementation, the elastic rod 9 includes an outer tube 11 and an inner rod 12. The inner rod 12 is movably sleeved on the inner wall of the outer tube 11, and a spring 13 is movably sleeved on the outer wall of the inner rod 12, located on the upper outer surface of the outer tube 11. The elastic rod 9, composed of the outer tube 11, the inner rod 12, and the spring 13, serves to achieve an elastic connection between the support base 7 and the fixed base 8, and to enhance the vibration effect of the equipment. The inner rod 12 can extend and retract up and down on the inner wall of the outer tube 11, and the spring 13 is sleeved on the outer wall of the inner rod 12 and located on the upper outer surface of the outer tube 11. When the vibration motor 10 operates, the support base 7 is displaced by vibration, the inner rod 12 extends and retracts within the outer tube 11, and the spring 13 is compressed or extended accordingly. The elastic restoring force of the spring 13 further enhances the vibration transmission effect, making the vibration of the entire screening machine more stable and powerful, thereby improving the seed screening efficiency and separation effect.

[0028] In one possible implementation, the inner wall of the outer tube 11 is provided with a groove 15, and a locking block 14 is fixedly installed on the outer wall of the inner rod 12, with the locking block 14 slidably connected to the groove 15. The sliding connection between the groove 15 on the inner wall of the outer tube 11 and the locking block 14 on the outer wall of the inner rod 12 is mainly to ensure the stability and safety of the movement of the inner rod 12 within the outer tube 11. When the elastic rod 9 is subjected to force and expands or contracts during vibration, the locking block 14 slides along the groove 15, restricting the inner rod 12 to move only in the vertical direction, preventing radial offset or rotation, and ensuring smooth expansion and contraction of the elastic rod 9. At the same time, since the groove 15 ends near the opening of the outer tube 11, when the inner rod 12 moves to its limit position, the locking block 14 will be blocked by the end of the groove 15, preventing the inner rod 12 from falling off the inner wall of the outer tube 11, ensuring the integrity and reliability of the elastic rod 9 structure, and thus maintaining the normal operation of the screening machine vibration system.

[0029] In one possible implementation method, such as Figure 1 and Figure 5 As shown, a suction device 16 is installed at the upper end of the conical hopper 5. The suction device 16 consists of a material pipe and a blower, mainly solving the problem of inconvenience in manual feeding caused by the height of the screening machine. When the blower is working, it generates suction, which draws the zucchini seeds from the lower part of the material pipe and transports them to the upper conical hopper 5. In actual operation, the seeds to be screened only need to be placed near the inlet of the material pipe. After the blower is started, the strong suction will cause the seeds to move quickly in the material pipe and eventually enter the conical hopper 5 smoothly. This feeding method eliminates the need for manual climbing to the upper part of the screening machine, which not only reduces labor intensity and improves work efficiency, but also avoids the safety risks that may occur during manual feeding, realizing the automation and convenience of zucchini seed feeding.

[0030] In one possible implementation, a rotating rod 17 is rotatably mounted on the inner side of the conical hopper 5. The top of the rotating rod 17 is connected to a drive motor 18, and a stirring rod 19 and a spiral blade 20 are fixedly mounted on the outer wall of the rotating rod 17. The drive motor 18, through its fixed connection with the rotating rod 17, drives the rotating rod 17 to rotate within the conical hopper 5, thereby causing the stirring rod 19 and spiral blade 20 on the outer wall of the rotating rod 17 to rotate together. When the stirring rod 19 rotates inside the conical hopper 5, it stirs the accumulated zucchini seeds, breaking up the mutual compression and adhesion between the seeds by continuously turning and pushing them, preventing the seeds from clogging within the conical hopper 5, and ensuring that the seeds can flow smoothly downwards. At the same time, the spiral blade 20 also rotates with the rotating rod 17. Its spiral structure guides the seeds to move orderly towards the lower end of the conical hopper 5, preparing the seeds for entry into the conveying pipe 21, ensuring the continuity and stability of the feeding process of the screening machine.

[0031] In one possible implementation, the lower end of the conical hopper 5 is fixedly connected to a conveying pipe 21, and the spiral blade 20 is located on the inner wall of the conveying pipe 21. The spiral blade 20, located on the inner wall of the conveying pipe 21 and connected to the rotating rod 17, causes the spiral blade 20 to rotate within the conveying pipe 21 when the drive motor 18 drives the rotating rod 17 to rotate. Utilizing the spiral propulsion principle, the seeds in the conical hopper 5 are pushed downwards along the conveying pipe 21. By controlling the rotational speed of the drive motor 18, the rotational speed of the spiral blade 20 can be changed, thereby adjusting the seed conveying speed within the conveying pipe 21 to meet different screening operation requirements. When it is necessary to pause the screening operation, the drive motor 18 is turned off, the spiral blade 20 stops rotating, and the seed conveying also stops, achieving precise control of the seed conveying process and ensuring the flexibility and controllability of the screening machine operation.

[0032] Working principle:

[0033] When the zucchini seed spiral sorting machine is working, the suction device 16 is activated first. Its drive structure generates suction, drawing the seeds to be sorted from a low position through the feed pipe and conveying them to the conical hopper 5, solving the problem of inconvenient manual feeding. Next, the seeds fall from the conical hopper 5 to the collecting hopper 4. The conical structure at the bottom of the collecting hopper 4 guides the seeds precisely into the channel of the small spiral blade 2. The small spiral blade 2 has a narrow pitch design, generating centrifugal force during the seed's rotation and descent. At this time, the vibration motor 10 starts working, and the vibration it generates is transmitted to the entire equipment through the support seat 7 and the elastic rod 9. The spring 13 inside the elastic rod 9 extends and retracts to enhance the vibration force, compensating for the poor separation effect caused by the light weight and low centrifugal force of zucchini seeds. Under the combined action of centrifugal force and vibration, the heavier, plump seeds break through the constraint of the small spiral blade 2 and enter the channel of the large spiral blade 1. Because the large spiral blade 1 has a wide pitch and a high outer edge, it conveys them downwards to the dedicated discharge port; the lighter, shriveled seeds continue to slide down the inner channel of the small spiral blade 2 and are discharged from the independent light material outlet. In addition, when the seeds are in the conical hopper 5, the drive motor 18 drives the rotating rod 17 to rotate, which causes the stirring rod 19 to stir the seeds and prevent blockage. At the same time, the spiral blade 20 rotates to guide the seeds into the conveying pipe 21 in an orderly manner. By controlling the speed of the drive motor 18, the seed conveying speed and start / stop can be precisely adjusted to ensure the efficient and stable operation of the screening process.

This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
