Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening technology for Prunella vulgaris fruit spikes and seeds, and in particular to a screening device for Prunella vulgaris fruit spikes and seeds. Background Technology
[0002] Prunella vulgaris is a plant with high medicinal value, and its fruit spikes, once mature, can be used to extract seeds. These seeds can be used to propagate new Prunella vulgaris plants. The seed selection process needs to be careful to ensure the quality and purity of the seeds.
[0003] During the screening process, various tools, such as sieves and vibrating screens, may be used to help separate the seeds. The screened seeds can then undergo further processing, such as washing and drying, to improve their germination rate and shelf life. However, existing screening equipment only uses simple vibration for screening, which, while feasible, is inefficient.
[0004] Therefore, it is necessary to provide a seed screening device for Prunella vulgaris spikelets to solve the above-mentioned technical problems. Utility Model Content
[0005] This invention provides a seed sieving device for Prunella vulgaris spikelets, which solves the problems in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a seed sieving device for Prunella vulgaris spikes, comprising a device body, a first drive motor mounted on the outer surface of the device body, a drive shaft connected to the output end of the first drive motor through the surface of the device body, a seed sieving barrel mounted on one end of the drive shaft by fasteners, a maintenance cover provided on one end of the seed sieving barrel, filter holes opened on the periphery of the seed sieving barrel, a second drive motor mounted on the outer surface of the device body, a main shaft provided at the output end of the second drive motor through the device body and the maintenance cover, the main shaft extending into the inside of the seed sieving barrel, a dispersing shaft provided on the periphery of the main shaft, a pusher plate provided at one end of the dispersing shaft, a striking mechanism provided on the inner wall of the seed sieving barrel, a spring provided inside the striking mechanism, a rubber rod provided at one end of the spring, and the other end of the spring fixed to the inner wall of the seed sieving barrel, multiple striking mechanisms provided, and multiple striking mechanisms are equidistantly arranged around the seed sieving barrel. Inside the seed sieve, a combination of a first drive motor, a transmission shaft, a second drive motor, a main shaft, a dispersing shaft, a dial plate, and a striking mechanism facilitates improved sieving efficiency of Prunella vulgaris seeds. During operation, workers feed the Prunella vulgaris seeds into the sieve through the inlet / outlet hopper. Then, the first and second drive motors are activated. The first drive motor rotates the sieve via the transmission shaft, while the second drive motor rotates the dial plate via the main shaft. During rotation, the dial plate contacts a rubber rod inside the striking mechanism. The rubber rod then bends a spring under pressure. When the dial plate disengages from the rubber rod, the spring's elastic potential energy causes the rubber rod to return to its original position. During this return process, the rubber rod applies force to the Prunella vulgaris seeds inside the sieve, knocking the seeds off and allowing them to be discharged through the filter holes. This method is simple to operate and effectively improves the sieving efficiency of Prunella vulgaris seeds.
[0007] Preferably, multiple dispersing shafts are provided, and the multiple dispersing shafts are installed at equal intervals on one end surface of the dispensing plate. The dispersing shafts are provided with toothed cones on their peripheral surfaces. By providing dispersing shafts, it is convenient for the dispersing shafts to collide with the Prunella vulgaris fruit ears during the rotation of the main shaft. Moreover, the toothed cones on the peripheral surfaces of the dispersing shafts will disperse the Prunella vulgaris fruit ears when they collide, causing the seeds inside to separate from the Prunella vulgaris fruit ears, and then discharge them through the filter holes. This method is simple to operate and further improves its working efficiency.
[0008] Preferably, a collection frame is placed inside the device body below the seed sieve barrel. By setting the collection frame, it is convenient to collect the sieved seeds of Prunella vulgaris.
[0009] Preferably, the surface of the seed sieve barrel is provided with an inlet / outlet hopper, which is fitted with a sealing cover. The inlet / outlet hopper facilitates the entry and exit of the selfheal spikes.
[0010] Preferably, the bottom of the device body is provided with casters, and multiple casters are provided, and the multiple casters are installed at equal intervals on the bottom surface of the device body. By providing casters, it is easy to move the device body, thereby facilitating the operation of the device body.
[0011] Preferably, a controller is installed on the outer surface of the device body, which facilitates the control of the electrical components inside the device body.
[0012] Compared with related technologies, the seed sieving device for Prunella vulgaris spikes provided by this utility model has the following beneficial effects:
[0013] Compared with existing technologies, this Prunella vulgaris seed sieving device, through the coordinated use of a first drive motor, a transmission shaft, a second drive motor, a main shaft, a dispersing shaft, a dial plate, and a striking mechanism, facilitates improved sieving efficiency for Prunella vulgaris seeds. During operation, the operator feeds the Prunella vulgaris seeds into the seed sieving bin through the inlet / outlet hopper. Then, the first and second drive motors are activated. The first drive motor rotates the seed sieving bin via the transmission shaft, while the second drive motor rotates the dial plate via the main shaft. During rotation, the dial plate contacts a rubber rod inside the striking mechanism. The rubber rod then bends a spring under pressure. When the dial plate disengages from the rubber rod, the rubber rod returns to its original position under the elastic potential energy of the spring. During this return process, the rubber rod applies force to the Prunella vulgaris seeds inside the seed sieving bin, knocking the seeds off and allowing them to be discharged through the filter holes. This method is simple to operate and significantly improves the sieving efficiency of Prunella vulgaris seeds.
[0014] Compared with existing technologies, this Prunella vulgaris seed sieving device, by setting a dispersing shaft, facilitates the collision between the dispersing shaft and the Prunella vulgaris seed during the rotation of the main shaft. Moreover, the dispersing shaft is provided with toothed cones on its circumferential side. When colliding with the Prunella vulgaris seed, the toothed cones disperse the seed, causing the seeds inside to separate from the seed and then be discharged through the filter holes. This method is simple to operate and further improves its working efficiency.

A dispersing shaft 16 is provided on the periphery of the main shaft 8, with a push plate 15 at one end. A striking mechanism 12 is provided on the inner wall of the seed sieve 5, with a spring 14 inside. A rubber rod 13 is provided at one end of the spring 14, and the other end of the spring 14 is fixed to the inner wall of the seed sieve 5. Multiple striking mechanisms 12 are provided, and these multiple striking mechanisms 12 are equidistantly arranged around the inside of the seed sieve 5. The coordinated use of the first drive motor 3, transmission shaft 4, second drive motor 9, main shaft 8, dispersing shaft 16, dialing plate 15, and striking mechanism 12 facilitates improved sieving efficiency of Prunella vulgaris fruit spikes and seeds. During operation, the operator feeds the Prunella vulgaris fruit spikes into the seed sieving bin 5 through the inlet / outlet hopper 7, then starts the first drive motor 3 and the second drive motor 9. The first drive motor 3 drives the seed sieving bin 5 to rotate via the transmission shaft 4, while the second drive motor 9 drives the dialing plate 15 to rotate via the main shaft 8. During the rotation, the dial plate 15 will contact the rubber rod 13 inside the striking mechanism 12. Then, the rubber rod 13 will bend the spring 14 under the force. When the dial plate 15 separates from the rubber rod 13, the rubber rod 13 will return to its original position under the elastic potential energy of the spring 14. During the return process, the rubber rod 13 will apply force to contact and strike the Prunella vulgaris fruit spikes inside the seed sieve 5, thereby knocking off the seeds inside. Then, the seeds can be discharged through the filter hole 6. This method is simple to operate and can improve the screening efficiency of Prunella vulgaris fruit spikes and seeds.
[0025] The working principle of the selfheal spike seed sieving device provided by this utility model is as follows:
[0026] In operation, the worker feeds the *Prunella vulgaris* fruit spikes into the seed sieving bin 5 through the inlet / outlet hopper 7. Then, the first drive motor 3 and the second drive motor 9 are activated. The first drive motor 3 rotates the seed sieving bin 5 via the transmission shaft 4, while the second drive motor 9 rotates the dial plate 15 via the main shaft 8. During rotation, the dial plate 15 contacts the rubber rod 13 inside the striking mechanism 12. The rubber rod 13 then bends the spring 14 under pressure. When the dial plate 15 disengages from the rubber rod 13, the rubber rod 13 returns to its original position due to the elastic potential energy of the spring 14. During this return process... In the process, the rubber rod 13 applies force to the Prunella vulgaris fruit spikes inside the seed sieve 5, knocking the seeds off and then discharging them through the filter holes 6. This method is simple to operate and improves the sieving efficiency of Prunella vulgaris fruit spikes and seeds. By setting a dispersing shaft 16, it is easy for the dispersing shaft 16 to collide with the Prunella vulgaris fruit spikes during the rotation of the main shaft 8. Moreover, a toothed cone 17 is set on the circumferential side of the dispersing shaft 16. When it collides with the Prunella vulgaris fruit spikes, the toothed cone 17 will disperse the Prunella vulgaris fruit spikes, causing the seeds inside to separate from the Prunella vulgaris fruit spikes and then be discharged through the filter holes 6. This method is simple to operate and further improves its working efficiency.

During operation, the operator feeds the Prunella vulgaris seed sieving into the seed sieving bin 5 through the inlet / outlet hopper 7. Then, the first drive motor 3 and the second drive motor 9 are activated. The first drive motor 3 drives the seed sieving bin 5 to rotate via the transmission shaft 4, while the second drive motor 9 drives the dial plate 15 to rotate via the main shaft 8. During the rotation of the dial plate 15, it contacts the rubber rod 13 inside the striking mechanism 12. The rubber rod 13 then bends the spring 14 under pressure. The device further facilitates the sieving of Prunella vulgaris seed sieving by using a first drive motor 3, a transmission shaft 4, a second drive motor 9, a main shaft 8, a dispersing shaft 16, a dial plate 15, and a striking mechanism 12. When the rubber rod 13 detaches, it returns to its original position under the elastic potential energy of the spring 14. During the return process, the rubber rod 13 applies force to the Prunella vulgaris fruit spikes inside the seed sieve 5, knocking the seeds off. The seeds are then discharged through the filter hole 6. This method is simple to operate and improves the sieving efficiency of Prunella vulgaris fruit spikes and seeds. By setting a dispersing shaft 16, it is easy for the dispersing shaft 16 to collide with the Prunella vulgaris fruit spikes during the rotation of the main shaft 8.
