Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, specifically to a Yunnan Polygonatum seed screening device. Background Technology

[0002] The rhizome of *Polygonatum yunnanense* is nearly cylindrical or nearly beaded, with irregularly rhomboid nodes that are thickened and have a climbing habit at the stem apex. Leaves are whorled. The dried rhizome is used medicinally, possessing the effects of tonifying qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys. To improve the germination rate of *Polygonatum yunnanense* seeds, they need to be stratified in sand by burying them in a box filled with sand. However, when retrieving the seeds, they must be separated from the sand.

[0003] However, the existing method of separating Polygonatum yunnanense seeds from sand requires manual screening through a filter screen, which is inefficient and does not meet current needs. Therefore, we propose a Polygonatum yunnanense seed screening device. Utility Model Content

[0004] The purpose of this invention is to provide a Yunnan Polygonatum seed screening device to solve the problems mentioned in the background art, such as the need for manual screening through a filter screen in the existing Yunnan Polygonatum seed and sand separation operations, which result in low screening efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seed screening device for Polygonatum yunnanense, comprising a base, through grooves provided on the upper sides of both sides of the inner wall of the base, a filter assembly movably disposed on the inner side of the through grooves, an annular slot provided on the upper end face of the base, an annular insert plate movably installed on the inner side of the annular slot through a movable disassembly mechanism, an annular plate fixedly connected to the upper end face of the annular insert plate, a toggle assembly installed on the inner side of the annular plate, the toggle assembly comprising a support plate, a motor mounted on the upper end face of the support plate, a rotating shaft provided below the support plate, a strip plate mounted on the outer surface of the rotating shaft, and a brush plate provided below the strip plate.

[0006] Preferably, the filter assembly includes a filter plate, with connecting blocks installed on both sides of the outer surface of the filter plate, a collection groove provided on the upper end face of the filter plate, and a circular groove provided in the middle of the upper end face of the collection groove.

[0007] Preferably, the output end of the motor is fixedly connected to the upper end face of the rotating shaft via a coupling, and the lower end face of the rotating shaft can be inserted into the inner side of the circular groove.

[0008] Preferably, a first magnet is installed inside the strip plate, and a second magnet is installed on the inner side of the brush plate, with the magnetic poles of the first magnet and the second magnet being opposite, and the connecting block can be snapped into the inner side of the through groove.

[0009] Preferably, the movable disassembly mechanism includes a plug rod, which is installed on the front and rear faces of the base through a through hole. A first spring is sleeved on the outer surface of the plug rod, and an arc-shaped plate is fixedly connected to the opposite side of the outer surfaces of the two plug rods.

[0010] Preferably, the other end of the insertion rod is fixedly connected to a locking block, the inner wall of the through hole is provided with a groove, and the front and rear faces of the annular insertion plate are both provided with locking slots.

[0011] Preferably, the card block can be inserted into the inside of the card slot, the size of the card block is smaller than the size of the groove, and a second spring is installed on the bottom surface of the annular slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by incorporating a toggle component and a filter component, allows the seeds of Polygonatum yunnanense to be screened to be poured into the inner side of an annular plate. The seeds are positioned above the filter plate. When the motor is turned on, it drives the rotating shaft, which in turn rotates the strip plate around the shaft, causing the brush plate to rotate and spread the accumulated seeds evenly. The continuous aggle of the brush causes the seeds to tumble on the filter plate, greatly increasing the contact between the seeds and the filter plate and accelerating the passage of sand. This allows the sand remaining on the seeds to fall into the base through the filter plate, and the screened seeds can be collected in the collection trough. This utility model, by incorporating a toggle component, improves screening efficiency and solves the problem of low efficiency in manual screening.

[0014] 2. This utility model features a movable disassembly mechanism. After screening, the two arc-shaped plates are simultaneously pulled to both sides. The movement of the arc-shaped plates causes the insert rod to move, and the locking block leaves the inner side of the slot. After retracting into the inner side of the groove, the limiting position on the annular insert plate is released. Under the action of the second spring, the annular insert plate is pushed upward, making it convenient for workers to remove the annular plate from the top of the base. The filter assembly can be taken out from the base to obtain the screened Polygonatum yunnanense seeds. It also facilitates the cleaning of the sand collected in the base and allows the brush plate to be disassembled for easy cleaning. This utility model is easy to disassemble and assemble, facilitates the obtaining of screened Polygonatum yunnanense seeds, and facilitates the cleaning of the filter plate and brush plate.

[0023] like Figure 2 As shown, the filter assembly 6 includes a filter plate 601. Connecting blocks 603 are installed on both sides of the outer surface of the filter plate 601. A collection groove 604 is provided on the upper end face of the filter plate 601. A circular groove 602 is provided in the middle of the upper end face of the collection groove 604. The seeds to be screened can remain inside the collection groove 604. Slots are provided on both sides of the lower end face of the annular insert plate 5, and the connecting blocks 603 can be inserted into the inside of the slots to ensure that the annular insert plate 5 can be inserted into the inside of the annular slot 7.

[0024] The output end of the motor 201 is fixedly connected to the upper end face of the rotating shaft 203 through a coupling. The lower end face of the rotating shaft 203 can be inserted into the inner side of the circular groove 602. When the motor 201 works, it can drive the rotating shaft 203 to rotate, thereby improving the stability of the rotation of the rotating shaft 203.

[0025] like Figure 3 As shown, a first magnet is installed inside the strip plate 204, and a second magnet is installed inside the brush plate 205. The magnetic poles of the first magnet and the second magnet are opposite. The connecting block 603 can be inserted into the inside of the through groove 8, and the brush plate 205 can be removed from below the strip plate 204 to clean the bristles. The lower end face of the brush plate 205 is in contact with the upper end face of the collection groove 604.

[0026] like Figure 4 As shown, the movable disassembly mechanism 3 includes a plug rod 303. The plug rod 303 is installed on the front and rear faces of the base 4 through the through hole 305. A first spring 304 is sleeved on the outer surface of the plug rod 303. An arc plate 302 is fixedly connected to the opposite side of the outer surfaces of the two plug rods 303. The plug rods 303 can be moved by the arc plate 302.

[0027] The other end of the insertion rod 303 is fixedly connected to a locking block 307, the inner wall of the through hole 305 is provided with a groove 306, and the front and rear faces of the annular insertion plate 5 are both provided with locking slots 301.

[0028] The locking block 307 can be inserted into the inside of the slot 301. The size of the locking block 307 is smaller than the size of the groove 306.

[0029] Working Principle: When using this *Polygonatum yunnanense* seed screening device, first connect the power supply, then pour the *Polygonatum yunnanense* seeds to be screened into the inner side of the annular plate 1, above the filter plate 601. Turn on the motor 201, which drives the rotating shaft 203 to rotate, thereby causing the strip plate 204 to rotate around the rotating shaft 203, and driving the brush plate 205 to rotate, spreading the accumulated *Polygonatum yunnanense* seeds evenly. The continuous movement of the brush causes the seeds to tumble on the filter plate 601, greatly increasing the contact opportunity between the seeds and the filter plate 601, accelerating the passage of sand and soil. This allows the sand and soil remaining on the *Polygonatum yunnanense* seeds to fall into the base 4 through the filter plate 601. The screened *Polygonatum yunnanense* seeds can be collected in the collection trough 604, and are then removed by a movable detachment mechanism. The unloading mechanism 3, after screening is completed, simultaneously pulls the two arc-shaped plates 302 to both sides. The movement of the arc-shaped plates 302 drives the insertion rod 303 to move. The locking block 307 leaves the inner side of the locking groove 301 and retracts into the inner side of the groove 306, releasing the limitation on the annular insertion plate 5. Under the action of the second spring 308, the annular insertion plate 5 is pushed upward, making it convenient for the staff to remove the annular plate 1 from the top of the base 4. The filter assembly 6 can be taken out from the base 4 to obtain the screened Solomon's seal seeds. At the same time, it is convenient to clean the sand collected in the base 4, and the brush plate 205 can be disassembled for easy cleaning. This utility model is easy to disassemble and assemble, and convenient to clean the filter plate 601 and the brush plate 205. In addition, the screening efficiency is improved by setting the actuating component 2.
