Description

Technical Field

[0001] This utility model belongs to the field of cardamom cultivation technology, and in particular relates to a sieving device for cardamom cultivation. Background Technology

[0002] Amomum villosum is a plant with important medicinal and economic value. Its fruit is widely used in traditional Chinese medicine, food and spice industries. In the cultivation of Amomum villosum, the quality of the seeds directly affects the germination rate, seedling growth and final yield. Due to individual differences in Amomum villosum seeds during natural growth or artificial harvesting, their size is often uneven. It is often necessary to grade the seeds according to their size to ensure that the seeds are of uniform size, thereby improving the germination rate and the uniformity of seedling growth.

[0003] Traditional sieving usually relies on manual labor or vibrating screens. Manual sieving requires frequent screen replacements, increasing labor intensity and production costs. When sieving Amomum villosum seeds using vibrating screens, fixed aperture screens are often used, and the seeds are sieved by vibration or rotation. Since Amomum villosum seeds vary greatly in size, smaller seeds are more likely to leak through screens with larger apertures, resulting in mixing of seeds of different sizes and affecting the sieving effect. Utility Model Content

[0004] The purpose of this invention is to provide a sieving device for cultivating Amomum villosum, which can effectively sieve Amomum villosum seeds of different sizes.

[0005] The aforementioned sieving device for cultivating Amomum villosum includes a sieving box with an opening at the top. A fixing groove is provided on the front side wall of the sieving box, and several collection baskets for collecting Amomum villosum seeds are arranged in the fixing groove. A sieving plate is arranged inside the sieving box, and several partitions are arranged between the sieving plate and the collection baskets. Several through-hole groups are opened on the sieving plate corresponding to the collection baskets. Each through-hole group includes several screening holes, and the diameter of the screening holes in each through-hole group is different. A sealing component for sealing the screening holes is arranged below each through-hole group. A mounting frame is arranged on the top of the sieving box, and a motor is installed at the bottom of the mounting frame. A fixing rod is arranged on the output shaft of the motor, and a fixing plate is arranged at the bottom of the fixing rod. Several stirring rods for pushing Amomum villosum seeds are arranged at the bottom of the fixing plate.

[0006] Furthermore, the sealing assembly includes a mounting frame fixed below several through-hole groups, one side of the mounting frame extending out of the front side wall of the screening box, a sealing plate that slides with the mounting frame and seals the screening holes, and an electric push rod installed in the mounting frame for pushing the sealing plate to seal or clear the screening holes.

[0007] Furthermore, a limiting groove is provided at the bottom of the partition, and a limiting block is provided in the limiting groove to slide with it and fixed to the top of the collection basket.

[0008] Furthermore, the top of the screening plate is provided with a baffle with an annular structure.

[0009] Furthermore, the side wall of the fixed plate is provided with a scraper that contacts the inner wall of the baffle, and the bottom of the scraper contacts the top of the screening plate.

[0010] Furthermore, the aperture size of the screen holes in several through-hole groups decreases sequentially from left to right.

[0011] Furthermore, the stirring rod is made of rubber material.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a sealing component to block several screening holes in the through-hole assembly. The cardamom seeds are then poured onto the top of the screening plate. The motor is started, causing its output shaft to rotate, which in turn rotates the fixed plate. Several stirring rods then rotate and push the cardamom seeds, causing them to fall sequentially from the smallest to the largest screening holes into the corresponding collection baskets. This effectively separates cardamom seeds of different sizes, improving screening efficiency and facilitating subsequent seed cultivation. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0015] Example The sieving device for cultivating Amomum villosum described in this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the sieve box 1 has an opening at the top. The front side wall of the sieve box 1 has a fixing groove. Several collection baskets 12 for collecting cardamom seeds are set in the fixing groove. A sieve plate 2 is set inside the sieve box 1. Several partitions 8 are set between the sieve plate 2 and the collection baskets 12. Several through hole groups are set on the sieve plate 2 corresponding to several collection baskets 12. Each through hole group includes several screening holes 3. The diameter of the screening holes 3 in each through hole group is different. A sealing component for sealing the screening holes 3 is set below each through hole group. A mounting frame 7 is set at the top of the sieve box 1. A motor 6 is installed at the bottom of the mounting frame 7. A fixing rod 5 is set on the output shaft of the motor 6. A fixing plate 13 is set at the bottom of the fixing rod 5. Several stirring rods 4 for pushing cardamom seeds are set at the bottom of the fixing plate 13. The sieving box 1 is equipped with at least three collection baskets 12. The collection baskets 12 are inserted into the sieving box 1 through a fixing groove on the front side wall of the sieving box 1. At least two partitions 8 are welded or glued to the inner wall of the sieving box 1. The top of the partitions 8 is equipped with sieving plates 2 welded or glued to the inner wall of the sieving box 1. The sieving plates 2, partitions 8, and collection baskets 12 divide the interior of the sieving box 1 into three independent chambers. Different sizes of cardamom seeds are sieved through the three independent chambers. Through-hole groups are opened on the sieving plates 2 in the three chambers. Each through-hole group includes several sieving plates 2. The aperture size of the sieving plates 2 in each through-hole group is different, so that cardamom seeds of different sizes can fall into the corresponding collection baskets 12 through the sieving plates 2 with different aperture sizes for collection. Each chamber is equipped with a sealing component to seal the several sieving plates 2 in the three through-hole groups. The sealing assembly includes three through slots on the front side wall of the screening box 1. A sealing plate 10 is installed in each through slot, and a slide rail is mounted on the sealing plate 10. Corresponding to the slide rail, a guide rail is installed on the inner wall of the through slot, slidingly engaging with the slide rail. Through the interaction of the slide rail and the guide rail, the sealing plate 10 moves below the screening plate 2. Moving the sealing plate 10 clears the smallest aperture screen holes 3, allowing small-sized cardamom seeds poured onto the screening plate 2 to pass through several of the smallest aperture screen holes. The material falls into the corresponding collection basket 12 through the material hole 3. Then, the sealing plate 10 is loosened to block the material hole 3 in sequence according to the hole size from small to large, so that the cardamom seeds of different sizes fall into the corresponding collection basket 12 in sequence. The cardamom seeds of different sizes are screened. The sealing plate 10 blocks or clears several material holes 3. The sliding cooperation of the guide rail and slide rail that will not detach prevents the sealing plate 10 from detaching from the through groove, ensuring the stability of its installation. The top of the screening box 1 is welded or glued with a mounting frame 7 in the shape of a "door". The bottom of the horizontal plate of the mounting frame 7 is welded or threaded with a motor 6. The output shaft of the motor 6 is welded with a vertically set fixing rod 5. The bottom of the fixing rod 5 is threaded with a fixing plate 13. Several stirring rods 4 are glued to the bottom of the fixing plate 13. The mounting frame 7 is equipped with a battery for providing power to the motor 6. When in use, the motor is started so that its output shaft drives the fixing rod 5 to rotate. The fixing rod 5 drives the fixing plate 13 to rotate, which in turn pushes the cardamom seeds on the screening plate 2 to rotate and push them through several screening holes 3 of three through holes with diameters from small to large. Cardamom seeds of different sizes are pushed by the stirring rods 4 to fall from the screening holes 3 of the corresponding diameter into the collection basket 12 for collection. like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the sealing assembly includes a mounting frame 11 fixed below several through-hole groups. One side of the mounting frame 11 extends out of the front sidewall of the screening box 1. A sealing plate 10, which slides within the mounting frame 11 and seals the screening holes 3, is installed inside the mounting frame 11. An electric push rod 14, used to push the sealing plate 10 to seal or clear the screening holes 3, is also installed inside the mounting frame 11. At least three mounting slots are provided on the front sidewall of the screening box 1. The mounting frame 11 is welded or glued into the mounting slots. The opening of the mounting frame 11 faces the inner wall of the screening box 1. A portion of the mounting frame 11 extends out of the mounting slot and is located within the screening hole. On the front side of box 1, an electric push rod 14 is installed inside the mounting frame 11. A sealing plate 10 is welded or glued to the end of the push rod 14. A sliding groove is provided on the side wall of the sealing plate 10. A slider is provided on the inner wall of the mounting frame 11, which slides in cooperation with the sliding groove. The sliding cooperation between the slider and the groove allows the sealing plate 10 to move more smoothly within the electric push rod 14, preventing the sealing plate 10 from detaching from the mounting frame 11 and ensuring the stability of the connection. In use, the electric push rod 14 is activated, causing its push rod to extend and retract within the base, thereby moving the sealing plate 10 within the mounting frame 11. When the rear side wall of the sealing plate 10 is pushed to fit against the inner rear side wall of the screening box 1, the sealing plate 10 seals several screening holes 3 of the three through-hole groups. Then, the cardamom seeds are poured onto the screening plate 2. The electric push rod 14 is activated, causing its end to move the sealing plate 10 into the mounting frame 11. First, several screening holes 3 with the smallest diameter are cleared, allowing small-sized cardamom seeds to fall into the collection basket 12 through these holes. Then, after sealing the small-diameter screening holes 3, the medium-diameter screening holes 3 are cleared to screen the medium-sized cardamom seeds. After sealing the holes, the largest sieve holes 3 are cleared to allow large seeds to fall into the collection basket 12. Through multi-stage sieving, the seeds are grouped into small, medium, and large sizes to ensure that the size of each group is roughly the same, which is convenient for subsequent cultivation and planting. Seeds of roughly the same size have a closer germination rate and growth rate, which is beneficial for field management. The proportion of seeds of each grade is counted to evaluate batch quality or optimize planting and seed selection. After grading, seeds are sown as needed to ensure uniform emergence and facilitate water and fertilizer management. After grading, seeds can be used according to needs, such as small seeds for seedling cultivation and large seeds for sale, reducing waste. like Figure 1 , Figure 3 and Figure 4As shown, the bottom of the partition 8 has a limiting groove, and a limiting block that slides with the limiting groove and is fixed to the top of the collection basket 12 is provided in the limiting groove; the collection basket 12 and the limiting block are integrally formed, which is convenient for production and use; the left and right inner walls of the sieving box 1 are provided with grooves for the collection basket 12 to be embedded, and the grooves are provided with limiting grooves that slide with the limiting block in a back-to-back manner. The limiting groove at the bottom of the partition 8 extends to and penetrates the front side wall of the sieving box 1. In use, the collection basket 12 is slid into the sieving box 1 from the fixing groove on the front side wall of the sieving box 1, and the limiting block at the top of the collection basket 12 slides into the limiting groove at the bottom of the partition 8 from the limiting groove on the front side wall of the sieving box 1, fixing the position of the collection basket 12. The sieving plate 2, the partition 8 and the collection basket 12 divide the interior of the sieving box 1 into several independent chambers, avoiding the mixing of different sizes of cardamom seeds, which is more conducive to sieving and easier to cultivate. like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the sieve plate 2 is provided with a ring-shaped baffle 9; the top of the sieve plate 2 is welded or glued with a ring-shaped baffle 9, and the screening holes 3 of several through-hole groups on the sieve plate 2 are all located on the sieve plate 2 below the baffle 9. The cardamom seeds are poured onto the sieve plate 2 inside the baffle 9, and the cardamom seeds are screened by the size of the three through-hole groups of screening holes 3. This prevents the cardamom seeds from moving to the connection between the sieve box 1 and the sieve plate 2 during the pushing process, and prevents them from accumulating in corners. The baffle 9 is ring-shaped, and the cardamom seeds are rotated and pushed by the stirring rod 4 to keep them always inside the baffle 9, avoiding dead corners and making the screening smoother and more efficient. Moreover, the three different hole diameters can screen out small, medium and large grades of seeds, ensuring that the size of each group of seeds is similar, improving the consistency of planting or processing. Cardamom seeds of similar size have a more consistent germination rate and growth rate, which is convenient for irrigation and fertilization and is more conducive to cultivation. like Figure 2 , Figure 3 and Figure 4 As shown, the side wall of the fixing plate 13 is provided with a scraper 15 that contacts the inner wall of the baffle 9, and the bottom of the scraper 15 contacts the top of the sieve plate 2; the scraper 15 is glued to the side wall of the fixing plate 13. The scraper 15 is made of silicone material, which is soft and elastic to prevent it from making abnormal noise when it contacts the inner wall of the baffle 9 and the top of the sieve plate 2, and also to avoid damage to both; the scraper 15 can rotate and push the cardamom seeds accumulated at the connection between the baffle 9 and the sieve plate 2, so that they fall through the sieve hole 3 into the corresponding collection basket 12, so as to avoid the cardamom seeds accumulating in the corner as much as possible; like Figure 1As shown, the diameter of the screening holes 3 in several through-hole groups decreases from left to right; the diameter of the screening holes 3 in the leftmost through-hole group is the largest, and the diameter of the screening holes 3 in the rightmost through-hole group is the smallest. Moving the corresponding sealing plate 10 from right to left gradually clears the holes 3 from small to large, so that the size of the cardamom seeds on the screening plate 2 is gradually screened from small to large. This can prevent small cardamom seeds from falling through the large-diameter screening holes 3, and can more accurately distinguish and collect cardamom seeds, thus improving its screening efficiency. like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stirring rod 4 is made of rubber material; rubber is soft and elastic, and its softness can prevent the seeds from being damaged when the stirring rod 4 pushes the cardamom seeds to move on the sieve plate 2; when the fixed plate 13 rotates, several stirring rods 4 will be inserted into the sieve holes 3 to clear the blockage of the stirring rods 4 and prevent them from becoming clogged, thus enabling better sieving of the cardamom seeds. In addition, the diameter of the stirring rod 4 is smaller than that of the smallest diameter sieve hole 3, which makes it easy for the stirring rod 4 to smoothly extend into the sieve hole 3 to clear the blockage of the cardamom seeds and ensure the sieving effect. In practical use, the sealing components are used to block several screening holes 3 of several through-hole groups, and several collection baskets 12 are moved from the fixed groove to the inside of the screening box 1. The screening box 1 is divided into several independent chambers by the screening plate 2, the partition plate 8, and the screening plate 2. Then, the cardamom seeds are poured onto the top of the screening plate 2, and the motor 6 is started so that its output shaft drives the fixed rod 5 to rotate. The fixed rod 5 drives the fixed plate 13 to rotate, and the several stirring rods 4 at the bottom of the fixed plate 13 rotate and push the cardamom seeds, gradually opening up the screening holes 3 of several through-hole groups from small to large. The stirring rods 4 push the cardamom seeds from small to large size for screening. After passing through different chambers, they fall into the corresponding collection baskets 12, thus screening cardamom seeds of different sizes, which can significantly improve screening efficiency and make the seeds more suitable for cultivation and planting.
