Description

A grading and screening device for pomegranate breeding Technical Field

[0001] This utility model relates to the field of pomegranate seed screening technology, specifically to a grading and screening device for pomegranate breeding. Background Technology

[0002] Pomegranate breeding refers to the process of improving the genetic characteristics of pomegranates through artificial selection, hybridization, mutagenesis, and other methods to cultivate new varieties with higher yields, better quality, stronger resistance, or other specific superior traits. The grading and screening equipment used in pomegranate breeding is used to precisely screen breeding materials (such as seeds, seedlings, and fruits) in order to accelerate the breeding process.

[0003] The patent document with authorization announcement number CN218574290U describes a screening and grading device for rice breeding. The described scheme uses a filter screen to filter the first batch of seeds passing through the collection box, effectively filtering out impurities carried by the seeds. This improves the efficiency and quality of subsequent seed screening and grading. Furthermore, the two ends of the filter screen are connected to support rods to guide and support the seeds inside the collection box, making it easy to remove the filter screen later and process the filtered impurities.

[0004] The above-mentioned technology has the problem of not being able to adjust the size of the screening according to actual needs. Different varieties of pomegranates have different seed sizes and shapes. If the screening size is fixed, it is impossible to accurately distinguish between different varieties of pomegranates. This may lead to some excellent varieties that should be retained being mistakenly judged as unqualified and eliminated, or some inferior varieties being retained, affecting breeding efficiency and quality. In addition, the above-mentioned technology also has the problem of not being able to feed and screen evenly. Uneven feeding will cause the number of seeds that the sorting mechanism needs to process to vary, which can easily cause congestion and reduce the sorting speed. Summary of the Invention

Detailed Implementation

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] As shown in Figures 1-6, this embodiment provides a grading and screening device for pomegranate breeding, including a sieving box 100; it also includes a sieving assembly for sieving pomegranate seeds, the sieving assembly including two first sieving plates 201, the two first sieving plates 201 being respectively disposed at both ends inside the sieving box 100, a second sieving plate 202 being slidably connected to the top of each of the two first sieving plates 201, a plurality of sliding grooves 203 being provided on both sides of each of the two first sieving plates 201, and a plurality of limiting blocks 20 being provided on both sides of the bottom of each of the two second sieving plates 202. 4. Several limiting blocks 204 are slidably connected to several sliding grooves 203. The second sieve plate 202 is provided with an adjustment component for adjusting the second sieve plate 202. The bottom of the first sieve plate 201 is provided with a vibration component for vibrating the first sieve plate 201. The top of the sieve box 100 is provided with a conveying component for conveying pomegranate seeds. The sides of the sieve box 100 are provided with lifting components for raising and lowering the sieve box 100. The pomegranate seeds are screened by the cooperation of the first sieve plate 201 and the second sieve plate 202.

[0028] As shown in Figures 1, 2, 3, 4, and 5, the adjusting assembly includes several hollow columns 301, which are respectively disposed at both ends of the two second screening plates 202. Each hollow column 301 has a slidably connected limit pin 302 inside. A first spring 303 is provided between the top of each hollow column 301 and the limit pin 302. Each limit pin 302 has a pull rod 304 at its top, which is slidably connected inside the hollow columns 301. Several limit pins adapted to the limit pins 302 are provided on both sides of the two first screening plates 201. Hole 305, by pulling the pull rod 304, causes the limiting pin 302 to squeeze the first spring 303 and move away from the limiting hole 305, so that the second sieve plate 202 can slide on the first sieve plate 201, thereby adjusting the overlapping area of ​​the sieve holes on the first sieve plate 201 and the second sieve plate 202, thus accommodating pomegranate seeds of different sizes. After the adjustment is completed, the pulling force on the pull rod 304 is released, and then under the action of the first spring 303, it causes the limiting pin 302 to enter the limiting hole 305, thereby limiting the second sieve plate 202.

[0029] As shown in Figure 4, one end of several pull rods 304 away from the limiting pin 302 passes through several hollow pins 301 and is provided with a pull ring, which facilitates pulling the pull rods 304.

[0030] As shown in Figures 2, 3, 5, and 6, the vibration assembly includes several support plates 401, which are respectively disposed at both ends of the two first screening plates 201. Several limiting grooves 402 are provided on both sides of the interior of the screening box 100, and the support plates 401 are slidably connected to the interior of the limiting grooves 402. Second springs 403 are provided between the top and bottom of the support plates 401 and the limiting grooves 402. Connecting rods 404 are provided between the support plates 401 on both sides, and the connecting rods 404 are slidably connected to the interior of the screening box 100 around the perimeter. The bottom of the lower first screening plate 201... A vibration motor 405 is installed. By starting the vibration motor 405, it drives a first screening plate 201 to vibrate, which in turn drives the surrounding support plates 401 to slide inside the limiting groove 402, thereby squeezing the second spring 403. As the support plates 401 vibrate continuously, under the action of the relative second spring 403, the support plates 401 drive the first screening plate 201 to reciprocate. When the lower first screening plate 201 vibrates and reciprocates, it will also drive the upper support plate 401 and the first screening plate 201 to reciprocate under the action of several connecting rods 404.

[0031] As shown in Figures 1, 2, and 5, the conveying assembly includes a conveying frame 501, which is located at the top of the sieving box 100. A drive motor 502 is provided at one end of the sieving box 100. The output end of the drive motor 502 passes through the sieving box 100 and the conveying frame 501 and is provided with a spiral conveying rod 503. The spiral conveying rod 503 is rotatably connected to the inside of the conveying frame 501. A feed inlet 504 is provided at one end of the top of the sieving box 100, and the bottom of the feed inlet 504 is connected to the conveying frame 501. A discharge port 505 is provided at one end of the bottom of the conveying frame 501. By adding pomegranate seeds to be sieved into the feed inlet 504, and then starting the drive motor 502, it drives the spiral conveying rod 503 to rotate, thereby carrying the pomegranate seeds to the discharge port 505, where they fall onto a second sieving plate 202.

[0032] As shown in Figure 1, the lifting assembly includes two support bars 601, which are respectively located on both sides of the screening box 100. Both ends of the bottom of the two support bars 601 are provided with telescopic ends of telescopic columns 602. A fixing bar is provided between the two telescopic columns 602 on both sides. An electric telescopic rod 603 is installed on each of the two fixing bars. The output ends of the two electric telescopic rods 603 are respectively located at the bottom of the two support bars 601. By activating the two electric telescopic rods 603, the two support bars 601 and the screening box 100 are lifted and lowered under the action of the telescopic columns 602.

[0033] As shown in Figures 2 and 5, the sieving box 100 is provided with a guide plate 700, which is located between two first sieving plates 201. The guide plate 700 guides the seeds falling into the sieving holes of the upper first sieving plate 201 and the second sieving plate 202 to one side of the lower second sieving plate 202.

[0034] As shown in Figures 1, 2 and 5, side outlets are provided at both ends of one side of the sieve box 100, and the ends of the two first sieve plates 201 near the side outlets are lower than the ends away from the side outlets, forming an inclined structure, which facilitates the discharge of seeds that have not passed through the sieve holes from the side outlets.

[0035] The working principle of this utility model is as follows: Based on actual needs, adjusting the positions of the two second sieve plates 202 on the two sieve plates 201 allows the pull rod 304 to be pulled, causing the limiting pin 302 to press against the first spring 303 and move away from the limiting hole 305. Subsequently, pulling the second sieve plates 202 causes the limiting block 204 to slide inside the sliding groove 203, allowing the second sieve plates 202 to slide on the first sieve plate 201. This adjusts the overlapping area of ​​the sieve holes on the first sieve plate 201 and the second sieve plate 202, thus accommodating pomegranate seeds of different sizes. After adjustment, the adjustment is completed. The pulling force of the pull rod 304, under the action of the first spring 303, causes it to drive the limiting pin 302 into the limiting hole 305, thereby limiting the second screening plate 202. Then, the two electric telescopic rods 603 are activated, and under the action of several telescopic pins 602, they drive the two support bars 601 and the screening box 100 to rise and fall, so that a collection frame can be placed inside the screening box 100. Then, collection frames are also placed below the two first screening plates 201. Then, pomegranate seeds to be screened are added into the feed inlet 504. Then, the drive motor 502 is activated, causing it to drive the screw conveyor 503 to enter. The rotating mechanism carries pomegranate seeds to the discharge port 505, where they fall onto a second sieve plate 202. The vibrating motor 405 then activates, causing a first sieve plate 201 to vibrate. This vibrates the surrounding support plates 401, which slide within the limiting grooves 402, compressing the second springs 403. As the support plates 401 vibrate, the relative movement of the second springs 403 causes the support plates 401 to reciprocate, driving the first sieve plate 201 to bounce back and forth. Simultaneously, the lower first sieve plate 201, vibrating and bouncing, also drives the upper support plates 401 through the action of several connecting rods 404. The plate 401 and the first sieve plate 201 reciprocate, while the two first sieve plates 201, under the action of the limiting block 204, drive the two second sieve plates 202 to jump synchronously, thereby sieving the seeds. Seeds falling into the sieve holes of the upper first sieve plate 201 and the second sieve plate 202 are guided to the side of the lower second sieve plate 202 by the guide plate 700, thereby further screening out seeds of different sizes. After sieving is completed, the electric telescopic rod 603 can be activated again to drive the sieve box 100 to rise and fall, so that the collection frame inside can be retrieved.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
