Description

Technical Field

[0001] This utility model relates to the field of seed treatment technology, and in particular to a seed screening and grading device for breeding cucurbit vegetables. Background Technology

[0002] Seed screening and grading devices are specialized equipment used in the breeding of cucurbit vegetables. Their core function is to automatically and systematically screen and grade cucurbit vegetable seeds according to preset physical or physiological indicators, ultimately obtaining seed batches with uniform quality and stable traits. Seed screening and grading ensures that seeds are uniform in size and plumpness, germinate at the same time after sowing, and grow seedlings uniformly. This facilitates subsequent field operations such as water and fertilizer management and pest and disease control, reduces the proportion of weak and deformed seedlings, and does not interfere with the reliability of experimental data when seeds are used for experiments, enabling accurate judgment of the quality of strains.

[0003] Currently, existing equipment requires two separate operations to screen seeds, one for size and the other for impurities such as shriveled seeds, empty shells, or debris. This not only prolongs processing time but also necessitates additional equipment or manual intervention, increasing time and labor costs. If grading is performed before impurity removal, lightweight impurities can easily mix with seeds of different sizes, resulting in insufficient purity of the graded seeds. If impurity removal is performed before grading, impurities may be introduced again during the process, affecting the final quality. Therefore, this utility model is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figures 1-6A seed screening and grading device for cucurbit vegetable breeding includes a box body 1 and a feed inlet 101 located at the top of the box body 1. The box body 1 is also provided with a discharge plate 102 corresponding to the position of the feed inlet 101. A folding plate 103 is provided inside the box body 1. A fan 5 is fixedly connected inside the box body 1 and is located at the bottom of the discharge plate 102. Multiple partitions 4 are provided on the bottom inner wall of the box body 1. A grading zone is formed between two adjacent partitions 4. Each grading zone includes at least one rod 401. In two adjacent grading zones, the distance between the rods 401 gradually increases from the middle position of the box body 1 to both sides.

[0030] In this invention, during use, the seeds of melons and vegetables that need to be screened and graded are first put into the feed inlet 101. The seeds then fall into the feed plate 102 through the feed inlet 101. Since the feed plate 102 is inclined, the seeds will slide off the feed plate 102. At the same time, the fan 5 located at the bottom of the feed plate 102 is activated. The fan 5 can blow away the lighter impurities in the sliding seeds. The lighter impurities are usually shriveled seeds, empty shells, or fragments. Then, they are put into the folding plate 103. The falling seeds will then enter the grading area. The grading area is inclined, that is, multiple rods 401 gradually tilt downwards from the center of the box 1 to both sides. Therefore, the falling seeds can gradually move to both sides under the action of the rods 401. The distance between the rods 401 gradually increases from the middle position of the box 1 to both sides, so that seeds of different sizes can fall from different positions, thereby realizing the seed grading operation.

[0031] It should also be noted that the fan 5 in this application is specifically an integrated power supply type. The fan 5 has its own power supply, which can directly control the start of the fan 5, thereby blowing away lighter impurities. Multiple fans 5 can be set according to the actual application, and then fixedly installed on the inner wall of the box 1 by connecting rods.

[0032] Reference Figures 2-5 The inner wall of the box 1 is also provided with two U-shaped blocks 2, and an elastic cloth 201 is connected between the two U-shaped blocks 2. Multiple grading areas are respectively set on both sides of the elastic cloth 201.

[0033] In this invention, the elastic cloth 201 can provide some protection for the falling seeds, that is, the falling seeds can be cushioned by the elastic cloth 201 and will not be damaged.

[0034] Reference Figures 2-5 The U-shaped block 2 has a sliding connection to a pressure plate 202 for fixing both sides of the elastic cloth 201. An adjusting rod 203 is rotatably connected to the pressure plate 202. The adjusting rod 203 is threadedly connected to the U-shaped block 2. The pressure plate 202 is also provided with a limiting rod 204, which is slidably connected to the U-shaped block 2.

[0035] By rotating the adjusting rod 203, the adjusting rod 203 can drive the pressure plate 202 to move under the action of the threaded connection between the adjusting rod 203 and the U-shaped block 2, so that the pressure plate 202 squeezes the two ends of the elastic cloth 201, making the two ends of the elastic cloth 201 easy to install. When installing the whole, the internal structure is fixed first, and then the multiple sides of the box 1 can be assembled.

[0036] A fixing plate 206 is fixedly installed on the inner wall of the box 1. A push block 205 is slidably connected inside the box 1. A guide rod 207 is provided at the bottom of the push block 205. The guide rod 207 is slidably connected to the fixing plate 206.

[0037] The bottom inner wall of the housing 1 is provided with an L plate 3, and a motor 301 is fixedly connected to the L plate 3. The output end of the motor 301 is connected to a cam 302, and the cam 302 cooperates with the bottom of the push block 205.

[0038] In this invention, by starting the motor 301, the output cam 302 is rotated, which in turn drives the push block 205 to move upward. When the push block 205 moves upward, it pushes the elastic cloth 201, causing the seeds on the elastic cloth 201 to fall off, thus preventing the seeds from remaining on the elastic cloth 201 and failing to achieve the grading effect.

[0039] Reference Figure 6 A drawer 402 is slidably connected to the bottom of the box 1. The drawer 402 has multiple uprights 404 corresponding to the partitions 4 inside, and a pull rod 403 is provided on the outer wall of the drawer 402.

[0040] The graded seeds will fall into the drawer 402. The upright plate 404 can separate seeds of different sizes to achieve the grading operation.

[0041] Reference Figures 1-4 The feed inlet 101 is provided with a diversion plate 106, and multiple folding plates 103 are provided. The box body 1 is provided with a through groove corresponding to the folding plate 103. The outer wall of the box body 1 is provided with a limiting frame 104. The bottom of the limiting frame 104 is provided with a discharge port 105. The through groove is connected to the limiting frame 104.

[0042] In this invention, after the seeds are placed into the feed inlet 101, they will fall onto the feed plate 102 again under the action of the diversion plate 106, thereby reducing the falling speed of the seeds and causing them to fall slowly. The blower 5 blows lighter impurities into multiple folding plates 103, and then into the limiting frame 104 through the through groove, and then discharged through the discharge port 105 at the bottom.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
