[0002] Plant cultivation is the agricultural production sector that cultivates various crops and obtains plant products. Crop cultivation is one of the main components of agriculture. It is a social production sector that utilizes the life functions of plants to obtain food, by-products, feed, and industrial raw materials through artificial cultivation. It includes the cultivation of various crops, trees, fruit trees, medicinal and ornamental plants, such as food crops, cash crops, vegetable crops, green manure crops, feed crops, pasture grass, flowers, and other horticultural crops. In China, it usually refers to the production of crops such as grains, cotton, oil, sugar, hemp, silk, tobacco, tea, fruits, medicinal herbs, and miscellaneous crops. It also refers to agriculture in a narrow sense, also known as crop cultivation. Seeds are an essential raw material in crop cultivation.

[0003] In existing technologies, it is difficult to distinguish between different types or qualities of seeds when they are mixed during agricultural planting. This requires manual sorting by staff or manual sieving using sieves. Only one type of seed can be sorted at a time, which not only consumes a lot of manpower but also has low work efficiency.

[0007] As a further preferred embodiment of this technical solution, multiple sets of positioning frames are slidably connected to the mounting frame. The mounting frame is provided with two sets of symmetrically distributed bidirectional lead screws.

[0011] This utility model provides a seed sorting device for agricultural planting, which has the following beneficial effects:

[0012] (1) This utility model uses a mounting frame, springs, and cams to screen mixed seeds in multiple sets of sieve racks, completing the classification and sorting of seeds, accelerating the work progress and saving manpower. The mixed seeds are placed in the uppermost sieve rack. The motor in the mounting base is started to drive the drive rod to rotate. Under the action of the first synchronous belt and the first synchronous wheel, the two sets of cams rotate synchronously. When the cams rotate, they intermittently push the stop block. The stop block drives the mounting frame to slide on the slide rod and stretches and compresses the spring. With the elastic potential energy of the spring, the mounting frame swings left and right in the mounting base, completing the screening of mixed seeds on the sieve rack. The sieve racks have different hole sizes, from large to small from top to bottom. Seeds of different sizes are left at different heights. Not only is manual screening not required, but screening of multiple types of seeds can be completed at one time, improving work efficiency.

Under the limiting action of the mounting frame, the two sets of connecting frames at both ends slide synchronously inward or outward. With the help of the connecting rods arranged in a cross pattern between the adjacent two sets of connecting frames, the equidistant adjustment between the multiple sets of positioning frames is achieved, so as to facilitate the installation of screening racks of different models and to facilitate the installation of different numbers of screening racks according to the actual number of seed types to be sorted.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 and Figure 2As shown in this embodiment, a seed sorting device for agricultural planting includes a mounting base 1, a mounting frame 2 on the mounting base 1, and two sets of symmetrically distributed sliding rods 6 on the mounting base 1. The mounting frame 2 is slidably connected to the mounting base 1, and the mounting frame 2 is slidably sleeved with the sliding rods 6. A spring 7 is provided on the sliding rod 6, and the two ends of the spring 7 are fixedly connected to the mounting frame 2 and the mounting base 1, respectively. Two sets of symmetrically distributed stops 14 are provided on the mounting frame 2, and two sets of symmetrically distributed cams 8 are provided on the mounting base 1. The two sets of cams 8 are respectively connected to the stops 14. Correspondingly, the cam 8 fits against the stop block 14. The mounting frame 2 is provided with multiple sets of equidistantly distributed positioning frames 12. The positioning frames 12 are provided with a screening frame 13. The cam 8 is rotatably connected to the mounting base 1 through a rotating shaft. The mounting base 1 is provided with a drive rod 9. The two ends of the drive rod 9 pass through the mounting base 1 and are rotatably connected to the mounting base 1. Both the drive rod 9 and the cam 8 are provided with a first synchronous pulley 10. The mounting base 1 is provided with two sets of symmetrically distributed first synchronous belts 11. The first synchronous belts 11 are respectively connected to the two sets of first synchronous pulleys 10 for transmission.

[0021] The installation frame 2, in conjunction with springs 7 and cams 8, enables the sieving of mixed seeds within multiple sets of sieve racks 13, completing the classification and sorting of seeds, accelerating the work progress while saving manpower. The mixed seeds are placed uniformly in the uppermost sieve rack 13. The motor within the installation base 1 drives the drive rod 9 to rotate. Under the action of the first synchronous belt 11 and the first synchronous wheel 10, the two sets of cams 8 rotate synchronously. As the cams 8 rotate, they intermittently push the stop block 14, causing the stop block 14 to slide the installation frame 2 on the slide rod 6, stretching and compressing the spring 7. Combined with the elastic potential energy of the spring 7, the installation frame 2 sways left and right within the installation base 1, completing the sieving of the mixed seeds on the sieve rack 13. The multiple sieve racks 13 have different aperture sizes, decreasing from top to bottom, leaving seeds of different sizes at different heights. This eliminates the need for manual sieving and allows for the sieving of multiple types of seeds in one operation, improving work efficiency.

[0022] like Figure 3 and Figure 4As shown, multiple sets of positioning frames 12 are slidably connected to the mounting frame 2. The mounting frame 2 contains two sets of symmetrically distributed bidirectional lead screws 15. A second synchronous pulley 16 is sleeved on the upper end of each set of bidirectional lead screws 15. A second synchronous belt 17 is also provided within the mounting frame 2, and the second synchronous belt 17 is connected to the two sets of second synchronous pulleys 16 respectively. Two sets of cross-distributed connecting rods 18 are provided between adjacent sets of positioning frames 12. The two ends of the two sets of bidirectional lead screws 15 pass through the mounting frame 2 and are rotatably connected to the mounting frame 2 via bearings. The two ends of the two sets of bidirectional lead screws 15 pass through the two sets of positioning frames 12 located at both ends and are connected to the mounting frame 2. The positioning frame 12 is threaded, and a first slider 19 is rotatably installed between the two sets of connecting rods 18. The first slider 19 is slidably connected to the mounting frame 2. A second slider 20 is rotatably installed at both ends of the two sets of connecting rods 18. The second slider 20 is slidably connected to the corresponding positioning frame 12. The mounting base 1 is provided with two sets of symmetrically distributed mounting rods 3. Both sets of mounting rods 3 are rotatably connected to the mounting base 1. Two sets of symmetrically distributed transmission wheels 4 are sleeved on both sets of mounting rods 3. The mounting base 1 is provided with a transmission belt 5. The transmission belt 5 is connected to the two sets of transmission wheels 4. The transmission belt 5 is located below the mounting frame 2.

[0023] The spacing between the multiple sets of positioning frames 12, along with the bidirectional lead screws 15 and connecting rods 18, can be adjusted, allowing staff to freely assemble different numbers and specifications of screening racks 13 according to the seed sorting requirements. The motor drives the bidirectional lead screws 15 to rotate, and the two sets of bidirectional lead screws 15 rotate synchronously under the action of the second synchronous belt 17 and the second synchronous wheel 16. Under the limiting action of the mounting frame 2, the two sets of connecting frames at both ends slide synchronously inward or outward. With the help of the connecting rods 18 arranged in a cross pattern between the adjacent sets of connecting frames, the equidistant adjustment between the multiple sets of positioning frames 12 can be achieved, so as to install different models of screening racks 13 and allow staff to install different numbers of screening racks 13 according to the actual number of seed types to be sorted.

[0024] This utility model provides a seed sorting device for agricultural planting. The specific working principle is as follows: Mixed seeds are uniformly placed in the uppermost sieve rack 13. The motor inside the mounting base 1 is started, driving the drive rod 9 to rotate. Under the action of the first synchronous belt 11 and the first synchronous wheel 10, two sets of cams 8 rotate synchronously. When the cams 8 rotate, they intermittently push the stop block 14. The stop block 14 causes the mounting frame 2 to slide on the slide rod 6, stretching and compressing the spring 7. Combined with the elastic potential energy of the spring 7, the mounting frame 2 sways left and right within the mounting base 1, completing the sieving of the mixed seeds on the sieve rack 13. The sieve racks 13 have different aperture sizes, decreasing from top to bottom. The seeds are left at different heights, eliminating the need for manual sieving and allowing for the sieving of multiple types of seeds at once, thus improving work efficiency. The motor drives the rotation of the bidirectional lead screw 15, and the two sets of bidirectional lead screws 15 rotate synchronously under the action of the second synchronous belt 17 and the second synchronous wheel 16. Under the limiting action of the mounting frame 2, the two sets of connecting frames at both ends slide synchronously inward or outward. With the help of the connecting rods 18 arranged in a cross pattern between the two sets of adjacent connecting frames, the equidistant adjustment between multiple sets of positioning frames 12 is achieved, which facilitates the installation of different models of screening racks 13 and allows workers to install different numbers of screening racks 13 according to the actual number of types of seeds to be sorted.
