[0001] The utility model relates to a corn seed screening device with a high germination rate, in particular to a corn seed screening device with a high germination rate. Background Art
[0002] Corn seeds are reproductive bodies that have the ability to grow into adult corn plants. They are formed by ovules through pollination and fertilization. Corn seeds are divided into four types: conventional seeds, inbred lines, single-cross seeds, double-cross seeds and triple-cross seeds. When producing corn seeds, corn seeds with full grains need to be selected for seed production and breeding to increase the germination rate of corn seeds after sowing.

DETAILED DESCRIPTION
[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.
[0026] Embodiment 1: A corn seed screening device with high germination rate, see Figure 1-Figure 4 , Figure 6 and Figure 8As shown, it includes a mounting frame 1, a screening barrel 2, a guide cover 3, a positioning frame 4 and a sorting net 18. The screening barrel 2 is installed on the mounting frame 1 by bolt connection. The sorting net 18 is slidably arranged in the screening barrel 2. The positioning frame 4 is fixedly connected to the top of the mounting frame 1 by welding. The guide cover 3 is installed on the positioning frame 4 by bolt connection. A discharge port 26 is opened on the left side of the screening barrel 2. An isolation cover 24 for covering the discharge port 26 is slidably arranged on the screening barrel 2. The guide cover 3 can be opened by sliding the isolation cover 24, and the impurities remaining on the sorting net 18 can be taken out from the discharge port 26. , it is convenient to clean the sorting net 18. The material guide cover 3 is funnel-shaped, which is convenient for feeding corn seeds. A dust cover 23 is slidably provided on the material guide cover 3. When the device is not in use, the dust cover 23 can be slid downward to cover the material guide cover 3. It also includes a cylinder 5, a connecting seat 6, a connecting rod 7 and a material blocking plate 8. The front side of the material guide cover 3 is installed with a cylinder 5 by bolt connection. A connecting seat 6 is fixedly connected to the telescopic rod of the cylinder 5. Connecting rods 7 are rotatably provided on the left and right sides of the connecting seat 6. Two material blocking plates 8 are slidably provided on the material guide cover 3, and the connecting rods 7 are rotatably connected to the front sides of adjacent material blocking plates 8 respectively.
[0027] When screening corn seeds, first pour the corn seeds into the material guide cover 3, then start the cylinder 5, shorten the telescopic rod of the cylinder 5, and drive the two material blocking plates 8 to slide outward through the connecting seat 6 and the connecting rod 7 to open the material guide cover 3, and the corn seeds fall onto the sorting net 18 through the gap between the two material blocking plates 8. The sorting net 18 screens out impurities in the corn seeds, so that the screened corn seeds fall downward to the lower part of the mounting frame 1 through the sorting net 18. After the material guide cover 3 is turned on for a period of time, the telescopic rod of the cylinder 5 is controlled to extend, so that the connecting seat 6 and the connecting rod 7 drive the two material blocking plates 8 to slide inward to close the material guide cover 3, thereby stopping the feeding of the corn seeds. When it is necessary to feed the corn seeds again, the telescopic rod of the cylinder 5 is shortened, so that the corn seeds can be fed in batches, so as to avoid clogging of the feed port and the screen when too many corn seeds are fed at one time, and prevent the progress of corn seed screening from being affected.
[0028] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 and Figure 5As shown, it also includes a material receiving box 9, a screening net 10, a double-axis motor 11, a first rotating shaft 12, a first cam 13 and a first pulley group 14. The material receiving box 9 is placed at the lower part of the mounting frame 1, and the screening net 10 is slidably arranged in the material receiving box 9. The double-axis motor 11 is installed on the right side of the lower part of the mounting frame 1. Three first rotating shafts 12 are rotatably arranged in the material receiving box 9. The output shaft on the left side of the double-axis motor 11 passes through the material receiving box 9 and is connected to one of the first rotating shafts 12 through a coupling. Three first cams 13 are fixedly connected to the first rotating shaft 12. The first cam 13 rotates and squeezes the screening net 10. The transmission is transmitted between two adjacent first rotating shafts 12 through the first pulley group 14. The first pulley group 14 consists of two pulleys and a flat belt. Pulleys are fixedly connected to the first rotating shaft 12 and the output shaft of the double-axis motor 11, and a flat belt is wound between the two pulleys.
[0029] When the corn seeds after screening fall down through the sorting net 18, the corn seeds fall on the screening net 10, and the double-axis motor 11 is started. One end of the output shaft of the double-axis motor 11 drives one of the first rotating shafts 12 to rotate, and multiple first rotating shafts 12 are driven through the first pulley group 14, so that the first rotating shaft 12 drives the first cam 13 to intermittently squeeze the screening net 10 to move up and down to perform secondary screening of the corn seeds, so that the shriveled corn seeds are screened out from the screening net 10, thereby further improving the germination rate of the corn seeds after sowing. After the screening is completed, the double-axis motor 11 is turned off.
[0030] See also Figure 1 and Figure 6 As shown, it also includes a second pulley group 15, a third pulley group 1501, a second rotating shaft 16 and a second cam 17. Two second rotating shafts 16 are rotatably arranged in the screening barrel 2. Four second cams 17 are fixedly connected to the second rotating shaft 16. The second cam 17 rotates to squeeze the sorting net 18 to slide up and down. The output shaft at the right end of the dual-axis motor 11 and the second rotating shaft 16 are transmitted through the second pulley group 15, and the transmission between two adjacent second rotating shafts 16 is transmitted through the third pulley group 1501. A protective cover 25 is fixedly connected to the mounting frame 1. The protective cover 25 covers the output shaft of the dual-axis motor 11 and one of the second rotating shafts 16. The protective cover 25 is used to protect the second pulley group 15 to prevent foreign matter from being involved in the second pulley group 15.
[0031] When the output shaft of the dual-axis motor 11 rotates, the other end of the output shaft of the dual-axis motor 11 drives one of the second rotating shafts 16 to rotate through the second pulley group 15, and the second rotating shaft 16 is transmitted through the third pulley group 1501, so that multiple second rotating shafts 16 drive the second cam 17 to rotate and squeeze the sorting net 18 to slide up and down, so that the corn seeds on the sorting net 18 shake up and down, thereby accelerating the screening of corn seeds and avoiding clogging of the sorting net 18.
[0032] See also Figure 7As shown, it also includes a handwheel 19, a screw 20, a guide rod 21 and a brush 22. The screw 20 runs through the left side of the material receiving box 9, and the handwheel 19 is fixedly connected to the rear end of the screw 20. The right side of the material receiving box 9 is fixedly connected to the guide rod 21 by welding. A brush 22 is slidably arranged on the guide rod 21. The brush 22 is made of nylon and the bottom of the brush 22 is in contact with the bottom of the material receiving box 9. The brush 22 is located below the screening net 10, and the brush 22 is threadedly connected to the screw 20.
[0033] After the shriveled corn seeds are screened out from the screening net 10, the shriveled corn seeds fall into the bottom of the receiving box 9. The hand wheel 19 is turned, and the hand wheel 19 drives the screw 20 to rotate, so that the screw 20 drives the brush 22 to slide along the guide rod 21 at the bottom of the receiving box 9, thereby brushing out the corn seeds, making it convenient to collect and process the shriveled corn seeds.
[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
