Description

Technical Field

[0001] This utility model relates to the field of corn sampling technology, and in particular to an automatic clamping corn seed sampling device. Background Technology

[0002] Maize variety testing is a crucial step in crop genetic improvement. Through multi-stage screening and evaluation of genetic characteristics and kinship, it ensures stable genetic quality. In maize breeding research and agricultural production testing, it serves as the core basis for judging variety characteristics, yield potential, and quality. Grain sampling, as an important step in variety testing, directly affects the accuracy of the testing data and is of great significance for subsequent genetic improvement directions and agricultural production variety selection decisions, providing key technical support for the high-quality and efficient development of the maize industry.

[0003] Traditional corn seed sampling mainly relies on manual operation. Staff need to manually hold the corn cob and then use tools such as tweezers and blades to remove some kernels as samples. However, staff can easily experience hand fatigue from holding the corn cob manually for a long time, resulting in high labor intensity. To address this issue, we propose an automatic clamping corn seed sampler. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5In this utility model, an automatic clamping corn seed sampling device includes a base 1. A housing 4 is fixedly connected to the upper surface of the base 1. A rotary motor 18 is fixedly installed on the right side of the housing 4. A threaded rod 19 is rotatably connected to the inner wall of the housing 4 via a bearing. The threaded rod 19 has symmetrical threads. The output end of the rotary motor 18 is connected to the right end of the threaded rod 19 via a bearing. Symmetrical movable seats 20 are threadedly connected to the outer surface of the threaded rod 19. The bottom surfaces of the two movable seats 20 are slidably connected to the upper surface of the base 1. Clamping plates 21 are fixedly connected to the front of the two movable seats 20. Arc-shaped grooves are opened on the side of the two clamping plates 21 that are close to each other. The front of the two clamping plates 21 penetrates the housing 4 and extends to the outside of the housing 4. A storage compartment 15 is fixedly connected to the upper surface of the base 1. A lifting block 16 is slidably connected inside the storage compartment 15. A lifting block 16 is fixedly installed on the inner bottom wall of the storage compartment 15. An electric push rod 17 is provided, the output end of which is connected to the bottom surface of the lifting block 16. A support frame 8 is fixedly connected to the upper surface of the lifting block 16, and a lighting lamp 12 is slidably connected to the outer surface of the support frame 8. A symmetrical positioning port 5 is provided on the upper surface of the base 1. The first collection component 2 and the second collection component 3 are respectively provided inside the two positioning ports 5. Through the cooperation of the rotary motor 18, the threaded rod 19, the movable seat 20 and the clamping plate 21, the rotary motor 18 drives the threaded rod 19 to rotate, which can make the two movable seats 20 move closer or further apart, thereby clamping or releasing the corn ears and realizing automated clamping work. The electric push rod 17 in the storage compartment 15 pushes the lifting block 16 to move up and down, which can realize the height adjustment of the lighting lamp 12. The horizontal position of the lighting lamp 12 can be adjusted by sliding the adjustment seat 9 on the support frame 8, which improves the practicality of the device.

[0022] The first collection component 2 includes a sample chamber 201 and a first positioning block 202. The bottom surface of the sample chamber 201 is connected to the upper surface of the first positioning block 202. The interior of one of the positioning ports 5 is slidably connected to the outer surface of the first positioning block 202. By setting the sample chamber 201, a sample of peeled corn kernels can be placed into the sample chamber 201. By inserting the first positioning block 202 into the positioning port 5, the sample chamber 201 can be installed onto the base 1.

[0023] The second collection component 3 includes an impurity bin 301 and a second positioning block 302. The bottom surface of the impurity bin 301 is connected to the upper surface of the second positioning block 302, and the interior of another positioning port 5 is slidably connected to the outer surface of the second positioning block 302. By setting the impurity bin 301, corn scraps and defective kernels can be put into the impurity bin 301. By inserting the second positioning block 302 into the positioning port 5, the impurity bin 301 can be installed on the base 1.

[0024] The outer surface of the storage compartment 15 is provided with symmetrical limiting ports 6. The interior of each limiting port 6 is slidably connected to a limiting block 7. The side of each limiting block 7 that is close to the other is connected to the outer surface of the lifting block 16. The lifting block 16 drives the limiting block 7 to slide within the limiting port 6, which can limit the lifting block 16 and prevent it from leaving the storage compartment 15.

[0025] The bottom surface of the base 1 is fixedly connected with symmetrical support legs 13. The bottom surfaces of both sets of support legs 13 are fixedly connected with suction cups 14. Through the cooperation of the support legs 13 and suction cups 14, the suction cups 14 can be tightly attached to the worktable, which improves the stability of the device and prevents the device from shifting.

[0026] The adjusting seat 9 has a threaded connection with a fastening bolt 10. The bottom surface of the fastening bolt 10 is in close contact with the upper surface of the support frame 8. By tightening the fastening bolt 10, the fastening bolt 10 is made to fit tightly against the support frame 8, thereby positioning the adjusting seat 9.

[0027] Both clamps 21 are L-shaped, and rubber pads 11 are fixedly connected to the sides of the two clamps 21 that are close to each other. By setting the rubber pads 11, the two rubber pads 11 clamp the ear of fruit, which can avoid damaging the ear of fruit.

[0028] The working principle of this utility model is as follows: In use, first start the rotary motor 18. The output end of the rotary motor 18 drives the threaded rod 19 to rotate through the bearing. The rotating threaded rod 19 drives the movable seat 20 to move closer to each other along the upper surface of the base 1. At the same time, the clamping plate 21 drives the rubber pad 11 to clamp the fruit ears. By starting the electric push rod 17, the output end of the electric push rod 17 pushes the lifting block 16 to move up and down in the storage compartment 15, thereby adjusting the height of the lighting lamp 12. By pushing the adjusting seat 9 to slide on the support frame 8, the level of the lighting lamp 12 is adjusted. Then, the fastening bolt 10 is tightened to fix the adjusting seat 9 to ensure clear light in the sampling area.
