Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of seed coating smoothness testing technology, and more specifically, to a seed coating smoothness testing device. Background Technology

[0002] Seed coating is a pretreatment technique that involves wrapping a thin film containing pesticides, fertilizers, and growth regulators around the surface of seeds. This film protects seeds from pests and diseases, provides nutrients for seed germination and seedling growth, and improves seed physical properties, such as making the surface smoother, reducing adhesion and clogging during sowing, and increasing the efficiency of mechanical sowing. Furthermore, it reduces the amount of pesticides and fertilizers used in the field, making it more environmentally friendly. Simply put, seed coating is like adding a "protective + nutritious + smooth" outer layer to the seed, helping it germinate and grow better, and making sowing more convenient.

[0003] After coating, the seeds need to be tested for smoothness. If the smoothness is insufficient (rough surface or high stickiness), they are prone to sticking together to form "clumps" during sowing, or getting stuck in the pipes, seed outlets, and other parts of the seeder, resulting in uneven sowing (missed sowing, double sowing) and inconsistent sowing depth. Existing testing devices generally involve pouring the seeds into a test bucket, then opening the bottom of the bucket to allow the seeds to slide down. The smoothness of the seed coating is tested by calculating the sliding time. However, in this testing method, the direction of the test bucket is generally fixed. When testing on a certain slope, the angle of the test bucket is difficult to adjust, reducing the efficiency and effectiveness of the seed coating smoothness test. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a seed coating slip test device to solve the technical problem that the direction of the test barrel is generally fixed in the prior art, and the angle of the test barrel is difficult to adjust when testing is required under certain slope conditions, which reduces the efficiency and effectiveness of seed coating slip test.

[0005] At least one embodiment of this disclosure provides a seed coating smoothness testing device, including a base plate, a frame fixedly connected to the base plate, and further including: a test barrel, a sealing plate, and a receiving mechanism. The test barrel is disposed on one side of the frame via a rotating mechanism, which is used to drive the angle adjustment of the test barrel.

[0024] like Figures 1-4As shown, this invention discloses a seed coating smoothness testing device according to an embodiment of the present invention. The device includes a base plate 1, a frame 2 fixedly connected to the base plate 1, a test barrel 3, a sealing plate 4, and a receiving mechanism. The test barrel 3 is mounted on one side of the frame 2 via a rotating mechanism, which drives the angle adjustment of the test barrel 3. A groove is formed at the bottom of the test barrel 3, and the sealing plate 4 is positioned within the groove via a moving mechanism to seal the test barrel 3. The receiving mechanism is mounted on the base plate 1 to collect any slipping seeds. The rotating mechanism facilitates the rotation of the test barrel 3, thereby adjusting its tilt. The moving mechanism drives the sealing plate 4 to control the opening and closing of the bottom of the test barrel 3, and the receiving mechanism collects the tested seeds to prevent them from scattering. Compared to the prior art, this invention facilitates multi-angle adjustment of the test angle, improving the efficiency and effectiveness of seed coating smoothness testing.

[0025] The rotating mechanism includes: a rotating shaft 5, a fixed ring 6, a transmission assembly, and a limiting assembly. The rotating shaft 5 is rotatably connected to one side of the frame 2, the fixed ring 6 is fixedly connected to one end of the rotating shaft 5, and the test barrel 3 is fixedly connected inside the fixed ring 6. The transmission assembly is located on one side of the frame 2 and is used to drive the rotating shaft 5 and the fixed ring 6 to rotate. The limiting assembly is located on one side of the frame 2 and is used to limit the transmission assembly. The transmission assembly includes: a rotating gear 7, a rack 8, and a pusher frame 9. The rotating gear 7 is fixedly connected to the rotating shaft 5, the rack 8 is slidably connected to one side of the frame 2 through a sliding assembly, and the rack 8 meshes with the rotating gear 7. The pusher frame 9 is fixedly connected to the top of the rack 8. The limiting assembly includes: a fixed frame 10, a slide rod 11, and a rotating seat. 12. A limiting wheel 13 and a support spring 15 are provided. The fixed frame 10 is fixedly connected to one side of the frame 2. Two slide rods 11 are provided, and both slide rods 11 are slidably connected to the fixed frame 10. The rotating seat 12 is fixedly connected to one end of the two slide rods 11. The limiting wheel 13 is rotatably connected to the rotating seat 12. Multiple limiting grooves 14 are provided on the rack 8. The limiting wheel 13 contacts the inner wall of one of the limiting grooves 14. Support springs 15 are sleeved on both slide rods 11. The two ends of the two support springs 15 are fixedly connected to the fixed frame 10 and the rotating seat 12, respectively. The sliding assembly includes a moving groove 16 and a slider 17. The moving groove 16 is provided on the rack 8. The slider 17 is fixedly connected to one side of the frame 2 and slidably connected to the moving groove 16.

[0026] The operator presses down on the push frame 9 to move the rack 8 downwards. When the rack 8 moves downwards, it drives the rotating gear 7 and the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, it drives the fixed ring 6 and the test barrel 3 to swing, thereby adjusting the tilt angle of the test barrel 3. During the movement of the rack 8, the limiting wheel 13 rolls on the rack 8, thereby causing the limiting wheel 13 to disengage from one limiting groove 14 and roll into the next limiting groove 14. The supporting spring 15 set on the slide rod 11 supports the rotating seat 12 and the limiting wheel 13, thereby limiting the movement of the rack 8.

[0027] The moving mechanism includes a stabilizing frame 18 and a first electric cylinder 19. A connecting plate 24 is fixedly connected to one side of the sealing plate 4. The output end of the first electric cylinder 19 is fixedly connected to the connecting plate 24. The stabilizing frame 18 is fixedly connected to the test barrel 3. The first electric cylinder 19 is installed on the stabilizing frame 18. The output end of the first electric cylinder 19 passes through the stabilizing frame 18 and is fixedly connected to the sealing plate 4. The first electric cylinder 19 drives the connecting plate 24 and the sealing plate 4 to move in the slide groove, thereby opening the test barrel 3 and facilitating the seeds to slide into the test barrel 3.

[0028] The receiving mechanism includes a movable frame 20 and a receiving box 21. A handheld frame 25 is fixedly connected to the receiving box 21.

There are two guide rods 22, both of which are fixedly connected to the base plate 1. Two guide blocks 23 are slidably connected to each of the two guide rods 22. The top of each guide block 23 is fixedly connected to the movable frame 20. The position of the receiving box 21 is adjusted by moving the movable frame 20 on the guide rod 22, so that the receiving box 21 is aligned with the bottom of the test barrel 3 to receive the falling seeds.

[0029] Working principle: When testing the smoothness of seed coating, the seeds to be tested are poured into the test container 3. Then, the operator presses down on the pusher 9, causing the rack 8 to move downwards. As the rack 8 moves downwards, it drives the rotating gear 7 and the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 causes the fixing ring 6 and the test container 3 to swing, thereby adjusting the tilt angle of the test container 3. During the movement of the rack 8, the limiting wheel 13 rolls on the rack 8, causing the limiting wheel 13 to disengage from a limiting groove 14 and roll to... The next limiting groove 14 is used to support the rotating seat 12 and the limiting wheel 13 through the support spring 15 set on the slide rod 11, thereby limiting the movement of the rack 8. The first electric cylinder 19 drives the connecting plate 24 and the sealing plate 4 to move in the slide groove, thereby opening the test barrel 3 and facilitating the seeds to slide down into the test barrel 3. The moving frame 20 moves on the guide rod 22 to adjust the position of the receiving box 21, so that the receiving box 21 is aligned with the bottom of the test barrel 3 to receive the sliding seeds.
