Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeder experiments, and in particular to a single-seed seeder test bench. Background Technology
[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a specific type or crop are often named after the crop, such as grain row seeders, corn hill seeders, cotton seeders, and hay spreaders. Currently, in agricultural hand-push seeders, the seeding wheel and rollers are in contact with the ground, and then the operator holds the frame forward, causing the rollers to rotate and thus propelling the machine forward. Simultaneously, the seeding wheel rotates as it moves forward, scattering the seeds onto the ground.
[0003] However, during the research and development or quality inspection of agricultural push-type seeders, in order to know the distance between the seeds in real time, researchers need to manually push the seeder to conduct seeding distance tests. However, the indoor testing site is flat and it is difficult to simulate a real seeding field. In addition, the soil moisture after rain will also have a certain impact on the pushing and walking of the seeder. Therefore, in the actual testing process, there are drawbacks such as wasting manpower in manual experiments and inaccurate test results. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of the existing technology as described in the background section, and to propose a single-seed planter test bench.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A single-seed seeder test bench includes a test bench and a soil layer disposed on the upper part of the test bench, and a seeder body. A side plate is fixedly connected to one side of the test bench, and a water tank is fixedly connected to the outer side of the side plate. A threaded rod is rotatably connected to the other side of the side plate, and a limit rod is fixedly connected to the other side of the side plate below the threaded rod. Nozzles communicating with the water tank are evenly arranged at the bottom of the limit rod. A movable block is slidably installed on the outer side of the limit rod, and the movable block is threaded onto the outer side of the threaded rod. A telescopic rod is fixedly connected to the bottom of the movable block, and a handle rod that engages with the telescopic rod is fixedly connected to the upper end of the seeder body.
[0007] Preferably, the outer side of the test bench is marked with graduation marks, and a humidity sensor is also provided on the outer side of the test bench.
[0008] Preferably, a pump body is fixedly installed on the upper end of the water tank, and the inlet and outlet ends of the pump body are respectively connected to the water tank and the limiting rod through pipes. A switch group consisting of multiple sets of switches is also provided on the outside of the water tank.
[0009] Preferably, a limiting plate is rotatably connected to the outer end of the threaded rod, and the limiting plate is fixedly connected to the outer end of the limiting rod. A motor that drives the threaded rod to rotate is fixedly connected to the outer side of the side plate.
[0010] Preferably, the telescopic rod is designed to move up and down, with an opening at the bottom of the telescopic rod communicating with the inner cavity, and a connecting sleeve rotatably connected to the bottom of the telescopic rod via a bearing. A limit block is fixedly connected to the inner wall of the opening at the bottom of the telescopic rod.
[0011] Preferably, a baffle is fixedly sleeved on the outer side of the handle bar and abuts against the bottom of the connecting sleeve. The surface of the upper part of the handle bar located on the baffle is provided with a smooth surface and a threaded surface from top to bottom. The threaded surface on the outer side of the handle bar is threadedly connected to the connecting sleeve. The surface of the upper part of the handle bar located on the baffle is also provided with a limiting groove in the longitudinal direction, and the limiting block is engaged in the limiting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention simulates the actual sowing environment of a single-seeder by laying a soil layer on the top of the test bench. A portable mounting structure allows the seeder to be installed at the lower end of a telescopic rod on the bottom of a movable block. Driven by a motor and transmission, the seeder moves to simulate actual sowing operations, allowing for the monitoring of the distance between sown seeds. The operation is simple, convenient, and labor-saving.

[0023] Reference Figure 1-4 A single-seed seeder test bench includes a test bench 1 and a soil layer 2 set on the upper end of the test bench 1, and a seeder body 3. A side plate 4 is fixedly connected to one side of the test bench 1, and a water tank 5 is fixedly connected to the outside of the side plate 4. A threaded rod 6 is rotatably connected to the other side of the side plate 4, and a limit rod 7 is fixedly connected to the other side of the side plate 4 below the threaded rod 6. Nozzles 8 communicating with the water tank 5 are evenly arranged at the bottom of the limit rod 7. A movable block 9 is slidably installed on the outside of the limit rod 7, and the movable block 9 is threaded on the outside of the threaded rod 6. A telescopic rod 10 is fixedly connected to the bottom of the movable block 9, and a handle 11 that is connected to the telescopic rod 10 is fixedly connected to the upper end of the seeder body 3.
[0024] The test bench 1 has a scale mark 101 on its outer side and a humidity sensor is also installed on its outer side. A pump body 501 is fixedly installed on the upper end of the water tank 5, and the inlet and outlet ends of the pump body 501 are connected to the water tank 5 and the limiting rod 7 respectively through pipes 502. A switch group 503 consisting of multiple sets of switches is also installed on the outer side of the water tank 5. A limiting plate 601 is rotatably connected to the outer end of the threaded rod 6, and the limiting plate 601 is fixedly connected to the outer end of the limiting rod 7. A motor 602 that drives the threaded rod 6 to rotate is fixedly connected to the outer side of the side plate 4. The telescopic rod 10 is designed to move up and down. A connecting point is provided at the bottom of the telescopic rod 10. The inner cavity has an opening, and the bottom of the telescopic rod 10 is rotatably connected to the connecting sleeve 1001 via a bearing. The inner wall of the opening at the bottom of the telescopic rod 10 is fixedly connected to the limiting block 1002. The outer side of the handle 11 is fixedly fitted with a baffle 1101 that abuts against the bottom of the connecting sleeve 1001. The surface of the handle 11 located at the upper end of the baffle 1101 is provided with a smooth surface and a threaded surface from top to bottom. The threaded surface on the outer side of the handle 11 is threadedly connected to the connecting sleeve 1001. The surface of the handle 11 located at the upper end of the baffle 1101 is also longitudinally provided with a limiting groove 1102, and the limiting block 1002 is engaged in the limiting groove 1102.
[0025] Based on the above structure, when using this device, the operator moves the seeder body 1 to the upper part of the soil layer 2 on the upper part of the test platform 1, and connects the handle 11 at the upper part of the seeder body 3 to the opening at the bottom of the telescopic rod 10. The limiting groove 1102 on the outer side of the handle 11 connects to the limiting block 1002 on the inner wall of the opening. Then, the smooth surface at the upper end of the handle 11 is pre-inserted into the connecting sleeve 1001 at the bottom of the opening and then extends to the bottom of the telescopic rod 10. Then, the connecting sleeve 1001 connects to the threaded surface on the outer wall of the handle 11 and rotates. At this time, the limiting groove 1102 and the limiting block 1002 are engaged and limited. At this time, the telescopic rod 10 extends and descends and the connection between the telescopic rod 10 and the handle 11 is locked by the thread of the above structure until the baffle 1101 abuts against the bottom of the connecting sleeve 1001. Subsequently, the motor 602 is started by the switch in the switch group 503. The motor 602 drives the threaded rod 6 to rotate, and the threaded rod 6 drives the movable block 9 to slide and move along the limit rod 7. The movable block 9 drives the telescopic rod 10 at the bottom, as well as the connected handle rod 11 and the seeder body 3 to move. Thus, the seeder body 3 moves on the upper part of the soil layer 2 to sow seeds without manual pushing. The distance between seeds during movement can be monitored by the scale 101 on the outside of the test bench 1. Based on this, considering that the soil may affect the movement of the seeder body 3 after rain, the operator can start the body 501 through the switch group 503 to draw water from the water tank 5, which is then sprayed out from the nozzle 8 at the bottom of the limit rod 7 to wet the soil. The humidity is monitored by the humidity sensor, and then the seeder body 3 continues to move on the wetted soil layer 2 for the test, making the test results more realistic and accurate.
