[0002] In order to ensure the manufacturing quality and qualified rate of mass-produced seeding devices and improve the research and development design level of new seeding devices, it is necessary to conduct random inspections of batch products and test bench performance tests on scientific research samples during the production and scientific research processes. In order to ensure that the seeds do not bounce when they fall on the seeding detection rotary belt assembly after being discharged from the seeding device, the current seeding test benches for seeding devices all adopt the method of applying butter on the surface of the seeding detection rotary belt, and at the same time use manual measurement to check the seed spacing. The above-mentioned prior art not only causes the test seeds to be contaminated with butter and cannot be used again, resulting in seed waste and increased test costs, but also the manual measuring ruler has technical problems such as low efficiency, poor accuracy, and inconvenient operation.

A primary seed recovery transfer trough with a seed cleaning plate is arranged on the stand at the lower part of the end of the seeding detection rotary belt assembly, and the seed cleaning plate is in contact with the friction material layer on the surface of the seeding detection rotary belt assembly. A baffle type seed conveyor belt assembly is installed on the side of the stand in an inclined and rotatable manner, and a secondary seed recovery transfer trough connected to a funnel type seed box is installed on the stand at the upper end of the baffle type seed conveyor belt assembly; electric motor C, electric motor B, and electric motor A are fixedly installed on the stand, and are respectively connected to the wheel axle, the drive shaft of the seeding detection rotary belt assembly, and the drive shaft of the baffle type seed conveyor belt assembly in turn, thereby forming a seed automatic recovery and recycling seeding test bench.

[0009] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. A seed automatic recycling and seeding test bench comprises a stand 1 and a seeding device 5. A funnel-type seed box 6 is installed on the upper end of the stand 1. A seeding drive shaft 3 and a wheel shaft 10 are supported and installed parallel to each other and rotatably at the middle part of the stand 1 and below the funnel-type seed box 6. A driving pulley 16 and a driven pulley 4 are fixed on the wheel shaft 10 and the seeding drive shaft 3 respectively. A transmission belt 18 is sleeved on the driving pulley 16 and the driven pulley 4. A seeding device 5 is installed on the stand 1 and is located at the lower side of the funnel-type seed box 6 and is connected to the seeding device 5. The seeding drive shaft 3 is plug-in connected and cooperated with the seeding device 5. A seeding detection rotary belt assembly 14 is rotatably installed on the lower side of the stand 1 and below the seeding device 5. A friction material layer is covered on the surface of the seeding detection rotary belt assembly 14. A flexible scale 15 is arranged on the surface of the seeding detection rotary belt assembly 14. A friction roller 2 is installed on the frame 1 at a position above the starting end of the seeding detection rotary belt assembly 14, and the friction roller 2 is in contact with the friction material layer on the surface of the seeding detection rotary belt assembly 14. A primary seed recovery transfer trough 11 with a seed cleaning plate 12 is arranged at a position below the end of the seeding detection rotary belt assembly 14 on the frame 1, and the seed cleaning plate 12 is in contact with the friction material layer on the surface of the seeding detection rotary belt assembly 14. A baffle-type seed conveyor belt assembly 8 is installed on the side of the frame 1 in an inclined and rotatable manner, and a secondary seed recovery transfer trough 7 connected to a funnel-type seed box 6 is installed on the frame 1 at the upper end of the baffle-type seed conveyor belt assembly 8; electric motor C17, electric motor B13, and electric motor A9 are fixedly installed on the frame 1, and are respectively connected to the wheel axle 10, the drive shaft of the seeding detection rotary belt assembly 14, and the drive shaft of the baffle-type seed conveyor belt assembly 8.

[0010] During the test, the electric motor C17 drives the seeding device 5 to plant seeds through the axle 10, the active pulley 16, the transmission belt 18, the driven pulley 4, and the seeding drive shaft 3. The electric motor B13 and the electric motor A9 respectively drive the seeding detection rotary belt assembly 14 and the baffle-type seed conveyor belt assembly 8 to perform rotary motion. At this time, the seeds in the funnel-type seed box 6 are filled into the cavity of the seeding device 5 and then discharged in sequence and fall on the surface of the friction material layer of the seeding detection rotary belt assembly 14. The friction between the friction roller 2 and the friction material layer causes the friction material layer to generate static electricity. While preventing the seeds from jumping, the seeds are firmly adsorbed on the seeding detection rotary belt assembly 14. The flexible ruler 15 is used to detect the seed spacing and whether there is any missed seeding or reseeding. The seeds after inspection are scraped off from the seeding inspection rotary belt assembly 14 by the seed cleaning plate 12, and flow back into the funnel-type seed box 6 through the first-level seed recovery transfer trough 11, the baffle-type seed conveyor belt assembly 8, and the second-level seed recovery transfer trough 7 in turn for continued use.
