[0039] Working principle: When the test platform is activated, the seeder 1 is connected to the fixing mechanism 2, the fixing mechanism 2 lifts the seeder 1 to a specified height, the vibration mechanism 6 is moved to the bottom of the seeder 1 and contacts the ground wheel of the seeder 1, and then the seeder 1 is tested. The angle adjustment mechanism 7 is used to tilt the fixed platform 9 to a specified angle, and the support mechanism 8 is displaced with the fixed platform 9. The seeder 1 is tested by simulating the ground with the vibration mechanism 6, the sand spreading mechanism 3 is started to prevent the seeds from moving, the conveying mechanism 4 is opened to recycle the seeds and sand, and the screening mechanism 5 is used to separate the seeds and sand, which are reused after separation to avoid waste.

[0040] When the fixing mechanism 2 lifts the seeder 1 to a specified height, the hydraulic telescopic rod 203 is started, and the output end of the hydraulic telescopic rod 203 drives the traction frame 205 to move up and down, and the traction frame 205 drives the fixed arm 202 to move up and down. The pitch angle rod 201 can adjust the pitch angle of the seeder 1 to adjust the contact area between the seeder 1 and the vibration mechanism 6. The fixed arm 202 and the pitch angle rod 201 drive the seeder 1 to move up and down. After the seeder 1 reaches the specified height, the hydraulic telescopic rod 203 is closed.

[0041] When the angle adjustment mechanism 7 is needed to adjust the fixed platform 9 to a specified angle, the angle motor 701 is started, and the output end of the angle motor 701 drives the worm 702 to rotate, and the worm 702 is meshed with the worm wheel 703, and the rotation of the worm 702 drives the worm wheel 703 to rotate, and the rotation of the worm wheel 703 drives the angle shaft 704 to rotate, and the rotation of the angle shaft 704 drives the angle gear 706 to rotate, and the angle gear 706 is meshed with the angle rack 707, and the rotation of the angle gear 706 drives the angle rack 707 to deflect, and the angle rack 707 deflects and slides on one side of the base 10, and the displacement of the angle rack 707 drives the fixed platform 9 to tilt, so that the fixed platform 9 is tilted. After the fixed platform 9 is tilted to the specified angle, the angle motor 701 is turned off. When the fixed platform 9 needs to be restored to the horizontal level, the angle motor 701 is started to reverse. The output end of the angle motor 701 drives the worm 702 to rotate in the opposite direction. The worm 702 is meshed with the worm wheel 703. The reverse rotation of the worm 702 drives the worm wheel 703 to rotate in the opposite direction. The reverse rotation of the worm wheel 703 drives the angle shaft 704 to rotate in the opposite direction. The reverse rotation of the angle shaft 704 drives the angle gear 706 to rotate in the opposite direction. The angle gear 706 is meshed with the angle rack 707. The reverse rotation of the angle gear 706 pulls the angle rack 707 to reset. At this time, the fixed platform 9 is restored to the horizontal level.

[0042] When the support mechanism 8 moves with the fixed platform 9, the fixed platform 9 tilts to one side and pulls the connecting seat 801 on one side to move upward. The connecting seat 801 moves upward and pulls the supporting column 802 to move upward. The supporting column 802 moves upward and compresses the return spring 803. When the supporting column 802 moves upward, the inclined groove opened inside it pushes the walking block 805 to slide to the other side. The walking block 805 slides to the other side and pushes another supporting column 802 to move downward. The other two supporting columns 802 move downward and stretch the return spring 803. When the fixed platform 9 is tilted to a specified angle, the locking nut 811 is rotated, and the locking nut 811 rotates to drive the locking shaft 809 to slide outward, and the locking shaft 809 slides outward to pull the trigger block 808 to slide outward. Under the action of the inclined T-shaped slide groove, the trigger block 808 slides outward to pull the two sliding blocks 807 to move toward each other, and the two sliding blocks 807 move toward each other to compress the tension spring 812, and the two sliding blocks 807 move toward each other to push the two locking blocks 806 to move toward each other, and the locking blocks 806 and the walking blocks 805 move toward each other. The corresponding side surfaces are fixedly connected with a plurality of teeth. At this time, the teeth on the locking block 806 contact with the walking block 805 to lock the inclined position of the fixed platform 9. When the fixed platform 9 is reset, the locking nut 811 is rotated in the opposite direction. The locking nut 811 rotates in the opposite direction to drive the locking shaft 809 to slide inward.
