[0034] Working principle of the present invention:

[0035] First, the fertilizer is put into the storage box 2, and then the land preparation machine body 1 is driven to move by the tractor. When the land preparation machine body 1 moves, the connecting shaft 313 is driven to rotate by the driving shaft, so that the connecting shaft 313 drives the driving wheel 312 fixedly connected thereto to rotate. When the driving wheel 312 rotates, it drives the driven wheel 310 to rotate through the belt 311, so that the driven wheel 310 drives the fixed shaft 39 fixedly connected thereto to rotate. When the fixed shaft 39 rotates, it drives the bidirectional screw 35 fixedly connected thereto to rotate, so that the bidirectional screw 35 drives the threaded sleeve 34 threadedly connected thereto to move back and forth. When the threaded sleeve 34 moves, it drives the shaking frame 33 fixedly connected thereto to move synchronously, so that the shaking frame 33 shakes out the fertilizer in its inner cavity to avoid fertilizer agglomeration, which reduces the use effect of the device.

[0036] When the shaking frame 33 moves, it will drive the connecting rope to move synchronously, so that the connecting rope drives the winding wheel 411 fixedly connected thereto to rotate. When the winding wheel 411 rotates, it will drive the vertical rod 410 fixedly connected thereto to rotate, so that the vertical rod 410 drives the driving gear 412 fixedly connected thereto to rotate. When the driving gear 412 rotates, it will drive the driven gear 413 meshed with it to rotate, so that the driven gear 413 drives the connecting rod 47 fixedly connected thereto to rotate. When the connecting rod 47 rotates, it will drive the cam 48 fixedly connected thereto to rotate. When the protruding end of the cam 48 is in contact with the connecting frame 4 5, the cam 48 will push the connecting frame 45 upward, so that the connecting frame 45 drives the movable rod 44 fixedly connected thereto to move upward. When the movable rod 44 moves, it will drive the limit plate 43 fixedly connected thereto to move synchronously, so that the limit plate 43 stretches the spring 42 fixedly connected thereto. When the protruding end of the cam 48 is out of contact with the connecting frame 45, the movable rod 44 will drive the connecting frame 45 downward due to the elastic force of the spring 42, so that the connecting frame 45 continues to move up and down. When the connecting frame 45 moves up and down, the filtration effect of the fertilizer is accelerated, thereby improving the use effect of the device.

[0037] When the vertical rod 410 rotates, it drives the residual gear 711 fixedly connected to it to rotate, so that the residual gear 711 intermittently meshes with the full gear 710. When the residual gear 711 meshes with the full gear 710, it drives the full gear 710 to drive the linkage rod 79 fixedly connected to it to rotate, so that the linkage rod 79 drives the driving wheel 2 712 fixedly connected to it to rotate. When the driving wheel 2 712 rotates, it drives the driven wheel 2 714 to rotate through the belt 2 713, so that the driven wheel 2 714 drives the installation shaft 71 fixedly connected to it to rotate. When the installation shaft 71 rotates, it drives the bidirectional screw 2 72 fixedly connected to it to rotate, so that the bidirectional screw 2 72 drives the threaded sleeve 2 73 threadedly connected to it to move back and forth. When the threaded sleeve 2 73 moves, it drives the valve plate 6 to open and then close through the hinged rod 1 74, so that the fertilizer in the inner cavity of the storage box 2 is intermittently released into the soil, avoiding the waste of fertilizer caused by continuous fertilizer release.
