When the moving block contacts the arc-shaped contact block, the moving block contacts the arc-shaped contact block. The arc-shaped contact block can push the arc-shaped push plate to squeeze the liquid storage cotton to replenish the nutrient solution, and the moving block pushes the arc-shaped moving rod to slide upward along the outer arc surface of the fixed arc rod, thereby driving the toggle rod to move, and the sheared branches and leaves are toggled up and down by the toggle rod, so that the pruned branches and leaves are easier to fall off, thereby realizing the pruning of the spherical plants while replenishing the nutrient solution, and at the same time, the pruned branches and leaves are toggled to make them fall to the ground, reducing the problem of branches and leaves getting stuck in the pruned branches, saving working time and improving work efficiency.

[0017] 4. The present invention sets a shaking mechanism. When the arc plate moves, it will drive the touching round block to move. The movement of the touching round block will push the hit round block to move downward. The hit round block drives the limit plate, the impact cylinder and the connecting short block to move downward. At this time, the elastic telescopic block is in an extended state. When the touching round block is not in contact with the hit round block, the elastic telescopic block can drive the connecting short block, the impact cylinder and the limiting plate to reset. When the impact cylinder is reset, it will hit the bottom of the arc plate, thereby reducing the excessive adhesion of soil at the bottom of the spherical plant to the inner side of the arc plate.

An end of the upper top plate of the bracket main body 1 is provided with a circular hole matching the telescopic end of the electric push rod 2. The electric push rod 2 is fixed on the top of the top plate of the bracket main body 1, and the telescopic end of the electric push rod 2 passes through the circular hole and is connected with the upper circular plate of the fixed frame 3; a driving member 4 is arranged inside the fixed frame 3. The driving member 4 is a driving motor, which is fixed between the upper circular plate and the lower circular plate of the fixed frame 3, and a shaft hole is opened on the lower circular plate; a turntable 5 located at the bottom of the fixed frame 3 and connected with the output shaft of the driving member 4 in a matching manner. The output shaft of the driving motor passes through the shaft hole on the lower circular plate and is connected with the turntable 5; an arc - shaped pruning mechanism 6 slidably arranged on the turntable 5 and used for pruning spherical plants. The arc - shaped pruning mechanism 6 is used to prune spherical plants into a spherical shape, and the arc - shaped pruning mechanism 6 can also prune spherical plants close to the wall; and a positioning mechanism 7 arranged on the bottom side wall of the bracket main body 1 and corresponding to the end of the arc - shaped pruning mechanism 6 and used for positioning spherical plants. The positioning mechanism 7 can not only position the bottom of the spherical plants to be pruned, but also supplement nutrient solution to the bottom branches of the spherical plants, and at the same time can also stir the cut branches and leaves, so that the cut branches and leaves fall to the ground, reducing the problem of branches and leaves getting stuck on the pruned branches, saving working time and improving work efficiency.

[0022] Specifically, a moving groove 51 is opened at the bottom of the turntable 5. The arc - shaped pruning mechanism 6 includes a moving column 61 slidably arranged in the moving groove 51. Limiting grooves are opened on both side walls of the moving groove 51. Limiting sliders (not shown in the figure) slidably matched with the limiting grooves are arranged on both sides of the top end of the moving column 61, so as to prevent the moving column 61 from falling downwards and ensure its position in the moving groove 51; a first spring 62 is arranged between one side of the moving column 61 and the inner side wall of the moving groove 51, a fixed arc rod 63 is arranged on the side of the moving column 61 far away from the first spring 62, and the radian of the fixed arc rod 63 matches the radian of the spherical plants to be pruned; a plurality of pruning knives 64 are arranged on the side of the fixed arc rod 63.

[0028] When the fixed arc rod 63 rotates, the moving block 77 at its end will contact the arc contact block 711, and then the moving block 77 will push the arc contact block 711 to slide inward along the first slide groove 751 on the arc plate 75, and then push the arc push plate 710 to squeeze the liquid storage cotton 79. The arrangement of multiple arc contact blocks 711 can squeeze the liquid storage cotton 79 multiple times, so that the nutrient solution adsorbed in the liquid storage cotton 79 is squeezed out and flows out from the holes on the arc orifice plate 78, so as to achieve pruning of the spherical plants while replenishing the nutrient solution to the roots of the spherical plants.
