[0002] Fixed-point fertilization, also known as positioning fertilization or precision fertilization, is an efficient and accurate fertilization method in modern agriculture. It applies fertilizer to a specific location based on the distribution characteristics of crop roots and the actual nutrient requirements of crops to improve fertilizer utilization, reduce waste, and promote crop growth and yield.

In the initial state, the lifting cylinder is fully extended, and the hook frame and the fertilizer spreader are in the highest position; the present invention uses the tree-touching switch to touch the tree to realize intelligent fertilization, and its structure is simpler, the accuracy of fixed-point fertilization is high, and the failure rate is low, which can effectively reduce the production input cost of the fertilizer spreader and improve the reliability and practicality of the fertilizer spreader. Fixed-point fertilization is achieved through the extension and retraction of the tree-touching switch and the lifting cylinder, and quantitative fertilization is achieved through the intermittent rotation of the hopper.

When the reciprocating motor 34 rotates, it drives the worm 38 to rotate, the worm 38 drives the worm wheel 37 to rotate, and the worm wheel 37 drives the mounting plate 32, the swing arm 31 and the fertilizing assembly 2 to swing, so that the fertilizing assembly 2 swings in space.

[0052] When the steering gear 26 rotates, it drives the driving gear 25 to rotate, and the driving gear 25 drives the driven gear 24, the round block 215, the round tube 23, the intermediate tube 22 and the fertilizer joint tube 21 to rotate, the round block 215 drives the rotating shaft 213 to rotate, the rotating shaft 213 drives the rotating disk 221 to rotate, the rotating disk 221 drives the round rod shaft 220 to swing, the round rod shaft 220 drives the L-shaped rod 219 to swing, the L-shaped rod 219 drives the mounting block 218 to move, and the mounting block 218 drives the blocking plate 217 to move.

Each of the wheel frames 44 is respectively bearing-connected to symmetrical auxiliary wheels 45. Each of the auxiliary wheels 45 respectively contacts the corresponding track of the smart chassis 41.

[0054] The workflow of this embodiment is:

[0055] When the smart chassis 41 encounters a protrusion such as a stone, the track is deformed, driving the auxiliary wheel 45 to move, the auxiliary wheel 45 drives the wheel frame 44 to swing, the wheel frame 44 drives the V-shaped rod 43 to swing, and the V-shaped rod 43 drives the retaining spring 42 to move. After leaving the protrusion, the retaining spring 42 is restored to make the track contact the road surface.

[0056] The device uses the adjustment component 3 to lift the fertilization component 2 and separate the fertilization components 2 on both sides. The motor 36 is used to lift the fertilization component to the next point where fertilization is required and then lower it for precise fertilization. The reciprocating motor 34 and the worm gear meshing are used to separate the fertilization components 2 on both sides and adjust the left and right positions.

[0057] In the device, water enters the mixing tube 27 from the water joint pipes 210 on both sides, and fertilizer enters the mixing tube 27 from the upper fertilizer joint pipe 21. The structure is more reasonable. Water rushes in from both sides to mix the particles falling from the top, and they fall together from the lower discharge pipe 28 without being deposited in the mixing bin. Both sides are evenly stressed and mixed. The granular fertilizer and water are mixed and pressurized to be rushed in more accurately. The fertilizer and water are mixed synchronously into the soil for better contact and better absorption effect. The size of the opening of the water inlet pipes on both sides is synchronously adjusted with the channel for the granular fertilizer to enter, so as to accurately apply more fertilizer to places that need more fertilizer and less fertilizer to places that need less fertilizer.
