[0029] There are two material throwing discs 51, which are symmetrical on both sides of the center line of the bottom wall of the material spreading box 5.

[0030] There are two sets of material tapping plates 52, with four material tapping plates 52 in each set. The four material tapping plates 52 are evenly distributed on the top of the material throwing plate 51.

[0031] The material blocking assembly includes side baffles 6 disposed on both sides of the material spreading box 5. Top shells 61 are fixed on both sides of the top of the material spreading box 5. Gear 62 is disposed inside the top shell 61. Gear 62 is located directly above the rotating shaft at the top of the side baffle 6 and is fixedly connected to the rotating shaft at the top of the side baffle 6. Gear 63 meshes with one side of gear 62. A handwheel 64 is fixedly attached to the center of the top of gear 63, which protrudes from the top of the top shell 61.

[0032] Gear 2 63 has side shells 65 on both sides, which are fixed to the outer side wall of top shell 61. A pull plate 66 is provided at one end of the side shell 65. Blocks 67 are provided on both sides inside the top shell 61. Blocks 67 are locked between the teeth on both sides of gear 2 63. A connecting rod 68 is provided inside the side shell 65.

[0033] One end of the spring 69 is fixedly connected to the stop block 67, and the other end of the spring 69 is fixedly connected to the inner wall of the side shell 65.

[0034] Working principle:

[0035] After the fertilizer is fed into the fertilizer hopper 2, the motor 22 is started, and its power output drives the spiral material roller 21 to rotate. The spiral material roller 21 physically disperses the fertilizer through continuous stirring, which can effectively avoid the problem of subsequent conveying channel blockage caused by fertilizer agglomeration, and provide a uniformly dispersed material base for subsequent fertilizer spreading operations.

[0036] The fertilizer, after being broken down, falls naturally from the fertilizer hopper 2 into the discharge pipe 3. At this time, the motor 2 32 starts and drives the distribution roller 31 to rotate. The material plate on the outer periphery of the distribution roller 31 periodically pushes the fertilizer into the connecting pipe 4 in a certain amount. The fertilizer is then transported through the connecting pipe 4 to the spreading box 5 and finally falls onto the throwing plate 51.

[0037] The motor 53 inside the spreading box 5 provides power, which drives the throwing disc 51 and the patting plate 52 to rotate. When the fertilizer falls onto the rotating throwing disc 51, it is pushed outward by centrifugal force, and with the assistance of the patting plate 52, the fertilizer is efficiently spread to the surrounding area, completing the fertilizer spreading operation.

[0038] The feed inlet of the feed box 5 is only open at the front. Its side walls and the side baffles 6 on both sides form a blocking structure, preventing fertilizer from being spread out of the closed area. Fertilizer can only be spread out from the front opening. The opening angle of the side baffles 6 directly determines the fertilizer spreading area: the larger the outward opening angle of the side baffles 6, the wider the fertilizer coverage area; the smaller the inward opening angle, the more concentrated the fertilizer spreading area. It can be flexibly adjusted according to actual operational needs.

[0039] Specific adjustment steps:

[0040] Unlocking adjustment: Pull the outer plate 66, and the connecting rod 68 will drive the stop block 67 to move synchronously, so that the stop block 67 will disengage from the tooth gaps on both sides of the gear 63. At this time, the spring 69 will be compressed due to the force.

[0041] Angle adjustment: Turn the handwheel 64, which drives the second gear 63 to rotate. The second gear 63 meshes with the first gear 62, and through gear transmission, drives the rotating shaft of the side baffle 6 to rotate, realizing the outward or inward movement of the side baffle 6 until it is adjusted to the required angle.

[0042] Fixed adjustment angle: Stop turning handwheel 64, loosen pull plate 66, the compressed spring 69 releases its elasticity, pushes the stop block 67 to re-engage in the tooth gaps on both sides of gear 2 63, forming a mechanical lock on gear 2 63 to prevent it from rotating on its own, thus completing the fixing of the side baffle 6 angle and ending the adjustment operation.
