[0002] Existing fertilizer spreaders have complex transmission methods, which can easily lead to unstable transmission during the transmission process and poor flexibility. Users cannot use them well in small areas and cannot control the machine well in complex terrain environments.

[0003] At present, when small sites need to spread fertilizer, the fertilizer spreader generally used is manually pushed forward, which leads to high labor intensity for workers and is prone to uneven and unstable fertilizer spreading effects.

[0004] When used in complex sites, the complex transmission method will lead to increased fuel consumption, and the uneven ground may easily lead to the risk of tipping;

[0005] To this end, our company has developed a "fertilizer spreader" that can be flexibly operated and used safely. Utility Model Content

By arranging the opening and closing mechanism 52 at the discharge port 431, the opening and closing mechanism 52 controls the amount of fertilizer spread. The control mechanism 53 is disposed at the front end of the frame 1, thereby facilitating flexible operation by the user.

[0061] The control mechanism 53 includes a wrench 531, a holding member 532, and a lifting rod 533. The wrench 531 is rotatably connected to the holding member 532. The holding member 532 is provided with a holding hole. The wrench 531 is clamped in the holding hole, and the wrench 531 is connected to the lifting rod 533. The rotating rod 1 54 is provided with a connecting member 1 541 and a connecting member 2 542. The connecting member 1 541 and the connecting member 2 542 are staggered. The lifting rod 533 is rotatably connected to the connecting member 1 541, and one end of the push-pull rod 51 is rotatably connected to the connecting member 2 542. The opening and closing mechanism 52 includes a limiting member 1 521 and a limiting member 2 522. The limiting member 1 An opening and closing door 523 is rotatably arranged between 521 and the limit member 2 522, and racks are arranged on the limit member 1 521, the limit member 2 522 and the opening and closing door 523, and the racks are engaged, and the limit member 1 521, the limit member 2 522 are connected to the rotating rod 2 55, and the limit member 1 521 and the limit member 2 522 are located on both sides of the discharge port 431; a connecting member 3 551 is arranged on the rotating rod 2 55, and the connecting member 3 551 is rotatably connected to the other end of the push-pull rod 51; a pull wire is arranged on the lifting rod 533, and the pull wire is connected to the clutch in the gearbox 22; preferably, the connecting member 2 542 and the connecting member 3 551 are parallel. By rotating the wrench 531, the wrench 531 is engaged with the holding hole on the holding member 532, so that the wrench 531 drives the lifting rod 533 to move upward or downward, thereby causing the lifting rod 533 to drive the rotating rod 1 54 to rotate. The connecting member 1 541 and the connecting member 2 542 are staggered, so that the lifting rod 533 pulls the connecting member 1 541 to rotate a certain angle, so that the connecting member 2 542 pushes the push-pull rod 51 to move; the fertilizer on both sides of the discharge port 431 is limited by the limiting member 1 521 and the limiting member 2 522, so that the fertilizer flows out from between the limiting member 1 521 and the limiting member 2 522, and the opening and closing door 523 is engaged with the limiting member 1 521 and the limiting member 2 522. This prevents the fertilizer from splashing outside the fertilizer spreading plate and allows the fertilizer to flow out evenly. By moving the push-pull rod 51, the rotating rod 2 55 is rotated, and the limit member 1 521, the limit member 2 522 and the opening and closing door 523 are rotated to a certain angle, thereby controlling the size of the discharge port 431; the pull line on the lifting rod 533 is connected to the clutch in the gearbox 22, thereby controlling the operation of the fertilizer transmission mechanism while controlling the size of the discharge port 431. When the discharge port is closed, the fertilizer transmission mechanism stops operating. The connecting member 3 551 on the rotating rod 2 55 is arranged in parallel with the connecting member 2 542, so that the control mechanism 53 can drive the rotating rod 1 54 and the rotating rod 2 55 to rotate at the same angle.

The throttle control mechanism 23 and the throttle amplification mechanism 24 are provided on the armrest 11; the control mechanism 53 is provided on the armrest 11. By providing the second traveling mechanism 12 and the armrest 11 at the front end of the frame 1, the stability of the fertilizer spreader during travel can be increased. By providing the throttle control mechanism 23, the throttle amplification mechanism 24, and the control mechanism 53 on the armrest 11, user operation is facilitated, danger is avoided, and the fertilizer is evenly spread.
