Problems solved by technology

[0002] The airborne fertilizer applicator is installed on the agricultural machinery carrier (such as a tractor) through its bracket, and the bracket is equipped with a fertilizer bucket. The fertilizer outlet of the fertilizer bucket is equipped with a wheeled fertilization mechanism, and the wheeled fertilizer mechanism is equipped with a fertilizer wheel connected by rotation. The fertilizer wheel rotates through the power provided by the agricultural machinery carrier. In the past, sprockets or gears were fixed on the wheel shaft of the agricultural machinery carrier, and the wheel shaft transmitted its torque to the fertilizer wheel shaft of the fertilizer wheel through a chain mechanism or a gear set. The installation and debugging of the structure is relatively complicated, and the sprocket mechanism and the gear set are arranged at a low position on the wheel shaft, which is easy to be stuck by crops and weeds, and the work reliability is poor. Therefore, the prior art is to use the power shaft of the agricultural machinery One shaft) to drive the fertilizer wheel to rotate, but the power shaft of the agricultural machinery vehicle has a higher speed, while the speed of the fertilization wheel is slower. The torque transmission between the two, therefore, a face gear clutch mechanism is installed on the power shaft end of the agricultural machinery carrier, and the transmission and cutting of torque are realized through the meshing and separation of the two face gears in the face gear clutch mechanism, one of the face gears It is fixedly connected with the power shaft of the agricultural machinery carrier, and the other end face gear is fixedly connected with the power input shaft of the reduction mechanism in the circumferential direction and slidingly connected in the axial direction. The power output shaft of the reduction mechanism transmits the decelerated torque to the fertilization wheel through the commutator , in this structure, due to the high rotational speed of the power shaft of the agricultural machinery carrier, the two end gears in the end gear clutch mechanism will generate a large shock force at the moment of meshing, which will affect the service life of the entire mechanism. The strength requirements of each component are high, and the teeth of the end gear wear quickly and are prone to slippage; moreover, the installation of the end gear clutch mechanism and its matching reduction mechanism on the power output shaft requires additional design and installation. The matching bracket is used to support the end face gear clutch mechanism, deceleration mechanism and various accessories, and the types of commercially available agricultural machinery vehicles are various. Although the reliability of the work has been improved, the installation, layout and debugging work is still cumbersome and complicated.

Moreover, the brackets of the existing airborne fertilizer applicators are mostly equipped with left and right fertilizer buckets, which can simultaneously fertilize the ridges on both sides of the agricultural machinery carrier, thereby improving the efficiency of fertilization. The machine synchronously transmits the decelerated torque to the fertilizer wheel of the wheel-type fertilization mechanism in the two fertilizer hoppers. However, when fertilizing a single ridge, the simultaneous fertilization of the two fertilizer hoppers will cause waste of fertilizer. All the fertilizer in the fertilizer hopper on the fertilization side is filled into the fertilizer hopper on the fertilization side, but the cleaning operation increases manpower and affects the progress of fertilization
