  Although the self-propelled fertilizer spreader in the prior art can change the spraying direction and spraying angle, it is configured to spread and spread the fertilizer in a wide range, so that unnecessary waste is sprinkled. In recent years, the effects of residual components that have not been absorbed by crops due to overspraying on the groundwater and the impact on the environment due to the loss of excess fertilizers are becoming problems. Then, in this invention, the self-propelled fertilizer spreader which can perform the streak-like or strip-like dispersion which spreads a required quantity only to a required part is provided.

In order to solve the above-mentioned problems, a fertilizer hopper having a fertilizer stirring and feeding section for stirring and feeding fertilizer, and a fertilizer feed outlet for supplying the fertilizer in the fertilizer hopper to the spraying section and a fertilizer spreading amount at the bottom of the fertilizer hopper In the self-propelled fertilizer spreader having a shutter plate for adjusting the fertilizer delivery port and a fertilizer spreader below the fertilizer feed outlet, the fertilizer spreader has one end arranged at the lower part of the fertilizer feed outlet at the bottom of the fertilizer hopper. A belt conveyor is provided, and fertilizer can be dropped and sprayed from the other end , and this belt conveyor is configured as one, and a rotation fulcrum is provided near the lower part of the fertilizer feed port provided in the center of the machine travel direction. We propose a self-propelled fertilizer spreader characterized in that the conveyor is pivotable in the horizontal direction.
In addition, a fertilizer hopper having a fertilizer stirring and feeding section for stirring and feeding fertilizer, a fertilizer feed outlet for supplying the fertilizer in the fertilizer hopper to the spraying section, and a shutter plate for adjusting the amount of fertilizer sprayed at the bottom of the fertilizer hopper In the self-propelled fertilizer spreader provided with a fertilizer spreader below the fertilizer feed outlet, the fertilizer spreader is provided with a belt conveyor with one end arranged at the lower portion of the fertilizer feed at the bottom of the fertilizer hopper The fertilizer can be dropped and sprayed from the other end, and a pair of belt conveyors of the fertilizer spraying section are arranged substantially symmetrically in the body traveling direction and provided with a pair of fertilizer feed outlets at the bottom of the fertilizer hopper corresponding to the pair of belt conveyors. The present invention proposes a self-propelled fertilizer spreader characterized in that a belt conveyor is provided so as to be rotatable in the horizontal direction around the vicinity of the lower part of each fertilizer feed outlet.
Further, the self-propelled fertilizer spreader is characterized in that the shutter plate for adjusting the fertilizer application amount at the fertilizer feed outlet can be opened and closed independently at the left and right, and can be opened and closed simultaneously at the left and right. Suggest .

  By adopting the above configuration, the fertilizer sprayed from the end of the belt conveyor of the spraying section is sprayed in a streak or strip shape in the aircraft traveling direction, and a pair of belt conveyors are arranged symmetrically in the left-right direction in the aircraft traveling direction. When the fertilizer feed port is located in the vicinity of the lower fulcrum, it can be rotated in the horizontal direction and turned to both sides to form two streaks or streak spraying. be able to. In addition, by allowing the shutter plate for adjusting the fertilizer application amount at the fertilizer feed outlet to be opened and closed independently on the left and right sides, one-side application and both-side application can be easily selected.

  Moreover, the fertilizer spreader which can perform a streak-like or strip-like dispersion | distribution at lower cost can be provided by comprising a belt conveyor in one. By spreading the stripes or stripes in this way, the fertilizer can be sprayed only on necessary portions, so that the fertilizer is not sprayed wastefully and can be easily sprayed in large quantities locally.
