One end of the buckle is rotatably connected to the left and right sides of the upper connecting part or the lower connecting part. The second positioning protrusion is arranged on the left and right sides of the upper connecting part or the lower connecting part.

[0007] Further, the second positioning protrusion is in a cylindrical structure, which is perpendicular to the end face of the two sides of the upper connecting part or the lower connecting part.

[0008] Further, the executing mechanism comprises a gear shaft, a rolling wheel and a brush. The gear shaft is arranged in the through hole in the middle of the connecting part. The rolling wheel is arranged on the outer side wall of the gear shaft. One end of the brush is fixed to the outer side wall of the rolling wheel. The other end of the brush is in contact with the inner cavity wall of the connecting part.

[0009] Further, the outer side wall of the gear shaft is provided with a plurality of limiting protrusions at intervals in the circumferential direction, the limiting protrusions extend along the axial direction of the gear shaft, the roller center is provided with a mounting hole, and the inner side wall of the mounting hole is provided with a corresponding limiting through slot.

[0010] Further, the gear shaft is provided with an oil seal at both ends.

[0011] Further, the inner side wall of the lower connecting part is inclined.

[0012] Further, the upper box body and the upper connecting part, and the lower box body and the lower connecting part are integrated structures.

[0013] Further, the upper side of the upper box body is provided with an opening, the front side and the rear side of the lower box body are both provided with a first connecting opening and a second connecting opening, and the first connecting opening and the second connecting opening are connected with the fertilization pipeline and the fan through the connecting pipes, respectively.

[0014] Further, the upper wall above the inner side of the second connecting opening of the lower box body is inclined, and the end of the inclined surface close to the second connecting opening is a high point.

[0015] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0016] Through the combination of the first mortise and tenon structure and the second mortise and tenon structure, the firm connection between the upper connecting part and the lower connecting part is realized. The horizontal transverse arrangement of the first mortise and tenon structure increases the stability of the connection, and the buckle design of the second mortise and tenon structure provides additional fixing effect, so that the overall structure is more stable and reliable.

[0017] The combination of the gear shaft, the roller and the brush is adopted for the actuating mechanism, the rotation of the gear shaft drives the movement of the roller and the brush, thereby effectively and quantitatively conveying the granular fertilizer from the upper half of the shell to the lower half. This design not only improves the conveying efficiency, but also reduces the loss of granular fertilizer during the conveying process.

[0018] The combination of the limiting protrusions of the outer side wall of the gear shaft and the limiting through slot in the mounting hole of the roller ensures the stable rotation of the roller on the gear shaft, avoids the shaking and deviation of the roller during the conveying process, and improves the overall stability and durability.

[0019] The oil seals arranged at both ends of the gear shaft effectively prevent the entry of impurities such as lubricating oil or dust, ensure the normal operation of the actuating mechanism and prolong the service life.

[0020] The inner side wall of the lower connecting part is designed as an inclined surface, which helps the smooth sliding and accumulation of granular fertilizer, improves the uniformity and efficiency of fertilization. At the same time, the integrated structure of the upper box body and the upper connecting part, and the lower box body and the lower connecting part also enhances the stability and aesthetics of the whole.

[0021] The opening on the upper side of the upper box and the first and second connecting openings on the front and rear sides of the lower box are connected to the fertilizer pipeline and the blower through connecting pipes, respectively. This design allows the fertilizer rolling box to be easily connected to the entire fertilizer system to realize automated fertilizer operation.

[0022] The upper wall of the lower box located inside the second connection opening is designed as a slope, and the end of the slope near the second connection opening is the highest point. This design helps the airflow generated by the fan to enter the box more smoothly, improving the fertilization effect. On the other hand, it can increase the wind pressure and reduce the entry height of the wind, thereby preventing the granular fertilizer from being blown away. Attached Figure Description
