An outlet with the same specifications as the material discharge port 15 is opened on the walking frame 1. The blocking baffle 162 is movably connected at the outlet. A slide plate 18 is fixedly connected to the bottom of the walking frame 1. The blocking baffle 162 is slidably connected to the slide plate 18. The slide plate 18 can improve the stability of the lateral movement of the blocking baffle 162 and improve the pressure resistance at the same time.

[0034] When it is necessary to control the discharge of solid medicines, the telescopic device 161 can be used to drive the blocking baffle 162 to move horizontally, and the blocking baffle 162 can be used to adjust the opening degree of the opening, that is, to control the discharge amount. In this way, the solid medicines in the solid medicine box 4 can fall onto the distributing plate 12 through the discharge port 15 and the outlet in turn. The shaft rod 9 is used to give the distributing plate 12 rotational properties, so that the solid medicines can be effectively dispersed outward and fall onto the loose soil.
