The threaded screw 7 is threadedly connected to the positioning frame 6, and the lower end of the threaded screw 7 passes through the positioning plate 5, and the bottom end of the threaded screw 7 is rotatably connected to the movable frame 4; the forward direction of the pepper sowing equipment is positioned as the front of the device; the equipment frame 1 can be supported by the roller 2, and the furrowing plow 3 is used to furrow the ground when the sowing equipment moves forward to facilitate subsequent sowing. In order to adapt to the sowing of different varieties of peppers, the height of the furrowing plow 3 can be adjusted, and the movable frame 4 and the furrowing plow 3 are driven to rise and fall by rotating the threaded screw 7 to change the depth of the furrowing, and the cooperation between the movable frame 4 and the positioning frame 6 can improve the stability of the furrowing plow 3.

[0030] A material unloading mechanism is arranged in the middle of the equipment frame 1, and the material unloading mechanism comprises a material storage box 8, a material unloading pipe 9, a first rotating rod 10 and a material limiting plate 11. The material limiting plate 11 is designed in a fan-shaped structure. The material storage box 8 is symmetrically installed at the upper end of the middle of the equipment frame 1, and the lower end of the material storage box 8 is conductively connected with the material unloading pipe 9; the middle of the material unloading pipe 9 is designed in a circular structure, and the material unloading pipe 9 is rotatably connected with the first rotating rod 10, the material limiting plate 11 is fixedly connected with the outer wall of the first rotating rod 10, and the material limiting plates 11 are distributed in a ring array with the center of the first rotating rod 10 as the axis, and the end of the material limiting plate 11 is in contact with the inner wall of the circular part of the material unloading pipe 9; a transmission mechanism is arranged inside the material unloading pipe 9 The movable plate 12 is fixed to the middle of the limiting plate 11, the inner wall of the upper end of the storage box 8 is connected with a twisted rod 16, and the lower end of the twisted rod 16 is threadedly connected with a movable rotating rod 13, the outer wall of the lower end of the movable rotating rod 13 is connected with a stirring frame 14, and the stirring frame 14 is distributed in a ring array, the upper end of the movable rotating rod 13 is rotatably connected with a positioning plate, and a reset spring 15 is fixed to the upper end of the positioning plate, and the top of the reset spring 15 is connected to the inner wall of the storage box 8; the outer wall of the transmission plate 12 is provided with a limiting groove 17, and the limiting groove 17 is distributed in a ring array with the first rotating rod 10 as the center, the lower end of the movable rotating rod 13 is spherical, and the movable rotating rod 13 is spherical. The lower end of the rotating rod 13 is in contact with the limiting groove 17; the pepper seeds are stored through the storage box 8 and are discharged in cooperation with the feeding tube 9. When the first rotating rod 10 rotates, it can drive multiple groups of limiting plates 11 and the transmission disk 12 to rotate. The two adjacent groups of limiting plates 11 can accurately control the feeding amount of the pepper seeds. After the seeds are discharged between the two groups of limiting plates 11, because the limiting plates 11 are fan-shaped, the limiting plates 11 can only discharge again after rotating a certain angle, which takes a certain amount of time, thereby achieving the effect of intermittent feeding, and the feeding speed is controlled by the rotation speed of the first rotating rod 10; the limiting groove 17 is used to communicate with the movable rotating rod 13 and the reset spring 15. With the cooperation of the twisted rod 16, the limit groove 17 is used to drive the movable rotating rod 13 to reciprocate and rise and fall when the transmission disk 12 rotates. Because the twisted rod 16 cannot rotate, the relative position of the movable rotating rod 13 with the twisted rod 16 changes when the movable rotating rod 13 is lifted and lowered, thereby driving the movable rotating rod 13 to rotate. The design of the rotational connection between the positioning disk and the movable rotating rod 13 can avoid the interference of the return spring 15 when the movable rotating rod 13 rotates. When the movable rotating rod 13 drives the stirring frame 14 to rotate, the material inside the storage box 8 can be stirred.
