[0029] A fixing rod 4 is fixedly connected to the inner side of the upper end of the housing 5. A through hole is opened in the center of the fixing rod 4. A fixing rod 12 is fixedly connected to the inner side of the lower end of the housing 5. A through hole is also opened in the center of the inner side of the fixing rod 12. The through holes of fixing rod 4 and fixing rod 12 are the same size. Bearings are fixedly connected inside fixing rod 4 and fixing rod 2. The bearings are the same size, and the holes of fixing rod 1 and fixing rod 2 are perpendicular to each other.

[0030] The bearings fixedly connected to the through holes of the first fixed rod 4 and the second fixed rod 12 are rotatably connected to the transmission rod 24. The outer side of the transmission rod 24 is fixedly connected to the spiral blade 11.

[0034] Both motor 1 and motor 2 are electrically connected to an external power source.

[0035] Working principle: During use, material is poured into the feed hopper, and motor 1 is started. Motor 1 drives the round rod 3 to rotate, which in turn drives the transmission rod 24, simultaneously rotating the spiral blades 11. The rotation of the spiral blades 11 accelerates the material transfer efficiency within the feed hopper. The material passes through the gap of the fixed rod 12 and continues to move downwards, reaching the baffle 13. By adjusting the handle, the channel is opened and closed. The material continues downwards to the baffle 21, where motor 8 is started, driving the round rod 20 to rotate synchronously. The rotation of the round rod 20 drives the gear 17 to rotate synchronously. Under meshing action, the gear 17 drives the gear guide rail 18 to move back and forth. The back and forth movement of the gear guide rail 18 causes the slider 19 to move in the limiting groove 1. The slider 19 slides within the groove of the partition plate. The sliding of the slider 19 drives the connecting rod 22 to move synchronously, thereby driving the second baffle 21 to move downward. The gear guide rail 18 continues to move backward, driving the second baffle 21 to continue to move backward. When the gear guide rail 18 moves to the last position, the second baffle 21 also reaches the outermost edge of the housing 5. At this time, the second motor 8 rotates in the opposite direction, driving the gear guide rail 18 to move forward. The gear guide rail 18 drives the second baffle 21 to move forward. When the rolling guide rail 18 moves to the foremost position, the second baffle 21 just reaches the leftmost edge of the housing 5, achieving a fully closed state. Thus, by adjusting the speed of the second motor 8, the opening and closing of the second baffle 21 can be changed, thereby achieving the effect of controlling the quantitative amount of material through the intermittent structure.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
