[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Specifically, a lead screw 320 rotates at the top of the hopper 200. The rotation of the lead screw 320 causes the pressure plate 340 to move downwards and compress the material inside the hopper 200, thereby bringing the top of the material inside the hopper 200 to a level state. By observing the scale values on the outside of the hopper 200, the amount of material quantitatively fed into the hopper 200 can be accurately determined. When the material inside the hopper 200 is conveyed out through the conveying pipe 400, the pressure plate 340 can continue to rotate downwards along the lead screw 320. At this time, the displacement sensor 341 inside the pressure plate 340 can record the distance the pressure plate 340 moves downwards during the conveying process of the conveying pipe 400, thus making it convenient for users to know the amount of material conveyed by the screw conveyor leaving the hopper 200, and facilitating the measurement of the amount of material conveyed by the screw conveyor within a certain period of time.

Material can be fed into the hopper 200 through the gap between the pressure plate 340 and the open end of the hopper 200. After the material is fed into the hopper 200, the pressure plate 340 is lowered to flatten the top surface of the material inside the hopper 200. The scale on the outside of the transparent plate 220 of the hopper 200 can be observed to know the amount of material inside the hopper 200. As the amount of material inside the hopper 200 decreases, the scale corresponding to the top surface of the material inside the hopper 200 can be observed again to facilitate the measurement of the amount of material consumed inside the hopper 200 within a certain conveying time.
[0037] like Figure 1As shown, in this embodiment, the top of the mobile base 100 is fixed with a speed reducer motor 130 capable of driving the shaft 410 to rotate, the bottom of the hopper 200 is fixedly connected with a discharge pipe 210, the discharge pipe 210 is fixedly connected with the feeding pipe 400, the speed reducer motor 130 drives the shaft 410 to rotate with the spiral blade, which facilitates the upward conveying of the material falling from the discharge pipe 210 into the feeding pipe 400 along the feeding pipe 400.

[0039] As shown, Figure 2 and Figure 3 in this embodiment, the bottom end of the lead screw 320 is fixed with a connecting shaft 350, a plurality of stirring paddles 351 are fixed at equal intervals on the outer side of the connecting shaft 350, and in the rotating process of the lead screw 320, the lead screw 320 drives the connecting shaft 350 to rotate, and the stirring paddles 351 on the outer side of the connecting shaft 350 rotate in the discharge pipe 210, which facilitates the smooth downward movement of the material and prevents the material from being blocked.
[0040] As shown, Figure 2 in this embodiment, the mobile base 100 further comprises a circular base plate, a plurality of cross beams are uniformly fixed on the circumferential side of the circular base plate, universal wheels are installed and fixed at the bottom of one end of the cross beam, and the universal wheels facilitate the movement of the spiral material conveying equipment to the material conveying station.
[0041] In Embodiment Two, on the basis of Embodiment One, in order to enable the feeding pipe 400 to convey material to equipment of different heights, and to prevent dust raising during discharging to some extent.
