After accumulating too much, the conveying efficiency will decrease, and it needs to be cleaned regularly, which is inconvenient. Using the embodiment of the present invention, the device is applied to the premise of the mixing station In the scene, first, add materials into the hopper 2, and the servo motor 3 is powered on and gradually driven. The servo motor 3 rotates to drive the central axis rod 4 to move, and the central axis rod 4 drives the spiral blade 5 to twist along the inside of the hopper 2. The spiral blade 5 is relatively flat in shape. After the extrusion effect of rapid rotation, the material inside the hopper 2 is gradually transmitted to the other side, and finally squeezed out through the discharge piece 6 to complete the transportation; in this process, the rotation of the spiral blade 5 drives the material to move, and the position of the material changes. When the spiral blade 5 moves, the material gradually contacts the conveying component, and the conveying component is squeezed by friction, and the conveying component swings due to the squeezing. When the conveying component swings, the conveyed material is moved, so as to prevent the material from being stuck in one place, so that each material passing through the conveying component can be assisted in processing, thereby improving the efficiency of transportation.

When the swing plate 23 moves, it contacts the outer wall of the spiral blade 5, and the spiral blade 5 rubs against the vertical rod 25 while rotating, so that the spiral blade 5 is gradually rubbed and cleaned, reducing the dirt adhering to the outer wall, and achieving the effect of direct wiping.

[0033] Combination Figures 5 and 6As shown, the anti-adhesion component includes a main rod 211 installed at the bottom end of the side strip 21, a chuck 212 is connected to the bottom end of the main rod 211, a support piece 213 is clamped on the top of the chuck 212, a torsion spring is arranged between the main rod 211 and the chuck 212, a plurality of hammer strips 214 are fixedly connected to the side of the support piece 213, the plurality of hammer strips 214 are made of rubber, the thickness of the chuck 212 is less than the thickness of the spiral leaf 5, and the angle between the main rod 211 and the chuck 212 is ninety degrees; the chuck 212 is an arc-shaped structure, the coverage area of ​​the support piece 213 is half of the width of the hopper 2, and the bottom end of the chuck 212 is slidably connected to the spiral leaf 5; when working, in the process of material being transmitted, the material gradually interacts with the spiral leaf 5, and the material is discharged When the material moves in the direction of the feeding member 6, the material is easy to form a blockage, and the blocked material will eventually be driven to the part between the discharging member 6 and the hopper 2. After the accumulation, it is not easy to handle evenly, which affects the transmission efficiency.

When it needs to be processed, the embodiment of the present invention is used, and the material is gradually transmitted to the inside of the cylinder ring 63. The material flowing into the cylinder ring 63 moves to the inside of the rotating drum 65, and the material is aligned with the upper part of the rotating drum 65. When the material enters the upper part of the rotating drum 65, due to the action of the instantaneous impact force, the rotating drum 65 and the push piece 66 will move. The rotating drum 65 will tilt during movement, and deflect after tilting, which accelerates the outward transportation of the material and reduces the blockage caused by slow transportation.

[0035] Working principle: During the material conveying process, due to frequent conveying, more stubborn stains are easily adhered to the outer wall of the spiral blade 5, and friction treatment is required when conveying. Using the embodiment of the present invention, the spiral blade 5 rotates after being energized, and the spiral blade 5 and the material are squeezed against each other, the position of the material changes, and the material hits the baffle 22 to move. The middle part of the baffle 22 is empty, and the material gradually hits the vertical rod 25. The vertical rod 25 is displaced by the impact, and the vertical rod 25 drives the swing plate 23 to move synchronously. The swing plate 23 is separated from the fitting position in the slide groove of the baffle 22, and the swing plate 23 forms a swinging tendency. The traction bar 27 buffers the swing plate 23, and the vertical rod 25 moves a certain distance. When the swing plate 23 moves, it contacts the outer wall of the spiral blade 5. The spiral blade 5 rotates and rubs against the vertical rod 25, so that the spiral blade 5 is gradually rubbed and cleaned, reducing the dirt adhering to the outer wall, and achieving the effect of direct wiping;

[0036] In the process of material transmission, the material gradually interacts with the spiral blade 5, and the material moves toward the discharge piece 6. The material is easy to form a blockage, and the blocked material will eventually be driven to the part between the discharge piece 6 and the hopper 2. After the accumulation, it is not easy to handle evenly, which affects the transmission efficiency. Using the embodiment of the present invention, when the material passes through the main rod 211, the material hits the chuck 212, and the chuck 212 is driven toward the direction of the in-and-out material 6. When the chuck 212 is driven, it deflects with the main rod 211 as the center of the circle. When the chuck 212 deflects, it drives the support piece 213 and the hammer bar 214 to deflect synchronously. The hammer bar 214 gradually rubs against the material, and the material is broken up. The broken material falls between the spiral blade 5 and the hopper 2, and the shape of the material is changed, thereby reducing the accumulation, preventing more blockages, improving the uniformity, and achieving the effect of auxiliary transportation;

[0037] Due to the frequent discharge of materials from the discharge piece 6, the materials are prone to blockage. When they need to be processed, the embodiment of the present invention is used, and the materials are gradually transmitted to the inside of the cylinder ring 63. The materials flowing into the cylinder ring 63 move to the inside of the rotating drum 65, and the materials are aligned with the upper part of the rotating drum 65. When the materials enter the upper part of the rotating drum 65, due to the action of the instantaneous impact force, the rotating drum 65 and the push piece 66 will move. The rotating drum 65 will tilt during movement, and deflect after tilting, which accelerates the outward transportation of the materials and reduces the blockage caused by slow transportation. At this time, the materials are in contact with the push piece 66, and the push piece 66 is deformed by the impact of the materials. The push piece 66 tilts toward the direction of the torsion seat 64, and the push piece 66 accelerates the pushing of the materials at the outlet, so that the materials can be more easily and quickly cleared out, which has the function of reducing blockage and improving the clearing effect.
