Description

Technical Field

[0001] The utility model relates to the technical field of screw conveyors, in particular to a feeding mechanism of a screw conveyor. Background Art

[0002] Screw conveyors are divided into two types in terms of conveying form: shaft screw conveyors and shaftless screw conveyors, and in terms of appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors. Shaft screw conveyors are suitable for non-sticky dry powder materials and small particle materials (for example: cement, fly ash, lime, grain, etc.), while shaftless screw conveyors are suitable for conveying sticky and easily entangled materials (for example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating spiral blades push the material to be conveyed by the screw conveyor. The force that prevents the material from rotating with the screw conveyor blades is the material's own weight and the friction resistance of the screw conveyor casing to the material.

[0003] In the material conveying of the screw conveyor, for the conveying of some dry powder materials, if the material clumps due to moisture and other reasons, the agglomerated material is easily accumulated and blocked in the screw conveyor after being fed into the screw conveyor, affecting the conveying of the screw conveyor and reducing the conveying efficiency of the screw conveyor.

[0024] like Figure 1 to Figure 3 As shown, an embodiment of the utility model proposes a screw conveyor feeding mechanism, comprising: a screw conveyor 1 and a hopper 2 connected and arranged at the top of the screw conveyor 1, two crushing rollers 3 are rotatably connected inside the hopper 2, a distance adjustment component 4 for driving the crushing rollers 3 to move is provided on one side of the hopper 2, a driven wheel 5 is fixed at one end of the two crushing rollers 3, a side plate 6 is provided on one side of the hopper 2 which can be lifted and lowered, two driving wheels 7 are rotatably connected on one side of the side plate 6, the two driving wheels 7 are respectively connected to the driven wheel 5 through belts 8, meshing gears 9 are fixed on one side of the two driving wheels 7, a first motor base 10 is fixed on one side of the side plate 6, a first drive motor 11 fixed to the driving wheel 7 is fixed on one side of the first motor base 10, and a lifting component 12 for driving the side plate 6 to move is provided on one side of the hopper 2.

[0025] In this embodiment, when feeding and conveying into the screw conveyor 1 through the hopper 2, the agglomerated materials are crushed with the cooperation of the crushing rollers 3, which facilitates the conveying of materials by the screw conveyor 1. When the distance adjustment component 4 moves, it drives the two crushing rollers 3 to move in the opposite direction to adjust the distance between the two crushing rollers 3. At the same time, under the movement of the lifting component 12, the side plate 6 is driven to move up and down, and the side plate 6 drives the driving wheel 7 to move up and down, adjusts the distance between the driving wheel 7 and the driven wheel 5, and makes the belt 8 in a straightened state, thereby facilitating the normal transmission between the driving wheel 7 and the driven wheel 5. Then, in the movement of the first drive motor 11, the two driving wheels 7 can be driven to rotate in the opposite direction with the meshing of the two gears 9. The two driving wheels 7 drive the two driven wheels 5 to rotate in the opposite direction, thereby driving the two crushing rollers 3 to rotate in the opposite direction, so that the crushing rollers 3 crush the agglomerated materials, thereby facilitating the adjustment of the roller spacing of the crushing rollers 3, and facilitating the crushing of materials of different sizes, thereby facilitating the feeding and conveying of the screw conveyor 1 and improving the conveying efficiency of the screw conveyor 1.

[0026] In a further embodiment, Figure 2 As shown, the distance adjustment component 4 includes first sliders 41 rotatably arranged on the outer walls of the two crushing rollers 3 respectively, first slide grooves 42 for the first sliders 41 to slide are provided on both sides of the hopper 2, and bidirectional screw rods 43 threadedly connected to the first sliders 41 are rotatably connected in the two first slide grooves 42, and sprocket wheels 44 are fixed at one end of the two bidirectional screw rods 43, and the two sprocket wheels 44 are connected by chains 45 for transmission, a second motor seat 46 is fixed on one side of the hopper 2, and a second driving motor 47 fixed to the sprocket wheel 44 is fixed on the top of the second motor seat 46, and the lifting component 12 includes a second slider 121 fixedly arranged on one side of the side plate 6, and a second slide groove 122 for the second slider 121 to slide is provided on one side of the hopper 2, and the second slide groove 122 is fixedly connected to the second slider 121 through an electric telescopic rod 123.

[0027] During the movement of the second driving motor 47, with the cooperation of the sprocket 44 and the chain 45, the two bidirectional screw rods 43 are driven to rotate synchronously. Since the thread directions of the two first sliders 41 located on the same bidirectional screw rod 43 are different, they can be driven to move in the opposite direction, thereby driving the two crushing rollers 3 to move in the opposite direction, adjusting the distance between the two crushing rollers 3, and facilitating the crushing of materials of different sizes. At the same time, under the movement of the electric telescopic rod 123, the second slider 121 is driven to move up and down, and the second slider 121 drives the side plate 6 to move up and down, and the side plate 6 drives the driving wheel 7 to move up and down, and adjusts the distance between the driving wheel 7 and the driven wheel 5, so that the belt 8 is always in a straightened state, thereby facilitating the normal transmission between the driving wheel 7 and the driven wheel 5, and facilitating the normal rotation of the crushing roller 3.

[0028] In a further preferred embodiment of the present invention, Figure 3As shown, a cross bar 13 located below the crushing roller 3 is provided in the hopper 2, the cross bar 13 is connected to the hopper 2 through an elastic component 14, a dredging rod 15 is fixed to the bottom end of the cross bar 13, a dredging plate 16 is fixed to the outer wall of the dredging rod 15, and the crushing roller 3 is provided with an impact component 17 that drives the cross bar 13 to move.

[0029] When the crushing roller 3 rotates, with the cooperation of the impact component 17, it drives the movement of the cross bar 13. At the same time, with the cooperation of the elastic component 14, the cross bar 13 can be driven to move up and down. The cross bar 13 drives the dredging rod 15 and the dredging plate 16 to move up and down, so as to dredge the materials accumulated in the hopper 2, avoid the accumulation and blockage of the materials, avoid affecting the feeding of the screw conveyor 1, and improve the feeding efficiency of the screw conveyor 1.

[0030] In a further embodiment, Figure 3 As shown, the elastic component 14 includes a third slider 141 fixedly arranged at both ends of the cross bar 13, and third slide grooves 142 for the third slider 141 to slide are provided on both sides of the inner wall of the hopper 2. The third slide groove 142 is fixedly connected to the third slider 141 through a spring 143. The impact component 17 includes a striker rod 171 fixedly arranged on the outer wall of the crushing roller 3, and a striker plate 172 that contacts the striker rod 171 is fixed at the top of the cross bar 13.

[0031] When the crushing roller 3 rotates, it drives the collision rod 171 to rotate, and the collision rod 171 hits the collision plate 172 during rotation. The collision plate 172 is in a rectangular shape, so that after the position of the crushing roller 3 is adjusted, it can still hit the collision plate 172. The collision plate 172 drives the movement of the cross bar 13 under the impact, and the cross bar 13 drives the movement of the third sliding block 141.
