Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a block-shaped screw conveyor. Background Art

[0002] The screw conveyor conveys materials by pushing them through rotating spiral blades. The force that prevents the materials from rotating with the screw conveyor blades is the material's own weight and the friction resistance of the screw conveyor casing to the materials.

[0003] The conveying pipe in the screw conveyor is a circular structure and is used to convey powder materials and granular materials. However, when the screw conveyor conveys large-volume block materials, due to the large volume of the block materials, the spiral plate is very likely to get stuck or heat up, which in turn affects the conveying of the block materials; the conveying pipe is an integrated circular structure. When the screw conveyor needs maintenance, the conveying components in the screw conveyor need to be maintained or disassembled. However, the integrated structure of the conveying pipe makes it impossible for the operator to maintain the conveying components, which in turn affects the service life of the screw conveyor. Utility Model Content

[0004] The utility model aims to solve the problem that the screw conveyor in the prior art is very likely to get stuck when conveying bulk materials, and proposes a bulk screw conveyor.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figures 1-4 The block screw conveyor includes a base plate 1 with a moving wheel, and a conveying structure for conveying materials is provided on the base plate 1. The conveying structure consists of a frame 3, a feed hopper 4, a discharge port 5, a screw shaft 6, and a spiral plate 8.

[0022] A motor 2 is fixedly mounted on the base plate 1, and an output shaft which is transmission-connected to the screw shaft 6 is fixedly connected to the output end of the motor 2. The output shaft and the screw shaft 6 are horizontally arranged correspondingly, and a transmission belt 7 is connected between the output shaft and the screw shaft 6 through a coupling. When the motor 2 is energized, the output shaft is driven to rotate, and the output shaft drives the screw shaft 6 to rotate through the transmission belt 7. When the screw shaft 6 rotates, it drives the spiral plate 8 to transport the bulk material.

[0023] A U-shaped conveying trough corresponding to the spiral plate 8 is opened in the frame 3, and evenly distributed cover plates 9 are installed on the frame 3. The frame 3 is a U-shaped structure, and the cover plates 9 are horizontally arranged above the frame 3. Figure 3 As shown, the conveying area at the upper end of the U-shaped conveying trough is larger than the conveying space of the spiral plate 8, so that the block materials will not cause a clamping phenomenon on the spiral plate 8 when being conveyed in the U-shaped conveying trough, thereby ensuring the normal conveying of the block materials.

[0024] A clamp assembly for clamping the cover plate 9 is installed on the frame 3 .

[0025] The clamp assembly includes a placement groove 10 opened on the frame 3 and limiting the cover plate 9, and a connected positioning groove 11 is opened on the placement groove 10. Figure 3 As shown, by opening evenly distributed placement slots 10 on the frame 3, it is more convenient for the operator to lift the cover 9, and according to the position to be repaired, one of the cover plates 9 can be removed, so that the operator can check the maintenance position in time. A symmetrically arranged support plate 12 is fixedly installed in the cover plate 9, and a positioning rod 13 that penetrates the cover plate 9 and extends into the positioning slot 11 is slidably sleeved on the support plate 12. The support plate 12 guides the positioning rod 13, so that the positioning rod 13 can move smoothly into the positioning slot 11 when moving.

[0026] A moving assembly for driving the positioning rod 13 to move horizontally is installed in the cover plate 9 .

[0027] The moving assembly includes a bidirectional screw rod 14 rotatably installed in the frame 3, and two matching nuts 15 are slidingly sleeved on the bidirectional screw rod 14. A connecting rod 16 is connected between the positioning rod 13 and the two nuts 15. The support plate 12 guides the moving direction of the positioning rod 13, thereby limiting the moving direction of the nut 15.

[0028] The bidirectional screw rod 14 is arranged horizontally, and the two ends of the connecting rod 16 are respectively connected to the nut 15 and the positioning rod 13 pin. A handle extending to the outside of the cover plate 9 is fixedly installed on the bidirectional screw rod 14, and a locking bolt connected to the cover plate 9 is threaded on the handle. The cover plate 9 and the frame 3 are quickly connected by the reverse movement of the two positioning rods 13.

[0029] The functional principle of this utility model can be explained through the following operation modes:

[0030] The material enters the frame 3 through the feed hopper 4;

[0031] The output end of the motor 2 drives the output shaft to rotate. When the output shaft rotates, it drives the screw shaft 6 to rotate through the transmission belt 7. When the screw shaft 6 rotates, it drives the spiral plate 8 to transport the material.

[0032] When the material is being conveyed, the conveying area of ​​the upper end of the U-shaped conveying trough is larger than the spiral plate 8. When the material is pushed, the large block of material is squeezed and the material automatically moves to the upper end of the U-shaped conveying trough. Under the action of gravity, the material falls onto the spiral plate 8 for conveying and is discharged through the discharge port 5.

[0033] When it is necessary to maintain or repair the components in the frame 3;

[0034] Remove the locking bolt and pull the handle, which drives the bidirectional screw rod 14 to rotate. When the bidirectional screw rod 14 rotates, it drives the two nuts 15 to move toward or in opposite directions.

[0035] When the two nuts 15 move in opposite directions, the traction link 16 deflects. The position difference generated by the deflection of the link 16 can extract the positioning rod 13. When the positioning rod 13 slides on the support plate 12, it is disconnected from the positioning groove 11.

[0036] The cover plate 9 is manually lifted to disconnect the cover plate 9 from the placement groove 10 , and the operator performs maintenance on the components inside the frame 3 .

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
