Angle-adjustable support of shaftless screw conveyor

Abstract

The angle-adjustable support comprises a machine body and a spiral conveying roller rotationally connected to an inner cavity of the machine body, one end of the machine body is fixedly connected with a first motor, and a second motor drives a linkage block to rotate and drives the machine body to deflect at the same time, so that the angle of the machine body deflects. When the inner cavity of the machine body is blocked, the first motor can rapidly start a reverse rotation mode, and meanwhile the spiral conveying roller is driven to rotate in the opposite direction. And the stacked materials can be conveyed reversely, so that the materials are effectively prevented from being blocked in a feeding pipe valve area. In addition, the feeding pipe valve is arranged under the protruding portion of the machine body, so that materials can smoothly fall into the feeding pipe valve through the natural slope when being conveyed to the feeding pipe valve area, the probability of occurrence of the blocking condition is further reduced, and the operation efficiency and stability of equipment are improved.

Description

Technical Field

[0001] The utility model relates to the technical field of screw conveyors, in particular to an angle-adjustable bracket for a shaftless screw conveyor. Background Art

[0002] Screw conveyors use the rotation of the spiral blades on the screw shaft to transport materials forward. However, traditional screw conveyors use front and rear brackets to fix the casing, forming a fixed conveying angle, which means that the screw conveyor can only convey at a certain angle.

[0003] When faced with the need to change material conveying heights, the traditional approach is to replace the screw conveyor with one with a different casing angle, which significantly increases the overall conveying cost. Furthermore, the design limitations of traditional screw conveyors—the consistent orientation of the spiral blades—often lead to material accumulation at the conveying end, disrupting the smooth flow and normal processing of the material.

[0004] Therefore, we propose an angle-adjustable bracket for a shaftless screw conveyor to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to provide an angle-adjustable bracket for a shaftless screw conveyor to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: a shaftless screw conveyor angle-adjustable bracket, comprising a body and a spiral conveying roller rotatably connected to the body cavity, one end of the body being fixedly connected to a first motor, and an output end of the first motor passing through the body surface and fixedly connected to the spiral conveying roller, a discharge pipe valve being fixedly connected to the top of the body surface, a feed pipe valve being fixedly connected to the bottom of the body surface, and two sets of support legs being rotatably connected to the bottom of the body;

[0007] Two groups of linkage blocks are provided on the surface of the body, and support frames are provided on the outside of the linkage blocks. A rotating seat is fixedly connected between the linkage blocks and the support frames. A second motor is fixedly connected to the surface of one group of support frames, and the second motor passes through the support frame and the rotating seat in sequence and is fixedly connected to the linkage blocks.

[0008] Preferably, the supporting legs are hydraulic telescopic columns whose lengths can be adjusted arbitrarily, and the supporting legs and the bottom of the supporting frame are fixedly connected with rubber shock-absorbing seats.

[0009] Preferably, the surface of the linkage block is provided with a "("-shaped curvature that matches the curvature of the body surface.

[0010] Preferably, a protrusion is provided on the inner wall of the body, and the feed pipe valve is located directly below the protrusion.

[0011] Preferably, a protection block for limiting the rotation angle of the machine body is fixedly connected between the two groups of support frames.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The second motor rotates the linkage block while also rotating the machine body, shifting the angle and adjusting its height to match the changed height. If the machine's internal cavity becomes clogged, the first motor quickly activates reverse rotation, simultaneously driving the spiral conveyor roller in the opposite direction. This ensures that accumulated material can be transported in the reverse direction, effectively preventing clogging in the feed valve area. The feed valve is positioned directly below a raised portion of the machine body, allowing material to smoothly fall into the area using its natural slope. This further reduces the likelihood of blockage and improves the equipment's operating efficiency and stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-2 The present invention provides a technical solution: a shaftless screw conveyor with an adjustable angle, comprising a housing 1 and a spiral conveyor roller 2 rotatably connected to the inner cavity of the housing 1. A discharge pipe valve 4 precisely directs the material to be conveyed into the inner cavity of the housing 1. Subsequently, a first motor 3 is activated, driving the spiral conveyor roller 2 to rotate within the inner cavity of the housing 1. Through its spiral structure, the added material is smoothly conveyed to the area where the feed pipe valve 5 is located. Finally, the feed pipe valve 5 transfers the material to the outside, completing the entire conveying process.

[0019] For details, please refer to Figure 1-2When the material conveying height needs to be changed, the second motor 9 fixedly connected to the surface of the support frame 7 is started. The rotating seat 8 provides support for the linkage block 6 while ensuring that the linkage block 6 rotates. The second motor 9 drives the linkage block 6 to rotate while also driving the body 1 to deflect, causing the angle of the body 1 to shift, so that its height is adjusted to be consistent with the changed height. The protective block limits the rotation angle of the body 1, and the surface body 1 rotates too much and hits the ground, causing damage.

[0020] At this point, the discharge pipe valve 4 and the feed pipe valve 5 are ready for connection to external feed pipes, ensuring smooth material delivery. After completing the height adjustment, adjust the support legs 10 to ensure they, together with the rubber cushioning base 11, form a stable support system and remain level with the ground. Adjusting the length of the support legs 10 provides solid support for the entire device, ensuring its stability and safety.

[0021] For details, please refer to Figure 1-2 If the inner cavity of the machine body 1 becomes clogged, the first motor 3 quickly activates reverse rotation mode, simultaneously driving the spiral conveyor roller 2 in the opposite direction. This ensures that accumulated materials can be transported in the reverse direction, effectively preventing material blockage in the feed pipe valve 5 area. The feed pipe valve 5 is placed directly below the raised portion of the machine body 1, allowing materials to smoothly fall into the feed pipe valve 5 area due to its natural slope when transported there. This further reduces the possibility of blockage and improves the operating efficiency and stability of the equipment.

[0022] Working principle: The material to be transported is accurately introduced into the inner cavity of the machine body 1 by using the discharge pipe valve 4. Subsequently, the first motor 3 is started, which drives the spiral conveyor roller 2 to rotate in the inner cavity of the machine body 1. Through its spiral structure, the added material is smoothly transported to the area where the feed pipe valve 5 is located. Finally, the feed pipe valve 5 transfers the material to the outside, completing the entire transmission process. The second motor 9 fixedly connected to the surface of the support frame 7 is started. The rotating seat 8 provides support for the linkage block 6 while also ensuring that the linkage block 6 rotates. The second motor 9 drives the linkage block 6 to rotate while also driving the machine body 1 to deflect, causing the angle of the machine body 1 to shift and adjust its height to be consistent with the changed height. At this time, the discharge pipe valve 4 and the feed pipe valve 5 are ready and can be connected to the external feed pipe to achieve smooth material transportation. After completing the height adjustment, adjust the support leg 10 to ensure that it and the rubber shock-absorbing seat 11 together form a stable support system and remain level with the ground. Adjusting the length of the support legs 10 provides solid support for the entire device, ensuring its stability and safety. When the inner cavity of the body 1 becomes clogged, the first motor 3 can quickly activate reverse rotation mode, simultaneously driving the spiral conveyor roller 2 to rotate in the opposite direction. This ensures that accumulated materials can be transported in the reverse direction, effectively preventing material blockage in the feed pipe valve 5 area. The feed pipe valve 5 is placed directly below the raised portion of the body 1, allowing materials to fall smoothly into the feed pipe valve 5 area using the natural slope when transported there. This further reduces the probability of blockage, improves the operating efficiency and stability of the equipment, and solves the problem of replacing the screw conveyor with a screw conveyor with a different shell inclination angle when the material conveying height needs to be changed. This move undoubtedly significantly increases the overall transportation cost burden. In addition, the design limitations of traditional screw conveyors, namely the consistent direction of the spiral blades, often cause material to accumulate at the conveying end, thereby interfering with the smooth flow and normal processing of the materials.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
