Description

Technical Field

[0001] The utility model relates to a material conveying guide structure, in particular to a flexible guide structure for preventing material accumulation at a conveyor belt discharge port, and belongs to the technical field of material conveying. Background Art

[0002] In industrial production, conveyors are widely used in various material transportation equipment. However, during the use of conveyors, especially at the discharge port, material accumulation often occurs, which not only affects the normal operation of the conveyor and reduces production efficiency, but also may cause equipment failure and increase maintenance costs.

[0003] In order to solve this problem, existing technicians generally install guide plates at the discharge end of the conveyor to guide the materials. However, traditional guide plates are set at fixed angles for stability when conducting materials. Therefore, they cannot adapt well to materials of different weights or sizes and need to be manually disassembled and readjusted to meet the diversion needs.

[0004] Therefore, it is urgent to design a new structure that can effectively solve the problem of material accumulation and can adjust the angle of the diversion structure at any time to meet the diversion needs in different scenarios. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a flexible guide structure for preventing material accumulation at a conveyor belt discharge port. The flexible guide structure is based on the principle of fluid dynamics and constructs an adjustable inclination mechanism through a hinged guide plate and a tension spring. The flexible guide structure can be adaptively adjusted according to the material accumulation on the conveyor belt, effectively guiding the material flow to a predetermined discharge port to avoid material accumulation at the discharge port.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flexible guide structure for preventing material accumulation at the discharge port of a conveyor belt, comprising a conveyor belt, a guide plate arranged on one side of the discharge end of the conveyor belt, and a first support frame and a second support frame fixedly connected to the lower end of the conveyor belt; wherein the first support frame is located at the lower end of the discharge end of the conveyor belt, the guide plate is obliquely arranged below the conveyor belt, the lower end face of the guide plate is hinged on the first support frame, and the hinge point between the guide plate and the first support frame is located at a position above the center of gravity of the guide plate; the upper lower end face of the guide plate is connected to the second support frame through a tension spring.

[0007] Furthermore, the guide plate is a bent plate bucket-shaped structure, and its inclination angle in the vertical plane is 30°~45°.

[0008] Furthermore, a hinged fixing tube is welded on the lower end surface of the guide plate, and the guide plate is hinged to the first support frame through the cooperation connection between the hinged fixing tube and the pin shaft and the cotter pin.

[0009] Furthermore, the total length of the guide plate is the sum of the length of the material conveying section and the length of the material receiving section, and the center of gravity of the material receiving section is greater than the center of gravity of the material conveying section.

[0010] Furthermore, spring hanging ears are welded on the upper lower end surface of the guide plate and the second support frame, and the tension spring is connected between the guide plate and the second support frame by hanging the spring hanging ears.

[0011] The beneficial effects of the utility model are:

[0012] 1) The flexible guide structure of the utility model is based on the principle of fluid dynamics. An adjustable inclination mechanism is constructed by a hinged guide plate and a tension spring. It can be adaptively adjusted according to the accumulation of materials on the conveyor belt, effectively guiding the material flow to the predetermined discharge port to avoid material accumulation at the discharge port.

[0013] 2) The flexible guide structure of the utility model also has a certain buffering effect, which can reduce the impact of materials on the discharge port and reduce the wear and failure rate of the equipment; at the same time, it can adapt to materials of different shapes and sizes, and has strong versatility and practicality. It not only improves the operating efficiency of the conveyor and reduces maintenance costs, but also provides a new solution for material transportation in industrial production.

[0016] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example: Figure 1 As shown, the utility model provides a flexible guide structure for preventing material accumulation at a conveyor belt discharge port, comprising a conveyor belt 1, a guide plate 2 installed on one side of the discharge end of the conveyor belt 1, and a first support frame 3 and a second support frame 4 welded to the lower end of the conveyor belt 1.

[0018] The first support frame 3 is located at the lower end of the discharge end of the conveyor belt 1, the guide plate 2 is a bent plate bucket-shaped structure, the guide plate 2 is tilted and placed below the conveyor belt 1, the lower end surface of the guide plate 2 is hinged on the first support frame 3, and the hinge point between the guide plate 2 and the first support frame 3 is located above the center of gravity of the guide plate 2, so that the material dumping side of the guide plate 2 is located below the material receiving side under its own weight; the inclination angle of the guide plate 2 in the vertical plane is 30°~45°.

[0019] A hinged fixing tube is welded on the lower end surface of the guide plate 2, and the guide plate 2 is hingedly connected to the first support frame 3 through the matching connection between the hinged fixing tube and the pin shaft 5 and the cotter pin 6.

[0020] The total length of the guide plate 2 is the sum of the length of the material conveying section and the length of the material receiving section, and the center of gravity of the material receiving section is greater than the center of gravity of the material conveying section; the length of the guide plate 2 can be increased or decreased according to the material diversion throwing distance requirements, while ensuring that the hinged fixed pipe welded to the guide plate 2 is still located close to the center of gravity of the guide plate 2 and close to the material receiving side.

[0021] The upper lower end surface of the guide plate 2 is connected to the second support frame 4 through a tension spring 7. Spring hanging ears 8 are welded on the upper lower end surface of the guide plate 2 and the second support frame 4. The tension spring 7 is connected between the guide plate 2 and the second support frame 4 through the hanging spring hanging ears 8.

[0022] The specification of the tension spring 7 can be adjusted according to the actual material specific gravity and the material diversion throwing distance.

[0023] Working principle:

[0024] When there is no material accumulation on the guide plate, the guide plate is arranged at an inclination angle of 30°~45°. When the length of the guide plate is fixed, the material conveying distance is guaranteed.

[0025] When the material has strong adhesion and accumulates on the guide plate, the guide plate will slowly flip over due to the deadweight of the accumulated material under the action of the tension spring until the inclination angle is large enough. After the accumulated material slides off the guide plate, the guide plate returns to its original position under the action of the tension spring, realizing the flexible and automatic removal of accumulated material at the conveyor belt outlet.

[0026] The flexible guide structure of the utility model is based on the principle of fluid dynamics. An adjustable inclination mechanism is constructed by a hinged guide plate and a tension spring. The angle of the guide plate at the discharge port can be adaptively adjusted according to the accumulation of materials on the conveyor belt, thereby effectively guiding the material flow to the predetermined discharge port and avoiding the accumulation of materials at the discharge port.

[0027] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
