Description

Technical Field

[0001] The utility model relates to a conveyor belt transfer funnel buffer fork, which can reduce the impact of materials on the lower conveyor belt and extend the service life of the conveyor belt, and belongs to the technical field of conveying. Background Art

[0002] A single conveyor belt can only transport materials in a straight line. When the material's direction needs to be changed, multiple conveyors are usually required to transport the material to the desired location. Transfer hoppers are used to transfer material between adjacent conveyors. Because the material has a large drop when passing through the transfer hopper, it has a significant impact on the lower conveyor belt, which can easily damage the conveyor belt and shorten its service life. Therefore, it is essential to design a transfer hopper buffer device that can reduce material impact. Utility Model Content

[0003] The purpose of the utility model is to provide a conveyor belt transfer funnel buffer fork to address the shortcomings of the existing technology, so as to reduce the impact of materials on the lower conveyor belt and extend the service life of the conveyor belt.

[0005] A conveyor belt transfer funnel buffer fork includes a fixed beam and multiple steel teeth. The multiple steel teeth are installed inside the conveyor belt transfer funnel and are arranged along the width direction of the lower conveyor belt. Each steel tooth is a parabolic curve structure with the front end lower than the rear end. The rear end of the steel tooth is fixedly connected to the fixed beam, and the rear ends of adjacent steel teeth are connected to each other by steel plates. The fixed beam is fixedly connected to the two side walls of the transfer funnel.

[0006] The above-mentioned conveyor belt transfer funnel buffer fork also includes two torque arms, which are parallel to the material conveying direction of the lower conveyor belt and symmetrically arranged on both sides of the transfer funnel. The front end of each torque arm is connected to the frame of the lower conveyor belt through a support, and the two ends of the fixed beam are respectively fixedly connected to the rear ends of the two torque arms.

[0007] The above-mentioned conveyor belt transfer funnel buffer fork has wear-resistant blocks installed on the upper surfaces of the steel teeth, and the wear-resistant blocks are connected to the steel teeth by bolts.

[0008] The above-mentioned conveyor belt transfer funnel buffer fork is connected by flanges between the fixed beam and the two side walls of the transfer funnel, and between the fixed beam and the two torque arms.

[0009] The utility model utilizes multiple steel teeth to receive the material flow falling from above and changes the direction of the material flow so that the material generates a speed consistent with the running direction of the lower conveyor belt before falling into the lower conveyor belt, thereby greatly reducing the impact of the material on the lower conveyor belt and extending the service life of the conveyor belt.

[0015] The utility model aims to solve the problems in the prior art and provides a conveyor belt transfer funnel buffer fork, which can reduce the impact of materials on the lower conveyor belt when passing through the transfer funnel, thereby protecting the lower conveyor belt.

[0016] See Figure 1-Figure 3 The utility model mainly includes a wear-resistant block 1, a torque arm 2, a fixed beam 3, an inner flange 4, an outer flange 5 and steel teeth 6.

[0017] As shown in the figure, the buffer fork is a structure with a low front and a high rear (the material conveying direction of the lower conveyor belt is the front), and multiple steel teeth 6 are installed inside the conveyor belt transfer funnel (the transfer funnel is not drawn in the figure) and are arranged along the width direction of the lower conveyor belt. The steel teeth 6 are a parabolic curve structure. The front end of each steel tooth 6 is lower than the rear end. The rear ends of multiple steel teeth 6 are welded to the fixed beam 3. The rear ends of adjacent steel teeth 6 are connected to each other through steel plates, so that all steel teeth 6 become a whole to strengthen the overall structure and ensure its stability. A replaceable wear-resistant block 1 is installed on the upper surface of each steel tooth 6. The wear-resistant block 1 is connected to the steel tooth 6 with bolts. The two ends of the fixed beam 3 pass through the transfer The two side walls of the connecting funnel and each end of the fixed beam 3 are provided with two flanges, namely the inner flange 4 and the outer flange 5. The fixed beam 3 is fixedly connected to the side wall of the transfer funnel through the inner flange 4. The two torque arms 2 are parallel to the material conveying direction of the lower conveyor belt and are symmetrically arranged on both sides of the transfer funnel. The two ends of the fixed beam 3 are fixedly connected to the two torque arms 2 through the outer flange 5. The inner flange 4 and the side wall of the transfer funnel, and the outer flange 5 and the torque arm 2 are all connected by bolts. The torque arm 2 is fixedly connected to the frame of the lower conveyor belt through the support. The torque generated by the torque arm 2 can overcome the torque generated by the impact and deadweight of the steel teeth 6 on the fixed beam 3.

[0018] The wear-resistant block 1 is a wear-resistant material with a "T"-shaped cross-section and is approximately rectangular. The torque arm 2 is a channel steel with a flange at one end arranged on both sides of the transfer funnel. The rear end of the torque arm 2 with the flange is connected to the outer flange 5, and the front end of the torque arm 2 is placed on the support to prevent the buffer fork from flipping over under the impact of the material.

[0019] The steel teeth 6 are connected to the wear-resistant block 1 by bolts, and the wear-resistant block 1 can be replaced at any time according to the degree of wear.

[0020] The usage process of the utility model is as follows: the steel teeth 6 and the fixed beam 3 are welded into a whole, the fixed beam 3 and the transfer funnel are fixed with bolts through the inner flange 4, and the torque arm 2 is connected to the outer flange 5 on the fixed beam 3, providing the fixed beam 3 with a torque opposite to the steel teeth 6. When the material falls on the steel teeth 6, the speed will be reduced and the direction of movement will be changed, reducing the impact of the material on the lower conveyor belt.

[0021] An embodiment of the present invention is as follows:

[0022] Wear-resistant block 1 is 240 mm long and 60 mm high;

[0023] The length of the torque arm 2 is 1280 mm and the width is 200 mm;

[0024] The fixed beam 3 has a length of 1856 mm and a diameter of 196 mm;

[0025] The diameter of the inner flange 4 and the outer flange 5 is 440 mm;

[0026] The width of the steel teeth 6 is 80 mm and the length is 2171 mm.

[0027] This new design, installed inside the transfer hopper, utilizes steel teeth with a curving design to receive the material flowing downward and redirect it, allowing the material to travel at a speed consistent with the conveyor belt's direction before hitting the lower conveyor belt. This reduces the impact of the material on the lower conveyor belt, thereby extending the conveyor belt's service life. Torque arms are installed at both ends of the fixed beam to ensure the buffer fork remains stable and prevents it from flipping under material impact. Wear-resistant blocks can be replaced at any time based on wear, significantly extending the buffer fork's service life.
