Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and in particular to a stone conveyor belt with uniform material distribution function. Background Technology

[0002] Zircon sand, also known as zircon ore, is an important mineral resource. Due to its unique physical and chemical properties, it is widely used in many industries, mainly in the manufacture of ceramics, glass, enamel, and metallic zircon. Zircon sand plays an indispensable role in modern industry. In the ceramics industry, it is used as a high-quality raw material to make the finished product stronger and more wear-resistant. In glass manufacturing, it helps to improve the transparency and strength of the product. In addition, zircon sand also has important applications in the production of coatings and refractory materials. During the mining of zircon sand, a large amount of stone is generated. Usually, the larger stones are crushed, and the smaller stones are crushed again. After processing, the stone needs to be stored and then transported to the dock for loading.

[0003] When conveying stones, the high density of the stones increases the burden on the conveyor belt. To avoid uneven distribution of stones causing fluctuations in the load on the conveyor belt and affecting its service life, a feeding structure is usually set up to replenish the stones. For example, Chinese Patent Publication No. CN211970848U discloses "a uniform feeding device with spraying function for stone conveyors". The feeding roller can be used to uniformly distribute the stones and can also be used as a spray pipe suspended above the conveyor belt to spray and wet the stones, solving the problem of dust flying during feeding. The feeding roller is rotated by a motor and translated by a translation component. The stones are spread out through the rotation and translation action, resulting in a better feeding effect.

[0004] However, in actual use, many stones are inherently hard, resulting in a large volume even after crushing. When the conveyor belt is transporting large stones, the load increases, and the material distribution rollers hinder the movement of large stones during distribution, causing large stones to clog the conveyor belt and affecting its normal operation. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the material distribution rollers hindering the movement of large-volume stones during material distribution, causing large-volume stones to clog the conveyor belt and affecting the normal operation of the conveyor belt. Therefore, this invention proposes a stone conveyor belt with uniform material distribution function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a stone conveyor belt with uniform material distribution function, including a conveyor belt body, a support frame on the outside of the conveyor belt body, a material distribution roller on the support frame, a screening mechanism on the support frame, a trigger component that cooperates with the screening mechanism on the support frame, a discharge port that cooperates with the screening mechanism on the support frame, and a discharge plate fixedly installed on the discharge port.

[0008] The screening mechanism includes a power structure and a pusher plate. The support frame has a groove that cooperates with the pusher plate. A guide rail is fixedly installed on the support frame. A connecting frame is fixedly installed on the pusher plate. A guide wheel that is rotatably connected to the guide rail is installed on the connecting frame.

[0009] Furthermore, the triggering component includes a fixing plate, a trigger plate is provided on one side of the fixing plate, and a switch that cooperates with the power structure is provided on the fixing plate.

[0010] Furthermore, a first guide rod is fixedly mounted on the trigger plate, the first guide rod is movably inserted into the fixed plate, a reset spring is provided between the fixed plate and the trigger plate, and a trigger rod penetrating the fixed plate is provided on one side of the switch.

[0011] Furthermore, the power structure includes a power arm, and a mounting frame is fixedly mounted on the support frame, with the power arm rotatably connected to the mounting frame.

[0012] Furthermore, a sliding groove is provided on the power arm, and a second guide rod that is slidably connected to the sliding groove is fixedly provided on the connecting frame.

[0013] Furthermore, a hydraulic rod is rotatably mounted on the support frame, and a connecting frame is fixedly mounted on the output shaft of the hydraulic rod, the connecting frame being rotatably connected to the power arm.

[0014] The stone conveyor belt with uniform material distribution function proposed in this utility model has the following advantages:

[0015] In this utility model, by setting a trigger component and a screening mechanism, when there are large stones on the conveyor belt, the stones move with the conveyor belt and come into contact with the trigger plate, pushing the trigger plate to move and contact the trigger rod to activate the switch, thereby opening the screening mechanism. The stones in front of the trigger plate are pushed out of the discharge port and the unloading plate by the pusher plate to be screened out, so as to avoid the stones blocking the conveyor belt and affecting normal use.

[0016] Secondly, in this utility model, by setting a guide rail and a guide wheel to cooperate, the movement trajectory of the connecting frame and the pusher plate is restricted, so as to prevent the pusher plate from deviating from the preset movement trajectory and failing to push the stone after contacting a large volume stone due to excessive force on itself.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A stone conveyor belt with uniform material distribution function includes a conveyor belt body 1, a support frame 2 is provided on the outside of the conveyor belt body 1, a material distribution roller 3 is provided on the support frame 2, a screening mechanism 4 is also provided on the support frame 2, a trigger component 5 that cooperates with the screening mechanism 4 is provided on the support frame 2, a discharge port that cooperates with the screening mechanism 4 is provided on the support frame 2, and a discharge plate 6 is fixedly provided on the discharge port.

[0024] The screening mechanism 4 includes a power structure 41 and a pusher plate 42. The support frame 2 has a groove that matches the pusher plate 42. A guide rail is fixedly installed on the support frame 2. A connecting frame 43 is fixedly installed on the pusher plate 42. A guide wheel 44 that is rotatably connected to the guide rail is installed on the connecting frame 43.

[0025] In this utility model, the trigger component 5 cooperates with the screening mechanism 4. When there are large-volume stones on the conveyor belt body 1, the stones move with the conveyor belt and come into contact with the trigger component 5, thereby opening the screening mechanism 4. The pusher plate 42 pushes the stones in front of the trigger component 5 out through the discharge port and the unloading plate 6 to remove them, so as to avoid the stones blocking the conveyor belt and affecting normal use. The material is then evenly distributed by the distribution roller 3.

[0026] Furthermore, in this embodiment, the triggering component 5 includes a fixed plate 51, a triggering plate 52 is provided on one side of the fixed plate 51, and a switch 53 that cooperates with the power structure 41 is provided on the fixed plate 51. Large-volume stones move with the conveyor belt and come into contact with the triggering plate 52, pushing the triggering plate 52 to move and contact the switch 53 to activate the switch 53, thereby opening the screening mechanism 4.

[0027] Furthermore, in this embodiment, a first guide rod 54 is fixedly installed on the trigger plate 52. The first guide rod 54 is movably connected to the fixed plate 51. A reset spring is provided between the fixed plate 51 and the trigger plate 52. A trigger rod 55 is provided on one side of the switch 53, penetrating the fixed plate 51. As the volume of stone moves with the conveyor belt, it pushes the trigger plate 52 to move and contact the trigger rod 55 to activate the switch 53, thereby opening the screening mechanism 4. The stone in front of the trigger plate 52 is pushed out and screened along the discharge port and the unloading plate 6 by the pusher plate 42, so as to avoid the stone clogging the conveyor belt and affecting normal use.

[0028] It should be noted that in this embodiment, the power structure 41 includes a power arm 411, and a mounting frame 412 is fixedly installed on the support frame 2. The power arm 411 and the mounting frame 412 are rotatably connected by a rotating shaft. When the power arm 411 swings around the rotating shaft, the pusher plate 42 moves accordingly to push or reset.

[0029] Furthermore, in this embodiment, a sliding groove 413 is provided on the power arm 411, and a second guide rod 414 is fixedly provided on the connecting frame 43 and slidably connected to the sliding groove 413. When the power arm 411 swings, the position of the sliding groove 413 changes, driving the second guide rod 414 and the connecting frame 43 to move, thereby driving the pusher plate 42 to move and push the large volume stone.

[0030] More specifically, in this embodiment, a hydraulic rod 415 is rotatably mounted on the support frame 2, and a connecting frame 416 is fixedly mounted on the output shaft of the hydraulic rod 415. The connecting frame 416 is rotatably connected to the power arm 411. The power arm 411 is driven to rotate by the hydraulic rod 415, and the angle of the hydraulic rod 415 changes accordingly with the change of the angle of the power arm 411.

[0031] Working method: During operation, large-volume stones move with the conveyor belt and come into contact with the trigger plate 52, pushing the trigger plate 52 to move and contact the trigger rod 55 to activate the switch 53, thereby opening the screening mechanism 4. The hydraulic rod 415 drives the power arm 411 to rotate. The power arm 411 swings around the rotating shaft on the mounting frame 412, changing the position of the chute 413, driving the second guide rod 414 and the connecting frame 43 to move, which in turn drives the pusher plate 42 to move and push the large-volume stones. The stones in front of the trigger plate 52 are pushed out of the screen along the discharge port and the unloading plate 6 to avoid the stones clogging the conveyor belt and affecting normal use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
