Description

Technical Field

[0001] This utility model relates to the field of ore conveying technology, and in particular to an anti-overflow guide trough for ore conveyor belts. Background Technology

[0002] Ores are aggregates of minerals with economic value found in the Earth's crust. They can be classified according to their uses into metallic ores (such as iron, copper, and aluminum ores) and non-metallic ores (such as coal and limestone). In industrial production, the physical properties of ores (hardness, density, moisture content) directly influence the choice of transportation methods.

[0003] In existing technologies, during the ore conveying process, ore needs to be transported onto the conveyor belt via a guide chute. However, the inclination angle of the guide chute currently installed above the conveyor belt is relatively fixed. When different sizes of ore slide down through the guide chute, the contact area between the ore and the guide chute is different, resulting in different frictional forces. This causes different sizes of ore to slide from the guide chute onto the conveyor belt at different speeds, which may lead to ore accumulation at the drop point on the conveyor belt. Consequently, the ore may roll off the conveyor belt, causing spillage. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where, during the ore conveying process, ore needs to be transported onto the conveyor belt via a guide chute. However, the current guide chute installed above the conveyor belt has a relatively fixed inclination angle. When different sizes of ore slide down through the guide chute, the contact area between the ore and the guide chute is different, resulting in different frictional forces. This causes different sizes of ore to slide down from the guide chute onto the conveyor belt at different speeds, which may lead to ore accumulation at the drop point on the conveyor belt. Consequently, the ore may roll off the conveyor belt, causing overflow.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-overflow guide trough for ore conveyor belts, comprising: a bottom plate, and further comprising:

[0006] Two H-shaped support frames are symmetrically fixedly connected to the top of the base plate. One of the H-shaped support frames has a round rod 1 fixedly connected to the opposite side near the top. The outer surface of the round rod 1 is rotatably connected to the main body of the material guide trough. The other H-shaped support frame has arc-shaped grooves on the opposite side near the top. The opposite side of the main body of the material guide trough is fixedly connected to a sliding rod. The outer surface of the sliding rod is slidably connected to the inside of the arc-shaped groove. A connecting plate is fixedly connected to the opposite side of the two H-shaped support frames. A U-shaped block 1 is fixedly connected to the top of the connecting plate. A round rod 2 is fixedly connected to the opposite side of the two arms of the U-shaped block 1. A hydraulic telescopic rod is rotatably connected to the outer surface of the round rod 2. A U-shaped block 2 is fixedly connected to the bottom of the main body of the material guide trough. A round rod 3 is fixedly connected to the opposite side of the two arms of the U-shaped block 2. The round rod 3 is rotatably connected to the hydraulic telescopic rod.

[0007] Preferably, a fixed rod is fixedly connected to each opposite side of the main body of the feed trough, and a movable block is rotatably connected to the outer surface of the fixed rod. A buffer frame is fixedly connected to one side of each of the two movable blocks.

[0008] Preferably, each of the opposite sides of the buffer frame near the bottom is rotatably connected to a movable rod, and one end of the movable rod is fixedly connected to a tension spring.

[0009] Preferably, each of the opposite sides of the main body of the guide trough near the top is rotatably connected to a movable rod two, and the movable rod two is fixedly connected to a tension spring.

[0010] Preferably, the top of the material guide trough body is symmetrically and fixedly connected with two anti-overflow skirts, which are inclined outwards.

[0011] Preferably, the height of one of the H-shaped support frames is greater than the height of the other H-shaped support frame, and the connecting plate is inclined.

[0012] Preferably, the main body of the feed trough is inclined, and the anti-overflow skirt is inclined.

[0013] Preferably, a conveyor belt body is provided below the buffer frame.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to activate the hydraulic telescopic rod, causing it to retract. This retraction applies a pulling force to the three round rods and the two U-shaped blocks, causing the main body of the guide chute to rotate downwards at an appropriate angle around the outer surface of the first round rod. Simultaneously, the sliding rod slides downwards at an appropriate distance along the inside of the arc-shaped groove, and the two ends of the hydraulic telescopic rod rotate at appropriate angles around the second and third round rods, respectively. This allows for appropriate adjustment of the inclination angle of the guide chute main body according to the size of the ore being conveyed, preventing larger ore from sliding down slowly and smaller ore from sliding down quickly. This controls the sliding speed of different sized ore, avoiding ore accumulation at the material drop point of the conveyor belt and preventing ore from rolling off the conveyor belt and causing spillage.

[0016] 2. In this utility model, when the ore on the main body of the feed chute slides onto the buffer frame, the buffer frame will be subjected to pressure, causing the movable block to rotate downward at an appropriate angle along the outer surface of the fixed rod. Simultaneously, the movable rod's first pair of tension springs will apply a downward pulling force, causing the tension springs to stretch. Simultaneously, the second movable rod and the first movable rod will rotate at an appropriate angle, and under the restoring force of the tension springs, an upward pulling force will be applied to the buffer frame. This can buffer the ore falling onto the conveyor belt body to a certain extent, reducing the impact force of the ore on the conveyor belt body, thereby reducing the wear of the conveyor belt body, avoiding damage to the conveyor belt body, and thus improving the service life of the conveyor belt body.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1-4 As shown, this utility model provides an anti-overflow material guide trough for ore conveyors, including: a base plate 1, and two H-shaped support frames 101, symmetrically fixedly connected to the top of the base plate 1. One H-shaped support frame 101 has a round rod 102 fixedly connected to its opposite side near the top, and the outer surface of the round rod 102 is rotatably connected to the guide trough body 103. The other H-shaped support frame 101 has arc-shaped grooves 106 on its opposite side near the top, and sliding rods 107 are fixedly connected to the opposite side of the guide trough body 103. The outer surface of the sliding rods 107 slides... Inside the arc-shaped groove 106, a connecting plate 105 is fixedly connected to one side of the two H-shaped support frames 101. A U-shaped block 108 is fixedly connected to the top of the connecting plate 105. A round rod 111 is fixedly connected to one side of the two arms of the U-shaped block 108. A hydraulic telescopic rod 109 is rotatably connected to the outer surface of the round rod 111. A U-shaped block 110 is fixedly connected to the bottom of the guide trough body 103. A round rod 112 is fixedly connected to one side of the two arms of the U-shaped block 110. The round rod 112 is rotatably connected to the hydraulic telescopic rod 109.

[0026] Furthermore, such as Figure 1-4 As shown, fixed rods 205 are fixedly connected to opposite sides of the feed chute body 103. Movable blocks 204 are rotatably connected to the outer surface of the fixed rods 205. Buffer frames 2 are fixedly connected to one side of each of the two movable blocks 204. Through the above arrangement, the movable blocks 204 and buffer frames 2 can rotate around the outer surface of the fixed rods 205 at an appropriate angle.

[0027] Furthermore, such as Figure 1-4 As shown, the opposite sides of the buffer frame 2 near the bottom are rotatably connected to movable rods 201. One end of the movable rod 201 is fixedly connected to a tension spring 202. With the above arrangement, when the ore falls on the buffer frame 2, the tension spring 202 will be subjected to a tension force, causing the movable rod 201 to rotate at an appropriate angle.

[0028] Furthermore, such as Figure 1-4 As shown, movable rods 203 are rotatably connected to opposite sides of the main body 103 near the top. Movable rods 203 are fixedly connected to tension springs 202. With the above arrangement, when tension springs 202 are subjected to tension, movable rods 203 will rotate at an appropriate angle.

[0029] Furthermore, such as Figure 1-4 As shown, two anti-overflow skirts 104 are symmetrically fixedly connected to the top of the feed chute body 103. The anti-overflow skirts 104 are inclined outwards. By setting the anti-overflow skirts 104, the overflow of ore can be prevented.

[0030] Furthermore, such as Figure 1-4 As shown, the height of one H-shaped support frame 101 is greater than the height of the other H-shaped support frame 101. The connecting plate 105 is inclined. The connection plate 105 facilitates the connection and fixation of the two H-shaped support frames 101, thereby improving the stability of the two H-shaped support frames 101.

[0031] Furthermore, such as Figure 1-4 As shown, the main body 103 of the feed chute is inclined, which facilitates the downward sliding of the ore along the main body 103 of the feed chute.

[0032] Furthermore, such as Figure 1-4 As shown, a conveyor belt body 3 is provided below the buffer frame 2, which facilitates the transportation of ore.

[0033] Working Principle: During operation, ore is poured into the guide chute body 103, allowing it to slide downwards along the chute body 103 and onto the conveyor belt body 3. The anti-overflow skirt 104 prevents ore spillage. The controller activates the hydraulic telescopic rod 109, causing it to retract and apply tension to the round rod 112 and U-shaped block 110. This causes the guide chute body 103 to rotate downwards around the outer surface of the round rod 102 at an appropriate angle. Simultaneously, the sliding rod 107 slides downwards along the inside of the arc-shaped groove 106 a suitable distance, and both ends of the hydraulic telescopic rod 109 rotate around the round rod 111 and round rod 112 at appropriate angles. This allows for appropriate adjustment of the tilt angle of the guide chute body 103 according to the size of the ore being conveyed, preventing larger ore from sliding slowly and smaller ore from sliding quickly. This ensures the smooth flow of ore of different sizes. Speed ​​control prevents ore accumulation at the material drop point of the conveyor belt body 3, thus preventing ore from rolling off the conveyor belt body 3 and causing spillage. When ore slides from the guide chute body 103 onto the buffer frame 2, the buffer frame 2 is subjected to pressure, causing the movable block 204 to rotate downwards at an appropriate angle along the outer surface of the fixed rod 205. Simultaneously, the movable rod 1 201 applies a downward pulling force to the tension spring 202, causing the tension spring 202 to stretch. Simultaneously, the movable rod 203 and the movable rod 1 201 rotate at an appropriate angle, and under the reset force of the tension spring 202, an upward pulling force is applied to the buffer frame 2. This can buffer the ore falling onto the conveyor belt body 3 to a certain extent, reducing the impact force of the ore on the conveyor belt body 3, thereby reducing the wear of the conveyor belt body 3, preventing damage to the conveyor belt body 3, and thus improving the service life of the conveyor belt body 3.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
