Description

Technical Field

[0001] This utility model relates to the field of coal processing technology, specifically a spill-proof guide trough with coal recovery function. Background Technology

[0002] During the production and transportation of coal, it is necessary to collect samples to determine the quality of the coal. When collecting coal samples, a primary sampler is needed to collect them from the conveyor belt carrying the coal.

[0003] Chinese patent publication number "CN 217126061 U" discloses "an external anti-spillage device for a material guide trough", which includes a material guide trough body, multiple material guide trough support frames, an anti-spillage mechanism, and a conveying mechanism. The multiple material guide trough support frames are spaced apart on both sides of the material guide trough body. The material guide trough body is installed above the conveying mechanism. The anti-spillage mechanism is installed on the material guide trough support frame between each material guide trough support frame and the conveying mechanism. This invention has the technical characteristics of effectively reducing the wear of rubber protective sheets and preventing large amounts of material from spilling or leaking out from the gaps in the rubber protective sheets, thereby reducing the labor intensity of cleaning personnel, improving the comfort of the working environment, and reducing the health threat of environmental pollution to workers. It has good application prospects. However, when the sampling device is used, because the sampling head of the primary sampler is perpendicular to the direction of belt operation, some coal is quickly pushed to one side of the belt during sampling, which easily causes coal to spill onto the ground near the sampling head, resulting in poor cleanliness of the production site and a large workload for cleaning workers. Therefore, we have proposed a spill-proof guide trough with coal recovery function. Utility Model Content

[0004] The purpose of this utility model is to provide a spill-proof guide trough with coal recovery function to solve the problem in the existing sampling equipment where, during sampling, the sampling head of the primary sampler is perpendicular to the belt running direction, causing some coal to be quickly pushed to one side of the belt during sampling, which easily leads to coal spillage on the ground near the sampling head, resulting in poor cleanliness of the production site and a large workload for cleaning workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spill-proof guide trough with coal recycling function, including a mounting frame, a shielding frame fixed at the bottom of the mounting frame, a spill-proof collection mechanism on one side of the shielding frame, and an installation mechanism on the outside of the spill-proof collection mechanism. The installation mechanism facilitates the disassembly of the recycling box, making it convenient to remove and utilize the collected coal as a whole, thus improving the convenience of the device.

[0006] The anti-fall collection mechanism includes a guide frame fixed to the bottom edge of the shielding frame, a return pipe fixed to the bottom of the guide frame, a recycling box connected to the bottom of the return pipe through the installation mechanism, and an installation shell fixed through the top of the guide frame, with a stop block sliding inside the installation shell.

[0007] Preferably, the anti-fall collection mechanism further includes fixed seats symmetrically fixed to the top of the abutment block, with a connecting rod rotating inside the fixed seat, a sliding rod fixed to the top between the left and right sides of the inner cavity of the mounting shell, movable seats symmetrically sliding on the outer side of the sliding rod, a first spring fixed between the two movable seats, limit grooves opened at the bottom of both sides of the inner side of the mounting shell, and limit blocks fixed to the top of both sides of the abutment block.

[0008] Preferably, the connecting rod rotates inside the movable seat, which facilitates the movement of the movable seat when the connecting rod deflects, and the first spring is sleeved on the outside of the slide rod.

[0009] Preferably, the outer wall of the abutment block is fitted with the inner wall of the mounting shell to ensure stable movement of the abutment block, and the guide frame is located on one side of the sampling head rotation direction.

[0010] Preferably, the limiting block slides inside the limiting groove, and the outer wall of the limiting block is in contact with the inner wall of the limiting groove to limit the block and prevent it from falling off.

[0011] Preferably, the installation mechanism includes a fixing plate fixed to both sides of the fall pipe, a connecting rod symmetrically sliding through the top of the fixing plate, a pressing plate fixed to the top of the connecting rod, a second spring sleeved on the outer top of the connecting rod, a connecting plate fixed to the bottom of the connecting rod, an insertion rod fixed to the top of the connecting plate, ear plates fixed to the top of both sides of the recycling box, and an insertion hole through the middle of the top of the ear plate.

[0012] Preferably, the upper and lower ends of the second spring are fixedly connected to the bottom of the pressing plate and the top of the fixing plate, respectively, so as to facilitate the pressing plate to reset and the connecting rod to drive the connecting plate to reset.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes the anti-fall collection mechanism. The potential energy stored in the first spring enables the first spring to contract, thereby bringing the moving seats closer together and causing the connecting rod to deflect. This causes the fixed seat to move the abutment block, making the abutment block fit against the surface of the conveyor belt. When the sampling head rotates to sample, the abutment block is used to block and reduce the amount of coal spillage. A small portion of the coal is squeezed from the bottom of the abutment block and discharged into the guide frame when the conveyor belt deforms, falling into the recycling box through the return pipe. This effectively prevents coal from spilling onto the ground, ensuring environmental cleanliness and facilitating the recycling of coal that falls from the conveyor belt, thus improving the practicality of the device.

[0015] 2. In this application, by using the installation mechanism, pressing the pressing plate causes the connecting rod to descend, compressing the second spring and simultaneously causing the connecting plate to descend, thus removing the insertion rod from the insertion hole, releasing the ear plate from fixation, facilitating the disassembly of the recycling box, and making it convenient to remove and utilize the collected coal as a whole, thereby improving the convenience of the device.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5 As shown, this utility model provides a technical solution for an anti-spillage guide trough with coal recycling function, including a mounting frame 100, a shielding frame 200 fixed at the bottom of the mounting frame 100, an anti-spillage collection mechanism 300 provided on one side of the shielding frame 200, and an installation mechanism 400 provided on the outside of the anti-spillage collection mechanism 300.

[0024] Please see Figure 2 and Figure 3 The anti-fall collection mechanism 300 includes a guide frame 310 fixed to the bottom edge of the shield frame 200, a return pipe 320 fixed to the bottom of the guide frame 310, a recycling box 330 connected to the bottom of the return pipe 320 via an installation mechanism 400, and an installation shell 340 fixed through the top of the guide frame 310. A stop block 350 slides inside the installation shell 340. The anti-fall collection mechanism 300 also includes fixing seats 360 symmetrically fixed to the top of the stop blocks 350. The fixing seats 360 have internal... A connecting rod 370 rotates within the inner cavity of the mounting housing 340. A sliding rod 380 is fixed to the top between the left and right sides of the inner cavity. A movable seat 381 slides symmetrically on the outer side of the sliding rod 380. A first spring 382 is fixed between the two movable seats 381. Limiting grooves 390 are formed at the bottom of both sides of the inner cavity of the mounting housing 340. Limiting blocks 391 are fixed to the top of both sides of the abutment 350. The connecting rod 370 rotates within the movable seat 381, and the first spring 382 is sleeved on the outer side of the sliding rod 380. The abutment 350... The outer wall of the sampler 310 is in contact with the inner wall of the mounting housing 340, and the guide frame 310 is located on one side of the rotation direction of the sampling head; the limiting block 391 slides inside the limiting groove 390, and the outer wall of the limiting block 391 is in contact with the inner wall of the limiting groove 390; by utilizing the anti-fall collection mechanism 300, the potential energy of the first spring storage 382 is used to make the first spring 382 have the ability to contract, thereby causing the moving seats 381 to move closer to each other, causing the connecting rod 370 to deflect, thereby causing the fixed seat 36 to move closer to each other. The sampling head moves the abutment block 350, making it fit against the surface of the conveyor belt. When the sampling head rotates to sample, the abutment block 350 is used to block the flow, reducing the amount of coal spilled. A small portion of the coal is squeezed from the bottom of the abutment block 350 and discharged into the guide frame 310 when the conveyor belt deforms. It then falls into the recycling box 330 through the return pipe 320, thus effectively preventing coal from spilling onto the ground, ensuring environmental cleanliness, and facilitating the recycling of coal that falls from the conveyor belt, thereby improving the practicality of the device.

[0025] Please see Figure 4 and Figure 5 The installation mechanism 400 includes fixing plates 410 fixed to both sides of the fall pipe 320. A connecting rod 420 is symmetrically slidably traversed through the top of the fixing plate 410. A pressing plate 430 is fixed to the top of the connecting rod 420. A second spring 440 is sleeved on the outer top of the connecting rod 420. A connecting plate 450 is fixed to the bottom of the connecting rod 420. An insertion rod 460 is fixed to the top of the connecting plate 450. Ear plates 470 are fixed to the tops of both sides of the recycling box 330. An insertion hole 4 is formed through the center of the top of the ear plate 470. 80; The upper and lower ends of the second spring 440 are fixedly connected to the bottom of the pressing plate 430 and the top of the fixing plate 410, respectively; By using the installation mechanism 400, pressing the pressing plate 430 causes the connecting rod 420 to descend, compressing the second spring 440 and simultaneously causing the connecting plate 450 to descend, so that the insertion rod 460 moves out of the insertion hole 480, releasing the fixing of the ear plate 470, making it easier to disassemble the recycling box 330, and making it easier to take out the collected coal as a whole for use, thus improving the convenience of the device.

[0026] In use, this invention works as follows: when the sampling head rotates to take a sample, it pushes the coal to one side of the conveyor belt. The potential energy stored in the first spring 382 allows the spring to contract, causing the moving seats 381 to move closer together. This causes the connecting rod 370 to deflect, which in turn causes the fixed seat 360 to move the abutment block 350, bringing it into contact with the surface of the conveyor belt. When the sampling head rotates to take a sample, the abutment block 350 acts as a shield, reducing the amount of coal spilled. A small portion of the coal, when the conveyor belt deforms, is squeezed from the bottom of the abutment block 350 and discharged into the guide frame 310, falling into the recovery box 330 through the return pipe 320. When it is necessary to retrieve the coal from inside the recovery box 330, the pressing plate 430 is pressed, and the conveyor belt... The moving connecting rod 420 descends, compressing the second spring 440 and simultaneously causing the connecting plate 450 to descend, thus moving the insertion rod 460 out of the insertion hole 480. This releases the fixing of the ear plate 470, facilitating the disassembly of the recycling box 330 and the emptying of the internal coal. Then, the pressing plate 430 is pressed again to align the top of the recycling box 330 with the bottom of the return tube 320. The pressing plate 430 is then loosened, and the second spring 440 resets, causing the pressing plate 430 to move the connecting rod 420 back to its original position. This, in turn, causes the connecting plate 450 to move the insertion rod 460 back to its original position, allowing the insertion rod 460 to be embedded in the insertion hole 480. At the same time, the connecting plate 450 presses the ear plate 470 upwards, bringing the recycling box 330 into contact with the return tube 320 for easier subsequent collection.
