Description

Technical Field

[0001] This utility model relates to the field of sand and gravel aggregate conveying technology, and more specifically, to a long belt conveyor for conveying sand and gravel aggregate. Background Technology

[0002] Sand and gravel aggregates play a number of key roles in building materials. In concrete and asphalt, they act as a skeleton structure, significantly enhancing the strength and stability of the materials, improving load-bearing capacity and durability. By selecting sand and gravel of different particle sizes, voids in concrete and asphalt can be filled, increasing the density of the materials. This not only reduces drying shrinkage and cracking, but also improves the overall stability of the materials.

[0003] However, existing sand and gravel aggregate conveying devices still have many shortcomings in actual use. For example, when conveying sand and gravel aggregates on a long conveyor belt, the bumps will cause the sand and gravel aggregates to be pushed into the conveyor belt, which cannot push and center the sand and gravel aggregates. On the one hand, the sand and gravel aggregates will continuously rub and accumulate on the inside of the conveyor belt, which will easily aggravate the wear of the belt and related components, shorten the service life of the equipment, and increase the maintenance and replacement costs. On the other hand, it will cause blockages in some parts of the conveyor belt, affecting the normal conveying process, and may even lead to the shutdown and failure of the conveying system. Utility Model Content

[0004] The present invention provides a long belt conveyor for conveying sand and gravel aggregates, which aims to solve the problem that existing devices cannot push and center sand and gravel aggregates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a long belt conveyor for conveying sand and gravel aggregates, comprising a support platform, a conveyor belt, and two push plates. The conveyor belt is disposed inside the support platform, and the two push plates are disposed on the top of the conveyor belt. Two connecting rods are fixedly connected to the opposite sides of the two push plates. The ends of the connecting rods away from the push plates pass through both sides of the support platform. A pressure plate is fixedly connected between the ends of the two connecting rods away from the push plates. A first spring is sleeved on the outside of the connecting rods and between the opposite side of the two push plates and the inner wall of the support platform. An eccentric disc is rotatably connected to both sides of the bottom of the support platform. The outer side of the eccentric disc contacts one side of the corresponding pressure plate. A worm gear is fixedly connected to the central shaft of the eccentric disc. Two fixed plates are rotatably connected to the bottom of the support platform. A worm is rotatably connected between the interior of the two fixed plates. The worm gear meshes with the worm.

[0006] In a preferred embodiment, the worm gear is externally fixedly connected to two first bevel gears, the bottom of the support platform is fixedly connected to a first motor, the output shaft of the first motor is fixedly connected to a second bevel gear, and the first bevel gears are meshed with the second bevel gears.

[0007] In a preferred embodiment, limit rods are fixedly connected to both sides of the support platform, and limit blocks are fixedly connected to the ends of the limit rods away from the support platform. The pressure plates are slidably connected to the corresponding limit rods, and a second spring is sleeved on the outside of the limit rods and between the side of the two pressure plates that is far apart and the side of the limit block.

[0008] In a preferred embodiment, a U-shaped frame is fixedly connected to the top of the support platform, and a dust collection box is fixedly connected to the bottom of the U-shaped frame and above the conveyor belt. A filter plate is fixedly connected to the bottom of the dust collection box.

[0009] In a preferred embodiment, a vacuum pump is fixedly connected to the top of the U-shaped frame, and a connecting pipe is fixedly connected to the output end of the vacuum pump. The end of the connecting pipe away from the vacuum pump extends into the interior of the vacuum box, and a dust discharge pipe is fixedly connected to the output end of the vacuum pump.

[0010] In a preferred embodiment, a second motor is fixedly connected to one side of the support platform, and the output shaft of the second motor is fixedly connected to the drive wheel of the conveyor belt.

[0011] The beneficial effects of this utility model are as follows:

[0012] When in use, the above-mentioned device drives two worm gears to rotate via a worm gear, which in turn drives an eccentric disc to press against different pressure plates. This causes the connecting rod and push plate to reciprocate, thus centering and pushing the sand and gravel aggregate at the top of the conveyor belt to prevent it from falling. On the one hand, this avoids the accumulation and friction of sand and gravel aggregate on the inside of the conveyor belt, reducing abnormal wear on the belt and related components and extending the service life of the equipment. On the other hand, it prevents material accumulation and spillage, reducing the potential risks to operators when cleaning and maintaining the equipment and improving operational safety.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Refer to the instruction manual appendix Figures 1-6 A long belt conveyor for conveying sand and gravel aggregate includes a support platform 1, a conveyor belt 2, and two push plates 3. The conveyor belt 2 is located inside the support platform 1, and the two push plates 3 are located on top of the conveyor belt 2. Two connecting rods 4 are fixedly connected to the opposite sides of the two push plates 3. The ends of the connecting rods 4 away from the push plates 3 pass through both sides of the support platform 1. A pressure plate 5 is fixedly connected between the ends of the two connecting rods 4 away from the push plates 3. A first spring 13 is sleeved on the outside of the connecting rods 4, between the opposite side of the two push plates 3 and the inner wall of the support platform 1. Eccentric discs 8 are rotatably connected to both sides of the bottom of the support platform 1. The outer sides of the eccentric discs 8 are in contact with the corresponding side of the pressure plate 5. The central axis of the eccentric discs 8 is fixedly connected to the opposite side of the pressure plate 5. A worm gear 9 is fixedly connected to the bottom of the support platform 1. Two fixed plates 6 are rotatably connected to the bottom of the support platform 1. A worm 7 is rotatably connected between the interior of the two fixed plates 6. The worm gear 9 is meshed with the worm 7. The above-mentioned device has a conveyor belt 2 for conveying sand and gravel aggregate, which is set inside the support platform 1. A push plate 3 is set on top of the conveyor belt 2 to block and push the sand and gravel aggregate. A connecting rod 4 connects the push plate 3 and the pressure plate 5 to transmit motion. The pressure plate 5 is connected to the push plate 3 through the connecting rod 4 to adjust the position of the push plate 3. A first spring 13 is set outside the connecting rod 4 to provide elastic force and maintain the stability of the push plate 3 and the pressure plate 5. The eccentric disk 8 realizes the movement of the push plate 3 by rotation. The worm gear 9 and the worm 7 transmission structure control the rotation of the eccentric disk 8.

[0022] The worm gear 7 is externally fixedly connected to two first bevel gears 10, and the bottom of the support platform 1 is fixedly connected to a first motor 11. The output shaft of the first motor 11 is fixedly connected to a second bevel gear 12. The first bevel gears 10 are meshed with the second bevel gears 12. The above device, through the transmission of the first motor 11 and the gears, makes the movement of the push plate 3 more precise and efficient, and improves the working performance of the equipment.

[0023] In this device, limit rods 14 are fixedly connected to both sides of the support platform 1, and limit blocks 15 are fixedly connected to the ends of the limit rods 14 away from the support platform 1. The pressure plates 5 are slidably connected to the corresponding limit rods 14. A second spring 16 is sleeved on the outside of the limit rods 14 and between the side of the two pressure plates 5 that is far away from each other and the side of the limit block 15. The above device ensures the stability and accuracy of the pressure plates 5 during the movement process by setting the limit rods 14 and the limit blocks 15, thereby improving the safety and reliability of the equipment.

[0024] The top of the support platform 1 is fixedly connected to a U-shaped frame 17, and the bottom of the U-shaped frame 17 and above the conveyor belt 2 is fixedly connected to a dust collection box 18. The bottom of the dust collection box 18 is fixedly connected to a filter plate 19. The above device effectively reduces dust pollution in the working environment and improves the cleanliness of the working environment and the service life of the equipment by setting up the dust collection box 18 and the filter plate 19.

[0025] The top of the U-shaped frame 17 is fixedly connected to a dust pump 20, and the output end of the dust pump 20 is fixedly connected to a connecting pipe 21. The end of the connecting pipe 21 away from the dust pump 20 extends into the interior of the dust collection box 18. The output end of the dust pump 20 is fixedly connected to a dust discharge pipe 22. Through the cooperation of the dust pump 20 and the dust discharge pipe 22, the above device can efficiently suck up and discharge dust, further improving the environmental performance and working efficiency of the equipment.

[0026] The second motor 23 is fixedly connected to one side of the support platform 1. The output shaft of the second motor 23 is fixedly connected to the drive wheel of the conveyor belt 2. The above device makes the operation of the conveyor belt 2 more stable and efficient through the drive of the second motor 23, ensuring the continuous conveying of materials and the reliable operation of the equipment. Through the centralized control of the control panel, the intelligent operation and simple management of the equipment are realized, improving the operation convenience and work efficiency of the equipment.

[0027] In this embodiment, the specific implementation scenario is as follows: The control panel starts the second motor 23, which drives the drive wheel of the conveyor belt 2 to rotate via its output shaft. The conveyor belt 2 starts running, transporting sand and gravel aggregate to the designated position. The control panel starts the first motor 11, which drives the first bevel gear 10 to rotate via the second bevel gear 12. The first bevel gear 10 drives the worm gear 7 to rotate, which in turn drives the worm wheel 9 to rotate. The worm wheel 9 drives the eccentric disk 8 to rotate. The rotation of the eccentric disk 8, through contact with the pressure plate 5, pushes the connecting rod 4 and the push plate 3 to reciprocate. This motion enables the push plate 3 to... The system continuously blocks and pushes the sand and gravel aggregate on the conveyor belt 2 to ensure that the material does not fall off. The limit rod 14 and the limit block 15 limit the movement range of the pressure plate 5 to ensure the stability of the push plate 3. The first spring 13 and the second spring 16 provide additional elastic force to ensure the reset and stability of the push plate 3 and the pressure plate 5. The U-shaped frame 17 supports the dust collection box 18 and the dust collection pump 20. The dust collection pump 20 extracts the dust from the dust collection box 18 through the connecting pipe 21 and discharges it outside the device through the dust discharge pipe 22. The filter plate 19 at the bottom of the dust collection box 18 is used to filter the dust generated during the conveying process and keep the working environment clean.

[0028] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
