Description

Technical Field

[0001] This utility model relates to the technical field of sand and gravel processing equipment, and in particular to a tuff-based manufactured sand and gravel powder separation and screening device. Background Technology

[0002] Sand and gravel processing equipment refers to specialized machinery used to crush, screen, shape, and wash natural or artificial rocks to produce sand and gravel aggregates that meet the requirements of construction, road, bridge and other engineering projects. This type of equipment is widely used in mining, building materials, transportation infrastructure construction and other fields. It is a key link in the production of modern concrete, asphalt mixtures, dry mortar and other building materials. With the rapid development of infrastructure construction and the increasing depletion of natural sand resources, manufactured sand has become the main source of aggregates to replace natural sand.

[0003] In existing technologies, tuff manufactured sand and gravel powder separation and screening equipment lacks pre-crushing function. Most screening equipment directly screens the crushed sand and gravel. When there are lumps or agglomerates in the material, it is easy to cause screen blockage, reduce screening efficiency, and affect the continuous operation capability of the equipment. The screen plates are fixedly installed, making disassembly and maintenance difficult. The screens of traditional equipment are mostly installed by bolts or welding. When the screen is worn or it is necessary to replace the screen plate with a different mesh size to adapt to different particle size requirements, the disassembly and installation process is cumbersome, time-consuming and labor-intensive, affecting production efficiency, and thus requiring improvement.

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.

[0021] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a tuff manufactured sand and gravel powder separation and screening device, including a support frame 1 and a screening box 2. A controller 3 is fixedly installed on the side of the screening box 2, a feed hopper 4 is fixedly installed on the top of the screening box 2, a discharge pipe 5 is fixedly installed on the bottom of the screening box 2, an installation frame 6 is provided on the inner side of the screening box 2, a screening plate 7 is provided on the inner side of the installation frame 6, a discharge port 8 is opened on the side of the screening box 2, an impact block 9 is fixedly connected to the lower surface of the screening plate 7, and an electric... Machine 10, motor 10 output end is fixedly connected to irregular block 11, screening box 2 inner side is fixedly connected to mounting sleeve 12, mounting sleeve 12 internally is slidably connected to telescopic rod 13, mounting sleeve 12 internally is provided with tension spring 14, screening plate 7 side is fixedly connected to insert block 15, mounting frame 6 side is provided with slot 16, mounting frame 6 surface is fixedly installed with limit sleeve 17, limit sleeve 17 internally is slidably connected to limit rod 18, insert block 15 side is provided with limit hole 19, limit rod 18 surface is provided with limit hole 19. A limiting disc 20 is fixedly connected to the surface of the limiting rod 18, and a tension spring 21 is sleeved on the surface of the limiting rod 18. A maintenance door 22 is hinged to the side of the screening box 2. Crushing rod 1 23 and crushing rod 24 are rotatably connected to the inner side of the feed hopper 4. Gear 1 25 is fixedly connected to one end of crushing rod 1 23, and gear 26 is fixedly connected to one end of crushing rod 24. Motor 27 is fixedly installed on the side of the feed hopper 4. The surface of the irregular block 11 abuts against the lower surface of the impact block 9. One end of the telescopic rod 13 is fixed to the lower surface of the mounting frame 6. The connection is as follows: one end of tension spring 14 is fixedly connected to the inner side of mounting sleeve 12, the other end of tension spring 14 is fixedly connected to one end of telescopic rod 13, insert block 15 is slidably connected to slot 16, limit rod 18 is slidably connected to limit hole 19, one end of tension spring 21 is fixedly connected to the inner side of limit sleeve 17, one end of tension spring 21 is fixedly connected to the side of limit plate 20, gear one 25 and gear two 26 mesh and drive each other, and the output end of motor two 27 is fixedly connected to one end of crushing rod one 23.

[0022] In this embodiment, during use, manufactured tuff sand is added from the feed hopper 4. Then, motor 27 is started, and its output end drives crushing rod 23 to rotate. Through the meshing transmission of gear 25 and gear 26, crushing rod 24 rotates in the opposite direction to crushing rod 23, squeezing and crushing the incoming sand and gravel material, breaking up clumps, preventing large particles or agglomerates from clogging the screening plate 7, and ensuring that the material enters the screening area evenly. Then, motor 10 is started to drive the shaped block 11 to rotate. The surface of the shaped block 11 periodically pushes against the impact block 9, causing the screening plate 7 to move up and down reciprocally. At the same time, the telescopic rod 13 slides in the mounting sleeve 12, and the tension... Spring 14 is compressed or stretched to provide elastic restoring force, ensuring stable vibration of screen plate 7. Material is screened on screen plate 7. Fine sand that meets the particle size requirements falls into the bottom of screen box 2 through screen plate 7 and is discharged through discharge pipe 5. Larger particles move along screen plate 7 towards discharge port 8 and are discharged from discharge port 8 for further crushing or processing. When screen plate 7 needs to be cleaned or replaced, first open inspection door 22, then pull limit rod 18 outward so that its end is disengaged from limit hole 19 on insert block 15, compress tension spring 21, and then pull screen plate 7 horizontally out through insert block 15 along slot 16 to achieve quick disassembly and maintenance.

[0023] Example 2: As Figures 1-5 As shown, a conveyor box 28 is fixedly installed on the lower surface of the discharge pipe 5. An auger 29 is rotatably connected inside the conveyor box 28. A motor 30 is fixedly installed on the side of the conveyor box 28. A conveyor pipe 31 is fixedly installed on the surface of the conveyor box 28. The output end of the motor 30 is fixedly connected to one end of the auger 29.

[0024] In this embodiment, qualified fine sand discharged from the discharge pipe 5 enters the conveying box 28. The motor 30 is started, and its output end drives the auger 29 to rotate, pushing the fine sand in the conveying box 28 to the conveying pipe 31. The screened manufactured sand is then conveyed to a designated location or storage container through the conveying pipe 31, realizing automatic and continuous discharge, avoiding material accumulation, and improving production efficiency. The entire equipment is centrally controlled by the controller 3 to start and stop each motor. It is easy to operate and runs stably, effectively solving the problems of high stone powder content, easy agglomeration, and easy screen clogging in tuff manufactured sand, and realizing efficient and continuous stone powder separation and screening operations.

[0025] The working principle of this embodiment is as follows: During use, manufactured tuff sand is added to the equipment through the feed hopper 4. Then, motor 27 is started, and its output end drives crushing rod 23 to rotate. At the same time, through the meshing transmission of gear 25 and gear 26, crushing rod 24 rotates in the opposite direction, which initially crushes and disperses the material entering the feed hopper 4 to prevent lumpy material from clogging the screen plate 7. The pre-treated material falls into the screening box 2 and onto the screen plate 7 in the mounting frame 6. Then, motor 10 is started, and its output end drives the shaped block 11 to rotate. The shaped block 11 periodically pushes the impact block 9, causing the screen plate 7 to vibrate up and down in the mounting frame 6. During this process, the telescopic rod 13 slides in the mounting sleeve 12, and the tension spring 14 provides a restoring force to ensure stable vibration of the screen plate 7. The material is screened by the vibration of the screening plate 7. Fine sand that meets the particle size requirements falls through the screen into the bottom of the screening box 2 and is discharged through the discharge pipe 5. Larger particles move along the screening plate 7 to the discharge port 8 on the side for further processing or re-crushing. The qualified fine sand discharged from the discharge pipe 5 enters the conveying box 28. Then, the motor 30 is started, and its output end drives the auger 29 to rotate, pushing the fine sand along the conveying box 28 and conveying it through the conveying pipe 31 to the designated position or storage container, realizing automatic continuous discharge, avoiding material accumulation, and ensuring the continuity and efficiency of the production process. When it is necessary to clean or replace the screening plate 7, the operator can open the inspection door 22 on the side of the screening box 2, pull the limit rod 18 in the limit sleeve 17, so that its end is disengaged from the limit hole 19 on the insert block 15, compress the tension spring 21, and then pull the screening plate 7 horizontally out through the insert block 15 along the slot 16 to complete the quick disassembly and maintenance of the screening plate 7 without the need for tools.

[0026] 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.
