Description

Technical Field

[0001] This utility model relates to the field of sand and soil production technology, and in particular to a soil removal vibrating screen for manufactured sand production. Background Technology

[0002] Manufactured sand, also known as "manufactured sand and gravel," refers to artificial sand and gravel that is produced by processing raw materials such as rocks, tailings, waste rock, and construction waste through specialized crushing and screening equipment. The final particle size meets the standards for construction sand, making it an important alternative to natural sand.

[0003] An investigation revealed that a Chinese utility model patent, CN220144043U, discloses a vibrating screening device for manufactured sand. The device includes a screening box; a dust removal device installed on the dust removal box; a feed inlet at the top of the structural cavity; conveyor belts installed on both sides of the inner wall of the structural cavity; an air outlet box installed at the end of the air duct; a dust removal chamber at the other end of the dust removal box; a through-hole at the bottom of the inner wall of the structural cavity; a screening device installed on the screening box; a screening frame fixed to the top of the slider; a first screen installed on the upper part of the inner wall of both sides of the screening frame; and a second screen installed on the lower part of the inner wall of both sides of the screening frame. Through the combined action of the dust removal device and the screening device, not only is dust removed from the sand and gravel particles to be screened, ensuring the environmental quality of the workshop, but the required sand and gravel particles are also screened, ensuring the requirements of the screening work are met.

[0004] When used by users, the above-mentioned patent has low screening efficiency and poor operational stability. In terms of screening efficiency, local accumulation of manufactured sand raw materials is prone to occur when they enter the screen area, resulting in the waste of the effective filtration area of ​​the screen. In some places, the material accumulation is too thick, which can also hinder the separation of soil impurities, reduce the screening volume per unit time, and fail to meet the needs of large-scale production of manufactured sand. Moreover, the purity of the manufactured sand after screening is difficult to guarantee, which brings quality risks to subsequent production processes.

[0005] Therefore, there is a particular need for a soil removal vibrating screen for manufactured sand production. Utility Model Content

[0006] The purpose of this invention is to provide a soil removal vibrating screen for manufactured sand production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a soil removal vibrating screen for manufactured sand production, comprising a main body of the device, a support plate fixedly connected to the upper surface of the main body of the device, a collection shell inserted into the inner ring surface of the support plate, and a screening mechanism installed on the side surface of the support plate.

[0008] The screening mechanism includes a main fixed frame mounted on a support plate. A guide shell is installed on the upper surface of the main fixed frame. A connecting frame is fixedly connected to one side of the main fixed frame. A protective shell is locked to the inner ring surface of the connecting frame. A connecting block is fixedly connected to the inner ring surface of the protective shell. A motor is fixedly connected to one side of the connecting block. An irregular weight block is fixedly sleeved on the top of the motor's output shaft. A filter screen is inserted into the inner ring surface of the main fixed frame. A handle is fixedly connected to one side of the filter screen. A positioning rod is inserted into the inner ring surface of the main fixed frame. A guide plate is fixedly connected to the inner ring surface of the guide shell.

[0009] Preferably, the upper surface of the protective shell has a through-hole for heat dissipation, and the number of heat dissipation openings is multiple.

[0010] Preferably, the motor is connected to the protective shell via a connecting block, and the connecting block is symmetrically arranged with the vertical center line of the motor as the axis of symmetry.

[0011] Preferably, the inner ring surface of the protective shell is fitted with a protective shaft, and the protective shaft and the output shaft of the motor are matched in size.

[0012] Preferably, the inner surface of the protective shell is provided with a second snap-fit ​​opening, and the second snap-fit ​​opening and the protective shaft are structurally compatible.

[0013] Preferably, the bottom surface of the device body is fixedly connected to a support foot, and the support foot is symmetrically arranged with the vertical center line of the device body as the axis of symmetry.

[0014] Preferably, the inner surface of the connecting frame has a first snap-fit ​​opening, and the size of the first snap-fit ​​opening matches that of the protective shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The filter screen is installed inside the main fixed frame via a limit-locking interlocking method, and a handle is fixedly connected to one side. When the screen becomes clogged or worn, workers can quickly remove it for cleaning or replacement without using complicated tools, simply by pulling the handle, significantly shortening maintenance time. Simultaneously, the protective shell and connecting frame are locked together via a first snap-fit ​​opening, and the motor is fixed inside the protective shell via a connecting block. If the motor malfunctions, the protective shell can be easily disassembled for inspection or replacement, reducing equipment downtime for maintenance, minimizing production losses due to equipment failure, and indirectly saving on operating and maintenance costs.

[0017] 2. The guide plate, fixedly connected to the inner ring of the guide shell, guides the manufactured sand into the filter screen area evenly and orderly, preventing material accumulation on the screen and affecting the screening effect. This ensures full utilization of the screen area and increases the screening volume per unit time. Regarding operational stability, a protective shaft is installed at the motor output shaft, and this protective shaft fits into the second snap-fit ​​opening structure on the protective shell, providing good support and limiting for the motor output shaft, reducing vibration during motor operation. Simultaneously, the motor is connected to the protective shell via symmetrically arranged connecting blocks, further enhancing the stability of the motor installation and preventing instability in the entire screening mechanism due to motor vibration. Furthermore, the irregularly shaped load-bearing block fixedly fitted at the top of the motor output shaft generates a stable vibration frequency, ensuring efficient separation of mud and impurities from the manufactured sand by the filter screen, guaranteeing the purity of the screened manufactured sand, and providing high-quality raw materials for subsequent production stages.

[0023] 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.

[0024] Please see Figure 1-4This utility model provides a technical solution: a soil removal vibrating screen for manufactured sand production, including a device body 1, a support plate 4 fixedly connected to the upper surface of the device body 1, a collection shell 5 being inserted into the inner ring surface of the support plate 4, and a screening mechanism 3 being installed on the side surface of the support plate 4.

[0025] The screening mechanism 3 includes a main fixed frame 301, which is mounted on a support plate 4. A guide shell 314 is installed on the upper surface of the main fixed frame 301. A connecting frame 302 is fixedly connected to one side of the main fixed frame 301. A protective shell 303 is limited and snapped onto the inner ring surface of the connecting frame 302. A connecting block 304 is fixedly connected to the inner ring surface of the protective shell 303. A motor 305 is fixedly connected to one side of the connecting block 304. An irregular load block 307 is fixedly sleeved on the top of the output shaft of the motor 305. A filter screen 312 is limited and inserted into the inner ring surface of the main fixed frame 301. A handle 313 is fixedly connected to one side of the filter screen 312. A positioning rod 311 is limited and inserted into the inner ring surface of the main fixed frame 301. A guide plate 315 is fixedly connected to the inner ring surface of the guide shell 314.

[0026] Furthermore, the upper surface of the protective shell 303 is provided with heat dissipation openings 306, and there are multiple heat dissipation openings 306. The heat dissipation openings 306 can quickly dissipate the heat generated by the motor 305 during operation to the outside of the protective shell 303, so as to avoid the performance degradation or failure of the motor 305 due to long-term high temperature operation, extend the service life of the motor 305, and at the same time ensure the continuous and stable operation of the vibrating screen to meet the needs of continuous production of manufactured sand.

[0027] Furthermore, the motor 305 is connected to the protective shell 303 via the connecting block 304, and the connecting block 304 is symmetrically arranged with the vertical center line of the motor 305 as the axis of symmetry. The symmetrical connecting block 304 can keep the motor 305 in force balance within the protective shell 303, avoid additional shaking caused by the center of gravity shift during the operation of the motor 305, reduce the vibration impact on the protective shell 303 and the connecting frame 302, improve the operational stability of the entire screening mechanism 3, and thus ensure that the vibration frequency of the filter screen 312 is uniform and improve the soil removal screening effect of the manufactured sand.

[0028] Furthermore, a protective shaft 309 is fixedly engaged on the inner ring surface of the protective shell 303, and the protective shaft 309 and the output shaft of the motor 305 are matched in size. The protective shaft 309 can support and protect the output shaft of the motor 305, preventing the output shaft of the motor 305 from bending or wearing due to uneven force when driving the irregular load block 307 to rotate. This ensures that the output shaft can stably transmit power and that the vibration effect generated by the irregular load block 307 can accurately act on the filter screen 312, avoiding the impact of output shaft failure on screening efficiency.

[0029] Furthermore, the inner surface of the protective housing 303 is provided with a second snap-fit ​​opening 310, and the structure between the second snap-fit ​​opening 310 and the protective shaft 309 is mutually fitted. The second snap-fit ​​opening 310 can achieve precise positioning and installation of the protective shaft 309, preventing the protective shaft 309 from shifting or loosening during the operation of the motor 305, ensuring that the protective shaft 309 always remains coaxial with the output shaft of the motor 305, further enhancing the support stability of the output shaft, and also facilitating the disassembly and replacement of the protective shaft 309 in the future, reducing maintenance difficulty.

[0030] Furthermore, a support foot 2 is fixedly connected to the bottom surface of the main body 1 of the device, and the support foot 2 is symmetrically arranged with the vertical center line of the main body 1 of the device as the axis of symmetry. The symmetrical support foot 2 can provide a stable support foundation for the entire vibrating screen, evenly distribute the weight of the equipment to the ground, avoid tilting or displacement caused by vibration during the operation of the equipment, reduce the impact of equipment vibration on the ground, reduce damage to the ground structure of the production site, and ensure the safety of the production environment.

[0031] Furthermore, the inner surface of the connecting frame 302 is provided with a first snap-fit ​​opening 308, and the size of the first snap-fit ​​opening 308 and the protective shell 303 are matched. The first snap-fit ​​opening 308 enables the protective shell 303 to quickly and accurately connect with the connecting frame 302, ensuring that the installation position of the protective shell 303 is accurate and avoiding misalignment of the protective shell 303, which would cause the motor 305 and the screening mechanism 3 to be out of coordination. At the same time, the snap-fit ​​structure also facilitates the later disassembly of the protective shell 303 to inspect and maintain internal components such as the motor 305 and the protective shaft 309, reducing equipment downtime and improving operation and maintenance efficiency.

[0032] Working principle: When a user needs to use a vibrating screen for removing soil in the production of manufactured sand, the first step is to check the installation status of each component. Ensure that the filter screen 312 is stably installed in the inner ring of the main fixed frame 301 via a limit-locking insertion method, and that the positioning rod 311 is inserted into the inner ring of the main fixed frame 301 to position and fix the filter screen 312. The protective shell 303 is limited and locked onto the connecting frame 302 via the first locking opening 308 in the inner ring of the connecting frame 302. The protective shaft 309 is limited and locked into the protective shell 303 via the second locking opening 310 in the inner ring of the protective shell 303, and the protective shaft 309 is precisely matched with the output shaft of the motor 305. Simultaneously, confirm that the collecting shell 5 is limited and inserted into the inner ring of the support plate 4, and that the support feet 2 at the bottom of the main body 1 are stably in contact with the ground, providing a stable support foundation for equipment operation.

[0033] After the equipment is started, the manufactured sand raw material to be removed is transported to the guide shell 314 of the screening mechanism 3. The guide plate 315 fixed in the inner ring of the guide shell 314 guides the raw material, so that the manufactured sand flows evenly and orderly to the surface of the filter screen 312 below, avoiding local accumulation of raw material on the filter screen 312, and ensuring that the effective filtration area of ​​the screen is fully utilized. The motor 305 is started. The motor 305 is connected to the protective shell 303 through the connecting block 304. The connecting block 304 is symmetrically set with the vertical center line of the motor 305 as the axis of symmetry to ensure stable operation of the motor 305. The output shaft of the motor 305 drives the irregular load block 307 fixed at the top to rotate at high speed. The centrifugal force generated by the irregular load block 307 causes the main fixed frame 301 and the filter screen 312 inside to vibrate stably.

[0034] During this process, the protective shaft 309 supports and limits the output shaft of the motor 305, reducing output shaft wobbling. Multiple heat dissipation openings 306 on the upper surface of the protective shell 303 promptly dissipate the heat generated by the motor 305, preventing overheating failure. Under the vibration of the filter screen 312, manufactured sand particles meeting the required particle size fall through the screen into the collection shell 5 below for collection, while soil and impurities remain on the surface of the filter screen 312, completing the soil removal and screening process. When the screening operation is complete or maintenance is required, first turn off the motor 305, and wait until the equipment has completely stopped vibrating. If the filter screen 312 needs to be cleaned or replaced, the positioning rod 311 can be pulled out, and the handle 313 on one side of the filter screen 312 can be pulled to remove the filter screen 312 from the inner ring of the main fixing frame 301. Clean the residual soil and impurities on the surface or replace it with a new screen. If the motor 305 malfunctions, the protective shell 303 can be removed from the first snap-fit ​​opening 308 of the connecting frame 302. After disassembling the protective shaft 309, the motor 305 can be repaired or replaced. At the same time, the collecting shell 5 can be pulled out from the inner ring of the support plate 4 to pour out the qualified manufactured sand after soil removal collected inside, thus completing one screening operation cycle.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
