Description

Technical Field

[0001] This utility model relates to the field of building material processing equipment technology, and in particular to a self-cleaning stone screening machine. Background Technology

[0002] A stone screening machine is a mechanical device used to classify and screen stones of different sizes. It uses a motor to drive screening components such as vibrating screens and drum screens to generate vibrations or rotations at specific frequencies and amplitudes, causing the stones to move relative to each other on the screen surface. By utilizing the differences in the size of the screen mesh, the stones are separated according to their size. It is widely used in mining, building materials, transportation and other industries, effectively improving the quality and specification uniformity of finished stone products and meeting the needs of different engineering construction and production.

[0003] For example, a stone screening machine disclosed in Chinese Patent Publication No. CN217616041U includes a feeding assembly at one end of the machine body. The feeding assembly includes a feeding bin, and a discharge plate is hinged to the lower end of the feeding bin. The discharge plate can discharge the material in the feeding bin. A discharge rod is slidably connected to the feeding bin. When the feeding bin is full of material, it can push the discharge rod to slide away from the feeding bin. A discharge frame is fixed to the feeding bin at the position corresponding to the discharge rod. A locking plate is provided below the discharge plate on the discharge frame. The locking plate moves synchronously with the discharge frame.

[0004] During the stone screening process, impurities such as mud, dust, and gravel adhering to the surface of the stones can easily become embedded in the screen mesh during screening vibration. The accumulation of these impurities can cause screen clogging, hindering the normal passage of stones through the screen. This not only reduces screening efficiency but also increases the operating load on the equipment, shortens the service life of the screen, and affects the continuity and stability of the entire screening system. Utility Model Content

[0005] The purpose of this invention is to solve the problem that during the stone screening process, impurities such as mud, dust, and gravel adhering to the surface of the stones easily become embedded in the screen holes during screening vibration. The accumulation of these impurities leads to screen hole blockage, hindering the normal passage of stones through the screen, which not only reduces screening efficiency but also increases the operating load of the equipment and shortens the service life of the screen. Therefore, a self-cleaning stone screening machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-cleaning stone screening machine, comprising a screening chamber, stone screens symmetrically and fixedly installed inside the screening chamber, a vibrating motor fixedly installed on the top surface of the screening chamber, a feed inlet fixedly connected to one end of the top surface of the screening chamber, a discharge outlet fixedly connected to the other end of the screening chamber, a screen self-cleaning component provided at one end of one side of the stone screen, a transmission frame fixedly connected to one side of the screen self-cleaning component, heavy-duty electric push rods fixedly installed on both sides of the screening chamber, the drive end of the heavy-duty electric push rods fixedly connected to one side of the other end of the transmission frame, the screen self-cleaning component comprising an installation chamber, a cleaning roller, drive gears and a drive assembly, the cleaning roller being rotatably connected inside the installation chamber, two drive gears fixedly installed at both ends of the cleaning roller, the two drive gears being respectively connected to the drive end of the drive assembly, and a cleaning soft sleeve fixedly fitted on the outer side of the cleaning roller.

[0007] Preferably, the drive assembly includes a drive motor and a transmission gear, with the drive end of the drive motor being connected to the center of the transmission gear, and the transmission gear meshing with the drive gear.

[0008] Preferably, a side plate is fixedly installed at one end of the screening chamber, and several through holes are symmetrically opened inside the side plate, with one end of the transmission frame moving through the inside of the through holes.

[0009] Preferably, a rolling conveyor assembly is symmetrically fixedly installed inside the through hole.

[0010] Preferably, the rolling conveyor assembly includes a base and rollers. The base is fixedly mounted on the edge inside the through hole by bolts, and the rollers are rotatably connected inside the base.

[0011] Preferably, one end of the transmission frame is fixedly installed on one side of the installation chamber.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the self-rotating cleaning of the cleaning roller and the cleaning soft sleeve, combined with the material pushing design of the installation chamber, forms a dual guarantee of "sweeping + discharge", ensuring that impurities and residual stones are completely removed, so that the stone screen always maintains good screening performance, thereby improving screening accuracy and production capacity, and providing stable and reliable operation support for stone processing production.

[0014] 2. In this utility model, when the heavy-duty electric push rod drives the transmission frame to move, one end of the transmission frame will pass through the inside of the through hole. The symmetrically arranged rolling conveying components inside the through hole will limit and support the transmission frame and assist the transmission frame to pass through the through hole. The rollers will fit against the outside of the part of the transmission frame that passes through the through hole and rotate along the movement trajectory of the transmission frame, reducing the resistance of the transmission frame, reducing mechanical wear caused by friction, and extending the service life of the transmission frame and related components.

[0021] 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.

[0022] 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.

[0023] Example 1: As Figures 1-4As shown, this utility model provides a self-cleaning stone screening machine, including a screening chamber 1. Stone screens 11 are symmetrically and fixedly installed inside the screening chamber 1. A vibrating motor 12 is fixedly installed on the top surface of the screening chamber 1. A feed inlet 13 is fixedly connected to one end of the top surface of the screening chamber 1, and a discharge outlet 14 is fixedly connected to the other end of the screening chamber 1. A screen self-cleaning component 2 is provided at one end of one side of the stone screen 11. A transmission frame 3 is fixedly connected to one side of the screen self-cleaning component 2. Heavy-duty electric push rods 4 are fixedly installed on both sides of the screening chamber 1. The driving end of the heavy-duty electric push rod 4 is fixedly connected to one side of the other end of the transmission frame 3. The screen self-cleaning component 2... The assembly includes an installation chamber 21, a cleaning roller 22, a drive gear 23, and a drive assembly 24. The cleaning roller 22 is rotatably connected inside the installation chamber 21. Two drive gears 23 are fixedly installed at both ends of the cleaning roller 22 and are respectively connected to the drive end of the drive assembly 24. A cleaning soft sleeve 221 is fixedly sleeved on the outside of the cleaning roller 22. The drive assembly 24 includes a drive motor 241 and a transmission gear 242. The drive end of the drive motor 241 is connected to the center of the transmission gear 242. The transmission gear 242 meshes with the drive gear 23. One end of the transmission frame 3 is fixedly installed on one side of the installation chamber 21.

[0024] The specific settings and functions of this embodiment are described below. When it is necessary to clean the stone screen 11, the heavy-duty electric push rod 4 drives the transmission frame 3 to reset. The transmission frame 3 drives the screen self-cleaning component 2 to move along one side of the stone screen 11. At the same time, the drive motor 241 drives the transmission gear 242 to rotate, and the transmission gear 242 drives the drive gear 23 to rotate. Finally, the cleaning roller 22 and the cleaning soft sleeve 221 rotate to clean one side of the stone screen 11 and remove impurities attached to its surface. At the same time, the installation chamber 21 removes the residue remaining on the stone screen 11. The stones are pushed out from the discharge port 14. This series of automated cleaning operations significantly improves the continuity and efficiency of stone screening, effectively avoids frequent downtime maintenance caused by screen blockage, and greatly reduces manual cleaning costs and equipment wear. The self-rotating cleaning of the cleaning roller 22 and the cleaning soft sleeve 221, combined with the material pushing design of the installation chamber 21, forms a dual guarantee of "sweeping + discharge", ensuring that impurities and residual stones are completely removed, so that the stone screen 11 always maintains good screening performance, thereby improving screening accuracy and production capacity, and providing stable and reliable operation support for stone processing production.

[0025] Example 2: Figures 1-5As shown, the self-cleaning stone screening machine of this utility model includes a screening chamber 1. Stone screens 11 are symmetrically and fixedly installed inside the screening chamber 1. A vibrating motor 12 is fixedly installed on the top surface of the screening chamber 1. A feed inlet 13 is fixedly connected to one end of the top surface of the screening chamber 1, and a discharge outlet 14 is fixedly connected to the other end of the screening chamber 1. A screen self-cleaning component 2 is provided at one end of one side of the stone screen 11. A transmission frame 3 is fixedly connected to one side of the screen self-cleaning component 2. Heavy-duty electric push rods 4 are fixedly installed on both sides of the screening chamber 1. The driving end of the heavy-duty electric push rod 4 is fixedly connected to one side of the other end of the transmission frame 3. The screen self-cleaning component 2 includes an installation chamber 21, a cleaning roller 22, a drive gear 23, and a drive assembly 24. The cleaning roller 22 is rotatably connected inside the mounting chamber 21. Two drive gears 23 are fixedly installed at both ends of the cleaning roller 22. The two drive gears 23 are respectively connected to the drive end of the drive assembly 24. A cleaning soft sleeve 221 is fixedly sleeved on the outside of the cleaning roller 22. A side plate 15 is fixedly installed at one end of the screening chamber 1. Several through holes 151 are symmetrically opened inside the side plate 15. One end of the transmission frame 3 is movably inserted through the inside of the through holes 151. A rolling conveyor assembly 5 is symmetrically fixedly installed inside the through holes 151. The rolling conveyor assembly 5 includes a base 51 and a roller 52. The base 51 is fixedly installed at the edge of the inside of the through holes 151 by bolts. The roller 52 is rotatably connected inside the base 51.

[0026] The overall effect of this embodiment is that when the heavy-duty electric push rod 4 drives the transmission frame 3, one end of the transmission frame 3 passes through the interior of the through hole 151. The symmetrically arranged rolling conveying components 5 inside the through hole 151 provide limiting support for the transmission frame 3 and assist the transmission frame 3 in passing through the through hole 151. The rollers 52 fit against the outer side of the portion of the transmission frame 3 that passes through the through hole 151 and rotate along the movement trajectory of the transmission frame 3, reducing the resistance experienced by the transmission frame 3, reducing mechanical wear caused by friction, extending the service life of the transmission frame 3 and related components, and reducing equipment maintenance costs. At the same time, the precise limiting support ensures the stability of the movement path of the transmission frame 3 and avoids deviation in the operation of the screen self-cleaning component 2 due to offset.

[0027] The device is used and works as follows: The heavy-duty electric push rod 4 drives the transmission frame 3 to reset. The transmission frame 3 drives the screen self-cleaning component 2 to move along one side of the stone screen 11. At the same time, the drive motor 241 drives the transmission gear 242 to rotate. The transmission gear 242 drives the drive gear 23 to rotate. Finally, the cleaning roller 22 and the cleaning soft sleeve 221 rotate to clean one side of the stone screen 11 and remove impurities attached to its surface. At the same time, the installation chamber 21 pushes out the stones remaining on the stone screen 11 from the discharge port 14.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the 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 this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
