Abstract
Description
Technical Field
[0001] This utility model belongs to the field of construction equipment, and specifically relates to a multi-layer screening structure of a construction sand and gravel screening machine. Background Technology
[0002] Construction gravel screening machines are specialized mechanical devices used in the construction industry to classify and screen bulk materials such as gravel. Currently, some construction gravel screening machines have shortcomings in actual operation. During the screening process, due to the relatively simple internal structure of the equipment, it is difficult to ensure that the gravel is evenly distributed on the screen, resulting in low utilization of some areas of the screen and reduced screening efficiency. At the same time, a single screen is prone to clogging when faced with a large amount of gravel of different particle sizes, as larger particles may accumulate at the screen openings, hindering the passage of finer particles. This is mainly due to the lack of a multi-stage, step-by-step screening mechanism. To address screen clogging, the conventional approach is to increase vibration intensity, but this may affect the overall stability of the equipment, leading to premature wear of equipment components and increased noise pollution. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-layer screening structure for a construction sand and gravel screening machine, so as to solve the problems mentioned in the background technology.
[0004] This utility model is achieved through the following technical solution: a multi-layer screening structure for a building sand and gravel screening machine, comprising: a base frame assembly, a frame body assembly, and a screening assembly. The frame body assembly for the screening assembly is installed on the upper surface of the base frame assembly. The base frame assembly includes a base frame body and a buffer component. The buffer component is installed on the upper surface of the base frame body. The frame body assembly includes a vibrating component, a mounting component, and a frame plate. The screening assembly includes a screening plate for screening. Multiple screening plates are installed between the frame plates through the mounting component. The mounting component includes mounting plate one and mounting plate two. The cross-sectional interface of mounting plate one is L-shaped. Multiple layers of mounting plate one are symmetrically installed on the inner surfaces of the two frame plates. There are two mounting plates one in each layer. Mounting plate two is installed between the two mounting plates one. Mounting plate two is T-shaped. The mounting component is inclined and installed on the inner surface of the frame plate. The rear surfaces of the two frame plates are designed to be open. Multiple discharge plates are evenly installed on the rear surfaces of the two frame plates. The number of discharge plates matches the number of layers of the mounting component.
[0005] In a preferred embodiment, four support legs are integrally formed on the lower surface of the base frame body, and multiple buffers are evenly installed on the left and right edges of the upper surface of the base frame body. The buffers are spring buffers, and the vibration components include a mounting frame, a reinforcing frame, and a vibration frame.
[0006] In a preferred embodiment, a mounting frame is installed above the base frame body via a buffer. A vibrator is mounted on the front edge of the upper surface of the mounting frame via a vibrating frame. A frame plate is installed on the left and right edges of the upper surface of the mounting frame, and a baffle is integrally formed on the front side between the two frame plates. A reinforcing frame is installed obliquely on the front edge of the upper surface of the mounting frame, and the end of the reinforcing frame away from the mounting frame is connected to the front surface of the baffle. During use, the buffer in the base frame assembly can effectively reduce the vibration impact during the screening process and improve the stability of equipment operation. At the same time, the vibrating component, mounting component and frame plate of the frame assembly cooperate with each other to realize multi-level grading screening of construction gravel, which not only improves screening efficiency and accuracy, but also adapts to the separation needs of gravel of different particle sizes.
[0007] In a preferred embodiment, the inner surface of the discharge plate is parallel and aligned with the surface of the mounting component. A screening plate is installed at an angle between the two frame plates via the mounting component. The number of screening plates matches the number of mounting components. Screening holes are formed on the surface of each screening plate. The screening holes on the surfaces of multiple screening plates are different. In use, by setting multiple screening plates between the frame plates using the mounting component, construction gravel can be screened step by step and in a fine layer. Multiple gravel particles of different sizes can be separated at one time, greatly improving the efficiency of the screening operation.
[0008] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a base frame assembly, a frame assembly for screening is installed on the upper surface of the base frame assembly. The base frame assembly includes a base frame body and a buffer component. The upper surface of the base frame body is equipped with a buffer component. The frame assembly includes a vibrating component, a mounting component, and a frame plate. During use, the buffer component in the base frame assembly can effectively reduce the vibration and impact during the screening process and improve the stability of equipment operation. At the same time, the vibrating component, the mounting component, and the frame plate of the frame assembly cooperate with each other to achieve multi-level grading screening of construction gravel, which not only improves screening efficiency and accuracy but also adapts to the separation needs of gravel of different particle sizes.
[0009] 2. By setting up a screening component, which includes screening plates for screening, multiple screening plates are installed between the frames via mounting brackets. In use, by using the mounting brackets to set up multiple screening plates between the frames, construction gravel can be screened step by step and in a fine layered manner. Multiple gravel of different particle sizes can be separated at one time, which greatly improves the efficiency of screening operations. Attached Figure Description

Detailed Implementation
[0015] 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.
[0016] Please see Figures 1 to 3 As the first embodiment of this utility model: a multi-layer screening structure of a building sand and gravel screening machine, including: a base frame assembly, a frame body assembly and a screening assembly. The frame body assembly for the screening assembly is installed on the upper surface of the base frame assembly. The base frame assembly includes a base frame body 100 and a buffer member 110. The buffer member 110 is installed on the upper surface of the base frame body 100. The frame body assembly includes a vibrating member, an installation member and a frame plate 230. The screening assembly includes a screening plate 320 for screening. Multiple screening plates 320 are installed between the frame plates 230 through the installation member. The mounting components include mounting plate 300 and mounting plate 310. The cross-sectional interface of mounting plate 300 is L-shaped. Multiple layers of mounting plate 300 are symmetrically installed on the inner surfaces of the two frame plates 230. There are two mounting plates 300 in each layer. Mounting plate 310 is installed between the two mounting plates 300. Mounting plate 310 is T-shaped. The mounting components are installed on the inner surface of the frame plates 230 with an inclined structure. The rear surfaces of the two frame plates 230 are designed to be open. Multiple discharge plates 240 are evenly installed on the rear surfaces of the two frame plates 230. The number of discharge plates 240 matches the number of layers of the mounting components. Four support legs are integrally formed on the lower surface of the base frame body 100. Multiple buffers 110 are evenly installed on the left and right edges of the upper surface of the base frame body 100. The buffers 110 are spring buffers. The vibration components include the mounting frame 200, the reinforcing frame 220 and the vibration frame 210. A mounting frame 200 is installed above the base frame body 100 via a buffer 110. A vibrator is installed on the front edge of the upper surface of the mounting frame 200 via a vibrating frame 210. A frame plate 230 is installed on the left and right edges of the upper surface of the mounting frame 200 respectively. A baffle is integrally formed on the front side between the two frame plates 230. A reinforcing frame 220 is installed obliquely on the front edge of the upper surface of the mounting frame 200. The end of the reinforcing frame 220 away from the mounting frame 200 is connected to the front surface of the baffle. In use, the user first prepares the screening plate 320 inside the screening component, and then installs the screening plate 320 on the upper surface of the mounting component. During installation, the screening plate 320 is placed on the upper surface of two mounting plates 300 and one mounting plate 310. This completes the installation of the screening plate 320. After installation, the user can place the construction gravel to be screened onto the surface of the uppermost screening plate 320. After placement, the user can then start the vibrator on the upper surface of the vibrating frame 210 to vibrate the screening component and the frame assembly, thereby causing the uppermost layer of construction gravel to be screened. The gravel is screened through the screening plate 320, and the construction gravel is screened into the surface of the next screening plate 320. At this time, the construction gravel that is not screened in the upper layer will enter the discharge plate 240 through tilting vibration and be collected. Similarly, the multi-layer screening plate 320 will screen the construction gravel. During use, the buffer 110 in the base frame assembly can effectively reduce the vibration and impact during the screening process and improve the stability of equipment operation. At the same time, the vibrating components and installation components of the frame assembly cooperate with the frame plate 230 to realize multi-layer grading screening of construction gravel, which not only improves screening efficiency and accuracy, but also adapts to the separation needs of gravel with different particle sizes.
[0017] Please see Figures 1 to 3As a second embodiment of this utility model: the inner surface of the discharge plate 240 is parallel and aligned with the surface of the mounting component. A screening plate 320 is installed at an angle between the two frame plates 230 through the mounting component. The number of screening plates 320 is matched with the number of mounting components. Screening holes 321 are opened on the surface of the screening plate 320. The screening holes 321 on the surfaces of multiple screening plates 320 are different. In use, when screening construction gravel through the operation steps of the first embodiment, the construction gravel falls through the screening holes 321 on the surface of the top screening plate 320, and then falls into the surface of the third screening plate 320 through the same principle, and then the fourth layer. The construction gravel on the surfaces of the four screening plates 320 will reach the surface of the corresponding discharge plate 240 and be discharged through the discharge plate 240. As can be seen from the attached drawings, the discharge ports of the discharge plates 240 are not in the same position. At this time, the user can set the collection device in different positions to achieve multi-layer screening of construction gravel. Since multi-layer screening plates 320 are set between the frame plates 230 using the mounting parts, construction gravel can be screened step by step and in a fine layer, and multiple gravel of different particle sizes can be separated at one time, which greatly improves the efficiency of screening operation.
[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
