Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a mobile vibrating screening device. Background Technology

[0002] In mining operations, screening equipment is needed to separate impurities and unwanted solids from the raw ore, thereby improving the purity and quality of the ore.

[0003] To maintain stability, existing screening equipment in mines typically does not have moving parts, resulting in low flexibility in the movement of the overall screening equipment. In addition, due to the weight of the ore, the support strength of the screening support components of existing screening equipment is often insufficient, which is not conducive to long-term screening of large pieces of material.

[0004] Existing ore block screening methods used in mines have the following drawbacks: During ore screening operations, the heavy weight of the ore leads to high fatigue and damage rates on the machine frame, and the screening device is difficult to move flexibly within the work area, resulting in significant limitations in screening operations. Therefore, we propose a mobile vibrating screening device. Utility Model Content

[0005] The main objective of this invention is to provide a mobile vibrating screening device that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A mobile vibrating screening device includes a steel frame, a frame and a moving component, and also includes spring shock absorbers, crossbeams, inclined beams and screen plates. The frame is set on the top of the steel frame, and the bottom two sides of the frame are respectively connected to the bottom steel frame of the spring shock absorbers. The moving component is set at the bottom of the steel frame, and a vibrating motor is fixedly installed on the top of the frame.

[0008] The moving assembly includes a crossbar, a longitudinal bar, wheels, and hydraulic cylinders, with four sets of hydraulic cylinders.

[0009] Furthermore, longitudinal bars are provided on both sides of the bottom of the steel frame, and transverse bars are provided at both ends between the longitudinal bars. The transverse bars are welded and fixed to the longitudinal bars. The wheels are provided on both sides of the steel frame, and the rotation shaft of the wheels is rotatably connected to the longitudinal bars through bearing seats.

[0010] Furthermore, lifting slots are provided on both sides of the bottom of the steel frame, and four sets of hydraulic cylinders are fixedly installed in the top of the lifting slots. The output ends of the bottom of the hydraulic cylinders are fixedly connected to both ends of the crossbar.

[0011] Furthermore, multiple sets of crossbeams are provided, and the crossbeams are welded and fixed at equal intervals along the bottom of the frame. Multiple sets of inclined beams are provided, and they are arranged longitudinally at equal intervals along the top of the crossbeams. The inclined beams are welded and fixed to the crossbeams. The screen plate is set inside the frame, and the screen plate is riveted to the inclined beams with bolts.

[0012] Furthermore, a feed hopper is installed at one end of the top of the frame, and a guide plate is provided at the bottom of the frame.

[0013] Compared with the prior art, this utility model has the following beneficial effects: The assembly consisting of a steel frame, a frame, a moving component, spring shock absorbers, crossbeams, inclined beams, and a screen plate provides a mobile vibrating screening mechanism with high support strength for the ore. The steel frame provides a high-stability support structure for the bottom of the vibrating screen frame. The crossbeams and inclined beams provide high-strength screening support at the bottom of the frame, making the overall screening structure suitable for screening heavy ore blocks. The moving component provides a liftable moving mechanism for the bottom of the steel frame. During operation, the moving component rises, and the high-strength steel frame supports the entire device. When movement is needed, the moving component descends and supports the entire device. The wheels pull the entire device for movement. This solves the problems of high fatigue and damage rate of the machine frame and difficulty in moving the screening device flexibly in the work area, which are common in existing mining vibrating screening devices during ore screening operations due to the large weight of the ore.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a mobile vibrating screening device includes a steel frame 1, a frame 2, and a moving component 3. It also includes spring shock absorbers 4, crossbeams 5, inclined beams 6, and a screen plate 9. The frame 2 is located on top of the steel frame 1. The bottom sides of the frame 2 are respectively connected to the bottom of the steel frame 1 via spring shock absorbers 4. The moving component 3 is located at the bottom of the steel frame 1. A vibrating motor 7 is fixedly installed on the top of the frame 2. The moving component 3 includes a crossbar 301, a longitudinal bar 302, wheels 303, and hydraulic cylinders 304. Four sets of hydraulic cylinders 304 are provided.

[0021] The steel frame 1 has longitudinal bars 302 on both sides of its bottom, and cross bars 301 at both ends between the longitudinal bars 302. The cross bars 301 are welded and fixed to the longitudinal bars 302. The wheels 303 are located on both sides of the steel frame 1, and the rotation shaft of the wheels 303 is rotatably connected to the longitudinal bars 302 through bearing seats.

[0022] The steel frame 1 has lifting slots 12 on both sides of the bottom. Four sets of hydraulic cylinders 304 are fixedly installed in the top of the lifting slots 12. The output ends of the bottom of the hydraulic cylinders 304 are fixedly connected to the two ends of the crossbar 301.

[0023] The frame 2 has multiple sets of crossbeams 5, which are welded and fixed at equal intervals along the bottom of the frame 2. The frame 2 also has multiple sets of inclined beams 6, which are arranged longitudinally at equal intervals along the top of the crossbeams 5 and are welded and fixed to the crossbeams 5. The screen plate 9 is set inside the frame 2 and is riveted to the inclined beams 6 with bolts.

[0024] The frame 2 has a feeding hopper 10 installed at one end of its top and a guide plate 11 at its bottom.

[0025] It should be noted that this utility model is a mobile vibrating screening device. During movement, the crossbar 301 is pushed down by the hydraulic cylinder 304, so that the wheel 303 lands on the ground. The wheel 303 provides rolling support for the entire device. The steel frame 1 is towed by vehicles at the construction site, so that the entire vibrating screening device can be flexibly moved to the work point in the mining area. After arriving at the work site, the hydraulic cylinder 304 retracts, so that the wheel 303 rises. At the same time, the steel frame 1 lands on the ground and is supported by the steel frame 1. The frame 2 is vibrated by the vibrating motor 7. The ore is fed into the feed hopper 10 by the lifting equipment at the work site, so that the ore is vibrated and screened on the screen plate 9. Small pieces of ore are screened onto the guide plate 11, and large pieces of ore are discharged from the screen plate 9, thus completing the vibrating screening of the ore.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
