Description

Technical Field

[0001] The utility model belongs to the technical field of screening equipment, and particularly relates to a horizontal feeding type crawler mobile screening station. Background Art

[0002] Traditional fixed screening stations need to be set on the side slope or the ground surface of the mine field, and platforms are built by driving piles. This installation method is complex, with low efficiency, and the cost of transfer transportation is high. Although the existing mobile screening stations solve the problem of transportation and transfer, they usually need to be equipped with additional power sources such as commercial power to provide power for the operation of the motor to work properly. This makes them not very suitable for unpowered areas such as remote suburbs and wasteland. At the same time, the existing screening stations usually only have simple small-capacity hoppers, and additional equipment such as excavators are required to continuously supply materials. The material supply is unstable, resulting in low overall screening efficiency of the screening station, and the screening device of the screening station can only perform one screening, with low product quality and output. In addition, the vibrating screens of the existing mobile screening stations are usually equipped with iron woven screen meshes. Such screen meshes have poor wear resistance and are prone to rust and corrosion. Once a certain place is rusted and worn through, the entire screen mesh needs to be replaced, resulting in frequent replacement of the screen mesh. And generally, the space for replacing the screen mesh of the vibrating screen is small, the time for replacing the screen mesh is long, and the difficulty is large, affecting the production efficiency of the vibrating screen.

The support legs 23 are vertically arranged and are connected to the left side of the bottom surface of the hopper through an oil cylinder. The support legs 23 are driven by the oil cylinder to expand and contract, so as to adapt to different site requirements. At the same time, the support stability is enhanced through the oil cylinder, so that the whole machine remains stable during operation and prevents vibration or shaking during feeding. Materials enter the hopper of the feeding assembly 2 and are sent into the feeding-up assembly 3 through the feeding conveyor belt 22.

[0039] As Figure 3 shown in the figure, the feeding-up assembly 3 includes a feeding-up conveyor belt 31. The feeding-up conveyor belt 31 is arranged on the vehicle frame 1. The top surface of its left side is arranged below the right end of the feeding conveyor belt 22, and its right end is inclined upward. Materials are sent out from the feeding conveyor belt 22 of the feeding assembly 2, fall onto the feeding-up conveyor belt 31, and are then transported to the screening assembly 4 through the feeding-up conveyor belt 31.

[0040] As Figures 4-5 shown in the figure, the screening assembly 4 includes a screening frame 41, a screening component 42, a material guiding component 43, and a vibrator 44. The screening frame 41 is arranged on the vehicle frame 1 and is located below the right side of the feeding-up conveyor belt 31. The top and bottom surfaces of the screening frame 41 are open, and its right end is inclined upward. The vibrator 44 is arranged on the front side wall of the screening frame 41. The screening component 42 is arranged inside the screening frame 41, and the screening component 42 is provided with three layers, namely upper, middle, and lower layers, at intervals from top to bottom. Materials enter the screening frame 41 from the feeding-up conveyor belt 31 and fall into the screening component 42, and are vibrationally screened through the vibrator 44. The three-layer screening component 42 screens the materials to obtain materials with different particle sizes. The material guiding component 43 includes a first material guiding hopper 431 and a second material guiding hopper 432. The first material guiding hopper 431 and the second material guiding hopper 432 are respectively vertically arranged at intervals at the left end of the screening frame 41, and the first material guiding hopper 431 corresponds to the upper and middle screening components 42, and the second material guiding hopper 432 corresponds to the lower screening component 42.

Materials that can pass through the lower screening component 42 fall downward onto the finished product conveyor belt 51 of the discharging assembly 5.

[0041] As Figures 5-6As shown in the figure, the screening assembly 42 includes a fixing plate 421 and a screen 422. The fixing plate 421 is arranged inside the screening frame 41 and there are multiple ones arranged at intervals in the front and rear direction. The left and right ends thereof are vertically and fixedly connected to the front and rear side walls inside the screening frame 41. There are multiple screens 422, which are respectively laid on multiple fixing plates 421. Semi-circular mounting holes are opened at the front and rear ends of the fixing plate 421. The mounting holes of two adjacent screens 422 are combined into a circular mounting hole. The fixing plate 421 is provided with fixing holes at positions corresponding to the circular mounting holes. By inserting a dowel pin 423 into the circular mounting hole formed by combining two screens 422 and the fixing hole of the fixing plate 421, the screen 422 and the fixing plate 421 are connected by expansion mounting. The screen 422 apertures of the upper-layer screening assembly 42 and the middle-layer screening assembly 42 are the same, and the screen 422 aperture of the lower-layer screening assembly 42 is smaller than the screen 422 apertures of the upper-layer screening assembly 42 and the middle-layer screening assembly 42, so as to obtain three kinds of materials with different particle sizes.

[0042] The screen 422 and the dowel pin 423 are made of polyurethane non-metallic wear-resistant material, with a long service life, a lower replacement frequency of the screen 422, and when the screen 422 needs to be replaced, the dowel pin 423 can be directly burned to prevent the traditional fastening screws from rusting and making it difficult to replace the screen 422.

Through the folding mechanism 6, the feeding conveyor belt 31, the first side conveyor belt 52, and the second side conveyor belt 53 can be folded. The folding of the feeding conveyor belt 31 facilitates the folding, transfer, and deployment of this conveyor belt during the assembly of the whole machine for work. The folding of the first side conveyor belt 52 and the second side conveyor belt 53 is applicable to different working states. When the first side conveyor belt 52 and the second side conveyor belt 53 are folded, the volume of the whole machine can be reduced, which is convenient for the mobile transportation of the whole machine and is deployed during the screening work.

[0046] As Figures 1-9 shown in the figure, spraying mechanisms 7 are provided on the feeding conveyor belt 31, the first side conveyor belt 52, the second side conveyor belt 53, and the finished product conveyor belt 51.

[0047] A support framework is also provided on the vehicle frame 1; the screening assembly 4 is connected to the vehicle frame 1 through the support framework; a maintenance platform is also provided on the support framework for maintaining the screening assembly 4.

[0048] A control system is also provided on the vehicle frame 1; the control system includes a controller and an electric control box, which are used to control the walking of the crawler 11 and the start and stop of each assembly.

[0049] The working mode of the present utility model is as follows:

[0050] Materials first enter the feeding hopper 21 of the feeding assembly 2 and are conveyed to the feeding conveyor belt 31 of the feeding assembly 3 through the feeding conveyor belt 22. The feeding conveyor belt 31 sends the materials into the screening framework 41 of the screening assembly 4, and the materials are screened by the vibrating machine 44 and the three-layer screening assembly 42. During the screening process, the materials that cannot pass through the meshes 422 of the upper-layer screening assembly 42 and the middle-layer screening assembly 42 are sent out through the first guiding hopper 431 and fall onto the first side conveyor belt 52 of the discharging assembly 5 and are conveyed through the first side conveyor belt 52; the materials that cannot pass through the meshes 422 of the lower-layer screening assembly 42 are sent out from the second guiding hopper 432 and fall onto the second side conveyor belt 53 of the discharging assembly 5 and are sent out through the second side conveyor belt 53; the materials that can pass through the lower-layer screening assembly 42 fall downward onto the finished product conveyor belt 51 of the discharging assembly 5 and are sent out as finished products by the finished product conveyor belt 51.
