Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a jaw crusher tracked machine. Background Technology

[0002] Jaw crushers are widely used in primary crushing of stone materials due to their robust structure and large crushing ratio in projects such as building demolition, mining, and roadbed treatment. Traditional mobile jaw crushers typically integrate the vibrating feeder and crusher directly into a tracked chassis, giving them a certain degree of mobility.

[0003] In the field of stone crushing, raw materials (such as construction waste or surface minerals) often contain a large amount of soil and debris. Existing equipment directly feeds these materials into the crushing chamber, resulting in: sticky soil clogging the jaw plate teeth, reducing crushing efficiency; and excessive soil content in the crushed stone (>8%), failing to meet the requirements for high-quality aggregates. Furthermore, the mixing of fine soil particles with crushed stone during crushing generates high-concentration dust (PM10 concentration exceeding 300μg / m³) during transfer, severely polluting the working environment; simultaneously, residual soil accumulates inside the equipment, requiring frequent shutdowns for cleaning (averaging 2-3 hours per shift), reducing equipment utilization. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a jaw crusher tracked machine. This design effectively solves the problems of existing jaw crushers lacking a soil separation device before crushing, which leads to soil and rock mixing, resulting in reduced crushing efficiency, and heavy dust pollution during the crushing process.

[0006] The screening assembly includes a vibrating frame located inside the feed inlet. A third conveyor belt is rotatably connected to the vibrating frame. A screen plate is provided on the front side of the third conveyor belt. The screen plate is fixedly connected to the vibrating frame. The screen plate is placed at an angle on the vibrating frame and is located at the upper end of the opening of the first hopper.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0021] Please see the appendix Figure 1-5 This embodiment describes a jaw crusher tracked machine, comprising a frame 1, a feed inlet 2 on the frame 1, a screening assembly 3 at the feed inlet 2, a first hopper 4 connected below the screening assembly 3, the first hopper 4 being fixedly connected to the frame 1, a folding material rack 5 connected to the side of the frame 1, a first conveyor belt 6 on the folding material rack 5, one side of the first conveyor belt 6 being located below the discharge port of the first hopper 4 along the material forward direction, a jaw crusher 7 being located in front of the screening assembly, a supporting material rack 8 being located on the side of the jaw crusher 7, a second conveyor belt 9 on the supporting material rack 8, one end of the first conveyor belt 6 being located below the discharge port of the jaw crusher 7.

[0022] Frame 1 serves as the supporting component for the entire equipment. The power system and control system are housed within Frame 1. Frame 1 has a ship-shaped structure, constructed entirely of Q355 steel plates. The upper left side of Frame 1 houses the feed inlet 2, where materials are transported by a loader or excavator. A screening assembly 3 is installed at the feed inlet 2, filtering out soil mixed in with the material. The screening assembly 3 performs both screening and transport functions at the feed inlet 2. The soil is screened at the feed inlet 2 and falls by gravity onto the first conveyor belt 6. The first conveyor belt 6 transports the soil towards the rear of Frame 1. The screening assembly then transports large stones from the upper side forward to the jaw crusher. At the top opening of 7, the jaw crusher 7 is the existing technology. Its structure adopts a deep cavity jaw crusher structure, which includes a fixed jaw plate, a movable jaw plate and an eccentric shaft drive mechanism. The crushing chamber angle is 22°, the maximum feed particle size is 480mm, and the discharge port adjustment range is 50-150mm (hydraulic adjustment). The equipment is rigidly connected to the frame 1 (1) by high-strength bolts. The bottom is equipped with a shock-absorbing base to absorb impact loads. The side of the jaw crusher 7 is a support frame 8. The support frame 8 has a second conveyor belt 9 for transporting crushed stones. The second conveyor belt 9 and the support frame 8 face the right side of the frame 1, which can reduce the horizontal width of the frame 1 and facilitate the movement of the device.

[0023] Specifically, the material enters the feed inlet 2 through the transfer equipment. The material entering the feed inlet 2 is piled on the screening assembly 3. The screening assembly 3 screens and transports the material. Smaller soil and stone chips fall through the screening assembly into the first hopper 4, and then fall onto the first conveyor belt 6 under the action of gravity. The first conveyor belt 6 is then transferred to the rear side of the frame 1. Larger stones cannot pass through the screening assembly and enter the jaw crusher 7 under the action of its forward transport. The jaw crusher 7 crushes the material. The crushed material falls onto the second conveyor belt 9 under the action of gravity and is then transferred to the right side of the frame 1.

[0024] The screening assembly 3 includes a vibrating frame 301 located inside the feed inlet 2. The vibrating frame 301 is rotatably connected to a third conveyor belt 302. A screen plate 303 is provided on the front side of the third conveyor belt 302. The screen plate 303 is fixedly connected to the vibrating frame 301. The screen plate 303 is placed at an angle on the vibrating frame 301 and is located at the upper end of the opening of the first hopper 4.

[0025] The vibrating frame 301 within the screening assembly 3 is suspended at the feed inlet 2 via spring shock absorbers. The vibrating frame 301 is equipped with a vibrating motor, generating high-frequency linear vibration (amplitude 3-5mm, frequency 15-25Hz). The third conveyor belt 302 is rotatably connected to the bottom of the vibrating frame 301 via a bearing seat. It is an impact-resistant corrugated sidewall belt with a width of 800mm and an inclination angle of 10°, used to receive the initial material and convey it forward. The screen plate 303 is welded and fixed to the front of the vibrating frame 301, with an inclination angle of 20° (preferably 15°-25°), and the screen aperture size is adjustable (typically a 30mm × 50mm square hole). Its bottom edge is suspended 50mm directly above the opening of the first hopper 4, allowing the screened material to fall directly into the first hopper 4.

[0026] The folding rack 5 is used for folding and storing the first conveyor belt 6. When not in use, the folding rack 5 folds the first conveyor belt 6 to the side of the frame 1. This allows the first conveyor belt 6 to be placed close to the frame 1, which helps to reduce the overall lateral width of the device and facilitates movement. The first support 501 is a steel truss, which is not hinged to the frame 1 by a pin. The first support 501 and the frame 1 can rotate vertically. One end of the first support 501 is located below the first hopper 4. The second support 503 is hinged to the outside of the first support 501. The second support 503 can rotate left and right relative to the first support 501. The first telescopic rod 502 and the second telescopic rod 504 are both connected to hydraulic cylinders. They have the same driving method and have a self-locking function after extension and retraction to ensure the stability of subsequent support.

[0027] Specifically, before use, the second support 503 is folded to the side of the frame 1. During use, the first support 501 is rotated counterclockwise by the first telescopic rod 502. After the first support 501 rotates counterclockwise, the right side of the first support 501 moves to the bottom of the first hopper 4. At the same time, the second telescopic rod 504 drives the second support 503 to rotate to the left relative to the first support 501 until the second support 503 rotates to a state where it is collinear with the first support 501. At this time, the first conveyor belt 6 is just taut on the first support 501 and the second support 503. At this time, the first conveyor belt 6 plays the role of transporting soil under the first hopper 4.

[0028] The connecting block 10 is welded to the bottom of the support frame 8 and connected to the traction rod 11 through a universal joint. The other end of the traction rod 11 is hinged to the frame 1 to form a torsional stable structure. The support frame 8 is placed obliquely upward, which can raise the discharge height of the right end of the second conveyor belt 9, making it easier to collect the stones later. The iron separator 12 is installed parallel above the second conveyor belt 9. Side plates are provided on the support frames 8 on both sides of the second conveyor belt 9. The side plates shield the stones and prevent them from falling from the side. At the same time, the second conveyor belt 9 has a belt conveyor, a dust suppression device, and head and tail cleaners. The iron separator 12 is used to identify stones with high iron content to make full use of resources.

[0029] The iron separator 12 is suspended above the support frame 8: the first connecting rod 13 and the second connecting rod 14 are respectively hinged to the two ends of the iron separator 12 and the frame 1, forming a parallelogram mechanism. The third telescopic rod 15 is hydraulically telescopic, with one end hinged to the middle of the second connecting rod 14 and the other end hinged to the frame 1, driving the iron separator 12 to be adjusted within a range of 300-600mm from the second conveyor belt 9 and the belt surface.

[0030] There are two sets of track wheels 16, each connected to a power mechanism. The track's ground contact length on one side is 3.2m, its width is 500mm, and its maximum climbing ability is 25°. There are three sets of folding guard plates 17, two located on the front and rear sides of the discharge port, and the other on the left side. The folding guard plates 17 are hinged to the side wall of the feed inlet 2. The fourth telescopic rod 18 is also hydraulically driven, with its two ends hinged to the back of the guard plate and the frame 1 respectively, allowing for adjustment of the guard plate from 0° (vertical protection) to 180° (fitted with the frame 1). The material falls through the feed inlet 2 onto the third conveyor belt 302 on the vibrating frame 301, and is then conveyed forward to the screen plate 303.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
