Description

Technical Field

[0001] The utility model relates to the technical field of jaw crushers, and relates to a discharging structure of a jaw crusher. Background Art

[0002] The jaw crusher is an efficient crushing device. After mining, many ores are obtained, and the jaw crusher is required to perform coarse crushing on these ores. After the jaw crusher completes the crushing, it needs to be conveyed to the conveyor belt through the discharging structure and then conveyed to the next process. There is a certain distance between the discharging structure of the jaw crusher and the conveyor belt to allow the discharging structure to divert the crushed stones to the conveyor belt and then send them away. However, the existing discharging structure of the jaw crusher is difficult to buffer the falling crushed stones. Under the action of gravity and impact force, the crushed stones are likely to damage the conveyor belt, and a large amount of dust is contained in the crushed stones. When these dusts directly diffuse into the environment, it will cause dust pollution. Summary of the Utility Model

[0003] In view of the above technical problems existing in the prior art, a discharging structure of a jaw crusher is provided, which solves the problems that the existing discharging structure of the jaw crusher is difficult to buffer the falling crushed stones, the crushed stones are likely to damage the conveyor belt under the action of gravity and impact force, and a large amount of dust is contained in the crushed stones, and when these dusts directly diffuse into the environment, it will cause dust pollution.

[0004] The purpose and effect of the utility model are achieved by the following specific technical means:

[0006] A rotating ring is rotatably connected to the discharging port of the crusher main body, the rotating ring is detachably connected to a discharging pipe, and an elastic dust cover is detachably connected to the lower end of the discharging pipe;

[0007] The discharging pipe includes two bent pipes. Rubber soft pads are fixed on the upper inner walls of the two bent pipes, and elastic mesh plates are fixed on the lower inner walls of the two bent pipes. The two bent pipes are spliced diagonally. The upper end of the upper bent pipe is detachably connected to the rotating ring, and the lower end of the lower bent pipe is detachably connected to the elastic dust cover.

[0008] Optionally, flange plates are fixed at both ends of the bent pipe, and the rotating ring is connected to the bent pipe, the bent pipes are connected to each other, and the bent pipe is connected to the elastic dust cover through the flange plates.

[0009] Optionally, a number of uniformly distributed anti-slip protrusions are integrally formed on the rubber soft pad.

[0010] Optionally, the elastic dust cover includes an elastic mesh cover and a dust-proof cloth. The elastic mesh cover is connected to the lower end of the lower elbow through a flange, and the dust-proof cloth is wrapped outside the elastic mesh cover.

[0011] Optionally, the crusher main body is provided with an annular chute surrounding the periphery of the discharge port. A support member is detachably connected at the connection of the two elbows, and the upper end of the support member is slidably connected in the annular chute.

[0012] Optionally, the support member includes a mounting plate and a slider. There are two mounting plates, which are respectively detachably connected to the upper surfaces of the two elbows, and the upper ends of the mounting plates are both detachably connected to the bottom of the slider.

[0013] Optionally, a conveyor belt for transporting crushed ore is provided below the elastic dust cover.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the discharge structure of this jaw crusher, the two elbows are spliced diagonally, so that the discharge pipe forms a wavy elbow. The purpose is to slow down the falling speed of the crushed stones in the discharge pipe, thereby reducing the impact force of the crushed stones on the conveyor belt and playing a good protective role for the conveyor belt. Among them, the elastic mesh plate and the rubber soft pad are both elastic, which can play a buffering role for the crushed stones falling into the elbow, and can well protect the discharge pipe.

Specific embodiments

[0023] Please refer to Figures 1-5 , and make further explanations for the embodiments of the present utility model;

[0024] A discharge structure of a jaw crusher includes a crusher main body 1, and a discharge port 11 is opened at the bottom of the crusher main body 1;

[0025] As Figure 1 shown, a rotating ring 13 is rotatably connected to the discharge port 11 of the crusher main body 1. The rotating ring 13 is detachably connected to a discharge pipe 2, and the lower end of the discharge pipe 2 is detachably connected to an elastic dust-proof cover 3. The lower end face of the elastic dust-proof cover 3 is much larger than the upper end face. On the one hand, it is convenient for discharging materials, and on the other hand, it expands the dust control surface. A conveyor belt 4 for transporting crushed ore is provided below the elastic dust-proof cover 3. The lower end of the elastic dust-proof cover 3 is closely close to the conveyor belt 4. The specific distance between the elastic dust-proof cover 3 and the conveyor belt 4 needs to be adjusted according to the size of the crushed stones. After the crusher main body 1 crushes large ore into crushed stones, the crushed stones enter the discharge pipe 2 through the discharge port 11 and finally flow onto the conveyor belt 4. The crushed stones are sent away through the conveyor belt 4. The setting of the elastic dust-proof cover 3 can effectively prevent a large amount of dust from being lifted out from the gap between the discharge pipe 2 and the conveyor belt 4 when the crushed stones fall on the conveyor belt 4. Since the elastic dust-proof cover 3 has elasticity, the crushed stones will squeeze the lower end of the elastic dust-proof cover 3 during the transportation of the conveyor belt 4, and the elastic dust-proof cover 3 will undergo elastic deformation, which does not affect the normal transportation of the crushed stones.

[0026] As Figures 2-4As shown in the figure, the discharge pipe 2 includes two bent pipes 21. Rubber soft pads 23 are fixed on the upper inner walls of the bent pipes 21 (the inner walls on the side with a smaller curvature of the bent pipes 21), and elastic mesh plates 22 are fixed on the lower inner walls of the bent pipes 21 (the inner walls on the side with a larger curvature of the bent pipes 21). The two bent pipes 21 are spliced diagonally, making the discharge pipe 2 form a wavy bent pipe. The purpose is to slow down the falling speed of the crushed stones in the discharge pipe 2, thereby reducing the impact force of the crushed stones on the conveyor belt 4 and playing a good protective role for the conveyor belt 4. Among them, both the elastic mesh plate 22 and the rubber soft pad 23 are elastic and can buffer the crushed stones falling into the bent pipe 21. Moreover, the surface of the elastic mesh plate 22 is rough, and a number of uniformly distributed anti-slip bumps 231 are integrally formed on the rubber soft pad 23, which can further slow down the falling speed of the crushed stones in the discharge pipe 2. The upper end of the upper bent pipe 21 is detachably connected to the rotating ring 13, and the lower end of the lower bent pipe 21 is detachably connected to the elastic dust cover 3. The specific detachable connection method is that flange plates 24 are fixed at both ends of the bent pipe 21, and the rotating ring 13 and the bent pipe 21, between the bent pipes 21, and between the bent pipe 21 and the elastic dust cover 3 are all connected through the flange plates 24, which is convenient for workers to disassemble and replace the elastic dust cover 3 and the two bent pipes 21.

[0027] As Figure 1 and 2 shown, the elastic dust cover 3 specifically includes an elastic mesh cover 31 and a dust-proof cloth 32. The elastic mesh cover 31 is connected to the lower end of the lower bent pipe 21 through a flange plate 24, and the dust-proof cloth 32 is wrapped outside the elastic mesh cover 31. The elastic mesh cover 31 is made of a spring mesh plate, and the spring mesh plate is elastic. On the one hand, it is beneficial for the elastic dust cover 3 to reduce the distance between the bent pipe 21 and the conveyor belt 4 to a greater extent. On the other hand, when the conveyor belt 4 conveys the crushed stones, the crushed stones will squeeze the spring mesh plate and cause it to undergo elastic deformation, which does not affect the normal conveyance of the crushed stones. The dust-proof cloth 32 can prevent the dust in the elastic mesh cover 31 from spreading into the environment, thereby greatly reducing dust pollution.

[0028] In order to enhance the stability of the discharge pipe 2 on the crusher main body 1 and reduce the load of the crushed stones falling on the discharge pipe 2, an annular chute 12 is opened on the crusher main body 1 around the periphery of the discharge port 11. A support member 5 is detachably connected at the joint of the two bent pipes 21, and the upper end of the support member 5 is slidably connected in the annular chute 12. The support member 5 specifically includes a mounting plate 51 and a slider 52. There are two mounting plates 51, which are respectively detachably connected to the upper surfaces of the two bent pipes 21, and the upper ends of the mounting plates 51 are both detachably connected to the bottom of the slider 52.

[0029] In this embodiment, during use, the crusher main body 1 crushes large ore into gravel, which then enters the discharge pipe 2 through the discharge port 11. First, it enters the upper elbow pipe 21. Since the inner wall of the side with a larger curvature of the upper elbow pipe 21 will be impacted by the gravity direction of the gravel, and the inner wall of the side with a larger curvature of the lower elbow pipe 21 will be impacted laterally by the falling stones, elastic net plates 22 with relatively large elasticity are specifically arranged on the inner walls of the sides with larger curvatures of the two elbow pipes 21, which can effectively buffer the impact force of the gravel. The inner walls of the sides with smaller curvatures of the two elbow pipes 21 are impacted by the gravel with relatively small force, so rubber soft pads 23 with relatively small elasticity are selected. By using the elastic net plates 22 and the rubber soft pads 23, the discharge pipe 2 can be effectively protected. In addition, since the two elbow pipes 21 are spliced diagonally, the discharge pipe 2 forms a wavy elbow pipe, which can slow down the falling speed of the gravel in the discharge pipe 2, thereby reducing the impact force on the conveyor belt 4 and playing a very good protective role for the conveyor belt 4. Moreover, the surface of the elastic net plate 22 is rough, and a number of anti-slip bumps 231 are integrally formed on the rubber soft pad 23 and are evenly distributed, which can further slow down the falling speed of the gravel in the discharge pipe 2;

[0030] When the gravel falls in the discharge pipe 2, the discharge pipe 2 will be continuously and slightly rotated under the influence of the impact force, thereby driving the rotating ring 13 and the elastic dust-proof cover 3 to rotate together. Thereby, the impact force of the gravel can be consumed, which can not only extend the service life of the discharge pipe 2, but also change the position where the gravel falls on the conveyor belt 4, and can effectively prevent the accumulation of gravel in the elastic dust-proof cover 3. It should be noted that no matter how many degrees the discharge pipe 2 rotates, the outlet of the discharge pipe 2 is aligned with the conveyor belt 4, that is, the rotation range of the discharge pipe 2 is on the conveyor belt 4;

[0031] The gravel will pass through the elastic dust-proof cover 3 and fall onto the conveyor belt 4. Since the elastic dust-proof cover 3 is close to the conveyor belt 4, the setting of the elastic dust-proof cover 3 can greatly reduce the dust carried in the gravel from spreading into the air from the discharge. Since the elastic dust-proof cover 3 has elasticity, when the gravel is conveyed by the conveyor belt 4, the lower end of the elastic dust-proof cover 3 will be squeezed, and the elastic dust-proof cover 3 will undergo elastic deformation, which does not affect the normal conveyance of the gravel.
