Description

Technical Field

[0001] The utility model relates to a jaw crusher, in particular to a jaw crusher for stone production. Background Art

[0002] The jaw crusher is the most commonly used crushing equipment in ore dressing production. It is a crushing machine that uses the extrusion and bending actions of two jaw plates to coarsely or medium-crush various hardness materials. Its crushing mechanism consists of a fixed jaw plate and a movable jaw plate. When the two jaw plates approach, the material is crushed. When the two jaw plates separate, the material blocks smaller than the discharge opening are discharged from the bottom. Its crushing action is intermittent. During the use of the jaw crusher, especially when crushing large stones, the stones are prone to jump outwards, and the dust on the stones will fly to the outside during the jumping process of the stones, deteriorating the working environment.

[0003] For example, a patent with the application number 202221883764.6 discloses a safe and explosion-proof jaw crusher. In this safe and explosion-proof jaw crusher, by starting the first water pump and the atomizing nozzle, part of the water in the water tank is discharged through the second arc-shaped pipe, and the discharged water falls into the crushing cavity to wet the stones, thereby reducing the possibility of generating sparks due to the friction between the stones. At the same time, by starting the atomizing nozzle, the water in the first arc-shaped pipe is sprayed in the form of water mist, so that the water mist contacts the dust, accelerating the discharging speed of the dust, and thus achieving the effect of avoiding dust explosion. However, during the process of processing stones by a general jaw crusher, a large amount of sediment is contained in the stones. Spraying water in the form of water mist easily causes sediment to adhere to the stones, affecting the quality of the stones. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a jaw crusher for stone production. It can wash the stones entering the crushing box body, avoid a large amount of sediment carried by the stones from affecting the quality of the stones, and can reduce dust.

[0005] The technical solution of the utility model: A jaw crusher for stone production, including a crushing box body. A fixed jaw plate is arranged inside the crushing box body. A movable jaw plate that can move relative to the fixed jaw plate is arranged on one side of the fixed jaw plate. A driving mechanism for driving the movement of the movable jaw plate is arranged on one side of the movable jaw plate. It is characterized in that: an inlet feeding mechanism is arranged on the upper side of the crushing box body. The inlet feeding mechanism includes two parallel and vertically arranged side plates. A mesh belt conveyor is arranged in the middle between the two side plates. A guide plate for collecting muddy water is arranged under the mesh belt conveyor and installed between the side plates. A muddy water collection box is arranged under the guide plate. A flushing pipe is arranged on the upper side of the mesh belt conveyor. A stone collection box corresponding to the fixed jaw plate and the movable jaw plate is arranged on the lower side of the crushing box body.

[0006] In the aforementioned jaw crusher for stone production, the muddy water collection box includes a collection box body. On both sides in the collection box body, there are multiple groups of sieve plates symmetrically arranged with respect to the parallel line in the middle of the two side plates.

Detailed Embodiment

[0013] The following further illustrates the present utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0014] Embodiment. A jaw crusher for stone production, the structure is as Figure 1-2As shown in the figure, it includes a crushing box body 1. Inside the crushing box body 1, there is a fixed jaw plate 2. On one side of the fixed jaw plate 2, there is a movable jaw plate 3 that can move relative to the fixed jaw plate 2. On one side of the movable jaw plate 3, there is a driving mechanism for driving the movement of the movable jaw plate 3. It is characterized in that: on the upper side of the crushing box body 1, there is a feeding mechanism. The feeding mechanism includes two parallel and vertically arranged side plates 9. In the middle between the two side plates 9, there is a mesh belt conveyor 4. Below the mesh belt conveyor 4, there is a guide plate 8 installed between the side plates 9 and used for collecting muddy water. Below the guide plate 8, there is a muddy water collection box 5. Above the mesh belt conveyor 4, there is a shower pipe 6; below the crushing box body 1, there is a stone collection box 7 corresponding to the fixed jaw plate 2 and the movable jaw plate 3.

[0015] The muddy water collection box 5 includes a collection box body 10. On both sides in the collection box body 10, there are multiple groups of sieve plates 11 symmetrically arranged with respect to the middle parallel line of the two side plates 9. The lower ends of the sieve plates 11 are parallel to the bottom surface of the collection box body 10. On the bottom surface of the collection box body 10, there are card seats 17 for fixing the sieve plates 11. At the upper ends of the sieve plates 11, there are guiding plates 12 for fixing the sieve plates. The guiding plates 12 are inclined and arranged on the side walls of the collection box body 10. Below the guiding plates 12, there are card slots 16 cooperating with the sieve plates 11.

[0016] The lower ends of the sieve plates 11 are provided with uniformly distributed sieve holes 13, and the upper parts of the sieve plates 11 are provided with water discharge grooves 14.

[0017] The side wall of the collection box body 10 is provided with a connecting pipe 15 for connecting the shower pipe 6.

[0018] Principle of the utility model: The crushing box body 1, fixed jaw plate 2, moving jaw plate 3 and the drive mechanism for driving the movement of the moving jaw plate 3 in this application are all prior arts, so no detailed description will be given. The drive mechanism is the same as that of the existing jaw crusher. It drives the flywheel to drive the movement of the moving jaw plate 3 through the cooperation of the motor and the conveyor belt, and is coordinated by the thrust plate. Before the stone material enters the crushing box body 1 in this application, it will be conveyed and cleaned through the feeding mechanism. The sediment on the stone material will first fall from the pores of the metal mesh belt of the mesh belt conveyor 4 under the action of gravity and directly fall into the muddy water collection box 5. However, fly ash will be generated when the sand and gravel fall, causing the deterioration of the working environment. Therefore, a flushing pipe 6 is provided on the mesh belt conveyor 4 in this application, which can not only flush the stone material to wash away the sediment adhering to the surface of the stone material, but also avoid the generation of fly ash when the stone material falls. The setting of the guide plate 8 can prevent the muddy water from falling on the crushing box body 1. A guide plate 12 is provided in the muddy water collection box 5, and the muddy water will fall along the guide plate 12 between the two middlemost screen plates 11 of the collection box screen plate 11. The muddy water will be screened through the screen holes 13. The sediment will be stored between the screen plates 11, and the water will flow to the outer screen plates for multiple screenings. Finally, it can be conveyed to the flushing pipe 6 through the connecting pipe 15 for reuse. When the sediment accumulates too much, it will affect the passing rate of water. At this time, the water level between the two middle screen plates will rise, thereby increasing the water pressure at the lower screen holes 13 and improving the flow rate. When the flow rate between the screen plates cannot keep up with the falling rate of the muddy water, the muddy water will flow from the drain trough 14 to between the two outer groups of screen plates 11, and the sediment will be filtered by the outer screen plates 11. When a large amount of sediment accumulates on the inner sides of multiple groups of screen plates 11, the sediment in the muddy water collection box 5 can be cleaned. By setting multiple groups of screen plates in this application, the water sent to the flushing pipe 6 can be cleaner. The screen plates are inclined, so the contact area with the muddy water is larger at the same height, and the screening effect is better.
