[0002] With the development of the construction industry, more and more advanced technologies have been researched and developed, and fluidized solidified loess is one of the construction materials. When crushing the fluidized solidified loess, the raw materials need to be crushed into the required size, then mixed with other materials and water, stirred into a plastic mud, and then injected into the place where it is needed and waited for solidification. When crushing the material, large-scale crushing equipment such as jaw crushers and impact crushers are generally used for crushing, and then the appropriate particle size is screened through a vibrating screen for use. However, the existing crushing device needs to move the crushed material to the screening frame for screening before it can be used, which is very inconvenient and easily causes the material to spill, causing environmental pollution and waste of materials.

While the specifications of the screen plate can be changed, the crushed material can be screened, so that the crushed material can be directly screened without transportation, thereby reducing the loss incurred during transportation.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the fluidized solidified loess production and grading crushing device based on high-frequency vibration screening has:

[0018] 1. By putting materials into the frame, the put materials enter between the movable jaw pressure plate and the fixed jaw pressure plate for crushing.

[0020] 3. As the driving motor rotates, the rotating pulley will be driven to rotate, and the first belt will drive the driving pulley to reduce the speed, so that the movable pressure plate will reduce the speed, and the impact and loss caused by the excessive rotation of the movable pressure plate and the eccentric shaft will be reduced.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6The utility model provides a technical solution: a fluidized solidified loess production and grading crushing device based on high-frequency vibration screening, comprising a frame 1, a driving motor 2 is fixedly installed on the side surface of one end of the frame 1, and the driving motor 2 is located on the side surface of the frame 1, an eccentric rotating shaft 6 is penetrated and installed on the side surface of one end of the frame 1, and a movable pressing plate 7 is rotatably installed on the outer surface of the eccentric rotating shaft 6, and a movable jaw pressing plate 8 is fixedly installed on the side surface of the movable pressing plate 7, a fixed jaw pressing plate 9 is fixedly installed on the side surface of the frame 1, and the fixed jaw pressing plate 9 is located on the inner side of the frame 1, and the fixed jaw pressing plate 9 is opposite to the movable jaw pressing plate 8, and a rotating mechanism is arranged inside the frame 1, and the crushed material is screened by the rotating mechanism to remove the loss generated when transporting the material.

[0030] The material to be crushed is put into the frame 1, so that the material falls between the movable jaw pressure plate 8 and the fixed jaw pressure plate 9. Then, the driving motor 2 is started to drive the eccentric shaft 6 to rotate, so that the movable pressure plate 7 can swing up and down with the rotation of the eccentric shaft 6, so that the material is crushed by the extrusion of the movable jaw pressure plate 8 and the fixed jaw pressure plate 9.

[0031] The rotating mechanism includes: a screening frame 16, which is fixedly installed on the inner side of the frame body 1, and an elastic rubber pad is arranged between the frame body 1 and the screening frame 16, and the screening frame 16 is designed to be inclined, a screen plate 17 is slidably installed inside the screening frame 16, and the screen plate 17 is snap-fitted to the screening frame 16, a screw is threadedly installed on the outer surface of the screening frame 16, and the screening frame 16 is snap-fitted to the screw, a vibration barrel 15 is fixedly installed on the side surface of one end of the screening frame 16, and an eccentric block is arranged inside the vibration barrel 15.

[0032] The crushed material will fall on the outer surface of the sieve plate 17, and then through the vibration of the screening frame 16, the material smaller than the sieve holes of the sieve plate 17 will fall directly and fall on the outer surface of the frame 1 to be transported to the next process, while the material larger than the sieve holes of the sieve plate 17 will be directly discharged from the frame 1 along the inclined surface of the screening frame 16. At the same time, the sieve plate 17 can be removed from the screening frame 16 for replacement by unscrewing the screws to obtain the required material coarseness, and the unqualified materials from the frame 1 can be directly put back between the movable jaw pressure plate 8 and the fixed jaw pressure plate 9 for re-crushing, while the loss generated during the movement from crushing to the screening machine can be reduced.

[0033] A connecting plate 10 is rotatably mounted on the side surface of the movable pressure plate 7, an adjusting seat 11 is slidably mounted on the inner surface of the frame 1, and the outer surface of the adjusting seat 11 is rotatably connected to the connecting plate 10, and the adjusting seat 11 passes through the outer surface of the frame 1, and a spring is arranged between the frame 1 and the adjusting seat 11.

[0034] By adjusting the position of the adjusting seat 11 in the frame 1, the movable pressure plate 7 can be pulled to move through the connecting plate 10, so that the distance between the movable jaw pressure plate 8 and the fixed jaw pressure plate 9 can be adjusted, and the required size can be roughly achieved when crushing materials. At the same time, the spring can be used to release the force of the movable pressure plate 7 when encountering hard materials that cannot be crushed.

[0035] A transmission mechanism is arranged between the eccentric rotating shaft 6 and the driving motor 2, and the rotation speed of the eccentric rotating shaft 6 is reduced by the transmission mechanism so that the movable pressure plate 7 does not rotate at excessive speed. The transmission mechanism includes: a driving pulley 4, which is fixedly mounted on one end of the eccentric rotating shaft 6 close to the driving motor 2, and a rotating pulley 3 is fixedly mounted on the output end of the driving motor 2, and a first belt 5 is arranged between the rotating pulley 3 and the driving pulley 4, and the diameter of the rotating pulley 3 is smaller than the diameter of the driving pulley 4.

[0036] The rotating pulley 3 is driven to rotate by the rotation of the driving motor 2, so that the first belt 5 drives the driving pulley 4 to rotate, and the rotation speed of the eccentric shaft 6 is reduced by the diameter difference between the rotating pulley 3 and the driving pulley 4, thereby reducing the impact force and fatigue wear generated by the movable pressure plate 7 when moving and extruding, thereby improving the service life of the movable pressure plate 7 and the eccentric shaft 6.

[0037] A secondary pulley 12 is fixedly installed on the end of the eccentric shaft 6 away from the driving pulley 4, and a vibration pulley 13 is rotatably installed on the end of the frame 1 away from the driving motor 2, and one end of the vibration pulley 13 passes through the frame 1, the vibration pulley 13 is connected to the output shaft of the vibration barrel 15, and the vibration barrel 15 and the vibration pulley 13 are flexibly connected, and a second belt 14 is arranged between the vibration pulley 13 and the secondary pulley 12, and the diameter of the secondary pulley 12 is larger than the diameter of the vibration pulley 13.

[0038] When the eccentric shaft 6 rotates, it will drive the secondary pulley 12 to rotate together, so that the second belt 14 drives the vibration pulley 13 to rotate. Through the diameter difference between the secondary pulley 12 and the vibration pulley 13, the eccentric block in the vibration barrel 15 is driven to rotate faster, so that the screening frame 16 vibrates more vigorously, and can screen while crushing the material.

[0039] A conveyor belt 19 is provided on the inner side of one end of the frame 1 away from the movable pressure plate 7, and the conveyor belt 19 is located directly below the movable jaw pressure plate 8 and the fixed jaw pressure plate 9, and the movable jaw pressure plate 8 and the fixed jaw pressure plate 9 are located directly above the screening frame 16.

[0040] As the screen plate 17 vibrates, qualified materials will fall onto the conveyor belt 19, and the side baffles 18 will cause the fallen materials to slide along the inclined surface to the center of the conveyor belt 19, so that the crushed and screened materials will not fall into the gap between the conveyor belt 19 and the frame 1, reducing the probability of material blocking the conveyor belt 19 and reducing material loss.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
