Description

Technical Field

[0001] This utility model relates to the field of ore crushing, and in particular to an adjustable-height jaw double-roller combined unit. Background Technology

[0002] In the process of ore mining, large pieces of ore need to be crushed into smaller pieces to facilitate transportation and subsequent processing. Jaw crushers are widely used due to their simple structure, long service life, and good crushing effect. However, in actual use, the crushing output of a single jaw crusher is relatively low. To improve crushing efficiency, many companies will set up two jaw crushers side by side. In addition, the discharge port of the jaw crusher is usually located at the bottom of the unit, and the height of the jaw crusher is fixed and cannot be adjusted according to the usage. Therefore, in order to improve practicality and increase crushing efficiency, an adjustable-height jaw double-roller combination unit is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable-height jaw double-roller combined unit. This device is equipped with two crushing chambers that can simultaneously crush ores and other materials. The height of the device can be adjusted according to actual usage conditions, and it has the advantages of high practicality and high crushing efficiency.

[0004] The purpose of this utility model is to provide an adjustable-height jaw double-roller combined unit, including a shell, a trapezoidal block fixedly arranged at the center of the shell, stationary jaw plates fixedly arranged on both sides of the trapezoidal block, the trapezoidal block dividing the space inside the shell into two crushing chambers, two eccentric components fixedly arranged at the top of each of the two crushing chambers, and a movable jaw plate fixedly connected to the bottom of each of the two eccentric components, two motor mounting seats fixedly arranged on both sides of the shell, two drive components fixedly arranged on each of the two motor mounting seats, and the two drive components are fixedly connected to the two eccentric components respectively, buffer components are fixedly arranged between the left and right sides of the shell and the movable jaw plates, a base is arranged at the bottom of the shell, and a lifting component is fixedly arranged between the base and the shell.

[0005] Furthermore, the lifting assembly includes a connecting block and multiple hydraulic telescopic rods. There can be two connecting blocks, both of which are fixedly installed on both sides of the bottom of the housing. The fixed ends of the multiple hydraulic telescopic rods are fixedly installed on the top surface of the base, and the extended ends of the multiple hydraulic telescopic rods are fixedly connected to the bottom of the connecting block.

[0006] Furthermore, the eccentric assembly includes a rotating shaft and two eccentric bearings. The rotating shaft is fixedly fitted with seated bearings near both ends. The rotating shaft is fixedly connected to the housing through the seated bearings. The two eccentric bearings are fixedly mounted on the rotating shaft inside the seated bearings. The bottom of the eccentric bearings is fixedly connected to the moving jaw plate.

[0007] Furthermore, the drive assembly includes two servo motors and two pulleys. The two servo motors are respectively fixedly mounted on the top of the motor mounting brackets on both sides of the housing. The two pulleys are fixedly mounted at both ends of the rotating shaft. The output ends of the two servo motors are fixedly connected with drive teeth, and belts are fitted on the drive teeth and pulleys.

[0008] Furthermore, the buffer assembly includes two horizontal plates and a nut. The two horizontal plates are respectively fixedly mounted on the outside of the moving jaw plate. Multiple connecting shafts are rotatably mounted on the two horizontal plates. One end of the connecting shaft is rotatably connected to the horizontal plate, and the other end passes through the housing and is located outside the housing. The outer end of the connecting shaft is threaded. The nut is rotatably mounted on the thread outside the connecting shaft, and one side of the nut is in contact with the housing.

[0011] Furthermore, a toothed groove is provided on the inner side of the belt to mate with the pulley and the drive tooth.

[0012] The working principle and usage principle of this utility model are as follows: The ore to be crushed is simultaneously fed into two crushing chambers. Two drive components control the operation of two eccentric components, which in turn control two moving jaw plates to perform eccentric movements. When the two moving jaw plates perform eccentric movements, they move towards the stationary jaw plate and squeeze the ore between the moving jaw plate and the stationary jaw plate. The lifting component can adjust the height of the device. In the buffer component, the angle between the moving jaw plate and the stationary jaw plate is adjusted by rotating and tightening the nut at different positions on the thread at the other end of the connecting shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the overall height of the device can be adjusted to meet various usage needs, and the double-roller linkage crushing improves the crushing effect, while the two crushing chambers crush the ore separately, increasing the crushing efficiency of the device.

The inner side of the belt 75 is provided with tooth grooves 76 that cooperate with the drive gear 74 and the pulleys 73 to increase the transmission effect.

[0023] according to Figure 3As shown, the buffer assembly 8 includes two horizontal plates 81 and a nut 84. The two horizontal plates 81 are respectively fixedly installed on the outside of the moving jaw plate 4. Multiple connecting shafts 82 are rotatably installed on the two horizontal plates 81.
