Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of carriage cleaning equipment, especially to the carriage surplus material crushing device. BACKGROUND

[0002] In the production process, enterprises such as ports, power plants and mines will purchase a large amount of blocky or powdery mineral resources as production raw materials, such as coal. When bulk raw materials are purchased in batches, trains or heavy trucks are mainly used as transport tools. During transportation, due to moisture and vibration, the bulk material will generally adhere tightly to the carriage. In addition, under low temperature conditions, raised frozen coal may also form on the bottom of the carriage.

[0003] In the prior art, most devices can only simply collect the surplus material in the carriage, but there may be frozen coal blocks with a high protrusion height on the bottom of the carriage. If the device continuously collects surplus material in the same height direction, the frozen coal blocks with a high height may wear or damage the device, reducing the service life of the device. SUMMARY

[0004] The embodiment of the application provides a carriage surplus material crushing device which can automatically raise the crushing roller when encountering a frozen coal block with a high height, thereby protecting the carriage surplus material cleaning machine, prolonging the service life of the carriage surplus material cleaning machine, and ensuring the cleaning efficiency of the carriage surplus material.

[0005] The embodiment of the application provides a carriage surplus material crushing device, which comprises a crushing roller, a hydraulic oil cylinder and an adapter frame. The crushing roller is horizontally installed on the lower part of the front side of a carriage surplus material cleaning machine and is provided with a milling head on the surface. The hydraulic oil cylinder has at least two, and at least two hydraulic oil cylinders are hingedly arranged on the front side of the carriage surplus material cleaning machine in the same height direction and are located above the crushing roller. The telescopic shaft of the hydraulic oil cylinder is connected to the crushing roller through the adapter frame. The adapter frame comprises a plurality of groups of first supports, second supports and spring shock absorbers corresponding to the hydraulic oil cylinder. The first support and the second support are respectively hingedly connected to the carriage surplus material cleaning machine through the inner side end. The telescopic shaft of each hydraulic oil cylinder is hingedly connected to the top of the outer side end of each first support. The bottom of each first support is connected to each second support through the spring shock absorber. The crushing roller is installed in the second support.

[0006] In a possible implementation, the crushing roller is composed of a plurality of gap-fitted segment rollers. Each segment roller is installed in each second support, and a rotary motor is installed in the second support. The output end of the rotary motor is fixedly sleeved with a driving wheel. The middle part of the segment roller is fixedly sleeved with a transmission wheel. The driving wheel is drivingly connected to the transmission wheel through a transmission member.

[0007] In a possible implementation, the rotating motor is a hydraulic motor, the driving wheel and the transmission wheel are gears, and the transmission member is a chain plate.

[0008] In a possible implementation, the milling head is in an S-shaped distribution and is arranged around the surface of each segment roller.

[0009] In a possible implementation, the hydraulic cylinders are four, and the four hydraulic cylinders are uniformly distributed along the axial direction of the crushing roller.

[0010] Advantages: Compared with the prior art, the wagon residue crushing device provided by the application is connected with the crushing roller through the hydraulic cylinder and the adapter frame. When the crushing roller contacts a high frozen coal block, the crushing roller provides a reverse thrust to the hydraulic cylinder to increase the oil pressure of the hydraulic cylinder, and the hydraulic cylinder retracts to maintain the original oil pressure range, thereby increasing the height of the crushing roller and protecting the crushing roller. The hydraulic cylinder has a plurality of hydraulic cylinders, and each hydraulic cylinder is connected to the crushing roller through the adapter frame, which can improve the stability of the crushing roller. The spring shock absorber can reduce the vibration and impact of the wagon residue cleaning machine.

[0011] The crushing roller is composed of a plurality of gap-matched segment rollers, and each hydraulic cylinder is connected to each segment roller through the adapter frame. When a high frozen coal block is encountered locally, only the height of the corresponding segment roller can be increased, the work is more flexible, the workload of the hydraulic cylinders in other parts not encountering high frozen coal blocks can be reduced, the work is targeted, the cost can be saved, and the service life of the cleaning machine can be prolonged.

[0012] The milling head is in an S-shaped distribution and is arranged around the surface of each segment roller, which can better adapt to the conditions and operation requirements of the wagon bottom, helps to achieve more uniform milling effect, and can more efficiently clean the wagon bottom residue.

[0013] These and other objects, features and advantages of the present application will become apparent with reference to the following detailed description. BRIEF DESCRIPTION OF DRAWINGS
