Description

Modular crushing device Technical Field The utility model relates to the technical field of crushing equipment, in particular to a modular crushing device. Background Primary crushing in opencut mining, also known as primary crushing, is the first link in the ore or coal crushing process, typically performed near the stope, in order to crush large pieces of raw ore or coal rock after blasting or mining to a small particle size for subsequent transportation, washing or further processing. For a double-toothed roller screening crusher, 3000-12000 tons of raw coal can be subjected to primary crushing treatment per hour, the feeding granularity is usually less than or equal to 1.8 meters (three-dimensional size), and the discharging granularity is usually less than or equal to 300mm (three-dimensional size). The double-toothed roller screening crusher is designed with two crushing rollers and one crushing tooth, and the space formed between the crushing teeth and the crushing rollers is commonly called as a crushing space, and the crushing space is a key point for controlling the granularity of discharged materials. At present, after the design of the double-toothed roller screening crusher is finished, the crushing space of the double-toothed roller screening crusher is shaped and cannot be changed, and in the actual use process, the granularity graduation, the compressive strength, the gangue content and the water content of raw coal feed are different, for example, the problem that the super granularity (more than 10 percent) is easy to appear when the design of the crushing space is improper, the yield of subsequent procedures is influenced, the blocking is easy to cause, and the crushing process is influenced. Disclosure of utility model In order to solve the problem that blockage is easily caused by the fixation of a crushing space of an existing double-toothed roller screening crusher, the utility model provides a modular crushing device, which comprises a platform, wherein a crushing opening is formed in the platform, two bases are arranged in the crushing opening, crushing beams are arranged on the two bases, a plurality of crushing teeth are detachably connected to the crushing beams, and the crushing teeth are arranged along the length direction of the crushing beams. The utility model further provides that a plurality of crushing teeth are arranged in a staggered manner. The utility model is further characterized in that two adjacent crushing teeth are in contact with each other, and a plurality of crushing teeth are arranged to cover the top of the crushing beam. The utility model is further characterized in that a backing plate is arranged between the crushing beam and the base. The utility model is further characterized in that baffles are arranged at two ends of the crushing beam. The beneficial effects of the utility model are as follows: 1. The crushing beam is of an independent structure, flexible in installation and convenient in application, the crushing teeth can be detachably connected, the purpose of independently detaching and replacing the crushing teeth can be achieved, the purpose of changing the crushing space can be achieved by adjusting and installing the crushing teeth with different tooth shapes, and then the control of granularity is achieved. 2. Through utilizing a plurality of broken teeth to cover the top of broken roof beam, can avoid the top and the feeding contact of broken roof beam, and then avoid broken roof beam main structure to appear wearing and tearing. Drawings Fig. 1 shows a schematic view of the structure of the present utility model mounted on a platform. Fig. 2 shows a schematic structural diagram of the present utility model. Fig. 3 shows a structural position diagram of the present use novel and crushing roller. The device comprises a reference numeral 1, a platform 2, a base 3, a crushing beam 4, crushing teeth 5, a backing plate 6 and a baffle. Detailed Description Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model. The utility model provides a modular crushing device which comprises a platform 1, wherein a crushing opening is formed in the platform 1, mounting beams are welded in the crushing opening, bases 2 are welded on the mounting beams, and two bases 2 are arranged.
