Lump coal crusher with quantitative control function

Abstract

The invention belongs to the technical field of lump coal crushers and particularly relates to a lump coal crusher with the quantitative control function, and aims to solve the problems that the existing lump coal crusher cannot timely control the descending speed of lump coal and is unstable in feeding to cause blockage easily, so that the device is likely to be damaged, and the service life is affected. To solve the technical problems, the invention discloses the lump coal crusher with the quantitative control function. The lump coal crusher with the quantitative control function comprises abase, an upper machine body, a lower machine body, a conveyor belt, a weighing valve, a hydraulic control cabinet, a motor fixing table, a hydraulic cylinder, an eccentric shaft, a second gear, a floating bush and an eccentric shaft sleeve, wherein the lower machine body is positioned between the hydraulic control cabinet and the motor fixing table; the top of the lower machine body is fixedly connected with the hydraulic cylinder through a bolt; the top of the hydraulic cylinder is connected with the upper machine body through a hydraulic rod; and the eccentric shaft is mounted at the bottomof the interior of the lower machine body. The lump coal crusher has the effects of reasonably controlling the quantity of lump coal, adjusting the space of the machine body device and better treating the size effect of the lump coal.

Description

technical field [0001] The invention belongs to the technical field of coal block crushers, and in particular relates to a coal block crusher with quantitative control. Background technique [0002] With the development of society, the use of crushers plays an increasingly important role in metallurgy, construction, road construction, chemical industry and other industries. At present, in thermal power generation and chemical industry, coal is the main fuel. To ensure the safety of coal Full combustion is generally to break the coal into pulverized coal to ensure the full combustion of coal and reduce the emission of harmful gases. The crushing effect is not good, and the requirement of full combustion cannot be met. Moreover, most of the existing crushers have an integrated fuselage, which may cause internal blockage due to untimely crushing, which not only causes damage to the crushing device, but also affects the performance of the crusher. service life.

Problems solved by technology

[0003] According to the deficiencies of the prior art above, the technical problem to be solved by the present invention is to propose a coal crusher with quantitative control. The falling speed of the coal block cannot be controlled in time, and the feeding instability is easy to cause blockage, which is easy to cause damage to the device and affect the service life. It has the effect of reasonably controlling the number of coal blocks, adjusting the space of the fuselage device, and better handling the size of the coal block.
