Cone crusher with upper cone shock absorption function

Abstract

The invention discloses a cone crusher with an upper cone shock absorption function. The cone crusher comprises an upper rotary cone mechanism, a lower fixed cone body and a driving device. The upperrotary cone mechanism comprises an upper rotary cone body capable of swinging, a deflection swinging device, a moving frame and a plurality of upper shock absorption devices. The deflection swinging device and the driving device are in driving connection. The deflection swinging device drives the upper rotary cone body to rotate eccentrically. The deflection swinging device is fixedly arranged onthe moving frame. By arranging the moving frame, the upper shock absorption devices and a lower shock absorption device, the situation that the upper cone body and the lower cone body are impacted seriously when meeting suddenly added hard materials with different grades during crushing can be effectively avoided, the impact force is reduced to the minimum extent, and the equipment is not or lessdamaged by the impact force. Meanwhile, the cone crusher is simple in structure, practical, more beneficial to daily maintenance, and more suitable for practical production and application of the heavy dust industry of material crushing.

Description

technical field [0001] The invention relates to the production field of material crushing equipment, more specifically to a cone crusher with an upper cone for shock absorption. Background technique [0002] The annual crushing materials of crushers in the world reach as many as tens of billions of tons, and the annual crushing of various materials in my country alone is about 1.8 billion tons, including about 240 million tons of iron ore, more than 100 million tons of non-ferrous metal ores, and non-metallic ores. 230 million tons of minerals, 30 million tons of chemical minerals, 400 million tons of cement, 470 million tons of limestone for building materials, power consumption of 25-000 million kW-h, and steel consumption of about 2.5 million tons. Therefore, the production of energy-saving, high-tech crushers in the crusher industry has become a major trend in the development of the crushing machinery industry in the future. [0003] The design of the cone crusher has a ...

Problems solved by technology

Cone crushers used in mine mineral crushing operations often have a problem in actual use, that is, in the process of crushing materials, the materials are easily mixed with metallic substances that are harder than mine ore materials. During the process, the hard material will seriously damage the crushing equipment, affect the normal operation of the equipment, and reduce the service life of the cone crusher.

[0005] In order to overcome the above problems, many types of cone crushers have appeared in the industry, such as spring cone crushers, hydraulic cone crushers or high-efficiency cone crushers, such as the Chinese patent authorization announcement number: CN102430446 B discloses a cone crusher, The design structure of this kind of mechanical equipment is completely different from the traditional cone crusher. They are not only suitable for crushing materials with various hardness, but also have a very high crushing efficiency. However, they also use the upper fixed cone, The crushing method matched with the lower movable cone, because the lower movable cone is not only large in size and heavy in weight, but also consumes a lot of energy when rotating. At the same time, when it encounters materials with different levels of hardness that suddenly increase, its inertia is large, The damage to the equipment will increase accordingly
