Vertical shaft type sand making device capable of fully crushing raw materials

Abstract

The invention relates to the technical field of gravel preparation, and provides a vertical shaft type sand making device capable of fully crushing raw materials. The vertical shaft type sand making device comprises a body, an inner wall of the body is movably connected with a feeding rotating disc, an inner wall of the feeding rotating disc is provided with a track, and an inner wall of the trackis elastically connected with a spring. According to the vertical shaft type sand making device capable of fully crushing the raw materials, when the feeding speed is higher than the discharging speed, the raw materials in the sand making machine are continuously accumulated, the pressure borne by the sand making machine is increased, the rotating speed of a centrifugal rotor is reduced, the centrifugal force borne by the raw materials is reduced, and the phenomenon of incomplete crushing occurs; and at the moment, the rotating speed of the centrifugal rotor is reduced, the centrifugal forceborne by a rack block in the feeding rotating disc is reduced, the rack block moves under the tension of the spring, the rack block drives a conversion wheel to enable a baffle to rotate and move, a feeding inlet is reduced, the feeding amount of the raw materials in unit time is reduced, incomplete crushing and machine damage are caused, the size of the feeding inlet is changed through the changeof the centrifugal force, and the raw materials are completely crushed.

Description

technical field [0001] The invention relates to the technical field of sand and gravel preparation, in particular to a vertical shaft type sand making equipment capable of fully crushing raw materials. Background technique [0002] Sand making machine is a machine used for crushing soft, medium hard and extremely hard ore materials. It is often used in smelting, building materials, roads, railways, water conservancy and chemical industries. With the development of the times, traffic construction continues to increase, and traffic The construction of roads is inseparable from the supply of a large amount of high-quality sand and gravel, and the supply of natural sand and gravel has long been in short supply. Sand making machines have become one of the main sources of supply of sand and gravel. [0003] In the existing technology, during the production process of the sand making machine, due to various reasons, the feeding speed of the sand making machine is faster than the di...

Problems solved by technology

[0003] In the existing technology, during the production process of the sand making machine, due to various reasons, the feeding speed of the sand making machine is faster than the discharging speed, and a large amount of raw materials are accumulated, which seriously affects the rotation of the vertical shaft and causes the machine to be stuck, and the sand making machine It is inevitable that there will be some relatively large products in the production of the machine, which may block the machine and cause damage to the machine. Therefore, a vertical shaft sand making equipment that can fully crush raw materials came into being.
