Description

A double-toothed roller crusher with protection function

technical field

The utility model relates to the field of crusher equipment, in particular to a double-toothed roller crusher with protection function.

Background technique

Crusher is suitable for metallurgy, mining, chemical industry, cement and other industrial sectors. Every year, a large amount of raw materials and reused waste need to be processed by crusher. For example, in a concentrator, in order to separate the useful minerals in the ore, it is necessary to use a crusher to crush the raw ore to the particle size required by the grinding process. It is necessary to use crushing machinery to crush the raw materials to the particle size required by the next step.

At present, the crusher has been successfully applied in the crushing of coal gangue. However, in limestone mines, due to the relatively hard material and high chunk rate, the crusher is prone to breakage of the tooth crown and the fracture of the tooth ring during the application process. It is difficult to replace, the drive shaft of the crushing roller and the inner ring of the bearing seat are easy to crack, and after crushing, the size of the ore varies, and subsequent separation and filtration are required, which increases production costs and labor, and the efficiency is very low.

Utility model content

The purpose of the utility model is to provide a double-toothed roller crusher with a protection function, which has a simple structure, can crush soft ores, filter hard ores, and separate and transport the ores according to their sizes after crushing.

The utility model is realized through the following technical solutions:

The motor that turns the drive shaft. Among them, the size of the fixed toothed roller and the moving toothed roller are equal, and the toothed roller surfaces of the fixed toothed roller and the moving toothed roller are set opposite to each other, and an appropriate gap is left in the middle, and the material is crushed by rolling extrusion between the toothed roller surfaces. The toothed roller box is a reduced version of the chute box with the same style, but it is used to be set in the chute box. The middle shafts of the fixed toothed roller and the moving toothed roller are equipped with a drive shaft to drive the toothed roller to rotate. The drive shaft and the machine The connection between the side wall of the shell and the inner wall of the toothed roller box is equipped with a bearing seat, which is used to connect the drive shaft and facilitate the rotation of the drive shaft. The motor on the side wall of the casing and the toothed roller box is used to drive the first drive shaft and the second The second driving shaft rotates, so that the motor drives the driving shaft, and the driving shaft drives the toothed roller to rotate, so that the material can be crushed.

The working principle is:

The utility model selects the elastic force strength of the spring before use, and the strength of the spring is equal to the bearing force of the fixed toothed roller and the moving toothed roller. If the hardness of the ore is low, it will be crushed normally. If the hardness of the ore is high, the spring will contract and drive the moving gear roller to shrink, so that the ore with high hardness will fall directly without crushing. It achieves the purpose of crushing soft ore and filtering hard ore, and avoids the disadvantage of forcibly crushing hard ore and causing tooth roller damage.

Further, the top and bottom of the toothed roller box are slidably connected to the inner wall of the chute box through slide rails. The function of the slide rail connected between the two is equivalent to the slide rail on the side of the drawer. When the toothed roller box and the chute box have a horizontal relative displacement under the action of pressure, the slide rail can facilitate the movement of the toothed roller box and avoid toothed roller box. The roller box is stuck in the chute box during the movement.

Further, the discharge port is arranged on the side wall of the casing, and a sieve plate inclined toward the discharge port is provided under the moving toothed roller and the fixed toothed roller, and small holes are provided on the sieve plate. The sieve plate is connected to the side wall of the casing, and the sieve plate can extend out of the discharge port. The size of the small holes on the sieve plate is determined according to the size of the crushed stones required. When in use, the sieve plate falls from between the fixed toothed roller and the moving toothed roller. The ore falls on the sieve plate first, and the ore that meets the requirements after crushing falls from the small hole, while the ore that does not meet the specifications rolls out from the discharge port along the sieve plate, which well achieves the goal of filtration and separation. Effect.

Further, the bottom of the sieve plate is provided with a vibrating motor to drive the sieve plate to vibrate. The vibration motor is installed at the bottom of the sieve plate. The essence of the vibration motor is a motor with a piston that can move up and down. When the motor is turned on, the piston moves up and down. When the frequency is high, it can drive the sieve plate to vibrate. Good filter separation of gravel.

Further, a conveying device for conveying screening materials is provided under the sieve plate. The conveying device is used to accept the ore falling from the sieve plate, and convey the ore to the outside of the casing.

Further, foot pads are provided at the bottom of the casing. The material of the foot pad has both certain elasticity and high strength. Rubber is preferred, which can prevent the equipment from vibrating and causing serious damage to the equipment during use.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) The utility model realizes the soft ore crushing and hard ore filtering of the fixed toothed roller and the moving toothed roller through the movable structure composed of the chute box, the toothed roller box and the spring, and avoids the tooth damage caused by the forced crushing of the hard ore. Disadvantages of roller damage;

(2) The sieve plate installed under the fixed toothed roller and the moving toothed roller of the utility model can separate the ore that meets the size specification from the ore that does not meet the size, and it is very convenient to separate and filter during the production process;

(3) The vibration motor added under the sieve plate of the utility model can make the sieve plate filter and separate ore better;

(4) The transmission device added under the sieve plate of the utility model can transport the separated ore that meets the specification requirements to the outside of the casing, and the whole process is automatically completed, which is convenient to use.
