Description

A double rotor hammer sand making machine with adjustment device

technical field

The invention belongs to a grinding and crushing equipment for massive raw materials such as stones and ore, in particular to a double-rotor hammer-type sand making machine with an adjusting device.

Background technique

At present, in the field of crushed stone shaping and sand making, the main types of sand making machines are horizontal fine crusher, impact crusher, vertical shaft impact sand making machine, etc. The horizontal fine crusher and the impact crusher work on the principle of striking and counterattacking the stone, and the grain shape of the products is poor, most of which are "needle-shaped", and the actual use effect is very poor, and cannot be applied to mortar or concrete. The vertical shaft impact sand making machine adopts the principle of impact and grinding to make sand. Although the finished product can meet the requirements of use, its structure is complex and the cost is high, which greatly increases the user's initial investment cost and increases the user's use cost.

SUMMARY OF THE INVENTION

The technical task of the present invention is to provide a double-rotor hammer-type sand making machine with an adjustment device in view of the above deficiencies in the prior art.

The technical scheme adopted by the present invention to solve the technical problem is: a double-rotor hammer sand making machine with an adjustment device, including a motor, a frame, a feeding device, a crushing cavity, a crushing cavity cover, a hydraulic cylinder, and a main lining plate , the first auxiliary lining plate, the second auxiliary lining plate, the adjusting screw, the rotor, the dust removal chamber and the discharge opening, wherein the crushing cavity includes a left crushing cavity and a right crushing cavity, wherein the discharge opening is located at the bottom of the frame At the middle position, the feeding device is arranged at the middle position of the top of the frame, the dust chamber is arranged at the central position inside the frame, wherein the left crushing chamber and the right crushing chamber are arranged inside the frame and are related to the feeder. The material device and the dust removal chamber are symmetrical, and the rotor is arranged in the left crushing chamber and the right crushing chamber and is driven by a motor.

Further, one end of the main lining plate is movably fixed on the crushing cavity cover through a pin shaft, and the other end is fixed at the bottom of the crushing cavity cover through an adjusting screw rod.

Further, the first auxiliary lining plate is fixedly arranged on the top of the interior of the crushing chamber cover, the second auxiliary lining plate is fixedly arranged on both sides of the dust chamber, and the second auxiliary lining plate is arranged on both sides of the dust chamber. Inverted "eight" shape.

Further, the bottom of the crushing chamber cover is hingedly connected to the frame, and the top is movably connected to a hydraulic cylinder arranged at the bottom of the frame.

Further, the rotor is provided with at least two groups of hammer heads along the radial direction.

Further, the bottom of the dust chamber is provided with a flue gas channel which is inclined downward.

The beneficial effects of the invention are as follows: the stone is divided into the left and right crushing chambers through the central feeding port, and under the action of the high-speed rotating hammer head, the stone is initially crushed, and then hits the counterattack device to make the material undergo secondary crushing and rebound. The high-speed friction between the stones is reshaped, and an adjustment device is arranged behind the counterattack device, which can adjust the gap between the counterattack device and the hammer head to compensate for the wear of the hammer head or adjust the product gradation. The lining layer can form the grinding and crushing between the stones. In this way, after many times of impact and continuous cycle crushing and grinding, the stones are fully crushed, and under the action of grinding, the crushed products have good particle shape, and most of them have a nearly cubic structure. The content of needle-like particles is very small, and the product gradation is reasonable, which can meet the requirements of machine-made sand.

Because the overall structure of the equipment is relatively simple, the raw material and processing costs of the equipment are greatly reduced compared with the vertical shaft impact sand making machine, which effectively saves the user's use cost.

The dust removal device can be connected to an external dust collector, which eliminates the phenomenon of dust flying during the operation of the sand making machine and meets the requirements of green environmental protection.

The hydraulic opening device can be opened when the staff inspects and maintains the equipment, which reduces the labor intensity of the staff and greatly improves the efficiency.

Detailed ways

The present invention is described in detail below with reference to the accompanying drawings:

As shown in Figure 1, Figure 2 and Figure 3, a double rotor hammer sand making machine with adjustment device includes a motor 13, a frame 1, a feeding device 3, a crushing chamber 11, a crushing chamber cover 2, a hydraulic cylinder 12. The main lining plate 8, the first auxiliary lining plate 7, the second auxiliary lining plate 9, the adjusting screw 6, the rotor 5, the dust removal chamber 4 and the discharge port 10, wherein the crushing chamber 11 includes a left crushing chamber and a right Crushing cavity, wherein the discharge port 10 is located at the middle position of the bottom of the frame 1, the feeding device 3 is arranged at the middle position of the top of the frame 1, and the dust chamber 4 is arranged at the center position inside the frame 1 , wherein the left crushing cavity and the right crushing cavity are arranged inside the frame 1 and are symmetrical with respect to the feeding device 3 and the dust removal chamber 4 , and the rotor 5 is arranged in the left crushing cavity and the right crushing cavity and is driven by the motor 13 .

Further, one end of the main lining plate 8 is movably fixed on the crushing chamber cover 2 by a pin shaft, and the other end is fixed on the bottom of the crushing chamber cover 2 by the adjusting screw 6 .

Further, the first auxiliary lining plate 7 is fixedly arranged on the top of the interior of the crushing chamber cover 2 , the second auxiliary lining plate 9 is fixedly arranged on both sides of the dust chamber 4 , and the The second auxiliary lining plate 9 is in the shape of an inverted "eight".
