Description
Technical Field
[0001] The invention relates to the technical field of sand and gravel crushing, in particular to an environmentally friendly sand and gravel crushing device for processing cement poles. Background Art
[0002] Crusher is widely used in the fine and coarse grinding of metal and non-metallic ores, cement, refractory materials, abrasives, glass raw materials, building aggregates, artificial sand making and various metallurgical slags. Sand and gravel refers to a loose mixture of sand and gravel. During the processing, a crusher is also needed. With the rapid development of the power and telecommunications industry, more and more cement poles are used. Cement poles are mainly composed of steel bars and concrete, so they are also called reinforced concrete cement poles. They are mainly used as cable support pillars in the power, communication, railway, petroleum and other industries. Before processing cement poles, a large amount of sand and gravel raw materials are needed, and the sand and gravel raw materials need to be crushed.
[0003] When the crusher is crushing sand and gravel, the poor fit between the crushing rollers causes the sand and gravel to slip easily between the crushing rollers, which affects the crushing of the sand and gravel, causing the incompletely crushed and crushed sand and gravel to be mixed together for transportation. At the same time, a large amount of dust will be generated in the crushing process, causing environmental pollution. Summary of the invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an environmentally friendly cement pole processing sand and gravel crushing equipment, including a frame, the number of the frames is two, a shell is arranged on the opposite sides of the frame, a feed pipe is fixedly connected to the middle of the two ends of the shell, the frame is symmetrically arranged with the shell as the center, the feed pipe is fixedly connected to the frame at one end away from the shell, a motor is fixedly connected to the side of the frame away from the feed pipe, a rotating shaft is fixedly connected to the output end of the motor, the rotating shaft passes through the shell, and a discharge port is opened at the bottom of the shell;
[0005] A connecting piece, the connecting piece is fixedly connected to the feed pipe and is arranged inside the shell;

[0007] The crushing assembly includes a connecting ring, the inner wall of the connecting ring is fixedly connected to the middle of the outer side of the rotating shaft, and a fixed plate is fixedly connected to the outer side of the connecting ring. Sand and gravel are added to the inside of the feed pipe, and the sand and gravel enter the inside of the spiral plate through the feed pipe. The sand and gravel move toward the middle along the spiral plate, so that the sand and gravel enter the gap between the crushing assembly and the connecting piece. At this time, the rotating shaft drives the connecting ring to rotate, and the connecting ring drives the fixed plate and the connecting plate to rotate, so that the connecting plate drives the fan-shaped block to rotate, and then the convex block on the outer side of the fan-shaped block drives the sand and gravel to move, so that the sand and gravel in the gap are broken under the collision, friction and possible pressure with the inner wall, and the spring is set The plate utilizes the elastic properties of the spring plate to make the outer fan-shaped block fit tightly with the sand and gravel, thereby increasing the friction force. Therefore, when the crushing assembly crushes the sand and gravel, the sand and gravel are not easy to slip between the protrusion and the connecting piece, so that the crushing can be better performed, thereby ensuring that the material is fully crushed inside the connecting piece, thereby improving the crushing efficiency.

By arranging the extension plate, it is prevented that the spring plate is in a state of excessive deformation for a long time, which causes the elastic force of the spring plate to fail. The extension plate is located at the adjacent side of the connecting plate close to the spring plate. The outer side of the rotating shaft is fixedly connected with a circular plate. There are two circular plates, and the two circular plates are symmetrically arranged with the fan-shaped block as the center.

Then, under the elastic force of the bending plate, the fan-shaped block is reset, and the connecting plate passes through the middle cylinder through the through hole. The extension plate is located inside the middle cylinder. The outer side of the rotating shaft is fixedly connected with a swivel, and the swivel is fixedly connected to the circular plate. The outer side of the swivel is fixedly connected with an arc plate. The motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral plate to rotate, thereby driving the sand and gravel to move toward the middle crushing assembly. At the same time, the rotating shaft drives the swivel and the arc plate to rotate, so that the sand and gravel move along the arc plate toward the edge of the circular plate, thereby smoothly entering the middle gap between the crushing assembly and the connecting part, and passing through The rotation of the circular plate and the arc plate can disperse the sand and gravel more evenly to the gap, so that the amount of sand and gravel entering the crushing or processing link each time is relatively stable, which can ensure that the subsequent crushing process can be carried out stably and avoid problems such as unstable equipment load and uneven processing effects caused by uneven feeding. There are multiple arc plates, and the multiple arc plates are evenly distributed with the rotating ring as the center.

During the crushing process, smaller particles can be screened out through the square holes, while larger particles remain in the shell and continue to be crushed. By setting the square holes, when the ore is crushed to a certain extent, the ore particles that meet the particle size requirements can be discharged through the square holes, which can effectively avoid excessive crushing, thereby saving energy and time. There are multiple square holes, and the multiple square holes are evenly distributed with the shell as the center. The inner wall of the shell is fixedly connected with a square plate.

[0014] 2. The environmentally friendly cement pole processing sand and gravel crushing equipment can input the crushed sand and gravel from two directions by feeding at both ends simultaneously, avoiding the problem of concentrated accumulation of sand and gravel and blockage of the feed channel that may occur at a single feed port, making the feeding process smoother, reducing equipment downtime and waiting time caused by poor feeding, and improving overall production efficiency.

Under the connecting action of the middle rod 86, the adjacent fan-shaped blocks 84 rotate, so that the gap between the fan-shaped block 84 and the connecting piece 5 becomes larger, which is convenient for the passage of sand and gravel. Then, under the elastic force of the bending plate 812, the fan-shaped block 84 is reset.
[0040] The rotating shaft 6 drives the rotating rod 9 to rotate, and the rotating rod 9 rotates and contacts the inclined groove 44 on the extension rod 43, so that the extension rod 43 is forced to move, so that the extension rod 43 drives the protective cover 41 to slide on the sliding rod 45. When the rotating rod 9 rotates away from the extension rod 43, the protective cover 41 is reset under the elastic force of the spring 46, so that the protective cover 41 moves back and forth left and right during the rotation of the rotating rod 9. At this time, the brush 42 inside the protective cover 41 cleans the square hole 53 to prevent the square hole from being blocked.
[0041] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
