Description

Technical Field

[0001] The utility model relates to the technical field of waste concrete processing equipment, in particular to a waste concrete crusher. Background Art

[0002] A waste concrete crusher is a device specially used to process waste concrete. Its main function is to crush waste concrete into granular aggregates for easy recycling and reuse. There are many types of waste concrete crushers. Different types of waste concrete crushers are selected according to different working conditions and working environments. Waste concrete crushers are roughly divided into jaw crushers, hammer crushers, cone crushers and mobile crushing stations, which are several commonly used concrete crushers.

[0003] When the existing waste concrete crushers are in use, most of them feed the waste concrete into the crushing box through a feed pipe, and the waste concrete is processed into particles through extrusion or hammering inside the crushing box. However, when the waste concrete is extruded or hammered, the crushed waste concrete will splash to the outside, and the splashed concrete will hit the operator, causing physical harm to the operator. For this reason, we provide a waste concrete crusher to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a waste concrete crusher, including a frame 1, a feed pipe 3 and a baffle 4, the frame 1 is used to carry the required components, a crushing box 2 is arranged above the frame 1, and two crushing rollers 5 are symmetrically arranged inside the crushing box 2. The two crushing rollers 5 rotate with each other to squeeze and crush the waste concrete, and the crushing rollers 5 are driven to rotate by power provided by an external motor.

[0026] A feed pipe 3 is fixedly connected to one side of the crushing box 2. The feed pipe 3 has an upward tilt angle, which is convenient for concrete to slide into the crushing box 2. The waste concrete is sent into the crushing box 2 through the feed pipe 3. The hopper outside the feed pipe 3 is convenient for filling the waste concrete, and the feed pipe 3 is connected to the inside of the crushing box 2. A baffle 4 is arranged inside the feed pipe 3. A limit block 8 is fixedly connected to the inner wall of the feed pipe 3. One side of the limit block 8 contacts the outer surface of the baffle 4 to prevent the baffle 4 from losing its function of blocking the splashed concrete blocks at an excessive angle after resetting. The baffle 4 is always at a reasonable angle by limiting the reset angle of the baffle 4 through the blocking block. The inner side of the feed pipe 3 is movably connected with a support rod 6 at a fixed point. The outer surface of the support rod 6 is fixedly connected to one side of the baffle 4. After the waste concrete is put into the feed pipe 3, the waste concrete slides into the crushing box 2 due to the influence of the tilt angle. The waste concrete pushes the baffle 4 to swing upward. After the concrete is out of contact with the baffle 4, the reset mechanism 7 drives the baffle 4 to reset. The baffle 4 closes the feed pipe 3 channel, so that the splashed waste concrete is blocked inside the crushing box 2.

[0027] A reset mechanism 7 is arranged on the outside of the feed pipe 3. When concrete is filled into the crushing box 2 through the feed pipe 3, the concrete pushes the baffle 4 to swing upward, and the baffle 4 can be pulled to reset by the reset mechanism 7. The reset mechanism 7 includes an arc-shaped pull ring 701, one end of the arc-shaped pull ring 701 is fixedly connected to one end of the support rod 6 located outside the feed pipe 3, and the other end of the arc-shaped pull ring 701 is fixedly connected to a connecting rod 702. The arc-shaped pull ring 701 is semicircular, which is convenient for the arc-shaped pull ring 701 to change its angle around the support rod 6. The arc-shaped pull ring 701 can be converted to a larger angle through the connection rod 702. A base 703 is fixedly connected to one side of the feed pipe 3, and a positioning plate 704 is slidably connected to the inner wall of the base 703. A pull rod 705 is fixedly connected to one side of the positioning plate 704. The pull rod 705 One end located outside the base 703 is movably connected to the other end of the connecting rod 702 at a fixed point. The base 703 has stability by being connected to the feed pipe 3. The moving distance of the pull rod 705 is limited by the positioning plate 704. A spring 706 is sleeved on the outside of the pull rod 705. One end of the spring 706 is fixedly connected to the inner top wall of the base 703, and the other end of the spring 706 is fixedly connected to one side of the positioning plate 704. When the pull rod 705 drives the positioning plate 704 to move, the positioning plate 704 compresses the spring 706. After the external power is lost, the spring 706 pushes the positioning plate 704 to move backward, and at the same time drives the pull rod 705 to move. The pull rod 705 drives the arc pull ring 701 to move backward through the connecting rod 702, and the arc pull ring 701 drives the support rod 6 to reset, so that the support rod 6 drives the baffle 4 to reset.

[0028] A water tank 9 is arranged above the frame 1, and a water pump 10 is fixedly installed inside the water tank 9. The water outlet end of the water pump 10 is fixedly connected to a water pipe 11. When the crushing roller 5 squeezes the waste concrete, a large amount of dust will be generated, and the dust will drift to the outside and pollute the air. The water tank 9 can store water, and the water in the water tank 9 is pumped out by the water pump 10 and transported to the nozzle 12 through the water pipe 11. The top of the crushing box 2 is fixedly connected with the nozzle 12, and one end of the nozzle 12 is located outside the crushing box 2 and is fixedly connected to the other end of the water pipe 11. The water transported to the nozzle 12 by the water pipe 11 can be squeezed and diffused by the nozzle 12, and can be evenly sprayed on the waste concrete, so as to achieve the effect of degrading dust.

[0029] Working principle: When in use, first put the waste concrete into the feed pipe 3, then the waste concrete slides down and contacts the baffle 4, the waste concrete pushes the baffle 4 to swing upward, and while the baffle 4 swings, it drives the arc pull ring 701 to move, the arc pull ring 701 drives the connecting rod 702 to move, the connecting rod 702 drives the pull rod 705 to move, the positioning plate 704 compresses the spring 706 under the drive of the pull rod 705, and then after the waste concrete breaks away from contact with the baffle 4, the spring 706 drives the pull rod 705 to move toward the inside of the base 703 through the positioning plate 704, the pull rod 705 drives the connecting rod 702 to move, and while the connecting rod 702 moves, it drives the arc pull ring 701 to move, the arc tension spring drives the support rod 6 to move, and the support rod 6 drives the baffle 4 to reset.
