[0003] When factories crush waste concrete, they usually need to use concrete crushers, also known as jaw crushers, which are suitable for metallurgy, mining, construction, chemical industry, water conservancy and railway departments, and are used for fine and medium crushing of various ores and rocks with compressive strength below 250Mpa. It has the characteristics of large crushing ratio, uniform finished product particle size, low power consumption, and easy maintenance.
[0004] The jaw crusher on the market mainly consists of a body with a feeding port on the top of the body. When working, waste is fed from the feeding port and crushed by the mutual compression of the fixed jaw plate and the movable jaw plate inside the body. However, since the feeding port is an open structure, the dust generated during the crushing process of the waste will float to the outside of the body through the feeding port, which will pollute the surrounding environment. Utility Model Content
[0005] The present application provides a recycled concrete production device, which has the effect of reducing the pollution to the surrounding environment caused by dust generated during the crushing process, and making the crushing process more environmentally friendly.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.
[0024] The embodiment of the present application discloses a recycled concrete production device.
[0025] Reference Figure 1 , Figure 2A recycled concrete production device includes a body 1, and a feeding port 2 for feeding waste into the body 1 is formed on the top of the body 1. A dust curtain 3 for shielding the top of the feeding port 2 is arranged on the outer side wall of the top of the body 1, one side of the dust curtain 3 is fixedly arranged on the outer side wall of the body 1 through a connecting frame, and the other side of the dust curtain 3 is rotatably arranged on the top of the body 1 through the connecting frame. The dust curtain 3 is roughly fan-shaped after unfolding, and the dust curtain 3 is made of waterproof cloth. A mounting frame 4 is also arranged outside the body 1, and a conveyor belt 40 for conveying waste into the feeding port 2 is rotatably arranged on the mounting frame 4, and the conveyor belt 40 is driven by an external motor. The dust curtain 3 in the unfolded state covers the top of the discharge port of the conveyor belt 40, and the length of the conveyor belt 40 is arranged to be inclined downward in the direction away from the feeding port 2.
[0026] like Figure 2 , Figure 3 As shown, a dust baffle 5 is rotatably provided on the top inner wall of the feed port 2, and the rotation axis of the dust baffle 5 extends in the horizontal direction. Under the action of its own gravity, the dust baffle 5 blocks the feed port 2 from the inside of the machine body 1. Two return springs 6 are installed on the side wall of the dust baffle 5 away from the feed port 2, and the return springs 6 are symmetrically arranged on both sides of the dust baffle 5. One end of the return spring 6 is in conflict with the dust baffle 5, and the other end of the return spring 6 is in conflict with the inner wall of the machine body 1. In the natural state, the return spring 6 is used to push the dust baffle 5 to rotate in the direction close to the feed port 2 until the dust baffle 5 blocks the feed port 2.
[0027] The dust baffle 5 can ensure that the dust baffle 5 blocks the feeding port 2 under the elastic force of the return spring 6. When waste is poured from the discharge port of the conveyor belt 40 into the feeding port 2, the dust baffle 5 will compress the return spring 6 under the push of the waste, and the dust baffle 5 will be opened, and the waste can smoothly fall into the body 1. When the conveyor belt 40 stops feeding, the dust baffle 5 will automatically reset under the elastic force of the return spring 6 and block the feeding port 2 again, so as to effectively prevent dust from floating outward from the feeding port 2, further enhancing the dust prevention effect.
[0028] like Figure 1 , Figure 2 As shown, an assembly rack 7 is fixedly mounted on the top outer wall of the machine body 1, and the assembly rack 7 is located on the side of the feeding port 2 away from the mounting rack 4. A plurality of spray pipes 8 with spray ports facing the feeding port 2 below are mounted on the assembly rack 7, and adjacent spray pipes 8 are sequentially arranged at intervals along the length direction of the feeding port 2, and the dust curtain 3 in the unfolded state covers the outside of the assembly rack 7. When the conveyor belt 40 feeds into the feeding port 2, water is passed into each spray pipe 8, and the spray water sprayed from the spray port at the bottom of the spray pipe 8 can effectively suppress the diffusion of dust, thereby further enhancing the dust reduction effect.
[0029] like Figure 1 , Figure 4 As shown, two clamping posts 10 close to the mounting frame 4 are fixedly mounted on the outer side wall of the machine body 1, and the clamping posts 10 are symmetrically arranged on both sides of the machine body 1. The side wall of the mounting frame 4 facing the clamping posts 10 is formed with clamping grooves 42 for mutually clamping with the clamping posts 10 opposite to each other, and the two sides of the mounting frame 4 are clamped on the clamping posts 10 from top to bottom through the clamping grooves 42. Through the mutual clamping cooperation between the clamping posts 10 and the clamping grooves 42, the mounting frame 4 can be fixed on one side of the machine body 1.
[0030] like Figure 1 , Figure 2 As shown, a plurality of mutually parallel material separators 41 are fixedly mounted on the outer surface of the conveyor belt 40, and the length of the material separators 41 extends along the width direction of the conveyor belt 40. Adjacent material separators 41 are arranged in sequence along the length direction of the conveyor belt 40. The material separators 41 can effectively prevent the waste from slipping on the surface of the conveyor belt 40 when the waste is lifted toward the feeding port 2, thereby ensuring that the waste can be smoothly conveyed to the feeding port 2.
[0031] like Figure 1 , Figure 2 As shown, two baffle plates 43 are fixedly mounted on the mounting frame 4, and the baffle plates 43 are symmetrically arranged on both sides of the conveyor belt 40. The baffle plates 43 on both sides are arranged opposite to each other, and the length of the baffle plates 43 extends along the length direction of the upper surface of the conveyor belt 40. The width of the baffle plates 43 exceeds the upper surface of the conveyor belt 40, and the baffle plates 43 on both sides can effectively prevent waste from falling from both sides of the conveyor belt 40, playing a role of blocking materials on both sides of the conveyor belt 40.
[0032] The implementation principle is: the dust curtain 3 is covered above the discharge port of the conveyor belt 40. At this time, the probability of dust spreading to the surrounding environment can be greatly reduced under the blocking of the dust curtain 3, so that a better dust prevention effect can be achieved, and the pollution to the surrounding environment caused by the dust generated during the crushing process can be reduced, and the crushing process is more environmentally friendly. In addition, when the conveyor belt 40 stops feeding, the dust baffle 5 will automatically reset under the elastic force of the reset spring 6, and the feeding port 2 will be blocked again, so as to effectively prevent dust from floating outward from the feeding port 2, further enhancing the dust prevention effect. By passing water into each spray pipe 8, the spray water sprayed from the spray port at the bottom of the spray pipe 8 can effectively suppress the diffusion of dust, thereby further enhancing the dust reduction effect.
[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
