Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, and in particular to a sorting device for concrete processing with easily replaceable screens. Background Technology
[0002] Concrete sorting equipment is a key technological tool in the construction and decoration waste treatment system. It is mainly used for the efficient separation, crushing, and resource utilization of inorganic materials such as concrete blocks and bricks in mixed waste. Its application not only reduces the occupation of land resources and environmental pollution caused by traditional landfill methods, but also achieves resource recycling, resulting in significant environmental and economic benefits.
[0003] Most existing concrete sorting devices use bolts to fix the screens to the sorting equipment. However, when it is necessary to replace the screens, the bolts on the screens need to be removed one by one. However, the distance between the screens on most sorting devices is relatively close, which makes it extremely inconvenient to remove the bolts, thereby reducing the efficiency of screen replacement. Utility Model Content
[0004] To at least partially solve the above-mentioned technical problems, this utility model provides a concrete processing sorting device with an easily replaceable screen.
[0005] This utility model is achieved by the following technical solution: a concrete processing sorting device with easy-to-replace screen, including a fixed frame, a replacement component provided on the inner wall of the fixed frame, a filter screen one and a filter screen two fixedly connected to the top of the replacement component, a discharge pipe one and a discharge pipe two fixedly connected to the left end of the fixed frame, a support foot fixedly connected to the bottom of the fixed frame, and a vibration motor fixedly connected to the bottom of the fixed frame.
[0006] The replacement component includes a fixing block. The inner wall of the fixing block has a sliding groove 1, and the two ends of the inner wall of the fixing block have sliding grooves 2. The inner wall of the sliding groove 2 is fixedly connected to a spring 1. The end of the spring 1 away from the sliding groove 2 is fixedly connected to a fixing post. The end of the fixing post away from the spring 1 is fixedly connected to a limit block 1. The bottom of the limit block 1 is fixedly connected to a limit block 2. The bottom of the sliding groove 1 is fixedly connected to a spring 2. The end of the spring 2 away from the sliding groove 1 is fixedly connected to a sliding plate. The inner wall of the sliding groove 1 is slidably connected to a limit post. The inner wall of the limit post has a limit groove 1, and the inner wall of the limit groove 1 has a limit groove 2.
[0007] Through the above technical solution, the spring extends, thereby pushing the limiting block into the limiting groove, and thus fixing the limiting post in the fixing block.
[0008] As a further improvement to the above scheme, the number of springs is set to two, and the two springs are symmetrically distributed around the fixed block.
[0009] Through the above technical solution, the limiting block 2 enters the limiting groove 2, thereby preventing the limiting column from rotating under the oscillation of the oscillating motor, and then the limiting column oscillates out from the inner wall of the fixed block.
[0010] As a further improvement to the above solution, the surface of the fixed column is slidably connected to the inner wall of the sliding groove.
[0011] The above technical solution compresses the second spring by pushing the sliding plate with the limiting post. When the limiting post is pulled out, the second spring extends and pushes the limiting post out of the fixed block through the sliding plate, thus saving effort and making it easier to pull the limiting post out of the fixed block.
[0012] As a further improvement to the above solution, the surface of the limiting block one is slidably connected to the inner wall of the limiting groove one.
[0013] As a further improvement to the above solution, the surface of the second limiting block is slidably connected to the inner wall of the second limiting groove.
[0014] As a further improvement to the above solution, the surface of the sliding plate is slidably connected to the inner wall of the sliding groove.
[0015] As a further improvement to the above solution, the surface of the limiting post is slidably connected to the inner wall of the fixing frame.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model, through the setting of a replacement component, specifically involves pressing the limiting post to cause the limiting block one to slide out from the inside of the limiting groove one. Then, the limiting post is rotated 90 degrees to pull it out from the inside of the fixing block. Subsequently, the filter screen is removed from the inside of the fixing frame, and the replaced filter screen is placed into the fixing frame, so that the sliding groove one corresponds to the hole for the upper limiting post to slide in the fixing frame. The limiting post is inserted into the fixing block through the hole on the fixing frame, causing the limiting block one to push the fixing post, which compresses the spring one until the limiting block two is in a horizontal position with the limiting groove one. The spring one extends and pushes the limiting block one into the limiting groove one, so that the limiting block two also enters the limiting groove two, thereby fixing the filter screen in the fixing frame, thus facilitating quick screen replacement and improving screen replacement efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example:
[0027] Please combine Figure 1-5 This embodiment of a concrete processing sorting device with easily replaceable screens includes a fixed frame 1, a replacement component 2 is provided on the inner wall of the fixed frame 1, a filter screen 3 and a filter screen 4 are fixedly connected to the top of the replacement component 2, a discharge pipe 5 and a discharge pipe 6 are fixedly connected to the left end of the fixed frame 1, a support foot 7 is fixedly connected to the bottom of the fixed frame 1, and a vibration motor 8 is fixedly connected to the bottom of the fixed frame 1.
[0028] Replacement component 2 includes a fixing block 201. The inner wall of the fixing block 201 has a sliding groove 202. The two ends of the inner wall of the fixing block 201 have sliding grooves 203. The inner wall of the sliding groove 203 is fixedly connected to a spring 204. The end of the spring 204 away from the sliding groove 203 is fixedly connected to a fixing post 205. The end of the fixing post 205 away from the spring 204 is fixedly connected to a limiting block 206. The bottom of the limiting block 206 is fixedly connected to a limiting block 207. The bottom of the sliding groove 202 is fixedly connected to a spring 208. The end of the spring 208 away from the sliding groove 202 is fixedly connected to a sliding plate 209. The inner wall of the sliding groove 202 is slidably connected to a limiting post 210. The inner wall of the limiting post 210 has a limiting groove 211. The inner wall of the limiting groove 211 has a limiting groove 212.
[0029] Two springs 204 are provided, symmetrically distributed around the fixing block 201. The surface of the fixing post 205 is slidably connected to the inner wall of the sliding groove 203. The surface of the limiting block 206 is slidably connected to the inner wall of the limiting groove 211. The surface of the limiting block 207 is slidably connected to the inner wall of the limiting groove 212. The surface of the sliding plate 209 is slidably connected to the inner wall of the sliding groove 202. The surface of the limiting post 210 is slidably connected to the inner wall of the fixing frame 1.
[0030] The implementation principle of a concrete sorting device with easily replaceable screens in this application embodiment is as follows: When using this concrete sorting device, first connect the vibrating motor 8 to the external power supply, then start the vibrating motor 8 to make the filter screen 3 and filter screen 4 on the fixed frame 1 vibrate. Then, place the concrete on the filter screen 3 and screen it under the vibration of the vibrating motor 8. The concrete then falls onto the filter screen 4 and is screened again by the filter screen 4 before falling onto the fixed frame 1. Since the fixed frame 1 is inclined, the unscreened concrete slides along the surface of the filter screen 3 and filter screen 4 into the discharge pipe 5 and discharge pipe 6, and the screened concrete in the fixed frame 1 slides out along the slope, thus completing the concrete sorting. When it is necessary to replace the filter screen 3 and filter screen 4, first press the limiting post 210, and the sliding plate 209 pushes the spring 208 to compress, so that the limiting post 210 is replaced. Block 1 206 slides out from inside the limiting groove 211. Then, the limiting post 210 is rotated 90 degrees and pulled out from inside the fixing block 201. Then, the filter screen is removed from inside the fixing frame 1. Then, the replaced filter screen is placed into the fixing frame 1, so that the sliding groove 202 corresponds to the hole through which the limiting post 210 slides in the fixing frame 1. Then, the limiting post 210 is inserted into the fixing block 201 through the hole on the fixing frame 1, so that the limiting block 206 pushes the fixing post 205, causing the spring 204 to compress. When the limiting block 207 and the limiting groove 211 are in a horizontal position, the spring 204 extends and pushes the limiting block 206 into the limiting groove 211, so that the limiting block 207 also enters the limiting groove 212, thereby fixing the filter screen in the fixing frame 1, which facilitates quick replacement of the screen and improves the screen replacement efficiency.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
