Description
Technical Field
[0001] The utility model relates to the technical field of concrete, in particular to a crushing device for recycling concrete waste. Background Art
[0002] With the rapid development of the construction industry, a large amount of concrete waste is generated. The traditional method of treating concrete waste is usually to transport it to a landfill, resulting in a waste of resources and environmental pollution. Among them, the "concrete waste crushing and recycling device" disclosed in the application number "CN218854506U" has solved the problem that when concrete is crushed, the concrete will fall on the filter screen, and the large-size concrete will be blocked and difficult to contact the crushing nails and crushing balls set on the outer wall of the roller again, resulting in the crushing effect of this device being limited. After further searching, it was found that the "recycling device for concrete waste" disclosed in the application number "CN219291569U" has effectively solved the problem of concrete waste in traditional buildings through a specific technical structure setting. After the steel bars in the clot are taken out, there are still large pieces of waste, which is not conducive to transportation and decomposition, so the concrete block needs to be crushed. The crushed concrete particles contain a lot of dust and impurities, and the quality is not high. Technical disadvantages, but in actual use, there are still many defects in the concrete waste recycling crushing device with similar structure, such as: the commonly used concrete waste recycling crushing device, the feed port is in an open state, so that the dust generated during the crushing process is dispersed in the surrounding air, causing the surrounding environment to be polluted, and causing harm to the health of the surrounding personnel. It is not convenient to filter the crushed product, resulting in a large deviation in the particle size of the crushed product, which affects the subsequent use of the crushed product by subsequent personnel. Therefore, it is necessary to design a crushing device for concrete waste recycling. Utility Model Content
[0003] The purpose of the utility model is to provide a crushing device for recycling concrete waste to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crushing device for recycling concrete waste, comprising a base plate, a collecting box is fixedly installed on the top of the base plate, a crushing box is fixedly connected to the top of the collecting box, a mounting box is fixedly installed on one end of the crushing box, a servo motor is fixedly connected to one end of the mounting box, a mounting frame is fixedly installed on the top of the crushing box, an electric push rod is fixedly connected to the bottom of the mounting frame, a sleeve is fixedly installed on the bottom of the electric push rod, a spring is fixedly connected inside the sleeve, a sealing structure is installed on the spring through a slide plate, a first crushing roller is fixedly installed inside the crushing box, a second crushing roller is fixedly installed on one side of the crushing box at the bottom of the first crushing roller, and a control box is fixedly installed on the top of one side of the crushing box.
[0005] When the device is powered on, the user puts waste into the feed port. The waste is squeezed by its own gravity to squeeze the sealing structure, thereby stretching the spring and causing the waste to fall into the crushing box. After all the waste enters the crushing box, the sealing structure moves upward and fits with the feed end under the restoring force of the spring, thus realizing the sealing function of the feed end inside the crushing box, preventing the dust generated after the waste is crushed from dispersing in the surrounding air and causing pollution to the surrounding environment, and reducing the harm to the user's body, thus ensuring the user's health. After the user observes through the visual window that the waste is blocking the feed port, the electric push rod drives the sleeve to move downward. The distance between the sealing structure and the internal feed end of the crushing box is increased so that the blocked waste can fall in, avoiding the waste from being put in too quickly and blocking the feed port, thereby affecting the normal operation of the crushing box and improving the feeding efficiency. The servo motor is operated to rotate the first crushing roller and the second crushing roller. The first crushing roller crushes the incoming waste. After the crushed waste is filtered by the filter, the larger particles of waste fall onto the second crushing roller. The operation of the second crushing roller crushes the larger particles of waste, thereby realizing the function of secondary crushing of the waste, reducing the content of large particles in the crushed product, reducing the particle size deviation of the crushed product, and facilitating the subsequent processing and use of the crushed product.
[0006] Preferably, a shutter is fixedly installed at one end of the installation box between the servo motors, a gear is fixedly installed inside the installation box, and the gear is fixedly connected to the output end of the servo motor. The shutter meets the demand for air flow inside and outside the installation box, slows down the temperature rise speed inside the installation box, and prolongs the service life of internal parts. The gear has the function of transmitting the power of the servo motor, so that the crushing roller rotates at the same frequency, ensuring the stability of the operation of the crushing roller.
[0007] Preferably, a slide rail is fixedly installed inside the collection box, and a drawer is installed between the slide rails through a slider. The drawer has a storage function for the crushed finished products, which is convenient for personnel to centrally handle the finished products and prevent the finished products from being dispersed in the outside air and polluting the surrounding environment. The slide rail is convenient for users to pull the drawer, which improves the efficiency of drawer movement.
[0008] Preferably, a filter is fixedly installed inside the crushing box at the bottom of the first crushing roller, a handle is fixedly connected to the other side of the crushing box, and a visual window is fixedly installed at one end of the feed port. The handle is convenient for users to pull the device, saving physical effort in moving the device, and the visual window is convenient for users to observe the waste entering the feed port, so as to facilitate users to adjust the electric push rod to prevent the feed port from being blocked.
[0009] Preferably, the bottom of the base plate is fixedly connected with supporting feet, and the bottom of the base plate between the supporting feet is fixedly installed with rollers. The supporting feet increase the contact area between the device and the ground, prevent the device from deviating after the movement is completed, and increase the stability of the device. The rollers facilitate personnel to move the device and save work time for moving the device.
[0010] Preferably, a control module is fixedly connected inside the control box, a fan is fixedly connected to one side of the control box, and a dust screen is fixedly installed inside the top of the control box. The control module can regulate the orderly operation of the electrical equipment on the device, thereby improving the operating efficiency of the device. The operation of the fan increases the speed of air flow inside the control box, increasing the cooling rate inside the control box. The dust screen filters the air entering the control box, reducing the accumulation of dust inside the control box.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. Through the cooperation between the electric push rod, spring and sealing structure, the waste is squeezed by its own gravity to squeeze the sealing structure, thereby stretching the spring and causing the waste to fall into the crushing box. After all the waste enters the crushing box, the sealing structure moves upward and fits with the feed end under the action of the spring restoring force, realizing the sealing function of the feed end inside the crushing box, preventing the dust generated after the waste is crushed from dispersing in the surrounding air and causing pollution to the surrounding environment, and reducing the harm to the user's body, thereby ensuring the health of the user. After the waste blocks the feed port, the electric push rod drives the sleeve to move downward to increase the distance between the sealing structure and the feed end inside the crushing box, so that the blocked waste can fall in, avoiding the waste from being put in too quickly to block the feed port, thereby affecting the normal operation of the crushing box and improving the unloading efficiency.
[0013] 2. Through the combination of the servo motor, the first crushing roller and the second crushing roller, the servo motor operates to rotate the first crushing roller and the second crushing roller, the first crushing roller crushes the incoming waste, and after the crushed waste is filtered by the filter, the larger particles of waste fall onto the second crushing roller, and the second crushing roller operates to crush the larger particles of waste, thereby realizing the function of secondary crushing of the waste, reducing the content of large particles in the crushed product, reducing the particle size deviation of the crushed product, and facilitating the subsequent processing and use of the crushed product.

[0023] A shutter 402 is fixedly installed at one end of the installation box 4 between the servo motors 401, a gear 403 is fixedly installed inside the installation box 4, and the gear 403 is fixedly connected to the output end of the servo motor 401, a slide rail 202 is fixedly installed inside the collection box 2, a drawer 201 is installed between the slide rails 202 through a slider, a filter screen 302 is fixedly installed inside the crushing box 3 at the bottom of the first crushing roller 7, a handle 301 is fixedly connected to the other side of the crushing box 3, and a visual window 601 is fixedly installed at one end of the feed port 6.
[0024] The working principle of the crushing device for recycling concrete waste based on Example 1 is as follows: the device is powered on and the user puts waste into the feed port 6. The waste is squeezed by its own gravity to squeeze the sealing structure 10, thereby stretching the spring 1201, so that the waste falls into the crushing box 3. After all the waste enters the crushing box 3, the sealing structure 10 moves upward to fit the feed end under the restoring force of the spring 1201, thereby realizing the function of sealing the feed end inside the crushing box 3, preventing the dust generated after the waste is crushed from dispersing in the surrounding air and causing pollution to the surrounding environment, and reducing the harm to the user's body, thereby ensuring the user's health.
[0025] After the user observes through the visual window 601 that the waste material blocks the feed port 6, the electric push rod 9 drives the sleeve 12 to move downward, increasing the distance between the sealing structure 10 and the feed end inside the crushing box 3, so that the blocked waste material can fall in, thereby preventing the waste material from being put in too quickly to block the feed port 6, thereby affecting the normal operation of the crushing box 3, and improving the material unloading efficiency;

The operation of the second crushing roller 8 crushes the larger particles of waste, thereby realizing the function of secondary crushing of waste, reducing the content of large particles in the crushed product, reducing the particle size deviation of the crushed product, and facilitating the subsequent processing and use of the crushed product;
[0027] The drawer 201 has a storage function for the crushed finished products, which is convenient for personnel to centrally process the finished products. The slide rail 202 is convenient for users to pull the drawer 201, thereby improving the efficiency of moving the drawer 201.
