[0002] The background technology of construction site waste pretreatment devices mainly involves the recycling, sorting, and treatment of construction waste, aiming to reduce the environmental impact of construction waste and achieve resource reuse. Construction site waste mainly includes various materials such as concrete, steel bars, wood, bricks, plastics, and glass. If these wastes are directly landfilled or incinerated without treatment, they will cause serious environmental pollution. With increasingly stringent environmental regulations and the promotion of sustainable development concepts, the rational recycling and reuse of construction waste has gradually become a focus of the construction industry.

The front surface of the treatment tank has a window, and a door is hinged to the left edge of the window. The door and the window are exactly the same size and shape. A steam generator is welded to the left side wall of the treatment tank. A booster pump is fixedly installed on the upper surface of the treatment tank, and a pressure gauge is connected to the upper surface of the treatment tank. A drain pipe is connected to the right side of the treatment tank, and a second butterfly valve is connected to the middle of the drain pipe. This patent is safe and practical, solves the problem of waste accumulation, and avoids the adverse effects of bacteria and odors generated by long-term waste accumulation on the physical and mental health of workers on the construction site.

[0004] However, the current waste pretreatment devices used on construction sites have the following problems: when workers put in too much waste or pile it up excessively, the crushing components are easily jammed by large clumps of waste, causing the crushing efficiency of the device to drop, or even causing it to shut down. Therefore, we have proposed a waste pretreatment device for construction sites. Utility Model Content

[0005] The purpose of this utility model is to provide a waste pretreatment device for construction sites, which can solve the problem in related technologies that when workers put in too much waste or it is piled up excessively, the crushing component is easily jammed by large clumps of waste, causing the crushing efficiency of the device to decrease or even stop.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A waste pretreatment device for construction sites includes a main chamber, a crushing chamber fixedly connected to the bottom of the main chamber, a base plate fixedly connected to the bottom of the crushing chamber, a crushing assembly disposed at the bottom of the base plate, and a dispersing device disposed at the top of the main chamber. The dispersing device includes a feeding frame, the bottom of which is fixedly connected to the top of the main chamber, a motor support plate fixedly connected to the top of the feeding frame, a driving assembly disposed at the top of the motor support plate, an extension rod fixedly connected to the driving end of the driving assembly, and a dispersing plate fixedly connected to the side of the extension rod away from the driving end of the driving assembly.

[0008] Preferably, the drive assembly includes a drive motor, the bottom of which is fixedly connected to the top of the motor support plate, the output shaft of which is fixedly connected to a main rotating shaft, an outward connecting ring fixedly connected to the outer wall of the main rotating shaft, and the side of the extension rod away from the disintegrating connecting plate is fixedly connected to the outer wall of the outward connecting ring, wherein the outward connecting ring is provided at the drive end of the drive assembly.

[0009] Preferably, the crushing assembly includes a crushing motor, the top of which is fixedly connected to the bottom of the base plate, the output shaft of which is fixedly connected to a crushing roller, and the bottom of the base plate is fixedly connected to a shock-absorbing and stabilizing frame.

[0010] Preferably, the outer wall of the disintegrating connecting plate is arc-shaped, and the material of the disintegrating connecting plate is a high-toughness and high-hardness material.

[0011] Preferably, an anti-snagging device is provided on the inner wall of the main chamber. The anti-snagging device includes a partition plate. The outer wall of the partition plate is fixedly connected to the inner wall of the main chamber. A linkage rotating column is fixedly connected to the bottom of the main rotating shaft. A two-way connecting plate is fixedly connected to the bottom of the linkage rotating column. An inner cavity scraper is fixedly connected to the side of the two-way connecting plate. A bottom cavity scraper is fixedly connected to the side of the inner cavity scraper near the two-way connecting plate.

[0012] Preferably, the side of the inner cavity scraper away from the bidirectional connecting plate is set as an inclined surface, and the bottom of the bottom cavity scraper is set as an inclined conical surface.

[0013] Preferably, the inner cavity scraper is in contact with the inner wall of the crushing chamber on the side closest to the crushing chamber, and the bottom of the bottom cavity scraper is in contact with the top of the bottom plate.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention utilizes a dispersion device to coordinate the feed frame, motor support plate, drive motor, main shaft, outward connecting ring, extension rod, and dispersing plate. The rotation of the outward connecting ring drives the extension rod to rotate, which in turn drives the dispersing plate to rotate. Subsequently, the worker feeds the waste material into the feed frame. When the waste material is fed in, it first comes into contact with the dispersing plate. At this time, due to the rotation of the dispersing plate, it evenly disperses the fed waste material, thereby preventing excessive accumulation of the waste material, which could cause the crushing components to be jammed by large pieces of waste, resulting in a decrease in the crushing efficiency of the device or even causing it to stop completely.

[0016] This invention, through the installation of an anti-snagging device, enables the partition plate, linkage rotating column, bidirectional connecting plate, inner cavity scraper, and bottom cavity scraper to work together. The rotation of the main rotating shaft drives the linkage rotating column to rotate, which in turn drives the bidirectional connecting plate to rotate, which in turn drives the inner cavity scraper to rotate, and the inner cavity scraper to rotate, which in turn drives the bottom cavity scraper to rotate. At this time, the rotation of the inner cavity scraper causes it to scrape the inner wall of the crushing chamber, and the rotation of the bottom cavity scraper causes it to scrape the top surface of the bottom plate. This prevents waste from reacting with the device due to static electricity and adhering to the inner wall of the device. Over time, this would result in excessive waste adhering to the device, leading to a decrease in the device's processing capacity. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a waste pretreatment device for construction sites includes a main chamber 1, a crushing chamber 2 fixedly connected to the bottom of the main chamber 1, a bottom plate 3 fixedly connected to the bottom of the crushing chamber 2, a crushing component 4 disposed at the bottom of the bottom plate 3, and a dispersing device 5 disposed at the top of the main chamber 1. The dispersing device 5 includes a feeding frame 51, the bottom of the feeding frame 51 fixedly connected to the top of the main chamber 1, a motor support plate 52 fixedly connected to the top of the feeding frame 51, a driving component disposed at the top of the motor support plate 52, an extension rod 56 fixedly connected to the driving end of the driving component, and a dispersing plate 57 fixedly connected to the side of the extension rod 56 away from the driving end of the driving component. The extension rod 56 is made of a high-hardness material.

[0026] The drive assembly includes a drive motor 53. The bottom of the drive motor 53 is fixedly connected to the top of the motor support plate 52. The output shaft of the drive motor 53 is fixedly connected to a main rotating shaft 54. An outward connecting ring 55 is fixedly connected to the outer wall of the main rotating shaft 54. The side of the extension rod 56 away from the disintegrating connecting plate 57 is fixedly connected to the outer wall of the outward connecting ring 55. The outward connecting ring 55 is the drive end of the drive assembly. The drive motor 53 is electrically connected to an external controller.

[0027] The crushing assembly 4 includes a crushing motor 41. The top of the crushing motor 41 is fixedly connected to the bottom of the base plate 3. The output shaft of the crushing motor 41 is fixedly connected to a crushing roller 42. The bottom of the base plate 3 is fixedly connected to a shockproof and stabilizing frame 43. This is existing technology and will not be elaborated further.

[0028] The outer wall of the disintegration plate 57 is curved, and the material of the disintegration plate 57 is made of high toughness and high hardness material, which can ensure the long-term use of the disintegration plate 57.

[0029] According to the above structure, when waste processing is required, the worker first puts the waste into the crushing chamber 2. Then, the worker starts the crushing motor 41 through the external controller. The output shaft of the crushing motor 41 rotates, driving the crushing roller 42 to rotate. The rotation of the crushing roller 42 causes the crushing roller 42 to crush the waste in the crushing chamber 2. Before starting the waste crushing work, the worker starts the drive motor 53 through the external controller. The output shaft of the drive motor 53 rotates, driving the main shaft 54 ​​to rotate. The outward connecting ring 55 rotates, which in turn drives the extension rod 56 to rotate. The extension rod 56 then drives the dispersing plate 57 to rotate. Subsequently, the worker puts the waste into the material frame 51. When the waste is put in, it first comes into contact with the dispersing plate 57. At this time, due to the rotation of the dispersing plate 57, the dispersing plate 57 evenly beats and disperses the waste, thereby preventing the waste from piling up excessively and causing the crushing component 4 to be jammed by large pieces of waste, resulting in a decrease in the crushing efficiency of the device, or even jamming and shutdown.

[0030] like Figure 1-5 As shown, an anti-snagging device 6 is provided on the inner wall of the main chamber 1. The anti-snagging device 6 includes a partition plate 61. The outer wall of the partition plate 61 is fixedly connected to the inner wall of the main chamber 1. A linkage rotating column 62 is fixedly connected to the bottom of the main rotating shaft 54. A two-way connecting plate 63 is fixedly connected to the bottom of the linkage rotating column 62. An inner cavity scraper 64 is fixedly connected to the side of the two-way connecting plate 63. A bottom cavity scraper 65 is fixedly connected to the side of the inner cavity scraper 64 near the two-way connecting plate 63. The bottom cavity scraper 65 is made of a highly wear-resistant material.

[0031] The inner cavity scraper 64 is inclined on the side away from the bidirectional connecting plate 63, and the bottom of the bottom cavity scraper 65 is inclined conical. The inclined surface can enhance the cleaning effect of the scraper.

[0032] The inner cavity scraper 64 is in contact with the inner wall of the crushing chamber 2 on the side closest to the crushing chamber 2, and the bottom of the bottom cavity scraper 65 is in contact with the top of the bottom plate 3. The necessary contact can ensure the cleaning effect.

[0033] According to the above structure, the rotation of the main rotating shaft 54 ​​drives the linkage rotating column 62 to rotate, the rotation of the linkage rotating column 62 drives the bidirectional connecting plate 63 to rotate, the rotation of the bidirectional connecting plate 63 drives the inner cavity scraper 64 to rotate, and the rotation of the inner cavity scraper 64 drives the bottom cavity scraper 65 to rotate. At this time, the rotation of the inner cavity scraper 64 causes the inner cavity scraper 64 to scrape the inner wall of the crushing chamber 2, and the rotation of the bottom cavity scraper 65 causes the bottom cavity scraper 65 to scrape the top surface of the bottom plate 3, thereby avoiding the waste material from reacting with the device with static electricity and adhering to the inner wall of the device. Over time, this would cause too much waste material to adhere to the device, resulting in a decrease in the device's processing capacity.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
