Description

Technical Field

[0001] This invention discloses an anti-jamming crusher for construction waste, which relates to the field of construction waste treatment technology. Background Technology

[0002] Construction waste refers to solid waste generated during the construction, renovation, expansion, or demolition of buildings. This waste can include soil, slag, loose mortar and concrete, brick and concrete fragments from chiseling, and reinforced concrete cut from piling. Improper handling of this waste can have environmental and health consequences; therefore, appropriate measures must be taken for its disposal.

[0003] Currently, the common method for handling construction waste is to use crushing equipment to process it. Most of the waste can be recycled after being crushed, thereby achieving the goal of protecting the environment and saving resources. However, most existing construction waste crushing equipment uses conveyor belts to transport construction waste to the inlet of the crusher. However, due to the different material properties and sizes of the waste, if too much waste accumulates in a certain place on the conveyor belt, it can easily block the inlet of the crusher when it is transported to the crusher, affecting the subsequent crushing process. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, an anti-jamming crusher for construction waste is provided.

[0005] The technical solution is: a construction waste anti-jamming crusher, including a frame, a crusher body for crushing waste, a buffer mechanism for facilitating pre-processing of waste by workers, and a clearing component for clearing waste accumulated at the inlet of the crusher body; the buffer mechanism includes: a bearing plate rotatably connected to the frame for placing waste; a surrounding frame arranged around the top of the frame, with its inner sidewall slidingly contacting the bearing plate and surrounding the bearing plate; a C-shaped guide frame fitted to the surrounding frame and located above the inlet of the crusher body; and a hydraulic cylinder installed at the bottom of the frame for providing power to dump waste onto the bearing plate; the clearing component includes: a clearing frame for pushing waste downwards at the inlet of the crusher body; and an electric push rod installed on the surrounding frame near the end of the crusher body for driving the clearing frame.

[0006] Furthermore, the buffer mechanism also includes: a slider rotatably mounted on the top of the cylinder output shaft; and a guide rail disposed at the bottom of the support plate and capable of cooperating with the slider; when the cylinder is lifted, the slider can slide along the guide rail, while the support plate slowly rotates upward around its connection with the frame.

[0007] Furthermore, the opening of the C-shaped guide frame is consistent with the inlet specification of the crusher body; the opening of the C-shaped guide frame faces the bearing plate, and the two sides of the opening expand outward, which can guide the waste on the bearing plate into the crusher body.

[0008] Furthermore, the unblocking frame extends through both the C-shaped guide frame and the frame surrounding the inlet of the crusher body, enabling it to unblock waste in layers. The unblocking frame is equipped with multiple inclined round rods, which contact the waste to enhance its unblocking ability.

[0009] Furthermore, the enclosure is provided with a blocking component that can limit the amount of waste dumped. The blocking component includes: a baffle that is slidably connected to the enclosure and can block the waste on the support plate; crossbars that are symmetrically arranged on both sides of the baffle and can rise and fall synchronously with the baffle; and lifting rods that are arranged on both sides of the support plate where they are rotatably connected to the frame and can cooperate with the nearest crossbar.

[0010] Furthermore, the frame is provided with an adsorption assembly capable of absorbing ferromagnetic metal from the waste on the support plate. The adsorption assembly includes: a conveyor belt for conveying the ferromagnetic metal; a magnetic suction plate capable of absorbing the ferromagnetic metal from the waste; and a guide hopper disposed on the outer side of the frame near the output end of the conveyor belt for guiding the output ferromagnetic metal outward.

[0011] Furthermore, multiple partitions are evenly spaced on the conveyor belt. When the magnetic plate attracts the ferromagnetic metal, the partitions can scrape the ferromagnetic metal as the conveyor belt rotates. The magnetic plate is located near the input end of the conveyor belt. When the ferromagnetic metal is transported to the output end of the conveyor belt, the magnetic force on the ferromagnetic metal is less than its own weight.

[0012] Furthermore, the frame is provided with extrusion components on both sides, which can initially crush the waste on the support plate and gather it towards the center. The extrusion components include: extrusion plates symmetrically slidably disposed on both sides of the frame, which can crush the waste; a servo motor for driving the extrusion plates; and a cam that can rotate synchronously with the output shaft of the servo motor and push the extrusion plates to reciprocate.

[0013] Furthermore, the extrusion plate is divided into a driving part and a pressing part; the driving part is configured as a spiral frame, and when the cam rotates, its tip will contact and push the two rods on both sides of the spiral frame in sequence; the pressing part is a square plate with uniformly opened serrated protrusions, and the two extrusion plates can cooperate to perform preliminary crushing of waste.

[0014] Furthermore, the frame is provided with a drying assembly capable of drying the waste on the support plate. The drying assembly includes: a mounting frame spanning both sides of the frame; and a dryer disposed on the top of the mounting frame for reducing the moisture content of the waste.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention, through the setting of buffer mechanism and unblocking component, first conveys the waste to the bearing plate and blocks it with the frame to prevent the waste from spilling. It is then manually broken up. Afterwards, the bearing plate is lifted by the cooperation of oil cylinder, guide rail and slider, so that the waste slides slowly and evenly into the crusher body. This can avoid the situation where the crusher body inlet is blocked due to excessive material feeding. In addition, the unblocking frame is driven by electric push rod to reciprocate, which can also push the waste down into the crusher body, further ensuring that the waste can pass smoothly through the crusher body inlet. 2. By setting up the blocking component, when the bearing plate is lifted, the lifting rod will press the crossbar to rise, and at the same time drive the baffle to rise, so that the gap between the baffle and the bearing plate will slowly open, allowing the waste to slowly and orderly slide into the crusher body from the gap during this process, avoiding the situation where a large amount of waste slides into the crusher body. 3. By setting up the adsorption component and the extrusion component, the cam is driven to rotate by the servo motor and push the extrusion plate to reciprocate, which initially crushes the waste on the support plate and gathers the waste towards the middle of the support plate for easy dumping later. The magnetic suction plate can also pick up ferromagnetic metals such as steel bars in the waste and transport them outward by the conveyor belt. 4. By setting up the drying components, the waste material can be dried using a dryer, reducing its moisture content and preventing it from sticking together and agglomerating during crushing if the moisture content is too high, thus affecting the operation of the crushing wheels inside the crusher.

Detailed Implementation

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] Before describing the embodiments in detail, it should be understood that the embodiments are not limited to specific embodiments and can be implemented or carried out in various ways.

[0029] Example 1: An anti-jamming crusher for construction waste, please refer to [link / reference]. Figures 1-4 It includes: a frame 1, which supports other components of the device; a crusher body 2, which crushes waste materials; a buffer mechanism 3, which facilitates pre-treatment of waste materials by workers and prevents waste materials from being directly fed into the crusher body 2 and causing blockages; and a dredging component 4, which can dredge the waste materials accumulated at the inlet of the crusher body 2. The aforementioned buffer mechanism 3 includes: a bearing plate 32, the front end of which is rotatably connected to the frame 1 via a pivot, capable of temporarily holding construction waste; a surrounding frame 31, which is bolted to the top of the frame 1 and surrounds the bearing plate 32 inside, forming a box shape together with the bearing plate 32, and the bearing plate 32 can slide against the inner wall of the surrounding frame 31; and a C-shaped guide frame 33, which is set against the inner front wall of the surrounding frame 31, and the opening of the C-shaped guide frame 33 is consistent with the inlet specification of the crusher body 2, and its opening faces backward and expands to the left and right sides, so that when the bearing plate 32 dumps waste, it can be used to temporarily hold construction waste. The waste material is guided to the inlet of the crusher body 2; the hydraulic cylinder 34 is installed at the bottom of the frame 1 and can lift the bearing plate 32 upward, causing it to tilt, so that the waste material can slide into the crusher body 2 along the inclined surface; the guide rail 35 is installed at the bottom of the bearing plate 32 by bolts; the slider 36 is rotatably connected to the output shaft of the hydraulic cylinder 34 and can slide on the guide rail 35. When the output shaft of the hydraulic cylinder 34 rises, it will lift the bearing plate 32, causing it to rotate counterclockwise around the front pivot. At the same time, the slider 36 will slide on the guide rail 35 to ensure the stability of the lifting process of the bearing plate 32.

[0030] The aforementioned unblocking component 4 includes: an unblocking frame 42, which is slidably installed on the front side of the enclosure 31. Six round rods are arranged in two layers on the frame 42, with all six round rods angled downwards and backwards. The three higher round rods slide through the enclosure 31 and the C-shaped guide frame 33, while the three lower round rods slide through the frame surrounding the inlet of the crusher body 2. This allows for layered and multi-point contact with the waste material, resulting in better unblocking effect. An electric push rod 41 is connected to the unblocking frame 42. Through the continuous extension and retraction of the electric push rod 41, the unblocking frame 42 can be driven to reciprocate and unblock the waste material at the inlet of the crusher body 2.

[0031] Please see Figure 1 , Figure 5 and Figure 6 The frame 31 is equipped with a blocking component 5 that can limit the amount of waste dumping. The blocking component 5 includes: a baffle 51, which is slidably disposed at the front of the frame 31 and has the same width as the bearing plate 32, and can block the waste on the bearing plate 32; two crossbars 52, which are symmetrically disposed on the left and right sides of the baffle 51 in an embedded manner; and two lifting rods 53, which are also fixedly disposed at the left and right ends of the pivot connecting the bearing plate 32 and the frame 1. When the bearing plate 32 rotates, the lifting rods 53 will rotate counterclockwise and contact the corresponding crossbars 52 and lift them up, and the baffle 51 will also be lifted up.

[0032] After the construction waste is dumped onto the support plate 32, it can be manually shoveled onto the support plate 32 to distribute the waste evenly. Simultaneously, some difficult-to-crush metal or other waste materials can be picked out. Then, the hydraulic cylinder 34 is activated to lift the support plate 32, causing it to rotate counterclockwise to an inclined position. With the cooperation of the guide rail 35 and the slider 36, it can rotate smoothly. At the same time, the lifting rod 53 also rotates, lifting the crossbar 52 upwards. The baffle 51 also rises slowly. During the ascent of the baffle 51, the waste will slowly slide along the inclined support plate 32 and... The gap between the baffle 51 and the bearing plate 32 enters the crusher body 2, which can limit the amount of waste fed in, and prevent too much waste from sliding down at the same time, which could cause the inlet of the crusher body 2 to be blocked. At the same time, the outward expansion of the C-shaped guide frame 33 can also guide the sliding of waste, so that the waste enters from the center of the inlet of the crusher body 2. The operator can also start the electric push rod 41 to drive the unblocking frame 42 to reciprocate, pushing the waste at the inlet of the crusher body 2, further preventing blockage. After the waste enters the crusher body 2, it will be crushed by the crushing wheel inside.

[0033] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 7 and Figure 8 An adsorption assembly 6 is provided on the frame 31 to attract ferromagnetic metals from the waste on the support plate 32. The adsorption assembly 6 includes: a conveyor belt 61, which is installed at the top center of the frame 31 and can transport ferromagnetic metals from the waste. Multiple partitions are evenly spaced on the conveyor belt 61; a magnetic suction plate 62, which is installed inside the conveyor belt 61 above the support plate 32 and can attract ferromagnetic metals from the waste. When the metal is transported to the left end of the conveyor belt 61, the magnetic attraction force on the ferromagnetic metal is less than its own weight, so it falls down; and a guide hopper 63, which is bolted to the left side of the frame 31 and located directly below the output end of the conveyor belt 61, and can guide the falling metal.

[0034] As the waste slides forward along the support plate 32, it passes the magnetic suction plate 62. Some of the ferromagnetic metal contained therein will be attracted upward and adhered to the conveyor belt 61. When the conveyor belt 61 is running, the partitions on it will scrape the metal and move it along the conveying direction of the conveyor belt 61. When it reaches the left end of the conveyor belt 61, the attraction of the magnetic suction plate 62 weakens, and the metal will fall onto the guide hopper 63 and be discharged outward from the guide hopper 63.

[0035] Please see Figure 1 and Figure 9The frame 31 has extrusion components 7 on both sides, which can initially crush the waste on the support plate 32 and gather it to the center. The extrusion components 7 include: extrusion plates 73, which are symmetrically slidably arranged on both sides of the frame 31 and are divided into a driving part and a pressing part. The driving part is a U-shaped frame, and the pressing part is a square plate with uniformly serrated protrusions. The two extrusion plates 73 work together to initially crush the waste and gather it to the center of the support plate 32; and servo motors 71, of which two are also provided, which can power the extrusion plates. The reciprocating motion of 73 provides power; cam 72 is fixedly mounted on the output shaft of servo motor 71 and located in the drive part of extrusion plate 73. After servo motor 71 is started, cam 72 will rotate, and its tip will contact the left and right sides of the loop frame part of extrusion plate 73 in sequence and push it, so that extrusion plate 73 slides back and forth on frame 31. When the two extrusion plates 73 approach each other, they will impact the waste, thereby achieving the initial crushing of waste, and at the same time gathering the waste in the middle of bearing plate 32.

[0036] Please see Figure 1 and Figure 10 A drying assembly 8 is provided on the frame 31 to dry the waste on the support plate 32. The drying assembly 8 includes: a mounting frame 81, which is installed on the frame 31 by bolts; and a dryer 82, which is located on top of the mounting frame 81 and directly above the support plate 32. Before the waste is fed into the crusher body 2, the worker can start the dryer 82 to dry the waste, so as to reduce the moisture content of the waste and prevent the waste from sticking together in the crusher body 2 due to excessive moisture, which would affect the normal operation of the crusher body 2.
