Description

Technical Field

[0001] This utility model belongs to the field of construction waste recycling technology, and in particular relates to a construction waste recycling and processing feeding device. Background Technology

[0002] Construction waste refers to building debris generated during urban construction. For example, during urban redevelopment, many buildings need to be demolished and replanned, resulting in a large amount of construction waste. The harmless treatment of construction waste is crucial for environmental and resource conservation.

[0003] Specifically, construction waste accounts for a large proportion of total urban waste. Directly discarding or disposing of construction waste not only leads to increased resource waste and environmental pollution but also incurs excessive processing costs. Therefore, in practice, construction waste is recycled. Recycling construction waste not only saves resources and reduces urban construction costs but also significantly lowers environmental treatment costs.

[0004] As the client, our company is involved in the construction of a commercial street building. During the research on construction waste disposal, the client and supervisors determined that the construction waste, after sorting to identify recyclable building materials, undergoes further processing such as crushing and washing before being recycled. The resulting building materials need to be transferred and fed between different processing equipment. Currently, this is done using belt conveyors to transfer materials from one process to the next. The current method involves installing hoppers on the belt conveyor frame; the building materials enter the conveyor through the discharge port of the processing equipment. However, in actual operation, the fixed distance between the hopper and the belt causes excessively fast feeding, especially when feeding highly pulverized materials. This results in a large amount of dust generated by the powder impacting the belt. Conversely, when feeding larger materials such as stones, the insufficient distance between the hopper and the belt causes the stones to accumulate and become stuck between the hopper and the belt.

[0005] The invention disclosed in application number 202411836759.3 is a recyclable material collection, conveying, and processing device. This device includes a main frame, a processing compartment mounted on the main frame, and electrically controlled tracks mounted on both sides of the main frame. The device loads waste by shoveling it off the ground and guiding it into the processing compartment for processing, followed by storage. While convenient for storage and transportation, the overall structure is overly complex, making it susceptible to malfunctions due to the presence of waste, and it is not suitable for conveying and processing waste of varying sizes.

[0006] Therefore, based on the problems that have occurred in the above-mentioned actual situation, and the existing waste conveying or feeding devices, if the distance between the hopper and the belt can be adjusted according to the particle size of the material during the actual processing, the feeding efficiency of the belt conveyor can be significantly improved, such as reducing dust and avoiding material jamming. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a construction waste recycling and processing feeding device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A construction waste recycling and processing feeding device includes a belt conveyor, which includes a frame and a transmission belt. A feeding hopper structure with an adjustable height is installed at the feeding end of the transmission belt, and the feeding speed of the feeding hopper can be adjusted by adjusting the height.

[0010] The hopper structure includes a hopper and a hoisting motor for lifting the hopper;

[0011] The output shaft of the lifting motor is equipped with a rope reel, and the top of the hopper is fixedly connected to a lifting rope structure, which is wound around the rope reel.

[0012] The frame is equipped with baffles on both sides that block the side wall of the conveyor belt;

[0013] Several fixed support seats are fixedly connected to the inner side wall of the baffle. The fixed support seats are provided with sliding openings. The bottom of the hopper is fixedly connected to a sliding column that is limited and slides within the sliding opening.

[0014] Preferably, the belt conveyor further includes belt drums rotatably connected to the left and right ends of the frame, and the transmission belt drives the belt drums;

[0015] A motor that drives the belt drum to rotate is installed on one side of the belt drum, and the motor is fixedly mounted on the frame.

[0016] Preferably, a pair of fixed brackets that abut against the left and right sidewalls of the hopper are fixedly connected to the inner sidewall of the baffle.

[0017] During the lifting and lowering process of the hopper, the limit sliding is between the fixed support seats.

[0018] Preferably, a U-shaped support frame is fixedly connected to the frame, and the lifting motor is fixedly installed on the support frame.

[0019] Preferably, the suspension rope structure comprises a single strand of rope wound on a rope reel;

[0020] The bottom of the single-strand rope is fixedly connected to four diagonal pull ropes, which are respectively fixed at the four corner positions of the top of the hopper.

[0021] Preferably, a material control and feeding structure is hinged between the baffles.

[0022] Preferably, the material control and feeding structure includes a hinged control plate, one end of which is fixedly connected to a fixed rotating shaft rotatably connected to a baffle, a drive arm is fixedly connected to the fixed rotating shaft, and an electric push rod is hinged to the lower end of the drive arm, the electric push rod being hinged to the outer wall of the baffle.

[0023] Preferably, the bottom of the material control plate is integrally formed with a plurality of comb-tooth structures.

[0024] Preferably, a dust baffle that cooperates with the baffle is installed between the tops of the baffle. The dust baffle includes a horizontal part, and the horizontal part is integrally formed with an inclined part that is inclined downward.

[0025] Preferably, a plurality of support rollers are installed on the frame, and the support rollers are supported on the bottom of the conveyor belt.

[0026] This utility model has the following beneficial effects:

[0027] 1. During the operation, when feeding materials with a high degree of crushing, such as stone powder, the height of the hopper is lowered. This reduces the distance between the hopper and the conveyor belt. The purpose is to prevent the powder from being fed too quickly, as it is easier to feed. (If the distance between the hopper and the belt is too large, the powder will accumulate rapidly and in large quantities on the belt, causing excessively fast feeding.) With the increased distance, the hopper's obstruction ensures that the powder can only continue to be fed after the conveyor belt has carried away the accumulated powder.

[0028] At the same time, reducing the height also has the advantage that: when the height is reduced, the powder falls from a lower height, making it less likely for the powder to generate a large amount of dust, thus protecting the workshop working environment.

[0029] Conversely, during the feeding of stones, due to the poor fluidity of the stones, the height of the feeding hopper is increased to improve the feeding speed and maintain sufficient clearance between the bottom of the feeding hopper and the conveyor belt.

[0030] 2. The material control plate with hinged connection allows for adjustment of the material passing speed by adjusting the distance between the material control plate and the belt. For example, if there is a pile of material on the belt, adjusting the distance between the material control plate and the belt will reduce the material pile. After passing the material control plate, the material pile will be flattened, preventing it from falling into the processing equipment in a piled manner and causing a large amount of dust to escape.

[0031] 3. The device disclosed in this utility model can adjust the feeding onto the conveyor belt according to the condition of the material, that is, ensure that the material on the conveyor belt is fed into the processing equipment in a stable and low dust emission manner, while maintaining a uniform feeding rate of the material and ensuring that the material can be fed into the working equipment smoothly.

[0043] Example 1

[0044] like Figure 1-6 As shown, a construction waste recycling and processing feeding device includes a belt conveyor. The belt conveyor is a conventional belt conveyor disclosed in the prior art. Its main structure includes a frame 13 and a transmission belt 12. Specifically, it is the same as the existing belt conveyor structure. The belt conveyor also includes belt drums 11 rotatably connected to the left and right ends of the frame 13. The transmission belt 12 drives the belt drums 11. A motor 13 that drives the belt drum 11 to rotate is installed on the right belt drum 11. The motor 13 is fixedly mounted on the frame 14.

[0045] Meanwhile, to increase the transmission stability of the conveyor belt 12, similar to existing methods, several support rollers 6 are installed on the frame 14, with the support rollers supporting the bottom of the conveyor belt 12. Roller brackets are rotatably connected to both ends of the support rollers 6, and the roller brackets are fixed to the frame 14.

[0046] During operation, the feeding end (left end) of the belt conveyor is located at the bottom of the discharge port of the processing equipment.

[0047] Meanwhile, a hopper structure with adjustable height is installed at the feeding end of the conveyor belt 12, which can adjust the feeding speed of the hopper.

[0048] Specifically, the hopper structure includes a hopper 41 (shaped as a rectangular hopper portion aligned with the discharge port of the processing equipment, the rectangular hopper portion being integrally formed into a conical hopper portion), and a hoisting motor 42 for hoisting the hopper 41.

[0049] Specifically, the output shaft of the lifting motor 42 is equipped with a rope reel 421, and the top of the hopper 41 is fixedly connected to a lifting rope structure, which is wound around the rope reel 421.

[0050] Specifically, the hoisting rope structure includes a single-strand rope wound on a rope reel 421; the bottom of the single-strand rope is fixedly connected to four inclined ropes 411, which are respectively fixed at the four corner positions of the top of the hopper 41.

[0051] During operation, when the lifting motor 42 drives the rope reel 421 to rotate, the rope reel 421 winds a single strand of rope, while the four inclined pull ropes 411 pull the four corners of the hopper 41 (rectangular hopper), which greatly improves the stability of lifting.

[0052] Meanwhile, a U-shaped support frame 45 is fixedly connected to the frame 14, and the lifting motor 42 is fixedly installed on the support frame (specifically at the bottom of the support frame).

[0053] During operation, to prevent material from spilling from the edge of the conveyor belt 12, baffles 2 are installed on the front and rear sides of the frame 14, respectively, to block the side wall of the conveyor belt 12 (the bottom of the baffles 2 is fixedly installed on the top of the roller bracket by several mounting rods). The inner side of the baffles 2 maintains a safe distance from the edge of the conveyor belt 12.

[0054] Therefore, during operation, the material on the conveyor belt is prevented from being spilled in large quantities by the baffle 2.

[0055] Meanwhile, during the lifting and lowering of the feeding hopper 41, in order to prevent the feeding hopper 41 from shaking, a pair of fixed support seats 44 are fixedly connected to the inner side wall of each of the above baffles 2, and the fixed support seats 44 respectively abut against the left and right side walls of the feeding hopper 41.

[0056] During the lifting and lowering process, the hopper 41 moves up and down along the fixed support base 44 under the limiting position of the fixed support base 44. At the same time, a sliding opening is provided on the fixed support base 44, and the bottom of the hopper 41 is fixedly connected to a sliding column 43 that is limited and slides within the sliding opening (during the lifting and lowering process, the hopper 41 is limited and slides between the fixed support base 44).

[0057] This method further improves the vertical lifting and lowering of the hopper 41 during the lifting process, avoiding swaying.

[0058] During operation, when feeding materials with a high degree of crushing, such as stone powder, the height of the feed hopper 41 is lowered. This reduces the distance between the hopper and the conveyor belt 12. The purpose of this is to prevent the powder from being fed too quickly, as the powder is easier to feed. (If the distance between the hopper and the belt is too large, the powder will accumulate rapidly and in large quantities on the belt in a short time, causing the powder to be fed too quickly.) When the distance is increased, the powder can only be fed after the conveyor belt 12 has continuously carried away the accumulated powder.

[0059] At the same time, reducing the height also has the advantage that: when the height is reduced, the powder falls from a lower height, making it less likely for the powder to generate a large amount of dust, thus protecting the workshop working environment.

[0060] Conversely, during the feeding of stones, due to the poor fluidity of the stones, in order to increase the feeding speed, the height of the feeding hopper 41 is increased to maintain sufficient clearance between the bottom of the feeding hopper 41 and the conveyor belt 12.

[0061] Example 2

[0062] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, in order to control the material feeding speed of the conveyor belt 12 into the working equipment, a material control feeding structure is installed between the baffles 2 by increasing the conveying speed of the conveyor belt 12 and controlling the material conveying speed.

[0063] The material control and feeding structure includes a hinged control plate 53. The material passing speed can be adjusted by adjusting the distance between the control plate 53 and the belt. For example, when there is a pile of material on the belt, the distance between the control plate 53 and the belt is reduced. After the material pile passes through the control plate 53, it is not only flattened, but also prevents the material pile from falling into the processing equipment in a piled manner, causing a large amount of dust to be released.

[0064] Specifically, the front end of the aforementioned material control plate 53 is fixedly connected to a fixed rotating shaft that is rotatably connected to the baffle 2 (the rear end is fixedly connected to a pin, which is hinged to the material control plate 53). A drive arm 52 (fixed to the upper end of the drive arm 52) is fixedly connected to the fixed rotating shaft. An electric push rod 51 is hinged to the lower end of the drive arm 52 (specifically, the pushing end of the electric push rod 51 is fixedly connected to a hinge seat, and the lower end of the drive arm 52 is fixedly connected to a pin, which is hinged to the hinge seat). The electric push rod 51 is hinged to the outer wall of the baffle 2 (an ear seat is fixedly connected to the electric push rod 51, and a pin is hinged to the ear seat, which is fixed to the baffle 2).

[0065] When it is necessary to adjust the distance between the control plate 53 and the transmission belt 12, the electric push rod 51 is turned on, and the drive arm 52 is pushed to flip through the electric push rod. During the flipping process, the drive arm 52 carries the control plate 53 to flip.

[0066] Meanwhile, the bottom of the aforementioned material control plate 53 is integrally formed with several comb-tooth structures 531. The comb-tooth structures 531 (comb-tooth structures are composed of protruding teeth) are used to disperse the material, especially when the piled material touches the comb-tooth structures, it is dispersed.

[0067] Example 3

[0068] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, a dust baffle that cooperates with the baffle 2 is installed between the baffle 2 parts. The dust baffle includes a horizontal part 31, and the horizontal part 31 is integrally formed with an inclined part 32 that is inclined downward.

[0069] Dust baffles are used to further prevent dust from escaping and protect the environment.

[0070] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
