Abstract
Description
Technical Field
[0001] This utility model belongs to the field of construction waste treatment technology, and specifically relates to a construction waste feeding machine. Background Technology
[0002] With the acceleration of urbanization, the amount of waste generated from building demolition has surged, including a large number of discarded concrete components (such as precast beams and columns) containing reinforcing steel bars or metal skeletons. Efficiently separating these metal materials can not only reduce resource waste but also decrease the burden on landfills. However, existing construction waste processing equipment has significant shortcomings in separating long, strip-shaped concrete components (such as concrete poles containing reinforcing steel bars).
[0003] Existing construction waste is directly crushed by crushing equipment, which easily causes rod-shaped metal (steel bars) to twist and entangle, increasing the difficulty of subsequent sorting. In addition, since construction waste is mixed with various materials, some blocky materials that do not need to be crushed will also be crushed, causing additional load on the crushing equipment. Furthermore, the direct accumulation of crushed concrete debris means that subsequent resource utilization (such as aggregate recycling) requires secondary screening, increasing costs. Utility Model Content
[0004] In view of the problems in the related technologies, this utility model proposes a construction waste feeder to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a construction waste feeder, comprising a feeding platform, a long feed roller at one end of the feeding platform, crushing teeth in the middle of the feeding platform, a short feed roller between two adjacent crushing teeth, a mounting side plate at the bottom of the feeding platform, a swaying filter assembly between the mounting side plates, the swaying filter assembly reciprocating along the mounting side plate, and a separating conveyor belt at the far end of the feeding platform, the separating conveyor belt being perpendicular to the feeding platform.
[0007] Furthermore, a feeding platform is provided near the feeding table, which is flush with one end of the long feed roller. Both the long feed roller and the short feed roller have spiral patterns on their surfaces, and the spiral patterns on the surfaces of two adjacent long feed rollers and the short feed roller have opposite spiral directions. The outer diameter of the far end of the long feed roller gradually increases. The long feed roller, the crushing tooth, and the short feed roller are coaxially arranged. A drive assembly is provided at one end of the long feed roller. A spray pipe is provided above the feeding table, and the spray pipe is distributed in the crushing tooth area.
[0008] Furthermore, the drive assembly includes a drive motor, a drive chain, a drive sprocket, and a driven sprocket. The drive motor is located at the bottom of the feeding platform, the drive sprocket is installed at the output end of the drive motor, a rotating shaft is provided through the middle of the long feed roller, and the rotating shaft passes through the side of the feeding table and connects to the driven sprocket. The drive chain connects the drive sprocket and the driven sprocket, and the drive chain is arranged in an up-and-down S-shape to bypass the adjacent driven sprocket. Pressure rollers are provided on both sides above the drive sprocket, and the pressure rollers press down on the drive chain.
[0009] Furthermore, the crushing tooth has an S-shaped structure, the rotating shaft passes through the middle of the S-shaped crushing tooth, one side of the S-shaped arc edge of the crushing tooth rotates in the same direction as the rotating shaft, and a crushing block is provided on the outer side of the end of the S-shaped arc edge of the crushing tooth, and the crushing block protrudes outward.
[0010] Furthermore, the shaking filter assembly includes a shaking screen plate, which is inclined and has a discharge groove at its tail end on one side of the feeding platform. A reciprocating spring is provided on the bottom periphery of the shaking screen plate and is connected to the shaking screen plate. A waste liquid collection box is provided at the bottom of the shaking screen plate.
[0011] Furthermore, a material unloading area is provided on the other side of the separating conveyor belt.
[0012] This utility model has the following beneficial effects: Construction waste is conveyed through a feeding platform. First, the long feed roller at one end of the feeding platform feeds the construction waste, allowing it to enter the range of the crushing teeth and the short feed roller. The crushing teeth crush the concrete on the surface of the long cement rods in the construction waste, causing the rod-shaped metal inside the long cement rods to separate from the concrete. The blocky materials and rod-shaped metal in the construction waste continue to be conveyed forward with the movement of the crushing teeth and the feeding of the short feed roller. After reaching the far end of the feeding platform, the rod-shaped metal crosses the separation conveyor belt and continues to move forward, while the blocky materials cannot cross the separation conveyor belt and fall onto the separation conveyor belt, which is then conveyed to the side, thus separating the blocky materials from the rod-shaped metal. The debris generated during the crushing by the crushing teeth falls directly into the shaking filter assembly between the side plates through the gaps between the crushing teeth. The up-and-down shaking of the shaking filter assembly separates the large and small particles of debris generated during the crushing process.
[0013] Construction waste is placed on the feeding platform located near the feeding station and pushed towards the long feed roller (manually or by other pushing mechanisms). Under the action of the spiral pattern on the surface of the long feed roller, the construction waste moves towards the crushing teeth. Since the spiral patterns on the surfaces of two adjacent long feed rollers are opposite in direction, the construction waste can be stably fed between the two adjacent long feed rollers when the long feed rollers rotate in opposite directions. When the construction waste moves to the position of the crushing teeth, it is crushed. During the crushing process, water is sprayed downwards from the spray pipe above to absorb and remove dust particles generated during the crushing process.
[0014] The crushing teeth have an S-shaped structure. Adjacent crushing teeth rotate in opposite directions, with the S-shaped arc edges of adjacent crushing teeth rotating in opposite directions. This prevents construction waste from being trapped between the S-shaped openings and also prevents non-long cement rod materials from being crushed. Long cement rod waste is located on one side of the S-shaped arc edge. As the crushing teeth rotate, the long cement rod material is first pushed outward. Because the long cement rod is too long, the other part of it is located at the position of the long feed roller or the short feed roller, preventing the long cement rod from rolling to other positions. Therefore, when the long cement rod moves to the position of the crushing block, it is crushed by the crushing block. At this time, other non-long cement rod materials will roll to other positions without being crushed.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0027] Please see Figures 1-6 As shown, this utility model is a construction waste feeder, including a feeding platform 1. A long feed roller 2 is provided at one end of the feeding platform 1. A crushing tooth 3 is provided in the middle of the feeding platform 1. A short feed roller 4 is provided between two adjacent crushing teeth 3. An installation side plate 6 is provided at the bottom of the feeding platform 1. A shaking filter assembly 5 is provided between the installation side plates 6. The shaking filter assembly 5 moves back and forth along the installation side plates 6. A separation conveyor belt 7 is provided at the far end of the feeding platform 1. The separation conveyor belt 7 is perpendicular to the feeding platform 1.
[0028] In operation, construction waste is conveyed through the feeding platform 1. First, the long feed roller 2 at one end of the feeding platform 1 feeds the construction waste, allowing it to enter the range of the crushing teeth 3 and the short feed roller 4. The crushing teeth 3 crush the concrete on the surface of the long cement rods in the construction waste, causing the rod-shaped metal inside the long cement rods to separate from the concrete. The blocky materials and rod-shaped metal in the construction waste continue to be conveyed forward with the movement of the crushing teeth 3 and the feeding of the short feed roller 4. After reaching the far end of the feeding platform 1, the rod-shaped metal crosses the separating conveyor belt 7 and continues to move forward, while the blocky materials cannot cross the separating conveyor belt 7 and fall onto the separating conveyor belt 7, where they are conveyed to the side, thus separating the blocky materials from the rod-shaped metal. The debris generated during the crushing by the crushing teeth 3 falls directly into the shaking filter assembly 5 between the side plates 6 through the gaps between the crushing teeth 3. The up-and-down shaking of the shaking filter assembly 5 separates the particles of different sizes of debris generated during crushing.
[0029] In one embodiment, for the aforementioned feeding platform 1, a feeding platform 11 is provided near the feeding platform 1. The feeding platform 11 is flush with one end of the long feed roller 2. Both the long feed roller 2 and the short feed roller 4 have spiral patterns on their surfaces, and the spiral patterns on the surfaces of two adjacent long feed rollers 2 and short feed rollers 4 have opposite spiral directions. The outer diameter of the long feed roller 2 gradually increases at its distal end. The long feed roller 2, the crushing teeth 3, and the short feed roller 4 are coaxially arranged. A drive assembly 8 is provided at one end of the long feed roller 2. A spray pipe 9 is provided above the feeding platform 1, and the spray pipe 9 is distributed around the crushing teeth. In the tooth 3 area, construction waste is placed on the feeding platform 11 near the feeding table 1 and pushed towards the long feed roller 2 (manually or by setting other pushing mechanisms). Then, under the action of the spiral pattern on the surface of the long feed roller 2, the construction waste moves towards the crushing tooth 3. Since the spiral direction of the spiral pattern on the surface of two adjacent long feed rollers 2 is opposite, the construction waste can be stably fed between the two adjacent long feed rollers 2 when the long feed rollers 2 rotate in opposite directions. When the construction waste moves to the position of the crushing tooth 3, it is crushed. During the crushing, the spray pipe 9 above it sprays water downward to absorb and remove the dust particles generated by the crushing.
[0030] In one embodiment, the drive assembly 8 includes a drive motor 81, a drive chain 82, a drive sprocket 83, and a driven sprocket 84. The drive motor 81 is located at the bottom of the feeding platform 11, the drive sprocket 83 is mounted on the output end of the drive motor 81, a rotating shaft 21 is provided through the middle of the long feed roller 2, and the rotating shaft 21 passes through the side of the feeding table 1 and connects to the driven sprocket 84. The drive chain 82 connects the drive sprocket 83 and the driven sprocket 84, and the drive chain 82 is arranged in an up-and-down S-shape around the adjacent driven sprocket. 84. Pressure rollers 85 are provided on both sides above the drive sprocket 83, and the pressure rollers 85 press down on the drive chain 82. The drive motor 81 in the drive assembly 8 drives the drive sprocket 83 at its output end to rotate. The drive sprocket 83 drives the driven sprocket 84 to rotate through the drive chain 82. Since the drive chain 82 passes around the adjacent driven sprocket 84 in an S-shape, the two adjacent driven sprockets 84 rotate in opposite directions, thereby driving the rotating shaft 21 to rotate in opposite directions, so that the long feed roller 2, the crushing tooth 3 and the short feed roller 4 on the adjacent rotating shaft 21 rotate in opposite directions.
[0031] In one embodiment, the aforementioned crushing tooth 3 has an S-shaped structure. The rotating shaft 21 passes through the middle of the S-shaped crushing tooth 3. One side of the S-shaped arc edge of the crushing tooth 3 rotates in the same direction as the rotating shaft 21, and a crushing block 31 is provided on the outer side of the end of the S-shaped arc edge of the crushing tooth 3, with the crushing block 31 protruding. Through the S-shaped structure of the crushing tooth 3, adjacent crushing teeth 3 rotate in opposite directions, with the S-shaped arc edges of adjacent crushing teeth 3 rotating towards each other, thus preventing construction waste from being trapped. Between the S-shaped openings, non-long cement rod materials are also crushed, while long cement rod waste is on one side of the S-shaped arc edge. As the crushing tooth 3 rotates, it first pushes the long cement rod material outward. However, the long cement rod is too long, and its other parts are at the position of the long feed roller 2 or the short feed roller 4, making it impossible for the long cement rod to roll to other positions. Therefore, when the long cement rod moves to the position of the crushing block 31, it is crushed by the crushing block 31. At this time, other non-long cement rod materials will roll to other positions without being crushed.
[0032] In one embodiment, the aforementioned shaking filter assembly 5 includes a shaking screen plate 51, which is inclined. A discharge trough 52 is located at the tail of the shaking screen plate 51 on one side of the feeding platform 1. A reciprocating spring 53 is provided around the bottom of the shaking screen plate 51 and is connected to it. A waste liquid collection box 54 is located at the bottom of the shaking screen plate 51. The shaking screen plate 51 in the shaking filter assembly 5 receives the concrete outside the crushing long cement rod from the crushing teeth 3 above it. When the crushed concrete... After the block falls onto the shaking screen plate 51, it impacts the shaking screen plate 51, causing it to move downwards and compress the reciprocating spring 53. As the impact force decreases, the reciprocating spring 53 releases an upward elastic force, causing the shaking screen plate 51 to bounce upwards, thus allowing the shaking screen plate 51 to shake up and down. When the shaking screen plate 51 shakes up and down, the small debris that falls onto the shaking screen plate 51 and the water sprayed by the spray pipe 9 pass through the shaking screen plate 51 and enter the waste liquid collection box 54 at its bottom. The larger debris rolls towards the discharge trough 52 along with the tilted shaking screen plate 51 and is discharged from the discharge trough 52.
[0033] In one embodiment, for the aforementioned separating conveyor belt 7, a discharge area is provided on the other side of the separating conveyor belt 7; the separating conveyor belt 7 separates the block material from the crushed rod-shaped metal, the separating conveyor belt 7 carries away the block material, and the rod-shaped metal falls into the discharge area after crossing the separating conveyor belt 7.
