Description

Technical Field

[0001] The utility model relates to the technical field related to the recycling of construction waste, in particular to a construction waste recycling processing system. Background Art

[0002] Construction waste mainly refers to reinforced concrete blocks, bricks and tiles generated by the demolition of houses. After sorting, crushing, screening and other processes, some of the steel can be recovered, and the crushed concrete blocks can also be recycled as raw materials for concrete. That is, construction waste has a high recycling value.

[0003] The existing construction waste recycling and processing system mainly includes sorting, crushing, screening and other tasks. Among them, crushers are mostly used for crushing. The existing crushers are mainly composed of hoppers, crushing hammers, motors, etc. During the crushing process, once the gap between the crushing hammers is too large, the construction waste is often not crushed and falls directly. If the gap between the crushing hammers is too small, the construction waste with a larger diameter cannot be easily crushed, resulting in reduced crushing efficiency. Utility Model Content

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0026] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0027] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0028] See also Figures 1 to 6 In an embodiment of the utility model, a construction waste recycling and processing system includes multiple groups of mechanisms such as sorting, crushing, and screening, wherein the crushing mechanism includes a base 1, a feed chute 22, a support frame 23, a mounting seat 25, a blocking member, a crushing device, a filtering device, a mobile driving member, and a one-way transmission member.

[0029] The details are as follows, including:

[0030] See also Figure 1 , Figure 2 , Figure 4 , a base 1 and a support frame 23 fixedly mounted on the base 1, a material chute 22 is mounted on the support frame 23, and also includes a mounting seat 25 mounted on the base 1, a blocking member for controlling the opening or closing of the material chute 22 is mounted on the mounting seat 25, and also includes a crushing device, the crushing device is mounted on the support frame 23, so as to crush the construction waste dropped from the material chute 22;

[0031] A filtering device, mounted on the base 1;

[0032] The mobile driving member is installed on the base 1, connected to the filtering device, and connected to the crushing device through a one-way transmission member to drive the filtering device to move to the top of the discharge chute 22 to discharge unfiltered construction waste, and to move the crushing scale of the crushing device during the movement.

[0033] Among them, a storage trough 27 is also installed on the base 1. Construction waste that falls into the filtering device after being crushed and is smaller than the filter hole can pass through the filtering device and fall into the storage trough 27. Construction waste that is not successfully filtered needs to be crushed again.

[0034] In detail, in this embodiment, the construction waste recycling and processing system described in the utility model is adopted. When in use, the crushing device is first started, and then a batch of sorted construction waste is dumped into the discharge chute 22. The construction waste falls from the discharge end of the discharge chute 22 to the crushing device. The high-speed rotating crushing device crushes the construction waste. At this time, construction waste with a smaller diameter falls into the filtering device through the gap between the crushing devices without being crushed. After the construction waste in the filtering device accumulates to a certain weight, the mobile driving part is started to drive the filtering device to move to the upper end of the discharge chute 22. When the filtering device is not moved, it abuts against the blocking part. At this time, the discharge chute 22 is in a conducting state. The movement of the filtering device causes the blocking part to lose its extrusion, and the blocking part drives the discharge chute 22 under the elastic action. The discharging end performs a blocking operation so that the construction waste in the chute 22 cannot fall and be crushed. When the filtering device is at the upper end of the chute 22, under the action of gravity, the construction waste that has not been crushed falls into the chute 22 again. In the process of driving the filtering device to move, the mobile driving member controls the crushing scale of the crushing device through the one-way transmission member, thereby reducing the crushing diameter of the crushing device. After the dumping of the construction waste in the filtering device is completed, the mobile driving member is controlled to drive the filtering device to reset. When the filtering device is reset, the blocking member is squeezed again, thereby causing the blocking member to move relative to the chute 22, releasing the blocking state of the discharging end of the chute 22, and starting the crushing structure again, thereby realizing the secondary crushing of the construction waste, realizing the crushing of construction waste of different diameters, and reducing the workload of subsequent screening.

[0035] See also Figure 2 The pulverizing device includes a bidirectional screw rod 16, which is rotatably mounted on the support frame 23. A group of symmetrically arranged threaded sleeves 19 are threadedly connected to the bidirectional screw rod 16, and a gear roller 17 is rotatably mounted on the threaded sleeve 19. The gear roller 17 is driven to rotate by a motor 18 slidably mounted on the support frame 23.

[0036] First, the two motors 18 are controlled to work simultaneously. The motor 18 drives the output shaft to rotate. When the output shaft rotates, it drives the gear roller 17 to rotate accordingly. Under the high-speed rotating tilt, the clamping teeth on the gear roller 17 produce a huge crushing pressure on the fallen construction waste, thereby achieving the crushing of the construction waste. Among them, a gap is formed between the two gear rollers 17, and the construction waste smaller than this gap is not crushed and directly falls into the filtering device, thereby completing the crushing of construction waste with a larger diameter.

[0037] See also Figure 3 The filtering device includes a material receiving trough 6, one end of which is fixedly connected to the movable driving member, and a filter plate 7 is slidably installed in the material receiving trough 6. The filter plate 7 is arranged in an L-shaped structure and an inclined surface is formed on one side with a filter hole;

[0038] It also includes a spring 9 , one end of which is fixedly connected to the filter plate 7 , and the other end of which is fixedly connected to the material receiving trough 6 .

[0039] The blocking member includes a second telescopic member 20 fixedly mounted on the mounting seat 25, a blocking plate 21 fixedly mounted on one end of the second telescopic member 20, the blocking plate 21 can slide relative to the material discharge chute 22 to open or close the material discharge chute 22, and a pulley 24 is also rotatably mounted on one end of the second telescopic member 20.

[0040] The crushed construction waste falls into the collecting trough 6. Construction waste smaller than the filter holes passes through the filter holes under the action of gravity and falls into the storage trough 27. The construction waste that is not filtered in the collecting trough 6 needs to be crushed again. At this time, the collecting trough 6 and the pulley 24 are in abutment state, which produces an extrusion force on the pulley 24, causing the second telescopic member 20 to undergo elastic deformation, thereby allowing the sealing plate 21 to release the sealing work on the discharge end of the discharge trough 22, so that the construction waste in the discharge trough 22 can be discharged and crushed smoothly.

[0041] See also Figure 4 The mobile driving member includes an electric telescopic rod 3, which is fixedly mounted on the base 1 through a mounting frame 2, and a first telescopic member 5 is fixedly connected to the movable end of the electric telescopic rod 3, one end of the first telescopic member 5 is fixedly connected to the material receiving trough 6, and a ratchet plate 10 is fixedly mounted on the other end;

[0042] It also includes a guide rail 4 , which is fixedly mounted on the mounting frame 2 , and a columnar member 8 symmetrically arranged on the first telescopic member 5 is slidably mounted on the guide rail 4 .

[0043] The mounting seat 25 is fixedly mounted with symmetrically arranged extrusion pieces 26

[0044] When it is necessary to perform secondary crushing of the construction waste in the receiving trough 6, the electric telescopic rod 3 is started, and the electric telescopic rod 3 drives the first telescopic member 5 to move in the vertical direction. When the first telescopic member 5 moves, it drives the receiving trough 6 and the columnar member 8 to move synchronously. Under the limiting action of the guide rail 4, the receiving trough 6 moves along the track of the guide rail 4. During the movement, the squeezing of the pulley 24 by the receiving trough 6 gradually disappears until the pulley 24 is completely separated from the receiving trough 6. At this time, when the receiving trough 6 is about to move to the upper end of the discharge trough 22, the squeezing member 26 abuts against the filter plate 7, thereby squeezing the filter plate 7 to move relative to the receiving trough 6. When the filter plate 7 moves, the spring 9 is squeezed. The spring 9 is squeezed to reserve elastic potential energy, so that the construction waste in the receiving trough 6 falls into the discharge trough 22, so as to realize the secondary crushing of the construction waste.

[0045] See also Figure 5The one-way transmission member includes a first transmission shaft 12, which is rotatably mounted on the base 1, and a ratchet 11 adapted to the ratchet plate 10 is fixedly mounted on the first transmission shaft 12. The first transmission shaft 12 is rotatably connected to a second transmission shaft 14 rotatably mounted on the base 1 through a bevel gear set 13, and the second transmission shaft 14 is rotatably connected to the bidirectional screw 16 through a belt 15.

[0046] Furthermore, when the first telescopic member 5 drives the ratchet plate 10 to move close to the ratchet wheel 11, the pawl on the ratchet plate 10 engages with the ratchet wheel 11, thereby driving the ratchet wheel 11 to rotate. When the ratchet wheel 11 rotates, it drives the first transmission shaft 12 to rotate accordingly. When the first transmission shaft 12 rotates, it drives the second transmission shaft 14 to rotate through the bevel gear set 13. When the second transmission shaft 14 rotates, it drives the bidirectional screw rod 16 to rotate through the belt 15 to achieve the transmission requirement. When the bidirectional screw rod 16 rotates, it drives the threaded sleeve 19 to make a linear motion along the axial direction of the bidirectional screw rod 16, thereby reducing the gap between the two tooth rollers 17, so as to achieve the crushing work of construction waste of different sizes.
