Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a building construction waste compression device. Background Technology

[0002] Construction waste refers to the waste generated during the construction of buildings, mainly including discarded concrete blocks, broken bricks and tiles, wood scraps, scrap steel bars, plastic packaging materials, and various leftover building materials. If these wastes are not properly disposed of, they will cause environmental pollution.

[0003] Current construction waste compression devices often achieve the effect of directly compressing the waste after crushing it, making it easier to transport. For example, Chinese Patent Publication No. CN221361830U discloses a construction waste compression device including a housing. Inside the housing, a crushing drum is rotatably connected via bearings. A gear is installed at the end of the crushing drum. A motor housing is installed at the rear of the housing, containing a drive motor. This construction waste compression device, through the arrangement of a disc, positioning slider, round rod, connecting rod, dust collection cylinder, dust collection hose, support plate, dust collection box, dustproof net, and exhaust fan, facilitates the collection of dust particles during the crushing and compression process. The crushing is achieved through the crushing drum, compression is performed inside the collection box by the pressure plate, and dust is collected by the exhaust fan and dust collection cylinder. The positioning slider and connecting rod allow for easy adjustment of the dust collection cylinder's position, expanding the absorption range and improving practicality.

[0004] Although the aforementioned application documents can achieve a good compression and dust collection effect, in actual use, due to the long construction cycle, construction waste often contains some water after rain or snow during the construction process. At this time, the presence of water can easily affect the compaction effect of the waste. Therefore, a construction waste compression device is proposed to solve the above problems.

A roller is provided at the bottom of the liquid storage tank 76. The roller ensures that the friction between the liquid storage tank 76 and the control chamber 4 is small, thereby ensuring that the force required to pull and push the liquid storage tank 76 in the horizontal direction is small.

[0041] Reference Figure 3 , Figure 4 and Figure 6 The pressing chamber 8 is equipped with a baffle assembly 9, which includes two baffles 91. The ends of the two baffles 91 that are close to each other are rounded to ensure that the two baffles 91 do not obstruct each other when rotating.

The locking block 95 is concave in shape, and the lowest point of the top protrusion of the locking block 95 is higher than the height of the highest point of the control block 710.

[0043] Working principle: When in use, the staff first put the garbage into the feed hopper above the crushing chamber 2, so that the garbage can be crushed during the rotation of the crushing roller 51 after entering the crushing chamber 2. After the garbage is crushed, it can generate a force to move to the left under the control of the inclined surface at the bottom of the crushing chamber 2.

[0044] At the same time, the cylinder 61 is in the starting state, so the output shaft of the cylinder 61 drives the pressure plate 62 to move up and down reciprocally. When the pressure plate 62 moves downward, the baffle plate 65 contacts the protrusion on the inner wall of the housing 1, and the baffle plate 65 can completely block the feed inlet 63. Therefore, when the cylinder 61 moves downward to the point of entering the pressing box 8, the garbage inside the crushing chamber 2 cannot enter the compression chamber 3.

[0045] When the pressure plate 62 moves downward to the area where the control block 710 is located, the control block 710 is pushed and moves towards the inlet 78 and the installation chamber 79. This causes the gas that was originally inside the inlet 78 and the installation chamber 79 to enter the pneumatic pipe 71. The gas pushes the moving block 72, causing it to move to the left. This loosens the pull rope 73, so the spring 75 is no longer under tension. Under the action of the elastic force, the spring 75 pushes the control plate 74, causing it to move to the right. This also causes the liquid storage tank 76 and the conveying tank 77 to move to the right, so that the liquid storage tank 76 is below the pressing box 8.

[0046] At this time, as the pressure plate 62 moves downward to compact the waste under the drive of the cylinder 61, the liquid waste is squeezed out and can then enter the interior of the liquid storage tank 76.

[0047] After compaction is completed, the pressure plate 62 moves from bottom to top under the drive of the cylinder 61. When the pressure plate 62 moves away from the area where the control block 710 is located, the control block 710 moves towards the direction of entering the housing 1 under the elastic force of the spring 711, so that the gas inside the air pressure pipe 71 is sucked into the moving port 78 and the installation chamber 79. Therefore, at this time, the moving block 72 moves to the right under the action of air pressure, thereby pulling the pull rope 73, which pulls the control plate 74 to the left, thereby causing the liquid storage tank 76 and the conveying tank 77 to move to the left, so that the conveying tank 77 is positioned below the pressing box 8.

[0048] Since the lowest point of the bidirectional block 99 is higher than the highest point of the control block 710, when the pressure plate 62 contacts the bidirectional block 99, the conveyor box 77 is located below the pressing box 8. When the pressure plate 62 contacts the bidirectional block 99 from bottom to top, the bidirectional block 99 cannot rotate upwards. Therefore, it moves forward after being subjected to force on its inclined surface, thereby driving the locking block 95 to move forward, so that the locking block 95 leaves the locking slot 97.

[0049] After the card block 95 leaves the slot 97, the garbage pushes the baffle 91 under the action of gravity. After the garbage leaves the pressing box 8 through the gap created by the rotation of the baffle 91, the baffle 91 is not under force at this time. Therefore, the baffle 91 can be reset under the action of the torsion spring 93. After resetting, the baffle 91 first pushes the inclined surface of the bottom of the card block 95, and then moves until the card block 95 is exactly at the same horizontal position as the slot 97. Then, the card block 95 enters the slot 97 under the elastic force of the spring 96.

[0050] As the pressure plate 62 continues to move upward, it leaves the area where the pressing box 8 is located. Therefore, it can be driven to move upward by the protrusion above the baffle plate 65, so that the opening of the baffle plate 65 moves to the area where the feed inlet 63 is located, and the newly crushed waste can smoothly enter the pressing box 8.

[0051] Since the bidirectional block 99 can rotate downwards after being subjected to force from above, when the pressure plate 62 comes into contact with the bidirectional block 99 from above, it will not push the bidirectional block 99, and thus the bidirectional block 99 will not cause the card block 95 to leave the card slot 97. Therefore, during the downward movement, the garbage that has entered the pressing box 8 and has not yet been compressed will not leave the pressing box 8 under the action of gravity.

[0052] Meanwhile, whenever the liquid storage tank 76 moves to the position below the pressing tank 8, the conveying tank 77 tilts as it moves to the right, so that the waste block inside it can leave the housing 1 through the opening on the right side of the control chamber 4.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
