Technical Field

[0001] The utility model relates to the technical field of construction waste, in particular to a waste recycling machine for engineering construction. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying or demolition of buildings, structures, pipe networks, etc. At present, the main method of treating construction waste includes landfill, but there are also some new explorations, such as converting it into renewable resources through construction waste production lines, such as sand making equipment that can process construction waste into sand and gravel materials for road construction, etc.

[0003] When recycling existing construction waste, it is usually first passed through a crusher to break up large pieces of rotating structures. However, large concrete bricks have steel bars inside, which makes it more difficult to crush the bricks and easily causes the crusher to become blocked, which not only reduces the crushing efficiency but also easily causes damage to the equipment.

[0004] In order to solve the above problems, a garbage recycling machine for engineering construction is designed. Utility Model Content

[0026] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0027] like Figure 1-Figure 6 As shown, a garbage recycling machine for construction provided in this embodiment includes a transmission frame 1, and a shield frame 2 fixedly installed on the transmission frame 1, a gas processing mechanism 3 is sealedly installed on the outer top of the shield frame 2, and a crushing mechanism 4 is arranged between the inner walls of the shield frame 2; the gas processing mechanism 3 includes an exhaust chamber 301 fixedly installed on the outer top of the shield frame 2, a filter layer plate 302 is slidably arranged in the inner wall of the exhaust chamber 301, and two sets of exhaust fans 303 are installed on the top of the exhaust chamber 301; the crushing mechanism 4 includes a roller with the inner wall of the shield frame 2 Two connecting shafts 408 are dynamically installed, and fixing sleeves 409 fixed with bolts are evenly distributed on the outer walls of the two connecting shafts 408. A connecting rod 410 is welded and fixed to one side of the outer wall of the fixing sleeve 409, and a breaker 401 is welded and installed on the bottom of the connecting rod 410; the connecting shaft 408 extends to the outer wall of the shield frame 2, and both ends are sleeved with a second transmission assembly 407, and one side of the outer side of the second transmission assembly 407 is equipped with two mutually meshing driven gear sets 402, and the outside of one gear in the driven gear set 402 is also meshed with a driving residual gear 403.

[0028] In the above embodiment, the conveyor belt of the transmission frame 1 is driven by a separate motor, and a horizontal plate support is provided between the upper and lower conveyor belts to prevent the solid waste from collapsing to a lower position during transmission. The fixed sleeve 409 rotates synchronously with the connecting shaft 408, thereby driving the bottom breaker 401 to rise and fall. When the driving residual gear 403 is engaged with the tooth groove, the connecting shaft 408 is driven to rotate, and the breaker 401 is raised to the maximum position. When the tooth groove loses engagement with the driven gear set 402, the breaker hammers 401 on both sides descend under the action of gravity. At the same time, the bottom of the breaker hammer 401 is 10 cm higher than the conveyor belt, so that the conveyor belt can clamp and crush large pieces of solid waste. If there is no large solid connection, the breaker hammers 401 will stop after collision.

[0029] The filter layer plate 302 is composed of two layers of replaceable primary filters, and regular replacement of the filter layer plate 302 can ensure the filtering effect of dust and gas.

[0030] A protruding column 411 is integrally formed on the outer wall of the breaker 401, and a transmission shaft 404 is fixedly inserted into the driving residual gear 403. The transmission shaft 404 and the outer wall of the shield frame 2 are rotationally mounted through a bearing limiter. The protruding column 411 is made of steel and can effectively impact and destroy the concrete structure. A first transmission assembly 406 is sleeved in the middle part of the transmission shaft 404, and a servo motor 405 fixed to the outer wall of the shield frame 2 is installed on one side of the outer side of the first transmission assembly 406.

[0031] The inner wall of the shield frame 2 is a spherical structure, and the bottom edge of the inner wall of the shield frame 2 is aligned with the top edge of the inner wall of the transmission frame 1. The inner wall of the transmission frame 1 is a protective side plate of the conveyor belt, which is used to limit the transmission of the transported solid waste. After its top is aligned with the bottom of the inner wall of the shield frame 2, the debris generated by the impact and crushing of the breaker 401 splashes onto the inner wall of the shield frame 2, and slides down along the inner wall of the shield frame 2 to the conveyor belt for continued transportation, avoiding residual accumulation in the inner wall of the shield frame 2.

[0032] The breaker 401 is a solid structure, and the connecting rod 410 is made of rubber. The kinetic energy of the rebound after the breaker 401 hits the concrete block is absorbed by the rubber connecting rod 410, avoiding an impact on the top structure.

[0033] Working principle of the device: When the device is in use, it is connected to an external power supply and an external control device.

[0034] The feeding mechanism puts the construction solid waste onto the conveyor belt on the conveyor frame 1 for transportation. At the same time, the servo motor 405 drives the transmission shaft 404 to rotate stably on one side of the outer wall of the shield frame 2 through the first transmission assembly 406. The driving residual gears 403 at both ends of the transmission shaft 404 rotate, driving the driven gear set 402 on one side to rotate. The driven gear set 402 consists of two meshing gears with opposite rotation directions. Then, the two connecting shafts 408 rotate stably on the inner top of the shield frame 2, driving the fixed sleeve 409, the connecting rod 410 and the breaker 401 to swing. When the driving residual gear 403 is meshed with the driven gear set 402, the breaker 401 swings upward to the maximum position, and then drives the residual gear 4 03 continues to rotate and loses the meshing drive of the driven gear set 402. The breaker 401 falls freely and swings downward with the opposite breaker 401 to hit the solid connection stored on the conveyor belt, so that it is disintegrated and crushed into smaller block structures under the impact of the raised column 411. The undisintegrated and crushed solid waste can be continuously hit under the action of subsequent multiple groups of breaker hammers 401 to ensure the crushing effect. The refined construction waste is transported backward and enters the new crushing mechanism 4 for processing, which can reduce the volume of large-volume solid waste such as concrete bricks and foam bricks, and at the same time reduce the adhesion of the internal steel bars, thereby avoiding the subsequent crushing equipment from being blocked and frequently maintained, thereby ensuring the efficient operation of the equipment.

[0035] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
