[0002] Construction waste is the solid waste generated during the construction, renovation, expansion or demolition of buildings. Depending on the source of construction waste, it can be divided into construction waste and demolition waste. Construction waste, as the name suggests, is the solid waste generated during the construction, renovation or expansion projects, while demolition waste is the construction waste generated during the demolition of buildings. Nowadays, building materials are generally crushed for secondary use.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention can achieve grinding and crushing of building materials through the extrusion block and the crushing disk. The shape of the bottom of the extrusion block is set to fit the shape of the upper surface of the crushing disk. As the extrusion block and the crushing disk are constantly approaching each other, the gap for building materials to enter gradually becomes smaller, which can reduce the amount of building materials entering, and ultimately achieve intermittent feeding of building materials, avoiding continuous feeding, which may cause the annular groove on the surface of the crushing disk to become blocked due to excessive material accumulation, and also prevent the entire device from being overloaded due to excessive crushing pressure caused by excessive feeding of building materials. The surface of the crushing disk is designed to be high in the middle and low around, which can effectively filter some of the wastewater in the building materials, prevent excessive mixing of water and materials, and prevent some of the wet materials from adhering to the inner wall of the device when grinding wet materials, thereby affecting the grinding and crushing effect of the entire device on the materials.

[0017] 2. This device is equipped with a crushing rod to crush the soil blocks on the surface of the crushing disk, thereby increasing the degree of crushing of the soil blocks and preventing the soil blocks from being ground and flattened by the crushing disk and the bottom of the extrusion block, and adhering to the surfaces of the two, or being blocked on the upper surface of the annular groove, resulting in the problem that the entire device cannot effectively grind and crush the soil blocks. At the same time, the crushing rod can rotate along the inside of the annular groove to crush the material on the inner wall of the annular groove, thereby avoiding the problem that some materials accumulate on the inner wall of the annular groove, resulting in the ground material being unable to be filtered and collected through the annular groove.

[0018] 3. The spring belt pushes the fixed plate and the annular plate, so that the fixed plate and the annular plate can slide downward along the outer surface of the crushing bar, removing the wet material or soil attached to the outer surface of the crushing bar, avoiding the presence of wet materials such as soil on the surface of the crushing bar, thereby affecting the subsequent crushing effect of the crushing bar on the soil.

[0019] 4. This device can absorb dust from the construction material placement and crushing process through the cooperation of the dust collection device and the dust collection box, preventing the dust from drifting to the outside and affecting the external environment. The rotation of the scraper plate can scrape some of the dust attached to the inner wall of the fixed frame to the side close to the dust collection device, making it easier for the dust collection device to absorb it, and avoid certain areas inside the fixed frame where the dust absorbed into the fixed frame cannot be completely absorbed by the dust collection device due to the weak dust collection wind force. The rotation of the scraper plate can push the wet construction waste on the surface of the extrusion block, preventing the wet waste from accumulating on the upper surface of the extrusion block and being unable to slide to the surface of the crushing disk for subsequent crushing.

[0020] 5. The upper surface of the curved plate of this device is designed to fit the shape of the inner wall of the extrusion block. During the reciprocating motion of the curved plate, the moisture inside the extrusion block can be released to the upper surface of the extrusion block. On the one hand, the release of water flow can reduce the degree of dust dispersion. On the other hand, the water flow can clean the surface of the scraper plate, weaken the adhesion of construction waste on the scraper plate surface, and avoid affecting the scraping effect of the scraper plate on the waste on the upper surface of the extrusion block.

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0032] For example 1, please refer to Figure 1-Figure 5The present invention provides a technical solution: a building material crusher includes a crushing drum 1, the bottom of the crushing drum 1 is fixedly connected to a support frame 2, the top of the support frame 2 is fixedly connected to a lifting rail 3, the outer surface of the lifting rail 3 is slidably connected to a lifting platform 4, the side of the lifting platform 4 away from the lifting rail 3 is fixedly connected to a connecting block 5, a crushing mechanism 6 is arranged above the connecting block 5, and a dust suction mechanism 7 is fixedly connected to the bottom of the connecting block 5; the support frame 2 provides support for the crushing drum 1 and the bottom of the lifting rail 3, the lifting platform 4 can slide up and down along the outer surface of the lifting rail 3, the crushing mechanism 6 crushes the building materials, and the dust suction mechanism 7 absorbs dust during the crushing process.

[0033] First, the building materials are put into the crushing drum 1, and the lifting platform 4 can slide up and down along the surface of the lifting rail 3, thereby controlling the up and down movement of the dust collection mechanism 7, and cooperating with the crushing mechanism 6 to grind and crush the building materials.

[0034] The crushing mechanism 6 includes a connecting frame 61, the inner wall of the connecting frame 61 is fixedly connected to a motor 62, the output end of the motor 62 is fixedly connected to a rotating shaft 63, the bottom of the rotating shaft 63 is fixedly connected to a crushing disk 64, the inner wall of the crushing disk 64 is provided with an annular groove 65, the bottom of the crushing disk 64 is fixedly connected to a waste water tank 66, and an extrusion component 67 is provided above the crushing disk 64; the connecting frame 61 provides support for the motor 62, the annular groove 65 is convenient for filtering the crushed building powder, the outer surface of the crushing disk 64 is provided with a plurality of through holes for filtering moisture, and the shape of the crushing disk 64 is designed to be high in the middle and low on all sides to facilitate the sliding of building materials, and the waste water tank 66 collects the moisture contained in the building materials.

[0035] When building materials are placed into the crushing drum 1, the motor 62 is started, which can drive the rotation of the crushing disk 64 through the rotating shaft 63. The building materials slide from the upper surface of the extrusion component 67 to the upper surface of the crushing disk 64. Some of the wastewater contained in the building materials penetrates into the interior of the wastewater tank 66 through the filter holes on the upper surface of the crushing disk 64, and is collected separately. This can prevent the water from mixing with the building materials, causing the building materials to become wet and affecting the crushing of the building materials by the entire device. The lifting platform 4 slides downward along the surface of the lifting rail 3, which can control the extrusion component 67 to slide downward, getting closer and closer to the crushing disk 64, and jointly achieve grinding and crushing of the building materials. The crushed building material powder falls through the annular groove 65 to the inner wall of the crushing drum 1 below, and slides down to be collected separately by external staff. The shape of the crushing disk 64 is designed to be high in the middle and low on all sides, which makes it easy for the building materials to slide from the middle to the surrounding areas, while some water can be filtered out.

[0036] The extrusion component 67 includes an extrusion block 671, the inner wall of which is provided with a water outlet 672, a limiting groove 673, and a chute 674. A crushing component 675 is slidably connected to the inner wall of chute 674. The extrusion block 671 cooperates with the crushing disk 64 to grind and pulverize the building materials. The chute 674 facilitates the upward and downward movement of the crushing component 675. The inner wall of the extrusion block 671 is provided with an annular water trough. Under certain conditions, water in the trough can flow through the water outlet 672 to the outer surface of the extrusion block 671.

[0037] The side of the support frame 2 away from the motor 62 is fixedly connected to the outer surface of the lifting rail 3, the outer surface of the crushing disk 64 is rotatably connected to the inner wall of the crushing cylinder 1, and the outer surface of the extrusion block 671 is slidably connected to the inner wall of the crushing cylinder 1.

[0038] When the lifting platform 4 controls the extrusion component 67 to move downward, the extrusion block 671 moves downward with it. Since the crushing disk 64 is constantly rotating, the building materials slide from the upper surface of the extrusion block 671 to the center of the crushing disk 64 below, and then slide from the center of the crushing disk 64 to the surrounding areas. The continuous downward movement of the extrusion block 671 and the rotation of the crushing disk 64 work together to grind and crush building materials of different sizes.

[0039] As the extrusion block 671 gets closer and closer to the crushing disk 64, the gap between the lower surface of the extrusion block 671 and the upper surface of the crushing disk 64 becomes smaller and smaller, so that large building materials will not enter the grinding area of ​​the crushing disk 64 and the extrusion block 671, and intermittent feeding of building materials can be achieved, ensuring that the building materials ground each time are moderate and the machine will not be overloaded due to excessive materials.

[0040] When the squeezing block 671 moves downward, the bottom of the chute 674 pushes the crushing component 675 to move upward, thereby assisting in crushing the building materials through the crushing component 675 .

[0041] Crushing component 675 includes a fixed plate 6751, with a spring band 6752 fixedly connected to the top of fixed plate 6751. Ring plates 6753 are fixedly connected to both sides of fixed plate 6751, and crushing rods 6754 are slidably connected to the inner walls of ring plates 6753. Fixed plate 6751 can move ring plates 6753 up and down along the inner walls of slide groove 674, and ring plates 6753 slide along the inner walls of retaining groove 673 during this movement.

[0042] Both sides of the fixed plate 6751 are slidingly connected to the inner wall of the slide groove 674, the top of the spring belt 6752 is fixedly connected to the inner wall of the extrusion block 671, the outer surface of the annular plate 6753 is slidingly connected to the inner wall of the limiting groove 673, and the top of the breaking rod 6754 is fixedly connected to the inner wall of the extrusion block 671.

[0043] During the downward movement of the extrusion block 671, the bottom of the slide groove 674 will push the fixed plate 6751 to move upward and squeeze the spring belt 6752. The fixed plate 6751 will also drive the annular plate 6753 to move upward. During the upward movement, the fixed plate 6751 and the annular plate 6753 will slide along the outer surface of the breaking rod 6754 until the fixed plate 6751 moves to the inner wall of the extrusion block 671 and the annular plate 6753 moves to the inside of the limiting groove 673.

[0044] When the fixed plate 6751 and the annular plate 6753 are fully moved to the interior of the extrusion block 671, the crushing disc 64 rotates and together with the bottom of the extrusion block 671, grinds and crushes the building materials. The crushing rod 6754 assists in crushing the building materials on the surface of the crushing disc 64 by poking the clods and other materials on the surface of the crushing disc 64, preventing the clods from being flattened by the crushing disc 64 and the extrusion block 671 and being unable to fall out of the annular groove 65. At the same time, as the extrusion block 671 continues to move downward, the bottom of the crushing rod 6754 gradually penetrates into the annular groove 65, crushing the clods or building materials that are blocking the annular groove 65, and preventing the materials from accumulating inside the annular groove 65, causing the annular groove 65 to be blocked and unable to filter the building materials.

[0045] When a batch of building materials is completely crushed, the extrusion block 671 moves upward, causing the building materials on the surface of the extrusion block 671 to slide down to the center of the crushing disk 64 and further slide down to the remaining upper surface of the crushing disk 64. As the extrusion block 671 returns to its original position and moves upward, the spring belt 6752 causes the fixing plate 6751 to move the annular plate 6753 downward along the outer surface of the crushing bar 6754, thereby removing any clods of earth adhering to the surface of the crushing bar 6754 and preventing the surface of the crushing bar 6754 from adhering to mud or damp materials, which would otherwise reduce the auxiliary crushing effect of the crushing bar 6754.

[0046] For example 2, please refer to Figures 1-9The present invention provides a technical solution: based on the first embodiment, the dust collection mechanism 7 includes a dust collection box 71, an upper suction plate 72 is fixedly connected to the bottom of the dust collection box 71, and a suction hole 73 is formed on the outer surface of the upper suction plate 72. A lower suction plate 74 is provided below the upper suction plate 72. A scraping component 75 is rotatably connected to the inner wall of the lower suction plate 74. The scraping component 75 is slidably connected to a fixing frame 76 on the side away from the lower suction plate 74. A dust collection device 77 is fixedly connected to the inner wall of the fixing frame 76. The dust collection box 71 is arranged in an annular shape to facilitate the absorption of construction dust around the extrusion block 671. The scraping component 75 can scrape dust off the inner wall of the fixing frame 76. The dust collection device 77 is used to absorb dust during the delivery and crushing of construction materials. There are multiple dust collection devices 77.

[0047] The top of the dust box 71 is fixedly connected to the bottom of the connecting block 5 , the bottom of the lower suction plate 74 is fixedly connected to the upper surface of the extrusion block 671 , and the bottom of the fixing frame 76 is fixedly connected to the upper surface of the extrusion block 671 .

[0048] When building materials are placed on the upper surface of the extrusion block 671 and are ground and crushed, a large amount of dust is generated. The dust is absorbed by the dust suction device 77 in conjunction with the dust suction box 71, the upper suction plate 72, the lower suction plate 74, and the fixing frame 76. The dust suction box 71 is arranged in an annular shape, which facilitates the effective absorption of dust floating around the extrusion block 671.

[0049] The scraping component 75 includes a fixed column 751, below which is disposed a water inlet pipe 752. A circular slide 753 is fixedly connected to the bottom of the fixed column 751. A slide 754 is slidably connected to the outer surface of the circular slide 753. A scraping plate 755 is fixedly connected to the bottom of the slide 754. A scraping plate 756 is fixedly connected to the side of the scraping plate 755 away from the water inlet pipe 752. A connecting rod 757 is fixedly connected to the bottom of the scraping plate 755. A striking ball 758 is fixedly connected to the bottom end of the connecting rod 757. A water discharge component 759 is slidably connected to the outer surface of the striking ball 758. The fixed column 751 serves to secure the circular slide 753. The scraping plate 755 can scrape dust off the inner wall of the fixed frame 76. The striking ball 758 triggers the water discharge component 759 during its rotation. The water inlet pipe 752 is connected to the inner wall of the extrusion block 671 , and a certain amount of water can be supplied to the internal space of the extrusion block 671 through the water inlet pipe 752 so that the water does not spread to the area of ​​the scraping component 75 above.

[0050] The scraper plate 755 rotates and slides along the inner surface of the fixed frame 76, scraping some dust inside the fixed frame 76 to the side close to the dust suction device 77 to prevent dust from entering the dust suction box 71 due to the weak dust suction wind force in some areas, resulting in dust residue on the inner surface of the fixed frame 76. The scraper box rotates and slides along the outer surface of the upper suction plate 72 and the lower suction plate 74, and can scrape off some dust and plastic bags on the surfaces of the upper suction plate 72 and the lower suction plate 74, to prevent dust from being blocked in the suction holes 73 of the upper suction plate 72 and the lower suction plate 74, and to prevent plastic bags from adhering to the outer surfaces of the upper suction plate 72 and the lower suction plate 74, resulting in some suction holes 73 being blocked, resulting in a problem of reduced dust suction effect.

[0051] The water discharge component 759 includes an extrusion belt 7591. A round block 7592 is fixedly connected to the end of the extrusion belt 7591 away from the water inlet pipe 752. A slide plate 7593 is fixedly connected to the side of the slide plate 7592 away from the extrusion belt 7591. The lower surface of the slide plate 7593 is slidably connected to a limit frame 7594. A curved plate 7595 is fixedly connected to the end of the slide plate 7593 away from the round block 7592. The extrusion belt 7591 is made of elastic material and has elasticity and reset functions. The limit frame 7594 provides a limit for the movement of the slide plate 7593. The curved plate 7595 can fit against the inner wall of the extrusion block 671, blocking the water outlet 672. The curved plate 7595 is designed to fit the inner wall of the extrusion block 671.

[0052] The top of the fixed column 751 is fixedly connected to the top of the inner wall of the dust box 71, the end of the water inlet pipe 752 close to the dust box 71 is fixedly connected to the inner wall of the extrusion block 671, the outer surface of the scraper plate 755 is slidably connected to the bottom of the upper suction plate 72, the outer surface of the scraper plate 755 is slidably connected to the top of the lower suction plate 74, the outer surface of the scraper plate 755 is slidably connected to the inner wall of the fixed frame 76, the end of the extrusion belt 7591 away from the round block 7592 is fixedly connected to the inner wall of the extrusion block 671, and the bottom of the limiting frame 7594 is fixedly connected to the inner wall of the extrusion block 671.

[0053] When the slide 754 drives the scraper plate 755 to rotate, the scraper plate 755 will also drive the rotation of the connecting rod 757 and the impact ball 758. The impact ball 758 will touch the outer surface of the round block 7592 during rotation and push the round block 7592 to move toward the side close to the extrusion belt 7591. The round block 7592 will drive the movement of the slide plate 7593 and the curved plate 7595 during movement. When the curved plate 7595 moves toward the side close to the extrusion belt 7591, it will break contact with the inner wall of the extrusion block 671. Therefore, some water inside the extrusion block 671 flows out through the water outlet 672 on the surface of the extrusion block 671. On the one hand, the dust on the upper surface of the extrusion block 671 can be cleaned and some dust can be reduced. On the other hand, the outflowing water can clean the surface of the scraper plate 756 to prevent the scraper plate 756 from being attached to the surface of the scraper plate 756. The scraping effect of the scraper plate 756 on the surface of the extrusion block 671 is affected.

[0054] The specific working process of the present invention is as follows:

[0055] First, the building materials are put into the center of the crushing drum 1. Through the rotation of the crushing disk 64 inside the crushing mechanism 6 and the downward movement of the extrusion block 671 inside the extrusion component 67, the intermittent feeding and grinding of the building materials can be achieved.

[0056] By setting the crushing rod 6754 inside the crushing component 675, the soil blocks on the surface of the crushing disk 64 can be broken up when the crushing disk 64 rotates, and the building materials blocked inside the annular groove 65 can be crushed, thereby preventing the soil blocks from being ground and flattened by the crushing disk 64 and the extrusion block 671 and blocking the upper surface of the annular groove 65. At the same time, it also avoids the problem that some building materials are blocked inside the annular groove 65, resulting in the annular groove 65 being unable to effectively filter the remaining ground building materials.

[0057] The dust collecting device 77 inside the dust collecting component can absorb the dust generated during the construction material delivery and crushing process, preventing the dust from drifting to the outside and affecting the environment and the life safety of the workers.

[0058] The scraper plate 755 inside the scraping component 75 can scrape off the dust attached to the inside of the fixed frame 76, avoiding the problem that some areas of the internal space surrounded by the fixed frame, the upper suction plate, the lower suction plate, and the dust box, due to the low dust suction wind force, cause some of the dust inside the fixed frame 76 to adhere to the inner surface of the fixed frame and cannot be effectively absorbed by the dust suction device 77. The scraping effect of the scraper plate 756 on the suction holes 73 on the outer surfaces of the upper suction plate 72 and the lower suction plate 74 can prevent dust and materials such as plastic bags from clogging the suction holes 73, resulting in a reduced dust adsorption effect. The sliding of the scraper plate 756 along the surface of the extrusion block 671 can push down the wet material attached to the surface of the extrusion block 671, avoiding the problem that the wet material always accumulates on the upper surface of the extrusion block 671 and affects the subsequent grinding and crushing of the material.

[0059] Finally, the reciprocating motion of the arc plate 7595 inside the water discharge component 759 can release the moisture inside the extrusion block 671. On the one hand, it can reduce the dispersion of dust on the surface of the extrusion block 671. On the other hand, it can clean the surface of the scraper plate 756, remove the wet or sticky materials attached to the surface, and reduce the stickiness of the material to the scraper plate 756.
