When the material passes through the first movable jaw plate and the fixed jaw plate, the material is squeezed and crushed, so that after being squeezed, the material is broken and the volume becomes smaller. At the same time, the steel bar is separated from the material and falls into the material box;

[0016] S2. When the crushed material falls into the upper end of the sliding material inclined surface, it will slide into the space between the grinding cylinder and the second cone groove along the sliding material inclined surface track. Through the rotation of the grinding cylinder, the side wear-resistant layer and the second cone groove grind and crush the internal material. Then the crushed material falls between the grinding inclined surface and the outer surface of the fitting grinding surface. The grinding inclined surface and the fitting grinding surface grind the material again, so that the grinding cylinder and the inner wall of the grinding base form relative motion.

[0017] S3. Through the cooperation of the annular collecting pipe groove and the discharging rack, when the polished material falls through the lower end of the grinding cylinder and the inner wall of the grinding base, it will fall into the inside of the annular collecting pipe groove, and then the material will slide along the bottom surface of the annular collecting pipe groove into the discharging rack, and then the discharging rack will pour out the material for collection and processing.

[0018] The present invention has the following beneficial effects:

[0019] 1. The construction solid waste recycling and reuse device can adjust the distance between the cone bar and the second movable jaw plate and the fixed jaw plate through the cooperation of the internal structure of the driving shell, and realize the volume adjustment function of the material after extrusion, so that the device can change the distance between the second movable jaw plate and the cone bar and the fixed jaw plate according to the material conditions on site, treat the materials differently, and make flexible adjustments, so that the device has the crushing effect of various materials. While crushing, the support spring and the movable inner shaft will form a buffer function to avoid the presence of difficult-to-crush materials in the materials and cause damage to the device.

[0020] 2. The construction solid waste recycling and reuse device provides an outward expansion force for the arc plate through an elastic shaft, and pushes the arc plate outward, so that the outer side of the arc plate always forms a resistance pressure with the outer surface of the grinding bevel, and increases the friction effect between the two, and improves the fineness of grinding. The grinding bevel and the fitting grinding surface are in an inclined state, so that when grinding, the material will automatically fall into the lower end of the grinding cylinder for collection and processing. Through the action of the inclined grinding shaft, the friction between the grinding cylinder and the inner wall of the grinding box can be increased, and the grinding effect between the two can be improved, so that the material forms a more delicate state, and can be directly recycled after grinding, so that the device has the ability to improve the grinding effect and the subsequent grinding operation of the material.

[0021] 3. The construction solid waste recycling and reuse device crushes the incoming construction waste through the cooperation of the first movable jaw plate, the second movable jaw plate and the fixed jaw plate, and separates the steel bars from the materials during the crushing process. The crushed materials will fall into the material holding box along the second movable jaw plate, the cone bar and the fixed jaw plate, and the materials will fall out along the coarse-grained filter screen to complete the collection of the steel bars.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] When in use, construction solid waste is placed on the upper end of the crushing box 3, and the material is made to fall between the first movable jaw plate 13 and the second movable jaw plate 14 through the dividing cone plate 6. At the same time, the driving shaft 4 is driven to rotate by the second driving motor 48, and then the driving shaft 4 is connected to the rotating shaft frame 5 through a belt, and the driving shaft 4 and the rotating shaft frame 5 are symmetrically installed on both sides of the crushing box 3. When the rotating shaft frame 5 rotates, it drives the connecting plate 10 to rotate, so that the connecting plate 10 drives the first connecting shaft 11 and the second connecting shaft 12 to move around the axis of the connecting plate 10, and the first movable jaw plate 13 is pulled by the connecting rod 46 and the connecting sleeve 47 to swing left and right, and a conical state with a larger top and a smaller bottom is formed between the cone bar 15 and the second movable jaw plate 14 and the fixed jaw plate 16.

[0035] When the material passes through the first movable jaw plate 13 and the fixed jaw plate 16, the material is squeezed and crushed, so that after being squeezed, it breaks and becomes smaller in size. As it becomes smaller, it falls downward and is pressed again. The cycle is repeated and the material is squeezed multiple times to form a crushing function of the material. Through the continuous squeezing of the cone bar 15 and the second movable jaw plate 14, the volume of the material becomes smaller and smaller until it is discharged from between the first movable jaw plate 13 and the fixed jaw plate 16.

[0036] At the same time, the oil is connected to the external device through the external pipe 25, so that the oil is transported to the diverter groove 45 through the external pipe 25, and then sent to the two sides of the inside of the drive housing 19 by the diverter groove 45, forming a driving force for the extension shaft 20 to expand outward, extending outward through the support spring 22, and driving the movable inner shaft 21 to expand outward, thereby changing the distance between the second movable jaw plate 14 and the cone bar 15 and the lower end of the fixed jaw plate 16, so as to adjust the volume of the material after extrusion. Through the cooperation of the internal structure of the drive housing 19, the distance between the cone bar 15 and the second movable jaw plate 14 and the fixed jaw plate 16 can be adjusted, and the volume adjustment effect of the material after extrusion can be achieved, so that the device can change the distance between the second movable jaw plate 14 and the cone bar 15 and the fixed jaw plate 16 according to the material conditions on site, treat the materials differently, and flexibly adjust them, so that the device has the crushing effect of various materials. While crushing, the support spring 22 and the movable inner shaft 21 form a buffering function to avoid the presence of difficult-to-crush materials in the material, which causes damage to the device.

[0037] Example 2

[0038] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-8 An external tube 25 is installed at the upper end of the driving housing 19, a grinding cylinder 17 is installed inside the grinding box 2, a sliding inclined surface 18 is provided on the outer side of the grinding cylinder 17, a grinding base 28 is provided inside the grinding box 2, a grinding inclined surface 29 is provided inside the grinding base 28, a fitting grinding surface 30 is provided on the lower surface of the grinding cylinder 17, a second conical groove 50 is installed on the inner wall of the grinding box 2, a side wear-resistant layer 26 is installed on the outer side of the grinding cylinder 17, the fitting grinding surface 30 is used to fit on the upper surface of the grinding inclined surface 29, and a bevel wear-resistant layer 42 is installed on the upper surface of the grinding inclined surface 29.

[0039] After the material is crushed, its volume is still large and it is difficult to recycle it directly. However, through the action of the grinding cylinder 17, when the crushed material falls into the upper end of the sliding material inclined surface 18, it will slide along the trajectory of the sliding material inclined surface 18 into between the grinding cylinder 17 and the second conical groove 50. Through the rotation of the grinding cylinder 17, the side wear-resistant layer 26 and the second conical groove 50 grind and crush the internal material. Then the crushed material falls between the grinding inclined surface 29 and the outer surface of the bonding grinding surface 30, and the material is polished again by the grinding inclined surface 29 and the bonding grinding surface 30. The cross-sectional structure between the grinding inclined surface 29 and the bonding grinding surface 30 is in an inclined state, so that the material will automatically fall into the lower end of the grinding cylinder 17 during grinding. Through the structure inside the grinding box 2, the material will be polished again and the fineness of the material will be increased, so that the material directly meets the recycling standard, so that the material can be directly recycled, and no subsequent grinding operation is required.

[0040] Example 3

[0041] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-8 An oblique grinding shaft 27 is installed on the outer side of the side wear-resistant layer 26, and a bottom grinding roller 32 is installed on the inner side of the grinding surface 30. The oblique grinding shaft 27 and the bottom grinding roller 32 have the same structure.

[0042] Four oblique grinding shafts 27 are arranged in a circular array at the lower end of the fitting grinding surface 30. When the grinding cylinder 17 rotates, the oblique grinding shafts 27 roll on the lower surface of the fitting grinding surface 30 and contact the upper surface of the inclined wear-resistant layer 42. Through the action of the oblique grinding shafts 27, the grinding degree between the two can be further increased, the grinding effect of the device can be improved, and the material grinding can be more delicate.

[0043] Example 4

[0044] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-8 A square support roller 33 is provided on the outer side of the oblique grinding shaft 27, an elastic shaft 37 is installed on the outer side of the square support roller 33, an arc plate 34 is installed on the outer side of the elastic shaft 37, a limiting outer groove 35 is provided on the outer side of the arc plate 34, and a grinding layer 36 is installed in the limiting outer groove 35.

[0045] When in use, when the crushed material falls into the upper end of the sliding material inclined surface 18, it will slide into the space between the grinding cylinder 17 and the second conical groove 50 along the trajectory of the sliding material inclined surface 18. The grinding cylinder 17 and the inner wall of the grinding base 28 form relative movement through the rotation of the grinding cylinder 17, so that the side wear-resistant layer 26 and the second conical groove 50 grind the internal material. Then the crushed material will directly fall between the grinding inclined surface 29 and the outer surface of the fitting grinding surface 30. The elastic shaft 37 provides an outward expansion force for the arc plate 34, and pushes the arc plate 34 outward, so that the outer side of the arc plate 34 always forms a resistance pressure with the outer surface of the grinding inclined surface 29, thereby increasing the friction effect between the two and improving the fineness of the grinding.

[0046] The grinding bevel 29 and the contact grinding surface 30 are in an inclined state, so that when the material is being ground, it will automatically fall into the lower end of the grinding cylinder 17 for collection and processing. Through the action of the inclined grinding shaft 27, the friction between the grinding cylinder 17 and the inner wall of the grinding base 28 can be increased, and the grinding effect between the two can be improved, so that the material can be formed into a more delicate state, and can be directly recycled after grinding, so that the device has the ability to improve the grinding effect and the subsequent grinding operation of the material.

[0047] Example 5

[0048] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-8A placement groove 7 is symmetrically arranged on the outer side of the crushing box 3, a material holding box 8 is installed inside the placement groove 7, and a coarse-grained filter screen 9 is installed inside the material holding box 8.

[0049] Construction materials are usually mixed with steel bars inside, and when the materials are crushed, the presence of steel bars will affect the subsequent material crushing effect. The first movable jaw 13, the second movable jaw 14 and the fixed jaw 16 cooperate to crush the incoming construction waste, and at the same time, the steel bars are separated from the materials. The crushed materials will flow along the second movable jaw 14, the cone bar 15 and the fixed jaw 16 and fall into the material holding box 8, and the materials will fall out along the coarse-grained filter screen 9 to complete the collection of the steel bars. Through the cooperation of the material holding box 8 and the coarse-grained filter screen 9, the internal steel bars can be collected and processed after the materials are crushed, so as to facilitate subsequent cleaning and grinding operations.

[0050] Example 6

[0051] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-8 An annular material collecting pipe groove 44 is installed inside the polishing box 2, and a discharge rack 41 is provided on one side of the annular material collecting pipe groove 44. The annular material collecting pipe groove 44 is located at the lower end of the polishing cylinder 17.

[0052] The lower surface of the annular collecting pipe groove 44 is inclined and is inclined in the direction of the discharging rack 41. Through the cooperation between the annular collecting pipe groove 44 and the discharging rack 41, when the ground material falls through the lower end of the grinding cylinder 17 and the inner wall of the grinding base 28, it will fall into the inside of the annular collecting pipe groove 44, and then the material will slide along the bottom surface of the annular collecting pipe groove 44 into the inside of the discharging rack 41, and then the material will be poured out by the discharging rack 41. Through the above structure, the material can be collected and processed after grinding.

[0053] Example 7

For details, please refer to Figure 1-8 A base bearing 39 is also installed inside the grinding base 28, and the lower end of the grinding cylinder 17 is used to fit on the upper surface of the base bearing 39. A support column 49 is also installed inside the grinding base 28, and a first drive motor 40 is installed on the top of the support column 49. The inner wall of the grinding cylinder 17 is installed with a connecting inner gear ring 38.

[0055] A driving gear is installed at the upper end of the first driving motor 40, and the inner wall of the inner gear ring 38 is connected to the driving gear through tooth groove meshing transmission. By seating the lower surface of the grinding cylinder 17 on the upper surface of the base bearing 39, the inside of the connecting rod 46 is stuck in the inside of the grinding cylinder 17, and ensures that the inner wall of the inner gear ring 38 is in contact with the driving gear, and forms a tooth groove meshing connection state. Through the cooperation of the first driving motor 40 and the driving gear, the grinding cylinder 17 is driven to rotate as a whole, thereby providing rotational power support for the grinding cylinder 17.

[0056] Example 8

[0058] The second driving motor 48 rotates to drive the driving shaft 4, and then the driving shaft 4 and the rotating shaft frame 5 are driven by a belt transmission to drive the rotating shaft frame 5 to rotate, thereby driving the connecting disk 10 to move. Through the above structure, the driving force for the connecting disk 10 to rotate is provided.

[0059] Example 9

[0060] This embodiment is an improvement made on the basis of embodiment 8. For details, please refer to Figure 1-8 The lower end of the grinding cylinder 17 is also provided with a sweeping brush 31, and the sweeping brush 31 is obliquely arranged on the lower surface of the grinding surface 30.

[0061] When the grinding cylinder 17 is located inside the grinding base 28 and rotates, the sweeping bristles 31 will clean the material on the inner wall of the grinding base 28. Through the oblique state of the sweeping bristles 31 and the rotation of the grinding cylinder 17, the sweeping bristles 31 are driven to clean and gather the material inward and sweep it into the annular collecting pipe groove 44, so as to avoid the polished material remaining in the grinding base 28.

When the material passes through the first movable jaw plate 13 and the fixed jaw plate 16, the material is squeezed and crushed, so that after being squeezed, the material is broken and the volume becomes smaller. At the same time, the steel bar is separated from the material and falls into the material box 8;

[0065] S2. When the crushed material falls onto the upper end of the sliding material inclined surface 18, it will slide along the track of the sliding material inclined surface 18 into between the grinding cylinder 17 and the second conical groove 50. Through the rotation of the grinding cylinder 17, the side wear-resistant layer 26 and the second conical groove 50 grind and crush the internal material. Then, the crushed material falls between the outer surface of the grinding inclined surface 29 and the fitting grinding surface 30. The grinding inclined surface 29 and the fitting grinding surface 30 grind the material again, so that the grinding cylinder 17 and the inner wall of the grinding base 28 form relative motion.
