The recycling of construction materials is mainly concentrated in the municipal and construction fields, and is used to make concrete aggregates, recycled blocks, paving bricks, etc.

[0003] To recycle construction waste, it is mainly necessary to crush it. According to the recycling needs, the construction waste can be crushed into recycled materials of the required particle size. In the crushing process, there are many types of building materials, including slag, abandoned soil and other wastes generated during the construction, laying or demolition and repair of various buildings, structures, pipelines, etc., with different hardness. Some building materials even contain metal materials such as steel bars. The environmentally friendly building material processing equipment in the existing technology is difficult to process a variety of building materials compatibly. Moreover, during the processing process, harder materials (such as stones, steel bars, etc.) are easy to damage the recycling equipment.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, the utility model provides an environmentally friendly building material processing device, comprising a crushing mechanism 1 and a grinding mechanism 2 arranged in an upper and lower arrangement, wherein the crushing mechanism 1 comprises a feed hopper 101, and a driving roller 102 and a driven roller 103 that mesh with each other are provided at the lower end of the feed hopper 101, wherein the driving roller 102 rotates under the drive of a driving motor and drives the driven roller 103 to rotate together;

[0028] The two ends of the driven roller 103 are respectively equipped with sliding shafts 104, which are slidably installed on the support seat 105 and the support leg 107. The sliding shaft 104 is provided with a shoulder 1041, and the shaft section between the shoulder 1041 of the sliding shaft 104 and the support leg 107 is sleeved with a first compression spring 106. Building materials are put into the feed hopper 101, and the building materials are pre-crushed during the rotation of the active roller 102 and the driven roller 103. When the building materials are hard, the driven roller 103 can be pushed away from the active roller 102 to avoid jamming and damage to the equipment.

[0029] After being pre-crushed by the crushing mechanism 1, the crushed material enters the grinding mechanism 2 at the lower end through the conveying pipe. Figure 3 The grinding mechanism 2 includes a static grinding disc 201 and a dynamic grinding disc 202 that rotate with each other. The static grinding disc 201 is fixedly mounted on the upper end of the rotatable dynamic grinding disc 202. A driving shaft 211 is fixed to the lower end of the dynamic grinding disc 202. The driving shaft 211 is rotatably mounted on the mounting plate 206 through a rotatable linear bearing.

[0030] An annular material storage trough 209 is provided below the edge of the movable grinding disc 202, and the ground building materials fall into the material storage trough 209. A material stripping plate 203 is fixed to the lower surface of the movable grinding disc 202, and the material stripping plate 203 extends into the material storage trough 209. A material discharge port is provided at the bottom of the material storage trough 209. The movable grinding disc 202 drives the material stripping plate 203 to rotate, so that the material stripping plate 203 moves the material in the material storage trough 209, causing the material to flow out from the discharge pipe 204 to realize material discharge.

[0031] A sliding cylinder 205 is provided at the lower end of the movable grinding disc 202. The bottom of the movable grinding disc 202 is rotatably mounted on the top of the sliding cylinder 205 through a first slewing bearing 210. The sliding cylinder 205 is sleeved on the drive shaft 211. The lower end opening of the sliding cylinder 205 is snapped onto the boss on the upper side of the mounting plate 206. A second compression spring 207 is provided in the sliding cylinder 205. When the movable grinding disc 202 moves downward, it pushes the sliding cylinder 205 to move downward and compresses the second compression spring 207. A vertically arranged limit groove is provided at the lower end of the sliding cylinder 205, and a limit protrusion matching the limit groove is provided on the mounting plate 206. The two cooperate with each other to enable the sliding cylinder 205 to slide up and down relative to the mounting plate 206 but not to rotate relative to each other.

[0032] The mounting plate 206 is provided with a mounting hole through which an adjustment screw 208 is inserted. The upper end of the adjustment screw 208 passes through the second compression spring 207 and is threadedly connected to the top wall of the sliding cylinder 205. Turning the adjustment screw 208 adjusts the preload force of the second compression spring 207, thereby adjusting the contact force between the static grinding disc 201 and the dynamic grinding disc 202, and thus the fineness of the final recycled material output. In addition, the dynamic grinding disc 202 is elastically configured to prevent building material blocks from getting stuck in the grinding gap and automatically adapt to the size of the building material blocks. The recycled material formed after grinding by the grinding mechanism 2 is discharged from the discharge pipe 204 and collected.

[0033] The driving shaft 211 is driven by the driving mechanism 3, as shown in FIG. Figure 4 The drive mechanism 3 includes a main gear 301 mounted on the drive shaft 211. The drive shaft 211 is provided with a limiting protrusion along its axial direction, and a limiting groove is provided on the main gear 301 to cooperate with the limiting protrusion. The main gear 301 is driven by a power unit (not shown), and the drive mechanism 3 rotates the drive shaft 211 without affecting the vertical movement of the drive shaft 211. The main gear 301 is rotatably mounted on the mounting base 303 via a second slewing bearing 302.

[0034] The specific working principle of this utility model:

[0035] The present invention includes a crushing mechanism 1 and a grinding mechanism 2 arranged in an upper and lower arrangement. The crushing mechanism 1 includes an active roller 102 and a driven roller 103. Both ends of the driven roller 103 are respectively installed with sliding shafts 104. The sliding shafts 104 are slidably installed on a support seat 105 and a support leg 107. Building materials are put into the feed hopper 101. The active roller 102 and the driven roller 103 rotate to pre-crush the building materials. When the building materials are hard, the driven roller 103 can be pushed away from the active roller 102 to avoid jamming and damage to the equipment.

[0036] The lower end of the sliding cylinder 205 is provided with a vertical limit groove, and the mounting plate 206 is provided with a limit protrusion that cooperates with the said limit groove. The two cooperate with each other so that the sliding cylinder 205 can slide up and down relative to the mounting plate 206 but cannot rotate relative to each other. The movable grinding disc 202 can move up and down under the action of the second compression spring 207. The preload force of the second compression spring 207 can be adjusted by rotating the adjusting screw 208, thereby adjusting the fitting force between the static grinding disc 201 and the movable grinding disc 202, thereby adjusting the fineness of the final recycled material output.
