DETAILED DESCRIPTION

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] Example 1

[0044] A construction waste sorting and recycling device, such as Figure 1-4 As shown, it includes a base plate 1, a frame 2, a barrel 3, a first spring 4 and a crushing mechanism 5. The frame 2 is installed on the top right side of the base plate 1, and the barrel 3 is slidably connected to the top left side of the frame 2. Two first springs 4 are sleeved on the right side of the barrel 3. The two first springs 4 are symmetrical front and back. The left end of the first spring 4 is connected to the barrel 3, and the right end of the first spring 4 is connected to the frame 2. A crushing mechanism 5 is provided on the top right side of the frame 2, and the crushing mechanism 5 is used to crush cement in construction waste.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, the crushing mechanism 5 includes a first support frame 51, a cylinder 52, a first sliding frame 53, a guide rod 54, a threaded guide frame 55, an extrusion block 56 and a second spring 57. The first support frame 51 is installed on the right side of the top of the frame 2, and the cylinder 52 is installed on the upper part of the first support frame 51. The left end of the telescopic rod of the cylinder 52 is connected to the first sliding frame 53, and the guide rod 54 is installed on the top of the first support frame 51. The first sliding frame 53 is slidably connected to the guide rod 54. A threaded guide frame 55 is installed in the middle of the top of the frame 2. An extrusion block 56 is slidably connected in the threaded guide frame 55. The extrusion block 56 is used to crush construction waste. The extrusion block 56 is located above the barrel 3. A second spring 57 is connected between the extrusion block 56 and the threaded guide frame 55. The top end of the second spring 57 is connected to the upper part of the extrusion block 56, and the bottom end of the second spring 57 is connected to the top of the threaded guide frame 55.

[0046] When it is necessary to sort and recycle construction waste, the user can first pull the barrel 3 to move to the right, compress the first spring 4, place the construction waste in the barrel 3, and then release the barrel 3. Under the action of the first spring 4, the barrel 3 moves to the left and resets, pushing the construction waste to the bottom of the extrusion block 56, and then start the cylinder 52. The telescopic rod of the cylinder 52 moves to the left, driving the first sliding frame 53 to move to the left. The first sliding frame 53 moves to the left and drives the extrusion block 56 to move downward. At the same time, the extrusion block 56 rotates along the threaded guide frame 55, the second spring 57 is compressed, and the extrusion block 56 presses the construction waste to the bottom of the extrusion block 56. The construction waste is crushed, because the steel bar is relatively hard and will not be crushed. After the construction waste is crushed, the control cylinder 52 drives the first sliding frame 53 to move rightward and reset. Under the action of the second spring 57, the extrusion block 56 moves upward and resets, and then the cylinder 52 is closed. The user manually pushes the barrel 3 to move leftward to push out the crushed construction waste. The first spring 4 is stretched. After the crushed construction waste falls to the ground, the barrel 3 is released. Under the action of the first spring 4, the barrel 3 moves rightward and resets. At this time, the user can pick out the reusable steel bars for recycling. In this way, the construction waste can be placed through the barrel 3, and the cement in the construction waste can be crushed through the crushing mechanism 5, which is convenient for the user to pick out the reusable steel bars for recycling, so as to achieve the purpose of separating the cement and steel bars in the construction waste and effectively recycling the reusable objects in the construction waste.

[0047] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a screening mechanism 6 is also included, which is used to separate steel bars and cement. The screening mechanism 6 includes a first support plate 61, a screening frame 62, a sliding rod 63, a first guide rail 64, a first connecting block 65, a filter frame 66, a clamping block 67 and a rotating block 68. The first support plate 61 is installed on the left side of the lower part of the frame 2, and a sliding rod 63 is slidably installed in the middle of the first support plate 61. The left end of the sliding rod 63 is connected to the screening frame 62, and the inner wall of the screening frame 62 is slidably connected to the filter frame 66. The first connecting blocks 65 are installed on both the front and rear sides of the outer wall of the screening frame 62. Two first guide rails 64 are installed on the left side of the middle part of the frame 2. The two first guide rails 64 are symmetrical front and back. The first connecting block 65 is slidably connected to the first guide rail 64. Four clamping blocks 67 are installed at even intervals along the circumferential direction at the lower part of the screening frame 62. The inner side of the clamping block 67 is rotatably connected to the rotating block 68, and the rotating block 68 can resist the bottom of the filter frame 66.

[0048] The material barrel 3 is pushed to move to the left to push out the crushed construction waste, and the crushed construction waste will fall into the screening frame 62. The user manually pushes the screening frame 62 to move back and forth to screen the crushed construction waste. The cement in the screening frame 62 will fall to the lower part of the filter frame 66, and the steel bars will remain on the top of the filter frame 66. When the screening is completed, the user takes out the steel bars on the top of the filter frame 66, and then manually rotates the rotating block 68 so that the rotating block 68 no longer abuts against the bottom of the filter frame 66, takes out the filter frame 66 and pours out the cement. In this way, the screening mechanism 6 can screen the crushed construction waste, easily separate the steel bars and cement, and facilitate operation.

[0049] Example 2

[0050] On the basis of Example 1, Figure 1 , Figure 8 and Fig. 9 As shown, a dust removal mechanism 7 is also included. The dust removal mechanism 7 is used to reduce dust. The dust removal mechanism 7 includes a second support plate 71, a nozzle 72 and a connecting pipe 73. Two second support plates 71 are installed on the left side of the top of the frame 2. The two second support plates 71 are both located on the outside of the barrel 3, and the two second support plates 71 are symmetrical front to back. A connecting pipe 73 is installed on the upper part of the second support plate 71, and a nozzle 72 is installed on the inner end of the connecting pipe 73. The nozzle 72 is connected to the middle part of the second support plate 71, and the nozzle 72 is located obliquely above the barrel 3.

[0051] When the squeezing block 56 crushes the construction waste, a lot of dust will be generated. The user can connect the water pipe to the connecting pipe 73, and then turn on the faucet to let water flow into the connecting pipe 73. The water is sprayed onto the construction waste in the barrel 3 through the nozzle 72 to wet the construction waste and reduce dust. After the crushing work is completed, the faucet is turned off. In this way, the dust removal mechanism 7 can wet the construction waste and reduce the dust generated during the crushing process.

[0052] like Figure 1 , Fig.10 and Fig.11As shown, it also includes a separation mechanism 8, which is used to suck up the steel bars from the top of the filter frame 66. The separation mechanism 8 includes a bracket 81, a material collection box 82, a fixed pulley 83, a rope 84, a first slider 85, a second guide rail 86, a second sliding frame 87, a magnet 88, a third spring 89, a support block 810 and a connecting frame 811. The bracket 81 is installed on the left side of the top of the bottom plate 1, and the right side of the middle of the bracket 81 is connected to the two first guide rails 64. The middle of the bracket 81 is installed with a material collection box 82, and the material collection box 82 is located on the left side of the screening frame 62. The second sliding frame 87 is slidably connected between the upper parts of the bracket 81, and two ropes 84 are connected to the right side of the second sliding frame 87. The two ropes 84 are symmetrical front and back. Two support blocks 810 are installed on the left side of the top of the frame 2, and the two support blocks 810 are symmetrical front and back. The two support blocks 810 are both slidably connected to the second sliding frame 87, and a third spring 89 is connected between the two support blocks 810 and the second sliding frame 87. The left end of the third spring 89 is connected to the second sliding frame 87, and the right end of the third spring 89 is connected to the support block 810. A plurality of magnets 88 are installed at the bottom of the second sliding frame 87, and the magnets 88 are located above the material receiving box 82. A connecting frame 811 is installed on the left side of the top of the frame 2, and the connecting frame 811 is located between the barrel 3 and the two second support plates 71. Two fixed pulleys 83 are rotatably connected to the upper part of the connecting frame 811, and the two fixed pulleys 83 are symmetrical front and back. Second guide rails 86 are installed on the front and back sides of the outer wall of the material receiving box 82, and the first slider 85 is slidably connected to the top of the second guide rail 86, and the tail end of the rope 84 passes around the fixed pulley 83 and is connected to the first slider 85.

[0053] After screening the crushed construction waste, the first slider 85 is pulled to move to the left, and the first slider 85 moves to the left, driving the second slider 87 to move to the right through the rope 84 and the fixed pulley 83, and the third spring 89 is compressed, and the second slider 87 moves to the right, driving the magnet 88 to move to the right, and the magnet 88 sucks up the steel bars on the top of the filter frame 66, and then the first slider 85 is released. Under the action of the third spring 89, the second slider 87 moves to the left and resets, driving the magnet 88 to move to the left and reset, and the magnet 88 transports the steel bars to the top of the material receiving box 82. The user manually pulls the steel bars to separate the steel bars from the magnet 88, and the user can put the steel bars into the material receiving box 82 for temporary storage. In this way, the separation mechanism 8 can suck up the steel bars from the top of the filter frame 66 and transport the steel bars to the material receiving box 82 for temporary storage, which further facilitates the operation.

[0054] like Figure 1 , Fig.12 and Fig.13As shown, it also includes a disengagement mechanism 9, which is used to remove the steel bars adsorbed on the magnet 88.

The top of the fourth spring 93 is connected to the second sliding frame 87, and the bottom of the fourth spring 93 is connected to the disengagement block 92.

[0055] Pressing the pressing block 91 downward drives the disengaging block 92 downward, the fourth spring 93 is compressed, and the disengaging block 92 removes the steel bars adsorbed on the magnet 88, so that the steel bars automatically fall into the receiving box 82. After the steel bars are removed, the pressing block 91 is released, and the disengaging block 92 moves upward and resets under the action of the fourth spring 93. In this way, the disengaging mechanism 9 can remove the steel bars adsorbed on the magnet 88, so that the steel bars automatically fall into the receiving box 82, thereby preventing the user's hands from being stabbed by the steel bars.

[0056] Example 3

[0057] On the basis of Example 2, Figure 1 , Fig.14 and Fig.15 As shown, it also includes an automatic knocking mechanism 10, which is used to automatically screen steel bars and cement. The automatic knocking mechanism 10 includes a second support frame 101, an electric push rod 102, a second slider 103 and a connecting rod 104. The second support frame 101 is installed in the middle of the frame 2, and the electric push rod 102 is installed on the second support frame 101. The second slider 103 is connected to the left side of the electric push rod 102, and two connecting rods 104 are installed on the left side of the second slider 103. The two connecting rods 104 are symmetrical front and back, and the two connecting rods 104 are both slidably connected to the first support plate 61, and the left sides of the two connecting rods 104 are connected to the screening frame 62.

[0058] The electric push rod 102 is started, and the electric push rod 102 drives the second slider 103 to move back and forth, and the connecting rod 104 moves back and forth accordingly, and the connecting rod 104 moves back and forth to drive the screening frame 62 to move back and forth to screen the crushed construction waste. After the screening is completed, the electric push rod 102 is closed. In this way, the function of automatically screening the crushed construction waste is realized through the automatic knocking mechanism 10, which saves manpower.

[0059] like Figure 1 , Fig.16 and Fig.17As shown, it also includes an automatic pushing mechanism 11, which is used to automatically push the crushed construction waste to the top of the screening frame 62. The automatic pushing mechanism 11 includes a third guide rail 111, a second connecting block 112, an L-shaped rod 113, an A-shaped inclined block 114 and a fifth spring 115. Two third guide rails 111 are installed on the left side of the middle part of the frame 2, and the two third guide rails 111 are symmetrical front to back. Second connecting blocks 112 are installed on the front and back sides of the outer wall of the barrel 3.

The top end of the fifth spring 115 is connected to the first sliding frame 53, and the bottom end of the fifth spring 115 is connected to the A-shaped inclined block 114.

[0060] After the construction waste is crushed, the control cylinder 52 drives the first sliding frame 53 and the components thereon to continue to move to the left, and the A-shaped inclined block 114 moves to the left accordingly and pushes the L-shaped rod 113 to move to the left. The L-shaped rod 113 moves to the left and drives the second connecting block 112 to move to the left, and the barrel 3 moves to the left accordingly and pushes the crushed construction waste to the top of the screening frame 62, so that the crushed construction waste can automatically fall into the screening frame 62. When the barrel 3, the second connecting block 112 and the L-shaped rod 113 can no longer move to the left, the A-shaped inclined block 114 moves upward, and the fifth spring 115 is compressed. When the A-shaped inclined block 114 is separated from the L-shaped rod 113, the barrel 3 automatically returns to the right under the action of the first spring 4. The A-shaped inclined block 114 is in position, and under the action of the compression of the fifth spring 115, the A-shaped inclined block 114 is reset downward, and then the cylinder 52 drives the first sliding frame 53 and the components thereon to reset to the right, and the A-shaped inclined block 114 contacts the L-shaped rod 113 again, and drives the L-shaped rod 113, the second connecting block 112 and the barrel 3 to move to the right, and the first spring 4 is compressed. At this time, people can place construction waste in the barrel 3. When the L-shaped rod 113 can no longer move to the right, the A-shaped inclined block 114 can again cross the L-shaped rod 113, and under the action of the first spring 4, the L-shaped rod 113, the second connecting block 112 and the barrel 3 are reset to the left, so that people do not need to manually pull the barrel 3 to the right, and finally close the cylinder 52. In this way, the automatic pushing mechanism 11 enables the barrel 3 to automatically push the crushed construction waste to the top of the screening frame 62, so that the crushed construction waste can fall into the screening frame 62, and automatically push the barrel 3 to the right to facilitate material unloading, further saving manpower.
