DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0037] The utility model provides Figure 1-5 The construction waste treatment and transportation device shown comprises a main frame 1, a transmission roller 2 is movably arranged between the left and right wall panels of the main frame 1, and a transmission belt 3 is sleeved on the surface of the transmission roller 2.

[0038] A motor 4 is fixed at the bottom of the main frame 1, and the shaft of the motor 4 is connected to the transmission roller 2 through a pulley 5 and a power belt 6. There are two pulleys 5, which are respectively fixedly sleeved on the shaft of the motor 4 and the end position of the transmission roller 2 set at the front of the main frame 1, and the power belt 6 is sleeved on the surface of the two pulleys 5. The rotation of the shaft of the motor 4 drives one of the pulleys 5 to rotate, and the pulley 5 drives the power belt 6 to rotate. The other pulley 5 is driven to rotate by the power belt 6, and drives the transmission roller 2 at the leading position of the front of the device to rotate, thereby driving the transmission belt 3 to move.

[0039] A first bevel gear 7 is fixedly sleeved at the end of the shaft of the motor 4 , a second bevel gear 8 is meshed at the top side of the first bevel gear 7 , and a bottom rod 9 is fixedly sleeved at the axial center position of the second bevel gear 8 .

[0040] A crushing bucket 10 is arranged above the conveyor belt 3, and a crushing wheel 11 is rotatably arranged inside the crushing bucket 10, and a worm wheel 12 is arranged at the end of the crushing wheel 11, and a worm 13 is meshed on the side of the worm wheel 12, and a top rod 14 is fixedly sleeved inside the worm 13. The surfaces of the top rod 14 and the bottom rod 9 are both movably sleeved with a shaft seat, which is fixedly connected to the main frame 1, and a bearing is embedded inside the shaft seat, and the bearings of the upper and lower shaft seats are fixedly sleeved with the top rod 14 and the bottom rod 9 respectively. The shaft seat and the bearing limit and maintain the height position of the top rod 14 and the bottom rod 9, so that they can only rotate with their own axis as the center of the circle.

[0041] A connecting mechanism 15 is sleeved between the bottom rod 9 and the top rod 14 .

[0042] The connecting mechanism 15 includes a hexagonal shaft 1501, and there are two hexagonal shafts 1501. The two hexagonal shafts 1501 are arranged coaxially in the vertical direction. The top hexagonal shaft 1501 is welded to the bottom end of the top rod 14, and the bottom hexagonal shaft 1501 is welded to the top of the bottom rod 9. There is a gap between the facing ends of the upper and lower hexagonal shafts 1501. The radial length of the bottom hexagonal shaft 1501 is 1.2 to 1.5 times that of the transmission sleeve 1502, and the screwing position of the limit bolt 1503 is at one-third of the bottom hexagonal shaft 1501 from bottom to top. The transmission sleeve 1502 is pulled upward until its top end is sleeved on the surface of the hexagonal shaft 1501 on the top side, and the limiting bolt 1503 is screwed in to limit and maintain the height of the transmission sleeve 1502. At this time, the rotation of the bottom rod 9 will drive the transmission sleeve 1502 and the top rod 14 to rotate accordingly, realizing the linkage of the top rod 14 and the bottom rod 9, and realizing the linkage of the transmission belt 3 and the crushing wheel 11. When the limiting bolt 1503 and the hexagonal shaft 1501 are unlocked, the transmission sleeve 1502 will fall down along the axial direction of the bottom rod 9 under the influence of its own gravity, so that the top end of the transmission sleeve 1502 is separated from the hexagonal shaft 1501 on the top side. At this time, the rotation of the bottom rod 9 will not affect the hexagonal shaft 1501 on the top side, that is, the top rod 14 will not rotate with the bottom rod 9, so that the motor 4 can only drive the transmission belt 3 to move, and the crushing wheel 11 will not follow the movement.

[0043] A transmission sleeve 1502 is disposed on the surface of the bottom hexagonal shaft 1501 , the inner surface shape of the transmission sleeve 1502 matches the outer surface shape of the hexagonal shaft 1501 , and the upper and lower ends of the transmission sleeve 1502 are respectively inserted and sleeved with the upper and lower hexagonal shafts 1501 .

[0044] The side surface of the bottom hexagonal shaft 1501 is threadedly connected with a limiting bolt 1503 , and the limiting bolt 1503 abuts against the bottom end surface of the transmission sleeve 1502 .

[0045] A flange 1504 is provided at the bottom edge of the bottom hexagonal shaft 1501 .

[0046] A screening mechanism 16 is fixed on the top of the crushing bucket 10 .

[0047] The screening mechanism 16 includes a screening frame 1601, the front of which extends beyond the front of the crushing bucket 10 toward the front of the device, and the bottom of the front of the screening frame 1601 faces the front end of the conveyor belt 3. Construction waste is put into the front opening of the screening frame 1601, and the waste will move to the rear side of the device, that is, the position of the crushing bucket 10, when it contacts the guide plate 1602. When the size is smaller than the width of the current feeding gap 1603, the waste will fall. The screening frame 1601 is fixed on the top of the crushing bucket 10. The screening frame 1601 is a U-shaped structure with an opening at the front. A guide plate 1602 is fixed on the inner side of the screening frame 1601. There are two guide plates 1602. The two guide plates 1602 are symmetrically arranged. The guide plates 1602 are inclined from front to back and from the side to the horizontal median line of the guide frame. A material discharge gap 1603 is formed between the relative edges of the two guide plates 1602. The material discharge gap 1603 is a trapezoidal structure that is narrow in the front and wide in the back.

[0048] The working principle of the utility model is as follows: construction waste is put into the front opening of the screening frame 1601. Since the feeding gap 1603 is narrow at the front and wide at the back, small particles of waste directly pass through the feeding gap 1603 and fall to the front leading position of the conveyor belt 3. Large diameter waste blocks slide backward along the guide plate 1602 into the crushing bucket 10 and fall into the bite gap between the two crushing wheels 11.

[0049] The shaft of the motor 4 rotates through the transmission of the pulley 5 and the power belt 6, driving the transmission roller 2 and the transmission belt 3 to rotate;

[0050] At the same time, the shaft of the motor 4 drives the bottom rod 9 to rotate through the redirection operation of the first bevel gear 7 and the second bevel gear 8.

[0051] When crushing operation is required, the transmission sleeve 1502 is pulled up to the joint gap position of the upper and lower hexagonal shafts 1501, and the two ends of the transmission sleeve 1502 are respectively sleeved on the surfaces of the upper and lower hexagonal shafts 1501, and the limit bolt 1503 is screwed onto the surface of the bottom hexagonal shaft 1501 to maintain the height position of the transmission sleeve 1502.

[0052] At this time, the rotation effect of the bottom rod 9 can be transmitted through the transmission sleeve 1502, driving the top rod 14 to follow and make coaxial movement. The rotation of the top rod 14 drives the worm wheel 12 and the worm 13 to rotate, so that the crushing wheel 11 crushes the large particles of waste.

[0053] When the crushing wheel 11 is stuck and the conveyor belt 3 needs to be emptied of materials, or there is no crushing operation requirement and only the conveyor belt 3 needs to be transported independently, the limit bolt 1503 is unlocked and removed from the surface of the hexagonal shaft 1501, and the transmission sleeve 1502 falls to the bottom end of the bottom hexagonal shaft 1501 under its own gravity and is limited by the flange 1504. At this time, the transmission sleeve 1502 is separated from the top hexagonal shaft 1501, and the bottom rod 9 will rotate independently when driven by the motor 4, and the top rod 14 will not rotate. The shaft of the motor 4 only drives the conveyor belt 3 through the pulley 5, and the crushing wheel 11 does not move with the conveyor belt 3. Only the conveyor belt 3 is started without starting the crushing wheel 11.

[0054] It is convenient to empty the material on the surface of the conveyor belt 3 when the crushing wheel 11 is repaired, and it also meets the requirement of not starting the crushing wheel 11 when only small particles of sand and mud are transported, thereby saving electric energy.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
