DETAILED DESCRIPTION
[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.
[0019] See also Figure 1 , Figure 2 and Figure 3This is a schematic diagram of the structure of the patent, an environmentally friendly asphalt crushing and recycling device, including a crushing box 1, brackets 2 are fixedly installed on the left and right sides of the bottom of the crushing box 1, a feed pipe 3 is embedded in the top of the crushing box 1, a crushing motor is fixedly installed on the outer rear side wall of the crushing box 1, the number of crushing motors is two, the front end of the rotating shaft of the crushing motor passes through the rear side wall of the crushing box 1 and is installed with a crushing roller 4, and a discharge pipe 5 is embedded in the bottom of the crushing box 1;
[0020] The outer wall of the discharge pipe 5 is threaded with a nut 6, and the bottom end of the outer wall of the discharge pipe 5 is integrally formed with a fixing ring 7;
[0021] A shielding cylinder 8 is fixedly installed in the middle of the inner top wall of the crushing box 1, and triangular plates 9 are integrally formed at the front and rear ends of the bottom of the shielding cylinder 8.
[0022] like Figure 2 As shown, the bottom of the shielding cylinder 8 is close to the top of the two crushing rollers 4, and the two triangular plates 9 are located at the front and rear sides of the top between the two crushing rollers 4, which can prevent the block asphalt falling from above from passing through the crushing rollers 4.
[0023] Specifically, the nut 6 includes an internal thread ring 10 and a pressure ring 11 . The outer wall of the discharge pipe 5 is provided with threads matching the internal thread ring 10 . The internal thread ring 10 is screwed onto the outer wall of the discharge pipe 5 , and the pressure ring 11 is sleeved onto the discharge pipe 5 .
[0024] The top of the bag containing crushed asphalt is sleeved on the top of the fixing ring 7. If it is directly pressed on the bag through the bottom of a nut, the nut will rotate and press against the bag, which will easily cause wear of the bag and make it inconvenient for recycling.
[0025] Specifically, the left and right ends of the outer wall of the discharge pipe 5 are provided with slide grooves 12 , and the left and right ends of the inner wall of the pressure ring 11 are integrally formed with sliders 13 , and the two sliders 13 are slidably installed in the two slide grooves 12 respectively.
[0026] The slider 13 is slidably installed in the slide groove 12 to limit the moving track of the pressure ring 11 so that it can only move up and down to avoid wear on the bag.
[0027] Specifically, the outer wall of the internal threaded ring 10 is provided with an annular groove 14, and a circular ring 15 is rotatably installed in the annular groove 14. The shape and size of the circular ring 15 match the internal shape and size of the annular groove 14. One end of a connecting rod 16 is fixedly installed on the left and right ends of the outer wall of the circular ring 15, and the other end of the connecting rod 16 is fixedly installed on the top of the pressure ring 11.
[0028] The circular ring 15 is arranged in the annular groove 14 of the internal thread ring 10 so that the internal thread ring 10 and the pressure ring 11 can rotate relative to each other. When the internal thread ring 10 moves up and down, the pressure ring 11 can also be driven to move up and down at the same time by the circular ring 15 and the connecting rod 16.
[0029] Specifically, a concave surface 17 is provided on the inner bottom wall of the crushing box 1 , and the lowest end of the concave surface 17 is connected to the discharge pipe 5 .
[0030] The concave surface 17 is provided to facilitate the crushed asphalt to enter the discharge pipe 5 .
[0031] Specifically, a first baffle 18 is integrally formed at the left end of the inner wall of the feed pipe 3, and a second baffle 19 is integrally formed at the right end of the inner wall of the feed pipe 3. Both the first baffle 18 and the second baffle 19 are inclined.
[0032] like Figure 2 As shown, by providing the first baffle 18 and the second baffle 19, it is possible to prevent asphalt from splashing out of the feed pipe 3 and injuring people when the asphalt is crushed by the crushing roller 4.
[0033] Working principle: Before crushing, the top inner side of the bag used to hold the crushed asphalt can be placed on the top of the fixed ring 7, and then the internal threaded ring 10 is rotated to drive the pressure ring 11 to move downward through the circular ring 15 and the connecting rod 16. The pressure ring 11 can only move downward and press on the bag due to the slider 13. The bag is connected to the discharge pipe 5 as a whole, and the block asphalt is put into the feed pipe 3. The asphalt is crushed by two crushing rollers 4, and the crushed asphalt directly enters the bag through the discharge pipe 5.
[0034] It should be noted that the equipment structure and drawings of this patent mainly describe the principles of this patent. In terms of the technology of this design principle, the settings of the device's power mechanism, power supply system and control system are not fully described. However, on the premise that technical personnel in this field understand the principles of the above patent, they can clearly know the details of its power mechanism, power supply system and control system.
[0035] This patent installs a discharge pipe at the bottom of the crushing box, a fixing ring is installed at the bottom end of the outer wall of the discharge pipe, and a nut is screwed on the outer wall of the discharge pipe. Before use, the top of the bag used to hold the crushed asphalt can be put on the top of the fixing ring, and then it is tightened and fixed by the nut. The crushed asphalt falling from the discharge pipe can directly enter the bag, avoiding causing a large amount of dust to pollute the surrounding environment and eliminating the subsequent asphalt packaging step.
