[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example
[0021] like Figures 1 to 13 As shown, a construction waste recycled aggregate preparation device includes a frame structure 1, a crushing and grinding box 2 fixedly connected inside the frame structure 1, a feed box 3 fixedly connected to the upper end of the crushing and grinding box 2, the upper port of the feed box 3 being open and larger than the lower port, and a discharge box 4 fixedly connected to the lower end of the crushing and grinding box 2. The frame structure 1 is also connected to a drive device 5. A rotating shaft 54 passes through the crushing and grinding box 2. The drive end of the drive device 5 is connected to the rotating shaft 54, and the drive device 5 drives the rotating shaft 54 to rotate. An arc-shaped perforated plate 41 is provided inside the crushing and grinding box 2, located below the rotating shaft 54. Several sets of blades 42 and grinding rods 43 horizontally placed on the surface of the blades 42 are provided on the outer surface of the rotating shaft 54. The sidewall of the grinding rod 43 contacts and grinds the raw material. The raw material ground to a suitable size enters the discharge box 4 from the perforation in the arc-shaped perforated plate 41.
[0022] It should be noted that the above solution is for reference only. Figure 1 , Figure 2 , Figure 3 and Figure 4 The structure shown in the figure is, of course, the method implemented in this embodiment: The crushing and grinding box 2, the feeding box 3, and the discharging box 4 are all provided in two sets, and the two sets of crushing and grinding boxes 2, the feeding box 3, and the discharging box 4 are arranged side by side. The rotating shaft 54 passes through the two sets of crushing and grinding boxes 2. That is, in this embodiment, two sets of crushing and grinding methods are used to crush and grind the asphalt raw materials. In actual use, for environmental protection requirements, the asphalt raw materials can be waste asphalt and rubber, or other raw materials that need to be ground and crushed.
[0023] based on Figures 5 to 8 As shown in the structure, the tool 42 can be constructed in two ways, one of which is as follows: Figure 5 and Figure 6 As shown, the cutting tool 42 is a triangular block, and the cutting tool 42 is detachably connected to the grinding rod body 43. This detachable connection can be achieved by using a detachable structure such as bolts, as shown in the figure.
[0024] Another way is, such as Figure 7 and Figure 8 As shown, the cutting tool 42 is a triangular blade. The cutting tool 42 is detachably connected to the grinding rod 43. This detachable connection can be achieved by using bolts, as shown in the figure. It is necessary to ensure that the blade thickness at the bolt connection meets the corresponding standard, that is, several sets of thicker blades are needed for proper fit.
[0025] Furthermore, such as Figure 9 and Figure 10 As shown, in order to better adjust the grinding rod 43, the following configuration is adopted: the surface of the triangular blade is provided with a recessed groove 44, the grinding rod 43 is housed in the recessed groove 44, and the grinding rod 43 is detachably connected to the moving end of the telescopic structure. The telescopic structure extends, causing the grinding rod 43 to extend out of the recessed groove 44. The fixed end of the telescopic structure is fixedly connected to the rotating shaft 54. In this configuration of the blade 42, the blade 42 is not detachably connected to the grinding rod 43.
[0026] Furthermore, the telescopic structure includes an outer tube 431 with an opening at its upper end. An inner rod 432 is inserted into the upper end of the outer tube 431. A limiting block is fixedly connected inside the outer tube 431. A sliding block is provided at the lower end of the inner rod 432. A spring assembly 433 is fixedly connected to the lower end of the sliding block. When the grinding rod 43 moves away from the recess 44 to its limit position, the sliding block contacts the limiting block, and the spring in the spring assembly 433 is stretched. In this design, a certain plate can be provided inside to assist in the installation of the spring assembly 433.
[0027] Furthermore, the rotating shaft 54 is a hollow structure with one end open. An air pump assembly 6 is also connected inside the frame structure 1. The output end of the air pump assembly 6 is connected to a coupling assembly 61. The air pump assembly 6 is connected to the rotating shaft 54 through the coupling assembly 61. The outer tube 431 communicates with the interior of the rotating shaft 54. An elastic layer is provided on the edge of the sliding block. The sliding block is tightly connected to the inner wall of the outer tube 431 through the elastic layer. In this scheme, the bottom of the spring in the spring assembly 433 is connected to the surface of the rotating shaft 54.
[0028] Further, the triangular blade type cutter 42 is composed of three groups of single pieces, the surface of the single piece is provided with a through hole 434, a group of outer tubes 431 is arranged between two groups of cutters 42, the outer tube 431 is connected with a movable clamping column 435, the clamping column 435 is inserted into the through hole 434 to fix the single piece. The three groups of single pieces are used to form a group of cutters 42, which is convenient for replacement after damage.
[0029] Further, the outer surface of the outer tube 431 is provided with an isolation cavity 438, the clamping column 435 of a group of outer tubes 431 is inserted into the isolation cavity 438 of the adjacent outer tube 431, the lower end surface of the insertion end of the clamping column 435 is provided with a wedge surface, the other end of the clamping column 435 is provided with an elastic block, the outer tube 431 is fixedly connected with a sliding tube 436, the elastic block tightly slides on the inner wall of the sliding tube 436, and the end surface of the sliding tube 436 is also fixedly connected with a communication tube 437. In actual use, the clamping column 435 penetrates the through hole 434 on the surface of the single piece and is inserted into the isolation cavity 438. When it needs to be disassembled, the air pump assembly 6 is used for air extraction treatment, the elastic block drives the clamping column 435 to slide in the sliding tube 436, so that the wedge surface on the surface of the clamping column 435 corresponds to the position of the through hole 434 on the surface of the single piece. At this time, the single piece is in a movable state. If it needs to be replaced, it can be pulled directly upwards to extract the single piece.
[0030] It should be further explained that the driving device 5 comprises a rotating motor, the output shaft of the rotating motor is fixedly connected with a driving wheel 51, one end of the rotating shaft 54 is fixedly connected with a rotating wheel 53, and the driving wheel 51 and the rotating wheel 53 are connected through a driving chain 52. In this embodiment, the rotating motor is a stepping motor, which refers to an electric motor that converts electrical pulses into angular displacement to control the rotation of the rotor. It is used as an execution element in automatic control devices. Every time a pulse signal is input, the stepping motor moves forward by one step, so it is also called a pulse motor. Stepping motors are commonly used in external devices of digital computers, printers, plotters, disk devices, etc. The driving power source of the stepping motor is composed of a variable frequency pulse signal source, a pulse distributor and a pulse amplifier. The driving power source provides pulse current to the motor winding. The running performance of the stepping motor depends on the good cooperation between the motor and the driving power source. The advantages of the stepping motor are no cumulative error, simple structure, convenient use and maintenance, and low manufacturing cost.
