DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] A construction waste recycling device for construction projects, such as Figure 1-Figure 4 As shown, it includes a frame 1, a crushing bin 101, a drive box 102, a crushing roller 103, a conveying mechanism and a crushing mechanism. The crushing bin 101 is connected to the top of the frame 1, and the drive box 102 is installed on the left side of the crushing bin 101. The drive box 102 is provided with two spiral feeding shafts 206. The front and rear sides of the crushing bin 101 are rotatably connected. The left sides of the two crushing rollers 103 are respectively connected to the two spiral feeding shafts 206 of the drive box 102, so that the drive box 102 can drive the two crushing rollers 103 to rotate, so as to achieve the effect of crushing the construction waste. The crushing bin 101 is provided with a conveying mechanism, and the conveying mechanism is provided with a crushing mechanism.

[0023] like Figure 3 and Figure 4 As shown, the conveying mechanism includes a transmission cylinder 2, a motor 201, a discharge pipe 202, a spiral feeding shaft 206 and a transmission assembly. The bottom of the crushing bin 101 is connected to the transmission cylinder 2, and the spiral feeding shaft 206 is rotatably connected inside the transmission cylinder 2. A discharge pipe 202 is opened at the lower right side of the transmission cylinder 2, and a motor 201 is installed on the top right side of the transmission cylinder 2. A transmission assembly is provided between the output shaft of the motor 201 and the spiral feeding shaft 206.

[0024] like Figure 3As shown, the transmission assembly includes a pulley 1 203, a flat belt 204 and a pulley 2 205. The output shaft of the motor 201 is connected to the pulley 1 203, and the right side of the spiral feeding shaft 206 is connected to the pulley 2 205. A flat belt 204 is wound between the pulley 2 205 and the pulley 1 203. The operation of the motor 201 can drive the spiral feeding shaft 206 to rotate through the transmission of the pulley 1 203, the pulley 2 205 and the flat belt 204, so that the spiral feeding shaft 206 can transport the material in the transmission cylinder 2.

[0025] like Figure 4 As shown, the crushing mechanism includes a vibration roller 3, a slide bar 301 and a spring 303. A plurality of groups of slide bars 301 are slidably connected to the spiral feed shaft 206 at uniform intervals along the circumferential direction. Each group of slide bars 301 is provided with two and are symmetrically distributed on the left and right. A vibration roller 3 is installed between the two slide bars 301 in each group. A spring 303 is connected between the slide bar 301 and the spiral feed shaft 206. A notch is provided in the spiral part of the spiral feed shaft 206. The vibration roller 3 is located in the notch and can vibrate in the notch to prevent the threaded part of the spiral feed shaft 206 from hindering the operation of the vibration roller 3.

[0026] When construction waste needs to be recycled, this equipment can be used. When in use, the construction waste is first put into the crushing bin 101, and then the drive box 102 is controlled to drive the two crushing rollers 103 to rotate to crush the construction waste. The crushed construction waste falls into the transmission drum 2. At this time, the motor 201 can be controlled to operate through the pulley 1 203, the flat belt 204 and the pulley 2 205 to drive the spiral feeding shaft 206 to rotate. The spiral feeding shaft 206 can transport the construction waste in the transmission drum 2 when rotating. In the process of transportation, the vibration roller 3 can be controlled to vibrate and knock the construction waste. The spring 1 303 plays a buffering role. When the vibration roller 3 knocks the construction waste, it can crush the concrete on the surface of the steel bar, so that the concrete is separated from the steel bar. The crushed construction waste can be discharged through the discharge pipe 202. In this way, this equipment can be used to process construction waste, and in the process of processing, the concrete in the steel bar can be crushed to achieve the effect of separating the steel bar and concrete.

[0027] like Figure 5-Figure 7As shown, it also includes a blanking mechanism, which includes an I-shaped rod 4, a spring 2 401, a sliding sleeve 403, a convex ring 404, a baffle 5 and a connecting rod 501. The right side of the frame 1 is connected to the sliding sleeve 403, and the I-shaped rod 4 is slidably connected in the sliding sleeve 403. The I-shaped rod 4 can slide up and down along the sliding sleeve 403. Four springs 2 401 are connected between the I-shaped rod 4 and the transmission cylinder 2. Two convex rings 404 are connected to the right side of the crushing roller 103. The upper part of the I-shaped rod 4 is located at the convex ring 404. The moving trajectory of the starting position is arranged so that the convex ring 404 can squeeze the I-shaped rod 4 to move through the convex position on it when rotating. The lower parts of the front and rear sides of the crushing chamber 101 are rotatably connected with baffles 5, and the baffles 5 are connected to the connecting rod 501. Two inclined grooves are provided on the right side of the crushing chamber 101, and a straight groove is provided on the front and rear sides of the lower part of the I-shaped rod 4. The connecting rod 501 is slidably connected to the inclined groove, and the right end of the connecting rod 501 is inserted into the straight groove, so that the I-shaped rod 4 can squeeze the connecting rod 501 to move when it moves downward.

[0028] After the crushing roller 103 crushes the construction waste, the baffle 5 can block the construction waste, and when the crushing roller 103 rotates, it can drive the convex ring 404 to rotate. When the convex ring 404 rotates, the raised position on it can rotate to contact the I-shaped rod 4. At this time, the convex ring 404 continues to rotate to squeeze the I-shaped rod 4 to move downward. The spring 2 401 is compressed, and the I-shaped rod 4 can drive the two connecting rods 501 to move downward when it moves downward. The connecting rod 501 can be expanded through the inclined slot when it moves downward, thereby driving the two baffles 5 to open and no longer block the construction waste. At this time, the construction waste can fall, and when the convex ring 404 rotates to disengage from the I-shaped rod 4, the I-shaped rod 4 is reset under the action of the spring 2 401, thereby driving the baffle 5 to reset through the connecting rod 501. Repeating this process can achieve intermittent unloading, thereby avoiding blockage caused by all materials being added to the transmission cylinder 2 at one time.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
