[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] This utility model discloses a waste mortar recycling and sorting device, which mainly includes a frame 1, a mounting base 2, a sorting box 3, a screen 4, a discharge hopper 5, a transmission mechanism 6, and a brush plate 7. The mounting base 2 is installed on the top of the frame 1, the sorting box 3 is slidably installed on the mounting base 2, the screen 4 is installed inside the sorting box 3, the discharge hopper 5 is installed at the bottom of the sorting box 3, and a discharge trough 302 communicating with the top surface of the screen 4 is provided on the side. A first straight groove 301 is opened on the side wall of the sorting box 3, and a second straight groove 202 is opened on the mounting base 2. A connecting rod 701 is provided at the end of the brush plate 7. The end of the connecting rod 701 passes through the first straight groove 301 on the sorting box 3 and is slidably installed in the second straight groove 202 of the mounting base 2 through a slider. Elastic brushes that contact the bottom of the screen 4 are evenly arranged on the brush plate 7. The transmission mechanism 6 is installed on the mounting base 2 and is connected to the connecting rod 701 on the brush plate 7 and the sorting box 3.

[0019] In use, the waste mortar to be sorted is poured into the sorting box 3, and the transmission mechanism 6 is started to drive the brush plate 7 and the sorting box 3 to work. The sorting box 3 slides back and forth on the mounting base 2, driving the screen 4 to move back and forth, thereby screening the waste mortar. Smaller particles fall through the screen 4 into the discharge hopper 5 and are discharged from the bottom of the discharge hopper 5 into the collection box for subsequent processing or reuse. Larger impurities and lumps remain on the screen 4 and are gradually discharged along the discharge chute 302 during the screening process. At the same time, the brush plate 7 moves along the transmission mechanism. Driven by the mechanism 6, it moves back and forth along the bottom of the screen 4. The elastic brush on the brush plate 7 contacts the bottom of the screen 4, brushing away the impurities and large particles attached to the screen 4, ensuring the screen is unobstructed and improving the cleaning effect. The brushed-off impurities and large particles are discharged from the sorting box 3 through the discharge chute 302. In the whole process, the coordinated work of the brush plate 7 and the sorting box 3 realizes the function of screening and cleaning at the same time, reducing the possibility of screen 4 clogging and improving the sorting efficiency and cleaning effect of waste mortar.

[0020] The transmission mechanism 6 includes a motor 601, a rotating shaft 602, a crankshaft 603, a driving gear 604, a driven gear 605, a first connecting rod 606, a crank 607, and a second connecting rod 608. The rotating shaft 602 and crankshaft 603 are both mounted on the mounting base 2 via bearings. The motor 601 is mounted on the frame 1 and is connected to the rotating shaft 602 via a belt drive mechanism. A crank 607 is mounted at the end of the rotating shaft 602, and the crank 607 is connected to the end of the connecting rod 701 via the second connecting rod 608. The driving gear 604 is mounted on the rotating shaft 602, and the driven gear 605, which meshes with the driving gear 604, is mounted on the crankshaft 603. One end of the first connecting rod 606 is hinged to the crankshaft 603, and the other end is hinged to the side wall of the sorting box 3. When the motor 601 is started, the motor 601 drives the rotating shaft 602 to rotate via the belt drive mechanism. The rotating shaft 602 rotates via the driving gear 604 and the driven gear 605. The crankshaft 603 is driven to rotate, and the crankshaft 603 drives the sorting box 3 to slide back and forth on the mounting base 2 through the first connecting rod 606, so that the screen 4 screens the waste mortar. At the same time, the crank 607 at the end of the rotating shaft 602 is connected to the connecting rod 701 on the brush plate 7 through the second connecting rod 608, thereby driving the brush plate 7 to move back and forth along the bottom of the screen 4, brushing away impurities and large particles on the surface of the screen 4. The transmission mechanism 6 enables the brush plate 7 and the sorting box 3 to work together, improving the sorting efficiency and cleaning effect of waste mortar, while also reducing the possibility of screen clogging.

[0021] The mounting base 2 is equipped with a support base 201, and the support base 201 has a guide groove 2011. The side wall of the sorting box 3 is provided with a support rod 303, which passes through the guide groove 2011 on the support base 201 and is slidably connected to it. The support base 201 can provide support and guidance for the sorting box 3, ensuring that the sorting box 3 remains stable during the reciprocating sliding process.

[0022] Work process:

[0023] In use, the waste mortar to be sorted is poured into the sorting box 3, and the motor 601 is started. The motor 601 drives the rotating shaft 602 to rotate through the belt drive mechanism. The rotating shaft 602 drives the crankshaft 603 to rotate through the driving gear 604 and the driven gear 605. The crankshaft 603 drives the sorting box 3 to slide back and forth on the mounting base 2 through the first connecting rod 606, so that the screen 4 moves back and forth, thereby screening the waste mortar. Smaller particles fall into the discharge hopper 5 through the screen 4 and are discharged from the bottom of the discharge hopper 5 into the collection box for subsequent processing or reuse. Larger impurities and lumps remain on the screen 4 and are gradually discharged along the discharge chute 302 during the screening process. At the same time, the crank 607 at the end of the rotating shaft 602 drives the crank 603 through the second connecting rod 608. The brush plate 7 is connected to the connecting rod 701 on the brush plate 7, thereby driving the brush plate 7 to move back and forth along the bottom of the screen 4, brushing away impurities and large particles on the surface of the screen 4, ensuring the screen is unobstructed and improving the cleaning effect. The brushed-off impurities and large particles are discharged from the sorting box 3 through the discharge chute 302. During the entire working process, the transmission mechanism 6 enables the brush plate 7 and the sorting box 3 to work together, realizing the function of screening and cleaning at the same time, improving the sorting efficiency and cleaning effect of waste mortar, and also reducing the possibility of screen 4 clogging.
