[0035] Please see Figures 1-5 This application provides a new technical solution: a waste crusher, including a crushing chamber 2 for crushing waste, a feeding chamber 3 above the crushing chamber 2 for adding waste to be processed into the crushing chamber 2 through the feeding chamber 3, a screening chamber 1 below the crushing chamber 2, and a discharge port 14 on one side of the screening chamber 1 for discharging the crushed waste.
[0036] The crushing chamber 2 is provided with a first crushing blade group 10 and a second crushing blade group 11. There are two sets of each of the first crushing blade group 10 and the second crushing blade group 11, and the two sets of the first crushing blade group 10 and the second crushing blade group 11 rotate relative to each other inside the crushing chamber 2.
[0037] Two sets of first crushing blade groups 10 are located below the feeding bin 3, and two sets of second crushing blade groups 11 are located below the two sets of first crushing blade groups 10. The gap between the two sets of second crushing blade groups 11 is smaller than the gap between the two sets of first crushing blade groups 10, which is used to finely crush the waste.
[0038] In use, waste is added to the crushing chamber 2 through the feeding hopper 3. The first crushing blade group 10 and the second crushing blade group 11 are located at different heights below the feeding hopper. The first crushing blade group is responsible for initial crushing, while the second crushing blade group further refines the crushed waste. The material after two-stage crushing falls into the screening chamber 1 and is discharged through the discharge port 14. The graded crushing design improves crushing efficiency and ensures that waste of different sizes can be effectively processed. The relatively rotating crushing blade group can better control the crushing force and reduce the generation of excessively large or small particles.
[0039] In some embodiments, a gearbox 6 is provided on one side of both the first crusher group 10 and the second crusher group 11 for driving the two groups of the first crusher group 10 and the second crusher group 11 to rotate relative to each other. A first gear 62 and a second gear 63 are rotatably arranged inside the gearbox 6, and the first gear 62 and the second gear 63 are meshed together.
[0040] In this embodiment, the first gear 62 and the second gear 63 are respectively connected to two sets of the first crushing blade group 10 or the second crushing blade group 11. A second motor 61 is provided on one side of the first gear 62 or the second gear 63 to drive the first gear 62 and the second gear 63 to rotate relative to each other, so that the two sets of the first crushing blade group 10 or the two sets of the second crushing blade group 11 rotate relative to each other.
[0041] In use, the second motor 61 is connected to one of the gears. When the motor starts, it drives the entire gear set to run. The first gear 62 and the second gear 63 inside mesh with each other, so that the two crushing blade sets can rotate relative to each other.
[0042] In some embodiments, two dispersing rods 12 are provided below the two sets of second crushing blade groups 11. A transmission box 7 is connected to one side of the two dispersing rods 12. The transmission box 7 drives the two dispersing rods 12 to rotate inside the screening chamber 1, which is used to disperse the crushed waste in the crushing chamber 2. The two dispersing rods 12 are provided below the second crushing blade groups. They are driven by the transmission box 7 and rotate synchronously in the screening chamber to help to evenly distribute the crushed material. The dispersing rods help to prevent material accumulation, promote the smooth progress of the subsequent screening process, improve screening efficiency, and reduce the possibility of clogging.
[0043] In some embodiments, the two transmission boxes 7 are respectively connected to the first transmission wheel 72 and the second transmission wheel 73. The first transmission wheel 72 and the second transmission wheel 73 are connected by a rotating belt 74 to drive the first transmission wheel 72 and the second transmission wheel 73 to rotate synchronously.
[0044] In some embodiments, a third motor 71 is provided on one side of the first transmission wheel 72 or the second transmission wheel 73 to drive the first transmission wheel 72 or the second transmission wheel 73 on one side to rotate synchronously under the drive of the rotating belt 74, so that the two dispersion rods 12 rotate synchronously.
[0045] When in use, the third motor 71 is started, which drives a transmission wheel to rotate. The first transmission wheel 72 and the second transmission wheel 73 are connected by a rotating belt 74, which ensures that the two dispersing rods 12 move synchronously, ensuring consistency between the dispersing rods and avoiding uneven material distribution caused by asynchrony.
[0046] In some embodiments, a screening plate 13 is inclinedly arranged below the two dispersing rods 12. One side of the screening plate 13 is rotatably arranged on the inner wall of the screening chamber 1. A cam 81 is arranged below the middle of the screening plate 13 to push the screening plate 13 to rotate around one side of the screening chamber 1. A reciprocating mechanism 9 is arranged below the other side of the screening plate 13 to move the other side of the screening plate 13 up and down inside the screening chamber 1. The screening plate 13 is inclined, and one end of it is pushed by the cam 81 to swing around a fixed point. The other end moves up and down by means of the reciprocating mechanism 9, thereby screening out small particles of waste that meet the requirements. Dynamic screening increases the effective screening area and improves the screening accuracy.
[0047] In some embodiments, a fourth motor 8 is provided on one side of the cam 81 for driving the cam 81 to rotate;
[0048] The reciprocating mechanism 9 includes an installation sleeve 92, which is fixedly installed on the inner wall of the screening chamber 1. A slide rod 91 is slidably sleeved inside the installation sleeve 92. One end of the slide rod 91 is fixedly connected to the bottom of the screening plate 13, and a return spring 93 is sleeved on the other end of the slide rod 91. A limit plate 94 is provided at the other end of the slide rod 91, and the return spring 93 is fixedly installed between the installation sleeve 92 and the limit plate 94.
[0049] In use, the fourth motor 8 drives the cam 81 to rotate, periodically applying a thrust to one side of the screening plate 13, while the slide bar 91 in the reciprocating mechanism moves up and down on the other side under the action of the return spring 93.
[0050] In some embodiments, a screw conveyor 5 is provided on one side of the crusher. The screw conveyor 5 is used to transport the crushed waste screened inside the screening bin 1 to the feeding bin 3 for secondary crushing. A rotating shaft 51 is rotatably connected inside the screw conveyor 5. A spiral fan blade 52 is provided on the rotating shaft 51 to drive the waste conveying. A first motor 4 is provided above the screw conveyor 5 to drive the rotating shaft 51 to rotate. The screw conveyor 5 receives large pieces of incompletely crushed waste from the screening bin 1 and sends them back to the feeding bin 3 for secondary crushing through the spiral fan blade 52.
[0051] In some embodiments, the screw conveyor 5 has an inlet 15 and an outlet 16 on its upper and lower sides, respectively. The inlet 15 is connected to the interior of the screening chamber 1. The other side of the screening plate 13 moves up and down within the inlet 15. The outlet 16 is connected to the interior of the feeding chamber 3. The feeding chamber 3 is equipped with a partition 31, which is rotatably connected to the top of the feeding chamber 3 to separate the inlet and outlet 16 of the feeding chamber 3. The partition 31 inside the feeding chamber 3 can rotate at the top to separate newly added waste from the material to be crushed again returned from the screw conveyor. The presence of the partition prevents the two materials from mixing and ensures the effect of the initial crushing.
[0052] In the operation of a waste crusher, waste is fed into the crushing chamber 2 through the feeding hopper 3. The first crushing blade group 10 is located below the feeding hopper and is responsible for the initial crushing of the waste. The waste that has been initially crushed falls into the area of the second crushing blade group 11 for further crushing to ensure that the waste reaches the required particle size. The crushed material is synchronously rotated in the screening chamber 1 by two dispersing rods 12 to help distribute the material evenly. The screening plate 13 achieves dynamic screening under the action of the cam 81 and the reciprocating mechanism 9, screening out small particles of waste that meet the requirements and discharging them through the discharge port 14. For large pieces of waste that fail to pass the screening, the screw conveyor 5 sends them back to the feeding hopper 3 for secondary crushing until they reach the qualified particle size.
