[0003] In existing technologies, the solid waste to be processed is added into the device during use, and the solid waste is crushed by the crushing structure inside the device to achieve environmentally friendly treatment. However, after long-term use, the effect of the crushing wheel will decrease, resulting in the solid waste not being effectively crushed. Some incompletely crushed solid waste will be discharged, affecting the needs of subsequent processing. It is also impossible to quickly separate materials of different particle sizes, increasing the complexity of subsequent processing steps and requiring manual intervention or secondary processing. Therefore, it is necessary to improve the environmentally friendly construction solid waste crushing device to solve the above problems. Utility Model Content

[0013] The beneficial effects of this utility model are:
[0014] 1. Compared to environmentally friendly construction solid waste crushing devices that cannot perform screening, this device uses the rotation of the second rotating shaft to drive the push rod, which in turn drives the sliding limit block outside the limit fixing rod to slide. Through the set reset spring, the support connecting rod pushes the sliding limit block on the reset spring to move up and down, allowing the solid waste to be effectively separated by size.

A second rotating shaft 806 is fixedly connected to the front of the second transmission pulley 804. A push rod 807 is fixedly connected to the outside of the second rotating shaft 806. A support connecting rod 808 is rotatably connected to the outside of the push rod 807. A limit fixing rod 810 is fixedly connected to the top of the support connecting rod 808. A sliding limit block 809 is slidably connected to the outside of the limit fixing rod 810. The filter plate 7 is fixedly connected inside the sliding limit block 809. The feed inlet 6 facilitates the feeding of solid waste into the device. The lifting handle 5 is used to lift the screening box 1 and crushing box 2 for separation and installation. The support base 3 provides structural support. The discharge port 4 facilitates the discharge of processed solid waste. A first motor 801 drives a first transmission pulley 803 on the outside of a first rotating shaft 802. The rotation of the first transmission pulley 803, under the action of the connecting transmission belt 805, drives a second rotating shaft 806 on the outside of a second transmission pulley 804. The rotation of the second rotating shaft 806 drives a push rod 80. 7. Pushing the support connecting rod 808 causes it to drive the sliding limiting block 809 outside the limiting fixing rod 810 to vibrate continuously. The sliding limiting block 809 has a groove at the corresponding position of the limiting fixing rod 810. The limiting fixing rod 810 slides inside the groove. Through the groove opened inside the sliding limiting block 809 at the position of the limiting fixing rod 810, the limiting fixing rod 810 is limited when sliding inside the groove. There are two limiting fixing rods 810, and the two limiting fixing rods 810 are symmetrically fixedly connected to the top of the support connecting rod 808. The two limiting fixing rods 810 make the sliding limiting block 809 more stable when sliding inside the screening box 1.
[0024] Please see Figure 4 - Figure 5 In this embodiment, the screening box 1 has a slot at the position corresponding to the sliding limit block 809. The sliding limit block 809 slides inside the slot.

A return spring 811 is fixedly connected between the support connecting rod 808 and the sliding limit block 809. The return spring 811 causes the support connecting rod 808 to push the sliding limit block 809 on the return spring 811 to move up and down.
[0025] Please see Figure 2 - Figure 3 In this embodiment, the crushing assembly includes a support connecting plate 901, which is fixedly connected to the front of the crushing chamber 2. A second motor 902 is installed inside the support connecting plate 901. A rotating connecting shaft 903 is fixedly connected to the output end of the second motor 902. A first gear 904 is fixedly connected to the outside of the rotating connecting shaft 903. A rotating rod 905 is rotatably connected inside the crushing chamber 2. A second gear 906 is fixedly connected to the outside of the rotating rod 905. A crushing roller 907 is fixedly connected to the outside of the rotating rod 905. An inclined ramp 908 is fixedly connected inside the crushing chamber 2. A nozzle 909 is installed inside the crushing chamber 2. The second motor 902 drives the first gear 904 outside the rotating connecting shaft 903. Inside the crushing chamber 2, the first gear 904 and the second gear 906 mesh to drive two rotating rods 905 to rotate. The rotation of the rotating rods 905 drives two crushing rollers 907 to mesh and rotate, crushing solid waste. The nozzles 909 play a role in dust suppression. There are two rotating rods 905, which are symmetrically connected inside the crushing chamber 2. The two rotating rods 905 enable the crushing rollers 907 to mesh and rotate. There are several nozzles 909, which are evenly distributed inside the crushing chamber 2. The nozzles 909 provide a uniform dust removal effect on the dust generated inside the equipment.
[0026] During operation, solid waste is fed into the equipment through the feed inlet 6. A second motor 902 drives a first gear 904 outside the rotating connecting shaft 903 to rotate inside the crushing chamber 2. The meshing of the first gear 904 and the second gear 906 drives two rotating rods 905 to rotate. The rotation of the rotating rods 905 drives two crushing rollers 907 to mesh and rotate, crushing the solid waste. A nozzle 909 serves to reduce dust. During screening, a first motor 801 drives a first transmission pulley 803 outside the first rotating shaft 802 to rotate. The rotation of the first transmission pulley 803... The transmission belt 805 drives the second rotating shaft 806 outside the second transmission pulley 804 to rotate. The rotation of the second rotating shaft 806 drives the push rod 807 to push the support connecting rod 808, which in turn drives the sliding limit block 809 outside the limit fixing rod 810 to slide. Through the set reset spring 811, the support connecting rod 808 pushes the sliding limit block 809 on the reset spring 811 to move up and down, so as to screen and discharge the screened small solid waste through the discharge port 4. When the screened large stones need to be removed, the lifting handle 5 is pulled to separate the screening box 1 and the crushing box 2, so that the stones on the filter plate 7 can be removed.
[0027] Through the above steps, the rotation of the second rotating shaft 806 drives the push rod 807 to push the support connecting rod 808, causing it to slide the sliding limit block 809 outside the limit fixing rod 810. Through the set reset spring 811, the support connecting rod 808 pushes the sliding limit block 809 on the reset spring 811 to move up and down. This solves the problem that after long-term use of the environmentally friendly construction solid waste crushing device, the effect of the crushing wheel will decrease, which will lead to the solid waste not being effectively crushed. Some incompletely crushed solid waste will be discharged, affecting the needs of subsequent processing, making it impossible to quickly separate materials of different particle sizes, increasing the complexity of subsequent processing steps, and requiring manual intervention or secondary processing.
