[0033] like Figures 1 to 4 As shown, a stale garbage vibration screening equipment includes a box body 1, a mounting box 3 is fixedly connected to the top of the box body 1, a screening component 2 is provided in the inner cavity of the mounting box 3, and the screening component 2 includes a motor 2.1, the motor 2.1 is fixedly connected to the bottom of the inner cavity of the mounting box 3, the output end of the motor 2.1 is fixedly connected to a driving bevel gear 2.2, the top of the driving bevel gear 2.2 is meshedly connected to the driven bevel gear 1 2.3, the top of the driven bevel gear 1 2.3 is rotatably connected to the top of the inner cavity of the mounting box 3, the bottom of the driven bevel gear 1 2.3 is fixedly connected to a screening shaft 2.8, the bottom of the driving bevel gear 2.2 is meshedly connected to the driven bevel gear 2 2.4, the bottom of the driven bevel gear 2 2.4 is rotatably connected to the bottom of the inner cavity of the mounting box 3, the bottom of the driven bevel gear 2 2.4 is fixedly connected to a screening drum 2.5, the screening shaft 2.8 is slidably connected to the inner cavity of the screening drum 2.5, and the screening drum 2.5 passes through the top of the box body 1 to the inner cavity.

[0034] In the specific application of the embodiment of the present utility model, when working, the motor 2.1 is started, and the active bevel gear 2.2 at its output end rotates accordingly. The rotation of the active bevel gear 2.2 drives the driven bevel gear 1 2.3 and the driven bevel gear 2 2.4 meshing with it to rotate respectively. When the driven bevel gear 1 2.3 rotates, it drives the screening shaft 2.8 fixed to it to rotate, and the screening shaft 2.8 slides in the inner cavity of the screening drum 2.5. The vibration generated by its rotation is transmitted to the screening drum 2.5, prompting the screening drum 2.5 to vibrate, thereby screening the garbage.

[0035] At the same time, the rotation of driven bevel gear 2.4 directly drives the rotation of screening drum 2.5. The combined rotation and vibration of screening drum 2.5 more effectively screens the garbage, accurately separating materials of different particle sizes. The bottom of screening drum 2.5 penetrates the top of housing 1 and enters the inner cavity of housing 1. The screened material smoothly falls into the inner cavity of housing 1, achieving material collection and separation.

[0036] In one possible embodiment, a screening component 2 6 is provided on the upper part of the inner cavity of the screening shaft 2.8, purifiers 11 are symmetrically fixedly connected to the two side walls of the inner cavity of the box body 1, a collection trough 9 is fixedly connected to the bottom of the box body 1, a discharge port 10 is fixedly connected to the bottom of the collection trough 9, a through groove 7 is opened between the box body 1 and the collection trough 9, a filter screen plate 8 is fixedly connected to the inner cavity of the through groove 7, a sealing door 12 is provided on one side of the box body 1, and a support leg 15 is fixedly connected to the bottom of the box body 1.

[0037] In the specific application of the embodiment of the present invention, after the equipment is started, stale garbage enters from the top entrance of the box body 1. A screening shaft 2.8 is installed inside the box body 1. The rotation of the screening shaft 2.8 drives the screening component 2 6 to vibrate and screen, separating large particles from fine particles in the garbage. The screening component 2 6 is located at the upper part of the inner cavity of the screening shaft 2.8, which can more effectively perform preliminary screening on the incoming garbage.

[0038] The purifiers 11, symmetrically fixed on both sides of the inner cavity of the box body 1, can purify the dust and harmful gases generated during the screening process to ensure the environmental friendliness of the equipment operation. The purifiers 11 reduce the impact on the environment through adsorption, filtration, and other methods. The screened material falls into the aggregate trough 9. The discharge port 10 at the bottom of the aggregate trough 9 is used to discharge the material. A filter screen 8 is fixed in the through groove 7 between the aggregate trough 9 and the box body 1. It further screens fine particles to ensure the purity of the material. The through groove 7 allows the material to smoothly transition from the box body 1 to the aggregate trough 9, and the filter screen 8 plays a role of secondary filtration.

[0039] The sealed door 12 on one side of the box body 1 facilitates maintenance and overhaul of the equipment while maintaining internal sealing to prevent dust leakage. The legs 15 at the bottom of the box body 1 provide firm support for the equipment, ensuring the stability of the equipment during operation.

[0040] In one possible embodiment, a plurality of screening rods 2.6 are evenly fixedly connected to the side wall of the screening drum 2.5, a plurality of screening blades 2.7 are evenly fixedly connected to the side wall of the screening rod 2.6, a screening shaft 2.8 is longer than the screening drum 2.5, and the screening shaft 2.8 passes through the lower part of the side wall of the screening drum 2.5 and is evenly fixedly connected to a plurality of screening blades 2.9, and a plurality of through holes 2.10 are evenly opened on the screening blades 2.9.

[0041] In the specific application of the embodiment of the present utility model, the screening shaft 2.8 starts to rotate under the drive of the motor. Since the screening shaft 2.8 is longer than the screening drum 2.5, and a number of screening blades 2.9 are evenly fixedly connected to its lower part, and a number of through holes 2.10 are evenly opened on the screening blades 2.9, when the screening shaft rotates, it drives the screening blades 2.9 to rotate, thereby stirring and pushing the stale garbage entering the screening drum 2.5.

[0042] Several screening rods 2.6 are evenly fixedly attached to the sidewalls of the screening drum 2.5. Several screening blades 2.7 are evenly fixedly attached to these rods 2.6. The rotation and vibration of the screening shaft further separate and sift the stale waste. Smaller particles or materials meeting the requirements fall through the through-holes 2.10 in the screening blades 2.7 and screening blades 2.9, and are collected as undersize. Larger materials remain in the screening drum 2.5 for further screening or discharge through the equipment's outlet.

[0043] In one possible embodiment, the screening component 2 6 includes a two-phase motor 6.1, which is fixedly connected to the upper part of the inner cavity of the screening shaft 2.8. The two output ends of the two-phase motor 6.1 are fixedly connected to the rotating shaft 6.2, and the rotating shaft 6.2 slides through the screening shaft 2.8 to the outside. One end of the rotating shaft 6.2 is fixedly connected to the screening rod 2 6.3, and a number of screening leaves 2 6.4 are evenly fixedly connected to the side walls of the screening rod 2 6.3. The screening blade 2 6.5 is fixedly sleeved on the screening leaf 2 6.4.

[0044] In the specific application of the embodiment of the present invention, a two-phase motor 6.1 is fixedly mounted on the upper portion of the inner cavity of the screening shaft 2.8, with its two output ends respectively connected to a rotating shaft 6.2. The two rotating shafts 6.2 are able to slide along the centerline of the screening shaft 2.8 and extend to the outside. When the two-phase motor 6.1 is started, it drives the rotating shaft 6.2 to rotate. One end of the rotating shaft 6.2 is fixedly connected to the second screening rod 6.3, which means that the second screening rod 6.3 rotates with the rotation of the rotating shaft 6.2.

[0045] A number of screening blades 6.4 are evenly and fixedly connected to the side walls of the screening rod 6.3. When the screening blades 6.4 rotate, they stir and push the garbage through the screening shaft 2.8. When the screening blades 6.5 rotate, the garbage on them will be affected by centrifugal force. Small garbage particles will fall through the gaps between the screening blades 6.5, while larger garbage particles will be continuously pushed until they are discharged through the outlet of the equipment.

[0046] The rotation of the two-phase motor 6.1 is transmitted to the second screening rod 6.3 through the rotating shaft 6.2, and then the second screening leaf 6.4 and the second screening blade 6.5 are used to screen the garbage, effectively achieving fine screening and grading of stale garbage, thereby improving the efficiency and quality of garbage treatment.

[0047] In one possible embodiment, an exhaust valve 4 is provided on one side of the top of the box body 1, a temperature and pressure detector 5 is provided on one side of the top of the box body 1, an observation window 13 is provided on one side of the sealed door 12, a door handle 14 is fixedly connected to one side of the sealed door 12, and the door handle 14 is located on one side of the observation window 13.

[0048] In the specific application of the embodiment of the present invention, the exhaust valve 4 is arranged on the top side of the box body 1 to adjust the air pressure inside the box body during the operation of the equipment to prevent the screening efficiency from decreasing or the equipment from being damaged due to uneven air pressure. The exhaust valve 4 can also discharge harmful gases in the box body to keep the working environment clean.

[0049] The temperature and pressure detector 5 monitors the temperature and pressure inside the box in real time, ensuring that the equipment operates within a safe range and preventing equipment failures caused by abnormal temperature or pressure. The sealed door 12 and observation window 13 ensure the tightness of the box 1, preventing the leakage of dust and odor generated during the screening process. Furthermore, the observation window 13 allows the operator to observe the internal operation of the equipment at any time, identify problems, and make adjustments promptly.
