Description

Technical Field

[0001] This utility model relates to the technical field of solid waste treatment mechanisms, and in particular to a fixed waste disposal device. Background Technology

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, daily life and other activities. It mainly includes solid particles, garbage, slag, sludge, discarded products, broken utensils, etc. If a large amount of solid waste is generated in daily life and is not effectively treated, it will occupy a lot of space, waste resources, and cause significant pollution to the environment.

[0003] Chinese Patent No. CN219308836U discloses a device for the harmless disposal of solid waste, relating to the technical field of solid waste treatment mechanisms. The technical solution includes a disposal box with a feeding port on its top wall that communicates with the inner cavity of the box. Rotating shafts are rotatably connected to both sides of the inner cavity of the feeding port. Crushing rollers are fixedly mounted on the surface of the rotating shafts. Driven by a transmission mechanism, a screening box and a filter screen vibrate back and forth, achieving a screening and filtering effect. This enables the screening and filtering of crushed solid waste, facilitating the removal of larger waste items for secondary crushing, thus giving the solid waste disposal device a screening and filtering function.

[0004] However, the above technical solution has the following shortcomings: when using the device to perform secondary crushing of larger waste, the user needs to manually pick out the larger waste, and some waste contains substances that are harmful to the human body, which increases the probability of the waste causing harm to the human body. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a fixed waste disposal device that automatically reprocesses waste by using a drive component to rotate a ring, allowing multiple collection troughs to transport larger waste particles back to the crushing component.

[0006] The technical solution of this utility model is a fixed waste disposal device, comprising: a frame on which an arc-shaped frame is provided; a crushing and screening mechanism, comprising a crushing component and a screening component provided on the frame and the arc-shaped frame; a return component, comprising a ring, a plurality of rollers uniformly rotatably arranged on the outer circumference of the ring, and a drive component drivenly connected to the ring; and a plurality of receiving troughs uniformly distributed along the ring on the inner circumference of the ring.

[0007] Preferably, the crushing assembly includes a mounting plate mounted on a frame, a motor a mounted on the mounting plate, gears a and b meshing and rotating on the mounting plate and the frame, and two crushing rollers rotating on the frame; the two crushing rollers are coaxially connected to gears a and b respectively.

[0008] Preferably, the screening assembly includes multiple placement racks arranged side by side on the frame, multiple pistons evenly arranged on the multiple placement racks, multiple motors b arranged on the frame, multiple eccentric rollers evenly arranged at the output end of the motors b, and a screening plate arranged on multiple sets of vibrating assemblies; the placement racks and the multiple motors b are distributed in a one-to-one correspondence.

[0009] Preferably, the frame is also equipped with a guide frame, and the bottom of the guide frame is equipped with multiple sets of vibration components.

[0010] Preferably, the tops of the screening plate and the guide frame are inclined from both ends toward the middle.

[0011] Preferably, the cross-sectional area of ​​the receiving trough gradually decreases from the inner circumference of the ring to the outer circumference and then gradually increases.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In operation, waste is first processed by crushing and screening components. Waste that meets the screening requirements is discharged. Larger particles slide into the receiving chute and move to the crushing components for secondary crushing. The crushed waste is then conveyed back to the screening components by guide blocks for further screening, achieving automated processing and reducing the risk of user exposure to contaminants.

[0018] Example 1

[0019] like Figures 1-3 As shown, this embodiment proposes a fixed waste disposal device, including a frame 1, a crushing and screening mechanism, and a return material assembly 8. An arc-shaped frame 2 is mounted on the frame 1. The crushing and screening mechanism includes a crushing assembly mounted on the frame 1 and the arc-shaped frame 2, and a screening assembly mounted on the frame 1 and the arc-shaped frame 2. The return material assembly 8 includes a circular ring 81, multiple rollers 82 evenly rotatably arranged on the outer circumference of the circular ring 81, and a drive assembly driven by the circular ring 81. The drive assembly is a conventional motor and gear transmission, and the outer circumference of the circular ring 81 has a gear section. Multiple collection troughs 811 are evenly distributed along the inner circumference of the circular ring 81. The cross-sectional area of ​​the collection troughs 811 gradually decreases and then gradually increases from the inner circumference to the outer circumference of the circular ring 81, making it difficult for larger particles falling into the collection troughs 811 to roll out until the collection troughs 811 move above the crushing assembly.

[0020] In this embodiment, waste falls sequentially onto the crushing component and the screening component. The screening component discharges waste that meets the processing requirements, and then allows larger waste particles to slide into the receiving trough 811 at the ring 81. After the receiving trough 811 moves above the crushing component, the crushing component performs secondary crushing on the waste. The guide block 16 on the arc frame 2 transports the secondary crushed waste to the screening component for further screening, thereby achieving automatic processing of larger waste and reducing the probability of users being contaminated by pollutants in the waste.

[0021] Example 2

[0022] like Figure 1 and Figure 2 As shown, the fixed waste disposal device proposed in this embodiment, compared with the first embodiment, includes a crushing component comprising a mounting plate 3 mounted on a frame 1, a motor a4 mounted on the mounting plate 3, gears a5 and b6 meshing and rotating on the mounting plate 3 and the frame 1, and two crushing rollers 7 rotating on the frame 1; the two crushing rollers 7 are coaxially connected to gears a5 and b6 respectively.

[0023] The screening assembly includes multiple placement racks 9 arranged side by side on the frame 1, multiple pistons 10 evenly arranged on the multiple placement racks 9, multiple motors b11 arranged on the frame 1, multiple eccentric rollers 12 evenly arranged at the output end of the motors b11, and screening plates 13 arranged on multiple sets of vibrating assemblies; the placement racks 9 and the multiple motors b11 are distributed in a one-to-one correspondence.

[0024] In this embodiment, motor a4 drives gear a5 to rotate, and gear a5 drives gear b6 to rotate through meshing. Gears a5 and b6 drive two crushing rollers 7 to rotate relative to each other, thereby crushing the waste. Then, piston 10 and multiple eccentric rollers 12 are proportionally reduced in size according to the tilt angle of the screening plate 13, as the screening plate 13 tilts downward, thus ensuring the stability of the up and down movement of the screening plate 13. It is optimal to set two motors b11 and two placement frames 9. Multiple pistons 10 are in contact with the edge of the screening plate 13 to reduce the impact on screening.

[0025] Example 3

[0026] like Figure 1 and Figure 2 As shown in the figure, the fixed waste disposal device proposed in this embodiment, compared with the first embodiment, has a guide frame 14 on the frame 1, and multiple sets of vibration components 15 are provided at the bottom of the guide frame 14. The top of both the screening plate 13 and the guide frame 14 are inclined from both ends towards the middle.

[0027] In this embodiment, the waste falling onto the screening plate 13 and the guide frame 14 will gradually slide towards the center and downwards under the action of vibration, thereby preventing the waste from rolling out from both sides of the guide frame 14 and the screening plate 13.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
