Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, and in particular to a double-roller toothed staggered kitchen waste crushing box. Background Technology

[0002] With the acceleration of urbanization, food waste disposal has become an important issue in environmental sanitation management. Food waste crushing devices are usually used to process food waste generated by households or commercial establishments. They mechanically crush food waste into smaller particles, reducing the volume of waste and facilitating subsequent processing and recycling. Traditional food waste crushing equipment mostly uses single-roller crushing or co-directional double-roller crushing structures, which have problems such as low crushing efficiency, poor handling capacity for hard materials, and easy entanglement and blockage. When processing food waste containing high-toughness components such as fibers and bones, conventional toothed rollers are prone to material jamming due to synchronous biting, requiring frequent shutdowns for cleaning and reducing operating efficiency.

[0003] To address the aforementioned issues, a double-roller toothed staggered kitchen waste crusher has been developed. Utility Model Content

[0004] In order to overcome the problems of low crushing efficiency, poor handling capacity of hard materials, and easy entanglement and blockage of traditional kitchen waste crushing equipment, conventional toothed rollers are prone to material jamming due to synchronous biting when processing kitchen waste containing high toughness components such as fibers and bones, requiring frequent shutdowns for cleaning and reducing operating efficiency. This utility model provides a double-roller toothed staggered kitchen waste crushing box.

A side plate is connected to the upper left side of the installation box by fasteners. A drive assembly is provided inside the installation box. The drive assembly includes a dual-shaft motor and bevel gears. The dual-shaft motor is installed on the left side of the installation box.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] A double-roller toothed staggered type kitchen waste crusher, such as Figures 1-3 As shown, the device includes a mounting box 1, a hopper 2 connected to the upper part of the mounting box 1, a first double-toothed roller 3 rotatably connected to the front of the mounting box 1, and a second double-toothed roller 4 rotatably connected to the rear of the mounting box 1. The teeth on the second double-toothed roller 4 and the first double-toothed roller 3 are staggered. A side plate 5 is connected to the upper left side of the mounting box 1 by fasteners. The side plate 5 has a detachable connection structure. A drive assembly 6 is provided inside the mounting box 1. The drive assembly 6 includes a dual-shaft motor and bevel gears. The dual-shaft motor is installed on the left side of the mounting box 1. Bevel gears are connected to the output shafts of the dual-shaft motor. Bevel gears are also connected to the left sides of the first double-toothed roller 3 and the second double-toothed roller 4. Two adjacent bevel gears mesh with each other. A collection bucket 7 is placed inside the mounting box 1. A side door 8 is rotatably connected to the right side of the mounting box 1. A locking device that locks the side door 8 is rotatably connected to the mounting box 1. A cleaning mechanism 9 is provided on the mounting box 1.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cleaning mechanism 9 includes a mounting base 91. The upper part of the mounting box 1 is connected to a symmetrical mounting base 91. Five sets of first cleaning components 92 are slidably connected to the mounting base 91. Two dampers 95 are connected between each set of first cleaning components 92 and the mounting base 91. Springs 94 are connected inside each damper 95. Several second cleaning components 93 are connected to each set of first cleaning components 92. The second cleaning components 93 are arranged at a staggered cleaning angle with the adjacent first cleaning components 92.

[0023] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a sealing mechanism 10, which includes a sealing plate 101. The sealing plate 101 is rotatably connected to the upper rear part of the hopper 2. A handle 102 is connected to the upper side of the sealing plate 101, and a sealing ring 103 is connected to the inner side of the sealing plate 101.

[0024] It should be noted that the food waste crushing bin is a device used to process food waste generated in households or commercial establishments. It mechanically crushes food waste into smaller particles, reducing its volume and facilitating subsequent processing and recycling. When using this device, the operator uses the handle 102 to flip the sealing plate 101 upwards, then pours the food waste into the hopper 2, and flips the sealing plate 101 back to its original position. The sealing plate 101 provides a seal, preventing odor leakage and material splashing during the crushing process. The sealing ring 103 enhances the airtightness of the hopper 2. Then, the dual-shaft motor is started. The output shaft of the dual-shaft motor drives the first double-toothed roller 3 and the second double-toothed roller 4 to rotate in opposite directions via two sets of bevel gears. The teeth on the first double-toothed roller 3 and the second double-toothed roller 4 are staggered. When the peak of the front roller tooth aligns with the valley of the rear roller tooth trough, a dynamic... In the shearing space, when waste falls into the gap between the two rollers under gravity, the counter-rotating toothed blocks generate a powerful shearing and tearing combined effect, which can significantly improve the crushing effect and thus improve the crushing efficiency. During the crushing process, the cleaning mechanism 9 on the inner wall of the installation box 1 works synchronously. The five sets of first cleaning parts 92, under the elastic support of the damper 95 and the spring 94, reciprocate against the adjacent first double toothed roller 3 and second double toothed roller 4. At the same time, the second cleaning parts 93 and the first cleaning parts 92 are arranged at staggered angles to form a three-dimensional cleaning network, thereby ensuring the cleaning effect and effectively reducing the residue rate on the first double toothed roller 3 and the second double toothed roller 4. The crushed material falls into the collection bucket 7 through the bottom of the installation box 1. When the collection bucket 7 collects the material to the threshold, the locking part is rotated and the side door 8 is opened outward to pull the collection bucket 7 outward, thereby quickly replacing the collection bucket 7.

[0025] 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 to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
