[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See Figure 1-4This embodiment provides a kitchen waste crushing device, including a crushing cylinder 2, in which a crushing rotary blade 3 and a fixed blade 4 are provided. The crushing rotary blade 3 rotates in the crushing cylinder 2, and the fixed blade 4 is fixed. The crushing rotary blade 3 and the fixed blade 4 cooperate to crush the waste into particles.

[0032] The fixed blades 4 are located at the bottom and rear wall of the crushing drum 2, enabling multi-directional crushing. Due to gravity, food waste tends to accumulate at the bottom of the horizontally positioned crushing drum 2. Therefore, the fixed blades 4 are located at the bottom of the crushing drum 2 to improve crushing efficiency. The rotating crushing blades 3 are located at the rear of the crushing drum 2, and the fixed blades 4 are located on the rear wall of the crushing drum 2 to further enhance crushing efficiency.

[0033] The above-mentioned pulverizing blade 3 includes a rotating shaft 31 and a rotating blade 32 connected to the rotating shaft 31. The rotating blade 32 rotates with the rotating shaft 31 to pulverize the kitchen waste. A paddle assembly 5 is connected to the rotating shaft 31. The paddle assembly 5 is located in front of the rotating blade 32. The paddle assembly 5 does not participate in the crushing operation. The paddle assembly 5 is used to stir the kitchen waste in front of the pulverizing drum 2, causing it to move inward, that is, toward the pulverizing blade 3. The paddle assembly 5 includes a connecting rod 51 and an extension rod 52. The connecting rod 51 is radially arranged on the rotating shaft 31, that is, the connecting rod 51 extends in a direction perpendicular to the rotating shaft 31. One end of the extension rod 52 is connected to the outer end of the connecting rod 51, and the other end thereof extends forward. The extension rod 52 is arranged parallel to the rotating shaft 31. The extension rod 52 is provided with a rubbing piece 53 on the side of the pulverizing drum 2. The rubbing piece 53 is arranged to fit the inner wall surface of the pulverizing drum 2 to maintain the cleanliness of the inner wall of the pulverizing drum 2.

[0034] The above-mentioned kitchen waste crushing device also includes a processing chamber 1, and the crushing drum 2 is installed at an angle in the processing chamber 1. The input end 21 of the crushing drum is higher than the output end 22 of the crushing drum, that is, it is set downwardly at an angle, and gravity is used to better transport the material from the front feeding end to the rear discharge end. Since the rotating blade 32 is located in the middle and rear part of the crushing drum 2, this design also allows the kitchen waste to be fully crushed.

[0035] During operation, kitchen waste is put into the front end opening of the crushing drum 2, and the rotating shaft 31 drives the rotating blade 32 and the paddle assembly 5 to rotate. The paddle assembly 5 stirs the kitchen waste in the inclined crushing drum 2 and moves the kitchen waste toward the rotating blade 32, avoiding the accumulation of kitchen waste at the front end of the crushing drum 2, thereby affecting the crushing efficiency. The rotating blade 32 and the fixed knife 4 crush the kitchen waste into particles. At the same time, the wiping piece 53 scrapes off the kitchen waste adhered to the crushing drum 2 during the rotation process, and the kitchen waste moves backward to the discharge end of the crushing drum 2.

[0036] The outer wall surface of the above-mentioned crushing tube 2 is wrapped with a heat-insulating cover 6. In actual work, the entire crushing tube 2 needs to be heated to soften the waste material to help effectively crushing. The heat-insulating cover 6 can prevent heat loss and keep the temperature stable.

[0037] The rear end of the extension rod 52 is removably provided with a magnetic element 54, which is typically circular in structure. A Hall effect sensor 7 is provided on the outer wall of the crushing drum 2. Furthermore, the Hall effect sensor 7 is positioned outside the heat-insulating cover 6 to prevent damage to the Hall effect sensor 7 from high temperatures. The magnetic element 54 and the Hall effect sensor 7 sense each other, thereby acquiring information about the current position of the rotating blades 32 and the paddle assembly 5.

[0038] Two rotating blades 32 and two sets of paddle assemblies 5 are mounted opposite each other on the rotating shaft 31. The rotating blades 32 and paddle assemblies 5 are arranged at staggered angles. Each paddle assembly 5 includes a connecting rod 51 and an extension rod 52. A wipe 53 is provided on one of the extension rods 52, and a magnetic member 54 is provided on the other extension rod 52. Typically, only one wipe 53 is sufficient, which simplifies the structure and saves costs. Furthermore, wipes 53 can be provided on both extension rods 52 to improve cleaning performance.

[0039] The outer end of the connecting rod 51 is provided with a clamping member 511 having a U-shaped cross-section. A fixing seat 512 is integrally formed within the clamping member 511. The end of the extension rod 52 is provided with a fixing member 521 that mates with the fixing seat 512 and is mounted on the fixing seat 512. The fixing member 521 includes a screw hole 522, the outer end of which is covered with a shielding cap 523. The shielding cap 523 shields the screw hole 522, thereby preventing waste from entering the screw hole 522.

[0040] The extension rod 52 has an axial slot 524 on the side facing the crushing drum 2. The cleaning sheet 53 includes a connecting side 531 and a cleaning side 532. The connecting side 531 is inserted into the slot 524, while the cleaning side 532 is aligned with the inner wall of the crushing drum 2. The cleaning side 532 has a triangular cross-section, with one of its tips aligned with the crushing drum 2 to improve cleaning efficiency.

[0041] The extension rod 52 and the wiper 53 are both detachably connected. When the extension rod 52 or the wiper 53 is damaged, there is no need to replace the entire paddle rod, only the corresponding damaged parts need to be replaced, which improves maintenance efficiency and saves costs.
