Description

Technical Field

[0001] The utility model relates to the field of crushing mechanisms, in particular to a crushing mechanism of a kitchen waste crushing and separation machine. Background Art

[0002] Kitchen waste refers to the garbage generated in residents' daily lives and food processing, catering services, unit catering and other activities, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, egg shells, tea dregs, bones, etc. Its main sources are home kitchens, restaurants, canteens, markets and other industries related to food processing. When processing kitchen waste, a crushing separator is needed to crush and separate the solid and liquid from the kitchen waste.

[0003] At present, a Chinese utility model with the announcement number CN219466716U discloses a crushing mechanism of a crushing separator, including a shell, a crushing device and a driving motor driving the crushing device to crush materials, the shell is provided with a feed port and a discharge portion, the discharge portion includes a first discharge area and a second discharge area, the first discharge area is provided with a plurality of blocking blocks at intervals, the blocking blocks divide the first discharge area into a plurality of discharge ports, the crushing device includes a crushing roller and a plurality of partition baffles fixedly connected to the shell at intervals, the driving motor drives the crushing roller to rotate and cooperate with the partition baffle to squeeze and crush the materials, and at the same time squeezes out the materials that cannot be crushed from the second discharge area. By adopting the above technical solution, the utility model provides a crushing mechanism that can squeeze out the materials that cannot be crushed from the second discharge area.

[0004] To sum up, although the crushing mechanism of the crushing separator can achieve the function of crushing kitchen waste, there are still certain problems in its use. For example, the crushing mechanism of the crushing separator can only crush once, and the kitchen waste is prone to uneven crushing after crushing. For example, food packaging bags in the kitchen waste are prone to incomplete crushing, resulting in poor crushing effect. Utility Model Content

[0005] The utility model aims to provide a crushing mechanism of a kitchen waste crushing and separation machine, which has the advantages of good crushing effect and anti-adhesion.

[0015] The above technical solution is adopted to facilitate the stepping motor to drive the rotating rod to rotate.

[0016] The utility model is further configured as follows: a discharge cavity is connected to the surface of the discharge pipe of the cylinder, and a filter screen is installed inside the discharge pipe of the cylinder.

[0017] The above technical solution is adopted to facilitate the separation and discharge of solid and liquid waste in kitchen waste.

[0018] The utility model is further configured as follows: legs are bolted to the bottom of the cavity, and the number of the legs is four.

[0019] The above technical solution is adopted to support the cavity.

[0020] The utility model is further configured as follows: the top of the cavity is connected with a feed hopper.

[0021] The above technical solution is adopted to facilitate the feeding of the cavity.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. The utility model installs a crushing roller inside the cavity. When the driving motor is started, the kitchen waste can be crushed for the first time. When the stepping motor is started, the rotating rod can be driven to rotate under the action of the bevel gear. Under the action of the transmission wheel and the belt, the three rotating rods rotate at the same time and drive the crushing teeth to crush the kitchen waste for the second time, thereby ensuring the uniform crushing of the kitchen waste and preventing the occurrence of incomplete crushing, and achieving a better crushing effect.

[0024] 2. The utility model has a cleaning seat installed inside the cylinder, and a cleaning groove installed on the cleaning seat. When the rotating rod rotates, the crushing teeth are driven to rotate, so that the crushing teeth slide through the cleaning groove.
