Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a filtering and conveying device. Background Art

[0002] After a pet cat excretes feces in a cat toilet, the cat litter needs to be processed and the cat litter surrounding the feces needs to be removed from the cat litter box to ensure the cleanliness of the cat litter box. Generally, people scoop up the feces surrounded by cat litter with a shovel and remove them one by one. When shoveling feces with a shovel, the feces may be broken or crushed by the shovel in the process of searching for feces buried in the cat litter. Therefore, fecal fragments and cat litter that absorbs feces will remain in the litter box until the cat litter is replaced, which will continue to be unsanitary and may cause health problems for pet cats. At the same time, the manual shoveling method is inefficient, time-consuming and labor-intensive.

[0003] In order to improve the cleaning efficiency of pet feces, a filtering structure for cat litter has emerged. For example, the document with application number JP2006111344 discloses a cat toilet feces cleaning net, which is formed by fitting a filter net on the inner surface of the cat toilet body and then filling it with cat litter. When cleaning, the filter net can be lifted to filter the cat litter, and the clean cat litter can fall from the filter net into the cat toilet body, and the feces and cat litter on it will be wrapped and taken away by the filter net. Compared with the manual shoveling method, the filter net method shortens the cleaning time to a certain extent, but it requires frequent replacement of the filter net, and when there is a lot of cat litter, it is difficult to achieve a sufficient filtering effect, which will also cause waste of cat litter.

[0004] The document with application number CN201821989553.4 discloses a fully automatic intelligent cat toilet, and specifically discloses: the separation mechanism body includes an external gear ring, a silicone bowl and a separation mechanism storage bin, the rotation axis of the separation mechanism storage bin is tilted relative to the horizontal plane, and preferably, the angle between the rotation axis and the horizontal plane is 20°. The separation mechanism storage bin is provided with an entrance and a fecal outlet. Of course, the upper shell is provided with a concession for the entrance, and a grille step is installed at the entrance, which can filter out some cat litter remaining on the cat's paws. When in use, the cat's excrement can enter the separation mechanism storage bin from the entrance, and after a series of treatments, it is output from the feces outlet to the feces collection system. The separation mechanism storage bin is installed with a silicone bowl, a hexagonal honeycomb filter and a sand box. The hexagonal honeycomb filter is installed in the separation mechanism storage bin through a one-way movable door. The silicone bowl contains cat litter. The separation mechanism storage bin rotates counterclockwise, and the weight is adjusted. Under the action of force, the cat's excrement first clumps with the cat litter, and then the cat litter that is not clumped with the excrement will pass through the hexagonal honeycomb filter and fall into the sand box behind the hexagonal honeycomb filter. The excrement clumped with the cat litter is blocked by the hexagonal honeycomb filter. When the separation mechanism storage bin continues to rotate counterclockwise, the excrement clumped with the cat litter passes through the outer surface of the sand box and falls to the feces outlet, and then falls into the feces collection system from the feces outlet. After that, the separation mechanism storage bin begins to rotate clockwise, and the cat litter that falls into the sand box pushes the hexagonal honeycomb filter open under the action of gravity. The cat litter flows out of the gap of the hexagonal honeycomb filter and returns to the silicone bowl. The cat toilet in the above document can realize automatic filtering and separation of cat litter, but the area of ​​the filter is small. When there is a lot of cat litter, some cat litter will inevitably be discharged directly through the feces outlet without being filtered by the filter, resulting in insufficient filtration of cat litter.
