The length, width and height of the cat litter box are 640mm, 370mm and 360mm respectively.
The utility model discloses a theory of operation and work flow are:
before the operation of the litter box, the litter needs to be added to the litter containing slot 44 and the space between the litter pre-separating plate 210 and the litter containing slot 44, and the height of the added litter cannot exceed the height of the litter leakage preventing plate 43. In the initial position, the cat litter preseparation plate 210 and the upper screen 45 are both horizontal, and the cat litter temporary storage hopper 32 is located on the ground or on the placing table and is located in the action area of the cat litter preseparation outlet at the front end of the cat litter preseparation plate 210.
Cat excretes back cat litter box and gets into the duty cycle, the following workflow that is cat litter box:
1) pre-separating cat litter: cat litter preseparation board driving motor 26 starts, drives a lead screw 27 and rotates, drives a branch rod 23 through a lead screw ring flange 214 and moves down along a lead screw 27, makes cat litter preseparation board 210 use spacing post 22 to rotate anticlockwise as the center of rotation, and the front end of cat litter preseparation board 210 descends, and cat litter preseparation board 210 becomes to incline forward the position by horizontal position, and most cat litter is emptyd into cat litter temporary storage bucket 32. The litter preseparation plate drive motor 26 then reverses direction and the litter preseparation plate 210 returns to the horizontal position.
2) Separating cat litter from caking excrement: the upper-layer screen driving motor 46 rotates forward and backward to drive the upper-layer screen driving rocker 411 to swing back and forth, so that the upper-layer screen 45 vibrates; firstly, the upper layer screen 45 rotates clockwise by about 30 degrees under the driving of the upper layer screen driving rocker 411, so that the upper layer screen 45 forms a certain inclination angle with the horizontal plane, at the moment, the rear end of the upper layer screen 45 and the rear end of the hollow-out area of the cat litter containing groove 44 form an opening, and caked excrement bonded with the cat litter can fall into the excrement collecting groove 1 from the opening; then the upper layer screen driving rocker 411 periodically makes clockwise/anticlockwise reciprocating rotation with the rotation angle of 15 degrees on the basis of 30 degrees, namely, the periodic reciprocating rotation is realized within the range of 30-45 degrees, so that the upper layer screen 45 vibrates; in the vibration process, the cat litter above the upper screen 45 falls into the cat litter pre-separation plate 210 through the strip-shaped openings 452, the caked excrement falls into the excrement collecting tank 1 below along the inclined plane formed by the upper screen 45 under the vibration effect, so that the separation of the cat litter and the caked excrement is completed, and the upper screen 45 returns to the initial horizontal position under the effect of the upper screen driving motor 46 after the separation is completed. In the process of separating cat litter from caked excrement, the second lead screw driving motor 49 does not work, so that the scissor type push rod group 410 is in a contraction state, and the scissor type push rod group 410 and the litter pushing plate 413 do not interfere with the vibration of the upper screen 45.
3) And (3) backfilling cat litter: the cat litter temporary storage hopper driving motor 34 drives the driving bevel gear 38 to rotate, the driving bevel gear 38 drives the driving shaft 36 to rotate through the driven bevel gear 37, the driving rocker arm 35 and the driven rocker arm 31 are enabled to rotate, the cat litter temporary storage hopper 32 is lifted upwards to be right above the cat litter box, at the moment, the cat litter temporary storage hopper driving motor 34 stops rotating and keeps the position unchanged, and the position of the cat litter temporary storage hopper 32 above the cat litter box is kept unchanged; at this time, the litter baffle driving motor 310 drives the litter baffle 39 to rotate, so that the litter pouring opening 321 is opened, and the litter falls into the litter containing groove 44 from the litter pouring opening 321; when the cat litter completely falls into the cat litter containing groove 44, the cat litter baffle driving motor 310 drives the cat litter baffle 39 to rotate reversely, and the cat litter pouring opening 321 is closed; then the temporary litter storage hopper drive motor 34 rotates reversely, adjusts the temporary litter storage hopper 32 to the original position, and waits for the collection of the litter again.
4) Flattening cat litter: the second lead screw driving motor 49 is started to drive the second lead screw 48 to rotate, so that the second lead screw flange 417 slides towards the rear end of the cat litter box along the second lead screw 48 to drive the scissor type push rod group 410 to extend, further drive the litter pushing plate 413 to move towards the rear end of the cat litter box to push the cat litter flat; when the sand pushing plate 413 moves to the end, the second lead screw driving motor 49 rotates reversely, the scissor type push rod group 410 contracts, and the sand pushing plate 413 returns to the original position.
Through the steps, the separation, collection and backfilling work of the cat litter and the caked excrement is completed, and the whole cat litter box can wait for collecting the excrement again.
In the present specification, the face of the litter pre-separating outlet of the litter pre-separating plate 210 is taken as the front, and both clockwise and counterclockwise directions are viewed from the right side direction of the litter box.
The utility model discloses the nothing is mentioned the part and is applicable to prior art.
