Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying, in particular to a separation mechanism. BACKGROUND

[0002] After the pet cat excretes feces in the cat toilet, the cat litter needs to be treated, and the cat litter surrounding the feces is cleaned from the cat litter basin to ensure the cleanliness of the cat litter basin. Generally, the feces surrounded by the cat litter is scooped up one by one by a person using a shovel, and the feces is scooped up. When the feces is scooped up with the shovel, the feces may be broken or crushed in the process of searching for the feces buried in the cat litter, so the feces fragments and the cat litter absorbing the feces will remain in the sand toilet until the cat litter is replaced, which will continue to be unhygienic and may affect the health of the pet cat. At the same time, the manual scooping method is low in efficiency and time-consuming and laborious.

[0003] In order to solve the technical problems of low efficiency and time-consuming and laborious of manual scooping, a device capable of automatically treating cat litter appears in the prior art. For example, a file with application number CN202020348579.1 discloses a screening assembly for cat toilet and a cat toilet, which screens cat litter containing excrement to provide a good and clean defecation place for pet cats. The screening assembly for cat toilet includes a rotating container, a sand blocking piece and a screening piece. The cat litter is laid in the rotating container, and after the pet cat excretes in the cat litter on the cat litter, the sand blocking piece is used to block the cat litter in the rotating container, and the screening piece is used to screen the excrement in the cat litter. In this embodiment, the rotating container can be barrel-shaped and can be formed by splicing two half-barrels, the sand blocking piece can be plate-shaped, and the screening piece can be arc-shaped plate-shaped. The specific working principle is as follows: first, the rotating container is in the initial position, the cat litter containing cat excrement is laid on the bottom of the rotating container, and the rotating container is rotated by the driving assembly from the initial position along the first direction (counterclockwise direction); then during the rotation of the rotating container along the first direction, the screening piece gradually contacts and screens the cat litter containing cat excrement, the excrement (with a small amount of cat litter) is too large to pass through the special-shaped screen hole of the screening piece, and the cat litter is small enough to pass through the special-shaped screen hole of the screening piece and enter the containing cavity, and is blocked by the sand blocking piece to prevent the cat litter from flowing out of the waste discharge port, and the excrement is discharged through the discharge port under the action of gravity; finally, the rotating container is rotated in the direction opposite to the first direction (clockwise direction), the cat litter pushes away the screening piece, the screening piece rotates counterclockwise around its pivot by a certain angle, and the cat litter is conveniently and quickly restored to the preset position.

[0004] The screening assembly in the above-mentioned file can be used for automatic screening of cat litter, but the rotating container can only rotate one level. In the case of excessive cat litter, the cat litter cannot be fully tumbled and screened, which leads to the problem that the cat litter beyond the width range of the screening piece cannot be filtered and screened, resulting in poor cleaning effect. Summary of the Invention

[0005] To address the technical problem that existing screening components only rotate in a single stage and cannot perform multi-angle tumbling and screening of cat litter, resulting in insufficient screening and poor cleaning effect, this invention provides a separation mechanism that solves the above-mentioned technical problem.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention provides a separation mechanism, comprising:

[0008] The cabin has an entrance and an exit;

[0009] A spherical crown filter is built into the chamber. The crown of the spherical crown filter has a discharge channel formed on its top. The discharge channel is surrounded by a closed isolation curved surface and is connected to the outlet. A receiving space is formed between the spherical crown filter and the chamber.

[0010] A spherical capsule, wherein the capsule body is rotatably assembled in a secondary manner via the spherical capsule, the spherical capsule being rotatably assembled, and the capsule body extending at least partially into and rotatably assembled to the spherical capsule.

[0011] According to one embodiment of the present invention, the spherical crown capsule drives the capsule body to rotate along a first axis, and the capsule body rotates relative to the spherical crown capsule along a second axis, the second axis being perpendicular to the first axis.

[0012] According to one embodiment of the present invention, the spherical cap is hemispherical, the spherical cap is rotatably mounted on the carrier, and there is a gap between the portion of the cabin located inside the spherical cap and the spherical cap.

[0013] According to one embodiment of the present invention, the cabin includes a first cabin located outside the spherical cabin and a second cabin located inside the spherical cabin. Both the first cabin and the second cabin are hemispherical. The outer diameter of the first cabin is larger than the outer diameter of the second cabin. The first cabin and the second cabin are connected by a transition surface.

[0014] According to one embodiment of the present invention, the outer diameter of the first cabin is the same as the outer diameter of the spherical crown cabin.

[0015] According to one embodiment of the present invention, teeth are formed on the transition surface.

[0016] According to one embodiment of the present invention, the carrier rotatably supports the spherical crown chamber via two shafts, one shaft being rotatably connected to the spherical crown chamber; the other shaft being rotatably engaged with the spherical crown chamber and meshing with the teeth on the transition surface via gears.

[0017] According to one embodiment of the present application, two of the shafts are driven by driving devices, which are covered by the carrier body.

[0018] According to one embodiment of the present application, an opening is formed at the crown of the spherical crown cabin, which is communicated with the outlet, and the inlet is offset relative to the outlet.

[0019] According to one embodiment of the present application, a valve plate is arranged at the opening, which closes the opening when it is located outside the carrier body, and is opened by an unlocking member in the carrier body when it is rotated into the carrier body.

[0020] Compared with the prior art, the present application has the following advantages:

[0021] The separation mechanism of the present application realizes two-stage rotary assembly of the cabin body through the spherical cabin, i.e. the spherical cabin drives the cabin body to rotate, and the cabin body rotates relative to the spherical cabin. In the case of two-stage rotation of the cabin body, the cat litter in the cabin body performs a tumbling motion, thereby ensuring that all cat litter can pass through the filtering action of the spherical filter screen, realizing sufficient screening of the cat litter, and achieving good cleaning effect. In addition, the spherical filter screen is arranged in the cabin body, increasing the filtering surface. The crown of the spherical filter screen forms a discharge passage, so that the cat litter needs to pass through the filter screen part of the spherical filter screen to reach the discharge passage, thereby ensuring that all cat litter is necessarily subjected to sufficient filtering. In addition, the closed isolation curved surface forming the discharge passage can be surrounded by the cabin body to form a containing space for containing cat litter filtered by the filter screen part of the spherical filter screen.

[0022] The separation mechanism of the present application rotates the cabin body along a first axis by the spherical cabin, rotates the cabin body along a second axis relative to the spherical cabin, and the second axis is perpendicular to the first axis, so that the cabin body can rotate in two perpendicular directions, and the cat litter in the cabin body can perform a tumbling motion, ensuring sufficient filtering of the cat litter.

[0023] The separation mechanism of the present application is provided with a spherical cabin body with a variable outer diameter, so that the second cabin body of the cabin body can be rotatably assembled in the spherical cabin, and the first cabin body of the cabin body has the same outer diameter as the spherical cabin, so that the overall structure formed by the cabin body and the spherical cabin is spherical, which is aesthetically pleasing and does not occupy much space during operation. The second cabin body is arranged in the spherical cabin and has a gap with the spherical cabin, facilitating assembly of the driving structure for driving the cabin body to rotate relative to the spherical cabin.

[0024] The transition surface between the separation mechanism, the first cabin body and the second cabin body is formed with teeth, so that the driving structure drives the cabin body to rotate relative to the spherical cap cabin in a gear transmission mode; specifically, one driving device drives the spherical cap cabin and the cabin body thereon to rotate by driving the shaft connected with the spherical cap cabin to rotate; another driving device drives the shaft connected with the spherical cap cabin to rotate, so that the gear on the shaft meshes with the teeth on the transition surface to drive the cabin body to rotate relative to the spherical cap cabin, thereby meeting the secondary rotation of the cabin body, and the whole process is automated and high in working efficiency.
