A fixing component is provided at the connection between the screen layer and the main body, and a connecting component is provided at the connection between the discharge layer and the main body. Pins are provided on both the connecting component and the fixing component. The cat litter raw materials are only mixed once by staggered mixing blades. The stratification of different substances in the raw materials is not fully broken down, resulting in uneven mixing of the deodorant. Summary of the Invention

[0004] To address the problems of clumping caused by prolonged stirring and uneven mixing due to insufficient stirring time in existing cat litter mixing devices, this invention proposes a cat litter mixing device.

[0005] A mixing device for making cat litter includes a box body, which is a hollow cavity, and a feed inlet is provided on the top of the box body;

[0008] The first stirring shaft is embedded in the mixing and crushing chamber, and its two ends are rotatably connected to the inner wall of the chamber; the first stirring shaft is equipped with a first motor.

[0009] The stirring blades consist of multiple blades fitted onto the outer surface of the first stirring shaft; they generate horizontal shearing force to break up agglomerates on the surface of the raw materials, thus initiating the mixing process. Simultaneously, the stirring blades are spirally arranged to horizontally propel the materials.

[0010] Vertical stirring rods, multiple vertical stirring rods are vertically connected to the outer surface of the first stirring shaft, and the vertical stirring rods are installed alternately with the stirring blades; the vertical stirring rods are inserted into the material to forcibly agitate the material at different levels, and at the same time, crushing heads are installed to locally impact the clumps;

[0011] A spring stirring rod is fitted onto the outer surface of either end of the first stirring shaft; the spring stirring rod swings freely at its end, agitating the four corners and bottom of the container to clean up residual material and prevent material accumulation.

[0012] The discharge chamber is located at the bottom of the box body.

[0013] The discharge port is located at the bottom of the box and below the discharge chamber.

[0014] Furthermore, it also includes an agglomeration crushing chamber and a screening chamber, sandwiched between the mixing and crushing chamber and the discharge chamber. The screening chamber separates the qualified particles from the uncrushed lumps after mixing, preventing blockage of subsequent processing. The agglomeration crushing chamber performs high-intensity crushing on the screened lumps to ensure particle uniformity. A screen is installed below; qualified cat litter enters the storage chamber, while excessively large particles enter the waste bin.

[0015] Furthermore, an installation frame is installed between the agglomeration crushing chamber and the screening chamber. The installation frame is connected to the inner wall of the box. A sieve plate is embedded in the screening chamber and is placed at an angle.

[0016] Furthermore, the opening below the agglomeration crushing chamber is connected to the discharge chamber, and the screening chamber is connected to the discharge chamber through the screening material outlet.

[0017] Furthermore, the sieve plate is equipped with a vibration motor; driving the sieve plate to vibrate at high frequency and micro amplitude to prevent cat litter particles from clogging the sieve holes.

[0018] Furthermore, the end of the sieve plate is connected to a first buffer spring, the first buffer spring is connected to a connecting block, and a limiting sleeve is also included. The limiting sleeve is fixedly installed on the surface of the mounting frame near the screening chamber and on the inner wall of the box. The connecting block moves linearly along the inner surface of the limiting sleeve. A limiting ring is provided at the opening of the limiting sleeve. A second buffer spring is connected between the connecting block and the bottom of the limiting sleeve.

[0019] Furthermore, buffer springs are installed to reduce vibration transmission to the housing and extend the equipment's lifespan.

[0020] Furthermore, a limit block is provided at the end of the sieve plate, and a limit groove is provided on the inner wall of the box and at the connection between the mounting frame and the sieve plate, and the limit block moves linearly along the limit groove.

[0021] Furthermore, the limiting block and limiting groove ensure that the screen plate vibrates linearly, reducing screen hole blockage caused by lateral offset, while constraining the screen plate to move only in a straight line, avoiding uneven screening caused by tilting vibration.

[0022] Furthermore, it also includes two third stirring shafts, which are embedded in the agglomeration crushing chamber. The ends of the third stirring shafts are rotatably connected to the mounting frame. Multiple crushing blades are installed on the surface of the third stirring shafts, and the third stirring shafts are equipped with a third motor.

[0023] Furthermore, a screen is installed below the crushing blades, and the screen is arranged at an angle. A waste bin is set along the inclined direction of the screen. The blades are arranged in a staggered manner to improve the crushing efficiency, and the inclined angle of the screen helps large particles move into the waste bin.

[0024] Furthermore, it also includes a second stirring shaft, which is embedded in the discharge chamber, and both ends of the second stirring shaft are rotatably connected to the inner wall of the box; the surface of the second stirring shaft is connected with feeding blades.

[0025] Furthermore, the spacing between adjacent feeding blades gradually increases along the direction from the third motor to the discharge port, and the spiral propulsion discharge prevents material accumulation and blockage. At the same time, the blade spacing increases along the direction from the third motor 9 to the discharge port 12, with the front blade spacing and the rear blade spacing. The front blade compacts the cat litter to prevent leakage, and the rear blade accelerates the discharge, improving the discharge efficiency.

[0026] Furthermore, a crushing head is installed at the end of the vertical stirring rod.

[0027] Furthermore, a controller is installed on the outer surface of the box. The controller is electrically connected to the motor and controls the motor speed according to the material discharge situation, thereby controlling production.

[0028] When the device is working, it includes the following steps: feeding and preliminary mixing: raw materials, including cat litter substrate and deodorant, enter the mixing and crushing chamber through the feed inlet. The motor drives the first stirring shaft to drive the stirring blades, vertical stirring rod and spring stirring rod to work together; the stirring blades move horizontally in a spiral motion, promoting the material circulation and mixing, breaking up horizontal stratification;

[0029] The vertical stirring rod tumbles the material up and down, eliminating vertical stratification, while the end crushing head breaks up initial clumps. The spring stirring rod flexibly disturbs the edges and bottom corners of the container, reducing residue.

[0030] Screening and agglomeration separation: The mixed material enters the screening chamber, and the inclined screen plate vibrates at high frequency under the drive of the vibrating motor: qualified particles fall into the discharge chamber through the screen holes; unbroken agglomerates slide into the agglomeration crushing chamber along the screen plate; two-stage springs absorb vibration energy and reduce equipment wear.

[0031] Secondary crushing and recycling of clumps: The third stirring shaft drives high-speed crushing blades to perform high-intensity shearing on the clumps: After crushing, the particles are filtered twice through an inclined screen. Qualified particles are returned to the mixing and crushing chamber for remixing, while substandard waste slides into the waste bin along the screen.

[0032] Discharge: Qualified particles enter the discharge chamber, and the second stirring shaft drives the variable pitch feeding blades. The small gap at the front end compacts the material to prevent leakage, while the large gap at the rear end accelerates the discharge, improves fluidity and discharge efficiency, and prevents material accumulation from causing blockage and clumping.

[0033] The inverted cone-shaped discharge port reduces lateral pressure, and the surface of the discharge port is coated with a wear-resistant coating to prevent clogging.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The vertical stirring rod, through its end-mounted crushing head, forcibly agitates the material layer, breaking up vertical stratification and impacting initial agglomerates; the spring-loaded stirring rod swings freely at the end of the stirring shaft, cleaning the edges and bottom corners of the tank to prevent material residue from clumping; the spiral design of the stirring blades generates horizontal shearing force, promoting material circulation and mixing, and eliminating horizontal stratification. The combination of these structures significantly improves mixing uniformity and reduces agglomeration during the mixing process.

[0036] 2. The high-frequency micro-amplitude vibration of the sieve plate is constrained by the limiting blocks and limiting grooves to prevent sieve hole blockage and improve screening efficiency; the first and second buffer springs absorb vibration energy, reduce the impact on the housing, and extend the equipment life. Qualified particles fall directly into the discharge chamber, while substandard particles clump together and slide into the agglomeration crushing chamber, effectively separating materials and avoiding blockage in subsequent processes.

[0037] 3. The third stirring shaft drives the high-speed crushing blades to perform secondary shearing on the non-compliant clumps. The inclined screen, together with the waste bin, recovers large particles to ensure the uniformity of the final particles. The spacing of the feeding blades gradually increases along the direction from the third motor to the discharge port. The front end compacts the material to prevent leakage, and the rear end accelerates the discharge. Combined with the inverted cone discharge port, it reduces lateral pressure, significantly improves discharge efficiency, and prevents blockage. Attached Figure Description
