Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cat litter mixing devices, specifically relating to a multi-mineral composite cat litter raw material mixing device. Background Technology
[0002] Cat litter is a granular substance used by cats to defecate and urinate. It can dry pet feces and reduce indoor odors. Multi-mineral composite cat litter refers to two or more raw materials (different types, colors, and coarseness) mixed in a specified weight ratio to achieve good absorbency, clumping ability, and effective deodorization. The absorbency, clumping ability, and dust content of cat litter are important factors that determine its quality. Too much dust will not only affect the user experience but also the health of kittens, making them more susceptible to lung infections.
[0003] Existing cat litter mixing devices have a relatively simple structure. They generally involve directly putting multiple raw materials into a mixing tank for mixing. This mixing method not only results in poor uniformity and low mixing efficiency, but also mixes in fine particles and dust generated during the production of raw materials. As a result, the compound cat litter contains a lot of particles and dust after mixing, which reduces the production quality of the compound cat litter. Utility Model Content
[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a multi-mineral composite cat litter raw material mixing device. This device can filter out fine particles and dust that easily generate dust in the raw materials. The air blowing mechanism can blow out the filtered fine particles and dust, effectively reducing the dust content in the cat litter and improving the production quality. At the same time, the stirring and mixing mechanism can fully mix the various raw materials in the mixing tank, preventing the raw materials from separating due to different weights. This effectively improves the uniformity of the mixing of various raw materials and makes it easier to uniformly dispense them later.
[0005] A multi-mineral composite cat litter raw material mixing device includes a mixing bucket and a raw material conveying pipe. The mixing bucket is equipped with a stirring and mixing mechanism for mixing multiple raw materials. A bucket lid is fixedly connected to the top of the mixing bucket, and a raw material conveying pipe is provided on the top of the bucket lid. Both ends of the raw material conveying pipe are equipped with inner tube structures for receiving and filtering the raw materials. The inner tube structure is equipped with a conveying mechanism for conveying the raw materials. A middle transition pipe that can communicate with the inner tube structure is provided in the middle part of the raw material conveying pipe. An air blowing mechanism that can blow away fragments and dust is provided between the middle transition pipe and the raw material conveying pipe.
[0006] Preferably, both sides of the upper surface of the raw material conveying pipe are fixedly connected to a feeding hopper, and the feeding hopper is in communication with the interior of the inner pipe mechanism.
[0007] Preferably, the mixing mechanism includes a first drive motor, a driving toothed plate, a driving screw rod, a driven toothed plate, and a driven screw rod. The driving toothed plate is fixedly connected to the bottom of the driving screw rod, and the bottom end of the driving screw rod is connected to the drive shaft of the first drive motor via a spline. The driven toothed plate is fixedly connected to the bottom of the driven screw rod, and there are two driven toothed plates and two driven screw rods. The two driven screw rods are respectively vertically arranged on both sides of the driving screw rod and are both drivenly connected to the driving toothed plate via the driven toothed plate. The driving screw rod and the driven screw rod are both vertically rotatably connected to the bottom of the mixing tank.
[0008] Preferably, the inner tube structure includes an inner tube and a filter screen. The inner tube is coaxially arranged with the raw material conveying pipe and fixedly connected inside the raw material conveying pipe. The diameter of the inner tube is smaller than the diameter of the raw material conveying pipe. The filter screen is fixedly connected to the inner bottom wall of the inner tube. The feed hopper is in communication with the inside of the inner tube.
[0009] Preferably, the conveying mechanism includes a second drive motor and a spiral conveying rod. The spiral conveying rod is connected to the drive shaft of the second drive motor via a spline and is transversely inserted inside the inner tube. The second drive motor is fixedly installed at the end of the raw material conveying pipe. The rotation diameter of the spiral conveying rod is adapted to the inner diameter of the inner tube. The two conveying mechanisms inside the two inner tube structures are symmetrically arranged with the vertical centerline of the raw material conveying pipe as the axis of symmetry, and the ends of the two spiral conveying rods that are close to each other are both located inside the middle transition tube.
[0010] Preferably, the blowing mechanism includes a blowing pump, an annular pipe, and an outlet pipe. The blowing pump is fixedly installed on the outer surface of the middle transition pipe and is located inside the raw material conveying pipe. The annular pipe is connected to the outlet end of the blowing pump and sleeved on the outside of the bottom of the middle transition pipe. There are two outlet pipes, and the two outlet pipes are connected to the two ends of the upper surface of the annular pipe and respectively pass through the gap between the two inner pipes and the raw material conveying pipe.
[0011] Preferably, the bottom of both ends of the raw material conveying pipe is provided with an arc-shaped outlet, and the two arc-shaped outlets are respectively connected to the gap between the two inner pipes and the raw material conveying pipe and are respectively horizontally corresponding to the two air outlets.
[0012] The beneficial effects of the above technical solution are as follows:
[0013] This multi-mineral composite cat litter raw material mixing device, through the arrangement of raw material conveying pipes, stirring and mixing mechanisms, inner pipe structures, conveying mechanisms, and air blowing mechanisms, allows different raw materials to be placed at both ends of the raw material mixing pipe. The conveying mechanism transports the raw materials from both sides into the mixing bucket. Simultaneously, as the raw materials pass through the inner pipe structure, the inner pipe structure filters out small particles and dust that are prone to dust generation, conveying larger particles to the mixing bucket. At the same time, the air blowing mechanism blows out the filtered small particles and dust, effectively reducing the dust content in the cat litter and improving the production quality. Meanwhile, the stirring and mixing mechanism thoroughly mixes the various raw materials in the mixing bucket, preventing stratification due to differences in weight, effectively improving the uniformity of the mixture and facilitating subsequent uniform packaging.

[0020] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The embodiments are described in detail below.
[0021] This embodiment provides a multi-mineral composite cat litter raw material mixing device, as shown in the attached document. Figure 1-5As shown, the device includes a mixing tank 1 and a raw material conveying pipe 2. A fixed base is fixedly connected to the bottom of the mixing tank 1, and a support leg is fixedly connected to the lower surface of the fixed base. A discharge valve pipe 19 is fixedly connected to the bottom side of the mixing tank 1 for discharging the mixed cat litter inside the mixing tank 1. The mixing tank 1 is equipped with a stirring and mixing mechanism for mixing multiple raw materials. The stirring and mixing mechanism includes a first drive motor 6, a driving toothed plate 7, a driving screw rod 8, a driven toothed plate 9, and a driven screw rod 10. The driving toothed plate 7 is fixedly connected to the bottom of the driving screw rod 8, and the bottom end of the driving screw rod 8 is connected to the drive shaft of the first drive motor 6 through a spline. The driven toothed plate 9 is fixedly connected to the bottom of the driven screw rod 10, and there are two driven toothed plates 9 and two driven screw rods 10. The two driven screw rods 10 are respectively vertically arranged on both sides of the driving screw rod 8 and are both connected to the driving toothed plate 7 through the driven toothed plate 9. The active screw 8 and the driven screw 10 are both vertically rotatably connected to the bottom of the mixing tank 1, and the active toothed plate 7 and the driven toothed plate 9 are both rotatably connected between the fixed base and the mixing tank 1. The first drive motor 6 is fixedly installed at the center of the lower surface of the fixed base. When the first drive motor drives the active toothed plate 7 and the active screw 8 to rotate clockwise, it can drive the raw material on the active screw 8 to be conveyed upward. At the same time, the active toothed plate 7 can drive the driven toothed plates 9 and the driven screw 10 on both sides to rotate counterclockwise, so that the two driven screws 10 can drive the raw material inside them to be conveyed downward. When they rotate in coordination with the active screw 8, the active screw 8 will convey the raw material to the top and then flow to the surrounding areas, while the driven screws 10 on both sides will drive the raw material around them to move downward, so that the raw material at the bottom moves to the bottom of the active screw 8, forming a circulating stirring and mixing, which can make the various raw materials more evenly mixed.
[0022] A bucket lid 3 is fixedly connected to the top of the mixing bucket 1, and a raw material conveying pipe 2 is provided on the top of the bucket lid 3. Feed hoppers 5 are fixedly connected to both sides of the upper surface of the raw material conveying pipe 2, and the feed hoppers 5 are connected to the interior of the inner tube mechanism. Both ends of the interior of the raw material conveying pipe 2 are provided with an inner tube structure for receiving and filtering the raw material. The inner tube structure includes an inner tube 11 and a filter screen 12. The inner tube 11 is coaxially arranged with the raw material conveying pipe 2 and fixedly connected inside the raw material conveying pipe 2. The diameter of the inner tube 11 is smaller than the diameter of the raw material conveying pipe 2. The filter screen 12 is fixedly connected to the inner bottom wall of the inner tube 11 and can filter the raw material entering the inner tube 11, so that small particles and dust fall between the inner tube 11 and the raw material conveying pipe 2 through the filter screen 12. The feed hopper 5 is connected to the interior of the inner tube 11 and can inject the raw material into the inner tube 11 through the feed hopper 5.
[0023] The inner tube structure is equipped with a conveying mechanism for transporting raw materials. The conveying mechanism includes a second drive motor 13 and a spiral conveying rod 14. The spiral conveying rod 14 is connected to the drive shaft of the second drive motor 13 by a spline and passes laterally inside the inner tube 11. The second drive motor 13 is fixedly installed at the end of the raw material conveying pipe 2. The rotation diameter of the spiral conveying rod 14 is adapted to the inner diameter of the inner tube 11. The two conveying mechanisms inside the two inner tube structures are symmetrically arranged with the vertical center line of the raw material conveying pipe 2 as the axis of symmetry, and the ends of the two spiral conveying rods 14 that are close to each other are located inside the middle transition pipe 4. The two second drive motors 13 on both sides drive the two spiral conveying rods 14 to rotate counterclockwise, which can drive the raw materials injected from the feed hoppers 5 on both sides to be transported to the middle transition pipe 4 and enter the mixing tank 1 from the middle transition pipe 4.
[0024] A middle transition pipe 4, which can communicate with the inner pipe structure, is provided in the middle part of the raw material conveying pipe 2. An air blowing mechanism that can blow away fragments and dust is provided between the middle transition pipe 4 and the raw material conveying pipe 2. The air blowing mechanism includes an air pump 15, an annular pipe 16, and an air outlet pipe 17. The air pump 15 is fixedly installed on the outer surface of the middle transition pipe 4 and is located inside the raw material conveying pipe 2. The annular pipe 16 is connected to the air outlet end of the air pump 15 and is sleeved on the outside of the bottom of the middle transition pipe 4. There are two air outlet pipes 17, and the two air outlet pipes 17 are connected to the two ends of the upper surface of the annular pipe 16 and are respectively inserted into the gap between the two inner pipes 11 and the raw material conveying pipe 2. An arc-shaped outlet 18 is opened at the bottom of both ends of the raw material conveying pipe 2. The two arc-shaped outlets 18 are respectively connected to the gap between the two inner pipes 11 and the raw material conveying pipe 2 and are respectively horizontally corresponding to the two air outlet pipes 17.
[0025] After the air pump 15 is running, it can blow air outward through the air outlet pipes 17 on both sides through the annular pipe 16. The air outlet pipes 17 correspond to the parts on both sides where small particles and dust are stored. Therefore, it can blow the particles and dust between the two inner pipes 11 and the raw material conveying pipe 2 towards the end of the raw material conveying pipe 2. The arc-shaped outlets 18 at both ends of the raw material conveying pipe 2 can be connected to the external collection container. Therefore, the air blowing mechanism can continuously blow the filtered particles and dust outward, which can not only reduce the dust content in the cat litter, but also quickly clean and collect the particles and dust at the filter, making it more convenient to use when mixing cat litter.
[0026] The first drive motor 6, the second drive motor 13, and the air pump 15 are all connected to an external control unit and are electrically connected to an external circuit via wires.
[0027] In summary, the operating steps of this multi-mineral composite cat litter raw material mixing device are as follows:
[0028] 1. Different raw materials are injected into the inner tube 11 from the feed hoppers 5 on both sides, and the second drive motors 13 on both sides are run at the same time, so that the spiral conveyor rods 14 on both sides drive the raw materials to the middle transition tube 4.
[0029] 2. When the spiral conveyor rod 14 moves the raw material to the middle transition pipe 4, it will pass over the filter screen 12. The tiny particles and dust in the raw material will fall through the mesh of the filter screen 12 and into the bottom of the raw material conveying pipe 2. The air pump 15 blows air outward through the air outlet pipes 17 on both sides through the annular pipe 16, blowing the particles and dust between the two inner pipes 11 and the raw material conveying pipe 2 towards the arc-shaped outlet 18 and outward, which can clean the particles and dust.
[0030] 3. After the raw materials enter the mixing tank 1 through the conveying mechanism, the first drive motor 6 drives the active toothed plate 7 and the active screw rod 8 to rotate clockwise, which drives the raw materials on the active screw rod 8 to be conveyed upward. At the same time, the active toothed plate 7 drives the driven toothed plates 9 and the driven screw rod 10 on both sides to rotate counterclockwise, so that the two driven screw rods 10 drive the raw materials inside them to be conveyed downward. They rotate in coordination with the active screw rod 8, so that the various raw materials are mixed more evenly.
[0031] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
