Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, specifically relating to a pet bedding wood fiber crushing and cleaning device. Background Technology

[0002] The wood fibers used in pet bedding mainly include poplar fiber, wood flour, and wood chips. These materials are commonly used to make pet bedding and have characteristics such as water absorption, breathability, and environmental friendliness.

[0003] Poplar fiber is a common pet bedding material, prized for its purity, low moisture content, and low ash content. Its excellent absorbency and breathability effectively keep pets dry and comfortable. Furthermore, poplar fiber is frequently used in hamster bedding, providing good warmth and stability, ideal for hamsters' burrowing and activity.

[0004] Wood flour and wood shavings are also common pet bedding materials. They are usually made from hardwoods such as poplar and are environmentally friendly, renewable, and biodegradable. Wood flour and wood shavings can be used as raw materials for pet bedding, providing good absorbency and warmth, and are suitable for a variety of small pets.

[0005] Besides poplar fiber, wood flour, and sawdust, other types of wood fiber materials are also commonly used in pet bedding. For example, pine fiber, walnut sand, and wood pulp are also used to make pet bedding, as they have good water absorption and warmth retention properties, making them suitable for various small animals.

[0006] Existing pet bedding wood fiber crushing equipment mainly includes corn cob crushers and wood chip crushers. These devices are primarily used to crush wood fiber materials into pellets suitable for use as pet bedding.

[0007] Corn cob crushers are mainly used to crush corn cobs into smooth, polished granules. These granules can be used as pet bedding, offering advantages such as being environmentally friendly and moisture-absorbing. Wood chip crushers, on the other hand, can crush wood chips into bedding suitable for small pets like hamsters, offering advantages such as affordability and high volume discounts.

[0008] However, these devices also have some drawbacks. For example, wood shavings produce a lot of dust, which may cause respiratory discomfort; some wood shavings have a natural wood smell, which some pets may find unpleasant; the deodorizing effect is generally limited, and they may need to be used in conjunction with other cleaning methods. In addition, long-term use of wood shavings with a pungent odor may harm a pet's health. Utility Model Content

[0009] To address the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a pet bedding wood fiber crushing and cleaning device for reducing dust in finished wood fiber bedding products.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0011] A pet bedding wood fiber crushing and cleaning device includes a crushing chamber and a dust removal chamber. The crushing chamber is equipped with several sets of bidirectional rotating blades to fully cut and crush the material. The dust removal chamber is equipped with dust removal brushes in the interlayer to clean the dust removal bin and further filter the dust. The dust removal chamber is equipped with a pusher plate inside to disperse the material.

[0012] The bidirectional rotary tool set includes a clockwise rotating tool set and a counterclockwise rotating tool set.

[0013] The clockwise steering tool assembly is fixedly mounted on the clockwise steering shaft and rotates clockwise.

[0014] The counterclockwise directional cutter group is fixedly mounted on the counterclockwise directional control cylinder and rotates counterclockwise.

[0015] The pusher plate rotates relative to the dust collector to break up the material.

[0016] The dust removal brush is fixedly installed on the inner surface of the dust collection bin and is used to clean the dust collection bin and perform further filtration.

[0017] The dust collection chamber is connected to an external dust collection device, which powerfully cleans and adsorbs the dust in the inner dust collection cylinder.

[0018] The crushing chamber is raised and lowered by the crushing chamber lifting bracket and docked with the dust removal chamber.

[0019] The dust collector is uniformly equipped with sieve holes with a diameter of less than 6 mm.

[0020] The dust removal chamber is controlled by a rotating support frame to rotate less than 180°.

[0021] Compared with the prior art, the technical advantages of this utility model include:

[0022] 1) The clockwise and counterclockwise blade sets of this utility model are installed alternately on top of each other and rotate relative to each other during operation to fully cut and crush the material.

[0023] 2) During the operation of this utility model, the pusher plate and the dust collection bucket rotate relative to each other, which disperses the material and allows the dust adsorbed on the crushed wood fiber material to be fully cleaned.

[0024] 3) This utility model features a dust collection brush and an air chamber outside the dust collection bin. Dust in the inner cylinder passes sequentially through the sieve holes on the dust collection bin and the dust collection brush, and is finally adsorbed into the air chamber for recycling. When the crushed material is damp, the air heating equipment is turned on. The heated air passes sequentially through the air chamber, the dust collection brush, and the sieve holes on the dust collection bin before entering the dust collection bin to heat and dry the material. Low-temperature drying ensures that the bedding material is dry and free of mold or odor, effectively reducing dust generation while ensuring the dryness and hygiene of the bedding material.

[0033] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0034] like Figure 1-7As shown, a pet bedding wood fiber shredding and cleaning device includes: 1. Shredding chamber; 2. Dust removal chamber; 3. Dust removal chamber rotating support; 4. Shredding chamber lifting support; 5. First controller; 51. Counterclockwise drive motor; 511. Gear turntable bearing; 52. Clockwise drive motor; 6. Second controller; 11.

Pusher plate counterclockwise rotation shaft; 25. Dust removal inner cylinder; 26. Dust removal chamber sealing cover; 27. Sealing cover storage slot; 28. Air chamber.

[0035] The internal structure of the crushing chamber 1 contains several sets of wood fiber material crushing structures, with at least two sets. Each set of wood fiber material crushing structures consists of a clockwise rotating blade assembly 12 and a counterclockwise rotating blade assembly 16, which are installed alternately and rotate simultaneously during operation. The clockwise rotating blade assembly 12 is fixedly installed outside the crushing blade assembly fixed shaft (clockwise rotating shaft) 13. During operation, the clockwise drive motor 52 controls the crushing blade assembly fixed shaft (clockwise rotating shaft) 13 to rotate clockwise, and the clockwise rotating blade assembly 12 is controlled by the crushing blade assembly fixed shaft (clockwise rotating shaft) 13 to rotate clockwise. The counterclockwise rotating blade assembly 16 is sleeved on the crushing blade assembly fixed shaft (clockwise rotating shaft) 13 and is fixedly installed on the counterclockwise rotating control cylinder 15. During operation, the counterclockwise drive motor 51 controls the counterclockwise rotating control cylinder 15 to rotate counterclockwise, and the counterclockwise rotating blade assembly 16 is controlled by the counterclockwise rotating control cylinder 15 to rotate counterclockwise.

[0036] The first controller 5 is installed on the crushing chamber lifting bracket 4. The first controller 5 can simultaneously control the motor drive module and the lifting drive module. The motor drive module includes a clockwise drive motor 52 that controls the clockwise rotation of the crushing blade assembly fixed shaft (clockwise rotation shaft) 13, and a counterclockwise drive motor 51 that controls the counterclockwise rotation of the counterclockwise rotation control cylinder 15. The bottom of the counterclockwise rotation control cylinder 15 has a serrated edge, which meshes with the gear turntable bearing 511. The counterclockwise drive motor 51 drives the gear turntable bearing 511 to rotate the counterclockwise rotation control cylinder 15. The lifting drive module controls the lifting of the crushing chamber lifting bracket 4.

[0037] The crushing chamber 1 is fixedly installed on the crushing chamber lifting bracket 4. During operation, the crushing chamber lifting bracket 4 is fixed at the highest point. When the crushing work in the crushing chamber 1 is completed and needs to be connected with the dust removal chamber 2, the bracket is lowered and the dust removal chamber sealing cover 26 of the dust removal chamber 2 is retracted into the sealing cover storage slot 27. At this time, the dust removal chamber 2 is opened and connected with the crushing chamber outlet 11. The wood fiber material that has been fully crushed is discharged from the crushing chamber outlet 11 and enters the dust removal chamber 2 for further drying and dust removal.

[0038] When the dust collection chamber 2 is in operation, the dust collection bin 22 rotates clockwise, while the pusher plate 23 rotates counterclockwise relative to the dust collection bin 22. This allows the wood fiber material requiring drying and dust removal to be fully dispersed within the dust collection inner cylinder 25, ensuring that the dust adsorbed on the pulverized wood fiber material is thoroughly cleaned. Because the pet bedding prepared by this invention has a particle size between 6mm and 10mm, the dust collection bin 22 is uniformly equipped with sieve holes with a diameter of less than 6mm to allow dust to pass through, retaining only the pet bedding particles that meet the preparation requirements of this invention.

[0039] A ring of dust-collecting brushes 21 is installed on the outside of the dust collection bin 22 to clean the dust and fine particles adsorbed on the dust collection bin 22 and perform further fine filtration. The dust-collecting brushes 21 are fixedly installed on the inner surface of the air chamber 28. The air chamber 28 is connected to a dust collection device and an air heating device. During dust collection, the dust collection device is turned on to powerfully clean and adsorb the dust in the dust collection inner cylinder 25. The suction power can be adjusted according to the different material properties. The dust in the dust collection inner cylinder 25 passes through the screen holes on the dust collection bin 22 and the dust-collecting brushes 21 in sequence and is finally adsorbed into the air chamber 28 for recycling. When the crushed material is damp, the air heating device is turned on. The heated air passes through the air chamber 28, through the dust-collecting brushes 21 and the screen holes on the dust collection bin 22 in sequence, and finally enters the dust collection bin 22 to heat and dry the material.

[0040] The second controller 6 is mounted on the dust collection bin rotating bracket 3 and can simultaneously control the dust collection bin rotation module and the dust collection bin tilting module. The dust collection bin rotation module drives the dust collection bin 22 to rotate clockwise. The dust collection bin tilting module controls the dust collection bin to tilt at multiple angles (<180°). After the dust collection bin 2 finishes working, the dust collection bin rotating bracket 3, controlled by the dust collection bin tilting module, can rotate 180° as a whole, allowing the dust-collected material to be unloaded in one go.

[0041] The working principle of this utility model is as follows: The crushing chamber 1 is fixedly installed on the crushing chamber lifting support 4, and the crushing chamber lifting support 4 is fixed at the highest point during operation. The wood fiber material to be crushed is placed into the crushing chamber 1, and after being cut by the clockwise rotating blade group 12 and the counterclockwise rotating blade group in sequence, the wood fiber material is obtained after being fully crushed. When the crushing work in the crushing chamber 1 is completed and it needs to be connected with the dust removal chamber 2, the support is lowered, and the dust removal chamber sealing cover 26 of the dust removal chamber 2 is retracted into the sealing cover storage slot 27. At this time, the dust removal chamber 2 opens and connects with the crushing chamber outlet 11. The fully crushed wood fiber material is discharged from the crushing chamber outlet 11 and enters the dust removal chamber 2 for further drying and dust removal. The dust removal bucket 22 rotates clockwise, and the pusher plate 23 rotates counterclockwise with the dust removal bucket 22, so that the wood fiber material to be dried and dust removed is fully dispersed in the dust removal inner cylinder 25, so that the dust adsorbed on the crushed wood fiber material can be fully cleaned. A ring of dust-collecting brushes 21 is installed on the outside of the dust collection bin 22 to clean the dust and fine particles adsorbed on the bin and perform further fine filtration. A dust collection chamber 28 is connected to an external vacuum cleaner to powerfully clean and adsorb the dust in the inner dust collection cylinder 25; the suction power can be adjusted according to the properties of different materials. The dust in the inner dust collection cylinder 25 passes sequentially through the sieve holes and dust-collecting brushes 21 on the dust collection bin 22 and is finally adsorbed into the dust collection chamber 28 for recycling.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
