[0001] This utility model relates to the field of bamboo shavings drying and pulverizing, specifically to a high-efficiency integrated device for drying and pulverizing bamboo shavings. Background Technology

[0002] Bamboo shavings are waste materials from bamboo processing, including flakes, strips, and granules. During bamboo processing, bamboo shavings need to be crushed and dried before they can be used as fuel, boards, or papermaking raw materials.

[0003] In current bamboo processing technology, crushing and drying are carried out in separate steps, which is inefficient and energy-intensive. In addition, bamboo fibers are highly tough and easily entangle the cutting tools during crushing, leading to frequent equipment shutdowns for cleaning and reduced production efficiency. Although existing technologies have attempted to improve the cutting tool structure (such as adding serrations), they still cannot completely solve the entanglement problem. How to invent an efficient integrated device for drying and crushing bamboo chips to improve these problems has become an urgent problem for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated device for efficient bamboo chip drying and crushing, which aims to improve the current bamboo processing technology, where crushing and drying are carried out in separate steps, resulting in low efficiency and high energy consumption. In addition, bamboo fibers are highly tough and easily entangle the blades during crushing, leading to frequent machine shutdowns for cleaning and reduced production efficiency. Although existing technologies have attempted to improve the blade structure (such as adding serrations), they still cannot completely solve the entanglement problem.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an efficient bamboo shavings drying and pulverizing integrated device, including a machine body and a feeding funnel set on the machine body. A drying chamber is provided in the lower part of the machine body, and a pulverizing chamber is provided in the upper part of the machine body. A feeding plate is provided in the machine body to transport the pulverized bamboo shavings into the drying chamber. It also includes an anti-winding pulverizing mechanism: the anti-winding pulverizing mechanism is set in the pulverizing chamber, and the anti-winding pulverizing mechanism will not wind the bamboo shavings onto the blades when pulverizing the bamboo.

[0007] Preferably, the anti-entanglement crushing mechanism includes a rotating tube inside the crushing chamber. Multiple sets of connecting seats are provided on the outer wall of the rotating tube. Each connecting seat has a blade at one end, and each blade has multiple sets of serrated teeth on its sidewall. A connecting channel communicating with the rotating tube is opened inside the connecting seat. An air intake channel communicating with the connecting channel is opened inside the blade. Multiple sets of spray holes communicating with the air intake channel are opened on the sidewall of the blade. One end of the rotating tube passes through the top of the crushing chamber and connects to a rotary joint located outside. One end of the rotary joint has an air intake pipe. A fixing plate is sleeved on the outer wall of the air intake pipe. One end of the fixing plate is connected to the top of the machine body. A driven gear is sleeved on the outer wall of the rotating tube. A motor is located on the top of the machine body, and a driving gear meshing with the driven gear is connected to the output end of the motor.

[0008] Preferably, the multiple sets of nozzles are distributed in a linear array on the sidewall of the blade, and the nozzles are located in the gaps between the serrations.

[0009] Preferably, the connecting seat and the blade are integrally formed, and the blade is inclined at a 15-degree angle in the horizontal direction.

[0010] Preferably, the top of the machine body has a through hole, and a bearing is sleeved on the outer wall of the rotating tube, with the bearing cooperating with the inner wall of the through hole.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model sets the crushing chamber and drying chamber in the same machine body, eliminating the need for separate steps, resulting in high efficiency and low energy consumption. Through the internal air passage design of the blade, the air compressor delivers compressed air from the air inlet pipe to the rotating pipe, and then sprays it out from the nozzle through the connecting channel and the air inlet channel. The nozzle is located in the gap between the serrations, so that the nozzle is directly aligned with the gap between the serrations. As a result, the airflow sprayed from the nozzle immediately blows away the entangled fibers, solving the problem of bamboo fiber entanglement, reducing the number of downtime cleanings, and achieving high efficiency.

[0013] 2. This utility model arranges the blades horizontally at a 15-degree angle, thereby enhancing the shearing force of the material and improving the crushing effect when the blades rotate to crush bamboo. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example, refer to Figures 1-4 A high-efficiency bamboo shavings drying and pulverizing integrated device includes a body 1 and a feeding funnel 6 installed on the body 1. A drying chamber 2 is provided in the lower part of the body 1. A heater is provided on the rear side wall of the body 1. After the heater heats the air, the hot air is circulated to the drying chamber 2 by a fan (this is prior art and will not be described in detail here). It is suitable for large-scale continuous production, thereby drying bamboo shavings. A feeding pipe connected to the drying chamber 2 is provided through the side wall of the body 1 to facilitate the feeding of dried bamboo shavings. A pulverizing chamber 4 is provided in the upper part of the body 1. A feeding plate 3 is provided in the body 1 to transport the pulverized bamboo shavings into the drying chamber 2. It also includes an anti-winding pulverizing mechanism 5: the anti-winding pulverizing mechanism 5 is installed in the pulverizing chamber 4. The anti-winding pulverizing mechanism 5 will not wind up the blade 501 when pulverizing bamboo.

[0022] The anti-tangling crushing mechanism 5 includes a rotating tube 500 inside the crushing chamber 4. Multiple sets of connecting seats 508 are provided on the outer wall of the rotating tube 500. Each connecting seat 508 has a blade 501 at one end. The sidewall of each blade 501 has multiple sets of serrations 510. A connecting channel 511 communicating with the rotating tube 500 is opened inside the connecting seat 508. An air inlet channel 509 communicating with the connecting channel 511 is opened inside the blade 501. Multiple sets of spray holes 512 communicating with the air inlet channel 509 are opened on the sidewall of the blade 501. One end of the rotating tube 500 penetrates the top of the crushing chamber 4 and connects to the outer wall of the rotating tube 500. Some rotary joints 506 are connected, and a through hole is opened at the top of the machine body 1. A bearing is sleeved on the outer wall of the rotating tube 500. The bearing cooperates with the inner wall of the through hole. Under the action of the bearing, the rotating tube 500 rotates more stably. One end of the rotary joint 506 is provided with an air inlet pipe 507. A fixing plate 504 is sleeved on the outer wall of the air inlet pipe 507. One end of the fixing plate 504 is connected to the top of the machine body 1. A driven gear 505 is sleeved on the outer wall of the rotating tube 500. A motor 502 is provided at the top of the machine body 1. The output end of the motor 502 is connected to a driving gear 503 that meshes with the driven gear 505.

[0023] It should be noted that the rotating tube 500 is installed in the top through hole of the machine body through the bearing, and the bottom is suspended in the crushing chamber 4. The air inlet pipe 507 is connected to an air compressor, which can deliver compressed air to the inner wall of the rotating tube 500. The outer wall of the rotating tube 500 has an opening, which is connected to the connecting channel 511.

[0024] Multiple sets of nozzles 512 are linearly arrayed on the sidewall of the blade 501, and the nozzles 512 are located in the gaps between the teeth 510.

[0025] It should be noted that the nozzle 512 is located in the gap between the teeth 510, so that when the airflow is sprayed, it can ensure that the airflow covers the working surface of the teeth 510, and the continuous spraying of airflow can prevent entanglement.

[0026] The connector 508 and the blade 501 are integrally formed, and the blade 501 is set at a 15-degree tilt angle in the horizontal direction.

[0027] It should be noted that the cutting tool 501 is welded to the rotating tube 500 via the connecting seat 508 and is tilted at 15 degrees to improve cutting efficiency.

[0028] Working principle: Bamboo enters the crushing chamber 4 through the feeding hopper 6. The motor 502 drives the drive gear 503 to rotate, which in turn drives the driven gear 505 to rotate. The driven gear 505 drives the rotating tube 500 to rotate at high speed, which in turn drives the blades 501 and the saw teeth 510 to cut and crush the bamboo into bamboo chips. The air compressor delivers compressed air to the rotating tube 500 through the air inlet pipe 507, and then delivers it to the nozzle 512 through the connecting channel 511 and the air inlet channel 509. Finally, the compressed air is ejected at high speed from the nozzle 512. The airflow acts directly on the gaps between the saw teeth 510, instantly blowing away the bamboo fibers attached to the blades 500 and completely preventing entanglement. The crushed bamboo chips fall into the drying chamber 2 through the feeding plate 3. After the external heater heats the air, the hot air is circulated to the drying chamber 2 by the fan to dry the bamboo chips evenly. The dried bamboo chips are discharged from the feeding pipe.

[0029] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
