Description

Technical Field

[0001] This utility model relates to the field of bamboo charcoal processing technology, specifically to a raw material screening device for bamboo charcoal production. Background Technology

[0002] Bamboo charcoal is a porous carbonaceous material made from bamboo through high-temperature oxygen-free carbonization. Its unique physical structure and chemical composition endow it with multiple functions such as adsorption, humidity regulation, purification, and health care, demonstrating its wide application value in environmental management, healthy living, and agricultural improvement.

[0003] According to patent number 201721470963.3 published on the China Patent Network, this utility model discloses a screening device for bamboo charcoal processing, including a machine body. A feeding hopper is connected to the top of the machine body. An ash storage box is movably installed on the left side of the machine body. A fan is fixedly installed on the left side of the top of the machine body. The fan's outlet pipe is connected to the top of the ash storage box. The fan's inlet pipe passes through the machine body and extends into the interior of the machine body, connecting to a connecting pipe. A dust suction head is connected to the bottom of the connecting pipe. A movable plate is arranged on the left side of the inner cavity of the machine body, and a screen box is fixedly installed on the right side of the movable plate. This utility model, through the arrangement of the movable plate and the screen box, can ensure the stability of the screen box during back-and-forth swaying. (The last sentence appears to be incomplete and possibly refers to a different device.) The setup of the moving trough, movable block, connecting rod, motor, and turntable allows the turntable and connecting rod to drive the movable block and screen box to shake, thus screening bamboo charcoal powder. This solves the problem of ineffective screening of impurities in bamboo charcoal powder, which affects the processing quality of bamboo charcoal. However, current screening machines place the material basket directly below the discharge port during the receiving stage, causing material to accumulate on one side. Since the discharge port position is not adjustable, the bamboo charcoal raw material concentrates on one side of the basket under gravity, forming a significant slope and thickness difference. Users need to frequently shake the basket manually to force the material to flatten, which not only significantly increases the labor burden but also reduces the practicality of the screening machine.

[0004] Therefore, the screening machine needs to be improved to prevent the phenomenon of one-sided accumulation that is easy to occur when the receiving frame is fixed, which requires the user to shake the frame frequently. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the raw material screening device for bamboo charcoal production provided by this utility model includes a screening machine 1;

[0023] A support plate 2 is fixedly connected to the bottom of the front side of the screening machine 1. A transmission groove 3 is opened inside the support plate 2. A first rotating wheel 4 is set inside the transmission groove 3. An installation plate 5 is fixedly connected to the left side of the inner wall of the screening machine 1. A motor 6 is fixedly connected to the top of the installation plate 5. A second rotating wheel 7 is fixedly connected to the output end of the motor 6. The first rotating wheel 4 and the second rotating wheel 7 are connected by a belt. The bottom of the first rotating wheel 4 extends into the interior of the support plate 2 and is movably connected to the inner wall of the support plate 2 through a bearing. A traction rod 8 is fixedly connected to the left side of the top of the first rotating wheel 4. A movable frame 9 located at the top of the first rotating wheel 4 is slidably connected inside the transmission groove 3. The top of the traction rod 8 extends into the interior of the movable frame 9 and is slidably connected to the inner wall of the movable frame 9. A connecting block 10 is fixedly connected to the top of the movable frame 9. The top of the connecting block 10 extends through to the top of the support plate 2 and is fixedly connected to a limit frame 11.

[0024] refer to Figure 2 A protective pad 12 is fixedly connected to the rear side of the inner wall of the limiting frame 11. A pressing plate 13 is provided on the front side of the inner wall of the limiting frame 11. The surface of the pressing plate 13 is slidably connected to the inner wall of the limiting frame 11. A screw 14 is movably connected to the front side of the pressing plate 13 through a bearing. The rear side of the screw 14 extends through to the outside of the limiting frame 11 and is fixedly connected to a rotating block 15. The screw 14 is threadedly connected to the limiting frame 11.

[0025] As a technical optimization of this utility model, by setting up a protective pad 12, an extrusion plate 13, a screw 14 and a rotating block 15, the material frame can be limited, preventing the material frame from detaching from the limiting frame 11 when it shakes inside the limiting frame 11.

[0026] refer to Figure 2 The surface of the rotating block 15 is provided with anti-slip texture 16, which is used in conjunction with the rotating block 15.

[0027] As a technical optimization of this utility model, by setting anti-slip texture 16, it is easier for the user to rotate the rotating block 15 and avoid the user from slipping when rotating the rotating block 15.

[0028] refer to Figure 3 The transmission groove 3 has two guide rods 17 fixedly connected laterally inside. The guide rods 17 pass through the movable frame 9 and are slidably connected to the movable frame 9.

[0029] As a technical optimization of this utility model, by setting the guide rod 17, the moving frame 9 can be guided to prevent the moving frame 9 from tilting and getting stuck when moving.

[0030] refer to Figure 3 Both sides of the guide rod 17 are fitted with anti-pressure pads 18, and the outer side of the anti-pressure pads 18 is fixedly connected to the inner wall of the transmission groove 3.

[0031] As a technical optimization of this utility model, by setting the anti-pressure pad 18, the moving frame 9 can be protected to prevent the surface of the moving frame 9 from colliding with the inner wall of the moving groove.

[0032] refer to Figure 4 A protective sleeve 19 is fitted on the surface of the traction rod 8, and the surface of the protective sleeve 19 is in contact with the inner wall of the moving frame 9.

[0033] As a technical optimization of this utility model, by setting the protective sleeve 19, the traction rod 8 can make closer contact with the inner wall of the moving frame 9, thereby increasing the contact area between the traction rod 8 and the moving frame 9.

[0034] The working principle and usage process of this utility model are as follows: First, place the material frame inside the limiting frame 11. After placement, rotate the rotating block 15. The rotating block 15 drives the screw 14 to rotate. When the screw 14 rotates, it pushes the extrusion plate 13 to move backward, pressing the extrusion plate 13 firmly onto the surface of the material frame. After pressing, start the motor 6. The output end of the motor 6 drives the second rotating wheel 7 to rotate. The second rotating wheel 7 drives the first rotating wheel 4 to rotate via a belt. The first rotating wheel 4 drives the traction rod 8 to rotate. When the traction rod 8 rotates, it pulls the moving frame 9 to move back and forth. The moving frame 9 drives the connecting block 10 to move back and forth. The connecting block 10 drives the limiting frame 11 to move back and forth, causing the moving frame 9 to move the material frame back and forth. Finally, start the screening machine 1, allowing the screened bamboo charcoal raw materials to fall into the inside of the material frame and spread evenly. When the material frame is full, reverse the above operation to remove the material frame.

[0035] In summary, this raw material screening device for bamboo charcoal production, through the installation of a second rotating wheel 7, a traction rod 8, a moving frame 9, a connecting block 10, and a limiting frame 11, can drive the material frame to move back and forth, preventing material from accumulating on the same side. The motor 6 and the second rotating wheel 7 enable automatic rotation of the second rotating wheel 7, improving user comfort. The protective pad 12, pressure plate, screw 14, and rotating block 15 limit the material frame, preventing it from detaching from the limiting frame 11 during movement. This facilitates uniform material accumulation and solves the problem of current screening machines where the material basket is placed directly below the discharge port during the receiving stage, leading to one-sided material accumulation. Because the discharge port position is not adjustable, the bamboo charcoal raw materials concentrate on one side of the basket under gravity, creating a significant slope and thickness difference. Users must frequently manually shake the basket to force the material to flatten, which significantly increases manpower and reduces the practicality of the screening machine.
