Description

Technical Field

[0001] This utility model belongs to the technical field of straw cutting equipment, specifically referring to a straw cutting equipment for biofuel preparation. Background Technology

[0002] In the process of biofuel production, straw is an important raw material that needs to be cut to meet the needs of subsequent processing. The cutting method of straw cutting equipment is crucial. The common cutting method is to achieve reciprocating cutting action by extending and retracting hydraulic cylinders.

[0003] Hydraulic cylinder drive systems require complex hydraulic pump stations, which are costly. Hydraulic oil is prone to leakage, which not only pollutes the environment but also requires regular maintenance and replenishment of hydraulic oil. In addition, the response speed of hydraulic cylinders is relatively slow, making it difficult to meet the needs of high-speed cutting operations. Utility Model Content

[0004] The technical problem this invention aims to solve is that the hydraulic cylinder drive method for straw cutting equipment is costly, prone to hydraulic oil leakage, polluting the environment and requiring regular maintenance and replenishment of hydraulic oil. Furthermore, the hydraulic cylinder's response speed is relatively slow, making it difficult to meet the demands of high-speed cutting operations.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A straw cutting device for biofuel preparation includes a support box and a cutter. The top wall of the support box is provided with a groove, and the side wall is provided with a discharge port. The side of the support box away from the discharge port is set with an open structure. The bottom of the discharge port is provided with a guide seat. The bottom of the cutter is slidably disposed on the groove and located above the guide seat. The top wall of the support box is provided with a driving component for driving the cutter to move.

[0006] Preferably, the driving component includes a turntable and a drive motor. The top wall of the support box is provided with a bracket, the inner side wall of the bracket is provided with a slide rail, the top of the cutter is slidably mounted on the slide rail, the top of the cutter is provided with a groove, the side wall of the top of the bracket is provided with a support, the turntable is rotatably mounted on the support, the support is provided with a drive motor that drives the turntable to rotate, and the eccentric part of the turntable is provided with a protrusion, which is slidably mounted in the groove.

[0007] Preferably, the support box is provided with pressure rollers arranged in parallel at the top and bottom near the discharge port, with the top of the lower pressure roller on the same horizontal line as the top of the belt conveyor, and one side of the guide seat is tangent to the rolling of the lower pressure roller.

[0008] Preferably, the inner sidewalls of the support box near the opening are provided with baffles, and a belt conveyor is provided between the baffles.

[0009] Preferably, the support box has a guide plate at its inner top, and the bottom end of the guide plate is close to the bottom of the pressure roller.

[0010] Preferably, the support is provided with a housing that covers the drive motor.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. The use of a turntable and drive motor to drive the equipment instead of the traditional hydraulic cylinder drive eliminates the need for complex hydraulic pump stations, oil tanks, oil pumps and various hydraulic control valves, greatly reducing the initial purchase cost of the equipment. It also eliminates the need for expensive hydraulic components such as high-pressure oil pipes and seals required by the hydraulic system, thus reducing the overall cost of the equipment.

[0013] 2. Since hydraulic oil is no longer used as the power transmission medium, the risk of hydraulic oil leakage is eliminated, avoiding environmental pollution and meeting environmental protection requirements. It also avoids the problem of the quality of biofuel being affected by hydraulic oil leakage, ensuring the cleanliness of the biofuel production process and the quality of the products.

[0014] 3. The drive motor drives the turntable to rotate, causing the protrusions on the turntable to slide in the grooves of the cutter, thereby realizing the reciprocating motion of the cutter. This drive method can realize the rapid start and stop of the cutter, meet the needs of high-speed cutting operations, and significantly improve the efficiency of straw cutting.

The utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, the present invention proposes a straw cutting device for biofuel preparation, including a support box 1 and a cutter 2. The top wall of the support box 1 is provided with a groove 3, and the side wall is provided with a discharge port 4. The side of the support box 1 away from the discharge port 4 is an open structure. The bottom of the discharge port 4 is provided with a guide seat 5. The bottom of the cutter 2 is slidably mounted on the groove 3 and located above the guide seat 5. The top wall of the support box 1 is provided with a driving member 6 for driving the cutter 2. When straw is fed into the opening, the driving member 6 drives the cutter 2 to move up and down reciprocally to cut the straw into segments.

[0023] like Figure 1-3 As shown, the driving component 6 includes a turntable 7 and a drive motor 12. The top wall of the support box 1 is provided with a bracket 8, and the inner side wall of the bracket 8 is provided with a slide rail 9. The top of the cutter 2 is slidably mounted on the slide rail 9. The top of the cutter 2 is provided with a groove 10. The side wall of the top of the bracket 8 is provided with a support 11. The turntable 7 is rotatably mounted on the support 11. The support 11 is provided with a drive motor 12 that drives the turntable 7 to rotate. The support 11 is provided with a housing 18 that covers the drive motor 12. The eccentric part of the turntable 7 is provided with a protrusion 13. The protrusion 13 is slidably mounted in the groove 10. When the drive motor 12 is started, the turntable 7 is driven to rotate. The protrusion 13 on the turntable 7 slides in the groove 10 to drive the cutter 2 to reciprocate up and down cutting motions.

[0024] like Figure 2 and 4As shown, the support box 1 is provided with pressure rollers 14 arranged vertically and horizontally near the discharge port 4. The top of the lower pressure roller 14 is on the same horizontal line as the top of the belt conveyor 16. One side of the guide seat 5 is tangential to the lower pressure roller 14. The inner top of the support box 1 is provided with a guide plate 17. The bottom end of the guide plate 17 is close to the bottom of the pressure roller 14. The straw fed in is guided between the two pressure rollers 14 for sorting through the guide plate 17.

[0025] like Figure 4 As shown, baffles 15 are arranged opposite each other on the inner side wall of the support box 1 near the opening. A belt conveyor 16 is provided between the baffles 15. When straw is placed on the belt conveyor 16, the belt conveyor 16 feeds the straw between the two pressure rollers 14 for sorting. Under the continuous conveying of the belt conveyor 16, the straw is further fed to the guide seat 5, where the cutter 2 cuts it and the straw continuously fed from behind is discharged from the discharge port 4.

[0026] In practical use, the straw is placed on the belt conveyor 16 through the opening of the support box 1, and the belt conveyor 16 is started. The conveyor belt transports the straw between the two pressure rollers 14.

[0027] The belt conveyor 16 continuously feeds the straw to the pressure roller 14. During this process, the guide plate 17 located at the top of the support box 1 guides the fed straw between the two pressure rollers 14. The pressure rollers 14 arranged in parallel make the straw more neat and facilitate subsequent cutting operations.

[0028] Start the drive motor 12, and the motor drives the turntable 7 to rotate on the support 11. Since the convex post 13 at the eccentric part of the turntable 7 is slidably set in the groove 10 of the cutter 2, the rotation of the turntable 7 will cause the convex post 13 to slide in the groove 10, thereby driving the cutter 2 to move back and forth up and down on the slot 3 and slide rail 9 on the top wall of the support box 1.

[0029] During the up-and-down movement of the cutter 2, the straw passing through the guide seat 5 is cut into segments. At this time, the straw is orderly fed to the bottom of the cutter 2 under the guidance of the pressure roller 14 and the conveyor belt 16, ensuring the accuracy and continuity of the cutting. The cut straw is partially slid out directly from the discharge port 4, and partially discharged from the discharge port 4 on the side wall of the support box 1 under the push of the continuously fed straw from behind, realizing the continuous operation of straw cutting and discharge.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
