Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuels, and particularly relates to a full-automatic cutting device for biomass fuels. Background Technique

[0002] Biomass fuel refers to using biomass materials as fuel, generally mainly agricultural and forestry waste. In practical applications, the application form of biomass fuel is mainly biomass briquette fuel, that is, using agricultural and forestry waste as raw materials, through processes such as crushing, mixing, extrusion, and drying, to make various formed and directly combustible new clean fuels.

[0003] A Chinese patent with the publication number CN218785649U discloses a full-automatic cutting device for biomass fuels, including: a housing, support feet, a collection box, a first guide plate, a bottom plate, a second guide plate, a pushing and cutting member, a clamping member, and a protection member; a bottom plate is fixedly installed at the upper end of the housing, a second guide plate is fixedly installed at the front end of the bottom plate, a pushing and cutting member is fixedly installed at the middle position of the upper surface of the bottom plate, and the electric cylinder in the pushing and cutting member pushes to drive the push plate fixedly installed at the output end of the electric cylinder to cut off the biomass fuel. When the push plate cuts off, the contact area with the biomass fuel is large. According to the relatively brittle characteristics of the whole biomass fuel, it is broken with the assistance of the clamping member, which can avoid the cracking of the biomass fuel and the generation of a large amount of waste, improve the utilization rate of the biomass fuel, and an infrared sensor is movably installed inside the protective shell of the protection member. Adjusting the position of the outer line sensor can change the length of the biomass fuel after cutting, meeting the needs of users for biomass fuels of different lengths.

[0004] As described above, this patent provides a full-automatic cutting device for biomass fuels, which can improve the utilization rate of biomass fuels and meet the needs of users for biomass fuels of different lengths. However, after cutting, it is impossible to collect the cut biomass fuel, resulting in room for improvement in the overall cutting work efficiency. Content of the Utility Model

[0006] To solve the above problems, the present utility model provides a fully automatic biomass fuel cutting device, including support legs, a workbench and a feeding component. The feeding component includes a limiting plate and a cutting placement plate. One side of the cutting placement plate is fixedly connected with a T-shaped sliding plate. A sliding wheel is rotatably connected to the surface of the T-shaped sliding plate. A T-shaped card slot adapted to the T-shaped sliding plate is opened on one side of the workbench. A sliding card rail adapted to the sliding wheel is opened on one side of the inner wall of the T-shaped card slot. A sliding card table is fixedly connected to the surface of the cutting placement plate away from the T-shaped sliding plate. The surface of the sliding card table is slidably connected to one side of the workbench. A reciprocating lead screw is threadedly connected to the surface of the sliding card table. A connecting support rod is fixedly connected to the surface of the limiting plate. One end of the connecting support rod away from the limiting plate is fixedly connected to the surface of the workbench. A blanking port is opened at the bottom of the workbench and on one side of the limiting plate.

[0007] Preferably: An installation frame is fixedly connected to the top of the workbench. An electric telescopic rod and a spring telescopic rod are respectively fixedly connected to the bottom of the installation frame. The number of the spring telescopic rods is set to two, and the two spring telescopic rods are symmetrically arranged on both sides of the electric telescopic rod. The bottom end of the electric telescopic rod is fixedly connected with a lifting plate. The top of the lifting plate is fixedly connected with the bottom ends of the two spring telescopic rods. A cutting knife is fixedly connected to one side of the bottom of the lifting plate. A sliding clamping rod is slidably connected to the surface of the lifting plate away from the cutting knife.

[0008] Preferably: One end of the sliding clamping rod penetrates through the lifting plate and extends to the bottom of the lifting plate. A pressing plate is fixedly connected to the end of the sliding clamping rod located at the bottom of the lifting plate. A limiting spring is sleeved on the surface of the sliding clamping rod located at the bottom of the lifting plate. The two ends of the limiting spring are respectively fixedly connected with the top of the lifting plate and the top of the pressing plate. The number of the sliding clamping rods is set to three, and the three sliding clamping rods are evenly arranged at equal distances on the surface of the lifting plate.

[0009] Preferably: A rotating frame is fixedly connected to one side of the workbench. Both ends of the reciprocating lead screw are rotatably connected to the surface of the rotating frame. A motor frame is fixedly connected to one side of the workbench. A motor is fixedly connected to the inside of the motor frame. The output shaft of the motor is fixedly connected with one end of the reciprocating lead screw through a coupling.

[0010] Preferably: The top end of the support leg is fixedly connected to the bottom of the workbench. A connecting cross bar is fixedly connected to the surface of the support leg. A receiving bin is movably connected to the top of the connecting cross bar and at the bottom of the blanking port.

[0011] The beneficial effects of adopting the above technical solutions are:

[0012] 1. By setting up the blanking component, during operation, the biomass fuel is placed on the top of the cutting placement plate for cutting. After cutting, the reciprocating screw rotates to drive the sliding table to start moving, thereby driving the cutting placement plate to slide. On the other side of the cutting placement plate, a T-shaped sliding plate is fixed, and the T-shaped sliding plate is inserted into the T-shaped card slot, enabling the cutting placement plate to slide in the T-shaped card slot through the T-shaped sliding plate. At the same time, a sliding wheel is rotatably connected to the surface of the T-shaped sliding plate, and the sliding wheel slides in the sliding track, thus ensuring the smoothness of the sliding of the cutting placement plate. When the cutting placement plate completely covers the material falling opening, the biomass fuel cut on its top starts to abut against the limiting plate. As the cutting placement plate continues to slide, the limiting plate pushes the biomass fuel out of the cutting placement plate and then falls from the material falling opening, realizing the function of automatic material collection and improving the efficiency of the cutting work.

[0013] 2. By fixing a cutting knife on one side of the lifting plate to cut the biomass fuel, and at the same time, a sliding clamping rod is arranged on the other side of the lifting plate. A limiting spring is sleeved on the surface of the sliding clamping rod, and a pressing plate is fixed at the bottom end. Then, the limiting spring supports the pressing plate and the sliding clamping rod, and the height of the pressing plate is slightly lower than the height of the cutting knife. It can contact and abut against the surface of the biomass fuel before cutting, so as to limit the biomass fuel during cutting and ensure the stability during cutting, further improving the adaptability of the cutting work.

[0022] As Figure 1 - Figure 4 shown, in this embodiment, a fully automatic biomass fuel cutting device includes support legs 1, a workbench 2 and a blanking assembly. The blanking assembly includes a limiting plate 3 and a cutting placement plate 4; one side of the cutting placement plate 4 is fixedly connected with a T-shaped sliding plate 5; a sliding wheel 6 is rotatably connected to the surface of the T-shaped sliding plate 5; a T-shaped slot 7 adapted to the T-shaped sliding plate 5 is opened on one side of the workbench 2; a sliding rail 8 adapted to the sliding wheel 6 is opened on one side of the inner wall of the T-shaped slot 7; a sliding table 9 is fixedly connected to the surface of the cutting placement plate 4 away from the T-shaped sliding plate 5; the surface of the sliding table 9 is slidably connected to one side of the workbench 2; a reciprocating lead screw 10 is threadedly connected to the surface of the sliding table 9; a connecting support rod 11 is fixedly connected to the surface of the limiting plate 3; one end of the connecting support rod 11 away from the limiting plate 3 is fixedly connected to the surface of the workbench 2; a blanking port 12 is opened at the bottom of the workbench 2 and on one side of the limiting plate 3.

The blanking port 12 is used for blanking the cut biomass fuel. The limiting plate 3 is arranged at a position slightly deviated from the blanking port 12 and flush with it. The cutting placement plate 4 is used for placing the biomass fuel. The T-shaped sliding plate 5 and the sliding clamping platform 9 are both fixed on the cutting placement plate 4. The sliding clamping platform 9 is threadedly connected to the reciprocating lead screw 10. After the reciprocating lead screw 10 rotates, it can drive the sliding clamping platform 9 to move. The T-shaped card slot 7 is opened on one side of the workbench 2 and is adapted to the T-shaped sliding plate 5 to limit the T-shaped sliding plate 5. The sliding rail 8 is opened on the inner wall of the T-shaped card slot 7 to facilitate the sliding of the sliding wheel 6. During work, the biomass fuel is placed on the top of the cutting placement plate 4 for cutting. After cutting, the reciprocating lead screw 10 rotates to drive the sliding clamping platform 9 to start moving, thereby driving the cutting placement plate 4 to slide. The other side of the cutting placement plate 4 is fixedly connected with the T-shaped sliding plate 5. The T-shaped sliding plate 5 is clamped into the T-shaped card slot 7, so that the cutting placement plate 4 slides in the T-shaped card slot 7 through the T-shaped sliding plate 5. At the same time, the sliding wheel 6 is rotatably connected to the surface of the T-shaped sliding plate 5, and the sliding wheel 6 slides in the sliding rail 8, thereby ensuring the smooth sliding of the cutting placement plate 4.

The bottom ends of the electric telescopic rod 14 and the spring telescopic rod 15 are fixedly connected to the lifting plate 16, so that the electric telescopic rod 14 drives the lifting plate 16 to move up and down, and the spring telescopic rod 15 expands and contracts accordingly when the lifting plate 16 moves up and down, thereby limiting the lifting plate 16. A cutting knife 17 is fixed on one side of the lifting plate 16 to cut the biomass fuel. At the same time, a sliding clamping rod 18 is arranged on the other side of the lifting plate 16. A limiting spring 20 is sleeved on the surface of the sliding clamping rod 18, and a pressing plate 19 is fixed at the bottom end.

At the same time, a motor bracket 22 is fixed on one side of the workbench 2 and is used to support and mount the motor 23. When the motor 23 works, it drives the reciprocating lead screw 10 to rotate through the output shaft, so that the reciprocating lead screw 10 can drive the sliding table 9 to move reciprocally to realize the automatic feeding of the biomass fuel. In addition, the top end of the support leg 1 is fixed to the bottom of the workbench 2, and the support leg 1 supports the workbench 2.
