Description

Technical Field

[0001] The invention relates to the technical field of straw fuel pellet machines, in particular to a crop straw fuel pellet machine. Background Art

[0002] The straw fuel pellet machine adopts the principle of interaction between the extrusion force and friction force between the pressing wheel and the mold to shape the material. No additives or adhesives are needed in the processing of the material. Straw and other materials contain a certain amount of cellulose and lignin. Lignin is a structural monomer in the material and a phenylpropane-type polymer compound. It has the function of strengthening the cell wall and bonding cellulose. When the temperature reaches a certain value, the lignin softens and the bonding force increases. Under a certain pressure, the cellulose molecular clusters are dislocated, deformed, and extended, and the adjacent biomass particles inside are meshed with each other, recombined and pressed into shape.

[0003] A Chinese patent application with patent application number CN202010859032.2 discloses a crop straw fuel pellet machine. Although this application achieves rapid cooling of pellet materials after processing, thereby improving the centralized processing efficiency of pellet materials after processing, when this application is put into use, the pellets fall and collide when they fall, causing them to break, thereby reducing the overall integrity of the pellets. Improvements are needed to address this problem. Summary of the invention

When the lifting cylinder moves up and down, it drives the driven frame and the moving frame to move through the fixed frame and the telescopic connecting rod.

[0010] According to the above technical solution, it also includes an injection assembly, which is composed of a pressing plate, an air bag, a connecting pipe and an injection head.

[0011] The pressure plate is fixedly connected to the outer bottom of the lifting cylinder and is staggered with the fixing frame. The airbag is fixedly connected to the inner bottom of the fixed disc. The connecting pipe is fixedly connected to the outer side of the airbag. The nozzle is arranged on the inner wall of the driving box. The air in the airbag can be sprayed out through the connecting pipe and the nozzle.

[0012] According to the above technical solution, circular grooves for accommodating the movement of the telescopic end of the electric telescopic rod are provided on the top of the protection box, the bottom of the drive box and the middle of the fixed disc. The telescopic end of the electric telescopic rod passes through the circular groove and extends to the top of the circular groove and the bottom of the lifting cylinder. The electric telescopic rod can push the lifting cylinder when working.

[0013] According to the above technical solution, the driven frame, the movable frame and the rotating pulley are all built into the movable fixed groove, and the bottom of the rotating pulley is in contact with the top of the damping pad, the rotating pulley is slidably connected to the top of the damping pad, and guide grooves are provided on the front and back inner walls of the movable fixed groove.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. When the crop straw pellet machine is required to granulate, the pellets fall into the drive box through the straw pellet granulator. At this time, the electric telescopic rod is controlled to work so that when the pellets fall, the stroke of the pellets can be reduced to prevent the pellets from breaking and being damaged due to a long falling stroke;

[0018] 2. When the particles fall on the top of the screening plate and accumulate, the weight on the top of the screening plate increases, the positioning suction cup separates from the adsorption plate, and the screening plate shakes up and down, so that the particles accumulated on the screening plate can be screened;

[0019] 3. By setting a counterweight, the weight of the screening disc close to the discharge trough is heavier. When the screening disc is shaken, the screening disc can be shaken obliquely to move the particles on the top of the screening disc obliquely and make the particles fall into the discharge trough;

[0020] 4. The force generated by the up and down shaking of the screening disc when it is subjected to force is weakened by rotating the pulley to slide on the top of the damping pad, so as to buffer the force of the screening disc rising and falling, so that the device can buffer the force when the screening disc falls when in use, and avoid the screening disc shaking up and down too fast to repeatedly hit the particles on the top of the screening disc, thereby avoiding damage to the particles;

[0021] 5. When the screening plate shakes up and down, the particles are impacted by the air sprayed from the jet head in the air, which can clean the dust adhering to the surface of the particles and ensure the particle forming efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] For example, see Figure 1-9The present invention provides a technical solution: a crop straw fuel pellet machine, including a fixed machine base 1, and also includes a lifting component 6, a protection box 2 is fixedly connected to the middle of the top of the fixed machine base 1, a driving box 3 is fixedly connected to the top of the protection box 2, a straw pellet granulator 4 is arranged on the top of the driving box 3, and a discharge chute 5 is fixedly connected to the outer side of the driving box 3.

[0037] Wherein, the lifting assembly 6 comprises:

[0038] An electric telescopic rod 601 is fixedly connected to the middle of the top of the protective box 2. The electric telescopic rod 601 has a telescopic end. A fixed disc 602 is fixedly connected to the bottom of the driving box 3. A spring 603 is fixedly connected to the top of the fixed disc 602. A screening disc 604 is fixedly connected to the top of the spring 603. Positioning suction cups 605 are fixedly connected to the front and back sides of the top of the screening disc 604. An adsorption plate 606 is fixedly connected to the inner wall of the top front and back of the driving box 3. A counterweight block 607 is fixedly connected to the left side of the bottom of the screening disc 604. The spring 603 can support the screening disc 604.

[0039] It also includes a buffer assembly 7, which consists of a lifting cylinder 701, a fixed frame 702, a telescopic connecting rod 703, a driven frame 704, a moving frame 705, a rotating pulley 706, a moving fixed groove 707 and a damping pad 708.

[0040] The lifting cylinder 701 is fixedly connected to the middle of the bottom of the screening plate 604, the fixed frame 702 is fixedly connected to the outer bottom of the lifting cylinder 701, the telescopic connecting rod 703 is rotatably connected to the middle part of the fixed frame 702, the driven frame 704 is rotatably connected to the side of the telescopic connecting rod 703 away from the fixed frame 702, the moving frame 705 is fixedly connected to the bottom of the driven frame 704, the rotating pulley 706 is rotatably connected to the inner bottom of the moving frame 705, the moving fixed groove 707 is fixedly connected to the top of the fixed disc 602, and the damping pad 708 is fixedly connected to the inner bottom of the moving fixed groove 707. When the lifting cylinder 701 moves up and down, it drives the driven frame 704 and the moving frame 705 to move through the fixed frame 702 and the telescopic connecting rod 703.

[0041] Circular grooves for accommodating the movement of the telescopic end of the electric telescopic rod 601 are provided on the top of the protective box 2, the bottom of the driving box 3 and the middle of the fixed disc 602. The telescopic end of the electric telescopic rod 601 passes through the circular groove and extends to the top of the circular groove and the bottom of the lifting cylinder 701. The electric telescopic rod 601 can push the lifting cylinder 701 when working.

[0042] The driven frame 704, the movable frame 705 and the rotating pulley 706 are all built into the movable fixed groove 707, and the bottom of the rotating pulley 706 is in contact with the top of the damping pad 708, and the rotating pulley 706 is slidably connected to the top of the damping pad 708. Guide grooves are provided on the front and back inner walls of the movable fixed groove 707, and a rotating rod is provided in the middle of the rotating pulley 706. The front and rear ends of the rotating rod are slidably connected to the inner wall of the guide groove, and the rotating pulley 706 is slidably connected to the guide groove through the rotating rod.

[0043] There are four fixed frames 702, telescopic connecting rods 703, driven frames 704, mobile frames 705, rotating pulleys 706, mobile fixed grooves 707 and damping pads 708. The four fixed frames 702, telescopic connecting rods 703, driven frames 704, mobile frames 705, rotating pulleys 706, mobile fixed grooves 707 and damping pads 708 are distributed in a ring on the outside of the lifting cylinder 701. By setting four rotating pulleys 706 to slide on the top of the damping pads 708, the force of the up and down shaking of the screening plate 604 can be converted into the resistance of the rotating pulleys 706 sliding on the top of the damping pads 708.

[0044] When the crop straw pellet machine needs to carry out granulation, the pellets fall into the drive box 3 through the straw pellet granulator 4. At this time, the electric telescopic rod 601 is controlled to work, so that the telescopic end of the electric telescopic rod 601 pushes the jacking cylinder 701 on the lower side of the screening plate 604, so that the spring 603 on the lower side of the screening plate 604 is stretched, and at the same time, the screening plate 604 rises in the drive box 3, so that the positioning suction cup 605 on the screening plate 604 contacts the bottom of the adsorption plate 606, so that the positioning suction cup 605 is adsorbed on the bottom of the adsorption plate 606, and the positioning suction cup 605 can be supported. At the same time, the distance between the screening plate 604 and the bottom of the straw pellet granulator 4 is reduced, so that when the pellets fall, the falling stroke of the pellets can be reduced to prevent the pellets from falling due to a long falling stroke and causing the pellets to be broken and damaged when falling.

[0045] When particles fall onto the top of the screening disc 604 and accumulate, the weight of the top of the screening disc 604 increases, and the burden of the spring 603 increases. When the positioning suction cup 605 and the bottom of the adsorption plate 606 are difficult to adsorb, the positioning suction cup 605 is separated from the adsorption plate 606, and the spring 603 recovers elastically, causing the screening disc 604 to swing up and down. When the screening disc 604 swings up and down, the particles accumulated on the screening disc 604 can be screened.

[0046] When the screening disc 604 is shaken up and down, the counterweight block 607 provided on the lower side of the screening disc 604 makes the side of the screening disc 604 close to the discharge chute 5 heavier. When the screening disc 604 is shaken, the side of the screening disc 604 close to the discharge chute 5 is tilted up and down for transportation. The screening disc 604 can be shaken obliquely to move the particles on the top of the screening disc 604 obliquely and make the particles fall into the discharge chute 5.

[0047] When the screening plate 604 drives the lifting cylinder 701 to shake up and down, the fixed frame 702 on the lifting cylinder 701 squeezes the telescopic connecting rod 703, so that the driven frame 704 on the other side of the telescopic connecting rod 703 is stressed, so that the driven frame 704 synchronously drives the moving frame 705, so that the rotating pulley 706 inside the moving frame 705 contacts the top of the damping pad 708 at the bottom of the moving fixed groove 707, so that the rotating pulley 706 slides on the top of the damping pad 708, so that the screening plate 604 can be easily moved. The force generated by the up and down shaking of the disc 604 when it is subjected to force is weakened by making the rotating pulley 706 slide on the top of the damping pad 708 in the movable fixed groove 707. The force of the lifting and lowering of the screening disc 604 is buffered by increasing the resistance of the rotating pulley 706 when it moves, so that the device can buffer the force when the screening disc 604 falls when in use, and avoid the screening disc 604 from shaking up and down too quickly to repeatedly hit the particles on the top of the screening disc 604, thereby avoiding damage to the particles.

[0048] For example 2, please refer to Figure 1-10 On the basis of the first embodiment, the present invention provides a technical solution: it also includes an injection assembly 8, and the injection assembly 8 is composed of a pressing plate 801, an air bag 802, a connecting pipe 803 and an injection head 804.

[0049] The pressure plate 801 is fixedly connected to the outer bottom of the lifting cylinder 701 and is staggered with the fixing frame 702. The airbag 802 is fixedly connected to the inner bottom of the fixing disc 602. The connecting pipe 803 is fixedly connected to the outer side of the airbag 802. The nozzle 804 is arranged on the inner wall of the driving box 3. The air in the airbag 802 can be sprayed out through the connecting pipe 803 and the nozzle 804.

[0050] The end of the connecting tube 803 away from the airbag 802 passes through the inner wall of the driving box 3 and extends to the outside of the driving box 3 and is fixedly connected to the nozzle 804. The nozzle 804 is embedded in the inner wall of the driving box 3, and the pressure plate 801 is arranged above the airbag 802. The air in the airbag 802 can be sprayed out through the connecting tube 803 and the nozzle 804.

[0051] When the screening disc 604 swings up and down, the pressure plate 801 on the lifting cylinder 701 squeezes the air bag 802, so that the air in the air bag 802 is ejected through the nozzle 804 on the connecting pipe 803. When the screening disc 604 swings up and down, the particles are impacted by the air ejected by the nozzle 804 in the air, which can clean the dust adhering to the surface of the particles and ensure the particle forming efficiency.
