Description

Technical Field

[0001] This utility model relates to the field of straw cutting technology, and in particular to an agricultural straw cutting machine. Background Technology

[0002] Agricultural straw cutters are an important component of corn harvesters. They are mainly used to cut corn stalks for subsequent transportation, storage, and utilization, and are widely used in fields such as animal husbandry, feed processing, straw return to the field, and biomass energy.

[0003] Existing agricultural straw cutting machines have a relatively simple structure and poor adaptability to straw cutting. Due to different moisture contents, the straw cutting efficiency is low. Dry straw is brittle, and wet straw is prone to slipping during cutting, leading to blade wear. The feeding channel for cutting wet straw is prone to blockage, requiring frequent manual intervention, which is inconvenient to maintain and affects processing efficiency.

[0004] Therefore, in response to the problems of poor adaptability, low cutting efficiency, and easy clogging of existing agricultural straw cutting machines, an agricultural straw cutting machine can be designed. Utility Model Content

[0015] The beneficial effects of this utility model are:

[0016] 1. This agricultural straw harvesting and cutting machine utilizes long blades and crushing rollers. The controller operates a cutting cylinder to drive the cutter to perform a preliminary cut on the moving straw. The cutting length can be flexibly adjusted to reduce the load of a single cut and minimize wear on the blades. After the preliminary cut, the straw falls into the cutting box. The rotating cutting rollers drive the long blades to rotate, and together with the fixed long blades, they perform a secondary fine cut, further cutting the straw into finer and more uniform pieces to meet the requirements of different applications for straw fineness. Two crushing rollers rotate in opposite directions to evenly crush the straw into fine particles. This three-stage cutting improves the overall straw processing efficiency, meets diverse market demands, and increases production efficiency.

[0017] 2. This agricultural straw harvesting and cutting machine uses a perforated plate and extrusion rollers. The harvested corn stalks move with the conveyor belt, and the extrusion rollers move up and down to press the stalks, adapting to stalks with different moisture contents and playing a fixing role to prevent the stalks from moving during cutting. The finely cut stalks fall into the crushing box through the perforated plate. The vibration of the perforated plate facilitates rapid screening, effectively preventing blockage and contributing to the continuity of the cutting operation. Attached Figure Description

Squeezing rollers 13 are provided on both the front and rear sides of the cutter 12. In use, the harvested corn stalks are cut with... The conveyor belt 8 moves, and the extrusion roller 13 moves up and down to press the straw, adapting to straw with different moisture contents and playing a fixing role to prevent the straw from moving during cutting. The controller 9 controls the cutting cylinder 11 to drive the cutter 12 to perform initial cutting on the moving straw. The cutting length can be flexibly adjusted to reduce the load of a single cut and reduce wear on the blade. After initial cutting, the straw falls into the cutting box 1. The cutting roller 2 rotates, driving the long blade 3 to rotate, and together with the fixed long blade 3, it performs a second fine cut to further cut the straw into finer and more uniform pieces to meet the requirements of different uses for straw fineness. The finely cut straw falls into the crushing box 5 through the perforated plate 4. The perforated plate 4 vibrates to facilitate rapid screening, effectively prevents blockage, and helps the continuity of the cutting operation. The two crushing rollers 6 rotate relative to each other to evenly crush the straw into fine particles. The three-stage cutting improves the overall straw processing efficiency, meets diversified market demands, and improves production efficiency.

[0026] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, six long blades 3 are arranged in a circular array. A feed inlet 14 is provided at the rear end of the cutting box 1. The upper end of the feed inlet 14 is fixedly connected to the same long blades 3. The straw after initial cutting falls into the cutting box 1 from the feed inlet 14. The multiple long blades 3 cooperate with the fixed long blades 3 to perform secondary fine cutting, thereby improving cutting efficiency. A cutting motor 15 is fixedly connected to the left end of the cutting box 1. The output shaft of the cutting motor 15 is fixedly connected to the cutting roller 2. The cutting motor 15 is electrically connected to the controller 9. The cutting motor 15 drives the cutting roller 2. Roller 2 rotates, and fixed plates 16 are fixedly connected to both the front and rear ends of the inner wall of the cutting box 1. Springs 17 are connected to the left and right sides of the upper end of the fixed plate 16. The end of the spring 17 away from the fixed plate 16 is fixedly connected to the lower end of the perforated plate 4. The spring 17 drives the perforated plate 4 to vibrate, and the vibration is uniform. A vibration motor 18 is fixedly connected to the upper end of the front fixed plate 16.

The output shaft of the crushing motor 19 is fixedly connected to the crushing roller 6. The crushing motor 19 is electrically connected to the controller 9. The crushing motor 19 drives the two crushing rollers 6 to rotate relative to each other. Circular blades 20 are fixedly connected to the outer side of the crushing roller 6. There are seven circular blades 20 evenly distributed, and the circular blades 20 on the two crushing rollers 6 are staggered. The crushing roller 6 drives the circular blades 20 to rotate relative to each other, which improves the crushing efficiency. Two lifting cylinders 21 are fixedly connected to the upper end of the support plate 7. A connecting frame 22 is fixedly connected to the output end of the lifting cylinder 21. The two ends of the extrusion roller 13 are rotatably connected to the connecting frame 22. The lifting cylinder 21 is electrically connected to the controller 9. The lifting cylinder 21 simultaneously drives the extrusion roller 13 to move up and down to press and compact the straw, adapting to straw with different moisture contents and playing a fixing role.

[0028] During operation, the harvested corn stalks move along the conveyor belt 8. Simultaneously, the lifting cylinder 21 drives the pressing roller 13 to move up and down, pressing the stalks to accommodate different moisture contents and providing a fixing function. The controller 9 operates the cutting cylinder 11 to drive the cutter 12 to perform a preliminary cut on the moving stalks. The cutting length can be flexibly adjusted. After the preliminary cut, the stalks fall from the feed inlet 14 into the cutting box 1. The cutting motor 15 drives the cutting roller 2 to rotate, which in turn drives the long blade 3 to rotate, performing a secondary fine cut in conjunction with the fixed long blade 3. This further cuts the stalks into finer and more uniform pieces, meeting the fineness requirements of different applications. The vibration motor 18 drives the perforated plate 4 to vibrate, and the finely cut stalks fall through the perforated plate 4 into the crushing box 5. The crushing motor 19 drives two crushing rollers 6 to rotate relative to each other, driving the circular blade 20 to evenly crush the stalks into fine particles. This three-stage cutting improves the overall processing efficiency of the stalks, meets diverse market demands, and increases production efficiency.
