Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a straw fiber length grading control cutting machine. Background Technology

[0002] Straw is a general term for the stems and leaves of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops after the grains are harvested. More than half of the products of crop photosynthesis are found in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a renewable biological resource with multiple uses. Straw is also a roughage, characterized by its high crude fiber content and lignin. Although lignin cellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant animals such as cattle and sheep.

[0003] Cutters are often used to cut straw during processing. However, the shredded straw produced by existing cutters is usually random. The feeding speed directly affects the size and length of the shredded straw, making it difficult to control the cutting length precisely and making it very inconvenient to use.

[0004] To address the aforementioned issues, this application proposes a straw fiber length grading and control cutting machine. Utility Model Content

[0025] Please see Figure 1-7 The technical solution provided by this utility model specifically includes the following embodiments:

[0026] A straw fiber length grading and control cutting machine, including an operating table 1;

[0027] Feeding mechanism 2: The top of the operating table 1 is equipped with a feeding mechanism 2, which is used to feed straw.

[0028] The cutting mechanism 3 is installed on the top of the operating table 1. The cutting mechanism 3 is located in front of the feeding mechanism 2 and extends to the bottom of the operating table 1. The cutting mechanism 3 is used to cut straw materials.

[0029] The length-limiting mechanism 4 is installed on the front side of the operating table 1. The length-limiting mechanism 4 is used to limit the extension length of the straw.

[0030] The feeding mechanism 2 includes a roller 21, which is movably connected to the top of the operating table 1 via a bearing seat. An annular cylinder 22 is sleeved on the outer end of the roller 21. A fixing plate 24 is fixedly connected to one side of the operating table 1. A motor 23 is fixedly connected to the top of the fixing plate 24. The output shaft of the motor 23 is fixedly connected to one end of the roller 21.

[0031] The outer surface of the annular cylinder 22 is processed with anti-slip particles, and the outer wall of the roller 21 is provided with an annular groove for the annular cylinder 22 to be embedded. There is a certain friction between the roller 21 and the annular cylinder 22. When conveying straw, the roller 21 can rotate the annular cylinder 22 together with the annular cylinder through friction, so that the annular cylinder 22 contacts the straw and conveys it. When the front end of the straw is blocked by the limiting plate in the length-fixing mechanism 4 and cannot be conveyed forward, a large friction will be generated between the straw and the outer surface of the annular cylinder 22. This friction will be greater than the friction between the roller 21 and the annular cylinder 22. Therefore, the annular cylinder 22 will remain stationary, but the roller 21 will continue to rotate without being affected until the straw can continue to move forward. At this time, the resistance on the outer surface of the annular cylinder 22 disappears or decreases. Then, the annular cylinder 22 can continue to rotate with the roller 21 through the friction between them to convey the straw.

[0032] The feeding mechanism 2 also includes a protective cover 25, which is fixedly connected to the top of the operating table 1, and the roller 21 is located inside the protective cover 25. The protective cover 25 covers the roller 21 inside, which can prevent the roller 21 from being accidentally hit during operation and causing an accident.

[0033] The cutting mechanism 3 includes a crossbeam 31 located above the operating table 1. A cutting blade 32 is bolted to the bottom front side of the crossbeam 31. Piston rods 33 are fixedly connected to both ends of the crossbeam 31. The piston rods 33 pass through the operating table 1 and are slidably connected to the operating table 1. A connecting arm 34 is fixedly connected to the bottom of both piston rods 33. A crankshaft 36 is connected below the connecting arm 34 and is movably connected to the support leg of the operating table 1. A connecting rod 35 is movably connected between the connecting arm 34 and the crankshaft 36. A second motor 37 is fixedly connected to the outside of the support leg of the operating table 1. The output shaft of the second motor 37 is fixedly connected to one end of the crankshaft 36.

[0034] The cutting mechanism 3 is driven by motor 37, and then by crankshaft 36, connecting rod 35, connecting arm 34, piston rod 33 and crossbeam 31, so that the cutting blade 32 can move up and down to cut the straw.

[0035] The fixed length mechanism 4 includes a mounting plate 41, which is fixedly connected to the front side of the operating table 1. A threaded rod 42 is connected through the front side of the mounting plate 41. The mounting plate 41 and the threaded rod 42 are threadedly connected. A limit plate 43 is movably connected to the rear side of the threaded rod 42. A rotating wheel 44 is fixedly connected to the front side of the threaded rod 42.

[0036] Rotating the threaded rod 42 via the rotating wheel 44 can drive the limiting plate 43 to move back and forth. When the limiting plate 43 moves backward, that is, closer to the cutting blade 32, the length of the straw particles cut off each time is shorter. Conversely, when the limiting plate 43 moves forward and away from the cutting blade 32, the length of the straw particles cut off is longer.

[0037] A guide bar 45 is fixedly connected to the inner wall of the operating table 1. The limiting plate 43 is slidably connected to the inside of the operating table 1 through the guide bar 45. A scale line 46 is machined on the inner wall of the operating table 1, and the scale line 46 is located above the guide bar 45.

[0038] When the limiting plate 43 moves back and forth, the guide bar 45 can guide and limit the limiting plate 43, so that it can move stably without rotation or tilting. The scale line 46 can help determine the adjustment position of the limiting plate 43.

[0039] In the above scheme, when the feeding mechanism 2 and the cutting mechanism 3 are running, the speed of the feeding mechanism 2 when conveying straw forward is always greater than the speed of the cutting blade 32 in the cutting mechanism 3 when it falls. Therefore, when the cutting blade 32 falls to cut the straw, the straw is always in a state of being positioned and waiting to be cut.

[0040] Working principle:

[0041] In use, the straw is placed on the operating table 1 and guided to the cutting mechanism 3 by the feeding mechanism 2. The cutting mechanism 3 then cuts the straw. Before cutting, the length-limiting mechanism 4 is adjusted to limit the length of the straw extending from below the cutting blade 32 in the cutting mechanism 3. Specifically, this is achieved by rotating the threaded rod 42 via the rotating wheel 44. The threaded rod 42 then moves forward or backward along with the limiting plate 43. The specific distance can be determined by referring to the scale line 46. Subsequently, when the roller 21 in the feeding mechanism 2 rotates to push the straw forward, the front end of the straw, after extending a certain length from below the cutting blade 32, is blocked by the limiting plate 43 and cannot move further. Since the roller 21 contacts the straw through the annular cylinder 22, when the straw cannot move forward, this... When the annular cylinder 22 stops rotating due to excessive friction on its outer surface, sliding friction will occur between the roller 21 and the annular cylinder 22, meaning the roller 21 will continue to rotate. After the straw completes one cutting operation, the front end of the straw can move forward again without restriction. At this time, the sliding friction on the outer surface of the annular cylinder 22 decreases, so the annular cylinder 22 can rotate together with the roller 21 to transport the straw. When the cutting blade 32 is cutting, it is mainly driven by the motor 37 to rotate the crankshaft 36, and then the two piston rods 33 slide up and down through the transmission of the connecting rod 35 and the connecting arm 34, which in turn moves the crossbeam 31 and the cutting blade 32 up and down. Each time the cutting blade 32 falls, it will cut the straw once.
