[0002] Corn stalks are rich in nutrients and available chemical components and can be used as raw materials for livestock feed. For a long time, corn stalks have been one of the main roughage raw materials for livestock. In the process of cutting corn stalks, a stalk cutter is needed to cut the corn stalks.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved: during long-term use of the pole cutting machine, the blade edge is easy to become blunt, which affects the cutting accuracy of the corn stalks, and the staff needs to disassemble the blade for grinding, but the existing pole cutting machine tool is placed on the inside of the pole cutting machine, and the internal space of the pole cutting machine is small, which is not convenient for the staff to disassemble.

[0004] Therefore we propose a rod cutting machine tool assembly that can solve the above problems. Utility Model Content

[0007] As an optional solution of the technical solution of the present application, a spring is provided on a side of the second adjusting block away from the first adjusting block, and the spring is sleeved on the outer side of the fixing pin.

[0008] As an optional solution of the technical solution of the present application, a knob is fixedly mounted on one end of the threaded rod placed on the outside of the knife rod, and anti-slip grooves are provided on the outside of the knob.

[0009] As an optional solution of the technical solution of the present application, three groups of mounting holes are evenly opened on the upper surface of the turntable, and the upper end of the knife rod passes through the mounting groove and is welded to the turntable.

[0010] As an optional solution of the technical solution of the present application, the two ends of the spring are fixedly connected to the inner wall of the connecting groove and the outer side of the second adjustment block respectively, and the fixing pin matches the size of the connecting groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the threaded rod can be rotated by the knob, and during the rotation of the threaded rod, the first adjusting block can be driven to move up and down in the connecting groove; when the first adjusting block moves downward, the two groups of second adjusting blocks can be pushed to move in the opposite direction, thereby pushing one end of the fixing pin to pass through the fixing hole on the outside of the connecting sleeve, thereby limiting and fixing the connecting sleeve, facilitating the fixed connection between the knife rod and the blade; by rotating the knob in the opposite direction, the threaded rod drives the first adjusting block to move upward, and the elastic force of the spring can push the two groups of second adjusting blocks to move relative to each other, further pulling the fixing pin out of the fixing hole and releasing the lock on the connecting sleeve, thereby quickly disassembling the blade without disassembling the knife rod.

[0017] In this technical solution, the connecting sleeve 14 is placed on the outside of the knife rod 1 so that the fixing hole 15 on the outside of the connecting sleeve 14 is aligned with the guide groove 17 on the outside of the knife rod 1. The threaded rod 22 can be rotated by the knob 23, and the threaded rod 22 is threadedly connected to the first adjusting block 2. During the rotation of the threaded rod 22, the first adjusting block 2 can be driven to move up and down in the connecting groove 16. When the first adjusting block 2 moves downward, it can push the two groups of second adjusting blocks 21 to move in the opposite direction, thereby pushing one end of the fixing pin 18 to pass through the fixing hole 15 on the outside of the connecting sleeve 14, thereby limiting and fixing the connecting sleeve 14, and facilitating the fixed connection between the knife rod 1 and the blade 11.

[0018] In this embodiment, a spring 24 is provided on the side of the second adjustment block 21 away from the first adjustment block 2. The spring 24 is sleeved on the outside of the fixing pin 18, and the two ends of the spring 24 are fixedly connected to the inner wall of the connecting groove 16 and the outside of the second adjustment block 21 respectively.

[0019] In this technical solution, by rotating the knob 23 in the opposite direction, the threaded rod 22 drives the first adjustment block 2 to move upward, and the elastic force of the spring 24 can push the two groups of second adjustment blocks 21 to move relative to each other, further pulling the fixing pin 18 out of the fixing hole 15 and releasing the lock on the connecting sleeve 14, so that the blade 11 can be quickly disassembled without disassembling the knife rod 1.

[0021] In this technical solution, the upper end of the knife rod 1 is passed through the mounting groove 13, and then the position of the blade 11 on the outer side of the knife rod 1 is adjusted before welding, so that the knife rod 1 is fixedly connected to the turntable 12. Further, when the motor drives the turntable 12 to rotate, the blade 11 on the outer side of the knife rod 1 can be driven to rotate, thereby effectively cutting the corn stalks.

[0022] When a bar cutting machine tool assembly is used, the connecting sleeve 14 is placed on the outside of the knife bar 1, so that the fixing hole 15 on the outside of the connecting sleeve 14 is aligned with the guide groove 17 on the outside of the knife bar 1, and the threaded rod 22 can be rotated by the knob 23, and the threaded rod 22 is threadedly connected with the first adjusting block 2. During the rotation of the threaded rod 22, the first adjusting block 2 can be driven to move up and down in the connecting groove 16. When the first adjusting block 2 moves downward, the two groups of second adjusting blocks 21 can be pushed to move in the opposite direction, thereby pushing one end of the fixing pin 18 to pass through the fixing hole 15 on the outside of the connecting sleeve 14, further limiting and fixing the connecting sleeve 14, facilitating the fixed connection between the knife bar 1 and the blade 11, and adjusting the upper end of the knife bar 1 The end passes through the mounting groove 13, and then the position of the blade 11 on the outer side of the knife rod 1 is adjusted and then welding is performed to fix the knife rod 1 and the turntable 12. Further, when the motor drives the turntable 12 to rotate, the blade 11 on the outer side of the knife rod 1 can be driven to rotate, thereby effectively cutting the corn stalks. When the blade 11 needs to be maintained, the knob 23 is rotated in the opposite direction, and the threaded rod 22 drives the first adjusting block 2 to move upward. The elastic force of the spring 24 can push the two groups of second adjusting blocks 21 to move relative to each other, and further pull the fixing pin 18 out of the fixing hole 15 and release the lock on the connecting sleeve 14, so that the blade 11 can be quickly disassembled without disassembling the knife rod 1.
