[0002] The silage machine is mainly used to process fresh grass to make high-humidity silage, which is one of the most important feeds in animal husbandry and is of great significance to the development of animal husbandry. It can efficiently harvest corn stalks, sorghum stalks, forage grass, etc., and chop and compact them to make silage. This feed is widely used in animal husbandry and provides a nutritious and easy-to-digest feed source for cattle, sheep and other livestock. The serrated cutter is an important part of the silage machine in the harvesting process;

[0003] During the installation process of the existing serrated cutting knife, since the existing serrated cutting knife is usually installed on the silage machine in a fixed connection mode, it is difficult to quickly adjust according to the material characteristics and cutting requirements when facing different material characteristics and cutting requirements. This fixity not only causes the serrated cutting knife to be unable to adjust the height according to different materials when cutting different materials, and cannot achieve the best cutting effect, thereby affecting the cutting quality and efficiency, but also if the height of the serrated cutting knife is not set properly, it will cause excessive friction and resistance during the cutting process, thereby increasing energy consumption and wear of the cutting knife, and reducing the service life of the silage machine.

[0004] Therefore, we proposed a serrated cutting knife for silage machine to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-4 As shown, a serrated cutting knife for a silage machine includes a mounting frame 1, the upper and lower end surfaces of the mounting frame 1 are symmetrically fixedly connected with a mounting plate 2, one side of the mounting frame 1 is vertically slidably connected with a lifting plate 3, the lifting plate 3 is fixedly connected with a cutting knife body 4 on the side away from the mounting frame 1, the lifting plate 3 is threadedly connected with a threaded rod 7, and the threaded rod 7 is rotatably connected to the mounting frame 1.

[0025] In this embodiment, Figure 3 As shown, vertical grooves 18 are symmetrically provided on the upper end of the outer surface of the threaded rod 7, and lifting blocks 19 are vertically slidably connected in the vertical grooves 18. Knobs 8 are fixedly connected between the lifting blocks 19. The knobs 8 are sleeved on the upper end of the threaded rod 7. The lifting blocks 19 and the vertical grooves 18 are slidably connected, so that the knobs 8 can be driven to slide up and down on the upper end of the threaded rod 7.

[0026] In this embodiment, Figure 2 and Figure 3 As shown, the upper end surface of the mounting frame 1 is symmetrically provided with slide grooves 9, and sliders 10 are slidably connected in the slide grooves 9. The upper end surfaces of the sliders 10 are rotatably connected with linkage plates 16, and a ring 17 is rotatably connected between the ends of the linkage plates 16 away from the sliders 10. The ring 17 is sleeved on the outer surface of the knob 8, and an annular groove 20 is provided on the outer surface of the knob 8. The ring 17 is slidably connected in the annular groove 20. When the knob 8 moves up and down, the slider 10 can be driven to slide synchronously in the slide groove 9 through the provided ring 17 and linkage plate 16.

[0027] In this embodiment, Figure 2 As shown, a clamping column 15 is fixedly connected to one side of each slider 10, a disc 13 is arranged between the clamping columns 15, the disc 13 is fixedly connected to the outer surface of the threaded rod 7, and clamping holes 14 are equidistantly arranged in an annular shape on the outer surface of the disc 13. The clamping columns 15 are clamped with the clamping holes 14, and the threaded rod 7 can be fixed by clamping the clamping columns 15 into the clamping holes 14 on the outer surface of the disc 13, so as to prevent the threaded rod 7 from rotating due to external factors.

[0028] In this embodiment, Figure 4 As shown, connecting columns 11 are fixedly connected to the opposite sides of the sliders 10, and the connecting columns 11 are all slidably connected to the mounting frame 1. Springs 12 are sleeved on the outer surfaces of the connecting columns 11, and one end of the spring 12 is fixedly connected to the side wall of the slider 10, and the other end of the spring 12 is fixedly connected to the inner wall of the slide groove 9. When the slider 10 moves in the slide groove 9, it can push the connecting column 11 to slide synchronously on the mounting frame 1 and squeeze the spring 12.

[0029] In this embodiment, Figure 4 As shown, the connecting column 11 is fixedly connected to the connecting plate 6 at one end away from the slider 10, and the connecting plate 6 is fixedly connected to the side close to the cutting knife body 4 with a clamping plate 5. The clamping plate 5 is evenly spaced with scale grooves 21 on the side close to the cutting knife body 4. When the clamping plate 5 is clamped on both sides of the cutting knife body 4, the cutting knife body 4 can be inserted into the scale groove 21.

[0030] The effects achieved by this embodiment are as follows: In the prior art, the position of the sawtooth cutting knife is difficult to be quickly adjusted according to the material characteristics and cutting requirements. This fixity not only causes the sawtooth cutting knife to be unable to adjust its height for different materials when cutting different materials, and cannot achieve the best cutting effect, thereby affecting the cutting quality and efficiency. Moreover, if the height of the sawtooth cutting knife is improperly set, it will cause excessive friction and resistance in the cutting process, thereby increasing energy consumption and wear of the cutting knife, and reducing the service life of the silage machine. Compared with the prior art, the position of the cutting knife body 4 on the mounting frame 1 can be adjusted and fixed according to the characteristics of different materials, so as to change the cutting height of the cutting knife body 4 on the material, which can not only ensure that the cutting knife body 4 contacts the material at the best angle and position, reduce the resistance in the cutting process, and improve the cutting efficiency, thereby speeding up the working speed of the silage machine and improving the production efficiency, but also the reasonable cutting height setting can reduce the friction and impact between the cutting knife body 4 and the material, reduce the wear rate of the cutting knife body 4, reduce the frequency of replacing the cutting knife body 4, and extend the service life of the silage machine;

[0031] By setting the clamping plate 5 and the scale groove 21, not only can the cutting knife body 4 be further stabilized after the height adjustment of the cutting knife body 4 is completed, reducing the cutting error caused by vibration or shaking during the cutting process, and ensuring the accuracy and consistency of the cutting, but it also makes it convenient for the staff to accurately understand the adjustment height of the cutting knife body 4, so that the staff can set and adjust to the appropriate cutting height more quickly, thereby reducing the time for repeated adjustments and improving the overall work efficiency.

[0032] The working process and principle involved in the overall content of the above embodiment are as follows:

[0033] When the staff installs the cutting knife body 4 on the silage machine, the cutting knife body 4 can be installed through the mounting frame 1 and the mounting plate 2. After the cutting knife body 4 is installed, according to the type of materials that the silage machine and the cutting knife body 4 need to harvest, the staff can first press down the knob 8, and the lifting block 19 and the vertical groove 18 are slidably connected, so that the knob 8 can slide downward on the outer surface of the threaded rod 7. As the knob 8 descends, the ring 17 set on the outer surface can be driven to descend synchronously, so that the ring 17 can rotate and connect the two sides of the link The upper end of the movable plate 16 is pressed downward, driving the linkage plate 16 to move from the inclined state to the horizontal state. During the state change of the linkage plate 16, the linkage plate 16 can push the slider 10 to slide horizontally in the slide groove 9 away from the threaded rod 7, driving the slider 10 to slide out of the clamping column 15 connected to the side of the threaded rod 7 close to the slider 10, and the clamping column 15 is opened on the outer surface of the disc 13. The slider 10 squeezes the spring 12 in the slide groove 9. During the movement of the slider 10 in the direction of the spring 12, the connecting column 11 can be pushed to slide out of the mounting bracket 1 synchronously, and pass through The connecting column 11 is away from the connecting plate 6 connected to one side of the slider 10, driving the clamping plates 5 on both sides away from the cutting knife body 4. After the clamping column 15 completely slides out of the clamping hole 14 and the clamping plate 5 and the cutting knife body 4 are separated, the staff can rotate the knob 8 horizontally, and the horizontal limit of the lifting block 19 by the vertical groove 18 can drive the threaded rod 7 to rotate synchronously on the mounting frame 1. At this time, the ring 17 will slide in the annular groove 20 opened on the outer surface of the knob 8. Since the threaded rod 7 and the lifting plate 3 are threadedly connected, when the threaded rod 7 rotates, the lifting plate 3 can be driven to slide up and down in the mounting frame 1, thereby changing the height of the cutting knife body 4 connected to the side wall of the lifting plate 3, which can not only ensure that the cutting knife body 4 contacts the material at the best angle and position, reduce the resistance in the cutting process, and improve the cutting efficiency, thereby speeding up the working speed of the silage machine and improving the production efficiency, but also the reasonable cutting height setting can reduce the friction and impact between the cutting knife body 4 and the material, reduce the wear rate of the cutting knife body 4, reduce the frequency of replacing the cutting knife body 4, and extend the service life of the silage machine;

[0034] When the staff has completed the height adjustment of the cutting knife body 4, the staff can loosen the knob 8. At this time, through the rebound force of the spring 12 connected between the slider 10 and the slide groove 9, the slider 10 can be pushed to automatically slide in the slide groove 9 in the direction of the threaded rod 7, pushing the clamping column 15 to be clamped into the clamping hole 14 opened on the outer surface of the disc 13 again, and the slider 10 will pull the clamping plate 5 to fit the two sides of the cutting knife body 4 again through the connecting column 11 and the connecting plate 6, so that the cutting knife body 4 is clamped into the scale groove 21 opened on the two clamping plates 5. Not only can the cutting knife body 4 be further stabilized after the height adjustment is completed, reducing the cutting error caused by vibration or shaking during the cutting process, ensuring the accuracy and consistency of cutting, but also it is convenient for the staff to accurately understand the adjustment height of the cutting knife body 4, so that the staff can set and adjust to the appropriate cutting height more quickly, thereby reducing the time for repeated adjustment and improving the overall work efficiency.
