Description
Technical Field
[0001] The utility model relates to the technical field of forage cutting, in particular to a forage cutting device for livestock breeding. Background Art
[0002] Forage grass is a plant that grows on grass and is usually used to feed livestock and poultry. They are widely planted and used, providing rich nutrition and energy, and play an important role in the development of animal husbandry. The length of forage grass should be adjusted according to different storage methods. If it is stored as hay, the length of forage grass is generally required to be around 5-10 cm. This is because a shorter length is conducive to the drying and ventilation of the forage grass and reduces the risk of mildew. For the storage of silage or forage grass, the length of the forage grass can be appropriately extended to 15-20 cm, so that more nutrients can be retained. Different livestock and poultry do have certain requirements for the length of forage grass. Different livestock and poultry species have different preferences and adaptability to the length of forage grass. The length of forage grass needs to be determined according to the oral structure and digestion capacity of livestock and poultry. Therefore, it is necessary to cut the forage grass to a fixed length.
[0003] In the related art, during the grass cutting process, the grass is generally cut by a cutting device with a rotating blade, and the grass is cut into sections, so as to store or feed the grass.

[0033] Reference Figure 1-Figure 4In a preferred embodiment, the fixed-length cutting mechanism includes a rotating shaft 41, which is movably connected to the inside of the cutting box 1, and the bottom of the surface of the rotating shaft 41 is fixedly connected to the chassis 42, and the surface of the rotating shaft 41 is movably connected to the cutting disk 43 located on the top of the chassis 42, and the staggered openings 44 are respectively opened on both sides of the chassis 42 and the cutting disk 43, and the staggered openings 44 on both sides of the cutting disk 43 are installed with cutting knives 45, and the motor 46 is fixedly connected to the bottom of the cutting box 1, and the bottom of the rotating shaft 41 is transmission-connected to the output end of the motor 46, and the lifting and length adjustment mechanism is arranged inside the rotating shaft 41. Since the chassis 42 and the cutting blade are movably connected to the inside of the cutting box 1 through the rotating shaft 41, and are fixedly connected to the cutting knife 45 inside the cutting disk 43 through the staggered openings 44, and the rotating shaft 41 is provided with a rotational force by the motor 46, before cutting the forage, the spacing distance between the cutting disk 43 and the bottom plate is adjusted and positioned according to the cutting length requirement of the forage. The cutting blade 45 is operated to make the height of the cutting blade 45 meet the cutting demand of the grass, and then the grass is added into the cutting box 1 through the feeding port 2. At this time, the motor 46 drives the chassis 42 and the cutting disc 43 to rotate through the rotating shaft 41, so that the cutting blade 45 cuts the entering grass to a fixed length within a certain length range. The lifting and length adjustment mechanism includes a lifting port 51, a lifting seat 52 and a length adjustment rod 53.

When the length adjusting rod 53 is used in conjunction with the cutting disk 43, a reference reference range for the length adjusting rod 53 to lift and move the cutting disk 43 can be provided, so as to avoid the situation that it is difficult to refer to the height when the cutting disk 43 is lifted and moved, thereby improving the convenience of lifting and adjusting the length of the length adjusting rod 53. A rotating cavity 7 is provided at the top of the lifting seat 52, and a rotating seat 8 is rotatably connected inside the rotating cavity 7. The top of the rotating seat 8 is fixedly connected to the bottom of the length adjusting rod 53.

At the same time, the grass entering the cutting box 1 is prevented from loosening, and the cut grass is discharged and guided to avoid the loosening of the grass after entering the cutting box 1, which makes it difficult for the cutting knife 45 to cut, thereby improving the stability of grass addition and cutting and the discharge effect.
[0037] Specifically, the working process or working principle of the forage cutting device for livestock breeding is as follows: when in use, first, according to the actual needs of forage cutting, the hand-held positioning frame 10 is moved to the left to disengage from the positioning slot 12, so that the length-adjusting rod 53 loses its positioning work. At this time, the spring 11 is affected by the moving force of the positioning frame 10 to the left and contracts. Then the hand-held length-adjusting rod 53 drives the cutting disc 43 and the cutting knife 45 to move up and down through the lifting seat 52. At this time, according to the number of reference blocks 6 located on the top of the cutting box 1, the height positions of the cutting disc 43 and the cutting knife 45 are referenced, so that the distance between the cutting knife 45 and the chassis 42 is within the range of the composite forage cutting length. At the same time, the material guide barrel 14 moves with the length-adjusting rod 53, so that the bottom of the material guide barrel 14 is always located at the top of the cutting disc 43, and then the positioning frame 10 is slowly released to allow the spring 11 to drag the positioning frame 10 into the positioning slot 12, and the lifting seat 52 after movement adjustment is adjusted. The rod and the cutting disc 43 are positioned, and then the motor 46 is connected to the external power supply through a wire, so that the motor 46 drives the chassis 42 and the cutting disc 43 to rotate through the rotating shaft 41, the lifting port 51 and the lifting seat 52, and then the hay bale to be cut is added to the cutting box 1 through the guide tube 14. At this time, the bottom of the hay bale added to the cutting box 1 contacts the top of the chassis 42 first. As the cutting disc 43 rotates, the cutting knife 45 contacts the hay bale located on the top of the chassis 42, and the hay bale is cut within a certain length range, so that the length of the cut hay can meet the use requirements. In this process, the rotating seat 8 rotates inside the rotating cavity 7 to perform rotational connection between the lifting seat 52 and the length adjusting rod 53. At the same time, the cleaning plate 13 scrapes and cleans the cut hay, so that the cut hay passes through the discharge port 3 into the discharge hopper 15 and is discharged from the cutting box 1.
[0038] It should be noted that the motor 46 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
