Technical Field

[0001] The utility model belongs to the technical field of forage chopping, and in particular relates to a forage chopping device. Background Art

[0002] Forage grass is an herbaceous plant used to feed livestock, poultry or other herbivorous animals. In order to facilitate eating, promote digestion, evenly distribute and store conveniently, the forage grass needs to be chopped before feeding. Due to the long size of the forage grass, when it is processed by the existing chopping device, if some parts of the forage grass are parallel to the cutting direction of the cutting knife or at a small angle, the cut part of the forage grass will be longer. Since the chopped forage grass is mixed together, it is not convenient to sort out the longer forage grass for re-cutting, which will result in more forage segments in the processed forage residue, making it difficult for the forage grass to be fully digested in the digestive system of livestock, increasing the gastrointestinal burden, and may even cause indigestion, intestinal obstruction and other problems.

[0016] See also Figure 1-Figure 4The utility model provides the following technical solution: it includes an outer shell 1, a driving motor 13 and a fan 14, and is characterized in that: two cutting rollers 12 are arranged inside the outer shell 1, the fan 14 is located at the rear bottom of the outer shell 1, and a guide cutting assembly 2 is arranged at the front bottom of the outer shell 1, the guide cutting assembly 2 includes a guide sleeve 21, a mesh plate 1 22 and a mesh plate 2 23, the mesh plate 1 22 and the mesh plate 2 23 have the same size, the mesh plate 2 23 and the mesh plate 1 22 are both fixedly connected to the inner side of the guide sleeve 21, the mesh plate 1 22 and the mesh plate 2 23 are parallel to each other, and there is a gap between the mesh plate 23 and the mesh plate 1 22, a cutting knife 1 221 is arranged on the inner side of the mesh of the mesh plate 1 22, and a cutting knife 2 231 is arranged on the inner side of the mesh of the mesh plate 23, the cutting knife 1 221 and the cutting knife 2 231 are both in an inclined state, and the inclination directions of the cutting knife 1 221 and the cutting knife 2 231 are opposite.

[0017] In this embodiment, it includes an outer shell 1, a drive motor 13 and a fan 14. The interior of the outer shell 1 is a space for chopping grass. The drive motor 13 is a rotating motor, and the chopped grass can be blown out by the fan 14. Two cutting rollers 12 are arranged inside the outer shell 1. The two cutting rollers 12 can be rotated by the drive motor 13, and the rotation directions of the two cutting rollers 12 are opposite. When the grass enters between the two cutting rollers 12, the two cutting rollers 12 will chop the grass. The fan 14 is located at the rear bottom of the outer shell 1, and the cutting rollers 12 are located at the upper half of the outer shell 1. Therefore, the chopped grass will continue to fall downward, and then the wind force of the fan 14 can blow the grass out. The front bottom of the outer shell 1 is provided with a guide The guide cutting assembly 2 is opposite to the position of the fan 14, so the chopped grass will be discharged outward from the position of the guide cutting assembly 2. The guide cutting assembly 2 includes a guide sleeve 21, a mesh plate 1 22 and a mesh plate 23. The front and rear sides of the guide sleeve 21 are both in an open state, so the chopped grass can pass through the inner side of the guide sleeve 21. The mesh plate 1 22 and the mesh plate 2 23 have the same size. The meshes on the mesh plates 1 22 and 23 can allow grass to pass through, and at the same time, the grass can be filtered to a certain extent. Under the influence of wind, it is difficult for longer grass sections to pass through the mesh smoothly. The mesh plate 23 and the mesh plate 1 22 are both fixedly connected to the inner side of the guide sleeve 21. When the grass passes through the inside of the guide sleeve 21, it will be The grass passes through the meshes of the mesh plate 1 22 and the mesh plate 2 23, so that the grass can be double filtered, which is beneficial to improve the interception effect of the longer grass section. The mesh plate 1 22 and the mesh plate 2 23 are parallel to each other, and there is a gap between the mesh plate 23 and the mesh plate 1 22. A cutting knife 1 221 is provided on the inner side of the mesh of the mesh plate 1 22. Through the blowing of wind and the interception of the cutting knife 1 221, when the grass passes through the mesh of the mesh plate 1 22, the cutting knife 1 221 will cut the larger grass again. A cutting knife 231 is provided on the inner side of the mesh of the mesh plate 23. Similarly, through the blowing of wind on the grass and the interception of the cutting knife 231, when the grass passes through the mesh of the mesh plate 23, the cutting knife 2 231 will cut the larger grass again. The cutting is performed, and the cutting blade 1 221 and the cutting blade 2 231 are both in an inclined state, and the inclination directions of the cutting blade 1 221 and the cutting blade 2 231 are opposite. Since the inclination directions of the cutting blade 1 221 and the cutting blade 2 231 are opposite, it is helpful to reduce the situation where the grass segment is not directly discharged without contacting the cutting blade 1 221 or the cutting blade 2 231 due to the inclination direction of the grass segment being close to the cutting blade 1 221 or the cutting blade 2 231. Through two supplementary cuttings in different directions, it is helpful to reduce the number of grass segments with larger sizes, thereby improving the quality of the grass after chopped. When in use, the grass to be chopped needs to be put in from the top of the outer shell 1. When the grass passes between the two cutting rollers 12, the two cutting rollers 12 will cut the grass.The chopped grass will continue to fall to the position between the fan 14 and the discharge port 15. The wind force of the fan 14 will move the grass toward the discharge port 15. The grass will pass through the discharge port 15 and enter the inside of the guide sleeve 21. Inside the guide sleeve 21, the grass will pass through the mesh of the mesh plate 1 22 and the mesh plate 2 23 in turn, so that the plurality of cutting knives 1 221 and the cutting knives 2 231 will perform two die punching cuts on the larger grass segments, thereby reducing the content of larger grass in the cut grass.

[0018] A feed hopper 11 is provided at the top of the outer shell 1 , and a plurality of support frames 16 are provided at the bottom of the outer shell 1 ; grass can be fed into the inner part of the outer shell 1 through the feed hopper 11 , and the outer shell 1 can be supported through the plurality of support frames 16 .

[0019] The two cutting rollers 12 are opposite to each other, and the driving motor 13 is located at the rear side of the outer shell 1. The driving motor 13 corresponds to the position of the cutting rollers 12. The two cutting rollers 12 can be rotated by the driving motor 13, so as to achieve the purpose of cutting the grass.

[0020] A discharge port 15 is provided at the front bottom of the outer shell 1 , and the discharge port 15 corresponds to the position of the fan 14 ; when the grass falls to the position between the fan 14 and the discharge port 15 , the wind force of the fan 14 will move the grass toward the discharge port 15 .

[0021] The guide sleeve 21 is fixedly connected to the outer side of the outer shell 1 , and the inner side of the guide sleeve 21 is communicated with the discharge port 15 ; in the process of the forage grass being discharged outward, the forage grass will pass through the discharge port 15 and the inner side of the guide sleeve 21 in turn.

[0022] The working principle and use process of the utility model are as follows: when in use, firstly, the grass to be chopped needs to be put in from the top of the outer shell 1, and when the grass passes between the two cutting rollers 12, the two cutting rollers 12 will cut the grass, and the chopped grass will continue to fall to the position between the fan 14 and the discharge port 15, and the wind force of the fan 14 will make the grass move in the direction of the discharge port 15, and the grass will pass through the discharge port 15 into the inside of the guide sleeve 21, and inside the guide sleeve 21, the grass will pass through the mesh of the mesh plate 1 22 and the mesh plate 2 23 in turn, so that a plurality of cutting knives 1 221 and cutting knives 2 231 will perform two die punching cuts on the larger grass segments, thereby reducing the content of larger grass in the cut grass.
