Description

Technical Field

[0001] The utility model belongs to the technical field of dairy cow breeding, in particular to a hay cutting device for dairy cow breeding. Background Art

[0002] Hay is feed for dairy cows. During the process of raising dairy cows, a cutting device is needed to cut the hay. When the existing cutting device cuts the hay, it is very easy for the hay to adhere to the surface of the cutting knife, which is inconvenient to clean. The hay debris adheres to the surface of the cutting knife for a long time, which will cause the cutting knife to be damaged due to rust.

[0003] Example (authorization announcement number CN112790021B) A hay cutting device for dairy cattle breeding, comprising a bottom plate, a bracket fixedly connected to the top of the bottom plate, a rotating shaft movably connected to the front of the bracket, a roller fixedly connected to the outer wall of the rotating shaft, a conveyor belt sleeved on the outer wall of the roller, and a power output mechanism fixedly installed on the top of the bottom plate, the power output mechanism comprising a motor seat. The hay cutting device for dairy cattle breeding can drive the conveyor belt to drive the hay through the transmission of the motor, and can also drive the cutting mechanism to work through the setting of the transmission gear and the driven gear. Compared with people using the gate knife to cut hay, a lot of manpower and material resources are saved, and at the same time, the efficiency of hay cutting is greatly improved, and the need for two people to work together to cut hay is avoided, which brings great convenience to people's hay cutting work. However, the device does not consider cleaning the hay residues adhered to the surface of the cutting knife. The hay residues adhere to the surface of the cutting knife for a long time, which is very easy to cause the cutting knife to be damaged due to rust. Utility Model Content

[0027] The inner wall of the telescopic outer rod 9 is slidably connected with a movable block 8 and a moving block 11. Both the movable block 8 and the moving block 11 are square, which facilitates the relative rotation of the movable block 8 and the moving block 11 when they move in the inner cavity of the telescopic outer rod 9, thereby improving the structural stability of the device parts. The end face of the telescopic outer rod 9 is embedded with a threaded sleeve 14, which is located on the side of the telescopic outer rod 9 away from the fixed frame 4. The threaded sleeve 14 is threadedly connected with a threaded rod 13, so that the threaded rod 13 moves along the threaded path of the threaded sleeve 14. The side of the threaded rod 13 is interference-fitted with a limit bearing 12, and the limit bearing 12 is set to fix the rotation position of the threaded rod 13.

The movable plate 18 provides support and fixing for the cutting knife 2, which is convenient for the moving end of the electric telescopic rod 17 to move downward, and the cutting knife 2 is moved downward during the transmission process to cut the hay placed on the top surface of the cutting table 1. A material guide component 19 is provided on the inner top wall of the cutting table 1, and the material guide component 19 includes a connecting plate 20 and a mounting plate 26.

[0030] The top surfaces of the connecting plate 20 and the mounting plate 26 are welded to the inner top wall of the cutting table 1 to fix the positions of the connecting plate 20 and the mounting plate 26.

The working principle, size and model are irrelevant to the function of the present application, so no further description is given. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] How it works

[0033] When using the hay cutting device for dairy cattle breeding, the user places the hay to be cut at a specified position on the top surface of the cutting table 1, starts the electric telescopic rod 17, and under the connection action of the movable plate 18, the moving end of the electric telescopic rod 17 moves downward, and the cutting knife 2 moves downward during the transmission process to achieve the cutting effect on the hay. At the same time, the electric push rod 25 is started, and the moving end of the electric push rod 25 moves. Under the connection action of the connecting rod 24, the limit rod 23 is relatively rotated and moved along the inner wall of the limit frame 22. The bottom surface of the connecting plate 20 is rotatably connected to the guide plate 21 through a pin shaft. During the transmission process, it is convenient to control the rotation angle of the guide plate 21, which is suitable for the guide demand of hay and improves the convenience of use of the device. The provided mounting plate 26 fixes the position of the electric push rod 25 to improve the structural stability of the device parts.

[0034] The two sides of the fixed frame 4 are fixedly connected with telescopic outer rods 9. Under the elastic thrust of the boosting spring 10, the movable block 8 moves along the inner cavity of the telescopic outer rod 9. Under the connection between the telescopic inner rod 7 and the movable plate 5, the adjacent sides of the two scrapers 6 are in contact with the cutting knife 2, so that the hay debris adhered to the surface of the cutting knife 2 is cleaned to prevent the surface of the cutting knife 2 from rusting and damage. The rotating block 15 rotates to make the threaded rod 13 move down along the threaded path of the threaded sleeve 14. The distance between the movable block 8 and the movable block 11 is shortened during the transmission process, and the elastic thrust of the boosting spring 10 is strengthened. The adjacent sides of the two scrapers 6 are prevented from being loosely in contact with the cutting knife 2 during the transmission process, reducing the cleaning effect of the hay debris adhered to its surface, thereby preventing the cutting knife 2 from being rusted and damaged.
