DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] See also Figures 1 to 4 A hay cutter for dairy cattle breeding in this embodiment includes a barrel for feeding hay bales and a cutting structure arranged on the barrel. The barrel is provided with a feeding device and a discharge structure for feeding and discharging the cut hay.

[0024] In this embodiment, the barrel includes a bottom barrel 2 fixedly mounted on a base 1 and a cylinder 3 rotatably connected to the bottom barrel 2. The cylinder 3 is a cylindrical structure with upper and lower openings. One end of the cylinder 3 is rotatably connected to the bottom barrel 2 so as to be rotatably mounted on the base 1.

[0025] It should be noted that a rotating device for pulling the cylinder 3 to rotate should be provided on the base 1. Specifically, a rack for driving the cylinder 3 is fixedly installed on the outer wall of the cylinder 3. The rotating device uses a gear that meshes with the rack outside the cylinder 3, so that the cylinder 3 is pulled to rotate relative to the bottom cylinder 2.

[0026] Preferably, the inner wall of the cylinder 3 is fixedly mounted with oblique teeth 7 for pulling hay, and the oblique teeth 7 include a plurality of oblique teeth 7 arranged at equal distances on the inner wall of the cylinder 3 .

[0027] The cutting structure in this embodiment includes a first turntable 8 and a second turntable 9 rotatably mounted on the inner wall of the bottom cylinder 2 and a driving member for pulling the first turntable 8 and the second turntable 9 to rotate. Cutting teeth 10 located inside the cylinder 3 are fixedly mounted on the surface of the first turntable 8 and the second turntable 9. The hay put into the cylinder 3 can be cut by rotating the first turntable 8 and the second turntable 9.

[0028] In this embodiment, the driving member includes a motor 15 fixedly mounted on the outside of the bottom cylinder 2, a traction shaft 21 fixedly connected to the power end of the motor 15, a first gear 22 fixedly mounted on the outside of the traction shaft 21, and a main shaft 14 rotatably mounted on the inner wall of the bottom cylinder 2, and the main shaft 14 is fixedly connected to the center of the second rotating disk 9;

[0029] A first meshing wheel 16 is fixedly mounted on the outside of the main shaft 14 . An auxiliary shaft 24 is rotatably mounted on the bottom cylinder 2 . An auxiliary wheel 25 meshing with the first gear 22 is fixedly mounted on the auxiliary shaft 24 . The first meshing wheel 16 meshes with the auxiliary wheel 25 .

[0030] By providing the auxiliary shaft 24 and the auxiliary wheel 25 , the traction rod 21 can drive the first meshing wheel 16 to rotate.

[0031] In a specific implementation, the traction shaft 21 is driven to rotate by the motor 15. The traction shaft 21 drives the externally fixed first gear 22 to rotate while rotating. When the first gear 22 is engaged with the first meshing wheel 16, it can drive the main shaft 14 connected to the first meshing wheel 16 to rotate, that is, pull the second turntable 9 to rotate.

[0032] It should be noted that a rotating sleeve 18 is rotatably mounted on the outside of the main shaft 14, and a second meshing gear 19 is fixedly mounted on one end of the rotating sleeve 18. One end of the rotating sleeve 18 is connected to a bracket ring 20 fixed on the first turntable 8, thereby achieving a stable connection with the first turntable 8.

[0033] Preferably, the outside of the main shaft 14 is also fixedly mounted with limit blocks 17 located on both ends of the rotating sleeve 18 , and the rotation position of the rotating sleeve 18 can be stabilized by the limit blocks 17 .

[0034] In this embodiment, a second gear 23 is fixedly mounted on the outside of the traction shaft 21, and the second gear 23 is toothed and meshed with the second meshing wheel 19. Through the meshing of the second gear 23, the traction shaft 21 can simultaneously drive the rotating sleeve 18 and the main shaft 14 to rotate, and the rotation directions are opposite.

[0035] In this embodiment, the discharge structure includes an air duct 12 fixedly installed on one side of the bottom cylinder 2, a fan 13 connected by a hose is fixedly installed on the outside of the air duct 12, and a feeding pipe 11 that passes through and connects the cylinder 3 and the air duct 12 is also fixedly installed inside the bottom cylinder 2.

[0036] Preferably, the feed pipe 11 is located at the bottom of the bottom cylinder 2, and a partition net should be installed on the surface of the feed pipe 11. The bottom cylinder 2 and the cylinder 3 are installed obliquely to the base 1, and air is blown toward the outlet end of the air duct 12 by the fan 13, so that the finely chopped hay that naturally slides along the feed pipe 11 due to gravity can be blown out by the fan 13 to complete the discharge.

[0037] It should be noted that the feeding device includes a mounting frame 4 fixedly mounted on one end of the base 1, an L-shaped bracket 5 is rotatably mounted on the mounting frame 4, and a cylinder 6 rotatably connected to the bracket 5 is rotatably mounted on the base 1. By placing hay on the bracket 5, the cylinder 6 can be controlled to lift the hay and send it into the cylinder 3.

[0038] The working principle of the above embodiment is:

[0039] By turning on the motor 15, the motor 15 drives the traction shaft 21 to rotate, and the traction shaft 21 drives the meshed auxiliary wheel 25 through the first gear 22 and the second gear 23 fixedly connected to the outside to pull the first meshing wheel 16 and the second gear 23 to rotate. At this time, the main shaft 14 and the rotating sleeve 18 fixedly connected to the first meshing wheel 16 and the second gear 23 respectively rotate in the opposite direction, so that the second turntable 9 and the first turntable 8 fixedly connected to the main shaft 14 rotate, so that the cutting teeth 10 on the surfaces of the second turntable 9 and the first turntable 8 cut the hay under rotation, and by placing the hay on the bracket 5, the cylinder 6 is controlled to push the bracket 5 to rotate relative to the mounting frame 4, so that the bracket 5 puts the hay into the cylinder 3 under rotation, and releases the cutting teeth 10 for cutting, and the cut fine hay enters the air duct 12 along the feeding pipe 11 at the bottom of the bottom cylinder 2 and is blown out.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
