Detailed Description
The above and further features and advantages of the present invention will be apparent from the following, complete description of the invention, taken in conjunction with the accompanying drawings, wherein the described embodiments are merely some, but not all embodiments of the invention.

In this embodiment, the forage is fed into the mixing barrel 1c from the feeding mechanism 3, and the fodder chopper mechanism 2 in the mixing barrel 1c is driven by the driving motor 4 directly to crush the forage. Meanwhile, the feeding mechanism 3 feeds grass under the indirect drive of the driving motor 4. In operation, if the amount of fodder in the mixing barrel 1c is too large, the guillotine mechanism 2 is fully loaded or even overloaded, and its rotational speed is correspondingly reduced. If the amount of fodder in the mixing barrel 1c is too small, the guillotine mechanism 2 is nearly unloaded, and the corresponding rotational speed thereof is also increased.
The feeding mechanism 3 in this embodiment is shown in fig. 2, and includes a driving roller 3a, a driven roller 3b, a driven positioning shaft 3c, a shaft sleeve connecting sleeve 3d, a driving gear 3e, a first transmission gear 3f, a second transmission gear 3g, an encoder 3h, and a servo motor 3 i; the driving roller 3a is in transmission connection with the guillotine mechanism 2; the driven roller 3b and the driven positioning shaft 3c are positioned above the driving roller 3a and are fixedly connected through a shaft sleeve connecting sleeve 3 d; the driving gear 3e is fixedly connected to the driving roller 3a, the second transmission gear 3g is movably connected to the driven positioning shaft 3c, and the driving gear 3e is meshed with the second transmission gear 3g through the first transmission gear 3 f; the encoder 3h is connected with the second transmission gear 3g and used for detecting the rotating speed of the second transmission gear 3g, the servo motor 3i is connected with the driven positioning shaft 3c and used for adjusting the angular displacement of the driven positioning shaft 3c according to the rotating speed of the second transmission gear 3g, and the distance between the driving roller 3a and the driven roller 3b is adjusted according to the angular displacement of the driven positioning shaft 3 c. During operation, if the rotating speed of the guillotine mechanism 2 is reduced, the rotating speed correspondingly fed back to the second transmission gear 3g is reduced, and the encoder 3h detects the reduction of the rotating speed, so that the servo motor 3i can be controlled to generate the angular displacement in the anticlockwise direction, and the driving roller 3a and the driven roller 3b are adjusted to be small, and the forage amount which can be fed by the feeding mechanism 3 is reduced. If the rotating speed of the guillotine mechanism 2 rises, the rotating speed correspondingly fed back to the second transmission gear 3g rises, and the encoder 3h detects the rising speed and can control the servo motor 3i to generate the clockwise angular displacement, so that the driving roller 3a and the driven roller 3b are enlarged, and the forage amount which can be fed by the feeding mechanism 3 is increased. Therefore, the equipment is mainly used for controlling the grass feeding amount, so that the operation is simpler without much experience of an operator.
In one embodiment, as shown in FIG. 2. The agricultural grass chopper provided by the embodiment further comprises a frame 1. And the frame 1 comprises a first side plate 1a, a second side plate 1b, and a stirring barrel 1c formed between the first side plate 1a and the second side plate 1 b; the driving roller 3a, the driven roller 3b and the driven positioning shaft 3c are fixed between the first side plate 1a and the second side plate 1 b; the driving gears 3e comprise two driving gears and are respectively arranged on the outer sides of the first side plate 1a and the second side plate 1 b; the first transmission gear 3f and the second transmission gear 3g are arranged on the outer side of the first side plate 1 a; the shaft sleeve connecting sleeves 3d comprise two parts and are respectively arranged at the outer sides of the first side plate 1a and the second side plate 1 b; the encoder 3h is arranged outside the first side plate 1 a; the servo motor 3i is provided outside the second side plate 1 b.

And such a staggered arrangement of the elements helps to compact the fodder. In a preferred embodiment, the number of the first outer ring gears 3a1 is larger than the number of the second outer ring gears 3b 1. Since the driving roller 3a is located below the driven roller 3b, the number of the first outer ring gears 3a1 is larger than that of the second outer ring gears 3b1, so that the forage can be prevented from accidentally scattering in the process of being fed into the mixer barrel 1 c.

In this embodiment, the motor pulley 2b drives the rotating shaft 2a to rotate the feeding driving gear 2d, the cross blade holder 2c and the blade 2e on the rotating shaft 2a, and the forage is cut up by the blade 2e close to the inner side wall of the mixing barrel 1 c. As shown in FIG. 4b, the four ends of the cross blade holder 2c are respectively connected with the blade 2e, any one end and the blade 2e form a T-shaped structure, a V-shaped gap is formed between two adjacent ends, and the T-shaped structure compresses the space between the blade 2e and the inner side wall of the stirring barrel 1 c. The forage falls from the V-shaped gap after being cut by the blade 2e on one end portion, and is cut by the blade 2e on the other end portion. The above repeated cutting process forms a cycle when the guillotine mechanism 2 rotates, and the space provided by the V-shaped gap helps to form a cycle.

In this embodiment, and by way of example as shown in figure 5, the guillotine mechanism 2 can chop fodder as the blade 2e rotates anticlockwise. When the blade 2e rotates clockwise, the guillotine mechanism 2 can clear the chopped forage. Also, during the grass chopping process by the blade 2e, the flexible piece 2e5 is closely attached to the inner side wall of the barrel 1c, and the space between the blade 2e and the inner side wall of the barrel 1c can be further compressed.
