[0042] One of the auxiliary pressure rollers 10 is driven by a second motor 26, and the auxiliary pressure roller 10 driven by the second motor 26 is connected to the main pressure roller 11 through a chain 25. The two auxiliary pressure rollers 10 are connected through a driving gear 23 and a driven gear 24 arranged at the shaft ends.

[0043] Specifically, the grass-cutting mechanism 20 includes a grass-cutting main shaft 8, and eight cutters 9 are distributed at intervals in the circumferential direction outside the grass-cutting main shaft 8.

[0044] Specifically, the grass kneading mechanism 22 includes a grass kneading main shaft 5 , and three side rollers 4 are distributed at intervals in the circumferential direction outside the grass kneading main shaft 5 , and the side rollers 4 are used to support the kneading blades 3 .

[0045] Specific as Figure 8 As shown, a plurality of kneading kneading blades 3 are placed on the grass kneading main shaft 5 at intervals and fixed on the grass kneading main shaft 5 by welding. A plurality of through holes are distributed circumferentially on the kneading blades 3, and the side support rollers 4 pass through the through holes on the kneading blades 3 in sequence.

[0046] In this embodiment, an anti-clogging discharging mechanism 40 is provided below the grass kneading mechanism 22. The anti-clogging discharging mechanism 40 includes a conveying auger 34 and a discharging fan 35 provided at one end of the conveying auger 34. The discharging fan 35 includes a baffle 46 and four blades 45 welded on the baffle 46. The conveying auger 34 is located in the auger groove 41 at the lower part of the grass kneading chamber 38.

The second feed port 15 is also provided with a vertical second guide groove 50 . The cross-section of the second guide groove 50 is U-shaped, and the second material baffle 19 can move in a directional manner along the second guide groove 50 .

[0050] Principle: the material after passing through the grass kneading mechanism 22 falls into the auger groove 41, and is transported to the blades 45 of the discharge fan 35 by the conveying auger 34. The centrifugal force generated by the high-speed rotation of the fan throws the material on the blades out of the second discharge port 33; when it is necessary to crush corn kernels or other similar materials, the screen 48 is inserted into the screen groove 49, and the material enters from the second feed port 15. The second material baffle 19 can be inserted into the second guide groove 50 to prevent the material from splashing. After being crushed by the grass kneading mechanism 22, it falls into the screen groove 49. The material filtered by the screen groove 49 passes through the conveying auger mechanism 34 and the discharge fan 35, and is finally discharged from the second discharge port 33.

[0051] In this embodiment, the blade of the chopper 9 is axially parallel to the grass-chopping main shaft 8. The chopper 9 is arranged on a chopper bracket 31 outside the grass-chopping main shaft 8. The chopper bracket 31 is welded to the grass-chopping main shaft 8.

[0058] In this embodiment, a first discharge port 32 is provided at an upper and oblique side of the grass cutting chamber 37 and the grass kneading chamber 38 .

[0059] Among them, a first material baffle 18 is detachably provided at the first discharge port 32, and an inclined first guide groove 30 is provided at the first discharge port 32. The cross-section of the first guide groove 30 is U-shaped, and the inclination angle of the first guide groove 30 is α, α is 45°, and the first material baffle 18 can move in a directional manner along the first guide groove 30.

[0060] Principle: When the material needs to be chopped and kneaded, the first material baffle 18 is inserted into the first guide groove 30, and the third material baffle 44 is moved out of the third guide groove 43. The material passes through the grass-chopping mechanism 20 and enters the grass-kneading mechanism 22, and is finally discharged from the first discharge port 32. When the material only needs to be chopped, the first material baffle 18 is moved out of the first guide groove 30, and the third material baffle 44 is inserted into the third guide groove 43. The material passes through the grass-chopping mechanism 20 and is directly discharged from the first discharge port 32, thereby realizing the separation of mixed materials without disassembly.

[0063] Among them, the active speed regulating gear group 101 and the driven speed regulating gear group 501 both include a first gear and a second gear, and the diameter of the first gear is larger than the diameter of the second gear. The large gear and the small gear are arranged on the sleeve with a front and rear interval, and the sleeve can be moved and adjusted on the support shaft or the grass kneading main shaft 5.

[0064] The sleeve and the support shaft are matched by splines, so that the sleeve can only move in one direction along the axial direction of the support shaft, and the sleeve can rotate with the support shaft.

[0065] The side wall of the sleeve is provided with a threaded hole, and a threaded pin penetrates the threaded hole and is pressed against the support shaft to achieve positioning.

[0066] A limit plate fixed by bolts is provided at the end of the support shaft to prevent the sleeve from falling off the support shaft.

[0067] By moving and adjusting, the first gear is meshed with the small-diameter gear 82 or the second gear is meshed with the large-diameter gear 81. Through the meshing of gears of different diameters, the rotation speed of the guillotine 9 or the kneading knife 3 is adjusted to obtain materials with different degrees of crushing, meet different processing requirements, and improve the flexibility of the overall equipment.

[0068] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "upper", "lower", "back", "top", "bottom", "inside", "outside" and other terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of this specification, which are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.

[0069] In addition, in the description of this specification, “plurality” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
