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 should fall within the scope of protection of the present application.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 3 , and describes the application in detail with reference to embodiments. Example 1

[0021] Embodiment 1 discloses a multifunctional feed harvesting and processing machine. Figure 1 , including a crawler-type traveling machine base 1, a harvesting unit 2, a cutting unit 3, a shredding unit 4, a first conveying unit 5, a second conveying unit 6 and a collecting box 7.

[0022] The harvesting unit 2 includes a harvesting head 201 disposed on the left side of the crawler travel machine base 1, the lower left end of the harvesting head 201 is provided with a tooth-shaped tip, and a feeding auger 202 is provided inside the harvesting head 201. At the same time, a reel 203 is rotatably provided above the harvesting head 201, and a first hydraulic telescopic rod 204 is provided on the harvesting head 201 for driving the reel 203 to be lifted or extended into the harvesting head 201, so that the reel 203 pushes the straw or grass into the harvesting head 201 during the forward movement of the machine, and the lower left end of the harvesting head 201 with a tooth-shaped tip cuts the straw or grass from the root, and the cut materials are transported to one point by the feeding auger 202.

[0023] The first conveying unit 5 includes a first conveying channel 501 connected to the right side of the harvesting head 201. The left end of the first conveying channel 501 is connected to the position where the feeding auger 202 collects materials, and the other end is tilted upward and connected to the cutting unit 3 on the crawler travel machine base 1. A chain scraper 502 is arranged in the first conveying channel 501, and the harvested materials can be conveyed to the cutting unit 3 through the chain scraper 502. In addition, in order to lift the harvesting unit 2 and the first conveying unit 5 and facilitate the movement of the entire machine, a second hydraulic telescopic rod 8 is also arranged on the crawler travel machine base 1, and then the telescopic end of the second hydraulic telescopic rod 8 is connected to the first conveying channel 501.

[0024] The cutting and mixing unit 3 includes a chassis 301 fixed on the crawler travel machine base 1, a feed port connected to the upper end of the first conveying channel 501 is arranged at the lower left end of the chassis 301, and a longitudinal cutter 302 extending into the interior of the chassis 301 is installed at the bottom of the feed port, a cutting knife holder 303 is rotatably arranged inside the chassis 301, and a plurality of cutting knives 304 are fixedly installed on the outer circumferential surface of the cutting knife holder 303. When the cutting knife holder 303 rotates in the chassis 301, the blade of the cutting knife 304 will approach the blade of the longitudinal cutter 302, thereby cutting the straw or grass fed in.

[0025] In addition, the plurality of cutting blades 304 in this embodiment are all mounted on the cutting blade holder 303 at a certain tilt angle (see attached Figure 2), so that when the cutting knife 304 approaches the longitudinal cutter 302, one end of the cutting knife 304 first approaches the longitudinal cutter 302, and then gradually moves the blade of the cutting knife 304 to the longitudinal cutter 302 successively, so that the original line cutting method of the cutting knife 304 and the longitudinal cutter 302 is changed to a point cutting method, which effectively reduces the running resistance during the straw cutting process and reduces the power requirement for the power source. At the same time, a silo 305 is installed at the upper end of the chassis 301, and a wheel groove type quantitative feeding device 306 is provided at the lower end of the silo 305. During the silage processing process, other auxiliary materials in the silo 305 can be added to the chassis 301 through the wheel groove type quantitative feeding device 306 and mixed with the cut straw or green grass fragments.

[0026] The second conveying unit 6 includes a second conveying channel 601 connected to the right end of the chassis 301, the second conveying channel 601 is vertically arranged upward, and a material discharge chute 602 is arranged on the top right side of the second conveying channel 601. A vertically arranged conveyor belt scraper 603 is arranged in the second conveying channel 601, and the lower end of the conveyor belt scraper 603 is extended to the lower right end of the inner cavity of the chassis 301, and the upper end is extended to the position of the material discharge chute 602. In order to facilitate the automatic movement of the cut materials and the added auxiliary materials to the lower end of the conveyor belt scraper 603, the bottom wall of the chassis 301 is also designed to be tilted downward from left to right.

[0027] The kneading unit 4 includes a bracket 401 arranged on the crawler-type traveling machine base 1 on the right side of the second conveying unit 6, a kneading drum 402 is connected to the upper end of the bracket 401, the upper left end of the kneading drum 402 is connected to the material discharge chute 602, and a discharge end 403 is arranged at the right end of the kneading drum 402. A kneading knife holder 404 is coaxially mounted inside the kneading drum 402 (see attached Figure 3 ), a row of kneading blades 405 are rotatably mounted on a plurality of knife rods 405 evenly arranged in the circumferential direction of the kneading knife holder 404. In addition, in order to ensure the kneading effect on the material, a plurality of convex racks 406 are arranged at intervals on the lower half of the inner wall of the kneading cylinder 402. The design of the convex racks 406 can increase the resistance of the material moving from the bottom of the kneading cylinder 402 to the discharge end 403, thereby increasing the number and time of the kneading blades 405 acting on the material, thereby improving the kneading effect of the material.

[0028] The collection box 7 is installed on the crawler travel machine base 1 on the right side of the bracket 401, and its upper end opening is aligned with the discharge end 403. In addition, a corresponding gate can be set on one side of the collection box 7 to facilitate the centralized discharge of the processed silage feed. Finally, the drive system in this embodiment is of conventional design, and can use motor direct drive or use belts, chains and other transmission components for power transmission, so that one motor can drive multiple units to operate at the same time.

[0029] During the operation of the multifunctional forage harvesting and processing machine disclosed in this embodiment 1, the crawler-type traveling machine base 1 moves the entire machine to the straw rice field, controls the second hydraulic telescopic rod 8 to retract, lowers the entire harvesting unit 2 and the first conveying unit 5, until the lower end of the harvesting head 201 is flush with the ground, and then controls the second hydraulic telescopic rod 8 to retract, thereby lowering the reel 203 into the harvesting head 201.

[0030] Next, the power systems of the harvesting unit 2, the cutting unit 3, the kneading unit 4, the first conveying unit 5, and the second conveying unit 6 are started to operate synchronously, and the entire machine is advanced through the crawler-type traveling machine base 1. During the advancement of the machine, the straw is pushed into the harvesting head 201 by the reel 203, and the straw is cut from the root by the left lower end of the harvesting head 201 with a tooth-shaped tip. The cut material is transported to the lower end of the first conveying unit 5 by the feeding auger 202, and then the harvested straw is sent to the longitudinal cutter 302 at the feed port of the chassis 301 by the first conveying unit 5, and then the cutting knife 304 is driven by the cutting knife holder 303 to rotate in the direction of the longitudinal cutter 302, and then the fixed-length cutting of the straw is completed under the shearing force of the cutting knife 304 and the longitudinal cutter 302, and at the same time, the wheel groove type quantitative feeding device 306 quantitatively adds other auxiliary materials in the silo 305 into the chassis 301 to mix with the cut straw fragments.

[0031] The stirred and mixed material is transported upward by the second conveying unit 6 and then falls into the kneading drum 402. The multiple rows of kneading blades 405 in the kneading drum 402 rotate at high speed driven by the kneading knife holder 404 and act on the material to complete the kneading action. After the kneading is completed, it is finally discharged from the discharge end 403 into the collection box 7 for collection.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
