[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0039] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0040] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] like Figure 2-3 As shown, a corn harvester for harvesting both stalks and ears includes a frame 40;

[0042] A straw harvesting header (not shown), a feeding mechanism (not shown), a crusher (not shown), a throwing blower 20 and a straw throwing mechanism 10 are installed on the vehicle frame 40 and connected in sequence;

[0043] Among them, the straw harvesting header is used to cut off the straw from the root, the feeding mechanism is used to transport the cut straw to the crusher, the crusher is used to chop the straw and throw the grass to the throwing blower, and the chopped grass is thrown to the following truck or hay bin 30 through the grass throwing mechanism 10 under the action of the throwing blower 20.

[0044] Further, such as Figure 3 As shown, the forage throwing mechanism 10 includes a vertical throwing portion 1 and an arc-shaped throwing portion 2 connected in sequence. The vertical throwing portion 1 is fixed to the vehicle frame 40; the arc-shaped throwing portion 2 is rotatably mounted on the vertical throwing portion 2, so that the arc-shaped throwing portion 2 can spray the forage into the forage bin 30 or the forage collection vehicle accompanying the corn harvester. Since the arc-shaped throwing portion 2 is rotatably mounted on the vertical throwing portion 2, the forage throwing mechanism 10 can throw the forage into the accompanying vehicle or into the forage bin of the corn harvester, making the forage throwing mechanism 10 multi-purpose and enabling the stalk-and-ear corn harvester to be suitable for different occasions.

[0045] Further, such as Figure 4 As shown, the arc-shaped ejection part 2 includes a central sleeve 23, an arc-shaped spray barrel, a spray barrel cap 24, an ejection cylinder 25, and an electric push rod (not shown). The central sleeve 23, the arc-shaped spray barrel, and the spray barrel cap 24 are connected in sequence. The central sleeve 23 is rotatably mounted on the vertical ejection part 1. One end of the arc-shaped spray barrel is hingedly mounted on the central sleeve 23, and the spray barrel cap 24 is hingedly mounted on the other end of the arc-shaped spray barrel. One end of the ejection cylinder 25 is hingedly connected to the central sleeve 23, and the other end is hingedly connected to the arc-shaped spray barrel. The electric push rod has one end hingedly connected to the arc-shaped spray barrel and the other end is hingedly connected to the spray barrel cap 24. The ejection cylinder 25 and the electric push rod are used to adjust the angles of the arc-shaped spray barrel and the spray barrel cap 24 respectively, thereby achieving secondary adjustment of the grass material spraying angle, making the ejection mechanism angle adjustment more precise, and thus making the ejection mechanism outlet better aligned with the grass bin or accompanying truck.

[0046] Further, such as Figure 4-5 As shown, the arc-shaped spray barrel includes a basic spray barrel 21 and an extended spray barrel 22. The central sleeve 23, the basic spray barrel 21, the extended spray barrel 22, and the spray barrel cap 24 are sequentially connected. One end of the basic spray barrel 21 is hingedly mounted to the upper end of the central sleeve 23. The addition of the extended spray barrel 22 to the arc-shaped throwing portion 2 reduces the following distance requirement for the accompanying truck, thereby reducing the requirements for the drivers of the corn harvester and accompanying vehicles, and greatly reducing the occurrence of forage falling on the ground.

[0047] Further, such as Figure 5-11 As shown, the basic spray barrel 21 includes a pair of basic spray barrel side panels 211, a basic spray barrel top panel 212 installed on the upper ends of the pair of basic spray barrel side panels 211, and a basic spray barrel bottom panel 213 installed on the lower ends of the pair of basic spray barrel side panels 211. The pair of basic spray barrel side panels 211, the basic spray barrel top panel 212 and the basic spray barrel bottom panel 213 together form the basic spray barrel 21, and the end of the basic spray barrel 21 close to the extended spray barrel 22 is a through port 214; the end of the basic spray barrel bottom panel 213 away from the center sleeve 23 is provided with a notch 215, and a grass guide plate 218 is provided at the through port 214. When the forage throwing mechanism 10 throws forage to the accompanying vehicle, the forage guide plate 218 does not block the passage opening 214, which is open. The forage continuously passes through the basic spray barrel 21 and the extended spray barrel 22, and enters the accompanying vehicle through the spray barrel cap 24. When the forage throwing mechanism 10 throws forage to the hay bin 30, the forage guide plate 218 blocks the passage opening 214, which is closed, and the forage falls into the hay bin 30 through the notch 215. This arrangement cleverly solves the problem of how to selectively spray forage to the hay bin 30 or the accompanying vehicle after the extended spray barrel 22 is added to the arc-shaped throwing portion 2.

[0048] Furthermore, a pair of the basic spray barrel side panels 211 are fixedly mounted with side panel reinforcement ribs 219 , and a rotating lug 2191 is fixedly mounted on the side panel reinforcement ribs 219 . The forage guide plate 218 is rotatably mounted between the pair of rotating lugs 2191 and is driven by the guide plate power unit 26 .

[0049] Furthermore, a rotating shaft 2192 is provided between the rotating ears 2191 , the forage guide plate 218 is fixedly connected to the rotating shaft 2192 , and the rotating shaft 2192 is transmission-connected to the guide plate power unit 26 .

[0050] Further, combined Figure 8 As shown, the guide plate power unit 26 includes an electric telescopic rod 261, a grass spraying guide control arm 262 and a fixed rod 263. The fixed rod 263 is fixedly mounted on the basic spray barrel side plate 211, and the grass spraying guide control arm 262 is fixedly connected to the rotating shaft 2192. One end of the electric telescopic rod 261 is hingedly mounted on the fixed rod 263, and the other end is hingedly mounted on the grass spraying guide control arm 262. Through the above arrangement, when the grass throwing mechanism 10 throws the grass to the accompanying vehicle, the electric telescopic rod 261 is shortened, the grass spraying guide control arm 262 swings forward, driving the grass guide plate 218 to rotate upward, and the grass guide plate 218 does not block the passage 214. The grass continuously passes through the basic spray barrel 21 and the extended spray barrel 22 and enters the accompanying vehicle from the spray barrel cap 24; when the grass throwing mechanism 10 throws the grass to the grass bin 30, the electric telescopic rod 261 is extended, the grass spraying guide control arm 262 swings backward, driving the grass guide plate 218 to rotate downward, and the grass guide plate 218 blocks the passage 214, and the grass falls into the grass bin 30 from the gap 215; the structure is simple and optimized, and the switching of the working mode of the grass guide plate 218 is convenient. After adding the extended spray barrel 22 to the arc-shaped throwing part 2, the excellent effect of selectively spraying the grass to the grass bin 30 or the accompanying truck can be achieved.

[0051] Furthermore, the electric telescopic rod 261 includes an electric push rod and an electric push cylinder. The end of the electric push rod is equipped with a hinge column 2611, and the end of the electric push cylinder is provided with a hinge seat 2612. The hinge column 2611 is hingedly mounted on the grass spraying guide control arm 262, and the hinge seat 2612 is hingedly mounted on the fixed rod 263.

[0052] Furthermore, the grass spraying guide control arm 262 includes a swing arm 2621, a sleeve 2622 installed at the upper end of the swing arm 2621, and a bracket shaft 2623 installed at the lower end of the swing arm 2621. The sleeve 2622 is sleeved on the outside of the rotating shaft 2192, and the sleeve 2622 is connected to the rotating shaft 2192 through a fastener 264; the hinge column 2611 is hingedly installed on the bracket shaft 2623.

[0053] Furthermore, the extended spray barrel 22 includes a pair of extended spray barrel side panels 221, an extended spray barrel top plate 222 installed at the upper ends of the pair of extended spray barrel side panels 221, and an extended spray barrel bottom plate 223 installed at the lower ends of the pair of extended spray barrel side panels 221. The pair of extended spray barrel side panels 221, the extended spray barrel top plate 222 and the extended spray barrel bottom plate 223 together form the extended spray barrel 22; the basic spray barrel side panel 211 has an arc section 216 extending into the extended spray barrel 22 at one end away from the center sleeve 23.

[0054] Furthermore, a pair of the basic spray barrel side plates 211 are mounted with rotating side plates 217, the rotating side plates 217 protruding from the basic spray barrel top plate 212, the extended spray barrel 22 is mounted with a reinforcing frame plate 224, the reinforcing frame plate 224 is mounted with a rotating bracket 225, the rotating side plates 217 and the rotating bracket 225 are hingedly connected via a spray barrel fixing pin 226;

[0055] The size of the rotating side plate 217 matches the reinforced frame plate 224. With the above arrangement, when the grass throwing mechanism is in the retracted state, the bottom end of the basic spray barrel 21 abuts against the front plate of the grass bin 30, and the bottom end of the extended spray barrel 22 abuts against the rear plate of the grass bin 30. The curved spray barrel is "bent" and the overall height of the curved spray barrel is the same as the retracted height of the conventional technique without the extended spray barrel 22. The addition of the extended spray barrel 22 does not increase the overall height of the corn harvester, nor does it affect the transportability of the corn harvester during transfer.

[0056] Furthermore, an electric push rod cover 2193 is installed on the side plate reinforcement rib 219, and the electric telescopic rod 261 is installed in the electric push rod cover 2193. By setting the electric push rod cover, the electric telescopic rod is protected to prevent electronic products from being damaged by the environment.

[0057] The foregoing is an example of the best mode of carrying out the present invention. Any portion not described in detail herein is common knowledge within the skill of one of ordinary skill in the art. The scope of protection of the present invention is determined by the claims. Any equivalent transformation based on the technical teachings of the present invention is also within the scope of protection of the present invention.
