[0048] The following detailed implementation manners are provided to help the reader obtain a comprehensive understanding of the methods, devices, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent after understanding the disclosure of the present application. For example, the order of the operations described herein is merely exemplary and is not limited to the order set forth herein, but rather changes that will be apparent after understanding the disclosure of the present application may be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0049] The features described herein can be implemented in various forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatuses, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0050] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being “on” another element, “connected to” another element, “coupled to” another element, “above” another element, or “covering” another element, it can be directly “on,” “connected to,” “coupled to,” “above,” or “covering” the other element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being “directly on” another element, “directly connected to” another element, “directly coupled to” another element, “directly above” another element, or “directly covering” another element, there can be no other elements intervening therebetween.

[0051] As used herein, the term “and / or” includes any one of the listed related items and any combination of any two or more of them.

[0052] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another. Thus, a first component, element, region, layer, or part referred to in the examples described herein may also be referred to as a second component, element, region, layer, or part without departing from the teachings of the examples.

[0053] For ease of description, spatial relationship terms such as “above,” “upper,” “below,” and “lower” may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as “above” or “upper” relative to another element will then be “below” or “lower” relative to the other element. Thus, the term “above” includes both the orientation of “above” and “below” depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or at other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0054] The terms used herein are for describing various examples only and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. The terms "comprising", "including" and "having" enumerate the stated features, quantities, operations, components, elements and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0055] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Accordingly, the examples described herein are not limited to the specific shapes shown in the drawings, but include changes in shape that occur during manufacturing.

[0056] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible, as will be apparent after understanding the disclosure of the present application.

[0057] An embodiment of the present application discloses a grain bin of a corn harvester, as Figures 1 to 3 shown. The grain bin of the corn harvester mainly includes a grain bin main body 9, lifting guide columns 3, lifting guide rails 7, a lifting oil cylinder 4 and a tilting oil cylinder 5.

[0058] The lifting guide columns 3 are nested and slidably connected with the lifting guide rails 7. The lower ends of the lifting guide rails 7 are fixedly connected to the vehicle frame chassis 12, and the upper ends of the lifting guide columns 3 are hinged to the grain bin main body 9 through lifting guide column seat plates; the lower end of the lifting oil cylinder 4 is hinged to the lower end of the lifting guide rail 7, and the upper end of the lifting oil cylinder 4 is hinged to the lifting guide column seat plate; the lifting oil cylinder 4 can drive the lifting guide column 3 to slide along the lifting guide rail 7 and drive the grain bin main body 9 to perform a lifting action.

[0059] The upper end of the tilting oil cylinder 5 is hinged to the grain bin main body 9, and the lower end of the tilting oil cylinder 5 is hinged to the lower end of the lifting guide column 3 through a tilting oil cylinder seat plate 19; the tilting oil cylinder 5 can drive the grain bin main body 9 to perform a tilting action.

[0060] As Figure 2 shown, during field operation, the paddle wheel on the husker 10 rotates counterclockwise, conveys the corn ears from the front of the vehicle to the rear of the vehicle, and then enters the grain bin main body 9 through the grain bin inlet; as Figure 4 shown, after the grain bin is filled with corn ears, the lifting oil cylinder 4 extends, pushes the lifting guide column 3 to slide in the lifting guide rail 7, and when the stroke of the lifting oil cylinder 4 ends, the lifting guide column 3 is lifted in place; as Figure 5As shown, after the tilting cylinder 5 operates, it pushes the main body of the granary 9 to rotate clockwise around the upper rotating shaft of the lifting guide post 3. After the tilting cylinder 5 reaches the tilting position, the corn cobs in the main body of the granary 9 pour into the grain transport vehicle 15 along the arrow direction, completing the unloading; after the unloading is completed, the tilting cylinder 5 retracts, and the main body of the granary 9 rotates counterclockwise around the upper rotating shaft of the lifting guide post 3, and the main body of the granary 9 returns to its original position, as Figure 4 shown. Then, the lifting cylinder 4 retracts, the main body of the granary 9 drops, and returns to the field operation state, completing one unloading. When the granary is full of corn cobs and needs to be unloaded, the above process can be repeated.

[0061] In a preferred embodiment, the neutral planes of the lifting cylinder 4 and the tilting cylinder 5 coincide and are coplanar in the front-back direction of the vehicle. The design without staggering in the front-back direction of the vehicle can effectively compress the space, making the structure compact, which is beneficial to increasing the volume of the main body of the granary 9 and improving the operation efficiency.

[0062] An inlet seal plate 11, a spring 13 and a limit block 14 are arranged at the position of the inlet of the granary. Slide rails are respectively arranged on both sides of the inlet of the main body of the granary 9, and bearings are respectively arranged on both sides of the inlet seal plate 11. Through the cooperation of the bearings and the slide rails, the inlet seal plate 11 can slide relative to the main body of the granary 9, thereby opening or covering the inlet.

[0063] Two springs 13 are also arranged on both sides of the inlet seal plate 11. The upper ends of the springs 13 are connected to the inlet seal plate 11, and the lower ends are connected to the main body of the granary 9. When the inlet seal plate 11 opens the inlet, the springs 13 are in a stretched state.

[0064] At least one limit block 14 is arranged at the upper end of the inlet, which is used to limit the maximum displacement position of the inlet seal plate 11 to prevent the inlet seal plate 11 from coming out.

[0065] The upper edge of the inlet seal plate 11 is also provided with a bracket extending away from the main body of the granary 9 and used to contact the upper end of the peeling machine 10.

[0066] When the granary is full of corn cobs and needs to be emptied, the lifting oil cylinder 4 slowly extends, and the lifting guide column 3 drives the granary main body 9 to rise. The bracket on the feed port sealing plate 11 disengages from the upper end of the peeling machine 10, and the feed port sealing plate 11 falls back under the action of the spring 13 and its own gravity to block the feed port of the granary main body. When the tilting oil cylinder 5 tilts in place, the feed port sealing plate 11 is pulled back by the spring 13 to block the feed port, which can effectively prevent the corn cobs from leaking out of the feed port of the granary main body 9 and reduce corn losses. When the spring 13 fails, the limit block 14 can prevent the feed port sealing plate 11 from sliding out of the slide rail and falling to injure the operators near the grain carrier. After the unloading is completed, during the process of the granary falling back, the bracket on the feed port sealing plate 11 will contact the upper end of the peeling machine 10. As the granary main body 9 continues to fall back, the spring 13 will be stretched. When the granary main body 9 falls back in place completely, the spring 13 is fully stretched, and the feed port sealing plate 11 is located at the upper end of the feed port of the granary main body 9 to receive the corn cobs sent by the peeling machine 10.

[0067] The structure of the lifting guide column 3 is as Figure 7 and Figure 8 shown. The lifting guide column 3 is mainly composed of a front guide column 16, upper and lower guide column crossbeams 17, guide column diagonal tie rods 18, tilting oil cylinder seat plates 19, nylon blocks 20, and a rear guide column 21, etc. The upper end of the lifting guide column 3 is welded with a lifting guide column seat plate for hinging with the upper end of the lifting oil cylinder 4. The lower end of the lifting guide column 3 is provided with a tilting oil cylinder seat plate 19, and the lower end of the tilting oil cylinder 5 is hinged with the tilting oil cylinder seat plate 19. A nylon block 20 is installed at the lowermost end of the lifting guide column 3 to reduce the friction generated when the lifting guide column 3 slides in the lifting guide rail 7 and play a certain supporting role at the same time. The upper and lower guide column crossbeams 17 are used to fix the front guide column 16 and the rear guide column 21, and the guide column diagonal tie rods 18 are used to increase the rigidity and stability of the lifting guide column 3.

[0068] The structure of the lifting guide rail 7 is as Figure 9 and Figure 10 shown, and it is mainly composed of a nylon block 20, a front guide rail 22, a lifting oil cylinder seat plate 23, an oil cylinder safety clip 6, a guide rail diagonal tie rod 24, a rear guide rail 25, and a guide rail upper crossbeam 26, etc. A nylon block 20 is installed at the upper end of the lifting guide rail 7 to reduce the friction generated when the lifting guide column 3 slides in the lifting guide rail 7. The lifting guide rail 7 is welded with a lifting oil cylinder seat plate 23 on the outside for hinging with the lower end of the lifting oil cylinder 4. Both the lifting guide rail 7 and the lifting oil cylinder seat plate 23 are provided with strip-shaped slot holes for the sliding of the lifting guide column 3, and the lifting oil cylinder seat plate 23 also plays a role in strengthening the structural strength. A seat plate for installing the oil cylinder safety clip 6 is welded on the front guide rail 22. The guide rail upper crossbeam 26 is used to fix the front guide rail 22 and the rear guide rail 25, and the guide rail diagonal tie rod 24 is used to increase the rigidity and stability of the lifting guide rail 7.

[0069] The lifting guide post 3 and the lifting guide rail 7 are made of seamless rectangular tubes, which have high structural strength and can prevent the rectangular tubes from cracking during machining and grooving. In addition, the profiles are regular and the production cost is low.

[0070] A flap 1 and a flap mechanism 2 are provided at the discharge opening of the granary main body 9; as Figure 11 shown, the flap mechanism 2 includes a steel wire rope 27, a flap hinge 28, a pulley 29 and a slide plate 30;

[0071] One side of the flap hinge 28 is arranged on the granary main body 9, and the other side is fixedly connected to the flap 1, so that the flap 1 can rotate around the flap hinge 28; the pulley 29 is rotatably arranged on the granary main body 9; the slide plate 30 is a long strip plate, one end of which is installed on the flap 1, and a strip-shaped chute is arranged on the slide plate 30, and a branch pipe protruding outward is arranged on the granary main body 9, and the chute is connected to the branch pipe, so that the slide plate 30 can slide relative to the branch pipe; the steel wire rope 27 bypasses the pulley 29, one end is connected to the outer end of the slide plate 30, and the other end is connected to the lifting guide post seat plate.

[0072] During the overturning process of the granary main body 9, the chute of the slide plate 30 slides from one point to another point, and the flap 1 rotates around the flap hinge 28 from having a certain angle with the inclined plane of the granary discharge opening to being parallel to the inclined plane of the granary discharge opening, so as to facilitate discharging. At this time, the flap 1 can also increase the distance between the grain transport vehicle and the corn harvester, prevent the grain transport vehicle from rubbing against the corn harvester, and thus improve the flexibility of the operation of the grain transport vehicle. When the granary main body 9 falls back, under the restraint of the steel wire rope 27, the notch of the chute of the slide plate 30 slides from one point to another point in the reverse direction, and the flap 1 rotates around the flap hinge 28 from being parallel to the inclined plane of the granary discharge opening to having a certain angle with the inclined plane of the granary discharge opening. Finally, the granary main body 9 returns to its original position and returns to the field operation state.

[0073] Preferably, an oil cylinder safety clamp seat is arranged on the lifting guide rail 7, and three jacks arranged in the vertices of an isosceles triangle are arranged on the oil cylinder safety clamp seat; two of the jacks form a first group of jacks, and the included angle between the connection line thereof and the extending direction of the lifting guide rail 7 is greater than or equal to 80°, preferably close to a vertical relationship; the other two jacks form a second group of jacks, and the included angle between the connection line thereof and the extending direction of the lifting guide rail 7 is less than 10°, preferably close to a parallel relationship.

[0074] An oil cylinder safety clamp 6 is also included, and the oil cylinder safety clamp 6 is provided with at least two insertion parts.

[0075] When the oil cylinder safety clamp 6 is not in use, it is installed in the second group of jacks, and does not interfere with the actions of the lifting guide post 3, the lifting oil cylinder 4 and the overturning oil cylinder 5.

[0076] When the granary main body 9 is in a maintenance state, retract the lifting oil cylinder 4, extend the tilting oil cylinder 5 by a certain stroke to tilt up the granary main body 9, and then install the oil cylinder safety clamp 6 on the first group of jacks of the oil cylinder safety clamp seat through the insertion part and the jack to provide a certain supporting force for the granary main body 9, prevent the granary main body 9 from falling due to the pressure relief of the hydraulic oil cylinder, and improve the safety of maintenance.

[0077] This embodiment also provides a harvesting system, including the corn harvester granary described above, so it has all the beneficial effects of the corn harvester granary, and will not be specifically described here.

[0078] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
