Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment technology, and more particularly to a grain storage facility and a harvesting system. Background Technology

[0002] Corn is an important food crop in my country, with a large planting area and wide distribution. In recent years, the degree of mechanization in corn harvesting has been continuously deepening, the machine harvesting rate has been steadily increasing, and the intensity of manual labor has been greatly reduced.

[0003] The grain bin, a key component of the corn harvester, primarily receives corn ears from the preceding component during field operations. Once full, a hydraulic cylinder tilts the bin, dumping the corn ears into the grain truck. Currently, most corn harvesters on the market lack a baffle at the grain bin inlet. Figure 1 As shown, when the corn ears are poured out after the grain bin 5 is overturned, the corn ears will leak out from the grain bin inlet in the direction of the arrow, which not only affects the efficiency of operation, but also increases the loss of corn ears. Utility Model Content

[0004] The purpose of this application is to provide a grain silo and a harvesting system that can effectively block the grain silo inlet when dumping corn ears, so as to prevent corn ears from leaking out of the grain silo inlet.

[0005] This application provides a grain silo, including a grain silo body, a grain silo support frame, and a tilting cylinder. The unloading end of the grain silo body is connected to one end of the grain silo support frame via a rotating shaft. One end of the tilting cylinder is hinged to a vehicle chassis, and the other end is hinged to the grain silo body. The grain silo body can tilt around the rotating shaft under the drive of the tilting cylinder.

[0006] It also includes a feed inlet baffle and a crank-connecting rod mechanism;

[0007] The crank of the crank-connecting rod mechanism is responsively connected to the tilting cylinder, and the connecting rod of the crank-connecting rod mechanism is connected to the feed inlet baffle.

[0008] Guide structures are provided on both sides of the feed inlet of the main body of the grain silo. The feed inlet baffle can slide along the guide structure and open or block the feed inlet under the drive of the crank-connecting rod mechanism.

[0009] In a preferred embodiment, when the tilting cylinder retracts to its shortest length, the crank-connecting rod mechanism drives the feed inlet baffle to open the feed inlet;

[0010] When the tilting cylinder extends to its maximum length, the crank-connecting rod mechanism drives the feed inlet baffle to block the feed inlet;

[0011] In a preferred embodiment, the guide structure is a chute, and sliders are respectively provided on both sides of the feed inlet baffle, so that the feed inlet baffle can slide along the chute.

[0012] In a preferred embodiment, one end of the crank is hinged to the main body of the grain bin, and the other end is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the feed inlet baffle.

[0013] In a preferred embodiment, the crank and the tilting cylinder are connected by a power rod drive.

[0014] In a preferred embodiment, the power rod includes a first rod and a second rod that are hinged to each other. The outer end of the first rod is hinged to the extended end of the tilting cylinder, and the outer end of the second rod is hinged to the middle position of the crank.

[0015] In a preferred embodiment, the guide structure is a slide rail, and the feed inlet baffle is provided with slide grooves on both sides, so that the feed inlet baffle can slide along the slide rail.

[0016] In a preferred embodiment, the grain silo support is inclined relative to the horizontal plane.

[0017] In a preferred embodiment, the grain silo further includes a support rod, one end of which is fixedly connected to the chassis frame, and the other end is fixedly connected to the grain silo support.

[0018] Secondly, this application also provides a harvesting system, including the grain silo described in any one of the claims.

[0019] Compared with the prior art, this application has the following beneficial effects:

[0020] This application adds a crank-connecting rod mechanism and a feed inlet baffle to the grain bin. The crank in the crank-connecting rod mechanism is connected to the tilting cylinder as a power rod. When the grain bin of the corn harvester tilts up to unload the grain, the feed inlet baffle rises under the action of the crank-connecting rod mechanism to block the feed inlet of the grain bin and prevent corn ears from leaking out. When the tilting cylinder retracts and the grain bin returns to the field for harvesting, the feed inlet baffle retracts under the action of the crank-connecting rod mechanism, opening the feed inlet of the grain bin to facilitate receiving corn ears delivered by the previous component. This solution uses mechanical structural components, has a simple structure, and high reliability.

[0021] This application also provides a harvesting system including the aforementioned grain silo, and thus possesses all the beneficial effects of a grain silo, which will not be specifically described here. Attached Figure Description

[0035] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0036] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0037] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0038] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0039] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0040] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0041] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0042] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0044] This application discloses a grain silo, including a grain silo body 5, a grain silo support 2, and a tilting cylinder 3. The unloading end of the grain silo body 5 is connected to one end of the grain silo support 2 via a rotating shaft 1. One end of the tilting cylinder 3 is hinged to the chassis 4, and the other end is hinged to the front of the grain silo body 5. The grain silo body 5 can tilt around the rotating shaft 1 under the drive of the tilting cylinder 3. A feed inlet is provided at the upper front position of the grain silo body 5.

[0045] It also includes a feed inlet baffle 10 and a crank-connecting rod mechanism, wherein the working principle of the crank-connecting rod mechanism is as follows: Figure 2 As shown:

[0046] When crank 1-1 rotates clockwise around the pivot point O, the outer end of crank 1-1 rotates from point A to point B, and connecting rod 1-2 drives slider 1-3 to slide from point C to point D. When crank 1-1 rotates counterclockwise around the pivot point O, the outer end of crank 1-1 rotates from point B to point A, and connecting rod 1-2 drives slider 1-3 to slide from point D to point C.

[0047] Move it to the grain silo inlet location, such as... Figures 3 to 5 As shown, the crank 7 of the crank-connecting rod mechanism is connected to the tilting cylinder 3, and the connecting rod 8 of the crank-connecting rod mechanism is connected to the feed inlet baffle 10.

[0048] Guide structures are provided on both sides of the feed inlet of the main body 5 of the grain silo. The feed inlet baffle 10 can slide along the guide structure and open or block the feed inlet under the drive of the crank connecting rod mechanism.

[0049] Specifically, the guide structure is a chute 9, and sliders are respectively provided on both sides of the feed inlet baffle 10 so that the feed inlet baffle 10 can slide along the chute 9.

[0050] One end of the crank 7 is hinged to the main body 5 of the grain bin, and the other end is hinged to one end of the connecting rod 8. The other end of the connecting rod 8 is hinged to the feed inlet baffle 10.

[0051] The crank 7 and the tilting cylinder 3 are connected by a drive rod 12. The drive rod 12 includes a first rod and a second rod that are hinged to each other. The outer end of the first rod is hinged to the extended end of the tilting cylinder 3, and the outer end of the second rod is hinged to the middle position of the crank 7.

[0052] When the tilting cylinder 3 retracts to its shortest length, the crank connecting rod mechanism can drive the feed port baffle 10 to open the feed port;

[0053] When the tilting cylinder 3 extends to its maximum length, the crank-connecting rod mechanism can drive the feed inlet baffle 10 to block the feed inlet.

[0054] In other embodiments, the chute 9 can also be replaced by a slide rail, and chute is provided on both sides of the feed inlet baffle 10 so that the feed inlet baffle 10 can slide along the slide rail.

[0055] In a preferred embodiment, the grain silo support 2 is inclined relative to the horizontal plane and also includes a support rod 6. One end of the support rod 6 is fixedly connected to the chassis 4, and the other end is fixedly connected to the grain silo support 2. The support rod 6 can reinforce the grain silo support 2 and ensure the stability of the grain silo body when it is tilted.

[0056] When using it, the workflow is as follows:

[0057] S1: As Figure 3 As shown, this is the normal harvesting operation in the field. The lower end of the grain bin support 2 is bolted to the chassis 4; the lower end of the support rod 6 is bolted to the chassis 4, and the upper end is bolted to the grain bin support 2; the lower end of the tilting cylinder 3 is hinged to the grain bin support 2, and the upper end is hinged to the grain bin body 5; the grain bin body 5 and the grain bin support 2 are hinged together by the rotating shaft 1; a fulcrum for the rotation of the crank 7 is welded on the grain bin body 5, and a groove 9 for the sliding of the feed inlet baffle 10 is also welded on the grain bin body 5; the crank 7 is hinged to the connecting rod 8; the connecting rod 8 is hinged to the feed inlet baffle 10; one end of the first rod of the power rod 12 is connected to the upper end of the tilting cylinder 3, and the other end of the second rod is hinged to the crank 7;

[0058] S2: When the main body 5 of the grain silo is full of corn ears and needs to be unloaded, the tilting cylinder 3 pushes the main body 5 of the grain silo to rotate clockwise around the rotating shaft 1. At this time, the crank 7 rotates clockwise around the upper fulcrum of the main body 5 under the drive of the power rod 12. During the rotation, the crank 7 drives the connecting rod 8 to move. The connecting rod 8 pushes the feed inlet baffle 10 to slide upward in the slide groove 9. The intermediate state of the main body 5 during the tilting process is as follows: Figure 4 As shown, when the tilting cylinder 3 reaches its stroke position, the feed inlet baffle 10 also slides into position under the action of the connecting rod 8, blocking the grain bin feed inlet. Figure 5 As shown, this is also the state of the main body of the grain warehouse 5 with corn ears tilted over;

[0059] S3: As Figure 5 As shown, after the corn ears in the main body 5 of the grain silo are tilted out, the tilting cylinder 3 retracts, pushing the main body 5 of the grain silo to rotate counterclockwise around the rotating shaft 1. At this time, the crank 7 rotates counterclockwise around the upper fulcrum of the main body 5 under the drive of the power rod 12. During the rotation, the crank 7 drives the connecting rod 8 to move, and the connecting rod 8 drives the feed inlet baffle 10 to slide downward in the slide groove 9. The intermediate state of the main body 5 during the tilting process is as follows: Figure 4 As shown, when the tilting cylinder 3 is fully retracted, the feed inlet baffle 10 also retracts into place under the action of the connecting rod 8, exposing the grain bin feed inlet, making it convenient to receive the corn ears conveyed by the previous component, such as... Figure 3 As shown, the harvesting operation has now returned to normal in the field.

[0060] This design can block the feed inlet of the corn harvester's grain bin when it is tilted up to unload, preventing corn ears from leaking out; when the grain bin returns to the field for harvesting, the feed inlet can be opened to easily receive corn ears delivered by the previous component. This design uses mechanical structural components, resulting in a simple structure and high reliability.

[0061] This embodiment also provides a harvesting system, which includes the aforementioned grain silo and therefore has all the beneficial effects of a grain silo, which will not be described in detail here.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
