Description

Technical Field

[0001] This application relates to the field of rice and wheat crop conveying structures for harvesters, and in particular to a rice and wheat crop conveying assembly and a harvester. Background Technology

[0002] In a semi-feed rice combine harvester, the conveyor assembly is connected to the header to transport the harvested crop grains to the thresher. During harvesting, the height of the header is not constant. As the crop height and terrain change, the operator needs to adjust the header height in a timely manner (especially when harvesting to the end of the field, the header needs to be raised in time to reduce losses).

[0003] In existing harvesters, the conveyor assembly includes a connecting frame (connected to the header), a supply cover, and a feed plate, all three being rigidly connected by screws. The supply cover forms an integral structure (e.g., Figure 1 (As shown). Thus, when the height of the header changes, it will cause the supply cover and the feed plate to rise and fall, which can easily lead to deformation and twisting of the supply cover and the feed plate, thereby affecting the transport of rice and wheat crops, causing blockages and grain loss. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a rice and wheat crop conveying assembly and a harvester to solve the problem that in existing harvesters, the supply cover and feed plate are prone to deformation and twisting as the header rises and falls, which affects the conveying of rice and wheat crops.

[0025] The following detailed description is provided to help the reader obtain a complete understanding of the methods, devices and / or systems described herein. However, various changes, modifications and equivalents can be apparent to those skilled in the art after understanding the disclosure of the present application. For example, the order of the operations described herein is merely an example, and is not limited to the order set forth herein, and changes can be made that will be apparent to those skilled in the art after understanding the disclosure of the present application, except for the operations that must occur in a specific order. In addition, the description of features known in the art can be omitted in order to improve clarity and brevity.

[0026] The features described herein can 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 show some of the many ways in which the methods, devices and / or systems described herein can be implemented, which will be apparent to those skilled in the art after understanding the disclosure of the present application.

[0027] Throughout the specification, when an element (such as a layer, region or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, "on top of" another element, or "covering" another element, it can be directly on, connected to, coupled to, adjacent to, on top of, or covering the other element, or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on", "directly connected to", "directly coupled to", "directly adjacent to", "directly on top of", or "directly covering" another element, there are no other elements interposed therebetween.

[0028] As used herein, the term "and / or" includes any one of the listed items and any combination of two or more of the listed items.

[0029] Although terms such as "first" and "second" and "third" can be used herein to describe various components, assemblies, regions, layers or sections, these components, assemblies, regions, layers or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, assembly, region, layer or section from another component, assembly, region, layer or section. Thus, a component, assembly, region, layer or section referred to as a first component, assembly, region, layer or section in one example described herein can also be referred to as a second component, assembly, region, layer or section in another example without departing from the teachings of the examples.

[0030] For ease of description, spatial relationship terms, such as "on", "upper", "beneath", and "lower", can be used herein to describe the relationship of one element to another element as illustrated in the figures. Such spatial relationship terms can be intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures.

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.

[0034] According to a first aspect of this utility model, a rice and wheat crop conveying assembly is provided, such as... Figure 2 As shown, the rice and wheat crop conveying assembly in this embodiment includes a connecting frame 1, a supply cover 2, and a feeding plate 4. Furthermore, the supply cover 2 in this embodiment is formed as a split structure to prevent the feeding plate 4 and the supply cover 2 from rising and falling synchronously with the header, thereby effectively extending the service life of the conveying assembly. The specific connection and positional relationships of the various components of the rice and wheat crop conveying assembly according to this utility model will be described in detail below.

[0035] In this embodiment, as Figure 2 As shown, the connecting frame 1, the supply cover 2, and the feeding plate 4 are sequentially connected to form a conveying assembly. The end of the connecting frame 1 away from the supply cover 2 is connected to the header, meaning the connecting frame 1 can be synchronously raised and lowered by the header. The end of the feeding plate 4 away from the supply cover 2 extends to the junction of this conveying assembly and the thresher, facilitating the transfer of harvested crop grains to the thresher. To ensure accurate description of the various structures below, the connection direction of these three components is defined as the first direction (i.e., Figure 2 (The direction indicated by the middle arrow), further, the first direction is perpendicular to the lifting direction of the cutting table.

[0036] It should be noted that the specific structures of the connecting frame 1 and the feeding plate 4 are not fixed and can be manufactured according to existing conveying assemblies. In addition, the connection method between the connecting frame 1 and the header is also not fixed. For example, welding or screw connection can be used, as long as the stability of the overall structure of the conveying assembly and the stability of the connection between the conveying assembly and other components in the harvester can be guaranteed.

[0037] Further, in the present embodiment, as shown in Figure 2 the split supply cover 2 includes a front plate 21 and a rear plate 22, both of which are rotationally connected. That is, the split supply cover 2 actually refers to the fact that the front plate 21 and the rear plate 22 can rotate relative to each other. Furthermore, the front plate 21 of the supply cover 2 is connected to the connecting frame 1, and the rear plate 22 of the supply cover 2 is connected to the feeding rubber plate 4, that is, the connecting frame 1, the front plate 21, the rear plate 22, and the feeding rubber plate 4 are sequentially connected in the first direction. In the present embodiment, the supply cover 2 is connected to the connecting frame 1 and the feeding rubber plate 4 by screwing, so that the stability of the overall structure of the conveying assembly can be ensured, and the supply cover 2 can be easily disassembled and repaired; however, the supply cover 2 can also be connected to the connecting frame 1 and the feeding rubber plate 4 by other connection methods such as riveting, etc.

[0038] Specifically, as shown in Figure 3 the front plate 21 and the rear plate 22 are rotationally connected by a rotating mechanism, and the extension direction of the rotating shaft of the rotating mechanism is formed as the second direction, which is perpendicular to the first direction and perpendicular to the lifting direction of the cutting platform. More specifically, the rotating mechanism in the present embodiment includes two rotating assemblies 3, and the two rotating assemblies 3 are arranged in the second direction, so that the stability of the front plate 21 when rotating relative to the rear plate 22 can be ensured, and the stability of the overall structure of the conveying assembly can be improved. The number and specific arrangement position of the rotating assemblies 3 are not fixed, as long as the above technical effects can be achieved.

[0039] The rotating assembly 3 includes a rotating shaft 33, a first connecting plate 31, and a second connecting plate 32, and the first connecting plate 31 and the second connecting plate 32 are respectively rotationally connected to the rotating shaft 33. As shown in Figure 3 the first connecting plate 31 is formed in a cuboid plate structure; in the first direction, the first end of the first connecting plate 31 (close to the connecting frame 1) is connected to the front plate 21, and the second end of the first connecting plate 31 (close to the feeding rubber plate 4) is formed with two first protrusions 311, both of which are formed with through holes, and the through holes are provided with first bearings corresponding to the rotating shaft 33. The first connecting plate 31 can be sleeved on the outer side of the rotating shaft 33 (that is, the first connecting plate 31 is fixedly connected to the outer ring of the first bearing, and the rotating shaft 33 is fixedly connected to the inner ring of the first bearing) through the first bearing, so that the rotating connection between the first connecting plate 31 and the rotating shaft 33 can be achieved.

[0040] Similarly, the second connecting plate 32 is also formed as a cuboid plate structure; along the first direction, a second protrusion 321 is formed at the first end of the second connecting plate 32, the second protrusion 321 is also formed with a through hole, and a corresponding second bearing is arranged in the through hole, the second connecting plate 32 can be sleeved on the outer side of the rotating shaft 33 through the second bearing, so that the rotating connection between the second connecting plate 32 and the rotating shaft 33 can be realized; the second end of the second connecting plate 32 is connected with the rear plate 22. In order to ensure the stability of the overall structure of the rotating assembly 3, after the first connecting plate 31 and the second connecting plate 32 are connected with the rotating shaft 33 correspondingly, a concave-convex matched structure is formed.

[0041] In the embodiment, the first connecting plate 31 and the second connecting plate 32 are respectively screwed with the front plate 21 and the rear plate 22, so as to ensure the stability of the overall structure of the feeding cover 2, but the connection mode is not limited thereto, and for example, welding, pin connection and the like can also be adopted. In addition, preferably, along the first direction, the width (i.e. ​ L) of the first connecting plate 31 or the second connecting plate 32 is 5-10mm, so as to avoid interference and the like during rotation, thereby ensuring the smoothness of the rotation of the front plate 21.

[0042] According to the rice and wheat crop conveying assembly of the utility model, the feeding cover 2 is provided as a split structure, that is, the feeding cover 2 comprises the rotatingly connected front plate 21 and rear plate 22, and the connecting frame 1 and the feeding rubber plate 4 are connected with the front plate 21 and the rear plate 22 respectively. Thus, when the cutting platform is lifted, only the connecting frame 1 and the front plate 21 of the feeding cover 2 are lifted synchronously, and the rear plate 22 of the feeding cover 2 and the feeding rubber plate 4 can remain in a stable state. Compared with the feeding cover 2 (and the conveying assembly without relative motion) of the prior art which is of an integral structure, the utility model can effectively avoid the deformation and distortion of the feeding cover 2 and the feeding rubber plate 4, so as to not affect the conveying of the crops, and effectively ensure the smoothness and conveying efficiency of the conveying of the crops.

[0043] According to the second aspect of the utility model, a harvester is provided, and the harvester is provided with the above-mentioned rice and wheat crop conveying assembly.
