The multi-way valve control structure includes a connecting rod, a first operating component, and a second operating component. The sidewall of the connecting rod is composed of multiple surfaces. The first operating component includes a first spacer, a first connecting part, and a first operating part. The inner sidewalls of the first spacer and the first connecting part are each composed of multiple surfaces adapted to the connecting rod. The second operating component includes a second spacer, a second connecting part, and a second operating part.

Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment technology, and in particular to a multi-way valve control structure for tractors and tractors. Background Technology

[0002] The multi-way valve control structure is an essential component in tractors, capable of controlling the movement of multiple actuators.

[0003] Combination Figure 1 and Figure 2 As shown, the traditional multi-way valve operating structure mainly includes a first operating lever 1', a second operating lever 2', a base 3', a connecting shaft 4', a first sleeve 5', a second sleeve 6', a washer 7', and a nut 8'; wherein the connecting shaft 4' extends from the base 3' and is a round shaft; the first operating lever 1' is sleeved on the connecting shaft 4' at a first preset position via the first sleeve 5', and the second operating lever 2' is sleeved on the connecting shaft 4' at a second preset position via the second sleeve 6'; the washer 7' is sleeved on the connecting shaft 4' and is located at a position where the second operating lever 2' is away from the first operating lever 1'; the nut 8' locks the first operating lever 1' and the second operating lever 2' to the connecting shaft 4'.

[0004] Using the existing structure described above, when the first operating lever 1' is pulled, the first operating lever 1' will rotate around the first sleeve 5'. However, when the first operating lever 1' rotates around the first sleeve 5', since the first operating lever 1' is in contact with the second sleeve 6', and since the first sleeve 5' is sleeved on the connecting shaft 4' with a circular cross-section, it will cause the second sleeve 6' to rotate slightly on the connecting shaft 4'. When the second sleeve 6' rotates on the connecting shaft 4', it will cause the second operating lever 2' to rotate. That is to say, when the first operating lever 1' is pulled, the second operating lever 2' will be activated. Similarly, when the second operating lever 2' is pulled, the first operating lever 1' will be activated. As a result, since the first operating lever 1' and the second operating lever 2' control the lifting and lowering of the machine respectively, the lifting effect of the hoist on the machine will be affected.

[0005] Therefore, there is an urgent need for a multi-way valve control structure for tractors and tractors in general, in order to solve the technical problems existing in the current technology to a certain extent. Utility Model Content

Both the second spacer sleeve and the second connecting sleeve are sleeved on the connecting rod, and the second spacer sleeve is close to the side of the first operating part that is away from the first spacer sleeve. The second operating part is sleeved on the second connecting sleeve and can rotate around the second connecting sleeve; The inner walls of the second spacer sleeve and the second connecting sleeve are respectively composed of a fifth arc-shaped surface adapted to the first arc-shaped surface, a fifth straight-cut surface adapted to the first straight-cut surface, a sixth arc-shaped surface adapted to the second arc-shaped surface, and a sixth straight-cut surface adapted to the second straight-cut surface.

[0011] In the above technical solution, the diameter of the first spacer sleeve is larger than the diameter of the first connecting sleeve, so that the first operating part is separated from the base by the first spacer sleeve; The diameter of the second spacer sleeve is larger than the diameter of the second connecting sleeve, so that the second operating part is spaced apart from the side of the first operating part away from the first spacer sleeve by the second spacer sleeve.

[0012] In the above technical solution, the first operating part further includes a first rotating handle and a first operating handle connected to the first rotating handle at a first preset angle; the first rotating handle is sleeved on the first connecting sleeve.

[0015] In the above technical solution, the multi-way valve operating structure further includes a third washer; The third washer is fitted onto the connecting rod and is located between the first washer and the second rotating handle.

[0016] This application also provides a tractor, including the multi-way valve control structure of the tractor described above.

[0017] Compared with the prior art, this application has the following beneficial effects: This application provides a multi-way valve control structure for a tractor, disposed on a base, the multi-way valve control structure for the tractor comprising: A connecting rod is disposed on the base, and the sidewall of the connecting rod is composed of multiple surfaces; The first operating component includes a first sleeve portion and a first operating portion; the first sleeve portion has a first spacer portion sleeved on the connecting rod and a first connecting portion connected to the first spacer portion and sleeved on the connecting rod; the first operating portion is sleeved on the first connecting portion and is rotatable around the first connecting portion; the inner sidewalls of the first spacer portion and the first connecting portion are respectively composed of a plurality of surfaces adapted to the connecting rod.

The second operating portion is sleeved on the second connecting portion and is rotatable around the second connecting portion. The inner sidewalls of the second spacer portion and the second connecting portion are respectively composed of a plurality of surfaces adapted to the connecting rod.

[0018] In summary, since a second spacer is provided between the second operating part and the first operating part, meaning that the second spacer is in contact with both the first and second operating parts, if the existing structure is used, when the first operating part rotates around the connecting rod, since the cross-section of the connecting rod is circular, the second spacer will also rotate around the connecting rod (or have a slight rotational motion). However, when the second spacer rotates on the connecting rod, since the second spacer is connected to the second connecting part, the second connecting part will rotate on the connecting rod. Therefore, when the second connecting part rotates, it will drive the second operating part to rotate. In other words, the rotation of the first operating part will be linked to the rotation of the second operating part. However, in this application, since the first spacer, the first connecting part, the second spacer, the second connecting part and the connecting rod are respectively configured to limit each other, it means that when the first operating part rotates around the connecting rod, it will not cause the second spacer to rotate on the connecting rod, nor will it cause the second connecting part to rotate on the connecting rod, and thus it will not cause the second operating part to rotate. In other words, there will be no linkage problem between the first operating part and the second operating part, thus overcoming the problem of linkage between the first operating part and the second operating part that occurs when using the structure in the prior art.

[0019] This application also provides a tractor including the aforementioned multi-way valve control structure for tractors. Therefore, all the beneficial effects of the aforementioned multi-way valve control structure for tractors are not detailed here. Attached Figure Description

Detailed Implementation

[0023] The following detailed embodiments are provided to aid the reader in gaining 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 upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order presented herein; rather, changes that will be apparent upon understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity. The features described herein may be implemented in different 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, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application. Throughout this 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. Conversely, 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. As used herein, the term "and / or" includes any one of the relevant items listed and any combination of any two or more of them. Although terms such as "first," "second," and "third" may be used herein to describe individual components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. More precisely, 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 such in the examples may also be referred to as the second component, assembly, region, layer, or part. For ease of description, spatial relational terms such as “above,” “upper,” “below,” and “lower” may be used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relational terms are intended to include not only the orientation depicted in the drawings but also the different orientations of the device in 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" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., oscillating 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly. The terminology used herein is for 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. Variations in the shapes shown in the figures may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the figures but include changes in shape that occur during manufacturing. The features of the examples described herein may be combined in various ways that will be apparent upon understanding the disclosure of this application. 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.

[0024] Example 1 To address the technical problem of linkage between the first and second operating levers in existing multi-way valve control structures during practical use, this application provides a multi-way valve control structure for tractors, which is described below in conjunction with... Figures 3-8 The structure is described in detail.

[0025] The tractor's multi-way valve control structure is located on the base 4 of the tractor's cab, combined with... Figure 7 And refer to Figure 8 As shown, the multi-way valve control structure of the tractor includes a connecting rod 1, which is disposed on the base 4. Optionally, the connecting rod 1 is perpendicular to the base 4 and extends from the base 4. Furthermore, the sidewall of the connecting rod 1 is composed of multiple surfaces, that is, the connecting rod 1 is not a circular shaft structure, and its cross-section is not circular but polygonal.

[0026] Combination Figures 3-8 As shown, the multi-way valve control structure of the tractor also includes a first operating component 2, which includes a first sleeve portion 201 and a first operating portion 202; wherein, the first sleeve portion 201 has a first spacing portion 203 and a first connecting portion 204, both the first spacing portion 203 and the first connecting portion 204 are sleeved on the connecting rod 1 and the first spacing portion 203 is located at one end of the connecting rod 1 near the base 4.

[0027] The first operating part 202 is sleeved on the first connecting part 204 and can rotate around the first connecting part 204. Since the first spacing part 203 is close to the base 4, the base 4 is separated from the first operating part 202. This arrangement can prevent the first operating part 202 from wearing down the base 4 during rotation, thereby ensuring the service life of the base 4.

[0028] The inner walls of the first sleeve portion 201 and the first connecting portion 204 are each composed of multiple surfaces adapted to the connecting rod 1. That is, the cross-sections of the inner walls of the first sleeve portion 201 and the first connecting portion 204 are not circular, but polygonal. Since the inner walls of the first spacer portion 203 and the first connecting portion 204 are each composed of multiple surfaces adapted to the connecting rod 1, the first spacer portion 203 and the first connecting portion 204 will not rotate around the connecting rod 1. In other words, the connecting rod 1 and the first spacer portion 203 and the first connecting portion 204 form a mutually limiting structure.

[0029] Still combined Figures 3-8 As shown, the multi-way valve control structure of the tractor also includes a second operating component 3, which includes a second sleeve portion 301 and a second operating portion 302. The second sleeve includes a second spacer portion 303 and a second connecting portion 304 connected to the second spacer portion 303. Specifically, the second sleeve portion 301 and the second connecting portion 304 are both sleeved on the connecting rod 1, and the two sides of the second spacer portion 303 are the first connecting portion 204 and the second connecting portion 304, respectively.

[0030] The second operating part 302 is sleeved on the second connecting part 304 and can rotate around the second connecting part 304. Since the first connecting part 204 and the second connecting part 304 are on opposite sides of the second spacing part 303, and the first operating part 202 is sleeved on the first connecting part 204 and the second operating part 302 is sleeved on the second connecting part 304, the second spacing part 303 can separate the first operating part 202 and the second operating part 302.

[0031] The inner walls of the second sleeve portion 301 and the second connecting portion 304 are each composed of multiple surfaces adapted to the connecting rod 1. That is, the cross-sections of the inner walls of the second sleeve portion 301 and the second connecting portion 304 are not circular, but polygonal. Since the inner walls of the second spacer portion 303 and the second connecting portion 304 are each composed of multiple surfaces adapted to the connecting rod 1, the second spacer portion 303 and the second connecting portion 304 will not rotate around the connecting rod 1. In other words, the connecting rod 1 and the second spacer portion 303 and the second connecting portion 304 form a mutually limiting structure.

[0032] In summary, since a second spacer 303 is provided between the second operating part 302 and the first operating part 202, meaning that the second spacer 303 is in contact with both the first operating part 202 and the second operating part 302, if the existing structure is used, when the first operating part rotates around the connecting rod, since the cross-section of the connecting rod is circular, the second spacer will also rotate around the connecting rod (or have a slight rotational movement). However, when the second spacer rotates on the connecting rod, since the second spacer is connected to the second connecting part, the second connecting part will rotate on the connecting rod. Therefore, when the second connecting part rotates, it will drive the second operating part to rotate. That is, the rotation of the first operating part will be linked to the rotation of the second operating part (when the second operating part rotates around the connecting rod, it will also be linked to the rotation of the first operating part around the connecting rod). However, in this application, since the first spacer 203, the first connecting part 204, the second spacer 303, the second connecting part 304 and the connecting rod 1 respectively form a mutually limiting structure, that is to say, when the first operating part 202 rotates around the connecting rod 1, it will not drive the second spacer 303 to rotate on the connecting rod 1, nor will it drive the second connecting part 304 to rotate on the connecting rod 1, and thus will not drive the second operating part 302 to rotate. In other words, there will be no linkage problem between the first operating part 202 and the second operating part 302, thus overcoming the problem of linkage between the first operating part 202 and the second operating part 302 that occurs when using the structure in the prior art.

[0033] In this embodiment, further, combined with Figure 8 As shown, the connecting rod 1 is perpendicular to the first surface 401 of the base 4; the side wall of the connecting rod 1 is composed of four connecting surfaces, namely the first arc surface 101, the first straight tangent surface 102, the second arc surface 103 and the second straight tangent surface 104.

[0034] Specifically, the first arc-shaped surface 101, the first straight tangent surface 102, the second arc-shaped surface 103, and the second straight tangent surface 104 are connected in sequence.

[0035] Furthermore, the first arc-shaped surface 101 and the second arc-shaped surface 103 are arranged symmetrically about the axis of the connecting shaft, and the first straight tangent surface 102 and the second straight tangent surface are arranged symmetrically about the axis of the connecting shaft; that is, the cross-sections of the first arc-shaped surface 101, the first straight tangent surface 102, the second arc-shaped surface 103 and the second straight tangent surface 104 are oval.

[0036] It is worth noting that: Figure 8 The diagram only shows one configuration of the side of the connecting rod 1, but this application is not limited to the above four connecting surfaces, and may also have five, six, seven, etc.

[0037] In this embodiment, further, combined with Figure 3 and Figure 4and refer to Figure 7 and Figure 8 As shown, the first spacing part 203 is the first spacing sleeve 205, and the first connecting part 204 is the first connecting sleeve 206. The first spacing sleeve 205 is connected to the first connecting sleeve 206, and both the first spacing sleeve 205 and the first connecting sleeve 206 are sleeved on the connecting rod 1, with the first spacing sleeve 205 close to the base 4.

[0038] The first operating part 202 is sleeved on the first connecting sleeve 206 and can rotate around the first connecting sleeve 206. The outer side wall of the first connecting sleeve 206 has a circular cross-section, and the inner side wall of the first operating part 202 is adapted to the outer side wall of the first connecting sleeve 206 and also has a circular cross-section, thereby enabling the first operating part 202 to rotate around the first connecting sleeve 206.

[0039] The inner walls of the first spacer sleeve 205 and the first connecting sleeve 206 are respectively composed of a third arcuate surface 209 adapted to the first arcuate surface 101, a third straight tangent surface adapted to the first straight tangent surface 102, a fourth arcuate surface 211 adapted to the second arcuate surface 103, and a fourth straight tangent surface 212 adapted to the second straight tangent surface. This arrangement creates a mutually limiting structure between the first spacer sleeve 205 and the connecting rod 1, and also between the first connecting sleeve 206 and the connecting rod 1. That is, the first spacer sleeve 205 will not rotate on the connecting rod 1, and similarly, the first connecting sleeve 206 will not rotate on the connecting rod 1.

[0040] In this embodiment, further, combined with Figure 5 and Figure 6 As shown, the second spacing portion 303 is the second spacing sleeve 305, and the second connecting portion 304 is the second connecting sleeve 306. The second spacing sleeve 305 is connected to the second connecting sleeve 306, and both the second spacing sleeve 305 and the second connecting sleeve 306 are sleeved on the connecting rod 1, with the second spacing sleeve 305 located on the side of the first operating portion 202 away from the first spacing sleeve 205.

[0041] The second operating part 302 is sleeved on the second connecting sleeve 306 and can rotate around the second connecting sleeve 306. The outer wall of the second connecting sleeve 306 has a circular cross-section, and the inner wall of the second operating part 302 is adapted to the outer wall of the second connecting sleeve 306, and also has a circular cross-section, thereby enabling the second operating part 302 to rotate around the second connecting sleeve 306.

[0042] The inner walls of the second spacer sleeve 305 and the second connecting sleeve 306 are respectively composed of a fifth arcuate surface 307 adapted to the first arcuate surface 101, a fifth straight tangent surface 308 adapted to the first straight tangent surface 102, a sixth arcuate surface 309 adapted to the second arcuate surface 103, and a sixth straight tangent surface 310 adapted to the second straight tangent surface. This arrangement creates a mutually limiting structure between the second spacer sleeve 305 and the connecting rod 1, and also between the second connecting sleeve 306 and the connecting rod 1. That is, the second spacer sleeve 305 will not rotate on the connecting rod 1. In other words, when the first operating part 202 rotates on the first connecting sleeve 206, it will not cause the second spacer sleeve 305 to rotate on the connecting rod 1. Consequently, the second connecting sleeve 306 will not rotate on the connecting rod 1. Therefore, when the first operating part 202 rotates, it will not trigger the second operating part 302 to rotate. Similarly, when the second operating part 302 rotates, it will not cause the second spacer sleeve 305 to rotate on the connecting rod 1, and therefore will not cause the first operating part 202 to rotate on the first connecting sleeve 206.

[0043] In this embodiment, the diameter of the first spacer sleeve 205 is larger than the diameter of the first connecting sleeve 206. That is, the cross-section of the first sleeve portion 201 formed by the first spacer sleeve 205 and the first connecting sleeve 206 is T-shaped, so that the first operating portion 202 is separated from the base 4 by the first spacer sleeve 205.

[0044] Similarly, the diameter of the second spacer sleeve 305 is larger than the diameter of the second connecting sleeve 306. That is, the cross-section of the second sleeve portion 301 formed by the second spacer sleeve 305 and the second connecting sleeve 306 is T-shaped, so that the second operating portion 302 is separated from the first operating portion 202 on the side away from the first spacer sleeve 205 by the second spacer sleeve 305.

[0045] The first spacer sleeve 205, the first connecting sleeve 206, the second spacer sleeve 305, and the second connecting sleeve 306 are all made of nylon.

[0046] In this embodiment, further, combined with Figure 3 , Figure 5 As shown in Figure 7, the first operating part 202 includes a first rotating handle 207 and a first operating handle 208 connected to the first rotating handle 207 at a first preset angle; the first rotating handle 207 is sleeved on the first connecting sleeve 206; the first preset angle is preferably 100°.

[0047] In addition, the second operating part 302 includes a second rotating handle 311 and a second operating handle 312 connected to the second rotating handle 311 at a second preset angle; the second rotating handle 311 is sleeved on the second connecting sleeve 306, and the first preset angle is preferably 100°.

[0048] Specifically, the first operating handle 208 includes a first segment 213, a second segment 214, and a third segment 215 connected in sequence; the first segment 213 is connected to the first rotating handle 207, the first segment 213 and the second segment 214 are connected at a 100° angle, and the second segment 214 and the third segment 215 are connected at a 120° angle. Furthermore, the second operating handle 312 includes a fourth segment 313, a fifth segment 314, and a sixth segment 315 connected in sequence; the fourth segment 313 is connected to the second rotating handle 311, the fourth segment 313 and the fifth segment 314 are connected at a 100° angle, and the fifth segment 314 and the sixth segment 315 are connected at a 120° angle.
