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.

[0020] 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.

[0021] 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.

[0022] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0023] 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.

[0024] 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.

[0028] like Figures 1-7 As shown, this embodiment first provides a quick adjustment device for the winding length of a round baler, which mainly includes a side plate 1, a first spring 2, a wire cutter assembly 3, a hook welding assembly 4, an adjusting wrench assembly 5, a rubber roller assembly 6, a connecting plate 8, and a friction shaft 9.

[0029] The rubber roller assembly 6 is mounted on the front of the side plate 1 via a rubber roller bearing at its end; and the rotating shaft of the rubber roller assembly 6 passes through the side plate 1, with a rubber roller gear 11 provided at its end on the back of the side plate 1.

[0030] The rubber roller gear 11 meshes with the intermediate gear 12. After speed ratio calculation, the intermediate gear 12 is converted from a large gear to a small gear. The small gear meshes with the friction shaft gear 13. The rotating shaft of the friction shaft gear 13 is the friction shaft 9, which is rotatably mounted on the side plate 1.

[0031] The wire cutting blade assembly 3 is fastened to the outside of the rubber roller bearing via a lifting lug and can rotate around the rubber roller bearing; a mounting shaft is provided on the wire cutting blade assembly 3. An arc-shaped hole is provided on the side plate 1, through which the mounting shaft passes and can move within the arc-shaped hole.

[0032] One end of the hook weld 4 is a connecting part, which is rotatably connected to the mounting shaft of the wire cutter assembly 3; the other end is a hook part, which is hooked onto the friction shaft 9; the rotation of the friction shaft 9 can drive the hook weld 4 and the wire cutter assembly 3 to rotate around the rubber roller bearing.

[0033] The area where the friction shaft 9 contacts the hook weld 4 is knurled 901 to increase friction. When the friction shaft 9 rotates, it can drive the hook weld 4 upward through friction.

[0034] One end of the first spring 2 is fixed, and the other end is connected to one end of the connecting plate 8; the other end of the connecting plate 8 is connected to the mounting shaft of the wire cutter assembly 3. The first spring 2 can exert a downward pulling force on the wire cutter assembly 3 through the connecting plate 8.

[0035] The adjustment wrench assembly 5 is rotatably mounted on the side plate 1 and can remain relatively fixed to the side plate 1 in different positions; the end face of the adjustment wrench assembly 5 abuts against the hook part of the hook weld 4 to adjust the contact position between the hook weld 4 and the friction shaft 9 in the natural state.

[0036] The natural state refers to the state when there is no power input to the rubber roller assembly 6.

[0037] More specifically, the structure and adjustment method of the wrench assembly 5 are as follows: Figure 8 and Figure 9 As shown: The edge of the side plate 1 is provided with several scale grooves to form several gear positions; The adjusting wrench assembly 5 includes a "U"-shaped wrench weld 52, one arm of which is mounted on the back of the side plate 1 via a rotating sleeve 51 and a fixing bolt 57, allowing it to rotate relative to the side plate 1. The other arm of the wrench weld 52 extends to the front of the side plate 1 and forms an end face for abutting against the hook of the hook weld 4; The connecting part between the two arms of the wrench weld 52 is provided with a long groove and a short groove, and the short groove can be engaged with the stop of the side plate 1.

[0038] The two arms of the wrench weld 52 are connected by a long bolt 53 and a nut 56. A second spring 55 is fitted onto the long bolt 53. One end of the second spring 55 abuts against one arm of the wrench weld 52 forming the end face, and the other end abuts against the front of the side plate 1. A flat washer 54 is provided between the second spring 55 and the side plate 1.

[0039] In use, first move the wrench assembly 52 from position A to position B on the right, so that the scale groove of the side plate 1 moves into the long groove of the adjusting wrench assembly 5. At this time, the adjusting wrench assembly 5 can rotate up and down along the arc groove of the side plate 1 at position B. When it moves to the desired position, move the wrench assembly 52 to the left to position C, so that the short groove of the wrench assembly 52 is locked in the middle of the scale groove of the side plate 1. This allows the contact position of the hook assembly 4 and the friction shaft 9 in their natural state to be adjusted, thereby adjusting the length of the wire mesh.

[0040] Preferably, a limiting block 7 is also provided on the side plate 1, which is used to limit the extreme position when the hook welding 4 falls back.

[0041] During the net wrapping process, the rubber roller assembly 6 rotates, and through the transmission of the rubber roller gear 11, intermediate gear 12, and friction shaft gear 13, it drives the friction shaft 9 to rotate. Simultaneously, the rotation of the friction shaft 9 causes the hook weld 4 to move upwards through friction. When the hook weld 4 reaches its uppermost position, the downward force acting on it exceeds the upward frictional force provided by the friction shaft 9. Under the action of the first spring 2 and connecting plate 8, the net cutter assembly 3 rapidly rotates and falls along the center of the rubber roller bearing, cutting the net and completing the wrapping process. The adjusting wrench assembly 5 adjusts the contact distance between the hook weld 4 and the friction shaft 9 by rotating up and down, thereby controlling the length of the wrapped net. The limiting block 7 restricts the falling position of the hook weld 4.

[0042] This embodiment also provides a round baler, including the aforementioned quick adjustment device for the winding length of the round baler.

[0043] 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.
