Description

Technical Field

[0001] The present application relates to the technical field of corn harvester kernel recycling, and in particular to a kernel recycling hydraulic system for a corn harvester and a corn harvester. Background Art

[0002] When the corn harvester is working with the husker, it is inevitable that kernels will fall off. Therefore, kernel recycling and the kernel recycling bin are indispensable functions and structural components of the corn harvester.

[0003] Currently, there are mainly two ways to handle the kernel recycling of corn harvesters: First, after the kernel recycling bin is full, the kernels are conveyed out by a hydraulic-driven auger; Second, the kernels in the kernel bin are directly conveyed to the ear bin by mechanically driving the conveying auger in the kernel bin and the lifting and conveying auger outside the kernel bin, and then are discharged together with the unloading operation.

[0004] Currently, the above functions are all single functions. Users can only convey the kernel bin to the outside for manual reception after the kernel bin is full, or directly convey the kernels in the kernel bin to the ear bin. For users, there is no room for selection according to the operation situation, so there are inconveniences in the kernel recycling operation. Summary of the Utility Model

Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0023] Throughout the specification, when an element (such as a layer, region, or substrate) is described as "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, or there may be one or more other elements between them. In contrast, when an element is described as "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly above" another element, or "directly covering" another element, there may be no other elements between them.

[0024] 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.

[0025] 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.

[0031] In the following description, reference will be made to Figure 1 specifically describe the specific structures of the above components of the grain recovery hydraulic system for the corn harvester and the connection relationships of the above components.

[0032] As Figure 1 shown, in the embodiment, the hydraulic motor 1 can be drivingly connected to the first auger of the corn harvester. The hydraulic motor 1 is used to drive the first auger. The electromagnetic multi-way valve 3 can be connected to the hydraulic motor 1. The electromagnetic multi-way valve 3 can drive the hydraulic motor 1 to rotate forward or backward. The hydraulic pump 4 can be connected to the electromagnetic multi-way valve 3 through a pipeline for delivering hydraulic oil to the electromagnetic multi-way valve 3. The fuel tank 5 can be connected to the electromagnetic multi-way valve 3 and the hydraulic pump 4 through pipelines, and the fuel tank 5 is used to provide hydraulic oil. Preferably, when the hydraulic motor 1 rotates forward, the first auger can convey grains to the first side of the corn harvester. When the hydraulic motor 1 rotates backward, the first auger can convey grains to the second side of the corn harvester. The operator can optionally select one side of the first side and the second side of the corn harvester as the direct unloading side of the grains, and the grains on the other side are conveyed to the ear box of the corn harvester. With such a setting, by controlling the forward or backward rotation of the hydraulic motor 1, it is possible to switch between two different grain recovery functions.

[0033] Preferably, as Figure 1 shown, in the embodiment, the electromagnetic multi-way valve 3 can include a first connection port 303 and a second connection port 304. Among them, the first connection port 303 and the second connection port 304 can be the reversing ports A and B of the electromagnetic multi-way valve 3. The first connection port 303 and the second connection port 304 of the electromagnetic multi-way valve 3 can be respectively connected to both sides of the hydraulic motor 1 through pipelines to deliver hydraulic oil to the oil cavities on both sides of the hydraulic motor 1, thereby controlling the rotation direction of the hydraulic motor 1.

[0034] Preferably, as Figure 1 shown, in the embodiment, the electromagnetic multi-way valve 3 can further include an oil inlet 301 and an oil return port 302. Specifically, the oil inlet 301 can be the oil inlet P of the electromagnetic multi-way valve 3, and the oil return port 302 can be the oil return port T of the electromagnetic multi-way valve 3. Among them, the oil inlet 301 of the electromagnetic multi-way valve 3 can be connected to the hydraulic pump 4 through a pipeline. The oil return port 302 of the electromagnetic multi-way valve 3 can be connected to the fuel tank 5 through a pipeline.

[0035] Preferably, as Figure 1As shown, in the embodiment, a three-position four-way directional control valve 30 may be provided in the electromagnetic multi-way valve 3. Specifically, the three-position four-way directional control valve 30 may be communicated with the hydraulic pump 4. In addition, the three-position four-way directional control valve 30 may be communicated with the hydraulic motor 1, so as to supply oil to the hydraulic motor 1.

[0036] More preferably, as Figure 1 shown, in the embodiment, a two-position two-way valve 31 may also be provided in the electromagnetic multi-way valve 3. Specifically, the two-position two-way valve 31 may be communicated with the three-position four-way directional control valve 30. Among them, the combined operation of the two-position two-way valve 31 and the three-position four-way directional control valve 30 realizes the function of the electromagnetic multi-way valve 3 to control the forward and reverse rotation of the hydraulic motor 1. Such a setting can simplify the connection structure, facilitate installation and maintenance, and reduce costs.

[0037] Preferably, as Figure 1 shown, in the embodiment, a unloading valve 32 may also be provided in the electromagnetic multi-way valve 33. Preferably, the unloading valve 32 may be arranged in parallel with the two-position two-way valve 31, that is, both ends of the unloading valve 32 are communicated with both ends of the first two-position two-way valve 31. Such a setting can prevent the system from overloading and improve the stability and reliability of the system.

[0038] Preferably, as Figure 1 shown, in the embodiment, an oil suction filter 2 may also be provided between the hydraulic pump 4 and the fuel tank 5, that is, the hydraulic pump 4 may be connected to the oil suction filter 2 through a pipeline, and the oil suction filter 2 may be connected to the fuel tank 5. The oil suction filter 2 is used to provide clean hydraulic oil for the hydraulic pump 4.

[0039] In addition, according to the second aspect of the present invention, a corn harvester is provided. The corn harvester includes the grain recovery hydraulic system for the corn harvester as described above, and the corn harvester may be the corn harvester in the above embodiment.

[0040] Preferably, in the embodiment, when the hydraulic motor 1 rotates forward, the first auger transports the grains in the first direction, so as to be able to transport the grains to the first side of the corn harvester. When the hydraulic motor 1 rotates reversely, the first auger transports the grains in the second direction, and the second direction is the reverse direction of the first direction, so as to be able to transport the grains to the second side of the corn harvester.

[0041] More preferably, in the embodiment, the corn harvester may further include a second auger, which may be a lifting auger. The second auger may be disposed on the second side of the corn harvester. The kernels conveyed to the first side of the corn harvester may be directly discharged from the corn harvester. The kernels conveyed to the second side of the corn harvester may be conveyed by the second auger to the ear box of the corn harvester. It is not limited thereto, and it may also be that the second auger is disposed on the first side of the corn harvester. In this case, the kernels conveyed to the second side of the corn harvester are directly discharged, and the kernels conveyed to the first side of the corn harvester are conveyed by the second auger to the ear box.

[0042] During use, the hydraulic motor 1 is drivingly connected to the first auger of the corn harvester for driving the first auger. The electromagnetic multi-way valve 3 is connected to the hydraulic motor 1 to drive the hydraulic motor 1 to rotate forward or backward. When the hydraulic motor 1 rotates forward, the first auger can convey the kernels to the first side of the corn harvester for discharging. When the hydraulic motor 1 rotates backward, the first auger can convey the kernels to the second side of the corn harvester, and the second auger can convey them to the ear box. When the electromagnetic multi-way valve 3 is in the middle, the hydraulic motor 1 stops working. Thus, by controlling the forward or reverse rotation of the hydraulic motor 1, it is possible to switch between two different kernel recovery functions, so that the operator can make a choice according to the operating conditions.
