TECHNICAL FIELD

[0001] The utility model relates to a harvester technical field more specifically, relate to a kind of auxiliary support mechanism for increasing unloading grain agitator lifting range. BACKGROUND

[0002] The function of the unloading grain agitator system of combine harvester is to transport the crop fruits collected in the grain tank of combine harvester to the outside of the grain tank. In actual operation, due to the large difference in height between the field and the road surface, and the different grain receiving tools, the height of the unloading grain agitator discharge port is required to have a large lifting range.

[0003] The current lifting mode is that the support of the hydraulic cylinder body is connected with the fixed end of the elbow gear box, and the support of the hydraulic cylinder piston rod is connected with the unloading horizontal agitator cylinder. This connection mode often leads to either meeting the higher unloading height or meeting the lower unloading height, which limits the adaptability of the discharge port height. UTILITY MODEL CONTENT

[0004] In view of the problems in the prior art, the purpose of the utility model is to provide an auxiliary support mechanism which can improve the lifting height range of the discharge port without changing the telescopic drive.

[0005] To solve the above problems, the utility model adopts the following technical scheme. An auxiliary support mechanism for increasing the lifting range of the unloading grain agitator, comprising an elbow gear box, one end of the elbow gear box is a fixed end, the fixed end is movably connected with an unloading grain agitator discharge cylinder, the unloading grain agitator discharge cylinder is a discharge port away from the fixed end, further comprising:

[0006] A support member is installed on the fixed end.

[0007] A telescopic drive and a pull rod, the bottom end of the telescopic drive and the pull rod are movably installed on the support member.

[0008] A three-point rocker plate is provided with at least three triangularly arranged connection points, the three connection points are movably connected from bottom to top on the end of the pull rod away from the support member, the end of the telescopic drive away from the support member, and the unloading grain agitator discharge cylinder.

[0009] Preferably, the telescopic drive adopts a hydraulic cylinder, and the output end is connected with the three-point rocker plate.

[0010] Preferably, the connection points are round holes, and the round holes are movably connected with pins.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the process of telescopic drive telescoping, due to the restriction of the pull rod, the displacement of the connecting point on the three-point rocker plate and the discharge auger feeding cylinder active connection is greater than that of the connecting point connected with the telescopic drive, so that the lifting height range of the discharge outlet is increased without changing the telescopic drive, so that the combine harvester can adapt to different fields and different grain receiving tools during the discharge operation, improve the operation efficiency and reduce the operation cost.

[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] Reference Figs. 1-2 An auxiliary support mechanism for increasing the lifting range of the discharge auger, comprising an elbow gear box 1, one end of the elbow gear box 1 is a fixed end 11, the fixed end 11 is movably connected with a discharge auger feeding cylinder 2, the discharge auger feeding cylinder 2 is a discharge outlet 21 away from the fixed end 11, further comprising: a support 3 installed on the fixed end 11; a telescopic drive 4 and a pull rod 5, the bottom end of the telescopic drive 4 and the pull rod 5 is movably installed on the support 3; a three-point rocker plate 6, the three-point rocker plate 6 is provided with at least three triangularly arranged connecting points 61, the three connecting points 61 are movably connected in turn on the end of the pull rod 5 away from the support 3, the end of the telescopic drive 4 away from the support 3 and the discharge auger feeding cylinder 2.

[0019] It can be understood that the telescopic drive 4 is a component that can be driven to be telescopic, for example, can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, etc., but is not limited to this. The movable connection between the three-point rocker plate 6 and the unloading auger cylinder 2, the telescopic drive 4, and the pull rod 5, and the movable connection between the support 3 and the telescopic drive 4 and the pull rod 5 are connection modes that can swing at a certain angle between the two, for example, can be hinged, ball head connection, pin shaft and round hole matching connection, etc., but not limited to this. On the three-point rocker plate 6, in addition to the two connection points 61 movably connected with the pull rod 5 and the unloading auger cylinder 2, the connection points 61 movably connected with the telescopic drive 4 can be provided with multiple, and then the swinging range of the unloading auger cylinder 2 can be adjusted by connecting different connection points 61 through the telescopic drive 4.

[0020] In this way, during the telescopic process of the telescopic drive 4, due to the limitation of the pull rod 5, the displacement of the connection point 61 on the three-point rocker plate 6 movably connected with the unloading auger cylinder 2 is greater than that of the connection point 61 connected with the telescopic drive 4, so that the function of increasing the lifting height range of the unloading auger cylinder 2 is realized without changing the telescopic drive 4. When the telescopic drive 4 is extended, the connection point 61 of the three-point rocker plate 6 connected with the unloading auger cylinder 2 is raised upward, so that the unloading auger cylinder 2 is raised to increase the height of the discharge port 21; when the telescopic drive 4 is retracted, the connection point 61 of the three-point rocker plate 6 connected with the unloading auger cylinder 2 is lowered, so that the unloading auger cylinder 2 is lowered to decrease the height of the discharge port 21.

[0021] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
