[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0039] The following description, with reference to the accompanying drawings, describes the ear-picking adjustment device and harvester according to the present invention.

[0040] like Figure 1 As shown, in this embodiment, a harvesting adjustment device is proposed, which includes a harvesting plate frame, a harvesting assembly, a transmission assembly, and a rotary drive assembly. The harvesting assembly includes two harvesting plates 3 spaced apart along the width direction, and a first rotating shaft 1 and a second rotating shaft 2 rotatably mounted on the harvesting plate frame. One harvesting plate 3 is arranged on the first rotating shaft 1, and the other harvesting plate 3 is arranged on the second rotating shaft 2, forming a harvesting space extending along the length direction between the two harvesting plates 3. The rotary drive assembly is used to drive the first rotating shaft 1 and the second rotating shaft 2 to rotate around their own axes, so as to drive the two harvesting plates 3 to swing in opposite directions. The rotation directions of the first rotating shaft 1 and the second rotating shaft 2 are opposite. The transmission assembly is drivenly connected to the rotary drive assembly. The transmission assembly includes a transmission rod group and a connecting rod group provided on the transmission rod group. The connecting rod group includes a connecting rod component that is drivenly connected to both the first rotating shaft 1 and the second rotating shaft 2, so as to achieve efficient transmission and cooperation. In this embodiment, the ear-picking adjustment device drives the first rotating shaft 1 and the second rotating shaft 2 to rotate around their own axes via a rotary drive assembly. This causes the two ear-picking plates 3 to swing in opposite directions. For example, one ear-picking plate 3 rotates counterclockwise, and the other ear-picking plate 3 rotates clockwise. This causes the two ear-picking plates 3 to move closer to or further apart, thereby adjusting the inner diameter of the harvesting space to accommodate the harvesting requirements of corn stalks of different sizes. This solves the technical problem of low harvesting efficiency and yield of fixed ear-picking plates 3 in the prior art. The length direction is... Figure 1 The front-to-back direction is shown in the figure, and the width direction is shown in the figure.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the transmission rod assembly includes a first transmission member 5 and a second transmission member 6. The first transmission member 5 and the second transmission member 6 are arranged in parallel at intervals to ensure efficient transmission and coordination with the rotary drive assembly. The connecting rod component includes a first connecting member 7 and a second connecting member 8 respectively disposed on the first transmission member 5 and the second transmission member 6. The first end of the first connecting member 7 is hinged to the first transmission member 5, and the second end is fixedly connected to the first rotating shaft 1. The first end of the second connecting member 8 is hinged to the second transmission member 6, and the second end is fixedly connected to the second rotating shaft 2. By adding the first transmission member 5 to drive the first connecting member 7 and by adding the second transmission member 6 to drive the second connecting member 8, the space occupied by the first connecting member 7 and the second connecting member 8 can be reduced while ensuring efficient transmission, leaving sufficient space for other structures.

[0042] Furthermore, both the number of connecting rod groups and the number of ear-picking components are multiple and connected one-to-one. By rotating the drive component, the transmission rod group can be driven to move, thereby driving multiple connecting rod groups and the rotating shaft to move together, thus realizing the synchronous adjustment of multiple ear-picking components and improving the convenience of ear-picking plate adjustment.

[0043] In this embodiment, the connecting rod assembly includes a first support member 41 and a second support member 42 respectively disposed on the first transmission member 5 and the second transmission member 6. The two ends of the first support member 41 are hinged to the first transmission member 5 and the second rotating shaft 2, respectively, and the two ends of the second support member 42 are hinged to the second transmission member 6 and the first rotating shaft 1, respectively. The first support member 41 is arranged parallel to the first connecting member 7, and the second support member 42 is arranged parallel to the second connecting member 8. By adding the first support member 41 and the second support member 42, the movement range of the first transmission member 5 and the second transmission member 6 can be effectively limited, improving the stability of the movement of the first transmission member 5 and the second transmission member 6 under the drive of the rotary drive assembly, and resulting in better overall structural stability of the ear-picking adjustment device.

[0044] Furthermore, bearings are provided on both the first rotating shaft 1 and the second rotating shaft 2. The ends of the first support member 41 hinged to the second rotating shaft 2 and the second support member 42 hinged to the first rotating shaft 1 are both connected to the outer peripheral wall of the bearings. The bearings allow for smooth swing adjustment between the first support member 41 and the second rotating shaft 2, and between the second support member 42 and the first rotating shaft 1. Further, multiple limiting members are arranged on both sides of the bearing at intervals to limit bearing movement and prevent the bearing from sliding along the length of the first rotating shaft 1 or the second rotating shaft 2. In a preferred embodiment, the limiting member is a limiting bushing.

[0045] like Figure 1As shown, in this embodiment, the rotary drive assembly further includes a gear component 43, a rotary drive component, and racks 44. The rotary drive component is driven by the gear component 43. Two racks 44 are arranged parallel to each other on both sides of the gear component 43, and the opposite sides of the two racks 44 mesh with the gear component 43. The ends of the two racks 44 are detachably connected to the first transmission component 5 and the second transmission component 6, respectively, facilitating assembly and disassembly. This embodiment uses a gear drive, with the rotary drive component being a drive motor. The rotation of the drive motor drives the gear component 43 to rotate, thereby causing the two racks 44 to move in an alternating motion. This, in turn, drives the two rotating shafts to rotate in opposite directions via the first transmission component 5 and the second transmission component 6. In this embodiment, the gear drive has high transmission efficiency, a stable transmission cycle, and a compact overall structure, resulting in a long service life for the ear-picking adjustment device. In this embodiment, the first transmission member 5 has a bent portion at one end of the toothed plate arranged on the first transmission member 5. The purpose of this is to avoid other structures and leave more space for other structures. If it is not necessary to avoid other structures, it can be adapted to be a straight plate structure like the second transmission member 6.

[0046] like Figure 1 As shown, in this embodiment, the picking plate 3 also includes a gear guard 9. The gear guard 9 forms a protective space for accommodating the gear 43. The gear 43 is detachably connected to the gear guard 9. By arranging the gear guard 9, the position of the gear 43 can be fixed, so that the gear 43 rotates around the fixed point. On the other hand, it can also effectively protect the gear 43 and prevent external impacts from damaging the gear 43 and affecting the normal operation of the picking adjustment device.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, the gear protective component 9 has an insertion interface. The end of the rack 44 facing away from the transmission component passes through the insertion interface and the protective space in sequence. The end of the rack 44 facing away from the transmission component forms a limiting protrusion 441. The limiting protrusion 441 cooperates with the top surface of the gear protective component 9 to limit the movement of the rack 44 and prevent the rack 44 from slipping out of the protective space and affecting the normal operation of the ear-picking adjustment device.

[0048] like Figure 1 and Figure 3As shown, in this embodiment, the harvesting plate 3 also includes adjusting members 10. Two adjusting members 10 are provided on each of the first rotating shaft 1 and the second rotating shaft 2. The number of adjusting members 10 can be adjusted according to actual needs. The harvesting plate 3 includes a plate body and a fork shaft 31 extending outward from the plate body. The adjusting members 10 are rotatably connected to the fork shaft 31. When the first rotating shaft 1 and the second rotating shaft 2 rotate around their own axes under rotational driving force, because the adjusting members 10 are rotatably connected to the fork shaft 31, they will move together, thereby driving the harvesting plate 3 arranged on the first rotating shaft 1 to swing around the first rotating shaft 1, and the harvesting plate 3 on the second rotating shaft 2 to swing around the second rotating shaft 2, causing the two harvesting plates 3 to move closer or further apart, thereby achieving the effect of adjusting the size of the harvesting space.

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, a storage groove is formed on the picking plate 3, and the fork shaft 31 is engaged in the storage groove and fixedly connected to the picking plate 3. Specifically, the fork shaft 31 can be fixed in the storage groove by welding, resulting in good connection stability. The adjusting member 10 has an open groove for the fork shaft 31 to pass through. The opening size of the open groove is smaller than the diameter of the fork shaft 31 to ensure that the adjusting member 10 will not slip off the fork shaft 31. Furthermore, the upper plate body of the picking plate 3 also has a clearance groove corresponding to the adjusting member 10. There are multiple clearance grooves, each corresponding to one of the adjusting members 10, to avoid interference between the adjusting member 10 and the plate body, which would affect the adjustment and movement of the picking plate 3.

[0050] like Figure 1 As shown, in this embodiment, the ear-picking plate 3 is also provided with an adjustment hole 32, which extends along the width direction of the ear-picking plate 3. The ear-picking adjustment device also includes a locking member 20, which passes through the adjustment hole 32 and is connected to the ear-picking plate frame. The locking member 20 is used to limit the ear-picking plate 3 and can slide along the adjustment hole 32. By arranging the locking member 20, the ear-picking plate 3 can be restricted from swinging, so that the ear-picking plate 3, which originally swings circumferentially around the first rotating shaft 1 or the second rotating shaft 2, is converted into an ear-picking plate 3 that moves linearly along the width direction of the ear-picking plate 3. The adjustment stability is better, and interference with other structures can be further avoided during the operation of the ear-picking plate adjustment device.

[0051] The method for adjusting the harvesting space between the two picking plates 3 is as follows:

[0052] The gear 43 is driven to rotate by the rotary drive component, which in turn drives the racks 44 on both sides to move. The racks 44 on both sides move in opposite directions, which in turn drives the first transmission component 5 and the second transmission component 6 to move in opposite directions. At this time, the first connecting component 7 drives the first rotating shaft 1 to rotate around its own axis, and the second connecting component 8 drives the second rotating shaft 2 to rotate around its own axis. The rotation directions of the first rotating shaft 1 and the second rotating shaft 2 are opposite, thereby causing the two ear-picking plates 3 to move closer or further apart, thus achieving the purpose of adjusting the harvesting space.

[0053] like Figure 1 As shown, in this embodiment, the picking board frame is also provided with a fixed seat 30. Both ends of the fixed seat 30 extend into the fixed seat 30 along the length direction of the first rotating shaft 1 or the second rotating shaft 2 and are rotatably connected to the fixed seat 30. By arranging the fixed seat 30 at the ends of the first rotating shaft 1 and the second rotating shaft 2, the stability of the first rotating shaft 1 and the second rotating shaft 2 rotating around their own axes can be effectively ensured.

[0054] In this embodiment, a harvester is proposed, including the ear-picking plate adjustment device described above. As in this application, the ear-picking plate adjustment device can be applied to a corn harvester to adapt to different ear heights and sizes, thereby optimizing the harvesting process, reducing downtime, and improving overall harvesting efficiency. Furthermore, operators can use a corresponding control system to adjust the first and second shafts by controlling the rotary drive assembly, reducing labor intensity and lowering labor costs. Since the harvester employs all embodiments of the ear-picking plate adjustment device, it also possesses all the beneficial effects of the device, which will not be elaborated upon here.
