Description

Technical Field

[0001] This utility model relates to the field of corn harvesting technology, specifically a multi-segment combined ear-picking plate type corn header. Background Technology

[0002] The multi-segment combined ear-picking plate type corn header is a special header for corn harvesters (or corn ear pickers). Its core feature is the use of segmented ear-picking plate design. Through the combined movement of multiple sets of ear-picking plates, it can achieve efficient and low-damage picking of corn ears.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Multi-Segment Combined Ear-Picking Plate Type Corn Header," patent application number: 201620099518.X. It includes a gearbox, frame, stalk-pulling roller assembly, and stalk-reeling chain assembly. The gearbox includes a ball head. The frame includes a main frame, a chain guard plate, and a chain guard plate support plate. The upper surface of the main frame has longitudinal long slots. The corn header also includes a rear ear-picking plate assembly and an inlet ear-picking plate assembly. Dividing the entire ear-picking plate into an inlet ear-picking plate and a rear ear-picking plate enhances the passage of corn stalks while ensuring the clamping effect of the ear-picking plate on the stalks. Both ear-picking plates can be automatically adjusted, facilitating non-row harvesting. The overall header width is relatively narrow, allowing it to be used as a narrow-row harvester or a wide-row harvester. However, in the aforementioned corn header, the gap adjustment between the ear-picking plates is done by adjusting multiple plates as a whole, rather than adjusting them separately. This results in an inability to adapt to plants of different sizes, affecting the quality of the corn header's use.

[0004] Therefore, the corn header needs to be redesigned and modified to effectively prevent the inability to adjust the sections separately. Utility Model Content

The top of the fixed plate 12 is fixedly connected to a return spring 13, and the top of the return spring 13 is fixedly connected to a moving plate 14. The back of the moving plate 14 is slidably connected to the connecting plate 10, and the top of the moving plate 14 is fixedly connected to a top rod 15. The top of the top rod 15 extends through the interior of the irregular rod 9.

[0039] As a technical optimization of this utility model, the disassembly and assembly mechanism 11 enables the ear-picking plate assembly 3 to be disassembled and cleaned, thus increasing the convenience of disassembly and assembly.

[0040] refer to Figure 3 The front of the connecting plate 10 is provided with a moving groove 16, and the back of the moving plate 14 is slidably connected to the inside of the moving groove 16.

[0041] As a technical optimization of this utility model, by setting the moving groove 16, the moving plate 14 can slide more smoothly inside the connecting plate 10, reducing the friction between the moving plate 14 and the connecting plate 10.

[0042] refer to Figure 5 The bottom front side of the irregular rod 9 has a top groove 17, and the top of the top rod 15 is engaged inside the top groove 17.

[0043] As a technical optimization of this utility model, the top groove 17 enables the top rod 15 to be more securely engaged inside the irregular rod 9, preventing it from falling off.

[0044] refer to Figure 5 A handle 18 is fixedly connected to the front of the movable plate 14, and the handle 18 is used in conjunction with the movable plate 14.

[0045] As a technical optimization of this utility model, the handle 18 makes it easier for users to pull the movable plate 14, thus increasing user convenience.

[0051] As a technical optimization of this utility model, the setting of the base 21 enables the double-end motor 5 to operate more stably and prevents shaking.

[0052] The working principle and usage process of this utility model are as follows: First, when the user needs to adjust the gap in sections, the double-end motor 5 is started. The output end of the double-end motor 5 drives the positive and negative threaded rods 6 to rotate. The positive and negative threaded rods 6 drive the translation sleeve 7 to move inward. The translation sleeve 7 drives the irregular rod 9 and the connecting plate 10 to move inward. The connecting plate 10 drives the picking plate assembly 3 to move inward, so that multiple picking plate assemblies 3 can be adjusted separately for gap adjustment, achieving the effect of multi-section adjustment. Then, when it is necessary to disassemble the picking plate assembly 3, press down the handle 18. The handle 18 drives the moving plate 14 to move downward. The moving plate 14 drives the top rod 15 to move downward, so that the top rod 15 is disengaged from the inside of the top groove 17. Then, the connecting plate 10 and the picking plate assembly 3 can be pulled out, achieving the effect of easy disassembly and assembly.

[0053] In summary, this multi-segment combined ear-picking plate corn header changes the traditional method of adjusting multiple segments together. By using a special-shaped rod 9 to drive the connecting plate 10 for left and right adjustment, it can be adjusted segment by segment, which can adapt to plants of different sizes and improve the quality of corn header use.
