Abstract
Description
Technical Field
[0001] This utility model relates to the field of corn harvesting technology, and more specifically, to a header adjustment ruler. Background Technology
[0002] Corn harvesting requires the use of a corn harvester. During operation, a header adjustment ruler is needed to adjust the gap between the ear-picking plate and the stalk-pulling roller of the corn harvester's plate header. However, most existing adjustment rulers are simple T-shaped structures with fixed dimensions for adjusting the gaps. Due to varying needs, many different sizes of adjustment rulers are required for gap adjustment, necessitating frequent ruler changes and making the adjustment process cumbersome. Therefore, we propose a new header adjustment ruler. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cutting table adjustment ruler to solve the technical problem that the current gap adjustment process requires frequent ruler changes and is complicated.

[0005] Preferably, the support plate consists of a smooth slope and a straight support, wherein the straight support is a contact support surface and is positioned parallel to the long axis of the insertion ruler, and the smooth slope is a sloping arc surface inclined towards the insertion ruler.
[0006] Preferably, the support plate is further provided with a sliding seat, and the bottom of the hanging ruler head is provided with a sliding groove, and the sliding seat slides with the sliding groove.
[0007] Preferably, the reciprocating telescopic structure includes a bidirectional screw, which is rotatably connected to the bottom of the cavity, and both ends of the bidirectional screw are threaded with nut seats.

[0010] Preferably, a hammer head is provided above the through-hole rotating head, the hammer head is fixed to the hanging ruler head, and a circular cavity is formed in the center of the hammer head.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the limiting sliding design of the support plate and the hanging ruler head, and the numerical value engraved on one side of the hanging ruler head, allows the position of the support plate to be adjusted according to the situation. Furthermore, through the threaded sleeve of the bidirectional screw and nut seat, and the symmetrical hinge of the transfer plate, when the through-rotor head is rotated, the connecting plate can move to both sides synchronously, further enabling the support plate to move synchronously. Thus, the adjustment part can be conveniently and steplessly adjusted according to the situation, allowing the use of only one ruler to replace multiple rulers of different specifications, improving its convenience and solving the problem of frequent ruler changes and complicated adjustment process during gap adjustment.
[0013] 2. This utility model also utilizes the straight support of the support plate and the close contact of the side of the gap, as well as the slope design of the smooth slope. Furthermore, the design of the hammer head and the design of the central cavity of the hammer head facilitates adjustment using tools. When the gap is close to the desired gap, the design of the hammer head and the smooth slope allows for quick and easy gap adjustment by using a small hammer, thus improving the convenience of adjustment and further solving the problem of complicated adjustment process.

[0020] like Figures 1 to 4As shown, this utility model relates to a cutting table adjustment ruler, including a T-shaped adjustment ruler body 1. The adjustment ruler body 1 consists of an insertion ruler 101 and a hanging ruler head 102. The bottom of the hanging ruler head 102 is a hanging surface, and the corresponding distance values are engraved on one side of the hanging ruler head 102. A cavity 2 is formed in the upper half of the insertion ruler 101, and support plates 3 are provided on both sides of the edge of the cavity 2. A sliding seat 5 is also provided on the support plate 3. A sliding groove is formed in the bottom of the hanging ruler head 102, and the sliding seat 5 slides with the sliding groove. Since the balance and stability of the gap adjustment on both sides are very important when adjusting the gap, it is necessary to make the sliding seat 5 expand to both sides synchronously. To address this point, a corresponding telescopic device is installed in the central area of the cavity 2. Structure 4, the equal telescopic structure 4 includes a bidirectional screw 401. The two ends of the bidirectional screw 401 have threads in opposite directions. The bidirectional screw 401 is rotatably connected to the bottom of the cavity 2. Nut seats 402 are threaded on both ends of the bidirectional screw 401. Pulling plates 403 are rotatably connected to both sides of the outer periphery of the nut seats 402. A connecting plate 404 is hinged between the pulling plates 403 on the same side. The connecting plate 404 is connected to the support plate 3. In order to facilitate the rotation operation of the bidirectional screw 401, a through-hole head 6 is installed on the top of the bidirectional screw 401. The through-hole head 6 passes through the hanging ruler head 102 and has a slot on the top. The slot is adapted to external tools, so that the tool can be inserted into the slot to operate the rotation.
[0021] Working principle: When needed, insert a tool into the slot and rotate it to drive the bidirectional screw 401 to rotate, which in turn drives the nut seat 402 to move synchronously in the opposite direction, causing the transfer plate 403 to move synchronously, so that the connecting plate 404 and the support plate 3 move synchronously. Then, according to the engraved value, the gap can be adjusted steplessly, so that one adjustment ruler can replace multiple adjustment rulers, making gap adjustment more convenient.
[0022] Furthermore, the support plate 3 is provided with a smooth slope 301 and a straight support 302. The straight support 302 is a contact support surface and is positioned parallel to the long axis of the insertion ruler 101. The smooth slope 301 is a sloping arc surface inclined towards the insertion ruler 101. A hammer head 7 is provided above the penetrating rotating head 6. The hammer head 7 is fixed to the hanging ruler head 102. A circular cavity is opened in the center of the hammer head 7. The tool can pass through the circular cavity without being affected.
[0023] In terms of working principle and specific operation, the gap between the picking plates is usually adjusted to be narrower at the front and wider at the back (generally, the rear end is 5 mm wider than the front end). First, loosen the fixing bolts of the picking plates and roughly adjust them to a similar size. At this time, the smooth slope 301 will be placed on the top of the picking plate. Then, use a small hammer to tap the hammer head 7 to make the smooth slope 301 gradually squeeze into the gap until the straight support 302 is in contact with the side of the picking plate. The adjustment is then completed. This design eliminates the need for frequent fine adjustments and further improves the convenience of adjustment.
[0024] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
