Description

Technical Field

[0001] This utility model relates to the field of cutting table technology, and more specifically, to a telescopic tooth adjustment device. Background Technology

[0002] Telescopic teeth are an important component of harvesters. For example, publication number CN2768409Y, titled "Header Telescopic Screwdriver with Full-Length Distribution," discloses a "header telescopic screwdriver with full-length distribution, which includes an auger cylinder, blades, and a screwdriver cylinder. The screwdriver cylinder is located in the middle, with auger cylinders on both sides. Blades with opposite rotation directions are provided on the auger cylinders, rotating towards the center in coordination with the rotation direction of the auger cylinders. Telescopic screwdrivers are also provided along the entire length of the auger cylinder." This technical solution improves gripping ability and uniform feeding performance through the auger cylinder, blades, screwdriver cylinders, and telescopic screwdrivers.

[0003] To improve crop feeding efficiency, it is necessary to strictly control the length of the telescopic fingers extending out of the auger cylinder. This requires rotating a shaft that is eccentrically positioned with the auger. The rotation of the eccentric shaft drives the telescopic fingers to extend out of the auger. However, the auger with telescopic fingers distributed throughout the header disclosed in this technical solution does not provide an adjustment device for adjusting the extension of the telescopic fingers out of the auger cylinder. During the adjustment process, one can only rotate the eccentric shaft or the auger cylinder based on experience, resulting in low adjustment accuracy. Furthermore, installing this device on the header requires directly fixing the shaft to the header, and the impact force during use is directly applied to the shaft, which can easily lead to shaft deformation or damage.

[0004] Therefore, there is an urgent need for a device that facilitates the adjustment of the telescopic teeth's extension and retraction. Utility Model Content

Adjusting the support shaft 2 does not require direct operation on the support shaft 2, thus protecting the support shaft 2 and preventing damage during adjustment, while improving adjustment accuracy. The connection between the adjusting member 3 and the connecting member 4 means that fixing the connecting member 4 also fixes the support shaft 2. This eliminates the need to fix the device to the equipment by fixing the support shaft 2; only the connecting member 4 needs to be fixed to the equipment, further protecting the support shaft 2.

[0026] The adjusting component 3 includes an adjusting cylinder 32, and the end of the support shaft 2 is provided with a spline 21. The adjusting cylinder 32 is inserted into the spline 21. The adjusting cylinder 32 is inserted into the support shaft 2 through the spline 21, which facilitates the replacement of the adjusting cylinder 32. Rotating the adjusting cylinder 32 drives the support shaft 2 to rotate, thereby realizing the adjustment of the support shaft 2.

[0027] The adjusting device 31 includes an adjusting disc 311, which is coaxially fixed with the adjusting cylinder 32.

Tightening the nut securely fixes the adjusting device 31 and the mounting plate 41. Because the adjusting grooves 312 are arranged around the adjusting cylinder 32, the adjusting device 31 and the mounting plate 41 can rotate freely. Therefore, the adjusting cylinder 32 can drive the support shaft 2 to rotate. When it rotates to the desired position, the bolt and nut securely fix the adjusting device 31 and the mounting plate 41, achieving free adjustment of the support shaft 2. Simultaneously, the mounting plate 4 can be used to fix the support shaft 2.

[0032] The adjusting cylinder 32 has at least two rotating grooves 321 at one end, and the two rotating grooves 321 are symmetrically arranged about the adjusting cylinder 32.
