Figure 2 and Figure 3 As shown, an adjusting mechanism 4 is correspondingly arranged at the side end of each ear picking roller 3 , and the height of the corresponding ear picking roller 3 and the interval between two adjacent ear picking rollers 3 are controlled by the adjusting mechanism 4 .

[0025] Preferably, it includes an adjustment mechanism 4, such as Figure 4As shown in the figure, the adjusting mechanism 4 is arranged between the ear picking roller 3 and the cutter bar frame 1. The adjusting mechanism 4 includes an adjusting cylinder 41, an adjusting member 42 and an adjusting fork 43. The adjusting cylinder 41 is fixedly installed on the cutter bar frame 1. A vertical sliding groove is provided on the adjusting cylinder 41. The adjusting member 42 is slidably arranged in the sliding groove. The adjusting fork 43 is arranged on the adjusting member 42. The adjusting fork 43 is connected to the ear picking roller 3. The adjustment of the ear picking roller 3 is realized by the movement of the adjusting fork 43.

The first adjusting screw rod 5 passes through the fixing plate 44 and extends to the outside of the adjusting cylinder 41. A first adjusting nut 51 is provided on the first adjusting screw rod 5. The first adjusting nut 51 is located outside the adjusting cylinder 41 and contacts the fixing plate 44. The first adjusting nut 51 meshes with the first adjusting screw rod 5. By rotating the first adjusting nut 51, it is possible to control the second adjusting screw rod 6 to drive the adjusting member 42 to move up and down in the adjusting cylinder 41.

[0027] Among them, a second adjusting screw rod 6 is provided on the side of the adjusting fork 43 close to the adjusting cylinder 41. A through hole is provided on the adjusting member 42. The second adjusting screw rod 6 passes through the adjusting cylinder 41 and the through hole on the adjusting member 42. Two second adjusting nuts 61 are provided on the second adjusting screw rod 6. The two second adjusting nuts 61 are respectively located on both sides of the adjusting cylinder 41. The two second adjusting nuts 61 mesh with the second adjusting screw rod 6. By rotating the adjusting nut, it is possible to control the first adjusting screw to drive the adjusting fork 43 to move left and right.

[0028] In the present solution, a through oblong hole 411 is provided on the adjusting cylinder 41. The second adjusting screw rod 6 is embedded in the oblong hole 411. By providing the oblong hole 411, the requirement for the second adjusting screw rod 6 to pass through the adjusting cylinder 41 can be met. At the same time, the up and down position of the second adjusting screw rod 6 is limited by the provided oblong hole 411 to ensure the stability of the lifting adjustment of the adjusting member 42.

[0029] Optionally, two second adjusting nuts 61 are provided in the present solution to fix the second adjusting screw rod 6. After the adjustment is completed, the two second adjusting nuts 61 on both sides are rotated to press the adjusting cylinder 41 to achieve fixation, thereby ensuring the adjustment stability of the adjusting mechanism 4.

[0033] Preferably, as Figure 5 shown, a transmission ball head 21 is provided at the output end of the power unit 2. A ball head groove 32 is provided on the side of the ear picking roller 3 close to the power unit 2. The transmission ball head 21 is embedded in the ball head groove 32. A transmission rod 22 is provided on the transmission ball head 21. A transmission notch is provided on the ball head groove 32. The transmission rod 22 on the transmission ball head 21 is embedded in the transmission notch on the ball head groove 32, so as to ensure that the power can still be stably transmitted after the adjustment of the adjusting assembly.

[0034] Optionally, the first adjusting screw rod 5 in this solution is provided on the lower end surface of the adjusting member 42 and is in a vertical state. The fixing plate 44 is provided on the lower end surface of the adjusting cylinder 41. Therefore, the first adjusting nut 51 can be installed at a position below the fixing plate 44. And because a reel assembly and the like are also provided on the upper end of the combine harvester cutting table, setting the first adjusting nut 51 downward can better facilitate the staff to adjust it.

[0035] When this solution is used, first loosen the two second adjusting nuts 61, and then rotate the first adjusting nut 51 according to the harvesting requirements to control the set height of the adjusting member 42. The adjusting member 42 drives the side of the ear picking roller 3 away from the power unit 2 to adjust the height. After the adjustment is completed, the position relationship of the two second adjusting nuts 61 can be controlled according to the requirements to adjust the lateral position of the adjusting fork 43. At this time, the interval between the two ear picking rollers 3 is adjusted. After the adjustment is completed, tighten the two second adjusting nuts 61, so that the two second adjusting nuts 61 are clamped on the adjusting cylinder 41 to complete the fixation.
