[0001] The utility model relates to the technical field of mowers and windrowers, in particular to a reel assembly with automatically retractable spring teeth, a cutting platform and a mower and windrower. Background Art

[0002] The main reaper and sun-drying machine currently used on the market includes a harvesting table, on which a straw-pushing assembly is rotatably arranged, and a conveying mechanism is arranged below the straw-pushing assembly, and the straw-pushing assembly includes a plurality of spring teeth for pulling the crops; as the harvesting table moves forward, during the process of harvesting crops such as rapeseed and wheat, the cutting knives on the harvesting table cut off the stems of the crops, and the rotating spring teeth pull the crops from below the harvesting table to the conveying mechanism, so that the crops are spread from the inside of the harvesting table to the ground through the conveying mechanism, and then subsequent operations are carried out.

[0003] During this process, the spring teeth push the crops from the front of the harvesting table to the back of the harvesting table, and then when they rotate back to the front, the crops transmitted to the transmission mechanism will be pushed upward and brought back. Especially when large feeding volumes are required, a large amount of stems will be brought back, resulting in poor operating results. Utility Model Content

[0006] The eccentric track disk is rotatably connected to the support shaft, and the eccentric track disk is rotatably connected to the support shaft.

[0007] The beneficial effect of the utility model is that during use, the power source drives the supporting shaft to rotate, driving the eccentric amplitude disk, the eccentric trajectory connecting rod, the spring tooth tube and the connecting seat to rotate at the same time. During this process, the eccentric amplitude disk and the eccentric trajectory disk rotate relatively, the middle end of the eccentric trajectory connecting rod rotates and is slidably connected to the long groove track, the middle end connecting part forms a fulcrum, and one end of the eccentric trajectory connecting rod rotates and is slidably connected to the circular track. The circular track is used to form an eccentric guiding effect, so that the eccentric trajectory connecting rod moves as a whole, driving the connecting seat, the spring tooth tube and the spring tooth to rotate with the center line of the spring tooth tube as the center axis. When one end of the eccentric trajectory connecting rod rotates and is slidably connected to different positions of the circular track, the spring tooth retracts and contracts to different degrees, so that the spring tooth extends to the longest when rotating outward and retracts to the shortest when rotating inward. Therefore, during operation, the spring tooth can rely on this movement to reduce the back-draft of the stem, so as to improve the technical problem of stem back-draft in the existing straw-pulling assembly when the crops are pushed downward to the rear and rotated.
