Prior to this, a two-stage non-conical gear drive rice pot seedling wide and narrow row transplanting mechanism has been realized. Its work depends on the rotation of the planetary gear system to form a spatial "8"-shaped trajectory. However, in actual operation, due to the The lateral offset of the seedling claw is too large in the first

The invention discloses a quintic polynomial oscillating type wide and narrow row transplanting mechanism for pot seedlings. In an existing wide and narrow row transplanting mechanism for rice pot seedlings, seedling taking paws are large in lateral deflection amount at a seedling taking section, so that the seedling taking positions are inaccurate, and the seedling taking rate is low, and in addition, during seedling pushing, the seedling standing rate is not high due to the influence by the lateral deflection angle of transplanting arms. According to the mechanism, a central shaft can drive two planetary wheel systems at two sides; upper and lower transplanting arms are arranged on the upper parts and the lower parts of gear boxes of the planetary wheel systems; each of the upper and lower transplanting arms comprises a transplanting arm shell, and a main oscillating cam, a secondary oscillating cam, a seedling pushing cam, an oscillating shaft, a seedling pushing rod, and a seedling taking paw which are arranged in the transplanting arm shell; each transplanting arm shell comprises an upper transplanting arm shell and a low transplanting arm shell; each oscillating shaft forms a cam pair with the corresponding main oscillating cam and secondary oscillating cam; each upper transplanting arm shell can oscillate out or oscillate back relative to the corresponding lower transplanting arm shell under the driving of the corresponding oscillating shaft. By using the quintic polynomial oscillating type wide and narrow row transplanting mechanism, the zero deflection amount in the seedling taking process and the zero lateral deflection angle in the seedling pushing process can be realized.
Description
technical field [0001] The invention belongs to the field of agricultural machinery and relates to a wide and narrow row transplanting mechanism, in particular to a quintic polynomial swing type pot seedling wide and narrow row transplanting mechanism. Background technique [0002] Wide and narrow row transplanting refers to the planting method of one wide and one narrow row spacing of the rice pot seedling transplanting machine. This planting method utilizes the principle of crop marginal advantage to increase production, and improves the ventilation and light transmission between plants by adjusting the row spacing of seedlings. Degree, reduce disease (rice blast), increase leaf area index, prolong leaf life, accelerate dry matter accumulation, so as to achieve high quality, high yield, cost saving and efficiency increase. [0003] The wide and narrow row transplanting mechanism for rice pot seedlings is a component for taking seedlings from the acupoints of plastic trays ...
