Problems solved by technology

But Japan is a single-cropping rice country, and its subplanting mechanism is mainly applicable to the small seedling operation (early rice transplanting) of rice seedlings, referring to "Agriculture, Animal Husbandry and Food Machinery 1990 (5) 7th to 10th pages; It can be planted for one season, so its use range is greatly reduced

Embodiment Construction

[0018] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the spur-toothed elliptical gear planetary system insertion mechanism of the present invention includes a transmission component and a planting arm component. The transmission parts include a driving sprocket 18 mounted on the transmission shaft 17 in the sprocket box, which is connected with the central sprocket 1 mounted on the central shaft 3 through a chain 19. The left and right sides of the sprocket box are respectively equipped with a gear box 16, 16', gear boxes 16, 16' are equipped with central cylindrical gears 10, 10' on both sides of the central shaft 3, and the two ends of the central shaft 3 respectively use splines to drive the gear boxes 16, 16' to rotate, and the central cylindrical gears at both ends 10,10' are respectively fixed on the sprocket case by flanges 2,2'. The two sides of the central cylindrical gear 10, 10' in the left and right gear boxes 16, 16' are respectively symmetrica...

Abstract

A planetary gear train type rice seedling transplanter is disclosed. A left and a right gear boxes are driven by a central sprocket in a sprocket case for making them rotate. Two cylindrical planetary gears engaged with the static central cylindrical gear in the said gear box rotate with the gear box to drive the coaxial elliptical gear to rotate, and the said elliptical gear is further engaged with the elliptical planetary gear, so resulting in that the said elliptical gear rotates at non-uniform speed relatively to the gear box. The absolute movement of a transplanting arm pair is the composition of the circumference movement of gear box and the non-uniform movement of elliptical planetary gear. Its advantages are low inertial force, no damage to rice seedlings and reasonable structure.

Description

technical field [0001] The invention relates to a planting mechanism of a motorized rice transplanter, which is a cylindrical-toothed elliptical-toothed planetary system splitting mechanism. Background technique [0002] At present, the rice motor-driven rice transplanter sold on the domestic market has two forms of its planting mechanism: a kind of is a crank rod type splitting mechanism, and another kind is a rotary splitting mechanism. The former can work normally when the working frequency is 200-220 times / min. With the increase of the frequency of the rice transplanter, the vibration of the rice transplanter frame will be intensified; The defects such as the increased rate and missing seedling rate and the fragile planting arm limit the improvement of work efficiency. The latter is an eccentric gear and an elliptical gear mechanism as developed by Japan, see "Jilin Rural Mechanization" 1991 (5) page 35 and "Modern Agriculture" 1995 (11) 29-31...
