Potato planter matched with four-wheel tractor

Abstract

The invention discloses a potato planter matched with a four-wheel tractor. The potato planter matched with a four-wheel tractor comprises a large frame, wherein the front end of the large frame is provided with a traction frame connected with the four-wheel tractor, and the rear end of the large frame is provided with ground wheels for walking; the large frame is provided with a seed box; a vertical seed delivery pipe is arranged in front of the seed box; a lower seed lifting shaft is arranged below the seed box; an upper seed lifting shaft with an upper seed lifting chain wheel is arranged above the seed box; a seed lifting chain with a seed lifting spoon is arranged between the upper seed lifting chain wheel and the lower seed lifting shaft; the lower seed lifting shaft is connected with an output shaft of a four-speed speed regulator; an input shaft of the four-speed speed regulator is connected with a driving chain wheel on a ground wheel shaft through a chain. The potato planter matched with a four-wheel tractor integrates with ditching, fertilizing, sowing, ridging, pressing and crop-dusting, can lift potatoes accurately to a seed discharge pipe and can sow uniformly, and achieves plantation standardization; a wooden vibration prevention plate can effectively prevent potato seed blocks from falling back to the seed box because of the vibration of the seed lifting chain, improves the seed lifting rate; the design of the four-speed speed regulator enables the sowing plant spacing of potatoes to be regulated freely within a certain range, and meets requirements of most farmers.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a potato planter matched with a four-wheel tractor. Background technique [0002] With the large-scale planting of potatoes in our country, great progress has been made in the research and development and promotion of machinery suitable for potato production, especially potato planting machinery, but the current potato planting machinery has a large resistance, is not compact in structure, and is not suitable for mountainous areas" There are few flat lands, many mountains, few large plots, and many small plots". Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a potato planter used in conjunction with a four-wheel tractor, which solves the problems of time-consuming and labor-intensive sowing, uneven sowing, and irregular ridge formation. [0004] In orde...
