Potato planting machine matching with hand tractor for use

Abstract

A potato planting machine matching with a hand tractor for use is disclosed. The machine comprises a big rack; a driving rack, which is used for connecting a hand tractor, is arranged on the front end of the big rack; ground wheels, which are used for moving, are arranged on the bottom of the big rack; a seed box is arranged on the big rack; a vertical seed transporting pipe is arranged in front of the seed box; a seed lifting shaft is arranged above the seed box, a seed lifting chain with a seed lifting spoon is arranged between the seed lifting shaft and one output shaft of a four-speed speed controller; a wood vibration preventing board is arranged on the side wall of the seed box behind the seed lifting chain; and the input shaft of the four-speed speed controller is connected to a ground wheel shaft through a chain. The potato planting machine integrates the functions of ditching, fertilizing, sowing, ridging and pressing together, and is capable of precisely lifting the potatoes to the seeding transporting pipe and sowing the potatoes evenly. The wood vibration preventing board can prevent the potato seeds from falling back to the seed box because of vibration, and thus the seed lifting rate is improved. The free adjustment of the row spacing of the potatoes in a certain range is achieved through the design of the four-speed speed controller, and the requirement of farmers is satisfied. The vibration and resistance during the work process can be relieved by the damping spring.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a potato planter matched with a walking tractor. Background technique [0002] In mountainous areas such as Qinghai, potato planting mostly relies on manual sowing, which is time-consuming and laborious, with uneven sowing and irregular ridges. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of prior art, the object of the present invention is to provide a kind of potato planter that is used together with walk-behind tractor, integrate ditching, fertilization, sowing, ridging, suppression into one, realize planting standardization. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A potato planter used in conjunction with a walking tractor, comprising a large frame 20, a traction frame 3 connected to the walking tractor at the front end of the large frame 20, ...
