Rotary tillage type combined fertilizer-and-seed drill matched with hand tractor

Abstract

The invention discloses a rotary tillage type combined fertilizer-and-seed drill matched with a hand tractor. The rotary tillage type combined fertilizer-and-seed drill is composed of a rack, a rotary tillage device, a sowing and fertilizing device, a press wheel, a gear box and a sprocket wheel case, wherein the rotary tillage device is arranged below the rack and comprises a knife roller and a shell, a knife shaft and a blade form the knife roller, the blade is arranged on the knife shaft, the sowing and fertilizing device is arranged on the rack and is composed of a seed box, a seed discharging device, a seed discharging shaft, a seed delivery pipe, a fertilizer box, a fertilizer discharging device, a fertilizer discharging shaft, a fertilizer delivery pipe, a ditcher and a discharging capacity regulator, the press wheel is arranged at the rear of the rack, an input shaft of the gear box is connected with a power output shaft of the hand tractor, power of the hand tractor is transmitted to the rotary tillage device by virtue of a gear transmission mechanism in the gear box and a sprocket transmission mechanism in the sprocket wheel case, and the press wheel drives the seed discharging shaft and the fertilizer discharging shaft to operate by virtue of a chain mechanism. The rotary tillage type combined fertilizer-and-seed drill disclosed by the invention has the advantages that labour intensity can be greatly reduced, soil preparation, sowing and fertilizing efficiency can be improved, farming season can be shortened, and production cost can be reduced.

Description

Technical field: [0001] The invention relates to the field of agricultural machinery, and mainly relates to a rotary tillage and fertilization drill which is matched with a walk-behind tractor and can complete multiple processes such as crushing soil, sowing, fertilizing, and pressing. Background technique: [0002] At present, most of the compound operation machines for rotary tillage, fertilization and seeding in dry land are large and medium-sized implements, and large and medium horsepower tractors are needed as power. The fields in hilly and mountainous areas are small, and it is difficult for large and medium-sized machines to work on the ground. Moreover, there are many walk-behind tractors in hilly and mountainous areas, and the supporting machinery for soil preparation, sowing, and fertilization has single functions. Dry farming requires multiple field operations for sowing, which is low in efficiency and high in cost. . In the field of rotary tillage drills. Ther...

Problems solved by technology

[0003] The purpose of the present invention is to make up for the defects of the prior art, and to provide a rotary tillage and fertilization seed drill matched with a walk-behind tractor. There are many power and power machines, the function of soil preparation, sowing and fertilization machines is single, manual work is still the main method, labor intensity is high, and efficiency is low. Provide a simple structure, long service life, easy to manufacture and facilitate mass production, and can be used at the same time. A rotary tillage drill that integrates multiple functions such as seeding, fertilization and soil crushing
