Description

Multi-purpose cultivator for dibbling and fertilizing

The utility model relates to a kind of multipurpose program request Fertilizing cultivator, and this machine is drawn by hand tractor, and operations such as trench digging, fertilising, sowing are once finished.

Current rural area field seeding mainly adopts the sower of animal power sower and tractor-drawn, Chinese patent CN 2049459 disclosed grain seeders are exactly wherein a kind of, this machine is made up of feed mechanism, transmission mechanism, land wheel, plough and rack chassis, this machine can hang with hand tractor and be connected, the single armed draw beam hangs during operation, the tractor two-wheeled lands, and radius of turn is little.But the feed mechanism automaticity of this machine is not high, and the operator needs with the tractor walking, also need firmly tractor driver be suspended from the ground lifting and drive this machine during turning, so labour intensity is bigger.

The purpose of this utility model is to propose a kind of multipurpose program request Fertilizing cultivator, and this machine only needs one man operation just trench digging, fertilising, sowing, pressure ground four procedures once can be finished, and can intertill operation in addition.

The purpose of this utility model is achieved in that a kind of multipurpose program request Fertilizing cultivator, the rack chassis of this machine is by door-shaped frame, preceding crossbeam, rear cross beam and draw bar are formed, the seed manure storehouse is equipped with in the rack chassis front portion, two plough Ditching machine frames are equipped with at the rear portion, on the crossbeam of described back mounting is installed, hinged pressure ground mechanism under this mounting, this presses ground mechanism by pressing the ground roller, pressure roller shaft, depression bar, spring, sleeve pipe is formed, quantitative conveying roller is installed on the described seed manure storehouse, this quantitative conveying roller axle head is equipped with minor sprocket, on the described land axle hinge wheel is installed, on two sprocket wheels chain is housed, be mixed bucket and carrier pipe are quantitatively installed below the conveying roller in seed manure storehouse bottom.The utility model is drawn by hand tractor, the operator is sitting in and can drives tractor simultaneously on the seat of mounting and the utility model carries out operation, tractor to overtake, plough on two plough Ditching machine frames can be left trench, under the hinge wheel on the land wheel drives, quantitatively conveying roller rotates, and seed in the seed manure storehouse and fertilizer discharge are entered trench through carrier pipe, presses ground mechanism subsequently it to be covered pressing with soil.

Quantitatively conveying roller is crowded broken in order to prevent the seed quilt, in bottom, described seed manure storehouse and quantitative conveying roller joint portion elastic guard plate is housed.For saving fertilizer and sowing evenly, the uniform seed distributing groove of an end of described quantitative conveying roller, the uniform defertilizing slot of the other end.This roller whenever circles and will discharge quantitative seed and fertilizer, and seed fertilizer is mixed evenly.

The utility model has following advantage, because this machine only needs one man operation just trench digging, fertilising, sowing, pressure ground four procedures once can be finished, the automaticity height, easy and simple to handle, save manpower, because the operator can be sitting in driver behavior on the seat, labour intensity is lower, the utility model can also be intertilled operation in addition, and purposes is more.

The utility model is described in further detail below in conjunction with drawings and Examples.
