Description

Weeds up-rooting machine

Technical field

The utility model relates to farm machinery, be meant that especially a kind of expansion link by the adjustment front-wheel stretches, and to realize its lifting, can make set of knives adjust according to the depth difference of weeds root growth, easy and simple to handle, thoroughly uproot weeds root and while plowed soils are beneficial to plough the Weeds up-rooting machine of farming.

Background technology

General farmland is before the plantation crops, all having one section lies fallow the phase, in the easy growth of weeds of interim farmland of lying fallow, in the cultivation of paddy rice, intertill and clean tillage is a ring very important in the rice cropping process, suitable intertill and clean tillage can promote the primary growth of paddy rice, replenish the oxygen in the soil, impel the activity of microorganism in the soil, promote organic decomposition, the weeds of being rooted out after turning in the soil can be used as fertilizer and nourish soil, and after fertilising, intertill and dig, stirring can make fertilizer directly arrive root, the denitrogenation loss that reduces nitrogenous fertilizer is to improve fertilizer efficiency, reach the purpose of volume increase, yet, the general the most traditional original method of uproot weeds is manually to hoe up weeds, dig, this kind tradition very time and effort consuming of mode of hoeing up weeds, and shovel careless poor effect, and the use of general electronic weeder only can be cut except that the weeds stem more than the ground, the weeds root thoroughly can't be rooted out, so behind the plantation crops, weeds meeting and crops grow together, grab the nutrient of crops, make crop growth bad, and the cutter of general present being seen electronic weeder on the market mostly is arranged at the rear, and is nearer from the operator, when operation than tool danger; And it is nearer apart from operator's foot that cutter is provided with the rear, and the operator must bow when work and watch the careless situation of shovel, easily causes neck fatigue, aches; Vibrations were big when known mower used, control difficult, operator's susceptible is to tired, take a broad view of above-mentioned some can learn that traditional electronic weeder causes the user to seek its method in addition because of tool is dangerous with the operating difficulties degree, so spraying agent is present the fastest known and the most effective herbicidal methods, medicament contains toxin, can withered weeds, but the weeding system of this kind spraying agent easily makes the pedo relict toxin, the meeting contaminated soil, and can make soil acidification, behind the plantation crops, can influence the growth of crops, can jeopardize eater's health what is more.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned shortcoming, aim to provide a kind of easy and simple to handle, can adjust shovel grassiness degree according to need, reach the thorough shovel grass and the Weeds up-rooting machine of plowed soils simultaneously.

Technical solution adopted in the utility model is as follows: a kind of Weeds up-rooting machine, mainly be provided with handle and transmission device in Weeds up-rooting machine, drive the careless device uproot weeds of shovel by transmission device, it is characterized in that: this shovels careless device and is positioned at Weeds up-rooting machine the place ahead, shovel careless device and be provided with support, be provided with power transmission shaft in the support, the transmission device of power transmission shaft and Weeds up-rooting machine links transmission, two ends of power transmission shaft are respectively established a driven sprocket, driven sprocket is by another driven sprocket of chain drive below, be provided with set of knives between the driven sprocket that this below is oppositely arranged, set of knives is stretched through to locate by rotating shaft and is provided with, be provided with the cutter chopping block in the rear of set of knives, one front-wheel is arranged at the careless device of shovel the place ahead, the front-wheel top is provided with locating support, locating support is connected by the support of connecting rod with the careless device of shovel, locating support below is provided with expansion link and front-wheel and connects and establish, locating support is provided with the locking element for the expansion link locking positioning, in locating support top be provided with can for adjust expansion link overhanging or in the tommy bar that contracts, flexible by the expansion link of adjusting front-wheel, realize that the set of knives of the careless device of shovel is done liter in the lump according to the depth difference of weeds root growth, the adjustment of falling.

These support two ends that shovel careless device respectively are provided with and are covered with driven sprocket and chain, can prevent that soil and weeds from influencing the clamshell of transmission.

This set of knives is made up of number pedestal and number blade, and blade rear end is provided with and is the upwards block body of bending, and block body the place ahead equidistantly is provided with several rakes.

According to above-mentioned structure, the utlity model has following advantage:

1, can according to institute must shovel grass and plowed soils the degree of depth, adjust the height of set of knives, with the shovel grass that reaches the best and the effect of plowed soils.

2, each blade of set of knives is staggered and is provided with, can more uniform shovel grass and plowed soils, be beneficial to cultivate.

3, set of knives of the present utility model is located at the place ahead, and is far away from the operator, and operation has safety.

4, set of knives is arranged at the place ahead, the operator need not bow, only must direct viewing the place ahead can know and see that set of knives shovels careless situation, and can conveniently control the left and right direction shovel of set of knives grass by the front-wheel guiding, operation very easily, conveniently, and shovel careless device and can not shake when the shovel grass, user's long period of operation can be not tired yet.

5, car body of the present utility model is advanced forward, and the blade of set of knives is rotation backward, when the shovel grass, if there is stone to be embedded in the soil, when blade can be in rotary spading machine buries backward with stone and weeds in the lump by after pass forward and scoop up, make the shovel grass and turn over not interrupted, smooth.

6, when the Weeds up-rooting machine body is operated, earth can not spray to be held, and only can roll in the original place rotation, identical with the principle of artificial weeding, thereby the weeds that scooped up can not buried back more undergroundly, and the weeds that scoop up are behind solar radiation two days later, just can become organic manure, back to nature.

Operating efficiency can be supported ten human efficiencies when 7, using, and is example with the artificial weeding: the weeds on one fen ground need people work on the one eight hours approximately, and work and just can finish in 2nd, but if use the utility model, then only need to finish in 1.5 hours, thereby can be time saving and energy saving.
