Description

A kind of double cutting edge roller comb weeder

Technical field

The utility model relates to the technical field of agricultural machinery, in particular to a kind of double cutting edge roller combs weeder.

Background technique

Agricultural planting is technology for the survival of mankind over the past thousands of years, is often given birth in the field in agricultural planting Longer weeds, it is unfavorable that these weeds bring the growth of crops, so needing to remove, otherwise these weeds can consume soil A big chunk nutrient in earth, so that the harvest of crops is had a greatly reduced quality, the crops prevention and control of weeds in the prior art One is to rely on chemical prevention, second is that weeding is carried out by automated machine, third is that manually being removed using farm implements (hoe etc.) Grass, but agricultural product quality and food safety have been seriously affected using chemical prevention (using herbicide etc.) too much, machinery removes Grass also can only carry out broadly weeding to the area of topography broad flat, therefore most safe most effective weeding system still uses Farm implements carry out artificial weeding, and artificial weeding generally uses hoe in reality, but this hoe has a single function and removes in reciprocal In grass movement can only unidirectional weeding, inefficiency is not easy to find weeds accurately simultaneously for the longer weeds to interweave in length and breadth of those stalks Root, influence weeding ratio and weeding quality.

Utility model content

To solve the above-mentioned problems, the utility model proposes a kind of double cutting edge rollers to comb weeder.

Particular content is as follows: a kind of double cutting edge roller combs weeder, which includes bracket, the cutter that is hinged on bracket And it is fixed on the hand-held push rod and roller comb at bracket both ends, it is characterized in that:

The bracket is in U type shape, fixes a hand-held push rod at the U type end of bracket, the hand-held push rod is opposite It is raised upwards in the plane where bracket in the direction far from bracket, one piece of connecting plate is respectively articulated on the two sides of bracket, The free end of two pieces of connecting plates is separately fixed on the both ends of cutter, and the cutter is the plate that two sides are equipped with blade, is being propped up The limit stop post that an opposite side is stretched out is fixed on every side of frame, each pair of limit stop post is located at the connecting plate of respective side The position difference of two sides, the limit stop post of two sides is corresponding, and the limit stop post is swung in inswept range in connecting plate；

The described roller comb include discoid rotating roller, shaft and with the matched casing of shaft, the two of the shaft End, which respectively corresponds, to be fixed on two free ends of bracket, the identical casing of coaxial package at least three in shaft, and adjacent two A rotating roller, the rotating roller are equipped between a casing together with shaft coaxial package.

Preferably, five casings of coaxial package in the shaft, be equipped between two adjacent casings a rotating roller, The rotating roller is together with shaft coaxial package, and the two sides of each rotating roller are close to the end face of the casing of respective side, position It is tightly attached on bracket in the outer end face correspondence of the casing of both ends of the shaft.

Preferably, the hand-held push rod is separately fixed at hand-held equipped with the both ends of two reinforcing rods, every reinforcing rod On push rod and bracket.

Preferably, the free end of the hand-held push rod is equipped with rubber friction layer.

Preferably, the two sides of plane where the cutter and hand-held push rod are located at bracket.

The advantageous effects of the utility model:

Specific embodiment

Embodiment one, referring to Fig. 1-4, a kind of double cutting edge roller comb weeder, the weeder includes bracket, is hinged on bracket Cutter and be fixed on bracket both ends hand-held push rod and roller comb,

The bracket is in U type shape, fixes a hand-held push rod at the U type end of bracket, the hand-held push rod is opposite It is raised upwards in the plane where bracket in the direction far from bracket, one piece of connecting plate is respectively articulated on the two sides of bracket, The free end of two pieces of connecting plates is separately fixed on the both ends of cutter, and the cutter is the plate that two sides are equipped with blade, is passed through During hand-held push rod reciprocating sliding, cutter can carry out cutting weeds by the blade of respective side, make the entire mistake of push-and-pull Journey is in cut state, improves weeding ratio, the limit stop post that an opposite side is stretched out is fixed on every side of bracket, often The two sides of the connecting plate of respective side are located to limit stop post, the position difference of the limit stop post of two sides is corresponding, described Limit stop post is swung in inswept range in connecting plate, and limit stop post limits the swing angle of cutter, and it is suitable to form it into Cutting angle simultaneously provides support for cutting；

The described roller comb include discoid rotating roller, shaft and with the matched casing of shaft, the two of the shaft End, which respectively corresponds, to be fixed on two free ends of bracket, the identical casing of coaxial package at least three in shaft, and adjacent two A rotating roller, the rotating roller are equipped between a casing together with shaft coaxial package.

Five casings of coaxial package in the shaft are equipped with a rotating roller, the rotation between two adjacent casings Roller together with shaft coaxial package, be close to the end face of the casing of respective side by the two sides of each rotating roller, is located at shaft The outer end face of the casing at both ends correspondence is tightly attached on bracket, and multiple rotating rollers constitute similar comb shape, rotating roller with shaft Shaft, which can hold down forward weeds, while front end rolls is tilted a certain angle, and passes through " comb teeth " rotating roller for stalk Longer weeds are combed, and weeds is made to expose root to a greater degree, are combed subsequent cutter convenient for roller and are cut.

The hand-held push rod is equipped with two reinforcing rods, the both ends of every reinforcing rod are separately fixed at hand-held push rod and branch On frame, increase the fastness and stability connected between hand-held push rod and bracket.

The free end of the hand-held push rod is equipped with rubber friction layer, and increasing friction force is convenient for the control of hand.

The two sides of plane where the cutter and hand-held push rod are located at bracket push hand-held push rod that can make cutter The weeds of close proximity to ground.

The principles of the present invention and use process:

Push entire weeder in careless rolls on the floor by hand-held push rod, multiple rotating rollers constitute similar comb with shaft Shape, rotating roller shaft while front end rolls, which can hold down forward weeds, to be tilted a certain angle, and is rotated by " comb teeth " Roller combs the longer weeds of stalk, so that weeds is turned forward to a greater degree and exposes root, roller during promotion It combs subsequent cutter to be forced to swing backward, the cutting shape (such as Fig. 1) when forming promotion forward is finally blocked by limit stop post to miscellaneous Grass is cut, and during then pulling back, cutter is swung to corresponding opposite direction, is finally blocked by the limit stop post of the other side It forms the cutting shape (such as Fig. 2) when pulling back backward to cut weeds again, guarantees weeding quality and efficiency, repeat above-mentioned mistake Journey.

The utility model cutter, which is hinged on bracket and limits its swing angle by limit stop post, obtains optimal cutting Angle, cutter is equipped with double cutting edge, and it can be according to pushing away, direction drawn to be swung accordingly, during reciprocal push-and-pull Cut weeds, and common hoe can only carry out cutting weeding when pulling back, and during pushing away bracket front end it is multiple Weeds can be carried out " combing in advance " by rotating roller before, so that weeds is turned forward as far as possible and exposed root convenient for cutter below Cutting, greatly improves the efficiency and quality of weeding.
