Description

A kind of weeder

Technical field

It the utility model is related to a kind of Simple weeding device.

Background technology

In agricultural and horticultural field, cleaning weeds are a hard works.Worked for the big weeding of workload, people Chemical pesticide weeding is generally used, can so cause serious environmental pollution or food-safety problem.Removed for workload is small Grass work, people are generally by the way of hand-lifting grass or reaping hook are mowed, and so work causes high effort for, and operating efficiency is low.

Utility model content

The problem of the utility model is that to solve existing weeding system or pollution environment, or job difficult, and efficiency is low, carries For a kind of weeder.

The utility model weeder includes outer barrel, inner cylinder, push rod, the first spring, upper cutting blade, lower cutting blade, folder Piece and second spring, outer barrel is cased with outside the inner cylinder, gap is left between outer barrel and inner cylinder, outer barrel can produce phase with inner cylinder To rotating, push rod is arranged on the inside of inner cylinder through the first spring, and gap is left between inner cylinder and push rod, and inner cylinder can with push rod Relative slip is produced, the bottom of inner cylinder is bulb, and the outside of bulb is symmetrical arranged under two panels close to one end of outer barrel cuts Blade, lower cutting blade are fixedly connected with bulb, and the positional symmetry of the outer lower end of outer barrel sets cutting blade in two panels, on Cutting blade is fixedly connected with outer barrel, and the vertical range of upper cutting blade and lower cutting blade is 1~2mm, and the bottom of push rod is Supporting part, the supporting part are circular cone build, and the bottom symmetrical of inner cylinder bulb is provided with two panels intermediate plate, is provided between two intermediate plates Two second springs, the bottom hinge connection of the intermediate plate and bulb, the upper end of push rod is provided with pusher grip, the upper end of inner cylinder Provided with inner cylinder handle, the upper end of outer barrel is provided with outer barrel handle.

The upper cutting blade is double-edged blade, and the lower cutting blade is double-edged blade.

The distance between described two second springs are more than the maximum gauge of support cross section.

The bulb is hollow structure so that bulb can be placed in the inside of bulb.

The height of the inner cylinder is 90~100cm.

The operation principle of the utility model device：

In use, the utility model weeder is inserted in soil, inner cylinder handle and outer barrel handle are rotated, makes outer barrel and interior Relative rotation is produced between cylinder, and then upper cutting blade and lower cutting blade are merged, plays a part of " scissors ", will be miscellaneous Grass is cut off.If the weeds that running into cut off can also take the utility model weeder to pull out.Concrete operations are：Weeding Person presses downwards pusher grip, the first spring-compressed, push rod slide downward, the supporting part of push rod bottom also slide downward simultaneously, Into in the gap between two panels intermediate plate so that two panels intermediate plate struts, and second spring expansion, intermediate plate then is inserted into weeds root Soil, pusher grip, the first recoil of spring are unclamped, push rod rises together with supporting part, and second spring resilience, two panels intermediate plate is second Tightened up in the presence of spring, clamp weeds, lifted weeder upwards, i.e., extract weeds.

The beneficial effects of the utility model：

The utility model weeder is simple in construction, easily operated, and weeder need not bend over or squat down, you can removes miscellaneous Grass.Cutting blade in the utility model device is double-edged blade, i.e., high in the cleavable weeds of both direction, weeding ratio. The utility model device weeding is thorough, can be with uprooting weed while the present apparatus is mowed, and weeding is clean, thorough, and herbicidal effect is good.
