Abstract

Provided is an acute-angle-tooth knife type handheld land preparation agricultural implement. An turnover edge is manufactured at the periphery of the upper portion of an acute-angle-tooth knife of a plate body from the reverse side to the obverse side, the acute-angle-tooth knife is manufactured at the lower end of the plate body, slope-angle edges are manufactured on the reverse sides of the two sides of the acute-angle-tooth knife respectively, a holding base is fixed to the upper portion of the plate body, and a handle is installed in the holding base. The acute-angle-tooth knife type handheld land preparation agricultural implement can be easily inserted into hard soil when used; due to the fact that the portions, on the reverse sides of the two sides of the acute-angle-tooth knife are ground to form slop angles, the sharp knife bodies are formed; when the acute-angle-tooth knife type handheld land preparation agricultural implement is used, small stones are naturally sprung to rotate to the portion behind the acute-angle-tooth knife type handheld land preparation agricultural implement under the action of tilting force of knife angles due to forward stress, the acute-angle-tooth knife type handheld land preparation agricultural implement cannot easily collide with the stones when in operation, and has multiple purposes such as harrowing, ditching and ridging, especially in an operation area with a large amount of weeds and strong weeds, due to the fact that the sharp knife bodies are arranged on the two sides of each tooth angle respectively, and can rapidly cut off the weeds and roots, and high weeds can be mowed in a segmented mode; the acute-angle-tooth knife type handheld land preparation agricultural implement is light in self weight, the angle knife bodies are sharp, the width of the ground with which the acute-angle-tooth knife type handheld land preparation agricultural implement makes contact is large, the operation speed is high, time and labor are saved, and the acute-angle-tooth knife type handheld land preparation agricultural implement is mostly applicable to persons who are advanced in age and poor in health and female labor force.

Description

The hand-held preparation tool of acute angle serrated knife formula

Technical field

The present invention relates to a kind of agricultural tool, relate in particular to the hand-held preparation tool of a kind of multipurpose acute angle serrated knife formula.

Background technology

China is large agricultural country, and along with Agricultural Tech Advance, it is trend of the times that mechanization is cultivated.At present, mechanization is ploughed and can only be used for operation on level land that area is larger, and trench digging, weeding, ridging, the tune ditch of the various crops of planting under mountain area, hillside fields, little plot, ditch both sides, fruit tree garden, greening gardens and some Special Geographic conditions, sow, plough, take off soil, make the multi-mode operations such as the ridge, be difficult to all complete by mechanical work.And in rural area, large quantities of Farmer Labors in Cities is done manual work, remaining majority is old labour and women, these people's physical efficiencys are poor, and the preparation tool using is the hand-held farm implements such as crotch pick, valley hoe that hand down over the past thousands of years, use this conventional tool to carry out tillage operation, not only effort, and operating efficiency is extremely low, farming season very easily by mistake.In addition, these instrument purposes are single, long-term placement after using, and very easily corrosion, affects service life.

Not yet there is at present a tool multiplex, can complete trench digging, weeding, ridging, tune ditch, sow, plough, take off soil, make the saving time of the multi-mode operations such as the ridge, labour-saving manpower agricultural tools.

Summary of the invention

The problem existing for manpower agricultural tools in current agricultural production, the invention provides an a kind of tool multiplex, can complete trench digging, weeding, ridging, tune ditch, sow, plough, take off soil, make the multi-mode operations such as the ridge, for vegetables, medicinal material, orchard, paddy field Ji little plot operation provide easy to use, operating efficiency is high and labour-saving farm implements.

Addressing the above problem taked technical measures is:

The hand-held preparation tool of a kind of acute angle serrated knife formula, it is characterized in that: at the plate body periphery on acute angle serrated knife 3 tops of plate body 1, be shaped with flange 2 to front by the back side, be shaped with acute angle serrated knife 3 in the bottom of plate body 1, the back side, both sides at acute angle serrated knife 3 is shaped with slope angle blade, in the fixing tube base 4 in the upper bottom along flange 2 of plate body 1, in tube base 4, be equipped with hand-held 5.

The quantity of acute angle serrated knife 3 is 2 or 3 or 4 or 5.

Beneficial effect of the present invention: the present invention adopts acute angle serrated knife formula, in use to harder soil easily frustrate into, become sharp knife in the back side of acute angle serrated knife both sides polishing slope angle, have certain angle, when use, by stressed forward, finger stone is difficult for colliding stone after naturally being forwarded to by bullet under the tilting force effect of nose angle when operation, have in the time taking off the multi-mode operations such as ground, ditching, ridging, can reduce the anti-impact of stone to instrument as far as possible, alleviate people's physical demands simultaneously.More, more strong to weeds especially operation area, because the back side, acute angle tooth both sides is with scraper, produces certain tilting force firmly time, it can, fast disconnected to weeds and undercut, cradle top grass sectional.Instrument deadweight is light, angle knife edge profit, and face width contiguously, the operation speed of getting up is fast, saves time, laborsaving, and the most applicable old and womenpower uses.
