Abstract

The invention provides a mower which comprises a cutting mechanism, a steering mechanism, a height adjustment mechanism, a motor, a protecting cover, a grass collecting container, wheels and a push handle. The cutting mechanism is coupled to the motor, a height adjustment component is communicated with a motor adjusting component, and a cutter of the cutting mechanism is of an impeller structure composed of a plurality of blades. The mower has the advantages that the problems of big noise, environmental pollution and low mowing efficiency and the like in the prior art can be solved; compared with traditional mowers, the mower not only is light in weight, but also solves the problem of battery driving capability insufficiency, and the service life is prolonged.

Description

A kind of mower

Technical field

The invention belongs to mower field, especially relates to a kind of cutting knife of mower.

Background technology

Rotary mower has the housing of downwardly facing opening, receives blade is housed, thereby blade rotation can be mowed in housing.What in such mower, have has a mowing collection mode.The mower with mowing collection mode is received the grass of cutting off with blade the mowing that installs to sack etc. and is received in dress body when mowing, thereby can all remove mowing, thereby the completeness of mowing work is higher, be often used in golf course, greenbelt small-sized lawn etc.Yet the mowing efficiency of cutting knife can not be fully up to expectations.

Summary of the invention

The problem that the invention will solve is to provide a kind of mower, especially introduces its Novel cutting machine structure.

For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of mower, comprises cutting mechanism, steering mechanism, height adjustment mechanism, motor, guard shield, collects careless container, wheel and push away handle, described cutting mechanism is couple to described motor, and described height adjustment means is communicated with described motor adjustment means, the impeller type structure of the cutting knife of described cutting mechanism for being comprised of multi-disc blade.

Further, the blade number of described impeller type cutting knife is no less than three.

Further, the blade face of described blade is angled with ground when mounted, and described angle is less than 90 °.

Advantage and good effect that the invention has are: can solve noise large, environmental pollution, the problem that the prior aries such as mowing efficiency is low exist, compare with traditional mower that not only to have obtained weight light and handy, also solved the problem of battery-operated scarce capacity, the beneficial effect increasing the service life.

Embodiment

As shown in Figure 1 and Figure 2, the invention is a kind of mower, comprises cutting knife 5, steering spindle 4, height regulating shaft 6, motor 1, guard shield 2, collection straw bag 8, bucker 7, wheel 3 and push rod 9 and control handle 10, described cutting knife is couple on described motor, described height adjustment means is communicated with described motor adjustment means, the impeller type structure of the cutting knife of described cutting mechanism for being comprised of multi-disc blade.

The blade number of described impeller type cutting knife is no less than three, is illustrated in figure 1 the cutter of four blades.Can select according to lawn density degree the cutting knife of different sheet numbers.The blade face of described blade is angled with ground when mounted, and described angle is less than 90 °, and cutting effect is better like this.

The course of work of this example: the drive motors of mower is arranged in lower house snail-shaped cavity, is fastenedly connected by motor pad installation screw and lower house; In snail-shaped cavity, in order to increase the width of mowing, adopt the technology of four leaf blades, at motor axial location, blade is installed, blade, by mounting flange, is installed screw and drive motors and is fastenedly connected, and the lawn of having cut grass looks very smooth.Can also expand to multitool and install, its installation method and architectural feature are identical with hilted broadsword.A movable motor and electrical control mechanism are also housed in lower house; Fuselage bottom is equipped with four walking wheels, for mower, automatically walk, user can promote mower very easily, realize mowing function, and produce thus enough large whirlwind disconnected grass is blown into and is collected in careless container, to realize the disconnected careless object of automatic collection, raise the lid of upper casing and pull, can battery be inserted in mower or extract battery.Two adjusting levers before and after mower both sides have, for adjusting mowing height.Above-mentioned handle is Foldable-type handle, microswitch is installed on handle, mowing switch, automatic walking switch, be used for controlling the mowing function and automatic walking function of mower, handle is divided into upper and lower two parts, by four CARRIAGE BOLTSs, it is interconnected, during mowing, handle is installed and fuselage, then pack two lithium batteries into, key switch is screwed into " ON " state, hear the buzzer sound that " ticks ", and LED light is once bright, represents that mower starts normal operation, treat straw bag full grass automatically, complete mowing is closed key switch and is put OFF gear.Unclamp four CARRIAGE BOLTSs, handle is folded up and is placed on fuselage, can conveniently take by its carrying and storage.

If press microswitch in mowing process, circuit working, has at this moment only started mowing motor, and movable motor is not worked automatically.Now have by Manual-pushing mower advancement function; If press automatic walking switch, circuit working, at this moment only start automatic movable motor, and mowing motor is not worked.Now mower has automatic shift function; When mowing switch and automatic walking switch are all under open mode, press microswitch, control circuit work, first starts two mowing motors, then starts automatic movable motor, and finally both work simultaneously.Now mower grass also can be walked forward automatically, and after mower work a period of time, straw bag is full grass automatically, closes mower, cleaning weeds, complete or continuation mowing.

Electric control circuit comprises control chip, high power relay, and high-power start resistor, overcurrent sensing circuit, under-voltage body examination circuit, warning circuit, power lock switch, handle gauge tap, and control signal wire forms.Adopt single chip machine controlling circuit.By resistance reduced-voltage starting circuit and single-chip microcomputer main control circuit, formed.Get rid of the impact to battery of instantaneous large-current that normally used pulsewidth current limliting causes, effectively protected battery.Single-chip microcomputer governor circuit is monitored in real time to the running status of lithium ion battery.When starting switch startup being detected, single-chip microcomputer governor circuit sends instruction, connects resistance reduced-voltage starting circuit, starter motor running.Single-chip microcomputer main control circuit disable motor immediately when lithium ion battery or control circuit break down, and alarm shut-down operation, effectively improved the security performance of operation.Due in braking procedure without wearing and tearing, can extend the invention mower service life.

Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
