Description
Technical field
This utility model is related to agricultural machinery technological field and in particular to the drive mechanism of power-operated mower.
Background technology
Hay mover be a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it is by cutterhead, electromotor, road wheel, OK
Walk mechanism, blade, handrail, control section composition.Cutterhead is contained on road wheel, equipped with electromotor on cutterhead, the output of electromotor
Equipped with blade on axle, blade utilizes the high-speed rotation of electromotor to improve in terms of speed a lot, saves the operation of weeding workman
Time, decrease substantial amounts of human resourcess.
Weeder development promotes mechanization of agriculture, improves work efficiency, improves agricultural production efficiency, such a at us
Large agricultural country is particularly important, and hay mover, as the instrument of important role in agricultural production, has to the yield of crops
And directly affect most, its invention is a much progress of human civilization.Hay mover be a kind of for cutting the grass on a lawn, the machine of vegetation etc.
Tool instrument, have diesel engine and gasoline engine point.It is by cutterhead, electromotor, road wheel, walking mechanism, blade, handrail, control
Form Deng part.Blade is greatly improved using the high-speed rotation output speed of electromotor, saves the activity duration of weeding workman,
Decrease substantial amounts of human resourcess.In the country of Mechanization of animal husbandry high development, the research of Novel grass cutter just towards at a high speed,
The direction of energy-conservation is developed.
Generally, when needing to shut down in mowing machine operation way, even if user cuts off the electricity supply, rotating blade is because of inertia
The effect of power still can run up a period of time it is impossible to meet the requirement of safety criterion, even can cause personal injury when serious.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, provides that a kind of structure is simple, design is closed
Reason, the drive mechanism of power-operated mower easy to use.
For achieving the above object, the technical solution adopted in the utility model is：It comprises rotating blade, polywedge bet, bearing,
Series excited machine, driving wheel, brake disc, brake block, stop nut；Series excited machine is provided with described bearing, series excited machine
Output shaft is connected by polywedge bet with driving wheel, and the power transmission shaft of driving wheel is provided with rotating blade；On described series excited machine
Be provided with brake disc, brake disc is connected with bearing by screw, the output shaft cooperation of brake block and series excited machine, and brake block with
Pass through stop nut axial restraint between the output shaft of series excited machine.
Preferably, described brake block is butterfly brake block.
Preferably, described brake disc and brake block are made using high intensity, High wear-resistant steel material.
During this utility model operation, deposited by stop nut and butterfly brake block natural resiliency between brake block and brake disc
In pretightning force, now, series excited machine remains static；When artificially stirring rotor, to overcome and be caused due to pretightning force
Frictional force, it appears especially painstaking；After series excited machine starts and reaches certain rotating speed, on brake block, often a piece of blade all can produce
The very big centrifugal force of life, when overcoming stiction and the self gravitation between brake block and brake disc enough when centrifugal force, brake
Piece will depart from brake disc in vertical direction, and now frictional force is no longer done work；When power source, with the fall of motor speed
Low, the component of centrifugal force is less than pretightning force, and brake block returns to initial position again, and now frictional force can produce huge resistance,
Stop rotor due to remaining in operation that inertia force produces.Frictional force overcomes inertia force to do work, brake disc and brake block it
Between produce substantial amounts of heat energy so that motor speed is rapidly reduced to 0, now frictional force becomes brake force, due to depositing of brake force
Greatly reducing the time of series excited machine stopping brake.
After said structure, what this utility model produced has the beneficial effect that：Power-operated mower described in the utility model
Drive mechanism, quickly stop operating after cutting off the electricity supply, using safety, personal injury will not be caused to user, this practicality is new
Type has the advantages that structure is simple, setting is reasonable, low manufacture cost.
Brief description
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the structure chart of this utility model series excited machine.
Description of reference numerals：Rotating blade 1, polywedge bet 2, bearing 3, series excited machine 4, driving wheel 5, brake disc 6, brake block
7th, stop nut 8.
Specific embodiment
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before not paying creative labor
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Referring to as shown in Fig. 1 Fig. 2, this specific embodiment adopts the following technical scheme that：It comprises rotating blade 1,
Polywedge bet 2, bearing 3, series excited machine 4, driving wheel 5, brake disc 6, brake block 7, stop nut 8；It is provided with described bearing 3
Series excited machine 4, the output shaft of series excited machine 4 is connected by polywedge bet 2 with driving wheel 5, and the power transmission shaft of driving wheel 5 is provided with rotation
Rotor piece 1；Brake disc 6 is provided with described series excited machine 4, brake disc 6 is connected with bearing 3 by screw, brake block 7 and string
The output shaft cooperation of sharp motor 4, and between the output shaft of brake block 7 and series excited machine 4, pass through stop nut 8 axial restraint.
Preferably, described brake block 7 is butterfly brake block.
