Abstract
A cam telescopic driving wheel is provided. An expansion port is arranged on the round main driving wheel of the utility model, and an expansion blade is arranged inside the round main driving wheel. An expansion body consists of the expansion blade, a blade connecting shaft, a contact pressure plate and a compression spring. The contact pressure plate is always contacted with the contour of a cam which is fixedly arranged on a machine body through a fixing shaft. A bearing cover is movably connected with a sealing cover through a bearing and the fixing shaft. The main driving wheel is in key coupling with a driving shaft, and the driving shaft is connected with a host transmission system. The utility model is characterized in good driving property in mud paddy fields without carrying mud and grass, low power consumption, large driving moment, high work efficiency, no sinking and slipping when working in mud paddy fields, simple structure, reliable performance and wide application, which is suitable to be used as the driving wheel on combine harvesters, tillage machines, transplanters and various agricultural machineries.
Description
Technical field
A kind of field machine product, the cam-retractable drive wheel, a kind of wide accommodation is suitable for doing on the field machine product that muddy water field drive wheel is used especially.
Background technology
At present both at home and abroad the travel driving unit that generally uses on the agricultural machinery product is divided into crawler type and wheeled two kinds, the crawler type device is adapted to northern dry land and uses, but because cost height, from great, quick abrasion, power consumption height, inefficiency, the defective that folder mud band grass is arranged, and the surface, field is compacted, thereby be unwell to southern mountain area and the walking operation of high-land muddy water field.Though wheeled devices is from heavy and light, simple in structure, but because its external diameter size and drive vane sponson remain constant, make this wheel when the walking operation of muddy water field, the defective of ubiquity folder mud band grass, work-hours is long slightly, has all sticked the mud grass in the space of wheel outer rim two sponsons, the mud grass is along with wheel rolls, drive wheel deadweight is increased, and consumption of power increases, cause driving engine in the muddy water field phenomenon of flame-out " deadlock ", in addition because the embedded bigger mud grass of viscosity of having expired in space, each drive vane overhang is reduced, and the forfeiture propulsive effort causes the original place to skid, sink gradually, can't normal operation.In a word, above travel driving unit ubiquity folder mud band grass easily stops up, power consumption is big, and efficient is low, weak points such as muddy water field walking driveability difference.
Summary of the invention
The purpose of this utility model provides a kind of for the cam-retractable drive wheel that uses on the field machine, and it is good to accomplish at muddy water field operation driveability, does not press from both sides mud band grass, and drive torque is big, and consumption of power is little, high efficiency.
The core of technical scheme is that the drive wheel on the existing field machine (as reaper, harvesting and tillage machine, rice transplanter) is improved, change the fixing overhanging drive vane of circular wheel into telescopic drive vane, blade stretches out wheel rim in position, advancing drive angle section, produce bigger drive torque, after having crossed before driving angle section, blade in the retraction wheel, has been avoided folder mud band grass and consumed power gradually.The area size of its overhang can determine the drive torque value, can design its overhang according to different facility needs, also can make adjustable.
This mechanism is made up of inner, middle and outer layer three parts, and internal layer is a cam, is installed on the anchor shaft, centre portion is flexible vane group zoarium, comprise flexible blade, compression spring, contact pressing plate, blade adapter shaft etc., skin is main drive wheel and seal cover cap, and bearing play supporting role.
Principle of work is as follows: rotary motive power is from driving the rotating shaft input, the drive main drive wheel rotates, main drive wheel drives flexible blade rotation, flexible blade, contact pressing plate and blade adapter shaft fabricate block are under the effect of compression spring elastic force, all the time keep closed contact with cam face, guarantee telescopic process realization smoothly in rotation, when main drive wheel rotates, flexible blade can be realized fore and aft motion according to the outline line shape of cam, flexible blade overhang maximum when the preceding half-angle of wheel turns requires the large driving force square will be in the time of will turning over vertical central plane, in order not press from both sides mud band grass, flexible blade is withdrawn gradually, until in the flexible mouth of wheel of all withdrawing.
Compared with the prior art, characteristics of the present utility model are that muddy water field driveability is good, do not press from both sides mud band grass, consumption of power is little, and is non-slip, and drive torque is big, high efficiency, because mechanism is simple, sealing property is better simultaneously, buoyancy increases, sink when having avoided working in the muddy water field, drive torque increases, and can make adjustable mechanism, be particularly suitable on combination machine, doing drive wheel usefulness, on the small-sized and miniature wheeled harvester of southern widespread usage, more can bring into play unique effect.The utility model also can be applicable to do on the field machine of various muddy water field operations such as harvesting and tillage machine, trac., rice transplanter actuating device and uses.

The specific embodiment
As shown in the figure, the utility model comprises main drive wheel 7, drives rotating shaft 8, and both link with flat key 9.Have flexible mouthful 13 on the main drive wheel 7, flexible blade 5 is flexible in flexible mouthful 13 under the effect of elastic force, and elastic force produces and fore and aft motion complements each other to form by taper compression spring 6, the shape of cam 10 and the links such as rotation of main drive wheel 7.Contact pressing plate 11 forms a whole with blade adapter shaft 12, flexible blade 5, taper compression spring 6 is contained on the blade adapter shaft 12, the miner diameter end of taper compression spring 6 contacts with the internal circular surfaces of main drive wheel 7, and bigger diameter end applies pressure on the contact pressing plate 11, makes it to remain with cam 10 to contact.Cam 10 and anchor shaft 1 are for being fixedly connected, the connecting mode of anchor shaft 1 and main frame and drive rotating shaft 8 and main frame driving system connecting mode and can determine according to different mechanical types and type, inner seal lid 4 and bearing cap shim 2 adopt Bolt Connection, in block bearing 3 is arranged, inner seal lid 4 and main drive wheel 7 adopt Bolt Connection.
Its principle of work and working process are: rotary motive power is from driving rotating shaft 8 inputs, driving main drive wheel 7 rotates, main drive wheel 7 drives flexible blade 5 and rotates, simultaneously because the effect of compression spring 6 elastic forces, when main drive wheel 7 rotates, flexible blade 5 can be realized fore and aft motion according to the outline line shape of cam 10, stretch in the advance angle position section that requires to produce drive torque, and then shrink back gradually, desliming automatically in rotation process, avoid pressing from both sides mud band grass, flexible blade 5 can all be withdrawn in flexible mouthful 13, can decide the drive torque value by the area size of regulating overhang.
