Description
Technical field
The invention belongs to small-sized machine design and manufacturing technology field, especially a kind of small-sized road ice-breaking snow removing machine.
Background technology
North of China most area, has the snowfall phase of 3 ~ 5 months every year, and road accumulated ice accumulated snow brings many difficulties to communications and transportation and people's daily life.In recent years the ice-breaking and snow removing machine of China has all had certain development in technology or manufacturing process, but the manufacturing and designing of most of ice-breaking and snow removing machine product biases toward large-scale, be mainly used in speedway, some important section and street in the national important main line of communication and city.Be applied in middle-size and small-size region as school, hospital, the local ice-breaking and snow removing machine such as real estate residential quarter is little, is almost in space state.Due to large-scale ice-breaking and snow removing machine complex structure, not easily to manufacture and cost is huge, the larger destruction to road pavement of energy consumption is comparatively serious, is difficult to be popularized use in middle-size and small-size region.So at present, domestic in school, hospital, middle-size and small-size region snow removing is many in real estate residential quarter etc. is completed by manual work, and its labour intensity is large, and operating efficiency is low.The snow removing equipment that import foreign country is advanced, cost is high and be not suitable for China's actual conditions; And carry out opening ice snow removing with other substitute machinery such as land leveller, then waste utility device and road pavement has destructiveness again.
Summary of the invention
The object of the invention is to design a kind of small-sized snow removing machine that opens ice help people and complete snow removing, raise labour efficiency and save labour, change domestic middle-size and small-size region in snow removing of opening ice, lacks this present situation mechanical.
Design scheme of the present invention is: small-sized road ice-breaking snow removing machine, it comprises hand propelled dolly, engine, power conversion mechanism, reducer, bent axle, bearing, connecting rod, rocking arm, perching knife, with hand propelled dolly for carrier, engine sends power and drives power conversion mechanism motion through reducer, and engine is diesel engine, gasoline engine, motor.Power conversion mechanism is crank and rocker mechanism, and crank and rocker mechanism bent axle, connecting rod, rocking arm, rolling bearing units and back shaft are formed.Crankshaft two end axle journal is arranged on rolling bearing units, big end is connected with crankshaft crank, small end of connecting rod is connected with rocking arm, and back shaft is arranged in rolling bearing units through rocking arm hole, and rocking arm can swing in certain angle around back shaft, back shaft has annular groove, realized the axial location of rocking arm by snap ring, bearing support is fixed by bolts on cart base plate, works as crank rotation, crankshaft installed is connected with rocking arm by connecting rod in rolling bearing units, and rocking arm does reciprocating swing with the rotation of bent axle; Hoe-type cutter head is installed in the extension of rocking arm, and cutter tooth acts directly on ice face.Reciprocation type swing with rocking bar is done movement in a curve and is constantly shoveled ice face of hitting (or degree of compaction snow face) by its fragmentation, and the perching knife number of work is identical with the crank throw number of bent axle.Bent axle, connecting rod derive from bent axle, connecting rod in automobile engine, determine the perching knife number of work according to its crank throw number.In order to reduce the validity to the damage on ground and the work of guarantee, a shock absorber installed by wheel, shock absorber is primarily of spring, plunger, plunger case, damping block composition.A shock absorber installed by wheel, when cutter tooth arrive minimum point time and earth surface, now set ground to a reaction force as infinitely great, certain displacement is had by the effect complete machine in the vertical direction of shock absorber, complete machine can be avoided by jack-up on the one hand, cutter tooth can be reduced to ground work on the other hand.
The utility model carries out in the design process of crank and rocker mechanism, its calculate main points and kinematic analysis of mechanisms as follows: ice and snow cutting resistance
; Kn: the uneven influence coefficient of cutter tooth (1 ~ 1.5); B1: effect cutter tooth width (300mm); H: ice-snow thickness (50mm); K0(70 ~ 130KPa) be resistance coefficient, it cuts off the necessary power of ice and snow layer that cross section equals 1 ㎡.F=1 × 130000 × 0.3 × 0.05=1950N; The perching knife work W=F × L=1950 × 0.176=343.2J(L that once does work represents perching knife operating distance); P=W/T=343.2/0.1=3.432kw; Bent axle does uniform rotation, and rocking arm does reciprocating speed change and swings, and its velocity variations characteristic is for first to have zero to accelerate to maximum speed, and then by most high deceleration to zero, acceleration and the speed in speed-change process of haveing suffered is all change.In order to can the snow removing effect that effectively opens ice be realized, get in design speed rocker arm maximum time cutter tooth start to contact ice face and start working, when speed rocker arm is zero by end-of-job time reverse.
Beneficial effect of the present invention: small-sized road ice-breaking snow removing machine of the present invention, has the features such as volume is little, mechanism is simple, cost is low, the damaging of less energy consumption, road pavement is little, pollution-free compared with the domestic existing snow removing equipment that opens ice.Most of component of machine such as engine, bogey, rolling bearing units, crankshaft-link rod etc. can directly commercially and cost is less.Although the present invention's structure is simple, do not lose that it is functional, different according to selected engine through testing this small-sized snow removing machine that opens ice, can the ice and snow face of broken different-thickness effectively.In ice and snow cleaning works so in the winter time, this machine can replace manpower to shovel hitting the accumulated snow of thin ice on road surface or compacting, greatly saves labour and improves efficiency.
The type of drive of complete machine can have multiple choices as required: employment first can be selected to push machine and advance, the advantage of this mode is can the pace of at random control machine, can more carefully finish the work, shortcoming is that to consume the physical Comparision of people slow; Secondly can install auxiliary drive engine to drive on original machine, this type of drive is more laborsaving and efficiency is high.
Feature and the advantage of small-sized road ice-breaking snow removing machine are: structure is simple, and manufacturing cost is lower; Energy consumption is little, little to the pollution of environment, and road pavement destructiveness is little; Operating efficiency is higher, little by ambient conditions restriction; Machine volume is less, and easy to operate and easy to be universal, market is extensive.
