Abstract
The utility model discloses a cooling device of a push-pull leaf machine engine, comprising a starter, a cooling impeller, a crank connecting rod group, a cylinder body, a fan impeller, a fan volute and a protection cover. The cooling device is characterized in that the starter is provided with a starting shell and the starting shell is connected with the protection cover to form a relatively sealed air cavity; the cooling impeller is arranged at the end part of a front shaft of the crank connecting rod group; the fan impeller is a double-faced blade impeller, is installed at the end part of a rear shaft and is located in the fan volute; a cooling wind source continuously passes through a gasoline engine heat radiation part under the common effects of the cooling impeller and the fan impeller; the cooled high-temperature wind is discharged from a wind discharging opening of the fan volute; the wind is forcedly cooled, so that the temperature of the engine is effectively reduced and the requirements of long-time work of the push-pull leaf machine engine are met.
Description
Technical field
The utility model relates to the portable dam technical field, particularly blows the cooling unit of Bothridium Machine motor.
Background technique
At present, the portable Bothridium Machine profile of blowing of use is small and exquisite, and power is big, and efficient is high; Easy to operate, use reliably, receive domestic and international client's welcome deeply, still; In order to realize the convenience of palm top, each enterprise all reduces the boundary dimension of hand-held tool as far as possible, therefore; The portable employed motor of Bothridium Machine that blows is placed in the narrow space as far as possible, and the friction because of each moving element of motor in use produces heat gradually, and the burning of fuel oil also discharges great amount of heat; Can cause the temperature of motor too high, in order to guarantee machine steady running for a long time, continuous cooling is absolutely necessary.Only adopt magneto rotor motor to be cooled off in the existing technical pattern as impeller; Because single impeller cools off, cooling air quantity is little, and very difficult solution works long hours and is prone to the problem that causes machine overheated; Therefore, be badly in need of a kind of device of very effective continuous cooling.
Summary of the invention
The utility model purpose provides a kind of cooling unit that blows the Bothridium Machine motor, and this device makes cooling air continuously pass motor by force through the acting in conjunction of two impellers, plays the effect of effective cooling.
The technological scheme that the utility model is taked is: a kind of cooling unit that blows the Bothridium Machine motor comprises starter, cooling wheel, crankshaft-link rod group, cylinder body, draught fan impeller, volute of blower, protective housing; It is characterized in that: starter is provided with the starting housing, and starting housing and protective housing are connected to form the air cavity of relative sealing, and the crankshaft-link rod group is provided with front axle, rear axle; Cooling wheel is installed in said preceding shaft end; Be arranged in air cavity, draught fan impeller is installed in said back shaft end, is arranged in volute of blower; Under the acting in conjunction of cooling wheel and draught fan impeller, cooling air passes the petrol engine heat-dissipating part and discharges through the volute of blower exhaust outlet.
Draught fan impeller is the impeller of two-sided blade, and it is radial that blade is.
Volute of blower is by intake grill and ventilated port two place's air intakes.
The beneficial effect of the utility model is that through the acting in conjunction of cooling wheel and draught fan impeller, the motor heating component can be cooled off fast, can effectively reduce the temperature of motor, satisfies the requirement of the long-time proper functioning of machine.

Sequence number explanation in the accompanying drawing: 1, big blade; 2, spiral case exhaust outlet; 3, cylinder body; 4, crankshaft-link rod group; 5, protective housing; 6, air cavity; 7, starter housing; 8, starter; 9, front axle; 10, cooling wheel; 11, ventilated port; 12, small leaf; 13, draught fan impeller; 14, volute of blower; 15, rear axle; 16, intake grill; 17, air intake flap.
Embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The engine cooling apparatus of the utility model is made up of starter 8 (starter housing 7), cooling wheel 10, crankshaft-link rod group 4 (front axle 9, rear axle 15), cylinder body 3, draught fan impeller 13 (big blade 1, small leaf 12), volute of blower 14 (spiral case exhaust outlet 2, ventilated port 11, intake grill 16), protective housing 5.
The concrete working procedure of the utility model: pulling starter 8, crankshaft-link rod group 4 drives cooling wheel 10 high speed rotating, and the cool air that the external world is fresh is drawn in the air cavity 6, thereby arrives engine radiating sheet place cooling petrol engine; Crankshaft-link rod group 4 drives draught fan impeller 13 high speed rotating simultaneously, under the effect of small leaf 12, is got in the volute of blower 14 by ventilated port 11 through cooled high temperature air, discharges from spiral case exhaust outlet 2 in the lump with big blade 1 rotation inhaled air.
Through the acting in conjunction of cooling wheel 10 and draught fan impeller 13, blow Bothridium Machine and suck extraneous fresh cool air continuously, during cool air process engine hot parts motor is forced cooling, cooled high temperature gas flow is discharged through spiral case exhaust outlet 2; Because draught fan impeller 13 is two-sided blade impeller, has further increased the admission velocity and the inlet of cooling air, has strengthened the cooling effect to motor greatly, has satisfied the usage requirement of blowing Bothridium Machine.
