Description
Technical field
The utility model relates to a kind of high-power bulldozer pressurized driving cap, belongs to the one adopted on bulldozer novel driver's cabin practical technique field, is improved under being specially adapted to bad environments working condition to driver's operation environment.
Background technology
Because the suitable environment of high-power bulldozer is comparatively severe, a large amount of dusts and other pernicious gas is there is in air, the sealing of tradition driver's cabin is poor, there is the phenomenon into ash, air inlet, in use inevitably there are the dust in air and other pernicious gas to be entered by the gap of driver's cabin connecting portion, accumulate over a long period and can cause great harm to the physical and mental health of driver.
Summary of the invention
The purpose of this utility model provide for weak point existing in above-mentioned prior art just a kind of be specially adapted to bad environments working condition under the high-power bulldozer pressurized driving cap that can be improved driver's operation environment.
The purpose of this utility model realizes by following technique measures:
High-power bulldozer pressurized driving cap of the present utility model comprises driver's cabin, forms excellent sealing isolate between the interior space of described driver's cabin and ambient atmosphere by encapsulant; And the interior space of described driver's cabin is communicated with air by the pressurized air input pipe be connected with supercharging device, air filter successively.
Fluid sealant is coated with between the skylight of driver's cabin described in the utility model and ceiling installed surface, between outer ceiling and cab framework, sponge sealing strip is installed, control stick, controlled pedal and junction, floor use the sealing of bellow seal cover, bellow seal cover bottom is connected with floor by pressing plate, and the overlapping area strengthened between the two, line was used to overlap sealing between electrical equipment wiring harness and driver's cabin connect, and wire harness its outside winding sealing joint strip when passing through line cover, air-conditioner pipe is connected two ends and arranges sebific duct sealing mat with floor.
Supercharging device described in the utility model is automatically controlled blast fan, regulates air output by switch control rule blower speed in driver's cabin, and then adjustment enters driver's cabin inner air pressure; Electrical equipment in described driver's cabin, braking wire harness adopt connected structure, and air-conditioning duct adopts direct-connected two ends hermetically-sealed construction.
Operating principle of the present utility model is following and beneficial effect is as follows:
The pressurization system that the utility model can utilize supercharging device, air filter to form by the outdoor air filtered through air filter by sending in driver's cabin after supercharging device supercharging, the minimum efficiency of strainer, more than 96%, ensure that the air quality entering driver's cabin.Under driver's cabin seals good situation, wherein portion of air can be retained in driver's cabin, another part air is gone out by the micro gap seepage on door and window, top cover and floor, and through pressure process after a while, the air pressure in driver's cabin is greater than external atmosphere pressure gradually.Along with the increase of room pressure, the air capacity discharged by gap also can correspondingly be increased, in this course, enter the state that air capacity in driver's cabin and the air capacity that discharges can reach a relative equilibrium gradually, the pressure differential inside and outside driver's cabin also can remain on a metastable numerical value.Because the pressure in driver's cabin is higher than external atmosphere pressure all the time, all the time the high pressure draught outwards blown is had by the micro gap of driver's cabin, pressurization system air intake has air filter, the gas that dust or noxious material are contained in such external world would not directly enter in driver's cabin, ensure that the clean and health in driver's cabin, be beneficial to the physical and mental health of driver.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, high-power bulldozer pressurized driving cap of the present utility model comprises driver's cabin 1, fluid sealant is coated with between the skylight of described driver's cabin 1 and ceiling installed surface, between outer ceiling and cab framework, sponge sealing strip is installed, the size of reasonable Arrangement doorframe, window frame reduces the gap between glass and skeleton, strengthen the compress variation of weather strip, increase the area of glass and skeleton lap; Control stick, controlled pedal and junction, floor use the sealing of bellow seal cover, bellow seal cover bottom is connected with floor by pressing plate, and the overlapping area strengthened between the two, line was used to overlap sealing between electrical equipment wiring harness and driver's cabin connect, and wire harness its outside winding sealing joint strip when passing through line cover, ensure to be tight fit therebetween; Air-conditioner pipe is connected two ends with floor increase sebific duct sealing mat, ensures the tight fit at two ends, make to form excellent sealing between the interior space of driver's cabin 1 and ambient atmosphere and isolate; The pressurized air input pipe be connected with supercharging device 2, air filter 3 is successively provided with in the bottom of described driver's cabin 1.
Supercharging device 2 described in the utility model is automatically controlled blast fan, regulates air output by switch control rule blower speed in driver's cabin, and then adjustment enters driver's cabin inner air pressure; Electrical equipment in described driver's cabin 1, braking wire harness adopt connected structure, and air-conditioning duct adopts direct-connected two ends hermetically-sealed construction.
Under the utility model ensures the prerequisite of driver's cabin good seal by above measure, first outside air is filtered by the air filter of pressurization system, and the minimum efficiency of strainer, more than 96%, ensure that the air quality entering driver's cabin.Then the air after filtering increases the pressure carrying air in driver's cabin by supercharging device, the air after pressurization constantly enters in driver's cabin.Through pressure process after a while, driver's cabin inner air pressure can be greater than external atmosphere pressure gradually.After the air capacity entered in driver's cabin and the state being reached a relative equilibrium by the air capacity that gap is discharged, the pressure differential inside and outside driver's cabin also can keep the numerical value of a relative constancy.So just remain the high pressure draught outwards blown by the micro gap of driver's cabin, thus ensure that the extraneous gas containing dust or noxious material can not directly enter in driver's cabin, ensure that driver is in a working environment cleaned with health, ensure the physical and mental health of driver.
