Description

Earth digs throws the fire extinguishing go-cart

Technical field

The utility model belongs to cuts the earth and fire-fighting machine, particularly a kind of with the forest of soil to catching fire, the digging machine that the mountain forest that especially catches fire is put out a fire.

Background technology

Forest fire mostly occurred in the high thing of wind dry season, and its loss that causes may be very serious, not only burns a large amount of forests, causes the pollution of air and environment, even can cause personnel's injures and deaths.More trouble is, in forest, and particularly in the mountain forest during breaking out of fire, the particularly difficulty of work of putting out a fire to save life and property.At present, China is in the mountain forest fire extinguishing, the following several method of main employing: the one, concentrate great amount of manpower, with mop or the fire extinguishing of the original tools such as branch cut down temporarily, the method weak point is that fire-fighting efficiency is low, and often the fire on comburant surface has been extinguished, but does not extinguish fully this comburant inside, in case obtain the support of oxygen in the air, resume combustion easily.The 2nd, adopt the fire extinguisher bomb fire extinguishing, utilize the cold mist or the things such as powder that scatters or carbon dioxide that cause after the fire extinguisher bomb blast, with the comburant secluding air and make its rapid refrigeration and extinguish, the weak point of this kind method is that the area that acted on of each piece fire extinguisher bomb is less, and expense is higher.The 3rd, with the wind-force fire extinguishing, this kind method is with strong wind fire to be blown out, and is characterized in that necessary application is proper, otherwise the face diffusion that can cause on the contrary catching fire.The 4th, use foam fire-fighting, the required foam consumption of this method is too big, and expense is too high, and when the area that especially catches fire was especially big, required foam was difficult to guarantee.The 5th, the most frequently used and effective method, it is the method that water sprays, high-end to forest particularly, additive method often is difficult to reach target, the mountain forest place that its defective is to catch fire usually, be the place far apart from the water source, it is very difficult to fetch water, and the supply rate of water often is unable to catch up with the rate of propagation of the intensity of a fire.In addition, in order to help fire extinguishing, prevent fire spreading, need to excavate the isolation strip more, but for brushfire, the place on steeper mountain forest area of physical features and no road particularly, big machineries such as bull-dozer are difficult to arrive the ground that catches fire, and the excavation isolation strip is undertaken by manpower fully, wastes time and energy, the isolation strip is not dug as yet often, in face of fire burns again.And up to now, be not used as yet with native method for extinguishing fire; And the equipment of cutting the earth mostly is earthmover again at present, generally by vehicle frame, and driver's cabin, engine, clutch, hydraulic arm, turntable, pick bucket, control stick, wheel or crawler belt etc. are partly formed, during operation of power excavators, under pilot control, the power of engine is after gearbox is exported, and driving hydraulic arm manipulation pick bucket fetches earth or be native, because of it has huger volume, be only applicable to comparatively openly, relatively flat and place that Lu Ketong arranged be with the excavation irrigation canals and ditches, or be used for engineering construction.When being used for the mountain forest fire extinguishing, only be used to have Lu Ketong and place in easy flights, the isolation strip that cooperates the earth mover excavation to prevent fire spreading.And be applicable to the shoveling fire-extinguishing apparatus of brushfire, not seeing so far had report and used.

Summary of the invention

The purpose of this utility model, be at forest fire, especially brushfire, a kind of small-sized machine of the fire extinguishing of can fetching earth on the spot is provided, the fire-fighting machine that is provided is provided, can save water for fire extinguishing, chemical foam, resources such as fire extinguisher bomb, can bring into easily large-scalely push away, the area that catches fire that digging machine cannot or hardly arrive, and when the limit is with the soil fire extinguishing, can also promptly excavate out the isolation strip, prevent fire spreading, shorten the burning time of fire, with loss that reduces the forest burning and the environmental pollution that is caused.

Guiding theory of the present utility model is, since in the place that trees grow into forest, a large amount of earth must be arranged, and these earth turned over dig, and throws to the thing that catches fire and hits fire extinguishing, and soil is covered on the comburant, makes itself and air isolated, just can reach the purpose that fire is extinguished.

The purpose of this utility model is achieved in that earth digs throwing fire extinguishing go-cart, comprises engine, gearbox, and actuating unit, vehicle frame, wheel, this go-cart also comprises vehicle wheel frame, shoveling wheel apparatus, vehicle wheel frame elevation and subsidence regulating device; Described shoveling wheel apparatus comprises the wheel of cutting the earth, the wheel wheel shaft of cutting the earth, shoveling wheel bearing; Described vehicle wheel frame comprises that wheel hub is with vertical and be welded on lifting arm on the wheel hub with it; Close its position: pushing hands is positioned at the vehicle frame upper end, and be the part of vehicle frame, the shoveling wheel apparatus is installed on the bottom foreleg end bearing seat of vehicle frame by the shoveling wheel bearing, vehicle wheel frame is installed on the bottom back leg of vehicle frame by the wheel elevation and subsidence regulating device, wheel is installed on the wheel hub by wheel bearing, and engine and gearbox are fixed on the middle part of vehicle frame from top to bottom successively; Its annexation is: for key is connected, the power of engine is exported through output shaft of gear-box between shoveling wheel wheel shaft and shoveling wheel, and wheel shaft is taken turns in the shoveling that is delivered to the shoveling wheel apparatus through actuating unit, and drive is cut the earth and taken turns rotation.

Actuating unit described in the utility model is belt drive unit or sprocket transmission device or gear drive.Described wheel elevation and subsidence regulating device is eccentric wheel locking device or rack-and-pinion device.Be connected for spline between shoveling wheel wheel shaft and shoveling wheel.Throw above the soil wheel digging, on the vehicle frame of the front of power set, also be provided with a dashboard.

The beneficial effects of the utility model are: adopt machinery provided by the invention, to the ground comburant and apart from ground not high comburant, bottom as bushes and trunk, all can extinguish the blaze with soil effectively, save the water or the foam of coming out, be used for fire extinguishing is sprayed on trunk top, just can reduce the use of resources such as foam, water, fire extinguisher bomb, saved these resources.When digging throwing soil, just dig out the isolation strip, saved manpower and time.Also, save time, can reduce the quantity of burning of forest, reduce the air pollution that is caused because of gathering materials on the spot.
