The coal pushing device is characterized in that the power device is a manual gear speed reduction device. The manual coal pushing device adopts the manual gear speed reduction device as a power source for carrying out coal feeding operation for molded coal boilers. The manual coal pushing device has the advantages of saving equipment cost of power-driven coal feeding devices, providing simple structure, convenient operation and less labor intensity, being applicable to medium and the small sized molded coal boilers.
Description
Technical field
The utility model relates to a kind of device for coal that advances of molded coal boiler, is specially a kind ofly to advance device for coal for manually operated molded coal boiler.
Background technology
In order to improve environment, reduce the pollution of coal-burning boiler to environment in recent years, the domestic coal-fired boiler reform of carrying forward vigorously is promoted and is adopted molded coal boiler.Corresponding boiler advances the coal measures system and also transforms.As Chinese patent 03203104.1 disclosed a kind of the molded coal boiler of chimney arch " the configuration accumulation of heat ignite ", moulded coal wherein advances assembly to constitute the two point pushing mechanism by belt pulley, decelerator, two gears, two tooth bars and two rack frames assemblings.This moulded coal propulsive mechanism is applicable to large-scale molded coal boiler, for medium small boiler especially miniature boiler and incompatible.Existing molded coal boiler advances device for coal provides power by motor mostly, though it is easy to use, has alleviated labour intensity, but for miniature boiler, because its briquet negligible amounts, labour intensity is little, increases the electronic device for coal that pushes away of a cover and takies relatively large equipment cost.Chinese patent 91214427.0 discloses a kind of " the manual coal supply apparatus of moulded coal ", and it adopts handle rotating screw bolt device, and then the coal-pushing rod of lead-screw front portion moves forward and backward, and realizes pushing away the purpose of coal.This apparatus structure is simple, but operation is very inconvenient, and labour intensity is big, and is slow in one's movements, inefficiency.
Summary of the invention
The deficiency that the utility model exists at above-mentioned prior art, design a kind of hand and pushed away device for coal, adopt geared system to realize pushing away the coal operation, solved the unnecessary electronic device for coal that pushes away of existing middle-size and small-size molded coal boiler configuration, increased the deficiency of equipment cost significantly, overcome simultaneously that existing manually to push away device for coal labour intensity big, the defective that operating efficiency is not high.
A kind of hand of the present utility model pushes away device for coal, comprises profile modified gear and the spur rack that mates with profile modified gear, and described spur rack links to each other with power set by a profile modified gear axle with profile modified gear, and described power set are a manual gear deceleration device.
Described hand pushes away device for coal, wherein said manual gear deceleration device comprises driving gear shaft, gear wheel with the driving gear engagement, in the centre bore of gear wheel, be fixed with Large Gear Shaft During, the profile modified gear axle is connected with Large Gear Shaft During by connecting bushing, is fixed with rocking arm and handle in the outer end of driving gear shaft.
Described hand pushes away device for coal, and a supporting seat is arranged, and the profile modified gear axle joins by the axis hole and the connecting bushing on supporting seat top, and the bottom of supporting seat is fixed with a roller shaft, and the roller shaft outside has roller housing to be used for support spur rack.
Described hand pushes away device for coal, and the driving gear wherein and the gear ratio of gear wheel are 1: 9.
Described hand pushes away device for coal, and gear wheel is wherein fixedlyed connected by connecting key with Large Gear Shaft During.
A kind of hand of the present utility model pushes away device for coal, adopts the manual gear deceleration device as power source, is used for molded coal boiler and advances the coal operation, saved the electronic equipment cost of advancing device for coal, and simple in structure, easy to operate, labour intensity is less, is suitable for middle-size and small-size molded coal boiler and uses.

The specific embodiment
Below in conjunction with accompanying drawing hand of the present utility model being pushed away device for coal is described in detail.
Hand of the present utility model shown in Figure 1 pushes away device for coal a mechanical reduction gear 5, and a driving gear 7 is arranged in mechanical reduction gear 5, and with the gear wheel 10 of driving gear 7 engagements, the gear ratio of the two is 1: 9.Be fixed with Large Gear Shaft During 12 by connecting key 11 in the centre bore of gear wheel 10, the outer end of this Large Gear Shaft During joins by a connecting bushing 26 and profile modified gear axle 18, the other end of profile modified gear axle is fixed with profile modified gear 17, spur rack 19 and profile modified gear 17 engagements.An axis hole is arranged at supporting seat 16 tops, profile modified gear axle 18 passes this axis hole and connecting bushing 26 joins, the bottom of supporting seat 16 is fixed with a roller shaft 29, in the roller shaft outside roller axle sleeve 24 is arranged, this roller axle sleeve 24 is used for support spur rack 19, and the both sides of above-mentioned rollers axle sleeve are provided with rib, can guarantee spur rack 19 unlikely deflecting in the reciprocating motion process by this rib, front end at spur rack 19 is fixed with flange, is connected with moulded coal carriage on the boiler by this flange.The motive power that drives the action of said gear deceleration device is to provide by handle 1 and rocking arm 2, and an end of driving gear shaft 3 is fixed in the centre bore of driving gear 7, and the other end is fixedlyed connected with rocking arm 2.
Shown in Figure 2 is the spur rack structural representation, and there is a rack lengthening bar 20 spur rack 19 front portions among the figure, has a flange 21 to be used for being connected with the moulded coal supporting plate at the rack lengthening boom end.Plate washer 4 is a limiting plate.
During work, as long as shake handle 1, drive gear wheel 10 when driving gear 3 rotates and rotate, Large Gear Shaft During 12 is given profile modified gear axle 18 by connecting bushing 26 with transmission of power, and the profile modified gear axle orders about profile modified gear 17 and rotates and drive spur rack 19 and advance or retreat when rotating.When being set to handle 1 usually and clockwise rotating, spur rack advances, and promotes the coal of advancing before the moulded coal carriage.When handle 1 rotated counterclockwise, spur rack 19 retreated.
