Description

A kind of blow box

Technical field

The invention belongs to blast apparatus, be specially a kind of blow box.

Technical background

In some mountain area or build the road, repair open-air building sites such as bridge and need light a fire when cooking; Because power supply is unstable or do not have electric power at all, electric blower can't use, can only spontaneous firing or combustion-supporting with pectinids such as fans; This method is lit a fire and is smoldered easily; The faggot burning is insufficient, and the efficient of lighting a fire is not high, therefore is badly in need of a kind of small and exquisite, convenient, effective, manual fanning tool.

Summary of the invention

For addressing the above problem, the purpose of this invention is to provide a kind of blow box, this device can make things convenient for open-air blowing to use, and blowing efficient is high, to satisfy the needs of interim blowing.

The technical scheme that the present invention taked is: a kind of blow box; It is formed structure and comprises casing, upper cover plate, piston, pull bar, left air inlet and left valve plate thereof, right air inlet and right valve plate thereof and go out tuyere; It is characterized in that a box partition is divided into two parts up and down with casing, top is plunger shaft; Left side air inlet and left valve plate thereof are positioned at the right side that the left side of plunger shaft, right air inlet and right valve plate thereof are positioned at plunger shaft, are respectively equipped with left air outlet and right air outlet at the two ends of box partition; The bottom is flat air-out chamber; Going out tuyere is the level of state and is arranged on air-out chamber middle part; Air-out chamber dividing plate with the air-out chamber with go out that tuyere is divided into left air-out chamber and right air-out chamber, a left side goes out tuyere and the right side goes out tuyere; Described left air outlet and right air outlet are communicated with left air-out chamber and right air-out chamber respectively, go out the tuyere and the right side on a left side and go out tuyere and be respectively equipped with that a left side goes out the tuyere valve plate and the right side goes out the tuyere valve plate.

Be provided with the right block of piston left side block and piston respectively at plunger shaft inwall both ends.

Described upper cover plate and casing are pegged graft.

The invention has the beneficial effects as follows: because be provided with left air-out chamber and right air-out chamber, a left side goes out tuyere and the right side goes out tuyere, makes piston all can dry at any stroke, blowing efficient is high, this device can satisfy the needs of interim blowing, convenient open-air blowing.

Description of drawings

Fig. 1 is the present invention's center cross-sectional schematic longitudinally;

Fig. 2 is a vertical view of the present invention.

Among the figure: 1 casing, 2 pistons, 3 upper cover plates, 4 pull bars, 5 right air inlets; 6 right air outlets, 7 right valve plates, the right block of 8 pistons, 9 right air-out chambeies, 10 air-out chamber dividing plates; 11 right sides go out tuyere, and 12 left sides go out tuyere, 13 left air-out chambeies, 14 box partitions, 15 left air outlets; 16 left air inlets, 17 left valve plates, 18 pistons left side block, 121 left sides go out the tuyere valve plate, and 111 right sides go out the tuyere valve plate.

The specific embodiment

Like Fig. 1, a kind of blow box, it is formed structure and comprises casing 1, upper cover plate 3, piston 2, pull bar 4, left air inlet 16 and left valve plate 17 thereof, right air inlet 5 and right valve plate 7 thereof and go out tuyere that pull bar 4 is connected on the piston 2.The structure of left and right valve plate is the size platy structure suitable with its air inlet, and the valve plate upper end is hinged on box inside, plays a part to open or close air inlet.

One box partition 14 is divided into two parts up and down with casing 1, and top is plunger shaft, and piston is move left and right in this chamber.Two parts before and after this plunger shaft is divided into by piston, left side, right air inlet 5 and right valve plate 7 right sides thereof that left air inlet 16 and left valve plate 17 thereof are positioned at plunger shaft are positioned at the right side of plunger shaft, are respectively equipped with left air outlet 15 and right air outlet 6 at the two ends of box partition.Lower box is flat air-out chamber; Go out tuyere and be arranged on middle part, air-out chamber; The axis that goes out tuyere is provided with (promptly perpendicular to the vertical side of casing) in horizontal direction; Air-out chamber dividing plate 10 with the air-out chamber with go out tuyere and be divided into that left air-out chamber 13 goes out tuyere 12 with right air-out chamber 9, a left side and the right side goes out tuyere 11, the dividing plate mouth outer rim of following the wind in air-out chamber flushes.Described left air outlet 15 is communicated with left air-out chamber 13 and right air-out chamber 9 respectively with right air outlet 6, goes out tuyere 12 and the right side on a left side and goes out tuyere 11 and be respectively equipped with that a left side goes out the tuyere valve plate and the right side goes out the tuyere valve plate.It is rectangular with the port that the right side goes out tuyere 11 that a left side goes out tuyere 12; A left side goes out tuyere valve plate 121 and goes out tuyere valve plate 111 for being a bit larger tham the rectangular sheet of this side air-out mouth with the right side, and like Fig. 2, the rectangular sheet upper end is hinged on the port outside that goes out tuyere accordingly; Be the state of hanging, to realize to going out opening or closing of tuyere.

Be provided with piston left side block 18 and the right block 8 of piston respectively at plunger shaft inwall both ends, to prevent the piston slippage.

Described upper cover plate and casing are pegged graft, and can extract out from an end, are convenient to inspection and maintenance.

When needs were dried, pull bar 4 moved right, and piston 2 moves right, and closed under the effect of valve plate 7 at the right air inlet 5 of bellows under the pressure of wind, and wind goes out tuyere valve plate 111 through right air outlet 6, right air-out chamber 9, the right side to be opened, and wind goes out tuyere 11 and blows out from the right side.Meanwhile, the valve plate 17 of left air inlet 16 is opened, and a left side goes out tuyere valve plate 121 to be closed, and wind gets into the right part bellows.When pull bar 4 is moved to the left, just in time opposite with the above-mentioned course of work.Tubular tie does not still move right left like this, and wind all constantly blows out from tuyere.
