Abstract
The utility model relates to a negative attracting device for motor exhaust pipe apparatus, in particular to an air suction device which is suitable for being used on an air suction type seeding apparatus. The utility model comprises an air exhaust pipe, a throat pipe which is thinner than the air exhaust pipe is arranged on the exhaust pipe near the exit position, a negative pressure air suction branch pipe is arranged on the air exhaust pipe at the exit position of the throat pipe, an included angle smaller than 60 DEG is formed between the air suction branch pipe and the throat pipe, and a check valve is arranged on the branch pipe. The utility model has the advantages of simple structure and can accomplish the air suction work of the air suction type seeding apparatus without other motive power and exhaust fan, and the utility model has large air suction amount, continuous and stable air suction.
Description
The utility model relates to a kind of exhaust pipe of engine negative pressure soaking gas equipment, especially is suitable for the soaking gas equipment on the air-suction seeding unit.
Air-suction seeding unit such as the disclosed air-suction seeding unit of CN2056556U adopt flexible leather cup air-breathing at present, and this method inspiratory capacity is little can not be lasting, thereby can not guarantee seeding quality; Another kind is that air exhauster is installed, and this mode complex structure needs to increase air-blast device.
The purpose of this utility model provides and a kind ofly can guarantee the aspiration amount, and need not to add in addition the exhaust pipe of engine negative pressure soaking gas equipment of air-blast device.
The utility model comprises blast pipe, be characterized in that blast pipe near the exit, is provided with the trunnion that is narrower than blast pipe, the negative inspiratory pressure arm is arranged on the blast pipe in the exit of this trunnion, become one between this air-breathing arm and the trunnion less than 60 ° angle, bronchi is provided with one-way cock.
The utility model is simple in structure, needn't add power and air exhauster in addition, just can realize the aspiration work of air-suction seeding unit, and the aspiration amount is big, and is continual and steady.
Below in conjunction with accompanying drawing the utility model is further specified.Accompanying drawing is the utility model structural representation.The utility model comprises blast pipe (3), be provided with the trunnion (4) that is narrower than blast pipe at blast pipe near the exit, negative inspiratory pressure arm (2) is arranged on the blast pipe in trunnion exit, and this air-breathing arm is provided with one-way cock (1), and becomes the angle less than 60 ° between air-breathing arm and the trunnion.Its course of work is as follows, when the engine exhaust air communication is crossed trunnion (4), suddenly quicken, when going out trunnion, outside outlet, formed a negative pressuren zone, with the gas sucking-off in the air-breathing arm (2), because the effect of one-way cock (1), make in the air-breathing arm and can remain negative pressure state, finish aspiration seeding unit.
