Description
Technical field
The utility model relates to a kind of sower, specifically is a kind of suction kind head of precision sower of tiny seed grain.
Background technology
Advantages such as seeding machinery is one of tool of production the most basic in the modernized agricultural production, and it has, and labour intensity is low, high efficiency, sowing are accurate are effectively avoided the seed waste, reduce production costs; Existing market mainly contains bigger paddy sower of seed grain and the less vegetable-seed planter of seed grain according to playing the seed difference, wherein vegetable-seed planter is because the very little and big or small inequality of seed grain, suction kind of head runs into particle when suction is planted minimum, and present suction kind head all can't directly be used for sowing the superfine seeds of particle such as tobacco, often need tobacco seed sugar-coat parcel during the sowing tobacco seed to increase seed, inhaling kind of a head when running into the sugar-coat breakage can directly be drawn into impurity and seed in the air intake passage of machine intimate, easily cause the fault of an inhomogeneous and whole sower of sowing, influence operating efficiency.
The utility model content
At the problems referred to above, the utility model provides a kind of suction kind head of precision sower, and its uneven and design at tiny seed grain specially has simple in structure, reliability and the good characteristics of precision.
For achieving the above object, the utility model is by the following technical solutions:
A kind of suction kind head of precision sower, it is characterized in that: comprise and inhale kind of a body, inhale kind of mouth and movable push rod, the front end of inhaling kind of a body offers axial movable chamber backward, the rear end of inhaling kind of a body offers gas hole forward, gas hole is communicated with movable chamber, movable push rod is contained in the movable chamber, inhale kind of mouth be screwed in inhale kind of a body front end with the movable top rod seal in movable chamber, the rear end of described movable push rod is provided with piston head, the sidewall in movable chamber is provided with suction hole, piston head cooperates with movable chamber isolates suction hole and gas hole, the front end of described movable push rod is provided with a thimble, thimble extends forward to stretch to inhales the suction hole of planting mouth, and the bore of thimble is less than the bore of inhaling suction hole on kind of the mouth.
Described movable push rod comprises motion bar and convergent-divergent piece, is provided with the thimble chamber at the front end of described motion bar, and the convergent-divergent piece is provided with in the thimble chamber, is provided with axial thimble through hole on the convergent-divergent piece, and described thimble passes the thimble through hole from the thimble chamber and extends to suction hole.
The utility model adopts the sowing structure of separating with inspiratory phase of blowing also will blow by movable push rod and the inspiratory phase isolation, and the thimble of cooperation activity push rod front end guarantees all even reliability of machine sowing by the operation principle of cylinder.
