The present invention is further described below in conjunction with embodiment and accompanying drawing thereof.
The grain header pneumatic separation device (see Fig. 1-3) of the present invention's design, is characterized in that described pneumatic separation device 3 comprises air amplifier section 31, gas pipeline 32 and air pump 33; Air amplifier section 31 comprises amplifier cover 311, amplifier support 312, air amplifier 313 and wind deflector 314; Gas pipeline 32 comprises air induction hose 321, hydraulic quick coupler 322 and air supply hose 323; Described air amplifier 313 and amplifier support 312 parallel arranged, be placed in amplifier cover 311, the two is installed on original blower fan place.Described amplifier cover 311 air inlet is network structure (see Fig. 2), to prevent foreign material from blocking air amplifier 313 negative pressure hole, reduces selection by winnowing effect; Sidewall has hole 3111, and hole 3111 inwall has sheet rubber 3112, to prevent the air induction hose 321 that weares and teares; Exhaust outlet in described amplifier cover 311 is provided with wind deflector 314, thus guides air-flow; In described amplifier cover 311, amplifier support 312 is installed, with fixed air amplifier 313.The air source hole of described air amplifier 313 is connected with air induction hose 321 one end, and malleation hole (i.e. the air outlet of air amplifier 313) is just to wind deflector 314; Described air induction hose 321 other end is connected with the one end fits of hydraulic quick coupler 322 through hole 3111, and the other end of hydraulic quick coupler 322 and the air supply hose 323 of gas pipeline 32 are connected, and air supply hose 323 and air pump 33 are connected.
Described air amplifier 313 is commercial products, it is the product utilizing Koln to reach air enlarge-effect-hydromechanical general principle to make, by inputting a small amount of compressed air as power, its one end produces underbalance effect, the compressed-air actuated initial air-flow of the other end converges around after mass air flow, produces high speed eluting gas.Grain header of the present invention is exactly utilize this air-flow to complete cleaning at random cereal.
Amplifier cover 311 of the present invention, air amplifier 313, position and the connected mode of air induction hose 321 and wind deflector 314 etc. are not limited to above-described embodiment, and the even whole adjustment in local does not affect the function of pneumatic separation device of the present invention.
Of the present inventionly to be further characterized in that (see Fig. 3): described amplifier support 312 is made up of the arc 3121 of two symmetrical structures, and the lower end of each arc 3121 is with two supporting legs 3123, and upper end is with mounting edge 3122; Mounting edge 3122 couples together, two arcs 3121 to lock by bolt.
The structure of described amplifier support 32 is not limited to this embodiment, and the change of local does not affect the structure of its function all within the protection domain of this invention.
The quantity basis designing requirement of amplifier cover 311 of the present invention, amplifier support 312, air amplifier 313, air induction hose 321 and wind deflector 314 etc. is selected.The amplifier section of embodiment is three; But its number is not limited to this embodiment.
Further technical scheme of the present invention is: design a kind of grain header, it is characterized in that pneumatic separation device of the present invention selected by this grain header, and its usage quantity is determined according to production engineering specifications.This grain header mainly comprises feeding part 1, shuttle board 2, pneumatic separation device 3, threshing cylinder 4, cleans part 5 and grain storage part 6(see Fig. 1 specifically).Wherein, shuttle board 2 is positioned at the below of feeding part 1, and threshing cylinder 4 is positioned at the rear of feeding part 1, clean the below that part 5 is positioned at threshing cylinder 4, grain storage part 6 is positioned at the below of cleaning part 5, and pneumatic separation device 3 is positioned at below shuttle board 2, one-level silo 64 front end of grain storage part; Described part 5 of cleaning comprises large magazins' layout sieve 51, sorting screen 52 and tail sheet 53; Grain storage part 6 comprises that one-level connects grain plate 61, secondary connects grain plate 62, one-level silo 64 and secondary silo 63.The pneumatic separation device quantity of embodiment is 3 covers.
