Description
Technical field
The present invention relates to the seeding apparatus in the farm machinery, particularly a kind of Pneumatic membrane installing precision punching planter.
Background technology
In agricultural seeder equipment, the use of air inhaling type fine sowing device is very universal, and its major advantage is to realize accurate sowing, i.e. Bo Zhong controllable number system so just can reduce the usage amount of seed greatly.At present, the air inhaling type fine sowing device mainly is made up of rack-mounted negative pressure seeder, kind case and cylinder, and the press mold circle is installed on cylinder, and the duckbilled dibbler is distributed on the circumference of cylinder, with each duckbilled dibbler corresponding section, all install by the inoculation box.As disclosed utility model patent in China Intellectual Property Office's on May 10th, 2006 " driven sucking precise amount planting after plastic covered device ", Granted publication number is CN2777935Y, and this technical scheme mainly is made up of rolling wheel type duckbilled bunch planting shell, seed chamber, negative pressure seeder.The subject matter that this device exists is: 1, complex structure.Owing on cylinder, be evenly equipped with a plurality of duckbilleds, between two duckbilleds in cylinder the inoculation box is installed, so just make this device duckbilled and to inoculate the quantity of box more, complex structure has increased the cost of processing and manufacturing; 2, speed of drilling is slow.Owing on the circumference of cylinder, be evenly equipped with a plurality of duckbilleds, when when sowing during excessive velocities, the rotary speed of cylinder is very fast, the seed that enters in inoculation box or the duckbilled can be under action of centrifugal force, attached to falling in the ground in inoculation box or the duckbilled, cause sky to broadcast the generation of phenomenon, simultaneously cylinder rotary speed when very fast, duck tongue on the duckbilled will be transferred to the seed of broadcasting in the soil when resetting, and also can cause sky to broadcast phenomenon; 3, the adjustment of seed spacing is difficult.Owing to uniform on the circumference of cylinder a plurality of duckbilleds are installed, when needs are adjusted seed spacing, can only be by changing the seed absorbing plate in the negative pressure seeder and changing duckbilled quantity on the cylinder and the quantity of inoculation box realizes.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, provide a kind of speed of drilling Pneumatic membrane installing precision punching planter fast, simple in structure.
The solution of the present invention is as follows: a kind of Pneumatic membrane installing precision punching planter, comprise frame, rack-mounted negative pressure seeder and press mold circle, the seed inlet of negative pressure seeder links to each other with the sowing port of kind of case, the sowing port of negative pressure seeder links to each other with discharging tube, discharging tube to go out kind of mouth corresponding with the seed inlet of duckbilled dibbler, it is characterized in that being installed with flange on the side of press mold circle, on the pivot of flange and press mold circle, be installed with driving shaft, one end of driving shaft is connected with frame is rotatable, the other end is fixed with pinion, be fixedly mounted on the power transmission shaft of negative pressure seeder with the gear wheel of pinion, on the flange face relative cam mechanism is installed with the negative pressure seeder, the duckbilled dibbler is fixed on the slide block, in the slide block chute that is installed on the slider frame moving up and down, slider frame links to each other with the negative pressure seeder, on the slide block position corresponding with cam mechanism finger or leverage is installed, and on the duckbilled dibbler back-moving spring is installed.
Above-mentioned driving-chain is formed by the pinion that is fixed on the driving shaft other end with the gear wheel of pinion, and gear wheel is fixedly mounted on the power transmission shaft of negative pressure seeder.
Above-mentioned cam mechanism be uniform be fixed on the concentric circle of flange pivot on oblique shape shifting block or arc shifting block or waveform shifting block form.
Above-mentioned cam mechanism be uniform be fixed on the concentric circle of flange pivot on little axle form.
Above-mentioned duckbilled dibbler is made up of with the duck tongue that links to each other with duckbilled stationary pipes, the duckbilled that is hinged on the stationary pipes lower end, stationary pipes and slide block are fixedly linked, the middle part of tabular duck tongue fixes on the duckbilled by hinges fixing, one side of duck tongue upper end contacts with the projection on being fixed on slider frame, another survey is equipped with stage clip, on the slide block position corresponding with cam mechanism finger is installed.
Above-mentioned duckbilled dibbler is made up of with the duck tongue that links to each other with duckbilled stationary pipes, the duckbilled that is hinged on the stationary pipes lower end, stationary pipes and slide block are fixedly linked, the middle part of tabular duck tongue fixes on the duckbilled by hinges fixing, one side of duck tongue upper end contacts with the projection on being fixed on slider frame, another survey is equipped with stage clip, on the slide block position corresponding with cam mechanism leverage is installed.
Above-mentioned leverage comprises that the middle part fixes on lever on the slider frame by hinges fixing, is equipped with finger with corresponding position, lever lower end on slide block.
On above-mentioned lever, return spring is installed.
Characteristics of the present invention: 1, simple in structure.Because this device has only a duckbilled, and will inoculate box and omit, and so just make this device compared with prior art, it is simple in structure, can significantly reduce manufacturing cost; 2, changed the motion mode of duckbilled.Existing rotatablely moving of duckbilled become moving up and down perpendicular to ground, be easy to overlay film is on the ground broken so on the one hand, seed is broadcast in the ground, on the other hand because the movement locus of duckbilled is a rectilinear motion, consistent with the movement locus of the seed of free-falling in the negative pressure seeder, the seed that falls can be very easy to and fall in the duckbilled dibbler accurately, so just can the generation that sky is broadcast phenomenon can not occur when improving speed of drilling; 3, the adjustment of seed spacing is easy.When needs are adjusted seed spacing, only needing to increase or reduce the cam mechanism quantity that is fixed on the flange just can realize, shortened adjustment time and difficulty on the one hand, Bo Zhong spacing can in very large range realize the adjustment of any distance as required on the other hand.
