Summary of the invention
The object of the invention is the deficiency in order to make up prior art, provide a kind of automatically controlled spacing in the rows knob to recruit the accurate seeding and fertilizer spreading machine of formula corn, the size of setting spacing in the rows has been come only by the automatically controlled knob of rotation, operate especially easy, eliminate the setting of driving gear, reduce pollution, save material, cost.Change the mode driving seeding unit work by land wheel in the past simultaneously, by drive motors at real-time response Running Speed of Tractor, under ensureing the prerequisite of selected spacing in the rows, directly export corresponding rotating speed and drive seeding unit work, avoid broadcast leakage, sow the phenomenons such as irregular.
The present invention is achieved through the following technical solutions:
A kind of automatically controlled spacing in the rows knob is recruited the accurate seeding and fertilizer spreading machine of formula corn, include mainframe, it is characterized in that: above described mainframe rear portion, fertilizer can is installed, fertilizer apparatus is provided with on the downside of described fertilizer can, described fertilizer apparatus front lower place is provided with plough, and plough is connected with fertilizer apparatus by defertilizing tube; Be provided with land axle below described mainframe front portion, described land axle two ends are provided with land wheel and are placed in mainframe both sides respectively; Be provided with seeding unit above described mainframe front portion, described seeding unit front lower place is also provided with plough, and described plough is connected with seeding unit by discharging tube; Drive motors, accumulator, controller and checkout gear are installed above in the middle part of described mainframe, described drive motors drives seeding unit work by Chain conveyer and gear drive, described checkout gear comprises wheel speed sensors and signal adapter, is contained on the wheel hub of tractor when described wheel speed sensors inductive head works.
Described land axle left end is separately equipped with drive sprocket, and described fertilizer apparatus is arranged on a line shaft, and described fertilizer apparatus line shaft left end is provided with drive sprocket, and is connected with land axle left end drive sprocket by chain.
The bottom of described seeding unit is provided with leakage charging tray, and the rotation of described leakage charging tray is driven by its bottom driven gear, and described driven gear is provided with travelling gear by its side and drives.
Described travelling gear is duplex chain wheel gear, and described duplex chain wheel gear is by drive motors by chain-driving, and described drive motors provides electric energy by accumulator.
Described drive motors, accumulator, to be interconnected by wire between controller and checkout gear, after described checkout gear detects that tractor travels wheel speed signal, change and transfer to controller, controller is by control program process, obtain relation function result and be converted to corresponding signal exporting, excite drive motors to respond, described controller is separately connected with gauge tap and is dragged to tractor cab.
Described controller inside is equipped with the control program controlling different spacing in the rows size and drive motors rotating speed, described gauge tap plate has the knob of adjusting planting distance size.
Its principle is: drafted a relation function, with the mid-control program having different spacing in the rows size corresponding of Time Controller between Running Speed of Tractor, drive motors output speed and corn plants distance.Rotary switch selectes a kind of spacing in the rows, and checkout gear is changed and transfers to controller after detecting that tractor travels wheel speed signal, and controller, by control program process, obtains relation function result and is converted to corresponding signal exporting, swash generator responds; Accumulator provides electric energy for motor, and the kinetic energy that motor exports drives seeding unit work by Chain conveyer, gear drive, realizes accurate seeding; In work, land wheel drives fertilizer apparatus work by Chain conveyer, due to not high to the status requirement of fertilising, so the skidding of land wheel does not affect fertilization effect.
Advantage of the present invention is:
Reasonable in design of the present invention, adopts the mode of driven by motor seeding unit work, avoids broadcast leakage and the irregular phenomenon of sowing; Spacing in the rows is regulated and controled in automatically controlled mode, simple and reliable, comparatively intelligent.
Embodiment
See accompanying drawing, a kind of automatically controlled spacing in the rows knob is recruited the accurate seeding and fertilizer spreading machine of formula corn, include mainframe 1, mainframe 1 is provided with fertilizer can 15 above rear portion, fertilizer apparatus 16 is provided with on the downside of fertilizer can 15, fertilizer apparatus 16 front lower place is provided with plough 18, and plough 18 is connected with fertilizer apparatus 16 by defertilizing tube 19; Mainframe 1 is provided with land axle 3 below front portion, and land axle 3 two ends are provided with land wheel 4 and are placed in mainframe 1 both sides respectively; Mainframe 1 is provided with seeding unit 2 above front portion, and seeding unit 2 front lower place is also provided with plough 5, and plough 5 is connected with seeding unit 2 by discharging tube 6; Drive motors 7, accumulator 8, controller 9 and checkout gear 10 are installed above in the middle part of mainframe 1, drive motors 7 drives seeding unit 2 to work by Chain conveyer 22 and gear drive 23, checkout gear 10 comprises wheel speed sensors 11 and signal adapter 12, is contained on the wheel hub of tractor when wheel speed sensors 11 inductive head 13 works; Land axle 3 left end is separately equipped with drive sprocket, and fertilizer apparatus 16 is arranged on a line shaft 17, and fertilizer apparatus 16 line shaft 17 left end is provided with drive sprocket 20, and is connected with land axle 3 left end drive sprocket by chain 21; The bottom of seeding unit 2 is provided with leakage charging tray, and the rotation of leaking charging tray is driven by its bottom driven gear, and driven gear is provided with travelling gear 23 by its side and drives; Travelling gear 23 is duplex chain wheel gear, and duplex chain wheel gear is by drive motors 7 by chain-driving, and drive motors 7 provides electric energy by accumulator 8; Drive motors 7, accumulator 8, to be interconnected by wire between controller 9 and checkout gear 10, after checkout gear 10 detects that tractor travels wheel speed signal, change and transfer to controller 9, controller 9 is by control program process, obtain relation function result and be converted to corresponding signal exporting, excite drive motors 7 to respond, controller 9 is separately connected with gauge tap plate 14 and is dragged to tractor cab; Controller 9 inside is equipped with and calculates the single-chip microcomputer that tractor travels relation between wheel speed and drive motors 7 response speed.
