Embodiment
Further to illustrate the present invention to reach the technological means and effect that predetermined goal of the invention is taken, below in conjunction with
Accompanying drawing and preferred embodiment, to embodiment, structure, feature and its effect according to the present invention, describe in detail as follows：
A kind of Sowing machine for potatoes of efficiently seeding, as shown in figs. 1-7, including mainframe and is arranged on mainframe front end
Suspension arrangement, in the present embodiment, suspension arrangement is provided with three handgrips for being used to connect, and is connected to tractor or other agricultures
With on car.Also include being arranged on seed dropping mechanism in the middle part of mainframe, the land wheel running gear of mainframe bottom, master control system and
It is arranged on the rotary cultivator attachment of mainframe front bottom end.
Seed dropping mechanism includes being used for the power transmission shaft company of the motor that power is provided separately, motor and upper driving wheel
Connect, upper driving wheel and lower driving wheel drive at least one spoonful of chain, and the quantity of increase spoon chain can improve sowing efficiency, but excessive
Increase spoon chain quantity, the volume of whole seeder will be caused to increase.In the present embodiment, the quantity of spoon chain is two.
Equally spaced setting is several on spoon chain takes kind of a spoon, takes kind of spoon to be provided with tinsel,
Accordingly, Hall sensor is fixedly installed in the side of spoon chain, is ceaselessly revolved in the presence of chain when taking kind of spoon
When turning, Hall sensor can detect the tinsel taken on kind of spoon, then by the information transmission received to master control system
Operating control device, then control two correlation photoelectric sensors to work, when take have potato kind in kind of spoon when, then controlling spoon chain just
Often operating, does not have potato kind when taking in kind of spoon, then when taking turns to this and taking the potato kind in kind of spoon to sow, then spoon chain accelerated service.From above-mentioned
Operation process in it can be found that correlation photoelectric sensor is located at the top of Hall sensor.Outside the descent path for taking kind of spoon
Side is provided with catch, prevents potato kind offset track, and sowing just or is not fallen on outside seeder, takes the ascending path of kind of spoon to pass through plants case
To take kind.Preferably, the material of catch is transparent plastic, can observe the transmission situation in it.
Vibrating motor is provided between upper driving wheel and lower driving wheel, vibrating motor is arranged on mainframe, eccentric wheel and
Vibrating motor is connected by fixed cover, and when vibrating motor work rotates, band movable eccentric wheel rotates, and side and the spoon of eccentric wheel link
Touch, due to the effect of eccentric wheel, spoon chain will by a loosening and a tightening, when taking kind of a spoon to move at eccentric wheel, it will vibration is produced, this
When, if take the potato kind for having two or more in kind of spoon, it can be fallen down during vibration, leave one, keep away
Exempt from two kinds of a hole or block feed mechanism for seed.
Due to the effect of vibrating motor, spoon chain will force upper driving wheel ceaselessly low amplitude vibrations, therefore in the wheel of upper driving wheel
Damping spring is set on axle, and the damping spring is connected with mainframe.First, the damping spring can reduce the wheel shaft of upper driving wheel
The friction of continuous shearing force, second, in the case where not influenceing sowing, alleviates the vibration frequency of whole seed dropping mechanism.
Land wheel running gear includes land wheel, land wheel shaft gear and land axle, and speed sensor, the speed are provided with land wheel
Inductor is electrically connected with operating control device, and the action speed for measuring land wheel is delivered to master control system by speed sensor, so
The rotary speed of spoon chain is controlled afterwards, makes sowing uniform.
Master control system includes operating control device and display screen, is easy to that working order can be paid close attention in real time on a display screen.
Rotary cultivator attachment includes rotary cultivator protector, rotary blade main shaft and rotary blade, and rotary cultivator protector is arranged on rotation
The front end of knife is ploughed, plays a part of protection.Rotary blade is arranged on rotary blade main shaft, and rotary blade includes several arc cutter groups
Into the thickness of arc cutter from installation portion (at rotary blade main shaft) to cutting part (knife-edge part) is gradually reduced, and arc cutter is cut
Cut portion and carry out wedge angle processing provided with the multiple tracks groove along blade direction, the side of groove, so, even if running into rubble or hard
Soil block, part rubble can also reduce by groove and remove the edge of a knife, avoid wearing cutter.
Complete machine operation principle：Whole seeder hangs on rear tractor suspension arrangement in a manner of trifilar suspension,
Power drives rotary blade to carry out tillage operation by tractor motive power output shaft by universal joint drive rotary blade main shaft, positioned at rotary tillage
Rotary cultivator protector in front of machine is protected rotary tillage process, while carrying out rotary tillage, the fertilizer above rotary cultivator
Case carries out fertilizer operation, and machine advance plough carries out ditching operation, and speed sensor is pointed to turning for walking ground wheel shaft gear
Speed is detected, and conveys signal to operating control device, and controller is by controlling DC motor speed to arrange seed dropping mechanism
Kind speed matches with land wheel pace, obtains certain spacing in the rows, and direct current generator drives spoon chain to rotate, takes kind of a spoon to be taken from plants case
Kind, take kind of spoon to pass through and broadcast leakage detection is carried out to correlation photoelectric sensor, Hall sensor is entered by the detection to tinsel
Row counts, as spoon chain is run, when reach lack kind take kind of spoon when sensor send signal to controller, controller is to lacking kind of a direct current
Motor sends signal for faster, crosses scarce kind and takes kind of a spoon to be sowed, the spring below sprocket wheel subtracts to seed dropping mechanism
Shake.Ridging disk positioned at seed dropping mechanism rear carries out ridging, and the clean-up scraper positioned at ridging disk rear is by the soil after ridging
Ground strikes off, and the clear rut shovel at rear carries out the operation removing rut that breaks ground, and the overlay film positioned at the connection of mainframe rear suppresses bourdon tube
Film coating operation is carried out with overlay film spring, the press mold wheel crank being connected with mainframe and the pressing wheel that is connected with press mold wheel crank are to thin
Film is suppressed, and burette bracket, the drip irrigation plastic disc being connected with frame aft carry out drip irrigation zone laying, positioned at complete machine rear portion
Mamoty is helped to carry out helping native operation, the operating control device, display screen positioned at plants case side regulate and control to spacing in the rows, line-spacing.
Above with reference to preferred embodiment, invention has been described, but protection scope of the present invention is not restricted to
This, without departing from the scope of the invention, various improvement can be carried out to it and can be replaced wherein with equivalent
Part, as long as structural hazard is not present, the every technical characteristic being previously mentioned in each embodiment can combine in any way
Get up, and any reference in claim should not be considered as to the involved claim of limitation, no matter come from which point
See, embodiment all should be regarded as exemplary, and be nonrestrictive.Therefore, it is any to fall within the scope of the appended claims
