Description
Technical field:
The utility model relates to a kind of notch board governor motion that is used for combine.
Background technology:
Combine notch board governor motion on the market is manual adjustments now.Manual adjustments needs parts such as placement of mechanical control crank, handle set in driver's cabin, takies quite a few already very crowded space; And only with naked-eye observation notch board and cylinder gap, naked-eye observation and actual error difference are excessive and handle more loaded down with trivial details in manipulation.
Summary of the invention:
The purpose of this utility model is to overcome the problem that above-mentioned manual adjustments exists, and provides a kind of by microcomputer monitored adjusting notch board and cylinder gap, accurately provide the automatically controlled concave clearance adjuster of True Data.
The technical solution of the utility model is, automatically controlled concave clearance adjuster, it is characterized in that, be movably hinged with a pair of lift arm at the two ends of preceding fixed mount seam, the other end of lift arm is hinged on the end of grain header notch board, be provided with positive silk holder at the middle part of a pair of lift arm concentric, anti-silk holder, the adjusting rod of band trapezoidal thread by and with positive silk holder, anti-silk holder matches, adjusting rod is connected the output of motor by shaft coupling, the shaft coupling of motor is equipped with magnet steel near on the motor side, be fixed with the sensing head that links to each other with micro computer on the motor casing, electric-controlled box is electrically connected with motor.
Further scheme is that the other end of lift arm is hinged on the end of grain header notch board by cage bolt, holder nut.
This mechanism adopts the contactless sensing principle of Hall, and the motor revolution moves a week, and the sensing head change in electric once feeds back to micro computer with the motor revolution, and micro computer can calculate the concave clearance.Simultaneously, the driven by motor adjusting rod rotates, and the rotation of adjusting rod causes that lift arm drives notch board one end and moves up and down, thereby regulates the concave clearance.
The beneficial effects of the utility model are: by microcomputer monitored adjusting notch board and cylinder gap, accurately provide True Data, computer is regulated control, effectively reduces percentage of damage, improves the degree that purifies.Adopt the employing of micro computer and the contactless sensing technology of Hall, make adjusting more convenient, data are accurate.Adopt the trapezoidal thread transmission to make axial stable drive, intensity is higher; In order to eliminate the side force that notch board and drive disk assembly bring because of the processing and fabricating error, in conjunction with the negative effect that can effectively avoid side force to bring, the gap was inconsistent before and after trace was regulated notch board simultaneously with holder nut, cage bolt simultaneously.
Description of drawings:
Fig. 1 is the utility model structure left surface schematic diagram.
Fig. 2 is that the A of the utility model structure is to rotation partial structurtes schematic diagram.
Among the figure: 1 electric-controlled box, closure plate before 2 micro computers, 3 grain headers, 4 fixed mount seam, 5 lift arms, 6 stop collars, 7 trip bolts, 8 clamp nuts, 9 positive holders, the movable notch board of 10 grain headers, 11 adjusting rods, 12 anti-holders, 17 motors, 18 harvester threshing cylinders, 19 cage bolts, 20 holder nuts.
T is the concave clearance
α is longitudinal axis stream grain header and body longitudinal angle
Distance between lift arm when L is the concave clearance maximum
Embodiment
As Fig. 1, Fig. 2.
Automatically controlled concave clearance adjuster, preceding fixed mount seam 4 one ends be the preceding closure plate 3 of grain header fixedly, and the other end is the grain header rear blocking plate fixedly, and the outer end of grain header rear blocking plate is provided with stop collar, and this stop collar is spacing by trip bolt 7, clamp nut 8.α is longitudinal axis stream grain header and body longitudinal angle.In preceding fixed mount seam, be movably hinged with a pair of lift arm 5 between the forward and backward closure plate of grain header, the other end of lift arm is hinged on the end of grain header notch board 10 by cage bolt 19, holder nut 20, with holder nut, cage bolt in conjunction with the negative effect that can effectively avoid side force to bring, the gap was inconsistent before and after trace was regulated notch board simultaneously, as Fig. 2.The coaxial heart in the middle part of lift arm is provided with positive silk holder 9, anti-silk holder 12, and the adjusting rod 11 of band rectangular thread is by positive silk holder, anti-silk holder and match, and adopts the trapezoidal thread transmission to make axial stable drive, and intensity is higher.Adjusting rod 11 is connected the output of motor 17 by shaft coupling, the shaft coupling of motor 17 is equipped with magnet steel near on the motor side, be fixed with the sensing head that links to each other with micro computer 2 on the motor casing, the motor revolution moves a week, the sensing head change in electric once, the motor revolution is fed back to micro computer, and micro computer can calculate the concave clearance.Electric-controlled box 1 is electrically connected with motor, handles electric-controlled box and can make the slowspeed machine forward or reverse.
Crop according to different periods, different location is required, makes the slowspeed machine forward or reverse by handling electric-controlled box.The adjusting rod that the motor upper coupling has trapezoidal thread rotates, the rotation of adjusting rod makes the positive silk holder 9 on adjusting rod, anti-silk holder 12 that axial displacement take place, lift arm drives notch board one end and moves up and down, thereby regulate the concave clearance T between notch board and the harvester threshing cylinder 18, distance between lift arm when L is the concave clearance maximum.
The electric control gear of entire mechanism is made up of micro computer, electric-controlled box, slowspeed machine and relevant wire harness.Electric-controlled box have " on ", D score, " stopping " third gear.Press " on " when shelves, the motor counter-rotating, it is big that concave clearance T becomes; When pressing " stopping " shelves, notch board is parked in chosen position; When pressing the D score shelves, concave clearance T diminishes.
Functional relation in the automatically controlled adjusting notch board governor motion between motor speed and the concave clearance is:
(N*P)
2＝140
2-(T+100)
2
N is motor revolution (unit: change)
P is a lead (unit: mm) P=3mm in this mechanism
T is a concave clearance (unit: mm) 5mm≤T in this mechanism≤40mm
