The automatic tilling depth regulation and control system is characterized in that an output shaft of a motor is connected to the tilling depth regulation handle, the position of the tilling depth regulation handle is adjusted through variation of the length of the output shaft, a rotation angle measuring device is arranged on the tilling depth regulation rotating arm, the rotation angle measuring device and the motor are connected with a controller, and the controller regulates the length of the output shaft of the motor through the value fed back by the rotation angle measuring device to adjust the position of the tilling depth regulation handle and the depth of the plough. The tilling depth regulation handle is adjusted in time by monitoring the depth of the plough real timely, so that the depth conforms to a standard, and the problem of unstable and uneven tilling depth in actual work is solved.
Description
Technical field
The utility model relates to a kind of tilling depth controlled system with self-regulation.
Background technology
At present, domestic existing tractor is pulled the tilling depth regulating handle through manual work and is regulated tilling depth adjusting pivoted arm and then change the degree of depth that adopts plough the control manually control mostly of the ploughing degree of depth.So but manual adjustments tend to causes the instability of tilling depth and inhomogeneous.When tractor wear plough soft, wetland or soil specific resistance bigger on the plot during farming because tilling depth is bigger with change in resistance, the load of engine is with instability, tilling depth is understood inhomogeneous, cultivating quality does not reach agriculture requirement.When the arable land person also just probably regulates by rule of thumb, can accurately not be adjusted to the standard tilling depth when regulating tilling depth.Crossing when tilling depth influences the crops harvest when shallow, and tilling depth is crossed also can influence the crops harvest when dark, and can increase the tractor oil consumption, strengthens the tractor wearing and tearing, reduces the tractor life-span.
The utility model content
The purpose of the utility model is to provide a kind of tilling depth controlled system with self-regulation that can regulate tilling depth automatically.
To achieve these goals, adopt following technical scheme: a kind of tilling depth controlled system with self-regulation comprises tilling depth regulating handle and tilling depth adjusting pivoted arm; Tilling depth is regulated pivoted arm and is connected plough, and the rotation of tilling depth regulating handle drives the rotation that tilling depth is regulated pivoted arm; And then the degree of depth of regulating plough; It is characterized in that: be connected with motor output shaft on the tilling depth regulating handle, the position of the variation adjustment tilling depth regulating handle through output shaft length, tilling depth is regulated pivoted arm and is provided with rotating angle measurement apparatus; Rotating angle measurement apparatus all links to each other with controller with motor; The output shaft length that controller is regulated motor through the value of rotating angle measurement apparatus feedback adjusts the position of tilling depth regulating handle, thus the degree of depth of adjustment plough.
Said rotating angle measurement apparatus is to be separately positioned on tilling depth to regulate on the pivoted arm and the obliquity sensor on the plane, rotating shaft place on the pivoted arm.
Said tilling depth is regulated on pivoted arm and the pivoted arm and is connected with two sections hinged linkages on the plane, rotating shaft place, and said angle measurement unit is the potentiometer that is arranged in the linkage rotating shaft.
The utility model is in time adjusted the tilling depth regulating handle through the real-time degree of depth of monitoring plough, has guaranteed that the degree of depth meets standard, has better solved in the actual work problems such as tilling depth is unstable, inhomogeneous.
Description of drawings
Fig. 1 is used to the tractor structure sketch map of ploughing in the prior art;
Fig. 2 is the sketch map of tilling depth regulating handle part in the utility model;
Fig. 3 is the sketch map that tilling depth is regulated the pivoted arm part among the embodiment 1;
Fig. 4 is the sketch map that tilling depth is regulated the pivoted arm part among the embodiment 2.
Among the figure, 1 is tractor, and 2 is the tilling depth regulating handle, and 3 are tilling depth adjusting pivoted arm, and 4 are plough, and 5 is fixed hinge, and 6 is stepper motor, and 7 is threaded screw rod, and 8 is obliquity sensor, and 9 is bearing, and 10 is linkage, and 11 is potentiometer, and 12 are rotating shaft.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As shown in Figure 1; On scheming, can see several parts relevant with the utility model on the tractor 1: tilling depth regulating handle 2, tilling depth are regulated pivoted arm 3 and are ploughed 4; In the process of arable land, can drive the motion that tilling depth is regulated pivoted arm, and then change the degree of depth of plough in soil through pulling the tilling depth regulating handle.Wherein the interaction relation between tilling depth regulating handle and the tilling depth adjusting pivoted arm is a technique known, is not describing at this.
Embodiment 1, and as shown in Figures 2 and 3, the fixing pole in stepper motor 6 bottoms is supported, and pole is installed on the tractor 1 through fixed hinge 5.Stepper motor 6 rotating shafts connect a threaded screw rod 7, and the nut on threaded screw rod end and the tilling depth regulating handle 2 links together.Thereby the positive and negative rotation that drives threaded screw rod 7 during stepper motor 6 work drives tilling depth regulating handle 2 and rotates up and down, reaches the purpose of regulating tilling depth.Because the bottom of stepper motor 6 is installed on the tractor 1 through fixed hinge 5, so it can rotate around fixed hinge 5 along with the rotation of regulating handle 2.
On the dark pivoted arm obliquity sensor is installed respectively with regulating ploughing on the tractor;, tractor can record the difference of the detected value of two sensors when driving ploughing soil; Can calculate tilling depth according to difference and regulate the angle that pivoted arm changes with respect to tractor, thereby learn tilling depth.Controller rotates and reverse according to the FEEDBACK CONTROL stepper motor of tilling depth, thus the degree of depth of control plough automatically.
Embodiment 2, and like Fig. 3 and shown in Figure 4, different with embodiment 1 is the tilling depth detection mode.Tilling depth is regulated on pivoted arm and the pivoted arm and directly is connected with two sections hinged linkages on the plane, rotating shaft place, and the other end of linkage is fixed through rotating shaft, and rotating shaft is provided with potentiometer.Be fixed on potentiometer 11 usefulness supports on the tractor 1 when potentiometer 11 is installed, the rotating shaft 12 of potentiometer 11 links to each other through bearing 9 with the pivoted arm 3 of regulating tilling depth through a bar linkage structure 10.When pivoted arm 3 rotates when regulating tilling depth, the rotating shaft 12 of potentiometer 11 is followed tilling depth to regulate pivoted arm through the effect of linkage 10 and is rotated synchronously, detects the angle that tilling depth is regulated pivoted arm according to the variation of the resistance of potentiometer 11, thereby detects tilling depth.
