Abstract
The utility model relates to a sensing device for a plow lifting position of a tractor, which mainly comprises a lifting arm, an eccentric wheel plate, a lifting shaft, a connecting pin, a lifting shaft support on a tractor body, a sensor support on the tractor body, a sensor locking nut and a sensor. The lifting arm is sleeved on the lifting shaft through a spline and tightly props against the shoulder of the lifting shaft, the eccentric wheel plate is then sleeved on the lifting shaft, tightly props against the end face of the spline hole of the lifting arm and is connected with the lifting arm through the connecting pin, the lifting shaft with the lifting arm and the eccentric wheel plate is inserted in the hole of the lifting shaft support on the tractor body, the sensor is screwed in the hole of the sensor support on the tractor body, a steel ball at the sliding end of the sensor props against the eccentric wheel plate, and the sensor is locked by the sensor locking nut. The problem of universal use of the sensor for the plow lifting position of the tractor can be solved, and the device can be used on different suspension devices only through adjusting the relative positions of the centers of three circles of the eccentric wheel plate.
Description
Technical field
The utility model belongs to the tractor field, relates to a kind of sensing device, relates in particular to a kind of tractor plough raise-position and puts sensing device.
Background technology
At present, the two kinds of patterns that have that sensing device generally adopts are put in the plough raise-position of being disposed on the tractor of domestic production: a kind of is to be connected connecting rod on the lift shaft by a cover leverage mechanism, the rotational angle of lift shaft is become linear displacement signal, act directly on the control plough and rise on the control valve spool of device; Another kind is to weld an off-centre operation in lifter on the lift arm, and by a lobe plate, a cover leverage mechanism becomes linear displacement signal to the rotational angle of lift shaft, acts directly on the control plough and rises on the control spool of device.Above dual mode is all pure mechanical driving device, and structure is complicated, and control accuracy is relatively poor, is difficult to satisfy modern big-power tractor electronics plough and rises the needs of control.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, easy for installation, use reliable, take up room little, fault-tolerance is strong, can satisfy the tractor plough raise-position that hyundai electronics control requires and put sensing device.
The technical solution of the utility model is: sensing device is put in the tractor plough raise-position, mainly comprises: the lift shaft bearing on lift arm, eccentric wheel plate, lift shaft, connecting pin, the tractor body, the sensor support base on the tractor body, sensor locking nut, sensor; With lift arm by spline housing on lift shaft, and be close on the shoulder of lift shaft, again the eccentric wheel sleeve-board on lift shaft, and be close on lift arm splined hole end face, with connecting pin eccentric wheel plate is connected with lift arm, again in the lift shaft bearing hole on the lift shaft insertion tractor body that has lift arm, eccentric wheel plate, in the sensor support base hole of sensor spinning on tractor body, and the sliding end steel ball that makes sensor withstands on the eccentric wheel plate, with the sensor locking nut sensor locked.
The utility model can reach following beneficial effect: solved the generalization that sensing is put in the tractor plough raise-position, only needed to adjust the relative position of the eccentric wheel plate three round hearts, can use on different suspension arrangements.In the use, after the eccentric wheel plate wearing and tearing, can take off, still can keep sensing accuracy after the upset, continue to use.
Description of drawings
Fig. 1 puts the structural representation of sensing device for the raise-position of the utility model tractor plough.
Fig. 2 puts the fitting arrangement of sensing device on tractor for the raise-position of the utility model tractor plough.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.As shown in Figure 1, this type tractor plough raise-position is put sensing device and is mainly comprised: the lift shaft bearing 5 on lift arm 1, eccentric wheel plate 2, lift shaft 3, connecting pin 4, the tractor body, the sensor support base 6 on the tractor body, sensor locking nut 7, sensor 8; Lift arm 1 is connected on the lift shaft 3 by spline, and be close on the shoulder of lift shaft 3, eccentric wheel plate 2 is set on the lift shaft 3, and be close on lift arm 1 splined hole end face, with connecting pin 4 eccentric wheel plate 2 is connected with lift arm 1, again in lift shaft bearing 5 holes on the lift shaft 3 insertion tractor bodies that have lift arm 1, eccentric wheel plate 2, in sensor support base 6 holes of sensor 8 spinnings on tractor body, and the sliding end steel ball of sensor 8 is pushed up on the eccentric wheel plate 2.
When lift arm 1 is rotated counterclockwise extreme lower position, as shown in Figure 2, when oil cylinder piston bar 12 was fully retracted cylinder body 11, lift arm 1 reached extreme lower position; Continue again the sensor support base 6 interior pitch on the tractor body of being threaded on sensor 8 housings are locked sensor 8 with sensor locking nut 7, can normally use.
As shown in Figure 2, eccentric wheel plate 2 is made up of three circular cross sections, is respectively the face of cylinder that contacts with sensor 8, the cylindrical hole that eccentric wheel plate 2 links to each other with lift shaft 3, make the pin-and-hole that is connected of eccentric wheel plate 2 and lift arm 1 interlock, the three round hearts structurally draw a straight line.In addition, the eccentric wheel plate 2 that is enclosed within on the lift shaft 3 is the drivings of leaning on connecting pin 4, and eccentric wheel plate 2 can be rotated around lift shaft 3 with lift arm 1.
When lift arm 1 turns clockwise by lifting arm 9 drive suspension arrangement lower links 10, eccentric wheel plate 2 is also thereupon around lift shaft 3 rotations, the sliding end that promotes sensor 8 is to the right in the indentation sensor housing, sensor 8 just is converted into voltage signal to its sliding end (left end) with respect to the position variation signal of sensor 8 shell ends (right-hand member), thereby reaches the purpose of sensing hanger lower link 10 positions.
There are linear ratio relation one to one in the size of voltage signal and sensor 8 sliding ends (left end) with respect to the position of sensor 8 shell ends (right-hand member).
The utility model has solved the generalization that sensing is put in the tractor plough raise-position.In the use, after 2 wearing and tearing of eccentric wheel plate, take off upset after, still can keep sensing accuracy, and continue to use.
