Description

An anti-rollover detection device for harvesting locomotive body balance

technical field

The invention relates to the technical field of grain harvesting machinery, in particular to an anti-rollover detection device for body balance of a harvesting locomotive.

Background technique

The working environment of harvesting machinery is complex, especially in the mountains and hills in the northwest, where the center of mass of grain harvesting machinery is high, and the center of mass of the vehicle body changes in real time due to changes in the terrain and under different working conditions during the work process, and The load-bearing difference between the front and rear axles is large, which leads to the overall deviation of the vehicle body and is prone to rollover. At present, there are few studies on the anti-rollover of the vehicle body. driving safety cannot be guaranteed.

Contents of the invention

In order to overcome the above-mentioned technical problems, the present invention provides an anti-rollover detection device for body balance of a harvesting locomotive.

The technical solution adopted by the present invention to solve the technical problem is: an anti-rollover detection device for harvesting locomotive body balance, including car body, support rod, probe fixing plate, double-sided fixing table, guide wheel, limit switch , slider, probe, lead screw, motor, front support plate, arc guide rail, spring, the car body is welded with the support rod, and the support rod and the front support plate are matched by welding; the probe fixed plate Cooperate with the slider through bolts, and the bilateral fixed platforms are symmetrically welded on both sides of the probe; the guide wheel and the slider cooperate with each other through shaft holes, and the limit switch is welded on the bilateral fixed platforms; The probe is matched with the spring through the shaft hole, and the spring is matched with the probe fixing plate through the shaft hole.

Further, the guide wheel cooperates with the arc guide rail, and when the screw rod drives the slider to move, the guide wheel slides on the arc guide rail; the lead screw and the slider cooperate through the shaft hole, and the motor output shaft and the wire The rods cooperate with each other. When the motor rotates, the lead screw drives the slider to move, thereby driving the probe to move laterally to detect the working environment in front of the harvester.

The beneficial effect of the present invention: the structure is simple, the slider and the lead screw cooperate with each other, when the motor rotates, the motor drives the lead screw to rotate, and at the same time the slider drives the probe to move left and right, the real-time working environment can be detected in real time, and when the probe moves laterally When there is an obstacle in front, the probe stops moving when it touches the limit switch, and the upper computer controls the vehicle body for leveling.

Detailed ways

With reference to accompanying drawing 1 to accompanying drawing 5 of the present invention, a kind of anti-rollover detecting device for harvesting locomotive body balance is described in detail below.

An anti-rollover detection device for harvesting locomotive body balance, including a car body 1, a support rod 2, a probe fixing plate 3, a double-sided fixing platform 4, a guide wheel 5, a limit switch 5, a slider 7, and a probe 8. Lead screw 9, motor 10, front support plate 11, arc guide rail 12, spring 13, the car body 1 is welded to the support rod 2, and the support rod 2 is welded to the front support plate 10; The probe fixing plate 3 and the slider 7 cooperate with each other through bolts, and the bilateral fixing table 4 is symmetrically welded on both sides of the probe; the guide wheel 5 and the slider 7 cooperate with each other through the shaft hole, and the limit The switch 6 is welded on the fixed platform 4 on both sides; the probe 8 cooperates with the spring 13 through the shaft hole, and the spring 13 cooperates with the probe fixing plate 3 through the shaft hole.

Further, the guide wheel 5 cooperates with the arc guide rail 12, and when the screw rod 9 drives the slider 7 to move, the guide wheel 5 slides on the arc guide rail 12; the lead screw 9 cooperates with the slider 7 through the shaft hole , the output shaft of the motor 10 cooperates with the lead screw 9, and when the motor 10 rotates, the lead screw 9 drives the slider 7 to move, thereby driving the probe 8 to move laterally to detect the working environment in front of the harvester.

When working, the motor 10 starts to rotate, and the lead screw 9 drives the slide block 7 to move left and right on the lead screw 9. At the same time, the probe 8 on the slide block 7 can detect the working environment in front of the harvester. When the probe 8 touches the When there is an obstacle, the stop of the probe 8 is controlled by the limit switch 6, and finally the device feeds back the collected information to the control system to realize the automatic leveling of the vehicle body.

The above descriptions are only specific implementation methods of the present invention, and any changes that can be easily conceived by those skilled in the art within the disclosed scope of the present invention shall be covered within the protection scope of the present invention.
