The harvester 1 is provided with a height sensing device 2 for sensing the height change of the ridge surface 3, the height sensing device 2 comprises a height angle conversion mechanism and an angle measurer 9, the height angle conversion mechanism converts the height change condition of the ridge surface 3 into angle change, the angle change condition is measured through the angle measurer 9, and then the height change of the ridge surface 3 is reflected.
The height angle conversion mechanism comprises an upper fixed arm 5, a first movable arm 6, a lower measuring arm 7 and a second movable arm 8 which are sequentially hinged and connected into a parallelogram, wherein the upper fixed arm 5 is opposite to the lower measuring arm 7, and the first movable arm 6 is opposite to the second movable arm 8. The upper fixing arm 5 is fixedly arranged on the harvester 1, the lower measuring arm 7 is connected with a ridge pasting component 18, and the ridge pasting component 18 is attached to the ridge surface 3. The angle measurer 9 correspondingly measures the angle change of the first movable arm 6 or the second movable arm 8.
When the height of the ridge surface 3 changes, the ridge pasting component 18 changes along with the height change of the ridge surface 3, the height change of the ridge pasting component 18 enables the height of the lower measuring arm 7 to also change, and as the upper fixed arm 5, the first movable arm 6, the lower measuring arm 7 and the second movable arm 8 form a parallelogram, the height change of the lower measuring arm 7 can drive the first movable arm 6 and the second movable arm 8 to swing, so that the measured value of the angle measurer 9 is changed, the height change condition of the ridge surface 3 is fed back, and the height sensing of the ridge surface 3 is realized.
As shown in fig. 2, the lower measuring arm 7 is connected with a rotating shaft 10, and a downward end of the lower measuring arm 7 integrally extends out of the rotating shaft 10. The ridge pasting component 18 comprises a lever frame 11, the lever frame 11 is in an inverted U shape, the center of the lever frame 11 is rotatably arranged on the rotating shaft 10, two ends of the lever frame 11 are symmetrical, and two ends of the lever frame 11 are bent towards the ridge surface 3 and are pasted on the ridge surface 3 under the action of gravity. As shown in fig. 4, when one end of the lever frame 11 encounters an obstacle 4 such as a soil block or a stone, the end of the lever frame 11 is tilted, but since only one end of the lever frame 11 is tilted, the elevation of the lower measuring arm 7 may be smaller than the tilt of the end of the lever frame 11, thereby reducing the influence of the obstacle 4 on the height sensing device 2, and the angle change of the angle measurer 9 may be reduced when the obstacle 4 is encountered.
The two ends of the lever frame 11 are respectively provided with a ridge pasting plate 12, and the ridge pasting plates 12 slide along the ridge surface 3 when the harvester 1 moves along the ridges.

The ridge pasting plate 12 is arranged in a bending mode towards one end of the travelling direction of the harvester 1, so that when the ridge pasting plate 12 encounters an obstacle 4, the ridge pasting plate 12 can climb onto the obstacle 4, and the obstacle crossing effect is better. In order to make the ridge adhering plate 12 symmetrical from front to back, one end of the ridge adhering plate 12 facing away from the travelling direction of the harvester 1 is also arranged to be bent upwards.
The upper fixed arm 5 is hinged with a shape limiting sheet 13, a limiting groove 14 is formed in the shape limiting sheet 13, a limiting block 15 is arranged on the lower measuring arm 7, and the limiting block 15 is limited in the limiting groove 14 to limit the distance between the upper fixed arm 5 and the lower measuring arm 7 and further limit the swinging range of the first movable arm 6 and the second movable arm 8. As shown in fig. 2, one end of the shape limiting sheet 13 is hinged at the joint of the upper fixed arm 5 and the second movable arm 8, an elongated limiting groove 14 is formed in the shape limiting sheet 13, and the limiting block 15 correspondingly slides along the limiting groove 14 to limit the falling limit of the lower measuring arm 7. When the harvester 1 does not perform harvesting operation on the ridge surface 3, but only simply runs, the ridge pasting component 18 can be in a suspended state due to the limiting effect of the limiting groove 14, so that the ridge pasting component 18 is prevented from dragging on the ground in the running process of the harvester 1.

when the harvester 1 advances along the ridges and performs harvesting operation, the cutting height is adjusted to be proper, the ridge pasting plate 12 is attached to the ridge surface 3, at the moment, the angle measurer 9 has an initial measurement value, a qualified value range in a certain range is set according to the initial measurement value, if the initial measurement value is 110 degrees, the qualified value range is within a range of plus or minus 3 degrees of 110 degrees;
when the height of the ridge surface 3 is changed, the heights of the ridge attaching plate 12 and the lower measuring arm 7 are changed, so that the first movable arm 6 and the second movable arm 8 are driven to swing, and the measured value of the angle measurer 9 is changed; then the angle measurer 9 feeds back the change condition of the measured value to the control module of the harvester 1, the control module controls the electric push rod to move, the height of the cutting table 19 is adjusted through the electric push rod, the measured value of the angle measurer 9 returns to the qualified value range, and then the cutting height of the cutting table 19 is maintained in a certain range, so that the harvester 1 automatically adjusts the cutting height, and the cutting height of the harvested vegetables is moderate.
In the process that the harvester 1 travels along the ridges, the harvester may encounter the obstacles 4 such as soil blocks or stones, and the height of the header 19 is suddenly changed due to the existence of the obstacles 4, so that the harvesting quality of the vegetables is affected. In the invention, the ridge pasting plate 12 and the lever frame 11 are arranged, and when one end of the ridge pasting plate 12 on one side meets the obstacle 4, the ridge pasting plate 12 and the lever frame 11 are tilted; at this time, the tilting height of the tilting end of the lever frame 11 is smaller than the height of the obstacle 4, the rising height of the lower measuring arm 7 is smaller than the tilting height of the tilting end of the lever frame 11, so that the variation amplitude of the measured value of the angle measurer 9 is reduced, the fluctuation amplitude of the height of the header 19 is reduced, the harvesting height of the header 19 is more stable, and the harvesting quality of vegetables is higher.
