Embodiment
[0024] Such as figure 1As shown, the present embodiment includes an up and down guiding system, a front and rear guiding system, a suspension system, a probe rod, and a signal processing system. The upper and lower guide system includes two groups of upper and lower guide rails 8, and the top of the guide rails is fixed on the car body for height adjustment of the probe rod 1 before operation. The front and rear guide system includes two front and rear guide rails 6 and guide wheels 5. The front and rear guide rails 6 are fixed in the upper and lower guide rails 8. The upper and lower guide rails 8 have a series of screw connection holes with adjustable positions. The center distance is 25mm, which realizes that the front and rear guide rails 6 are fixed at different positions in height. Guide wheel 5 is installed in the groove of front and rear guide rail 6 both sides, is used for reducing the resistance between suspension system and front and rear guide system. The front a...

The invention relates to a field locomotive circulation walking device with a navigation location processing system, belonging to the technical field of agricultural machines for field operation. The field locomotive circulation walking device with the navigation location processing system comprises an up and down guidance system, a front and back guidance system, a hanging system, probe rods and a signal processing system, wherein the front and back guidance system is fixed on the up and down guidance system, the upper half part of the hanging system is sleeved on the front and back guidance system and arranged on a same plane with the front and back guidance system, the lower end of the hanging system is connected with the probe rods through a hinge and arranged at the lower front part of the front and back guidance system, the amount of the probe rods is two, the probe rods are arranged at the bottom of an integral device and connected with the lower end of a bearing rod of the hanging system through a hinge, the signal processing system is provided with two angle displacement sensors, and the two angle displacement sensors are respectively installed at two hinges used for connecting the up and down guidance system with the hanging system. The invention has the advantages of low cost, simple process and simple structure, can acquire yawing signals through a set of probe rod devices and realize accurate circulation walking of a field locomotive, thereby avoiding crop loss in the circulation walking process of the field locomotive.
Description
technical field [0001] The invention relates to a device in the technical field of agricultural machinery for field operations, in particular to a device for walking a field locomotive with a navigation and positioning processing system. Background technique [0002] When working in the field, in order to avoid crushing the crops as much as possible during the walking process of the agricultural machinery, it is required that the agricultural machinery can walk along the crop ridges. However, due to the luxuriant branches and leaves in the middle and late stages of crop development, it is difficult for drivers to observe the gap between rows. Therefore, it is of great significance to use autonomous navigation technology to guide agricultural machinery to walk along the crop row. More mature navigation methods mainly include inertial navigation, laser navigation, magnetic navigation, infrared navigation, satellite navigation, etc. These navigation methods can achieve high po...
