Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0031] Such as figure 1 As shown, a crawler-type combine harvester header operating state monitoring system according to the present invention includes a monitoring device 1 on the right side of the header for monitoring the shaft end on the right side of the header, and a monitoring device 1 for monitoring the feeding end of the conveying trough. The monitoring device 2 at the feeding end of the conveying trough, and the monitoring device 3 on the left side of the header for monitoring the left shaft end of the header. The monitoring device 1 on the right side of the header, the monitoring device 2 on the feeding end of the trough and the monitoring device 3 on the left side of the header all include the same monitoring unit and a plane mirror b corresponding to the moni...

The invention provides a monitoring system and monitoring method for the operation status of a crawler-type combine harvester header. The devices all include a monitoring unit and a plane mirror b installed in the cab. The monitoring unit includes a convex lens a, a plane mirror a, a concave mirror, a convex lens b and a convex lens c. The light is focused on the position to be monitored through the convex lens a, and the light reflected from the position to be monitored enters the concave mirror , the light gathered by the concave mirror enters the convex lens b after being reflected by the plane mirror a, the light emitted from the convex lens b enters the convex lens c, the light emitted from the convex lens c is reflected to the plane mirror b by one or more plane mirrors c, the present invention gets rid of the traditional The power supply, sensor, algorithm, control system, etc. required for the monitoring method have a simple structure and low cost, and the operator can intuitively understand the working status of each part of the header.
Description
technical field [0001] The invention relates to the technical field of monitoring the working state of agricultural machinery, in particular to a monitoring system and a monitoring method for the working state of a crawler combine harvester header. Background technique [0002] The working environment of the combine harvester is very harsh when harvesting in the field. When it works, the grain is first guided to the cutter by the reel, and the cutter cuts the grain, and then the crop is transported to the inclined conveying trough by the feeding auger. During the harvesting process, it is difficult for the operator to observe the working status of the various parts of the header. The harsh working environment often causes grain blockage at the shaft end of the rotating shaft, which reduces the rotating shaft speed, which leads to a great reduction in the working performance and harvesting efficiency of the combine harvester. , so it is very important to realize the monitorin...
