Problems solved by technology

[0002] In the prior art, most combine harvesters are not equipped with a device for real-time monitoring of the impurity content and damage of the grain in the combine harvester. The damage rate is calculated manually, and the impurity rate is calculated by manual weighing. Therefore, It is also impossible to automatically adjust the operation according to the feedback information of the damage rate and impurity rate, which affects the efficiency of production operations
[0003] The most relevant prior art to the present invention is the patent titled "Real-time Monitoring Device for Grain Impurity and Breakage Rate of Combined Harvester Grain Box" (Patent No.: 201820058732. After the grain (grain) sampling, it is a static shooting, and the grain (grain) in the grain tank needs to accumulate to a certain weight before sampling and shooting, the grain monitoring effect is not ideal

[0027] Grain Sampling Monitoring Device for Combine Harvesters

[0028] Such as figure 1 As shown, the grain elevator 3 is included, and the grain elevator 3 is installed on the combine harvester, and is used to transport the processed grain (grain) from the cleaning room located at the lower part of the combine harvester to the upper part of the combine harvester. The grain tank, this is prior art.

[0029] Such as figure 1 As shown, the upper side of the grain elevator 3 is connected to the upper end of the upper chute 4, the upper chute 4 is arranged obliquely, and the lower end of the upper chute 4 is connected to the sampling device, and the top of the sampling device is provided with a camera 6 and light supplement The light 8, the photographing camera 6 and the fill light 8 are fixed on the camera bracket 7. During implementation, two supplementary lights 8 are fixed on both sides of the camera bracket 7 , and the photographing camera 6 is fixed between the two suppl...

[0033]Control method of grain sampling monitoring device for combine harvester

[0034] When the speed of the grain elevator is normal, the vehicle control unit controls the sampling device to take samples; the camera captures the image of the sampled grain, and the image analysis and processing unit analyzes and processes the captured image, marking the image as containing impurities and damaged grains, and the vehicle control unit according to The analysis and processing results monitor the impurity rate and breakage rate of the grains; when the rotation speed of the grain elevator is abnormal, the vehicle control unit controls the sampling device to stop sampling. When the camera captures the image of the sampled grains, the control unit of the whole vehicle controls to turn on the supplementary light.

[0035] The control process is detailed below:

[0036] When the processed grain (grain) is transported to the grain tank by the grain elevator 3, the grain elevator 3 rota...

Abstract

The invention relates to a grain sampling and monitoring device for a combine harvester and a control method for the grain sampling and monitoring device. The grain sampling and monitoring device comprises a grain elevator (3), wherein a sampling unit is integrally and fixedly arranged on a punching plate located at the outer side of the grain elevator (3); the upper side of the grain elevator (3)is connected with the upper end of an upper chute pipe (4); the upper chute pipe (4) is obliquely arranged; the lower end of the upper chute pipe (4) is connected with the sampling unit; a shooting camera (6) is arranged above the sampling unit and connected with an image analyzing and processing unit; and the image analyzing and processing unit is connected with a vehicle control unit. Accordingto the invention, directed at sampling and monitoring of processed grains (grains) in the grain elevator, the situation that the grains (grains) need to be accumulated to a certain weight to be sampled and shot is avoided; continuity and continuity are achieved in the sampling process; and the effect of real-time grain monitoring is effectively guaranteed.

Description

technical field [0001] The invention relates to a grain sampling monitoring device for a combine harvester and a control method thereof. Background technique [0002] In the prior art, most combine harvesters are not equipped with a device for real-time monitoring of the impurity content and damage of the grain in the combine harvester. The damage rate is calculated manually, and the impurity rate is calculated by manual weighing. Therefore, It is also impossible to automatically adjust the operation according to the feedback information of the damage rate and impurity rate, which affects the efficiency of production operations. [0003] The most relevant prior art to the present invention is the patent titled "Real-time Monitoring Device for Grain Impurity and Breakage Rate of Combined Harvester Grain Box" (Patent No.: 201820058732. After the grain (grain) sampling, it is a static shooting, and the grain (grain) in the grain box needs to accumulate to a certain weight befo...
