The stubble height detection device 311 comprises a linear displacement sensor which is arranged on a lifting hydraulic oil cylinder 313 and is connected with the control system 32.
The hydraulic system of the rice combine harvester used daily at present is relatively simple in structure, mainly comprises a hydraulic oil tank, a hydraulic pump, an overflow valve, a manual reversing valve, a control handle, a hydraulic cylinder and the like, and in the operation process, a driver needs to observe the height of the header 1 in real time and adjust the height of the header 1 by using the control handle, so that the labor intensity is high, and the requirement on the proficiency of the driver is high. The harvester adopting the height adjusting system 31 adopts the second electromagnetic reversing valve to replace a manual reversing valve, and is driven by a relay controlled by a PLC controller. In the system, the lifting hydraulic oil cylinder 313 is a single-acting cylinder, and when the height needs to be lowered, the header 1 can be lowered by self weight.
The plant height recognition device 312 can detect the height of rice in real time during the operation of the harvester, and the detected height information is used as the basis for the next header 1 action. The height adjusting system 31 mainly realizes the accurate positioning of the position height of the header 1 through the feedback value of the stubble height detecting device 311, and the lifting hydraulic cylinder 313 has the function of realizing the lifting of the header 1 so as to simultaneously keep the header 1 at a certain position height. The harvester height adjusting system 31 mainly comprises the steps of signal input, algorithm analysis, control output and the like in the working process, and the basic working principle is as follows: in each control period, the plant height recognition device 312 detects the current crop height, and the PLC controller analyzes the detected crop height and the given input parameters to obtain the target adjustment height of the header 1. And then, the stubble height detection device 311 is used for determining the height of the current header 1 through conversion relation, so that the height adjustment amount of the header 1 is further analyzed and obtained by combining the target adjustment height. And finally, the PLC controls the lifting hydraulic oil cylinder 313 to realize the lifting of the header 1 by changing the closing time length and the closing direction of the second electromagnetic directional valve.
The second electromagnetic directional valve adopts an M-shaped electromagnetic directional valve, and the working voltage of coils on two sides of the second electromagnetic directional valve is 24V. When the second electromagnetic directional valve is in the middle position, the working oil port A, B is closed, the oil inlet P is directly connected with the oil return port T, and the header 1 can be kept in a static state at the moment. The P port of the second electromagnetic directional valve is connected with an oil inlet pipe, the A, T port is connected with an oil tank, and the B port is connected with an oil inlet pipe of a hydraulic cylinder for controlling the header 1 to lift. When the header 1 needs to descend, the left coil of the second electromagnetic directional valve closes the valve core and moves left, A is communicated with P, and B is communicated with T. When the header 1 needs to be lifted upwards, the closed valve core of the right coil of the second electromagnetic directional valve moves rightwards, P is communicated with B, and A is communicated with T. When coils on two sides of the second electromagnetic directional valve are not electrified, the valve core is located at the middle position, A is communicated with T, oil in the oil inlet directly returns to the oil tank, and the header 1 is static. The stubble height detection device 311 is installed on the side of the lifting hydraulic cylinder 313. The stubble height detection device 311 is driven to extend and contract by the movement of the lifting hydraulic oil cylinder 313.
The infrared diffuse reflection photoelectric sensor 3211 is strong in anti-interference capability, simple to install and 80cm in effective detection distance. The sensor mounting plate 3212 is made of an acrylic material and has the advantages of high strength, light weight and the like. The traditional ground profiling device needs to ensure that the header 1 is tightly attached to the ground, the height of the infrared diffuse reflection photoelectric sensor 3211 can be set to any value within the range of 0-600mm, and the effective detection distance of the infrared diffuse reflection photoelectric sensor 3211 is 80cm, so that the device is suitable for rice harvesting and ratoon rice harvesting. In the operation process, the infrared diffuse reflection photoelectric sensor 3211 does not receive a reflected signal when not blocked by rice plants in the identification range, and outputs a high level signal, otherwise outputs a low level signal. During detection, low-level signals are searched from top to bottom, and whether the output signal state of the sensor is consistent with the previous state or not is judged again after the simultaneous delay of 500ms is found. If yes, the height of the infrared diffuse reflection photoelectric sensor 3211 is the height of the current rice plant.
