In the process of agricultural modernization, the operating efficiency and labor intensity of rice and wheat thresher directly affect the quality and cost of grain harvest. How to achieve the coordinated optimization of the two has become a key issue to improve agricultural production efficiency and promote the development of agricultural mechanization. By improving the equipment structure, operation process and other aspects, the labor burden of farmers can be reduced while improving the operating efficiency.
The core structure of rice and wheat thresher is a key factor affecting operating efficiency and labor intensity. Optimizing the speed, diameter and arrangement of the threshing drum can effectively improve the threshing efficiency. For example, the use of variable diameter drum design can achieve a more reasonable threshing force distribution during the threshing process according to the different characteristics of rice and wheat crops, reduce grain breakage, and improve the threshing rate. At the same time, optimizing the structure of the feeding device, such as using a spiral feeding mechanism, can achieve uniform and continuous feeding, avoid frequent manual adjustment of the feeding amount, and reduce labor intensity. In addition, improving the cleaning device, using a combination of multi-layer screens and airflow cleaning, can quickly separate grains and impurities, and reduce the workload of manual secondary cleaning.
The performance of the power system directly determines the operating efficiency of rice and wheat thresher. The use of high-power, low-fuel-consumption engines and optimized transmission ratios can ensure the stable operation of rice and wheat thresher under different working conditions. For example, the introduction of variable frequency speed regulation technology can adjust the speed of the threshing drum in real time according to the maturity and humidity of the crops, while ensuring the threshing quality and improving the operating efficiency. At the same time, upgrading the traditional belt drive to chain drive or gear drive can reduce the slippage during power transmission, improve transmission efficiency, and reduce the labor intensity caused by fault maintenance. In addition, it is equipped with a hydraulic lifting system to facilitate loading and unloading and transportation, and reduce the burden of manual handling.
The application of intelligent technology is an important direction of collaborative optimization. Sensors are installed on the rice and wheat thresher to monitor parameters such as feed volume, threshing load, and grain moisture content in real time, and the operating status of the equipment is automatically adjusted through the control system. For example, when the sensor detects that the feed volume is too large, the system automatically reduces the feed speed to avoid blockage and ensure the continuity of operation. At the same time, remote monitoring and fault diagnosis functions are developed, and farmers can view the working status of the rice and wheat thresher in real time through the mobile phone APP. Once a fault occurs, the system will promptly alarm and provide solutions to reduce maintenance time and labor intensity. In addition, the automated grain collection and packaging device can realize automatic bagging of grains without frequent manual handling, further improving work efficiency.
Good ergonomic design can significantly reduce labor intensity. Optimize the layout of the rice and wheat thresher operating platform, set the operating buttons and dashboard in a position that is easy to observe and operate, and reduce the operator's line of sight and body movement. Use shock-absorbing seats and armrests to reduce fatigue caused by long-term operation. At the same time, design reasonable maintenance channels and inspection ports to facilitate daily maintenance and fault repairs, and reduce the labor intensity during maintenance. In addition, in the appearance design of the equipment, add guardrails and anti-slip pedals to ensure the safety of operators, so that they can work more attentively and efficiently.
The skill level and operating specifications of operators have an important impact on work efficiency and labor intensity. Strengthen the training of operators so that they are familiar with the performance, operation methods and maintenance points of rice and wheat thresher, can correctly adjust equipment parameters, and deal with common faults in a timely manner. At the same time, establish a scientific operation management process, arrange operation time and tasks reasonably, and avoid inefficiency and increased labor intensity caused by improper operation or chaotic processes. For example, formulate standardized feeding, threshing, and cleaning operation processes to ensure close coordination of all links and improve overall operation efficiency.
To achieve the coordinated optimization of rice and wheat thresher operation efficiency and labor intensity, it is necessary to take comprehensive measures from multiple aspects such as mechanical structure, power system, intelligent control, ergonomic design, and personnel management. Through technological innovation and management optimization, it can not only improve agricultural production efficiency, but also effectively reduce the labor burden of farmers and promote agricultural mechanization to a higher level.
