Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of facility agriculture micro ploughs, and specifically relates to a multi-motor electric micro plough. BACKGROUND

[0002] Micro ploughs are suitable for small-scale farmland and family farms, and can effectively replace labor, improve labor efficiency, and reduce production costs. At the same time, they improve soil quality and achieve precision farming, promoting agricultural modernization. In addition, the lightweight design of micro ploughs reduces soil compaction, has environmental advantages, and is supported by policies to promote its application. Its multifunctionality and ability to adapt to complex terrain make it have broad application prospects in Chinese agricultural production.

[0003] Existing micro ploughs are mostly driven by internal combustion engines, resulting in high noise and serious harmful gas emissions during work, causing environmental pollution. In addition, they usually rely on traditional control methods such as mechanical joysticks or pedals, which are difficult to operate and require high technical level of operators. Moreover, some micro ploughs use human power to control the forward movement of the machine body, and the rotary tiller device rotates in coordination with the auxiliary wheel to work, with the tiller depth being limited. The force generated by the tiller rotating in the soil can cause vibration of the vehicle body and difficulty in operation, seriously affecting the tillage effect. For example, Chinese patent application CN114514804A discloses a walking device composed of a hand-pushing mechanism and a rolling mechanism, and a power device composed of a power output shaft and a tillage device. Although the machine body structure is simple and lightweight, the operator needs to continuously exert physical effort to maintain the balance of the machine body and push the vehicle body forward and backward during operation, making the machine body inconvenient to operate. These problems not only affect the sustainability of agricultural production, but also limit the popularity and use efficiency of micro ploughs.

[0004] Electric micro ploughs use power batteries as energy sources and electric motors as driving devices, which reduces carbon emissions during work compared to internal combustion engines. The noise generated by electric motors during work is much lower than that of internal combustion engines, making them suitable for work environments that require a quiet environment. Moreover, electric motors have less wear and tear on their working parts, have a long service life, and can promote the development of green agricultural equipment, which is conducive to the sustainable development of agricultural production and the realization of carbon neutralization. Electric micro ploughs can automatically and accurately adjust the speed and torque of the electric motor through a microcontroller according to the needs of the work, responding quickly and efficiently. In addition, electric micro ploughs can use a control panel to achieve control, reducing the difficulty of operating the micro plough and making it convenient and flexible to operate. With the continuous progress of technology and the increasing market demand, electric micro ploughs will play a greater role in future agricultural production. SUMMARY

Then, the drive wheel start button and the tiller start button on the control panel are used to start each motor. When the forward or reverse button is pressed, the machine controller processes the data fed back from the motors to adjust the actual speed of the machine, reducing the deviation between the actual and expected speeds. The rotary switch can be used to adjust the forward speed of the drive wheels and the speed of the tiller motor. When the machine needs to turn, pressing the left or right turn switch will set the speed of one drive wheel motor to 0, while the other motor operates at the set speed, thus enabling turning. During turning or reversing, the tiller motor speed is 0 to avoid injury to the tilled land or the operator. The forward and reverse rotation buttons on the tiller can be used to change the rotation direction of the tiller. The machine's working data can be monitored in real time on the display screen on the control panel.
