Problems solved by technology

At present, most of the general rice transplanting machines use a single gasoline engine or diesel engine as the power source, and the power is transmitted to the actuator through the speed change mechanism and the transmission mechanism, while the rice transplanter has many actuators, the motion state is complicated, and the problem of speed change and transmission has always been a problem. One of the difficulties in the field of agricultural machinery design and manufacturing, especially the low efficiency of small and medium power fuel engines, mechanical speed change and transmission mechanism are not easy to simplify, which makes the whole system unfavorable for low carbon energy saving and cost reduction
[0004] In addition, because the existing rice transplanters are all powered by a power mechanism, it is difficult to realize separate control of different transmission mechanisms, and manual assistance is required in situations such as differential speed turning, which is insufficient in flexibility and increases the operator's work. Labor intensity

Embodiment 1

[0029] Such as Figure 1-2As shown, the present embodiment is based on two-wheel 4-row stepping rice transplanter, driven by multiple motors, including rice transplanter frame, two walking water wheel drive motors 13, walking water wheel transmission, walking water wheel 4, A profiling mechanism drive motor 2, a profiling mechanism, a rice transplanting mechanism drive motor 10, a rice transplanting mechanism, a handle 7, a side ship plate 8 and a middle ship plate 12, and the walking water wheel 4 and the side ship plate 8 are all arranged on the rice transplanting The both sides of machine frame walking direction, middle boat plate 12 is arranged in the middle of rice transplanter frame walking direction; Described walking water wheel 4 all links to each other with walking water wheel transmission device, and two walking water wheel drive motors 13 are connected with two respectively. The walking water wheel transmission on the side is connected to each other, and is used to...

Embodiment 2

[0044] Present embodiment except following feature other structures are with embodiment 1: as image 3 As shown, there are two profiling mechanism drive motors 2, which drive the profiling mechanisms on the left and right sides respectively. Displacement sensors or pressure sensors are respectively arranged on the side ship plates 8 on both sides, so as to detect the current displacement or pressure of the side ship plates in real time. Adopting two profiling mechanisms to drive the motor can make the two profiling mechanisms work independently, so that the height can be adjusted separately, and the frame of the rice transplanter can be kept parallel to the mud surface when the paddy field is uneven.

Abstract

The invention discloses a multi-motor driven rice transplanting machine and a control method thereof and belongs to the technical field of new energy agricultural machinery. By adopting power of storage batteries, the invention solves the problems of large size and weight, complicated transmission mechanism, inflexibility in control, high maintenance and running cost, pollutions of noise and waste gas, and the like of a traditional rice transplanter driven by an oil-fired engine; and not only are the above problems solved, but also travelling waterwheel driving motors, a profiling mechanism driving motor and a rice transplanting mechanism driving motor are controlled independently by a controller, so that the functions that the machine turns at a small radius, a profiling mechanism is standby in an energy-saving manner, the distances between transplanted seedlings can be adjusted in a wide range, and the like can be realized. The invention is suitable for China with the practical characteristics of vast population and limited farmland, shortage of energy, large agricultural acreage in mountainous areas and hills, disperse land masses and the like and meets the requirements of the national modern agriculture for novel rice transplanting machines.

Description

technical field [0001] The invention relates to the research field of rice transplanters, in particular to a multi-motor driven rice transplanter and a control method thereof. Background technique [0002] Rice is the grain crop with the largest planting area, the highest yield per unit area, and the largest total yield in my country. Its output ranks first in the world. 60% of the population in China takes rice as the staple food. Rice plays a pivotal role in my country's grain production. Therefore, rice Production mechanization is of great significance. At present, most of the general rice transplanting machines use a single gasoline engine or diesel engine as the power source, and the power is transmitted to the actuator through the speed change mechanism and the transmission mechanism, while the rice transplanter has many actuators, the motion state is complicated, and the problem of speed change and transmission has always been a problem. It is one of the difficulties ...
