Field operation machine for wetland

Abstract

The invention discloses a field operation machine for a wetland. The field operation machine comprises a walking device and an operation device, and is characterized in that a floating body part of the walking device is coaxially connected with a bridging device, the floating body part comprises a first driving wheel and a second driving wheel which are symmetrically arranged at two ends of the bridging device, the first driving wheel is connected with a first driving motor, and the second driving wheel is connected with a second driving motor; the operating device is fixed on the bridging device, and the center of gravity of the operation device is positioned below the center shaft of the first driving wheel and the second driving wheel; and the diameters of the first driving wheel and the second driving wheel are more than 50cm. The field operation machine provided by the invention simplifies the structure of the walking device, so that the requirements of handy and convenient fieldoperation are met.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery automation, and more specifically relates to a field operation machine for wetlands. Background technique [0002] Existing agricultural machinery includes a traveling device and an operating device, thereby possessing the functions of walking and operating in the field. In order to keep walking balance and steering, the walking device includes 3 or 4 wheels, a part is a guide wheel, and a part or all of the wheels are driving wheels. The above-mentioned agricultural machinery has the characteristics of stable walking and large load capacity, but its own weight is not easy to reduce, its turning radius is large, and its walking flexibility is poor, so it is not suitable for some light operations in the field, such as sowing and transplanting of young seedlings. [0003] At the same time, the paddy field is a wetland, and its operating machinery must also meet the requirements of wa...

AI Technical Summary

Problems solved by technology

The above-mentioned agricultural machinery has the characteristics of stable walking and large load capacity, but its own weight is not easy to reduce, the turning radius is large, and the walking flexibility is poor, so it is not suitable for some light operations in the field, such as sowing, seedling transplanting, etc.

[0003] At the same time, the paddy field is a wetland, and its operating machinery must also meet the requirements of walking on the wetland. The existing paddy field machinery is generally driven by wheels or crawlers. To drive the machine forward, it is easy to cause the bottom soil of the field to be continuously destroyed, and the mud foot of the field is also deepened year by year, making it more and more difficult for the machinery to walk and operate in the rice field

[0004] Patent document CN2016101395271 discloses an electric plant protection vehicle utilizing the principle of a balance vehicle. It is driven by a battery and walks on two wheels. It has the advantages of automatic balance and flexible turning. High and small wheels, it is not suitable for field walking conditions; at the same time, it is necessary to set up a counterweight medicine box and a buffer medicine box to ensure the balance of the center of gravity of the vehicle body, which makes the weight of the whole vehicle too large, which is difficult to apply in rice fields
