Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, a wetland driving operation device provided by the embodiment of the present invention can be used for farming, transportation and other operations in wetlands such as paddy fields. According to the general understanding, wetlands refer to natural or artificially formed swamps with static or flowing water bodies. Areas of shallow water, including areas where the water depth at low tide does not exceed 6 meters. Paddy fields belong to constructed wetlands in wetland ecosystems. In this embodiment, a paddy field tractor used in paddy fields is taken as an example. The above-mentioned working device for driving on wet ground includes a main body 1 and driving wheels. The working device for traveling on wet ground in this embodiment is provided with front wheels 21 and rear wheels 22, and at least one set of the front wheels 21 and the rear wheels 22 serves as driving wheels. Front wheel 21 and rear wheel 22 (drive wheel) are conn...

Embodiment 2

[0043] image 3 It shows the implementation flow of the driving control method of the wetland driving operation device provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0044] The embodiment of the present invention is applicable to the wetland driving operation device in the first embodiment, specifically, it is applicable to the DSP controller in the wetland driving operation device to prevent the wetland driving operation device from slipping. The driving control method specifically includes:

[0045] In step S301 , monitor the current slip ratio of the wetland driving operation device in the current paddy field, and determine whether the monitored current slip ratio is within a preset reference range of the optimal slip ratio for the current paddy field.

[0046] The optimal slip ratio reflects the best state of the wetland driving operation device in the c...

Abstract

The invention is applicable to the technical field of agricultural machinery, and provides a wetland travel operation device and a method for controlling the same. The wetland travel operation devicecomprises a body, driving wheels and driving wheel slip rate control devices. The driving wheels are connected to the body, the body is provided with paddy field mud water film depth monitoring devices for monitoring the depths of mud water films of paddy fields, the body or at least one of the driving wheels is provided with wheel speed sensors, the wheel speed sensors are used for monitoring thespeeds of the driving wheels, and the body is further provided with a speed adjusting device and an actual vehicle speed sensor for monitoring the travel speeds of the wetland travel operation device. The wetland travel operation device and the method in an embodiment of the invention have the advantages that the wetland travel operation device is high in intelligence degree, machinery and traction power can be adjusted without dependency on experience of drivers, slipping can be prevented or relieved, and excessive slipping of the driving wheels of the wetland travel operation device, overload of transmission systems and damage on the transmission systems and abrasion of tires due to excessive slipping of the driving wheels and overload of the transmission systems can be prevented; the wetland travel operation device is high in traction efficiency and favorable for protecting hard bottom layers of the paddy fields, energy can be saved, and environments can be protected.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a wetland driving operation device and a control method thereof. Background technique [0002] my country's paddy field area is about 30 million hectares, which provides the main guarantee for my country's food security. However, the paddy field operation environment is complex, the muddy water depth is different, and the mud foot adhesion is different. The tractor used as the power source in the paddy field operation often slips severely, requiring the driver to adjust the tractor throttle, gearbox gear and implements for a long time to adapt. This will further deepen the mud foot of the paddy field, causing great damage to the hard formation of the paddy field. At the same time, the fuel consumption of the tractor is increased, and the life of the tire or crawler is shortened. [0003] At present, traditional upland tractors are still used for paddy ...
