Embodiment Construction
[0016] The present invention will now be further described with reference to the drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0017] Such as Figure 1 ~ Figure 5 The farmland working machine shown here, taking the rice transplanter as an example, includes a body 1, two front wheels 2 supporting the front of the body 1, four rear wheels 3 supporting the rear of the body 1, and for convenience of description, The two outermost rear wheels 3 of the four rear wheels 3 are defined as outer rear wheels 31, and the middle two rear wheels 3 are inner rear wheels 32. A planting device 6 is provided in the middle of the body 1, and a seedling box is located above the planting device 6 The supply device 9 is provided with a seedling stand 10 located above the middle of the body 1, a driv...

The invention discloses an agricultural operation machine which comprises a machine body, two front wheels for supporting the front part of the machine body, four rear wheels for supporting the rear part of the machine body and a driver seat with a pedal, wherein the middle of the machine body is provided with a planting device, and the two rear wheels at the outmost side are respectively positioned at two sides of the planting device; the two rear wheels at the innermost side are respectively provided with a lifting device used for lifting the rear wheels at the outmost side when the machinebody slews; and the lifting devices are controlled by the pedal to operate. When the agricultural machine provided by the invention operates in a manner of slewing along the ground in the field, the agricultural machine can slew by taking the rear wheels at the outer side as supporting points, and the lifting devices are utilized to lift up the rear wheels at the outer side, so that the rear wheels at the outer side are suspended above the soil, overweight loads are not generated on the soil (or loads are reduced), and seedling collapse caused by soil caverns or soil stacks caused when the machine body slews can be prevented, therefore, when the machine body slews, U-shaped steering can be completed by one action without turning the machine body, and the operating efficiency is improved.
Description
Technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a farmland working machine that can rotate freely without damaging the soil. Background technique [0002] Farmland operation machines, such as rice transplanters, lawn mowers, etc., rely on the back and forth of the front wheel and the rear wheel to perform field operations. Generally, for this type of work machine, due to the softness of the soil when walking, there are four rear wheels, and the two outermost rear wheels are on the outside of the planting device. When working in the field, it is necessary to rotate the body on the pillow ground between the planting area and the ridge, and use the rear wheel on the inner wheel side as a fulcrum to make a U-shaped turn, so that there is no need to adjust the body to the next row of planting positions. As a result, the soil at the location of the rear wheel that becomes the fulcrum is subjected to excessive load or dist...
