Marking method and device for keeping row distance in process of carrying out rice planting or direct-seeding traveling

Abstract

The invention relates to a marking method and device for keeping a row distance in the process of carrying out rice planting or direct-seeding traveling. A base is provided with a marking seat with an elastic automatic reset function. A marking rod is connected to the marking seat. The marking rod can rotate around the marking seat. The marking seat is provided with a disk with a torsional spring. The excircle of the disk is provided with a disk trough. A cable assembly is embedded in the disk trough. The cable assembly is directly connected to an operating rod of a cab. The marking device is regulated through the operating rod of the cab. When an operator tensions the operating rod, a cable pulls the disk of the marking seat to rotate around a shaft, and the torsional spring is compressed to drive the marking rod inserted in the marking seat to rotate downwards; and when the operating rod is tensioned in place, the marking rod is just in a horizontal state and the inclination degree of the marking rod is regulated so as to carry out marking in a formed paddy field. Conversely, the operating rod is released, the disk of the marking seat rotates around the shaft under the action of an elastic force of the torsional spring so as to drive the marking rod to rotate upwards; and when the operating rod is released in place, the marking rod is in a vertical state, namely a folding state.

Description

Technical field [0001] The invention relates to an agricultural operation method and its mechanical components and devices, in particular to a marking method and device for maintaining the row spacing during rice transplanting or direct seeding work, especially the operator can carry out the retractable marking in the cab Wire method and device. Background technique [0002] Rice transplanter is currently a very common agricultural operation machine for agricultural mechanization. Because of its high efficiency and labor intensity, it is much smaller than the previous manual transplanting, so it is very popular with farmers. The rice transplanter includes a number of components, including a scribing device that maintains the row spacing. [0003] At present, the marking device of the rice transplanter seen in the market is movably connected to the machine base. When transplanting rice in a leveled paddy field, the operator needs to leave the cab to adjust the height of the marking...
