Embodiment Construction

[0014] A variable width telescoping chassis (1) shown in Figure 1 supports a working tool (2). A telescoping undercarriage (1) for an agricultural implement (3) such as a seed drill comprises a central beam (4) and at least one sliding extension (5, 6) on each side. Preferably, the central beam (4) is hollow. The telescopic chassis (1) can be converted from the smallest size to the largest size and vice versa by sliding the extensions (5, 6) inside the center beam (4). To reduce the size of the chassis (1), the sliding extensions (5, 6) are telescopically retracted into the center beam (4), and in turn, to increase the size, the sliding extensions (5, 6) are retracted inside the center beam (4 ) sticks out. The telescoping chassis (1) is hollow and preferably has a polygonal cross-section preventing the rotation of the sliding extensions (5, 6) relative to the central beam (4). The shape of the section is square, rectangular, or the known H-shape.

Abstract

The invention relates to a telescopic chassis (1) with changeable width used for farm implement (3). The chassis comprises a central beam (4) and at least one sliding lengthened piece (5,6) on each side. The telescopic chassis (1) supports operation tools (2) distributed with a certain adjustable distance, while the distance between the operation tools is in the minimum value, the dimension of the telescopic chassis (1) is also reduced; and the central beam (4) has the similar length with the telescopic chassis (1) while it is in the position of reduced dimension. The telescopic chassis (1) is characterized in that: the length of each sliding lengthened piece (5,6) is essentially equal to that of the central beam (4). The invention further relates to farm implements equipped with the at least one such telescopic chassis (1).

Description

technical field [0001] The invention relates generally to the technical field of agricultural machinery. In particular, it relates to a variable width telescopic undercarriage for agricultural implements, comprising a central beam and at least one sliding extension on each side, said telescopic undercarriage supporting work distributed at defined and adjustable spacing tools, the telescoping chassis also has a reduced size when the spacing between the work tools is at a minimum, and the central beam has a length substantially similar to that of the telescoping chassis in a reduced size state . The invention is applied to the fields of seed drills and precision seeders. Generally, the invention relates to agricultural machinery for working on parallel lines or rows spaced apart by a certain distance. Background technique [0002] A telescopic chassis such as this is already known to those skilled in the art from document FR2862181. The telescoping undercarriage is loaded ...
