Embodiment Construction

[0040] figure 1 The working element 5 shown in can be advantageously made of a working element called a sowing element 30 having a novel connection structure 31 ( figure 2 )replace. The connection structure 31 comprises a system 34 for adjusting downforce, more simply referred to as adjustment system 34 and referred to Figure 2 to Figure 6 and Figure 7a to Figure 7c to describe.

[0041] The working elements and connecting structure 31 can advantageously be installed in a planter (such as figure 1It is implemented in the shown seeder 1A). The planter 1A is hitched to a tractor not shown. The planter 1A can be pulled, semi-carried or carried.

[0042] The connection structure 31 may generally be implemented in any agricultural machine where the interaction between work implements may require the application of downforce. The agricultural machine may be, without limitation, a single seed planter, a strip tiller, or other type of seeder or tiller.

Abstract

The invention relates to a working element (30) mounted on an agricultural machine, having a deformable connection (31) comprising an upper arm (17) and a lower arm (18), said connection comprising a movable mechanism (35 ; 135) and a system (34; 134) for adjusting downforce of a reference member (36; 136), the mechanism comprising a rod (37; 137) articulated about a first axis (61) and an elastic member (38; 138 ), the mechanism allows: - an engaged state, wherein the mechanism is held against the reference member in the working position, subjecting the working element to a downward force; ) movement, the mechanism includes a second axis (62) about which the lever is pivotable in an intermediate state.

Description

technical field [0001] The present invention relates to the general technical field of agricultural machinery and, in particular, to the field of tillage and / or sowing. Background technique [0002] The present invention relates to any agricultural machine requiring downforce to be applied. Downforce is the ballast force applied to the tool towards the ground to facilitate the interaction between the tool and the ground. The present invention relates, for example, to figure 1 An agricultural machine in , which may be a precision planter or a single seed planter 1A, or a fertilizer distribution machine or a mixing machine. The planter comprises a chassis 2 transverse to the direction of advance, which carries at least one working element 5 . The working element 5 is here referred to as a sowing element 5A, it being understood that it could also be a fertilizer distribution element, a seed and fertilizer mixing distribution element or a tool for working on the ground. The ...
