DEVICE FOR APPLICATION OF HERBICIDES INTO NEAR-TRUNK AND INTER-TRUNK BAND OF GARDEN

摘要

A device for application of herbicides into a near-trunk and inter-trunk garden band is proposed. It comprises a front bar, a rotary level, a boom with flat-jet sprayers, a probe and a protecting case. The rotary level is made as a crossbeam, a short shoulder of which is hingedly connected to a link of varying length, the other end of which is hingedly connected to the front bar, a spray section which comprises a boom with flat-jet sprayers and a protecting case, and also the probe and the front bar form together a hinged parallel-link motion. The probe and a rotary lever is correspondingly outer and internal longitudinal rotary links thereof. In doing so the link of varying length comprises a resilient element due to which length thereof can be increased under the effect of stretching forces and return to the previous size while the action thereof is stopped. In addition, the outer longitudinal link (the probe) is supported by ball-and-socket joints, and the spraying section is connected to a cylindrical joint of the internal longitudinal rotary link (a rotary level) through a mechanism for regulating position thereof in the horizontal and transversal vertical planes.
