Abstract
The device is essentially characterized by the fact that it comprises means for coating a cutting blade (9) with a viscous substance (20) arriving via a channel passing through the blade (9), and means including an anvil blade (84) for pressing the stem to be cut against the cutting edge (10) of the blade (9) in order to simultaneously cut the stem and treat the resulting wound on the stem by coating the wound with the substance (20) which is a treatment substance. The substance (20) is situated in a capsule (19) placed in a handle (13) supporting the cutting blade (9). The device is applicable, in particular, to pruning and treating vines, fruit trees, and other plants of the same type.
Claims12
In a device for simultaneous cutting and treating a plant stem, the device comprising:
- at least one cutting blade (9);
- at least one anvil blade (84) pivotally mounted relative to said cutting blade (9), and including a surface (87) suitable for sliding during rotation over at least a portion of a face (44) of said cutting blade;
- at least one store (19) of treatment substance (20);
- a channel (39) for said substance (20) made through at least a portion of the cutting blade (9) and opening out via at least one orifice (41, 42) situated in a face of said cutting blade;
- means (54, 64) for controlling the transmission of a certain determined quantity of said substance (20) from said store (19) to said orifice (41, 42);
- the improvement wherein said orifice opens within the face of the cutting blade slidable on said surface of said anvil at a given level, and wherein said means for controlling the transmission of said substance comprises means for causing a drop of said substance to be obtained at the outlet from said orifice when said surface (87) of the anvil blade is substantially opposite said face (44) of the cutting blade, and the device includes support means (8, 80) for said cutting blade (9) and for said anvil blade (84) in the form of two handles (13, 83), said two handles being respectively connected to said blades by respective mid-portions (11, 82), with rotation of said blades being driven about a rotary shaft (3) passing through said mid-portions, said store (19) being situated in a housing (17) provided in the handle (13) connected via one of said mid-portions (11) to said cutting blade (9), via a channel (39) having a portion (47) passing through said mid-portion (11) in order to connect said store (19) to said orifice (41, 42) provided in said cutting blade (9), whereby rotation of the cutting blade is effected with respect to the anvil blade such that the two surfaces (44, 87) of the blades, respectively overlap sufficiently that the orifice is partially or totally covered by anvil blade surface (87), thereby preventing treatment substance loss, minimizing consumption of treatment substance and insuring treatment application to the cut stem applied each time a cut is made.
