摘要:
Device for distributing seeds for a sowing machine, which comprises a rotor (2) peripherally provided with a plurality of equidistant cells (3) each adapted to contain a dose of seeds to be distributed, a stator (4) placed externally around the rotor (2) and provided with a first opening (5) in order to cyclically feed the cells (3) with doses of seeds, and a second opening (6) in order to receive the doses of seeds from the cells (3) and to cyclically discharge them. The distribution device also comprises an elastically pliable bottom wall (7) inserted within the cell (3); elastic means (8) being provided for connecting the bottom wall (7) to the rotor (2). The bottom wall (7) defines, together with a lateral wall (9) of the cell (3), a metering chamber (10) for containing the seeds.
摘要:
This invention relates to a machine designed to perform a complete spray treatment of agricultural land by incorporating in the soil liquid substances such as plant protection products, weedkillers, fertilisers and soil conditioners. The machine according to the invention is suitable in particular for treatments, such as fumigation of agricultural land, which involve incorporating into the soil liquid substances that subsequently evaporate and perform their function in the gaseous state. Said machine is characterised in that it comprises first means (3) designed to spray said soil and second means (5) designed to compact said sprayed soil, thus creating a compact crust which obstructs the escape of the vapours generated by the evaporation of said liquid sprayed by said first means (3). According to a preferred embodiment, the machine of the invention, further comprises third means (8) designed to till the soil positioned immediately downstream of said first spraying means (3) and upstream of said second compacting means (5).

Sowing machine for distributing seeds on the ground which comprises a support frame, at least one containment hopper (4), at least one sowing unit (5) provided with at least one distribution disc (7), distribution means (9) for receiving the seeds from such hopper, and cyclically in communication with the distribution spouts (8) in order to release a dose of seeds at their interior, first motorization means (10) connected to the distribution disc (7) in order to rotate it around a rotation axis (X) substantially orthogonal to the advancement direction of the sowing machine (1), the distribution means (9) comprise a rotor (11) peripherally provided with a plurality of equidistant cells (12), each adapted to contain a dose of seeds to be distributed, second motorization means (17) connected to the rotor (11) in order to rotate it so to cyclically face said cells (12) at a first opening (14), a logic control unit (18) electrically connected to the first motorization means (10) and to the second motorization means (17), which controls the first motorization means (10) and the second motorization means (17), synchronizing the position of the distribution spouts (8) and of the cells (12) at the second opening (15).
摘要:
The present invention concerns a method for the fumigation treatment of agricultural lands and a machine, for carrying out such method. These method and machine are adapted in particular to perform such land fumigation treatment at a greater depth than the one reached by tools for plowing the land and for earthing big-sized stones and clods. The machine of the invention comprises anchors (4) adapted to open a lenticular recess (6) in the land and sprayers (5) adapted to spray liquid fumigating substances in the lenticular recess (6), these anchors making the lenticular recess (6) without overturning the above land, so that the recess (6) closes itself after the spraying of liquid fumigating substances, preventing the dispersion in the atmosphere of fumes produced by the liquid fumigating substances.
摘要:
This invention relates to a device designed to distribute liquid products precisely in agricultural land so that they are positioned in a layer situated a few centimetres below the surface, depending on the type of product to be sprayed, the crop, and the nature of the soil. Said liquid products can contain weedkillers with an anti-sprouting action or other substances with a herbicidal, fungicidal, insecticidal, hormonal, fertilising or soil-conditioning action. Said device is of the type fitted with a plurality of nozzles (6) positioned on support means (2) placed above the soil to be sprayed, which said nozzles spray said liquid substances on the soil while said support means, which are mounted on a towing machine, are moved above said soil. The device is characterised in that it includes first means (5a,5b,5c) designed to allow the advance of said nozzles (6) in said soil in such a way that said nozzles (6) spray said liquid substances directly below the surface of said soil, second means being fitted which are designed to regulate the vertical position of said nozzles (6) so as to regulate the depth at which said liquid substances are sprayed.

Mulching machine for laying a covering cloth over a ground, which comprises a reel (3) of a covering cloth (4), laying means (6) adapted to lay on the ground a strip (7) of the covering cloth (4) and earthing up means (8) adapted to at least partially bury the strip (7) of covering cloth (4), such earthing up means (8) comprising a roller (9) and a plurality of teeth (10) removably fixed to the roller (9) and radially projecting outside the latter. The mulching machine also comprises first movement means (13) and second movement means (14), which are respectively adapted to move the roller (9) between an interference position, in which the teeth (10) plunge into the ground, and a non-interference position, in which the teeth (10) are lifted from the ground, and to rotate the roller (9) into a first or into a second rotation sense (V1, V2) in order to bring the teeth (10) to intercept the ground and to turn it over so as to bury the strip (7) of covering cloth (4). The mulching machine also comprises a logic control unit (15) configured for driving the first and the second movement means (13, 14) to execute earthing up operations.
