Definitions

  • the present invention relates to the agricultural sector of tilling land, and in particular constitutes an improvement of a reversible single-furrow plough mounted, by direct attachment, to the tractor, equipped with subsoilers.
  • a non-reversible single-furrow plough which makes open holes: it is a plough formed by a single (right-hand or left-hand) body that enters into and exits from the soil to obtain alternating holes .
  • the known art comprises a reversible plough that makes furrows interrupted by diaphragms obtained with surface soil, operation of which is completely different from that of the plough forming the subject of the present invention.
  • the main purpose of the present invention is to overcome said drawbacks envisaging an equipment designed to carry out an effective tilling of the land against desertification.
  • an equipment of a mounted type comprising, in combination, a subsoiler with two scarifiers associated to a reversible single-furrow plough set at the rear, as well as means for controlling the reciprocating and synchronized action of lifting and penetration into the soil of the subsoiler and of the plough to obtain open holes alternating with water-collecting and retaining pockets in the ground.
  • Figure 1 is a 3D view of a preferred embodiment of the equipment according to the invention.
  • FIG. 2 is a side elevation of the equipment according to the invention of Figure 1;
  • Figure 3 similar to Figure 1, shows the equipment according to the invention from the opposite side; and Figure 4 shows the profile of tilling that is performed with the means for controlling reciprocating lifting/lowering of the bodies carrying out tilling.
  • the mounted and non-towed equipment is specifically designed to make open holes via a reversible, programmable, tool that alternate - in the direction of advance - with water- collecting and retaining pockets in the ground constituted substantially by subsoil areas in which the soil is completely broken up so as that it can be easily impregnated by the water coming from the open holes.
  • the level of the bottom of the water-collecting and retaining pockets in the ground is lower than that of the bottom of the open holes.
  • the soil that has been broken up contained in these pockets is impregnated with water and slows down considerably evaporation thereof, behaving in a way similar to a sponge.
  • said open holes are made by means of a tilling body 1 constituted by a mounted and non-towed reversible single-furrow plough.
  • a first peculiar characteristic of the invention lies in the fact that said reversible tilling body 1 is associated to a subsoiler 10 having a particular shape.
  • Said subsoiler 10 comprises two tines set at a distance from one another of approximately 30 cm and staggered, one further ahead and one further back, so as to maximize the surface of soil broken up without altering the shape of the water-collecting and retaining pocket. Staggering enables a very low power of absorption during tilling.
  • the subsoiler 10 with two tines and the rear tilling body 1 can also work independently on one side and the -other.
  • Two half-wedges A can be applied to the two tines of the front subsoiler 10, which till the land before the rear tilling body 1 generating a pocket of tilled land between one hole and another (to obtain said further accumulation of water) .
  • these half-wedges A by being dragged over the tilled land, generate two channels for connection between the open hole and the buried pocket, said channels advantageously facilitating the passage of the water from the hole to the pocket.
  • the half-wedges A can be positioned at various heights along the tines 10 to optimize their function.
  • a second peculiar characteristic of the invention lies in the fact that purposely designed means are provided for governing lifting/lowering of the tilling body 1 and of the subsoiler 10, which are inserted into/extracted from the soil in a programmable synchronized and reciprocating way to obtain formation of said open holes alternating with and adjacent to said water-collecting and retaining pockets in the ground .
  • the equipment according to the invention comprises, in combination, a reversible plough 1 of a mounted type, plus a subsoiler 10 with two scarifiers, with stiffening jack, as well as safety devices on the jack for oscillation of the subsoiler 10.
  • programmable control means are provided that raise/lower with reciprocating motion the plough 1 and the subsoiler 10 at the desired depth and for the desired time/distance according to the type of soil and the speed/power of the tractor.
  • the tilling body 1 for making the open holes is constituted by a reversible single-furrow plough 1, which is manoeuvred to obtain holes having an adjustable length LI of approximately 5 m and a maximum depth hi of 50 cm, which is also adjustable.
  • the tilling body 1 is fixed to a supporting frame 2 and a jack 3 is provided for oscillation of the tilling body 1 and consequent creation of the open holes ( Figure 4, stretch LI).
  • This jack 3 is actuated automatically by a purposely provided independent hydraulic circuit of the plough as a function of the number of revolutions performed by an appropriate wheel 13 that turns on the land following the effective advance of the tractor over the land so as to make the holes and the pockets in the ground with the desired effective length.
  • a jack 4 is provided actuated by the operator directly from the tractor at each end of pass.
  • the creation of the open holes is obtained by getting the supporting frame 2 to turn, via the jack 3, about the hinge 5.
  • a main frame 6 of the plough is then provided, anchored on one side of which are the supporting frame 2 that carries the tilling body 1 and frames 8, 9 that carry the double subsoiler 10, and which, on the other side, is coupled to the tractor 16 schematically represented by the dashed line in Figure 2.
  • a purposely provided stiffening jack 7 renders the apparatuses according to the invention a single body with the tractor and enables the tilling body 1 to penetrate the soil as soon as it is operated without any repercussion on the degree of freedom of the rear attachment 16c, 16b of the tractor.
  • This stiffening jack 7 is operated by the operator directly from the tractor and has the function of lifting, at the end of each pass, the main frame 6 and of drawing the implements 10, la, lb out of the ground.
  • the subsoiler 10 tills the land by means of purposely designed blades, or tines, or scarifiers anchored to a blade-holder frame 18 equipped with a top connecting rod 8 and a bottom connecting rod 9. Said blades of the subsoiler 10 on the frame 18 are set apart from one another to obtain a furrow having a width of approximately 30 cm and a maximum depth h2 of 85 cm (Figure 4). As has already been mentioned, said depth h2 is adjustable.
  • the aforesaid connecting rods 8, 9 have end hinges 11a, lib, 11c, lid thanks to which they form a parallelogram and enable vertical movement of the blades without altering the tilling angle thereof.
  • a jack 12 enables oscillation (once again beneath the plane of lie) of the blades of the subsoiler 10 for creating the water-collecting and retaining pockets in the ground ( Figure 4, stretch L2).
  • This jack 12 is actuated automatically by the programmable control means of the independent hydraulic circuit of the plough as a function of the rotation of the wheel 13.
  • the aforesaid wheel 13 by rolling over the land during tilling by the plough, actuates a hydraulic distributor via a reducer and a cam.
  • the distributor in turn governs, by means of a series of sequence valves, the jacks 3 and 12 to obtain the tilling profile as in Figure 4.
  • the independent hydraulic circuit that has the function of -actuating the jacks 3 and 12 is equipped with a radiator 14 and a tank 15 with a hydraulic pump (not represented in the drawings) actuated by the power takeoff (PTO) of the tractor.
  • PTO power takeoff
  • 16 is the tractor
  • 16a are the wheels of the tractor
  • 16b are the bottom arms of the lift of the tractor
  • 16c is the tie rod of the third point of the tractor.
  • a jack 4 is provided, which causes the reversible plough to turn about an axis of rotation 17 of the tilling body.
  • the section of the tilling profile obtained with the equipment according to the invention is characterized by the following geometrical quantities, where the length Ll of the open holes and the length L2 corresponding to the pockets in the ground are both programmable and hence modifiable.
