    [0004] Technical sector
    [0005]
    [0006] The present invention is related to the sowing equipment comprising a first machine that is arranged at the rear of the sowing equipment and a second complementary machine that is arranged at the front of the sowing equipment, to jointly deposit a first and second planting material supplied respectfully by both machines. The invention proposes a solution for said planting equipment that avoids turbulence and jams by sending the second planting material from the front to join the first planting material at the rear.
    [0007]
    [0008] State of the art
    [0009]
    [0010] In the field of agricultural work, sowing machines are known that are arranged at the rear of a tractor and that comprise a hopper containing the seeds to be sown, which are dropped in a dosed manner by means of a volumetric distributor, being driven by a flow of air through pipes to the ground.
    [0011]
    [0012] The arrangement of a fertilizer machine at the front of the tractor is also known to carry, also pneumatically, fertilizer grains to be joined with the seeds to be sown, in order to deposit the seeds and fertilizer together in the soil.
    [0013]
    [0014] It happens, however, that when the air flow that leads to the fertilizer from the front to the back, with the flow of air that leads the seeds to the pipes to the ground, collides, turbulence and projections of uncontrolled air, which hinders the sowing process and impairs its regularity, and can also cause traffic jams that impede the continuity of the process.
    [0015]
    [0016] To avoid this problem, solutions have been adopted, such as placing a large cyclone in the planter that expels the air and drops the product of the sowing. This solution is effective, but it is expensive and very cumbersome in suspended sowing equipment, due to the size of the cyclone needed.
    [0017]
    [0018] Another known solution is to place a "Y" in the discharge pipe of the seeds, which allows air to escape, but it turns out that only air must be expelled from the sowing product, so it is an unprofitable solution. Harmful to the crop.
    [0019]
    [0020] It is therefore necessary an alternative solution that allows to solve the previously raised problem.
    [0021]
    [0022] Object of the invention
    [0023]
    [0024] According to the invention, a sowing equipment is proposed that unloads in an improved way a first planting material, such as seeds, from a first machine incorporated in the rear part of the planting equipment and a second planting material, such as fertilizer or seeds, from a second machine incorporated in the front of the planting equipment.
    [0025]
    [0026] The sowing equipment comprises the first machine from which a first material to be sown is pneumatically distributed to an outlet line and the second machine from which a second sowing material is carried through an air flow through a duct to join with the first material at a point where the mixing of both materials is performed. According to the invention, the sowing equipment additionally comprises an air outlet that is arranged in the duct for the escape of the air flow that carries the second material through said duct.
    [0027]
    [0028] With this, the air flow that carries the second material from the front to the rear, escapes to the outside of the duct before encountering the air flow that leads the first material to the outlet conduit, thereby avoiding the collision of both air flows and, consequently, the harmful consequences of said collision, while the second material is effectively carried to the exhaust zone of the air flow, from where it falls by gravity to join the first material in the mixing point
    [0029] This solution is, therefore, effective and practical for the application in the sowing equipment, in which it effectively eliminates the damages of a collision of the air flows that lead both sowing materials to fall together to the ground, totally avoiding the uncontrolled exit of the planting material and without significantly affecting the cost and volume of the planting equipment.
    [0030]
    [0031] Therefore, the invention results in advantageous characteristics for the function to which it is intended, acquiring its own life and preferential character with respect to conventional solutions of the same function.
    [0032]
    [0033] Description of the figures
    [0034]
    [0035] Figure 1 shows in perspective the assembly of a sowing equipment provided with a front fertilizer machine and a rear seeder machine with a conduit that connects them to each other and where the air outlet according to the invention is arranged.
    [0036]
    [0037] Figure 2 is an enlarged perspective of the area of the planting equipment in which the air outlet object of the invention is located.
    [0038]
    [0039] Detailed description of the invention
    [0040]
    [0041] The object of the invention is a planting equipment that is formed by a first machine (1) that is arranged at the rear of the planting equipment and a second machine (2) that is arranged at the front of the planting equipment, both machines (1,2) being connected by means of a duct (3), through which a second planting material is carried from the second machine (2) to join with a first planting material that is dispensed from the first machine (1), so that both materials mix and fall together to the ground.
    [0042]
    [0043] Preferably the first machine is a seeder machine (1) and the second machine is a fertilizer machine (2). Thus, the first planting material is seeds and the second planting material is fertilizer, so that through the duct (3) fertilizer grains are carried from the fertilizer machine (2) to join with some seeds to be sown to be dispensed from the seeder machine (1), so that the seeds to be sown fall together with the fertilizer to the ground.
    [0044] In any case, both machines (1,2) could be seeder machines, so that the first planting material were seeds of a first type and the second planting material were seeds of a second type, thus being able to perform seed mixtures that are deposited jointly on the ground.
    [0045]
    [0046] In these equipments, the seeds to be sown are carried in the seeder machine (1) to a mixing point (5) by means of an air flow, while the fertilizer grains are carried through the duct (3) to that same point mixing (5) by another air flow, avoiding the collision of both air flows, so that the planting process or the planting / fertilization process is not adversely affected.
    [0047]
    [0048] For this, according to the invention, an air outlet (4) is provided in the duct (3), which allows the flow of air that carries the fertilizer grains through the inside of said duct (3) to escape from the fertilizer machine (2) to the seeder machine (1).
    [0049]
    [0050] Thus, the air flow that transports the fertilizer grains inside the duct (3) loses strength and avoids collision with the flow of seed distribution air in the seeder machine (1). This gives a very easy solution to apply in the sowing equipment, without damaging the sowing process of the seeds accompanied by the fertilizer, as the fertilizer grains, once they reach the exhaust zone of the air flow they fall by gravity to the point of mixing (5) with the seeds.
    [0051]
    [0052] The air outlet (4) can be carried out in any way that allows an air passage from the inside of the duct (3) to the outside, a practical embodiment being provided, with a section of the duct (3), formed by a mesh It has some holes with a size smaller than the granulometry of the second planting material, that is, the fertilizer grains or other different seed.
    [0053]
    [0054] Said embodiment is not limiting, being it possible to be any other, for example, through holes or openings made through the wall of the conduit itself (3) or a combined solution of holes and openings, without altering the object of the invention.
