Description

Auxiliary hopper for seeders and fertilizers

This utility model describes a auxiliary hopper for seeders and fertilizers that is suitable for placement on the front of the tractor that moves said seeder and / or fertilizer and that enables an additional load of seeds or fertilizer

Prior art

The seeders and / or fertilizers are agricultural tools that are moved by a tractor and that generally include a rudder to hook the motor element, a chassis and a hopper designed to contain the seed that is dosed during sowing to the sowing elements. properly
sayings

The hopper of these tools, of course, it is of limited capacity, since normally the weight of the hopper and its content affects the depth of planting, as well as in the whole mass center itself tractor-seeder.

These limitations in planting load imply that, in the vast majority of cases, the farmer you need to make multiple trips to reload the hopper in the warehouse of grain or fertilizer, or take a second tractor with trailer and auxiliary loading of grain or fertilizer and means for recharging of the seeder / fertilizer hopper.

Explanation of the invention.

The technical problem that the present solves utility model is to increase the load of grain or fertilizer during the sowing or fertilization operation itself.

To solve this technical problem, an auxiliary hopper for seeders and fertilizers is described in this utility model, which, being intended for use on the front of the tractor, also includes means for joining the hopper to the tractor, means for transfer the grain of said auxiliary hopper to the seeder or fertilizer hopper
Dora

Said means of transfer include, in turn, at least one connecting duct between both hoppers, a turbine of air connected to the auxiliary hopper outlet and an element of closing and passing of the grain or fertilizer, which is automatically operable or at the farmer's will from the tractor itself.

Thus, when the hopper load of the planter decrease, the passage of grain from the hopper is enabled auxiliary, by Venturi effect of the turbine air towards the hopper of the seeder / fertilizer, obtaining two clear advantages over the seeders known in the current state of the art:

i.

Be considerably increases the load of grain or fertilizer that a Farmer can employ without returning to the warehouse or without employing a trailer or auxiliary tractor.

ii.

Be balances the weight of the tractor-seeder assembly, making use of counterweights on the tractor unnecessary, such as It is currently happening.

Throughout the description and the claims the word "comprises" and its variants not they intend to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and features of the invention will be partly detached of the description and in part of the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to be limiting of the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.

Brief description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a practical embodiment thereof, the following figures are attached as an integral part of the description, where with character illustrative and not limiting the following has been represented
tea:

Fig. 1 shows a view of the hopper auxiliary object of this utility model, where it is observed the part of union with the front of the tractor.

Fig. 2 shows a second view of the hopper auxiliary object of this utility model, where it is observed the front of it.

Detailed presentation of an embodiment

As can be seen in the figures attached, the hopper (1) is an essentially quadrangular hopper, of typical trapezoidal or funnel configuration. Said hopper (1) rests on a chassis comprising four supports or legs (21, 22) of such that on its front legs (21) the headlights (23) of the hopper, since it covers the tractor itself, since the auxiliary hopper is designed for use in tractors and, therefore, homologable for driving on roads.

On the other hand, between the hind legs (22) the unions or hooks (3, 4) are placed on the tractor. Sayings hooks (3, 4) in a particular embodiment of the present invention are two:

to)

a first hitch (4) for the three-point front hooks; Y

b)

a second hitch (3) for the hooks of the counterweights of a farm tractor;

By the advantageous inclusion of both types of hooks (3, 4) it is obvious that the auxiliary hopper recommended in this model it can be used on any tractor agricultural and with any type of coupling of the usual in the market.

The hopper (1) in its lower part, comprises the means of transferring grain to the main hopper of the Seeder or fertilizer. Said means of transfer include, essentially, a first communication conduit (5) between the hopper auxiliary (1) and the main hopper, where said duct (5), to its once, it is connected to a turbine (6), jointly and severally connected to the chassis (2) of the hopper (1), and which is configured to push the grain or fertilizer that falls by gravity of the auxiliary hopper (1) towards the main hopper by Venturi effect.

Finally the means of transfer include opening and closing means of the lower opening of the hopper (1), wherein said means essentially comprise a chopping board or hydraulic seal (7), although another type of drive is possible with the right connections, and that is manually operable, from the tractor's cab, at the will of the farmer, or automatically, when the grain in the hopper main reaches a certain threshold level, below which the closure (7) is opened and the turbine (6) is activated, passing the grain from the auxiliary hopper (1) to the main hopper of the planter / fertilizer

Finally, it should be noted that the turbine (6) is driven by a hydraulic motor or by means of a cardan transmission to the power take-off, although other forms of drive are not discarded.

Claims (4)

1. Auxiliary hopper (1) for seeders and fertilizers that, being intended for use in the front of the agricultural tractor, also includes first means for joining the hopper to the tractor (3, 4) and a few second means for transferring the grain of said auxiliary hopper to the seeder or fertilizer hopper and characterized in that the grain transfer means essentially comprise a first communication conduit (5) between the auxiliary hopper (1) and the main hopper, wherein said duct (5), in turn, is connected to a turbine (6) that is housed under the hopper (1) and with the opening and closing means of the hopper (1), these elements being located in the lower opening of the own hopper (1); Y where the opening and closing means of the Bottom of the hopper (1) essentially comprise a chopping board or hydraulic seal (7) that enables grain gravity or fertilizer contained in the auxiliary hopper (1), in turn activating the turbine (6) for grain transfer by Venturi effect. 2. Auxiliary hopper (1) according to claim 1 characterized in that the opening of the closure (7) is manual at the will of the farmer from the tractor itself. 3. Auxiliary hopper (1) according to claim 1, characterized in that the opening of the closure (7) is automatic, when the grain level of the main hopper has fallen below a certain threshold value. 4. Auxiliary hopper (1) according to the preceding claims, characterized in that the means for joining the hopper to the tractor comprise at least one selected from: (a) a first hitch (4) for the front hooks of three points of an agricultural tractor; (b) a second hitch (3) for the weights of the weights of an agricultural tractor; and (c) a combination of the above.
