FR2571585A1 - Liquid dispenser with adjustable flow for treating seeds on the farm - Google Patents

Abstract

The invention relates to a dispenser container placed in a raised-up position on a ladder or step-ladder, making it possible regularly to introduce a liquid product into an auger conveyor for grain, for the treatment of seeds on the farm. It consists of a container 1 containing the treatment liquid, which flows via the siphon 4, itself held by the float 5. This siphon slides freely downwards, guided by the tubular device 6 in step with the flow of the liquid, which is regulated by the quarter-turn valve with adjustable stop 7, 8 and 9. The product then flows through a transparent flexible plastic tube 10 and joins the operating auger conveyor 11.

Description

The present invention relates to a metering distributor for treating seeds on the farm by introducing a liquid product into a grain auger to ensure mixing with cereals,
Indeed, these treatments were most often carried out with powder or various makeshift means which had the disadvantage of inconvenience the users because of the harmful dust breathed during these operations.

 The appearance of liquid products in seed organisms has made the work of users and farmers who preferred to buy all-treated seeds rather than breathing the powder easier. These seeds purchased being more expensive than those produced on the farm, a first generation of distributors of liquid products appeared on the market, they included 2 trays, including I at constant level.

 The object of the present invention is to present a simplified metering distributor, more economical to purchase while remaining practical and precise. The main assembly includes a single strong plastic container preferably, provided with a device provided with a siphon and a float, and at the outlet of a quarter turn valve.

When the siphon is primed, the combination of these three elements allows, by opening the tap (which is provided with an adjustable stop), to obtain a constant flow regardless of the height of the liquid in the tank, since the siphon retained by the float slides progressively outside the tank following the upper level of the liquid. The pressure therefore remains constant
A flexible and transparent plastic pipe preferably connects the outlet valve of the siphon and the tube which allows the liquid to be introduced into the screw which ensures by its rapid rotation a perfect mixture of cereal product.

 The float trap assembly must, of course, be raised above the level of entry of the liquid into the screw. It can be placed on a ladder or on a stepladder by a support provided for this purpose.

 The siphon can be primed by suction, but also by external pressure by injecting with a special bulb water or liquid through the outlet tap.

 This device can also be used to introduce water (with or without a fatty additive) into a grain auger in order to avoid harmful dust during the treatment of seeds by means of a powder. In this case, he plays the role of humorist.

The invention will be better understood by referring to the accompanying drawings which represent an exemplary embodiment:
Figure 1 shows a side view of the device according to the invention.

 Figure 2, a plan view showing mainly the reelage device.

 Figures 3 and 4, adaptation on ladder and stepladder.

 Referring to Figure 1, it will be noted that the tank (1) is positioned on a scale (2) via the support (3). The siphon (4) retained at the upper level of the liquid by the float (5) slides freely from top to bottom in the tubular device (6) itself fixed at the upper end of the tank (i), this progressively as the 'flow of liquid, the flow rate of which is regulated by the quarter-turn valve (7). The lever operated by the operator comes to bear on the adjustable stop (8) which slides in the circular light device (9). The liquid flows through the transparent flexible plastic pipe (preferably) (10), it will join the grain screw (11) via a small penetration tube forming part of the assembly (12) blocked by tightening on the grain screw, the latter being drilled accordingly.

 Figure 2 shows a plan view of the main device. We will especially notice the flow adjustment part with the circular light.

 Figure 3 shows in perspective the adaptation on a scale.

 FIG. 4 represents an exemplary embodiment on a stepladder.

 These adaptations are not limiting.

Claims (5)

1) Device for ensuring a regular, adjustable flow of liquid to be introduced into a grain auger for the treatment of seeds on the farm.  It is characterized in that it comprises a strong plastic container mounted on a ladder or stepladder, this container (1) containing the liquid which flows through the siphon (4) 2) Device according to claim I characterized in that a float (5) retains the siphon at the upper level of the liquid, which siphon slides in a tubular device (6). 3) Device according to claims 1 and 2 characterized in that the liquid then passes through a quarter turn valve with adjustable stop, which thus allows to dose or stop ztéclow; This quarter-turn valve float siphon combination provides precise and regular flow regardless of the height of the liquid in the tank. 4) Device according to claims 1, 2, and 3 according to which the siphon can be primed with water or liquid by injection at the tap (after rapid operation of the latter) 5) Device according to claim 1, 2 and 3 according to which the liquid then flows through a transparent flexible plastic tube, and will join the grain screw in operation drilled for the occasion.
