FR2553191A1 - Device, mounted on a lorry for the transport of bulk goods, enabling the exact weight of the product delivered to the client to be measured on the lorry - Google Patents

Abstract

Device, mounted on a lorry for the transport of bulk goods, enabling the exact weight of the product delivered to the client to be measured on the lorry. This device weighs, before it is unloaded, the product unloaded by its mechanical device, specifically by Archimedean screw 4, 5, 7. This device is built into the body or compartment 11, here termed the "weighing hopper" 2. This bulk product 17 may also be transferred by elevating tube 8 either into a silo or into a storage bay. This device is useful for all transporters of bulk materials.

Description

Device mounted on a goods transport truck
bulk to control the exact weight on dru pro truck
delivery to the customer.

This device allows weighing before its discharge, the pro
duit discharged by its mechanical device, that is to say by Archxmede screw.

This invention consists in integrating into the body a
compartment (II) which will be called "Weigher hopper.

The vehicle consists of a helical screw-central
collector (9) rotating in a trough bringing the product
than the transverse helical screw (4) directing the arrival
of the product, towards the vertical screw (5), then in (7) or the product
(I7) will fall at (15), into the weighing funnel (2), place in the compartment (II). Once the weighing has been saved; seen from
outside, the hatch (3) will be opened so as to leave
drop the weighing in the chute (9) or it will be driven
this time by the same screw (4) turning in the opposite direction
in the vertical (8) and horizontal (14) screw or it will fall
in the horn silo stored in the attic, for example.

For unloading one of the example compartments; (I2)
and (I3), we will proceed as follows;
I Operation, the hatches of the weighing hopper are closed,
we open the hatch of the compartment concerned (not visible here
the product flows through the inclined wall of the compartment through
gravity, in the trough of the longitudinal feed screw (9) which it drives in the feed screw (4), which in turn drives it in the vertical screw (5) and in the filled screw
sage (7) to finish in the weighing hopper (2). Once
the desired quantity obtained, we close the compartment hatch
while leaving the screws to operate, the circuit is then in
emptying.

2 nd Operation; weighing completed, automatic device
will control the hatches (3) for opening the hopper (2) as well
that the starting of the engines driving the v-is for the
unloading. By reversing the direction of rotation of the feed screw (4), the product then flows to the elevator (8) which can be articulated to it in (IO) as well as the distribution screw
(I4) which drops the product in the silo or in the place
of storage.

The purpose of this patent is to practice the circuit for unloading a bulk product, in order to control the quantity and
the exact weight via a weighing hopper (2) placed in
the truck equipped with a mechanical device - operating by Archimedean screw, which avoids additional displacements of the vehicle to carry out weighing at the Public scale at each
customer and collect invoice and taxes at the same time.

 The invention will be better understood by referring to the description and the drawings shown and described given by way of example; schematic, non-limiting indicative and are subject to numerous variants of embodiments and applications, as a new industrial product.

 FIG - I - represents seen from the rear of the truck and in the compartment (II) in which is located the weighing hopper (2) whose hatches (3) are closed so as to allow filling and dosing of the material to evaluate. In (9) the longitudinal central screw which pours the product into the feed screw (4) which has two directions of rotation, one direction to lead the product into the weighing hopper passing by the vertical screw (5) and the filling screw (7). The product then falls into the weighing hopper. The other direction of rotation is used to feed the lifting screw (8) which feeds, the distribution screw (I4).

FIG- 2 - represents the detail of the transverse screw (4), in a state to transmit the master received from the gutter (9) in the lifting screw (8) where it will be evacuated to be stored
In (IO) I the articulation or pivoting of the tubes comprising the helical screws. The dotted lines of this screw (5- show the direction for the rise towards the weighing. The propellers indicate the entrainment of the material towards the rise in (8).

FIG- 3 - represents in perspective in the longitudinal direction / a truck fitted with compartments (II) (I2) (I3) for example, showing the longitudinal drive screw in the gutter (9) driving the bulk material towards the screw (4) or it will be distributed on the one hand; for weighing in (I5) in the compartment (II) where the hopper (2) is located. On the other hand, for the rise in (8) in the vertical and horizontal elevating screw (I4) where it will be poured for storage in (I6). In (I8) the screw drive motor, simulated,
FIG- 4 - shows the diagram of the distribution circuit according to
the use, towards the weighing, represents in dotted lines or in the direction of storage. The invention may vary in shape, material, dimensions of mechanical principle, but will remain within the framework of
the new idea which is the subject of this patent.

Claims (1)

 10 Device mounted on a freight vehicle  in bulk, to control the exact weight ~ on truck  before delivering it to the customer, characterized by the fact that  bulk material, grains or flour for example, will be  weighed automatically before leaving the trans vehicle  carrier, by a weighing hopper installed in a place  cement or compartment specially fitted out for this purpose.  20- Device according to claim - I - characterized in  what the bulk material deposited according to the quality in  separate compartments (I2) (I3), will be evacuated on a  longitudinal helical screw (9) which will bring it towards the  transverse screw (4) or according to the case, it will be distributed  to weighing or storage.  30- Device according to claim - I - characterized in that  that the gutter (9) in the center of the transverse screw (4),  will allow to the right, here represented to direct the  material to the weighing where it will then be after opening  hatches (3) dropped by gravity onto the central screw  distribution (9) to be directed towards the screw  vation (8) and (I4) where it will be put in Silo or in storage  4 - Device according to claim -I- characterized in that  that the transverse screw (4) thanks to a hatch placed at  lair on top, allows loose material to be deposited there  which we want to fill the truck with.
