Benefits of technology
[0016]The object of this invention is a self-propelled bagging machine for storing grain in a sleeve comprising a tilting chassis on a single-shaft running gear permanently associated with the wheels, to be towed to its workplace by means of a dragging pole, and fitted with a smaller running gear that only rests on the ground during grain bagging, acting like a steering stabilizer and corrector. An upper bulk grain receiving hopper is mounted on it, which back outlet leads to a grain discharge tunnel and which vertical projection makes it possible for the incoming grain flow to reach an inner slant partition wall arranged downwards to the bottom leading to a tunnel with a back opening connected to the mouth of a foldable sleeve or bag intended to contain the stored grain.
[0017]It is precisely this slant plane connected to the bagging machine that makes it possible for the grain flow falling vertically on it to generate such a force that it is broken down in two directions, driving the grain bagging machine forward—having been checked in practice that this driving force itself activates the forward movement of the machine. Likewise, the slope generated in the bag pushes the bagging machine forward.
[0018]On the other hand, the right working position—as far as the bagging machine leveling is concerned—is given by a front stabilizing running gear height adjustment mechanism. Likewise, once hooked for transportation, the stabilizing gear will be lifted from the ground, and the single shaft on which the equipment will run, released from its attachment to the wheels, will make handling easier.
[0019]The grain discharge hopper is collapsible, which allows safe transportation of the bagging machine from one workplace to another. The hopper is folded and unfolded by means of an engine-driven articulated arm, such as a hydraulic mechanism.
[0028]Attaching the silo bag to the discharge end of the bagging machine may be easily done by a single worker: the above-mentioned folded bag forms a ring that rests on the edge of said semitunnel mouth which is in a horizontal position close to ground level; using the appropriate mechanic tools, such as a manual winch, it is gradually raised to a vertical working position with the bag mounted on it.
Problems solved by technology
The problem with all of them is that it is difficult to graduate their pace, which may result in an inadequate grain compacting due to a fast forward movement of the machine, or in the full sleeve not receiving the amount of grain dropping in through the hopper, thus causing the bagging machine to get saturated due to its slow forward movement.
However, the grain bagging machine described in said patent has a few drawbacks, namely:when used to feed grain into a silo, it moves forward too fast; this movement must be invariably graduated by braking so that bagging complies with the minimum effective storage requirements; andattaching the bag to the support demands more than one worker, considering that the plastic bag weighs about 110 to 130 kg, which makes it impossible for a single man to place it in its working position.
Likewise, calibrating two independent brakes (14) so that they may allow for a smooth forward movement is neither an easy nor a quick task.
On the other hand, the ground on which the machine runs is usually uneven, and such unevenness may alter the force breakdown generated during the grain drop, which, in addition to a different breakdown of the force of gravity acting on the machine's center of gravity, worsen the problems derived from an inadequate calibration of the braking device.

A self-propelled bagging machine stores grain in a sleeve and comprises an upper receiving hopper with an outlet leads to a grain discharge tunnel and is mounted on a chassis equipped with a running gear and dragging pole. The running gear comprises a back single-shaft running gear that is connected to the wheels and a smaller front steering running gear. The grain bagging machine further includes a dual compensated braking device with an adjustable primary hydraulic braking mechanism and an adjustable secondary hydraulic braking mechanism which act simultaneously on the back shaft of the bagging machine. The mechanic articulation is mounted on the chassis and is sensitive to pulling variations and activates an inverted operation hydraulic pump for reception or release of braking fluid to the secondary braking mechanism circuit for braking compensation.
