Description

Self-loading vehicle

The invention relates to a self-loading vehicle, in which the receiving device receives ground stem and leaf material on the ground and delivers it to a transport device, which sends the harvest good through a substantially upward transport channel into the loading space.

For such loading vehicles, the shipment of goods sent to the loading bay is pushed to the front wall until a flat pile is formed in the fall.

With the scraper bottom, these piles of harvestable goods can be moved back and the harvested goods refilled.

Finally, when loading the raw feed at the end of the loading process, the loading compartment in the front is filled up to the tensioning rope of the upper side of the loading compartment with a compressed loading compartment, while there is a considerable empty space left before the back of the loading compartment which cannot be filled anymore. keeping the compression in the rear loading compartment small and completely inadequate.

When loading with green feed or silage feed, otherwise the overloading of the conveyor and the driveline of the feed must remain restricted, and the scraper bottom triggered beforehand to allow the emerging piles of goods to release the conduit. The loading is therefore not carried out evenly, since the pile of goods is often too little transported forward, but there is still empty space in front of the rear wall of the loading space, or the goods are compressed too much,

22083PP0.IV leads to problems especially when opening, or the loading material can be damaged and crushed by strong compression.

A common drawback in loading is a further drawback, when the overload of the drive line reacts as a fuse with a built-in slip clutch when too much loading material is received and transported.

Therefore, it is essential to eliminate the causes of congestion and re-start, making the loading process as a whole much slower than the capacity of a self-loading vehicle.

To remedy these shortcomings, the load on the drive line of the self-loading vehicle can be controlled by the force receiver and, when the preset load is exceeded by 80 to 90% of maximum torque, the scraper floor can be switched on, and the cutting tool can be pulled out to maintain or increase the load, but when the load is removed again the cutting tool is rotated again and the scraper bottom is stopped.

The loading of the loading area in the area of the transport unit and the front wall of the self-loading vehicle can also be controlled by the force receiver and when the preset load value is exceeded, the scraper floor is switched on, the loading unit is pushed back, the pressure on the front wall is reduced and the scraper floor automatically stops again. .

The sensors are arranged deeper or higher in the loading compartment, depending on the loading space. However, in this type of monitoring, overloads occurring in the cutting tool area cannot be covered, so that damage to the loading material by strong pressure is still possible.

The object of the invention is thus to improve the self-loading vehicle of the aforementioned type, in order to avoid the disadvantages described above, to control the loading apparatus, and to further improve the degree of filling and protection of the feed.

In the case of a self-loading vehicle, this task is accomplished by the features of the characteristic part of claim 1.

22083PP0.IV

By using a central control unit in which sensor signals flow together through a portable device, logical decisions can be made in advance to control the scraper floor, the cutting tool and the transport device in the control unit.

The option to find out the causes of the load increase in the drive line enables the control unit to perform correct countermeasures without delay and to reinforce or end them after the delay has elapsed.

On the other hand, the drive line or at least the transport device can be switched off immediately when the loading compartment is fully loaded or when the clogging cannot be eliminated by idling the scraper floor or twisting the cutting tool.

The speed with which the rudder can react to signals and the ability to take correct actions in a short time increase the safety of damage to the machine and enable very high loading densities at high loading speeds, thus making further use of the loading capacity preparation of a self-loading vehicle.

The invention will now be further illustrated by means of a drawing of an embodiment of the invention, in which the self-loading vehicle with the steering device is shown in the side and cross-sectional view.

In the case of a self-loading vehicle, the stem and leaf support lying on the ground is received by the receiving device 1 and in the transport channel 3 is handed over to the transport device 2, which goods are directed upwards through the transport channel 3, mostly along the front wall 6 of the loading space 4, which is transmitted to the latter. designed from two more side walls 7, as a scraping bottom 5 of the designed bottom 9 and an opening rear wall 8. On the upper side of the loading compartment 4, self-loading vehicles also intended for raw feed and straw are fitted with overlapping ropes extending from the front walls 6 to the rear wall 8 and, in the case of raw feedingstuffs or straw, are used as a retention good.

The conveyor device 2 and the scraper bottom 5 are driven by a drive gear 24, which is designed with a drive shaft joint connection 11 to drive through the drive shaft from the tow vehicle via the drive line 10. _K

22083PP0.IV

The receiver 12 of the force is connected to the drive line 10 with a tensioning device 30 for a flexible sliding drive means 29, whose receiver 12 is connected to the control device 19 via an electrical transmission device 18 and, when the preset load of the drive line 10 is exceeded, signals to the control device 19.

Several pressure receivers 20 are mounted on the front wall 6 as well as on its extension 21, which output signals to the control device 19 when the pressure at the measuring point exceeds a preset value.

The control device 19 switches the scraper bottom drive 14 through the switchgear 13 when one of the pressure receivers 20 transmits a signal on the front wall 6 and switches it off when that signal disappears.

The control device 19 immediately switches on, via the control device 15, a tool 16 for dislodging the cutting tool 17 in order to rotate the blades 27 through part 28 of the depth of the transport channel 3 when the receiver 12 forces the drive line 10 to transmit a pre-set load, and for the cutting tool 17 to be re-swung into the transport channel 3 when this load falls below this preset value.

If the load on the drive line 10 does not fall by twisting the cutting tool 17, then, after a short delay, the control device 19 switches the scraper bottom drive 14 via the switching device until the load on the drive line 10 drops and the receiver 12 no longer transmits a signal; however, if the latter does not occur after a further delay, then the control device 19 stops the drive 22 of the transport device 2 in order to eliminate damage or disturbance.

In the same way, drive 22 is stopped by the control device 19 when, in addition to the pressure receivers 20, the pressure signal encoder 23 of the rear wall 8 transmits a signal due to the preset pressure being exceeded because the loading space is then filled.
