DE102005055408A1 - Loading cart, has front wall horizontally divided in to upper and lower front wall sections, where upper wall section and tactile wall are designed to be lowered, in order to clear front upper opening of front wall for loading cart - Google Patents

Abstract

The cart has a front wall with an upper tactile wall provided in the area of upper ends of the front wall. The front wall is horizontally divided into an upper front wall section (11) and a lower front wall section (10). The section (11) and the tactile wall are designed to be lowered in order to clear a front upper opening (14) of the front wall for loading the cart, in the lowered condition of the section (11) and the tactile wall.

Description

The The invention relates to a loading and transport car with hinged End wall according to the above Features of claim 1.

The execution with a hinged end wall in a loader wagon allowed the filling not only over the loading wagon the loading device provided in the front, lower area of the carriage body, but also for example by means of a separately provided Häckselvorrichtung whose Ejector the shredded material through the front, upper opening in the front wall of the wagon in the carriage body promotes.

In the former type of filling closes the Front wall the cargo space from the front down, the loader by funded Crop is directed into the hold. At the top of the front wall are sensing devices or equipped with sensors tactile wall, which drive a scraper floor to the loading space evenly from fill front to back. At the unloading point, e.g. In a silo, the load (e.g., grass) passes through feeding out with the scraper floor if necessary with a rear-side Abfräsvorrichtung discharged. For this purpose, the during the loading and transport are opened closed and locked rear wall, which preferably happens by means of hydraulic power lift, the supported on both sides in the rear of the side wall parts. Known Executions show for the activity the back wall single or double-acting hydraulic cylinders with which the rear wall opened in printing direction becomes.

such Loading or Silierwagen with their large transport volume can in the second-mentioned Beladeart used as a chaff-transport vehicle become. The filling of the cargo space from above by mostly self-propelled forage harvester not be hindered. At the beginning of a feed stock In addition, the trolley is pulled by the shredder and thus of over the front loaded folded end wall, with the conversion into the respective Beladeart possible should be fast and easy.

So far However, it required considerable renovation work, which is precisely in the hectic Harvesting could not take place and thus the transport capacity of Loader wagons for the chopping insert not used.

Of the Invention is therefore based on the task for loading and transport vehicles to create a hinged end wall with little technical effort which are easily converted to the different types of use can, as well as easy to use. This is the loader and dolly for different Types of charging universally suitable.

These Task is solved from a loading and transport cart with a hinged end wall with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

The formed according to the invention hinged end wall, which together with the tactile wall forward is swung, allows in a simple way, the frontal opening or closing of the Cargo area's agricultural dolly. By the parallelogram-like Storage of the end wall and the associated tactile wall in the form of a Four-joint coupling is achieved that the end wall by a Hydraulic cylinders are easily and quickly transferred to the desired position can.

Further Details and advantages of the invention will become apparent from the following Description of the drawing, which is an embodiment with a hinged Represents front wall. Hereby shows:

1 a side view of a loading wagon with folded end wall;

2 an enlarged side view of the closing end wall; and

3 an enlarged side view of the closed and locked end wall.

The 1 shows a loader wagon 1 with a chassis 2 , a car body 3 and a drawbar 4 , In the front area of the wagon body 3 is below the drawbar 4 a charging device known per se with loading wagons 5 provided that the loader wagons 1 can fill from the bottom front. The carriage construction 3 has a car floor 6 , two side walls 7 , an in front of the direction F front wall 8th and a back wall 9 on. The front end wall 8th is with an upper tactile wall 11 articulated, with the upper tactile wall 11 and the front end wall 8th at the loading wagon loading position ( 3 ) an angle of more than 90 °, eg here in 3 of 130 ° to each other. In the shredder loading position through the folded end wall 8th (when cutting a feed stock) is the tactile wall 11 practically coextensive and largely parallel on the lowered end wall 8th on. In the forage harvester loading from the top side, as is customary after cutting the feed stock, the front wall 8th Similar to the loading wagons operation folded up (see the transfer movement in 2 ) to achieve the maximum transport capacity, but then the rear end of the tactile wall 11 from the linkage 12 solved, leaving the tactile wall 8th again largely parallel to the erected end wall 8th is arranged. The front wall 8th is in the closed state with respect to the front vehicle body 10 tilted slightly backwards. The tactile wall 11 can hang down from the upper axis or as well as the front wall 8th be locked in a slightly reclined position.

By means of one on the front vehicle body 10 and on the front wall 8th on a console hinged working cylinder 13 (see. 2 ), preferably a hydraulically actuated piston-cylinder unit, the end wall can be 8th together with the touch panel hinged thereto 11 and the linkage 12 pivot and tilt diagonally forward and downward, with the rear end of the keypad 12 on the also on both sides articulated linkage 12 is guided. Thus, by the respective end joints of the end wall 8th , the tactile wall 11 and the linkage 12 a four-joint coupling, in particular formed in the manner of a parallelogram guide, so that in the lowered position according to 1 in the upper part of the vehicle body a wide loading opening 14 is created, namely for the shredder operation when cutting a feed stock.

In 2 is in a side view an intermediate position of this four-bar linkage of the end wall 8th , Tactile wall 11 and linkage 12 shown, namely when folding up to position in 3 or when folding down to the position in 1 , Here, the pivoting circles of these components are located around the two lower, most built-up axes. After extending the hydraulic cylinder, the four-bar linkage moves into position 3 how it is used in "ordinary" loading wagon operation. The tactile wall 11 Here is to redirect the towering piles of food from the loader to the load compartment out and also switch the scraper floor on further promotion. The right, topmost end of the tactile wall 11 This is through a slot at the top of the linkage 12 guided vertically. This movement can be used, for example, as a triggering of the scraper floor drive, for example via a proximity sensor, de this stroke of the tactile wall 11 detected.

To the loader wagon also as an agricultural transport vehicle for the harvester harvest with lateral filling (as after the gate with the open filling 14 according to 1 is common in general by the trolley moves parallel to the forage harvester) can be folded as a third position (in addition to the loading wagon position described above) the touch panel in the interior of the loader space, as indicated by the arrow A in 3 is indicated. For this purpose, the joint between the rear end of the tactile wall 11 and upper end of the linkage 12 (in the area of the previously mentioned oblong hole), so that the tactile wall 11 to the upright end wall 8th can be folded down. The tactile wall 11 can also be locked in this position, as well as the linkage 12 , for example on the side wall 7 , Although only one page has been described here, it is preferred for reasons of stability that the same arrangement (eg, a second linkage 12 etc.) also on the other longitudinal side of the loading and transport vehicle 1 is provided. For raising and lowering, however, a hydraulic cylinder is sufficient 13 out to the in 2 Swiveling shown to execute swiftly.
