Sweden-Sweden (SE) 7608 ^ 96-1 (71) (72) Dan Richardsson, Södra Kyrkogatan 5, 531 00 Lidköping,

The present invention relates to an apparatus for emptying, for example, a tank, container or the like placed in a lorry, which tank comprises a tank, container or the like. the two opposite side walls suspended from the upper hinges pivotally around the upper hinges, a movable base plate pivotally connected to the lower edge of the first side wall and a fixed base plate, the device comprising means for pivoting the side walls around the upper hinges and

Fluffy materials, such as wood chips, sawdust, bark and the like placed in the truck's tank, tend to condense during transport and are difficult to empty in the usual way, i.e. by tilting backwards or sideways. The condensed material remains in the tank, although this is tilted very much.

Modifications have been proposed to the container which is emptied by simultaneously turning both its side walls and the base plate in the same direction. In this case, the base plate is pivotally connected to the second side wall, so that it will be in line with said side wall in an inverted position, whereby the substance slides away easily. The turning can be achieved by means of a hydraulic device or a wire device.

A disadvantage of the known devices is that the turning device is made in such a way that considerable traction forces are generated on the turned side wall. Therefore, the upper hinge of the side wall must be made very solid in order to be able to receive high stresses on it.

The object of the present invention is to eliminate said drawback and to make the turning device so that the upper part of the container is not subjected to such high stresses. In this case, the container can be made much simpler and cheaper. Instead, the tank's relatively strong base structure receives stresses.

According to the invention, this object is solved in that said member is formed by at least one lever or the like comprising two mutually movable parts, one of which is pivotally attached to one side edge of the bottom of the container and the other part pivotally attached to one side wall.

The invention will be explained in more detail below with reference to an application example shown in the drawings.

Fig. 1 shows a perspective view of a truck with the tank in the emptying position, Figs. 2-4 show sections of the tank in its various emptying stages, Fig. 5 and Figure 7 shows another structure of the lever.

In the drawings, reference numeral 10 denotes a truck tank comprising a front and rear baffle 11, respectively. 12, first and second side walls 13, resp. 14, a movable base plate 15 extending approximately half the width of the vehicle and a fixed base plate 16. The side walls 13 and 14 are suspended at their upper edges so as to pivot about the upper hinges 17 and 18 and are connected to each other by one or more parallel-arranged bars 19. lower than its attachment point to the second sidewall 14, and when the container 10 is turned inward when the container 10 is emptied, the second sidewall 14 pivots outward, the sidewalls being oriented in different directions, as most clearly shown in Figure 4. This further facilitates emptying.

The movable base plate 15 is pivotally connected to the first side wall 13 via a lower hinge 20.

The turning of the side walls is effected by means of one or more hydraulic levers arranged transversely to the container 10. The piston rod 21 of the lever lever is pivotally connected at its free end to a fixed base structure 24, in the middle of the lower edge® of the first side wall 13. The piston rod end end 21 of the hydraulic cylinder 22 is pivotally mounted on the inner side of the lower edge of the first side wall 13, the piston rod 21 being guided through a hole 23 in the side wall 13. When the piston rod 21 is fully retracted inside the cylinder 22, the attachment of the piston rod to the base structure 24 will be in the hole 23 · The attachment of the lever is best illustrated in Figure 5 ·

When the side walls 13 and 14 are fully folded in (Fig. 2), the cylinder 22 rests against the base 10. When the piston rod 21 is pushed out, the side walls 13 and 14 simultaneously pivot their respective hinges 17, respectively. 18 in the figures to the left, i.e. the first side wall 13 pivots towards the inside of the container 10, while the second side wall 14 pivots outwards from the container 10. In this case, the movable base plate 15 moves along the fixed base plate 16 and simultaneously pivots around the hinge 20 and is aligned with the first side wall 13 in the position shown in Fig. 4. The movable base plate 15 also acts as a stiffener for the side wall 13 during emptying, so that the structure can be made light but still strong.

By fitting the force lever as described, whereby the angle between it and the side wall 13 increases throughout the unfolding, it is obtained that when the fluffy material 25 is packaged so as to act as a unitary piece shown in Fig. 3 by dotted lines, the force lever does not protrude. , therefore, none of the mentioned pressure loads the lever. As a result, the traction forces on the inverted side wall 13 are also reduced to a minimum, and the structure of the container therefore does not have to be made very solid, heavy and expensive.

In order to prevent as much as possible from retaining the shape of the compressed body, it is important that the outer side wall 14 deviates from the direction of the inner side wall 13. This ensures that the outer side of the body, on the side wall 14 side, loses support and can break due to its own weight and / or the reciprocating nature of the side walls 13, 14.

The invention is not funded by the embodiment shown, but may vary within the scope of the claims. Thus, the hydraulic lever can also be formed by a manual or motor-driven mechanical power machine in which the piston 21 has been replaced by a rotating screw and a cylinder by a sleeve nut. Further, it is possible to match people lever the container end walls of the interior of the sihasta also outside them or in suohuskotelon, the side wall 13 of the lower corner portions ohhaustapit projecting through the end walls, respectively, suohuskotelossa openings.

According to the embodiment of Figure 6, the piston rod 21 is loosely arranged so that the lever can be turned around the bearing pin 26. To perform this movement, a groove is fitted in the hinge 20 and in the base plate. In addition, the support member 28 acts as an Olak of the piston rod. When the lever is in a bullet-straight position, the entire bottom surface of the tank is free for use for transporting goods.

According to the embodiment of Figure 7, the rods 19 are arranged as a lever, which can be individually made for hydraulic or pneumatic use. The side wall 14 can thus be opened and closed regardless of whether the method is generally used. In this case, the loading space is easily accessed from another long side.
