Abstract

PURPOSE:To prevent floating-up of a discharge plate installed in slidable ways into a packing case and efficiently utilize the power of the driving means of the discharge plate by freely changing the installation position of a pivotal supporting shaft for connecting the discharge plate and the driving means for the discharge plate. CONSTITUTION:A discharge plate 5 is arranged in slidable ways into a packing case 2, and one edge of a telescopic cylinder 8 the other edge of which is pivotally installed onto the front edge of the packing case 2 is connected to the discharge plate 5. In this connection structure, a pivotal supporting shaft 13 fixed onto the cylinder 8 is engaged in slidable ways into a backwardly highly positioned inclined long hole 12 formed onto a bracket 11 fixed onto the back surface of the discharge plate 5. The pivotal supporting shaft 13 is shifted in the long hole 12, linked with the slide of a stopper member 14, by the stopper member 14 which is slided along the above-described long hole 12 by the operation of an operating handle 15. Therefore, the installation position of the pivotal supporting shaft 13 can be changed freely in accordance with the kind of loaded articles.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo discharge device for a truck.

Conventionally, a discharge plate is provided in the front and back of a cargo box mounted on a vehicle frame in an active position, and a driving means is provided between the front end of the cargo box and the rear surface of the discharge plate, and the drive means is driven to discharge the cargo. A loaded discharge device for a freight vehicle is already known in which a plate is slid backward to discharge the loaded load in a cargo box, but the mounting position 1u of each pivot shaft in the activation means has been changed. (i!i1 is added, so if you transfer the load from fresh concrete to sawdust and discharge this sawdust, there is a risk that the lower end of the discharge plate will lift up, and additional It had to be powered.

The invention has been made in view of the above points, and the present invention will be described in detail below with reference to the drawings.A cargo box 2 with an open top and rear surface is mounted on a vehicle frame 1 of a freight vehicle. At the rear 1111, a rear door 6 whose rear surface can be closed is pivotally supported 4 so as to be openable and closable.

On the other hand, a discharge plate 5 that extends to the full extent of the discharge plate 5 is housed in the cargo box 2, and a sliding member 7,... The discharge plate 5 moves on the floor surface of the cargo box 2 via this sliding groove 7.

Further, a telescopic cylinder 8 as a driving means is disposed between the front end of the cargo box 2 and the discharge plate 5, and by telescopically operating the telescopic cylinder 8, the discharge plate 5 is moved forward and backward of the cargo box 2. It can be moved or stirred.

By the way, the tip of the telescopic cylinder 8 is pivoted 10 to a bracket 9 erected at the front end of the cargo box 2.
The pivot shaft 16 at the end of the bracket 16 is engaged with an elongated hole 72 that is inclined toward the rear of the bracket 11 fixed to the back surface of the discharge plate 5 . A stopper member 14 with which the pivot shaft 16 can be superimposed is placed in the elongated hole 12.
The stopper member 14 is slid into the long hole 12 by turning the operation handle 15 as appropriate.
can be slid along.

Next, the operation of the present invention will be explained. When the cargo box 2 is fully loaded, the discharge plate 5 is located at the rjj1 portion of the cargo box 2 as shown by the dashed line in FIG.

Now, when discharging a load of ready-mixed concrete by υF, as shown in FIG.
After adjusting the line of action of the telescopic cylinder 80 slightly downward, if the Japanese button door 6 is opened, and if the telescopic cylinder 8 is extended and shifted, the lower end of the discharge plate 5 will not be lifted up, and the discharge plate 5 will be placed in the cargo box. 2, and ready-mixed concrete can be discharged from the rear of the packing box 2.

Next, when discharging a bulky load such as sawdust and a high ff1i center position, rotate the Torasaku handle 15 in the opposite direction to the above and move the stopper part (j14 upward along the elongated hole 12). If the telescopic cylinder 8 is extended as described in ゎiJ, then the 11th branch of the telescopic cylinder 8 as shown in Fig. , then the movement of ``F1-Dezuki5'' is li! J starts. Therefore, the lower end of the discharge plate 5 does not lift up, and the discharge plate 5 moves rearward while the vertical component of the thrust of the telescopic cylinder 8 is reduced, making it possible to discharge the sawdust from the rear surface of the cargo box 2. can.

On the other hand, if the telescopic cylinder 8 is retracted again, the pivot shaft 16 will be in proportion to the lower end of the elongated hole 12, and then the discharge plate 5 will move forward, and the loading of the two objects will become 'uJrt'.
= becomes.

In addition, in the embodiment of "Misfire 19", the telescopic cylinder 8
As another example, the pivot shaft in the telescopic cylinder 8' Jjla iyE]
The mounting position of O may be changed, and as another embodiment, both phase support shafts 10 at the distal end and the proximal end may be changed.
．． The mounting position of 13 may be changed.

As described above, according to the present invention, the mounting position of the pivot shaft in the drive means can be freely changed according to the type of the loaded object, so that lifting of the discharge plate can be prevented, and the vertical direction relative to the power of the drive means can be changed. It is also μJ ability to reduce the component force,
As a result, shadowing due to frictional resistance is suppressed, and the tCJ of the drive means is reduced.
Power can be used efficiently.
