Abstract

PURPOSE:To prevent cargoes or loads from being stacked on the back side of a unloading plate by disconnecting the lower end of the unloading plate from the floor plate of a cargo deck when an unloading member and a sliding member as well are returned from the end position of unloading to the initial posiof unloading. CONSTITUTION:When unloading cargoes thrown from the upper part of a cargo deck, a rear flapping door 14 is opened and a piston rod 12' of a cylinder 12 is extended while a unloading member 5 and a sliding member 3 are moved backward in a sliding manner, forcibly lowering the unloading member 5. When the unloading member 5 is returned from the end position of unloading to the initial position of unloading, the first thing to do is to start the contraction of the cylinder 12. Then, the unloading member 5 and the sliding base 3 as well are moved forward in a sliding manner under the state where the unloading member 5 is kept off from the floor plate of the cargo deck 1.

Description

【発明の詳細な説明】 本発明は、貨物自動車の荷箱に設けた水平排出装置に関

摺動台３が前後方向に摺動自在に装着されている。Hereinafter, the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a cargo box mounted on the frame 2 of a freight vehicle and having an open top surface. A sliding table 3 is mounted so as to be slidable in the front-rear direction.

かにしている。On the other hand, at the rear end of the sliding table 6, a stopper member 10 is formed with receiving parts 10' and 10'' that can come into contact with the frame 8 and a connecting pin 9 provided at the tip of the piston rod of the cylinder, which will be described later. A batt 11 is bonded to the lower surface of the sliding member 3 to ensure smooth sliding on the floor plate 1'.

Piston rod 1 of cylinder 12 whose base end is pivotally supported by k
The tip of the cylinder 2' is connected to the elongated holes 6, 6 drilled in the bracket 7.7 via a connecting pin 9.
By the expansion and contraction action of 2, not only can the sliding table 3 be slid back and forth, but also the discharge member 5 can be swung back and forth.

尚、１６は突起で、排出部材５を排出初期位置へもどし

するものである。Furthermore, 16 is a protrusion that comes into contact with the ejection member 5 and presses the ejection member 5 downward when the ejection member 5 is returned to the initial ejection position, and 14 is a rear sliding door that closes the rear end of the cargo box 1. It opens and closes.

積載物を荷箱１後部より排出できるものである。Next, to explain the operation of the present invention, when discharging the load loaded from the top surface of the cargo box, first the rear fan door 14 is opened.
and then open the piston rod 12' of the cylinder 12.
When extended, while pushing down the ejection member 5,
The connecting pin 9 of the piston rod 12' moves rearward along the elongated hole 6 and comes into contact with the receiving part 10'' of the stopper member 10, and the discharge member 5 starts sliding rearward together with the slide table 3. If the cylinder 12 continues to be extended as described above,
Loaded items can be discharged from the rear of the cargo box 1.

ができる。On the other hand, when returning the ejection member 5 from the ejection end position to the ejection initial position, the cylinder 12 first starts to contract. As a result, the connecting pin 9 of the piston rod 12' moves forward along the long hole 6, and then the connecting pin 9
is held at the front end of the elongated hole 6, and the frame body 8 at the bottom of the discharge plate 4 is held by the stopper member 10. When the cylinder 12 is further retracted, the discharge member 5 can be slid forward together with the slide table 6.

ある。As described above, according to the present invention, when returning the ejection member together with the sliding table from the ejection end position to the ejection initial position, the lower end of the ejection plate provided on the ejection member is separated from the cargo box floorboard.
The loaded items that have entered the back side of the discharge plate remain on the floor plate, thereby preventing the loaded items from accumulating on the back side of the discharge plate, and as a result, cleaning the back side of the discharge plate is not necessary.
