Abstract

The invention relates to the timber and woodworking industry and relates to vehicles with built-in devices for unloading lightweight goods through the tailgate without tipping. The purpose of the invention is to increase the durability and reliability of the train. The drive consists of a driving pulley 1, mounted on a winch tg ca, a beskno ktno-ISAN- KORON Kona nostv, the rear end of the final drive rope 6, passing under the saddle t of the gauge, the driven shaft with a pulley 2, onboard chain gears 5, floor chain conveyor and tension device. The tensioning device, in turn, consists of a handle with a ratchet 12., which are placed on the side of the body of the manual winch 13 with a drum 14, the tensioning cable 16, the tension roller 11 and the spring compensator 15. The torque from the power transmission box of the tractor is transmitted drive pulley 1, which rotates the driven shaft 2 through a cable transmission, from which the conveyor is driven through the side chain drives 5.

Description

The invention relates to the timber and woodworking industry and relates to vehicles with built-in devices for unloading lightweight goods through the tailgate without tipping.

The aim of the invention is to increase the durability and reliability of the road train,

The drawing shows the drive unloading conveyor, General view.

The drive consists of a driving pulley 1 mounted on a winch and a gacha, a driven shaft with a pulley 2 fixed on a semi-trailer in front of the support beam 3 of the undercarriage, drive shaft 4 of a conveyor mounted in the rear part of the body, two chain gears 5 located along the sides of the semi-trailer. The drive endless rope 6 is stored under the fifth wheel coupling through the guide rollers 7 and 8 mounted on the frame of the wheel lock, bypass rollers 9 mounted on the semi-trailer body, rollers 10 mounted on the supporting beam 3 of the undercarriage and tension. a roller 11 which can move longitudinally in the guides.

A ratchet handle 12 and a pawl are installed at the end of the left side of the semi-trailer. The manual winch 13 with the drum 14 and the spring compensator 15 are installed in the rear part of the body and serve to tension the drive cable 6 through the tension roller 11 by means of a cable 16 fixed at one end to the drum 14, and the other on the spring compensator 15.

The drive works as follows: From the power take-off t, the torque is transmitted to the drive shaft with pulley 1. Through the cable car

The rotation is transmitted to the driven pulley 2 and, through two chain drives, to the drive shaft 3 of the conveyor. The pre-tensioning of the drive rope is carried out by a tensioning device.

When the ratchet handle 12 is rotated through the hand winch 13, a cable 16 is wound on the drum 14, which causes the tension roller 11, which pulls the idle branch of the drive rope, to move in translation. The spring of the compensator 15, compressed, provides a constant tension force of the rope.

Formula of invention

Claims (3)
