CN2105477U - Conveyer with extension belt - Google Patents

Abstract

The utility model provides a conveyer with extension belt, which is characterized in that the conveyer with extension belt comprises a movable frame which can slid from left to right in a host. The goal of extension can be achieved by the motion of the movable frame in a host frame from left to right when a motor is started up.

Description

Conveyer with extension belt

The utility model relates to a kind of telescopic belt conveyer, and the cargo handing that is specially adapted to freight container is carried.

Band conveyor generally all is a fixed length, but under some occasion, the distance that often needs to carry constantly changes.

The purpose of the utility model machine will provide a kind of improved band conveyor exactly, not only can play the effect of general band conveyor with it, and can also change the length of its conveying as required.

The utility model machine is achieved in that in the conveyer the inside a telescoping mechanism; Linked to each other with a sprocket wheel by motor via reducer, sprocket wheel is meshed with chain again.

When flexible motor starts, just be with tressel to move forward and backward, its right-hand member has a link carrying roller group, guarantees that by drawing back and shrinking chain idlers pitch can not exceed requirement.

The utility model machine is easy to realize as long as increase by a cover retractor device at former conveyer.Because conveyor lengths can change, carry needs so can satisfy better.

The structure of utility model machine is drawn by following examples and accompanying drawing thereof:

Fig. 1 is that Fig. 2 is the enlarged drawing at M place according to the structure diagram of the band conveyor of the utility model machine proposition.

Describe the details and the service condition of the concrete device that the utility model machine proposes in detail below in conjunction with Fig. 1 and Fig. 2.

This device has 8 operations of motorized pulleys 1 drive load-transfer device to come convey materials, the whole load of mainframe 2 burdens; Tressel 3 is contained in the slideway of mainframe 2, can horizontally slip under the drive of motor 13, to reach flexible purpose; Motor 13 links with reductor 6, and reductor 6 drives sprocket wheel 9 again and rotates, and sprocket wheel 9 is meshed with chain 10 on being fixed on mainframe; Changed course cylinder 4 is used for changing the belt direction; Changed course cylinder 14 is contained on the tressel 3, so that keep the elasticity of belt when tressel 3 sway; Parallel roll group 5 and link carrying roller group 11 are used for holding in the palm flat belt, and parallel roll group 5 directly is fixed on the tressel, can not slide, and link carrying roller group 11 is contained in the bilge logs of mainframe 2, can horizontally slip; Connection seat 7, one ends are fixed on the tressel 3, and an end is fixed on the link carrying roller 11, and when tressel 3 sway, connection seat 7 also forces link carrying roller sway; Chain 12 two ends respectively are connected on the link carrying roller 11.

Claims (3)

1, the changeable band conveyor of fed distance, this device has a motor 13, drive a tressel 3 can be in the slideway of mainframe 2 sway, it is characterized in that:

A: described device has sprocket wheel 9 to be contained on the tressel, and motor 3 is meshed with chain 10 on being contained in mainframe through reductor 6 transferring power;

B: have a changed course cylinder 14 to be contained on the tressel 3;

2, conveyer according to claim 1 is characterized in that having one group of link carrying roller group 11 to be contained in the slideway of mainframe 2.

3,, it is characterized in that having chain 12 connecting two link carrying rollers according to claim 1,2 described conveyers.
