Description

A kind of connection structure and belt elevator of belt and hopper

Technical field

The utility model belongs to engineering machinery field, and the connection structure and belt bucket type of especially a kind of belt and hopper mention The machine of liter.

Background technique

Existing belt elevator is a kind of very widely used mechanical conveying equipment, and working principle is usually Rubber leash is centered around between driving drum and following bend pulley above, and hopper is uniformly fixed on leads at a certain distance On leader tape, casing seals hopper and leash.Material is led into moving hopper or hopper material by bottom from bottom Storage in scoop up, as conveyer belt is promoted to top, around being downwardly turned over after the driving drum of top, in centrifugal force, gravity Under effect, material is drawn off from discharge port, is sent into next procedure.

The mechanical strength of rubber leash itself is lower, and the hopper being uniformly fixed thereon will be because of connection loosely It leans on, is split away off using the even entire hopper of loosening, abjection that just will appear hopper shortly after, it has to frequent shutdown maintenance. The popularization and use of belt elevator are directly influenced thus.

Defect existing for belt elevator is as follows: existing connection fastening bolt device existing defects are directly made At hopper in the case where not long between when in use loosening and fall off, it is final to generate crack while also result in rubber leash Shorten rubber traction tape lifetime；Maintenance, maintenance workload are big, and operation rate is not high；Even if having replaced hopper connection in time Fastening bolt device, the time is not long and can repeat the loosening of hopper and fall off.

Utility model content

The goal of the invention of the utility model is to provide the connection structure and belt elevator of a kind of belt and hopper, uses In solve the problems, such as belt elevator hopper be not connected firmly by.

In order to achieve the above objectives, technical solution used by the utility model first aspect is:

The connection structure of belt and hopper in a kind of belt elevator, including connection component, several described connections One hopper is fixed on the belt of the belt elevator by component, and each connection component includes the first gasket, screw With nut group；First gasket includes conical shell, and the conical shell both ends are equipped with and communicate and nozzle of different sizes, institute The periphery wall for stating the big nozzle of conical shell is equipped with the annular baffle being connected with it；The belt is equipped with and the conically shaped The through-hole that external wall matches, the conical shell are arranged in the through-hole of the belt, and the side of the annular baffle abuts In the right side of the belt；The side of the hopper abuts the left side with the belt, and the head of the screw is and the cone The pyramidal structure that shape inner barrel matches, the screw pass through the cylinder and pass through the hopper side wall, the screw Left end passes through the fixed hopper of nut group.

Further, the nut group includes two nuts.

Further, the second gasket is additionally provided between the nut group and the hopper.

Further, second gasket is flat shim.

Further, the nut group and the screw welding.

Further, the screw is hexagon socket countersunk flat cap head screw.

Further, the material of first gasket is mild steel.

According to the second aspect of the utility model, a kind of belt elevator is provided, the company with belt and hopper The connection structure of binding structure, the belt and hopper is the belt according to any one of described first aspect and hopper Connection structure.

Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:

1. first gasket of the utility model includes conical shell and the annular baffle that is connected, be conducive to increase first The contact area of gasket and belt, the first gasket can either compress rubber traction belts during installation, while protect rubber again Traction belts.Ensure that hopper is not loosened, do not loosened belt elevator in use, at the same belt realize it is lossless Wound operation, greatly improves the service life of belt elevator.

2. nut is also connect with screw by welding, so that hopper be made to exist since nut group includes two nuts It works in operational process more stable, stronger.

3. to be conducive to protect hopper, while also being protected due to being additionally provided with flat shim between nut group and hopper It demonstrate,proves stablizing in hopper operational process and is connected firmly.

4. being formed since the material of the first gasket is mild steel convenient for punch process, while having good toughness will not Fracture, to improve the service life of the utility model.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model connection structure

Main element symbol description is as follows in figure:

In attached drawing, 1- hopper, 2- nut group, the second gasket of 3-, 4- belt, the first gasket of 5-, 6- screw.

Specific embodiment

The specific implementation of utility model is further illustrated below in conjunction with attached drawing.

As shown in Figure 1, in a kind of belt elevator belt 4 and hopper 1 connection structure, including connection component, if One hopper 1 of elevator is fixed on the belt 4 of elevator by a dry connection component.According to the size of hopper 1 in elevator Size can be selected appropriate number of connection component and hopper 1 be fixed.

Each connection component includes the first gasket 5, screw 6 and nut group 2；First gasket 5 includes conical shell, conically shaped Body both ends are equipped with and communicate and nozzle of different sizes, and the periphery wall of the big nozzle of conical shell is equipped with the annular baffle being connected； Belt 4 is equipped with the through-hole to match with conical shell outer wall, and conical shell is arranged in the through-hole of belt 4, and its outer wall supports It is connected to the through-hole wall of belt 4, the side of annular baffle is connected to the right side of belt 4；The side of hopper 1 abuts and belt 4 Left side, the head of screw 6 are to pass through cylinder with the pyramidal structure that matches inside conical shell, screw 6 and pass through 1 side of hopper The left end of wall, screw 6 passes through 2 stationary hopper 1 of nut group.

In the present embodiment, maximum angle is 90 degree between conical shell bus in the first gasket 5, and the diameter of small nozzle is 12.5mm, the diameter of annular baffle are 60mm, and the material of the first gasket 5 is mild steel.Screw 6 is to be adapted with the first gasket 5 Hexagon socket countersunk flat cap head screw 6.
