Abstract

The utility model discloses a shell ring for screw conveyer, including shell ring and wearing layer, the shell ring is formed by upper half cylinder festival and lower half cylinder festival welding, the external diameter that upper half cylinder saved and lower half cylinder saves is unanimous, and the section of thick bamboo wall of lower half cylinder festival is thinner than the wall that upper half cylinder saved, the wearing layer comprises the wear resistant strip that the width is the same, the even welding of wear resistant strip is on the lower half cylinder inner wall of festival, and lower half cylinder is all covered by wear resistant strip the festival. The utility model discloses fall into the wear resistant strip that quantity is certain with the wearing layer to save the beading with lower half cylinder respectively, avoided the protruding problem of wearing layer. The utility model discloses simple structure easily processes and installs.

Description

A kind of conveying worm shell ring

Technical field

This utility model is related to a kind of conveying worm shell ring, belongs to technical field of conveying machinery.

Background technology

For conveying worm, for preventing the abrasion of shell ring itself, typically generally can adopt in the internal wear-resisting layer covering of shell ring In two ways：One is to be fastened by bolt, and this mounting means needs to hole on shell ring, then tight using bolt Gu, its workload is big, material waste is big；Two is directly to weld together wearing layer periphery and shell ring, and this welding manner is made Become wear-resisting layer height not on same circumference, during work, make concentrated wear serious.

Content of the invention

Technical problem to be solved in the utility model is the defect existing for prior art, provides a kind of helical feed Machine shell ring.

For solving this technical problem, this utility model provides a kind of conveying worm shell ring, including shell ring and resistance to Mill layer, described shell ring is formed by upper half shell ring and lower half shell ring welding, and described upper half shell ring is consistent with the external diameter of lower half shell ring, under The barrel of half shell ring is thinner than the barrel of upper half shell ring；Described wearing layer is made up of the same wear rib of width, and described wear rib is equal On the even inwall being welded on lower half shell ring, lower half shell ring is all covered by wear rib.

Described upper half shell ring and lower half shell ring are rolled using the steel plate of different-thickness and form.

Beneficial effect：Wearing layer is divided into the certain wear rib of quantity by this utility model, and direct with lower half shell ring respectively Welding, it is to avoid the projection problem of wearing layer.This utility model structure is simply it is easy to processing and installing.

Brief description

Fig. 1 is structural representation of the present utility model.

In figure：1 upper half shell ring, 2 lower half shell rings, 3 wear ribs.

Specific embodiment

Below in conjunction with the accompanying drawings and embodiment specifically describes to this utility model.

Fig. 1 show structural representation of the present utility model.

This utility model includes shell ring and wearing layer.

Described shell ring is formed by upper half shell ring 1 and lower half shell ring 2 welding, the external diameter of described upper half shell ring 1 and lower half shell ring 2 Unanimously, the barrel of lower half shell ring 2 is thinner than the barrel of upper half shell ring 1.

Described upper half shell ring 1 and lower half shell ring 2 are rolled using the steel plate of different-thickness and form.

Described wearing layer 3 is made up of the same wear rib of width, and described wear rib uniform welding is in the inwall of lower half shell ring 2 On, lower half shell ring 2 is all covered by wear rib.

Described wear-resisting strip material adopts wear-resistant composite board 6+5 (being made up of basic unit and wearing layer).

The Wall-Thickness Difference of described upper half shell ring 1 and lower half shell ring 2 and wearing layer 3 consistency of thickness.

Processing method of the present utility model comprises the steps：

1) rolled using sheet metal and make lower half shell ring 2；

2) rolled using steel plate and make upper half shell ring 1；

3) high-abrasive material is processed into width unanimously, the length wear rib isometric with shell ring；

4) wear rib is uniformly paved with lower half shell ring 2 internal layer, on welding lower half shell ring 2；

5) by step 4) lower half shell ring 2 and upper half shell ring 1 weld together, make conveying worm shell ring.

Wearing layer is divided into the certain wear rib of quantity by this utility model, and directly welds with lower half shell ring respectively, it is to avoid The projection problem of wearing layer.Solve in the big workload and wearing layer circumference being caused using bolt fastening in prior art The concavo-convex concentrated wear causing is serious, the shell ring of protection and material contact portion.This utility model structure simple it is easy to processing and Install.

This utility model the embodiment above, is merely illustrative, and is not only, all in the range of this utility model Or the change in the range of equivalent this utility model all surrounded by this utility model.
