Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of unloading machine accessories, and particularly relates to a detachable blade vertical spiral shaft for an unloading machine. BACKGROUND

[0002] The spiral unloading machine is a machine for unloading, and the working principle of the unloading machine is to use a spiral as a propeller, and when the spiral rotates in a material pile, the material at the contact position with the spiral is sent out of the car box by the spiral. The unloading machine improves the unloading efficiency, can adapt to different vehicle models, has high flexibility, and the spiral blade is deformed and worn to different degrees during long-time use, needs to be replaced regularly, the conventional spiral includes a mandrel and a spiral blade, the spiral blade is welded and fixed on the outer side wall of the mandrel, the existing spiral is replaced integrally or the corresponding damaged spiral blade is cut, the maintenance of this kind of mode is complex, time-consuming and laborious, and the mandrel is easily deformed, which is not conducive to the subsequent normal use.

[0003] Therefore, how to provide a detachable blade vertical spiral shaft without affecting the use of the mandrel is a problem to be solved by those skilled in the art. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the utility model provides a detachable blade vertical spiral shaft for an unloading machine, which is convenient to replace the blade and does not damage the mandrel, and does not affect the subsequent use of the spiral.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a detachable blade vertical spiral shaft for an unloading machine, which comprises:

[0006] A mandrel, a mounting strip plate is spirally fixed on the outer side wall of the mandrel, and a plurality of bolt holes are arranged at intervals on the mounting strip plate;

[0007] A spiral blade, a plurality of connecting holes are arranged at intervals in the region close to the inner side of the spiral blade, the connecting holes are connected with the bolt holes by bolts, the spiral blade is fixed on the mounting strip plate by the bolts, and a plurality of groups of spiral blades are arranged in the tail-to-head mode on the outer side of the mandrel.

[0008] The utility model has the advantages that the outer side of the mandrel is provided with the mounting strip plate, the mounting strip plate provides the mounting basis of the spiral blade on the mandrel, the size of the mounting strip plate protruding on the outer side of the mandrel is small, the mounting requirement of the spiral blade is met, when the spiral blade is damaged and needs to be replaced, the original spiral blade does not need to be cut, only the old part needs to be disassembled and replaced with a new spiral blade, the cutting and welding process is not needed, the installation efficiency is high, and the use cost is low.

[0009] Preferably, the region close to the outer side of the spiral blade is formed with a wear-resistant layer by surfacing.

[0010] The technical effect produced by this is that the wear-resistant layer arranged on the spiral blade member can prolong the service life of the spiral blade member, reduce the replacement frequency, and reduce the use cost of the component to a certain extent.

[0011] Preferably, the wear-resistant layer comprises a first covering part, a second covering part and a third covering part, the first covering part is located on the top surface of the spiral blade member, the second covering part is located on the side surface of the spiral blade member, and the third covering part is located on the bottom surface of the spiral blade member.

[0012] The technical effect produced by this is that the outer side area of the spiral blade member is most seriously worn by the material during unloading, so that the wear-resistant layer is additionally arranged in this area to reduce the friction loss of the spiral blade member to the material, and the structural strength of the spiral blade member is also enhanced to a certain extent, and the spiral blade member is not easy to deform.

[0013] Preferably, the extension distance of the first covering part towards the inner side of the spiral blade member is greater than the extension distance of the third covering part towards the inner side of the spiral blade member.

[0014] The technical effect produced by this is that the upper side surface of the spiral blade member is the main bearing surface during unloading, and the friction loss is relatively large compared with the lower side surface, so that a larger area of the upper side surface of the blade member is covered to reduce the friction loss of the blade member to the material.

[0015] Preferably, there is a gap between the inner side wall of the spiral blade member and the outer side wall of the mandrel.

[0016] The technical effect produced by this is that the gap between the inner side of the spiral blade member and the mandrel facilitates the installation of the spiral blade member, and avoids the problem that the spiral blade member and the mandrel cannot be effectively installed due to too small gap.

[0017] Preferably, the area of the mandrel corresponding to the installation of the strip plate is a blade dismounting section, the blade dismounting section extends to both ends of the mandrel, or the mandrel is divided into a blade dismounting section and a blade non-dismounting section, and the spiral blade member in the blade non-dismounting section is fixedly welded on the outer side wall of the mandrel.

[0018] The technical effect produced by this is that in specific implementation, the mandrel can be a global section blade dismounting section, or a local blade dismounting section, which can be adjusted according to the use environment and the unloaded material. BRIEF DESCRIPTION OF DRAWINGS

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Refer to the drawings of the utility model Figs. 1 to 3 According to the detachable blade vertical spiral shaft for a car dumper provided by the embodiments of the utility model, which comprises:

[0025] The mandrel 1 is provided with the mounting strip 2 fixed spirally on the outer side wall, and the mounting strip is actually a long rectangular plate, which is spirally arranged on the outer side wall of the mandrel in a deformed manner. The mounting strip can be welded and fixed on the mandrel. The mounting strip 2 is provided with a plurality of bolt holes 3 at intervals, and the interval direction of the bolt holes 3 corresponds to the spiral direction.

[0026] The spiral blade piece 4 is provided with a plurality of connecting holes 6 at intervals in the area close to the inner side, and the connecting holes 6 are connected with the bolt holes 3 through bolts. The spiral blade piece 4 is fixed on the mounting strip 2 through the bolts. The spiral blade piece 4 has a plurality of groups, and the groups of spiral blade pieces 4 are arranged at the outer side of the mandrel 1 in a head-to-tail mode to form a continuous spiral blade.

[0027] In some other embodiments, the area close to the outer side of the spiral blade piece 4 is formed with a wear layer 5 by using wear-resistant material to build up welding. The wear-resistant material can be hard alloy.
