Abstract

The invention discloses a novel replaceable tearing-off knife which comprises a knife body and a knife head, wherein the knife body and the knife head are made of different materials, the knife head is fixed on the knife body by rivets, and the knife head is made of an impact-resistant and high-wear-resistant material.

Description

Novel interchangeable tears sword open

Technical Field

The invention relates to a tearing knife, in particular to a novel replaceable tearing knife.

Background

The tearing machine is used as key equipment of the sugar manufacturing process of the sugar refinery, and the sugar yield and the production cost are directly influenced by the tearing capacity. The tearing knife is equivalent to the teeth of the whole sugar refinery pipeline digestive system, and the function of the tearing knife is very important. At the present stage, because the sugarcane is generally loaded by the sugarcane grabbing machine, more stones, ironware and other impurities are mixed in the sugarcane than manual loading, the traditional bag welding type tearing knife is not enough in hardness and wear-resistant, so that the tearing knife is easy to tip, the problems of the sugarcane processing capacity reduction and the low sugar yield of a sugar factory caused by passivation are frequent, the sugar factory has to stop for changing the sugarcane, the maintenance or replacement operation is complex, the time is long, and the normal production is greatly influenced.

At present, most of the tearing knives in sugar mills adopt a structure that a layer of wear-resistant material is welded on the head part of a common steel knife body, a small amount of structural modes that an alloy knife head and the knife body are welded are adopted, and an assembly structure adopting an exchangeable mode is not available.

The head part of the common steel cutter body is welded, the area of the cutter tip part of the sugarcane cutter is small, and acceptable surfacing wear-resistant materials are few. The tool tip is the most stressed part and is worn the fastest, so the problem of wear resistance of the tool tip is not well solved by a surfacing method; most of the sugarcane knives are made of 45# steel or A3 steel, so that the hardness of the sugarcane knives is not very high, and when the knife points touch harder objects such as stones or iron blocks, the knife points are easy to crack, the gap between the sugarcane knives and the conveying belt is increased, and the pressing quality is unstable. The structure that adopts alloy tool bit and cutter body seam, the blade of sugarcane sword is inlayed and is had carbide for the blade of sugarcane sword increases hardness, and although the blade of sugarcane sword hardness is high, though the wear resistance is good but shock resistance is not good enough because carbide body fragility is too high.

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide a novel replaceable tearing knife which comprises a knife body and a knife head, wherein the knife body and the knife head are made of different materials, the knife head is fixed on the knife body by rivets, and is made of an impact-resistant and high-wear-resistant material.

The invention adopts the specific technical scheme that:

the utility model provides a novel interchangeable formula tears sword of untiing, includes cutter body and tool bit, be equipped with the flange on the cutter body, the tool bit is the recess shape, the cutter body with the tool bit is in through the mode of unsmooth tang connect on the flange to through fix with rivet.

Furthermore, a notch is formed in the head of the flange, and the head of the cutter head is clamped at the notch and is fixed to prevent the cutter head from moving left and right.

Furthermore, two inner side surfaces of the groove of the cutter head are in contact with two side surfaces of the flange, the inner top surface of the cutter head is in contact with the top of the flange, through holes are formed in the cutter head and the flange in a matched mode, and the rivet penetrates through the through holes to fixedly connect the cutter head and the cutter body.

Further, the cutter body with the tool bit adopts different materials preparation, the tool bit adopts wear-resisting, shock-resistant material preparation.

The invention has the beneficial effects that: according to the tearing-off knife provided by the invention, when the knife head is abraded, the knife head can be directly detached from the knife body and quickly replaced, the whole tearing-off knife does not need to be detached from the knife set rod, the knife body does not need to be detached and replaced, and the production cost and the replacement labor cost of the knife body are saved. The cutter head and the cutter body are fixed through the rivet, the cutter head can be quickly replaced after being partially worn and cannot be used, and the working efficiency is greatly improved. And through the cutter body breach, the mounting means that face and face contacted for the tool bit obtains 6 direction restraints about from top to bottom on the cutter body, thereby effectually prevents that the tool bit from droing.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment provides a novel replaceable tearing knife, as shown in fig. 1-4, which comprises a knife body 1 and a knife head 2, wherein the knife body 1 is provided with a flange, the knife head 2 is in a groove shape, and the knife body 1 and the knife head 2 are connected on the flange in a concave-convex spigot manner and are fixed through rivets 3. Specifically, two inner side surfaces 25 of the groove of the cutter head 2 are in contact with two side surfaces 14 of the flange, an inner top surface 22 of the cutter head 2 is in contact with the top 12 of the flange, the cutter head 2 and the flange are provided with through holes in a matching manner, and the rivet 3 penetrates through the through holes to fixedly connect the cutter head 2 and the cutter body 1. And the head part of the flange is provided with a notch 13, and the head part 24 of the cutter head 2 is clamped at the notch 13 to fix the cutter head 2 to prevent the cutter head from moving left and right. Through the installation mode, the cutter head 2 is restrained in 6 directions of the upper part, the lower part, the left part, the right part, the front part and the rear part on the cutter body 1, so that the cutter head 2 is effectively prevented from falling off. When the tool bit 2 is disassembled, the tool bit can be replaced only by taking down the rivet 3, and the tool body 1 does not need to be replaced, so that the tool bit has the advantages of time saving, convenience in replacement and cost saving.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
