Abstract

The utility model of whole tyre breaker wear device involves an important part which can break the scrap tyre into rubber blocks. The knife of the whole tyre breaker is made by resurfacing welding about 3 to 5 mm thick of cemented carbide on the common basal body and has disadvantages of short service life, etc. The utility model of whole tyre breaker wear knife is characterized in that the blade (3) is of elliptical shape, 2 to 4 cutter heads (7) are welded on the basal body (8), cutter head (7) is of rectangle shape, and is made by high hardness cemented tungsten carbide, a plurality of rectangular protection plates (9) of high hardness cemented tungsten carbide are welded on the blade (3) excircle. As high wear-resistant materials are used in the wearing parts of the whole tyre breaker, the impact resistance of the device is improved, an the reliability and abrasion resistance is enhanced greatly, the breaker can break various tyres including rail radial tyre, and the breaker has advantages of long service life and strong impact resistance.

Description

The wear-resistant device of whole tyre breaking machine

One, technical field

The wear-resistant device of the utility model whole tyre breaking machine relates to an a kind of strength member that junked tire is broken into the crushing mechanism of block rubber.

Two, background technology

Develop rapidly along with global highway and auto industry, the recovery and the processing that are called as the junked tire of " black pollution " day by day become a great worldwide environmental protection difficult problem.According to incompletely statistics, calendar year 2001 China's junked tire generation reach more than 5,000 ten thousand, but China can only dispose about 2,600 ten thousand to 3,000 ten thousand of junked tire every year, remaining more than 2,000 ten thousand junked tire can not get effective utilization; Other countries also in various degree appearance analogue, by the end of 1997, world's junked tire burden reached more than 30 hundred million, and also continued to produce about 1,000,000,000 junked tires every year.

Steel wire meridian tire is adopted by increasing user vehicle because its long service life, and in China, steel wire meridian tire has accounted for more than 50% of tire sum, and in the ratio of U.S.'s steel wire meridian tire up to more than 90%.In the recycling of junked tire, steel wire meridian tire becomes " difficulty in the difficulty " in the junked tire recycling owing to its tyre surface contains netted steel wire floor, the steel scrap silk radial tyre of China does not still have recycling, is no more than 10% in the ratio of its utilization of the U.S. yet.

Whole tyre breaking machine is a kind of crushing mechanism that junked tire is broken into block rubber.At present, the cutter of whole tyre breaking machine is to process after being about the carbide alloy of 3～5mm at built-up welding one bed thickness on the common matrix, and its case hardness is no more than HRC62.And whole tyre breaking machine is at the broken worn-out tire particularly during steel wire meridian tire, the cutter part (cutter head and side) that contacts with material is subjected in steel wire, fibrage and the tire in the tire effects such as intense impact, friction, extruding of impurity such as inevitable iron nail all the time, the cutter head of universal cutter and side are because case hardness is low, wear resistence is poor, wearing and tearing are extremely fierce, general every work is after 150～200 hours, again built-up welding cutter, the phenomenon that has caused the output of whole production line not increase.

Three, summary of the invention

The shortcoming that exists at the universal cutter of above-mentioned whole tyre breaking machine, the technical scheme of the utility model technical issues that need to address and proposition is to overcome the defective that prior art exists, and the wear-resistant device of the whole tyre breaking machine of a kind of strong shock resistance, long service life is provided.

Main technical schemes of the present utility model is: whole tyre breaking machine mainly is made up of casing (1), running part (2), blade (3), roll (4), driving shaft (5), driven shaft (6) etc., blade (3) and roll (4) form crushing auxiliary, roll (4) be shaped as circle, some blades (3) and roll (4) are housed on the driving shaft (5), a slice roll (4) is housed in the middle of per two blades (3), and the cutter head (7) of blade (3) shape is in the shape of a spiral arranged; Some blades (3) and roll (4) also are housed on the driven shaft (8); a slice roll (4) is housed in the middle of per two blades (3); the cutter head (7) of blade (3) is shape arrangement in the shape of a spiral also; the wear resistant cutters of whole tyre breaking machine is characterized in that the ellipse that is shaped as of blade (3); be welded with 2～4 cutter heads (7) above the matrix (8); cutter head (7) be shaped as rectangle; its material is the high-hardness tungsten carbide carbide alloy, also is welded with some rectangle high-hardness tungsten carbide carbide alloy screening glass (9) on the periphery of blade (3).

Advantage of the present utility model: also be welded with some rectangle high-hardness tungsten carbide carbide alloy screening glass (9) on high-hardness tungsten carbide carbide alloy, the periphery because the cutter head (7) of blade (3) has adopted; promptly in the consumable accessory of whole tyre breaking machine, used high abrasion resisting material; improved the impact resistance of equipment; so greatly improved reliability and wearability; can pulverize various tires and comprise steel wire meridian tire, have advantages such as service life of equipment is long, anti-impact force is strong.

Four, description of drawings

Fig. 1 is the structural representation of whole tyre breaking machine.Among the figure: 1, casing; 2, transmission device.

Fig. 2 is the A-A cutaway view of Fig. 1.Among the figure: 3, blade; 4, roll; 5, driving shaft; 6, driven shaft.

Illustrate: some blades (3) and roll (4) are housed on the driving shaft (5), a slice roll (4) is housed in the middle of per two blades (3), the cutter head (7) of blade (3) shape is in the shape of a spiral arranged; Some blades (3) and roll (4) also are housed on the driven shaft (8), a slice roll (4) is housed in the middle of per two blades (3), the cutter head (7) of blade (3) is shape arrangement in the shape of a spiral also.

Fig. 3 is the structural representation of the utility model wear-resistant device.Among the figure: 7, cutter head; 8, matrix; 9, Talide screening glass.

Five, the specific embodiment

Below in conjunction with Fig. 1 and Fig. 2; implementation process of the present utility model is described further: driving shaft (5) drives blade (3) and roll (4) is made low speed rotation; driven shaft (6) drives blade (3) by transmission device (2) and roll (4) is done opposite spin with respect to driving shaft (5); blade (3) and roll (4) form crushing auxiliary; be welded with 2～4 cutter heads (7) above the matrix (8) of blade (3); the material of cutter head (7) is the high-hardness tungsten carbide carbide alloy, also is welded with some rectangle high-hardness tungsten carbide carbide alloy screening glass (9) on the periphery of blade (3).After material adds above equipment, at first hooked to enter by the cutter head (7) on the blade (3) and pulverize the district, owing to be subjected to powerful effect such as push, pull, material is broken.Because cutter head, periphery in blade and material contact portion have all adopted high abrasion resisting material, so greatly improved wearability when broken tire, have prolonged the service life of whole tyre breaking machine.
