Embodiment 1

[0034] Production of middle slot 7:

[0035] A. First mix 50% ethanol and purified water, then add 2% coupling agent KH570 to form a dilution solvent, and then pour 6 parts of silicon carbide, 7 parts of corundum, 6 parts of fly ash and 5 parts of glass beads into the dilution solvent After soaking in the solvent tank for 30 minutes, take it out, dry it and mix it, and then add the following components according to the following mass parts: 100 parts of UPE, 12 parts of flame retardant HF-UPE, 10 parts of antistatic agent E-1228, After 2 parts of graphite and 2 parts of PE wax are blended and crosslinked, put them into the screw extruder for extruding, demoulding, cooling and forming, the set temperature is 220°C, and the screw speed is 15Hz;

[0036] B. Hot-melt connection between the E-shaped groove side 13 and the middle plate 10:

[0037] First put the E-shaped groove side 13 and the middle plate 10 prepared in step A into corresponding hot-melt molds respectively, and th...

Embodiment 2

[0040] Production of scraper 11:

[0041] 100 parts of UPE, 12 parts of flame retardant HF-UPE, 10 parts of antistatic agent E-1228, 10 parts of silicon carbide, 8 parts of glass beads, 7 parts of corundum, 2 parts of graphite, and 2 parts of PE wax are used as raw materials. After blending and crosslinking, it is put into the feed port of the screw extruder, extruded by the screw extruder unit, cooled and shaped, demolded, and drawn and cut. The extrusion temperature of the screw extruder is 190°C, extrusion speed 5-15Hz, extrusion pressure 5-25Mpa.

Embodiment 3

[0043] Production of chain splitter 5:

[0044] 100 parts of TPU, 15 parts of flame retardant, 10 parts of antistatic agent, 10 parts of corundum, 10 parts of silicon carbide, and 2 parts of color masterbatch (TU2015) are used as raw materials. After blending and crosslinking, they are put into the injection molding machine for feeding In the mouth, after being heated and melted by the barrel screw of the injection molding machine, it is injected into the mold cavity to fill, maintain pressure and demould. The injection molding temperature is 200°C and the injection molding pressure is 30Mpa.

[0045] The chain splitter 5 of this embodiment, the chain splitter 5 is fixed on the mandrel of the machine head 1, one end of the mandrel is inserted into the two holes on the chain splitter 5, and the other end is inserted into the support plate of the two side walls of the machine head frame. Lock the mandrel with a cotter pin on the outside of the support plate in the hole. Because...

Abstract

The invention relates to a low-weight scraper conveyer. The low-weight scraper conveyer comprises a machine head, a machine tail and a machine body which is connected between the machine head and the machine tail. The machine head comprises a power unit, a chain distributor and a shaft protecting plate. The machine body comprises a plurality of middle grooves which are connected end to end, and a scraper chain which is composed of a circular chain and a scraper. The middle grooves comprise E-shaped groove ledges, middle plates and steel tubes. The two side edges of the middle plates are connected into grooves in the positions of middle protrusions of the corresponding E-shaped groove ledges in an inserting mode. Through holes are formed in the centers of the groove walls of the E-shaped groove ledges. The steel tubes are arranged in the through holes, and every two adjacent middle grooves are connected with coupling shafts through the steel tubes in the through holes of the centers of the E-shaped groove ledges. The shaft protecting plate is installed above the chain distributor, and the shaft protecting plate and an upper groove and middle groove of a machine head rack are located on the same plane. The chain distributor is arranged on a central spindle at the rear side of a machine head chain wheel, and directly faces the lower side of the shaft protecting plate. The low-weight scraper conveyer has the advantages that acid-base resistance and abrasion resistance are achieved, the shrinkage ratio performance of all parts is good, the weight is low and the machine head is free of storage. Compared with a steel scraper conveyer, the accident rate is lowered by more than 70%.

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery equipment, and in particular relates to a light scraper conveyor. Background technique [0002] The most commonly used transportation equipment in the production process of coal mining and transportation in coal mines is the scraper conveyor. At present, the scraper conveyor is made of steel. Problems such as short service life and frequent accidents have seriously affected the efficiency of coal transportation, brought inconvenience to safety production management, increased production costs, and brought many safety hazards. At the same time, the steel scraper conveyor is time-consuming, inefficient, and difficult to transport and remove, which increases the work intensity of workers underground. With the continuous improvement of coal mining volume, the problem of increasing coal cargo volume and reducing scraper conveyor accidents has become increasingly prominent. At the same t...
