Embodiment 1

[0034] Production of the middle groove 7:

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

[0036] B, E-shaped groove bank 13 and middle plate 10 hot melt connection:

[0037] First, put the E-shaped groove side 13 and the middle plate 10 prepared in step A into the corresponding hot-melt molds respectively. There are four hydraulic oil-filled symmetrical...

Embodiment 2

[0040] Production of scraper 11:

[0041] It is based on 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 as raw materials. After being blended and cross-linked, it is put into the feed port of the screw extruder, and it is extruded by the screw extruder unit, cooled and shaped, demoulded, and drawn and cut. The extrusion temperature of the screw extruder is 190℃, extrusion speed 5-15Hz, extrusion pressure 5-25Mpa.

Embodiment 3

[0043] Production of chain splitter 5:

[0044] It is made of 100 parts of TPU, 15 parts of flame retardant, 10 parts of antistatic agent, 10 parts of corundum, 10 parts of silicon carbide, 2 parts of color masterbatch (TU2015) as raw materials, which are blended and cross-linked and put into the injection injection molding machine. In the mouth, after heating and melting by the barrel screw of the injection molding machine, it is injected into the mold cavity to be filled, pressure-maintained and demolded. The injection temperature is 200℃ and the injection pressure is 30Mpa.

[0045] In 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 divider 5, and the other end is inserted into the support plates on both side walls of the machine head frame. In the hole, lock the mandrel with a split pin on the outside of the support plate. Since the chain splitter 5 in the present invention ...

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 and equipment, and specifically relates to a lightweight scraper conveyor. Background technique [0002] The most commonly used transportation equipment in the production process of coal mining and transportation is the scraper conveyor. At present, the scraper conveyor is made of steel, which has the advantages of heavy volume, small transportation capacity, high power, high energy consumption, poor corrosion and wear resistance, Problems such as short service life and many accidents have seriously affected the efficiency of coal transportation, brought inconvenience to safe production management and increased production costs, as well as many hidden safety hazards. At the same time, the steel scraper conveyor takes a long time to move and remove, and is low in efficiency and difficult, which increases the intensity of workers in underground operations. With the continuous increase of c...
