Increase mining machine material space anti-sticking chain conveyor Technical Field The invention belongs to the field of machinery, and particularly relates to an anti-blocking chain conveying device for a material passing space of a mining machine. Background The existing coal cutter heading machine in mining industry is key equipment for mining, the matched conveyor is a chain pulling scraper type, The conveyor device from the shovel plate of the tunneller to the rear part of the body frame for mining is basically an annular chain scraper machine, and the conveyor device for the lower part of the coal mining machine is basically an annular chain scraper machine, so that the practice proves that the sliding friction annular chain scraper machine has the following serious defects: ① In the actual use process, as the materials and the blocks are large and hard, when the annular chain pulls the scraping plates to transport materials, hard gangue, sulphur stones, iron ores, rocks and other blocks are often plugged between the annular chain and the scraping plate pressing plate, also are often plugged between the annular chain and the scraping plate supporting bottom plate and are plugged at the bottom of the scraping plate, so that the annular chain and the scraping plate pressing plate are mutually blocked, the scraping plate and the scraping plate pressing plate are blocked, the power can not drive the annular chain and the scraping plate to work, even the motor is overloaded and damaged, and serious losses such as frequent maintenance, shutdown and production stopping are caused; ② The annular chain scraper conveyor is used for conveying materials in a material conveying mode by driving the scraping plate to slide, rub and scrape the materials, and the power system is inevitably enlarged due to frequent material clamping and sliding friction of the conveyed materials, so that energy is wasted, and huge loss is caused due to frequent damage; ③ In order to be suitable for high-power, the annular chain is made to have a large volume to increase strength, and the height of the annular chain is only 70-300 mm, so that the height of the scraper conveyor is increased; ④ In order to prevent the annular chain from jumping, a sliding friction chain pressing plate groove of a compression ring chain with complex structure and high strength and a chain pressing scraper blade is formed in the upper part of the annular chain, so that a material passing channel of a tunneling machine body frame and a material passing channel of the lower part of the coal mining machine are occupied in a large amount, materials are frequently clamped in a double-chain pressing scraper groove of a scraper machine due to the large depth of the chain pressing scraper groove (generally 90-330 mm), sliding friction resistance is further increased by the clamped scraper, the chain and the chain pressing scraper groove, driving power is further increased to overcome the friction resistance, serious equipment space and kinetic energy are wasted, the excavated and dropped materials cannot be rapidly and smoothly transported out, and production efficiency is greatly reduced; ⑤ In order to reduce dust in mining, water spraying and spraying are necessarily used, so that the water content of materials is high, the materials are adhered and hardened on an annular chain and a scraping plate, the return materials of a scraping belt are serious when the annular chain pulls the scraping plate to circulate to the lower part of a scraping plate supporting plate, the belt trough body under the scraping plate is often hardened and blocked by returned water-containing coal slime, stone powder, lump materials and the like, and a large amount of hardened materials are locked on the scraping plate and the annular chain, so that the scraping plate cannot work, and the motor is often damaged frequently due to overload starting and the like; ⑥ The scraper conveyor cannot be provided with a middle groove side guide wheel and a power shaft guide wheel and a limit wheel, and is also provided with a double-shaft nail belt as a conveyor in the body frame, because the longitudinal width of the double-shaft nail belt is large, and the turning radius of the double-shaft nail belt is large, the double-shaft nail belt is provided with at least more than six multi-tooth nail belts with a plurality of hanging lugs in each row, which are buckled left and right, and are connected front and back, a shovel plate of the tunneling machine is required to be stuck with a ground shovel material smoothly, so that the shovel plate is required to be thinner and better, the thickness of the shovel plate is increased due to the large turning radius of the double-shaft nail belt, the shovel plate is difficult to shovel material, the connecting height of the shovel plate and the body frame is increased, the passing space of the body frame is lower, and gap-shaped leakage of the buckled parts of
