Problems solved by technology
In this way of operation, on the one hand, the proportion of sand and gravel to cement and accelerator cannot be accurately guaranteed due to the inaccurate measurement of the sand and gravel. The pulp rebounds greatly, and the quality of the injection surface cannot be guaranteed
The stirred shotcrete mixture still needs to be manually loaded into the hopper of the concrete spraying machine, which further increases the labor intensity
The whole feeding and mixing process is extremely labor-intensive, and the mixing quality cannot be guaranteed, which seriously reduces the injection quality

The invention belongs to the technical field of underground concrete construction equipment of a coal mine. Feeding and stirring equipment for coal mine concrete spraying comprises a rack, a horizontal stirring machine, a first overturning driving part, a shoveling and feeding hopper and a remote control unit, wherein an overturning swing arm is fixedly arranged on one side of the horizontal stirring machine; a hinged support is arranged on the rack and on the other side of the horizontal stirring machine; the shoveling and feeding hopper is hinged to the hinged support through a second hinged shaft, and is provided with a second overturning driving part for driving the shoveling and feeding hopper to overturn and swing; and the remote control unit comprises a remote control receiver and a remote control transmitter. The invention further discloses a feeding, stirring and spraying method for coal mine concrete spraying. According to the feeding and stirring equipment for coal mine concrete spraying and the feeding, stirring and spraying method, the practicability of the product can be greatly improved, remote control is realized, potential safety hazards caused by operation of personnel at the side part of a vehicle are avoided, the equipment can adapt to operation in a narrow underground roadway, the operation safety is improved, and by use in cooperation with a guniting machine, mechanization and automation of underground concrete spraying operation of the coal mine are realized.
Description
technical field [0001] The invention belongs to the technical field of underground concrete construction equipment in coal mines, and in particular relates to a material feeding and mixing equipment and a spraying method for coal mine concrete spraying. Background technique [0002] At present, in the concrete spraying support operation of the coal mine, due to the many transportation links and the long cycle, it is impossible to mix the sand, gravel and cement evenly on the ground before transporting them to the concrete spraying operation site of the coal mine. Generally, the sand and gravel are stirred evenly on the ground and then transported to the underground of the coal mine and unloaded to the ground. Because the coal mine roadway space is generally relatively narrow, large concrete batching and feeding equipment cannot be used. When spraying is required, manually mix the sand and gravel with cement and quick-setting agent and then stir. In this way of operation, o...
