[0002] Mine backfilling is a mining method that uses backfill materials to support the surrounding rock of the goaf. Ground pressure control is achieved through two-step mining of the stope and pillars. It is suitable for metal ore bodies and deposits with complex hydrogeological conditions.

[0003] A feeder is a machine used to store and supply filling slurry. By using the feeder and filling pump together, the slurry is transported and filled. However, when using existing feeders, the feeder is large in size and has a high working height, which makes it inconvenient to inject slurry. Moreover, during the filling process, when slurry is added and filled at the same time, the slurry cannot be mixed well, which can easily cause solidification and clumping, affecting the filling effect. Utility Model Content

[0004] The purpose of this utility model is to provide a material feeding machine for filling slurry in underground mines, so as to solve the problems mentioned in the background art, such as the inconvenience of slurry injection and the inability of slurry to mix well when slurry is added and filled at the same time during the filling process.

A support frame is provided on the outer surface of the silo. A discharge pipe is connected to the bottom end of the silo. A cover plate is bolted to the top of the silo. A feed pipe is connected to the surface of the cover plate. A conveying cylinder is connected to the surface of the feed pipe. A feed silo is connected to one end of the conveying cylinder. A motor is provided at the end of the conveying cylinder away from the feed silo, and a spiral auger is fixedly connected to the output shaft of the motor.

[0006] Preferably, the output shaft of the stirring motor is fixedly connected to the stirring rod through the cover plate, and a retaining ring is fixedly connected to the inner wall of the hopper, with a connecting groove through the surface of the retaining ring.

[0007] Preferably, the stirring rod consists of two parts: one part is a long rod and the other part is a horizontal rod. The stirring rod is activated inside the hopper by a stirring motor.

[0008] Preferably, the retaining rings are evenly distributed on the inner wall of the hopper, and the effective width of the retaining rings increases sequentially from top to bottom.

[0009] Preferably, the connecting grooves are evenly distributed on the surface of the retaining ring, and the length of the connecting grooves on the retaining rings at different positions in the hopper increases sequentially.

[0010] Preferably, the conveying cylinder is connected to the hopper via a feed pipe, and the interior of the feed hopper is hollow.

[0011] Preferably, the auger is rotatably connected to the conveyor cylinder via a motor on the conveyor cylinder, and the auger acts below the feed hopper via the conveyor cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the connection between the hopper and the cover plate, and the connection between the cover plate and the feed pipe, and the connection between the feed pipe and the conveying cylinder, the slurry in the hopper is easily replenished under the action of the feed hopper and the conveying cylinder. Under the rotational connection of the screw conveyor and the conveying cylinder, the slurry is easily transported and mixed. Under the action of the mixing motor and the mixing rod, the slurry mixing performance is further improved, and its filling effect and performance are improved.

[0013] 2. By connecting the hopper and the baffle ring, the baffle ring can block the falling slurry and slow down the falling speed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A material feeding machine for filling slurry in underground mines includes a hopper 1 and a mixing motor 21. A support frame 11 is provided on the outer surface of the hopper 1. A discharge pipe 12 is connected to the bottom of the hopper 1. A cover plate 2 is bolted to the top of the hopper 1. A feed pipe 33 is connected to the surface of the cover plate 2. A conveying cylinder 3 is connected to the surface of the feed pipe 33. A feed hopper 31 is connected to one end of the conveying cylinder 3. A motor is provided at the end of the conveying cylinder 3 away from the feed hopper 31, and the output shaft of the motor is fixedly connected to a spiral auger 32. Through the connection between the hopper 1 and the cover plate 2, and the connection between the cover plate 2 and the feed pipe 33, and the connection between the feed pipe 33 and the conveying cylinder 3, the rotational connection between the conveying cylinder 3 and the spiral auger 32, in conjunction with the use of the feed hopper 31, realizes the filling operation of the slurry in the hopper 1.

[0018] Furthermore, the output shaft of the stirring motor 21 is fixedly connected to the stirring rod 22 through the cover plate 2, and the inner wall of the silo 1 is fixedly connected to the retaining ring 4. The surface of the retaining ring 4 is provided with a connecting groove 41. Through the connection between the cover plate 2 and the stirring motor 21, the mixing and stirring operation of the slurry in the silo 1 is realized under the connection between the stirring motor 21 and the stirring rod 22.

[0019] Furthermore, the stirring rod 22 consists of two parts: one part is a long rod and the other part is a horizontal bar. The stirring rod 22 acts inside the hopper 1 through the stirring motor 21. Through the connection between the stirring rod 22 and the output shaft of the stirring motor 21, the horizontal bar-shaped stirring rod 22 acts on the upper surface of the retaining ring 4 to achieve the effect of fully mixing the materials.

[0020] Furthermore, the baffle rings 4 are evenly distributed on the inner wall of the hopper 1. The effective width of the baffle rings 4 increases from top to bottom. Through the connection between the baffle rings 4 and the hopper 1, the falling speed of the slurry in the hopper 1 is effectively slowed down under the action of the baffle rings 4, so that the mixing rod 22 can better perform mixing operations.

[0021] Furthermore, the connecting grooves 41 are evenly distributed on the surface of the retaining ring 4. The length of the connecting grooves 41 on the retaining ring 4 at different positions in the hopper 1 increases sequentially. Through the connection between the connecting grooves 41 and the retaining ring 4, the stirring rod 22 can be easily taken out and put into the hopper 1 under the action of the connecting grooves 41.

[0022] Furthermore, the conveying cylinder 3 is connected to the silo 1 through the feed pipe 33. The inside of the feed silo 31 is hollow. The spiral auger 32 is connected to the conveying cylinder 3 by a motor on the conveying cylinder 3. The spiral auger 32 acts below the feed silo 31 through the conveying cylinder 3. Through the connection between the conveying cylinder 3 and the feed silo 31, and the passage connection between the feed pipe 33 and the conveying cylinder 3, the rotation of the spiral auger 32 achieves the conveying effect of the slurry, which facilitates the filling operation in the silo 1.

[0023] Working principle: When filling and replenishing the slurry in the silo 1, the slurry enters the conveying cylinder 3 through the feed hopper 31. Under the rotation of the screw conveyor 32, the slurry is conveyed and enters the silo 1 through the feed pipe 33. With the connection of the stirring motor 21 and the stirring rod 22, and with the use of the stirring rod 22 and the retaining ring 4, the falling speed of the slurry is slowed down, so that it is fully mixed and achieves the effect of replenishing and filling at the same time.
