[0017] Please see Figure 1-3As shown, this application provides a technical solution: a hydroseeding machine for mine ecological restoration, including a trolley 11, a slurry tank 12 disposed above the trolley 11, a hydroseeding pump 13 and a spray gun 14. One side of the hydroseeding pump 13 is connected to the slurry tank 12, and the other side is connected to the spray gun 14. An inlet 121 is also provided above the slurry tank 12. A detachable stirring mechanism 2 is provided above the inlet 121. A pipe 15 is provided between the inlet 121 and the outlet of the stirring mechanism 2. A switch door structure 3 is provided outside the pipe 15. The switch door structure 3 includes a switch door 31, which is inserted into the pipe 15 to close the pipe 15.

[0018] In this way, the spray pump 13 can draw material from the slurry tank 12 and spray it onto the mine through the spray gun 14. The door opening and closing structure 3 can be directly set above the slurry tank 12, which is easy to install, and then the mixing mechanism 2 is installed.

[0019] In a preferred embodiment, the door opening and closing structure 3 further includes a mounting base 32 disposed on the slurry tank 12, an electric actuator 33 disposed on the mounting base 32, and the door opening and closing 31 disposed on the extension shaft of the electric actuator 33.

[0020] When it is necessary to close the bottom of the mixing mechanism 2, the electric push rod 33 extends out of the switch door 31 to block the material passage inside the pipe 15. At this time, the material inside the mixing mechanism 2 cannot descend into the slurry tank 12. When the mixing mechanism 2 needs to release the material, the electric push rod 33 retracts and drives the switch door 31 to retract, thereby opening the material discharge passage of the mixing mechanism 2.

[0021] In a preferred embodiment, the stirring mechanism 2 includes a stirring box 22 connected to the slurry tank 12 by screws 21, a rotating shaft 23 located in the middle of the stirring box 22, a stirring rod 24 located on the rotating shaft 23, and a stirring blade 25 located on the stirring rod 24; the lower end of the stirring box 22 is an arc-shaped plate 26 that matches the stirring blade 25, and the discharge port of the stirring mechanism 2 is located on the arc-shaped plate 26.

[0022] In a preferred embodiment, a spraying mechanism 4 is also provided inside the mixing tank 22. The spraying mechanism 4 includes a water injection pipe 41, which is fixed to the upper part of the mixing tank 22. The rear end of the water injection pipe 41 passes through the mixing tank 22 and is fixedly connected to a flange 42. A nozzle 43 is fixedly connected to the upper part of the water injection pipe 41.

[0023] Flange 42 can be connected to an external water pipe, and water can be sprayed into the mixing tank 22 through nozzle 43.

[0024] In a preferred embodiment, a soil vibrating screen 5 is provided at the upper end of the mixing tank 22. The soil vibrating screen 5 includes an inclined frame 51, which is fixed to the upper part of the mixing tank 22. Springs 52 are fixedly connected to the four corners of the upper surface of the inclined frame 51. A bracket 53 is fixedly connected to the upper end of the four springs 52. A screen 54 is fixedly connected to the upper surface of the bracket 53. A motor 55 is fixedly installed on the lower surface of the bracket 53. An eccentric wheel 56 is fixedly connected to the output end of the motor 55.

[0025] In this way, soil of a certain diameter is screened by the soil vibrating screen 5, which facilitates mixing by the mixing mechanism 2.

[0026] In a preferred embodiment, rollers 16 are provided below the trolley 11.

[0027] The working principle of this equipment is as follows: when the motor 55 is turned on, the motor 55 drives the eccentric wheel 56 to rotate, causing the bracket 53 and the screen 54 to vibrate. The soil is slowly poured onto the screen 54 by an external loader, and the soil can be screened. The qualified soil falls into the mixing tank 22. When the specified amount of soil is reached, the soil screening is stopped, and a certain amount of grass seeds, water-retaining agent, adhesive and other raw materials are poured into the mixing tank 22. The mixing rod 24 and the mixing plate 25 are driven to rotate by the rotating shaft 23 to mix. At the same time, appropriate water is injected through the spraying mechanism 4. After the mixing is completed, the door opening structure (3) opens the door 31, and the slurry flows into the slurry tank 12. Spraying can be carried out by the spraying pump 13 and the spray gun 14. This soil spraying equipment has multiple functions such as soil screening, slurry mixing, slurry storage and spraying. When spraying, there is no need to equip a soil screening machine and a mixing machine, which reduces the overall cost of the spraying system, facilitates transportation, and greatly improves the practicality of the soil spraying machine.

[0028] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
