DETAILED DESCRIPTION

[0024] 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.

[0025] Example 1: As Figures 1-3 The technical solution shown is a grouting device for iron ore filling. In order to solve the problem of inconvenient carrying and transportation of the grouting device, the following are disclosed: a movable base 1 and a cooling chamber 2 set at the upper end of the movable base 1, and a mixing chamber 3 set at the upper end of the cooling chamber 2. A grouting pipe 5 is connected to the right side of the mixing chamber 3, and a filter plate 4 is fixedly installed on the inner wall of the mixing chamber 3. Four universal wheels are set at the bottom of the movable base 1, and the cooling chamber 2 and the mixing chamber 3 are connected. A pressure pump 6 is set at the middle end of the grouting pipe 5, and the left side of the pressure pump 6 is fixedly installed on the right outer wall of the cooling chamber 2. The upper left end of the grouting pipe 5 is located at the upper end of the filter plate 4.

[0026] Four casters are provided at the lower end of the mobile base 1. During use, the device can be moved easily by the casters. At the same time, after adding slurry through the opening at the upper end of the mixing chamber 3, it will accumulate on the filter plate 4 inside. By starting the pressure pump 6, grouting is carried out under the action of the grouting pipe 5. This allows for convenient operation of grouting and is easy for users to use.

[0027] Example 2: Figures 1-4 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of slurry solidification caused by high temperatures: a drive motor 7 is provided at the upper end of the mixing chamber 3, and a cooling and anti-solidification mechanism is provided at the output end of the drive motor 7. The cooling and anti-solidification mechanism is provided with a stirring rod 8, and the upper end of the stirring rod 8 is provided at the output end of the drive motor 7. The stirring rod 8 of the cooling and anti-solidification mechanism is rotatably connected to the mixing chamber 3, and the stirring rod 8 is rotatably connected to the middle end of the filter plate 4. A condenser 9 is provided at the bottom of the grouting pipe 5, and the rear end of the cooling chamber 2 is connected to the bottom of the guide pipe 10. The upper end of the guide pipe 10 is installed through the rear end of the mixing chamber 3, and a water pump 11 is provided at the middle end of the guide pipe 10. The front end of the water pump 11 is fixedly installed at the rear end of the grouting pipe 5.

[0028] When the slurry falls onto the filter plate 4, the drive motor 7 is started, and the output end of the drive motor 7 drives the stirring rod 8 to rotate. The rotation of the stirring rod 8 can stir and mix the slurry on the filter plate 4, and at the same time, the water inside is filtered, so that the water falls into the surface of the condenser 9 inside the cooling chamber 2. At the same time, cold water can also be added through the opening at the top of the mixing chamber 3. When it falls into the surface of the condenser 9 inside the cooling chamber 2, it is cooled by the condenser 9 and then pumped into the mixing chamber 3 through the guide pipe 10 under the action of the water pump 11, and water is added again for mixing. This can keep the temperature of the slurry low, prevent high temperature solidification, and ensure the efficiency of the device.

[0029] Example 3: Figures 1-6 The technical solution shown, based on Embodiment 2, discloses the following to solve the blockage problem inside the device: a rotating rod 13 is rotatably arranged on the left side of the mixing chamber 3, and a vibration anti-blockage mechanism is provided at the lower end of the rotating rod 13. The vibration anti-blockage mechanism is provided with a conveyor belt 12, and the conveyor belt 12 is nested in the upper end of the stirring rod 8 and the rotating rod 13 under the action of the pulley. The vibration anti-blockage mechanism is provided with a fixing plate 15, and the right side of the fixing plate 15 is fixedly installed on the left outer wall of the mixing chamber 3. A striking plate 16 is provided on the inner side of the fixing plate 15, and limit blocks 17 are fixedly installed at the front and rear ends of the striking plate 16. The surface of the limit block 17 is slidably connected to the fixing plate 15.

The outer side of the striking plate 16 corresponds to the position of the cam 14, and the upper end of the cam 14 is fixedly installed at the lower end of the rotating rod 13.

[0030] When the stirring rod 8 rotates, the stirring rod 8 drives the rotating rod 13 to rotate via the conveyor belt 12. The rotating rod 13 rotates under the limit of the limiting sleeve. As the rotating rod 13 rotates, the cam 14 at its bottom rotates and squeezes the striking plate 16. When the striking plate 16 is squeezed, it slides along the opening inside the fixed plate 15 through the limiting block 17, thereby knocking the mixing chamber 3 to achieve the effect of knocking and preventing blockage. Under the action of the vibration spring 18, the frequency of the back-and-forth movement of the striking plate 16 can be increased to ensure the efficiency of knocking.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
