Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a slurry mixing equipment for preparing slurry soil as shown in Figure 1-6 and includes:

[0026] A mixing device 1, a discharge pipe 2, a driving device 3 and a feeding mechanism. The driving device 3 is arranged on the front of the mixing device 1, and the driving device 3 is used to provide power for the mixing device 1. The discharge pipe 2 is arranged at the bottom of the mixing device 1, and the feeding mechanism is arranged at the top of the mixing device 1;

[0027] The feeding mechanism includes a feeding component 4 and a screening component 5. The screening component 5 includes a screening net 51. The feeding component 4 includes a feeding pipe 41. The screening net 51 is arranged inside the feeding pipe 41. A driving member 8 for vibrating the screening net 51 is arranged at the bottom of the screening net 51, and a pushing component 6 for pushing the screening component 5 is arranged at the top of the screening component 5.

[0028] Specifically, an installation plate 42 for connecting with the top of the mixing device 1 is sleeved on the outer wall of the bottom of the feeding pipe 41.

[0029] Furthermore, the mixing device 1, the discharge pipe 2 and the driving device 3 form an existing soil double-shaft mixer. In the horizontal cylinder of the soil double-shaft mixer, there are paddle blades rotating in opposite directions on the double shafts. The paddle blades are at a certain angle to circulate and stir the materials axially and radially, so that the materials are quickly and evenly mixed. The feeding pipe 41 and the installation plate 42 are fixed by welding, and the installation plate 42 is fixedly connected with the top of the mixing device 1 by bolts.

[0030] Specifically, an installation frame 52 for installing the screening net 51 is sleeved on the outer wall of the screening net 51. An impact plate 7 for impacting the installation frame 52 is arranged at the bottom of the installation frame 52. The driving member 8 is arranged at the bottom of the impact plate 7. The driving member 8 includes an electric cylinder 81. The output end of the electric cylinder 81 is fixedly connected with a connecting plate 82 for connecting with the impact plate 7. The bottom of the electric cylinder 81 is fixedly connected with a fixing plate 10 for installing the electric cylinder 81. One side of the fixing plate 10 is fixedly connected with one side of the inner wall of the feeding pipe 41, and a protective cover 9 for protecting the electric cylinder 81 is arranged at the top of the fixing plate 10.

[0031] Furthermore, the outer wall of the screening mesh 51 is fixedly connected to the inner wall of the mounting frame 52 by bonding. The aperture of the screening mesh 51 is 3 cm. Two impact plates 7 are provided, symmetrically arranged on both sides of the bottom end of the mounting frame 52. The impact plates 7 are made of hard plastic plates. The length of the impact plates 7 corresponds to the width of the mounting frame 52. Two driving members 8 are provided, respectively arranged at the bottom ends of the impact plates 7. The connecting plate 82 is fixedly connected to the bottom end of the impact plate 7 by bolts. The fixing plate 10 is fixedly connected to the inner wall of the feed pipe 41 by welding. The bottom end of the electric cylinder 81 is connected to the top end of the fixing plate 10 by bolts. Two protective covers 9 are sleeved on the outer wall of each electric cylinder 81. A semi-circular groove is opened at the top end of the protective cover 9 for the output end of the electric cylinder 81 to extend out. A fixing foot is welded on the outer wall of the protective cover 9. A round hole is opened at the top end of the fixing foot. A bolt is inserted through the round hole to fix the protective cover 9 to the top end of the fixing plate 10. The protective cover 9 is made of steel material to protect the electric cylinder 81. When the output end of the electric cylinder 81 contracts to the shortest, the top end of the impact plate 7 does not contact the mounting frame 52. When the electric cylinder 81 works, the output end of the electric cylinder 81 quickly retracts back and forth, driving the impact plate 7 to impact the bottom end of the mounting frame 52. The symmetrically arranged electric cylinders 81 are started simultaneously. Due to the different impact speeds of the electric cylinders 81, the two ends of the mounting frame 52 fluctuate differently, quickly filtering the soil taken at the top of the screening mesh 51.

[0032] Specifically, the pushing component 6 includes a compression spring 61. The bottom end of the compression spring 61 is fixedly connected to the top end of the mounting frame 52. The top end of the compression spring 61 is fixedly connected to a mounting frame 62 for mounting the compression spring 61. One side of the mounting frame 62 is fixedly connected to one side of the inner wall of the feed pipe 41. The top end of the mounting frame 62 is fixedly connected to a block 63 for protecting the mounting frame 62.

[0033] Further, a plurality of extrusion springs 61 are provided. The plurality of extrusion springs 61 are arranged in two rows and symmetrically arranged on both sides of the top end of the mounting frame 52 respectively. The top end and the bottom end of the extrusion spring 61 are fixedly connected to the bottom end of the mounting bracket 62 and the top end of the mounting frame 52 respectively by welding. One side of the mounting bracket 62 is fixedly connected to the inner wall of the feed pipe 41 by bolts. When the impact plate 7 impacts the mounting frame 52, the mounting frame 52 moves towards the mounting bracket 62, squeezing the extrusion spring 61. The restoring force of the extrusion spring 61 will push the mounting frame 52 towards the electric cylinder 81, so that the mounting frame 52 falls rapidly. With the impact of the impact plate 7 again, the mounting frame 52 rises again. In this way, the vibration speed of the mounting frame 52 can be increased, further improving the filtering effect. The stop block 63 is made of elastic rubber material. The side of the stop block 63 away from the inner wall of the feed pipe 41 is arc-shaped. Thus, when a hard object falls into the stop block 63, the stop block 63 will produce elastic deformation and eject the hard object, thereby protecting the mounting bracket 62 and preventing the mounting bracket 62 from being smashed and deformed.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
