Specific implementation mode

[0018] 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 in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3 , the embodiments provided by the present utility model:

[0020] A sand and gravel batching device for backfilling a soft foundation foundation pit includes a batching tank 1. A feed inlet 2 is provided on one side of the upper part of the batching tank 1, and a discharge outlet 3 is provided on one side of the lower part of the batching tank 1. A first reserved pipeline 5 is provided at the top of the batching tank 1, and a second reserved pipeline 6 is provided at the bottom of the batching tank 1. The provision of reserved pipelines facilitates the execution of other tasks, such as adding cleaning liquid to clean the inside of the batching tank 1 when it is idle, or introducing other materials for assisting batching. A discharge valve 4 is assembled on the bottom surface of the batching tank 1 on one side of the discharge outlet 3.

[0021] Batching components are symmetrically installed on the inner wall of the batching tank 1. The batching components include a connecting shaft 9, a first connecting rod 10, a first stirring rod 11, a second connecting rod 12, a second stirring rod 13, and a stirring blade 14. The two connecting shafts 9 are inserted between the inner walls of the batching tank 1 through bearing cooperation. The surfaces of the two connecting shafts 9 are welded to the first connecting rod 10 and the second connecting rod 12. The end of the first connecting rod 10 is welded with a first stirring rod 11, and the end of the second connecting rod 12 is welded with a second stirring rod 13. An installation groove 15 is provided on the surface of the connecting shaft 9, and a stirring blade 14 is assembled in the installation groove 15. The end of one of the connecting shafts 9 passes through the surface of the batching tank 1 and is in transmission connection with the output end of the drive motor 8 through a coupling. The drive motor 8 is bolted to the surface of the batching tank 1 through the installation frame 7 and a connecting piece.

[0022] One end of the stirring blade 14 is provided with an insertion sheath. Slots are sequentially and evenly formed on the surface of the connecting shaft 9 at the installation groove 15. The stirring blade 14 is fixedly inserted into the slots through the cooperation of the insertion sheath. With the cooperation of this structure, it is convenient to disassemble and assemble the stirring blade 14 at any time, and the number of stirring blades 14 can be increased at any time according to requirements, thereby improving the mixing strength.

[0023] The first connecting rod 10, the second connecting rod 12, the first stirring rod 11 and the second stirring rod 13 are all integrated structures made of steel structure materials. They have good strength and stiffness, can ensure the overall processing effect, avoid damage or even fracture of each part structure during continuous batching, and can effectively ensure the overall service life. Both connecting shafts 9 pass through the surface of the batching tank 1 and are installed with transmission wheels through keys. The two transmission wheels are connected by a transmission belt 16 for transmission cooperation. It plays a role in transmission and driving. When the equipment starts to operate, the sand and gravel materials to be batched are sent into the batching tank 1 through the feed port 2. At this time, the feed port 2 is closed, and the connecting shaft 9 is rotated by the driving motor 8 to rotate inside the batching tank 1 for batching operations. The connecting shafts 9 perform transmission rotation through the cooperation of the transmission belt 16 and the transmission wheels. The two batching mechanisms rotate respectively to fully mix the sand and gravel materials inside the batching tank 1. The stirring blade 14 is used to turn the materials, and during this period, the first stirring rod 11 and the second stirring rod 13 break up the possible lumps in the sand and gravel to avoid poor mixing effects. After completion, it can be discharged by opening the discharge port 3, and the discharge valve 4 is used to discharge the residual materials.
