Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water-washed sand production equipment, and in particular relates to a stone crushing transfer bin with a grading function. Background Art
[0002] Washed sand is actually machine-made sand, which is what we usually call artificial sand. It is made by crushing large stones once, crushing them twice, screening them, and then sending them to the sand making machine for crushing. After screening, fine sand is obtained. These fine sands are washed away by sand washing machines to remove the stone powder and dust on the sand, and then become the sand used in our construction. In the processing of raw material stones, a transfer warehouse is often set up to store the transported stones so that the stones can be crushed, graded, crushed and made into sand. The raw stones contain some sizes that meet the size requirements after primary and secondary crushing. In order to improve the crushing efficiency and reduce energy consumption, some sand making plants will grade the stones coming out of the transfer warehouse before crushing them. The transfer warehouse in the prior art is built in a foundation pit below the ground for the convenience of material storage. Due to the lack of a structure for grading the raw stones, the gravitational potential energy of the raw materials is not utilized during storage. In the later stage, a grading device is set up, which consumes a lot of energy and is costly. Summary of the invention
[0003] In order to overcome the problems in the background technology, the utility model provides a stone crushing transfer bin with a grading function. After the truck unloads, some materials enter the storage bin through the unloading grille, and those that cannot enter directly are pushed onto the unloading grille by a push loader. When larger materials cannot be unloaded smoothly, they are crushed by a breaking hammer. The materials fall onto the grading device under the action of gravity potential energy, slide down along the grading device for grading, and are stored in each storage bin respectively. The potential energy of material unloading is reasonably utilized to complete material grading, avoiding material lifting and grading in the later stage, reducing energy consumption and saving costs.
[0004] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a stone crushing transfer bin with a grading function mainly includes a storage bin 1, a feeding grid 2, and a grading device 3, the storage bin 1 is arranged in a foundation pit, the storage bin 1 has a bin opening flush with the ground 10, a crossbeam is installed above one corner of the storage bin 1 opening to form a feeding opening, the feeding grid 2 is installed in the feeding opening, the grading device 3 is obliquely installed in the storage bin 1, the front end of the grading device 3 is below the feeding grid 2, the grading device 3 is respectively a first grading section 31 and a second grading section 32 along the sliding direction of the material, the size of the materials selected by the first grading section 31 and the second grading section 32 meet the size requirements after primary crushing and secondary crushing, and the storage bin 1 is sequentially divided into a secondary material storage bin 11, a primary material storage bin 12, and a raw stone material storage bin 13 corresponding to the grading device 3 along the grading direction of the grading device 3.

[0008] Furthermore, the secondary material storage bin 11, the primary material storage bin 12 and the raw stone material storage bin 13 are designed with conical bottoms for the convenience of discharging.
