Description

Technical Field

[0001] The utility model relates to the technical field of mortar mixing, in particular to a feeding device for dry-mixed mortar mixing. Background Art

[0002] Dry-mix mortar plays a bonding, lining, protection and decorative role in the construction industry with a thin layer. It is widely used in infrastructure construction around the world in construction and decoration projects and road construction, so dry-mix mortar stirring devices are used;

[0003] After searching, it was found that the Chinese patent with application number 202021699431.9 discloses a dry-mix mortar stirring device with quantitative feeding. The sliding rod is pushed by the connecting block to make the second baffle slide, thereby controlling the falling of the material, and there is also a first baffle below to prevent the material in the feed box from falling into the barrel due to insufficient dosage, and the specifications of the quantitative block can be replaced, which is convenient for adjusting the quantity; the position of the second baffle is adjusted by the connecting block. When there is no material in the feed box, the second motor will drive the rotating rod, and the rotating rod will make the connecting block slide, thereby driving the second baffle back to the outside of the feed box to ensure continuous feeding; when the material enters the barrel, it is first pre-mixed by the mixing rod, and then falls to the bottom of the barrel. The pre-mixing and stirring at the bottom of the barrel will save some time, thereby making the mixing efficiency higher.

[0004] Regarding the above technology, the inventor believes that since the mortar raw materials will inevitably become damp and hardened into lumps during storage, the hardened mortar raw materials cannot be used normally. Although they are mixed with qualified mortar raw materials, the pasted materials will be loose and easy to fall off when the building materials are pasted, thereby affecting the construction quality.
