Description

TECHNICAL FIELD

[0001] The utility model relates to mortar processing technical field, more specifically, relate to a kind of mixing device for dry-mixed mortar production and processing. BACKGROUND

[0002] Dry-mixed mortar refers to fine aggregate and inorganic cementing material, water-retaining thickening material, mineral admixture and additive are physically mixed according to certain proportion to form a granular or powder, in the form of bag or bulk, to site, after mixing with water, it can be directly used material.

[0003] When using mortar mixing device to mix material, in addition to considering the internal mixing of mortar, it also needs to consider when adding raw materials, to avoid the screen blockage caused by adding a large amount of raw materials at once at the feed inlet, therefore, a screening device for mortar mixture production is provided in Chinese patent publication No. CN217289291U, under the elastic force of the elastic member, the receiving cylinder supports the top rod and the stop block, so that the stop block is located above the connecting pipe, at this time, the fixed cylinder is in an open state, so that the raw materials in the feeding box enter the receiving cylinder along the connecting pipe and the fixed cylinder, then, as the amount of raw materials in the receiving cylinder increases, the receiving cylinder descends under the action of gravity, and follows the descending sealing fixed cylinder, the fixed rod ejects the sealing ball out of the discharge slot, and the raw materials enter the screening box, then, as the amount of raw materials in the receiving cylinder decreases, they return to their original positions under the elastic force of the elastic member, forming a cycle of feeding, avoiding frequent manual feeding.

[0004] However, in actual use scenarios, during the rainy season, long-term storage of raw materials can cause sand and powder to be compressed for a long time, and combined with the humid storage environment, it is easy to cause the raw materials to be compacted and clumped, at this time, the clumped raw materials will accumulate and form a blockage at the connecting pipe of the feeding box, making it difficult to discharge, reducing production efficiency and quality. UTILITY MODEL CONTENTS

[0005] The utility model provides a kind of mixing device for dry-mixed mortar production and processing, which solves the problems raised in the above background technology by the inclination angle formed by the vibration screen mesh with different thicknesses falling into secondary tooth roller to crush mortar clumps, i.e.:

[0006] Long-term compression of raw materials and humid storage environment during the rainy season cause the raw materials to be clumped before mixing, forming a blockage at the connecting pipe of the feeding box, reducing work efficiency.

[0007] In order to achieve the above object, the mortar mixing device comprises a feeding mechanism, and a crushing mechanism and a vibrating device are arranged on one side of the feeding mechanism, the feeding mechanism comprises a side plate, and a vibrating screen is fixedly installed between the inner walls of the side plate; the vibrating screen forms an inclination in the side plate due to the different thicknesses of the two sides, and an inclined plate is fixedly installed in the notch opened in the position corresponding to the vibrating screen on one side of the side plate.

[0008] In the above technical solution, because the thicknesses of the two sides of the vibrating screen are different, the vibrating screen forms an inclination in the side plate, when the mortar raw materials enter the inside of the side plate, the fine powder mortar falls into the lower part through the plurality of screen holes opened in the vibrating screen, however, due to the mixing of water and mortar during daily storage, the formed lumps cannot fall through the screen holes, at this time, with the vibration of the vibrating screen, the mortar lumps slowly roll to the thinner side of the vibrating screen under the vibration, until the lumps roll to the edge and fall into the secondary tooth roller through the inclined plate for crushing, in addition, the inclined vibrating screen is more likely to make the powder mortar fall through the screen holes under the vibration, and the powder cannot be accumulated.

[0009] On this basis, the vibrating plates are fixedly installed on the two sides of the radial position of the inclined plate, the vibrator and the shock absorber are installed above and below the part of the vibrating plate located on the outside of the side plate, when the vibrator is turned on, the vibrating plate can drive the internal vibrating screen to vibrate, so that the mortar can smoothly fall from the screen holes when being above the vibrating screen, and the screen holes of the vibrating screen are prevented from being blocked due to powder accumulation.

[0010] In another technical solution, the notch provided at the connection position of the vibrating plate and the vibrating screen is fixedly installed with an elastic element, the elastic element limits the vibrating screen under the vibration, and the vibrating screen vibrates within the elastic range of the elastic element.

[0011] The mortar mixing device further comprises a secondary tooth roller which is rotationally connected to the shaft body through the shaft center of the gear set, and the secondary tooth roller is located on the side of the side plate close to the inclined plate, when the mortar lumps fall into the secondary tooth roller under the combined action of the inclination of the vibrating screen and the inclined plate, the crushing motor drives the two sets of secondary tooth rollers to rotate towards each other through the gear set, so that the mortar lumps falling on the surface of the secondary tooth roller are crushed to become powder, and then fall into the discharge port through the lower crushing screen.

[0012] Compared with the prior art, the mortar mixing device has the following beneficial effects:

[0013] Through the inclination angle formed by the vibrating screen sieve with different thickness, and because of the effect of the vibrator on the vibrating screen sieve, the internal caked raw materials roll to the inclined plate through the inclination angle, and fall into the secondary tooth roller for crushing, so that the caked raw materials formed due to the humid environment and pressure before entering the mixing device are crushed, and smoothly enter the mixing device, and the crushed raw materials can reduce the friction on the stirring blades during mixing, avoid excessive wear or deformation of the blades, improve the production efficiency, and also improve the quality of the subsequent mortar.
