Description

Technical Field

[0001] The present application relates to the technical field of mortar residual material recovery devices, and specifically discloses a residual material recovery device for mortar. Background Art

[0002] Mortar is the bonding material used for bricklaying in construction. It is made of a certain proportion of sand and binder (cement, lime paste, clay, etc.) and water. Among them, the binder is Boake cement, lime paste, clay, etc.

[0003] According to the application form, mortar can be divided into two categories: premixed mortar (commercial mortar) and on-site mixed mortar; the cementitious materials used can be divided into cement, gypsum, lime, water glass and phosphate.

[0004] For mortars that use quartz sand, gravel, etc. as aggregates, it is usually necessary to mix the aggregates, cementitious materials and additives in a certain proportion to make granular or powdered materials, and then bag them and transport them to the construction site for use. This is called premixed mortar.

[0005] In the prior art, ready-mixed mortar has a particularly wide range of applications and is used in large quantities. However, in actual use and during the actual mixing process on construction sites, residual material often scatters or falls during mixing or discharging. Therefore, residual material recovery devices are used for recovery, screening, and reuse. In the prior art, these devices typically only focus on dispersing agglomerated materials, separating the agglomerated materials into granular and powder forms, without screening the granular materials based on particle size.

[0006] Therefore, in view of this, the inventor provides a residual material recovery device for mortar to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problem that the traditional residual material recovery device only separates the agglomerated materials but does not further screen the separated materials according to the particle size.

[0008] In order to achieve the above-mentioned purpose, the basic scheme of the present utility model provides a residual material recovery device for mortar, including a frame, a conveying assembly arranged in the frame, a driving structure arranged on the frame for driving the conveying assembly, a feeding frame arranged on the frame for feeding residual material to the conveying assembly, a discharging frame arranged on the frame and connected with the conveying assembly and used for discharging large particles of material, and a secondary screening assembly arranged in the frame. The frame is also provided with a fine material outlet connected to the secondary screening assembly. The conveying assembly is located at one end of the discharging frame at a height higher than that of one end of the feeding frame. The conveying assembly includes a conveying structure and a screening structure. The secondary screening assembly is arranged below the screening structure and is provided with a plurality of screening layers arranged in sequence. The frame is also provided with a main vibration mechanism for vibrating the conveying assembly and an auxiliary vibration mechanism for vibrating the secondary screening assembly.

[0009] Furthermore, the conveying structure includes a main shaft rotatably connected to one end of the frame and driven by the driving structure, a secondary shaft rotatably connected to the other end of the frame, pulleys coaxially fixed to the rotating shaft and the secondary shaft respectively, and a conveying belt meshed between the pulleys at both ends, and the screening structure is arranged on the conveying belt.

[0010] Furthermore, the screening structure includes a plurality of blanking troughs opened on the conveyor belt, and the conveyor belt between adjacent blanking troughs is equidistantly formed with connecting rods and inclined connecting plates fixedly connected thereto, and adjacent connecting rods are fixedly connected with screens connected to the conveyor belt on both sides.

[0011] Furthermore, a number of active shifting blocks are fixedly connected at equal distances to the bottom of both sides of the conveyor belt, and the active vibration mechanism includes a main vibrating plate fixedly connected to the inner walls of both sides of the frame, and the main vibrating plate is fixedly connected to a first driven shifting block that engages with the active shifting block at equal distances.

[0012] Furthermore, the inner walls on both sides of the frame are respectively fixed with pressure plates, which are respectively located above the two ends of the conveyor belt in the same plane, and the pressure plates are also in the same plane.

[0013] Furthermore, the auxiliary vibration mechanism includes auxiliary vibrating plates fixed to the inner walls on both sides of the frame and respectively located on the inner sides of the clamping plates, support rods fixed to the auxiliary vibrating plates, reciprocating sleeves slidably connected to the support rods and used to support the secondary screening assembly, and a second driven block fixed to the top of the reciprocating sleeve and engaged with the active block, and a return spring fixed to the support rods for ejecting the second driven block outward.

[0014] Furthermore, a first abutment plate is fixedly connected to the support rod, a reset spring is arranged between the first abutment plate and the second driven shifter, a sleeve plate is provided at the bottom end of the reciprocating sleeve, and a second abutment plate that can abut against the sleeve plate is fixedly connected to the support rod.

[0015] The principle and effect of this solution are:

[0016] 1. Compared with the prior art, the present invention, after separating the agglomerated materials, delivers the separated materials of the same type to the feed frame, and the materials fall from the feed frame into the conveying assembly, and are transmitted through the conveying structure of the conveying assembly, and are screened through the screening structure. The screened small-particle materials fall into the secondary screening assembly below for secondary screening to obtain materials of different particle size specifications, which solves the problem that the traditional residual material recovery device only separates the agglomerated materials but does not further screen the separated materials according to particle size.

[0017] 2. Compared with the prior art, the utility model is provided with a plurality of blanking troughs on the conveyor belt and the material is screened for the first time through the screen installed in the blanking trough. When the conveyor belt is moving, the active shift block at the bottom is engaged with the first driven shift block on the main vibrating plate fixed below in the frame to drive the conveyor belt to shake, thereby realizing the shaking of the screen and the screening of the material stored on the screen.

[0018] 3. Compared with the prior art, the present invention further has a secondary vibration mechanism fixedly installed in the frame, and the secondary vibration mechanism is correspondingly installed on the inner side of the clamping plate. During the movement of the conveyor belt, the active shift block at the bottom end is engaged with the second driven shift block, and the conveyor belt and the active shift block are fixed in the plane by the clamping plate. Therefore, during the engagement of the active shift block and the second driven shift block, only the second driven shift block and the reciprocating sleeve can slide toward the inner side of the support rod, and are subsequently reset by the reset spring. During the continuous movement of the conveyor belt, the reciprocating sleeve is realized by this meshing relationship, thereby achieving the purpose of vibrating the secondary screening component installed between the reciprocating sleeves.
