Description

Technical Field

[0001] The utility model belongs to the technical field of dry-mix mortar production, in particular to a dry-mix mortar material proportioning and feeding device. Background Art

[0002] Dry-mixed mortar is a pre-mixed building material, which is a granular or powdered substance formed by physically mixing dry and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) in a certain proportion. When in use, it can be used directly by simply adding water and mixing on the construction site, so it is also called mortar dry powder or dry mix powder. Dry-mixed mortar is widely used in the construction industry in masonry, plastering, flooring, decoration, putty and other projects. It can provide bonding, padding, protection and decoration functions. In the production process of dry-mixed mortar, in order to determine the components of the mortar, it is necessary to proportion and feed the materials, but it still has the following disadvantages in actual use:

[0003] In the process of proportioning dry-mixed mortar materials, the operator needs to first transport a component raw material to the weighing structure through the feeding structure, weigh the specified weight in the weighing structure, and then transport it to the mixing container. Repeat this process before mixing the materials. It takes a long time to work and the operation is not convenient.

[0004] When the dry-mixed mortar materials are proportioned and fed into the mixing equipment, a single raw material is directly fed into the mixing equipment. During the feeding process, the feeding needs to be done step by step. Mixing during the feeding process will cause dust leakage. Waiting for the feeding to be completed before mixing will result in a longer working cycle. Utility Model Content

[0005] The purpose of the utility model is to provide a dry-mix mortar material proportioning feeding device, which solves the problem that the process of proportioning dry-mix mortar materials takes a long time and cannot achieve both a short cycle and reduce pollution by arranging an upper bin, a weighing component and a lower bin.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] Furthermore, partitions are fixed between adjacent piston rods on the inner wall of the upper silo, and a discharge hopper is fixed on the inner wall of the upper silo below each hydraulic cylinder. Adjacent discharge hoppers are fixed on both sides of the same partition. Partitions are used to separate spaces for accommodating different materials in the upper silo, and different raw materials of the slurry are centrally transported to the output shell through the discharge hopper.

[0009] Furthermore, the bottom of each of the discharge hoppers is fixedly connected to an output shell, the plug block is movably connected to the bottom end of the output shell, and the material in the discharge hopper is output to the lower silo through the output shell.

[0010] Furthermore, support feet are symmetrically fixed at the lower edges of the front and rear sides of the upper silo, and the support feet are fixed at the upper edges of the front and rear sides of the lower silo. The upper silo and the lower silo are supported on the working platform by the support feet.

[0011] Furthermore, the weighing assembly also includes an electronic scale and a fixed plate. The fixed plate is fixed to the bottom of the inclined platform. The electronic scale is symmetrically fixed to the bottom of the fixed plate along a center line parallel to the short side. The weighing assembly weighs the material falling onto the inclined platform through the electronic scale.

[0012] Furthermore, a movable opening is provided on one side of the lower material bin close to the lower end of the inclined platform, the bottom of the movable opening is lower than the lower end edge of the top of the inclined platform, and the lower material bin discharges the material through the movable opening.

[0014] The utility model has the following beneficial effects:

[0015] The utility model solves the problem that the process of proportioning dry-mixed mortar materials takes a long time by arranging an upper bin, a weighing component and a lower bin. When the weight ratio of different materials is determined, the hydraulic cylinder at the corresponding position is started, and the hydraulic cylinder drives the piston rod to drive the plug to descend, so that the bottom of the output shell at the corresponding position is opened, and the materials separated by the partition in the upper bin enter the discharge hopper and are centrally transported to the lower bin. The reading on the electronic scale is observed until the reading increases by a specified weight, and the hydraulic cylinder at this position is restarted to drive the piston rod to drive the plug to re-close the bottom of the output shell. After repeating the above-mentioned feeding operation for different raw materials, the material proportioning operation is completed, making the material proportioning more convenient and rapid.

[0016] The utility model solves the problem of both short cycle and low pollution by arranging a weighing component and a feeding bin.

Therefore, during work, the feeding of the proportioned materials is more concentrated, reducing dust dispersion. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0026] See also Figure 1-5 The utility model is a dry-mix mortar material proportioning feeding device, comprising an upper bin 1, a weighing assembly 2 and a lower bin 3. A plurality of support plates 104 are equidistantly fixed on the upper inner wall of the upper bin 1. The upper bin 1 accommodates the materials to be transported during proportioning. The hydraulic cylinder 105 is fixedly supported above the upper bin 1 through the support plates 104. A hydraulic cylinder 105 is fixed on the top of each support plate 104. A piston rod 106 is movably connected in the hydraulic cylinder 105. The piston rod 106 is movably connected in the support plate 104. A plug 107 is fixed at the bottom end of the piston rod 106. When working, the piston rod 106 is driven to descend by the hydraulic cylinder 105, driving the plug 107 to descend. The bottom end of the output shell 103 is opened to transport the corresponding raw materials to the lower material bin 3. When the hydraulic cylinder 105 drives the piston rod 106 to rise, it drives the plug 107 to close the bottom end of the output shell 103 and stop the transportation of the corresponding materials. The lower material bin 3 is fixed at the bottom of the upper material bin 1. The lower material bin 3 cooperates with the weighing component 2 to accommodate the materials falling into it during the proportioning. The weighing component 2 is movably connected to the lower part of the inner wall of the lower material bin 3. The weighing component 2 includes an inclined platform 203, which is arranged to be through-connected from front to back. The inclined platform 203 is movably connected to the lower part of the lower material bin 3, and the materials are supported by the inclined platform 203. After weighing and proportioning, the materials are output to the movable port 301.

[0027] Specifically, partitions 108 are fixed between adjacent piston rods 106 on the inner wall of the upper bin 1, and a discharge hopper 102 is fixed on the inner wall of the upper bin 1 below each hydraulic cylinder 105. Adjacent discharge hoppers 102 are fixed on both sides of the same partition 108. The upper bin 1 separates different materials through the partition 108, and the materials separated by the partition 108 in the upper bin 1 are centrally transported to the output shell 103 through the discharge hopper 102.

[0028] Furthermore, the bottom of each discharge hopper 102 is fixedly connected to an output shell 103, and a plug 107 is movably connected to the bottom end of the output shell 103. When the plug 107 leaves the discharge shell, the material is discharged from the output shell 103. When the plug 107 is pressed to the bottom end of the output shell 103, the bottom end of the output shell 103 is plugged and sealed.

[0029] Furthermore, support feet 101 are symmetrically fixed at the lower edges of the front and rear sides of the upper material bin 1, and the support feet 101 are fixed at the upper edges of the front and rear sides of the lower material bin 3. The upper material bin 1 and the lower material bin 3 are supported on the working platform by the support feet 101.

[0030] Furthermore, the weighing assembly 2 also includes an electronic scale 201 and a fixed plate 202. The fixed plate 202 is fixed to the bottom of the inclined platform 203. The electronic scale 201 is symmetrically fixed to the bottom of the fixed plate 202 along a center line parallel to the short side. When the material falls onto the inclined platform 203, the downward weight is transferred to the electronic scale 201, and the weight of the material is weighed by the electronic scale 201.

[0031] The operation process of this embodiment is as follows: when working, first, different materials are poured into the separated storage space in the upper silo 1 through the gap between the partition 108 and the support plate 104, and then the materials can be proportioned. When the weight ratio of different materials is determined, the hydraulic cylinder 105 at the corresponding position is started, and the hydraulic cylinder 105 drives the piston rod 106 to drive the plug 107 to descend, so that the bottom of the output shell 103 at the corresponding position is opened, and the materials separated by the partition 108 in the upper silo 1 enter the discharge hopper 102 and are centrally transported to the lower silo 3. The reading on the electronic scale 201 is observed until the reading increases to a specified weight, and then the hydraulic cylinder 105 at this position is restarted, and the piston rod 106 is driven to drive the plug 107 to re-seal the bottom of the output shell 103. After repeating the above-mentioned feeding operation for different raw materials, the material proportioning operation is completed. Specific embodiment 2

[0032] See also Figure 1 , 5 On the basis of the specific embodiment 1, a movable opening 301 is opened on one side of the lower end of the inclined platform 203 of the lower material bin 3, and the bottom of the movable opening 301 is lower than the lower end edge of the top of the inclined platform 203. When the lower material bin 3 is working, the position of the movable opening 301 is aligned with the mortar mixing equipment. During operation, the material on the inclined platform 203 is transported to the mortar mixing equipment through the movable opening 301 after the closing latch 4 is opened.

[0033] Specifically, limiting angle irons 302 are fixed at the edges of the discharge bin 3 in front and behind the movable opening 301. The two limiting angle irons 302 are symmetrical to each other. A closing latch 4 is movably connected to the two limiting angle irons 302. The closing latch 4 is movably connected thereto through the limiting angle irons 302. The material is sealed in the discharge bin 3 through the closing latch 4. When the material is mixed, the closing latch 4 is removed and the material can be discharged into the mixing equipment through the movable opening 301.

[0034] The operation process of this embodiment is as follows: during work, after the materials are proportioned, the closing latch 4 is removed, and after the closing latch 4 is opened, the materials on the inclined platform 203 are transported to the mortar mixing equipment through the movable port 301. After all the materials on the inclined platform 203 are poured out, the latch is aligned with the two limiting angle irons 302, and the closing latch 4 is reset to complete the feeding of the materials after proportioning, so that when working, it is more convenient to feed the materials after proportioning.
