Description

Technical Field

[0001] The present application relates to the technical field of elevators, and specifically discloses a batching elevator for premixed 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] The production process of ready-mixed mortar involves the selection and mixing of multiple ingredients. During the mixing process, the rated amount of ingredients needs to be placed in a storage frame, passed through the storage frame into the hopper of the elevator, and continuously fed by the elevator.

[0006] In the prior art, the amount of each ingredient used in the preparation of premixed mortar varies, and therefore, the continuous feeding process involves quantitative feeding of multiple different ingredients. However, in the prior art, the amount of material in each elevator hopper cannot be controlled during the feeding process using the elevator.

[0007] Therefore, in view of this, the inventor provides a batching elevator for ready-mixed mortar to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to solve the problem that the traditional batching elevator cannot measure the amount of materials in each funnel during the feeding process.

[0009] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a batching elevator for premixed mortar, including an inclined shell, a belt lifting mechanism arranged in the shell, a plurality of hoppers arranged in the shell and driven by the belt lifting mechanism, and a driving structure arranged on the shell for driving the belt lifting mechanism. A discharge port for discharging materials is opened on the inner side of the top of the shell, and a feeding pipe connected to the storage frame is connected to the top of the bottom end of the shell. A quantitative feeding structure is provided between the top of the feeding pipe and the storage frame. A transmission mechanism is provided between the quantitative feeding structure and the driving structure. The quantitative feeding structure includes a rotating shaft rotatably connected to the top of the feeding pipe and driven by the transmission mechanism, a disc coaxially fixed to the rotating shaft, and a plurality of accommodating chambers circumferentially opened on the disc. Stops are respectively fixed on both sides of the top of the feeding pipe, which are in contact with the outer wall of the disc. A gap is formed between the two stoppers for exposing the accommodating chamber. The disc is detachably connected to a plurality of partitions respectively extending into the accommodating chamber. When any accommodating chamber is connected to the interior of the shell, only the independent hopper is located at the bottom of the shell.

[0010] Furthermore, the cross-section of the accommodating chamber is rectangular, and adjacent accommodating chambers are not connected to each other.

[0011] Furthermore, the disc is provided with a number of slide grooves respectively connected to the accommodating chambers, and the inner walls on both sides of the slide grooves are respectively fixed with rubber pads that fit each other, and the partition is provided with studs that pass through the rubber pads on both sides of the slide groove and are slidably connected to the rubber pads on both sides, and the studs pass through a section of the rubber pad and are threadedly connected to a nut.

[0012] Furthermore, the stud is fixedly connected to the partition.

[0013] Furthermore, the stud is fixed to the side of the partition facing the bottom surface of the accommodating chamber.

[0014] Furthermore, a plurality of material-moving rods are equidistantly provided in the gap between the two side baffles.

[0015] Furthermore, the transmission mechanism is an intermittent motion mechanism driven by a driving structure.

[0016] The principle and effect of this solution are:

[0017] Compared with the prior art, the present invention is provided with a quantitative feeding structure on the top of the feeding pipe connected to the shell. When the belt lifting mechanism drives the hopper to move continuously, the rotation of the rotating shaft in the quantitative feeding structure drives the disc to rotate, and the material is stored when it is retained in the gap between the two side stops through the accommodating chamber in the disc. The amount of material stored in the accommodating chamber each time can be controlled by adjusting the installation position of the partition. The rotation of the rotating shaft drives the disc to rotate, and the ingredients stored in the accommodating chamber are put into the feeding pipe and discharged into the bottom end of the shell. The subsequent hopper loads and transports the ingredients discharged this time, and the next-level hopper loads and transports the ingredients when the ingredients are discharged next time, which solves the problem that the traditional ingredient elevator cannot measure the amount of material in each funnel during the loading process.

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0023] The figure marks in the drawings of the specification include: shell 1, storage frame 2, hopper 3, driving shaft 4, baffle 5, accommodating chamber 6, disc 7, feed pipe 8, material removal rod 9, ingredients 10, partition 11, stud 12, slide 13, rotating arm 14, and groove wheel 15.

[0024] A batching elevator for ready-mixed mortar, for example Figure 1 As shown:

[0025] It comprises a shell 1, a belt lifting mechanism installed in the shell 1, a plurality of hoppers 3 installed in the shell 1 and driven by the belt lifting mechanism, and a driving structure installed on the shell 1 and used to drive the belt lifting mechanism.

[0026] Specifically, the left end of the shell 1 is higher than the right end, a discharge port is provided on the inner side of the left end of the shell 1, and a feed port is provided on the top of the right end of the shell 1 and is connected to a feed pipe 8. The belt lifting mechanism includes a driven shaft rotatably mounted on the left end of the shell 1, a driving shaft 4 rotatably mounted on the right end of the shell 1, pulleys coaxially fixed on the driven shaft and the driving shaft 4, and a lifting belt meshed between the pulleys on both sides. The hoppers 3 are equidistantly fixed on the lifting belts, and the outer ends of the hoppers 3 are in contact with the inner end face of the shell 1. The driving structure includes a driving seat fixedly mounted on the right end of the shell 1 and a driving motor fixedly mounted on the driving seat. The driving seat is provided with a shaft hole for exposing the output shaft of the driving motor, and both ends of the driving shaft 4 extend out of the shell 1 and are coaxially fixedly connected with the output shaft of the driving motor.

[0027] like Figure 2 and Figure 3 As shown, the top of the feed pipe 8 is connected to the bottom of the storage frame 2, and a quantitative feeding structure is installed between the top of the feed pipe 8 and the bottom of the storage frame 2. A circular chamber is opened at the top of the feed pipe 8. The quantitative feeding structure includes a rotating shaft coaxially mounted and rotatable in the circular chamber, a disc 7 coaxially fixedly mounted on the rotating shaft, and four accommodating chambers 6 circumferentially opened on the disc 7. The accommodating chambers 6 are opened inward from the side wall of the disc 7 and do not extend to the end surfaces of the disc 7. Adjacent accommodating chambers 6 are not connected to each other. In this embodiment, the cross-sectional shape of the opened accommodating chambers 6 is rectangular.

[0028] A partition 11 is also installed in the accommodating chamber 6. Specifically, a plurality of chutes 13 are opened on the disc 7, which are respectively connected to the accommodating chamber 6. The inner walls of both sides of the chutes 13 are bonded with rubber pads that can fit each other. A connecting platform is welded on the inner side of the partition 11, and a stud 12 is fixedly installed on the connecting platform. The stud 12 passes through the rubber pads on both sides and extends out of the disc 7. The stud 12 can slide in the chutes 13 and separate the rubber pads on both sides during the sliding process. When the stud 12 passes the position where it is located, the rubber pads in the original position are closed. A nut is installed at the part where the stud 12 extends out of the chutes 13. The nut is tightened by the nut machine and extends into the partition 11 of the accommodating chamber 6 to play a limiting role. The partition 11 is fixed at a certain height by continuously screwing in the nut to adjust the input amount of the ingredient 10 during each premixed mortar mixing process.

[0029] Furthermore, a retaining plate 5 is welded to each side of the top of the feed pipe 8, fitting against the outer wall of the disc 7. A gap is formed between the retaining plates 5, exposing the accommodating chamber 6. This gap also connects to the storage frame 2 above. Several rotatable material-moving rods 9 are mounted within this gap. Turning the material-moving rods 9 causes them to vibrate, thereby vibrating the material 10 stuck in the gap.

[0030] Moreover, in this embodiment, when any accommodating chamber 6 is communicated with the interior of the shell 1 , only the independent hopper 3 is located at the bottom of the shell 1 .

[0031] A transmission mechanism connecting the driving shaft 4 and the rotating shaft is also installed on the shell 1. Specifically, the transmission mechanism is an intermittent motion mechanism, including a rotatable transmission shaft installed on the shell 1, a sheave 15 and a driving pulley coaxially fixedly installed on the transmission shaft, a rotating arm 14 coaxially fixedly installed on the driving shaft 4, and a driven pulley coaxially fixedly installed on the rotating shaft. A number of cylindrical pins are fixed on the rotating arm 14, which drive the sheave 15 to rotate by entering the radial grooves on the sheave 15 through the cylindrical pins. A transmission belt is engaged between the driving pulley and the driven pulley to intermittently drive the rotating shaft to rotate. Furthermore, each time the hopper 3 reaches the bottom of the shell 1, the accommodating chamber 6 can be connected to the feeding pipe 8 and the ingredients 10 stored therein can be fed into it. The ingredients 10 are then passed into the shell 1 through the feeding pipe 8 and transported via the hopper 3. Moreover, each time the accommodating chamber 6 on the disc 7 is unloaded, only one independent accommodating chamber 6 is unloaded.

[0032] When the utility model is used, while the belt lifting mechanism drives the hopper 3 to move continuously, the rotation of the rotating shaft in the quantitative feeding structure drives the disc 7 to rotate, and the material is stored when the accommodating chamber 6 in the disc 7 is retained in the gap between the two side stops 5. The amount of material stored in the accommodating chamber 6 each time can be controlled by adjusting the installation position of the partition 11, and the rotation of the rotating shaft drives the disc 7 to rotate, and the ingredients 10 stored in the accommodating chamber 6 are put into the feeding pipe 8 and discharged into the bottom end of the shell 1, and the subsequent hopper 3 loads and transports the ingredients 10 discharged this time, and the next level hopper 3 loads and transports the ingredients 10 when the ingredients 10 are discharged next time, thereby completing the quantitative loading of the ingredients 10 in the mixing process of the premixed mortar.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
