Description

Technical Field

[0001] This utility model relates to the field of weighing device technology, specifically a weighing device for the mix proportion of sprayed solid waste-based cementitious material concrete. Background Technology

[0002] Current research analyzing factors affecting the performance of shotcrete based on solid waste materials mainly combines concrete strength and shotcrete workability analysis to examine the influence of different water-cement ratios, mortar-cement ratios, total cementitious volume, sand type, water-reducing agent water reduction rate, and fly ash content on the performance of shotcrete based on solid waste materials. Specific methods include using uniform design for mix proportioning, processing experimental data with SPSS software, analyzing the influence of each factor on shotcrete based on solid waste materials, identifying the optimal range for meeting concrete compressive strength and shotcrete performance, analyzing the impact of different curing conditions on shotcrete based on solid waste materials, and designing different water-cement ratios, mortar-cement ratios, and fly ash content under different curing conditions based on the optimal mix proportions obtained from experiments. The analysis further examines the impact of each factor on various aspects of the performance of shotcrete based on solid waste materials under different curing conditions.

[0003] Currently, in terms of mixing different data of raw materials for concrete experiments, existing technologies mostly use direct weighing electronic weighing devices. However, as can be seen from the above-disclosed technologies, concrete experimental raw materials are diverse, and the operation of repeatedly taking and weighing materials is very troublesome and will also prolong the experimental time and reduce the experimental efficiency. Therefore, in order to solve the above problems, this application will provide a weighing device for mixing proportion of sprayed solid waste-based cementitious materials concrete. Utility Model Content

The rear end of the top of the experimental platform is respectively provided with a second support and a multi-position adjustment device. The front end of the second support is fixed with a main material pipe located above the middle of the material box.

[0006] The multi-station adjustment device includes a first bracket, a brake stepper motor, and several limiting sleeves. The housing of the brake stepper motor is fitted inside the top of the first bracket, and the bottom of the first bracket is fixed to the surface of the rear end of the top of the experimental platform. A storage tank is fitted inside one end of each of the limiting sleeves, and the other ends of the limiting sleeves are arranged and installed along the circumference of the first bracket on the output end of the brake stepper motor. A solenoid valve discharge pipe that can connect to the top port of the main material pipe is installed at the bottom of each of the storage tanks.

[0007] The selected configuration has three of each of the limiting sleeves and three of each of the storage tanks, and each of the three storage tanks has a sealing cap threaded to its top port.

[0008] Selectedly, the outer side of the top of the main feed tube is fitted with a protective box installed on the top of the experimental table, and the front inner side of the protective box is hinged with a door by a pin, and a transparent observation plate is nested inside the door.

[0009] Specifically, a transition conduit is connected to the outside of the main feed tube by a sealing ring, an electric push rod is installed on the outside of the top of the main feed tube, and a linkage plate is installed between the output end of the electric push rod and the top of the transition conduit.

[0010] Preferably, the outer side of the transition conduit is provided with a meshing output assembly, which includes a gear sleeve, a transmission gear, and a servo low-speed motor.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4 A weighing device for mix proportion of sprayed solid waste-based cementitious material concrete includes an electronic weighing device body 1, an experimental platform 2 installed at the bottom of the electronic weighing device body 1, and a material box 3 placed on the weighing platform at the top of the electronic weighing device body 1. A second support 8 and a multi-position adjustment device are respectively provided at the rear end of the top of the experimental platform 2. A main material pipe 9 located above the middle of the material box 3 is fixed at the front end of the second support 8.

[0027] The multi-station adjustment device includes a first bracket 4, a brake stepper motor 5, and several limiting sleeves 6. The housing of the brake stepper motor 5 is fitted inside the top of the first bracket 4, and the bottom of the first bracket 4 is fixed to the surface of the rear end of the top of the experimental table 2. A storage tank 7 is fitted inside one end of each of the several limiting sleeves 6, and the other end of the several limiting sleeves 6 is arranged and installed along the circumference of the first bracket 4 on the output end of the brake stepper motor 5. A solenoid valve discharge pipe that can connect to the top port of the main material pipe 9 is installed at the bottom of each of the several storage tanks 7.

[0028] The number of limiting sleeves 6 and the number of storage tanks 7 are the same, both being three. The top ports of the three storage tanks 7 are threaded with sealing caps. The outer side of the top of the main material pipe 9 is fitted with a protective box 10 installed on the top of the experimental platform 2. The inner side of the front end of the protective box 10 is hinged with a door 11 by a pin. The inside of the door 11 is nested with a transparent observation plate.

[0029] Specific usage of this embodiment:

[0030] When the brake stepper motor 5 is activated, the output end of the brake stepper motor 5 drives the limit sleeve 6 and the three storage tanks 7 to rotate at equal intervals. Each rotation adjustment will align one storage tank 7 with the main feed tube 9, and the open port of the solenoid valve discharge pipe at the bottom of the storage tank 7 will be aligned and fit with the port at the top of the main feed tube 9.

[0031] Place the material bin 3 on the weighing platform on top of the electronic weighing device body 1, close the box door 11 and turn on the electronic weighing device body 1. Open the solenoid valve in the discharge pipe of the corresponding storage tank 7. The raw material inside the storage tank 7 will flow into the material bin 3 through the main feed pipe 9. During this period, the electronic weighing device body 1 will display the material weight in real time. After the specified amount is reached, close the solenoid valve in the discharge pipe to stop the material feeding. Subsequently, the weighing of the raw material in the remaining two storage tanks 7 will be carried out in the same manner.

[0032] Example 2

[0033] Please see Figure 1 , Figure 5-6 A transition conduit 12 is connected to the outside of the main feed pipe 9 by a sealing ring. An electric push rod 14 is installed on the outside of the top of the main feed pipe 9. A linkage plate is installed between the output end of the electric push rod 14 and the top of the transition conduit 12.

[0034] A meshing output assembly 13 is provided on the outer side of the transition conduit 12. The meshing output assembly 13 includes a gear sleeve 131, a transmission gear 132, and a servo low-speed motor 133. The inner side of the middle part of the gear sleeve 131 is fitted with the top structure of the transition conduit 12 through a bearing, and the outer side of the top of the gear sleeve 131 meshes with the transmission gear 132 for transmission. The output end of the servo low-speed motor 133 is connected to the middle part of the transmission gear 132 for transmission. A rear auxiliary support is installed between the surface of the housing of the servo low-speed motor 133 and the surface of the top of the transition conduit 12.

[0035] A flow guiding assembly is provided at the bottom of the transition conduit 12. The flow guiding assembly includes an inverted T-shaped bracket 15 and an extended guide plate 16. The top and bottom of the inverted T-shaped bracket 15 are fixed to the surface of the gear sleeve 131 and the inner side of the middle of the extended guide plate 16, respectively. The extended guide plate 16 is fitted with the bottom of the inverted T-shaped bracket 15 in an inclined state with the side closer to the transition conduit 12 higher and the side farther from the transition conduit 12 lower. One side of the extended guide plate 16 extends to the open area of ​​the bottom port of the transition conduit 12, which is conducive to further extending the length of the material conveying channel and making the weighed raw material evenly spread inside the material box 3.

[0036] Specific usage of this embodiment:

[0037] Considering the problem of multiple raw materials accumulating too much in one place and coming into contact with the working structure, before the actual material feeding, the electric push rod 14 is activated. The output end of the electric push rod 14 drives the transition conduit 12 and the structure associated with the transition conduit 12 to move and be fitted into the inside of the material box 3 under the guidance of the main material pipe 9. Subsequently, the box door 11 is closed and the electronic weighing device body 1 is activated. The solenoid valve in the discharge pipe of the corresponding storage tank 7 is opened. The raw materials inside the storage tank 7 will enter the inside of the material box 3 through the extended channel of the main material pipe 9 and the transition conduit 12. At the same time as the raw materials flow out of the bottom port of the transition conduit 12, the servo low-speed motor 133 is activated. The output end of the servo low-speed motor 133 meshes with the transmission gear sleeve 131 through the transmission gear 132, thereby causing the inverted T-shaped bracket 15 and the extended guide plate 16 to rotate synchronously with the gear sleeve 131. Then, some of the raw materials will first flow into the inside of the extended guide plate 16 and be dispersed into the space of the edge area of ​​the material box 3 under the action of the centrifugal force of the rotation of the extended guide plate 16, maintaining the uniform feeding effect.

[0038] As the amount of raw material inside the material box 3 increases, in order to avoid structural interference, the electric push rod 14 can be turned off to lift the transition conduit 12 and the structure associated with the transition conduit 12, and then the above feeding steps can be repeated.
