Abstract

[0002] There are many kinds of additives for concrete (such as water reducing agent, air entraining agent), etc. Different additives have different raw materials. During the production of existing additives, the proportion of each raw material needs to be strictly controlled, and the proportion is divided into: volume proportion and weight proportion.

For example, in the compounding and stirring stage of naphthalene-based water reducer, different raw materials need to be added to the mother liquor in batches for stirring. In the prior art, different raw materials are directly poured into the mother liquor. Direct pouring will cause the raw materials that first contact with the mother liquor to swell and then wrap up part of the raw materials, which is not conducive to sufficient stirring of the raw materials.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0028] See also Figure 1 to Figure 3 In the embodiment of the utility model, a quantitative feeding mechanism for concrete additive production includes a connecting seat 1 arranged at the top of the edge of the opening of the mixing barrel, the connecting seat 1 is an arc-shaped structure, and the connecting seat 1 is connected to the mixing barrel through a clamping mechanism, the inner periphery of the connecting seat 1 is installed with a follower mechanism, and the outer periphery of the connecting seat 1 is installed with an active mechanism;
[0029] The active mechanism is used to drive the follower mechanism to move in an arc along the inner circumference track of the connecting seat 1;
[0030] A quantitative barrel 5 is sleeved on the follower mechanism, and the quantitative barrel 5 is used to contain raw materials. The follower mechanism in a moving state is used to sprinkle the raw materials contained in the quantitative barrel 5 into the mixing barrel.
[0031] In this embodiment, when producing concrete additives, the raw materials of the additives are added into the quantitative barrel 5 in batches, one raw material is added each time, and after the raw materials are added, the active mechanism is started, and the active mechanism drives the follower mechanism to move, and the follower mechanism drives the quantitative barrel 5 to move. At this time, the raw materials inside the quantitative barrel 5 are scattered into the mixing barrel in an arc trajectory, and then the quantitative barrel 5 is removed and a new quantitative barrel 5 is placed. Each quantitative barrel 5 has the same external shape and area, and different internal volumes, and can be suitable for raw materials of different volumes.
[0032] Please refer to Figure 1, the clamping mechanism includes a No. 1 fixing plate 7, a No. 2 fixing plate 8 and a screw hole 15;
[0033] The first fixing plate 7 is fixedly connected to the inner peripheral edge of the bottom end of the connecting seat 1, and the second fixing plate 8 is fixedly connected to the outer peripheral edge of the bottom end of the connecting seat 1, and there is a docking slot between the outer periphery of the first fixing plate 7 and the inner periphery of the second fixing plate 8 that is plugged into the top edge of the mixing barrel;
[0034] A screw hole 15 is provided at the center of the outer wall of the screw hole 15 , and the screw hole 15 is communicated with the docking slot.
[0035] In this embodiment: when docking the device with the top opening edge of the mixing barrel, the docking slot is inserted into the top opening edge of the fixed connection, and then a bolt is used to penetrate the screw hole 15 and tighten the bolt. As the bolt is tightened, the end of the bolt applies an extrusion force to the outer wall of the mixing barrel. At this time, under the reaction force of the extrusion force, the No. 1 fixing plate 7 moves until it is completely in contact with the inner wall of the mixing barrel. At this time, the bolt is effectively tightened to complete the fixation of the connecting seat 1.
[0036] Please refer to Figure 1 and Figure 2 The follower mechanism includes: a sleeve ring 2, a connecting column 3, a quantitative barrel 5, a groove 6 and a rack 9;
[0037] The groove 6 is formed at the top of the connecting seat 1 and extends downward, the rack 9 is slidably connected to the inner cavity of the groove 6, and the arc trajectory of the rack 9, the groove 6 and the connecting seat 1 is consistent;
[0038] The connecting column 3 is fixedly connected to the top of the rack 9 by bolts, the sleeve ring 2 is fixedly connected to the top of the connecting column 3 by bolts, and the quantitative barrel 5 is sleeved on the inner side of the sleeve ring 2.
[0039] In this embodiment: when the active mechanism is running, the active mechanism drives the rack 9 to slide along the groove 6, and the sliding rack 9 drives the connecting column 3 to move along the groove 6. The connecting column 3 can drive the sleeve ring 2 to move, and the sleeve ring 2 can drive the quantitative barrel 5 to move, thereby achieving the purpose of adding additive raw materials.
[0040] Please refer to Figure 1 , Figure 2 and Figure 3 The active mechanism includes a motor 10, a mounting seat 11, a receiving groove 12 and a gear 13, and the gear 13 is meshed with a tooth block on the outer periphery of the rack 9;
[0041] The receiving groove 12 is fixedly connected to the end of the connection seat 1 away from the quantitative barrel 5 in the initial position. The receiving groove 12 is opened in the middle of the mounting seat 11. A gear 13 is rotatably connected between the top and bottom ends of the inner wall of the receiving groove 12 through a rotating shaft and a bearing. The bearing is located at the connecting position of the rotating shaft and the receiving groove 12.
[0042] The motor 10 is mounted on the top of the mounting seat 11 , and the output end of the motor 10 passes through the inner side of the receiving groove 12 and is connected to the center of the receiving groove 12 . The output end of the motor 10 is rotatably connected to the mounting seat 11 via a bearing.
[0043] In this embodiment, the motor 10 is powered on and starts to run. The motor 10 drives the gear 13 to rotate. The gear 13 can drive the rack 9 to slide along the groove 6 during the rotation.
[0044] Please refer to Figure 2 The inner end of the connecting seat 1 is integrally formed with a connecting frame 14 extending inwardly, and the end of the connecting frame 14 is connected to a bottom cover 4, which is used to cover the output end of the quantitative barrel 5 in the initial position.
[0045] In this embodiment: since the connecting seat 1 remains stationary under the action of the clamping mechanism, the connecting frame 14 and the bottom cover 4 connected to the connecting frame 14 will also remain stationary. When the follower mechanism drives the quantitative barrel 5 to make an arc movement, the bottom cover 4 and the quantitative barrel 5 are separated. At this time, the raw materials in the quantitative barrel 5 lose their cover and can fall into the mixing barrel.
[0046] Please refer to the figure in particular. An opening 16 is provided in the middle of the connecting base 1 for the rack 9 to slide.
[0047] In this embodiment, when the rack 9 moves in an arc shape driven by the active mechanism, the rack 9 slides out of the opening 16. Conversely, when the rack 9 moves in the reverse direction with the active mechanism (i.e., when the motor 10 moves in the reverse direction), the rack 9 completely enters the groove 6 again from the opening 16.
[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
