DETAILED DESCRIPTION
[0026] The present invention is further described in detail below in conjunction with the embodiments:
[0027] Example 1
[0028] like Figure 1-5 As shown, the utility model provides a high-performance concrete experimental proportioning device, comprising a mixing box 1, a motor 2 is fixedly connected to the middle of the top of the mixing box 1, a mixing shaft 21 is fixedly connected to the bottom of the rotating shaft of the motor 2, a mixing blade 22 is fixedly connected to the left and right ends of the mixing shaft 21, a mixing blade 23 is fixedly connected to the middle of the surface of the mixing shaft 21, a mixing shaft 24 is fixedly connected to the bottom of the mixing shaft 21, a scraper 25 is fixedly connected to the outer side of the mixing shaft 24, a base 6 is fixedly connected to the bottom of the mixing box 1, a chassis 7 is fixedly connected to the middle of the bottom of the mixing box 1, transparent temporary storage boxes 3 are fixedly connected to the two ends of the top of the mixing box 1, a material injection port 4 is fixedly connected to the outer side of the top of the transparent temporary storage box 3, a scale 5 is fixedly connected to the front of the surface of the transparent temporary storage box 3, a material control mechanism is arranged at the two ends of the top of the mixing box 1 and located on the outer side of the transparent temporary storage box 3, and a vibration mechanism is arranged in the middle of the left outer wall of the mixing box 1;
[0029] The material control mechanism includes a receiving plate 4 31, which is fixedly connected to the outer wall of the transparent temporary storage box 3, and the right end of the receiving plate 4 31 is rotatably connected to the gear 2 32, and the gear 2 32 is fixedly connected to the rotating rod 33. The outer wall of the transparent temporary storage box 3 and located below the receiving plate 4 31 are fixedly connected to the receiving plate 3 34, and the inner cavity of the receiving plate 34 is movably sleeved with a tooth plate 2 35, and the tooth plate 2 35 is provided with teeth on the upper and lower surfaces, and the gear 2 32 is meshed with the upper surface of the tooth plate 2 35;
[0030] A slide bar 44 is slidably provided on the outer wall of the transparent temporary storage box 3 below the receiving plate three 34, and a material injection baffle 45 is fixedly connected to the left end of the slide bar 44, and a vertical plate 37 is fixedly connected to the right end of the slide bar 44 through a buckle 39, and a rack 40 is provided on the top of the vertical plate 37. The slide bar 44 passes through the limit block 43 and is slidably connected to the limit block 43, and a receiving plate two 42 is fixedly connected to the bottom of the limit block 43, and the left end of the receiving plate two 42 is fixedly connected to the surface of the mixing box 1, and a slide groove 38 is provided on the top of the receiving plate two 42, and the slide groove 38 is slidably connected to the vertical plate 37, and a connecting column 41 is fixedly connected to the rear side of the vertical plate 37, and a gear three 36 is rotatably connected to the top of the connecting column 41, and the gear three 36 is meshed with the rack 40, and the gear three 36 is meshed with the lower surface of the toothed plate two 35.
[0031] In this embodiment, by pushing the rotating rod 33 upward, the gear 2 32 fixedly connected to the rotating rod 33 starts to rotate, so the toothed plate 2 35 starts to move to the right, so the gear 36 will rotate. During the rotation of the gear 36, since the gear 36 is meshed with the rack 40 at the top of the vertical plate 37, the vertical plate 37 moves to the right in the slide groove 38, and then the vertical plate 37 drives the slide bar 44 on its left side to move to the right, so that the injection baffle 46 also moves to the right. Due to the support of the limit block 43, the movement of the slide bar 44 is more stable, so as to control the addition of water or raw materials. The proportion is determined by observing the scale installed on the transparent temporary storage box 3 to achieve a more accurate proportion control effect. Subsequently, the motor 1 2 is started to make the stirring shaft 21 start to rotate, thereby driving the stirring blade 1 22, the stirring blade 23, and the stirring shaft 24 to rotate, completing the mixing of the concrete. After the mixing is completed, the chassis 7 is opened to discharge the concrete.
[0032] Example 2
[0033] like Figure 1-5 As shown, the vibration mechanism includes a receiving plate 11, the receiving plate 11 is fixedly connected to the middle of the left outer wall of the mixing box 1, a motor 12 is fixedly connected to the middle of the top of the receiving plate 11, a rotating shaft 13 is fixedly connected to the top of the rotating shaft of the motor 12, a gear 14 is fixedly connected to the surfaces of the upper and lower ends of the rotating shaft 13, a tooth plate 16 is meshed with the surface of the gear 14, the right end of the tooth plate 16 is fixedly connected to a limiting plate 17, the middle of the left side of the outer wall of the mixing box 1 is fixedly connected to the limiting plate 17, the middle of the tooth plate 16 is movably sleeved with the surface of the limiting plate 17, the interior of the limiting plate 17 is fixedly connected to a spring 15, and the right end of the spring 15 is fixedly connected to the left end of the tooth plate 16;
[0034] When concrete is stuck to the inner wall of the mixing box 1, the motor 2 12 is started. Through the action of the motor 2 12, the shaft 13 starts to rotate, thereby driving the gear 14 to rotate, and the tooth plate 16 starts to move to the left. When the angle of the gear 14 rotates more than half, under the action of the spring 15, the tooth plate 16 moves quickly to the right to collide with the mixing box 1, and this process is repeated continuously. The vibration generated during the collision will cause the sticky concrete to fall off.
[0035] The working principle of the high performance concrete experimental mix device is described in detail below.
[0036] like Figure 1-5 As shown, first, water and raw materials are poured into the two transparent temporary storage boxes 3 from the injection port 4, respectively, and the rotating rod 33 is pushed upward to make the gear 2 32 fixedly connected to the rotating rod 33 start to rotate. Since the gear 2 32 and the tooth plate 2 35 are meshed with each other, the tooth plate 2 35 starts to move to the right. Since the gear 3 36 and the tooth plate 2 35 are meshed with each other, the gear 3 36 will be driven by the tooth plate 2 35 to rotate. During the rotation of the gear 3 36, since the gear 3 36 is meshed with the rack 40 at the top of the vertical plate 37, the vertical plate 40 slides to the right in the slide groove 38 on the receiving plate 42, thereby driving the slide rod 44 and the injection baffle 45 to move to the right, thereby achieving the control of the addition of water or raw materials, and the proportion is determined by observing the scale installed on the transparent temporary storage box 3, so as to achieve a more accurate Proportional control effect, then start the motor 2, so that the stirring shaft 21 starts to rotate, and then drives the stirring blade 22, the stirring blade 23, and the stirring shaft 24 to rotate, and complete the mixing of the concrete. After the mixing is completed, open the chassis 7 to release the concrete. When the inner wall of the mixing box 1 is stuck with concrete, start the motor 2 12. Through the action of the motor 2 12, the shaft 13 starts to rotate, thereby driving the gear 14 to rotate, and the tooth plate 16 meshing with the gear 14 starts to move to the left. Since the teeth of the gear 14 are only half, when the rotation angle exceeds half, under the action of the spring 15, the tooth plate 16 moves quickly to the right, collides with the mixing box 1, and continuously repeats this process. The vibration generated during the collision will cause the sticky concrete to fall off.
[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
