Furthermore, when the material distribution is controlled by the opening and closing door device, the concrete slurry falling into the precast part mold is mainly concentrated in the middle position, requiring the operator to disperse the concrete slurry to both sides, increasing the operator's work intensity.

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.
[0033] Figure 1 , Figure 2 , Figure 3 and Figure 4 The figure shows a concrete distribution control device disclosed in the utility model, which is used to control the injection of concrete into a prefabricated component mold, and includes: a control device body 1, a material distribution mechanism, a material guide mechanism 3, a hopper 4 and a baffle 5;
[0034] The upper and lower ends of the control device body 1 are respectively provided with a feed port 11 and a discharge port 12, and a receiving chamber 13 is provided inside the control device body 1; the hopper 4 is fixedly arranged at the upper end of the control device body 1 and communicated with the feed port 11;
[0035] The material distribution mechanism includes a driving device 20 and a pair of impellers 21. The pair of impellers 21 are arranged in parallel in the accommodating chamber 13. The driving device 20 is connected to the impellers 21.
[0036] A pair of baffles 5 are provided at the feed inlet 11 of the control device body 1 along the axial direction of the impeller 21, and the pair of baffles 5 separate the feed inlet 11 into a first feed inlet 110 and a second feed inlet 111 located outside the rotating shaft 210 of the pair of impellers 21; Figure 1 , Figure 3 and Figure 4As shown, preferably, a pair of baffles 5 have a cross-section perpendicular to the axis of the impeller 21 that is an isosceles triangle, and the symmetry plane of the isosceles triangle is vertically arranged, so that the concrete put into the hopper 4 enters the two impellers 21 along the inner walls on both sides of the control device body 1 respectively, and the driving device 20 can drive the two impellers 21 to rotate relative to each other, and can discharge the concrete entering between the impeller and the inner wall of the control device body 1 from the first feed port and the second feed port through the outer space of the rotating shaft 210 of the impeller from the discharge port 12 to the material guide mechanism 3, and introduce the concrete into the prefabricated part mold through the material guide mechanism 3.
[0037] Specifically, the present application realizes the control of concrete distribution by setting a pair of impellers. When the pair of impellers 21 rotate relative to each other, the faster the impeller 21 rotates, the faster the material discharge speed, and the slower the impeller 21 rotates, the slower the material discharge speed. When the impeller 21 stops rotating, the concrete does not fall. Thus, the pair of impellers 21 can control the concrete entering from the feed port 11 on both sides of the baffle 5 to be discharged from the discharge port 12 respectively. Controlling the rotation speed and rotation time of the pair of impellers 21 can control the concrete discharge speed and supply amount, thereby realizing the quantitative distribution of concrete. At the same time, since a pair of baffles are set at the inlet of the control device body, the baffles can discharge the concrete in the hopper from the outside of the rotating shafts of the two impellers into the space between the impellers and the inner wall of the control device body. When the impellers are at the inlet of the control device body, the baffles can discharge the concrete in the hopper from the outside of the rotating shafts of the two impellers into the space between the impellers and the inner wall of the control device body. Figure 4 When the two impellers rotate in the direction indicated by the middle arrow (when the two impellers rotate relative to each other, the upper parts of the two impellers rotate out from the middle to the outside, and the lower parts of the two impellers rotate in from the outside to the middle), the concrete is discharged from the outer space of the rotating shaft through the discharge port to the material guide mechanism through the rotation of the impeller, and then the concrete is introduced into the prefabricated part mold through the material guide mechanism, that is, when the concrete is discharged from the outer space of the rotating shaft of the impeller to the material guide mechanism, the position of the concrete falling is controlled to be more uniform, and the aggregate in the concrete can be relatively evenly arranged in various places in the prefabricated part mold, so as to further ensure the quality of the prefabricated part. For example, when the concrete distribution control device is used to distribute square piles, the aggregate in the concrete can be evenly distributed along the width direction of the mold, so that a certain amount of aggregate can be arranged in the body and corners of the prefabricated square pile, thereby ensuring the quality of the prefabricated pile, especially improving the strength of the four corners of the square pile.
[0038] Furthermore, the plane of the rotating shaft of a pair of impellers is a horizontal plane, and the projection of the lower edge of the baffle on the horizontal plane is located on the outside of the rotating shaft of the impeller, that is, the width distance between the lower edges of the two baffles is greater than the distance between the rotating shafts of the two impellers, and the lower edge of the baffle is located at the upper outer side of the rotating shaft of the impeller. Therefore, when the concrete in the hopper enters between the impeller and the inner wall of the control device body along the baffle, the impact force of the concrete will be able to provide a certain driving force to the impeller, and then a smaller power driving device can be used to drive the impeller to rotate. In this embodiment, the impeller driving device adopts a driving motor. Therefore, a small power motor can be used to drive the impeller, which not only reduces the cost and power consumption of the equipment, but also reduces the size of the equipment.
[0039] Combination Figure 1 , Figure 3 and Figure 4 As shown, a pair of arc plates 6 are provided directly below the baffle 5, and the pair of arc plates 6 are symmetrical to each other with the symmetry plane of the two baffles 5; one end of the arc plate 6 abuts against the edge at the bottom corner of the baffle 5, and the other end extends to the symmetry plane of the isosceles triangle; the arc of the arc plate 6 is arranged along the outer diameter of the impeller 21. The arc plate cooperates with the impeller 21 to prevent the concrete from rotating to the middle position of the baffle 5 and flowing out of the impeller 21, and restricts the concrete on the pair of impellers 21 from moving along their respective rotation directions, preventing too much concrete from falling to the middle position of the prefabricated mold, causing uneven distribution.
[0040] Combination Figure 1 , Figure 4 and Figure 5 As shown, the impeller 21 includes a rotating shaft 210 and a plurality of blades 211 fixed on the rotating shaft 210, and the length of the blades 211 is adapted to the radius of the arc plate 6. Both ends of the rotating shaft 210 are mounted on the control device body 1 through bearings and other components and connected to the drive device 20. A plurality of blades 211 are evenly distributed on the rotating shaft 210. The number of blades 211 in the figure is 5, and the specific number can be set as needed. There is a gap between the end of the blade 211 and the inner side of the accommodating cavity 13 and the arc plate 6, so that the blade 211 can slide smoothly and prevent concrete leakage.
[0041] Combination Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the driving device 20 includes: a driving motor 200, a reducer 201 and a transmission mechanism 202; the transmission mechanism 202 includes a pair of gears 203 installed at one end of the rotating shaft 210 and meshing with each other, and the driving motor 200 drives a pair of impellers 21 to rotate synchronously in opposite directions through the reducer 201 and the pair of gears 203. The driving motor 200, the reducer 201 and the transmission mechanism 202 are all arranged at one end of the control device body 1, and a gear 203 is respectively installed on the part where the two rotating shafts 210 extend out of the end of the control device body 1, and the two gears 203 are externally meshed with each other. The driving motor 200 drives one of the rotating shafts 210 to rotate through the reducer 201, and the other rotating shaft 210 rotates synchronously with the rotating shaft 210 due to the meshing of the two gears 203. Further, a set of transmission mechanisms 202 are respectively arranged at both ends of the pair of impellers 21. That is, a group of transmission mechanisms 202 are respectively provided at both ends of the control device body 1 to realize transmission at both ends of the rotating shaft 210 through the gears 203, so that both ends of the rotating shaft 210 are subjected to force during the rotation of the pair of impellers 21, which can ensure that the pair of impellers 21 are subjected to force more smoothly and operate more reliably, and also improve the service life of the impellers 21.
[0042] Combination Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the material guiding mechanism 3 includes a pair of movable doors 30 arranged on both sides of the material outlet 12 and a driving mechanism 31 arranged on the control device body 1 for driving the movable doors 30 to rotate. The driving mechanism 31 is a hydraulic cylinder or a pneumatic cylinder. In this embodiment, the driving mechanism 31 is a hydraulic cylinder. One end of the cylinder body of the hydraulic cylinder is hinged on the control device body 1, and one end of the piston rod of the hydraulic cylinder is hinged to the movable door 30.
[0043] Specifically, in the present embodiment, a hydraulic cylinder fixing seat 310 is fixed on the end surface of the control device body 1, one end of the hydraulic cylinder body is hinged on the hydraulic cylinder fixing seat 310 through a pin shaft, a connecting block 311 is provided at one end of the piston rod of the hydraulic cylinder, and an arc groove 312 is provided on the end surface of the control device body 1 near the end of the hydraulic cylinder piston rod, one end of the connecting block 311 is hinged at the end of the hydraulic cylinder piston rod, and the other end is fixedly connected to the movable door 30 after passing through the arc groove 312, and the extension and retraction of the piston rod can realize the swing of the movable door 30 relative to the control device body 1, and then the size of the lower end outlet of the movable door 30 can be adjusted, so that the lower end width of the movable door 30 corresponds to the width of the prefabricated part mold, ensuring that the concrete discharged from the discharge port 12 is distributed to the entire width range of the prefabricated part mold under the action of the movable door 30, and it can be ensured that the concrete distribution control device is suitable for the distribution of prefabricated part molds of different models.
[0044] Furthermore, the movable door 30 is connected to the control device body 1 via a rubber sheet 7, the length of the rubber sheet 7 is consistent with the length of the movable door 30, and the movable door 30 is connected to the control device body 1 via the rubber sheet 7. Since the rubber sheet 7 is elastic, the movable door 30 can swing relative to the control device body 1 to a certain extent. At the same time, it can also prevent concrete from leaking from between the movable door 30 and the control device body 1.
[0045] The principle of the device in this application:
[0046] The action of the hydraulic cylinder drives the connecting block 311 to slide along the arc groove 312, and the connecting block 311 drives the movable door 30 to swing, so that the lower end width of the movable door 30 corresponds to the width of the prefabricated mold. The driving motor 200 is started, and the driving motor 200 drives a gear 203 to rotate through the reducer 201. The gears mesh with each other and drive a pair of impellers 21 to rotate synchronously in opposite directions. Concrete is put into the hopper 4, and the concrete enters the two impellers 21 along the inner walls of the two sides of the control device body 1 through the diversion of the baffle 5. The concrete is driven by the pair of impellers 21 and discharged from the discharge port 12.
[0047] By controlling the start and stop of a pair of impellers 21, the start and stop of concrete distribution are controlled; by controlling the rotation speed and time of a pair of impellers 21, the speed and supply amount of concrete distribution are controlled; by controlling the rotation speed and rotation direction of a pair of impellers 21, the dispersion of concrete in the prefabricated part mold is controlled, so that the aggregate in the concrete is dispersed more evenly, thereby ensuring the quality of the prefabricated parts.
