[0021] The baffle plate 21 is controlled to slide upward along the discharge pipe 11 and extend into the barrel 10 to open the discharge pipe 11, so that a certain amount of admixture in the barrel 10 slides from the gap between the edge of the baffle plate 21 and the barrel 10 into the receiving box 22, and the baffle plate 21 is controlled to slide downward along the discharge pipe 11 to close the discharge pipe 11; the latch 24 is controlled to slide along the annular groove 25, so that the receiving box 22 drives the admixture therein to vibrate downward, and the admixture is discharged from the discharge port 23 at the bottom of the receiving box 22, thereby realizing intermittent addition of admixture to the mixer. At the same time, the vibration of the receiving box 22 can prevent the admixture from agglomerating, facilitate rapid dispersion, and facilitate rapid and sufficient mixing of the admixture and concrete, thereby improving the mixing efficiency.
[0022] The material barrel 10 and the discharge pipe 11 are arranged above the feed inlet of the mixer.
[0023] The baffle plate 21 has a smooth outer surface so that the additive can slide down along it.
[0024] Preferably, a rotating rod 26 is rotatably provided in the material barrel 10 , a square shaft 27 is slidably provided at the bottom of the rotating rod 26 , and the baffle plate 21 and the material receiving box 22 are jointly arranged on the square shaft 27 .
[0025] The square shaft 27 is driven to rotate by the rotating rod 26 , and the square shaft 27 can slide up and down along the bottom of the rotating rod 26 , thereby driving the receiving box 22 to rotate and slide up and down.
[0026] Preferably, a square hole 28 is opened at the bottom of the rotating rod 26, the upper end of the square shaft 27 is inserted into the square hole 28 through a compression spring 29, the lower end of the square shaft 27 is fixed to the upper end of the rotating shaft 30, the middle part of the rotating shaft 30 is connected to the baffle 21, and the lower end of the rotating shaft 30 is fixed to the bottom of the receiving box 22.
[0027] The middle part of the rotating shaft 30 is fixed to the baffle plate 21 ; of course, the middle part of the rotating shaft 30 can also be rotatably connected to the baffle plate 21 , so that the baffle plate 21 only slides up and down without rotating with the rotating shaft 30 .
[0028] Among them, those skilled in the art can select corresponding sealing components according to needs to prevent additives from affecting the operation of parts in contact with them.
[0029] Preferably, see Figure 2 The annular groove 25 is formed into an annular structure by a spiral ascending groove 251 and a vertical descending groove 252 , the upper end of the spiral ascending groove 251 is connected to the upper end of the vertical descending groove 252 , and the lower end of the vertical descending groove 252 is connected to the lower end of the spiral ascending groove 251 .
[0030] The latch 24 slides along the spiral ascending groove 251 to make the material receiving box 22 rise to receive the material. The latch 24 slides along the vertical descending groove 252, and under the action of the compression spring 29, the material receiving box 22 is rapidly descended and vibrates. The additive in the material receiving box 22 vibrates downward and is discharged from the discharge port 23 at the bottom of the material receiving box 22, thereby avoiding agglomeration of the additive and facilitating rapid dispersion.
[0031] The annular groove 25 may also include two or more groups of spiral ascending grooves 251 and vertical descending grooves 252. Specifically, for example, when there are two groups, see Figure 1 , 3 First, two bayonet pins 24 can be symmetrically arranged about the axis of the receiving box 22 to enhance the connection stability. Secondly, the upper end of the first spiral ascending groove 251 is connected to the upper end of the first vertical descending groove 252, the lower end of the first vertical descending groove 252 is connected to the lower end of the second spiral ascending groove 251, the upper end of the second spiral ascending groove 251 is connected to the upper end of the second vertical descending groove 252, the lower end of the second vertical descending groove 252 is connected to the lower end of the first spiral ascending groove 251... and so on, an annular groove 25 of an annular structure will always be formed; the more groups of spiral ascending grooves 251 and vertical descending grooves 252, the smaller the corresponding central angle of the spiral ascending groove 251, resulting in a shorter interval time of the additive discharged by the receiving box 22, and the corresponding amount of discharged additives will also be reduced, which can be selected according to actual needs.
[0032] Of course, see Figure 4 The structure of the annular groove 25 may also be: including a spiral ascending groove 251 and multiple vertical descending grooves 252. Adjacent vertical descending grooves 252 are connected by transverse grooves 253 to achieve the effect of multiple downward vibrations of the material receiving box 22, which has a better vibration effect and is more conducive to the rapid dispersion of additive agglomerates.
[0033] The track of the slide of the latch pin 24 along the annular groove 25 is as follows: Figure 2-Figure 4 Indicated by the direction of the arrow.
[0034] Among them, technical personnel in this field can set and select the specific structure and size of the annular groove 25 and the length dimensions of the square shaft 27 and the square hole 28 according to actual applications, so that the baffle 21 can slide upward to form a gap between its edge and the barrel 10, so that the additive falls into the receiving box 22.
[0035] Preferably, see Figure 5The baffle 21 is tilted from top to bottom and from the center to the edge.
[0036] The baffle plate 21 is in an umbrella-like shape so that the additive in the center can slide along the baffle plate 21 to the edge thereof.
[0037] Preferably, a motor 31 is fixed to the top of the barrel 10 , and the output shaft of the motor 31 is fixed to the rotating rod 26 . The rotating rod 26 extends into the barrel 10 and is fixed with a spiral blade 32 .
[0038] Among them, the rotation direction of the spiral blade 32 is the same as the rotation direction of the spiral ascending groove 251, so that the spiral blade 32 has a flipping effect on the additive in the barrel 10, further avoiding agglomeration; at the same time, the rotation direction of the motor 31 should make the pin 24 slide along the lower end of the spiral ascending groove 251 to its upper end.
[0039] Preferably, a feeding port 12 is provided at the top of the barrel 10 .
[0040] The working principle of the utility model is as follows:
[0041] Concrete admixture is added into the material barrel 10 through the feeding port 12; when admixture needs to be added to the mixer, the motor 31 is started, and the output shaft of the motor 31 drives the rotating rod 26, the square shaft 27, and the rotating shaft 30 to rotate, driving the receiving box 22 to rotate, so that the latch 24 slides along the annular groove 25.
[0042] Specifically, the latch 24 slides along the spiral ascending groove 251 to make the receiving box 22 rise. During this process, the baffle plate 21 slides upward along the discharge pipe 11 and extends into the barrel 10 to open the discharge pipe 11, so that a certain amount of admixture in the barrel 10 slides from the gap between the edge of the baffle plate 21 and the barrel 10 into the receiving box 22; the latch 24 slides along the vertical descending groove 252, and under the action of the compression spring 29, the receiving box 22 is rapidly descended and vibrated, and the admixture in the receiving box 22 vibrates downward and is discharged from the discharge port 23 at the bottom of the receiving box 22, thereby intermittently adding admixture to the mixer. At the same time, the vibration of the receiving box 22 can prevent the admixture from agglomerating, facilitate rapid dispersion, and facilitate rapid and sufficient mixing of the admixture with concrete, thereby improving the mixing efficiency. During this process, the baffle plate 21 slides downward along the discharge pipe 11 to close the discharge pipe 11.
