Description

Technical Field

[0001] This application belongs to the field of tubular column production technology, and in particular relates to a concrete quantitative feeding device for tubular column production. Background Technology

[0002] During concrete mixing, the required materials are stirred according to their proportions. At the same time, in order to improve the performance of concrete, a certain proportion of admixtures are often added during concrete mixing. Admixtures can improve the chemical properties of concrete, resulting in better quality of the tubular column.

[0003] In existing technologies, the dosage of admixtures is controlled by manual addition or by controlling the conveyor belt speed.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: manual addition requires operators to pay close attention to the mixing process at all times, which is labor-intensive and inefficient; adjusting the conveyor belt speed to control the amount of admixture added cannot be done according to the actual quality of the concrete; and the admixture is not mixed evenly with the concrete during addition.

[0005] To address this issue, we propose a concrete metering device for tubular column production. Utility Model Content

[0006] The purpose of this application is to solve the problems in the prior art, such as the need for operators to constantly monitor the mixing process when adding admixtures manually, which is labor-intensive, inefficient, and the inability to adjust the amount of admixtures added by adjusting the speed of the feeding conveyor belt, which cannot be based on the actual quality of the concrete, and the uneven mixing of the admixtures with the concrete. Therefore, this application proposes a concrete quantitative feeding device for pipe column production.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A concrete quantitative feeding device for producing tubular columns includes a shell and a mixing tank. A lifting mechanism is provided at the bottom of the shell, and the mixing tank is provided above the lifting mechanism. A motor is fixedly provided at the upper end of the mixing tank, and the output end of the motor extends into the interior of the mixing tank. The output end of the motor is connected to the mixing mechanism.

[0009] The mixing tank is provided with a storage hopper at the upper end, and a conveying pipe is connected to the lower end of the storage hopper. The lower end of the conveying pipe passes through the upper end of the shell. A connecting rod is provided inside the conveying pipe. Spherical limiting blocks are provided at both ends of the connecting rod. The diameter of the spherical limiting blocks matches the diameter of the conveying pipe, and the length of the connecting rod is longer than the length of the conveying pipe.

[0010] By setting spherical limiting blocks at both ends of the connecting rod, which is located inside the conveying pipe, and adjusting the spherical limiting blocks up and down through the stirring mechanism, the additives can be quantitatively added into the mixing tank.

[0011] Preferably, the lifting mechanism includes telescopic rods and springs. Multiple telescopic rods are arranged in a circumferential array at the bottom of the housing. Multiple springs are arranged in a circumferential array at the bottom of the housing. The springs are matched with the telescopic rods. A stirring tank is connected above the telescopic rods.

[0012] By setting up a telescopic rod, which works in conjunction with a spring, the mixing tank is supported inside the shell. When the weight of raw materials inside the mixing tank is different, the height of the mixing tank is different, thereby adjusting the length of the conveying pipe and achieving the effect of quantitatively adding admixtures.

[0013] Preferably, the stirring device includes a rotating shaft, stirring rods, and stirring blades. The rotating shaft is vertically rotatable inside the stirring tank. Multiple stirring rods are fixed on the rotating shaft, and the multiple stirring rods are spirally arranged on the rotating shaft. Stirring blades are spirally arranged at the ends of the multiple stirring rods away from the rotating shaft.

[0014] By setting up stirring blades, which are spirally arranged inside the mixing tank via multiple stirring rods and rotated by a rotating shaft, the raw materials inside the mixing tank are thoroughly mixed.

[0015] Preferably, an arc-shaped plate is connected to the upper end of the stirring blade, the arc-shaped plate is coaxially arranged with the spherical limiting block, and the arc-shaped plate is in contact with the upper part of the inner wall of the stirring tank.

[0016] By setting an arc-shaped plate, which is positioned above the stirring blades and fits against the upper part of the inner wall of the mixing tank, the additives inside the delivery pipe can be added.

[0017] Preferably, the conveying pipe is a corrugated pipe, with the upper end of the conveying pipe fixedly installed at the discharge port of the storage hopper, and the lower end of the conveying pipe fixedly installed above the mixing tank.

[0018] By setting up a conveying pipe, which is a corrugated pipe, with the upper end of the conveying pipe fixed at the discharge port of the storage hopper and the lower end fixed above the mixing tank, the internal space of the conveying pipe changes when the mixing tank is at different heights, thus achieving the purpose of quantitatively adding admixtures.

[0019] Preferably, a fixing rod is fixedly provided on one side of the storage hopper, and the end of the fixing rod away from the storage hopper is fixedly provided on the upper part of the shell.

[0020] By setting a fixing rod, the storage hopper is fixed above the shell, thus ensuring that the position of the storage hopper does not change when the mixing tank is lowered and the conveying pipe is adjusted.

[0021] Preferably, a limiting ring is provided above the mixing tank, the limiting ring is fixedly disposed on the upper end face of the shell and the inner side of the limiting ring protrudes towards the inner side of the shell.

[0022] By setting a limiting ring, which is fixedly positioned above the housing, the purpose of preventing the mixing tank from being pushed out of the housing by the lifting mechanism is achieved.

[0023] Preferably, the connecting rod and the spherical limiting block are made of stainless steel.

[0024] By making the connecting rod and the spherical limit block from stainless steel, the purpose of preventing rust and extending service life is achieved.

[0025] In summary, the technical effects and advantages of this application are as follows: the concrete quantitative feeding device for pipe column production, by setting up a lifting mechanism to adjust the height of the mixing drum, adjusts the internal space of the conveying pipe, and by cooperating with the mixing device and the spherical limiting block, achieves the purpose of adding admixtures according to the actual quality of concrete and mixing them evenly with the concrete during addition.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] Reference Figure 1-3A concrete quantitative feeding device for pipe column production includes a housing 1 and a mixing tank 2. The bottom of the housing 1 is provided with a lifting mechanism 333 for adjusting the height of the mixing tank 2. The mixing tank 2 is positioned above the lifting mechanism 333. A motor 13 for driving is fixedly installed at the upper end of the mixing tank 2, and the output end of the motor 13 extends into the interior of the mixing tank 2.

[0033] refer to Figure 2-4 The output end of the motor 13 is connected to a stirring mechanism 555 for stirring. The upper end of the stirring tank 2 is provided with a storage hopper 4 for storing additives. The lower end of the storage hopper 4 is connected to a conveying pipe 5 for transporting additives. The conveying pipe 5 is a corrugated pipe, and the lower end of the conveying pipe 5 passes through the upper end of the shell 1. A connecting rod 3 is provided inside the conveying pipe 5. Spherical limiting blocks 6 for limiting are provided at both ends of the connecting rod 3. The diameter of the spherical limiting blocks 6 matches the diameter of the conveying pipe 5, and the length of the connecting rod 3 is longer than the length of the conveying pipe 5, thereby achieving the effect of quantitatively adding the additives into the stirring tank 2.

[0034] The lifting mechanism 333 includes telescopic rods 7 and springs 8. Multiple telescopic rods 7 are arranged in a circumferential array at the bottom of the housing 1. At the same time, multiple springs 8 are arranged in a circumferential array at the bottom of the housing 1, and the springs 8 are matched with the telescopic rods 7. A mixing tank 2 is connected above the telescopic rods 7 and supports the mixing tank 2 inside the housing 1. When the mixing tank 2 contains raw materials of different weights, the height of the mixing tank 2 will be different, thereby realizing the adjustment of the length of the conveying pipe 5 and achieving the effect of quantitatively adding additives.

[0035] In addition, the upper end of the conveying pipe 5 is fixedly installed at the discharge port of the storage hopper 4, and the lower end of the conveying pipe 5 is fixedly installed above the mixing tank 2. This allows the internal space of the conveying pipe 5 to change when the mixing tank 2 is at different heights, thereby achieving the purpose of quantitatively adding additives.

[0036] A limiting ring 14 is provided above the mixing tank 2 to prevent the mixing tank 2 from detaching from the housing 1. The limiting ring 14 is fixedly installed on the upper end face of the housing 1 and the inner side of the limiting ring 14 protrudes towards the inner side of the housing 1, thereby achieving the purpose of preventing the mixing tank 2 from being pushed out of the housing 1 by the lifting mechanism 333.

[0037] A fixing rod 10 is fixedly installed on one side of the storage hopper 4. The end of the fixing rod 10 away from the storage hopper 4 is fixedly installed above the shell 1, so that the position of the storage hopper 4 will not change when the mixing tank 2 is lowered and the conveying pipe 5 is adjusted.

[0038] refer to Figure 2-3The stirring mechanism 555 includes a rotating shaft 9, stirring rods 11, and stirring blades 12. The rotating shaft 9 is vertically rotatable inside the stirring tank 2. Multiple stirring rods 11 are fixed on the rotating shaft 9 and spirally arranged on the rotating shaft 9. The same stirring blade 12 is spirally arranged at the end of the multiple stirring rods 11 away from the rotating shaft 9. An arc-shaped plate 15 is connected to the upper end of the stirring blade 12. The arc-shaped plate 15 is coaxially arranged with the spherical limiting block 6. When the arc-shaped plate 15 contacts the spherical limiting block 6, the bottom spherical limiting block 6 is raised, and the additive is added into the stirring tank 2. The arc-shaped plate 15 is in contact with the upper part of the inner wall of the stirring tank 2. The connecting rod 3 and the spherical limiting block 6 are made of stainless steel, thereby achieving the effect of fully mixing the raw materials inside the stirring tank 2 and preventing the connecting rod 3 and the spherical limiting block 6 from rusting, thus extending their service life.

[0039] Working principle: When adding concrete raw materials into the mixing drum 2, the lifting mechanism 333 lowers the weight of the added raw materials, stretching the conveying pipe 5. After thorough mixing, when adding admixtures into the mixing drum 2, the admixtures are first added into the storage hopper 4. The motor 13 is started, and the motor 13 drives the mixing mechanism 555 to rotate. The arc plate 15 follows the rotation of the mixing mechanism 555, pushing the spherical limiting block 6 upward. The admixtures inside the conveying pipe 5 then enter. After the spherical limiting block 6 disengages from the arc plate 15 and returns to its original position, the admixtures inside the conveying pipe 5 are added into the mixing drum 2. After mixing is completed, the motor 13 is turned off. Through the above structure, the admixtures are added according to the actual weight of the concrete, and the admixtures are mixed evenly with the concrete during addition.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
