Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, and in particular to a variable metering pouring device and method for secondary mixing of concrete. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. The existing pouring device required for the secondary mixing of concrete (including light concrete) components generally uses a hopper installed under the secondary mixing equipment as a metering pouring device. Although it is relatively accurate for the metering and pouring of fixed volume components, if the volume of the component changes, it will be difficult to adjust the hopper volume for component pouring. It is necessary to manually replace the hopper with the volume required by the component for re-pouring, but it will also reduce production efficiency and increase certain equipment investment costs. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the above-mentioned and / or existing problems in the existing pouring device for secondary mixing of concrete, the present invention is proposed.

[0005] Therefore, the problem to be solved by the present invention is how to provide a novel variable metering pouring device and method for secondary mixing of concrete.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] In one aspect, the present invention provides a variable metering pouring device for secondary mixing of concrete, comprising:

[0008] A secondary stirring mechanism, comprising a stirring tank and a reduction motor mounted on the stirring tank;

[0009] A movable pouring hopper mechanism is arranged at the lower part of the secondary mixing mechanism; the movable pouring hopper mechanism comprises a pouring hopper and a hopper driving unit for driving the pouring hopper to reciprocate, the pouring hopper has a first limit position and a second limit position, when the pouring hopper is located at the first limit position, the concrete in the secondary mixing mechanism enters the pouring hopper through the first discharge port at the bottom thereof; when the pouring hopper is located at the second limit position, the concrete in the pouring hopper is discharged through the bottom thereof;

[0010] The conveying unit is arranged at the lower part of the movable casting hopper mechanism, and a component mold is placed on the upper part of the conveying unit for receiving concrete from the casting hopper.

[0011] Based on the above technical features: the present application can use a set of devices to achieve the metered pouring of components of different volumes. If the volume of the component mold changes, it is only necessary to set the appropriate pouring times of the pouring hopper according to the volume of the component. There is no need to replace it with a pouring hopper that meets the required volume of the component mold for re-pouring. The pouring hopper in the present device is an object with a smaller volume than the component mold. The amount poured at one time is exactly consistent with the volume of the pouring hopper, which is convenient for measurement. Accurate measurement can be achieved through multiple pourings. For example, if the volume of the pouring hopper is 1 / 50 of the volume of the component mold, the pouring accuracy is ≤2%. The pouring times and conveying speed can be set in advance according to the volume and length of the component mold to achieve coordinated production and pouring accuracy, which also reduces equipment investment, improves production efficiency, and realizes continuous pouring production.

[0013] Based on the above technical features: the casting hopper realizes reciprocating movement between the first limit position and the second limit position in a simple and effective manner.

[0014] As a preferred solution of the novel variable metering pouring device for secondary mixing of concrete described in the present invention, wherein: the pouring hopper is a hollow cylindrical structure with openings at both the top and the bottom, a first material baffle plate is connected to one side of the upper edge of the pouring hopper, the first material baffle plate can move with the pouring hopper, and the first material baffle plate is slidably fitted with the bottom of the mixing tank; a second material baffle plate is arranged on the guide rail, and the second material baffle plate is flush with the lower opening of the pouring hopper;

[0015] When the pouring hopper is located at the first limit position, the first baffle plate is offset from the first discharge port, and the concrete in the secondary mixing mechanism enters the pouring hopper through the first discharge port at the bottom thereof; at the same time, the lower opening of the pouring hopper is blocked by the second baffle plate, and the concrete remains in the space formed by the pouring hopper and the second baffle plate;

[0016] When the pouring hopper is located at the second limit position, the first baffle plate covers the first discharge port to prevent the concrete in the mixing tank from pouring out; at the same time, the second baffle plate is offset from the lower opening of the pouring hopper, and the concrete remaining in the pouring hopper pours out from the lower opening of the pouring hopper.

[0017] Based on the above technical features: when the pouring hopper moves back and forth between the first limit position and the second limit position once, the pouring hopper completes one pouring, and the amount of one pouring is exactly consistent with the volume of the pouring hopper, which is convenient for measurement.

[0018] As a preferred embodiment of the novel variable metering pouring device for secondary mixing of concrete according to the present invention, wherein:

[0019] The hopper driving unit is an electric-controlled cylinder, the output shaft end of the electric-controlled cylinder is fixedly connected with a piston push rod, and the end of the piston push rod is connected to the casting hopper.

[0020] Based on the above technical features: the electric control cylinder can drive the piston push rod to drive the casting hopper to move back and forth left and right.

[0021] The shape and upper and lower openings of the pouring hopper can be in various forms. As a preferred solution of the novel variable metering pouring device for secondary mixing of concrete of the present invention, the lower opening of the pouring hopper is equal to the upper opening.

[0022] Based on the above technical features: the concrete in the pouring hopper can be quickly discharged to improve efficiency.

[0023] As a preferred solution of the novel variable metering pouring device for secondary mixing of concrete described in the present invention, the lower opening of the pouring hopper is slightly larger than the upper opening, and the cross section is slightly trapezoidal.

[0024] Based on the above technical features: concrete in the pouring hopper is not easy to accumulate on the side wall, and it is easier to unload.

[0025] As a preferred solution of the novel variable metering pouring device for secondary concrete mixing of the present invention, wherein: the output shaft end of the reduction motor is fixedly connected to a blade stirrer, and the blade stirrers are arranged in parallel in one or more groups.

[0026] Based on the above technical features: the double-station blade agitator can slowly and evenly stir the concrete in the mixing tank to prevent the initial setting of the concrete.

[0027] As a preferred solution of the novel variable metering casting device for secondary mixing of concrete described in the present invention, the size of the first discharge port is slightly smaller than the size of the casting hopper, and the size of the component mold in the width direction is slightly larger than the size of the casting hopper in the width direction.

[0028] Based on the above technical features: the concrete in the mixing tank can quickly fill the pouring hopper, the concrete in the pouring hopper can quickly pour out into the component mold, and the concrete will not overflow.

[0029] As a preferred solution of the novel variable metering pouring device for secondary mixing of concrete described in the present invention, the conveying unit is a conveyor belt, and the travel speed of the conveyor belt is adapted to the reciprocating motion speed of the pouring hopper, so that when the component mold placed on the conveyor belt passes through the mixing tank, the concrete just fills the component mold through the pouring hopper.

[0030] Based on the above technical features: by controlling the reciprocating speed of the pouring hopper and the traveling speed of the conveyor belt, the component mold can be just filled with concrete during the moving process, thereby achieving the purpose of non-stop continuous production.

[0031] On the other hand, the present invention also provides a variable metering pouring method for secondary mixing of concrete, using the variable metering pouring device for secondary mixing of concrete, the method comprising:

[0032] S1. The mixing tank stirs the concrete to prevent the initial setting of the concrete;

[0033] S2, the hopper driving unit of the movable pouring hopper mechanism drives the pouring hopper to reach the first limit position, and the mixed concrete in the mixing tank is discharged into the space formed by the pouring hopper and the second baffle plate through the first discharge port at the bottom of the mixing tank;

[0034] S3, after the pouring hopper is filled with concrete, the hopper driving unit drives the pouring hopper to the second limit position; at this time, the first baffle plate covers the first discharge port, and the concrete no longer flows out of the mixing tank; at the same time, the second baffle plate is staggered from the pouring hopper, and the concrete flows out of the pouring hopper into the component mold located below it;

[0035] S4, repeating steps S2 and S3, the concrete is continuously transferred from the mixing tank to the pouring hopper and then to the component mold, and the component mold moves forward with the conveying unit until the concrete pouring in the component mold is completed;

[0036] The pouring of component molds of different volumes is adjusted by changing the pouring times of the pouring hopper.

[0037] Based on the above technical features: the number of round trips (casting times) required for the casting hopper to move between the first limit and the second limit for each component mold can be calculated according to the multiple relationship between the component mold and the casting hopper, so that component molds of different volumes can use the same set of the device of the present invention, and the casting error can be controlled within a certain range.

[0038] The beneficial effect of the present invention is that this application can use a set of devices to achieve the metered casting of components of different volumes. If the volume of the component mold changes, it is only necessary to set the pouring times of the appropriate pouring hopper according to the volume of the component, and there is no need to replace it with a pouring hopper that meets the required volume of the component mold for re-pouring. The pouring hopper in this device is an object with a smaller volume than the component mold. The amount poured at one time is exactly consistent with the volume of the pouring hopper, which is convenient for metering. Accurate metering can be achieved through multiple pourings. For example, if the volume of the pouring hopper is 1 / 50 of the volume of the component mold, the pouring accuracy is ≤2%. The pouring times and conveying speed can be set in advance according to the volume and length of the component mold to achieve coordinated production and pouring accuracy, thereby reducing equipment investment, improving production efficiency, and achieving continuous casting production.

DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0049] Example 1

[0050] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a variable metering pouring device for secondary mixing of concrete, comprising:

[0051] The secondary stirring mechanism 200 includes a stirring tank 201 and a reduction motor 202 installed on the stirring tank 201;

[0052] A movable pouring hopper mechanism 300 is arranged at the lower part of the secondary mixing mechanism 200; the movable pouring hopper mechanism 300 includes a pouring hopper 303 and a hopper driving unit for driving the pouring hopper 303 to move back and forth, the pouring hopper 303 has a first limit position and a second limit position, when the pouring hopper 303 is located at the first limit position, the concrete in the secondary mixing mechanism 200 enters the pouring hopper 303 through the first discharge port 201a at the bottom thereof; when the pouring hopper 303 is located at the second limit position, the concrete in the pouring hopper 303 is discharged through the bottom thereof;

[0053] The conveying unit 102 is arranged at the lower part of the movable pouring hopper mechanism 300 , and a component mold 103 is placed on the upper part of the conveying unit 102 for receiving concrete from the pouring hopper 303 .

[0054] In summary: the present application can use a set of devices to achieve the metered casting of components of different volumes. If the volume of the component mold 104 changes, it is only necessary to set the appropriate number of castings of the casting hopper 303 according to the volume of the component, and there is no need to replace it with a casting hopper 303 that meets the required volume of the component mold 104 for re-casting. The casting hopper 303 in the present device is an object with a smaller volume than the component mold 104. The amount of casting at one time is exactly consistent with the volume of the casting hopper 303, which is convenient for metering. Accurate metering can be achieved through multiple castings. For example, if the volume of the casting hopper 303 is 1 / 50 of the volume of the component mold 104, the casting accuracy is ≤2%. The number of castings and the conveying speed can be set in advance according to the volume and length of the component mold 104 to achieve coordinated production and casting accuracy, thereby reducing equipment investment, improving production efficiency, and achieving continuous casting production.

[0055] Example 2

[0056] Reference Figure 2-4 , which is the second embodiment of the present invention, which is different from the first embodiment in that it provides a more specific implementation method:

[0057] The mixing tank 201 is fixed to the upper end of the support frame 101 , and a first discharge port 201 a corresponding to the inlet of the pouring hopper 303 is provided at the bottom of the mixing tank 201 , and the first discharge port 201 a is located at a first limit position.

[0058] Preferably, the lower opening of the pouring hopper 303 is slightly larger than the upper opening (slightly trapezoidal in cross section), so that the concrete in the pouring hopper 303 can be quickly discharged and is not easily accumulated on the side wall.

[0059] Preferably, Figure 4 As shown, the size of the first discharge port is slightly smaller than the size of the casting hopper 303, and the size of the component mold 103 in the width direction is slightly larger than the size of the casting hopper 303 in the width direction. This design allows the concrete in the mixing tank to quickly fill the casting hopper, and the concrete in the casting hopper can be quickly poured into the component mold without the concrete overflowing, greatly improving efficiency.

[0060] The output shaft end of the reduction motor 202 is fixedly connected with a blade stirrer 203. Two groups of blade stirrers 203 are arranged in parallel. The double-station blade stirrers 203 can slowly and evenly stir the concrete in the mixing tank 201 to prevent the initial setting of the concrete.

[0061] Example 3

[0062] Reference Figure 2-3 , which is the third embodiment of the present invention, and is different from the previous two embodiments in that: the hopper driving unit adopts an electric control cylinder 302; the output shaft end of the electric control cylinder 302 is fixedly connected with a piston push rod 302a, the end of the piston push rod 302a is connected to the casting hopper 303, and the feeding end of the casting hopper 303 is connected to the unloading end of the mixing tank 201, and the electric control cylinder 302 can drive the piston push rod 302a to drive the casting hopper (303) to reciprocate between the first limit position and the second limit position.

[0063] Specifically, a first material baffle plate 306 is fixedly connected to the upper end of one side of the pouring hopper 303, and a second material baffle plate 309 is provided on the inner lower bottom surface of the guide rail 307, and the second material baffle plate 309 is flush with the lower opening of the pouring hopper 303. This design can facilitate the pouring hopper 303 to slide in and out of the second material baffle plate 309 (correspondingly, the second material baffle plate 309 can cover or stagger the lower opening of the pouring hopper 303).

[0064] A control box 400 is installed on the outside of the support carrier 101. The control box 400 is electrically connected to the conveying unit 102. The control box 400 can set the pouring times and the conveying speed of the component mold 103 according to the volume and length of the component mold 103 to achieve coordinated production.

[0065] When in use, when the pouring hopper 303 moves to the first limit position on the left, the first baffle plate 306 is separated from the discharge port of the mixing tank 201, and the concrete in the mixing tank 201 can fall into the pouring hopper 303, while the lower opening of the pouring hopper 303 is blocked by the second baffle plate 309, so that the concrete can fill the pouring hopper 303. Afterwards, when the pouring hopper 303 moves to the second limit position on the right, the first baffle plate 306 moves with the pouring hopper 303 to block the discharge port of the mixing tank 201, and the lower opening of the pouring hopper 303 simultaneously leaves the second baffle plate 309, and the concrete in the pouring hopper 303 can fall into the component mold 103, completing one pouring, and the amount of one pouring is exactly consistent with the volume of the pouring hopper 303, which is convenient for measurement.

[0066] The pouring hopper 303 reciprocates once between the first limit position and the second limit position to complete the pouring amount of the pouring hopper 303. For component molds 103 of different volumes, the number of reciprocating movements of the pouring hopper 303 is controlled according to the multiple relationship between the volume and the pouring hopper 303, so that the total amount of concrete pouring can be controlled, and the pouring of the component mold 103 can be completed while ensuring the set accuracy.

[0072] S4, repeating steps S2 and S3, the concrete is continuously transferred from the mixing tank 201 to the pouring hopper 303 and then to the component mold 103, while the component mold 103 moves forward with the conveying unit 102 until the pouring of concrete in the component mold 103 is completed.

[0073] The present invention can use a set of devices to achieve the metered casting of components of different volumes. If the volume of the component mold changes, it is only necessary to set the pouring times of the appropriate pouring hopper according to the volume of the component. There is no need to replace it with a pouring hopper that meets the required volume of the component mold for re-pouring. The amount of one pouring is exactly consistent with the volume of the pouring hopper, which is convenient for metering. The pouring times and conveying speed can be set in advance according to the volume and length of the component mold to achieve coordinated production and pouring accuracy, which also reduces equipment investment, improves production efficiency, and realizes continuous casting production.
