Description

Technical Field

[0001] The invention relates to the technical field of concrete processing, and in particular to a high-precision automatic concrete weighing and mixing system. Background Art

[0002] Concrete weighing and mixing refers to the process of accurately weighing raw materials such as cement, aggregates (such as sand and gravel), water and admixtures, and then mixing them evenly through mixing equipment during the concrete production process. The high-precision automated concrete weighing and mixing system is an advanced equipment used in concrete production. It uses automation technology to achieve accurate weighing and efficient mixing of concrete raw materials.

[0003] When the existing concrete weighing and mixing device is used, its mixing form is relatively simple, resulting in poor concrete mixing effect.

[0004] Therefore, we propose a high-precision automated concrete weighing and mixing system that can fully mix the concrete to improve its mixing effect. Summary of the invention

[0005] The purpose of the present invention is to provide a high-precision automated concrete weighing and mixing system to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-precision automated concrete weighing and mixing system, comprising a mixing barrel, a discharge pipe is connected to the bottom of the mixing barrel, support legs are arranged on the outside of the discharge pipe, and a processing assembly is arranged above the support legs, the processing assembly comprises a mixing assembly arranged above the support legs, a cleaning assembly is arranged on the outside of the mixing assembly, and a discharge assembly is arranged above the cleaning assembly.

[0007] Preferably, the mixing assembly includes a mounting plate fixedly mounted on the top surface of the mixing barrel, a motor is fixedly mounted on the top surface of the mounting plate, a rotating tube is fixedly mounted on the output end of the motor, a rotating rod is connected to the outer wall of the rotating tube, a one-way air outlet is connected to the outer wall of the rotating rod, a one-way air inlet is connected to the outer wall of the rotating tube, a sliding groove is provided on the inner wall of the rotating tube, a sliding block is slidingly provided inside the sliding groove, a first wedge-shaped column is fixedly mounted on the outer wall of the sliding block, a spring is fixedly mounted on the top surface of the first wedge-shaped column, and a second wedge-shaped column is provided on the bottom of the first wedge-shaped column.

[0008] Preferably, the cleaning assembly includes a rotating plate fixedly mounted on the outer wall of the rotating tube, a limiting groove is provided at the bottom of the rotating plate, a first magnetic block is fixedly mounted on the inner wall of the limiting groove, a second magnetic block is slidably arranged inside the limiting groove, and a scraper is fixedly mounted on the outer wall of the second magnetic block.

[0009] Preferably, the unloading assembly includes a third magnetic block fixedly mounted on the top surface of the rotating plate, a feed pipe is connected to the top surface of the mixing barrel, a baffle is slidably mounted inside the feed pipe, a square rod is fixedly mounted on the bottom of the baffle, a fourth magnetic block is fixedly mounted on one end of the square rod away from the baffle, and a fixed plate is slidably mounted on the outer wall of the square rod.

[0010] Preferably, one end of the spring is fixedly mounted to an end of the first wedge-shaped column away from its inclined surface, and one end of the spring away from the first wedge-shaped column is fixedly mounted to the inner wall of the rotating tube, and under the elastic action of the spring, the first wedge-shaped column that is not squeezed is reset and pushed.

[0011] Preferably, the end of the first wedge-shaped column is arranged in an inclined surface, and the end of the second wedge-shaped column is fixedly mounted on the inner bottom surface of the mixing barrel. The first wedge-shaped column is arranged in contact with the inclined surface of the second wedge-shaped column. Under the restriction thereof, when the rotating first wedge-shaped column is squeezed by the inclined surface of the second wedge-shaped column, the first wedge-shaped column slides toward the inside of the rotating tube.

[0012] Preferably, the first magnetic block and the second magnetic block are magnetically attracted to each other, and the scraper is slidably arranged with the inner wall of the mixing barrel. Under the restriction of magnetic attraction, the scraper not subject to centrifugal force is pulled, and when the scraper fits with the inner wall of the mixing barrel, the material attached to the inner wall of the mixing barrel can be cleaned.

[0013] Preferably, the end of the fixed plate is fixedly mounted on the top of the mixing barrel, and the fourth magnetic block and the third magnetic block magnetically repel each other. Under the restriction of magnetic repulsion, the square rod can be pushed to slide inside the fixed plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The high-precision automatic concrete weighing and mixing system is composed of a mixing component. When concrete needs to be mixed, the appropriately prepared raw materials are discharged through the discharge component. At this time, the motor is started, and the rotating tube fixedly installed at its output end rotates accordingly. The rotating rod connected to the outer wall of the rotating rod rotates accordingly, and the rotating rod stirs the materials inside the mixing barrel. When the rotating tube rotates, the slide groove provided on its inner wall drives the slider to rotate accordingly, and the slider drives the first wedge-shaped column to rotate. Since the first wedge-shaped column is in contact and extrusion with the inclined surface of the second wedge-shaped column fixedly installed on the bottom surface of the mixing barrel, under its restriction, the first wedge-shaped column drives the slider to slide inside the rotating tube. Due to the sealed sliding between the first wedge-shaped column and the inside of the rotating tube, under its restriction, the first wedge-shaped column pushes the gas inside the rotating tube, and the rotating tube transports gas to the inside of the rotating rod, and then sprays it out through the one-way air outlet, so as to blow and mix the concrete inside the mixing barrel. When the first wedge-shaped column is no longer squeezed by the second wedge-shaped column, the first wedge-shaped column is pushed downward and reset under the elastic action of the spring, and the first wedge-shaped column pumps the gas inside the rotating tube again, and the air is introduced through the one-way air inlet connected to the outer wall of the rotating tube. This structure can mix the concrete by rotating the rotating rod, and blow and stir the raw materials through the one-way air outlet of the jet, so as to improve the concrete mixing effect.

[0015] 2. The high-precision automatic concrete weighing and mixing system is composed of a cleaning component as one of its components. When concrete is mixed, the inner wall of the mixing barrel is prone to adhere to materials and needs to be cleaned. At this time, when the motor speed is adjusted to the maximum, the rotating tube drives the rotating plate to rotate accordingly, and the scraper slidingly arranged at the bottom of the limit groove is subject to increased centrifugal force, and the scraper is swung toward the inner wall of the mixing barrel, so that the scraper contacts the inner wall of the mixing barrel to clean the materials adhered to the inner wall of the mixing barrel. When the mixing is completed, the motor no longer drives the rotating tube to rotate, and the scraper is not affected by the centrifugal force. Under the restriction of the magnetic attraction between the second magnetic block and the first magnetic block, the scraper is pulled toward the rotating tube, so that the second magnetic block contacts and collides with the first magnetic block. Under its restriction, the scraper vibrates to shake off the materials adhered to the outer wall of the scraper.

[0016] 3. The high-precision automatic concrete weighing and mixing system is composed of a material discharge component. When the concrete needs to be mixed, the prepared material is added into the feed pipe. At this time, the motor is started to drive the rotating pipe and the rotating plate to rotate. When the third magnetic block fixedly installed on the top surface of the rotating plate is aligned with the fourth magnetic block, the square rod is pushed upward under the restriction of magnetic repulsion, and the square rod pushes the baffle to place the baffle at the width of the feed pipe. At this time, the baffle no longer blocks the material on its top, and the material is discharged. This structure can discharge the material quantitatively to avoid adding too much material into the mixing barrel at the same time, resulting in poor mixing uniformity.

DETAILED DESCRIPTION

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0027] Embodiment 1: A preferred embodiment of a high-precision automated concrete weighing and mixing system provided by the present invention is as follows: Figures 1 to 8 Shown: A high-precision automated concrete weighing and mixing system, comprising a mixing barrel 1; A discharge pipe 2 is provided at the bottom of the mixing barrel 1; Support legs 3 are provided on the outside of the discharge pipe 2; And a processing component 4 is arranged above the supporting leg 3, the processing component 4 includes a mixing component 41 arranged above the supporting leg 3, the mixing component 41 includes a mounting plate 411 fixedly mounted on the top surface of the mixing barrel 1, a motor 412 is fixedly mounted on the top surface of the mounting plate 411, a rotating tube 413 is fixedly mounted on the output end of the motor 412, a rotating rod 414 is connected to the outer wall of the rotating tube 413, a one-way air outlet 415 is connected to the outer wall of the rotating rod 414, a one-way air inlet 416 is connected to the outer wall of the rotating tube 413, a sliding groove 417 is opened on the inner wall of the rotating tube 413, a sliding block 418 is slidably arranged inside the sliding groove 417, a first wedge column 419 is fixedly mounted on the outer wall of the sliding block 418, a spring 420 is fixedly mounted on the top surface of the first wedge column 419, and a second wedge column 421 is arranged at the bottom of the first wedge column 419.

[0028] In this embodiment, when it is necessary to mix concrete, the properly prepared raw materials are discharged through the discharge assembly 44, and the motor 412 is started at this time, and the rotating tube 413 fixedly installed at its output end rotates accordingly, and the rotating rod 414 connected to the outer wall of the rotating rod 414 rotates accordingly, and the rotating rod 414 stirs the materials inside the mixing barrel 1. When the rotating tube 413 rotates, the slide groove 417 provided on its inner wall drives the slider 418 to rotate accordingly, and the slider 418 drives the first wedge-shaped column 419 to rotate. Since the first wedge-shaped column 419 is in contact and extruded with the inclined surface of the second wedge-shaped column 421 fixedly installed on the bottom surface of the mixing barrel 1, under its restriction, the first wedge-shaped column 419 drives the slider 418 to slide inside the rotating tube 413. Since the first wedge-shaped column 419 and the rotating tube 4 13 internal seal slides, under its restriction, the first wedge column 419 pushes the internal gas of the rotating tube 413, the rotating tube 413 transports gas to the inside of the rotating rod 414, and then sprays it out through the one-way air outlet 415, so as to blow and mix the concrete inside the mixing barrel 1. When the first wedge column 419 is no longer squeezed by the second wedge column 421, the first wedge column 419 is pushed downward and reset under the elastic action of the spring 420, and the first wedge column 419 pumps the internal gas of the rotating tube 413 again, and the air is taken in through the one-way air inlet 416 connected to the outer wall of the rotating tube 413. This structure can mix the concrete through the rotating rod 414, and blow and flip the raw materials through the one-way air outlet 415 of the jet, so as to improve the concrete mixing effect.

[0029] Example 2: Based on Example 1, a preferred embodiment of a high-precision automated concrete weighing and mixing system provided by the present invention is as follows: Figures 1 to 8 As shown: the cleaning component 43 includes a rotating plate 431 fixedly mounted on the outer wall of the rotating tube 413, a limiting groove 432 is provided at the bottom of the rotating plate 431, a first magnetic block 433 is fixedly mounted on the inner wall of the limiting groove 432, a second magnetic block 434 is slidably arranged inside the limiting groove 432, and a scraper 435 is fixedly mounted on the outer wall of the second magnetic block 434.

[0030] In this embodiment, when concrete is mixed, materials are easily attached to the inner wall of the mixing barrel 1 and need to be cleaned. At this time, when the speed of the motor 412 is adjusted to the maximum, the rotating tube 413 drives the rotating plate 431 to rotate accordingly, and the scraper 435 slidingly arranged at the bottom of the limiting groove 432 is increased by the centrifugal force, and the scraper 435 is swung toward the inner wall of the mixing barrel 1, so that the scraper 435 contacts the inner wall of the mixing barrel 1 to clean the materials attached to the inner wall of the mixing barrel 1. When the mixing is completed, the motor 412 no longer drives the rotating tube 413 to rotate, and the scraper 435 is not affected by the centrifugal force. Under the restriction of the magnetic attraction between the second magnetic block 434 and the first magnetic block 433, the scraper 435 is pulled toward the rotating tube 413, so that the second magnetic block 434 contacts and collides with the first magnetic block 433. Under its restriction, the scraper 435 vibrates to shake off the materials attached to the outer wall of the scraper 435.

[0031] Embodiment 3: Based on Embodiment 1, a preferred embodiment of a high-precision automatic concrete weighing and mixing system provided by the present invention is as follows: Figures 1 to 8 As shown: the unloading component 44 includes a third magnetic block 441 fixedly mounted on the top surface of the rotating plate 431, a feeding pipe 442 is connected to the top surface of the mixing barrel 1, a baffle 443 is slidably arranged inside the feeding pipe 442, a square rod 444 is fixedly mounted on the bottom of the baffle 443, a fourth magnetic block 445 is fixedly mounted on one end of the square rod 444 away from the baffle 443, and a fixing plate 446 is slidably arranged on the outer wall of the square rod 444.

[0032] In this embodiment, when it is necessary to mix the concrete, the prepared material is added to the feed pipe 442. At this time, the motor 412 is started, which drives the rotating pipe 413 and the rotating plate 431 to rotate. When the third magnetic block 441 fixedly installed on the top surface of the rotating plate 431 is aligned with the fourth magnetic block 445, under the restriction of magnetic repulsion, the square rod 444 is pushed upward, and the square rod 444 pushes the baffle 443 to place the baffle 443 at the wide part of the feed pipe 442. At this time, the baffle 443 no longer blocks the material on its top, and the material is discharged. This structure can discharge the material quantitatively to avoid adding too much material into the mixing barrel 1 at the same time, resulting in poor mixing uniformity.

[0033] Furthermore, one end of the spring 420 is fixedly installed with the end of the first wedge-shaped column 419 away from its inclined surface, and the end of the spring 420 away from the first wedge-shaped column 419 is fixedly installed with the inner wall of the rotating tube 413. Under the elastic action of the spring 420, the first wedge-shaped column 419 that is not squeezed is pushed to reset. The end of the first wedge-shaped column 419 is arranged with an inclined surface, and the end of the second wedge-shaped column 421 is fixedly installed with the inner bottom surface of the mixing barrel 1. The first wedge-shaped column 419 and the second wedge-shaped column 421 are arranged in contact with each other on the inclined surface. Under their restriction, when the rotating first wedge-shaped column 419 is squeezed by the inclined surface of the second wedge-shaped column 421, the first wedge-shaped column 419 slides toward the inside of the rotating tube 413.

[0034] Furthermore, the first magnetic block 433 and the second magnetic block 434 are magnetically attracted to each other, and the scraper 435 is slidably arranged on the inner wall of the mixing barrel 1. Under the restriction of magnetic attraction, the scraper 435 that is not subject to centrifugal force is pulled. When the scraper 435 fits against the inner wall of the mixing barrel 1, the material attached to the inner wall of the mixing barrel 1 can be cleaned.

[0035] In addition, the end of the fixed plate 446 is fixedly installed on the top of the mixing barrel 1, and the fourth magnetic block 445 and the third magnetic block 441 magnetically repel each other. Under the restriction of magnetic repulsion, the square rod 444 can be pushed to make the square rod 444 slide inside the fixed plate 446.

[0036] The above are only exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention. It should also be noted that the various components of the present invention are not limited to the above-mentioned overall application.
