Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, specifically to a high-efficiency concrete mixing device. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] Currently, in the production and processing of concrete, multiple raw materials need to be placed in a mixer for mixing. Existing mixers can only mix materials by rotating the mixing rod, and the mixing drum is in a fixed position, resulting in low mixing efficiency.

[0004] As disclosed in Chinese Patent CN215848932U, a high-efficiency concrete mixing device uses a first motor to drive the cylinder and baffle to rotate, and a second motor to drive the rotating rod to rotate, causing the mixing rod and mixing blades to rotate in the opposite direction to the cylinder. This enables rapid mixing of raw materials and effectively solves the problem that existing mixers can only mix materials by rotating the mixing rod, with a fixed mixing drum and low mixing efficiency. Furthermore, the arc-shaped cover plate facilitates the loading and unloading of materials in this high-efficiency concrete mixing device without affecting the rotation of the cylinder.

[0005] However, when the mixing device mixes concrete, the concrete raw materials inside the mixing drum can only be mixed in the longitudinal direction, and the raw materials cannot be mixed with each other quickly in the transverse direction, thus affecting the mixing efficiency of the concrete.

[0006] Therefore, we urgently need to provide a high-efficiency concrete mixing device. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency concrete mixing device to solve the problem mentioned in the background art that the concrete raw materials inside the mixing drum can only be mixed in the longitudinal direction, while the raw materials cannot be quickly mixed with each other in the transverse direction, thus affecting the mixing efficiency of concrete.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency concrete mixing device, comprising a base and a support plate, wherein the support plate is fixedly connected to the left and right ends of the upper side of the base, a support ring is fixedly connected to the upper end of the support plate, a mixing drum for mixing concrete is rotatably connected to the inner side of the support ring, and a mixing mechanism is connected to the inner and outer ends of the mixing drum.

[0009] The stirring mechanism includes limiting rings fixedly connected to the left and right ends of the outer side of the stirring cylinder. A first motor is installed on the left side of the support plate on the upper left side of the base. A gear is fixedly connected to the right end of the output shaft of the first motor. A gear ring is fixedly connected to the left end of the outer side of the stirring cylinder. A spiral plate is fixedly connected to the inner side of the stirring cylinder. A second motor is installed in the middle of the right side of the stirring cylinder. A rotating shaft is fixedly connected to the left end of the output shaft of the second motor. A spiral stirring blade is fixedly connected to the outer side of the rotating shaft. A discharge pipe is fixedly connected to the lower left end of the stirring cylinder. A cap is connected to the left end of the discharge pipe. A feeding unit is connected to the outer end of the stirring cylinder.

[0010] A further improvement is that the feeding unit includes an L-shaped plate fixedly connected to the left side of the support plate on the upper right side of the base, a connecting ring fixedly connected to the upper end of the L-shaped plate, and a feeding hopper fixedly connected to the middle position inside the upper end of the connecting ring.

[0011] A further improvement is that an annular groove is provided at the middle position of the inner side of the support ring, and the outer side of the limiting ring is slidably connected to the inner side of the annular groove, so that when the stirring cylinder rotates inside the support ring, the limiting ring will rotate inside the annular groove.

[0012] A further improvement is that the gear and the gear ring mesh, so that when the first motor is started and its output shaft rotates to drive the gear to rotate, the gear ring can be driven to rotate, thereby causing the stirring drum to rotate.

[0013] A further improvement is that the spiral plates and spiral mixing blades have opposite spiral directions. Thus, when the mixing drum rotates and the spiral mixing blades are rotated by starting the second motor, the spiral plates and spiral mixing blades rotate in opposite directions. This allows the spiral plates to transport the concrete raw materials at the bottom of the inner side of the mixing drum to the left, while the concrete raw materials near the center of the mixing drum are transported to the right by the spiral mixing blades.

[0014] A further improvement is that the outer side of the left end of the discharge pipe is provided with an external thread, and the inner side of the cover is provided with an internal thread. The outer side of the left end of the discharge pipe is threaded to the inner side of the cover. Thus, by rotating the cover to remove it from the outer side of the left end of the discharge pipe, the concrete in the mixing drum can be discharged and collected from the discharge pipe.

[0015] A further improvement is that the outer right end of the mixing drum is slidably connected to the inner side of the connecting ring, and a feeding hole is opened on the upper right side of the mixing drum below the feeding hopper. After the added material is poured into the feeding hopper, when the mixing drum rotates, the feeding hole on its right end rotates to the bottom of the feeding hopper, and the raw material in the feeding hopper will fall into the feeding hole through the lower end of the feeding hopper and then into the interior of the mixing drum.

[0016] In summary, this application discloses a high-efficiency concrete mixing device.

[0017] In this technical solution, when the mixing drum rotates, the second motor is started to make the spiral mixing blades rotate. The spiral plates and spiral mixing blades rotate in opposite directions, which allows the spiral plates to transport the concrete raw materials at the bottom of the mixing drum to the left, while the concrete raw materials near the center of the mixing drum are transported to the right by the spiral mixing blades. This allows the concrete raw materials in the mixing drum to be tumbled longitudinally and mixed laterally, thereby accelerating the concrete mixing rate and making concrete mixing production more efficient.

[0018] Furthermore, when additional raw materials need to be added during the mixing of concrete raw materials, the materials are poured into the feed hopper. As the mixing drum rotates, the feed hole on the right end rotates to the bottom of the feed hopper. The raw materials in the feed hopper fall into the feed hole through the bottom of the feed hopper and then into the interior of the mixing drum. When the feed hole is not located below the feed hopper, the bottom of the feed hopper contacts the outer wall of the mixing drum and is thus sealed. This feeding method allows for the addition of raw materials during the concrete mixing process without shutting down the entire mixing device. The raw materials are simply poured into the feed hopper and added automatically as the mixing drum rotates, thereby further improving the mixing efficiency of the concrete.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution: a high-efficiency concrete mixing device, including a base 1 and a support plate 2. The support plate 2 is fixedly connected to the left and right ends of the upper side of the base 1. A support ring 3 is fixedly connected to the upper end of the support plate 2. A mixing drum 4 for mixing concrete is rotatably connected to the inner side of the support ring 3. A mixing mechanism is connected to the inner and outer ends of the mixing drum 4.

[0026] The stirring mechanism includes limiting rings 501 fixedly connected to the left and right ends of the outer side of the stirring cylinder 4. An annular groove is formed in the middle of the inner side of the support ring 3, and the outer side of the limiting ring 501 is slidably connected to the inner side of the annular groove. Therefore, when the stirring cylinder 4 rotates inside the support ring 3, the limiting ring 501 will rotate inside the annular groove, ensuring that the horizontal position of the stirring cylinder 4 does not change when it rotates inside the support ring 3, thus limiting the movement of the stirring cylinder 4.

[0027] A first motor 502 is installed on the left side of the support plate 2 on the upper left side of the base 1. A gear 503 is fixedly connected to the right end of the output shaft of the first motor 502. A gear ring 504 is fixedly connected to the left side of the outer side of the mixing drum 4. The gear 503 and the gear ring 504 mesh, so that when the output shaft of the first motor 502 is started and rotates, it drives the gear 503 to rotate, which in turn drives the gear ring 504 to rotate, causing the mixing drum 4 to rotate. At the same time, the concrete raw materials inside the mixing drum 4 are tumbled and mixed.

[0028] A spiral plate 505 is fixedly connected to the inner side of the mixing drum 4. A second motor 506 is installed at the middle of the right side of the mixing drum 4. A rotating shaft 507 is fixedly connected to the left end of the output shaft of the second motor 506. A spiral mixing blade 508 is fixedly connected to the outer side of the rotating shaft 507. The spiral direction of the spiral plate 505 and the spiral mixing blade 508 are opposite. Thus, when the mixing drum 4 rotates, the spiral plate 505 and the spiral mixing blade 508 rotate in opposite directions when the second motor 506 is started. This allows the spiral plate 505 to transport the concrete raw materials at the bottom of the inner side of the mixing drum 4 to the left, while the concrete raw materials near the center of the mixing drum 4 are transported to the right by the spiral mixing blade 508. This causes the concrete raw materials in the mixing drum 4 to be tumbled longitudinally and mixed laterally, thereby accelerating the concrete mixing rate and making concrete mixing production more efficient.

[0029] A discharge pipe 509 is fixedly connected to the lower left end of the mixing drum 4. A cover 510 is connected to the left end of the discharge pipe 509. The outer side of the left end of the discharge pipe 509 has an external thread, and the inner side of the cover 510 has an internal thread. The outer side of the left end of the discharge pipe 509 is threaded to the inner side of the cover 510. Thus, after the concrete in the mixing drum 4 is mixed, the concrete in the mixing drum 4 can be discharged and collected from the discharge pipe 509 by rotating the cover 510 and removing it from the outer side of the left end of the discharge pipe 509.

[0030] A feeding unit is connected to the outer end of the mixing drum 4. The feeding unit includes an L-shaped plate 601 fixedly connected to the left side of the support plate 2 on the upper right side of the base 1. A connecting ring 602 is fixedly connected to the upper end of the L-shaped plate 601. A feeding hopper 603 is fixedly connected to the middle position inside the upper end of the connecting ring 602. The outer right end of the mixing drum 4 is slidably connected to the inner side of the connecting ring 602. A feeding hole is opened on the upper right side of the mixing drum 4 below the feeding hopper 603. Therefore, when other raw materials need to be added during the mixing of concrete raw materials, the added materials are poured into the feeding hopper 603. During the rotation of the mixing drum 4... When the feed hole at the right end of the mixing drum 4 rotates to the lower part of the feed hopper 603, the raw materials in the feed hopper 603 will fall into the feed hole through the lower end of the feed hopper 603 and then into the interior of the mixing drum 4. When the feed hole is not located below the feed hopper 603, the lower end of the feed hopper 603 will contact the outer wall of the mixing drum 4 and be sealed. Thus, raw materials can be added during the concrete mixing process through this feeding method without having to shut down the entire mixing device. The raw materials only need to be poured into the feed hopper 603, and they will be added automatically while the mixing drum 4 is rotating, thereby further improving the mixing efficiency of the concrete.

[0031] Working principle: During concrete mixing, the raw materials are first measured, and then fine aggregate, cement, water, and mineral admixtures are poured into the feed hopper 603. The mixture then enters the mixing drum 4 through the feed hole on the right side of the feed hopper 603. Next, the first motor 502 and the second motor 506 are started. The output shaft of the first motor 502 drives the gear 503 to rotate, which in turn drives the gear ring 504 to rotate, causing the mixing drum 4 to rotate and agitate the raw materials in the mixing drum 4. Simultaneously, the spiral plate 505 conveys the concrete raw materials at the bottom inner side of the mixing drum 4 to the left. The output shaft of the second motor 506 drives the rotating shaft 507 and the spiral mixing blades 508 to rotate. The concrete raw materials near the center of the mixing drum 4 are conveyed to the right, so that the concrete raw materials in the mixing drum 4 are mixed in both the horizontal and vertical directions until the raw materials inside the mixing drum 4 are mixed into mortar. Then, coarse aggregate is added to the feed hopper 603. When the feed hole opened at the right end of the mixing drum 4 is rotated to the bottom of the feed hopper 603, the coarse aggregate enters the mixing drum 4 from the feed hole for mixing. After the coarse aggregate is mixed evenly, the admixture is added to the feed hopper 603 and the mixing continues evenly until the concrete is completely mixed and formed. Then, the cover 510 is rotated to remove it from the outside of the left end of the discharge pipe 509, so that the concrete in the mixing drum 4 is discharged from the discharge pipe 509 and collected.
