Description

Technical Field

[0001] This utility model belongs to the technical field of raw material proportioning devices, specifically relating to a concrete raw material proportioning device. Background Technology

[0002] Concrete raw materials are the materials used to process and produce concrete. Concrete raw materials need to be mixed in proportion during processing. This is usually done by a raw material proportioning device, and the existing raw material proportioning device is the equipment used for proportioning concrete raw materials. Existing raw material proportioning devices directly feed raw materials into the mixing cylinder during concrete mixing. When additives are injected into the cylinder and fed in slowly, vibrations during operation can cause sedimentation, resulting in a concentrated mix initially and a thinner mix later. This uneven mixing reduces the overall mixing efficiency and hinders the device's ability to ensure uniform mixing within the mixing cylinder. Therefore, this invention proposes a concrete raw material proportioning device. Utility Model Content

[0003] The purpose of this utility model is to provide a concrete raw material proportioning device to solve the problem mentioned in the background art that when the raw material proportioning device is used to mix and proportion concrete, the additives are inside the batching cylinder and the feeding is slow. At this time, the vibration generated by the operation of the equipment can easily cause the internal additives to settle, resulting in a relatively concentrated mixture when it first enters and a relatively thin mixture in subsequent batches, leading to uneven proportioning operations and reduced proportioning effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a concrete raw material proportioning device, comprising a mixing box, with supports welded to both sides of the mixing box, a feeding box welded to the top of the mixing box, three batching cylinders fixed to the top of the feeding box, a control valve provided at the bottom of the batching cylinders, a stirring mechanism provided inside the batching cylinders, the stirring mechanism including a lifting and mounting assembly provided on the rear surface of the feeding box, a stirring component provided inside the lifting and mounting assembly located inside the batching cylinders, a driving component provided at the top of the stirring component located inside the lifting and mounting assembly, and a protective component provided on the outer surface of the stirring component.

[0005] Preferably, a sand and gravel inlet is fixed on one side of the feeding box, an agitator is rotated inside the mixing box via a bearing, a servo motor is fixedly installed at the end of the agitator on the lower surface of the mixing box, a discharge port is provided on one side of the bottom of the mixing box, and a control valve is provided inside the discharge port.

[0006] Preferably, the lifting and mounting assembly includes an electric cylinder that is bolted to the rear surface of the feeding box, and a top frame is bolted to the top of the electric cylinder.

[0007] Preferably, the stirring assembly includes a main shaft mounted on the top of the top frame via bearings, and the bottom end extends into the interior of the mixing cylinder, with stirring shafts welded and fixed at equal intervals to the bottom edge of the main shaft.

[0008] Preferably, the drive assembly includes a gear fixedly installed at the top of the main shaft inside the top frame, and the two gears mesh with each other. A geared motor is fixedly installed at the middle position of the top of the top frame, and the end of the output shaft of the geared motor is fixed to the surface of the intermediate gear by bolts.

[0009] Preferably, the two main shafts are connected to the interior of the top frame via two gears.

[0010] Preferably, the protective assembly includes a protective cover mounted on the outer surface of the top end of the main shaft via a bearing, wherein a sealing ring is fixed on the inner surface of the protective cover, and the inner surface of the sealing ring is in close contact with the outer surface of the top end of the dispensing cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By designing a mixing mechanism, after the additive is filled into the mixing cylinder, the top frame moves down and the protective cover is sealed to the top of the mixing cylinder with a sealing ring. The main shaft and the mixing shaft are embedded inside the mixing cylinder. The three main shafts and the mixing shaft rotate, and the mixing shaft rotates and mixes inside the mixing cylinder. This makes it less likely for the additive to precipitate inside the mixing cylinder, and it is evenly mixed into the internal proportioning. It is less likely to cause different proportions of the proportioning concentration, and it improves the convenience of the proportioning device for uniform mixing inside the mixing cylinder when proportioning concrete raw materials.

[0014] Please see Figures 1 to 6 This utility model provides a technical solution: a concrete raw material proportioning device, including a mixing box 102, with supports 101 welded to both sides of the mixing box 102, a feeding box 103 welded to the top of the mixing box 102, three batching cylinders 105 fixed to the top of the feeding box 103, a control valve provided at the bottom of the batching cylinders 105, a sand and gravel inlet 104 fixed to one side of the feeding box 103, a stirrer 106 rotating inside the mixing box 102 via bearings, a servo motor fixedly installed at the end of the stirrer 106 on the lower surface of the mixing box 102, a discharge port 107 provided on one side of the bottom of the mixing box 102, a control valve provided inside the discharge port 107, and a controller provided on the front surface of the mixing box 102; The mixing cylinder 105 is equipped with a stirring mechanism, which includes a lifting and mounting assembly located on the rear surface of the feeding box 103. The mixing assembly is located inside the mixing cylinder 105, and a driving assembly is located at the top of the mixing assembly inside the lifting and mounting assembly. A protective assembly is provided on the outer surface of the mixing assembly. When the additive is injected into the mixing cylinder 105, the stirring mechanism can rotate the mixing cylinder 105 to uniformly mix the additives. After uniform mixing, the additives are injected and used in proportion.

[0015] In order to facilitate the installation and adjustment of the main shaft 1055 by means of the lifting and mounting assembly, in this embodiment, preferably, the lifting and mounting assembly includes an electric cylinder 1051 that is fixedly mounted on the rear surface of the feed box 103 by bolts, and a top frame 1052 is fixedly mounted on the top of the electric cylinder 1051 by bolts, so that the electric cylinder 1051 can drive the top frame 1052 to drive the main shaft 1055 to be lifted and adjusted.

[0016] In order to facilitate the stirring of the additives inside the mixing cylinder 105 by means of a stirring assembly, to prevent sedimentation, and to ensure uniform mixing and proportioning, in this embodiment, preferably, the stirring assembly includes a main shaft 1055 mounted on the top of the top frame 1052 via a bearing, and the bottom end of the main shaft 1055 extends into the interior of the mixing cylinder 105. Stirring shafts 1056 are welded and fixed at equal intervals to the bottom edge of the main shaft 1055, so that the main shaft 1055 and the stirring shaft 1056 can be rotated inside the mixing cylinder 105 to stir and mix the additives inside.

[0017] In order to facilitate the simultaneous rotation of the three main shafts 1055 for mixing and processing via the drive assembly, in this embodiment, preferably, the drive assembly includes gears 1057 fixedly installed at the top of the main shaft 1055 inside the top frame 1052, with two gears 1057 meshing with each other. A geared motor 1053 is fixedly installed at the middle position of the top of the top of the top frame 1052. The end of the output shaft of the geared motor 1053 is fixed to the surface of the middle gear 1057 by bolts. When the geared motor 1053 is driven, it can drive the three gears 1057 to mesh and rotate, and drive the main shaft 1055 and the stirring shaft 1056 to rotate and mix for processing.

[0018] In order to facilitate the protection and stirring of the top of the mixing cylinder 105 by means of a protective component, in this embodiment, preferably, the protective component includes a protective cover 1054 mounted on the outer surface of the top of the main shaft 1055 by a bearing. A sealing ring 1058 is fixed on the inner surface of the protective cover 1054, and the inner surface of the sealing ring 1058 is in close contact with the outer surface of the top of the mixing cylinder 105. When the protective cover 1054 is closed on the top of the mixing cylinder 105, it can be sealed by the sealing ring 1058, which facilitates protection during stirring and mixing and prevents splashing to the outside.

[0019] In this utility model, the geared motor 1053, the servo motor, and the electric cylinder 1051 are all electrically connected to the controller. The controller controls the start and stop, which is existing technology and will not be described in detail. The model of the electric cylinder 1051 is fC30bPzn.

[0020] The working principle and usage process of this utility model are as follows: When using this concrete raw material proportioning device, firstly, the bottom end of the support 101 contacts the ground to stably place the proportioning device at the usage position. After the proportioning device is fixedly installed at the usage position, the top frame 1052 and the main shaft 1055 are moved to the top by the electric cylinder 1051. The batching cylinder 105 is opened and the additives to be added are injected into the batching cylinder 105. An appropriate amount of additives is injected into the feeding box 103 and observed by the scale. Then, sand and gravel are introduced into the feeding box 103 through the sand and gravel inlet 104 and introduced into the mixing box 102. The servo motor at the bottom drives the agitator 106 to rotate and mix the incoming raw materials. After mixing, the discharge port 107 is opened to discharge the raw materials. Then, when in use, after the additive is filled into the mixing cylinder 105, the electric cylinder 1051 moves again to drive the top frame 1052 to move down, thereby sealing the protective cover 1054 at the top of the mixing cylinder 105 through the sealing ring 1058. This allows the main shaft 1055 and the stirring shaft 1056 to be embedded inside the mixing cylinder 105. When the additive injected into the mixing cylinder 105 causes sedimentation, the gear 1053 drives the gear 1057 to rotate. The rotation between the two gears 1057 drives the three main shafts 1055 and the stirring shaft 1056 to rotate, and the stirring shaft 1056 rotates inside the mixing cylinder 105 to perform stirring. This makes it less likely for the additive inside the mixing cylinder 105 to precipitate, and ensures that it is evenly mixed into the internal proportioning, preventing differences in the proportioning concentration. During the stirring process, the protective cover 1054 protects the top of the mixing cylinder 105 from splashing into the outside, improving the convenience of the proportioning device in uniformly mixing the contents of the mixing cylinder 105 when proportioning concrete raw materials.

[0021] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
