Technical Field
[0001] This utility model belongs to the technical field of concrete mixers, specifically relating to a concrete mixer for plaza construction. Background Technology
[0002] Plaza construction refers to the construction of a plaza, which requires the use of concrete. The concrete needs to be mixed before it can be used, usually by a concrete mixer. Existing concrete mixers are the equipment used for mixing concrete during plaza construction. In existing concrete mixers, after the feed hopper is filled, the material enters the conveying pipe and is then rotated by the main screw conveyor inside the conveying pipe to enter the mixing tank for mixing. When the material is conveyed after entering the conveying pipe, it contains relatively hard materials, which makes it difficult to protect the inside of the conveying pipe from wear. Furthermore, when conveying hard materials, they are prone to contact and compression with the inside of the conveying pipe, causing deformation and even damage over time. This affects the effectiveness of the concrete mixer in protecting the inside of the conveying pipe during plaza construction. Therefore, this utility model proposes a concrete mixer for plaza construction. Utility Model Content
[0003] The purpose of this utility model is to provide a concrete mixer for plaza construction, in order to solve the problems mentioned in the background art, where, when the concrete mixer is used, after the material is fed into the inside of the conveying pipe, the material inside is mixed with hard materials, which makes it difficult to protect the inside of the conveying pipe from wear, and the hard materials are easily squeezed and contacted by the inside of the conveying pipe when conveying, causing deformation, and even damage over time.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a concrete mixer for plaza construction, comprising a main frame, a mixing tank fixedly installed on the upper surface of the main frame, a feeding conveying pipe installed at one end of the mixing tank via a bearing, a feeding box installed on the upper surface of the feeding conveying pipe via a fixing frame, a discharge port fixed at the other end of the mixing tank, an anti-deformation protection mechanism provided inside the feeding conveying pipe, and an anti-blockage and unblocking mechanism provided at the top of one side of the feeding box; The anti-deformation protection mechanism includes a wear-resistant protection component disposed on the inner surface of the feed conveying pipe.

Detailed Implementation
[0014] 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.
[0015] Please see Figures 1 to 6 This utility model provides a technical solution: a concrete mixer for square construction, including a main frame 101, a mixing tank 102 fixedly installed on the upper surface of the main frame 101, a feeding conveying pipe 104 installed at one end of the mixing tank 102 through a bearing, a feeding box 105 installed on the upper surface of the feeding conveying pipe 104 through a fixed frame, and a discharge port 103 fixed at the other end of the mixing tank 102. The feed conveying pipe 104 is equipped with a screw conveyor installed inside via a servo motor. A main drive reduction motor 106 is fixed on one side of the upper surface of the main frame 101. A drive gear 107 is fixed at the end of the output shaft of the main drive reduction motor 106. A driven gear ring 108 that meshes with the drive gear 107 is welded to the outer surface of the mixing tank 102. Control rings 109 are welded to both ends of the mixing tank 102. A rotating groove matching the control ring 109 is provided on the upper surface of the main frame 101. A protective plate 1021 is fixedly installed on the outer surface of the mixing tank 102. An electric controller is fixed on the front surface of the main frame 101. The servo motor, the main drive reduction motor 106, the auxiliary drive reduction motor 1055, and the forward and reverse reduction motor 1056 are all electrically connected to the electric controller via wires. An anti-deformation protection mechanism is provided inside the feed conveying pipe 104. An anti-blockage and unblocking mechanism is provided at the top of one side of the feed box 105. The anti-deformation protection mechanism includes a wear-resistant protection component installed on the inner surface of the feed conveying pipe 104. A snap-fit installation component is provided between the outer surface of the wear-resistant protection component and the inner surface of the feed conveying pipe 104. A rotation fixing component is provided between the end of the wear-resistant protection component and the end of the feed conveying pipe 104. When the feed conveying pipe 104 encounters hard materials and is squeezed during conveying, the anti-deformation protection mechanism directly protects the inside of the feed conveying pipe 104, making it less likely to be squeezed, deformed, or damaged.
[0016] To facilitate wear protection of the feed conveying pipe 104 using a wear-resistant protection component, in this embodiment, preferably, the wear-resistant protection component includes a protective sleeve 1041 fitted inside the feed conveying pipe 104. A limiting disc 1042 is integrally provided at the end of the protective sleeve 1041, and a limiting groove 1044 is formed at the edge of the end of the feed conveying pipe 104. The internal structure of the limiting disc 1042 matches that of the limiting groove 1044. After the protective sleeve 1041 is snapped into place inside the feed conveying pipe 104, the limiting disc 1042 is closed within the limiting groove 1044, completely installing the protective sleeve 1041, thus facilitating installation and use.
[0017] In order to facilitate the snap-fit installation of the protective sleeve 1041 by means of the snap-fit installation assembly, in this embodiment, preferably, the snap-fit installation assembly includes a snap-fit plate 1045 integrally disposed at the edge of the inner surface of the feed conveying pipe 104, and the outer surface of the protective sleeve 1041 is provided with snap-fit grooves 1047 that match the snap-fit plate 1045 at equal intervals. The protective sleeve 1041 is installed inside the feed conveying pipe 104 by snapping the snap-fit plate 1045 into the grooves 1047.
[0018] In order to facilitate the locking and fixing of the protective sleeve 1041 after engagement by rotating the fixing assembly, in this embodiment, preferably, the rotating fixing assembly includes a mounting bolt 1043 threaded to the surface of the limiting plate 1042, and the surface of the clamping plate 1045 is provided with an internal threaded hole 1046 that matches the mounting bolt 1043. After the protective sleeve 1041 is engaged and installed, the mounting bolt 1043 can be rotated to insert into the internal threaded hole 1046 to fix the protective sleeve 1041 in place.
[0019] The lifting and unblocking mechanism includes a lifting component located on one side of the feed box 105. A unblocking and mixing component is located on one side of the lifting component at the top of the feed box 105, and supporting and sliding components are located on both sides of the lifting component. When there is too much material or the material is clumped together during the mixing and stirring process, the lifting and unblocking mechanism can move down into the feed box 105 to break up and unblock the blockage, making it less prone to clogging.
[0020] To facilitate the lifting and adjustment of the main conveyor 1053 via the lifting assembly and to allow for operation according to usage, in this embodiment, preferably, the lifting assembly includes a column 1052 welded and fixed to one side of the feed box 105. A lead screw 1054 rotates inside the column 1052. A forward / reverse geared motor 1056 is fixedly installed at the top of the lead screw 1054 on the upper surface of the column 1052. A movable plate 1051 is provided on the outer surface of the lead screw 1054. When too much material is fed into the feed box 105 or when clumps of material enter, the forward / reverse geared motor 1056 drives the lead screw 1054 to rotate. The rotation of the lead screw 1054 drives the movable plate 1051 to move. The movable plate 1051 then rotates and breaks up the main conveyor 1053 embedded inside the feed box 105 for conveying. Alternatively, when the feed box 105 is not in use, the main conveyor 1053 can also be left unused, depending on the usage.
[0021] To facilitate unblocking of materials in the feed hopper 105 when there is a large amount of material or when the material is clumped together, and to ensure effective feeding without clogging, in this embodiment, preferably, the unblocking and mixing component includes an auxiliary drive reduction motor 1055 fixedly mounted on the upper surface of the moving plate 1051 by fixing bolts. The end of the auxiliary drive reduction motor 1055 is fixedly mounted with a main conveyor 1053 by fixing bolts. The bottom end of the main conveyor 1053 extends into the inside of the feed hopper 105. After the main conveyor 1053 is slowly introduced into the inside of the feed hopper 105, the auxiliary drive reduction motor 1055 drives the main conveyor 1053 to rotate, mixing, dispersing, and conveying the material inside the feed hopper 105, thus preventing clogging.
[0022] In order to facilitate the stable movement and adjustment of the movable plate 1051 by means of the supporting sliding assembly, in this embodiment, preferably, the supporting sliding assembly includes control slide grooves 1057 formed on both sides of the column 1052, and control support plates 1058 are welded to both sides of the lower surface of the movable plate 1051. The ends of the control support plates 1058 are slidably connected to the inside of the control slide grooves 1057, so that the movable plate 1051 can drive the control support plates 1058 to slide within the control slide grooves 1057 when moving, thus making the operation more stable.
[0023] In this utility model, the auxiliary drive geared motor 1055 is model number 5GN-180K, and the forward and reverse geared motor 1056 is model number 5GU5KB.
[0024] The working principle and usage process of this utility model: When using this type of concrete mixer for square construction, the main frame 101 is first placed on the square construction site through contact with the ground. After being placed stably, the upper surface is protected by the protective plate 1021 to prevent it from being affected by the drive. After the material is fed into the feed box 105, it enters the feed conveying pipe 104. The servo motor drives the main screw conveyor to rotate inside the feed conveying pipe 104 to transport the material into the mixing tank 102. The main drive reduction motor 106 drives the drive gear 107 to rotate and mesh with the surface of the driven gear ring 108 to drive the mixing tank 102 to rotate. When the mixing tank 102 rotates, the control ring 109 is inside the rotation groove to stabilize the rotation, thereby stabilizing and mixing the material inside the mixing tank 102. Before use, the protective sleeve 1041 is installed inside the feed conveying pipe 104 by engaging the clamping plate 1045 with the clamping groove 1047 until the limiting plate 1042 is limited inside the limiting groove 1044, completely closing the protective sleeve 1041. Then, the mounting bolt 1043 is rotated again to be embedded inside the internal threaded hole 1046 for fixed installation, thereby fixing the protective sleeve 1041 inside the feed conveying pipe 104. When the material is conveyed by the main screw conveyor inside the feed conveying pipe 104 and encounters hard material, it is directly squeezed onto the surface of the protective sleeve 1041, which facilitates wear-resistant protection. It is not easily deformed or damaged when subjected to pressure for a long time, thus improving the wear-resistant protection effect of the inside of the feed conveying pipe 104 when the concrete mixer is used for mixing and processing at the square construction site. Finally, when the concrete mixer is in use for feeding, the moving plate 1051 is first moved to its highest position, causing the main conveyor 1053 to disengage from the inside of the feed box 105 and allow raw materials to enter the inside of the feed box 105. When too much raw material enters or clumps form and block the inside, the auxiliary drive reduction motor 1055 drives the main conveyor 1053 to rotate, while the forward and reverse reduction motor 1056 drives the lead screw 1054 to rotate. When the lead screw 1054 rotates, it causes the moving plate 1051 to be positioned inside the column 1052 on the outer surface of the lead screw 1054. The limit movement drives the control support plate 1058 to slide and support inside the control chute 1057, so that the main conveyor 1053 moves down and stably enters the feed box 105 to the position that needs to be cleared. This makes it easier for the main conveyor 1053 to rotate and break up the clumps of material inside and transport them inward. It facilitates the breaking up and transporting of materials without clogging, effectively mixes and processes the materials, and can also be raised and not used when there is no blockage inside, avoiding the impact of the material on the feed. It can be used as needed, improving the convenience of clearing the inside of the feed box 105 when the concrete mixer is used in the construction of the square.
[0025] 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.
