[0002] In road maintenance projects, damaged road surfaces need to be repaired. Therefore, mixing devices are usually used on construction sites to mix road maintenance materials. Existing mixing devices for road maintenance materials have the problem of inconvenient material discharge, because the discharge port is mostly located at the bottom of the mixing device, resulting in small discharge volume at one time and easy spillage of the discharged mixed material.

[0003] A search revealed that prior art CN210674967U discloses a road maintenance material mixing device, including a base plate, a fixed base, and a collection bucket. The fixed base is fixedly connected to one side of the upper surface of the base plate, and the collection bucket is movably connected to the other side of the upper surface of the base plate. A support column is fixedly connected to the lower surface of the base plate. A top cover is movably connected to the upper surface of the collection bucket via bolts. A mixing cylinder is movably connected to the inner wall of the fixed base. A fixing plate is movably connected to the upper surface of the fixed base via bolts. A motor housing is fixedly connected to the upper surface of the mixing cylinder. This road maintenance material mixing device, through the coordinated arrangement of the base plate, collection bucket, support column, and top cover, provides a height for the device via the support column, facilitating the placement of the collection bucket. The top cover prevents the mixed material from spilling out of the collection bucket due to vibration during the feeding process, thus avoiding inconvenience to workers.

[0004] However, the above equipment has the following problem when used: the equipment cannot mix materials at different temperatures, which reduces the mixing efficiency of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a road maintenance material mixing device, which aims to solve the problem that existing equipment cannot mix materials at different temperatures, thus reducing the mixing efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides a road maintenance material mixing device, including a mixing tank, with movable wheels installed at the bottom of the support of the mixing tank, a water jacket structure inside the mixing tank, and a heating pipe and a temperature sensor installed on the outside of the water jacket structure.

[0007] It also includes auxiliary components;

[0008] The auxiliary components include an electric heater, a drain valve, a discharge valve, a filter seat, a positioning plate, a plug-in block, a connecting seat, a feeding component, and a mixing component. Multiple electric heaters are detachably installed on the mixing tank. The drain valve communicates with the water jacket structure and is located at the bottom of the mixing tank. The discharge valve communicates with a storage chamber inside the mixing tank that is isolated from the water jacket structure and is located below the discharge port at the bottom of the mixing tank. The filter seat is installed at the bottom of the discharge valve. Two positioning plates are spaced apart, each with a first and second filter screen installed via snap rings. The plug-in block enables spaced engagement. The filter hole diameter of the second filter screen is smaller than that of the first filter screen. The connecting seat is detachably connected to the filter seat and is located below the filter seat. It is connected to an external extraction mechanism via a pipe. The feeding component is located on the mixing tank, and the mixing component is located inside the mixing tank.

[0009] The feeding component includes a feeding pipe and a water injection pipe. The feeding pipe is connected to the storage bin inside the mixing tank, and the water injection pipe is connected to the water jacket structure.

[0010] The mixing component includes a stirring motor and a stirring frame. The stirring motor is detachably mounted on a removable sealing cover on the top of the mixing tank. The top connecting shaft of the stirring frame is connected to the output shaft of the stirring motor via a coupling.

[0011] The heating ends of the multiple electric heaters located inside the mixing tank have a U-shaped structure.

[0012] The road maintenance material mixing device further includes an isolation component, which includes a first isolation cover and a second isolation cover. The first isolation cover and the second isolation cover are respectively provided with a group of vent holes and are respectively threaded onto the feeding pipe and the water injection pipe.

[0013] This utility model discloses a road maintenance material mixing device. During processing, the maintenance liquid is put into a mixing tank, and the mixing components are controlled to stir and mix it. Furthermore, during mixing, the maintenance liquid inside the storage chamber is heated by an electric heater, thereby enabling the maintenance liquid to be stirred and mixed at different temperatures. Then, the water in the water jacket structure is heated by a heating pipe. After the electric heater stops heating for a certain period of time, the water in the water jacket structure is heated to the required temperature by the heating pipe.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, where Figure 1 This is a schematic diagram of the overall structure of a road maintenance material mixing device. Figure 2 This is a structural diagram of the stirring rack 118. Figure 3 This is a structural schematic diagram of filter holder 108. Figure 4This is a schematic diagram of the positioning plate 109. This utility model provides a road maintenance material mixing device: it includes a mixing tank 101 and auxiliary components. The mixing tank 101 has a water jacket structure 102 inside, and a heating pipe 103 and a temperature sensor 104 are arranged outside the water jacket structure 102. The auxiliary components include an electric heater 105, a drain valve 106, a discharge valve 107, a filter seat 108, a positioning plate 109, a plug-in block 110, a connecting seat 111, a feeding component, and a mixing component. The feeding component includes a feeding pipe 115 and a water injection pipe 116. The mixing component includes a mixing motor 117 and a mixing frame 118. The aforementioned solution solves the problem that existing equipment cannot mix materials at different temperatures, which reduces the mixing efficiency of the equipment. It is understood that the aforementioned solution allows materials to be mixed at different temperatures.

[0024] In this embodiment, the bottom of the support of the mixing tank 101 may be equipped with casters for moving the device. The extraction mechanism in this application adopts the structure disclosed in CN207838837U for extracting and conveying the curing liquid. The corresponding water distribution pipe and nozzle may also be installed on the cover plate on the top of the device.

[0025] The mixing tank 101 is equipped with a water jacket structure 102 inside, and a heating tube 103 and a temperature sensor 104 are arranged on the outside of the water jacket structure 102. The water jacket structure 102 is used to store heat-insulating water, which can be discharged after being opened by the drain valve 106. The heating tube 103 and the temperature sensor 104 are fixed by bolts, and the corresponding heating or detection parts extend into the water jacket structure 102 and are in contact with the water. The heating tube 103 is electrically heated.

[0026] Multiple electric heaters 105 are detachably installed on the mixing tank 101. The drain valve 106 is connected to the water jacket structure 102 and is located at the bottom of the mixing tank 101. The discharge valve 107 is connected to the storage chamber inside the mixing tank 101 that is isolated from the water jacket structure 102 and is located below the discharge port at the bottom of the mixing tank 101. The filter seat 108 is installed at the bottom of the discharge valve 107. Two positioning plates 109 are spaced apart and are respectively limited by snap rings 114 to install a first filter screen 112 and a second filter screen 113. The insertion block 110 is used to achieve spaced cooperation. The filter hole diameter of the second filter screen 113 is smaller than that of the first filter screen 112. The connecting seat 111 is detachably connected to the filter seat 108 and is located below the filter seat 108. It is connected to an external extraction mechanism through a pipe. The feeding component is located on the mixing tank 101, and the mixing component is located inside the mixing tank 101. Multiple electric heaters 105 are used to heat the curing liquid. The discharge valve 107 is used to discharge the liquid after opening. The top connecting flange of the filter seat 108 is connected to the bottom flange of the discharge valve 107 by a screw and nut. The filter seat 108 has an internal mounting cavity to facilitate the sliding installation of the two positioning plates 109. The positioning plates 109 have stepped mounting cavities for installing the first filter screen 112 and the second filter screen 113. The first filter screen 112 and the second filter screen 113 are respectively limited by snap rings 114. The positioning plates 109 are spaced apart by four plug-in blocks 110. The plug-in block 110 has a semi-circular head on the side near the second filter screen 113 and a rectangular end on the other side.

[0027] Secondly, the feeding pipe 115 is connected to the storage hopper inside the mixing tank 101; the water injection pipe 116 is connected to the water jacket structure 102. The feeding pipe 115 and the water injection pipe 116 are welded and fixed respectively.

[0028] Then, the stirring motor 117 is detached and installed on the removable sealing cover on the top of the mixing tank 101; the top connecting shaft of the stirring frame 118 is connected to the output shaft of the stirring motor 117 via a coupling. The stirring motor 117 is fixed with bolts, and its output shaft is connected to the connecting shaft of the stirring frame 118 via a coupling. When working, the stirring motor 117 can drive the stirring frame 118 to rotate, which can mix the curing liquid.

[0029] Finally, the heating ends of the plurality of electric heaters 105 located inside the mixing tank 101 are U-shaped. This structure facilitates the heating of the internal curing liquid. At the same time, a temperature sensor 104 can be installed on one side of the electric heater 105. The detection part of the temperature sensor 104 is extended and extends into the mixing tank 101 to detect the internal temperature.

[0030] When using this invention to solve the problem that existing equipment cannot mix materials at different temperatures, thus reducing the mixing efficiency of the equipment, the curing liquid is fed into the mixing tank 101 through the feeding pipe 115 during processing. The mixing motor 117 drives the mixing frame 118 to rotate for mixing. Furthermore, during mixing, the curing liquid inside the storage chamber is heated by the electric heater 105, thereby enabling the curing liquid to be mixed at different temperatures. Then, water pre-injected into the water jacket structure 102 is heated through the heating pipe 103. Heating is performed, and after the electric heater 105 heats for a certain period of time, heating is stopped. Then, the water in the water jacket structure 102 is heated to the required temperature through the heating pipe 103. A heat preservation structure can be set on the outside of the storage chamber to keep the curing liquid warm. Then, the discharge valve 107 is opened, and the material is filtered through the filter seat 108, the first filter screen 112 and the second filter screen 113. The filtered material is then connected to the extraction mechanism through the connecting seat 111 and the pipe. This solves the problem that existing equipment cannot allow materials to be stirred at different temperatures, which would reduce the stirring efficiency of the equipment.

[0032] like Figure 5 As shown, where Figure 5 This is a schematic diagram of the overall structure of a road maintenance material mixing device. Based on the first embodiment, this utility model provides a road maintenance material mixing device, which further includes an isolation component, including a first isolation cover 201 and a second isolation cover 202.

[0033] The first isolation cover 201 and the second isolation cover 202 are each provided with a vent hole assembly, which is threaded onto the feeding pipe 115 and the water injection pipe 116, respectively. The feeding pipe 115 and the water injection pipe 116 are each provided with an external threaded mounting end, facilitating direct installation of the first isolation cover 201 and the second isolation cover 202. The vent hole assembly on the first isolation cover 201 and the second isolation cover 202 allows for ventilation.

[0034] In this embodiment, by providing the first isolation cover 201 and the second isolation cover 202, they can be installed after adding materials or water to reduce the entry of external impurities into the interior.
