DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1. Please refer to Figures 1 - 5 , the present invention provides a technical solution: a concrete material mixer, including a bottom plate 1 and a cylinder 117. A mixing tank body 101 is fixedly connected to the center of the top of the bottom plate 1. Two fixing plates 102 are fixedly connected to the outer surface of the mixing tank body 101. A threaded lead screw 106 is movably connected to both sides of the inner wall of one of the fixing plates 102. A first motor 103 is fixedly installed at the center of the bottom of one of the fixing plates 102. The output end of the first motor 103 is fixedly connected to one end of the threaded lead screw 106. Limit columns 107 are fixedly connected to both sides of the inner wall of the other fixing plate 102. A sealing door 109 is threadedly connected to the outer surface of the threaded lead screw 106. A second motor 104 is fixedly installed at the center of the top of the sealing door 109. The output end of the second motor 104 is fixedly connected to a main shaft 105. The bottom end of the main shaft 105 is fixedly connected to a hollow column 115. Two plug pins 113 are movably embedded in the inner wall of the hollow column 115. One end of each of the two plug pins 113 is fixedly connected to a pulling plate 112. A spring 114 is fixedly connected to one side of the outer surface of the pulling plate 112. The inside of the sealing door 109 is movably sleeved on the outer surface of the limit column 107. One end of the spring 114 is fixedly connected to the outer surface of the hollow column 115. The other ends of the two plug pins 113 are both fixedly connected to a pop-up block 116. Two insertion holes 118 are formed in the outer surface of the cylinder 117. The inside of the two insertion holes 118 is movably connected to the outer surface of the two pop-up blocks 116. A plurality of stirring plates 2 are fixedly connected to the outer surface of the cylinder 117.

[0033] In this embodiment, first, after the concrete mixing operation is completed, the staff turns on the external power supply of the first motor 103 and starts the first motor 103 using the controller. The output end of the first motor 103 begins to drive the threaded lead screw 106 to rotate forward. As the threaded lead screw 106 continues to rotate forward, the sealing door 109 located on the surface of the threaded lead screw 106 starts to rise vertically. At this time, the limit post 107 limits the sealing door 109. Since the sealing door 109 is overall heavy, this method is convenient for quickly opening the sealing door 109, thereby facilitating the removal of the cylinder 117. Then, the staff manually pulls two extraction plates 112. When the extraction plates 112 are pulled out, the pin posts 113 located on one side of the extraction plates 112 are also quickly pulled out. At this time, the two pop-up blocks 116 inside the jacks 118 on the surface of the unwashed cylinder 117 are pulled out. Then, the staff quickly takes out the cylinder 117 and conducts a detailed cleaning. Then, the cleaned cylinder 117 is quickly placed vertically in the hollow column 115. As the surface of the cylinder 117 moves vertically upward, the staff has previously aligned the two jacks 118 with the two pop-up blocks 116 and then moved the cylinder 117. When the two pop-up blocks 116 pass through the two jacks 118, the pop-up blocks 116 are quickly bounced into the jacks 118 by the elastic force of the spring 114, thereby quickly installing the cylinder 117. Thus, it is possible to quickly disassemble the mixing rod, facilitate its disassembly for detailed cleaning, and improve the disassembly and assembly efficiency of the concrete mixing rod.

[0034] Embodiment 2, as Figures 1 - 5 shown, two cross bars 201 are fixedly connected to the outer surface of the cylinder 117. One end of each of the two cross bars 201 is fixedly connected to a scraping plate 202. Support legs 110 are fixedly connected to the four corners at the bottom of the bottom plate 1, and a discharge hopper 111 is fixedly connected to the center of the bottom of the bottom plate 1.

[0035] In this embodiment, subsequently, the staff turns on the first motor 103 again and uses the controller to drive the threaded lead screw 106 to rotate in reverse by the first motor 103. While the threaded lead screw 106 rotates in reverse, the sealing door 109 moves vertically downward and is completely closed on the top of the mixing tank body 101. Then, the first motor 103 is turned off, the external power supply of the second motor 104 is turned on, and the second motor 104 is started using the controller. The output end of the second motor 104 begins to drive the main shaft 105 and the cylinder 117 as a whole to rotate. While the cylinder 117 rotates, the two cross bars 201 and the two scraping plates 202 start to rotate around the cylinder 117 as the center and remove the concrete particles adhering to the inner wall of the mixing tank body 101. Subsequently, the removed concrete is washed into the discharge hopper 111 by pouring in clean water, and the concrete particles are discharged using the discharge hopper 111. Thus, it is possible to clean the concrete remaining on the inner wall of the tank, improving the practicality of the concrete material mixer.

[0036] Working principle: When in use, first, after the concrete mixing operation is completed, the staff turns on the external power supply of the first motor 103 and starts the first motor 103 using the controller. The output end of the first motor 103 begins to drive the threaded screw rod 106 to rotate forward. As the threaded screw rod 106 continues to rotate forward, the sealing door 109 located on the surface of the threaded screw rod 106 starts to rise vertically. At this time, the limit post 107 limits the sealing door 109. Since the sealing door 109 is overall heavy, this method is convenient for quickly opening the sealing door 109, thus facilitating the disassembly of the cylinder 117. Then, the staff manually pulls two extraction plates 112. When the extraction plates 112 are extracted, the pin columns 113 on one side of the extraction plates 112 are also quickly extracted. At this time, the two pop-up blocks 116 inside the jacks 118 on the surface of the unwashed cylinder 117 are extracted. Then, the staff quickly takes out the cylinder 117 and conducts a detailed cleaning. Then, the cleaned cylinder 117 is quickly placed vertically in the hollow column 115. As the surface of the cylinder 117 moves vertically upward, the staff has previously aligned the two jacks 118 with the two pop-up blocks 116 and then moved the cylinder 117. When the two pop-up blocks 116 pass through the two jacks 118, the pop-up blocks 116 are quickly ejected into the jacks 118 by the elastic force of the spring 114, thereby quickly installing the cylinder 117. This achieves the ability to quickly disassemble the mixing rod, facilitating disassembly for detailed cleaning, and improving the disassembly and assembly efficiency of the concrete mixing rod. Subsequently, the staff turns on the first motor 103 again and uses the controller to make the first motor 103 drive the threaded screw rod 106 to reverse. While the threaded screw rod 106 is reversing, the sealing door 109 moves vertically downward and completely closes on the top of the mixing tank body 101. Then, the first motor 103 is turned off, and the external power supply of the second motor 104 is turned on. The second motor 104 is started using the controller. The output end of the second motor 104 begins to drive the main shaft 105 and the cylinder 117 as a whole to rotate. While the cylinder 117 is rotating, the two cross bars 201 and the two scraping plates 202 start to rotate around the cylinder 117 as the center and remove the concrete particles adhering to the inner wall of the mixing tank body 101. Subsequently, clear water is poured in to wash the removed concrete into the feed hopper 111, and the concrete particles are discharged using the feed hopper 111, thereby achieving the cleaning of the concrete remaining on the inner wall of the tank and improving the practicability of the concrete material mixer.

[0037] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
