Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, specifically a novel concrete mixing hopper. Background Technology

[0002] Concrete hoppers, also known as tower crane hoppers or mortar hoppers, are used in construction projects to hold cement, concrete, mortar, cement, bricks, steel bars, and tools. This reduces the need for manual labor to move raw materials and steel, thereby lowering the intensity of human labor and alleviating the physical labor of migrant workers.

[0003] For example, Chinese utility model patent (application number: CN219638425U) discloses a concrete hoisting hopper, including a frame, a hopper body, a discharge pipe, an adjusting component, and a flow restricting pipe. The hopper body is set on the frame and has lifting lugs. The discharge pipe is located at the bottom of the hopper body. The diameter of the discharge pipe is smaller than the diameter of the hopper body and is connected to the hopper body. The adjusting component is set on the discharge pipe and is used to control the opening size of the channel inside the discharge pipe. The flow restricting pipe is rotatably set on the side wall of the discharge pipe and slides along the axial direction of the discharge pipe. The flow restricting pipe and the discharge pipe are in a sleeved state, and the diameter gradually decreases from top to bottom when in the sleeved state.

[0004] While this solution can control the discharge of concrete, it cannot mix the concrete inside the hopper. If the concrete dries out after being in the hopper for a long time, it will be difficult to discharge and it is also inconvenient to clean the inner wall of the hopper. If it is not cleaned in time, the concrete will solidify on the inner wall and become difficult to clean.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

Detailed Implementation

[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] See Figures 1 to 4 :

[0026] This utility model provides a novel concrete mixing hopper, including a fixed frame 1 and a hopper device. The fixed frame 1 is provided with a accommodating space 11 for installing the hopper device. Hanging rings 12 are fixedly installed on the four corners of the top of the fixed frame 1 to facilitate handling or lifting.

[0027] The hopper device includes a hopper body 2, a mixing assembly 3 for mixing concrete, a spraying assembly for cleaning, and an opening and closing assembly 5 located at the bottom of the hopper device, all disposed within the hopper body 2. The hopper body 2 includes a first hopper 21 with an upper cylindrical shape and a second hopper 22 with a lower conical shape. For ease of description, the first hopper 21 is positioned at the top, and the second hopper 22 is positioned at the bottom.

[0028] Both the upper and lower ends of the first hopper 21 and the second hopper 22 are open, and the first hopper 21 and the second hopper 22 are integrally formed. The upper end of the first hopper 21 is provided with a top cover 23 for opening and closing the first hopper 21, and the top cover 23 is hinged to the first hopper 21. Specifically, a hinge seat is provided on the first hopper 21, and a hinge shaft is provided at one end of the top cover 23. The opening and closing of the top cover 23 is completed by the hinge shaft matching the hinge seat. A handle 24 is fixedly installed on the top surface of the top cover 23 to facilitate the operator to open and close the top cover 23. It is worth noting that the hinge structure between the top cover 23 and the first hopper 21 is consistent with the hinge structure on the market, which is to hinge and fix one end of the top cover 23 to the first hopper 21, and will not be described in detail here.

[0029] Furthermore, a mixing assembly 3 is rotatably mounted on the first hopper 21 near the second hopper 22. The mixing assembly 3 includes a rotating shaft 31 and a motor 32 that drives the rotating shaft 31 to rotate. The rotating shaft 31 is rotatably mounted inside the first hopper 21. One end of the rotating shaft 31 is abutted against and rotatably mounted on the side wall of the first hopper 21, and the other end passes through the side wall of the first hopper 21 and extends outward to be connected to the motor 32. The motor 32 is mounted on the outer side wall of the first hopper 21. A mixing blade 33 is mounted on the rotating shaft 31 inside the first hopper 21. The motor 32 drives the rotating shaft 31 to rotate inside the first hopper 21, thereby causing the mixing blade 33 to mix the concrete and prevent it from becoming stagnant.

[0030] Furthermore, the top cover 23 has an internal cavity 231, and the spraying assembly includes a water inlet 232 and multiple cleaning pipes 233, both of which are connected to the cavity 231. Specifically, both cleaning pipes 233 are rotatably connected to the bottom of the top cover 23, and the water inlet 232 is fixedly connected to the top of the top cover 23.

[0031] A main nozzle 234 is fixedly installed at the bottom of the cleaning pipe 233, and multiple auxiliary nozzles 235 are equidistantly installed on the outside of the cleaning pipe 233 (in this embodiment, three are evenly distributed on the outside of the cleaning pipe 233 and are all connected to the cleaning pipe 233). The water inlet 232 is connected to an external water pipe, and the water inside the external water pipe will enter the cavity 231 inside the top cover 23, so that the water inside the cavity 231 is sprayed through the main nozzle 234 and the auxiliary nozzles 235 to clean the hopper body 2 and the stirring blades 33.

[0032] Furthermore, a discharge port 25 is fixedly connected to the bottom of the second hopper 22, and a bent pipe 6 is detachably connected to the lower end of the discharge port 25. It is worth noting that in this embodiment, the discharge port 25 and the bent pipe 6 can be fastened together using a conventional clamp structure 7, or conventional threaded connection, snap-fit ​​connection, etc., as long as the bent pipe 6 can be fixed to the discharge port 25. The bent pipe 6 is provided to facilitate the transportation of concrete in the hopper body 2 to the destination when there is insufficient space at the bottom of the fixing frame 1.

[0033] Furthermore, the discharge port 25 is provided with an opening and closing assembly 5 for opening and closing the second hopper 22. Specifically, the opening and closing assembly 5 includes a valve disc 51 disposed in the discharge port 25 and a switch 52 disposed on the outer wall of the second hopper 22. The cross-section of the valve disc 51 is the same as the cross-section of the discharge port 25, and the switch 52 is connected to the valve disc 51 through a connecting shaft 53. By rotating the switch 52, the valve disc 51 is rotated, thereby opening and closing the discharge port 25 to facilitate material discharge.

[0034] It is worth noting that there is another implementation method in this embodiment. When less concrete is required or two different proportions of concrete are required, the valve 51 in this embodiment can be set as two valves, namely a first valve 511 and a second valve 512. The first valve 511 and the second valve 512 are adapted to be set on the discharge port 25, and a first switch 521 and a second switch 522 are respectively provided. By rotating the first switch 521 and the second switch 522, the first valve 511 and the second valve 512 can be controlled to open or close, thereby controlling the material discharge.

[0035] Meanwhile, a partition 26 is detachably installed inside the feed head body 2, and the partition 26 extends to the discharge port 25. The first switch 521 and the first valve 511 control the amount of material discharged on one side of the partition 26, and the second switch 522 and the second valve 521 control the amount of material discharged on the other side of the partition 26. At the same time, the stirring blade 33 is a two-section type, which is respectively set on both sides of the partition 26.

[0036] In this embodiment, the following steps are taken during use: The top cover 23 is opened via handle 24, and the partition 26 divides the interior of the hopper body 2 into two areas. Two different concrete mixes are stored in each area. The top cover 23 is then closed, and the hopper body 2 is hoisted to the desired area using the hanging ring 12. A bend 6 is then attached to the discharge port 25 using clamp 22 to guide the material flow. The motor 32 drives the mixing blades 33 to mix the concrete in both areas, preventing solidification. Depending on the application, the first valve 511 and the second valve 511 can be controlled by rotating different switches 52. 512 is opened or closed inside the discharge port 25 to control the material discharge. After the hopper body 2 is used, a water pipe is connected to the water inlet 232 at the top of the top cover 23. Water flows through the cavity 231 into the two cleaning pipes 233. The two main nozzles 234 at the bottom of the cleaning pipes 233 rinse the two mixing blades 33 directly below to prevent concrete from sticking. Due to the installation angle of the three auxiliary nozzles 235, the cleaning pipes 233 are rotated due to the impact force when water is discharged, causing the three auxiliary nozzles 235 to rotate and rinse, cleaning the two areas inside the hopper body 2.
