Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a feeding device for a concrete mixer. Background Art

[0002] A concrete mixer is a professional equipment used to mix raw materials such as cement, sand and gravel aggregates, water and possible admixtures to prepare concrete. According to their working principles and structural forms, concrete mixers are mainly divided into the following types: self-falling mixers, forced mixers, planetary mixers, drum mixers, etc.

[0003] During the mixing process, the blades exert strong shearing and friction on the materials, which can effectively destroy the agglomeration between cement particles and break the initial hydrate film coating on the surface of cement particles, so that the cement particles can better hydrate. The automated and continuous production method improves the efficiency of concrete preparation, reduces manual labor intensity, and shortens the construction period. In short, concrete mixers are key equipment in the concrete production process. Choosing a suitable mixer is crucial to ensuring the quality of concrete and construction progress.

[0004] In order to ensure the mixing effect during the mixing process of concrete, it is often necessary to add cement and stone particles gradually. When the stone particles are put into the mixer for mixing, due to the high speed of the mixer during the mixing process, the stone particles may collide with the mixing blades and fly out, which may cause safety hazards to the feeding personnel. In addition, the amount of stone particles added cannot be controlled during the manual feeding process, and uneven feeding is prone to occur. Utility Model Content

DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] Combined with Figure 1-3 As shown, a feeding device of a concrete mixer comprises a device base 1, a feeding box 2 is fixedly connected to the upper end of the device base 1, a storage chamber 3 is arranged in the feeding box 2, a plurality of moving seats 14 are stacked at the lower end of the device base 1, a moving wheel 15 is rotatably connected in the moving seat 14, a moving handle 16 is arranged on one side of the device base 1, an observation window 17 is arranged on the feeding box 2, and the device base 1 can be pushed and moved by pushing the moving handle 16, so that the feeding box 2 is moved to the top of the mixer to start feeding.

[0021] Specifically, a telescopic slot 4 is connected to one side of the device base 1, and a feeding mechanism 5 is provided in the telescopic slot 4. The feeding mechanism 5 includes a feeding barrel 7 slidably connected to the telescopic slot 4, and a sealing cover 8 is provided on one side of the feeding barrel 7. The feeding barrel 7 is a top-down through-body structure. A driving assembly 6 for driving the feeding mechanism 5 to telescopically move is provided in the telescopic slot 4. The driving assembly 6 includes a telescopic cylinder 9 and a telescopic rod 10. The telescopic cylinder 9 is fixedly connected to the device base 1, and the telescopic end of the telescopic cylinder 9 is connected to the telescopic rod 10. One side of the telescopic rod 10 is fixedly connected to the feeding barrel 7. The telescopic end of the telescopic cylinder 9 drives the telescopic rod 10 to telescopically move, and the telescopic rod 10 drives the feeding barrel 7 to slide in the telescopic slot 4. When the feeding barrel 7 extends out of the telescopic slot 4, since the feeding barrel 7 is a through-body structure, the stone particles in the feeding barrel 7 will fall into the mixer.

[0022] Specifically, a feeding port 11 communicating with the storage chamber 3 is provided at the upper end of the feeding box 2, a discharge port 12 communicating with the feeding barrel 7 is provided in the storage chamber 3, and a guide block 13 is provided on one side of the discharge port 12 in the storage chamber 3. The guide block 13 can guide the stone particles poured into the storage chamber 3 to the discharge port 12, and finally fall into the feeding barrel 7 from the discharge port 12.

[0023] During the specific use of the utility model, the device base 1 is first pushed to the side of the mixer. When adding materials is needed, the required stone particles are first poured into the feeding port 11 at the upper end of the feeding box 2, and the stone particles fall into the storage chamber 3 through the feeding port 11. The guide block 13 in the storage chamber 3 guides the stone particles falling into the storage chamber 3 into the discharge port 12, and the stone particles are sent to the feeding barrel 7 through the discharge port 12 and fill the feeding barrel 7. The telescopic cylinder 9 in the device base 1 is started, and the telescopic rod 10 at the telescopic end of the telescopic cylinder 9 is extended, and the telescopic rod 10 drives the feeding barrel 7 to move in the telescopic groove 4. When the feeding barrel 7 moves out of the telescopic groove 4, since the feeding barrel 7 is a through-body structure, the stone particles in the feeding barrel 7 will fall into the mixer, and there is no need to At this time, the blocking cover 8 on one side of the feeding barrel 7 will block the discharge port 12 at the lower end of the feeding box 2 to prevent the material in the storage chamber 3 from falling, and then the telescopic rod 10 will shrink. During the shrinkage process, the bottom end of the telescopic slot 4 will cover the bottom of the feeding barrel 7. When the feeding barrel 7 moves below the discharge port 12, the material in the discharge chamber 3 can refill the feeding barrel 7. In this way, the telescopic rod 10 drives the feeding barrel 7 to reciprocate. Since the capacity of the feeding barrel 7 is fixed, quantitative feeding can be achieved to prevent too much stone from being dumped at one time, which makes it difficult for the mixer to mix. When adding materials to the mixer, there is no need for the feeding personnel to stand next to the mixer and manually add materials, which can prevent the staff from being injured by the stones bursting out of the mixer opening.

[0024] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
