Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a turnover and folding feeding hopper. Background Art

[0002] The mine mobile fire prevention and control grouting device is used at the working face and goaf of the coal mine where there is a risk of spontaneous combustion of coal. It is a grouting device with fire prevention and control function for injecting slurry substances such as mud, fly ash slurry, lime slurry and chemical gel (or higher viscosity liquids containing mechanical impurities and solid particle concentrates) with water as the conveying medium. The whole set of device includes an automatic stirring and pulping machine, a pressurized slurry conveying machine, a pressure and flow regulating device and an electric control device.

[0003] The automatic stirring and pulping machine is used to prepare the slurry. When preparing the slurry, it is necessary to use auxiliary feeding equipment to convey materials such as soil into the stirring equipment. The auxiliary feeding equipment needs to be provided with a feeding hopper. The feeding hopper protrudes from the auxiliary feeding equipment and cannot be retracted, resulting in a large occupied space of the overall auxiliary feeding equipment.

[0024] The following will describe various exemplary embodiments, features and aspects of the present application in detail with reference to the drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0025] The special term "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not have to be construed as superior to or better than other embodiments.

[0026] In addition, for better illustration of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without certain specific details. In some instances, methods, means, and components well-known to those skilled in the art are not described in detail to highlight the gist of the present application.

[0027] Please refer to Figures 1 - 3 , in the embodiment of the present utility model, a flip-foldable feeding hopper is applied to a mine mobile fire prevention and extinguishing grouting device or other feeding structures. Taking the mine mobile fire prevention and extinguishing grouting device as an example, the mine mobile fire prevention and extinguishing grouting device includes a lifting and feeding mechanism 4 and a pulp making mechanism 3. The lifting and feeding mechanism 4 and the pulp making mechanism 3 are both installed on a vehicle frame 1, and wheels 2 are installed at the bottom of the vehicle frame 1 to facilitate the movement of the mine mobile fire prevention and extinguishing grouting device.

[0028] Specifically, the flip-foldable feeding hopper includes a folding feeding hopper 5. The folding feeding hopper 5 includes a bottom plate 502 hinged to the lifting and feeding mechanism 4; two symmetrically arranged side plates 501, which are respectively hinged to the side ends of the bottom plate 502, and when the side plates 501 rotate relative to the bottom plate 502 to 90° or 270°, they can be detachably connected to a connecting member 503 fixed on the lifting and feeding mechanism 4.

[0029] In this embodiment, when feeding is not required, the connecting member 503 is separated from the side plate 501, and then the side plate 501 is rotated 90° or 270° and then attached to the bottom plate 502. Then the bottom plate 502 is rotated upward so that the bottom plate 502 is attached to the lifting and feeding mechanism 4 to reduce the space occupied by the feeding hopper. Especially in a coal mine, it can reduce the space occupied in the coal mine shaft, and has strong practicability.

[0030] Preferably, both the side plate 501 and the bottom plate 502 are made of metal materials to ensure the strength of the side plate 501 and the bottom plate 502 and reduce the possibility of the side plate 501 and the bottom plate 502 cracking or being significantly deformed.

[0031] Furthermore, please refer to Figure 1 , the bottom plate 502 is arranged in a rectangular plate-like structure, and the bottom of the bottom plate 502 is hinged to the lifting and feeding mechanism 4.

[0032] Preferably, the side plate 501 is arranged in a right-angled triangular plate-like structure, and the hypotenuse of the side plate 501 is hinged to the bottom plate 502. When the side plate 501 rotates to a state perpendicular to the bottom plate 502, one right-angled side of the side plate 501 is attached to the lifting and feeding mechanism 4 so that there is no obvious gap between the side plate 501 and the lifting and feeding mechanism 4, thereby eliminating the problem of materials falling out between the side plate 501 and the lifting and feeding mechanism 4.

[0033] Exemplarily, in one embodiment, a first connection hole 5011 is formed on the side plate 501, and a second connection hole 5031 is formed on the connecting member 503. After the axes of the first connection hole 5011 and the second connection hole 5031 are collinear, the side plate 501 and the connecting member 503 can be fixedly penetrated by a pin, so as to realize the position and shape limitation after the feeding hopper is unfolded, and at the same time ensure that the feeding hopper will not fall or spread during the feeding process. Specifically, the pin may include but is not limited to a screw.

[0034] The flip-foldable feeding hopper further includes a limiting member 504 installed on the lifting and feeding mechanism 4. After the side plate 501 is folded to be parallel to the bottom plate 502 and the bottom plate 502 is attached to the lifting and feeding mechanism 4, the limiting member 504 limits the bottom plate 502 and the side plate 501. Exemplarily, in one embodiment, the limiting member 504 includes a long strip-shaped limiting plate rotatably installed on the lifting and feeding mechanism 4.

[0035] After the bottom plate 502 and the side plate 501 are folded, manually rotate the limiting member 504 to a horizontal state, then rotate the bottom plate 502 and the side plate 501 to a state attached to the lifting and feeding mechanism 4, and then turn down the limiting member 504 to achieve limiting and fixing.

[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claims.

[0037] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
