Description

Technical Field

[0001] The utility model relates to the technical field of sand and stone mixing, in particular to a sand and stone mixing device used in the construction industry. Background Art

[0002] Building materials machinery refers to various production and mixing machines used in the production of building materials such as cement, cement products, glass, glass fiber, building ceramics and bricks and tiles. The building materials machinery industry mainly includes the raw materials industry, building materials production technology research and development industry and machinery manufacturing industry for producing building materials products. Sand and gravel are indispensable materials in building materials. When mixing sand and gravel materials, a mixing device for sand and gravel is needed to mix them.

[0003] The existing sand and gravel mixing device is easy to cause the separation of sand and stone during use, and the mixing effect is poor. Since the stirring paddle of the ordinary sand and gravel mixing device cannot stir the sand and gravel at the bottom, it will cause uneven mixing and low mixing efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problems and to provide a sand and stone mixing device for the construction industry.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes an outer shell of a sand and stone mixing device, an inner cylinder is fixedly arranged inside the outer shell, a plurality of discharge ports are provided on the outer wall of the inner cylinder, a spiral stirring paddle is rotatably arranged inside the inner cylinder, a motor used in conjunction with the spiral stirring paddle is installed on the outer wall of the outer shell, a transmission box is fixedly arranged on the upper end of the outer shell, a discharge pipe is arranged on the lower end of the outer shell located inside the inner cylinder, and a feed port is arranged on the upper end of the outer shell.

[0006] Furthermore, the shell includes a conical top cover, an outer cylinder and a bottom plate, and the bottom plate is located between the outer cylinder and the inner cylinder and is inclined.

[0007] Furthermore, there is a gap between the lowermost end of the outer wall of the inner cylinder and the bottom plate, and there is a gap between the upper end of the inner cylinder and the top cover.

[0008] Furthermore, the spiral stirring paddle comprises a main shaft, the outer wall of the main shaft is fixedly provided with spiral blades, the upper end of the main shaft is fixedly provided with a connecting shaft, and the lower end of the main shaft is rotatably connected to the bottom plate.

[0009] Furthermore, the motor output shaft and the connecting shaft are rotatably connected to the transmission box respectively, and the motor output shaft and the connecting shaft are connected via a bevel gear.

[0010] Furthermore, the upper end of the transmission box is arranged in an arc shape.

[0011] Furthermore, the bottom of the spiral blade is in contact with the surface of the bottom plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, a worker puts the material into the outer shell through the feed port, and the motor starts working at the same time. The motor output shaft drives the connecting shaft to rotate through the bevel gear, and the connecting shaft drives the spiral stirring paddle to rotate. Then the spiral stirring paddle pushes the sand and gravel at the bottom of the outer shell to the upper end of the inner cylinder. Since a discharge port is provided on the outer wall of the inner cylinder, some sand and gravel enters the position between the inner cylinder and the outer shell from the discharge port, thereby making the stirring more uniform and more efficient.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-4A sand and stone mixing device for the construction industry comprises a shell 1 of the sand and stone mixing device, an inner cylinder 2 is fixedly arranged inside the shell 1, a plurality of discharge ports 201 are provided on the outer wall of the inner cylinder 2, a spiral stirring paddle 3 is rotatably arranged inside the inner cylinder 2, a motor used in conjunction with the spiral stirring paddle 3 is installed on the outer wall of the shell 1, a transmission box 5 is fixedly arranged on the upper end of the shell 1, a discharge pipe 102 is arranged inside the inner cylinder 2 at the lower end of the shell 1, a feed port is arranged on the upper end of the shell 1, a motor output shaft and a connecting shaft are rotatably connected to the transmission box 5 respectively, and the motor output shaft and The connecting shafts are connected by bevel gears, and the upper end of the transmission box 5 is set in an arc shape. In actual application, the staff puts the material into the shell 1 through the feed port, and the motor starts working at the same time. The motor output shaft drives the connecting shaft to rotate through the bevel gear, and the connecting shaft drives the spiral stirring paddle 3 to rotate. Then the spiral stirring paddle 3 pushes the sand and gravel at the bottom of the shell 1 to the upper end of the inner cylinder 2. Since the outer wall of the inner cylinder 2 is provided with a discharge port 201, some sand and gravel enter the position between the inner cylinder 2 and the shell 1 from the discharge port 201, so that the mixing is more uniform and more efficient.

[0022] The outer shell 1 includes a top cover with a conical top end, an outer cylinder and a bottom plate 101. The bottom plate 101 is located between the outer cylinder and the inner cylinder 2 and is inclined. There is a gap between the bottom end of the outer wall of the inner cylinder 2 and the bottom plate 101, and there is a gap between the upper end of the inner cylinder 2 and the top cover. The bottom of the spiral blade 302 is in contact with the surface of the bottom plate 101. In actual applications, since the bottom plate 101 is located between the outer cylinder and the inner cylinder 2 and is inclined, and there is a gap between the bottom end of the outer wall of the inner cylinder 2 and the bottom plate 101, the sand and gravel between the inner cylinder 2 and the outer shell 1 will enter the inner cylinder 2, and the sand and gravel will finally be pushed to the upper end of the inner cylinder 2 by the spiral stirring paddle 3.

[0023] The spiral stirring paddle 3 includes a main shaft 301, the outer wall of the main shaft 301 is fixedly provided with spiral blades 302, the upper end of the main shaft 301 is fixedly provided with a connecting shaft, and the lower end of the main shaft 301 is rotatably connected to the bottom plate 101. In actual application, due to the setting of the spiral blades 302, the forward rotation of the spiral stirring paddle 3 pushes the sand and gravel to the upper end of the inner tube 2, and the reverse rotation pushes the sand and gravel downward, so that the sand and gravel are discharged from the discharge pipe 102.

[0024] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
