Description

Technical Field

[0001] The utility model relates to the technical field of concrete batching, in particular to a batching device with an anti-blocking structure. Background Art

[0002] Concrete, commonly known as cement, is commonly used in construction. Concrete is one of the most important civil engineering materials in contemporary times. It is made of cementitious materials, granular aggregates (also known as aggregates), water, and admixtures and additives added when necessary in a certain proportion.

[0003] There is a concrete batching device (its authorization announcement number is: CN218196043U). It starts two first servo motors to drive two push plates to rotate 90 degrees to a vertical state, so that the batching ports at the bottom of the two storage boxes are opened, so that the concrete raw materials in the two storage boxes can enter the batching boxes synchronously through the guide tube and the mixing pipe. Then, the spiral conveying blades rotate to stir and mix the materials in the batching boxes, thereby improving the batching and mixing effect.

[0004] However, this type of concrete batching device has some shortcomings during actual use: during the batching process, the two concrete raw materials are prone to blockage at the tapered mouth between the conduit and the mixing pipe, resulting in obstruction of the flow of the two concrete raw materials, affecting the normal operation of the concrete batching device, and requiring manual shutdown for processing, which is inconvenient to operate; therefore, we proposed a batching device with an anti-blocking structure to solve the above problems.

At the same time, the conical spiral conveying blade and the first spiral conveying blade also have a certain mixing and stirring effect on the concrete raw materials.

[0009] Preferably, the two batching storage tanks on the top side of the batching box are symmetrically arranged, and the two batching storage tanks are connected to the batching cavity through corresponding batching ports, so as to facilitate batching of concrete raw materials in the batching storage tanks.

[0010] Preferably, the unloading and opening mechanism includes a second gear and a fan-shaped opening, and two second gears are installed on the inner wall of the top side of the batching chamber through a rotating shaft, and the two second gears are engaged with the first gear. The two second gears are each provided with a fan-shaped opening, and the fan-shaped opening is connected to the batching storage tank through the batching port; when the fan-shaped openings on the two second gears rotate to the corresponding batching ports, the concrete raw materials in the two batching storage tanks are poured into the batching chamber through the batching port and the fan-shaped opening.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Refer to Figure 1-4, a batching device with an anti-blocking structure includes a batching box 1, in which a batching chamber 2, a guiding chamber 3 and a conveying chamber 4 are sequentially opened. A first motor 5 is fixedly mounted on the top side of the batching box 1, and one end of a first driving rod 6 is fixedly mounted on the output shaft of the first motor 5. The other end of the first driving rod 6 extends into the batching chamber 2 and the guiding chamber 3 and is provided with an anti-blocking mechanism. Two batching ports 9 are respectively opened on the top side of the batching box 1, and two batching storage tanks 10 are respectively fixedly mounted on the top side of the batching box 1. A first gear 11 is fixedly mounted on the first driving rod 6, and a unloading opening mechanism for the first gear 11 is provided on the top inner wall of the batching chamber 2. A feeding mechanism for the conveying chamber 4 is provided on one side of the batching box 1.

[0022] Furthermore, the anti-blocking mechanism includes a conical spiral conveying blade 7 and a first spiral conveying blade 8. The conical spiral conveying blade 7 and the first spiral conveying blade 8 are respectively fixedly mounted on the first driving rod 6. The outer contact surface of the conical spiral conveying blade 7 rotates and fits against the inner wall of the batching chamber 2, and the outer contact surface of the first spiral conveying blade 8 rotates and fits against the inner wall of the guide chamber 3. The concrete raw materials falling into the batching chamber 2 are conveyed downward by the rotating conical spiral conveying blade 7 and the first spiral conveying blade 8, thereby avoiding the concrete raw materials from being blocked in the batching chamber 2 and the guide chamber 3, thereby ensuring the normal downward flow of the concrete raw materials. At the same time, the conical spiral conveying blade 7 and the first spiral conveying blade 8 also have a certain mixing and stirring effect on the concrete raw materials.

[0023] Specifically, the two batching storage tanks 10 on the top side of the batching box 1 are symmetrically arranged, and the two batching storage tanks 10 are connected to the batching cavity 2 through corresponding batching ports 9, so as to facilitate batching of concrete raw materials in the batching storage tanks 10.

[0024] Specifically, the unloading opening mechanism includes a second gear 12 and a fan-shaped opening 13. Two second gears 12 are installed on the inner wall of the top side of the batching chamber 2 through a rotating shaft. The two second gears 12 are engaged with the first gear 11. The two second gears 12 are each provided with a fan-shaped opening 13, and the fan-shaped opening 13 is connected to the batching storage tank 10 through the batching port 9; when the fan-shaped openings 13 on the two second gears 12 rotate to the corresponding batching port 9, the concrete raw materials in the two batching storage tanks 10 are poured into the batching chamber 2 through the batching port 9 and the fan-shaped opening 13.

[0025] Furthermore, the feeding mechanism includes a second motor 14, a second driving rod 15 and a second spiral conveying blade 16. The second motor 14 is fixedly installed on one side of the batching box 1, and the output shaft of the second motor 14 is fixedly installed with the second driving rod 15. The second spiral conveying blade 16 is fixedly installed on the second driving rod 15. The external contact surface of the second spiral conveying blade 16 rotates and fits on the inner wall of the conveying cavity 4; by starting the second motor 14, the second driving rod 15 drives the second spiral conveying blade 16 to rotate, thereby realizing the transportation of the batched concrete raw materials to the outside of the batching box 1.

[0026] Specifically, side grooves 17 are formed on both inner walls of the mixing chamber 2 , and part of the second gear 12 is located in the side grooves 17 ; the side grooves 17 can prevent the second gear 12 from fitting against the inner walls of the side grooves 17 during rotation.

[0027] During use: During the batching process of concrete raw materials, by driving the first motor 5, the first gear 11, the conical spiral conveying blade 7 and the first spiral conveying blade 8 on the first driving rod 6 are driven to rotate. Since the first gear 11 is engaged with the two second gears 12, the two second gears 12 are synchronously driven to rotate. When the fan-shaped openings 13 on the two second gears 12 rotate to the corresponding batching ports 9, the concrete raw materials in the two batching storage tanks 10 are poured into the batching chamber 2 through the batching ports 9 and the fan-shaped openings 13. The rotating conical spiral conveying blades 7 and the first spiral conveying blades 8 are used to downwardly convey the concrete raw materials falling into the batching chamber 2, thereby avoiding the concrete raw materials from being blocked in the batching chamber 2 and the material guide chamber 3, thereby ensuring the normal downward flow of the concrete raw materials. At the same time, the conical spiral conveying blades 7 and the first spiral conveying blades 8 also have a certain mixing effect on the concrete raw materials. At the same time, by starting the second motor 14, the second driving rod 15 drives the second spiral conveying blade 16 to rotate, thereby conveying the batched concrete raw materials to the outside of the batching box 1.
