[0002] Concrete is a general term for engineering composite materials that are made by bonding aggregates into a whole with cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, mixed with water in a certain proportion and obtained by mixing. It is also called ordinary concrete and is widely used in civil engineering.

[0003] The existing technology mostly adopts a concrete charging port plugging device disclosed in the announcement number CN217967676U. This technology includes a house body, a mounting frame is provided on the outside of the discharge pipe, and the mounting frame is a rectangular frame structure. The top of the mounting frame is fixedly connected to the house body, and the lower end of the discharge pipe is abutted with a plugging plate, and the plugging plate is placed inside the mounting frame. This technology has a plugging plate slidably connected to the lower end of the discharge pipe. The plugging plate is driven to move by a driving device, and the discharge pipe is blocked after loading to prevent residual concrete from falling to the bottom surface of the loading station. However, the above technology still has problems during use due to structural limitations:

[0004] In the above technology, after loading is completed, the discharge pipe is blocked by a blocking plate, so that the residual concrete remains in the discharge pipe. At the same time, due to the lack of movable concrete parts in the discharge pipe, the concrete remains stationary for a long time and solidifies, so that the discharge pipe is blocked by concrete and can no longer transport concrete. Utility Model Content

[0005] The utility model aims to solve the problem that residual concrete in the prior art easily blocks a discharge pipe, and proposes a concrete charging port blocking device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0025] 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.

[0026] Reference Figure 1-Figure 3 A concrete charging port plugging device comprises a housing body 1, a concrete discharge pipe seat 2 and a concrete discharge pipe head 3 are arranged on the housing body 1, the upper end of the concrete discharge pipe seat 2 is fixedly connected to the lower end of the housing body 1, and the concrete discharge pipe head 3 is slidably sleeved in the concrete discharge pipe seat 2. When there is concrete in the concrete discharge pipe seat 2, the concrete directly falls into the concrete discharge pipe head 3, so as to discharge the concrete;

[0027] The room body 1 is also provided with an electric telescopic rod 8, a fixing ring 9 and an auger blade 7. The two electric telescopic rods 8 are fixedly installed on the outer wall of the concrete discharge pipe seat 2. The fixing ring 9 is integrally formed on the outer wall of the concrete discharge pipe head 3, and the fixing ring 9 is fixedly connected to the output ends of the two electric telescopic rods 8. The concrete discharge pipe head 3 adjusts the height of the concrete discharge pipe head 3 through the telescopic movement of the two electric telescopic rods 8, so as to load the loading vehicles of different heights. The auger blade 7 is movably arranged at the center of the concrete discharge pipe head 3, and the auger blade 7 is fitted with the inner wall of the concrete discharge pipe head 3. When the auger blade 7 spirally rotates downward, the concrete in the concrete discharge pipe head 3 is discharged, and when the auger blade 7 spirally rotates upward, the concrete in the concrete discharge pipe head 3 is pushed upward to prevent the concrete from continuing to flow downward, and the concrete is moved to avoid the concrete from solidifying.

[0028] The driving mechanism is arranged on the concrete discharge pipe head 3, and is used to drive the auger blades 7 to rotate upward or downward in a spiral, thereby pushing the concrete upward or discharging it downward.

[0029] The first fixing rod 4 and the second fixing rod 10 are respectively fixedly connected in the concrete discharge pipe head 3, and the first fixing rod 4 and the second fixing rod 10 are respectively fixedly connected to the first bearing seat 5 and the second bearing seat 11. The outer wall of the concrete discharge pipe head 3 is fixedly connected with a clamping hoop 12, and the clamping hoop 12 is located below the fixing ring 9.

[0030] The driving mechanism includes a rotating rod 6, a connecting rod 14 and a servo motor 13. The rotating rod 6 is arranged in the concrete discharge pipe head 3. The upper and lower ends of the rotating rod 6 are respectively rotatably sleeved in the second bearing seat 11 and the first bearing seat 5. At the same time, the first bearing seat 5 and the second bearing seat 11 are used to make the rotating rod 6 rotate stably, and the connecting rod 14 is rotatably installed in the concrete discharge pipe head 3. The servo motor 13 is fixedly installed on the clamping hoop 12, and the output end of the servo motor 13 extends to the concrete discharge pipe head 3 and is fixedly connected to the connecting rod 14.

[0031] The first bevel gear 15 and the second bevel gear 16 are key-connected to the connecting rod 14 and the rotating rod 6 respectively. Since the first bevel gear 15 and the second bevel gear 16 are meshingly connected, and the rotating rod 6 is fixedly connected to the auger blade 7, when the output end of the servo motor 13 drives the connecting rod 14 to rotate, the auger blade 7 is rotated.

[0032] The functional principle of the utility model can be explained through the following operation modes:

[0033] The electric telescopic rod 8 drives the fixing ring 9 to move up and down, and the fixing ring 9 drives the concrete discharge pipe head 3 to move up and down, so as to adjust the height of the concrete discharge pipe head 3, and then load the loading vehicles at different heights;

[0034] When the concrete discharge pipe head 3 is discharging, the servo motor 13 is started, and the output end of the servo motor 13 drives the connecting rod 14 to rotate, and the connecting rod 14 drives the first bevel gear 15 to rotate. Since the first bevel gear 15 is meshed and rotated with the second bevel gear 16, the second bevel gear 16 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the auger blade 7 to rotate, and then the concrete in the concrete discharge pipe head 3 is discharged downward through the auger blade 7. When the concrete is stopped from being discharged, the servo motor 13 is started to rotate in the opposite direction, so that the auger blade 7 makes an upward spiral rotation, thereby preventing the residual concrete in the concrete discharge pipe head 3 from flowing downward, and also preventing the residual concrete from solidifying in the concrete discharge pipe head 3 and causing blockage.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
