Description

Technical Field

[0001] This utility model relates to the field of concrete feeding technology, and in particular to a concrete mixing and feeding device. Background Technology

[0002] When mixing concrete, the traditional method is for workers to carry the concrete to the concrete mixing equipment at a designated location, then cut open the concrete bag with a blade and manually pour the concrete into the mixing equipment for mixing.

[0003] A search revealed a Chinese patent with publication number CN217802493U, which discloses a concrete mixing auxiliary feeding device. This device facilitates the feeding of concrete into the mixing tank for mixing and avoids the occurrence of smoke and dust during the mixing process, thus ensuring the health of the workers. However, since the device directly feeds the raw materials into the mixing device, there may be impurities in the raw materials. If these impurities are not removed, the quality of the concrete will be affected. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A concrete mixing and feeding device includes a base plate 1. Multiple support columns 2 are bolted to the upper surface of the base plate 1. A hopper 3 is bolted to the top of each support column 2. An inclined filter plate 8 is bolted inside the hopper 3. A clearance opening 9 is provided on one side of the hopper 3. The lower part of the filter plate 8 passes through the clearance opening 9. A feeding assembly for conveying materials into the hopper 3 is provided on the upper surface of the base plate 1. In use, concrete raw materials are added to the hopper 3. The hopper 3 then screens out impurities or larger stones from the raw materials, while the filter plate 8 filters out these impurities. This prevents impurities from affecting the quality of the concrete and improves the feeding device's effectiveness. Furthermore, because the filter plate 8 is inclined, the impurities screened out by the filter plate 8 roll on the inclined filter plate 8 and then roll out of the hopper 3 through the clearance opening 9, preventing impurities from remaining on the filter plate 8 and clogging it.

[0024] In this invention, the feeding assembly includes a straight pipe 4, which is disposed on the top of the base plate 1. A connecting pipe 11 is welded to one side of the straight pipe 4 at its bottom position, and the connecting pipe 11 is located at the lowest point of the hopper 3 and is connected to the hopper 3. A rotating shaft 12 is rotatably connected inside the straight pipe 4, and a spiral blade 13 is welded to the outside of the rotating shaft 12. An L-shaped feed pipe 7 is welded to one side of the straight pipe 4 at its top position. The top of the straight pipe 4 is provided with a power component for driving the rotating shaft 12 to rotate. The power component is a motor 5, which is fixed by bolts. Fixed at the top of the straight pipe 4, one end of the output shaft of the motor 5 passes through the straight pipe 4 and is fixed to the rotating shaft 12 by a coupling. Multiple support rods 14 are welded to the top of the base plate 1 and the support rods 14 are fixed to the straight pipe 4. The screened raw material will enter the straight pipe 4 through the connecting pipe 11. Then the motor 5 is started, the motor 5 drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the spiral blade 13 to rotate. During the rotation, the spiral blade 13 will transport the raw material upward in the straight pipe 4, thereby adding the raw material into the mixing tank through the L-shaped material pipe 7.

[0025] In particular, a U-shaped plate 6 is bolted to one side of the hopper 3 at the avoidance opening 9, and the spacing of the U-shaped plate 6 is equal to the length of the avoidance opening 9. The U-shaped plate 6 guides the impurities that roll out through the avoidance opening 9. A vibration pump 10 is bolted to the bottom outer wall of the hopper 3 at the center. During the screening of raw materials, the vibration pump 10 can be started. The vibration pump 10 will cause the hopper 3 to vibrate, and through the transmission between solids, it will cause the filter plate 8 to vibrate, thereby enabling the filter plate 8 to screen the raw materials better and improve the screening effect. At the same time, the vibration pump 10 can make the impurities on the filter plate 8 better discharged through the avoidance opening 9. Multiple self-locking universal wheels 15 are bolted to the bottom of the bottom plate 1, and the multiple self-locking universal wheels 15 are evenly distributed.

[0026] Working principle: During use, concrete raw materials are added to hopper 3. At this time, hopper 3 will screen out impurities or larger stones in the raw materials. The screened raw materials will enter straight pipe 4 through connecting pipe 11. Then, motor 5 is started, which drives shaft 12 to rotate. Shaft 12 drives spiral blade 13 to rotate. During the rotation of spiral blade 13, the raw materials are conveyed upward in straight pipe 4, and then added to the mixing tank through L-shaped material pipe 7. Filter plate 8 filters out impurities in the raw materials, thereby avoiding impurities in the raw materials from affecting the quality of concrete and improving the use effect of the feeding device. During the screening of raw materials, vibration pump 10 can be started. Vibration pump 10 will cause hopper 3 to vibrate, and through the transmission between solids, it will cause filter plate 8 to vibrate, thereby enabling filter plate 8 to screen raw materials better and improve the screening effect.

[0027] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
