Description

Technical Field

[0001] This utility model relates to the field of cement mixing pile processing technology, specifically a cement dosage control device for cement mixing piles. Background Technology

[0002] Cement mixing piles are a common method for treating soft soil foundations. They involve forcibly mixing cement and other solidifying agents with the soft soil, causing it to harden and thus increasing the bearing capacity of the foundation and reducing settlement. They are widely used in road, bridge, and building construction projects. In these projects, the quality of the cement mixing piles directly affects the stability and safety of the entire project, and the cement dosage is a key factor influencing the quality of the cement mixing piles.

[0003] In the early stages of cement mixing pile construction, cement dosage was mostly controlled manually. Workers added cement based on experience, making it difficult to accurately control the amount of cement used in each pile. This resulted in uneven cement dosage, large dispersion in pile quality, and the cement being in powder form with gaps, which easily led to deviations in measurement. Utility Model Content

[0004] The purpose of this invention is to provide a cement dosage control device for cement mixing piles, which has the advantage of accurately controlling the cement dosage and solves the problem of difficulty in controlling the cement dosage in current cement mixing piles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cement dosage control device for cement mixing piles, comprising a storage mechanism, a closing mechanism at the top of the storage mechanism, a rotary motor at the bottom, a control mechanism connected to the output end of the rotary motor, a guide pipe connecting the closing mechanism and the control mechanism at an inclined position at the bottom of the closing mechanism, a storage cylinder, a bottom plate at the bottom of the storage cylinder, a through hole on the bottom plate, a rotating plate rotatably mounted on the through hole, the rotating plate being connected to the rotary motor via a bevel gear, and a sealing plate at the top of the sealing mechanism, the sealing plate being placed at the top of the storage cylinder, and a cover plate being provided at the top of the sealing plate.

[0006] Preferably, the rotating plate is a trapezoidal plate structure, and the two sides of the rotating plate are attached to the inner wall of the storage cylinder. The rotating plate is symmetrical about its axis and divided into two parts. One part has several round holes inside, and the other part has several through slots equidistantly opened on the outside. A frame is provided at the top of the rotating plate.

[0007] Preferably, the frame is U-shaped, with its opening facing the rotating plate, and a round shaft is provided at the top of the frame.

[0008] Preferably, the control mechanism includes a circular tube, one end of which is connected to a guide tube, and the other end of which is fitted with a metering tube. The metering tube is a cylindrical structure with one end closed, and two symmetrically rotatable flaps are arranged at the bottom end of the metering tube. Four limiting frames are arranged in a ring array at equal intervals around the axis of the circular tube. The inner edges of the four limiting frames are all in contact with the outer edges of the metering tube, and the outer edges of the four limiting frames are all provided with scales.

[0009] Preferably, a rotating shaft is provided inside the circular tube, and a rotating blade is provided on the outer edge of the rotating shaft. The rotating shaft is connected to the output end of a rotary motor, and the outer edge of the rotating blade is in contact with the inner edge of the circular tube.

[0010] Preferably, the outer edge of the metering tube is provided with four limiting plates embedded in the limiting frame in a ring array around its axis, and each of the four limiting plates is rotatably mounted with a handle at its top.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a circular tube, a metering tube, a limiting frame, a rotating shaft, a rotating blade, a flap, a limiting plate, a handle, and a scale, connects the circular tube to a guide tube, which in turn connects to the inside of a storage cylinder. The rotating shaft drives the rotating blade to rotate, transporting cement from the circular tube to the metering tube. The limiting plate slides within the limiting frame, changing the distance the metering tube extends beyond the end of the circular tube. The distance is controlled by the limiting plate pointing to the scale. Rotating the handle fixes the circular tube and the metering tube. As cement is continuously transported into the metering tube, it is compacted, ensuring accurate control of the cement dosage. Then, rotating the flap opens the cement, allowing for precise control of the cement dosage. This helps improve construction efficiency and quality, reduces labor intensity, avoids cement waste, lowers project costs, and reduces the environmental impact of excessive cement use, aligning with the concept of green construction.

[0013] 2. This utility model, by setting up a storage tube, a rotating plate, a frame, a round hole, and a through groove, allows the rotating plate to rotate inside the storage tube. The rotating plate and the frame adhere to the inner wall of the storage tube, which can scrape off the cement hanging on the inner wall of the storage tube, avoiding cement adhesion and the resulting waste of cement. The round hole and through groove on the rotating plate can reduce the resistance of the cement during rotation. Attached Figure Description
