Description

Technical Field

[0001] The utility model relates to the technical field of material feeding, in particular to a concrete quick-setting agent feeding device. Background Art

[0002] Concrete accelerator is a chemical additive specially designed to accelerate the setting and hardening of concrete. The main components of concrete accelerator usually include inorganic salts and organic substances, which exist in the form of powdered solids. The amount of concrete added in concrete is only 2% to 3% of the amount of cement, but it can significantly change the setting time of concrete, making it initially set within a few minutes and finally set within more than ten minutes. This rapid setting property makes the accelerator very suitable for special construction occasions such as emergency repair projects, mine shafts, railway tunnels, water diversion culverts and underground projects.

[0003] At present, in order to prevent the concrete accelerator from absorbing moisture in the air after being placed for a long time, a storage device is generally used to store it. Each time the concrete accelerator is used, a feeding device needs to be used to complete the operation of taking the concrete accelerator.

[0004] The prior art publication number is CN215592056U, which is a feeding device for producing concrete accelerating setting agent, comprising a feeding box, a sealing cover is arranged at the top of the feeding box, a feeding port is arranged at the bottom of the feeding box, a feeding shaft matching the feeding port is arranged at the feeding port, a cavity is arranged inside the feeding shaft, connecting shafts are arranged at the left and right ends of the feeding shaft, a support block is arranged in the middle of each connecting shaft, and several support rods are arranged at the bottom of the feeding box.

[0005] The device can quickly discharge the concrete accelerator quantitatively by cooperating with the discharge shaft and the cavity, replacing the manual weighing process and improving the construction efficiency. However, in actual use, due to the setting of the cavity size, only the set amount or an integer multiple of the set amount of concrete accelerator can be taken out when taking materials, and the material cannot be taken according to actual needs. If too much material is taken, it needs to be re-weighed, and then the excess concrete accelerator needs to be poured back into the discharge box, which is very troublesome. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a concrete accelerator feeding device, comprising a material box, a feeding pipe is fixedly passed through the bottom of the material box, a cylinder is fixedly passed through the bottom of the feeding pipe, a feeding shaft is rotatably connected to the inner wall of one side of the cylinder, and a power component is jointly installed between the feeding shaft and the cylinder; a plurality of feeding troughs are evenly provided on the outer surface of the feeding shaft, and the feeding troughs are connected to the inside of the feeding shaft, and the interiors of the plurality of feeding troughs are all sealed and slidably provided with adjustment plates; one end of the feeding shaft is fixedly connected to a driving motor, a driving end of the driving motor is fixedly connected to a bidirectional screw, and the bidirectional screw passes through the feeding shaft and is rotatably connected thereto, two sliding blocks are symmetrically threadedly sleeved on the outer surface of the bidirectional screw, a plurality of mounting grooves are provided on the outer surfaces of the two sliding blocks, and a connecting rod assembly is jointly installed between the plurality of mounting grooves and adjacent adjustment plates.

[0008] Furthermore, the power assembly includes a power motor, and the power motor is fixedly mounted on an outer wall of one side of the cylinder. The driving end of the power motor is fixedly connected to a rotating shaft, and the rotating shaft passes through the cylinder and is rotatably connected thereto. The rotating shaft is fixedly connected to the unloading shaft, and the cylinder has a supporting effect on the rotating shaft, which is beneficial to the installation of the rotating shaft.

[0009] Furthermore, the plurality of connecting rod assemblies all include a connecting rod body, and the connecting rod body is rotatably connected to the inner walls on both sides of the adjacent mounting grooves, the outer walls on both sides of the connecting rod body are rotatably connected together with a connecting block, and the connecting block is fixedly connected to the adjacent adjustment plate, and the setting of the connecting block is conducive to the rotatable connection between the connecting rod body and the adjustment plate.

[0010] Furthermore, two limit rods are fixedly connected to the inner walls on both sides of the unloading shaft, and the limit rods penetrate the slider and are slidably connected thereto. The limit rods have a limiting effect on the slider, thereby ensuring the stability of the movement of the slider.

[0011] Furthermore, a through hole is formed at one end of the cylinder, and the through hole matches the driving motor. The provision of the through hole is conducive to the installation of the driving motor and prevents the cylinder from affecting the use of the driving motor.

[0012] Furthermore, the outer wall of the discharge shaft is sealed and fitted with the inner wall of the cylinder, ensuring that the concrete accelerating setting agent can only be discharged through the discharge chute.
