Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and more specifically, to a spiral mixing device for slowing down the falling speed of materials. Background Technology

[0002] In the construction process of dry processing machinery, the conveyor height of the belt conveyor significantly affects the material conveying efficiency. Especially when conveying manufactured sand, a large drop in height when the conveyor belt is raised to a high position can cause segregation of the manufactured sand during its descent. This segregation not only leads to uneven particle distribution but can also affect the workability and malleability of the concrete, thus impacting project quality. Simultaneously, the dust settling velocity during the material's descent is relatively slow, making it prone to becoming suspended in the air and causing environmental pollution. Utility Model Content

[0003] The purpose of this invention is to provide a spiral mixing device that slows down the falling speed, thus solving the problem of material segregation during the unloading process of the conveyor.

[0004] This utility model is achieved through the following technical solution: a spiral mixing material device for slowing down the falling speed, including a conveyor, a drop-blocking cylinder is mounted on the unloading end of the conveyor, and a vertically arranged auger shaft is rotatably connected inside the drop-blocking cylinder. The material falls from the top of the drop-blocking cylinder, impacts the spiral blades of the auger shaft, causing the auger shaft to rotate, and transmits the material to the bottom of the drop-blocking cylinder to fall.

[0005] Furthermore, the spiral blade edge of the auger shaft is provided with protrusions.

[0006] Furthermore, a motor for driving the auger shaft to rotate is fixed at the top of the dropper cylinder.

[0007] Preferably, the top of the anti-fall cylinder is provided with a protective cover for installing the motor and preventing material leakage.

[0008] Furthermore, the upper part of the dropper cylinder is shaped like a bucket, wider at the top and narrower at the bottom.

[0009] This utility model has at least the following advantages and beneficial effects: by setting up a drop block at the discharge end of the conveyor, the material falls from the top of the drop block and impacts the auger shaft connected inside the drop block to generate rotation, and the material is transported to fall from the bottom of the drop block. This effectively controls the flow path of the material, slows down the falling speed of the material, reduces the possibility of segregation, further mixes the materials, and improves the uniformity and stability of the material.

[0016] The specific implementation method is described below with reference to the accompanying drawings.

[0017] Example 1

[0018] like Figure 1-4 As shown, this embodiment mainly discloses a spiral mixing device for slowing down the falling speed, including a conveyor 1. A drop-blocking cylinder 2 is mounted on the discharge end of the conveyor 1. A vertically arranged auger shaft 3 is rotatably connected inside the drop-blocking cylinder 2. Material falls from the top of the drop-blocking cylinder 2, impacting the spiral blades of the auger shaft 3, causing the auger shaft 3 to rotate and transporting the material to the bottom of the drop-blocking cylinder 2. Specifically, the auger shaft is made of a lightweight material, such as plastic or aluminum alloy, which can be easily rotated by the impact of falling material. The auger shaft is rotatably connected via a bearing 7 connected to the drop-blocking cylinder. Material is transferred to a higher position by conveyor 1. A dropper cylinder 2, supported by a bracket 6, is mounted on the discharge end of conveyor 1 to receive the material. Material falls from the discharge end of conveyor 1 into the dropper cylinder 2. Under the influence of gravity, the material impacts the spiral blades of the auger shaft 3, generating an impact force that causes the auger shaft 3 to rotate. This rotation gradually transfers the material to the bottom of the dropper cylinder 2, where it falls to form a pile. This effectively controls the material flow path, slows the falling speed, reduces the possibility of segregation, and further mixes the materials, improving their uniformity and stability.

[0019] Furthermore, in a specific implementation, the spiral blade edge of the auger shaft 3 provided in this embodiment of the present invention is provided with a protrusion 30. It should be noted that the protrusion 30 allows the material to converge towards the axis of the auger shaft 3 during the falling process, preventing the material from being thrown between the auger shaft 3 and the inner wall of the auger cylinder 2 due to the centrifugal force of rotation, thus hindering the smooth rotation of the auger shaft 3, reducing the probability of material getting stuck, and thereby enhancing the stability and flow efficiency of the entire device.

[0020] Furthermore, in specific implementations, the upper part of the aforementioned retaining cylinder 2 provided in this embodiment of the invention is shaped like a bucket, wider at the top and narrower at the bottom. This effectively guides the material downwards, reduces material retention, and ensures that the material flows smoothly into the retaining cylinder 2.

[0021] Example 2

[0022] like Figure 5 As shown, in this embodiment, the main structure is completely the same as in Embodiment 1, the difference being that a motor 4 for driving the auger shaft 3 to rotate is fixed at the top of the dropper cylinder 2. Preferably, a protective cover 5 for mounting the motor 4 and preventing material leakage is provided at the top of the dropper cylinder 2. Specifically, the output shaft of the motor 4 is coaxially connected to the auger shaft 3 via a coupling. The motor 4 mainly serves as an auxiliary drive. When material dropping is stuck or at the end of the material conveying process, and there is not enough material falling to provide a power source to make the auger shaft 3 rotate, the motor 4 is started to drive the auger shaft 3 to rotate, so that the material can fall smoothly and fully through the dropper cylinder 2.
