Description

Technical Field

[0001] This utility model relates to the field of mineral sorting equipment, and in particular to an adjustable cloth feeding device applied to a mineral intelligent sorting machine. Background Technology

[0002] Existing intelligent mineral sorting machines generally use belt conveyors to directly feed ore materials into the identification area. However, due to the large differences in particle size and significant fluctuations in flow rate, the materials are often unevenly distributed on the conveyor belt, resulting in concentrated stacking or segregation, which in turn affects the imaging quality of X-ray identification and reduces the sorting accuracy.

[0003] For example, Chinese patent CN202606270U, ​​"A Self-flowing Ore Distributor," proposes a distributing device that expands the width of the material distribution through multi-stage guide plates. While this improves the problem of concentrated material accumulation, the structure is fixed and cannot be flexibly adjusted according to different working conditions. Another example is Chinese patent CN208751294U, "Cooling Device for Sintered Ore Vertical Shaft Furnace with Top Anti-segregation Distributing and Bottom Matching Air Distribution," which provides a top anti-segregation distributing structure and improves material distribution. However, it mainly addresses the sintered ore cooling process and fails to solve the problem of material uniformity on high-speed conveyor belts.

[0004] Therefore, existing fabric spreading devices lack adjustability, and are prone to uneven distribution and local segregation during the fabric spreading process. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a fabric feeding device with reasonable structure and strong adjustability.

[0006] In order to solve the above-mentioned technical problems, the present invention provides the following technical solution: an adjustable cloth feeding device for a mineral intelligent sorting machine, including a cloth feeding box 1 and a conveyor belt 5.

[0007] As a preferred technical solution of this utility model, the outlet of the material box 1 is provided with an adjustable guide plate 2. The adjustable guide plate 2 is driven by an electric push rod 21 and is used to adjust the outlet width or angle according to the material characteristics so that the ore flow can be dispersed laterally during the falling process.

[0008] As a preferred technical solution of this utility model, a vibrating material distributor 3 and an air curtain nozzle group 4 are arranged sequentially below the outlet of the material distribution box 1. The vibrating material distributor 3 includes a vibrating motor 31 and a support plate 32. The vibrating motor 31 is installed on the side of the support plate 32 and fixedly connected to it to drive the support plate 32 to vibrate for loosening the material.

[0009] As a preferred technical solution of this utility model, the air curtain nozzle group 4 includes multiple nozzle units arranged on the left and right sides of the conveyor belt 5, with the spray direction pointing horizontally towards the center of the conveyor belt, so as to form opposing transverse airflows and evenly spread the material on the conveyor belt 5.

[0010] As a preferred embodiment of this utility model, an adjustable support frame 6 is provided between the vibrating fabric distributor 3 and the conveyor belt 5 to adjust the relative height between the fabric distributor and the conveyor belt 5, which facilitates installation and maintenance.

[0011] As a preferred embodiment of this invention, the device may also be equipped with a control system 7, which is connected to a flow sensor, a particle size sensor, or a material layer thickness sensor. The control system can adaptively adjust the operating parameters of the electric push rod 21, the vibrating motor 31, and the nozzle unit based on the sensor signals. The control system may employ a programmable logic controller (PLC) or a microcontroller module, and has preset program and parameter storage functions to achieve automated material distribution optimization under different working conditions.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device achieves dual homogenization of materials in both the width and thickness directions through a multi-stage synergistic effect of "flow guidance and dispersion - vibration loosening - air curtain shaping," avoiding concentrated material accumulation and segregation. 2. All adjustment components of this device are driven by electric push rods or a control system, making adjustment convenient and adaptable to different particle sizes, flow rates, and other working conditions. 3. This device has a reasonable structural design and a high degree of automation, enabling it to stably obtain a uniform and continuous thin material layer under different working conditions, thereby improving the recognition imaging quality and sorting accuracy of the intelligent sorting machine.

[0019] Furthermore, the vibration motor 31 is mounted on the side of the support plate 32 and fixedly connected thereto, for driving the support plate 32 to vibrate.

[0020] Furthermore, the air curtain nozzle group 4 includes multiple nozzle units, which are evenly distributed along the transverse direction of the conveyor belt 5, with the spray direction pointing towards the center line of the conveyor belt 5, forming opposing transverse airflows.
