At least two support columns are arranged on the upper part of each group of walking alignment devices 1 for supporting the silo installation platform.

[0033] In a preferred embodiment, the silo mounting platform is a steel frame structure, which has high strength and stability.

[0034] In conjunction with the embodiment of the utility model, two rows of silos 3 are installed on the silo installation platform. In a specific embodiment, refer to Figure 1 , the number of silos 3 in each row is 3.

[0035] In order to better support the silo installation platform, when there are three silos 3 in each row, four support columns are arranged on the upper part of each group of walking alignment devices 1 to support the silo installation platform. Preferably, the support columns are arranged at intervals from the silos 3.

[0036] In combination with the embodiment of the utility model, a bag unpacking device 5 is provided at the upper feed port of the silo 3, wherein the bag unpacking device 5 is an inverted cone bag breaker. The inverted cone bag breaker includes four triangular steel plates distributed in a cross shape, and a relatively sharp blade is provided on the outer edge of the triangular steel plate, and the bag unpacking is realized by using the relatively sharp blade.

It can not only improve the working environment, but also collect dust materials, reducing waste and consumption.

[0040] In combination with the embodiment of the utility model, the utility model provides a working process of an automatic dry material feeding device for a tundish working layer as follows:

[0041] (1) Place the tundish that needs to be knotted at the knotting construction station and install the inner tube membrane in the right position.

[0042] (2) Use the on-site crane to lift the dry material to the silo 3, and use the bag unpacking device 5 to realize the automatic filling function. The material anti-segregation device installed inside the silo 3 evenly places the dry material in the silo 3. During this period, the dust collector is started, and the dust generated during the automatic bag unpacking is collected and collected into the dust collector through the dust recovery port 4. This process uses a crane to cooperate with the automatic material distribution device to complete the material discharge, which can eliminate the safety risks of lifting in the manual material discharge process and reduce the labor intensity of employees; eliminate the problem of dust that is easy to generate during on-site material discharge, improve the job environment, and make the work site cleaner and tidier; dust is recovered in time to reduce dry material consumption and reduce the company's operating costs; solve the material segregation problem caused by the direct unloading of materials from the material tank or ton bag, and make the quality of the knotted middle bag working layer more stable.

[0043] (3) Start the walking alignment device 1 of the automatic material placing device, and move the automatic material placing device to the knotting construction position for precise alignment. This can eliminate the safety risk of material hoisting collapse during the knotting work layer operation of the workers; realize the automatic precise alignment function of the tundish, and improve the work efficiency.

[0044] (4) The staff is located on the platform above the walking alignment device 1, manually operates the discharge valve 2, and uses a hose to fill the dry material into the working layer of the tundish for knotting. This can achieve the effect of filling the working layer in small quantities and multiple times, reducing material waste caused by knotting the working layer; reducing the company's operating costs; making it easier for employees to operate the equipment, reducing the labor intensity of employees, and improving work efficiency.

[0045] (5) After the tundish is tied, the dust collector is closed, the dust material in the dust collector is recovered to the silo 3, the walking alignment device 1 is started, and the automatic material distribution device is returned to the parking area to wait for the next step. Since dust is also a material, the collected dust material can be reused, which reduces the consumption of dry materials and reduces the company's operating costs.

[0046] The automatic material placing device provided by the embodiment of the utility model can realize accurate material placing, eliminate material waste, solve the problem of environmental pollution on the work site, avoid the safety hazard of hanging objects falling and injuring people when tying the working layer, and at the same time optimize the post personnel, reduce labor intensity, improve work efficiency, and reduce material waste.
