[0008] The conveying assembly includes two belt conveyors, respectively arranged below the first and second receiving hoppers. With this arrangement, the position of the covering can be adjusted to flexibly select either the first or second receiving hopper for unloading.

Therefore, they should not be construed as limitations on this utility model.
[0025] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.
[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be further discussed and described in the description of the subsequent figures.
[0027] Example:
[0028] like Figures 1 to 2 As shown, this utility model provides a metallurgical sintering raw material unloading shielding system, including: a receiving hopper group, a shielding component, and a conveying component; the receiving hopper group includes components along a first direction ( Figure 1 A first receiving hopper 1 and a second receiving hopper 2 are arranged side by side (in the direction shown by X in the middle); the shielding assembly includes a track 3 and a shielding cover 4; the track 3 extends along a first direction, and two tracks 3 are arranged opposite each other on both sides of the first receiving hopper 1 and the second receiving hopper 2; the shielding cover 4 is slidably disposed on the track 3 so that the shielding cover 4 has a first station, a second station, and a third station; wherein, when the shielding cover 4 is located at the first station or the second station, it is the unloading mode of this system, and when the shielding cover 4 is located at the third station, it is the rainproof mode of this system. Specifically, when the shielding cover 4 is in the first station (refer to...), Figure 1 When the cover 4 is in the second position, it covers the first receiving hopper 1, while the second receiving hopper 1 is open, allowing the transport vehicle 12 to unload material through the second receiving hopper 2. When the cover 4 is in the third position, it covers both the first and second receiving hoppers 1 and 2 simultaneously, in a rainproof mode to prevent water accumulation in the first and second receiving hoppers or rainwater from wetting the belt conveyors 5 below them. The conveying assembly includes two belt conveyors 5, respectively arranged below the first and second receiving hoppers 1 and 2, for conveying materials falling from the first and second receiving hoppers 1 and 2 to the next process. The belt conveyors are also equipped with a blockage sensor (existing devices can meet this requirement).
[0029] In practice, both ends of track 3 extend away from the first receiving hopper 1 and the second receiving hopper 2, so that the length of track 3 is greater than the sum of the opening lengths of the first receiving hopper 1 and the second receiving hopper 2, thereby ensuring that the shielding cover 4 has sufficient space to move to the first and second workstations. The capacity of the two receiving hoppers is 10-20m³. 3 The inner lining is made of wear-resistant steel plate (10-16mm thick).
[0030] The metallurgical sintering raw material unloading shielding system of this utility model can flexibly select either the first receiving hopper 1 or the second receiving hopper 2 for unloading by moving the position of the shielding cover 4. In case of rain, it can simultaneously shield the first receiving hopper 1 and the second receiving hopper 2 to prevent water from entering the hoppers. It does not affect the unloading operation and can also shield both hoppers at the same time in case of rain.
[0031] Specifically, the shelter cover 4 includes a first slope 401 and a second slope 402; the highest section of the first slope 401 is connected to the highest section of the second slope 402, and the lowest section of the first slope 401 is far from the lowest section of the second slope 402. The triangular truss formed by the first slope 401 and the second slope 402 gives the shelter cover 4 a slope, preventing water accumulation. Furthermore, the first slope 401 and the second slope 402 are made of corrugated corrugated steel sheets, which facilitates rainwater drainage.
[0032] This embodiment also includes a track wheel 6; the shielding cover 4 cooperates with the track 3 via the track wheel 6, allowing the shielding cover 4 to be slidably mounted on the track 3. By using the track wheel 6, the pushing resistance of the shielding cover 4 can be ≤200N. Under this pushing resistance, the shielding cover 4 can be moved manually. This embodiment eliminates the need for energy-intensive and high-failure-rate electric or hydraulic drive devices. Manually pushing the shielding cover 4 results in low investment costs, ease of maintenance, and facilitates large-scale promotion.
[0033] Specifically, in this embodiment, the cover is a two-way non-powered rainproof cover, with handles (not shown in the figure) on both sides of the cover 4 for easy gripping and manual two-way pushing of the cover 4.
[0034] Stiffening plates 13 for fixing the rails 3 are provided on the outer sides of both sides of the first receiving hopper 1 and the outer sides of both sides of the second receiving hopper along the first direction. Specifically, the rails on both sides are made of round steel / steel pipe with a diameter of 30-50mm. Triangular stiffening plates (one set welded every 0.5-1m, side length 200-250mm, thickness 10-16mm) are fixed to the side walls of the two receiving hoppers along the first direction. The rails are fixed and the levelness is calibrated (error <3mm) by the triangular stiffening plates.
[0035] In this embodiment, a limiting device is also included, comprising a first limiting member 7 and a second limiting member 8. The first limiting member 7 is disposed at the first end of the track 3, and the second limiting member 8 is disposed at the second end of the track 3. When in the first working position, the shielding cover 4 contacts the first limiting member 7; when in the second working position, the shielding cover 4 contacts the second limiting member 8. Both the first limiting member 7 and the second limiting member 8 are mechanical limiting blocks. The mechanical limiting block has a groove with an arc surface on the side facing the track wheel 6 for cooperating with the track wheel 6. When the shielding cover moves towards the first or second working position, the track wheel 6 contacts the groove of the limiting block and is thus stopped and unable to move further. At this time, the shielding cover 4 is in the first or second working position.
[0036] This embodiment also includes a dust suppression and drainage device, specifically a dust curtain and an atomizing spray assembly. The dust curtain 9 is installed along the first direction on both sides of the shielding cover 4, which can shield the dust that flies up during unloading. The atomizing spray assembly includes spray pipes 10 and atomizing nozzles 11; spray pipes 10 are arranged on the side walls of the open ends of the first receiving hopper 2 and the second receiving hopper 2, and the atomizing nozzles 11 are evenly distributed on the spray pipes 10. By setting up the atomizing spray assembly, a large amount of dust can be avoided from flying up during unloading.
[0037] In practical use:
[0038] refer to Figure 1 The outer sides of the first receiving hopper 1 and the second receiving hopper 2 are unloading platforms to facilitate the passage of the transport vehicle 12. During unloading, the roof is manually pushed to the target position (the first or second workstation), and the corresponding belt conveyor is started; the transport vehicle enters the opened unloading position; the atomizing spray is turned on simultaneously during unloading. During non-operational periods, the cover is pushed to the center, the atomizing spray is turned off, and the system enters rain protection mode.
[0039] This invention provides a highly efficient, energy-saving, and environmentally friendly metallurgical sintering raw material unloading and shielding system. It integrates a bidirectional, non-powered shielding cover, allowing manual switching between unloading and rain protection modes. In unloading mode, the unloading station can be selected based on actual conditions. This system enables rapid unloading from transport vehicles, all-weather rain and dust protection, and low-maintenance operation, facilitating large-scale deployment.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
