DETAILED DESCRIPTION

[0019] Referring to Figures 1-5As shown, the technical scheme adopted in the embodiment includes an upper cone bucket 1, a support rib plate 2 arranged on the top outer side of the upper cone bucket 1, a first connecting ring plate 3 arranged on the top of the support rib plate 2, a second connecting ring plate 4 arranged on the bottom of the support rib plate 2, the first connecting ring plate 3 and the second connecting ring plate 4 are welded with the upper cone bucket 1, and a third connecting ring plate 6 is arranged on the middle lower part of the upper cone bucket 1 and connected with a kiln shell 12 of a pallet discharge machine on the outer side. In the embodiment, the welding surface is increased by arranging three connecting ring plates, so as to improve the impact resistance of the upper cone bucket during discharging. In the traditional structure, the upper part of the upper cone bucket is connected with the kiln shell support only by welding with a single-layer support, which is equivalent to a suspended arm structure. Due to high temperature during production and the weight of the equipment itself, the upper cone bucket is easily broken and dust leakage occurs due to vertical impact during discharging. Therefore, in the embodiment, three connecting ring plates are arranged, and the thickness of the connecting ring plates is increased, so as to increase the welding area and improve the welding firmness, thereby improving the impact resistance. The arrangement of the support rib plate further improves the pressure bearing capacity of the first connecting ring and the impact resistance of the upper cone bucket, and reduces the risk of breakage at the welding position.

[0020] More specifically, the first connecting ring plate 3 extends into the inner side of the upper cone bucket 1. By extending the first connecting ring plate into the upper cone bucket 1 for a small distance, a certain dust prevention effect can be achieved during discharging, and the impact damage of the ore to the top edge of the upper cone bucket can also be prevented.

[0021] More specifically, the second connecting ring plate 4 is provided with a base 5 at the bottom, and the base 5 is installed on the kiln shell support. In the embodiment, the kiln shell body is provided with a kiln shell support, the base is arranged on the kiln shell support, and the second connecting ring plate is arranged on the base, thereby increasing the pressure bearing capacity of the ring plate and facilitating the maintenance of the equipment.

[0022] More specifically, the inner side of the middle lower part of the upper cone bucket 1 is provided with a bottom reinforcing ring plate 9, and a plurality of pallet discharge machine cross beam support frames 7 are arranged on the bottom reinforcing ring plate 9 and welded to the inner wall of the upper cone bucket 1. The bottom reinforcing ring plate is arranged in the middle lower part of the upper cone bucket, which plays the role of a reinforcing rib.

[0023] More specifically, the middle reinforcing rib plate 10 is arranged on the outer side of the middle part of the upper cone bucket 1, and the middle reinforcing rib plate 10 is provided with a middle reinforcing ring plate 11 at the bottom. In order to further improve the overall strength of the upper cone bucket, the middle reinforcing rib plate is arranged in the middle part of the upper cone bucket, and the middle reinforcing ring plate is arranged at the bottom of the middle reinforcing rib plate. The middle reinforcing ring plate can support the middle reinforcing rib plate, thereby improving the supporting effect of the middle reinforcing rib plate on the upper cone bucket.

[0024] More specifically, the support rib plate 2 is provided with a first welding groove 2-1 and a second welding groove 2-2 at the connection with the upper cone 1. In this embodiment, two welding grooves are provided on the support rib plate, which can effectively increase the welding area, thereby improving the welding firmness, and further improving the overall impact resistance of the equipment.

[0025] More specifically, the inner reinforcing plate 8 is provided at the top inner side of the upper cone 1, and the inner reinforcing plate 8 is provided corresponding to the support rib plate 2. The provision of the inner reinforcing plate not only increases the structural strength of the equipment, but also avoids the direct impact of the mineral material on the upper cone during the discharging process, thereby prolonging the service life of the equipment and the maintenance cycle, and improving the production efficiency.

[0026] The working principle of the utility model is as follows: the base 5 is welded on the kiln shell support, and the support rib plate 2, the first connecting ring plate 3 and the second connecting ring plate 4 are arranged on the base 5, all of which are welded with the upper part of the upper cone 1, and two welding grooves are arranged on the support rib plate 2 to strengthen the welding with the upper cone 1, thereby improving the welding firmness, so that the two connecting ring plates can effectively improve the impact resistance of the upper cone 1 during discharging, and the welding of the two welding grooves further improves the impact resistance, thereby effectively preventing cracking. The middle and lower parts of the upper cone 1 are provided with the third connecting ring plate 6 connected with the kiln shell 12 of the tray discharging machine, and the kiln shell 12 of the tray discharging machine is also provided with a channel steel in the horizontal direction to support the third connecting ring plate 6, thereby improving the impact resistance of the lower part of the upper cone 1 and further preventing the welding seam of the third connecting ring plate 6 and the upper cone 1 from cracking. When maintenance is needed, the workers can conveniently maintain the welding parts of the support rib plate 2, the first connecting ring plate 3 and the second connecting ring plate 4 above the upper cone 1, and the welding parts of the third connecting ring plate 6 on the tray discharging machine disc can be maintained from the bottom of the upper cone 1. The design of the multiple thickened connecting ring plates can effectively improve the impact resistance of the upper cone 1 during discharging, and the welding area is increased to increase the welding firmness.
