Description

Technical Field

[0001] The utility model relates to the field of raw material transportation, in particular to a buffer transfer chute. Background Art

[0002] At present, the domestic metallurgical industry material conveying system includes belts and transfer stations. To ensure the overall transportation effect, designers often focus on solving the problems that occur in belt conveying, while ignoring the design of the internal transportation channels in the transfer stations (chutes).

[0003] In the prior art, during the actual transfer process, as Figure 1 shown, after various raw materials and finished ores fall into the transfer station (chute), the various raw materials and finished ores continuously impact and squeeze the lining plate of the chute inner wall and then fall. Moreover, the transportation channel in the transfer station (chute) is not provided with a buffer inclined plate structure, resulting in a large height difference in the fall of various raw materials and finished ores. This makes it extremely easy for various raw materials and finished ores to be broken during the falling process and when they fall onto the belt. The broken raw materials and finished ores do not meet the production regulations, so they need to be returned for reprocessing, increasing the overall transportation cost. At the same time, various raw materials and finished ores fall from a high place and damage the belt below, increasing the time for personnel maintenance and inspection. Summary of the Utility Model

[0033] To further understand the purpose, structure, features and functions of the present utility model, the following is a detailed description in conjunction with the embodiments.

[0034] As Figure 2-6 shown, a buffer transfer chute provided according to an embodiment of the present utility model includes:

[0035] A first receiving part 1000, a second receiving part 2000, a third receiving part 3000 and a blocking part,

[0036] The second material receiving opening 2300 of the second receiving part 2000 is connected to the first material discharging opening 1400 of the first receiving part 1000, the second material discharging opening 2400 of the second receiving part 2000 is connected to the third material receiving opening 3200 of the third receiving part 3000. At the same time, the first receiving part 1000 and the second receiving part 2000 are respectively provided with a first boss 1100 and a second boss 2100, and the blocking part 4000 is respectively arranged on the first boss 1100 and the second boss 2100, so that the blocking part 4000 forms a first storage tank with the inner wall of the first receiving part 1000 on the first boss 1100, and the blocking part 4000 forms a second storage tank with the inner wall of the second receiving part 2000 on the second boss 2100. Moreover, the first receiving part 1000 and the second receiving part 2000 are both provided with a first inclined surface 1200 and a second inclined surface 2200, and the third receiving part 3000 is provided with a third buffer surface 3100.

[0037] Among them, when various raw materials and finished ores are transferred to a buffer transfer chute of the present utility model, Figure 3 The solid arrows in the figure are the raw material dropping and transfer routes. Various raw materials and finished product frames enter the inner cavity of the first receiving part 1000 from the first material receiving port 1300. Various raw materials and finished ores will preferentially fall into the first storage tank until the raw materials are full. At this time, the raw materials full in the first storage tank form a primary buffer 8100. The primary buffer 8100 is in an inclined plane. The conveyed raw materials will directly fall on the primary buffer 8100, thereby buffering the raw materials and continuing to guide the raw materials to fall into the second receiving part 2000. The raw materials falling into the second receiving part 2000 will preferentially fall into the second storage tank until the raw materials are full. At this time, after the raw materials full in the second storage tank, a secondary buffer 8200 is formed. The secondary buffer 8200 is in an inclined plane. At this time, the raw materials falling from the first receiving part 1000 will fall on the secondary buffer, further buffering the raw materials and guiding the raw materials to fall into the third receiving part 3000. The raw materials falling into the third receiving part 3000 are buffered by the third buffer surface 3100 again. This third buffer surface 3100 is a tertiary buffer 8300. Finally, the raw materials are discharged from the third material discharging port 3300 of the third receiving part 3000 after passing through the tertiary buffer 8300. Among them, the raw materials are buffered by multiple levels, reducing the breakage rate and reducing rework.

[0038] Furthermore, as Figure 2 , Figure 3 and Figure 4 shown, the buffer transfer chute further includes an input component 5000. The input component 5000 is arranged on the first receiving part 1000. The input component 5000 includes a dust-proof cover 5100 and a belt output end 5200. The dust-proof cover 5100 covers the first material receiving port 1300 of the first receiving part 1000. The belt output end 5200 is arranged near the first inclined plane 1200 of the first material receiving port 1300. The input component 5000 transports the raw materials and finished ores to be transferred to the first receiving part 1000, so that the raw materials and finished ores fall into the first receiving part 1000. During the falling process of the raw materials and finished ores, dust will be generated. The dust-proof cover 5100 will inhibit the dust generation phenomenon. The belt output end 5200 is close to the first inclined plane 1200. When the raw materials on the belt output end 5200 horizontally move from the side and fall into the first receiving part 1000, the raw materials will directly fall on the first inclined plane 1200, facilitating the raw materials to fall into the second receiving part 2000.

[0039] Furthermore, as Figure 4 shown, the second boss 2100 is located below the first inclined plane 1200. The raw materials guided by the first inclined plane 1200 will directly fall on the second boss 2100.

[0040] Preferably, as Figure 6As shown, the third buffer surface 3100 is arc-shaped. The arc-shaped buffer surface further buffers the raw materials falling from the second receiving part 2000, thereby forming a three-stage buffer 8300.

[0041] Preferably, as Figure 3 and Figure 4 shown, the blocking part is L-shaped. The L-shaped blocking part can better retain the raw materials.

[0042] Preferably, as Figure 3 、 Figure 4 and Figure 5 shown, the buffer transfer chute further includes a discharging assembly. The discharging assembly includes a first discharging part 6100 and a second discharging part 6200. The first discharging part 6100 is arranged on the first receiving part 1000, and the second discharging part 6200 is arranged on the second receiving part 2000. When the types of transferred raw materials need to be changed in the overall transportation line, the accumulated raw materials need to be cleaned. In the prior art, manual cleaning is mostly used, which makes personnel enter a relatively enclosed space, posing a certain danger. At this time, by setting the discharging assembly, automatic discharging is realized, reducing the danger to personnel and reducing the labor intensity of personnel.

[0043] Further, as Figure 4 、 Figure 5 and Figure 6 shown, both the first boss 1100 and the second boss 2100 are provided with a discharge plate hole 7000. One end of the first discharging part 6100 communicates with the inner cavity of the first receiving part 1000 through the discharge plate hole 7000, and the other end of the first discharging part 6100 communicates with the outer wall of the first receiving part 1000 near the second material receiving port 2300. One end of the second discharging part 6200 communicates with the inner cavity of the second receiving part 2000 through the discharge plate hole 7000, and at the same time, the other end of the second discharging part 6200 communicates with the outer wall of the second receiving part 2000 near the third material receiving port 3200. Among them, the structures of the first discharging part 6100 and the second discharging part 6200 are the same. The first discharging part 6100 includes a discharge frame 6600, a discharge plate 6300, a first transmission part 6400, a support part 6800 and a second transmission part 6500. One end of the first transmission part 6400 is fixedly connected to the discharge plate 6300, and the other end of the first transmission part 6400 is hinged to the bottom of the first boss 1100. The discharge plate 6300 is arranged on the discharge plate hole 7000 through the first transmission part 6400. The second transmission part 6500 passes through the discharge frame 6600 and cooperates with the first transmission part 6400. The support part 6800 is arranged on the inner wall of the discharge frame 6600. The first transmission part 6400 is provided with a blocking hole 6410, and the support part 6800 is inserted into the blocking hole 6410. As Figure 3As shown, when the first receiving part 1000 and the second receiving part 2000 are in the receiving state, at this time, the discharge plates 6300 in the first discharging part 6100 and the second discharging part 6200 close the discharge plate holes 7000, so that the raw materials can continuously remain in the first storage tank and the second storage tank, thereby forming a primary buffer 8100 and a secondary buffer 8200, which are used to buffer the falling raw materials to prevent the raw materials from breaking. When it is necessary to clean the raw materials in the first storage tank and the second storage tank, Figure 4 The dotted arrows in the figure represent the discharge routes. First, the raw materials in the first storage tank are removed. By controlling the support member 6800 to contract and withdraw from the blocking hole 6410, and then controlling the second transmission member 6500 to rotate counterclockwise to drive the first transmission member 6400 to move, so that the discharge plate 6300 moves counterclockwise, so that the raw materials in the first storage tank are discharged from the discharge plate hole 7000 into the first discharging part 6100. The discharged raw materials are buffered by the discharge buffer surface 6610 in the discharge frame 6600 and guided to the secondary buffer 8200, so that the breakage rate of the raw materials in the first storage tank is small after discharging. After the raw materials in the first storage tank are discharged, because the structures of the first discharging part 6100 and the second discharging part 6200 are the same, the same steps are used to discharge the raw materials in the second storage tank. The discharged raw materials will fall on the third buffer surface 3100 and then be discharged outside the third discharge port 3300 of the third receiving part 3000, which also ensures the integrity of the raw materials in the second storage tank after discharging. In addition, after the storage materials in the first storage tank and the second storage tank are discharged, the second transmission member 6500 rotates clockwise to drive the first transmission member 6400 to rotate, so that the discharge plate 6300 coincides with the discharge plate hole 7000, closing the first receiving part 1000 and the second receiving part 2000.

[0044] Preferably, as Figure 5As shown in the figure, the first transmission member 6400 is fan-shaped. A rack is provided on the arc surface of the first transmission member 6400. The center of the first transmission member 6400 is respectively hinged to the bottoms of the first boss 1100 and the second boss 2100. One end of the fan shape of the first transmission member 6400 is connected to the discharge plate 6300. A blocking hole 6410 is provided at the other end of the fan shape of the first transmission member 6400. The blocking hole 6410 cooperates with the support member 6800. The second transmission member 6500 includes a gear and a servo motor. The gear cooperates with the rack of the first transmission member 6400, and the second transmission member 6500 is close to the other end of the fan shape of the first transmission member 6400. The support member 6800 is driven by a hydraulic cylinder. When the support member 6800 supports the first transmission member 6400, the hydraulic cylinder controls the support member 6800 to extend into the blocking hole 6410 of the first transmission member 6400, restricting the movement of the first transmission member 6400, thereby fixing the position of the discharge plate 6300 on the discharge plate hole 7000 and preventing the raw materials falling into the first storage tank and the second storage tank from falling into the first discharge part 6100 and the second discharge part 6200 through the discharge plate hole 7000. The first transmission member 6400 is fan-shaped and cooperates with the gear of the second transmission member 6500, making the rotation of the first transmission member 6400 smoother.

[0045] Preferably, as Figure 4 and Figure 5 shown, the discharge frames 6600 of the first discharge part 6100 and the second discharge part 6200 are both provided with discharge buffer surfaces 6610. The discharge buffer surfaces 6610 are used to buffer the raw materials discharged from the first storage tank and the second storage tank, preventing the raw materials from falling directly and causing damage.

[0046] Preferably, as Figure 3 and Figure 4 shown, the buffer transfer chute further includes a baffle 6700. The baffle 6700 is arranged at the connection between the other end of the first discharge part 6100 and the outer wall of the first receiving part 1000 close to the second receiving port 2300, and the baffle 6700 is arranged at the connection between the other end of the second discharge part 6200 and the outer wall of the second receiving part 2000 close to the third receiving port 3200. When the first discharge part 6100 and the second discharge part 6200 discharge raw materials, the raw materials will push the baffle 6700 and fall into the next receiving part. When the first discharge part 6100 and the second discharge part 6200 do not discharge raw materials, the baffle 6700 covers the connection due to its own weight, thereby closing the first discharge part 6100 and the second discharge part 6200.
