Description

Technical Field

[0001] The utility model relates to the technical field of telescopic chutes, in particular to a telescopic chute for a ship loader. Background Art

[0002] The telescopic chute is one of the important parts of the ship loader. It is used to discharge bulk materials into the ship's cabin. When the ship loader needs to transport materials from land to the ship, the telescopic chute is stretched to the side of the ship, and the materials are smoothly moved to the ship through the telescopic chute. However, today's telescopic chutes are unable to effectively slow down the materials when discharging them, causing the materials to fall too fast, which can easily cause the materials to break and generate a lot of dust. In severe cases, the cabin may even be damaged due to the large impact force of the materials on the cabin. Utility Model Content

[0003] The utility model discloses a telescopic chute for a ship loader, which solves the problem that when the telescopic chute discharges materials, the material falls too fast, which easily causes the materials to break and generates large dust, and even causes damage to the cabin in serious cases.

[0004] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0005] A telescopic chute for a ship loader comprises an upper cylinder and a lower cylinder, wherein a telescopic cylinder is connected between the upper cylinder and the lower cylinder, a sealing cylinder is detachably connected to the bottom of the lower cylinder, a group of discharge pipes are connected to the lower cylinder, a connecting ring located above the discharge pipes is fixed to the lower cylinder, a lifting rope is fixed to the connecting ring; a funnel-shaped cover cylinder which covers the sealing cylinder is detachably connected to the bottom of the connecting ring, and a fixedly connected dust cover is sleeved on the cover cylinder.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The height of the lower cylinder can be adjusted by the hanging rope so that the lower cylinder compresses or stretches the telescopic cylinder. When the material enters the telescopic cylinder through the upper cylinder, it is discharged into the lower cylinder and then into the sealing cylinder. When the material accumulates in the sealing cylinder to a certain height corresponding to the discharge pipe, the material can be discharged through the discharge pipe; at this time, the feeding amount of the material entering the upper cylinder is greater than the sum of the discharge amounts of a group of discharge pipes. When the material slowly accumulates in the lower cylinder and is slightly higher than a group of discharge pipes, the feeding amount of the material entering the upper cylinder can be made the same as the sum of the discharge amounts of a group of discharge pipes; when the material enters the upper cylinder and After entering the lower cylinder through the telescopic cylinder, it falls on the top of the material, which effectively cushions the falling material. Then the material opposite to the lower pipe is discharged into the cover cylinder through the lower pipe. After the cover cylinder collects the materials together, it is discharged into the cabin. The dust cover can effectively block the dust generated by the materials falling in the cabin. The utility model can effectively cushion the falling materials, avoid the materials directly hitting the cabin and being broken or generating large dust, and the materials will not generate a large impact force on the inside of the cabin, thereby avoiding damage to the inside of the cabin.

DETAILED DESCRIPTION

[0013] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , Figure 2 and Figure 4As shown, the utility model provides a telescopic chute for a ship loader, comprising an upper tube 1 and a lower tube 3, wherein a telescopic tube 2 is connected between the upper tube 1 and the lower tube 3, a sealing tube 31 is detachably connected to the bottom of the lower tube 3, a group of discharge pipes 32 are connected to the lower tube 3, a connecting ring 5 located above the discharge pipes 32 is fixed to the lower tube 3, a lifting rope 51 is fixed to the connecting ring 5; a funnel-shaped cover tube 6 which covers the sealing tube 31 and is detachably connected to the bottom of the connecting ring 5, a fixedly connected dust cover 61 is sleeved on the cover tube 6.

[0015] like Figure 1 and Figure 3 As shown, the upper cylinder 1 is sleeved with a fixed ring 11, a telescopic rod 52 is fixed between the connecting ring 5 and the upper cylinder 1, and a through hole is opened on the fixing ring 11 for the lifting rope 51 to pass through, and both sides of the lifting rope 51 are provided with a limiting wheel 12 installed on the top of the fixing ring 11. The lifting rope 51 is driven by a driving device on the ship loader. When the driving device reels or unwinds the lifting rope 51, the lifting rope 51 and the limiting wheel 12 produce friction, and then the limiting wheel 12 can be rotated. The setting of the limiting wheel 12 can limit the lifting rope 51 and prevent the lifting rope 51 from rubbing against the inner wall of the perforation on the fixing ring 11; after the lifting rope 51 moves, it can drive the lower cylinder 3 to move upward or downward through the connecting ring 5, so that the telescopic cylinder 2 is compressed or stretched, and the telescopic cylinder 2 adopts a corrugated cylinder; the number of the telescopic rods 52 is at least two and a three-section telescopic rod is adopted. The setting of the two telescopic rods 52 is to prevent the telescopic cylinder 2 from shaking when the lower cylinder 3 moves upward or downward.

[0016] like Figure 1 and Figure 2 As shown, the sealing cylinder 31 is provided with a movable ring 4 that can be raised and lowered, and a spring 41 connected to the bottom of the sealing cylinder 31 is fixed at the bottom of the movable ring 4, and a vertical pipe 42 that penetrates the bottom of the sealing cylinder 31 is connected to the bottom of the movable ring 4; a sealing cap 43 is threadedly connected to the bottom of the vertical pipe 42, and a vertical rod 44 extending to the outside of the cover cylinder 6 is fixed to the bottom of the sealing cap 43. When the material enters the upper cylinder 1 and falls downward, the material falls on the movable ring 4, and the movable ring 4 drives the vertical pipe 42 to move downward to compress the spring 41, which plays a buffering role for the material; when all the materials are loaded in the cabin, the sealing cap 43 can be rotated by the vertical rod 44, and the bottom of the vertical pipe 42 can be opened to discharge the materials in the sealing cylinder 31.

[0017] like Figure 1 , Figure 2 and Figure 4 As shown, the inner ring surface of the moving ring 4 is concave; the lower cylinder 3 and the sealing cylinder 31 are both fixed with a fixing block 45, and the fixing blocks 45 on the lower cylinder 3 and the sealing cylinder 31 are fixed by bolts. The inner ring surface of the moving ring 4 is concave, which can effectively prevent the material from accumulating on the top of the moving ring 4, so that the material can be discharged through the vertical pipe 42.

[0018] like Figure 2 As shown, a symmetrical inclined plate 33 is fixed inside the lower cylinder 3, and the inclined plate 33 is inclined toward the axis of the lower cylinder 3. A rubber block 34 connected to the inner wall of the lower cylinder 3 is fixed to the bottom surface of the inclined plate 33. When the material enters the lower cylinder 3, it first contacts the top surface of the inclined plate 33. The inclined plate 33 can effectively buffer the material and prevent the material from directly hitting the moving ring 4; the rubber block 34 can increase the firmness of the connection between the inclined plate 33 and the inner wall of the lower cylinder 3.

[0019] like Figure 1 As shown, a connection block 62 is fixed on the top of the cover tube 6, and an opening for the connection block 62 to pass through is opened on the connection ring 5. The connection block 62 is fixed to the connection block 62 by screws; a bearing plate 63 in contact with the bottom surface of the sealing tube 31 is fixed inside the cover tube 6. After the staff removes the screws, the connection block 62 is separated from the connection ring 5 to facilitate the inspection of the cover tube 6 and the dust cover 61. At the same time, the lower tube 3 and the sealing tube 31 can be separated by removing the bolts on the fixing block 45 to facilitate the inspection of the parts in the sealing tube 31; the bearing plate 63 can increase the firmness of the connection between the sealing tube 31 and the lower tube 3.

[0020] During use, after the material enters the upper cylinder 1, it can enter the lower cylinder 3 through the telescopic cylinder 2, and then enter the sealing cylinder 31. After the material is accumulated in the sealing cylinder 31, as the material height increases, when the material is relative to a group of discharge pipes 32, it can be discharged through the discharge pipes 32; at this time, the feed amount of material entering the upper cylinder 1 is greater than the sum of the discharge amounts of a group of discharge pipes 32, so that the material accumulated in the lower cylinder 3 exceeds the discharge pipes 32, then the feed amount of material entering the upper cylinder 1 can be the same as the sum of the discharge amounts of a group of discharge pipes 32, and when the subsequent material enters the lower cylinder 3, it falls on the top of the material accumulated in the lower cylinder 3, which can effectively buffer the material, and the material corresponding to the discharge pipe 32 can be discharged into the cover cylinder 6 through the discharge pipe 32, and then discharged into the cabin, and the dust cover 61 can effectively block the dust generated by the material falling in the cabin.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
