Description

Technical Field

[0001] The invention belongs to the technical field of ship loaders, and in particular relates to a spiral chute of a ship loader. Background Art

[0002] The spiral chute of the ship loader is an important component of loading equipment, mainly used to transport bulk materials (such as sand and grain, etc.) from land to the cargo hold of the ship. It is usually composed of a long metal pipe with a rotating spiral installed inside. The bulk materials are transported from the storage area to the cargo hold of the ship through the rotation of the spiral. The use of the spiral chute of the ship loader can greatly improve the loading efficiency, which is more efficient and faster than traditional manual or mechanical loading. It can transport a large amount of bulk materials in a short time and is suitable for large-scale ship loading operations.

[0003] When transporting bulk materials, the spiral chute is prone to accumulation and agglomeration due to the characteristics of the bulk materials or factors such as humidity, which can lead to uneven material transportation and even blockage of the chute, affecting the normal operation of the equipment. When existing spiral chutes are blocked, the most common way to deal with it is to shut down the machine and perform maintenance and cleaning. Operators will ensure that after the equipment stops running, they can safely enter the chute for cleaning according to the equipment's safe operating procedures, which includes clearing the blocked materials and removing the agglomerates to restore the normal operation of the chute. In some cases, the blocked materials can also be pushed out of the chute mouth by rotating the spiral chute in the opposite direction, but this method is usually suitable for situations where the blockage is relatively light. In addition, these two methods not only have large limitations in use and low safety, but also delay the transportation efficiency of bulk materials such as sand and gravel. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a spiral chute for a ship loader.

[0005] The technical solution adopted to solve the above technical problems is: a spiral chute of a ship loader, including a spiral chute shell, an upper mounting seat fixedly connected to the upper end of the spiral chute shell, a connecting seat fixedly installed on the lower surface of the upper mounting seat, a lower mounting seat fixedly connected to the lower end of the spiral chute shell, a spiral driving mechanism is arranged at the upper end of the spiral chute shell; a spiral feeding rod is fixedly installed at the lower end of the spiral driving mechanism, a rotating feeding mechanism is installed at the lower end of the spiral chute shell, a movable limiting mechanism is fixedly installed on the inner wall of the rotating feeding mechanism, and vibration mechanisms are symmetrically installed on both sides of the spiral chute shell.

[0006] Through the above technical solution, the spiral feeding rod can not only rotate to feed the material, but also vibrate the blocked bulk material off or push it out from the edge of the spiral feeding rod through reciprocating linear motion. This movement helps to destroy and disperse the blocked sand and gravel, making it easier to be washed away by the bulk material flow in the chute.

[0007] Furthermore, a discharge pipe port is fixedly installed on the upper end of the spiral chute shell, a mounting connection frame is installed on one side of the upper mounting seat, a plurality of fixed mounting holes are evenly opened on the mounting connection frame, and an anti-blocking mechanism is installed on the upper end of the inner wall of the spiral chute shell.

[0010] Through the above technical solution, the output end of the second motor can drive the driving gear to rotate, and the driving gear drives the second driven gear to rotate through meshing, and the threaded rod moves toward the adjustment disk to push one end of the adjustment disk, so that the adjustment disk is inclined at an angle. At this time, the mounting disc is affected by the motion state of the adjustment disc when it rotates following the power connecting shaft, so that the mounting disc can drive the spiral feeding rod to move linearly while rotating through the power connecting shaft.

[0011] Furthermore, the spiral drive mechanism includes a driving shaft rotatably connected to the upper mounting seat, the upper end of the driving shaft is fixedly connected to a first driven gear, one side of the first driven gear is meshed with a driving gear, a mounting groove is provided in the upper mounting seat, a first motor is fixedly installed in the mounting groove, an output end of the first motor is fixedly connected to the driving gear, an upper plug-in groove is provided at the lower end of the driving shaft, a first connecting column is slidably connected in the upper plug-in groove, a first sliding protrusion is fixedly connected to the outer side of the first connecting column, a power connecting shaft is fixedly installed at the lower end of the first connecting column, and the power connecting shaft is fixedly connected to the spiral feeding rod.

[0012] Through the above technical solution, the output end of the first motor can drive the driving gear to rotate, and the driving gear drives the first driven gear to rotate by meshing with the first driven gear, thereby causing the driving shaft to rotate. Since the upper plug-in groove and the first sliding protrusion are engaged with each other, the first sliding protrusion and the power connecting shaft can rotate synchronously. Furthermore, the spiral loading rod can rotate to transport the sand and gravel in the connecting cylinder upward.

[0013] Furthermore, the rotary feeding mechanism includes a sliding ring rotatably connected to the lower mounting seat, the sliding ring is fixedly mounted to the fixed frame, a connecting tube is installed at the lower end of the fixed frame, a plurality of feed ports are opened on the circumference of the connecting tube, and feed frames are installed correspondingly on the outer sides of the plurality of feed ports, and the feed frame is fixedly connected to the connecting tube.

[0014] Through the above technical solution, the connecting cylinder drives multiple feed frames to rotate evenly when rotating, so that the bulk material is quickly shoveled into the connecting cylinder through the feed port and transported by the spiral feeding rod. In this way, the bulk material can be quickly and continuously introduced into the chute, thereby improving the feeding efficiency of the ship loader.

[0015] Furthermore, the movable limiting mechanism includes a positioning column fixedly connected to the inner wall of the connecting cylinder, the upper end of the positioning column is fixedly connected to a connecting shaft, the upper end of the connecting shaft is fixedly connected to a second connecting column, the outer side of the second connecting column is fixedly connected to a second sliding protrusion, the lower end of the spiral feeding rod is provided with a lower plug-in groove, the lower plug-in groove and the second sliding protrusion are slidingly connected, the lower surface of the spiral feeding rod is fixedly connected to a limiting rod, the outer side of the limiting rod is provided with a limiting groove, the limiting groove is slidably connected to a limiting seat, the limiting seat is fixedly connected to the positioning column, and a return spring is sleeved on the outer side of the connecting shaft.

[0016] Through the above technical solution, when the spiral feeding rod moves downward, the limit rod pushes the return spring downward to compress. When the spiral feeding rod has an upward movement tendency, the return spring can push the limit rod to drive the spiral feeding rod to move upward, and so on. Therefore, while the spiral feeding rod rotates to feed the material, it can also vibrate the blocked bulk material or push it out from the edge of the spiral feeding rod through reciprocating linear motion, thereby avoiding long-term accumulation and blockage, maintaining smooth transportation in the spiral chute shell, and ensuring continuous transportation of bulk materials.

[0017] Furthermore, the vibration mechanism includes a vibration shell, the front and rear ends of the vibration shell are fixedly connected to positioning shafts, the two positioning shafts are respectively fixedly connected to the lower mounting seat and the upper mounting seat, a vibration chamber is provided in the vibration shell, a central shaft is rotatably connected between the front and rear ends of the inner wall of the vibration shell, an eccentric cam block is fixedly connected to the outer wall of the central shaft, a driving wheel is fixedly installed at one end of the outer wall of the central shaft, a third motor is installed in the vibration chamber, an output shaft is fixedly connected to the output end of the third motor, a driven wheel is fixedly connected to the output shaft, and a transmission belt is installed between the driven wheel and the driving wheel.

[0018] Through the above technical scheme, the output shaft of the third motor can drive the driving wheel, the center shaft and the eccentric cam block to rotate synchronously through the driven wheel and the transmission belt. When the center shaft and the eccentric cam block rotate at high speed, they can generate uniform vibration, and transmit the vibration to the spiral chute shell through the vibration shell. The high-frequency vibration transmitted to the inner wall of the spiral chute shell can make the sand and gravel in the spiral chute quickly and evenly dispersed.

[0019] Furthermore, the third motor is fixedly connected to the inner wall of the vibration shell, and the vibration shell has an arc surface on one side close to the outer shell of the spiral chute.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention adopts a vibration mechanism, and the central shaft and the eccentric cam block can generate uniform vibration when rotating at high speed, and transmit the vibration to the outer shell of the spiral chute through the vibration shell. The high-frequency vibration transmitted to the inner wall of the outer shell of the spiral chute can make the sand and gravel in the spiral chute quickly and evenly dispersed, effectively prevent the accumulation of bulk materials in the chute, maintain the uniform flow of bulk materials, and make the bulk materials more smoothly transported in the chute, thereby reducing the problem of reduced transportation efficiency caused by the blockage of bulk materials, and further reducing the problem of blockage that may occur in the spiral chute during use; (2) The present invention adopts a spiral The cooperation between the rotary drive mechanism, the anti-blocking mechanism, the movable limiting mechanism and the spiral feeding rod enables the spiral feeding rod to rotate and feed while at the same time vibrating and dropping the blocked bulk material or pushing it out from the edge of the spiral feeding rod through reciprocating linear motion. This motion helps to destroy and disperse the blocked sand and gravel, making it easier for it to be washed away by the bulk material flow in the chute. Therefore, the stability of the feeding process can be maintained, and transportation interruptions or unevenness caused by local blockages can be avoided, thereby avoiding long-term accumulation and blockage, maintaining smooth transportation in the outer shell of the spiral chute, ensuring continuous transportation of bulk materials, and improving the transportation efficiency of sand and gravel bulk materials.

A mounting groove 24 is provided in the upper mounting seat 11, and a first motor 25 is fixedly installed in the mounting groove 24. The output end of the first motor 25 is fixedly connected to the driving gear 23, and an upper plug-in groove 26 is provided at the lower end of the driving shaft 21, and a first connecting gear 23 is slidably connected in the upper plug-in groove 26. Column 27, a first sliding protrusion 28 is fixedly connected to the outer side of the first connecting column 27, a power connecting shaft 29 is fixedly installed at the lower end of the first connecting column 27, the power connecting shaft 29 is fixedly connected to the spiral feeding rod 3, and the output end of the first motor 25 can drive the driving gear 23 to rotate, and the driving gear 23 drives the first driven gear 22 to rotate by engaging with the first driven gear 22, thereby rotating the driving shaft 21. Since the upper plug-in groove 26 and the first sliding protrusion 28 are engaged with each other, the first sliding protrusion 28 and the power connecting shaft 29 can rotate synchronously. Furthermore, the spiral feeding rod 3 can rotate to transport the sand and gravel in the connecting cylinder 50 upward.

[0037] like Figure 1-Figure 10As shown, the rotating feeding mechanism 5 includes a sliding ring 54 rotatably connected to the lower mounting seat 16, the sliding ring 54 is fixedly installed on the fixed frame 53, and a connecting cylinder 50 is installed at the lower end of the fixed frame 53.

The feed frame 52 is fixedly connected to the connecting cylinder 50. When the connecting cylinder 50 rotates, it drives the plurality of feed frames 52 to rotate evenly, so that the bulk material is quickly shoveled into the connecting cylinder 50 through the feed port 51 and transported by the spiral feeding rod 3. In this way, the bulk material can be quickly and continuously introduced into the chute, thereby improving the feeding efficiency of the ship loader; the movable limiting mechanism 6 includes a positioning column 60 fixedly connected to the inner wall of the connecting cylinder 50, the upper end of the positioning column 60 is fixedly connected to a connecting shaft 62, the upper end of the connecting shaft 62 is fixedly connected to a second connecting column 63, the outer side of the second connecting column 63 is fixedly connected to a second sliding protrusion 64, and the spiral A lower plug-in groove 68 is provided at the lower end of the screw-in material rod 3, and the lower plug-in groove 68 is slidably connected with the second sliding protrusion 64.

The limit slide groove 67 is slidably connected with a limit seat 61, and the limit seat 61 is fixedly connected to the positioning column 60. A return spring 65 is sleeved on the outer side of the connecting shaft 62. When the spiral feeding rod 3 moves downward, the limit rod 66 pushes the return spring 65 downward to be compressed. When the spiral feeding rod 3 has an upward movement trend, the return spring 65 can push the limit rod 66 to drive the spiral feeding rod 3 to move upward, and thus reciprocate, so that the spiral feeding rod 3 can rotate and feed at the same time, and can also vibrate and drop the blocked bulk material or push it out from the edge of the spiral feeding rod 3 through reciprocating linear motion, thereby avoiding long-term accumulation and blockage, maintaining smooth transportation in the spiral chute shell 1, and ensuring continuous transportation of bulk material.

[0038] like Figure 1-Figure 12As shown, the vibration mechanism 7 includes a vibration shell 70, the front and rear ends of the vibration shell 70 are fixedly connected to positioning shafts 71, the two positioning shafts 71 are respectively fixedly connected to the lower mounting seat 16 and the upper mounting seat 11, a vibration chamber 72 is provided in the vibration shell 70, a central shaft 73 is rotatably connected between the front and rear ends of the inner wall of the vibration shell 70, an eccentric cam block 74 is fixedly connected to the outer wall of the central shaft 73, a driving wheel 75 is fixedly installed at one end of the outer wall of the central shaft 73, a third motor 79 is installed in the vibration chamber 72, an output shaft 78 is fixedly connected to the output end of the third motor 79, a driven wheel 77 is fixedly connected to the output shaft 78, and a driven wheel 77 is fixedly connected to the driven wheel 77. A transmission belt 76 is installed between the rotating wheel 77 and the driving rotating wheel 75. The output shaft 78 of the third motor 79 can drive the driving rotating wheel 75, the central shaft 73 and the eccentric cam block 74 to rotate synchronously through the driven rotating wheel 77 and the transmission belt 76. When the central shaft 73 and the eccentric cam block 74 rotate at high speed, they can generate uniform vibration, and transmit the vibration to the spiral chute shell 1 through the vibration shell 70. The high-frequency vibration transmitted to the inner wall of the spiral chute shell 1 can make the sand and gravel in the spiral chute quickly and evenly dispersed; the third motor 79 is fixedly connected to the inner wall of the vibration shell 70, and the vibration shell 70 is a circular arc surface on the side close to the spiral chute shell 1.

[0039] The working principle of this embodiment is as follows: the connecting cylinder 50 at the lower end of the spiral chute is placed in the sand and gravel bulk material that needs to be transported into the ship, and the first motor 25 is started. The output end of the first motor 25 drives the driving gear 23 to rotate, and the driving gear 23 drives the first driven gear 22 to rotate by meshing with the first driven gear 22, thereby rotating the driving shaft 21. Since the upper plug-in groove 26 and the first sliding protrusion 28 are engaged with each other, the first sliding protrusion 28 and the power connecting shaft 29 can rotate synchronously. Further, the spiral feeding rod 3 can rotate to transport the sand and gravel in the connecting cylinder 50 upward;

[0040] At the same time, the second sliding protrusion 64 is plugged into the lower plug-in groove 68, so that the spiral feeding rod 3 can drive the connecting cylinder 50 to rotate through the second connecting column 63, and the connecting cylinder 50 drives the multiple feeding frames 52 to rotate evenly when rotating, so that the bulk materials are quickly shoveled into the connecting cylinder 50 through the feeding port 51 and transported by the spiral feeding rod 3;

[0041] When the feeding work starts in the spiral chute, the third motor 79 will start working synchronously. The output shaft 78 of the third motor 79 can drive the driving wheel 75, the central shaft 73 and the eccentric cam block 74 to rotate synchronously through the driven wheel 77 and the transmission belt 76. When the central shaft 73 and the eccentric cam block 74 rotate at high speed, they can generate uniform vibration, and transmit the vibration to the spiral chute shell 1 through the vibration shell 70. The high-frequency vibration transmitted to the inner wall of the spiral chute shell 1 can make the sand and gravel in the spiral chute quickly and evenly dispersed, effectively prevent the accumulation of bulk materials in the chute, maintain the uniform flow of bulk materials, and make the bulk materials more smoothly transported in the chute, reducing the problem of reduced transportation efficiency caused by bulk material blocking;

[0042] When the spiral feeding rod 3 is blocked by sand and gravel and cannot move, the second motor 46 is started, and the output end of the second motor 46 drives the driving gear 45 to rotate, and the driving gear 45 drives the second driven gear 47 to rotate through meshing, and the threaded rod 48 moves toward the adjustment disk 41 to push one end of the adjustment disk 41, so that the adjustment disk 41 is inclined. At this time, the installation disk 44 is affected by the movement state of the adjustment disk 41 when it rotates with the power connection shaft 29, so that the installation disk 44 can drive the spiral feeding rod 3 while rotating through the power connection shaft 29. The screw feeding rod 3 performs linear motion. When the screw feeding rod 3 moves downward, the limit rod 66 pushes the return spring 65 downward to compress. When the screw feeding rod 3 has an upward movement trend, the return spring 65 can push the limit rod 66 to drive the screw feeding rod 3 to move upward, and so on. As a result, the screw feeding rod 3 can rotate and feed at the same time. At the same time, it can also vibrate and drop the blocked bulk material or push it out from the edge of the screw feeding rod 3 through the reciprocating linear motion, thereby avoiding long-term accumulation and blockage, maintaining smooth transportation in the spiral chute shell 1, and ensuring continuous transportation of bulk material.
