Description

Technical Field

[0001] The invention relates to the technical field of bulk cargo unloading, and in particular to a bulk cargo smooth loading and unloading auxiliary device used in ports. Background Art

[0002] Bulk cargo refers to granular and block-shaped cargo such as bulk grain, spodumene and coal blocks. When unloading at the port terminal, a receiving funnel is used to assist in smooth loading and unloading. When unloading, the grab bucket grabs the bulk cargo from the ship and moves it to the receiving funnel. The bulk cargo enters from the feed port of the receiving funnel and flows out from the discharge port at its lower end. A belt conveyor is set under the discharge port of the receiving funnel to transfer the bulk cargo.

[0003] However, in the prior art, since the operating environment of the wharf is fully open and the wind force in the area is relatively strong, dust is easily generated during the loading, unloading, transshipment and storage of goods. When the materials are unloaded into the hopper using a rotating bucket, since these bulk goods are inevitably mixed with dust during the production and transportation process, the dust mixed in the bulk goods will escape when they are loaded and unloaded into the hopper, seriously polluting the port environment and affecting normal operations. Since the wharf is close to the water, the air humidity is relatively high, and the floating dust will absorb moisture in the air, and the particles will become moist and the viscosity will increase. These moist dusts will gradually accumulate on various equipment as the air flows. Surfaces, such as metal structural parts of cranes, rollers and idlers of conveyor belts, and housings of electrical control cabinets. After long-term accumulation, the mixture of dust and moisture will corrode the protective coating on the surface of the equipment, destroying the integrity of the coating, and then directly exposing the metal parts to a humid environment, causing rust, which will weaken the structural strength of the equipment, causing increased vibration and noise during equipment operation, accelerated wear of mechanical transmission parts, and reduced overall performance and service life of the equipment, which will not only increase the company's operating costs, but also cause terminal operations to be interrupted due to equipment downtime, seriously affecting the terminal's operating efficiency;

[0004] The common dust removal method at present is to install a vacuum cleaner in the hopper. However, due to the irregular shape of bulk cargo and its close accumulation in the hopper, the gap between dust particles and bulk cargo is narrow. Under the action of gravity, the two squeeze each other, and the vacuum cleaner suction port is difficult to penetrate into the dust area. In addition, the bulk cargo will block the airflow, which greatly reduces the dust collection efficiency, making it difficult to effectively separate the dust and unable to achieve the ideal dust removal effect.

[0005] At the same time, when bulk cargo falls into the conveyor belt, the conveyor belt is transferred and transported over long distances. Due to the influence of wind in the port, large areas of dust are raised, which seriously affects the work of on-site operators. Operators work in a dusty environment for a long time, which causes health damage. In addition, most bulk cargoes require a large cost to separate the dust in the later stage. Summary of the invention

[0006] The object of the present invention is to provide a bulk cargo stable loading and unloading auxiliary device applied to ports, so as to solve the problem that bulk cargo and the dust on its surface cannot be effectively separated.

[0007] The technical solution of the present invention is: a bulk cargo stable loading and unloading auxiliary device applied to ports, a support frame, further comprising a funnel fixedly connected inside the support frame, an outer casing fixedly connected to the outside of the funnel, a material distributing member rotatably connected inside the funnel, two linkage sleeves both rotatably connected to the funnel, an upper convex arc plate slidably connected inside the linkage sleeve, a pressure rod and a transmission rod arranged between the funnel and the outer casing, a one-way transmission gear rotatably connected to the outside of the funnel, a telescopic device fixedly connected to the outside of the funnel, a cam rotatably connected inside the funnel, and two dust suction sleeves fixedly connected to the outside of the funnel. The linkage sleeve and the upper convex arc plate are both located below the material distributing member. The pressure rod is fixedly connected to the bottom of the transmission rod. The transmission rod meshes with the one-way transmission gear. The one-way transmission gear is in contact with the material distributing member. The output end of the telescopic device is fixedly connected to the transmission rod. When the transmission rod moves from the initial position to the set position, the pressure rod drives the upper convex arc plate to rotate through the linkage sleeve. When the transmission rod moves from the set position to the initial position, the material distributing member is driven by the one-way transmission gear to rotate 90 degrees for feeding.

[0008] Further, when the telescopic device is fully retracted, the transmission rod is in the initial position, and the pressure rod is located above the two linkage sleeves and they do not contact. When the telescopic device is fully extended, the transmission rod is in the set position.

[0009] Further, the two linkage sleeves are symmetrical about the central axis of the funnel. The linkage sleeve includes a rotating sleeve rotatably connected inside the funnel, a convex angle shaft fixedly connected to the rotating sleeve and located outside the funnel, a torsion spring connected between the convex angle shaft and the funnel, a straight plate fixedly connected to the rotating sleeve, and a plurality of return springs equidistantly connected between the straight plate and the upper convex arc plate. A limiting hole is formed in the straight plate. The side of the straight plate away from the rotating sleeve is in contact with the bottom of the upper convex arc plate.

[0010] Further, the material distributing member includes a rotating shaft rotatably connected inside the funnel, and a plurality of filter plates fixedly connected to the outside of the rotating shaft at equal angles. One end of the rotating shaft is in contact with the one-way transmission gear.

[0011] Further, the top of the transmission rod is a toothed section, and the tooth number transmission ratio of the toothed section to the one-way transmission gear is four to one.

[0012] Further, the pressure rod includes a round rod fixedly connected to the bottom of the transmission rod, and two arc-shaped pressing blocks fixedly connected to both ends of the round rod. The bottom of the arc-shaped pressing block is an arc surface.

[0013] Furthermore, a driving motor is fixedly provided on the outside of the funnel, and an output end of the driving motor is fixedly connected to a cam. When the upper convex arc plate does not rotate, the cam fits with the top of the upper convex arc plate.

[0014] Furthermore, the bottom of the upper convex arc plate is slidably connected to the inside of the limiting hole, the side of the convex angle shaft close to the arc-shaped pressing block is a pressure surface, and the fitting surface between the pressure surface and the arc-shaped pressing block is set as a curved surface.

[0015] Furthermore, the position where the inside of the funnel fits with the filter plate is divided into a material guide surface and an inner arc surface, the material guide surface and the filter plate have the same inclination, the radius of the inner arc surface is equal to the length of the filter plate, a plurality of dust suction grooves are opened on the funnel, a partition net is arranged in the dust suction groove, the linkage sleeve is located near the dust suction groove opened in the funnel, and a support sleeve is arranged on the outer wall of the funnel.

[0016] Furthermore, the one-way transmission tooth includes a spur gear rotatably connected in a support sleeve, and an arc claw fixedly connected to the spur gear on one side close to the rotating shaft, the arc claw is located inside the rotating shaft, a circular groove is provided at one end of the rotating shaft close to the arc claw, and a plurality of arc spring hooks are arranged at equal angles in the circular groove, and the arc spring hooks are fitted with the arc claw.

[0017] Beneficial effects of the present invention:

[0018] 1. By controlling the transmission rod to move up and down and utilizing the unique one-way transmission mechanism of the one-way transmission teeth, the material dividing piece rotates intermittently. The powder piece rotates 90° each time, so that the concentrated materials in the funnel are placed on the upper convex arc plate in batches. The upper convex arc plate vibrates at a high frequency under the extrusion of the cam, causing the bulk goods to shake, thereby promoting efficient separation of dust and bulk goods. The dust suction sleeve cooperates closely with the external dust suction equipment to achieve uniform dispersion of bulk goods, orderly unloading, efficient feeding and comprehensive dust removal. Moreover, each time the upper convex arc plate cooperates with the cam to process the dust, the concentrated bulk goods can be evenly placed on the upper convex arc plate in batches through the powder piece, avoiding local accumulation of bulk goods on the surface of the upper convex arc plate in a short time. The bulk goods squeezed against each other make it difficult to raise dust, effectively solving the dust pollution problem in the process of bulk cargo loading and unloading at the port, improving loading and unloading efficiency, and reducing equipment loss and operating costs.

[0019] 2. The telescopic device is used as a single driving source to control the transmission rod, and the material dividing parts, linkage sleeves, pressure rods, cams, dust suction sleeves and other components work together to greatly improve the operating stability of the device. The mechanical structure is used to ensure the stable operation of the equipment and the continuous and stable development of dust separation. The failure points caused by too many control links are reduced, the continuity of terminal operations is guaranteed, and the overall operating efficiency is improved. The dust can be quickly captured at the moment it is raised, effectively reducing the dust concentration in the operating area, significantly purifying the port environment, and creating a clean working space for the terminal.

[0020] 3. The bulk goods that enter centrally are evenly dispersed through the material distribution part, avoiding local accumulation that makes it difficult for dust to rise. The upper convex arc plate vibrates at a high frequency under the extrusion of the cam, causing the bulk goods to shake, promoting the efficient separation of dust from the bulk goods. The dust suction sleeve can suck the rising dust at multiple positions, effectively reducing the dust concentration in the operation area, significantly purifying the port environment, creating a clean operation space for the wharf, and improving the overall operation fluency and efficiency.

[0031] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0032] Referring to Figures 1-8 , which is an embodiment of the present invention, there is provided a bulk cargo stable loading and unloading auxiliary device applied to a port, including a support frame 1, and further including a funnel 2 fixedly connected inside the support frame 1, an outer protective shell 3 fixedly connected to the outside of the funnel 2, a material distributing member 4 rotatably connected inside the funnel 2, two linkage sleeves 5 both rotatably connected to the funnel 2, an upper convex arc plate 6 slidably connected inside the linkage sleeve 5, a pressure rod 7 and a transmission rod 8 provided between the funnel 2 and the outer protective shell 3, a one-way transmission gear 9 rotatably connected to the outside of the funnel 2, a telescopic device 10 fixedly connected to the outside of the funnel 2, a cam 11 rotatably connected inside the funnel 2, and two dust suction sleeves 12 fixedly connected to the outside of the funnel 2. The dust suction sleeve 12 is connected to an external dust suction device. The linkage sleeve 5 and the upper convex arc plate 6 are both located below the material distributing member 4. The pressure rod 7 is fixedly connected to the bottom of the transmission rod 8. The transmission rod 8 meshes with the one-way transmission gear 9. The one-way transmission gear 9 is in contact with the material distributing member 4. The output end of the telescopic device 10 is fixedly connected to the transmission rod 8. When the transmission rod 8 moves from the initial position to the set position, the pressure rod 7 drives the upper convex arc plate 6 to rotate through the linkage sleeve 5, and the two spliced upper convex arc plates 6 will separate, so that the material above the upper convex arc plate 6 is no longer supported and thus falls from the bottom of the funnel 2. When the transmission rod 8 moves from the set position to the initial position, the two upper convex arc plates 6 are spliced again, and the material distributing member 4 is driven to rotate 90 degrees for feeding through the one-way transmission gear 9, so that the bulk cargo falls above the upper convex arc plate 6 again, and the upper convex arc plate 6 is vibrated by the cam 11, so that the bulk cargo shakes and no longer fits tightly with the dust.

[0033] Specifically, the output end of the telescopic device 10 extends to push the transmission rod 8 to move from the initial position to the set position. When the transmission rod 8 moves, it drives the one-way transmission gear 9 to rotate by meshing with the one-way transmission gear 9. Since the one-way transmission gear 9 can only perform one-way transmission, the material distributing member 4 remains stationary at this time. At the same time, the pressure rod 7 moves downward with the transmission rod 8, drives the upper convex arc plate 6 to rotate through the linkage sleeve 5, and the two spliced upper convex arc plates 6 gradually separate. The material above the upper convex arc plate 6 loses support and falls from the bottom of the funnel 2 to the belt conveyor. The telescopic device 10 can control the movement of the transmission rod 8, thereby driving the material distributing member 4 to evenly disperse the bulk cargo, avoiding unsmooth unloading caused by local accumulation, and cooperating with the upper convex arc plate 6 to orderly receive and release the bulk cargo, greatly improving the loading and unloading stability. The upper convex arc plate 6 vibrates under the action of the cam 11, so that the bulk cargo is efficiently separated from the dust. At the same time, the dust suction sleeve 12 and the external dust suction device work together to quickly suck the dust in the funnel 2 when the bulk cargo is unloaded, and the dust suction sleeve 12 can suck the dust more effectively.

[0034] Referring to Figures 1-5, when the expander 10 is fully retracted, the transmission rod 8 is in the initial position, and the pressure rod 7 is located above the two linkage sleeves 5 and they do not contact each other. When the expander 10 is fully extended, the transmission rod 8 is in the set position.

[0035] Among them, the expander 10 will stop for a certain period of time after one expansion and contraction, which can be achieved through a timing controller. During the stagnation time of the expander 10, the upper convex arc plate 6 will be continuously squeezed by the cam 11 and move up and down. Therefore, during this time, the bulk cargo and dust can be effectively separated. At the same time, when the expander 10 moves upward, the pressure rod 7 will first separate from the linkage sleeve 5, and then the transmission rod 8 will drive the one-way transmission gear 9, so that the material distribution part 4 conveys the bulk cargo above the upper convex arc plate 6, and at this time the two upper convex arc plates 6 have been joined together.

[0036] Refer to Figures 1-7 , the two linkage sleeves 5 are symmetric about the central axis of the funnel 2. The linkage sleeve 5 includes a rotating sleeve 51 rotatably connected inside the funnel 2, a convex angle shaft 52 fixedly connected to the rotating sleeve 51 and located outside the funnel 2, a torsion spring 53 connected between the convex angle shaft 52 and the funnel 2, a straight plate 54 fixedly connected to the rotating sleeve 51, and a plurality of return springs 55 equidistantly connected between the straight plate 54 and the upper convex arc plate 6. A limiting hole 541 is provided on the straight plate 54. When the upper convex arc plate 6 is pressed and moves downward, the return spring 55 will be compressed. The side of the straight plate 54 away from the rotating sleeve 51 always fits against the bottom of the upper convex arc plate 6, so as to ensure that when the upper convex arc plate 6 moves up and down, the gap between the upper convex arc plate 6 and the straight plate 54 is always closed, preventing bulk cargo from entering. At the same time, when the pressure rod 7 presses the convex angle shaft 52, the torsion spring 53 is rotationally compressed accordingly. When the pressure rod 7 moves back, the torsion spring 53 will cause the rotating sleeve 51 to drive the upper convex arc plate 6 to rotate back, and then the two upper convex arc plates 6 are joined together again.

[0037] Refer to Figures 2-8 , the material distribution part 4 includes a rotating shaft 41 rotatably connected inside the funnel 2, and a plurality of filter plates 42 arranged at equal angles and fixedly connected to the outside of the rotating shaft 41. One end of the rotating shaft 41 is in contact with the one-way transmission gear 9. The top of the transmission rod 8 is a tooth section 801, and the tooth ratio of the tooth section 801 to the one-way transmission gear 9 is four to one. The filter plates 42 can be four. When the tooth section 801 moves once, it will drive the one-way transmission gear 9 to rotate 90 degrees, and then the rotating shaft 41 will drive the filter plates 42 to rotate 90 degrees, so that the material located between the two filter plates 42 falls above the upper convex arc plate 6.

[0038] Refer to Figures 2-6 , the pressure rod 7 includes a round rod 71 fixedly connected to the bottom of the transmission rod 8, and two arc-shaped pressing blocks 72 fixedly connected to both ends of the round rod 71. The bottom of the arc-shaped pressing block 72 is an arc surface. When the transmission rod 8 moves up and down, the round rod 71 will move up and down synchronously.

[0039] Reference Figures 2-6 As shown in Figures 2-6 , a driving motor 14 is fixedly arranged outside the funnel 2, and the output end of the driving motor 14 is fixedly connected to the cam 11. When the upper convex arc plate 6 does not rotate, the cam 11 fits against the top of the upper convex arc plate 6. At this time, when the driving motor 14 drives the cam 11 to rotate, the cam 11 will squeeze the upper convex arc plate 6, causing the upper convex arc plate 6 to move up and down. The bulk cargo above the upper convex arc plate 6 is shaken due to vibration, so that the bulk cargo and the dust are no longer in contact, thus better separating and adsorbing at the same time.

[0040] Reference Figures 2-6 As shown in Figures 2-6 , the bottom of the upper convex arc plate 6 is slidably connected inside the limit hole 541. The side of the convex angle shaft 52 close to the arc-shaped pressing block 72 is the pressure-receiving surface 521, and the fitting surface between the pressure-receiving surface 521 and the arc-shaped pressing block 72 is an arc surface. When the round rod 71 drives the arc-shaped pressing block 72 to move down, the arc-shaped pressing block 72 will first contact the pressure-receiving surface 521, and then the pressure-receiving surface 521 will be pressed and rotated when the arc-shaped pressing block 72 moves down.

[0041] Reference Figures 1-6 As shown in Figures 1-6 , the positions inside the funnel 2 that are in contact with the filter plate 42 are divided into a material guiding surface 21 and an inner arc surface 22. The inclination of the material guiding surface 21 is the same as that of the filter plate 42, ensuring that the bulk cargo can fall between the two filter plates 42. The radius of the inner arc surface 22 is equal to the length of the filter plate 42, so that the bulk cargo inside the filter plate 42 will always be between the filter plates 42 and will not fall when the filter plate 42 does not rotate. A plurality of dust suction grooves 201 are provided on the upper part of the funnel 2, a partition net 13 is arranged inside the dust suction grooves 201, the linkage sleeve 5 is located near the position where the dust suction grooves 201 are provided on the funnel 2, a support sleeve 202 is arranged on the outer wall of the funnel 2, and a plurality of holes are provided on both the upper convex arc plate 6 and the filter plate 42.

[0042] Specifically, a plurality of dust suction grooves 201 are provided, and both the upper and lower parts of the upper convex arc plate 6 are provided with them, so that the dust can be further sucked when the bulk cargo and dust fall. Moreover, the upper convex arc plate 6 protrudes upward, so the upper convex arc plate 6 cannot block the bulk cargo after rotation. At the same time, the holes on the upper convex arc plate 6 and the filter plate 42 can allow the dust to pass through. When the bulk cargo falls, due to the gap between the filter plate 42 and the upper convex arc plate 6, the dust can be better sucked when the bulk cargo falls.

[0043] Reference Figures 1-8 As shown in Figures 1-8 , the one-way transmission gear 9 includes a spur gear 91 rotatably connected inside the support sleeve 202, and an arc claw 92 fixedly connected to the side of the spur gear 91 close to the rotating shaft 41. The arc claw 92 is located inside the rotating shaft 41. A circular groove is provided at one end of the rotating shaft 41 close to the arc claw 92, and a plurality of arc-shaped spring hooks 411 are arranged at equal angles inside the circular groove. The arc-shaped spring hooks 411 are in contact with the arc claw 92.

[0044] Among them, in order to prevent the rotation shaft 41 from rotating, a one-way drive is formed by the arc claw 92 and the arc-shaped spring hook 411. Specifically, there are three arc-shaped spring hooks 411, and the outside of the arc claw 92 also has three arc-shaped claws. There are two rotation directions of the arc claw 92. In one rotation direction, the arc-shaped surface of the arc-shaped claw will squeeze the hook claw of the arc-shaped spring hook 411. As a result, the arc-shaped spring hook 411 will squeeze the spring and contract, and no transmission can be carried out. In the other direction, its hook claw will directly engage with the arc-shaped spring hook 411, thereby realizing one-way drive and ensuring that the material distributing member 4 rotates in the expected direction.

[0045] Specifically, when the transmission rod 8 moves from the initial position to the set position, the tooth section 801 of the transmission rod 8 also drives the one-way transmission gear 9 as a whole to rotate. At this time, the one-way transmission gear 9 cannot be transmitted to the material distributing member 4 due to one-way transmission, and the transmission rod 8 will squeeze the upper convex arc plate 6 through the pressure rod 7, and then separate the assembled upper convex arc plate 6. Subsequently, when the transmission rod 8 moves from the set position to the initial position, the pressure rod 7 no longer squeezes the upper convex arc plate 6. When the transmission rod 8 moves upward again, the material distributing member 4 can be rotated through the one-way transmission gear 9. At this time, the scattered materials in the material distributing member 4 will fall above the upper convex arc plate 6. During the falling process of the bulk goods, the bulk goods and dust will fall synchronously, and the dust will be in a floating state and will be sucked by the dust suction sleeve 12.

[0046] The working principle of the present invention is as follows: When the telescopic device 10 is fully retracted, the transmission rod 8 is in the initial position, the pressing rod 7 is located above the two linkage sleeves 5 and they do not contact each other, and there is a spacing between them. The material distributing member 4 is also stationary. At this time, the two upper convex arc plates 6 are closely joined together. The contour curve on the outside of the cam 11 continuously presses the upper convex arc plate 6, causing the upper convex arc plate 6 to slide inside the limiting hole 541. That is, when the upper convex arc plate 6 moves downward, the return spring 55 is compressed, and then the bulk goods above the upper convex arc plate 6 vibrate due to the vibration effect, and the bulk goods and the dust are no longer closely attached. At this time, the dust suction grooves 201 located above and below the upper convex arc plate 6, in cooperation with the dust suction sleeve 12 and the external dust suction device, continuously suck the floating dust. At the same time, there is a partition net 13 in the dust suction groove 201 to prevent the bulk goods from entering. When the output end of the telescopic device 10 extends out, it pushes the transmission rod 8 to move from the initial position to the set position. The tooth section 801 at the top of the transmission rod 8 meshes with the spur gear 91, driving the spur gear 91 to rotate. The spur gear 91 will drive the arc claw 92 to rotate. However, the arc claw 92 cooperates with the arc-shaped spring hook 411 in the rotating shaft 41. In this rotation direction, at this time, the arc claw 92 cannot drive the rotating shaft 41 to rotate, and the rotating shaft 41 remains stationary. The round rod 71 and the arc-shaped pressing block 72 move downward with the transmission rod 8. The arc surface at the bottom of the arc-shaped pressing block 72 contacts the pressed surface 521 of the convex angle shaft 52. As the transmission rod 8 continues to move downward, the pressed surface 521 is squeezed by the arc-shaped pressing block 72 and rotates, and the convex angle shaft 52 then rotates accordingly, driving the rotating sleeve 51 to rotate at the same time, and the torsion spring 53 will be rotationally compressed. The rotating sleeve 51 is connected to the upper convex arc plate 6 through the straight plate 54, thereby driving the upper convex arc plate 6 to rotate. The two joined upper convex arc plates 6 are separated due to the rotation, and the material above them loses support and falls from the bottom of the funnel 2 onto the belt conveyor. During this process, when the bulk goods fall, they will also be sucked and dust-removed by the dust suction groove 201. When the transmission rod 8 moves to the set position, that is, when the telescopic device 10 is fully extended, the telescopic device 10 will quickly contract, pulling the transmission rod 8 to move from the set position to the initial position. At this time, the pressing rod 7 first separates from the convex angle shaft 52. After the convex angle shaft 52 loses the extrusion, the torsion spring 53 that has been rotationally compressed will rotate back accordingly, causing the rotating sleeve 51 to rotate back, and the two upper convex arc plates 6 will also be joined together again under the action of the torsion spring 53. Subsequently, the tooth section 801 of the transmission rod 8 meshes with the spur gear 91 again, and the spur gear 91 rotates in the reverse direction. In this rotation direction, the arc claw 92 meshes with the arc-shaped spring hook 411, driving the rotating shaft 41 of the material distributing member 4 to rotate by 90 degrees, causing the material located between the two filter plates 42 to fall above the upper convex arc plate 6. Since there is a gap between the filter plate 42 and the upper convex arc plate 6, and the holes on both of them can allow the dust to pass through, the dust is more easily sucked when the bulk goods fall.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
