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; 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. 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.

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.

[0016] 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.

[0017] 3. The bulk cargo entering in concentrated form is evenly dispersed through the material dividing parts to avoid local accumulation that makes it difficult to raise dust. The upper convex arc plate vibrates at a high frequency under the extrusion of the cam, causing the bulk cargo to shake, thereby promoting efficient separation of dust and bulk cargo. The dust suction sleeve can absorb the raised dust at multiple positions, effectively reducing the dust concentration in the operating area, significantly purifying the port environment, creating a clean operating space for the terminal, and improving the smoothness and efficiency of the overall operation.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figure 1-Figure 8, as an embodiment of the present invention, a bulk cargo smooth loading and unloading auxiliary device applied to a port is provided, comprising a support frame 1, a funnel 2 fixedly connected to the inside of the support frame 1, an outer protective shell 3 fixedly connected to the outside of the funnel 2, a material dividing member 4 rotatably connected to the inside of the funnel 2, two linkage sleeves 5 are provided and both are rotatably connected to the funnel 2, an upper convex arc plate 6 slidably connected to the inside of the linkage sleeve 5, a pressure rod 7 and a transmission rod 8 arranged between the funnel 2 and the outer protective shell 3, a one-way transmission tooth 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 to the inside of 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 at the dividing member. Below the material piece 4, the pressure rod 7 is fixedly connected to the bottom of the transmission rod 8, the transmission rod 8 is meshed with the one-way transmission tooth 9, the one-way transmission tooth 9 is fitted with the material dividing piece 4, and 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 plates 6 is no longer supported, so that the bottom of the funnel 2 falls, and 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 one-way transmission tooth 9 drives the material dividing piece 4 to rotate ninety degrees for feeding, so that the bulk goods fall into the upper part of the upper convex arc plate 6 again, and the upper convex arc plate 6 will be squeezed and vibrated by the cam 11, so that the bulk goods shake and no longer fit tightly with the dust.

[0022] The cam 11 is used to move the upper convex arc plate 6 and the lower convex arc plate 6 is used to move the upper convex arc plate 6.

[0023] Reference Figure 1-Figure 5 When the telescopic device 10 is fully retracted, the transmission rod 8 is located at the initial position, and the pressure rod 7 is located above the two linkage sleeves 5 and the two are not in contact. When the telescopic device 10 is fully extended, the transmission rod 8 is located at the set position.

[0024] Among them, the telescopic device 10 will stop for a certain period of time after one extension and contraction, which can be controlled by a timing controller. During the stagnation time of the telescopic device 10, the upper convex arc plate 6 will be continuously squeezed by the cam 11 and move up and down, and then during this time, the bulk goods and dust can be effectively separated. At the same time, when the telescopic device 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 tooth 9, so that the material dividing piece 4 will transport the bulk goods to the top of the upper convex arc plate 6, and at this time the two upper convex arc plates 6 have been spliced.

[0025] Reference Figure 1-7 The two linkage sleeves 5 are symmetrical about the central axis of the funnel 2. The linkage sleeve 5 includes a rotating sleeve 51 rotatably connected to the inside of 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 is equidistantly connected to the upper convex arc plate 6. When the pressure rod 7 is pressed against the convex angle shaft 52, the torsion spring 53 is rotated and compressed. When the pressure rod 7 moves back, the torsion spring 53 causes the rotating sleeve 51 to drive the upper convex arc plate 6 to rotate, and then the two upper convex arc plates 6 are assembled again.

[0026] Reference Figure 2-Figure 8 The material dividing member 4 includes a rotating shaft 41 rotatably connected to the inside of 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 tooth 9. The top of the transmission rod 8 is a tooth segment 801. The transmission ratio of the number of teeth of the tooth segment 801 and the one-way transmission tooth 9 is four to one. There are four filter plates 42 shells, so that after the tooth segment 801 moves once, it will drive the one-way transmission tooth 9 to rotate ninety degrees, and then the rotating shaft 41 drives the filter plate 42 to rotate ninety degrees, so that the material between the two filter plates 42 falls to the top of the upper convex arc plate 6.

[0027] Reference Figure 2-Figure 6 The pressure rod 7 includes a round rod 71 fixedly connected to the bottom of the transmission rod 8, and two arc-shaped pressure blocks 72 fixedly connected to the two ends of the round rod 71. The bottom of the arc-shaped pressure 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.

[0028] Reference Figure 2-Figure 6A driving motor 14 is fixedly provided on the outside of 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 is not rotating, the cam 11 is in contact with 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, so that the upper convex arc plate 6 moves up and down, and the bulk cargo above the upper convex arc plate 6 shakes due to the vibration, so that the bulk cargo and the dust are no longer in contact with each other, thereby better separating and adsorbing them at the same time.

[0029] Reference Figure 2-Figure 6 The bottom of the upper convex arc plate 6 is slidably connected to the inside of the limiting hole 541, and the side of the convex angle shaft 52 close to the arc pressure block 72 is a pressure surface 521. The fitting surface between the pressure surface 521 and the arc pressure block 72 is set as an arc surface. When the round rod 71 drives the arc pressure block 72 to move downward, the arc pressure block 72 will first contact the pressure surface 521, and then the pressure surface 521 will be compressed and rotated when the arc pressure block 72 moves downward.

[0030] Reference Figure 1-Figure 6 The position where the funnel 2 fits with the filter plate 42 is divided into a guide surface 21 and an inner arc surface 22. The guide surface 21 and the filter plate 42 have the same inclination to ensure 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 in the filter plates 42 will always be between the filter plates 42 and will not fall when the filter plates 42 are not rotated. A plurality of dust suction grooves 201 are provided on the funnel 2, and a partition net 13 is provided in the dust suction groove 201. The linkage sleeve 5 is located near the dust suction groove 201 of the funnel 2. A support sleeve 202 is provided on the outer wall of the funnel 2, and a plurality of hole grooves are provided on the upper convex arc plate 6 and the filter plate 42.

[0031] Specifically, a plurality of dust suction grooves 201 are provided, and the upper convex arc plate 6 is opened at the upper and lower parts, so that the dust of the bulk cargo can be further absorbed when it falls, and the upper convex arc plate 6 is convex upward, so the upper convex arc plate 6 cannot block the bulk cargo after rotation, and at the same time, the holes and grooves on the upper convex arc plate 6 and the filter plate 42 can allow dust to pass through, and when the bulk cargo falls, due to the gap between the filter plate 42 and the upper convex arc plate 6, the dust of the bulk cargo can be better absorbed when it falls.

[0032] Reference Figure 1-8 The one-way transmission tooth 9 includes a spur gear 91 rotatably connected to the inside of the support sleeve 202, and an arc claw 92 fixedly connected to the spur gear 91 on the side 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. A plurality of arc spring hooks 411 are arranged at equal angles in the circular groove. The arc spring hooks 411 fit the arc claw 92.

[0033] In order to avoid driving the rotating shaft 41 to rotate, the arc claw 92 and the arc spring hook 411 are used to form a one-way transmission. Specifically, three arc spring hooks 411 are provided, and the outside of the arc claw 92 is also three arc claws. The arc claw 92 has two rotation directions. In one rotation direction, the arc surface of the arc claw will squeeze the hook claw of the arc spring hook 411, and the arc spring hook 411 will squeeze the spring to contract, making it impossible to transmit. In the other direction, the hook claw will directly engage with the arc spring hook 411, thereby realizing one-way drive and ensuring that the material dividing piece 4 rotates in the expected direction.

[0034] Specifically, when the transmission rod 8 moves from the initial position to the set position, the tooth segment 801 of the transmission rod 8 also drives the one-way transmission tooth 9 to rotate as a whole. At this time, the one-way transmission tooth 9 cannot be transmitted to the material dividing piece 4 due to the 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 up again, the one-way transmission tooth 9 can be used to rotate the material dividing piece 4. At this time, the scattered goods in the material dividing piece 4 will fall above the upper convex arc plate 6, and on the way of the bulk goods falling, 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.

[0035] 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 pressure rod 7 is located above the two linkage sleeves 5 and the two are not in contact, and there is a distance between the two, and the material dividing piece 4 is also stationary. At this time, the two upper convex arc plates 6 are tightly assembled, and the outer contour curve of the cam 11 continuously squeezes the upper convex arc plate 6, so that the upper convex arc plate 6 slides inside the limiting hole 541, that is, when the upper convex arc plate 6 moves downward, the return spring 55 is compressed, and the bulk cargo above the upper convex arc plate 6 is shaken by the vibration, and the bulk cargo is no longer tightly fitted with the dust. At this time, the dust suction groove 201 located above and below the upper convex arc plate 6 cooperates with the dust suction sleeve 12 and the external suction The dust collecting device continuously absorbs the floating dust. At the same time, there is a partition net 13 in the dust collecting groove 201 to prevent bulk goods from entering. 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. The tooth segment 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, but the arc claw 92 cooperates with the arc spring hook 411 in the rotating shaft 41. In this rotation direction, the arc claw 92 cannot drive the rotating shaft 41 to rotate. The rotating shaft 41 remains stationary, and the round rod 71 and the arc pressure block 72 move downward with the transmission rod 8. The arc surface at the bottom of the arc pressure block 72 contacts the pressure surface 521 of the convex angle shaft 52. The rod 8 continues to move downward, and the pressure surface 521 is squeezed and rotated by the arc-shaped pressure block 72, and the convex angle shaft 52 then rotates accordingly, driving the rotating sleeve 51 to rotate, and the torsion spring 53 will be compressed by the rotation, and 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 spliced ​​upper convex arc plates 6 are separated due to the rotation, and the materials above them lose support and fall from the bottom of the funnel 2 to the belt conveyor. In this process, the bulk goods will also be sucked and dusted by the dust suction groove 201 when they fall. 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 shrink rapidly, pulling the transmission rod 8 from the set position to the initial position. At this time , the pressure rod 7 is first separated from the convex angle shaft 52. After the convex angle shaft 52 loses its extrusion, the rotated and compressed torsion spring 53 will rotate accordingly, causing the rotating sleeve 51 to rotate. The two upper convex arc plates 6 are also reassembled under the action of the torsion spring 53, and then the tooth segment 801 of the transmission rod 8 is meshed with the spur gear 91 again, and the spur gear 91 rotates in the opposite direction. In this rotation direction, the arc claw 92 and the arc spring hook 411 are meshed with each other, driving the rotating shaft 41 of the material dividing member 4 to rotate ninety degrees, so that the material between the two filter plates 42 falls to the top of 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 and grooves on the two allow dust to pass through, the dust is easier to be absorbed when the bulk cargo falls.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
