Description

Technical Field

[0001] The present application relates to the technical field of vibration conveying, and in particular to a device for transporting various building materials. Background Art

[0002] Gravel, ore, and sand are commonly used construction materials in engineering projects. The above materials are often transported by vibrating conveyors. During the vibrating conveying process, due to the difference in the volume of material particles, the use of an open vibrating carrier will cause the material particles to fall out of the vibrating carrier from the open space above the vibrating carrier. Continuously lifting the side walls of the vibrating carrier can reduce the occurrence of rockfall.

[0003] Ore is often used as filling material in earthwork projects. Due to its larger particle size, it bounces higher during vibration transportation. Raising the side wall of the transport carrier will increase the weight of the carrier itself and increase the load on the vibration motor. The closed carrier usually uses a long-axis circular tube. Since there is no open space around the circular tube, it can effectively solve the problem of falling rocks.

[0004] When the ore moves in a closed circular tube, it may block the tube. Since the circular tube itself is usually made of some non-transparent metal or non-metal material, it is difficult to determine the location of the blockage when blockage occurs inside the circular tube, thereby increasing the cost of cleaning and unblocking the blockage.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-8 This application is described in further detail.

[0030] The present application embodiment discloses a device for transporting various building materials. Figure 1 The vibration machine anti-rockfall conveying device includes a vibration tube 1 for conveying materials. The vibration machine includes a support frame and a vibration motor, and the vibration motor is used to provide vibration power for the vibration tube 1. The vibration tube 1 has an inclination angle with the horizontal direction, so that the material in the vibration tube 1 can move from the inlet at the upper end of the vibration tube 1 to the outlet at the lower end under the action of its own gravity.

[0031] The vibrating tube 1 is provided with a positioning mechanism for detecting the location of the material blockage and a dredging mechanism for clearing the blocked material. Except for sulfide ores, most ores contain magnetic components such as iron, cobalt, nickel, iron oxide, and ferroferric oxide, which can reduce the adsorption and friction between the blocked materials by magnetic attraction, thereby achieving the purpose of clearing the blockage.

[0032] Reference Figure 1 and Figure 2 The positioning mechanism includes a set of contact switches 2 arranged along the axial direction of the vibration tube 1. Preferably, the contact switch 2 is arranged at the top of the inner circumference of the vibration tube 1; when the material is blocked, the height of the blocked material will gradually increase. When the blocked material contacts the contact switch 2 on the top surface of the vibration tube 1, the switch will be triggered, and the positioning mechanism will be triggered.

[0033] Reference Figure 2 The contact switch 2 includes a plurality of switch slots 21 which are straightly provided on the inner circumference of the vibration tube 1, and a contact member 22 which is radially slidably provided in the switch slots 21 along the vibration tube 1. The side wall of the contact member 22 is fixedly connected with a limit plate 23, and the side wall of the switch slot 21 is provided with a limit plate 24 for accommodating the limit plate 23; the limit plate 23 is vertically slidably provided in the limit plate 24 to prevent the contact member 22 from escaping from the switch slot 21. A limit spring 25 is vertically fixedly provided in the limit slot 24, and the top end of the limit spring 25 is fixedly provided with the limit plate 23 to provide elastic force for the contact member 22 to reset downward. A switch moving plate 26 is fixedly provided on the top surface of the contact member 22, and a switch fixed plate 1 which can be in electrical contact with the switch moving plate 26 is fixedly provided on the top surface of the switch slot 21.

[0034] After the vibration tube 1 is clogged with material, the clogged material gradually piles up and contacts the contact piece 22 located at the top of the inner circumference of the vibration tube 1; the clogged material exerts upward pressure on the contact piece 22, and causes the contact piece 22 to move upward against the elastic force of the limit spring 25, so that the switch moving piece 26 is in electrical contact with the switch fixed piece 1. Since each group of contact switches 2 is a position switch, when at least one group of contact switches 2 is closed, it indicates that the corresponding position is clogged with material.

[0035] Reference Figure 2 , baffles 41 for preventing accidental touch are slidably arranged on the opposite side walls in the switch slot 1 21. Specifically, a slide slot 1 62 is provided on the inner wall of the switch slot 1 21, and the baffle 41 is slidably arranged in the slide slot 1 62 along the radial direction of the vibration tube 1; the slide slot 1 62 is arranged on the side wall adjacent to the limit slot 24. A limit spring 2 11 is fixedly connected in the slide slot 1 62, and the end of the limit spring 2 11 is fixedly connected to the baffle 41, which is used to provide elastic force for the baffle 41 to move toward the outside of the slide slot 1 62. When the limit spring 11 is in a naturally extended state, the baffle 41 is located above the contact piece 22; the bottom corners of the two baffles 41 on the opposite sides are respectively provided with chamfers 12 that can contact the top corners of the contact piece 22. When the baffles 41 are pressed and move upward, the top corners of the baffles 41 can push the two baffles 41 to move to both sides respectively; when the baffles 41 are pressed and retracted into the slide groove 62, the contact piece 22 moves upward and contacts the switch stator 1.

[0036] Due to the vibration of the vibration tube 1 itself and the accidental contact of the material in the vibration tube 1 with the contact piece 22 during the continuous vibration process, the contact piece 22 will shrink toward the inside of the switch slot 21. The baffle 41 can offset part of the instantaneous pressure on the contact piece 22 under the elastic force of the limit spring 211, thereby slowing down the movement of the contact piece 22. When the contact piece 22 contacts the blocking material, the blocking material applies continuous pressure to the contact piece 22, causing the contact piece 22 to push the baffle 41 away and move upward.

[0037] Reference Figure 3 , the dredging mechanism includes a support ring 3 that moves along the axial direction of the vibration tube 1, and the center of the support ring 3 is colinear with the axial direction of the vibration tube 1. The support ring 3 has a plurality of magnetic axes 8 evenly distributed along its own circumference; the magnetic axes 8 are all electromagnets, and the plurality of magnetic axes 8 are connected in series. The discharge port of the vibration tube 1 is fixedly connected with a discharge pipe extending downward; the initial position of the support ring 3 is located between the discharge pipe and the bottom end of the vibration tube 1 to avoid blocking the movement of the material in the vibration tube 1. At least one set of driving components for driving the support ring 3 to move is arranged in the vibration tube 1. The driving component includes a guide groove 31 opened on the inner side wall of the vibration tube 1 along the axial direction of the vibration tube 1 and a lead screw 32 rotatably arranged in the guide groove 31; the end of the lead screw 32 is connected to a stepping motor to provide moving power for the lead screw 32. Two sets of driving components arranged in opposite positions can be arranged in the vibration tube 1, or a rod or shaft for guiding can be arranged at the opposite position of the driving component, so as to provide a guiding effect for the movement of the support ring 3.

[0038] Reference Figure 3 and Figure 4 , guide members 4 are fixed on both sides of the support ring 3, and the guide members 4 are slidably arranged in the guide groove 31 along the axial direction of the vibration tube 1. The guide member 4 is a hollow box body; a partition plate 1 is fixed horizontally along the length direction of the guide member 4, dividing the space in the guide member 4 into a chamber 1 43 located above and a chamber 2 located below. A partition plate 2 is fixed vertically along the length direction of the chamber 2, dividing the space in the chamber 2 into a chamber 3 away from the support ring 3 and a chamber 4 45 close to the support ring 3. The lead screw 1 32 is arranged through the chamber 3.

[0039] Reference Figure 4 , a partition plate 3 is vertically fixed in the chamber 3 along the width direction of the guide member 4, dividing the space in the chamber 3 into a chamber 5 44 close to the stepping motor and a chamber 6 42 far from the stepping motor. A threaded ring 5 is rotatably arranged in the chamber 6 42; when the threaded ring 5 is limited, the lead screw 1 32 and the threaded ring 5 are threadedly matched to drive the guide member 4 to move along the length direction of the vibration tube 1; when the threaded ring 5 loses its limiting function, the threaded ring 5 rotates with the lead screw 1 32, and the guide member 4 stops moving.

[0040] Reference Figure 4, a through hole 51 is provided on the partition plate 2 to connect the chamber 4 45 and the chamber 6 42. A plug-in piece 52 is slidably arranged in the through hole 51 along the width direction of the guide member 4; a plug-in hole 53 is provided on the outer peripheral surface of the threaded ring 5 to be plugged into the plug-in piece 52; the plug-in piece 52 provides a limiting function for the threaded ring 5. A guide piece 54 is fixed to the side wall of the plug-in piece 52, and a guide groove 14 for accommodating the guide piece 54 is provided on the side wall of the through hole 51. The guide piece 54 is slidably arranged in the guide groove 14 along the width direction of the guide member 4. A compression spring 155 is fixed in the guide groove 14, and the end of the compression spring 155 is connected to the guide piece 54, which is used to provide an elastic force for the guide piece 54 to return to the side away from the threaded ring 5. When the plug-in piece 52 is subjected to the pressure from the chamber four 45, the plug-in piece 52 can be plugged into the threaded ring 5. When the pressure in the chamber four 45 disappears, the plug-in piece 52 is separated from the threaded ring 5 under the action of the compression spring one 55.

[0041] Reference Figure 4 , a slider 6 is slidably arranged in the chamber four 45 along the length direction of the guide member 4. A connecting hole 61 that can accommodate the slider 6 is provided in the direction of the chamber four 45 away from the stepping motor. A compression spring 2 is fixed to the side wall of the slider 6, which is used to drive the slider 6 to reset to the outside of the chamber four 45. A contact groove 63 that can be plugged with the plug-in piece 52 is provided on the side wall of the slider 6 close to the chamber six 42. A chamfer 2 is provided at the end of the plug-in piece 52 away from the connecting hole 61. When the plug-in piece 52 is plugged with the contact groove 63, the plug-in piece 52 and the threaded ring 5 are in a separated state; when the slider 6 moves to the outside of the connecting hole 61, the plug-in piece 52 contacts the side wall of the abutment groove 63 away from the connecting hole 61 through the chamfer 2, and is pressed to move in the direction close to the threaded ring 5 and plugged with the threaded ring 5; then the end of the plug-in piece 52 abuts against the side wall of the slider 6, and the other end remains plugged with the threaded ring 5.

[0042] Reference Figure 3 , Figure 5 and Figure 6, the side wall of the guide groove 31 is evenly distributed with a number of receiving grooves 7; preferably, each receiving groove 7 is located on a circular plane with the same axial direction as a switch groove 21 of the vibration tube 1. A stopper 71 is provided in the receiving groove 7 to slide radially along the vibration tube 1. A compression spring 3 72 is fixedly connected to the bottom of the receiving groove 7, and the end of the compression spring 3 72 is fixedly connected to the stopper 71, which is used to drive the stopper 71 to retract to the inside of the receiving groove 7. A magnet 15 is fixedly connected to the side wall of the receiving groove 7. The magnet 15 is an electromagnet, and the magnet 15 is electrically connected to the switch moving piece 26; a metal sheet that can be adsorbed by the magnet 15 is fixedly connected to the side wall of the stopper 71. After the switch moving piece 26 is in electrical contact with the switch fixed piece 1, the stopper 71 is adsorbed by the magnet 15 and moves to the outside of the receiving groove 7 and extends into the guide groove 31; after the moving guide member 4 contacts the stopper 71, the slider 6 contacts the stopper 71 and is pressed to move to the inside of the chamber 4 45. The side wall of the stopper 71 is provided with a receiving groove for accommodating the lead screw 32 to avoid interference between the stopper 71 and the lead screw 32 .

[0043] Each magnet 15 is connected in series with a group of contact switches 2. When the contact switches 2 are closed, the magnets 15 on the same circular plane as the group of contact switches 2 are energized and drive the block 71 to move; the block 71 contacts the moving slider 6 and moves the slider 6; after the slider 6 moves, the plug-in piece 52 is plugged into the abutment groove 63 on the side wall of the slider 6, so that the plug-in piece 52 is separated from the threaded ring 5, so as to stop the guide member 4 from moving. Since the group of blockers 71 is located at the position of the blocked material, the support ring 3 stops moving at the position of the blocked material, and the subsequent dredging operation is carried out.

[0044] Reference Figure 3 , a sliding ring 81 is provided on the support ring 3 along its own axial direction for sliding movement; specifically, a plurality of guide shafts 82 are fixedly provided on the end surface of the support ring 3 along its own circumference, a plurality of guide holes 16 are opened on the sliding ring 81 along its own circumference, and the guide holes 16 are slidably connected to the guide shaft 82; and a stopper 17 is fixedly connected to the end of the guide shaft 82 to prevent the sliding ring 81 from being separated. A plurality of magnetic shafts 8 are fixedly connected to the end surface of the sliding ring 81.

[0045] Reference Figure 4 , a gear column 84 is rotatably arranged in the chamber 5 44. A slide groove 2 83 is provided on the circumference of the lead screw 1 32 along its own axial direction; the gear column 84 is sleeved on the circumference of the lead screw 1 32, and a connecting piece is fixed on the inner circumference of the gear column 84 and is slidably arranged in the slide groove 2 83, so that the gear column 84 can slide with the lead screw 1 32 and can rotate with the lead screw 1 32. A transmission gear 1 73 meshing with the gear column 84 is rotatably arranged on the end surface of the slider 6 located in the chamber 4 45; during the sliding process of the slider 6, the transmission gear 1 73 and the gear column 84 remain in meshing state.

[0046] Reference Figure 4 and Figure 7, a transmission gear 2 74 is rotatably arranged on the inner wall of the chamber 4 45 near the stepping motor. A plurality of meshing teeth 75 are evenly distributed along the circumference of the end surface of the transmission gear 1 73 near the transmission gear 2 74, and a plurality of meshing grooves are evenly distributed along the circumference of the end surface of the transmission gear 2 74 near the transmission gear 1 73, and the meshing teeth 75 can be plugged into the meshing grooves. After the slider 6 is pressed to move toward the inside of the chamber 4 45, the transmission gear 1 73 contacts the transmission gear 2 74, and is connected to the meshing grooves through the meshing teeth 75, thereby driving the transmission gear 2 74 to rotate through the gear column 84.

[0047] Reference Figure 4 , a transmission gear three 91 meshing with the transmission gear two 74 is rotatably provided on the inner wall of the chamber one 43. A lead screw two 92 is rotatably provided in the chamber one 43 along the length direction of the guide member 4; the transmission gear three 91 is sleeved on the circumference of the lead screw two 92, and the transmission gear three 91 is fixedly connected to the lead screw two 92. A threaded member 93 that cooperates with the threaded transmission of the lead screw two 92 is fixedly connected to the circumference of the sliding ring 81. The lead screw two 92 is a reciprocating lead screw, and the lead screw two 92 drives the threaded member 93 to reciprocate along the axial direction of the support ring 3. A switch movable plate two is fixedly connected to the side wall of the slider 6, and the switch movable plate two is electrically connected to the magnetic shaft 8; a switch stator two that can electrically contact the switch movable plate two is fixedly connected to the inner wall of the chamber four 45, and the switch stator two is electrically connected to the power supply.

[0048] Preferably, a driven gear 1 64 is provided between the transmission gear 3 91 and the transmission gear 2 74, for connecting the transmission gear 3 91 and the transmission gear 2 74. The driven gear 2 is rotatably embedded in the partition 2, and the driven gear 2 can be a cylindrical gear, and the driven gear 2 is used to connect the gear column 84 and the transmission gear 1 73.

[0049] When the slider 6 contacts the stopper 71 and moves toward the inside of the chamber 4 45 under pressure, the switch moving piece 2 contacts the switch fixed piece 2 electrically, so that the magnetic shaft 8 is energized; after the magnetic shaft 8 is energized, it can produce an adsorption effect on the ore. After the slider 6 moves, the gear column 84 drives the transmission gear 3 91 to rotate, and the lead screw 2 92 rotates and drives the sliding ring 81 to reciprocate. Since the sliding ring 81 has moved to the material blocking position, the magnetic shaft 8 absorbs the blocking material; the magnetic shaft 8 is driven to reciprocate by the sliding ring 81, reducing the adsorption effect between the blocking material particles.

[0050] Reference Figure 8, an on-off switch for controlling the circuit path and a current switch for changing the direction of the current are arranged between the stepper motor and the power supply.
