Description

Technical Field

[0001] The invention relates to the technical field of blockage dredging, and in particular to a tool for dredging blockage in a slide pipe. Background Art

[0002] Belt transportation is one of the most commonly used methods of cargo transportation at this stage. Cargo can be transferred through belt conveyors, and different belts need to be connected through transfer towers. When the belt conveyor is conveying powdered materials, due to the high humidity of the materials, they are easy to gather in the chute of the transfer tower, which leads to blockage. For chute blockage, water flushing is usually used to dredge it. Water flushing is to directly impact the upper end of the chute with tap water through a water pipe. The blocked material can only be dredged when it is completely soaked from the top to the bottom. It is laborious and water-consuming, and the dredging time is long. Therefore, it is very necessary to design a tool to quickly dredge the blockage.

[0003] For example, a water fork for unblocking material in a belt conveyor transfer tower chute with publication number CN222006498U relates to the technical field of belt conveyor auxiliary tools, including: a fork head, which is a hollow structure and has a pointed head at one end, and a water outlet is provided near the pointed end of the fork head so that the high-pressure water flow entering the fork head can be sprayed out through the water outlet; an extension rod, which is a hollow structure and is connected to the fork head at one end; a joint seat, which is provided at the other end of the extension rod and is connected to a pipe for connecting to an external water pipe. This device can quickly clear the accumulated material when the belt conveyor transfer tower chute is blocked. The fork head carries a high-pressure water flow and penetrates deep into the blocked material in the belt conveyor transfer tower chute, promoting the impact of the water flow on the accumulated material below, accelerating the clearing of the accumulated material, reducing the water consumption and reducing the time for clearing the blocked material in the belt conveyor production line. It is simple to operate and greatly improves the clearing efficiency.

[0017] Technical effects and advantages of the present invention: 1. The present invention provides a spherical shell, and a plurality of hard rubber plates are provided on the outside of the spherical shell. The outside of the hard rubber plates is provided with spikes. An end cover is provided on the top of the spherical shell, and a traction chain is provided above the end cover. When the slide pipe is unblocked, the traction chain can be fixed to one end of the slide pipe, and the spherical shell and the hard rubber plate can stay inside the slide pipe under the action of the traction chain. The hard rubber plate can collide with the material through the spikes on the outside thereof, and break up the blocked material to achieve the effect of unblocking the slide pipe.

The present invention arranges a movable cover inside the spherical shell, and the movable cover can rotate with an angle deviation inside the spherical shell. A rotating shaft is arranged inside the movable cover, and a plurality of eccentric wheels are arranged in the middle of the rotating shaft. The eccentric wheels and the rotating shaft can rotate under the drive of a driving motor. When the eccentric wheels and the rotating shaft rotate inside the movable cover, the movable cover rotates under the influence of the precession effect generated by the rotation of the rotating shaft. Since the center of gravity of the eccentric wheel changes continuously during the rotation process, the kinetic energy of the swing is generated. Therefore, the movable cover deviates during the process of being affected by the precession effect. The deviated rotation of the movable cover acts on the spherical shell, causing the spherical shell to vibrate in the chute, thereby improving its dredging effect on the material. 3. The present invention provides an annular groove on the outer side of the spherical shell, and the hard rubber plate is arranged inside the annular groove. By providing clamping grooves at both ends of the annular groove, and arranging clamping blocks on the inner side of the hard rubber plate, the clamping blocks cooperate with the clamping grooves to achieve installation of the hard rubber plate, and the hard rubber plate can play a protective role for the spherical shell. Moreover, when the hard rubber plate is vigorously pushed to deform toward both ends, the clamping blocks and the clamping grooves can be separated, and the hard rubber plate can be quickly disassembled and cleaned.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 10As shown, a tool for clearing blocked material in a chute provided by the present invention is essentially a spherical tool that can drive the material in the chute to vibrate through its own vibration to achieve a clearing effect. The tool mainly comprises a spherical shell 1, a hard rubber plate 3 and a movable cover 4. The spherical structure composed of the spherical shell 1 and the hard rubber plate 3 can be put into the chute and collide with the blocked material in the chute. A rotatable eccentric wheel 42 is arranged inside the movable cover 4. When the eccentric wheel 42 rotates inside the movable cover 4, the movable cover 4 rotates and deflects under the influence of the precession effect. The rotation and deflection of the movable cover 4 inside the spherical shell 1 will cause the spherical shell 1 to vibrate, and the vibration of the spherical shell 1 can act on the blocked material to achieve the effect of conveying the chute. In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment, and no special limitation is made in this embodiment.

[0031] In this embodiment, a tool for clearing blockage in a slide pipe includes: A spherical shell 1, which has a cavity inside and an opening at the top; an annular groove 2, which is arranged on the outer wall of the spherical shell 1; a clamping groove 21, which has an inner cavity of an "L"-shaped structure and is located at the end of the annular groove 2, and a plurality of clamping grooves 21 are provided, and the plurality of clamping grooves 21 are arranged around the edge of the annular groove 2; A hard rubber plate 3, which is provided with a plurality of plates and is installed around the inside of the annular groove 2, and the hard rubber plate 3 can realize the wrapping protection of the spherical shell 1, and both sides of the hard rubber plate 3 are set as arc structures. After being installed in the annular groove 2, the plurality of hard rubber plates 3 fit each other, and the outer surface of the hard rubber plate 3 is flush with the outer surface of the spherical shell 1. The hard rubber plate 3 and the spherical shell 1 can form a complete spherical structure, so that the device can be placed inside the slide pipe; A plurality of spikes 31 are provided and are located on the outside of the hard rubber plate 3. The spikes 31 can collide with the material; The upper slot 22 and the lower slot 23 are respectively located at the two ends of the inner side wall of the annular groove 2, and the clamping block 32 is set to an "L"-shaped structure corresponding to the clamping slot 21 and is located at the inner side wall end of the hard rubber plate 3. The clamping block 32 cooperates with the clamping slot 21 to fix the position of the hard rubber plate 3; Insert blocks 33, which are located at both ends of the hard rubber plate 3 and are adapted to the upper slot 22 and the lower slot 23; The movable cover 4 has an arc-shaped outer surface and is located inside the spherical shell 1. The movable cover 4 is used to rotate inside the spherical shell 1 and drive the spherical shell 1 to jump through the precession effect to achieve the effect of clearing the blockage; A rotating shaft 41 is located inside the movable cover 4 and is rotatably connected to the middle of the inner wall of the movable cover 4 through a bearing. A plurality of eccentric wheels 42 are provided and are located in the middle of the rotating shaft 41. The widths of the two ends of the eccentric wheels 42 are different. When the rotating shaft 41 drives the eccentric wheels 42 to rotate, an oblique force is generated due to the misalignment between the center of the eccentric wheels 42 and the rotating shaft 41, and the movable cover 4 is driven to move. A driving motor 43 is located inside the movable cover 4. The output shaft of the driving motor 43 is transmission-connected to the middle of the rotating shaft 41 through a bevel gear set 44. The driving motor 43 is fixedly mounted on one end of the inner part of the movable cover 4 through a bracket, and a matching storage battery is provided at one end of the driving motor 43; The guide groove 5 is set to an annular structure and has an arc-shaped inner wall. The movable cover 4 can slide inside the guide groove 5. The slide seat 6 is located on the outer side of the movable cover 4 and is connected to the outer side wall of the movable cover 4 through a connecting rod 61. The slide seat 6 can slide along the inner wall of the guide groove 5. The guide groove 5 can limit the movement range of the slide seat 6, thereby limiting the movement range of the movable cover 4; The end cover 7 is located in the opening at the top of the spherical housing 1. The outer wall of the end cover 7 is flush with the outer wall of the spherical housing 1. The end cover 7 and the spherical housing 1 can form a complete spherical structure. The circular groove 71 is located inside the opening at the top of the spherical housing 1. The end cover 7 is plugged and installed inside the circular groove 71. The mounting hole 72 is located on the upper surface of the end cover 7. The mounting hole 72 is provided with bolts for fixing the position of the end cover 7 and the circular groove 71. The end cover 7 can be removed by removing the bolts to release the limit of the end cover 7, so that the end cover 7 can be removed to facilitate the battery matching the drive motor 43 to be charged. The traction chain 8 is located at the middle of the top of the end cover 7. The traction chain 8 is used to pull the end cover 7 and the spherical shell 1 to prevent the spherical shell 1 from moving with the material. The end of the traction chain 8 can be equipped with a hook or other fixing part to facilitate the positioning of the device.

[0032] When using a tool for clearing blocked material in a chute of the present embodiment, one end of the traction chain 8 is fixed above the chute, and then the spherical shell 1 is dropped into the chute. The spherical structure composed of the spherical shell 1 and the hard rubber plate 3 can collide with the blocked material in the chute to realize the transportation of the material. The driving motor 43 can drive the rotating shaft 41 to rotate through the bevel gear set 44, and the rotating shaft 41 can drive the eccentric wheel 42 to rotate. Since the center of gravity of the eccentric wheel 42 is misaligned with the rotating shaft 41, when the eccentric wheel 42 rotates inside the rotating shaft 41, the movable cover 4 swings due to the shift of the center of gravity of the eccentric wheel 42. In this process, the movable cover 4 drives the slide seat 6 to move, so that the slide seat 6 moves inside the guide groove 5, so that the movable cover 4 swings inside the spherical shell 1. At the same time, the rotation of the eccentric wheel 42 and the rotating shaft 41 will produce a precession effect, so that the movable cover 4 rotates inside the spherical shell 1. The rotation and swinging of the movable cover 4 inside the spherical shell 1 will cause the spherical shell 1 to vibrate, and the vibration of the spherical shell 1 will act on the blocked material to achieve the effect of dredging the material. The hard rubber plate 3 on the outside of the spherical shell 1 can play a protective role for the spherical shell 1, and the spikes 31 on the outside of the hard rubber plate 3 can enhance the vibration effect of the device on the material, so as to achieve the effect of improving the dredging efficiency of the device. When disassembling and replacing the hard rubber plate 3, first insert the plug 33 at the bottom end of the hard rubber plate 3 into the lower slot 23, and insert the card block 32 at the bottom end of the hard rubber plate 3 into the corresponding card slot 21, and then pull the top end of the hard rubber plate 3 to deform the top end of the hard rubber plate 3 outward. At this time, the top end of the hard rubber plate 3 is The upper card block 32 is moved to move so that the upper card block 32 is away from the lower card block 32. At this time, the upper card block 32 has enough space to be inserted into the corresponding card slot 21, and then the top of the hard rubber plate 3 is pressed so that the plug block 33 at the top of the hard rubber plate 3 is deformed under the extrusion and inserted into the upper slot 22, and the installation of the hard rubber plate 3 is completed. When removing the hard rubber plate 3, use a flat-head wrench, a pry plate or other tools to pry the top of the hard rubber plate 3 to deform it until the card block 32 is separated from the card slot 21, and the removal of the hard rubber plate 3 can be achieved.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
