Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, in particular to bulk material conveying equipment. Background Art

[0002] Grain refers to the general term for various plant seeds used in cooking food. Bulk grain can be transported to the corresponding area through automated conveying equipment during transfer and transportation, such as transporting grain out of the warehouse to the transport vehicle. Many conveying equipment now can perform automatic and intelligent transportation. During the transportation process, since bulk grain contains a large amount of impurities and dust, and there is a height difference between the discharge port and the transport vehicle, the dust and fine impurities in the bulk grain will float into the air to form dust.

[0003] The existing invention patent with patent publication number CN118289531A discloses dust suppression equipment for yard material transportation, which installs a buffer cloth cover on the drop between the discharge port and the transport vehicle. When bulk grain falls from the discharge port to the transport vehicle, it will pass through the dust removal pipe and the buffer cloth cover. When the bulk grain moves in the buffer cloth cover, it will continuously hit the buffer cloth cover and cause the buffer cloth cover to deform. Under the buffering effect of the buffer cloth cover, the speed at which the bulk grain falls on the transport vehicle is reduced, avoiding the return dust caused by the bulk grain falling onto the transport vehicle at high speed, and can effectively prevent dust from floating in the space, playing a role in dust suppression.

[0004] However, this invention still has the following problems: conical blocks are set in the dust removal pipe to disperse bulk grains, and then the grains gather under the conical blocks and are dispersed by the next conical blocks. However, since the bulk grains continuously enter the dust removal pipe, although they are dispersed by the conical blocks, the bulk grains will still gather under the conical blocks, and the conical blocks occupy a large space inside the dust removal pipe, which can easily cause the bulk grains to block the dust removal pipe. If the conveying speed of the bulk grains is reduced, the conveying efficiency of the grains will be affected. Summary of the Invention

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 3 As shown, the present invention provides bulk material conveying equipment, including a conveying device 1 for conveying materials, a frame 2 is provided at the end of the conveying device 1, a rotating device 3 is provided on the frame 2, an annular bracket 4 connected to the frame 2 is connected to the rotating device 3, a plurality of dispersed screening structures 5 are evenly arranged around the center of the annular bracket 4, a guide groove plate 8 connected to the annular bracket 4 is provided between two adjacent dispersed screening structures 5, and the guide groove plate 8 is used to guide the grain to be dispersed into the corresponding two dispersed screening structures 5 when the conveying device 1 is transferred between two adjacent dispersed screening structures 5, a dust collection structure 6 connected to the annular bracket 4 is commonly provided at the bottom of the multiple dispersed screening structures 5, a shaking structure 7 is commonly connected to the multiple dispersed screening structures 5, and the shaking structure 7 is provided on the frame 2.

[0026] When the present application is in use, the grain is transported to the top of the annular bracket 4 through the conveying device 1, and at the same time the rotating device 3 drives the annular bracket 4 to drive the multiple dispersed screening structures 5 to rotate, so that the multiple dispersed screening structures 5 pass through the lower position of the conveying end of the conveying device 1 in turn, and the multiple dispersed screening structures 5 receive part of the grain in turn, and shake themselves (the dispersed screening structure 5) through the shaking structure 7 during the rotation, so as to screen the dust in the grain into the dust collecting structure 6. After the screening is completed, the dispersed screening structure 5 releases the internal grain, thereby avoiding the occurrence of dust during the grain transportation process.

[0027] At the same time, the two adjacent dispersed screening structures 5 are connected by providing a guide slot plate 8 to prevent the grains transported by the transport device 1 from falling between the two adjacent dispersed screening structures 5 .

[0028] Multiple dispersed screening structures 5 receive part of the grain respectively, avoiding the problem of blockage of the dispersed screening structure 5 due to continuous grain transportation, and multiple dispersed screening structures 5 cyclically screen and release the grain, ensuring the normal transportation of the grain. There is no need to reduce the transportation speed of the conveying device 1, avoiding affecting the transportation efficiency of the grain.

[0029] In this embodiment, the conveying device 1 and the rotating device 3 are both existing technologies. For example, the conveying device 1 can be the conveying channel disclosed in the invention patent with patent publication number CN118289531A (dust suppression equipment for yard material transportation). The two have the same functions, or other conveying equipment can also be used, as long as the grain can be normally transported to the dispersed screening structure 5. The rotating device 3 can be a motor-driven gear, the gear is engaged with the annular bracket 4, or other technical solutions can also be used, which will not be elaborated here.

[0030] The dispersed screening structure 5 includes a screening bin 501 which is rotatably set on the annular bracket 4 and connected to the shaking structure 7. The bottom of the screening bin 501 can screen the dust in the grain. The guide groove plate 8 guides the grain to the top of the screening bin 501. A discharge port is provided on the screening bin 501, and the discharge port is set on the side of the screening bin 501 away from the center of the annular bracket 4. A bin door 503 that can be opened movably is provided at the discharge port by rotating through a torsion spring. An electromagnet 507 for attracting the bin door 503 is provided on the frame 2. The bin door 503 can open the screening bin 501 at a preset position through the magnetic force of the electromagnet 507.

[0031] After the grain enters the screening bin 501, the screening bin 501 is driven by the rotating device 3 and the shaking structure 7, so that the screening bin 501 rotates up and down continuously while rotating around the center of the annular bracket 4, so that the grain moves back and forth in the screening bin 501, thereby generating a shaking effect to screen the grain, and the screened dust enters the dust collecting structure 6. When the screening bin 501 moves to the electromagnet 507, the magnetic attraction bin door 503 of the electromagnet 507 rotates outward, thereby opening the screening bin 501. Since the screening bin 501 is in a rotating state, under the action of centrifugal force, the grain is released from the screening bin 501 to the corresponding area outside through the discharge port. After the screening bin 501 is away from the electromagnet 507, the bin door 503 automatically resets under the action of gravity and the elastic force of the torsion spring to close the screening bin 501.

[0032] The screening bin 501 includes a bottom plate 504 which is rotatably connected to the annular bracket 4 through a torsion spring. A plurality of screening holes 505 are provided on the bottom plate 504 for dust to pass through. A plurality of guard plates 506 are vertically arranged on the bottom plate 504, and the plurality of guard plates 506 are connected in sequence to form a U-shaped plate. The discharge port is the opening of the U-shaped plate, and the discharge port is away from the center of the annular bracket 4. The bin door 503 is arranged at the top of the U-shaped plate, and together with the U-shaped plate, it limits the grain from leaving the bottom plate 504.

[0033] The grain passes through the screening holes 505 on the bottom plate 504 to separate the dust into the dust collecting structure 6. During the rotation of the bottom plate 504, the shaking structure 7 drives the movement, so that the bottom plate 504 rotates around the connection with the annular bracket 4 and compresses the torsion spring, thereby causing the bottom plate 504 and the U-shaped plate composed of multiple guard plates 506 to rotate back and forth. The grain moves back and forth on the bottom plate 504 and is dispersed and screened multiple times, ensuring the dust removal effect of the grain. After the dust removal structure, the bin door 503 rotates under the adsorption of the electromagnet 507 to open the discharge port, that is, the opening of the U-shaped plate, and the grain is released from the discharge port by centrifugal force.

[0034] The side of the bottom plate 504 close to the center of the annular support 4 and the side away from the center of the annular support 4 are both concentric arcs.

[0035] Both sides of the bottom plate 504 are arc-shaped, so that the grain maintains a movement path of the same length under the action of radial centrifugal force, and when the grain is released from the bottom plate 504 away from the center of the annular bracket 4, the length of the path of the grain moving outward due to centrifugal force is the same (theoretically the same, but in reality it is not the same due to the squeezing between grain particles), so the grain can be completely released to the outside of the bottom plate 504 within the same length of time, avoiding the need to drive the bottom plate 504 to rotate multiple times to completely release the grain after the grain transportation is completed.

[0036] The two side walls between the two arc-shaped side walls on the bottom plate 504 are both planar, and when the bottom plate 504 is parallel to the annular bracket 4 , the two planar side walls on the bottom plate 504 pass through the center of the annular bracket 4 .

[0037] That is, the curvature of the side of the bottom plate 504 away from the center of the annular bracket 4 is different from that of the side toward the center of the annular bracket 4. The grain will move from the side of the bottom plate 504 with a longer arc length to the side with a shorter arc length, or from the side with a shorter arc length to the side of 504 with a longer arc length. The width of the bottom plate 504 (the arc length along the circumference of the annular bracket 4) changes, so that the grains will be squeezed or dispersed against each other, thereby causing the grains to move more on the bottom plate 504, thereby improving the dust treatment effect in the grains.

[0038] The dust collection structure 6 includes a plurality of collection boxes 601 which are obliquely arranged on the annular bracket 4 and have open tops. The bottom of the collection box 601 is inclined, and the top opening of each collection box 601 is respectively covered on the outer side of the corresponding base plate 504. Each collection box 601 is provided with a collection port on the side facing the annular bracket 4. The plurality of collection ports are commonly connected to a tubular dust collecting channel 603 with a closed bottom, and a guide pipe 604 is connected to the tubular dust collecting channel 603.

[0039] The dust at the screening site enters the collection box 601 through the screening holes 505, and enters the tubular dust collection channel 603 from the collection port of the collection box 601 for unified collection, and then passes through the guide pipe 604 to the designated area for collection and treatment.

[0040] A plurality of elastic strips 605 are provided on the inner side wall of the collection box 601, and slots 606 extending to the bottom plate 504 are provided on the two opposite guard plates 506. A paddle 607 is provided in the middle position of the bottom of each slot 606, and the slot 606 is for the corresponding elastic strip 605 to enter.

[0041] During the rotation of the screening bin 501, the elastic strip 605 enters the slot 606 and is blocked by the paddle 607. At this time, the elastic strip 605 is deformed. When the elastic strip 605 passes the paddle 607, it recovers its deformation and shakes to drive the collection box 601 to vibrate, thereby helping the dust at the bottom of the collection box 601 to fall faster into the tubular dust collection channel 603.

[0042] The shaking structure 7 includes an annular mounting frame 701 arranged on the frame 2 and located below the annular bracket 4. The top of the annular mounting frame 701 is wavy, and a roller 702 for rolling on the annular mounting frame 701 is provided on the guard plate 506 through a connecting plate.

[0043] The roller 702 and the guard plate 506 are connected by a connecting plate, so that the screening bin 501 drives the roller 702 to move synchronously during the rotation, so that the roller 702 moves along the top of the annular mounting frame 701, and the wavy annular mounting frame 701 drives the roller 702 to move up and down through the reciprocating cycle, so that the guard plate 506 rotates upward under the drive of the connecting plate and resets under the elastic force of the torsion spring, thereby driving the bottom plate 504 to rotate back and forth to disperse and screen the grain.

[0044] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
