[0002] In tobacco production, vibrating conveyors are often used to transport tobacco leaves and remove fine tobacco by vibration. However, in actual operations, a large amount of dust is mixed in the tobacco sheets. When the vibration trough vibrates, the dust will spread around with the airflow, causing the dust content in the air on site to seriously exceed the standard. In addition, there is a large amount of dust accumulation on the surface of the equipment, which has a great impact on the health of the operators.
[0003] In the prior art, a cover is directly added to the vibration trough to reduce dust overflow. However, the cover is directly fixed to the vibration trough, and the cover vibrates synchronously with the vibration trough, which directly increases the load of the power unit, reduces the amount of goods that can be accommodated in the vibration trough at one time, and reduces the overall efficiency.
[0004] In summary, how to provide a dust cover that can reduce dust diffusion during the production process without affecting the conveying efficiency of the vibrating conveying equipment is a problem that urgently needs to be solved by technical personnel in this field. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] The core of the utility model is to provide a dustproof cover, which adopts a cover body separated from the vibration groove, reduces the load of the power unit, improves the transmission efficiency, and adopts a dustproof soft connection to seal the cover body and the vibration groove, further improves the sealing performance, reduces dust overflow, and improves the on-site environment.
[0034] Another core of the utility model is to provide a vibrating conveying device including the above-mentioned dust cover, which has the same technical features and can achieve the same purpose.
[0035] Please refer to Figure 1-Figure 3 , a dust cover, used for sealing and dustproofing the vibration groove 8 in the vibration conveyor, comprising:
[0036] The cover body 1 is provided with a penetrating vibration trough feed port 5 at one end close to the vibration trough 8 feed end;
[0037] The support base 2 is used to fix the cover body 1 to the frame 7 of the vibrating conveyor;
[0038] The dustproof flexible connection 4 is arranged in a ring shape and is used to cover the gap between the sealing cover 1 and the vibration groove 8, and is fixedly connected to the cover 1 and the vibration groove 8 at the same time;
[0039] The outlet dust curtain 3 is arranged at the discharge end of the vibration groove 8 , and the upper edge is fixedly connected to the cover body 1 .
[0040] In actual use, the vibrating conveyor includes a vibration trough 8, a frame 7, a vibration trough main beam fixed to the frame 7, a rocker, and a driving main beam. The two ends of the rocker are respectively hinged to the vibration trough 8 and the driving main beam, and a slider is slidably arranged inside the rocker, and the slider is hinged to the vibration trough main beam. When working, the driving main beam reciprocates in the horizontal plane, driving the vibration trough 8 to do up and down bumps and reciprocating movements back and forth.
[0041] Therefore, the support seat 2 is used to fix the cover body 1 and the frame 7 or the main beam of the vibration trough. The cover body 1 is not directly connected to the vibration trough 8. When the vibration trough 8 moves, the cover body 1 does not move synchronously with the vibration trough 8, thereby reducing the mass of the vibration trough 8 and the load of the power unit, thereby increasing the maximum load in the vibration trough 8 and improving the conveying efficiency.
[0042] Moreover, the support base 2 is used to fix the cover body 1, and there is no need to make too many changes to the structure of the vibration groove 8 and the frame 7 itself. It only needs to be installed on the outside. The difficulty of modification is relatively low, and the impact on the operation effect of the equipment is small. There is no need to match the power unit of the equipment, that is, debugging is relatively simple.
[0043] At the same time, a dustproof soft connection 4 is used to seal the gap between the cover body 1 and the vibration groove 8, wherein the dustproof soft connection 4 is preferably made of flexible sealing materials such as thick canvas, dustproof cloth, or thin rubber pad, and when the dustproof soft connection 4 is connected to the cover body 1 and the vibration groove 8, it is in a relaxed state, and will not affect the relative movement of the cover body 1 and the vibration groove 8, and can effectively prevent dust from overflowing from the gap between the two, thereby achieving the expected effect.
[0044] At the same time, a vibration trough feed port 5 is provided on the cover body 1, and raw materials can be added through the vibration trough feed port 5 without affecting the normal operation of the vibrating conveyor. At the same time, an outlet dust curtain 3 is provided at the discharge end of the vibration trough 8. The outlet dust curtain 3 is installed in a manner of fixing the upper edge and freeing the lower edge. When the material in the vibration trough 8 is discharged, the material can push open the outlet dust curtain 3 from the inside, thereby not affecting the discharge of the vibration trough 8. After the discharge is completed, the outlet dust curtain 3 can automatically reset under the action of gravity, thereby realizing the re-sealing of the discharge end of the vibration trough 8, reducing dust overflow, and improving the work site environment.
[0045] In some embodiments, the cover body 1 includes a frame body 101, the surface of the frame body 101 is covered with a plurality of sets of cover plates 102, and the vibration slot feed port 5 passes through the cover plates 102;
[0046] The cover body 1 adopts a frame-type structural design, which reduces the overall mass and is easy to install. It also adopts a plurality of sets of cover plates 102 for partitioned coverage. In some embodiments, the cover plate 102 is fixedly connected to the frame body 101. The connection methods include but are not limited to bolt connection, welding, riveting, etc. The cover plate 102 and the frame body 101 have good connection stability. Since the frame body 101 and the cover plate 102 are relatively fixed connections, the joints can be sealed by adding welds or filling sealants to ensure the sealing performance and effectively prevent internal dust from overflowing.
[0047] In other embodiments, the cover plate 102 also adopts a partition covering method, but the cover plate 102 adopts a detachable design, such as Figure 2 As shown, a first sealing ring 103 is provided between the inner wall of the cover plate 102 and the contact surface of the frame body 101, and a clamping assembly 104 is provided outside the frame body 101 for applying force to the surface of the cover plate 102 to make it fit the frame body 101;
[0048] By setting a first sealing ring 103 at the contact position between the cover plate 102 and the frame body 101, and adding a clamping component 104, a clamping force is applied to the cover plate 102, so that the cover plate 102 is tightly attached to the frame body 101, and the first sealing ring 103 is pressed to undergo elastic deformation, so as to increase the sealing performance at the joint and reduce internal dust overflow. Among them, the clamping component 104 can be a snap-on structure or a clamping pliers structure design to facilitate the release of the clamping force. After release, the cover plate 102 can be easily removed, and the frame body 101 does not need to be disassembled, and the vibration groove 8 can be entered for maintenance. Moreover, since the cover plate 102 is partitioned, it can be disassembled and maintained in partitions, which further improves the convenience of maintenance and reduces maintenance costs.
[0049] In other embodiments, in order to further improve the sealing between the cover plate 102 and the frame body 101, as shown in FIG. Figure 3 As shown, the edge of the cover plate 102 is provided with a downward bend, and a second sealing ring 107 is provided between the bent edge and the frame body 101;
[0050] When the cover 102 is pressed downward, the inner wall of the cover 102 presses the first sealing ring 103, and the bent edge of the cover 102 presses the second sealing ring 107, thereby achieving double sealing between the cover 102 and the frame body 101, thereby improving its sealing performance and further reducing the amount of internal dust overflow.
[0051] In some embodiments, the dustproof flexible connection 4 is fixed to the cover body 1 and / or the vibration groove 8 by gluing or binding. Although the gluing connection has good sealing performance, most of the gluing will debond under high temperature, and the edge of the gluing area will gradually infiltrate dust. With the continuous infiltration of dust, the gluing area will gradually decrease until the dustproof flexible connection 4 is completely detached, so it has a certain instability.
[0052] However, when the binding tape is used for fixing, there will be a large gap between the dustproof flexible connection 4 and the cover body 1 or the vibration groove 8, and a large amount of dust will still overflow from the gap, which will not achieve the desired effect;
[0053] Therefore, in some embodiments, the upper edge of the dustproof flexible connection 4 overlaps and is fixedly connected to the inner wall portion of the frame body 101, and the lower edge overlaps and is fixedly connected to the inner wall portion of the vibration groove 8;
[0054] The inner wall of the frame body 101 is fixedly connected with a first fixing strip 105 by bolts, and the dustproof flexible connector 4 is clamped between the first fixing strip 105 and the inner wall of the frame body 101 .
[0055] The inner wall of the vibration groove 8 is fixedly connected with a second fixing strip 106 by bolts, and the lower edge of the dustproof flexible connection 4 is clamped between the second fixing strip 106 and the inner wall of the vibration groove 8;
[0056] That is, by partially overlapping the dustproof flexible connection 4 and its fixed position, and the overlapping part is compressed by the first fixing strip 105 and the second fixing strip 106, and the first fixing strip 105 and the second fixing strip 106 are both fixed to the cover body 1 or the vibration groove 8 at the corresponding position by bolts, and then the force of the first fixing strip 105 and the second fixing strip 106 is dispersed, so that the entire edge connection position of the dustproof flexible connection 4 is in a clamping and sealing connection state, which effectively reduces the gap between the dustproof flexible connection 4 and the cover body 1 and the vibration groove 8, and further reduces the probability of dust overflow;
[0057] At the same time, the first fixing bar 105 and the second fixing bar 106 are both fixed by bolts, which has the advantage of being easy to disassemble and repair compared to connection methods such as welding.
[0058] In some embodiments, a transparent observation window 6 is provided on the surface of the cover body 1;
[0059] For the one-piece cover body 1, it is necessary to open a hole on the surface of the cover body 1 and install a transparent observation window 6. For the design of a combination of a frame body 101 of a frame-type structure and a partition-covering cover plate 102, a single cover plate 102 can be replaced with a transparent observation window 6. The above two methods are within the protection scope of this application and are protected by this application.
[0060] In addition to the dust cover disclosed in the above embodiments, the present invention also provides a vibrating conveying device including the above dust cover. For the structures of other parts of the vibrating conveying device, please refer to the prior art and will not be described in detail herein.
[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0062] The dust cover and the vibrating conveying device provided by the utility model are introduced in detail above. The principle and implementation method of the utility model are explained in this article using specific examples. The description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
