Description

Technical Field

[0001] This utility model relates to the technical field of ship unloading equipment, and in particular to a telescopic enclosed dust removal and material guide chute for port ship unloading machines. Background Technology

[0002] The telescopic enclosed dust-collecting chute used in port ship unloaders is a key environmental protection device specifically designed for unloading bulk cargo (such as coal, ore, grain, fertilizer, etc.). Its core function is to facilitate the transfer of materials from the unloading port of the ship unloader (such as a grab bucket ship unloader) to the belt conveyor below.

[0003] The material transfer hub from the grab bucket to the belt conveyor faces serious dust pollution problems. When materials fall at high speed into the hopper, high concentrations of dust are generated due to airflow disturbance and impact effects. A large amount of inhalable particulate matter is released into the atmosphere without organization, which not only violates increasingly stringent environmental regulations but also endangers the health of workers and causes material loss. Currently, the industry generally uses fixed, enclosed guide chutes as a dust removal method. However, during ship unloading operations, ships are affected by tidal fluctuations and changes in cargo loading and unloading weight, resulting in continuous vertical lifting and horizontal drift. The ship unloader trolley also needs to move along the dock track. Fixed guide chutes cannot compensate for such multi-degree-of-freedom relative displacements, leading to an increase in the gap between the tail of the guide chute and the receiving area of ​​the conveyor belt below, inducing secondary dust. Therefore, this application provides a telescopic, enclosed dust removal guide chute for port ship unloaders to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a telescopic sealed dust removal guide chute for port ship unloaders to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A telescopic, enclosed dust removal and material guide chute for a port ship unloader includes: a hopper, a sealing groove fixedly installed at the bottom of the hopper, a material guide chute body fixedly installed at the bottom of the sealing groove, brackets fixedly installed on both side walls of the material guide chute body, an inclined plate fixedly installed at the corner of the inner cavity of the material guide chute body, an air pipe penetrating through the inner corner of the outer wall of the material guide chute body, a box fixedly installed at the end of the air pipe away from the material guide chute body, and a fan fixedly connected to the other side of the box.

[0007] The outer wall of the feed trough body is slidably connected to a sliding groove, and a dual-axis motor is fixedly installed at the bottom of the sliding groove. The output shaft of the dual-axis motor is fixedly connected to a rotating shaft, and a gear is fixedly installed at the front end of the rotating shaft. A toothed plate meshes with the outer edge of the gear.

[0008] The outer wall of the rotating shaft is rotatably connected to a support plate, and the other end of the support plate is fixedly connected to the bottom of the sliding groove.

[0009] Support legs are fixedly installed at the bottom of both ends of the toothed plate.

[0010] Rotating rods are fixedly installed on both sides of the sliding groove. Rollers are rotatably connected to the outer wall of the rotating rods, and sliding plates are slidably connected to the outer wall of the rollers. The inner cavity of the sliding plates is provided with a sliding groove.

[0011] The two ends of the sealing groove are connected to the hopper and the guide trough body through flanges, and the sealing groove itself is made of flexible rubber material.

[0012] A filter screen is fixedly installed inside the trachea, and a filter plate is fixedly installed inside the box, with the bottom of the filter plate not connected to the bottom of the box's inner cavity to form a communication.

[0013] Support columns are fixedly installed at the bottom of both ends of the skateboard.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. In the above scheme, when the material in the hopper enters the guide trough body through the sealing groove, it will fall onto the inclined plate to slow down and reduce dust. The dust generated when it falls onto the inclined plate will enter the box body through the air pipe. The dust in the air pipe will be filtered by the filter screen. Large particles that are blocked will return to the guide trough body, while smaller particles will be filtered by the filter plate when entering the box body and then fall into the box body for collection.

[0016] 2. In the above scheme, the rotating shaft is driven by a dual-shaft motor, which causes the gear to rotate and move on the gear plate. This causes the sliding chute to slide on the outer wall of the guide chute body, thereby adjusting the distance of the sliding chute to adapt to material conveying at different distances and improving its practicality.

Detailed Implementation

[0024] The following is a detailed description of a telescopic enclosed dust removal and material guide chute for a port ship unloader provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments; other alternative methods may be used by those skilled in the art. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a telescopic sealed dust removal guide chute for a port ship unloader, comprising: a hopper 1, a sealing groove 2 fixedly installed at the bottom of the hopper 1, a guide chute body 3 fixedly installed at the bottom of the sealing groove 2, brackets 4 fixedly installed on both sides of the guide chute body 3, an inclined plate 5 fixedly installed at the corner of the inner cavity of the guide chute body 3, an air pipe 6 penetrating through the inner corner of the outer wall of the guide chute body 3, a box 7 fixedly installed at one end of the air pipe 6 away from the guide chute body 3, and a fan 8 fixedly connected to the other side of the box 7. When the material in the hopper 1 enters the guide chute body 3 through the sealing groove 2, it will fall onto the inclined plate 5 for deceleration and dust reduction.

[0026] like Figure 1 and Figure 2As shown, a sliding groove 9 is slidably connected to the outer wall of the guide trough body 3. A dual-axis motor 10 is fixedly installed at the bottom of the sliding groove 9. A rotating shaft 11 is fixedly connected to the output shaft of the dual-axis motor 10. A gear 12 is fixedly installed at the front end of the rotating shaft 11. A toothed plate 13 meshes with the outer edge of the gear 12. The dual-axis motor 10 drives the rotating shaft 11 to rotate, causing the gear 12 to rotate accordingly. This causes the gear 12 to move on the toothed plate 13, thereby driving the sliding groove 9 to slide on the outer wall of the guide trough body 3. This allows the distance of the sliding groove 9 to be adjusted so that it can adapt to material conveying at different distances and improve its practicality.

[0027] like Figure 2 and Figure 3 As shown, a support plate is rotatably connected to the outer wall of the rotating shaft 11, and the other end of the support plate is fixedly connected to the bottom of the sliding groove 9.

[0028] like Figure 1 and Figure 2 As shown, support legs 14 are fixedly installed at the bottom of both ends of the toothed plate 13, and the toothed plate 13 is supported by the support legs 14.

[0029] like Figure 1 and Figure 3 As shown, rotating rods 17 are fixedly installed on both sides of the sliding groove 9. Rollers 18 are rotatably connected to the outer wall of the rotating rods 17. Slide plates 15 are slidably connected to the outer wall of the rollers 18. The inner cavity of the slide plates 15 is provided with a sliding groove 16.

[0030] like Figure 1 and Figure 2 As shown, the two ends of the sealing groove 2 are connected to the hopper 1 and the guide chute body 3 through flanges. The sealing groove 2 itself is made of flexible rubber material to ensure that it can effectively seal the discharge port under the movement of the unloader and the impact of the material, and prevent dust from escaping from the top.

[0031] like Figure 2 and Figure 3 As shown, a filter screen 61 is fixedly installed in the inner cavity of the air pipe 6, and a filter plate 71 is fixedly installed in the inner cavity of the box body 7. The bottom of the filter plate 71 is not connected to the bottom of the inner cavity of the box body 7 to form a communication. The dust in the air pipe 6 will be filtered by the filter screen 61. Large particles that are blocked will return to the feed chute body 3. Smaller particles will be filtered by the filter plate 71 when entering the box body 7, and then fall into the box body 7 for collection.

[0032] like Figure 1 and Figure 3 As shown, support columns are fixedly installed at the bottom of both ends of the skateboard 15.

[0033] The technical solution provided by this utility model allows for the following operation: When the material in the hopper 1 enters the guide trough body 3 through the sealing groove 2, it falls onto the inclined plate 5 for deceleration and dust reduction. The dust generated on the inclined plate 5 enters the box 7 through the air pipe 6. The dust in the air pipe 6 is filtered by the filter screen 61. Large particles that are blocked return to the guide trough body 3, while smaller particles are filtered by the filter plate 71 as they enter the box 7 and fall into the box 7 for collection. The dual-shaft motor 10 drives the rotating shaft 11 to rotate, causing the gear 12 to rotate as well. This causes the gear 12 to move on the toothed plate 13, thereby driving the sliding groove 9 to slide on the outer wall of the guide trough body 3. This allows for adjustment of the distance of the sliding groove 9, enabling it to adapt to material conveying at different distances and improving its practicality.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
