Description

Technical Field

[0001] This invention relates to the field of dust collection devices, and in particular to a dust collection device for coal conveying equipment. Background Technology

[0002] Coal conveying equipment is prone to operational problems and fire hazards due to material falling from the conveyor belts and dust accumulation. Therefore, regular dust removal is necessary. Currently, factories and mines use shovels to clean dust from various parts of the equipment. However, the narrow spaces at dust accumulation points in some parts of the coal conveying equipment present numerous inconveniences when using shovels. Shovels have a small cleaning capacity, requiring multiple manual cleanings, resulting in a small amount of dust removed per cleaning cycle and low personnel efficiency.

[0003] When using a square shovel to clean up accumulated dust, because the dust inside is spread out over a long distance, workers push the shovel forward and then pull it back to clean the dust inside. However, when pushing the shovel inward, the other side of the shovel tends to push the dust along the path even further away, resulting in less dust being carried out and a smaller amount being cleaned in a single operation. Therefore, multiple cycles are required to clean the dust inside, resulting in low cleaning efficiency for workers. Summary of the Invention

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a dust collection device for coal conveying equipment. In this embodiment, a moving part 201 is provided, which can open the front baffle 103a or the rear baffle 103b by different movement directions when the device is moving, so as to collect dust.

[0030] Specifically, the main body component 100 includes a housing 101, an accommodating cavity 102 disposed inside the housing 101, a dust-blocking member 103 disposed on the outer wall of the housing 101, and a protective shell 104 disposed at the end of the housing 101; and the pushing component 200 includes a moving member 201, a first pushing member 202 disposed on the inner wall of the protective shell 104, a fixing member 203 disposed at the end of the housing 101, a connecting member 204 disposed on the inner wall of the fixing member 203, and a second pushing member 205 disposed on the inner wall of the protective shell 104.

[0031] The dust baffles 103 are located on both sides of the housing 101. When the housing 101 moves back and forth, the different baffles on both sides will press down, thereby collecting the dust inside into the accommodating cavity 102 inside the housing 101. At the same time, the protective shell 104 at the bottom of the housing 101 has the function of blocking dust, preventing the leakage of dust from affecting the moving parts of the device.

[0032] Meanwhile, when the device moves, the moving part 201 will drive the first pushing part 202 and the second pushing part 205 to move. When moving inward, when the first pushing part 202 moves, it will drive the connecting part 204 inward, pulling the rear baffle 103b downward, collecting the dust along the way from the rear baffle 103b into the receiving cavity 102. When the device is pulled outward, the rear baffle 103b will rise and block the rear side of the housing 101. At this time, the front baffle 103a will be driven downward by the second pushing part 205, and the dust missed in the path will be collected into the receiving cavity 102.

[0033] In summary, during use, when the device moves inward, the movement of the moving part 201 drives the first pushing part 202 and the second pushing part 205 to move. At this time, the rear baffle 103b is pressed down, and the front baffle 103a is lifted up. During the movement, dust enters the receiving cavity 102 through the rear baffle 103b. Furthermore, dust will fall onto the road from the front during the forward movement. When pulled back, the rear baffle 103b will lift up to block the dust and prevent it from falling from the rear. At this time, the front baffle 103a will press down to collect the fallen dust and uncollected dust together from the front baffle 103a into the receiving cavity 102.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that when the dust blocking member 103 moves inward and outward, it will drop the front baffle 103a and the rear baffle 103b to collect the dust into the accommodating cavity 102.

[0036] Specifically, the outer wall of the housing 101 is provided with a first fixing block 101a and a second fixing block 101b. The inner wall of the second fixing block 101b is provided with a hinge shaft 101b-1. The end face of the housing 101 is provided with a first sliding groove 101c. The inner wall of the first sliding groove 101c is provided with a first limiting groove 101c-1. The end face of the housing 101 is provided with a second sliding groove 101c-2. The inner wall of the second sliding groove 101c-2 is provided with a second limiting groove 101c-3.

[0037] The first fixing block 101a and the second fixing block 101b are disposed on both sides of the housing 101, and the first sliding groove 101c and the second sliding groove 101c-2 are disposed on the bottom surface of the housing 101.

[0038] Preferably, the dust-blocking component 103 includes a front baffle 103a and a rear baffle 103b. The outer wall of the front baffle 103a is hinged to the first fixing block 101a. A first hinge block 103a-1 is provided at the end of the front baffle 103a. A connecting block 103b-1 is provided at the end of the rear baffle 103b. The end of the connecting block 103b-1 is sleeved on the outer wall of the hinge shaft 101b-1. A second hinge block 103b-2 is provided at the end of the rear baffle 103b. The end of the second hinge block 103b-2 is sleeved on the outer wall of the hinge shaft 101b-1.

[0039] The front baffle 103a is hinged to the side of the first fixing block 101a, while the rear baffle 103b is hinged to the connecting block 103b-1 on the surface, the second hinge block 103b-2, and the second fixing block 101b via the hinge shaft 101b-1 between them.

[0040] In summary, during use, when the device moves inward, the rear baffle 103b is hinged to the connecting block 103b-1, the second hinge block 103b-2, and the hinge shaft 101b-1, causing it to flip and touch the ground. At this time, dust is collected into the accommodating cavity 102 through the rear baffle 103b. When the device moves outward, the rear baffle 103b flips on the hinge shaft 101b-1. At this time, the rear baffle 103b blocks the rear side of the housing 101, preventing dust from falling from the rear side. At the same time, the front baffle 103a flips downward, collecting the dust on the path from the front baffle 103a into the accommodating cavity 102. Because the rear side is blocked by the flipped rear baffle 103b, a large amount of dust will not fall.

[0041] Example 3

[0042] Reference Figures 3-6 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that when the moving part 201 moves, when the device moves inward, it urges the first pushing part 202 to drive the connecting part 204 to move, so that the rear baffle 103b flips downward to collect dust. At this time, the second pushing part 205 drives the front baffle 103a to lift upward and not contact the ground.

[0043] Specifically, the moving component 201 includes a roller 201a, a rotating shaft 201a-1 is provided at the center of the roller 201a, a flywheel inner shaft 201b is sleeved on the outer wall of the rotating shaft 201a-1, a protrusion 201b-1 is arranged in an array on the outer wall of the flywheel inner shaft 201b, a locking rod 201b-2 is provided on the outer wall of the protrusion 201b-1, a first elastic element 201b-3 is provided on the end face of the locking rod 201b-2, the other end of the first elastic element 201b-3 is connected to the flywheel inner shaft 201b, a flywheel 201c is also provided on the outer wall of the flywheel inner shaft 201b, a push block 201c-1 is provided on the inner wall of the flywheel 201c, the moving component 201 also includes a first fixed plate 201d, a first output gear 201d-1 is provided at the end of the first fixed plate 201d, and the first output gear 201d-1 meshes with the flywheel 201c.

[0044] The inner shaft 201b of the flywheel is sleeved on the outer wall of the rotating shaft 201a-1. The inner shaft 201b of the flywheel rotates with the rotating shaft 201a-1. When the device moves backward, the locking rod 201b-2 on the outer wall of the inner shaft 201b of the flywheel contacts the flat surface of the push block 201c-1. At this time, the inner shaft 201b of the flywheel cannot drive the flywheel 201c to rotate. When the device moves forward, the locking rod 201b-2 on the outer wall of the inner shaft 201b of the flywheel contacts the protruding surface of the push block 201c-1. At this time, the flywheel 201c is driven to rotate, and the flywheel 201c meshes with the first output gear 201d-1. At this time, the rotation of the flywheel 201c drives the first output gear 201d-1 to rotate.

[0045] Preferably, the first pushing member 202 includes a first rack 202a, which meshes with a first output gear 201d-1. A first sliding plate 202a-1 is provided at the end of the first rack 202a, which extends into and slides into the first sliding groove 101c. The outer wall of the first sliding plate 202a-1 extends into and slides into the first limiting groove 101c-1. A second elastic member 202a-2 is provided on the outer wall of the first rack 202a. A spring block 202a-3 is provided at the other end of the second elastic member 202a-2. A slider 202a-4 is provided at the end of the spring block 202a-3, and the end of the slider 202a-4 extends into and slides into the first limiting groove 101c-1.

[0046] In this configuration, the first rack 202a slides within the first groove 101c, and the first slide plate 202a-1 slides within the first limiting groove 101c-1. Simultaneously, the rebound block 202a-3 is connected to the first rack 202a via the second elastic element 202a-2. When the device moves inward, the flywheel 201c does not rotate, and the first output gear 201d-1 also does not rotate. At this time, the first rack 202a is located on the inner side of the first groove 101c. When the device moves outward, the flywheel 202a... When 01c rotates, it drives the first output gear 201d-1 to rotate. At this time, the first rack 202a is driven by the first output gear 201d-1 to move towards the rear baffle 103b, flipping the rear baffle 103b up. Then the first output gear 201d-1 continues to rotate and contacts the spring block 202a-3. The spring block 202a-3 is affected by the second elastic element 202a-2 and keeps in contact with the first output gear 201d-1, maintaining the rearward position of the first rack 202a.

[0047] The fastener 203 includes a fixing frame 203a, a fixing groove 203a-1 is provided through the end face of the fixing frame 203a, a connecting frame 203b is provided on the outer wall of the fixing frame 203a, and a hinge rod 203c is provided at the end of the connecting frame 203b.

[0048] The fixing frame 203a is fixed to the bottom of the housing 101, and fixing grooves 203a-1 are provided on both sides of the fixing frame 203a.

[0049] The connector 204 includes a connecting rod 204a, one end of which is hinged to a first rack 202a. The other end of the connecting rod 204a is hinged to a push rod 204b. A limit block 204b-1 is provided at the end of the push rod 204b. The end of the limit block 204b-1 extends into the fixing groove 203a-1 and slides therewith. A curved rod 204c is hinged to the end of the push rod 204b. A guide groove 204c-1 is provided through the outer wall of the curved rod 204c. The hinge rod 203c slides therewith with the guide groove 204c-1. The other end of the curved rod 204c is hinged to the outer wall of the second hinge block 103b-2.

[0050] One end of the connecting rod 204a is hinged to the first rack 202a, and the other end is hinged to the push rod 204b. When the first rack 202a moves, it drives the connecting rod 204a to move. The connecting rod 204a drives the push rod 204b to move toward the rear of the housing 101. The push rod 204b is inside the fixed frame 203a. The limiting blocks 204b-1 on both sides of the push rod 204b slide in the fixing groove 203a-1 opened on the outer wall of the fixed frame 203a. At the same time, the push rod 204b drives the curved rod 204c to move. The guide groove 204c-1 opened on the outer wall of the curved rod 204c is located in the guide groove 204c-1. The hinge rod 203c at the end of the connecting frame 203b is set in the guide groove 204c-1. By driving the movement of the curved rod 204c, the rear baffle 103b is driven to flip upward and block the rear of the housing 101.

[0051] The second pusher 205 includes a sleeve 205a, an installation groove 205a-1 is provided on the outer wall of the sleeve 205a, a moving block 205b is provided in the installation groove 205a-1, a third elastic element 205b-1 is provided at the end of the moving block 205b, an external gear 205c is sleeved on the outer wall of the sleeve 205a, and a groove 205c-1 is provided on the inner wall of the external gear 205c.

[0052] The sleeve 205a is fitted onto the outer wall of the rotating shaft 201a-1. The mounting groove 205a-1 on the outer wall of the sleeve 205a is fitted with a moving block 205b and a third elastic element 205b-1. Meanwhile, the inner wall of the external gear 205c on the outer wall of the sleeve 205a is provided with a groove 205c-1. The end of the moving block 205b is in the groove 205c-1. The sleeve 205a drives the external gear 205c to rotate as the rotating shaft 201a-1 rotates.

[0053] The second pusher 205 includes a second output gear 205d, which meshes with an external gear 205c. A second fixing plate 205d-1 is provided on the outer wall of the second output gear 205d. The second pusher 205 also includes a second rack 205e, which meshes with the second output gear 205d. A second sliding plate 205e-1 is provided on the outer wall of the second rack 205e. The end of the second rack 205e extends into the second sliding groove 101c-2 and slides therewith. The outer wall of the second sliding plate 205e-1 extends into the second limiting groove 101c-3 and slides therewith.

[0054] The second output gear 205d meshes with the external gear 205c. The second output gear 205d is fixed to the bottom of the housing 101 by the second fixing plate 205d-1. The second rack 205e slides in the second limiting groove 101c-3 by the second sliding plate 205e-1, thereby sliding in the second sliding groove 101c-2.

[0055] Furthermore, when the second rack 205e reaches its end and can no longer slide, the second output gear 205d also stops rotating. Correspondingly, the external gear 205c also cannot rotate at this time. However, the device continues to move, so the rotating shaft 201a-1 drives the sleeve 205a to rotate together. At this time, the external gear 205c stops rotating. When the inner sleeve 205a continues to rotate, the arc surface of the groove 205d-1 contacts and presses the end face of the moving block 205b, thus pressing the moving block 205b inward and pressing the third elastic element 205b-1, thus pressing the moving block 205b into the mounting groove 205a-1 on the outer wall of the sleeve 205a. At this time, the sleeve 205a continues to rotate with the rotating shaft 201a-1, and the external gear 205c stops rotating.

[0056] Preferably, the end face of the second rack 205e is provided with a hinge post 205e-2, and a support rod 205f is hinged to the outer wall of the hinge post 205e-2. The outer wall of the support rod 205f is provided with a movable groove 205f-1. The other end of the support rod 205f is hinged to the outer wall of the first hinge block 103a-1. The second pusher 205 also includes a third fixing block 205g. The inner wall of the third fixing block 205g is provided with a limit rod 205g-1, and the limit rod 205g-1 slides in cooperation with the movable groove 205f-1.

[0057] Among them, the limiting rod 205g-1 on the inner wall of the third fixing block 205g slides in the movable groove 205f-1 opened on the end face of the support rod 205f. One end of the support rod 205f is hinged to the hinge post 205e-2 on the end face of the second rack 205e, and the other end is hinged to the first hinge block 103a-1 on the end face of the front baffle 103a. Through the single movement of the second rack 205e, the support rod 205f is driven to move, thereby driving the front baffle 103a to press down or lift up.

[0058] In summary, during use, when the device moves inward, the inner shaft 201b of the flywheel rotates within the flywheel 201c along with the rotating shaft 201a-1, but does not drive the flywheel 201c to rotate. At this time, the first pushing member 202 does not move, and the rear baffle 103b is not affected by external forces. At this time, the other end of the rear baffle 103b contacts the ground, collecting dust from the rear baffle 103b into the receiving cavity 102. Simultaneously, the second pushing member 205, along with the movement of the moving member 201, drives the second rack 205e to move, pushing the support rod 205f outward. This causes the front baffle 103a to lift upwards and not contact the ground. When the device moves outwards, the inner shaft 201b of the flywheel drives the flywheel 201c to rotate, thereby driving the first rack 202a to move. At this time, the rear baffle 103b is flipped by force, blocking the rear side of the housing 101 and collecting the dust into the accommodating cavity 102. At the same time, the second rack 205e is driven by the second output gear 205d to move backwards, bringing the support rod 205f inwards. At this time, the front baffle 103a will move downwards, collecting the dust in the path into the accommodating cavity.
