Description

Technical Field

[0001] The utility model relates to a conveyor belt dust suction device, belonging to the technical field of transmission equipment. Background Art

[0002] Conveyor belt, also known as conveyor belt, is a mechanical transmission device used in belt conveyor, mainly used to carry and transport materials. Conveyor belt is widely used in the transportation of cement, sand, gravel, etc.

[0003] In the prior art, due to the large amount of dust attached to the surface of sand and gravel, a large amount of dust is often raised during the conveyor belt transportation of sand and gravel, which harms the health of workers and pollutes the workshop environment. Therefore, at present, workers often set up a dust hood above the conveyor belt, and a dust suction fan is set inside the dust hood. During the conveyor belt transportation of sand and gravel, the dust suction fan is started to absorb the dust raised on the surface of the conveyor belt.

[0004] However, since the existing dust hood is usually installed by fixing it above the conveyor belt through a number of bolts, during the actual installation, the staff is required to lift the dust hood by a crane in advance and place it directly above the conveyor belt, and then manually align the bolt holes at the four corners of the dust hood with the bolt holes at the four corners of the conveyor belt, and then screw a number of bolts into the bolt holes of the dust hood and the conveyor belt in turn to complete the installation of the dust hood. The operation is extremely inconvenient, time-consuming and labor-intensive. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a conveyor belt dust suction device, which solves the problem in the prior art that the existing dust hood is usually installed in a manner of fixing it above the conveyor belt by a plurality of bolts. During the specific installation, the staff needs to lift the dust hood by a crane in advance and place it just above the conveyor belt, and then manually align the bolt holes at the four corners of the dust hood with the bolt holes at the four corners of the conveyor belt, and then screw a plurality of bolts into the bolt holes of the dust hood and the conveyor belt in turn to complete the installation of the dust hood, which is extremely inconvenient, time-consuming and laborious.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a conveyor belt dust suction device, comprising a conveyor belt and a dust hood, the conveyor belt comprising a conveyor belt and a conveyor frame, railings are fixed to the top of both sides of the conveyor frame along the length direction, the railings are composed of a plurality of vertically arranged rod bodies and a plurality of rod bodies are integrally formed with sliders on the top, slide rails for the sliders to be clamped are arranged at the bottom of both sides of the dust hood, a protrusion is fixed at one end of the slider, pressure blocks are arranged on both sides of one end of the dust hood, a groove for the protrusion to be clamped is provided on the end of the pressure block facing the slider, and a connector for detachably connecting to the railing is arranged at the end of the dust hood away from the pressure block.

[0007] By adopting the above technical solution, in the actual process of transporting sand and gravel through the conveyor belt, the dust hood is first lifted by a crane, and then the slide rail of the dust hood away from the pressing block is aligned with the slider and snapped in, and then the dust hood is pushed, and the dust hood can be easily slid along the slider until the protrusion is snapped into the groove, and finally the end of the dust hood away from the pressing block is connected to the railing through a connecting piece, and the dust hood can be easily installed and fixed on the conveyor belt, which is easy to operate and saves time and effort.

[0008] Among them, the setting of the protrusion and the pressure block plays a role in positioning the dust hood. Through the positioning of the pressure block by the protrusion, the connecting piece can be connected to the railing more accurately.

[0009] The utility model is further configured as follows: the connecting piece includes two connecting plates, the tops of the two connecting plates are connected by a connecting block, a plate groove is provided on the inner wall of the dust hood, the two connecting plates are respectively slidably connected to both sides of the plate groove along the vertical direction, a connecting groove for the connecting plate to be snapped into is provided on the top of one end of the slider away from the protrusion, the connecting groove extends into the interior of the rod body, and a locking piece for detachably connecting to the connecting block is provided on the dust hood.

[0010] By adopting the above technical solution, after the protrusion is inserted into the groove, the connecting plate is just aligned with the connecting groove. At this time, it is only necessary to release the connection between the locking piece and the connecting block, and the connecting block can slide down along the plate groove, while driving the connecting plate to be inserted into the connecting groove. The connecting groove limits the connecting plate, so that the dust hood can be stably installed on the railing, and the operation is convenient.

[0011] Among them, since the tops of the two connecting plates are connected by a connecting block, the two connecting plates can be driven to move downward together by pressing down the connecting block, which is easy to operate.

[0012] The utility model is further configured as follows: the locking piece is a bayonet which is rotatably connected to the top of the dust hood and one end of the bayonet extends into the interior of the dust hood; a through hole for the bayonet to be inserted into is provided on the top of the connecting plate; a locking block is provided on the outer peripheral wall of the bayonet; and a locking groove for the locking block to be inserted is axially penetrated on the inner peripheral wall of the through hole.

[0013] By adopting the above technical solution, when it is necessary to release the connection between the locking piece and the connecting block, it is only necessary to rotate the latch pin so that the locking block rotates to the bottom of the locking groove and aligns it. Since the locking block no longer abuts the connecting block at this time, the connecting block can fall under the action of gravity, so that the connecting plate can be stuck into the connecting groove.

[0014] When it is necessary to connect the connecting block with the pin, it is only necessary to lift the connecting block upwards so that the pin and the locking block are inserted into the through hole and the locking groove until the locking block completely passes through the locking groove, and then rotate the pin so that the locking block can abut against the bottom surface of the connecting block. The locking block limits the connecting block so that the connecting block will not fall under the action of gravity, and the connection operation is convenient.

[0015] The utility model is further configured as follows: a fixing block is provided on one side of the railing, a clamping hole is opened in the interior of the fixing block along the horizontal direction, a pressure rod is slidably connected in the clamping hole, one end of the pressure rod extends into the interior of the connecting groove, a slot for the pressure rod to be clamped is opened on the side of the connecting plate facing the conveyor belt, a pressure plate is provided on the outer peripheral wall of the pressure rod, an annular groove for the sliding of the pressure plate is opened axially on the inner peripheral wall of the clamping hole, an elastic member is also sleeved on the pressure rod, one end of the elastic member is fixed to one side of the pressure plate, and the other end is fixed to the inner wall of the annular groove on the side away from the connecting groove, an inclined surface is provided at the bottom end of the connecting plate, and a guiding inclined surface matching the inclined surface is provided at one end of the pressure rod.

[0016] By adopting the above technical solution, during the process of the connecting plate being inserted into the connecting groove, the inclined surface will fit with the guiding inclined surface, and then the staff will press the connecting block downward, so that the connecting plate will be pressed down accordingly. Under the guiding action of the inclined surface and the guiding inclined surface, the pressure rod will be forced to retreat until it completely enters the clamping hole, and the connecting plate will continue to move downward. During the process of the pressure rod being forced to retreat, the pressure plate will squeeze the elastic member so that the elastic member generates elastic force. When the connecting plate moves down to the bottom of the connecting groove, the slot is just aligned with the clamping hole. At this time, since the connecting plate no longer abuts the pressure rod, the elastic member returns to its original state and drives the pressure rod to be clamped into the slot. The connection plate is limited by the pressure rod, so that the connection plate cannot be separated from the connection groove, thereby making the connection between the connecting plate and the railing more stable and the connection operation more convenient.

[0017] When the connecting plate needs to be removed, the two pressing rods only need to be pulled in a direction away from the connecting plate to easily release the position restriction of the pressing rods on the connecting plate, thereby easily lifting the connecting plate.

[0018] The utility model is further configured as follows: a plurality of embedding grooves are provided on the top surface of the slider at equal intervals along the length direction, rollers are rotatably connected in the embedding grooves, and the top ends of the rollers protrude from the surface of the slider to abut against the inner top wall of the slide rail.

[0019] By adopting the above technical solution, the setting of the roller enables the sliding friction between the slide rail and the slider to be converted into rolling friction through the roller when the slide rail slides on the slider, thereby reducing the friction between the slider and the slide rail, thereby making the dust hood slide more smoothly.

[0020] The utility model is further configured that a hair dryer is arranged inside the dust cover.

[0021] By adopting the above technical solution, the dust on the surface of the sand and stone can be blown up by the hair dryer, so that the vacuum cleaner can suck more cleanly.

[0022] The utility model is further configured as follows: baffles for shielding the railings are arranged on both sides of the inner wall of the dust collection hood

[0023] By adopting the above technical solution, on the one hand, the transported sand and gravel are not easy to slip from the gap of the rod body, and on the other hand, it can prevent the flying dust in the dust hood from escaping from the dust hood.

[0024] The beneficial effect of the utility model is that in the actual process of transporting sand and gravel by the conveyor belt, the dust hood is first lifted by a crane, and then the slide rail of the end of the dust hood away from the pressing block is aligned with the slider and snapped in, and then the dust hood is pushed, and the dust hood can be easily slid along the slider until the protrusion is snapped into the groove, and finally the end of the dust hood away from the pressing block is connected to the railing through a connecting piece, so that the dust hood can be easily installed and fixed on the conveyor belt, which is easy to operate and saves time and effort.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0031] like Figure 1 and Figure 2As shown, a conveyor belt dust suction device comprises a conveyor belt 2 and a dust hood 1, the conveyor belt 2 comprises a conveyor belt 30 and a conveyor frame 31, railings 3 are fixed to the top of both sides of the conveyor frame 31 along the length direction, the railings 3 are composed of a plurality of vertically arranged rod bodies 29 and a plurality of rod bodies 29 are integrally formed with sliders 14 on the tops, both sides of the dust hood 1 are provided with slide rails 16 for the sliders 14 to be clamped, a protrusion 5 is fixed to one end of the slider 14, pressure blocks 4 are provided on both sides of one end of the dust hood 1, and a groove for the protrusion 5 to be clamped is provided on the end of the pressure block 4 facing the slider 14, and a connector for detachably connecting to the railing 3 is provided on the end of the dust hood 1 away from the pressure block 4.

[0032] In the actual process of transporting sand and gravel through the conveyor belt 2, the dust hood 1 is first lifted by a crane, and then the slide rail 16 at the end of the dust hood 1 away from the pressing block 4 is aligned with the slider 14 and snapped in, and then the dust hood 1 is pushed, and the dust hood 1 can be easily slid along the slider 14 until the protrusion 5 is snapped into the groove, and finally the end of the dust hood 1 away from the pressing block 4 is connected to the railing 3 through a connecting piece, and the dust hood 1 can be easily installed and fixed on the conveyor belt 2, which is easy to operate and saves time and effort.

[0033] The arrangement of the protrusion 5 and the pressing block 4 plays a role in positioning the dust hood 1. By positioning the pressing block 4 by the protrusion 5, the connecting piece can be connected to the railing 3 more accurately.

[0034] like Figure 4 and Figure 1 As shown, the connecting member includes two connecting plates 8, and the tops of the two connecting plates 8 are connected by a connecting block 25. A plate groove 18 is provided on the inner wall of the dust hood 1, and the two connecting plates 8 are respectively slidably connected to the two sides of the plate groove 18 along the vertical direction. A connecting groove 9 for the connecting plate 8 to be inserted is provided on the top of the end of the slider 14 away from the protrusion 5, and the connecting groove 9 extends into the interior of the rod body 29. A locking member for detachably connecting with the connecting block 25 is provided on the dust hood 1.

[0035] After the protrusion 5 is inserted into the groove, the connecting plate 8 is just aligned with the connecting groove 9. At this time, you only need to release the connection between the locking piece and the connecting block 25, and the connecting block 25 can slide down along the plate groove 18, while driving the connecting plate 8 to be inserted into the connecting groove 9. The connecting groove 9 limits the connecting plate 8, so that the dust hood 1 can be stably installed on the railing 3, and the operation is convenient.

[0036] Among them, since the tops of the two connecting plates 8 are connected by the connecting block 25, the two connecting plates 8 can be driven to move downward together by pressing down the connecting block 25, which is easy to operate.

[0037] like Figure 4 and Figure 1As shown, the locking member is a bayonet 12 rotatably connected to the top of the dust hood 1 and one end of the bayonet 12 extends into the interior of the dust hood 1. A through hole 28 for the bayonet 12 to be inserted is provided on the top of the connecting plate 8. A locking block 24 is provided on the outer peripheral wall of the bayonet 12. A locking groove 27 for the locking block 24 to be inserted is axially penetrated on the inner peripheral wall of the through hole 28.

[0038] When it is necessary to release the connection between the locking member and the connecting block 25, it is only necessary to rotate the latch 12 so that the locking block 24 rotates to the bottom of the locking groove 27 and aligns with it. At this time, the locking block 24 no longer abuts against the connecting block 25, so that the connecting block 25 can fall under the action of gravity, so that the connecting plate 8 can be inserted into the connecting groove 9.

[0039] When it is necessary to connect the connecting block 25 with the bayonet 12, it is only necessary to lift the connecting block 25 upwards so that the bayonet 12 and the locking block 24 are inserted into the through hole 28 and the locking groove 27 until the locking block 24 completely passes through the locking groove 27, and then rotate the bayonet 12 so that the locking block 24 can abut against the bottom surface of the connecting block 25. The locking block 24 limits the connecting block 25 so that the connecting block 25 will not fall under the action of gravity, and the connection operation is convenient.

[0040] like Figure 2 and Figure 3 and Figure 4 As shown, a fixing block 10 is provided on one side of the railing 3, and a clamping hole 32 is opened in the interior of the fixing block 10 along the horizontal direction. A pressure rod 11 is slidably connected in the clamping hole 32, and one end of the pressure rod 11 extends into the interior of the connecting groove 9. A slot 26 for the pressure rod 11 to be clamped is opened on the side of the connecting plate 8 facing the conveyor belt 2, and a pressure plate 22 is provided on the outer peripheral wall of the pressure rod 11. An annular groove 21 for the sliding of the pressure plate 22 is opened axially on the inner peripheral wall of the clamping hole 32. An elastic member 20 is also sleeved on the pressure rod 11, and one end of the elastic member 20 is fixed to one side of the pressure plate 22, and the other end is fixed to the inner wall of the annular groove 21 away from the connecting groove 9. An inclined surface 15 is provided at the bottom end of the connecting plate 8, and a guiding inclined surface 19 matching the inclined surface 15 is provided at one end of the pressure rod 11.

[0041] When the connecting plate 8 is inserted into the connecting groove 9, the inclined surface 15 will fit with the guiding inclined surface 19, and then the staff will press the connecting block 25 downward, so that the connecting plate 8 is pressed down accordingly. Under the guiding action of the inclined surface 15 and the guiding inclined surface 19, the pressure rod 11 will be forced to retreat until it completely enters the clamping hole 32, and the connecting plate 8 will continue to move downward. During the process of the pressure rod 11 being forced to retreat, the pressure plate 22 will squeeze the elastic member 20 accordingly, so that the elastic member 20 generates elastic force. When the connecting plate 8 moves down to the bottom of the connecting groove 9, the slot 26 is just aligned with the clamping hole 32. At this time, since the connecting plate 8 no longer abuts the pressure rod 11, the elastic member 20 returns to its original state and drives the pressure rod 11 to be clamped into the slot 26. The pressure rod 11 limits the connecting plate 8, so that the connecting plate 8 cannot be separated from the connecting groove 9, thereby making the connection between the connecting plate 8 and the railing 3 more stable and the connection operation more convenient.

[0042] When the connecting plate 8 needs to be removed, the two pressing rods 11 only need to be pulled in a direction away from the connecting plate 8 to easily release the position restriction of the pressing rods 11 on the connecting plate 8, thereby easily lifting the connecting plate 8.

[0043] like Figure 1 and Figure 2 As shown, a plurality of embedding grooves 23 are formed on the top surface of the slider 14 at equal intervals along the length direction, and a roller 17 is rotatably connected in the embedding groove 23 . The top end of the roller 17 protrudes from the surface of the slider 14 to abut against the inner top wall of the slide rail 16 .

[0044] The setting of the roller 17 allows the sliding friction between the slide rail 16 and the slider 14 to be converted into rolling friction through the roller 17 when the slide rail 16 slides on the slider 14, thereby reducing the friction between the slider 14 and the slide rail 16, thereby making the dust hood 1 slide more smoothly.

[0045] like Figure 1 As shown, a blower 6 is arranged inside the dust hood 1, and the dust on the surface of the sand and stone is blown up by the blower 6, so that the vacuum cleaner 7 can suck more cleanly.

[0046] like Figure 1 As shown, baffles 13 for shielding the railings 3 are provided on both sides of the inner wall of the dust hood 1, specifically, for shielding the gaps between a plurality of rod bodies 29. Through the shielding effect of the baffles 13, on the one hand, the transported sand and gravel are not easy to slide through the gaps of the rod bodies 29, and on the other hand, the flying dust in the dust hood 1 can be prevented from escaping from the dust hood 1.

[0047] Working principle:

[0048] When sand and gravel are actually transported by the conveyor belt 2 and the dust collection device is installed, the dust hood 1 is first lifted by a crane, and then the slide rail 16 at the end of the dust hood 1 away from the pressure block 4 is aligned with the slider 14 and snapped in, and then the dust hood 1 is pushed, and the protrusion 5 can be easily snapped into the groove. The pressure block 4 is positioned by the protrusion 5 so that the connecting plate 8 is just aligned with the connecting groove 9. At this time, it is only necessary to rotate the latch 12 so that the locking block 24 is rotated to the bottom of the locking groove 27 and aligned. Since the locking block 24 no longer abuts the connecting block 25 at this time, the connecting block 25 can fall under the action of gravity, driving the connecting plate 8 to be snapped into the inside of the connecting groove 9.

[0049] When the connecting plate 8 is inserted into the connecting groove 9, the inclined surface 15 will fit with the guiding inclined surface 19, and then the staff will press the connecting block 25 downward, so that the connecting plate 8 is pressed down accordingly. Under the guiding action of the inclined surface 15 and the guiding inclined surface 19, the pressure rod 11 will be forced to retreat until it completely enters the clamping hole 32, and the connecting plate 8 will continue to move downward. During the process of the pressure rod 11 being forced to retreat, the pressure plate 22 will squeeze the elastic member 20 accordingly, so that the elastic member 20 generates elastic force. When the connecting plate 8 moves down to the bottom of the connecting groove 9, the slot 26 is just aligned with the clamping hole 32. At this time, since the connecting plate 8 no longer abuts the pressure rod 11, the elastic member 20 returns to its original state and drives the pressure rod 11 to be clamped into the slot 26. The connection plate 8 is limited by the pressure rod 11, so that the connecting plate 8 cannot be separated from the connecting groove 9. Finally, the hair dryer 6 and the vacuum cleaner 7 are started at the same time to remove the dust in the dust hood 1.

[0050] When the dust hood 1 needs to be maintained and repaired, first, the two pressure rods 11 need only be pulled in the direction away from the connecting plate 8 to release the limit of the pressure rods 11 on the connecting plate 8, then the connecting block 25 is lifted upward, the bayonet 12 and the locking block 24 are inserted into the through hole 28 and the locking groove 27 until the locking block 24 completely passes through the locking groove 27, and then the bayonet 12 is rotated so that the locking block 24 can abut against the bottom surface of the connecting block 25. The locking block 24 limits the connecting block 25 so that the connecting block 25 will not fall under the action of gravity. By pushing the dust hood 1 in the reverse direction, the dust hood 1 can be easily removed from the railing 3 for maintenance and repair, which is easy to operate and saves time and effort.

[0051] The above shows and describes the basic principles, main features and advantages of the utility model.
