Description

[0002] In the coal mining industry, efficient and stable coal transportation is the key link to guarantee production efficiency and economic benefits, and the conveyor, as the core equipment of coal transportation, undertakes the continuous material conveying task from the underground mining face to the surface processing and storage area. With the continuous expansion of coal mining scale and the increase of mining depth, higher requirements are put forward for the performance and reliability of the conveyor.

[0003] When the coal is transported from the underground mining to the ground by the conveyor, it needs to be transferred from one transmission section to another. The transfer process of the conventional conveyor is to directly drop the coal vertically from the end of the transmission belt of the previous conveyor to the feed pipe of the next conveyor, and then transmit it again by the transmission belt. When the coal is transferred from one conveyor to another, the sudden change of material flow rate at the transfer point can easily cause material accumulation. For example, the front conveyor has a higher speed, while the rear conveyor has a slower speed, and the coal will form a jam due to the speed difference at the moment of transfer. In addition, during the coal mining process, the mining methods such as blasting result in different sizes of coal particles, and large particles of coal are prone to collide with the transfer structure or get stuck when passing through the transfer point, thereby hindering the normal conveying of subsequent coal.

Specific implementation

[0025] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings of the specification of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0026] Refer to Figure 3 , Figure 5 and Figure 6The utility model provides a kind of embodiment: a coal mine is used with mine conveyor, including feed pipe 1, the inner wall of feed pipe 1 is fixedly connected with multiple spring 2 and welding plate 6, the top of spring 2 is fixedly connected with load-bearing plate 3, the bottom of load-bearing plate 3 is fixedly connected with pillar 4 and spring steel 7, the bottom of spring steel 7 is fixedly connected with welding column 22, the bottom of feed pipe 1 is fixedly connected with shell 5, the inner wall of shell 5 is fixedly connected with motor 8 and hinged block 12, the output of motor 8 is fixedly connected with rotating rod 9, the outer wall of rotating rod 9 is fixedly connected with ratchet wheel 10, the outer wall of rotating plate 11 is rotatably connected with rotating plate 11, the outer wall of rotating plate 11 is fixedly connected with connecting column 15, hinged column 17 and sliding block 18, the outer wall of hinged block 12 is rotatably connected with function plate 13, the outer wall of hinged block 12 and hinged column 17 is hingedly connected with hinged spring 14, the outer wall of connecting column 15 is rotatably connected with pawl 16, the outer wall of sliding block 18 is slidably connected with sliding plate 19, dust suction assembly is arranged on the left side of feed pipe 1, transmission groove is opened and penetrates in the inner wall of feed pipe 1, transmission belt 29 is slidably connected in transmission groove, the bottom of transmission belt 29 is slidably connected on the upper surface of load-bearing plate 3.

[0027] Specifically, under normal conditions, coal first slides from the opening directly above feed pipe 1 and falls onto the transmission belt 29 on load-bearing plate 3, and the spring 2 and spring steel 7 installed at the bottom of load-bearing plate 3 serve as a buffer to prevent damage to the feed pipe 1 caused by the impact of coal during long-term use. The transmission belt 29 passes through the transmission groove in the inner wall of the feed pipe 1, which serves to transport the coal. When the coal blocks the feed pipe 1, causing the pressure on the load-bearing plate 3 to increase, the load-bearing plate 3 will descend with the lower pillar 4, and the bottom of the pillar 4 will touch the function plate 13, causing the hinged spring 14 to compress and rotate around the pivot point. This causes the pawl 16 to rotate around the connecting column 15 under the pressure of the other hinged spring 14 and engage with the ratchet wheel 10. Under normal conditions, the ratchet wheel 10 will rotate with the rotating rod 9 under the action of the motor 8. When the ratchet wheel 10 and the pawl 16 engage, the pawl 16 will be driven to rotate, which in turn drives the rotating plate 11 to rotate. The rotating plate 11 drives the sliding block 18 to rotate and slide on the inner wall of the sliding plate 19, which drives the sliding plate 19 to move up and down, thereby driving the spring steel 7 and the load-bearing plate 3 to move synchronously. The spring steel 7 serves as a buffer to prevent the transmission from being affected by excessive vibration.

[0028] Refer to Figure 1 And Figure 7The dust suction assembly comprises a protective shell 30 fixedly connected to the left side of the outer wall of the feeding pipe 1, a worm 31 rotatably connected to the inner wall of the protective shell 30 and penetrating through the protective shell 30, a driving rod 33 fixedly connected to the inner wall of the protective shell 30, a worm wheel 32 fixedly connected to the outer wall of the driving rod 33, a fan 34 installed on the inner wall of the protective shell 30, one end of the driving rod 33 fixedly connected to the input end of the fan 34, a dust collector 37 fixedly connected to the inner wall of the protective shell 30 and penetrating through the protective shell 30, a dust suction groove formed in the inner wall of the feeding pipe 1, the opening of the dust collector 37 fixedly connected in the dust suction groove, a collecting groove 36 slidably connected to the inner wall of the protective shell 30, a belt pulley fixedly connected to the outer wall of the transmission rod 27 and the worm 31, a belt sleeved on the outer wall of the two belt pulleys, the worm 31 and the worm wheel 32 in meshing connection, a plurality of filter pads 35 fixedly connected to the inner wall of the protective shell 30, and a plurality of filter grooves formed in the inner wall of the protective shell 30 and in which the filter pads 35 are installed.

[0029] Specifically, the protective shell 30 plays a role of fixing and protecting the internal components. When the motor 26 drives the transmission rod 27 to rotate, power transmission is realized through the belt pulleys and the belt sleeved on the transmission rod 27 and the worm 31, so that the worm 31 is driven to rotate, the worm 31 drives the worm wheel 32 to rotate through meshing, and the driving rod 33 rotatably connected to the inner wall of the protective shell 30 is driven to rotate, the driving rod 33 being fixedly connected to the input end of the fan 34. When the fan 34 is driven to rotate, air flows rapidly in the closed environment inside the protective shell 30, forming a relatively low-pressure area, that is, a negative pressure environment. According to Bernoulli's principle, the pressure is small where the flow rate is fast, and the pressure is large where the flow rate is slow. Therefore, the pressure inside the protective shell 30 is reduced, while the atmospheric pressure outside is relatively high, thereby forming a pressure difference. Under the action of this pressure difference, the dust on the coal falls through the feeding pipe 1 and is sucked into the protective shell 30 by the dust collector 37. The air containing dust is filtered through the filter pads 35, the dust particles are intercepted on the filter pads 35 and fall into the collecting groove 36, and the purified air is discharged from the filter pads 35 on the left side of the protective shell 30, thereby achieving the effect of dust suction.

[0030] With reference to Figure 4 and Figure 5 , the opposite side of the two welding plates 6 is fixedly connected with a load-bearing column, and the two ends of the spring steel 7 are rotatably connected to the outer wall of the load-bearing column.

[0031] Specifically, the load-bearing column fixedly installed on the opposite side of the welding plate 6 is rotatably connected to the two ends of the spring steel 7, so that the spring steel 7 can always move vertically around the load-bearing column in the welding plate 6 during compression, thereby ensuring the stability.

[0032] With reference to Figures 4-6The inner wall of the feeding pipe 1 and the outer wall of the shell 5 are provided with a plurality of working grooves, the outer wall of the support column 4 is slidably connected in one of the working grooves, one end of the functional plate 13 is circular, the circular part is located directly below the support column 4, the outer wall of the functional plate 13 is attached to one of the hinge springs 14, the top end of the functional plate 13 is slidably connected to the left end of the pawl 16, the outer wall of the pawl 16 is attached to one of the hinge springs 14, the connecting column 15 and the hinge column 17 are fixedly connected to the front side of the outer wall of the rotating plate 11, the sliding plate 19 is fixedly connected to the rear side of the outer wall of the rotating plate 11, the inner wall of the welding plate 6 is fixedly connected to the limiting column 21, the inner wall of the feeding pipe 1 and the outer wall of the sliding plate 19 are both fixedly connected to the limiting block 20, one of the limiting blocks 20 is slidably connected to the outer wall of the limiting column 21, and the welding column 22 is slidably connected to the inner wall of one of the limiting blocks 20.

[0033] Specifically, the working grooves of the feeding pipe 1 and the shell 5 penetrate each other, the outer wall of the support column 4 is slidably connected in one of the working grooves, which ensures that it can extrude the functional plate 13 to trigger the vibration assembly when it is too heavy, and at the same time, the shell 5 protects and fixes the internal components. When the gravity is too large, the support column 4 extrudes the functional plate 13 to descend, the outer wall of the functional plate 13 extrudes the hinge spring 14, rotates around the hinge point, the top end of the functional plate 13 is separated from the pawl 16, the top end of the pawl 16 rotates around the hinge column 17 under the extrusion of the hinge spring 14 installed on the hinge column 17, and engages with the ratchet wheel 10. The elastic force of the hinge spring 14 ensures the resetting of the device. Since the ratchet wheel 10 is always rotating under the action of the motor 8, when the functional plate 13 engages with the ratchet wheel 10, the left end of the functional plate 13 will push against the hinge column 17, drive the hinge column 17, and then drive the rotating plate 11 to rotate. When the rotating plate 11 rotates, the sliding block 18 fixedly connected to the rear side of the outer wall of the rotating plate 11 rotates synchronously. Since the sliding block 18 is slidably connected to the inner wall of the sliding plate 19, and the outer wall of the sliding plate 19 is limited by the limiting block 20 on the limiting column 21, the sliding plate 19 will move vertically along the limiting column 21, thereby driving the welding column 22 at the top to move up and down, achieving the effect of driving the bearing plate 3 and the transmission belt 29 to vibrate up and down.

[0034] With reference to Figure 1 and Figure 2 The bottom end of the feeding pipe 1 is fixedly connected with a plurality of shelf plates 23, both ends of the shelf plate 23 are fixedly connected with rotating plates 24, the opposite side of the two rotating plates 24 is rotatably connected with transmission wheels 28, the outer wall of the two transmission wheels 28 is sleeved with a transmission belt 29, the outer wall of the left rotating plate 24 is fixedly connected with a motor table 25, the upper surface of the motor table 25 is fixedly connected with a motor 26, the output end of the motor 26 is fixedly connected with a transmission rod 27, and the rear end of the transmission rod 27 is fixedly connected to the inner wall of one of the transmission wheels 28.

[0035] Specifically, the feeding pipe 1 is fixed and supported by the frame plate 23, and the frame plate 23 is further fixed and supported by the rotating plate 24, so that the whole conveyor is stable. The transmission wheel 28 is connected to the rotating plate 24, and the motor 26 drives the transmission rod 27 to rotate and drive one of the transmission wheels 28 to rotate. The transmission belt 29 is used to transmit power to move the coal on the transmission belt 29. The transmission belt 29 has protective plates at both ends to prevent the coal from falling during transmission. The rotating rod 9 driven by the motor 8 can be sleeved with a belt pulley and a belt, and the other belt pulley is sleeved on the transmission rod 27 to assist the rotation of the transmission rod 27 and drive the transmission belt 29 to transmit the coal.

[0036] Working principle: when the coal is transferred by the coal conveyor, the motor 8 and the motor 26 are started first. When the transmission belt 29 starts to work, the coal is received from the feeding pipe 1. Under normal circumstances, the coal falls directly into the transmission belt 29 on the supporting plate 3 along the feeding pipe 1, and is transmitted into the next stage along with the transmission belt 29. When the coal falls vertically, the supporting plate 3 first bears the falling force, and then the gravity is dispersed to the spring 2 for buffering, so as to prevent the gravity of the coal from damaging the feeding pipe 1 for a long time.

[0037] At the same time, the motor 26 drives the transmission rod 27 to rotate, and the power is transmitted to the worm 31 through the synchronous wheel and the belt sleeved on the transmission rod 27. The worm 31 is driven to rotate, and the worm 32 is driven to rotate through the meshing relationship. Since the worm 32 is fixedly connected to the driving rod 33, the driving rod 33 is driven to rotate and transmits power to the fan 34. At this time, the fan 34 starts to rotate. Since the filter pad 35 is installed, the working environment of the fan 34 is relatively sealed. The rotation of the fan 34 impeller makes the air flow quickly, forming a relatively low pressure area, that is, a negative pressure environment, in the protective shell 30. The air flow in the protective shell 30 is accelerated, and the pressure is reduced, while the atmospheric pressure outside is relatively high, so that a pressure difference is formed. Under the action of the internal and external pressure difference, the dust on the coal is sucked into the protective shell 30 from the dust suction groove of the feeding pipe 1 by the dust collector 37, and after being filtered by the filter pad 35, it falls into the collection groove 36 and is collected. The air is discharged from the filter pad 35 at the rear side of the protective shell 30. After the collection groove 36 is extracted, the dust can be treated.

[0038] When the coal mine is blocked, the weight of the bearing plate 3 is increased, the bearing plate 3 is gradually extruded spring 2 and spring steel 7 and falls, drives the support 4 under the bearing plate 3 together with the bottom end of the support 4, the circular part of the function plate 13 is pressed, the hinge spring 14 is extruded and rotates around the hinge point, the pawl 16 originally blocked by the top end of the function plate 13 rotates around the connecting column 15 under the action of another hinge spring 14, the tip engages with the ratchet wheel 10, and rotates together with the ratchet wheel 10 under the action of 8, when the function plate 13 rotates, the left end will resist the hinge column 17, drive the hinge column 17 to rotate, when the hinge column 17 rotates, the sliding block 18 fixedly installed on the back of the hinge column 17 rotates, because the sliding plate 19 is sleeved on the outer wall of the sliding block 18, the sliding plate 19 will continuously move in the vertical direction under the limiting action of the limiting block 20 and the limiting column 21, and drive the welding column 22 fixedly connected at the top end to move, because the top end of the welding column 22 is fixedly connected with the spring steel 7, and the top end of the spring steel 7 is fixedly connected with the bearing plate 3, so that the bearing plate 3 will finally vibrate in the vertical direction, so that the coal mine blocked in the feeding pipe 1 is vibrated and continuously transported under the action of the conveying belt 29, and the problem of blockage is solved.

[0039] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be contained in the protection scope of the utility model.
