Description

Technical Field

[0001] The utility model belongs to the technical field of heavy-duty quantitative feeders, in particular to a heavy-duty quantitative feeder. Background Art

[0002] Feeding equipment is an auxiliary equipment in the mechanized storage and transportation system of lime production enterprises. Its main function is to continuously and evenly feed processed or unprocessed materials from a certain equipment to the receiving equipment or transportation machinery. In addition, it is also widely used in cement, mining, building materials, grain, chemical and other industries. It is known for its advanced technology, stable and reliable, high cost performance and durability. It is a high-tech product that integrates transportation, weighing and quantitative control.

[0003] After a long period of transporting materials, the belts of current heavy-duty quantitative feeders tend to become stretched and loose due to long-term use. The materials will squeeze the belts and cause depressions during transportation, which can easily cause the belts to hit the support rollers and rotating rollers, causing the materials to bump on the belts or even fall out of the entire device, thus preventing the materials from being transported normally. In addition, when current heavy-duty quantitative feeders are transporting materials with a lot of dust, a lot of dust will leak from the discharge port, causing air pollution on site. Even if on-site personnel wear masks, they will inhale a small amount of dust, which affects their health. Moreover, after transporting the materials, a small amount of floating dust will remain on the belt, affecting the subsequent transportation of other materials by the entire device. In view of this, we propose a heavy-duty quantitative feeder. Utility Model Content

[0004] The purpose of the present utility model is to provide a heavy-duty quantitative feeder to solve the problems raised in the above background technology.

[0012] The exhaust component is arranged at the air outlet of the collection box and is used to suck out the air in the collection box and discharge it to the outside after being filtered by the second filter.

[0013] In this technical solution, when workers find that the belt is in a loose state, the regulating component is set up, and the regulating component drives the adjusting roller to move downward. Under the action of extrusion, the adjusting roller will squeeze the belt downward, causing the belt to gradually tighten until the belt is in a taut state on the two rotating rollers, two driven rollers and several support rollers of the adjusting roller. The control of the regulating component is stopped. At this time, the belt can transport materials normally in the shell, and the material will not be dented on the belt, so that the material will no longer be bumped due to hitting the support rollers and rotating rollers.

[0014] Then when one of the rotating rollers rotates, one of the rotating rollers drives the other rotating roller, the adjusting roller, several supporting rollers and two driven rollers to rotate through the belt, so that the belt can rotate normally in the shell. At this time, the worker puts the material into the feed hopper and at the same time pulls the frame so that the frame slides in the slide. The frame drives the folding cover to extend until the frame is inserted into the slot. Then stop pulling the frame so that the folding cover is placed above the belt.

Under the action of air pressure, the two blades on the check valve will rotate in the direction of the exhaust assembly. At the same time, the air in the discharge hood will carry the dust through the filter and enter the collection box through the check valve. At the same time, the material enters the discharge hood under the transportation of the belt and falls. The dust generated therein is all sucked into the collection box. Then, under the continuous absorption of the exhaust assembly, the air in the collection box is always sucked into the exhaust assembly. At this time, the air carrying dust entering the collection box will first pass through the filter, so that the material is filtered out by the filter, and the air will be It is sucked into the collection box and discharged to the outside through the exhaust component, and the dust filtered by the second filter will fall into the collection box, and an appropriate amount of water will be added to the collection box to ensure that the dust can dissolve in the water and will not fly again. When the dust removal work is completed, the exhaust component is closed. At this time, the negative pressure phenomenon in the collection box gradually disappears. Under the action of elastic force, the torsion spring inside the check valve will drive the two blades to rotate toward the outer shell until the blades close the air outlet of the discharge hood. At this time, the worker can pull the collection box out of the collection box and then clean the dust in the collection box. This process ensures that when the material is fed into the outlet of the outer shell, no dust will float out from the discharge hood, ensuring that the on-site air environment is not polluted and ensuring the health of the workers.

The tops of the two bevel gears 1 are fixedly mounted with threaded rods that pass through the top of the inner cavity of the adjusting box, and the upper ends of the two threaded rods extend into the two U-shaped grooves and pass through the two ends of the slider 1 respectively.

[0022] In this technical solution, the plug is first pulled upward to make it slide up in the adjustment box until the lower end of the plug leaves the limiting hole of the transmission rod, releasing the restriction on the transmission rod. Then, the handle is turned, and the handle drives the transmission rod to rotate, and the transmission rod drives the two gears 2 to rotate. Under the action of meshing, the two bevel gears 2 drive the corresponding bevel gear 1 to rotate, and the two bevel gears 1 drive the corresponding threaded rods to rotate. Under the action of the threads, the two threaded rods jointly drive the slider 1 to move downward between the two fixed columns. At the same time, the slider 1 drives the adjusting roller downward through the two supporting columns to ensure that the adjusting roller can squeeze the belt to move downward, so that the belt is gradually tightened. When the belt is in a taut state, stop turning the handle. hand, and insert the plug into the adjusting box until the lower end of the plug is inserted into the corresponding limit hole on the transmission rod. At the same time, when the belt starts to transport materials, a small amount of floating dust will remain on the belt. At this time, when the belt passes through the adjusting roller, under the action of extrusion, the adjusting roller will squeeze the belt so that it is in continuous contact with the brush. At the same time, the brush will also clean the floating dust attached to the belt. The amount of floating dust swept down is small and has a certain weight and will not float into the air. Under the action of gravity, the swept floating dust will fall to the ground. This process ensures that the belt can recover from the relaxed state to the tight state under the control of the regulating component, and ensures that the belt can remain clean and can transport materials normally when transporting the next material.

[0028] In this technical solution, it is ensured that the dust in the discharge hood can be normally sucked into the collection box, that the material will not enter the collection box through the filter one, that the dust can be filtered out when passing through the filter two, and that the dust will fall into the collection box and dissolve in the water.

[0029] In the above technical solution, further, the exhaust component includes:

[0030] The exhaust duct is threadedly connected to the air outlet of the collection box, and an exhaust hood is fixedly installed on one end of the exhaust duct;

[0031] The motor is arranged in the exhaust duct, and a plurality of fixing rods fixed to the inner wall of the exhaust duct are fixedly installed on the peripheral side of the motor, and the plurality of fixing rods are distributed in a circular shape with equal intervals, and a fan is fixedly installed on the output shaft of the motor.

[0032] In this technical solution, the motor is connected to the power supply and started, and the output shaft of the motor drives the fan to rotate. When the fan rotates, the air in the collection box will be discharged to the outside through the exhaust pipe and the exhaust hood, causing a negative pressure phenomenon in the collection box, so that the dust in the discharge hood is sucked into the collection box through the air outlet of the discharge hood, ensuring that the exhaust component can normally suck the air carrying dust in the discharge hood into the collection box.

[0033] In the above technical solution, further comprising:

The speed-regulating motor drives one of the rotating rollers to rotate, and one of the rotating rollers drives another rotating roller, an adjustment roller, several support rollers and two driven rollers to rotate through a belt, so that the belt can rotate normally in the shell. Under the transmission of the belt, the material will pass over the weighing sensor and produce an extrusion effect, so that the weighing sensor can sense the specific weight of the material, and the weighing sensor will transmit the measured material data to the intelligent controller. The intelligent controller calculates the data and determines how many revolutions the output shaft of the speed-regulating motor needs to rotate per second. The intelligent controller controls the speed of the speed-regulating motor to ensure that the speed of one of the rotating rollers driven by the output shaft of the speed-regulating motor can reach a reasonable state, thereby controlling the speed of the belt transporting the material and ensuring that the material in the feed hopper can be reasonably and quantitatively transmitted through the belt; ensuring that the output shaft of the speed-regulating motor can normally drive one of the rotating rollers to rotate and ensure that the output shaft of the speed-regulating motor can rotate normally in the shell.

[0038] The beneficial effects of the utility model are:

[0039] 1. This heavy-duty quantitative feeder, through the provided adjusting roller and regulating assembly, can squeeze the stretched and relaxed belt downward, causing the belt to be gradually tightened until the belt is in a taut state on the adjusting roller, two rotating rollers, two driven rollers and several support rollers. This ensures that when the entire device is transporting materials, the materials will not be squeezed downward by gravity under the action of the belt and cause depression, which will then cause the belt to hit the rotating roller and support roller, avoiding affecting the normal material transportation of the entire device.

[0040] 2. The heavy-duty quantitative feeder, when transporting materials, uses the folding cover provided. When the entire device transports materials, the mobile frame slides in the slide and is inserted into the card slot. The frame drives the folding cover to extend, so that the folding cover is sleeved above the belt, thereby preventing the device from having dust flying out from the belt when transporting materials. At the same time, through the cooperation of the exhaust assembly, the discharge cover and the collection box, it is ensured that the air carrying dust in the discharge cover can be filtered by the filter screen 1 to prevent the material from entering the collection box, and the dust-carrying air will be sucked into the collection box and then filtered by the filter screen 2 to ensure that the dust in the air can be filtered and collected. The dust collected in the collection box ensures that when the entire device is transporting materials, no dust will leak out from the discharge port of the outer shell, which will pollute the air environment and ensure the health of the workers. In addition, after the belt transports the material out of the entire device, a small amount of floating dust will remain on the belt. When the belt passes through the adjusting roller, the belt will continue to contact with the brush, so that the brush can clean the floating dust remaining on the belt. The amount of floating dust swept down is small and has a certain weight and will not float into the air. Under the action of gravity, the swept floating dust will fall to the ground, thereby ensuring that the belt can remain clean and can transport materials normally when transporting the next material.

[0057] Example 1:

[0058] See also Figures 1-9 As shown, this embodiment provides a heavy-duty quantitative feeder, comprising:

[0059] The housing 1 has a feed hopper 2 fixedly mounted on the top, a discharge cover 24 fixedly mounted at the discharge port of the housing 1, and a through slot formed at the bottom of the housing 1;

[0060] Two rotating rollers 5 are rotatably mounted in the housing 1 near the inlet and outlet thereof, and an adjusting roller 13, two driven rollers 51 and a plurality of supporting rollers 7 are rotatably mounted in the housing 1;

[0061] Belt 6, belt 6 is installed on the adjusting roller 13, two rotating rollers 5 and several supporting rollers 7, and the belt 6 is in contact with two driven rollers 51;

[0062] The regulating component is located on the housing 1 and is used to adjust the position of the regulating roller 13 to move up and down;

[0063] A chute 22 is provided at the top of the housing 1 and is located between the feed hopper 2 and the discharge cover 24. A frame 21 is slidably mounted in the chute 22. A folding cover 20 fixed to the feed hopper 2 is fixedly mounted on one side of the frame 21. A slot 23 is provided on the housing 1 at a position away from the frame 21.

[0064] The collecting box 25 is fixedly mounted on the discharge cover 24. A filter screen 28 and a check valve 29 are fixedly mounted at the air outlet of the discharge cover 24. A collecting box 30 is slidably mounted in the collecting box 25. A filter screen 2 31 is fixedly mounted in the air outlet of the collecting box 25.

[0065] The exhaust component is arranged at the air outlet of the collection box 25 and is used to suck out the air in the collection box 25 and discharge it to the outside after being filtered by the filter screen 31.

[0066] Among them, when the worker finds that the belt 6 is in a loose state, the regulating component is set up, and the regulating component drives the adjusting roller 13 to move downward. Under the action of extrusion, the adjusting roller 13 will squeeze the belt 6 downward, so that the belt 6 is gradually tightened until the belt 6 is in a taut state on the two rotating rollers 5, two driven rollers 51 and several supporting rollers 7 of the adjusting roller 13. The control of the regulating component is stopped. At this time, the belt 6 can transport materials normally in the shell 1, and the material will not be dented on the belt 6, so that the material will no longer be bumped due to hitting the supporting roller 7 and the rotating roller 5.

[0067] Then when one of the rotating rollers 5 rotates, one of the rotating rollers 5 drives the other rotating roller 5, the adjusting roller 13, several supporting rollers 7 and two driven rollers 51 to rotate through the belt 6, so that the belt 6 can rotate normally in the shell 1. At this time, the worker puts the material into the feed hopper 2 and, at the same time, pulls the frame 21 so that the frame 21 slides in the chute 22. The frame 21 drives the folding cover 20 to extend until the frame 21 is inserted into the card slot 23. Then, the frame 21 is stopped from being pulled so that the folding cover 20 is placed above the belt 6.

[0068] Then, through the exhaust assembly, the air in the collection box 25 is sucked into the exhaust assembly and discharged to the outside, causing a negative pressure phenomenon in the collection box 25. Under the action of air pressure, the two blades on the check valve 29 will rotate in the direction of the exhaust assembly. At the same time, the air in the discharge hood 24 will carry dust through the filter 28 and enter the collection box 25 through the check valve 29. At the same time, the material enters the discharge hood 24 under the transportation of the belt 6 and falls. The dust generated therein is all sucked into the collection box 25. Then, under the continuous absorption of the exhaust assembly, the air in the collection box 25 is constantly sucked into the exhaust assembly. At this time, the air carrying dust entering the collection box 25 will first be filtered through the filter 28, so that the material is filtered out by the filter 28, and the air will The dust is sucked into the collection box 25 and discharged to the outside through the exhaust component, and the dust filtered by the filter 31 will fall into the collection box 30, and an appropriate amount of water will be added to the collection box 30 to ensure that the dust can dissolve in the water and will not fly again. When the dust removal work is completed, the exhaust component is closed. At this time, the negative pressure phenomenon in the collection box 25 gradually disappears. Under the action of elastic force, the torsion spring inside the check valve 29 will drive the two blades to rotate in the direction of the outer shell 1 until the blades close the air outlet of the discharge cover 24. At this time, the worker can pull the collection box 30 out of the collection box 25 and then clean the dust in the collection box 30. This process ensures that when the material is fed into the discharge port of the outer shell 1, no dust will float out from the discharge cover 24, ensuring that the on-site air environment is not polluted and ensuring the health of the workers.

[0069] It is worth noting that the folding cover 20 is made of elastic material. When the folding cover 20 is extended by the frame 21, in the absence of external force, the folding cover 20 can automatically shrink under the action of its own elastic force. A small amount of water is placed in the collection box 30 to ensure that the dust in the collection box 25 can be dissolved in the water and will not be allowed to fly again.

Under the action of the thread, the two threaded rods 10 jointly drive the slider 11 to move downward between the two fixed columns 9. At the same time, the slider 11 drives the adjusting roller 13 to move downward through the two support columns 12, ensuring that the adjusting roller 13 can squeeze the belt 6 to move downward, so that the belt 6 is gradually tightened. When the belt 6 is in a taut state After the belt 6 is in the state, stop turning the handle 19 and insert the plug 18 into the adjusting box 8 until the lower end of the plug 18 is inserted into the corresponding limit hole on the transmission rod 17. At the same time, when the belt 6 starts to transport materials, a small amount of floating dust will remain on the belt 6. At this time, when the belt 6 passes through the adjusting roller 13, under the action of extrusion, the adjusting roller 13 will squeeze the belt 6 so that it is in continuous contact with the brush 14. At the same time, the brush 14 will also clean the floating dust attached to the belt 6. The amount of floating dust cleaned is small and has a certain weight and will not float into the air. Under the action of gravity, the cleaned floating dust will fall to the ground. This process ensures that the belt 6 can be restored to the tight state from the relaxed state under the control of the regulating component, and ensures that the belt 6 can remain clean and can transport materials normally when transporting the next material.

[0093] Example 8:

[0094] This embodiment provides a heavy-duty quantitative feeder, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0095] The weighing sensor 4, the intelligent controller 41, and the speed regulating motor 3 are all fixedly mounted on one side of the housing 1. The output shaft of the speed regulating motor 3 passes through one side of the housing 1 and is coaxially connected to one of the rotating rollers 5. The output shaft of the speed regulating motor 3 is rotationally connected to the housing 1.

[0096] Among them, the speed regulating motor 3, the weighing sensor 4 and the intelligent controller 41 are connected to the power supply and started. The speed regulating motor 3 drives one of the rotating rollers 5 to rotate. One of the rotating rollers 5 drives the other rotating roller 5, the adjustment roller 13, several supporting rollers 7 and two driven rollers 51 to rotate through the belt 6, so that the belt 6 can rotate normally in the shell 1. Under the transmission of the belt 6, the material will pass over the weighing sensor 4 and produce a squeezing effect, so that the weighing sensor 4 can sense the specific weight of the material, and the weighing sensor 4 will transmit the measured material data to the intelligent controller 41. The intelligent controller 41 calculates the number of revolutions per second required by the output shaft of the speed regulating motor 3 through the calculated data, and controls the speed of the speed regulating motor 3 to ensure that the speed of the output shaft of the speed regulating motor 3 drives one of the rotating rollers 5 to reach a reasonable state, thereby controlling the speed of the belt 6 to transport the material, and ensuring that the material in the feed hopper 2 can be reasonably and quantitatively transmitted through the belt 6; ensuring that the output shaft of the speed regulating motor 3 can normally drive one of the rotating rollers 5 to rotate, and ensuring that the output shaft of the speed regulating motor 3 can rotate normally in the shell 1.

[0097] It is worth noting that the weighing sensor 4, intelligent controller 41, and speed-regulating motor 3 involved in the present utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present utility model does not involve improvements to the structure and working principle of the weighing sensor 4, intelligent controller 41, and speed-regulating motor 3.

[0098] Example 9:

[0099] This embodiment provides a heavy-duty quantitative feeder, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features: one end of the weighing sensor 4 passes through one side of the shell 1 and extends into the shell 1, and the top of the weighing sensor 4 is on the same horizontal line as the top of the rotating roller 5 and the top of the supporting roller 7.

[0100] Among them, it is ensured that the weighing sensor 4 can normally measure the weight of the material passing through the top of the weighing sensor 4, and it is ensured that the top of the weighing sensor 4 can contact the bottom of the belt 6 and can normally measure the weight of the material passing through the top of the weighing sensor 4.

[0101] Working principle: When the worker checks that the belt 6 is in a loose state, the worker can first pull the plug 18 upward to make the plug 18 slide up in the adjustment box 8 until the lower end of the plug 18 leaves the limit hole of the transmission rod 17, releasing the restriction on the transmission rod 17, and then turn the handle 19. The handle 19 drives the transmission rod 17 to rotate, and the transmission rod 17 drives the two bevel gears 2 16 to rotate. Under the action of meshing, the two bevel gears 2 16 drive the corresponding bevel gear 1 15 to rotate, and the two bevel gears 15 drive the corresponding threaded rod 10 to rotate. Under the action of the thread, the two threaded rods 10 jointly drive the slider 11 downward between the two fixed columns 9. The sliding block 11 drives the adjusting roller 13 to move downward through the two supporting columns 12, so that the adjusting roller 13 squeezes the belt 6 to move downward. Under the action of squeezing, the belt 6 can be slowly tightened until the belt 6 is in a taut state on the adjusting roller 13, the two driven rollers 51 of the two rotating rollers 5 and the supporting rollers 7. Then, the handle 19 is stopped and the plug 18 is inserted into the adjusting box 8 until the lower end of the plug 18 is inserted into the corresponding limit hole on the transmission rod 17. At this time, the belt 6 can transport the material normally in the housing 1, and the material will not be dented on the belt 6, so that the material will no longer be bumped due to hitting the supporting rollers and the rotating rollers.

[0102] Subsequently, the speed regulating motor 3, the weighing sensor 4 and the intelligent controller 41 are connected to the power supply and started. The speed regulating motor 3 drives one of the rotating rollers 5 to rotate, and one of the rotating rollers 5 drives the other rotating roller 5, the adjusting roller 13, several supporting rollers 7 and two driven rollers 51 to rotate through the belt 6, so that the belt 6 can rotate normally in the shell 1. At this time, the worker puts the material into the feed hopper 2. Under the transmission of the belt 6, the material will pass over the weighing sensor 4 and produce an extrusion effect, so that the weighing sensor 4 can sense the specific weight of the material, and the weighing sensor 4 will transmit the measured material data to the intelligent controller 41. The intelligent controller 41 calculates the result of how many revolutions the output shaft of the speed regulating motor 3 needs to rotate per second through the calculated data, and allows the intelligent controller 41 to control the speed of the speed regulating motor 3 to ensure that the speed of one of the rotating rollers 5 driven by the output shaft of the speed regulating motor 3 can reach a reasonable state, thereby controlling the speed of the belt 6 to transport the material, and ensuring that the material in the feed hopper 2 can be reasonably and quantitatively transmitted through the belt 6.

[0103] When the entire device starts to transport materials, workers can push the frame 21 to move in the slide 22. The frame 21 drives the folding cover 20 to move and causes the folding cover 20 to start stretching. The frame 21 is stopped from moving until it is inserted into the slot 23, so that the folding cover 20 can cover the belt 6 to prevent dust from drifting from the belt 6 into the air. This process ensures that when the entire device transports dusty materials, dust will not drift into the on-site environment during the transportation process.

[0104] At the same time, the motor 33 is powered on and started, and the output shaft of the motor 33 drives the fan 32 to rotate. When the fan 32 rotates, the air in the collection box 25 is discharged to the outside through the exhaust pipe 26 and the exhaust hood 27, so that a negative pressure phenomenon occurs in the collection box 25. Under the action of air pressure, the two blades on the check valve 29 will rotate in the direction of the exhaust pipe 26. At the same time, the air in the discharge hood 24 will carry dust through the filter 28 and enter the collection box 25 through the check valve 29. At the same time, the material enters the discharge hood 24 under the transportation of the belt 6 and falls. The dust generated therein is all sucked into the collection box 25. Subsequently, under the continuous rotation of the fan 32, the air in the collection box 25 is always sucked into the exhaust pipe 26. At this time, the air carrying dust entering the collection box 25 will first be filtered through the filter 28, so that the material is The dust is filtered out by filter 1 28 , and the air is sucked into the collection box 25 and discharged to the outside through the exhaust hood 27 , and the dust filtered by filter 2 31 will fall into the collection box 30 , and an appropriate amount of water will be added to the collection box 30 to ensure that the dust can be dissolved in the water and will not fly again. When the dust removal work is completed, the motor 33 is turned off and the fan 32 also stops rotating. At this time, the negative pressure phenomenon in the collection box 25 gradually disappears. Under the action of elastic force, the torsion spring inside the check valve 29 will drive the two blades to rotate toward the direction of the outer shell 1 until the blades close the air outlet of the discharge hood 24. At this time, the worker can pull the collection box 30 out of the collection box 25 and then clean the dust in the collection box 30. This process ensures that when the material is fed into the discharge port of the outer shell 1, no dust will float out from the discharge hood 24, ensuring that the on-site air environment is not polluted and ensuring the health of the workers.

[0105] After the belt 6 transports the material out of the overall device, a small amount of floating dust will remain on the belt 6. When the belt 6 passes through the adjusting roller 13, under the action of squeezing, the adjusting roller 13 will squeeze the belt 6 so that it is in continuous contact with the brush 14. At the same time, the brush 14 will also clean the floating dust attached to the belt 6. The amount of floating dust cleaned down is small and has a certain weight and will not float into the air. Under the action of gravity, the cleaned floating dust will fall to the ground. This process ensures that the belt 6 can remain clean and can transport materials normally when transporting the next material.
