Description

Technical Field

[0001] This invention relates to the field of fabric technology, and in particular to a fabric trolley with a doorless unloading system and a built-in dust removal track that allows for arbitrary turning. Background Technology

[0002] The circular placing boom is a key piece of equipment widely used in stockpiles of bulk materials (such as ore, coal, cement clinker, and grain). In operation, materials are first fed into the placing boom via a feeding device, and then the boom moves to various placing points to discharge the materials. However, its core workflow—the feeding and discharging stages—generates significant dust emissions, causing environmental pollution and failing to meet increasingly stringent environmental standards and green production requirements. Summary of the Invention

[0003] This invention provides a gateless, unloading, and dust-collecting track-mounted concrete placing vehicle that can turn at any angle, in order to solve the problem of environmental pollution during the operation of a circular concrete placing vehicle.

[0004] This invention provides a doorless, turnable, dust-collecting track-mounted material distribution vehicle, including a material distribution bin. A material distribution cylinder is rotatably mounted inside the bin. A shaft on the material distribution cylinder is connected to a first motor. The upper and lower ends of the bin are respectively provided with an inlet and an outlet. The material distribution cylinder has a material distribution port that mates with the inlet and outlet. A first discharge trough is fixed below the material distribution port on the cylinder. Discharge plates are provided on both sides of the first discharge trough. A second discharge trough is formed between the upper surface of the discharge plate and the material distribution cylinder. A third discharge trough is formed between the lower surface of the discharge plate and the bottom of the material distribution cylinder. The first discharge trough is located at the upper end of the material distribution cylinder, the second discharge trough is located below the first discharge trough, and the third discharge trough is located at the lower end of the second discharge trough. A dust suction port is provided on the bin. A second channel is provided between the bin and the material distribution cylinder. The dust suction port is connected to the inlet and outlet through the second channel.

[0005] Preferably, the fabric bin is provided with a sealing mechanism below its inlet, and a sealing airbag is provided above its inlet, with the sealing airbag located outside the inlet of the fabric bin.

[0006] Preferably, the fabric bin is provided with a sealing cover below its discharge port, and a support frame is fixed to the bottom of the sealing cover. The support frame is connected to the lifting mechanism of the fabric bin.

[0007] Preferably, the bottom of the fabric bin is rotatably provided with a hinge shaft, the hinge shaft is fixed to the damper, and lifting rods are fixed at both ends of the hinge shaft. The lifting rods are fixed to the support frame by ropes.

[0008] Preferably, the sealing mechanism includes a sealing belt and two rollers, the sealing belt is sleeved on the two rollers, the rollers are connected to a second motor, and the sealing belt is provided with clearance holes adapted to the feed inlet.

[0009] Preferably, a surrounding plate is provided at the feed inlet, the surrounding plate is located between the two rollers, the surrounding plate is located inside the sealing belt, and sealing rings are provided above and below the surrounding plate, the sealing rings being in contact with the sealing belt.

[0010] Preferably, it also includes a support frame, and a weighing sensor is provided between the fabric bin and the support frame.

[0011] Preferably, a material discharge channel is formed between the first material discharge trough and the material discharge plate, and the sum of the widths of the two material discharge channels is less than or equal to the width of the first material discharge trough.

[0012] Preferably, the material discharge plate is inclined, with the higher end of the material discharge plate close to the first material discharge trough.

[0013] Preferably, the first material discharge trough includes two material distribution plates, the lower ends of which are fixed to a shaft inside the material distribution cylinder.

[0014] Compared with existing technologies, in this invention, when material falls into the feeding cylinder through the feed inlet of the feeding bin, the dust suction port removes dust from the feed inlet or inside the feeding cylinder through the second channel. When the feeding cylinder rotates so that its feeding inlet faces downward, the material inside the feeding cylinder falls into the furnace top bin through the discharge outlet, and the dust suction port removes dust from the feeding inlet to the discharge outlet through the second channel. The design of the feeding bin, feeding cylinder, second channel, and dust suction port ensures that dust generated during the feeding and unloading of the feeding cart can be removed, resulting in good dust collection and meeting environmental protection production requirements. Secondly, when material falls from the feed inlet, part of the material falls into the first discharge chute, and the other part falls into the third discharge chute through the first channel. This keeps the center of gravity of the feeding cylinder closer to the shaft rather than the bottom of the feeding cylinder. This structural design allows the first motor to rotate the feeding cylinder with a smaller torque. When the first discharge chute is full, the accumulated material forms a slope. Subsequent material falling onto the first discharge chute will mostly roll down the slope into the second discharge chute, thus rebalancing the material in the distribution cylinder. This structure helps to shift the center of gravity of the distribution cylinder upwards, closer to the shaft, allowing the first motor to rotate the distribution cylinder with less torque during distribution. Third, when the distribution cylinder is full of material, the center of gravity is close to the shaft, allowing the first motor to rotate the distribution cylinder with less torque. By providing a first, second, and third discharge chute, this invention ensures that even when the distribution cylinder is not full (e.g., half-full), its center of gravity remains close to the shaft, allowing the first motor to rotate the distribution cylinder with less torque.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] See attached document Figure 1 This invention provides a gateless, doorless, dust-collecting track-mounted material distribution vehicle with arbitrary turning capabilities, including a material distribution bin 1. A material distribution cylinder 2 is rotatably mounted inside the bin 1. A shaft 012 on the material distribution cylinder 2 is connected to a first motor 3. The first motor 3 drives the shaft 012 to rotate, thereby rotating the material distribution cylinder 2. The upper and lower ends of the bin 1 are respectively provided with an inlet 11 and an outlet 12. (Refer to attached drawing) Figure 3 and attached Figure 5 The fabric cylinder 2 is provided with a fabric inlet 21 that mates with the inlet 11 and the outlet 12. A first discharge trough 22 is fixed below the fabric inlet 21. Discharge plates 23 are provided on both sides of the first discharge trough 22. A second discharge trough 24 is formed between the upper end face of the discharge plate 23 and the fabric cylinder 2. A third discharge trough 25 is formed between the lower end face of the discharge plate 23 and the bottom of the fabric cylinder 2. The first discharge trough 22 is located at the upper end of the fabric cylinder 2, the second discharge trough 24 is located below the first discharge trough 22, and the third discharge trough 25 is located at the lower end of the second discharge trough 24. (Refer to attached diagram) Figure 2 The material feeding bin 1 is equipped with a dust suction port 100, and a second channel 300 is provided between the material feeding bin 1 and the material feeding cylinder 2. The dust suction port 100 is connected to the feed inlet 11 and the discharge outlet 12 through the second channel 300. In this invention, when the material falls into the material feeding cylinder 2 along the feed inlet 11 of the material feeding bin 1, the dust suction port 100 sucks away the dust at the feed inlet 11 or inside the material feeding cylinder 2 through the second channel 300. When the material feeding cylinder 2 rotates so that its feeding opening 21 faces downward, the material inside the material feeding cylinder 2 falls into the furnace top bin along the discharge outlet 12, and the dust suction port 100 sucks away the dust from the feeding opening 21 to the discharge outlet 12 through the second channel 300. The design of the material feeding bin 1, the material feeding cylinder 2, the second channel 300, and the dust suction port 100 ensures that the dust generated during the feeding and unloading of the material feeding cart can be sucked away, resulting in good dust collection effect and meeting the requirements of environmentally friendly production. Secondly, when material falls into the feed inlet 11, part of the material will fall into the first discharge chute 22, and the other part will fall into the third discharge chute 25 through the first channel 26. This allows the center of gravity of the fabric cylinder 2 to be closer to the shaft 012 rather than to the bottom of the fabric cylinder 2. This structural design allows the first motor 3 to rotate the fabric cylinder 2 with a smaller torque. (See attached diagram) Figure 8When the first discharge chute 22 is full, the accumulated material forms a slope. When subsequent material falls onto the first discharge chute 22, most of it rolls down the slope into the second discharge chute 24, thus rebalancing the material in the distribution cylinder 2. This structure helps to shift the center of gravity of the distribution cylinder 2 closer to the shaft 012, allowing the first motor 3 to rotate the distribution cylinder 2 with a smaller torque during material distribution. Third, when the distribution cylinder 2 is full of material, the center of gravity is close to the shaft 012, allowing the first motor 3 to rotate the distribution cylinder 2 with a smaller torque. By providing the first discharge chute 22, the second discharge chute 24, and the third discharge chute 25, this invention ensures that even when the distribution cylinder 2 is not full (e.g., half-full), its center of gravity remains close to the shaft 012, allowing the first motor 3 to rotate the distribution cylinder 2 with a smaller torque.

[0020] In another embodiment of the present invention: the fabric hopper 1 is provided with a sealing mechanism 4 below its inlet 11, and a sealing airbag 5 is provided above its inlet 11, with the sealing airbag 5 located on the outer edge of the inlet 11. When the feeding device lowers its cover 400 to the inlet 11, the sealing airbag 5 inflates to seal the feeding device and the fabric hopper 1, preventing dust from escaping between them. After the feeding device finishes feeding, the sealing mechanism 4 closes the inlet 11 to prevent dust from escaping. With this structural design, even if some material falls onto the sealing airbag 5, it will not affect the sealing between the feeding device and the fabric hopper 1. Other sealing devices, if they have material adhering to them, are easily affected in terms of sealing performance or are easily damaged by the material. Secondly, the fabric bin 1 is sealed by the sealing airbag 5 and the sealing mechanism 4, eliminating the need to design a door for sealing. The doorless design solves two problems: first, the problem of material jamming in conventional electro-hydraulic actuator arc doors when processing blocky mixed materials (regardless of the size of the gap); and second, the problem of high failure rate of electro-hydraulic actuators.

[0021] As another embodiment of the present invention: refer to the appendix Figure 4 The fabric hopper 1 has a sealing cover 6 below its discharge port 12. A support frame 7 is fixed to the bottom of the sealing cover 6, and the support frame 7 is connected to the lifting mechanism 8 of the fabric hopper 1. The sealing cover 6 is made of canvas. When the lifting mechanism 8 lifts the support frame 7, it lifts the sealing cover 6 upward, thus moving the sealing cover 6 away from the ground or the top of the hopper. When the fabric trolley needs to lay fabric, the lifting mechanism 8 lowers the support frame 7. The support frame 7, by its own weight, adheres tightly to the top of the hopper, preventing dust from escaping between the top of the hopper and the support frame 7 during fabric laying.

[0022] Specifically, the support frame 7 is wrapped with a rubber ring, which seals the top of the hopper, resulting in a better sealing effect.

[0023] Furthermore, the sealing cover 6 is fixed with multiple support frames 7 from top to bottom, with rubber rings wrapped around the bottom support frame 7. Through this structural design, when the lifting mechanism 8 lifts the support frame 7, it causes the sealing cover 6 to fold up. The folding structure design prevents the sealing cover 6 from being flattened during air intake, thus avoiding damage to the fabric.

[0024] In another embodiment of the present invention: a hinge shaft 81 is rotatably mounted at the bottom of the fabric bin 1. The hinge shaft 81 is fixed to a damper 82, which is used to close the discharge port 12. Lifting rods 83 are fixed to both ends of the hinge shaft 81. The lifting rods 83 are fixed to the support frame 7 via ropes 84. A third motor is connected to the hinge shaft 81. The rotation of the third motor drives the hinge shaft 81 to rotate, which in turn drives the damper 82 to rotate, thereby closing and opening the discharge port 12. When the hinge shaft 81 rotates and drives the damper 82 to rotate, it also drives the lifting rods 83 to rotate synchronously. Specifically, the damper 82 swings downward to open the discharge port 12, and the lifting rods 83 swing downward to lower the support frame 7 and seal the top of the bin. In this structural design, the ropes 84 and the lifting rods 83 constitute a lifting mechanism 8. The lifting mechanism 8 lifts the support frame 7 by means of the rotation of the hinge shaft 81, and the support frame 7 uses its own weight to drive the sealing cover 6 to unfold.

[0025] One embodiment of the sealing mechanism 4: Refer to the attached document. Figure 6 and attached Figure 7 The sealing mechanism 4 includes a sealing belt 41 and two rollers 42. The sealing belt 41 is fitted onto the two rollers 42, and the rollers 42 are connected to a second motor. The sealing belt 41 has a clearance hole 411 that matches the feed inlet 11. When the feeding device needs to discharge material, the second motor drives the rollers 42 to rotate, which in turn drives the sealing belt 41 to rotate, causing the clearance hole 411 to move below the feed inlet 11. The material coming out of the feeding device falls into the material distribution cylinder 2 through the feed inlet 11 and the clearance hole 411. When the feeding device finishes discharging material, the second motor drives the rollers 42 to rotate, which in turn drives the sealing belt 41 to rotate, causing the clearance hole 411 to move away from the feed inlet 11, and the sealing belt 41 closes the feed inlet 11 again. This structural design allows for quick closure of the feed inlet 11 and avoids interference with the sealing airbag 5.

[0026] In another embodiment of the present invention: a surrounding plate 43 is provided at the feed inlet 11, the surrounding plate 43 is located between two rollers 42, and the surrounding plate 43 is located inside the sealing belt 41. Sealing rings 44 are provided above and below the surrounding plate 43, and the sealing rings 44 are in contact with the sealing belt 41. The sealing rings 44 are provided to seal the gap between the surrounding plate 43 and the sealing belt 41, preventing dust from entering between the surrounding plate 43 and the rollers 42.

[0027] In another embodiment of the present invention: a first mounting groove 200 is provided above the fabric bin 1, and the sealing airbag 5 is located in the first mounting groove 200.

[0028] As another embodiment of the present invention: This embodiment also includes a support frame 10, and a weighing sensor 011 is provided between the material bin 1 and the support frame 10. The weighing sensor 011 obtains the weight information of the material in the material bin 2 so as to accurately distribute the material. For example, when receiving material, the weighing is used to determine whether the material bin 2 is full, and when discharging material, it is determined whether the unloading reaches the empty zero zone.

[0029] In another embodiment of the present invention, a material discharge channel 26 is formed between the first material discharge trough 22 and the material discharge plate 23, and the sum of the widths of the two material discharge channels 26 is less than or equal to the width of the first material discharge trough 22. This structural design ensures that the amount of material falling into the first material discharge trough 22 is no less than the amount of material falling into the third material discharge trough 25.

[0030] In another embodiment of the present invention, the material drop plate 23 is inclined, with the higher end of the material drop plate 23 close to the first material drop trough 22. This structural design allows as much material as possible to fall into both sides of the material distribution cylinder 2. Furthermore, when the material distribution cylinder 2 is distributing material, the material in the third material drop trough 25 can slide out along the inclined material drop plate 23, avoiding dead corners.

[0031] As another embodiment of the present invention: the first material discharge trough 22 includes two material distribution plates 221. The lower ends of the two material distribution plates 221 are fixed on the shaft 012 inside the material distribution cylinder 2. The two material distribution plates 221 are distributed in a V-shape. When the material distribution cylinder 2 is distributing material, the material of the third material discharge trough 25 can go out along the material distribution plates 221 to avoid dead corners.

[0032] In another embodiment of the present invention, a hopper 13 is provided at the lower end of the fabric bin 1, and the inner contour of the hopper 13 gradually decreases from top to bottom. If the material in the fabric cylinder 2 falls into the hopper 13, it can easily slide down to the discharge port 12.

[0033] In another embodiment of the present invention, the bottom of the support frame 10 is rotatably provided with traveling wheels 013 and guide wheels 014, which roll along the guide rail 015. The material placing trolley moves on the guide rail 015 via the traveling wheels 013 and guide wheels 014, thereby facilitating the material placing in each furnace top bin.

[0034] In another embodiment of the present invention: the suction port 100 is connected to the suction mechanism 9, which is located behind the support frame 10. The bottom wheels 013 of the suction mechanism 9 roll along the guide rail 015. Specifically, the suction mechanism 9 is hinged to the support frame 10. The suction mechanism 9 requires frequent cleaning, and this structural design facilitates the removal of the suction mechanism 9 from the support frame 10 for maintenance.

[0035] One implementation method for feeding the fabric carrier: The fabric carrier automatically travels to the material receiving position of the feeding equipment according to the positioning. At this time, the damper 82 has completed unloading and is in the closed state. Then, the rotating sealing belt 41 opens the upper feed port 11. After the sealing airbag 5 is inflated, it fits tightly against the cover 400 of the feeding equipment to achieve a seal. The feeding equipment is started to begin loading, and the dust collection mechanism 9 is turned on at the same time. According to the weighing signal of the fabric carrier, the system automatically controls the fast and slow feeding speeds. When the set advance amount is reached, the slow feeding stops, and the residual dust is continued to be collected for a period of time. Finally, the rotating sealing belt 41 closes the feed port 11, and the sealing airbag 5 retracts by blowing air in the reverse direction and disengages from the cover 400 of the feeding equipment. At this point, the entire dust-free quantitative loading process is completed.

[0036] One method for installing fabric on a fabric carrier: The fabric carrier travels to the designated unloading bin, opens the damper 82, and simultaneously lowers the sealing cover 6, which, under its own weight, tightly seals against the flange above the unloading bin. The dust extraction mechanism 9 is activated, and the fabric cylinder 2 is slowly rotated so that its fabric inlet 21 faces downwards. After determining from the weighing signal that the fabric carrier is completely empty, it pauses briefly to remove any remaining dust from the bin. Then, the damper 82 is closed, and the sealing cover 6 is retracted. The unloading process is now complete, and the fabric carrier can proceed to the next receiving bin.

[0037] In this invention, the fabric trolley moves to the feeding device, which lowers its cover 400 to adhere to the sealing airbag 5. The sealing airbag 5 inflates and seals the feeding device and the fabric bin 1. The sealing belt 41 rotates, causing the clearance hole 411 to move below the inlet 11. The damper 82 closes, and the material in the feeding device enters the fabric cylinder 2 along the inlet 11, clearance hole 411, and fabric outlet 21. The material first falls into the first discharge trough 22 and the third discharge trough 25 to ensure that even when the fabric cylinder 2 is only filled with a small amount of material, its center of gravity is close to the shaft 012. After the first discharge trough 22 is filled, the material falling on the first discharge trough 22 rolls along the accumulated material on the first discharge trough 22 into the second discharge troughs 24 on both sides to rebalance the material in the fabric cylinder 2, thereby bringing the center of gravity of the fabric cylinder 2 closer to the shaft 012. When the fabric cylinder 2 is full of material, its center of gravity is close to the shaft 012. With this structural design, the material filling cylinder 2 can be adjusted in terms of quantity, and the center of gravity of the material filling cylinder 2 is relatively close to the shaft 012. When material needs to be laid, the first motor 3 can drive the material filling cylinder 2 to rotate with a small torque so that the material opening 21 faces downward. When the feeding equipment discharges material, the sealing belt 41 opens the feed inlet, the damper 82 closes, and the feed inlet 11 and the material distribution inlet 21 are filled with dust. The dust around the feed inlet 11 enters the dust collection mechanism 9 through the second channel 300 and is discharged. When the feeding equipment finishes discharging material, the sealing belt 41 rotates to move the clearance hole 411 away from the feed inlet 11, thereby closing the feed inlet 11 again. When the material distribution trolley moves to the material distribution point to discharge material, the material distribution cylinder 2 rotates to make the material distribution inlet 21 face downward, the damper 82 opens, the sealing cover 6 unfolds downward, and the support frame 7 presses against the furnace top bin for sealing. When the material distribution cylinder 2 discharges material into the furnace top bin, the space between the material distribution inlet 21 and the furnace top bin is filled with dust. The dust around the material distribution inlet 21 enters the dust collection mechanism 9 through the second channel 300 and is discharged. During the movement of the material distribution trolley, if there is dust, the dust collection mechanism 9 sucks away the dust in the material distribution bin 1 and the material distribution cylinder 2 through the second pipe. Through this structural design, the material feeding trolley can suck up dust during feeding, unloading, and movement, eliminating the possibility of material clogging the air intake during feeding and unloading, resulting in excellent dust collection. Furthermore, the dust collection mechanism 9 can also suck up dust from the head of the feeding equipment and the furnace top chamber.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
