[0038] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a loading vehicle for a loading system, and the loading vehicle includes a vehicle body 1 , a cover body 2 and a movable arm mechanism 3 .

[0039] Specifically, if Figure 3 As shown, the vehicle body 1 includes a first shell 11, and the interior of the first shell 11 is configured with a first cavity 12 of the vehicle body 1, and the first cavity 12 is used to accommodate materials. A first opening 111 is provided above the first shell 11 and is connected to the first cavity 12, so that the material can enter the first cavity 12 from the first opening 111. The front side of the first shell 11 is provided with wheels 14, and the vehicle body 1 can move on the loading track 5 of the loading system through the wheels 14.

[0040] Furthermore, the first shell 11 is provided with a second heat-insulating layer 13, which includes a fire-resistant fiber layer. Specifically, the second heat-insulating layer 13 can be provided on the inner side surface of the first shell 11, or on the outer side surface of the first shell 11, or can be embedded in the material of the first shell 11 to form a sandwich; in this embodiment, if Figure 3As shown, the second thermal insulation layer 13 is disposed on the inner side of the first shell 11. Through the above arrangement, the second thermal insulation layer 13 can form a good thermal insulation effect in the first cavity 12, thereby effectively reducing the heat loss of the high-temperature material in the first cavity 12, reducing the heat consumption of the subsequent process, and improving the waste heat recovery efficiency, thereby improving production efficiency and having significant economic benefits.

[0041] As you can understand, refractory fiber is a fibrous refractory material and a highly effective thermal insulator. The refractory fiber layer possesses excellent thermal insulation properties, effectively isolating the heat radiation from high-temperature materials, thereby reducing heat loss and improving energy efficiency. Furthermore, the refractory fiber layer maintains its stability in high-temperature environments and does not undergo physical or chemical changes due to excessive temperatures, ensuring the long-term effectiveness of the insulation layer.

[0042] Continue to refer Figure 1 and Figure 2 The cover 2 includes a second shell 21, which is hingedly connected to the first shell 11 through a movable arm mechanism 3. The second shell 21 can be covered at the first opening 111 to close the first opening 111. Figure 4 As shown, the interior of the second shell 21 is constructed with a second cavity 22 of the cover body 2, and the rear side of the second shell 21 is provided with a second opening 211 connected to the second cavity 22, and the second opening 211 can be adapted to the discharge port 41 of the feeding system, and the bottom of the second shell 21 is provided with a third opening 212 connected to the second cavity 22. When the second shell 21 covers the first opening 111, the second cavity 22 is connected to the first cavity 12 through the third opening 212 and the first opening 111.

[0043] Continue to refer Figure 1 and Figure 2 The first end of the movable arm mechanism 3 is hingedly connected to the first housing 11, the second end of the movable arm mechanism 3 is used to connect to the traction end of the hoist of the feeding system, and the portion of the movable arm mechanism 3 near its second end is fixedly connected to the second housing 21. When the second housing 21 covers the first opening 111, the first housing 11 can swing downward about the first end of the movable arm mechanism 3, thereby separating the second housing 21 from the first opening 111 and opening the first opening 111.

[0044] Specifically, the movable arm mechanism 3 includes a traction rod 31 and two connecting rods 32. The traction rod 31 is used to connect to the traction end of the hoist of the feeding system. The first ends of the two connecting rods 32 are respectively hinged to the left and right sides of the first shell 11. The second ends of the two connecting rods 32 are respectively connected to the left and right ends of the traction rod 31. The parts of the two connecting rods 32 close to their second ends are respectively fixedly connected to the left and right sides of the second shell 21. Figure 2As shown, when the second shell 21 covers the first opening 111, the first shell 11 can swing downward around the first ends of the two connecting rods 32, thereby separating the second shell 21 from the first opening 111 to open the first opening 111; when the first shell 11 swings downward to a certain angle, the entire first shell 11 tilts downward, and under the action of gravity, the material in the first shell 11 will be discharged from the first opening 111.

[0045] The embodiment of the present invention provides a cover body 2 that can be set on the first opening 111 of the vehicle body 1. When the cover body 2 covers the first opening 111, the cover body 2 can prevent the material from collapsing from the first opening 111 to the outside, and can prevent the dust generated during the material receiving process from overflowing to the outside, thereby reducing pollution to the environment; in addition, when the cover body 2 covers the first opening 111, the cover body 2 can block the first opening 111, thereby preventing rain and snow from directly contacting the material and preventing the material from being contaminated by rain and snow; furthermore, the cover body 2 of the present invention can prevent external airflow from directly contacting high-temperature material, thereby preventing the heat of the high-temperature material from being carried away by external airflow and causing heat loss.

[0046] Furthermore, the second shell 21 is provided with a first heat-insulating layer 23, which includes at least one of a refractory fiber layer, a rock wool layer, and a nano-coating. Specifically, the first heat-insulating layer 23 can be provided on the inner side surface of the second shell 21, or on the outer side surface of the second shell 21, or can be embedded in the material of the second shell 21 to form a sandwich; in this embodiment, if Figure 4 As shown, the first heat insulation layer 23 is provided on the inner side surface of the second shell 21. Through the above arrangement, the cover 2 can form a good heat insulation effect at the first opening 111, thereby effectively reducing the heat loss of high-temperature materials during the receiving, conveying and unloading processes, reducing the heat consumption of subsequent processes, improving the waste heat recovery efficiency, and thus improving production efficiency, with significant economic benefits.

[0047] Rockwool is a commonly used inorganic fiber material, primarily made from the fiberization of natural rock or slag. Rockwool layers have low thermal conductivity, effectively preventing heat transfer and providing excellent thermal insulation. Furthermore, rockwool itself is non-flammable, making it fireproof. Nanocoatings are insulating layers made from nanoscale materials with low thermal conductivity. They also have low thermal conductivity, effectively preventing heat transfer and providing excellent thermal insulation.

[0048] Furthermore, an outer frame 24 is provided on the outer side of the second housing 21. The outer frame 24 is made of plain carbon steel or heat-resistant steel. This arrangement strengthens the overall structural strength of the second housing 21, preventing deformation of the second housing 21 when exposed to heat or external pressure or load, thereby improving the overall durability of the second housing 21 and extending its service life.

[0049] Furthermore, an opening and closing mechanism 213 is provided on a side portion of the second housing 21 , and the opening and closing mechanism 213 is configured to open or close the second opening 211 .

[0050] In this embodiment, if Figure 4 and Figure 5 As shown, the opening and closing mechanism 213 includes a first baffle 2131 and a sliding mechanism 2132. A pulley is provided on the side of the first baffle 2131 facing the sliding mechanism 2132, and a first abutment portion 21311 is provided on the lower portion of the outer side surface of the first baffle 2131. The sliding mechanism 2132 is provided on the rear side of the second shell 21; specifically, the sliding mechanism 2132 is two slide rails, and the two slide rails are respectively provided on the left and right sides of the second opening 211. When the loading car is slidably provided on the loading track 5 of the loading system, the sliding mechanism 2132 is parallel to the loading track 5, and the first baffle 2131 is slidably provided on the sliding mechanism 2132 via the pulley, so that the first baffle 2131 can move back and forth on the sliding mechanism 2132 in the direction of opening the second opening 211 and in the direction of closing the second opening 211.

[0051] The first baffle 2131 can slide upward to open the second opening 211. When the second opening 211 is open, it can be adapted to communicate with the discharge port 41 of the loading system. At this time, the material can enter the first cavity 12 through the discharge port 41, the second opening 211, the third opening 212, and the first opening 111 in sequence. When the second opening 211 is open, the first baffle 2131 can slide downward to close the second opening 211. At this time, the first baffle 2131 seals the second opening 211, which can prevent the heat of the high-temperature material in the loading car from being lost through the second opening 211, further improving the thermal insulation effect of the loading car.

[0052] In some specific embodiments, the opening and closing mechanism 213 includes a second baffle, which is hinged to the upper edge of the second opening 211 so as to be able to swing back and forth around the upper edge of the second opening 211 .

[0053] The second baffle can swing inward around the upper edge of the second opening 211 to open the second opening 211. When the second opening 211 is open, it can be adapted to communicate with the discharge port 41 of the feeding system. At this time, the material can enter the first cavity 12 through the discharge port 41, the second opening 211, the third opening 212, and the first opening 111 in sequence. When the second opening 211 is open, the second baffle can swing outward around the upper edge of the second opening 211 to close the second opening 211. At this time, the second baffle seals the second opening 211, which can prevent the heat of the high-temperature material in the feeding car from dissipating through the second opening 211, further improving the insulation effect of the feeding car.

[0054] The embodiment of the present invention further provides a feeding system, which includes a hoist, a feeding track 5, a discharge mechanism, and a feeding car according to the present invention. The feeding car is slidably arranged on the feeding track 5, and the hoist is connected to the movable arm mechanism 3 through a traction rod 31. Under the traction action of the hoist, the feeding car can move upward along the feeding track 5.

[0055] like Figure 6 and Figure 7 As shown, the discharge mechanism includes a discharge pipe 4 having a discharge port 41 that can be adapted to the second opening 211 , and a matching portion 42 is provided on the outer side of the discharge pipe 4 near the discharge port 41 .

[0056] Continue to refer Figure 6 and Figure 7 In this embodiment, the opening and closing mechanism 213 includes a first baffle 2131 and a sliding mechanism 2132. A pulley is provided on the side of the first baffle 2131 facing the sliding mechanism 2132. The first baffle 2131 is slidably provided on the sliding mechanism 2132 via the pulley, so that the first baffle 2131 can reciprocate on the sliding mechanism 2132 in the direction of opening the second opening 211 and in the direction of closing the second opening 211. A first abutting portion 21311 corresponding to the matching portion 42 is provided at the lower portion of the outer side surface of the first baffle 2131. When the first abutting portion 21311 abuts against the matching portion 42, the first baffle 2131 can slide downward to close the second opening 211 during the upward movement of the loading carriage along the loading rail 5, and can also slide upward to open the second opening 211 during the downward movement of the loading carriage along the loading rail 5.

[0057] Specifically, when the discharge port 41 of the discharge pipe 4 is adapted to be connected with the second opening 211, the second opening 211 is in an open state, and the first abutment portion 21311 correspondingly abuts against the matching portion 42; if the loading cart moves upward along the loading track 5 at this time, the loading cart will gradually move away from the discharge pipe 4, and the first baffle 2131 will slide downward under the action of gravity until the second opening 211 is closed, and the first abutment portion 21311 is separated from the matching portion 42, and the discharge port 41 is separated from the second opening 211.

[0058] When the discharge port 41 of the discharge pipe 4 is separated from the second opening 211, the second opening 211 is in a closed state, and the first abutment portion 21311 is separated from the matching portion 42; if the loading cart moves downward along the loading track 5 at this time, the loading cart will gradually approach the discharge pipe 4, and when the first abutment portion 21311 correspondingly abuts against the matching portion 42, the first baffle 2131 will slide upward during the downward movement of the loading cart until the second opening 211 is opened so that the discharge port 41 and the second opening 211 are adapted to be connected.

[0059] In some specific embodiments, the opening and closing mechanism 213 includes a second baffle, which is hinged to the upper edge of the second opening 211 so as to be able to swing back and forth around the upper edge of the second opening 211. The outer side of the second baffle is provided with a second abutment portion corresponding to the mating portion 42. The discharge pipe 4 can open the second opening 211 through the mating portion 42 and the second abutment portion.

[0060] Specifically, when the discharge port 41 of the discharge pipe 4 is adapted to be connected with the second opening 211, the second opening 211 is in an open state, and the second abutment portion correspondingly abuts against the matching portion 42, so that the second baffle maintains an inwardly tilted state; if the loading cart is separated from the discharge pipe 4 at this time, during the process of separation of the loading cart and the discharge pipe 4, the second baffle will swing outward until the second opening 211 is closed, and the second abutment portion is separated from the matching portion 42, and the discharge port 41 is separated from the second opening 211.

[0061] When the discharge port 41 of the discharge pipe 4 is separated from the second opening 211, the second opening 211 is in a closed state, and the second abutment portion is separated from the matching portion 42; if the loading cart approaches the discharge pipe 4 at this time, and when the second abutment portion correspondingly abuts against the matching portion 42, the second baffle will swing inward during the process of the loading cart approaching the discharge pipe 4 until the second opening 211 is opened so that the discharge port 41 and the second opening 211 are adapted to be connected.

[0062] It can be understood that since the feeding system is equipped with the above-mentioned feeding car, it has all the technical effects of the above-mentioned feeding car, which will not be repeated here.
