[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention adopts a curtain wall structure to seal the outer side wall of the trolley as a whole, reducing the air leakage at the connection of the trolley. The plate is sealed by elastic contact through a spring, which can not only reduce severe wear due to excessive contact force, but also avoid the problem of poor sealing effect due to wear, and solve the problem of reduced sealing effect due to wear. The plate is always attached to the outside of the trolley to seal the gap of the trolley. The sealing effect decays slowly during use and has a long service life. The curtain wall structure is composed of multiple plates, each of which can be replaced separately, with low cost and easy maintenance. In addition, the sealing at the bottom of the car further improves the sealing effect on both sides of the bottom of the trolley, thereby reducing the air intake of the side walls of the trolley, allowing heat to better sinter the ore and improving the sintering quality.

[0018] 2. The panels of the present invention cooperate with the mounting grooves through the connecting seats, and the panels are spliced ​​together to form a whole. The connecting seats and the panels are connected and cooperated with each other. The connecting seats at both ends are limited by positioning blocks to achieve the positioning of the entire curtain wall structure. The fixing is convenient, and the connecting seats and the mounting grooves are convenient for disassembly and replacement. Each panel is fixed by a separate connecting seat, which cooperates with each other without affecting each other, thereby achieving the advantages of overall sealing and separate disassembly and assembly, and reducing manufacturing and maintenance costs.

[0019] 3. The connecting plate of the present invention can seal between two curtain wall structures, and adopts a contact sealing method, and will not rigidly fix the curtain wall structure. The connecting plate adopts a spring pressing method, which not only ensures that the connecting plate and the pasting plate are tightly fitted, but also enables the connecting plate to move back and forth with the pasting plate to achieve dynamic sealing; the upper end of the connecting plate is fitted and sealed with the upper end of the pasting plate, and the lower end of the connecting plate is slidably sealed with the connecting wall, ensuring the sealing effect at the connection position of the curtain wall structure.

[0020] 4. The vehicle bottom seal of the present invention is sealed by pressing the top sealing plate against the sealing rod, and a spring is used to keep the top sealing plate against the bottom of the sealing rod at all times, so that the effect will not be affected by wear. The contact surface will be smoother due to wear, thereby improving the sealing effect. The top sealing plate is always in contact with the sealing rod, and can be replaced only when the top sealing plate is completely worn out or the elastic force of the fourth spring is too small, thereby improving the utilization rate of materials.

[0021] 5. The present invention applies grease between the side sealing plate and the sealing rod, which can isolate dust from entering between the top sealing plate and the sealing rod on the one hand, and reduce friction between the side sealing plate and the sealing rod on the other hand.

Figure 3 As shown, the sealing walls 3 are connected by connecting walls 4, and the inner wall of the sealing wall 3 is elastically connected with a plate 2 that fits the side wall of the trolley 1. The plate 2 is attached to the outer wall of the trolley 1 and exerts a certain pressure on the trolley 1. There are multiple plates 2, which are connected to each other to form a curtain wall structure. Sealing strips are arranged between the plates 2, and multiple plates 2 form a wall structure. The plates 2 are provided with a makeshift groove 201 that matches the trolley 1, and the inner wall of the connecting wall 4 is elastically connected with a connecting plate 401 connected to the plate 2. In order to reduce the length of the curtain wall structure composed of the plates 2, multiple curtain walls are arranged, and the connection between the two curtain walls is closed by the connecting plate 401, and the curtain walls are sealed by the connecting plate 401. Sealing rods 101 are arranged on both sides of the bottom of the trolley 1, and the sealing rods 101 are slidably matched with the bottom seal 7 of the vehicle to seal both sides of the bottom of the trolley 1.

[0038] Among them, Fig.11 As shown, the connection seat 6 includes a pull plate 601 that cooperates with the mounting groove 304. One side of the pull plate 601 is connected to a positioning plate 603 through a pull block 602. The positioning plate 603 is attached to the outer wall of the mounting rod 301. A support sleeve 604 is provided on the side wall of the positioning plate 603. Figure 5As shown, a first support column 202 is provided on the side wall of the sticking plate 2, which is slidably matched with a support sleeve 604. A first spring 203 is sleeved on the outer side of the first support column 202. One end of the first spring 203 is connected to the sticking plate 2, and the other end of the first spring 203 is connected to the positioning plate 603. The first spring 203 makes the sticking plate 2 tightly attached to the side wall of the trolley 1 and has a certain elasticity, thereby playing a good sealing role.

[0039] A hook groove 605 is provided on the side wall of the support sleeve 604, and a pull hook 204 cooperating with the hook groove 605 is provided on one side of the first support column 202. The pull hook 204 is used to limit the paste board 2 to prevent the support sleeve 604 from separating from the first support column 202, thereby improving the reliability of the use of the paste board 2.

[0040] As the trolley 1 moves, the friction between the trolley 1 and the plate 2 will make the plate 2 have a driving force to slide in the moving direction of the trolley 1. Therefore, the connecting seat 6 is blocked by the positioning block 5. In order to facilitate the disassembly and assembly of the positioning block 5, mounting blocks 303 connected to the ends of the sealing wall 3 are provided at both ends of the mounting rod 301. The mounting blocks 303 are provided with mounting holes 302, such as Figure 8-10 As shown, the positioning block 5 includes a buffer block 502 and an end cover 507.
