Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The double-chamber structure of the present utility model includes a support leg 1, a lower-chamber component 2 and an upper-chamber component 3 arranged inside the support leg 1. The left and right opposite inner sides of the support leg 1 are respectively provided with first angle steels 8 at the upper and lower parts. The left and right sides of the lower-chamber component 2 are arranged on the first angle steels 8 at the lower part of the support leg.

The front and rear sides of the upper-chamber component 3 are respectively provided with second end plate components 5 for realizing sequential connection. The upper-chamber component 3 has an upper chamber 7 with openings at the front and rear sides, and a plurality of air holes are evenly opened at the top of the upper chamber 7.

[0025] Specifically, the lower-chamber component 2 includes a first arc-shaped air box plate 2-1, a first arc-shaped upper groove plate 2-2, and two Z-shaped parts 2-3. The two Z-shaped parts 2-3 are respectively arranged on the left and right sides at the top of the first arc-shaped air box plate 2-1. The left and right sides at the bottom of the first arc-shaped upper groove plate 2-2 are arranged on the tops of the Z-shaped parts 2-3. The first arc-shaped air box plate 2-1, the first arc-shaped upper groove plate 2-2, and the two L-shaped parts 2-3 together form the lower chamber 6 with openings at the front and rear sides. A plurality of air holes are opened on the first arc-shaped upper groove plate 2-2. The first end plate component 4 includes two first connecting plates 4-1 and a first arc-shaped plate 4-2 arranged between the two second connecting plates 4-1.

The lower-chamber component 2 is arranged on the first angle steels 8 at the lower part of the support leg through the second angle steels 9.

[0026] When applied to a conveyor, the air chamber is formed by sequentially connecting a number of double air chamber structures. To further ensure the sealing performance of the lower air chamber after docking, a first front support plate 2-4 is welded to one end of the bottom of the first arc-shaped upper groove plate 2-1. The left and right ends of the first front support plate 2-4 are welded and fixed to two Z-shaped members 2-3. The first front support plate 2-4 extends out of the first arc-shaped upper groove plate to form a first reserved docking area. When sequentially assembling multiple double air chamber structures, the first arc-shaped upper groove plate of an air chamber structure welded with the first front support plate is docked with the first arc-shaped upper groove plate of another air chamber structure without the welded first front support plate. The first reserved docking area is used to place the first arc-shaped upper groove plate without the welded first front support plate. When the double air chamber structures are located at both ends of the air chamber, the first front support plate may not be welded according to the situation.

[0027] Furthermore, to strengthen the strength of the first arc-shaped upper groove plate, first rib plates 2-5 are spacedly arranged at the bottom of the first arc-shaped upper groove plate 2-2. The left and right ends of the first rib plates 2-5 are welded and fixed to two Z-shaped members 2-3.

[0028] Meanwhile, second rib plates 2-6 are spacedly arranged on the outer side wall of the Z-shaped member-like 2-3, and the second rib plates 2-6 extend to the outer side wall of the first arc-shaped air box plate 2-1.

[0029] Specifically, the upper air chamber assembly 3 includes a second arc-shaped air box plate 3-1, a second arc-shaped upper groove plate 3-2, and two C-shaped member-like 3-3. The two C-shaped member-like 3-3 are respectively arranged on the left and right sides of the second arc-shaped air box plate 3-1. The left and right sides of the bottom of the second arc-shaped upper groove plate 3-2 are arranged on the tops of the C-shaped member-like 3-3. The second arc-shaped air box plate 3-1, the second arc-shaped upper groove plate 3-2, and the two C-shaped member-like 3-3 together form an upper air chamber 7 with front and rear openings. A number of air holes are opened on the second arc-shaped upper groove plate 3-2. The second end plate assembly 5 includes two second connecting plates 5-1 and a second arc-shaped plate 5-2. The two second connecting plates 5-1 are respectively located on the outer sides of the front ends or rear ends of the two C-shaped member-like 3-3.

The upper air chamber assembly 3 is arranged on the first angle steel 8 on the upper part of the support leg through the third angle steels 10.

[0030] To further ensure the airtightness of the upper air chamber after docking, a second front support plate 3-4 is provided at one end of the bottom of the second arc-shaped upper groove plate 3-2. The second front support plate 3-4 extends out of the second arc-shaped upper groove plate to form a second reserved docking area. When sequentially assembling multiple double air chamber structures, the second arc-shaped upper groove plate of one air chamber structure welded with the second front support plate is docked with the second arc-shaped upper groove plate of another air chamber structure without the second front support plate welded. The second reserved docking area is used to place the second arc-shaped upper groove plate without the second front support plate welded. When the double air chamber structures are located at both ends of the air chamber, the second front support plate may not be welded according to the situation.

[0031] Furthermore, to strengthen the strength of the second arc-shaped upper groove plate, third rib plates 3-5 are arranged at intervals on the outer side of the second arc-shaped upper groove plate 3-2. The left and right ends of the third rib plates 3-5 are welded and fixed to two C-shaped parts 3-3.

[0032] Since the conveyor belt supports the material and walks on the top of the upper air chamber, the air pressure inside the upper air chamber is relatively large. To increase the strength of the upper air chamber assembly, steel plates 11 are arranged at intervals on the left and right sides of the top of the second arc-shaped air chamber plate 3-1. A fourth rib plate 12 is arranged between the steel plates 11 and the third rib plates 3-5.

[0033] Meanwhile, fifth rib plates 3-6 are arranged at intervals on the upper part of the outer side walls of the two C-shaped parts, and the fifth rib plate 3-6 located in the middle extends to the lower part of the C-shaped part.

[0034] Considering a better dust-proof effect, a sealing cover 13 is provided on the upper air chamber assembly.

[0035] Meanwhile, side sealing plates 14 are provided on the left and right sides of the upper air chamber assembly 2 and the lower air chamber assembly 3. The side sealing plates 14 and the upper air chamber assembly 2 and the lower air chamber assembly 3 together form a dust-proof chamber with openings at the front and back sides. The front and back sides of the side sealing plates 14 have fourth end plates for sequential connection. Specifically, the upper end of the fourth end plate of the side sealing plate is fixed to the bottom of the C-shaped part, and the lower end of the second end plate of the side sealing plate is fixed to the outer side of the top of the Z-shaped part.

[0036] In addition, the present utility model also provides an air-cushion belt conveyor, which includes a plurality of double air chamber structures. The plurality of double air chamber structures are sequentially docked and interconnected to form a double air chamber. A first centrifugal fan and a second centrifugal fan are respectively arranged on the outer sides of the double air chamber. The first centrifugal fan is connected to the upper air chamber and conveys gas, and the second centrifugal fan is connected to the lower air chamber and conveys gas.

[0037] More specifically, an air cushion belt conveyor includes a tail frame and a head frame. An electric roller is arranged on the head frame, and a deflecting roller is arranged on the tail frame. A conveyor belt is wound around between the electric roller and the deflecting roller. It further includes a feeding housing and a number of double-chamber structures connected in sequence and in butt joint and communication, which are arranged between the tail frame and the head frame in sequence. A feeding port is provided at the top of the feeding housing. The number of double-chamber structures are connected to form a double chamber. The top of the upper chamber and the top of the lower chamber of the double chamber are respectively used to support the conveyor belt, and a first centrifugal fan and a second centrifugal fan are respectively arranged on the outside thereof. The first centrifugal fan is connected to the upper chamber and conveys gas, and the second centrifugal fan is connected to the lower chamber and conveys gas.

[0038] Furthermore, a tail guard is provided on the tail frame. Both ends of the feeding housing are respectively connected and communicated with the tail guard and the double chamber. A head guard and a head hopper are provided on the head frame. The head guard is connected and communicated with the double chamber. This design makes the entire air cushion belt conveyor a fully enclosed structure, basically solving the problem of dust emission.
