The driven shaft 34 is mounted at the front end of the rack 1 and arranged in parallel with the driving shaft 33.

[0054] The driving wheels 311 are sleeved on the driving shaft 33 and rotate synchronously with the driving shaft 33. The driven wheels 312 are mounted on the driven shaft 34 and serve as driven supports. The two chains 32 are respectively sleeved between the corresponding driving wheels 311 and driven wheels 312 to form a double-side synchronous transmission path.

[0055] The explosion-proof chain conveyor 100 of the embodiment of the present application is provided with the driving shaft 33 and the driven shaft 34 at both ends of the frame 1, and is provided with the driving wheel 311 and the driven wheel 312 in pairs, so that the double-side chain 32 is synchronously driven, the force distribution of the conveying chain 21 is more uniform, the running jitter or uneven wear caused by the unilateral partial load is reduced, the goods are stably moved, the collision or friction between the goods and the conveying chain 21 is reduced, and the generation of sparks is reduced.

[0056] In some embodiments, the transmission assembly 3 comprises at least one auxiliary shaft 35 and at least one set of auxiliary wheels 36, the auxiliary shaft 35 is located between the driving shaft 33 and the driven shaft 34 and can rotate relative to the frame 1. Each set of auxiliary wheels 36 is installed on an auxiliary shaft 35.

[0057] In this embodiment, the auxiliary shaft 35 is arranged at the middle position between the driving shaft 33 and the driven shaft 34 and is rotatably installed on the frame 1 for supporting the middle span of the chain 32. Each set of auxiliary wheels 36 is installed on the auxiliary shaft 35 and is in meshing or rolling contact with the chain 32, which plays a role of tensioning and guiding or intermediate support, preventing the chain 32 from sagging or jumping due to too large span.

[0058] For example, each set of auxiliary wheels 36 comprises two wheels which are in meshing with the chain 32. Or each set of auxiliary wheels 36 comprises three wheels, the wheels located at both ends of the auxiliary shaft 35 are in meshing with the chain 32, and the wheel arranged at the middle of the auxiliary wheels 36 is in rolling contact with the explosion-proof chain plate 22.

[0059] The explosion-proof chain conveyor 100 of the embodiment of the present application can keep the chain 32 in a tensioned state during long-distance conveying, reduce vibration and relaxation during operation, and improve transmission stability by additionally arranging the auxiliary shaft 35 and the auxiliary wheel 36 to support the chain 32 in the middle.

[0060] In some embodiments, the explosion-proof chain conveyor 100 comprises a leg assembly 5, and the leg assembly 5 comprises a stand column 51, a second cross beam 52 and a footing 53.

[0061] A plurality of stand columns 51 are arranged in pairs along the length direction of the frame 1 and are fixedly connected with the frame 1.

[0062] The two ends of the second cross beam 52 are fixedly connected with the same pair of stand columns 51.

[0063] The footing 53 is arranged at the bottom of the stand column 51 and is movable relative to the stand column 51 along the height direction of the frame 1.

[0064] For the convenience of description, the front-rear direction is consistent with the length direction of the frame 1, and the up-down direction is consistent with the height direction of the frame 1 in the following description of the technical scheme of the present application.

[0065] In this embodiment, the support leg assembly 5 is used to support the entire rack 1. A plurality of pairs of columns 51 are arranged in the front-rear direction, and each pair of columns 51 is connected by a second cross beam 52 to enhance lateral stability. The foot 53 is installed at the bottom of the column 51 and can be adjusted in position relative to the column 51 in the up-down direction to adapt to different ground conditions.

[0066] The explosion-proof chain conveyor 100 of the embodiment of the present application can adjust the height of the rack 1 according to the flatness of the installation ground by cooperating the adjustable foot 53 with the column 51, so that the rack 1 maintains a horizontal posture, which is conducive to the smooth operation of the conveying chain 21, thereby achieving smooth conveying of goods.

[0067] In some embodiments, the support leg assembly 5 includes an adjusting bolt 54, one end of which is threadedly connected with the column 51, and the other end is fixedly connected with the foot 53. The height of the rack 1 can be adjusted by rotating the adjusting bolt 54.
