A through hole 67 is opened on the outer surfaces of the support tube A61 and the support rod A63, and a latch 68 is inserted into the inside of the through hole 67. By pushing the parallel frame 1, the moving wheel 65 can roll along the ground and the whole can be moved to any position. At the same time, when the overall height needs to be adjusted, the latch 68 is pulled out so that the support rod A63 can move along the support tube A61, thereby realizing height adjustment.

[0032] An inclined roller 13 and a straight roller 14 are provided on one side of the parallel frame 1. The inclined roller 13 is arranged above the straight roller 14. Upper connecting rods 15 are provided on both sides of the parallel frame 1. An expansion baffle 16 is provided at one end of the upper connecting rod 15. Two groups of the expansion baffles 16 are located on both sides of the conveyor belt 5, and one end of the expansion baffle 16 is in contact with the surface of the conveyor belt 5. The motor 4 is started, and the output end of the motor 4 drives the active roller 2 to rotate, thereby rotating the conveyor belt 5. During the rotation of the conveyor belt 5, the inclined roller 13 and the straight roller 14 are driven to rotate. Since the inclined roller 13 is arranged at an angle, the middle of the conveyor belt 5 will be concave downward to ensure stable transportation. At the same time, the expansion baffle 16 can also prevent the material on the conveyor belt 5 from falling.

[0033] Both sides of the parallel frame 1 are provided with transverse grooves, in which guide rods 11 and guide blocks 12 are arranged, the guide rods 11 are arranged through the guide blocks 12, both ends of the active roller 2 are inserted into the guide blocks 12, the output end of the motor 4 passes through the guide blocks 12 and is connected to the active roller 2, locking nuts are arranged on the outer surface of the guide rods 11, and the locking nuts are distributed on both sides of the guide blocks 12, and the guide blocks 12 can be moved on the guide rods 11 by adjusting the locking nuts, thereby changing the position of the active roller 2 and realizing the tightness adjustment of the conveyor belt 5.

[0034] The auxiliary support assembly 7 includes a mounting plate 71 arranged at the lower end of the parallel frame 1, a support rod B79 arranged at the lower end of the mounting plate 71, and a support tube B791 arranged on the outer surface of the support rod B79.

When it is necessary to transport goods horizontally, pull out the plug rod, pull out the support tube B791 from the support rod B79, keep the parallel frame 1 horizontal, and then insert the plug rod to complete the horizontal transportation.

[0035] A bottom groove 72 is provided on the lower bottom surface of the mounting plate 71, a bottom block 74 is provided in the bottom groove 72, a mounting strip 76 is provided on the outer surface of the bottom block 74, two groups of bottom grooves 72 are provided and are horizontally arranged, each group of the bottom grooves 72 is provided with two groups of bottom blocks 74, extension rods 73 are penetrated inside the two groups of the bottom blocks 74, and a locking buckle 75 is threadedly provided on the outer surface of the extension rod 73, and by screwing the locking buckle 75, the bottom block 74 can be moved along the bottom groove 72 and the extension rod 73, and then the distance between the two groups of mounting strips 76 can be adjusted, thereby changing the overall stability.

[0036] An installation groove is provided inside the installation strip 76, and side grooves 761 are provided on both sides of the installation strip 76.

The locking buckle 77 is located on both sides of the installation strip 76. By screwing the locking buckle 77, the inclined plate B78 can be moved in the installation groove and along the inclined plate A762. Since the inclined plate A762 and the inclined plate B78 are inclined, when the inclined plate B78 moves, the inclined plate B78 will move up and down slightly.

[0037] The support rod B79 is hinged to the inclined plate B78, and the support rod B79 matches the installation groove. When the auxiliary support component 7 is not needed, the support rod B79 is folded so that part of the support rod B79 is inserted into the installation groove.

[0038] Specifically, in the process of transporting goods from a low place to a high place, the support rod B79 is inserted into the installation groove. When the overall height needs to be adjusted, the pin 68 is pulled out so that the support rod A63 can move along the support tube A61, thereby realizing height adjustment. When transporting goods from one end to the other end, the support rod B79 is opened, the support tube B791 is pulled out from the support rod B79, and the parallel frame 1 is kept level with the ground, and then the insertion rod is inserted to complete horizontal transportation. By screwing the locking buckle 77, the inclined plate B78 can be moved in the installation groove and along the inclined plate A762. Since the inclined plate A762 and the inclined plate B78 are inclined, when the inclined plate B78 moves, the inclined plate B78 will move up and down slightly, thereby realizing fine-tuning of the height, further improving the overall stability during operation, and through the overall setting of the auxiliary support assembly 7, the overall structure can meet the requirements of transporting goods from low to high, and also meet the requirements of transporting goods at the same height horizontally, with relatively few limitations.

A transmission rod 84 is arranged inside the transmission roller 83, and both ends of the transmission rod 84 are rotatably connected with the side plate 82. Both ends of the transmission rod 84 are provided with a limit plate 85, and a transmission belt 86 is sleeved on the outer surface of the limit plate 85. A linkage rod 87 is arranged inside the X-plate 81, and one end of the linkage rod 87 is connected to the transmission belt 86. The outer surface of the transmission roller 83 contacts the surface of the conveyor belt 5. During the rotation of the conveyor belt 5, the transmission roller 83 will be driven to rotate, and the rotation of the transmission roller 83 will drive the transmission belt 86 to rotate, and the transmission belt 86 will drive the linkage rod 87 to rotate.

[0041] A cylinder 871 is arranged on the outer surface of the linkage rod 87, a trapezoidal block A872 is arranged on the outer surface of the cylinder 871, a top box 88 is arranged on the outer surface of the parallel frame 1, a trapezoidal block B881 is arranged inside the top box 88, the trapezoidal block B881 corresponds to the trapezoidal block A872, one end of the trapezoidal block B881 is in contact with the conveyor belt 5, when the linkage rod 87 is rotating, it will drive the cylinder 871 to rotate together, and the cylinder 871 will drive the trapezoidal block A872 to rotate, when the trapezoidal block A872 is rotating, one end of it will contact the trapezoidal block B881, so that the trapezoidal block B881 is pushed up, thereby completing the partial lifting of the conveyor belt 5 and promoting material discharge.

[0042] A gear lever 882 is provided on the outer surface of the trapezoidal block B881, and the gear lever 882 is located inside the top box 88.

An external discharge pipe 89 is provided on one side of the top box 88, and one end of the external discharge pipe 89 is connected to the airbag cushion 883, and the other end of the external discharge pipe 89 is opposite to the conveyor belt 5. Whenever the trapezoidal block B881 moves upward, the gear lever 882 squeezes the airbag cushion 883, so that the gas in the airbag cushion 883 enters the external discharge pipe 89 and is ejected from the pipe mouth of the external discharge pipe 89 to gasify the impurities on the surface of the conveyor belt 5.

[0043] Specifically, during the working process, as the conveyor belt 5 continuously rotates, the transmission roller 83 will be driven to rotate, thereby causing the transmission belt 86 to rotate, and then driving the linkage rod 87 to rotate. During the rotation of the linkage rod 87, the cylinder 871 will be driven to rotate together, and the cylinder 871 will drive the trapezoidal block A872 to rotate.
