Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 The utility model provides a technical solution: a conveyor with an extended structure, comprising: a base 1 and a transmission belt 9, a frame 2 is installed on the top of the base 1, a driving motor 3 is installed on one side of the frame 2, a first positioning roller 4 is installed on one side of the driving motor 3, a second positioning roller 5 is arranged on the top of the first positioning roller 4, a first sliding roller 6 is arranged on one side of the second positioning roller 5, a second sliding roller 7 is installed on one side of the first sliding roller 6, a third positioning roller 8 is arranged on one side of the second sliding roller 7, and the transmission belt 9 is installed between the first positioning roller 4, the second positioning roller 5, the first sliding roller 6, the second sliding roller 7 and the third positioning roller 8.

[0022] The bottom of the first sliding roller 6 and the second sliding roller 7 are connected to a movable frame 10 through bearings, and a connecting rod 11 penetrating the base 1 is installed at the bottom of the movable frame 10. A screw sleeve 12 is connected between the two groups of connecting rods 11. A screw rod 13 is penetrated and connected in the middle of the screw sleeve 12. One end of the screw rod 13 is connected to a bevel gear set 14. The top of the bevel gear set 14 is connected to a transmission motor 15 penetrating the base 1 through an output shaft. The connecting rod 11 forms a threaded sliding structure through the screw sleeve 12 and the screw rod 13.

[0023] In specific implementation, when the conveyor with an extended structure is in use, the transmission motor 15 can be started according to the use requirements. The transmission motor 15 will drive the bevel gear set 14 to rotate through the output shaft at the bottom. The bevel gear set 14 is connected by two bevel gears that mesh with each other, one of which is connected to the output shaft of the transmission motor 15, and the other is connected to the screw rod 13. At this time, the bevel gear set 14 will drive the screw rod 13 to rotate. The outer side of the screw rod 13 is sleeved with a screw sleeve 12, and the two sides of the screw sleeve 12 are connected to the connecting rod 11. At this time, the screw rod 13 drives the screw sleeve 12 to slide, which will make the connecting rod 1 1 moves, and the top of the connecting rod 11 is connected with a movable frame 10 that penetrates the base 1, and the two sets of movable frames 10 are connected to the first sliding roller 6 through the bearing. The movement of the connecting rod 11 will drive the first sliding roller 6 to slide through the movable frame 10, and the second sliding roller 7 will also slide. Since the position of the first positioning roller 4 remains unchanged, the first sliding roller 6 and the second sliding roller 7 slide at this time, which will drive the entire transmission belt 9 to retract, so that the entire transmission belt 9 has an extension effect, which is convenient for adjusting the conveying length of the transmission belt 9 to meet the different usage requirements of users.

[0024] See also Figure 1 , Figure 2 and Figure 3 It can be seen that when in use, the transmission motor 15 can be started according to the use requirements. With the cooperation of the screw rod 13 and the screw sleeve 12, the movable frame 10 drives the first sliding roller 6 and the second sliding roller 7 to move. At this time, the length of the transmission belt 9 can be adjusted so that the transmission belt 9 has an extension effect.

[0025] A top frame 16 is installed on the top of the frame 2, a water tank 17 is installed on the top of the top frame 16, a water pump 18 is connected to the top of the water tank 17 through a water pipe, a hose 19 is connected to one side of the water pump 18, an atomizing nozzle 20 is installed on the side of the hose 19 away from the water pump 18, the top of the atomizing nozzle 20 is connected to a fixed frame 21 through a rotating shaft, a connecting rod 22 is connected to one side of the atomizing nozzle 20 through a rotating shaft, a threaded sleeve 23 is connected to the side of the connecting rod 22 away from the atomizing nozzle 20 through the rotating shaft, a screw 24 is connected through the middle of the threaded sleeve 23, a servo motor 25 is connected to the bottom of the screw 24, and the atomizing nozzle 20 forms a rotating structure with the fixed frame 21 through the rotating shaft.

[0026] In specific implementation, the conveyor with an extended structure can start the water pump 18 according to the use requirements when in use, so that the water pump 18 can drain the water in the water tank 17 to the position of the water pump 18 through the pipeline, and then spray the water out through the cooperation of the water pump 18 and the hose 19. At the same time, the servo motor 25 can be started, and the servo motor 25 will drive the top screw 24 to rotate. A threaded sleeve 23 is sleeved on the outer side of the screw 24. At this time, the screw 24 will drive the threaded sleeve 23 to slide, and a rotating shaft and a connecting rod 22 are connected on one side of the threaded sleeve 23. At this time, the threaded sleeve 23 will drive the connecting rod 22 to rotate. At the same time, the connecting rod 22 will rotate by pulling the atomizing nozzle 20 while rotating, so that the atomizing nozzle 20 can rotate through the rotating shaft between the fixing frame 21, so that the spraying angle of the atomizing nozzle 20 can be adjusted. The water mist sprayed by the atomizing nozzle 20 can reduce dust on the coal on the conveyor, so as to prevent excessive dust from affecting the normal operation of the operator.

[0027] See also Figure 1 and Figure 4 It can be seen that when in use, water can be sprayed onto the coal through the cooperation of the water pump 18 and the hose 19 according to the use requirements, so as to play a role in reducing dust on the coal.

[0028] To sum up: when using the conveyor with an extension structure, the base 1 can be placed in a stable position, and then the drive motor 3 is started. The drive motor 3 will drive the first sliding roller 6 to rotate, and the first positioning roller 4, the second positioning roller 5, the first sliding roller 6, the second sliding roller 7 and the third positioning roller 8 are sleeved with a transmission belt 9 on the outer side. At this time, the transmission belt 9 can move normally, and the coal to be transported is placed on the transmission belt 9, and the coal can be transported through the transmission belt 9. At the same time, the entire frame 2 can ensure the stability of the entire conveyor. This is the use feature of the conveyor with an extension structure.
