[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] According to Figures 1-3As shown in the figure, a highly adjustable belt idler for mining includes a base 1 provided with support columns 2. A gear set is rotatably installed in each support column 2, and the two gear sets on both sides are fixedly installed together through a transmission shaft 7. This setting can ensure that the two support frames 5 can move up or down simultaneously, ensuring the stability of the device. A motor 6 is fixedly installed on one of the support columns 2, and the output shaft of the motor 6 is matched with the gear set. Here, the motor 6 is a forward and reverse motor capable of self-locking. This motor 6 is a prior art and will not be elaborated here. Each gear set meshes with the racks on both sides inside the support frame 5 that is slidably installed on the inner wall of the support column 2. The top of the support frame 5 is detachably installed with a roller 9.

[0021] The gear set is composed of a first gear 3 and a second gear 4 meshed horizontally side by side. The first gears 3 between the two support columns 2 are fixedly connected through a transmission shaft 7, and the second gear 4 is rotatably installed on the support column 2. The output shaft of the motor 6 is fixedly connected to the first gear 3. This setting can ensure that the motor 6 drives the first gear 3 to rotate.

[0022] A chute is provided in the support column 2, and the support frame 5 is slidably installed in the chute of the support column 2. This setting can increase the stability of the device and ensure the normal up and down movement of the support frame 5.

[0023] The support frame 5 is rectangular, the middle of the support frame 5 is hollow, racks are fixedly installed on both sides of the middle of the support frame 5, and the racks on both sides of the middle of the support frame 5 mesh with the first gear 3 and the second gear 4 respectively.

[0024] A side plate 8 is fixedly installed on each support frame 5. A fixed seat 10 is fixedly installed on the top of each side plate 8, a guide groove 12 is opened at the bottom of each side plate 8, a clamping seat 11 is slidably installed on each guide groove 12, a cam 13 is rotatably installed below the clamping seat 11. The cam 13 is in the shape of a water droplet, and the bottom of the cam 13 is rotatably connected to the side plate 8. This setting can ensure that the cam 13 rotates to control the up and down movement of the clamping seat 11. The cam 13 cooperates with the clamping seat 11, and a handle 14 is installed at the bottom of the cam 13. The two ends of the roller 9 are respectively rotatably installed between the clamping seats 11 and the fixed seats 10 of the two side plates 8.

[0025] Threaded holes are provided on both the cam 13 and the guide groove 12, and a fixing bolt 15 is sequentially screwed with the cam 13 and the guide groove 12. The cam 13 and the guide groove 12 are fixedly connected through the fixing bolt 15.

[0026] Working principle: Place both ends of the idler 9 between the clamping seats 11 on both sides and the fixed seat 10 respectively. Control the grip 14 to rotate the cam 13, so that the cam 13 pushes the clamping seat 11 to move upward. The clamping seat 11 and the fixed seat 10 install the idler 9, and screw on the fixing bolt 15 to ensure the stability of the device. When it is necessary to adjust the height of the idler 9, control the motor 6 to rotate, and the first gear 3 and the second gear 4 both start to rotate through the transmission of the transmission shaft 7. The first gear 3 cooperates with the second gear 4 to drive the racks on both sides inside the support frame 5, so that the support frame 5 moves up or down, thereby adjusting the height of the idler 9.
