[0032] Example 2:

[0033] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the rotating rod 205 is set horizontally, and the rotating rod 205 is provided with positive and negative threads.

[0035] By setting a rotating rod 205 with positive and negative threads, it is easy to drive the two side insertion rods 202 to move. Under the limiting action of the slider 206 and the sliding rod 207, the two side insertion rods 202 will move towards each other, thereby achieving the purpose of simultaneously driving one end of the two side insertion rods 202 to leave the slot 201.

[0036] Specifically, a plug rod 202 is threaded onto the rotating rod 205. One end of the plug rod 202 penetrates the inner wall of the sliding sleeve 500. The plug rod 202 is cylindrical in shape.

[0037] The insertion rod 202 is designed to be inserted into the slot 201 under the drive of the rotating rod 205, thereby fixing the sliding sleeve 500 to the mounting rail 400 and facilitating the installation of the belt scale.

[0038] Specifically, the mounting rail 400 has a slot 201, the inner wall size of which is adapted to the size of the insertion rod 202.

[0039] The slot 201 is cylindrical in shape. The slot 201 is designed to receive the insertion of the plug rod 202, thereby enabling the belt scale to be installed and fixed.

[0040] Specifically, a gear ring 204 is fixedly installed on the rotating rod 205. The gear ring 204 is vertically set. A motor 208 is fixedly installed at the bottom end of the receiving plate 600. The motor 208 is horizontally set. A gear 209 is fixedly installed at the rotating shaft end of the motor 208. The gear 209 is vertically set and meshes with the gear ring 204.

[0041] The gear ring 204 is designed to mesh with the gear 209. The motor 208 is designed to drive the gear 209 to rotate. The motor 208 has forward and reverse rotation functions. The gear 209 is designed to mesh with the gear ring 204. By setting up the gear 209 and the gear ring 204, when the motor 208 is working, it serves to drive the rotating rod 205 to rotate.

[0042] Specifically, a slide rod 207 is fixedly installed on the side of the mounting base 203. The slide rod 207 is horizontally set, and a slider 206 is slidably set on the slide rod 207. The slider 206 is fixedly connected to one end of the insertion rod 202.

[0043] The slider 207 is designed to support the sliding of the slider 206. The slider 206 is designed to slide on the slider 207. By setting the slider 206 and the slider 207, the movement of the insertion rod 202 is limited, which facilitates the linear movement of the insertion rod 202.

[0044] Example 3:

[0045] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, a first mounting bracket 305 and a second mounting bracket 304 are fixedly installed at the top of the truss 301, and a side support roller is rotatably connected between the first mounting bracket 305 and the second mounting bracket 304.

[0047] The first mounting bracket 305 and the second mounting bracket 304 are provided for receiving the side roller and the first shaft 306.

[0048] Specifically, a first shaft 306 is rotatably connected to the second mounting bracket 304, and a bottom support roller is fixedly mounted on the first shaft 306. The bottom support roller is set horizontally.

[0049] The first shaft 306 is cylindrical in shape and is horizontally positioned. The first shaft 306 is used to support the installation of the bottom roller.

[0050] Specifically, a vertical plate 310 is fixedly installed on the inner wall of the truss 301. The vertical plate 310 is vertically set, and a second shaft 308 is rotatably connected to the vertical plate 310. The second shaft 308 is connected to the first shaft 306 through the track mechanism 307.

[0051] The vertical plate 310 is used to support the installation of the second shaft 308, and the second shaft 308 is used to support the installation of the blade 309. The track mechanism 307 includes a first transmission wheel, a second transmission wheel, and a track. The first transmission wheel is fixedly installed on the first shaft 306, and the second transmission wheel is fixedly installed on the second shaft 308. The track is engaged with the first transmission wheel and the second transmission wheel. By providing the track mechanism 307, when the first shaft 306 rotates, it drives the second shaft 308 to rotate.

[0052] Specifically, the second shaft 308 is cylindrical in shape, horizontally positioned, and a blade 309 is fixedly installed at one end of the second shaft 308.

[0053] The second shaft 308 is designed to support the installation of the blade 309. The blade 309 facilitates the cooling of the load cell 302 by blowing air through it, which is beneficial for the long-term use of the load cell 302.

[0054] When the belt scale is in use, the belt will drive on the side rollers and bottom rollers. When the belt is driving, it will transport the material. The weight of the material is transmitted to the truss 301 through the belt, side rollers, bottom rollers, first mounting frame 305 and second mounting frame 304, and then transmitted by the truss 301 to the weighing sensor 302. The weighing sensor 302 is a known technology, and its principle will not be described in detail.

[0055] Furthermore, during the belt drive process, the belt will drive the measuring roller and the bottom roller to rotate. When the bottom roller rotates, it will drive the first shaft 306 to rotate. When the first shaft 306 rotates, it will drive the second shaft 308 to rotate through the crawler mechanism 307. When the second shaft 308 rotates, it will drive the blade 309 to rotate. When the blade 309 rotates, it will generate natural wind and blow the wind towards the load cell 302, thereby achieving heat dissipation of the load cell 302 and facilitating its long-term use.

[0056] When it is necessary to disassemble the belt scale, start the motor 208. The motor 208 will drive the rotating rod 205 to rotate through the gear 209 and the gear ring 204. The rotating rod 205 is provided with positive and negative threads, which will drive the two side insert rods 202 to move. Under the limiting action of the slider 206 and the slide rod 207, the two side insert rods 202 will move towards each other until one end of the two side insert rods 202 leaves the slot 201. At this time, the fixing of the sliding sleeve 500 can be released, thereby realizing the purpose of disassembling the belt scale. In addition, by providing multiple sets of slots 201, the belt scale can be installed in different positions according to the actual use, which is beneficial to the use of the belt scale.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
