Description

Technical Field

[0001] This utility model belongs to the field of material conveying equipment, specifically a low-noise material conveyor. Background Technology

[0002] A material conveyor is a device that continuously transports materials along a fixed line. Also known as a continuous conveyor, it can transport materials horizontally, inclined, and vertically, and can also form spatial conveying lines. The conveying line is generally fixed. It transmits traction force through traction components, supports materials through load-bearing components, provides power through a drive device, maintains the tension and sag of the traction components through a tensioning device, and supports the traction components or load-bearing components to achieve the conveying of materials. During operation, materials are continuously transported along a fixed line. The loading and unloading of the working components are carried out during the movement process, without the need to stop, and with less starting and braking. Belt conveyors are a commonly used type of material conveying equipment.

[0003] Belt conveyors are widely used material conveying equipment in industries such as mining, metallurgy, and coal. They have advantages such as large conveying capacity, simple structure, convenient maintenance, and standardized components. They can be used to convey loose materials or packaged goods. Belt conveyors mainly consist of a drive unit, conveyor belt, conveyor rollers, and idlers. The drive unit of a belt conveyor mainly consists of a drive motor and sprockets and chains. The drive motor drives the sprockets and chains to perform transmission, thereby enabling the conveyor belt to carry out the transmission operation. Over a long period of use, the sprockets and chains will experience wear and aging, resulting in increased operating noise. Moreover, the higher the operating speed of the sprockets and chains, the greater the noise.

[0004] In summary, this utility model provides a low-noise material conveyor to solve the above-mentioned problems. Utility Model Content

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a low-noise material conveyor, including a conveyor frame 1. A conveyor assembly 2 is installed on the top of the conveyor frame 1. The conveyor assembly 2 is used to convey materials. The conveyor assembly 2 includes a conveyor roller 201, an idler roller 202, a rubber pad 203, and a conveyor belt 204. A drive assembly 3 is installed on one side of the conveyor frame 1. The drive assembly 3 is used to drive the conveyor assembly 2. The drive assembly 3 includes a base 301, a protective cover 302, a drive motor 303, a worm gear reducer 304, a synchronous pulley 305, a synchronous belt 306, and a transmission rod 307. The number of conveyor rollers 201 is set to two, and the two conveyor rollers 201 are respectively installed on the conveyor frame 1. At the front and rear ends of the top, rubber pads 203 are fixed to the surface of conveyor rollers 201. Idler rollers 202 are located between the two conveyor rollers 201. Conveyor belts 204 are sleeved on the surfaces of idler rollers 202 and rubber pads 203. Synchronous pulleys 305, synchronous belts 306, and transmission rods 307 are all installed in the inner cavity of the protective cover 302. Drive motors 303 and worm gear reducers 304 are all installed on the top of the base 301. There are two synchronous pulleys 305, which are respectively installed at the upper and lower ends of the inner cavity of the protective cover 302. One end of the transmission rod 307 is fixedly connected to the upper synchronous pulley 305, and the other end of the transmission rod 307 extends through to the outside of the protective cover 302 and is connected to the front conveyor rollers 201.

[0024] like Figure 1-4As shown, the output shaft of the drive motor 303 rotates, which drives the lower synchronous pulley 305 to rotate via the worm gear reducer 304. When the lower synchronous pulley 305 rotates, it drives the upper synchronous pulley 305 to rotate via the synchronous belt 306. When the upper synchronous pulley 305 rotates, it drives the front conveyor roller 201 to rotate via the transmission rod 307. When the front conveyor roller 201 rotates, it drives the rear conveyor roller 201 to rotate via the conveyor belt 204, thus enabling the conveyor belt 204 to perform transmission operations. The idler roller 202 provides support for the conveyor belt 204 during transmission. The rubber pad 203 reduces friction between the conveyor belt 204 and the conveyor roller 201 and absorbs and reduces vibration, thus helping to reduce noise. By replacing the traditional sprocket and chain drive with the synchronous pulley 305 and synchronous belt 306, the transmission ratio is accurate, there is no slippage, a constant speed ratio can be obtained, transmission is smooth, noise is low, and the transmission ratio range is wide. This reduces the noise of the material conveyor during operation, enabling it to operate with low noise.

[0025] Example 2

[0026] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the synchronous belt 306 is sleeved on the surface of the two synchronous pulleys 305, the output shaft of the worm gear reducer 304 passes through the inner cavity of the protective cover 302 and is connected to the lower synchronous pulley 305 in a transmission connection, and the output shaft of the drive motor 303 is connected to the input shaft of the base 301 in a transmission connection.

[0028] The drive motor 303 and the worm gear reducer 304 are both fixed to the top of the base 301, and the protective cover 302 is fixedly connected to the conveyor frame 1.

[0029] The conveying assembly 2 also includes a support base 205 and a bracket 206. The bracket 206 is fixedly connected to the conveying frame 1. The idler roller 202 is installed in the inner cavity of the bracket 206 through a bearing. The surface of the rubber pad 203 is provided with anti-slip texture.

[0030] Support seats 205 are installed on both sides of the top front end and rear end of the conveyor frame 1. The front support seat 205 is fixedly connected to the conveyor frame 1, and the conveyor roller 201 is movably connected to the support seat 205 through bearings.

[0031] like Figure 1-4As shown, the anti-slip texture on the surface of the rubber pad 203 can increase the friction with the conveyor belt 204, thereby reducing slippage during the operation of the conveyor belt 204. The inner wall of the protective cover 302 can be bonded with sound-absorbing cotton to reduce the noise generated by the synchronous pulley 305 and the synchronous belt 306. The protective cover 302 can also provide protection for the synchronous pulley 305 and the synchronous belt 306, thereby reducing wear on the synchronous pulley 305 and the synchronous belt 306. The support seat 205 can provide support for the conveyor roller 201, and the bracket 206 is used to provide support for the idler roller 202, thereby enabling the conveyor belt 204 to operate stably.

[0032] Example 3

[0033] Reference Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] In this embodiment, adjustment components 4 are installed on both sides of the top rear end of the conveyor frame 1. The adjustment components 4 are used to adjust the rear conveyor roller 201. The adjustment components 4 include a chute 401, a threaded hole 402, a slider 403, a screw 404, and a knob 405.

[0035] The slide 401 is located on the top of the conveyor frame 1, the threaded hole 402 is located on the back of the conveyor frame 1, one end of the slider 403 is fixedly connected to the rear support 205, the other end of the rubber pad 203 extends into the inner cavity of the slide 401 and is slidably connected to the inner cavity of the slide 401, one end of the screw 404 is movably connected to the slider 403 through a bearing, the other end of the screw 404 passes through the threaded hole 402 and is threadedly connected to the inner cavity of the threaded hole 402, and the knob 405 is fixedly connected to the end of the screw 404 away from the slider 403.

[0036] like Figure 3 As shown, rotating the knob 405 clockwise causes the screw 404 to rotate along the inner cavity of the threaded hole 402 and move towards the inner cavity of the slide groove 401. When the screw 404 moves, it pushes the slider 403 forward. When the slider 403 moves, it drives the rear support 205 to move forward along the inner cavity of the slide groove 401, thereby adjusting the position of the rear conveyor roller 201. Rotating it counterclockwise adjusts the rear conveyor roller 201 backward, thereby adjusting the tension of the conveyor belt 204, ensuring the stability of the conveyor belt 204 during operation, and reducing slippage.

[0037] In operation, the output shaft of the drive motor 303 rotates, which in turn drives the lower synchronous pulley 305 to rotate via the worm gear reducer 304. The rotation of the lower synchronous pulley 305 drives the upper synchronous pulley 305 to rotate via the synchronous belt 306. The rotation of the upper synchronous pulley 305 then drives the front conveyor roller 201 to rotate via the transmission rod 307. The rotation of the front conveyor roller 201, in turn, drives the rear conveyor roller 201 to rotate via the conveyor belt 204, thus enabling the conveyor belt 204 to perform transport operations. The idler roller 202 provides support to the conveyor belt 204 during transport. The rubber pad 203 reduces friction between the conveyor belt 204 and the conveyor roller 201, and also absorbs and reduces vibration, thus helping to reduce noise. The synchronous pulley 305 and synchronous belt 306 replace the traditional sprocket and chain drive, which has the advantages of accurate transmission ratio, no slippage, constant speed ratio, smooth transmission, low noise and a wide transmission ratio range, thereby reducing the noise of the material conveyor during operation and enabling it to operate with low noise. During operation or assembly, the tension of the conveyor belt 204 can be adjusted in time by adjusting component 4, thereby ensuring stable transportation.
