[0002] The conveyor belt used in a concrete mixing plant is an industrial conveying device, mainly used for transporting materials in the plant. A conveyor belt typically consists of two rectangular baffles, several rollers, and a flat belt. The rollers are spaced apart between the two baffles, and the flat belt is fitted over the rollers to form a closed loop, thus constituting a complete conveyor belt. The conveyor belt is generally driven by a motor.

[0003] According to Chinese Patent Publication No. CN210910629U, a liftable conveyor belt for a concrete mixing plant is disclosed. It includes a conveyor belt body, a lifting tower, and a lifting structure. The lifting tower includes a base and multiple support columns, all vertically mounted on the base. The lifting structure is rotatably connected to the conveyor belt body and moves along the support columns. This invention provides adjustable conveyor belt height. However, this conveyor belt has shortcomings. When material is discharged from the mixing equipment, it is directly impacted by the material, which can cause wear and even tearing of the conveyor belt surface, shortening its service life. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a conveyor belt for a mixing plant with a long service life. It solves the problem that when the material is discharged from the mixing equipment, the conveyor belt is directly impacted by the material. This impact force will cause wear or even tearing of the conveyor belt surface, thus shortening the service life of the conveyor belt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a long-service-life conveyor belt for a mixing plant, comprising a material conveyor belt and a leak-proof concentrating mechanism. An anti-impact protection mechanism is provided on the upper surface of the material conveyor belt, located below the mixing equipment. The anti-impact protection mechanism includes a support plate, connecting arms, connecting slide rails, an anti-impact discharge plate, dampers, and buffer springs. The material conveyor belt is positioned above a conveyor belt support. Two support plates are fixedly connected to both the left and right sides of the conveyor belt support. Connecting arms are fixedly connected to the upper surfaces of the four support plates. Connecting slide rails are fixedly connected to the inner sides of the four connecting arms. An anti-impact discharge plate is slidably connected between the four connecting slide rails. Dampers are provided at the four corners of the lower surface of the anti-impact discharge plate. The free ends of the dampers are fixedly connected to the anti-impact discharge plate. The fixed ends of the dampers are fixedly connected to the upper surface of the support plates. Buffer springs are sleeved on the outer sides of the free ends of the dampers.

[0006] Preferably, the leak-proof centralized mechanism includes a support crossarm, a side inclined plate, a fixed column, and a support inclined rod. The number of support crossarms is set to multiple, and the multiple support crossarms are evenly distributed on the upper surface of the conveyor belt support.

[0007] Preferably, each of the supporting crossarms is fixedly connected to a side inclined plate on both the left and right sides, and a supporting inclined rod is rotatably connected to the inner side of each of the left and right side inclined plates.

[0008] Preferably, the ends of the two supporting diagonal rods away from the side inclined plate are respectively rotatably connected to the left and right sides of the fixed column, and the lower end of the fixed column is fixedly connected to the middle position of the upper surface of the supporting cross arm.

[0011] Beneficial effects

[0012] This invention provides a conveyor belt for a mixing plant with a long service life. Compared with the prior art, it has the following advantages:

[0013] 1. In this utility model, the anti-impact protection mechanism is set up so that when the material is discharged from the mixing equipment of the mixing plant onto the conveyor belt, the anti-impact protection mechanism starts to play its role. When the material falls and impacts the anti-impact discharge plate, the damper and the buffer spring work together to absorb and disperse the impact force. The damper consumes the impact energy through the movement of its free end, while the buffer spring provides additional buffering effect, reducing the direct impact on the conveyor belt. Afterward, the mixed material that falls onto the anti-impact discharge plate slowly slides down the inclined surface of the anti-impact discharge plate onto the surface of the material conveyor belt, reducing the risk of wear and tear on the surface of the conveyor belt, thereby increasing the service life of the conveyor belt.

[0014] 2. In this utility model, through the setting of the anti-leakage concentration mechanism, after the mixed material is buffered by the anti-impact protection mechanism and falls onto the surface of the material conveyor belt, since the middle of the material conveyor belt is not supported by the two supporting diagonal rods, the middle of the material conveyor belt will be concave downward under the action of the gravity of the material, preventing some of the mixed material from falling from both sides of the material conveyor belt, reducing material loss and improving the utilization rate of the material.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides two technical solutions, specifically including the following embodiments:

[0023] Example 1:

[0024] A long-life conveyor belt for a mixing plant includes a material conveyor belt 1 and a leak-proof concentrating mechanism 3. An anti-impact protection mechanism 2 is installed on the upper surface of the material conveyor belt 1, positioned below a mixing device 4, which is a commonly used material mixing and blending device in mixing plants. The anti-impact protection mechanism 2 includes a support plate 201, connecting arms 202, connecting slide rails 203, an anti-impact discharge plate 204, a damper 205, and a buffer spring 206. The material conveyor belt 1 is positioned above a conveyor belt support 5. Two support plates 201 are fixedly connected to both the left and right sides of the conveyor belt support 5. Connecting arms 202 are fixedly connected to the upper surfaces of all four support plates 201. The two front connecting arms 202 are higher than the two rear connecting arms 202, providing anti-impact discharge protection. The material plate 204 is tilted from front to rear, and the surface of the anti-impact unloading plate 204 is smooth. The inner sides of the four connecting arms 202 are all fixedly connected to the connecting slide rails 203. The anti-impact unloading plate 204 is slidably connected in the middle of the four connecting slide rails 203. The four corners of the lower surface of the anti-impact unloading plate 204 are all provided with dampers 205. The free ends of the dampers 205 are all fixedly connected to the anti-impact unloading plate 204. The fixed ends of the dampers 205 are fixedly connected to the upper surface of the support plate 201. A buffer spring 206 is sleeved on the outer side of the free end of the damper 205. The upper end of the buffer spring 206 is fixedly connected to the lower surface of the anti-impact unloading plate 204, and the lower end of the buffer spring 206 is fixedly connected to the upper surface of the fixed end of the damper 205. The spring stiffness of the buffer spring 206 is 10N / mm.

[0025] During operation, when the material is mixed and discharged from the mixing equipment 4 of the mixing plant onto the conveyor belt, the anti-impact protection mechanism 2 begins to function. When the material falls and impacts the anti-impact discharge plate 204, the damper 205 and the buffer spring 206 work together to absorb and disperse the impact force. The damper 205 dissipates the impact energy through the movement of its free end, while the buffer spring 206 provides additional cushioning, reducing the direct impact on the conveyor belt. Afterward, the mixed material that falls onto the anti-impact discharge plate 204 slowly slides down the slope of the anti-impact discharge plate 204 onto the surface of the material conveyor belt 1, reducing the risk of wear and tear on the conveyor belt surface and thus increasing the service life of the conveyor belt.

[0026] Example 2:

[0027] Based on Embodiment 1, the leak-proof centralized mechanism 3 includes a supporting horizontal arm 301, side inclined plates 302, a fixed column 303, and supporting inclined rods 304. Multiple supporting horizontal arms 301 are equidistantly distributed on the upper surface of the conveyor belt support 5. Each supporting horizontal arm 301 has side inclined plates 302 fixedly connected to its left and right sides. Supporting inclined rods 304 are rotatably connected to the inner sides of both side inclined plates 302. The ends of the two supporting inclined rods 304 away from the side inclined plates 302 are rotatably connected to the left and right sides of the fixed column 303, respectively. The lower end of the fixed column 303 is fixedly connected to the middle position of the upper surface of the supporting horizontal arm 301. The material conveyor belt 1 is internally located at both ends of the material conveyor belt. A drive roller 6 is installed throughout the conveyor belt 1. The left and right ends of the drive roller 6 are rotatably connected to the inner sides of two roller fixing plates 8. The lower end of the roller fixing plate 8 is fixedly connected to the upper surface of the conveyor belt support 5. A motor 7 is installed on the outer side of the roller fixing plate 8. The output end of the motor 7 is connected to the drive roller 6. After the mixed material is buffered by the anti-impact protection mechanism 2 and falls onto the surface of the material conveyor belt 1, the middle of the material conveyor belt 1 is not supported by the two supporting diagonal rods 304. Therefore, under the action of gravity of the material, the middle of the material conveyor belt 1 is concave downward, preventing some of the mixed material from falling from the sides of the material conveyor belt 1, reducing material loss and improving material utilization.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
