Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a mobile dust-controlled tubular chain conveyor. Background Technology

[0002] Currently, bulk material conveying operations in China generally use mobile belt conveyors in combination. However, conventional mobile belt conveyors have two main drawbacks: First, most of the conveyor belt is exposed, generating a large amount of dust during bulk material conveying and transfer, causing environmental pollution, affecting workers' occupational health, and potentially posing safety hazards such as dust explosions. Second, mobile belt conveyors are relatively large, and due to limitations in the conveying angle, achieving higher conveying heights requires a longer equipment length, making movement difficult, increasing worker workload, and resulting in low overall operational efficiency.

[0003] Chinese patent document CN 220617404 U discloses an environmentally friendly grain conveying tube chain machine, including a frame, a chute, and a discharge hopper. A conveying pipe is fixedly installed on the top of the frame, a conveying chain is installed inside the pipe, a feed hopper is located at the top of the pipe, and a discharge hopper is located at the bottom of the pipe. The chute is located inside the pipe and has a limiting mechanism inside to fix the discharge hopper. A discharge port is located at the bottom of the hopper. This invention solves the problem that when transporting grain, a large amount of dust accumulates inside the pipe, which falls out with the grain in the discharge hopper, causing dust to fly around. However, this equipment still has two problems: First, the conveying frame itself is a truss structure, which is heavy and inconvenient to move; second, the scraper used is a conventional disc scraper, which causes high resistance and is prone to clogging when conveying loose grain in the enclosed tube chain machine. Utility Model Content

[0004] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a mobile dust-controlling tubular chain conveyor. This conveyor does not require truss support, but is supported by two fixed rings on the outer periphery of the closed tube and a movable support at the bottom. It is lightweight and easy to move; moreover, the scraper resistance is low, the material conveying is smooth, and the dust prevention effect is good.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile dust-controlling tubular chain conveyor includes a head, a closed tube body, a tail, and a movable support. The closed tube body includes a carrying section and a return unloaded section. The head and tail are respectively equipped with a driving sprocket and a driven sprocket. The driving sprocket and the driven sprocket are connected for slurry making via a scraper chain. A transmission device is provided on the driving sprocket. The tail is equipped with a feed inlet. The lower part of the head is connected to a discharge outlet. A scraper is provided on the scraper chain. A notch is provided at the lower part of the scraper. The notch is arranged from top to bottom to form a first flow channel and a second flow channel that are connected sequentially. The inner diameter of the first flow channel first increases and then decreases, while the inner diameter of the second flow channel first remains unchanged and then increases.

[0007] Furthermore, the two ends of the load-bearing section and the return unloaded section are respectively enclosed and connected to the head and tail of the machine, and the outer periphery is fixed by a fixing ring, the bottom of which is fixedly connected to the movable support.

[0008] Furthermore, the load-bearing section and the return unloaded section are fixed together by a support plate.

[0009] Furthermore, the bottom inner diameter of the discharge port is smaller than the upper inner diameter.

[0010] Furthermore, the machine head and the discharge port form an angle of 150-160°.

[0011] The beneficial effects of this utility model are:

[0012] 1. This application discloses a mobile dust control tube chain conveyor, wherein the enclosed tube body includes a carrying section and a return empty section. The two ends of the carrying section and the return empty section are respectively enclosed and connected to the head and tail of the machine, and the middle is fixed by a fixed ring and a support plate. The bottom of the fixed ring is fixedly connected to the mobile bracket, which can achieve self-support, and the overall weight is light and convenient for manual movement.

[0013] 2. A notch is set at the bottom of the scraper, and flow channel one and flow channel two are arranged sequentially from top to bottom. The connection between flow channel one and flow channel two is relatively smooth. The inner diameter of flow channel one first increases and then decreases from top to bottom, while the inner diameter of flow channel two first remains unchanged and then increases. Therefore, during the high-speed movement of the scraper and under the action of gravity of the bulk material, the bulk material on the scraper undergoes a tumbling and rolling process, which can reduce the scraper jamming and blockage, and ensure the smooth operation of the tubular chain machine.

[0014] 3. The machine head and the discharge port are at an angle of 150-160°. The bulk grain is discharged in a swirling motion between the machine head and the discharge port. The inner diameter of the bottom of the discharge port is smaller than the inner diameter of the top. This causes the dust in the bulk grain to swirl at the machine head, making it easier for it to accumulate and settle, thus reducing dust flying when the material is discharged from the discharge port.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0021] like Figure 1-4 As shown, a mobile dust control tube chain conveyor includes a head 1, a closed tube body 2, a tail 3, and a mobile support 4. The closed tube body 2 includes a carrying section 21 and a return empty section 22. The two ends of the carrying section 21 and the return empty section 22 are respectively closed and connected to the head 1 and the tail 3, and are fixed by a fixing ring 9 on their outer periphery. The carrying section 21 and the return empty section 22 are fixed together by multiple support plates 10.

[0022] The bottom of the fixed ring 9 is fixedly connected to the movable bracket 4. The specific connection method is as follows: the movable bracket 4 consists of two V-shaped brackets. The two fixed rings 9 are welded to the tops of the two parallel V-shaped brackets at both ends. The bottoms of the two V-shaped brackets are welded through the crossbar 12. Wheels 11 are fixed on both sides of the end of the crossbar 12.

[0023] Since the load-bearing section 21 and the return unloaded section 22 are fixedly connected to the head 1 and tail 3 respectively, and the outer periphery is fixed by the fixing ring 9 and the inner periphery is fixed by the support plate 10, they can achieve self-support and do not require a truss; moreover, the bottom is fixedly connected to the movable support 4, and the overall weight is light, making it convenient for manual movement.

[0024] The head 1 and tail 3 are respectively equipped with a drive sprocket and a driven sprocket, which are connected by a scraper chain. A transmission device (drive motor) is installed on the drive sprocket. The rotation of the drive motor drives the drive sprocket to rotate, which in turn drives the scraper chain to move and the driven sprocket to rotate, thereby realizing the scraper transport of materials. The tail 3 is equipped with a feed inlet 5, and the lower part of the head 1 is connected to the discharge outlet 6. The head 1 and the discharge outlet 6 are at a 150-160° angle, which is 160° in this embodiment. When the transported bulk materials, such as grain, are discharged, an arc is formed between the head 1 and the discharge outlet 6. Since the inner diameter of the bottom of the discharge outlet 6 is smaller than the inner diameter of the top, the dust in the bulk grain will rotate at the head, thereby increasing the interaction of dust in the grain and making it easier to agglomerate into large particles before being discharged with the grain, reducing dust flying when the grain is discharged from the outlet.

[0025] Scraper 7 is provided on the scraper chain, and notch 8 is provided at the lower part of scraper 7, wherein the structure of notch 8 is as follows: Figure 3 As shown, the gap 8 is arranged from top to bottom with sequentially connected flow channels 1 81 and 2 82. The connection between flow channels 1 81 and 2 82 is an arc-shaped connection, which is relatively smooth. The inner diameter of flow channel 1 81 first increases and then decreases from top to bottom, while the inner diameter of flow channel 2 82 first remains unchanged and then increases. With this scraper design, in the process of transporting bulk materials such as bulk grain, the grain flowing through flow channel 1 has a large weight and the grain flowing through flow channel 2 has a small weight. During the high-speed movement of the scraper and under the action of the gravity of the grain, the grain transported on the scraper will undergo a tumbling and rolling process, thus playing a role in unblocking, reducing material jamming and ensuring the smooth operation of the tubular chain machine.

[0026] Finally, 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. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
