Description

Technical Field

[0001] This utility model relates to the field of sand and gravel transportation, and more specifically, to a dispersing mechanism for a sand and gravel belt conveyor and a conveyor having the dispersing mechanism. Background Technology

[0002] Sand and gravel are widely used as essential raw materials for construction, roads, and infrastructure. In mining companies, raw ore undergoes coarse crushing, fine crushing, and shaping processes after being mined, before being transported to warehouses or buffer depots by belt conveyors. After crushing, the sand and gravel particles are relatively fine, approximately 0.075-5mm. During the crushing process, water is often sprayed into the sand and gravel to prevent dust contamination; this process is called "wet sand making." However, wet sand making can lead to the sand and gravel agglomerating, which negatively impacts subsequent transportation and storage. Utility Model Content

[0003] The purpose of this application is to solve the problem of sand and gravel agglomerating into clumps.

[0004] On one hand, a dispersing mechanism is provided, including a transport component and a dispersing mechanism disposed on the transport component. The dispersing mechanism includes a dispersing body and a support rod for fixing the dispersing body. Rotating elements are provided at both ends of the support rod. The dispersing mechanism can disperse sand and gravel that have agglomerated into clumps.

[0005] Furthermore, in an embodiment of the dispersing mechanism, the dispersing body is fixed to the support rod in a detachable or non-detachable manner.

[0006] Furthermore, in an embodiment of the dispersing mechanism, the dispersing mechanism further includes a fixing plate, the side of which is provided with a groove and a round hole, the rotating component is disposed in the round hole, and the groove can be engaged with the side plate of the transport component.

[0007] Furthermore, in an embodiment of the dispersing mechanism, the rotating component can be directly mounted on the transport assembly or mounted on the transport assembly via a fixing plate.

[0008] Furthermore, in an embodiment of the dispersing mechanism, the dispersing mechanism also includes a motor, an active sprocket is provided on the output shaft of the motor, a passive sprocket is provided at one end of the support rod, and the active sprocket and the passive sprocket are connected by a chain.

[0009] Furthermore, in an embodiment of the dispersing mechanism, the motor has a forward rotation mode, a reverse rotation mode, and a forward and reverse alternating mode, and the three modes are switched by a force sensor installed on the motor.

[0010] Furthermore, in an embodiment of the dispersing mechanism, the support rod is provided with at least one air inlet and at least one exhaust outlet, and the two ends of the support rod are provided with a first step and a second step, the rotating component is disposed on the first step, and the passive sprocket is disposed on the second step.

[0011] Furthermore, in an embodiment of the dispersing mechanism, the cross-section of the dispersing body can be set as triangular, elliptical, or circular.

[0012] On the other hand, a transport aircraft is provided, which includes the dispersing mechanism described in various embodiments.

[0013] Compared with the prior art, the present invention has the following technical effects:

[0014] 1. The conveyor is equipped with a dispersing mechanism, which can break up the aggregated sand and gravel in a timely manner, facilitating the transportation and storage of sand and gravel.

[0015] 2. The motor of the dispersing mechanism has three working modes: forward rotation mode, reverse rotation mode, and alternating forward and reverse rotation mode, which are switched by a force sensor installed on the motor. Different working modes can be freely switched according to the state of the sand and gravel. For example, when the force exerted by the sand and gravel on the dispersing mechanism is small, the motor operates in reverse rotation mode, which facilitates the rapid passage of sand and gravel; when the force exerted by the sand and gravel on the dispersing mechanism is moderate, the motor operates in forward rotation mode, which can quickly break up clumps of sand and gravel; when the force exerted by the sand and gravel on the dispersing mechanism is large, the motor operates in alternating forward and reverse rotation mode, which can break up tightly packed sand and gravel.

[0016] 3. The support rod of the dispersing mechanism is equipped with an air inlet and an exhaust outlet. High-pressure gas enters through the air inlet and flows out through the exhaust outlet, blowing off the sand and gravel remaining on the dispersing body, thus having a self-cleaning function.

[0029] refer to Figure 1 and Figure 2 This paper illustrates a dispersing mechanism for a sand and gravel belt conveyor, comprising a conveyor assembly 10 and a dispersing mechanism 20 disposed on the conveyor assembly 10. Preferably, the dispersing mechanism 20 is positioned in the middle of the conveyor assembly 10. The conveyor assembly 10 is provided with a belt and pulleys. Driven by an electric motor, the pulleys rotate, causing the belt to perform a cyclical motion, thereby conveying sand and gravel from one end of the belt to the other.

[0030] Continue to refer to Figure 3 and Figure 4The dispersing mechanism 20 includes a dispersing body 201 and a support rod 203 for fixing the dispersing body 201. Rotating elements 202 are provided at both ends of the support rod 203. In use, the dispersing mechanism 20 is fixed to the transport assembly 10. Sand and gravel are transported from one end to the other via a pulley. When loose sand and gravel come into contact with the dispersing mechanism 20, they can pass through directly or with minimal resistance. When agglomerated sand and gravel come into contact with the dispersing mechanism 20, they encounter greater resistance, and the dispersing mechanism 20 is passively rotated counterclockwise under the push of the sand and gravel, thereby dispersing the agglomerated sand and gravel.

[0031] The disintegrating component 201 can be detachably fixed to the support rod 203, such as by a threaded connection; or it can be non-detachably fixed to the support rod 203, such as by welding. The rotating component 202 can be directly installed on the side plate mounting position of the transport assembly 10.

[0032] Furthermore, for ease of installation, the disassembly mechanism also includes a fixing plate 204. The fixing plate 204 has a groove and a round hole on its side. The rotating component 202 is disposed in the round hole. The groove can be engaged with the side plate of the transport component 10.

[0033] Continue to refer to Figure 5 The diagram illustrates another structural form of the dispersing mechanism 20, which further includes a motor 205. A drive sprocket 206 is mounted on the output shaft of the motor 205, and a driven sprocket 207 is mounted on the support rod 203. The drive sprocket 206 and the driven sprocket are connected by a chain 208. In use, the motor 205 is in operation, driving the dispersing mechanism 20 to rotate via the chain 208. When clumps of sand and gravel come into contact with the dispersing mechanism 20, they are dispersed by the rotating mechanism.

[0034] Furthermore, motor 205 has three operating modes: forward rotation mode, reverse rotation mode, and alternating forward and reverse rotation mode, which are switched by a force sensor installed on motor 205. When the force applied by the sand and gravel to the dispersing mechanism 20 is small, motor 205 operates in reverse rotation mode, which facilitates the rapid passage of sand and gravel; when the force applied by the sand and gravel to the dispersing mechanism 20 is moderate, motor 205 operates in forward rotation mode, which can quickly disperse the agglomerated sand and gravel; when the force applied by the sand and gravel to the dispersing mechanism 20 is large, motor 205 operates in alternating forward and reverse rotation mode, which can disperse the tightly agglomerated sand and gravel.

[0035] Continue to refer to Figure 6The support rod 203 is provided with at least one air inlet 2031 and at least one exhaust outlet 2032. A first step 2033 and a second step 2034 are symmetrically arranged at both ends of the support rod 203. The first step 2033 is used to install the rotating component 202, and the second step 2034 is used to install the sprocket 207. In use, gas enters the support rod 203 through the air inlet 2031, circulates internally, and then exits through the exhaust outlet 2032, thereby blowing off the sand and gravel adhering to the agitator 201, achieving a self-cleaning effect.

[0036] Continue to refer to Figure 7-9 The cross-section of the dispersing body 201 can be set as triangular, elliptical, or circular. The advantage of this setting is that it can be applied to sand and gravel with different particle sizes. When the particle size of the sand and gravel is fine, the dispersing body 201 with elliptical and circular cross-sections is preferred, and the dispersing efficiency is high. When the particle size of the sand and gravel is coarse, the dispersing body 201 with triangular cross-section is preferred, and it cuts into the sand and gravel quickly.

[0037] On the other hand, a transport aircraft is provided, which includes a dispersing mechanism 20 according to various embodiments.

[0038] The specific embodiments described above are merely for the purpose of more clearly illustrating the principle of this utility model, wherein the various components are clearly shown or described to make the principle of this utility model easier to understand. Various modifications or variations can be easily made to this utility model by those skilled in the art without departing from the scope of this utility model. Therefore, it should be understood that all such modifications or variations should be included within the patent protection scope of this utility model.
