Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor technology, specifically, it relates to an anti-clogging device for belt conveyors. Background Technology

[0002] In the field of industrial material conveying, belt conveyors are widely used as key equipment, and the anti-blocking device of the head pulley plays a crucial role in ensuring their stable operation. Most existing belt conveyors adopt an anti-blocking solution based on limit switches. The limit switch consists of an operating head, a contact system, and a housing. The contact state is changed by external mechanical actuation of the operating head, thereby controlling the on / off state of the control circuit.

[0003] However, actual production conditions are complex and varied, and the particle size, moisture content, viscosity and other characteristics of materials vary greatly. Often, the material cannot effectively push the rotating iron plate due to its own characteristics, which causes the limit switch to not act accurately and cannot transmit the material blockage information to the control system in a timely manner. This makes it impossible to deal with the material blockage problem in time, which in turn causes belt conveyor failure and affects the continuity of production.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an anti-blocking device for belt conveyors.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An anti-clogging device for a belt conveyor includes: a belt conveyor body, a head pulley cover installed on the upper side of the belt conveyor body, a fixing frame installed inside the head pulley cover, a grid installed on the inner wall of the fixing frame, a feed shell fixedly connected to one side of the head pulley cover, a discharge port opened on the other side of the head pulley cover, and an adjustment mechanism installed inside the head pulley cover.

[0008] By setting up a grid, when faced with materials of varying viscosity, the angle of the grid can be adjusted using an adjustment mechanism. For highly viscous materials, the angle can be increased, allowing gravity to help them pass through the screen quickly and avoid accumulation. For materials with poor flowability, adjusting the angle appropriately can optimize their slippage path. This adjustment allows the grid to flexibly adapt to materials, maintain efficient conveying, effectively reduce the chance of material blockage, and ensure smooth operation of the belt conveyor.

[0009] Preferably, the adjustment mechanism includes sliding grooves on both sides of the inner wall of the head wheel cover, with sliders slidably fitted on the inner wall of the sliding grooves, and guide grooves on both sides of the head wheel cover, with guide rods slidably fitted on the inner wall of the guide grooves, and a connecting plate fixedly connected to one end of one of the two guide rods.

[0010] Preferably, the fixing frame is rotatably fitted between the two sliders, and the fixing frame is fixedly connected between the two guide rods.

[0011] Preferably, one side of the head wheel cover has multiple insertion holes, and a plug rod is slidably fitted on the connecting plate. A tension spring is sleeved on the plug rod, and the plug rod cooperates with the insertion hole.

[0012] Preferably, the two ends of the tension spring are fixedly connected to the insert rod and the connecting plate, respectively.

[0013] Preferably, a ball head seat is installed on the upper side of the inner wall of the head wheel cover, a ball head rod is movably fitted on the inner wall of the ball head seat, and a mercury tilt switch is installed at the lower end of the ball head rod.

[0014] Preferably, an inspection door is hinged to one side of the head wheel cover, two spring clips are fixedly connected to one side of the inspection door, and two mating blocks that cooperate with the spring clips are fixedly connected to one side of the head wheel cover.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] By setting up a grid, when faced with materials of varying viscosity, the angle of the grid can be adjusted using an adjustment mechanism. For highly viscous materials, the angle can be increased, allowing gravity to help them pass through the screen quickly and avoid accumulation. For materials with poor flowability, adjusting the angle appropriately can optimize their slippage path. This adjustment allows the grid to flexibly adapt to materials, maintain efficient conveying, effectively reduce the chance of material blockage, and ensure smooth operation of the belt conveyor.

[0035] Example 1

[0036] Please refer to Figure 1-5 A material blocking device for a belt conveyor includes: a belt conveyor body 1; a head pulley cover 2 mounted on the upper side of the belt conveyor body 1; a fixing frame 3 installed inside the head pulley cover 2; a grid 4 installed on the inner wall of the fixing frame 3; a feed shell 5 fixedly connected to one side of the head pulley cover 2; a discharge port 6 opened on the other side of the head pulley cover 2; and an adjusting mechanism 7 installed inside the head pulley cover 2. A ball joint seat 11 is mounted on the upper side of the inner wall of the head pulley cover 2; a ball joint rod 12 is movably fitted to the inner wall of the ball joint seat 11; and a mercury tilt switch 13 is mounted on the lower end of the ball joint rod 12. A maintenance door 14 is hinged to one side of the head pulley cover 2; two spring clips 15 are fixedly connected to one side of the maintenance door 14; and two mating blocks 16 that cooperate with the spring clips 15 are fixedly connected to one side of the head pulley cover 2.

[0037] Implementation process: Material enters the head pulley cover 2 from the feed shell 5 and first comes into contact with the grid 4 set on the inner wall of the fixed frame 3. The grid 4, with its specific screen hole structure, performs preliminary screening of the material, intercepting large pieces of material and preventing them from entering the critical head pulley operating area and causing blockage. The ball head seat 11 on the upper side of the inner wall of the head pulley cover 2 cooperates with the ball head rod 12, so that the mercury tilt switch 13 can sensitively sense the material accumulation in the head pulley cover 2. Once the material accumulation causes the tilt angle of the head pulley cover 2 to exceed the set 15°, the mercury in the mercury tilt switch 13 flows under the action of gravity, connecting or disconnecting the internal circuit, and quickly sending a signal to the control system to trigger the belt conveyor to stop in an interlocking manner, so as to avoid the material blockage from worsening. During routine maintenance, the maintenance door 14 hinged on one side of the head pulley cover 2 can be opened. The maintenance door 14 cooperates with the mating block 16 on one side of the head pulley cover 2 through the spring buckle 15, so as to realize convenient opening and closing, which makes it convenient for staff to maintain and clean the internal components of the head pulley cover 2.

[0038] Benefits of implementation: The grid 4 accurately intercepts large pieces of material, ensuring that only materials that meet the particle size requirements enter the subsequent conveying process, reducing the risk of material blockage at the source and ensuring the stable operation of the belt conveyor. Compared with traditional monitoring methods, the mercury tilt switch 13 can react quickly in the early stage of material accumulation, giving the inspectors enough time to deal with the problem, effectively avoiding downtime caused by large accumulation of material, and ensuring the continuous operation of the production line.

[0039] Example 2

[0040] The adjustment mechanism 7 includes sliding grooves 71 formed on both sides of the inner wall of the head wheel cover 2. Sliding blocks 72 are slidably fitted onto the inner walls of the sliding grooves 71. Guide grooves 73 are formed on both sides of the head wheel cover 2, and guide rods 74 are slidably fitted onto the inner walls of the guide grooves 73. One end of one of the guide rods 74 is fixedly connected to a connecting plate 75. A fixing frame 3 is rotatably fitted between the two sliding blocks 72 and fixedly connected between the two guide rods 74. Multiple insertion holes 8 are formed on one side of the head wheel cover 2. Insertion rods 9 are slidably fitted onto the connecting plate 75, and tension springs 10 are sleeved on the insertion rods 9, which engage with the insertion holes 8. The two ends of the tension springs 10 are fixedly connected to the insertion rods 9 and the connecting plate 75, respectively.

[0041] Implementation process: During the production process, if it is necessary to adjust the position and angle of the grid 4 according to the material characteristics or conveying conditions, this is achieved through the adjustment mechanism 7. The sliding connecting plate 75 drives the guide rod 74 to slide in the guide groove 73, and drives the slider 72 to slide in the slide groove 71, so that the fixed frame 3 can flexibly change its posture. When adjustment is required, pull the insertion rod 9 to disengage it from the insertion hole 8, overcoming the elastic force of the tension spring 10. At this time, the connecting plate 75 can be moved, driving the guide rod 74 and the fixed frame 3 to make fine adjustments to their positions. After the adjustment is completed, release the insertion rod 9, and the insertion rod 9 is reinserted into the insertion hole 8 under the action of the tension spring 10. When the guide rod 74 moves to the rightmost side in the guide groove 73, it drives the fixed frame 3 and the grid 4 to rotate under the guidance of the guide groove 73, thereby realizing the angle adjustment of the grid 4.

[0042] Benefits of implementation: The adjustment mechanism 7 allows the grid 4 to be adjusted in real time according to different material characteristics, flow rate and other working conditions, which is highly adaptable and maintains the efficient rhythm of material conveying.
