This technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in view of the shortcomings of the existing technology, a material conveyor belt puncture and tear alarm device is provided which has a simple structure and can conveniently and reliably monitor the condition of the conveyor belt and promptly issue an alarm when the conveyor belt is seriously punctured or torn.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0006] The present invention relates to a piercing and tearing alarm device for a material conveyor belt. The conveyor belt includes an upper conveying layer and a lower return layer. A connecting rod member and a travel switch are installed on a first bracket on one side of the conveyor belt. The connecting rod member is movably connected to a receiving hopper, and the other end of the receiving hopper is located below the travel switch. A falling material cleaning component is installed on a second bracket on the other side of the conveyor belt.

[0007] The connecting rod member is vertically arranged. The lower end of the connecting rod member is movably connected to the receiving hopper through a pin shaft. A receiving hopper limiting rod is also provided on the first bracket, and it is arranged at a position close to one end of the receiving hopper.

[0008] The falling material cleaning component includes a telescopic cylinder, a push rod, and a push plate. The telescopic cylinder is fixedly installed on the second bracket on the other side of the conveyor belt. One end of the push rod is fixedly connected to the telescopic rod of the telescopic cylinder, and the other end of the push rod is fixedly connected to the push plate. The push plate is attached to the upper surface of the lower return layer of the conveyor belt.

[0009] A counterweight is provided at the other end of the receiving hopper, and the counterweight is located below the travel switch.

[0010] When there is no material in the receiving hopper, the receiving hopper limiting rod on the first bracket is arranged to abut against one side edge position of the receiving hopper.

[0011] The falling material cleaning component is arranged to be able to push the material that passes through the upper conveying layer of the conveyor belt and lands on the upper surface of the lower return layer of the conveyor belt onto the receiving hopper.

[0012] When there is no material in the receiving hopper, the counterweight is arranged to be in a non-contact state with the travel switch.

[0013] When the material received in the receiving hopper exceeds the set weight, the counterweight is arranged to be in a contact state with the travel switch.

[0014] The travel switch is connected to an alarm.

[0015] The first bracket and the second bracket are arranged along the extending direction of the conveyor belt.

[0016] Adopting the technical solution of the present invention, the working principle and beneficial effects are as follows:

[0017] The material conveyor belt puncture and tear alarm device described in the present invention has a conveyor belt in a ring structure. The conveyor belt is sleeved on conveyor rollers, such that the conveyor belt forms an upper conveying layer and a lower return layer. The upper conveying layer of the conveyor belt is used for conveying materials. On one side of the conveyor belt, a connecting rod member and a travel switch are installed on a first bracket. The connecting rod member is movably connected to a receiving hopper, and the other end of the receiving hopper is located below the travel switch; on the other side of the conveyor belt, a falling material cleaning component is installed on a second bracket. After a sharp object in the material punctures the upper conveying layer of the conveyor belt, the powdered material conveyed by the conveyor belt will pass through the crack formed by the puncture on the back of the upper conveying layer of the conveyor belt and fall on the upper surface of the lower return layer of the conveyor belt. By applying force to the material through the falling material cleaning component, the falling material is pushed into the receiving hopper. The more severe the puncture, the more material will fall into the receiving hopper within a set time. After the receiving hopper receives the material, it will continuously move downward, driving the other end of the receiving hopper to tilt upward. When the material falling into the receiving hopper exceeds the set weight, the receiving hopper will contact the travel switch, triggering an alarm and sending a signal to the on-site personnel to remind that the conveyor belt is severely punctured and needs to be replaced. When the conveyor belt is not punctured, no material will fall, the receiving hopper will not move downward, and no alarm will occur, ensuring the normal material conveying of the conveyor belt. In this way, with only a simple structural arrangement, the condition of the conveyor belt can be monitored, effectively meeting the usage requirements and avoiding the problem of material loss caused by continued use of the conveyor belt with severe puncture and tear.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes in detail the specific embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships of the various components involved, the functions of each part and the working principles, etc., with reference to the drawings:

[0023] As shown in the attached...Figure 1 , as shown in Figure 2 . The present invention is a piercing and tearing alarm device for a material conveyor belt. The conveyor belt includes an upper conveying layer 1 and a lower return layer 2 of the conveyor belt. A connecting rod member 4 and a travel switch 5 are installed on a first bracket 3 on one side of the conveyor belt. The connecting rod member 4 is movably connected to a receiving hopper 6, and the other end of the receiving hopper 6 is located below the travel switch 5. A falling material cleaning component 8 is installed on a second bracket 7 on the other side of the conveyor belt. With the above structure, in view of the deficiencies in the prior art, an improved technical solution is proposed. When setting the structure, the conveyor belt is a ring structure, and the conveyor belt is sleeved on the conveying rollers, so that the conveyor belt forms an upper conveying layer 1 and a lower return layer 2 of the conveyor belt. The upper conveying layer 1 of the conveyor belt is used for conveying materials. And a connecting rod member 4 and a travel switch 5 are installed on a first bracket 3 on one side of the conveyor belt. The connecting rod member 4 is movably connected to a receiving hopper 6, and the other end of the receiving hopper 6 is located below the travel switch 5. A falling material cleaning component 8 is installed on a second bracket 7 on the other side of the conveyor belt. After a sharp object mixed in the material pierces the upper conveying layer 1 of the conveyor belt, the powdered material conveyed by the conveyor belt will pass through the crack formed by the piercing of the back of the upper conveying layer 1 and fall on the upper surface of the lower return layer 2 of the conveyor belt. By applying force to the material through the falling material cleaning component 8, the falling material is pushed into the receiving hopper 6. The more serious the piercing, the more material will fall into the receiving hopper 6 within the set time. After the receiving hopper 6 receives the material, it will continue to move downward, driving the other end of the receiving hopper 6 to tilt upward. And when the material falling into the receiving hopper 6 exceeds the set weight, the receiving hopper 6 will contact the travel switch 5, triggering an alarm and sending a signal to the on-site personnel to remind that the piercing of the conveyor belt is serious and needs to be replaced. When the conveyor belt is not pierced, no material will fall, the receiving hopper will not move downward, and no alarm will occur, ensuring the normal material conveying of the conveyor belt. In this way, only through a simple structure setting, the condition of the conveyor belt can be monitored, effectively meeting the use requirements and avoiding the occurrence of material loss problems caused by continued use of the conveyor belt with serious piercing and tearing. The piercing and tearing alarm device for the material conveyor belt of the present invention has a simple structure and can conveniently and reliably monitor the condition of the conveyor belt. When the conveyor belt has serious piercing and tearing problems, an alarm is given in time.

[0024] The connecting rod member 4 is vertically arranged. The lower end of the connecting rod member 4 is movably connected to the receiving hopper 6 through a pin shaft 9. A receiving hopper limiting rod 10 is also provided on the first bracket 3, and the receiving hopper limiting rod 10 is arranged at a position close to one end of the receiving hopper 6. With the above structure, the receiving hopper can swing relative to the connecting rod member, so that after the receiving hopper receives the material, the other end of the receiving hopper can tilt up.

[0025] The described falling material cleaning component 8 includes a telescopic cylinder 11, a push rod 12, and a push plate 13. The telescopic cylinder 11 is fixedly installed on the second bracket 7 on the other side of the conveyor belt. One end of the push rod 12 is fixedly connected to the telescopic rod of the telescopic cylinder 11, and the other end of the push rod 12 is fixedly connected to the push plate 13. The push plate 13 is attached to the upper surface of the lower return layer 2 of the conveyor belt. The push plate and the conveyor belt form an acute angle structure. With the above structure, during the process of the conveyor belt transporting materials, the falling material cleaning component 8 can always be in an operating state, or the falling material cleaning component 8 can be started regularly. If there are materials falling, the falling material cleaning component 8 can reliably push the materials into the receiving hopper. The falling material cleaning component 8 cooperates with the receiving hopper to monitor the state of the conveyor belt.

[0026] A counterweight 14 is arranged at the other end of the described receiving hopper 4, and the counterweight 14 is located below the travel switch 5. With the above structure, the setting of the counterweight 14 exerts a pressure on the receiving hopper when there is no material falling into the receiving hopper, avoiding the receiving hopper randomly contacting the travel switch and preventing false alarms.

[0027] When there is no material received on the receiving hopper 6, the receiving hopper limiting rod 10 on the first bracket 3 is arranged to abut against one side edge position of the receiving hopper 6. With the above structure, the setting of the receiving hopper limiting rod 10 exerts a force on the receiving hopper 6 from one side of the receiving hopper 6 when there is no material falling into the receiving hopper 6, and together with the counterweight 14 on the other side, ensures that the receiving hopper is in a horizontal state.

[0028] The described falling material cleaning component 8 is arranged to be able to push the materials that pass through the upper conveying layer 1 of the conveyor belt and fall on the upper surface of the lower return layer 2 of the conveyor belt onto the receiving hopper 6. With the above structure, the falling material cleaning component 8 can reliably realize the pushing and falling of the falling materials.

[0029] When there is no material received on the receiving hopper 6, the counterweight 14 is arranged to be in a non-contact state with the travel switch 5. With the above structure, when there is no material falling into the receiving hopper, the state balance of the receiving hopper will not be broken, and there will be no alarm at this time. When the material received on the receiving hopper 6 exceeds the set weight, the counterweight 14 is arranged to be in a contact state with the travel switch 5. With the above structure, when the material falls and exceeds the set weight, the balance is broken and an alarm is issued.

[0030] The described travel switch 5 is connected to an alarm. With the above structure, when the balance of the receiving hopper is broken, the counterweight tilts upward to contact the travel switch, and then the alarm issues an alarm to remind.

[0031] The described first bracket 3 and second bracket 7 are arranged along the extending direction of the conveyor belt.

[0032] The material conveyor belt piercing and tearing alarm device described in the present invention, when the structure is set, the conveyor belt is in a ring structure and is sleeved on the conveyor rollers, so that the conveyor belt forms an upper conveyor layer 1 and a lower return layer 2 of the conveyor belt. The upper conveyor layer 1 of the conveyor belt is used for conveying materials. A connecting rod member 4 and a travel switch 5 are installed on the first bracket 3 on one side of the conveyor belt. The connecting rod member 4 is movably connected to the receiving hopper 6, and the other end of the receiving hopper 6 is located below the travel switch 5; a falling material cleaning component 8 is installed on the second bracket 7 on the other side of the conveyor belt. After the sharp objects mixed in the materials pierce the upper conveyor layer 1 of the conveyor belt, the powdery materials conveyed by the conveyor belt will pass through the cracks formed by the piercing of the back of the upper conveyor layer 1 and fall on the upper surface of the lower return layer 2 of the conveyor belt. By applying force to the materials by the falling material cleaning component 8, the falling materials are pushed into the receiving hopper 6. The more serious the piercing is, the more materials will fall into the receiving hopper 6 within the set time. After the receiving hopper 6 receives the materials, it will continue to move downward, driving the other end of the receiving hopper 6 to tilt upward. When the materials falling into the receiving hopper 6 exceed the set weight, the receiving hopper 6 will contact the travel switch 5, trigger an alarm, and send a signal to the on-site personnel to remind that the piercing of the conveyor belt is serious and needs to be replaced. When the conveyor belt is not pierced, no materials will fall, the receiving hopper will not move downward, and no alarm will occur, ensuring that the conveyor belt can normally convey materials. In this way, only with a simple structural setting, the condition of the conveyor belt can be monitored, effectively meeting the use requirements and avoiding the occurrence of material loss problems caused by continued use of the conveyor belt with serious piercing and tearing.

[0033] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
