[0002] A scraper conveyor is a conveyor that uses a scraper chain to transport bulk materials within a trough. A scraper conveyor whose adjacent middle sections of the trough can bend to a limited extent in the horizontal and vertical planes is called a flexible scraper conveyor. After long-term use, especially with materials of excessive weight requiring excessive force from the scrapers, the drive chains on existing scraper conveyors are prone to loosening, which can lead to chain breakage and severely impact conveyor efficiency. Currently, loosening of the chain requires manual inspection by operators, necessitating manual labor. Furthermore, the chain's continuous movement during transport makes timely detection difficult and inconvenient, requiring considerable visual effort. Summary of the Invention

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, a conveyor chain detection device includes a body 2, characterized in that the body 2 includes a feed pipe 21, a conveying rod 22, and a transmission chain 23, wherein the feed pipe 21 is installed on the upper side of the body 2;

[0022] The top of the body 2 has a mounting base 3, on which a first drive motor 31 is mounted. A first drive wheel 32 is driven to the output shaft of the first drive motor 31. A drive belt 33 is driven to the first drive wheel 32. A second drive wheel 34 is driven to the drive belt 33. A conveying rod 22 is driven to the second drive wheel 34. A drive chain 23 is driven to the conveying rod 22 to drive the drive chain 23 to move.

[0023] By setting the first drive motor 31 to drive the first transmission wheel 32 and the second transmission wheel 34 to rotate, and then the second transmission wheel 34 to drive the transmission chain 23 to move, it is beneficial to automatically transport the machine body 2 and work the transmission chain 23, with a high degree of mechanization and automation.

[0024] Both sides of the inner wall of the body 2 are equipped with a test frame 4. A test seat 41 is fixed on the test frame 4. The test seat 41 includes a support column 42, a guide plate 43, a lower pressure plate 44, and a spring member 45. A first through hole 411 is opened on one side of the test seat 41. Two parallel spring seats 46 are symmetrically installed at the bottom of the test seat 41. Two spring members 45 are fixed in the spring seats 46. A lower pressure plate 44 is fixed on the spring member 45. A support column 42 is fixed on the lower pressure plate 44. A guide plate 43 is installed in the test seat 41, and the support column 42 passes through it. The guide plate 43 is located directly below the upper transmission chain 23; a protruding plate 47 is fixed on one side of the lower pressure plate 44, the protruding plate 47 passes through the first through hole 411, and the bottom of the protruding plate 47 has an abutment block 471; a pressure sensor 48 is installed on the detection frame 4, the sensor is located directly below the abutment block 471, and can abut against the abutment block 471; a detection panel 51 and a first warning light 52 are installed on one side of the body 2, and the pressure sensor 48 is connected to the detection panel 51 and the first warning light 52 through a wire.

[0025] In this invention, the pressure-sensitive sensor 48 and the detection panel 51 are existing technologies.

[0026] With the above structure, a detection seat 41 is set directly below the upper transmission chain 23. The support column 42 on the detection seat 41 is located directly below the upper transmission chain 23. If the transmission chain 23 becomes loose, it will droop downwards due to gravity and excessive looseness. After the transmission chain 23 droops down and abuts against the upper surface of the support column 42, the support column 42 moves downwards due to the downward force of the transmission chain 23. This causes the lower pressure plate 44 at the bottom of the support column 42 to press down, causing the spring 45 to contract. At the same time, the lower pressure plate 44... When pressed, its protruding plate 47 also presses down, causing the abutment block 471 to move downwards until it abuts against the pressure sensor 48. The pressure sensor 48 is subjected to the downward pressure of the abutment block 471, and transmits an electrical signal to the detection panel 51 through the wire. The first warning light 52 is also triggered through the wire. This helps to automatically detect abnormalities in the transmission chain 23 and reminds the operator in real time through the prompts on the detection panel 51 and the lighting of the first warning light 52. The detection efficiency is higher and the detection accuracy is also higher, which plays a very good role in detection and prompting.

[0027] Specifically, such as Figures 1 to 4 As shown, an infrared laser beam output end 61 is installed on one side of the inner wall of the machine body 2, and an infrared laser beam receiver end 62 is installed on the other side of the inner wall of the machine body 2. The relative height of the infrared laser beam output end 61, the infrared laser beam receiver end 62 and the upper transmission chain 23 is the same, and the infrared laser beam output end 61 is aligned with the upper transmission chain 23 and is blocked by the upper transmission chain 23.

[0028] In this invention, the infrared laser beam output end 61 and the infrared laser beam receiving end 62 are existing technologies.

[0029] With the above structure, by setting up an infrared laser output end 61 and an infrared laser receiver end 62, when the chain is working normally, the infrared rays output by the infrared laser output end 61 can only reach the position of the transmission chain 23. However, when the chain is abnormally loose or sagging, the infrared laser output end 61 can emit infrared rays to the infrared laser receiver end 62. The infrared laser receiver end 62 receives the infrared rays from the infrared laser output end 61 and transmits them to the detection panel 51 through an electrical signal, which plays a dual role of warning and detection, and the detection effect is better and more accurate.

[0030] like Figures 1 to 4 As shown, a second warning light 53 and a detection panel 51 are connected to one side of the infrared laser beam receiver 62 via wires. The second warning light 53 serves to provide multiple warnings, reminding operators and improving detection efficiency and accuracy, thus providing excellent detection guidance.

[0031] like Figures 1 to 4 As shown, the testing frame 4 has a connecting part 7, which is connected and fixed to the inner walls of both sides of the machine body 2 by screws. Installing the connecting part 7 of the testing frame 4 onto the inner walls of both sides of the machine body 2 with screws facilitates a secure fixation and makes the structure more stable.

[0032] like Figures 1 to 4 As shown, the support column 42 has several sliding parts 81 arranged around it as the center. The guide plate 43 has a second through hole 82, and several sliding grooves 83 matching the sliding parts 81 are formed around the second through hole 82. The sliding parts 81 and the sliding grooves 83 are slidably engaged, allowing the support column 42 to move within the guide plate 43. This slidable engagement of the sliding parts 81 and the sliding grooves 83 facilitates the upward or downward movement of the support column 42 within the guide plate 43, making movement more flexible and convenient. Simultaneously, the second through hole 82 of the guide plate 43 provides excellent guidance, preventing the support column 42 from shifting and improving detection accuracy.

[0033] like Figures 1 to 4 As shown, material scrapers 24 are installed on both sides of the transmission chain 23. By setting up material scrapers 24, the material conveying efficiency can be improved.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0035] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
