[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, reference Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides a force-bearing mechanism that enables quick assembly and disassembly. It includes a material blocking component 100. When material being transported by the belt overflows due to a blockage, the overflowing material presses against the material blocking component 100, causing it to rotate and trigger a detection component. The material blocking component 100 includes a material blocking assembly 101, a fixing assembly 102 disposed below the material blocking assembly 101, and a connecting assembly 103 disposed on the fixing assembly 102.

[0035] The material blocking assembly 101 includes a material blocking plate 101 a and a rotating plug-in plate 102 b disposed at the lower portion of the material blocking assembly 101 .

[0036] A connecting column 102a is welded between the baffle plate 101a and the rotating plug plate 102b. The height of the connecting column 102a is equal to the thickness of the connecting plate 103a, so that the connecting plate 103a is fixedly clamped between the baffle plate 101a and the rotating plug plate 102b.

[0037] An angle is set between the baffle plate 101a and the rotating plug-in plate 102b along the central axis, and the angle is set to 90±10 degrees; the angle between the baffle plate 101a and the rotating plug-in plate 102b is set in such a way that the connecting plate 103a is fixed between the baffle plate 101a and the rotating plug-in plate 102b in a staggered manner, and the baffle assembly 101 can be disassembled at any time.

[0038] The fixing assembly 102 includes a transversely arranged connecting plate 103a, one end of which is welded with a vertical supporting plate 103b, forming an inverted L-shape between the connecting plate 103a and the supporting plate 103b; the L-shaped structure of the fixing assembly 102 can also be formed by bending a steel plate.

[0039] An elongated plug-in hole 103a-1 is processed on the connecting plate 103a along the length direction. The size of the plug-in hole 103a-1 is comparable to that of the rotating plug-in plate 102b so that the rotating plug-in plate 102b can pass through it. After the rotating plug-in plate 102b is fully inserted into the plug-in hole 103a-1, the baffle plate 101a is rotated. When the baffle plate 101a is perpendicular to the support plate 103b, the connecting plate 103a can be stably clamped between the baffle plate 101a and the rotating plug-in plate 102b, so that the baffle assembly 101 is fixedly connected to the fixed assembly 102.

[0040] It should be noted that the horizontal length of the rotating plug plate 102b is smaller than the horizontal length of the blocking plate 101a, so as to prevent the blocking plate 101a from falling from the plug hole 103a-1.

[0041] Preferably, the material blocking assembly 101 further includes reinforcing ribs 101a-1, which are arranged on both sides of the material blocking plate 101a. The bottom surface of the reinforcing ribs 101a-1 abuts against the top surface of the connecting plate 103a, thereby increasing the impact resistance of the material blocking plate 101a.

[0042] When in use, the rotating plug plate 102b is inserted along the plug hole 103a-1 until the bottom surface of the reinforcing rib 101a-1 abuts the top surface of the connecting plate 103a; rotate the baffle plate 101a until the baffle plate 101a is perpendicular to the support plate 103b, and the rotating plug plate 102b is rotated accordingly to a corresponding angle so that the connecting plate 103a is fixedly engaged between the baffle plate 101a and the rotating plug plate 102b; when the baffle assembly 101 needs to be replaced, rotate the baffle plate 101a to align the rotating plug plate 102b with the plug hole 103a-1, and then pull out the rotating plug plate 102b to complete the separation of the baffle assembly 101 and the fixed assembly 102.

[0043] Example 2, reference Figures 3 to 8 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides another fixing method of the force-bearing mechanism.

[0044] The material blocking component 100 includes the same material blocking assembly 101 and connecting assembly 103 as those in Example 1, except that the vertical plug-in plate 102c is formed by extending the material blocking plate 101a downward, that is, the vertical plug-in plate 102c and the material blocking plate 101a are made of a whole piece of stainless steel plate.

[0045] A plurality of fixing grooves 102c-1 are respectively formed on two opposite sides of the vertical plug-in board 102c. A guide groove 102c-2 is formed on the fixing groove 102c-1. The guide groove 102c-2 is communicated with the bottom end of the vertical plug-in board 102c.

[0046] The bottom of the vertical plug-in board 102c is detachably sleeved with a limit plate 102d, and a through-set plug-in slot 102d-1 is provided in the limit plate 102d, and the plug-in slot 102d-1 is suitable for inserting the vertical plug-in board 102c; roller shafts 102d-2 are symmetrically arranged in the plug-in slot 102d-1, and a roller 102d-3 is sleeved on the roller shaft 102d-2, and the roller 102d-3 is suitable for being fixed in the fixing slot 102c-1.

[0047] It should be noted that the number of rollers 102d-3 is consistent with the number of fixed slots 102c-1, and their positions correspond; when the vertical plug-in plate 102c is inserted into the plug-in slot 102d-1, the roller 102d-3 rolls along the guide slot 102c-2, rolls into the fixed slot 102c-1 and is fixed in the fixed slot 102c-1, so that the limit plate 102d is fixedly sleeved on the lower part of the vertical plug-in plate 102c; that is, after the vertical plug-in plate 102c is plugged through the connecting plate 103a, the lower part of the vertical plug-in plate 102c is fixedly connected to the connecting assembly 103, thereby preventing the material blocking assembly 101 from falling off from the connecting assembly 103, and completing the fixed connection between the material blocking assembly 101 and the connecting assembly 103.

[0048] Preferably, after the connection component 103 and the vertical plug-in plate 102 c are fixed, the top surface of the connection component 103 abuts against the bottom surface of the connection plate 103 a to prevent shaking between the blocking component 101 and the connection component 103 .

[0049] After the limiting plate 102d is completely separated from the vertical plug-in plate 102c, the blocking assembly 101 is pulled out from the plug-in hole 103a-1, and the disassembly of the blocking assembly 101 and the connecting assembly 103 is completed.

[0050] In summary, no matter which fixing method is adopted in the above embodiments, the installation and replacement of the material blocking assembly 101 are facilitated.

[0051] Example 3, reference Figures 9-10 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides an external belt blockage and overflow detection device, which solves the problem of timely alarm after belt blockage and overflow; it includes the detection mechanism in the above embodiment.

[0052] The device further includes a detection component 200 , which includes a housing component 201 , and a reset component 202 is disposed in the housing component 201 .

[0053] The housing assembly 201 includes a left housing 201a and a right housing 201b. A sealing strip is provided between the left housing 201a and the right housing 201b to prevent dust and other debris from entering the housing assembly 201. The left housing 201a and the right housing 201b are fixed by bolts.

[0054] Furthermore, a first stop rib 201a-1 and a second stop rib 201a-2 are provided on the outer side wall of the left shell 201a; the connecting component 103 can swing between the first stop rib 201a-1 and the second stop rib 201a-2.

[0055] Specifically, when support plate 103b rotates about its rotation point, it is restricted by first stop rib 201a-1 and second stop rib 201a-2, limiting the maximum rotation angle of connecting assembly 103 to 75 degrees. It should be noted that first stop rib 201a-1 is provided to prevent support plate 103b from excessively rotating and damaging torsion spring 202c, which would prevent support plate 103b from returning to its original position. Therefore, even if material leakage continues, support plate 103b can only rotate between first stop rib 201a-1 and second stop rib 201a-2.

[0056] Furthermore, the reset assembly 202 includes a transmission shaft 202a, one end of which is located inside the left shell 201a, and the other end extends outside the left shell 201a and is fixedly connected to the support plate 103b. The fixed connection between the support plate 103b and the transmission shaft 202a is the rotation point of the support plate 103b.

[0057] The reset assembly 202 further includes a cam 202b, a torsion spring 202c, and a micro switch 202d.

[0058] The torsion spring 202c and the cam 202b are sequentially sleeved on one end of the transmission shaft 202a located inside the left housing 201a.

[0059] The two ends of the torsion spring 202c are fixedly connected to the transmission shaft 202a and the inner wall of the left shell 201a respectively, and the torsion spring 202c has a preset torque so that the transmission shaft 202a always keeps twisting in the direction of the second stop rib 201a-2; after the material impacts the material, the baffle plate 101a drives the transmission shaft 202a to rotate. After the impact force of the material disappears, the torsion spring 202c drives the transmission shaft 202a to rotate, and further drives the baffle plate 101a to resume the state of contact with the second stop rib 201a-2.

[0060] The cam 202b is fixedly connected to the transmission shaft 202a and rotates along with the rotation of the transmission shaft 202a.

[0061] The micro switch 202d is fixedly disposed above the cam 202b, and the movement trajectory of the cam 202b can touch the micro switch 202d.

[0062] It should be noted that the micro switch 202d circuit is incorporated into the belt conveyor control system. When the belt is blocked or overflowing, the baffle plate 101a rotates, triggering the micro switch 202d to send a blockage alarm signal, causing the belt conveyor and upstream equipment to shut down in a chain reaction to prevent the blockage from worsening.

[0063] Preferably, in order to avoid malfunction, a time delay relay is installed on the control circuit of the micro switch 202d, and the delay time of the material blockage alarm can be adjusted automatically.

[0064] When in use, the device is tilted outward along the center line of the belt at an angle of 30±5 degrees and symmetrically fixed on both sides of the position where the belt is prone to blockage; after blockage and overflow, the material falls from the belt and impacts the baffle plate 101a, and the baffle plate 101a drives the support plate 103b to rotate, thereby causing the drive shaft 202a to rotate, and the drive shaft 202a drives the cam 202b to rotate; after the cam 202b rotates a certain angle, it will touch the micro switch 202d, and after the micro switch 202d is touched, it will send a blockage alarm signal, causing the belt conveyor and upstream equipment to stop in a chain reaction to avoid further deterioration of the blockage.

[0065] In summary, this device can promptly detect blockages and overflows during belt material transportation, which is conducive to the smooth progress of production; at the same time, the structure of the force-bearing mechanism saves the time for replacing the baffle plate, and improves production efficiency as a whole.
