However, these terms may vary according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art.

Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.
[0025] Referring to Figure 1 , this embodiment provides a protection mechanism, including,
[0026] A protection component 1, the protection component 1 includes a discharging component 11, a support component 12 installed outside the discharging component 11, a fixing component 13 installed outside the support component 12, a rotating component 14 installed outside the fixing component 13, and a power component 15 installed outside the fixing component 13.
[0027] The discharging component 11 includes a discharging hopper 111 and a first support column 112 fixedly connected to the outside of the discharging hopper 111.
[0028] When equipment such as ship unloaders, portal cranes, and cranes transport bulk materials to the conveying location, the materials can be put into the discharging hopper 111. The discharging hopper 111 is in a funnel shape and can guide the materials above the conveyor belt.
[0029] By providing the discharging hopper 111, when discharging bulk materials, the materials can be accurately guided above the conveyor belt by the discharging hopper 111, and there will be no overflow and spillage.
[0030] As an embodiment provided in the present application, as Figures 1 to 3 , the support component 12 includes an outer eaves 121 fixedly connected to the outside of the discharging hopper 111 and a support column 122 fixedly connected to the outside of the outer eaves 121.
[0031] The fixing component 13 includes a static plate 131 fixedly connected to the outside of the outer eaves 121 and the support column 122, a static hole 132 opened inside the static plate 131, and a central column 133 fixedly connected to the outside of the static plate 131.
[0032] The rotating assembly 14 includes a dynamic plate 141 rotatably connected to the outside of the central column 133, external teeth 142 provided on the outside of the dynamic plate 141, a dynamic hole 143 opened inside the dynamic plate 141, and a slope 144 opened inside the dynamic hole 143.
[0033] The power assembly 15 includes a bracket 151 fixedly connected to the outside of the static plate 131, a motor 152 adaptively installed inside the bracket 151, and a gear 153 adaptively installed on the output shaft of the motor 152.
[0034] Among them, a baffle can be provided outside the fixed assembly 13 and the rotating assembly 14 to prevent bulk materials from scattering outside the fixed assembly 13 and the rotating assembly 14 during unloading.
[0035] It is worth noting that the dynamic plate 141 is stacked and installed above the static plate 131 with a spacing of c centimeters. After the static plate 131 and the dynamic plate 141 are stacked, they are placed above the discharge hopper 111 at an angle of about 15 degrees to the ground. The static plate 131 and the dynamic plate 141 have the same diameter, and are designed according to the actual diameter of the discharge hopper 111, slightly larger than the diameter of the discharge hopper 111 to achieve full coverage.
[0036] The dynamic hole 143 and the static hole 132 are set to be circular. The diameter of the dynamic hole 143 is a centimeters, and the diameter of the static hole 132 is b centimeters. Among them, a > c > b. For example, a can be taken as 15, b as 10, and c as 5.
[0037] In the working state, the motor 152 is started, and the motor 152 drives the dynamic plate 141 to rotate through the gear 153.
[0038] When bulk materials accompanied by vertically falling long hard objects fall on the dynamic plate 141, the long hard objects that do not align with the dynamic hole 143 will fall outside the dynamic plate 141, thus tipping over and rolling down along the inclined dynamic plate 141.
[0039] The long hard objects that align with the dynamic hole 143 will fall into the dynamic hole 143. However, since the dynamic hole 143 rotates with the dynamic plate 141 all the time, the time when the dynamic hole 143 coincides with the static hole 132 is very short. Most of the long hard objects passing through the dynamic hole 143 will not directly pass through the static hole 132 and fall onto the conveyor belt, but will rotate with the dynamic plate 141 until the dynamic hole 143 coincides with the static hole 132, and then pass through the static hole 132.
[0040] During this process, when a long and strip-shaped hard object passes through the dynamic plate 141 but not through the static plate 131, blocked by the static plate 131, the long and strip-shaped hard object has stopped falling. When the dynamic hole 143 coincides with the static hole 132 and continues to pass through the static hole 132, the initial falling speed of the long and strip-shaped hard object is relatively low, and it is very easy for the long and strip-shaped object to be stuck by the rotating dynamic plate 141 before it completely passes through the dynamic hole 143 and the static hole 132. At this time, if the rotating dynamic plate 141 can crush the long and strip-shaped hard object, it can continue to fall onto the conveyor belt, and the crushed and slowed-down hard object will not damage the conveyor belt. If the hard object is not crushed, the dynamic plate 141 will be stuck. At this time, an electrical control fault alarm will stop the machine, the motor 152 will stop rotating, and it will be repaired by the staff.
[0041] Through the above solution, the damage to the conveyor belt caused by long and strip-shaped hard objects passing through the dynamic hole 143 but not immediately passing through the static hole 132 can be solved.
[0042] In addition, for the situation where a long and strip-shaped hard object happens to coincide with the dynamic hole 143 and the static hole 132 during falling and the long and strip-shaped hard object passes through the dynamic hole 143 and the static hole 132 at the same time, the rotation speed of the motor 152 can be increased to shorten the time when the dynamic hole 143 and the static hole 132 have an overlapping area, so that the long and strip-shaped object will be stuck before it completely passes through, thereby reducing the risk of damage to the conveyor belt.
[0043] In addition, most of the bulk materials are yellow sand, stones, coal, iron ore, etc., which are easy to form lumps due to moisture. When the lumped bulk materials fall into the dynamic plate 141 with a larger diameter, since the diameter of the static hole 132 is smaller, they cannot pass through the static hole 132. At this time, the lumped materials will rotate and move along with the dynamic plate 141, so that the lumped materials will rub against the top surface of the static plate 131, and the volume of the lumped materials gradually decreases until they can pass through the static hole 132.
[0044] In this way, on the one hand, it can prevent the lumped materials from staying above the static plate 131 for a long time, causing accumulation and blockage. On the other hand, it can also prevent the materials that have become larger in volume due to lumping from directly falling onto the conveyor belt and causing a large impact on the conveyor belt.
[0045] In addition, in order to make the materials fall as soon as possible and prevent material accumulation, the fixed grille plate of the traditional discharge port usually is equipped with a vibration motor to make the fixed grille vibrate frequently. However, this kind of vibration will damage the stability of the device. And in this device, through the rotating dynamic plate 141, the material falling speed can be increased to prevent accumulation, replacing the vibration motor, thereby ensuring the stability of the device and preventing damage to the device caused by frequent vibration.
[0046] In summary, by rotating the dynamic plate 141, the static hole 132 and the dynamic hole 143 can be frequently staggered, effectively preventing vertically falling long and hard objects from piercing through and damaging the conveyor belt. In addition, for caked bulk materials, the rotating dynamic plate 141 can also frequently rub against the top surface of the static plate 131, thereby reducing the volume of the caked materials, preventing accumulation and blockage, and protecting the conveyor belt from the impact of large-volume materials falling directly. Moreover, the rotating dynamic plate 141 can accelerate the falling of materials, replacing the traditional solution using a vibration motor and preventing the device from being damaged due to vibration.
[0047] Referring to Figure 1 , this embodiment provides a discharging device, which is characterized in that it includes a protection mechanism, and also includes
[0048] a conveying component 21 arranged outside the discharging component 11, a turning component 22 arranged outside the conveying component 21, and a material receiving component 23 arranged outside the turning component 22.
[0049] The conveying component 21 includes a conveyor belt 211 arranged at the bottom of the discharging hopper 111, and a second support column 212 adaptively installed outside the conveyor belt 211.
[0050] The turning component 22 includes a third support column 221 arranged outside the conveyor belt 211, a rotating shaft 222 rotatably connected to the outside of the third support column 221, and a grid plate 223 fixedly connected to the outside of the rotating shaft 222.
[0051] When the long and hard object is blocked by the dynamic plate 141 and rolls down, it can fall onto the grid plate 223. The staff can drive the rotating shaft 222 to drive the grid plate 223 to rotate by means of motor drive or manual operation, etc., so as to remove the long and hard object.
[0052] As an embodiment provided in the present application, as Figure 1 , the material receiving component 23 includes a material receiving box 231 arranged outside the grid plate 223, and a cover plate 232 hinged to the outside of the material receiving box 231.
[0053] Since the dynamic plate 141 and the static plate 131 are inclined, in addition to long and hard objects, some bulk materials will also roll down along the inclined plane. At this time, the materials mixed with hard objects will fall on the grid plate 223, and the materials directly fall into the material receiving box 231 through the grid plate 223, while the hard objects will be removed by the rotating grid plate 223.
[0054] When the material in the material receiving box 231 is full, the material in the material receiving box 231 can be poured onto the conveyor belt 211 and transported by the conveyor belt 211.
[0055] In summary, through the mutual cooperation between the flipping component 22 and the material receiving component 23, the scattered materials can be distinguished from hard objects, preventing hard objects from still being mixed in the materials and affecting the quality of the materials.
[0056] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
