Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and specifically to a self-engaging segmented belt press for a belt press conveyor. Background Technology

[0002] Press belt conveyors are commonly used for long-distance transportation, especially in open-pit coal mining, to transport raw coal. They can effectively solve the problems of high transportation costs and low continuous operation capacity when using large mine cars. They mainly consist of a material-bearing belt and a cover belt, which confine the transported material between the two belts.

[0003] However, existing belt conveyors have the following problems in use:

[0004] First, due to the drop in elevation in open-pit coal mines, the installation of belt conveyors involves large end-side angles and frequent angle changes, resulting in multiple climbing sections for the belt conveyor. In this way, the fit between the carrying belt and the cover belt changes frequently when the coal is subjected to gravity changes, causing sealing problems and resulting in leakage of the conveyed coal.

[0005] Secondly, the existing method of bonding the carrier belt and the cover belt together with pressure rollers, where the pressure rollers are set at different angles, apply pressure to the inclined carrier belt and cover belt, which causes the internal material to be scraped towards the rear end, thus affecting the conveying capacity.

[0006] In addition, due to frequent angle changes, belt wear often occurs during conveying. The existing methods of replacing the belt or replacing the pressure belt are costly and cumbersome. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention proposes a self-engaging segmented belt pressing type for a belt pressing conveyor.

[0008] The technical solution of the present invention is implemented as follows: a self-engaging segmented belt pressing mechanism for a belt pressing conveyor includes a conveyor belt mechanism and a pressing belt mechanism, wherein the conveyor belt mechanism and the pressing belt mechanism abut against each other, and the pressing belt mechanism includes multiple segmented belts, each segmented belt having a female end and a male end, the female end and the male end being arranged along the width direction of the segmented belt, and the female end and the male end of two adjacent segmented belts being detachably connected;

[0009] A decoupling mechanism is provided on one side of the female end along the width direction. The decoupling mechanism includes a tightening part and a releasing part. The tightening part is used to strengthen the connection between the male end and the female end, and the releasing part is used to lock the male end and the female end.

[0010] The biting band is distributed along the length of the segmented belt on both the front and rear sides of the segmented belt near the conveyor belt mechanism, and the biting band is clamped to the outer side of the conveyor belt on the conveyor mechanism;

[0011] The segmented belt also includes a covering portion and a flexible hollow portion. The covering portion is used to compress the material on the conveyor belt. The flexible hollow portion is located on both sides of the covering portion. The inner cavity of the flexible hollow portion is connected to the inner cavity of the clamping belt. When the flexible hollow portion contacts the conveyor belt, the clamping belt locks the conveyor belt along the width direction.

[0012] Furthermore, the conveyor belt is provided with a thickened edge along its length edge, one side of the gripping belt contacts the thickened edge, and is provided with a receiving groove that can accommodate the thickened edge.

[0013] Further, the female end includes a positioning component and a locking rod, and the female end is provided with a first groove and a second groove for adapting to the positioning component and the locking rod. A locking seat for locking the positioning component and a reverse-prevention component for locking the locking rod are provided in the first groove and the second groove, wherein:

[0014] The positioning part includes two opposing hanging ears. The inner side of the hanging ears is provided with an arc-shaped protrusion, the surface of the arc-shaped protrusion is provided with a guide bead, and a concave surface is provided near the position of the arc-shaped protrusion.

[0015] Furthermore, the decoupling mechanism includes a strip-shaped cavity, with a first limiting block and a second limiting block respectively disposed on both sides of the inner cavity of the strip-shaped cavity. The first limiting block and the second limiting block are arranged opposite to each other. One end of the tightening part is elastically disposed inside the first limiting block, and the other end of the tightening part passes through the second limiting block and is adjustable on the second limiting block. One end of the releasing part is elastically disposed inside the second limiting block, and the other end of the releasing part passes through the first limiting block and is adjustable on the first limiting block. Both the tightening part and the releasing part are pull ropes. The releasing part is connected to the anti-reverse component through two branch rope ends, and the tightening part is connected to the positioning component through one branch rope end.

[0016] Furthermore, the clamping band includes a lateral restraint portion and a gripping portion. The lateral restraint portion is fitted to the outer side of the conveyor belt. The gripping portion includes a connecting seat connected to the two lateral restraint portions. The connecting seat is provided with a pressure-gathering chamber that communicates with the inner cavity of the flexible hollow portion. A horizontal push plate is provided in the pressure-gathering chamber. When the pressure in the pressure-gathering chamber increases, the horizontal push plate moves outward. A clamping block is hinged to the outer side of the horizontal push plate. The inner side of the horizontal push plate is elastically connected to one side of the inner wall of the pressure-gathering chamber through an elastic rope.

[0017] Furthermore, the anti-reverse component includes a tapered sleeve, the tapered tip of which is provided with a locking groove adapted to the inner diameter of the locking rod, a locking head is provided on the outer side of the inner cavity of the tapered sleeve, a limiting sleeve is provided on the inner side of the inner cavity of the tapered sleeve, the limiting sleeve is sleeved on the end of the locking rod, and a limiting ring is provided between the limiting sleeve and the locking head.

[0018] Furthermore, the locking head includes a frustum sleeve, the inner wall of which is provided with circular grooves at equal intervals, the inner wall of which is provided with an oblique guide groove, a retaining bead is fitted at the circular groove of the oblique guide groove, the surface of the retaining bead is elastically connected to the inner wall of the circular groove through an elastic strip, the surface of the retaining bead abuts against the retaining rod, and a connecting rope is fixedly connected to the other side of the surface of the retaining bead, the two ends of the release part are fixedly connected to one side of the limiting ring, and the other end of the connecting rope is fixedly connected to the other side of the limiting ring.

[0019] Furthermore, the clamping seat includes a U-shaped centering plate, a vase groove is provided in the middle of the U-shaped centering plate, a flexible compression deformation sleeve adapted to the shape of the vase groove edge is fitted inside the vase groove, the two ends of the flexible compression deformation sleeve are fixedly connected to one side of the inner wall of the vase groove through a connecting layer, magnetic suction plates are embedded in corresponding positions on both sides of the inner wall of the flexible compression deformation sleeve, a movable ball is fitted inside the flexible compression deformation sleeve, the movable ball is fixedly connected to the rope end of the tightening part, and the rope end passes through the opening provided in the U-shaped centering plate.

[0020] Furthermore, a locking channel is provided between the inner cavity of the flexible hollow portion and the pressure-gathering cavity, and the locking channel has two opposing arc-shaped strips with their outer convex surfaces in contact.

[0021] The present invention has the following beneficial effects:

[0022] 1. When the clamping rod of the present invention enters the conical sleeve, on the one hand, the limiting sleeve and the clamping rod groove keep the clamping rod in a straight state within the anti-reverse component, and also keep the two ends of the clamping rod in a restricted state, thereby maintaining the flatness of the belt surface and facilitating transmission. On the other hand, when the clamping rod and the clamping head move in opposite directions, the clamping head can clamp the clamping rod to prevent the phenomenon of the rod coming off. Moreover, when the segmented belt is squeezed by the pressure roller group, the segmented belt can bend along the width direction, so that the pressure belt can stably press the material and adapt to the shape of the material surface.

[0023] 2. When the clamping rod of the present invention enters the inner cavity of the frustum sleeve, the entry end of the clamping rod is provided with a chamfered surface. When inserted into the inner cavity of the frustum sleeve, the chamfered surface contacts the surface of the three clamping beads arranged at equal intervals inside the frustum sleeve. Utilizing the guiding effect of the inclined surface, the chamfered surface enables the three clamping beads to move radially, thereby allowing the clamping beads to enter the inclined guide groove from the circular groove. This ensures that the clamping rod is stably inserted into the frustum sleeve. After insertion, due to the setting of the inclined guide groove, when the clamping rod moves in the opposite direction, the surface of the clamping rod contacts the surface of the clamping beads. When it is restricted by the elastic strip pull and the inner wall of the circular groove, the friction generated by the contact enables the clamping beads to move in the opposite direction to the inclined guide groove. Thus, under the action of the external pulling force of the clamping rod, the clamping beads can lock the clamping rod in place. As the pulling force increases, the locking effect is better.

[0024] 3. The positioning part and clamping seat of the present invention are set so that when the positioning part is inserted into the slot one, the magnetic suction plate will attract the movable ball. On the one hand, when the hanging ear is inserted, the movable ball is located in the middle position, which can provide enough space so that when the hanging ear squeezes the outside of the flexible compression deformation sleeve, the flexible compression deformation sleeve has enough deformation position, thereby ensuring that the arc protrusion on the hanging ear moves to the bottleneck position of the flexible compression deformation sleeve.

[0025] 4. The guide bead of the present invention has a track groove on the path of movement of the guide bead. The track groove can facilitate positioning operation, reduce friction, facilitate the entry of the lug, and prevent the lug from contacting the outer side of the flexible compression deformation sleeve when it enters, which would cause the deformation position to be incorrect and the entry to be blocked.

[0026] 5. After the segmented belts are spliced, the pull rod on the tightening part is pulled out from the inside of the limiting sleeve. After tightening the nut, one end of the pull rod can be extended out. In this way, the tightening part can drive the movable ball to move towards the bottleneck position and support both sides of the inner wall of the flexible compression deformation sleeve. This prevents the hanging ear from detaching from the bottleneck of the flexible compression deformation sleeve, thereby increasing the firmness of the segmented belt splicing. Conversely, when the pull rod is loosened, the movable ball can move to the middle of the inner cavity of the flexible compression deformation sleeve through the elastic rope and magnetic plate, so that the hanging ear can detach from the flexible compression deformation sleeve.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1The self-engaging segmented belt pressing mechanism of the belt pressing conveyor shown includes a conveyor belt mechanism 2 and a pressing belt mechanism 1. The conveyor belt mechanism 2 and the pressing belt mechanism 1 are mounted on a conveyor frame and abut against each other. The pressing belt mechanism 1 includes multiple segmented belts 4, each segmented belt 4 having a female end 7 and a female end 8. The female end 7 and the female end 8 are arranged along the width direction of the segmented belt 4. The female end 7 and the female end 8 of two adjacent segmented belts 4 are detachably connected. A pressure roller group 3 is provided at the contact point between the conveyor belt mechanism 2 and the pressing belt mechanism 1 near the middle of the segmented belts 4. The pressure roller group 3 makes the segmented belts 4 engage with the conveyor belt mechanism 2. A disintegration roller 301 is provided near the thickened position 201 at the separation position between the conveyor belt mechanism 2 and the pressing belt mechanism 1. When the disintegration roller 301 presses on the edge of the segmented belt 4, it can separate the segmented belt 4 from the conveyor belt from the engaged state. Both the pressure roller group 3 and the disintegration roller 301 are mounted on the conveyor frame.

[0043] See Figure 2 , Figure 9 , Figure 10 and Figure 11 The female end 7 shown has a slot 1 701 and a slot 2 702 for adapting to the positioning component and the locking rod 801. The slot 1 701 and the slot 2 702 are provided with a locking seat for locking the positioning component and a backstop component for locking the locking rod 801. The male end includes the positioning component and the locking rod.

[0044] When the two segmented belts 4 are installed, the positioning component is inserted into slot 1 701 and can be locked onto the clamping seat. When the clamping rod 801 enters slot 2 702, it can be inserted into the anti-reverse component. This allows for quick positioning. The multiple clamping rods 801 and anti-reverse components are connected to the segmented belts 4 by rope connection. Specifically, the shaft of the clamping rod 801 is fixed to the rope end or wire end that is pre-reserved on the exposed side inside the segmented belt 4. After this connection, the installation ends of the two segmented belts 4 have better deformability and flexibility, and achieve better adaptation when passing through the conveyor roller. The positioning component also adopts this method, which makes the conveying effect more stable and avoids damage to the entire belt.

[0045] See Figure 9 and Figure 10 The anti-reverse component shown includes a tapered sleeve 7021. The tapered tip of the tapered sleeve 7021 is provided with a locking groove that matches the inner diameter of the locking rod 801. A locking head is provided on the outer side of the inner cavity of the tapered sleeve 7021. A limiting sleeve 7024 is provided on the inner side of the inner cavity of the tapered sleeve 7021. The limiting sleeve 7024 is sleeved on the end of the locking rod 801. A limiting ring 7023 is provided between the limiting sleeve 7024 and the locking head.

[0046] When the clamping rod 801 enters the conical sleeve 7021, on the one hand, the limiting sleeve 7024 and the clamping rod groove keep the clamping rod 801 in a straight position within the anti-reverse component, and also keep both ends of the clamping rod 801 in a restricted state, thereby maintaining the flatness of the belt surface and facilitating transmission. On the other hand, when the clamping rod 801 moves in opposite directions to the clamping head, the clamping head can clamp the clamping rod 801 to prevent the rod from coming off. Moreover, when the segmented belt 4 is squeezed by the pressure roller group 3, the segmented belt 4 can bend along the width direction, so that the pressure belt can stably press the material and adapt to the shape of the material surface.

[0047] See Figure 11 The locking head shown includes a frustum sleeve 7022. Circular grooves 7025 are evenly spaced on the inner wall of the frustum sleeve 7022. An oblique guide groove 7026 is provided on the inner wall of each circular groove 7025. A retaining bead 7028 is fitted into the oblique guide groove 7026 at the location of the circular groove 7025. The surface of the retaining bead 7028 is elastically connected to the inner wall of the circular groove 7025 via an elastic strip, ensuring that one side of the retaining bead 7028 is always exposed outside the circular groove 7025 under the elastic action of the elastic strip and remains on the path of the moving lever 801. The oblique guide groove 7026 serves as the retaining bead 7028. 28 provides a space for movement. When the locking ball 7028 is pulled outward, the locking ball 7028 enters the inclined guide groove 7026, and the exposed part can enter the circular groove 7025, thereby enabling the locking ball 7028 to disengage from the locking rod 801. The surface of the locking ball 7028 abuts against the locking rod 801. A connecting rope is fixedly connected to the other side of the surface of the locking ball 7028. The two ends of the release part are fixedly connected to one side of the limiting ring 7023, and the other end of the connecting rope is fixedly connected to the other side of the limiting ring 7023.

[0048] When the locking rod 801 enters the inner cavity of the frustum sleeve 7022, the entry end of the locking rod 801 is provided with a chamfered surface. When inserted into the inner cavity of the frustum sleeve 7022, the chamfered surface contacts the surface of the three locking beads 7028 that are equidistantly arranged inside the frustum sleeve 7022. Utilizing the guiding effect of the inclined surface, the chamfered surface allows the three locking beads 7028 to move radially, thereby enabling the locking beads 7028 to enter the inclined guide groove 7026 from the circular groove 7025. This ensures that the locking rod 801 is stably inserted into the frustum sleeve 7022. Within 2, after insertion is completed, due to the setting of the inclined guide groove 7026, when the locking rod 801 moves in the opposite direction, the surface of the locking rod 801 comes into contact with the surface of the locking ball 7028. When it is restricted by the elastic strip pull and the inner wall of the circular groove 7025, the friction generated by the contact can make the locking ball 7028 move in the opposite direction to the inclined guide groove 7026. Thus, the locking ball 7028 can lock the locking rod 801 under the action of the external pulling force of the locking rod 801. As the pulling force increases, the locking effect is better.

[0049] The advantages of the above setup are that it facilitates the replacement of segment belt 4, and as the material on the conveyor belt increases, the pressure on the belt gradually tightens, which improves the firmness of the connection and prevents the belt from becoming taut. Moreover, the replacement operation is convenient and can be quickly performed based on the damage point.

[0050] See Figure 6 The positioning part shown includes two opposing hanging ears 802. An arc-shaped protrusion 803 is provided on the inner side of each hanging ear 802. A guide bead 804 is provided on the surface of the arc-shaped protrusion 803. A concave surface is provided near the arc-shaped protrusion 803. The clamping seat includes a U-shaped centering plate 7011. A vase groove 7012 is formed in the center of the U-shaped centering plate 7011. A flexible compression deformation sleeve 7013, adapted to the edge shape of the vase groove 7012, is fitted inside the vase groove 7012. Both ends of the sleeve 7013 are fixedly connected to one side of the inner wall of the vase groove 7012 through the connecting layer. Magnetic plates 7014 are embedded in the corresponding positions on both sides of the inner wall of the flexible compression deformation sleeve 7013. A movable ball 7015 is installed inside the flexible compression deformation sleeve 7013. The movable ball 7015 is elastically connected to one side of the inner wall of the flexible compression deformation sleeve 7013 through an elastic rope. The movable ball 7015 is fixedly connected to the rope-branching end of the tightening part 501, and the rope-branching end passes through the opening on the U-shaped centering plate 7011.

[0051] The positioning part and the clamping seat are set so that the positioning part is inserted into the slot 701 and the magnetic suction plate 7014 attracts the movable ball 7015. On the one hand, when the hanging ear 802 enters, the movable ball 7015 is in the middle position, which can provide enough space so that when the hanging ear 802 squeezes the outside of the flexible compression deformation sleeve 7013, the flexible compression deformation sleeve 7013 has enough deformation position, thereby ensuring that the arc protrusion 803 on the hanging ear 802 moves to the bottleneck position of the flexible compression deformation sleeve 7013.

[0052] The guide bead 804 has a track groove on its moving path, which facilitates positioning operation, reduces friction, facilitates the entry of the lug 802, and prevents the lug 802 from contacting the outer side of the flexible compression deformation sleeve 7013 when it enters, thus avoiding incorrect deformation position and obstruction of entry.

[0053] The two ends of the flexible compression deformation sleeve 7013 are fixedly connected to one side of the inner wall of the vase groove 7012 through the connecting layer. The connection is located at the bottleneck of the vase groove 7012. When the two sides of the flexible compression deformation sleeve 7013 are squeezed, the flexible compression deformation sleeve 7013 narrows, which allows the flexible compression deformation sleeve 7013 to be compressed into a state that allows the hanging ear 802 to enter. When the arc protrusion 803 enters, the upper and lower positions of the two sides of the flexible compression deformation sleeve 7013 are squeezed at the same time. Moreover, when the arc protrusion 803 moves to the bottleneck position, the flexible compression deformation sleeve 7013 can return to its original shape, so that the hanging ear 802 and the flexible compression deformation sleeve 7013 are adapted to each other.

[0054] The flexible compression deformation sleeve 7013 and the movable ball 7015 cooperate with each other. After installation, the decoupling mechanism can move the movable ball 7015 to the inside of the bottleneck, thereby preventing the flexible compression deformation sleeve 7013 from being deformed by pressure. This ensures that the lug 802 and the flexible compression deformation sleeve 7013 are locked together.

[0055] See Figure 2 , Figure 3 and Figure 12 The decoupling mechanism 5 shown is disposed on one side of the female end 7 along the width direction. The decoupling mechanism 5 includes a tightening portion 501 and a releasing portion 502. The tightening portion 501 is used to strengthen the connection between the male end 8 and the female end 7, and the releasing portion 502 is used to clamp the male end 8 and the female end 7. The decoupling mechanism 5 includes a strip-shaped cavity. A first limiting block 503 and a second limiting block 504 are respectively disposed on both sides of the inner cavity of the strip-shaped cavity. The first limiting block 503 and the second limiting block 504 are arranged opposite to each other. One end of the tightening portion 501 is elastically disposed... The other end of the tightening part 501 passes through the second limiting block 504 and is adjustable on the second limiting block 504. One end of the releasing part 502 is elastically disposed inside the second limiting block 505, and the other end of the releasing part 502 passes through the first limiting block 503 and is adjustable on the first limiting block 503. Both the tightening part 501 and the releasing part 502 are pull ropes. The releasing part 502 is connected to the anti-reverse component through two branch rope ends, and the tightening part 501 is connected to the positioning component through one branch rope end.

[0056] The opposite ends of the tightening part 501 and the releasing part 502 are elastically connected to the first limiting block 503 and the second limiting block 504 respectively via elastic ropes 505. A pull rod 507 is provided at the through end of the tightening part 501 and the releasing part 502. A limiting sleeve 506 is sleeved on the pull rod 507. The two limiting sleeves 506 are fixedly connected to the first limiting block 503 and the second limiting block 504 respectively.

[0057] After the segmented belt 4 is spliced, by pulling the lever 507 on the tightening part 501, the lever 507 is pulled out from inside the limiting sleeve 506 to the outside. After tightening the nut, the nut allows one end of the lever 507 to extend out. In this way, the tightening part 501 can drive the movable ball 7015 to move towards the bottleneck position and support the two sides of the inner wall of the flexible compression deformation sleeve 7013. In this way, the hanging ear 802 cannot detach from the bottleneck of the flexible compression deformation sleeve 7013, thereby increasing the firmness of the splicing of the segmented belt 4. Conversely, when the lever 507 is loosened, the movable ball 7015 can move to the middle of the inner cavity of the flexible compression deformation sleeve 7013 through the elastic rope and the magnetic suction plate 7014, so that the hanging ear 802 can detach from the flexible compression deformation sleeve 7013.

[0058] When the pull rod 507 on the release part 502 is pulled outward, the locking ball 7028 in the locking head is pulled into the inclined guide groove 7026, so that the locking ball 7028 can disengage from the surface of the locking rod 801, thereby achieving the purpose of belt separation.

[0059] See Figure 2 , Figure 13 and Figure 14 The clamping band 6 shown is distributed along the length of the segmented belt 4 on both the front and rear sides of the segmented belt 4 near the conveyor belt mechanism 2. The clamping band 6 is clamped to the outer side of the conveyor belt on the conveyor mechanism 2. The segmented belt 4 also includes a covering portion 401 and a flexible hollow portion 402. The covering portion 401 is used to compress the material on the conveyor belt. The flexible hollow portion 402 is distributed on both sides of the covering portion 401. The inner cavity of the flexible hollow portion 402 is connected to the inner cavity of the clamping band 6. When the flexible hollow portion 402 contacts the conveyor belt, the clamping band 6 locks the conveyor belt along the width direction (the covering portion and the flexible hollow portion are integrally formed). The male and female ends are respectively located on both sides of the covering part and the flexible hollow part. The flexible hollow part is equipped with a pressure chamber. When the belt is pressed, the internal air pressure can be concentrated into the inner cavity of the gripping belt. The covering part 401 contacts the material on the conveyor belt and forms a sealed space with the conveyor belt. In this way, when the material is conveyed, the stability of the conveyed material during the lifting process can be guaranteed, and there will be no problem of material falling. In addition, when the conveyor roller is conveyed, due to the locked state, the conveyor belt and the pressure belt in the height direction on both sides can be guaranteed to avoid the problem of overall misalignment. Moreover, after the pressure belt is pressed, there will be no problem of loose belt within the length of the conveyor belt.

[0060] The conveyor belt has a thickened edge 201 along its length edge. One side of the clamping belt 6 contacts the thickened edge 201 and is provided with a receiving groove to accommodate the thickened edge. On the one hand, when the pressure roller group 3 presses on the surface of the segmented belt 4, the segmented belt 4, which is squeezed, can form an abutment state with the conveyor belt 2. Due to the setting of the clamping belt 6, the clamping belt 6 can form a clamping state with the thickened edge 201 along the vertical side of the thickened edge 201. Thus, the clamping belt 6 can wrap the thickened edge 201. The receiving groove is used to restrict the thickened edge 201. During horizontal conveying, it can ensure that the interior is in a closed state.

[0061] See Figure 2 and Figure 4 The shown gripping belt includes a lateral restraint portion 601 and a gripping portion 602. The lateral restraint portion 601 is attached to the outer side of the conveyor belt. The gripping portion 602 includes a connecting seat 6021 connected to the two lateral restraint portions 601. A pressure-gathering chamber 6022 communicating with the inner cavity of the flexible hollow portion 402 is provided in the connecting seat 6021. A horizontal push plate 6023 is provided in the pressure-gathering chamber 6022. When the pressure in the pressure-gathering chamber 6022 increases, the horizontal push plate 6023 moves outward. A clamping block 6024 is hinged to the outer side of the horizontal push plate 6023. The inner side of the horizontal push plate 6023 is elastically connected to one side of the inner wall of the pressure-gathering chamber 6022 through an elastic rope.

[0062] When the thickened edge 201 contacts the lateral limiting part 601, the receiving groove provided in the lateral limiting part 601 can lock the thickened edge 201. During the conveying process, the pressure belt is squeezed by the pressure roller group 3. The squeezing point is located on the surface of the flexible hollow part 402, which causes the air pressure in the flexible hollow part 402 to enter the pressure-gathering chamber 6022. The air pressure inside the pressure-gathering chamber 6022 increases, which can cause the horizontal push plate 6023 to move outward. In this way, the horizontal push plate 6023 can move to the bottom of the thickened edge 201. Thus, when there is a separation force on the pressure belt, it can always maintain a locked state under the clamping of the clamping block 6024, which can increase the stability of material conveying.

[0063] See Figure 4 and Figure 5 As shown, a locking channel 4051 is provided between the inner cavity of the flexible hollow portion 402 and the pressure-gathering cavity 6022. The locking channel 4051 has two opposing arc-shaped strips 4053, with their convex surfaces in contact. The arc-shaped strips 4053 are fixedly connected to the inner wall of the locking channel 4051 through the airbag layer 4052. The flexible hollow portion 402 and the covering portion 401 are fixedly connected through a flexible connecting layer 403. The inner cavity of the flexible hollow portion 402 is provided with a pressure medium 404.

[0064] The flexible connecting layer 403 has several advantages. First, when the covering part 401 covers the material, the state of the flexible connecting layer 403 can be adaptively adjusted according to the height of the material pile on the conveyor belt. Second, when it contacts and presses against the thickened edge 201, it can quickly lock the thickened edge 201 in place. Third, when the pressure roller group 3 presses against the flexible hollow part 402, the flexible hollow part 402 can achieve a fully fitted state according to the inclination of the conveyor belt. The pressure medium 404 is located inside the flexible hollow part 402. Inside the cavity, when squeezed by the pressure roller group 3, the pressure medium 404 in the flexible hollow part 402 is squeezed and enters the locking channel 4051, and squeezes the two contacting arc strips 4053. Under the impact of the fluid, the two arc strips 4053 move back to back to form a channel, and the pressure medium 404 can flow into the pressure-gathering cavity 6022, which can then apply pressure to the inner side of the horizontal push plate 6023, so that the horizontal push plate 6023 can move out and clamp the thickened edge 201.

[0065] When the conveyor belt separates from the clamping band 6 on the segmented belt 4, the disintegration roller 301 squeezes the belt surface above the clamping band 6. As a result, the side of the arc strip 4053 away from the flexible hollow part 402 is squeezed, and the internal pressure medium 404 enters the flexible hollow part 402. The pressure inside the pressure chamber 6022 decreases, and the clamping block 6024 can be restored under the pull of the elastic band. In this way, the clamping block 6024 can be separated from the thickened edge 201.

[0066] The locking channel 4051 allows the gas inside the airbag layer 4052 to change freely. When fluid passes through, it causes the surfaces of the two originally attached arc-shaped strips 4053 to be subjected to compressive force. When the arc-shaped strips 4053 are attached, under normal conditions, they can seal the space on both sides. When compressed, the arc-shaped strips 4053 can cause the airbag layer 4052 to be stressed, thus forming a gap between the arc-shaped strips 4053 to allow the pressure medium 404 to pass through, thereby achieving the purpose of pressure exchange. In addition, when the flexible hollow part 402 is inclined and attached to the inner wall of the conveyor belt, the air pressure inside the two airbag layers 4052 can cause the two arc-shaped strips 4053 to be in an inclined state. The two arc-shaped strips 4053 are always in contact, so that the locking channel 4051 is always in a closed state, thereby increasing the stability and firmness of the conveyor belt during transmission.

[0067] During the conveying process of the segmented belt 4, the conveyor rollers make adaptive adjustments according to the conveyor belt. The covered part 401 contacts the roller surface of the conveyor rollers, while the flexible hollow part 402 does not contact the roller surface of the conveyor rollers.

[0068] It should be noted that the pressure medium 404 can be either a gas or a liquid.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
