The above device adopts a stepped separation sleeve structure, so that the larger diameter part of the stepped separation sleeve has a separation effect on the chain plate, and the smaller diameter part of the stepped separation sleeve is slidably connected with the inner hole of the chain plate to transmit force, which effectively increases the rigidity of the chain shaft, improves the force condition of the chain shaft, and reduces the wear of the chain shaft. However, the above device has the following technical problems when used: 1. Incomplete cleaning of debris: During the operation of the existing force transmission conveyor chain, debris is easily accumulated on the chain belt, making it difficult to clean efficiently; 2. Poor operation stability of the chain belt: The chain belt is prone to deviation and chain drop during operation. Due to the lack of an effective limiting structure, external blockages can easily enter the joint between the chain belt and the sprocket, causing the chain belt to deform. At the same time, when the chain belt is impacted by external forces or partially deformed, it is not supported and restrained in time; Based on this, the present invention provides a whole-shaft sleeve force transmission conveying chain to solve the problems raised in the above background technology. Summary of the invention

[0005] Based on the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the sprocket group includes a driving sprocket member and three driven sprocket members, and the driving sprocket member and the driven sprocket member both include a transmission shaft rotatably connected to the frame and a chain shaft rotatably connected to the conveying frame, the inner wall of the chain shaft is rotatably connected to a cleaning shaft, and the interior of the cleaning shaft is fixedly provided with an axis groove with a tail end opening and slidably connected to the transmission shaft, and the cross-sections of the axis groove and the transmission shaft are both regular hexagons, a sprocket that fits the chain belt is fixedly installed on the chain shaft, and a pulley that fits the cleaning belt is fixedly installed on the cleaning shaft.

[0007] The beneficial effect of adopting the above-mentioned further scheme is that, when in use, the regular hexagonal design enables the transmission shaft to drive the cleaning shaft to rotate synchronously and slide relatively within a certain range. It is easy to install and has a stable connection. When working, the rotation of the transmission shaft drives the sprocket on the chain shaft to rotate, thereby driving the chain belt to run, and at the same time drives the cleaning shaft to rotate, so that the pulley on the cleaning shaft drives the cleaning belt to rotate, realizing the rotation of the chain belt and the cleaning belt, and when the chain belt and the cleaning belt rotate, the chain belt and the cleaning belt are in a differential rotation state. Through the above-mentioned state setting, it is ensured that the cleaning belt is always used for cleaning during the operation of the chain belt, avoiding the accumulation of debris on the chain belt and blocking the chain belt, thereby reducing the chain belt failure caused by the blockage of debris.

[0008] Furthermore, two stop wheels are rotatably mounted on the conveying frame corresponding to each cleaning shaft, and the two stop wheels are both in contact with the chain belt.

[0009] The beneficial effect of adopting the above further scheme is that when the chain belt is in use and is driven by the sprocket group, the two blocking wheels, on the one hand, limit the chain belt to prevent the chain belt from deviating during operation, and on the other hand, can effectively reduce the probability of external blockages entering the joint between the chain belt and the sprocket, thereby reducing the deformation of the chain belt caused by the entry of debris and the chain belt escaping rate; At the same time, when the chain belt is impacted by external force or has local deformation, the retaining wheel can provide timely support and restraint to the chain belt to prevent the chain belt from falling off due to displacement or excessive deformation, thus solving the technical problem that the chain belt is prone to falling off due to deformation or displacement. The outstanding beneficial effect is to improve the stability of the chain belt operation, reduce the occurrence of chain falling failures, and extend the service life of the chain belt.

[0010] Furthermore, the sprocket group also includes a differential shaft rotatably connected to the conveying frame, and a first differential bevel tooth is installed on the chain shaft and the differential shaft on the driving sprocket member, and the two first differential bevel teeth are meshed with each other. A second differential bevel tooth is installed on the cleaning shaft and the differential shaft on the driving sprocket member, and the two second differential bevel teeth are meshed with each other.

[0011] The beneficial effect of adopting the above further scheme is that when the chain shaft of the active sprocket rotates, the first differential bevel teeth on the chain shaft drive the first differential bevel teeth on the differential shaft to rotate, thereby causing the differential shaft to rotate, and the second differential bevel teeth on the differential shaft drive the second differential bevel teeth on the cleaning shaft of the active sprocket to rotate, thereby realizing differential transmission of the chain shaft and the cleaning shaft, ensuring that the cleaning belt rotation speed is 1.5 times the chain belt rotation speed, solving the problem of the difficulty in accurately controlling the speed difference between the chain belt and the cleaning belt in the prior art, and the outstanding beneficial effect is to ensure that the cleaning belt can more efficiently clean the debris on the chain belt, avoid the debris residue from clogging the chain belt, and improve the cleaning effect; When in use, the cleaning shaft on the driving sprocket is connected to a power input device of an external machine, and the other three cleaning shafts are all connected to a power output device.

[0012] Furthermore, the vibration transmission mechanism includes two belt shafts and two first cam shafts rotatably connected to the frame, one of the belt shafts is connected to the transmission shaft through a first belt, a second belt is connected between the two belt shafts, a first eccentric wheel is installed on each of the two first cam shafts, the two first eccentric wheels are fitted with the conveying frame, the axis of the first cam shaft is perpendicular to the axis of the transmission shaft, a first bevel gear is installed on the top of the two first cam shafts, a second bevel gear is installed at the tail end of the two belt shafts, the two first bevel gears are respectively connected to the two second bevel gears, and a group of elastic reset parts are installed between the conveying frame and the frame.

[0013] The beneficial effect of adopting the above further scheme is that when in use, the transmission shaft rotates through the first belt to drive a belt shaft to rotate, and the belt shaft then drives another belt shaft to rotate through the second belt, and at the same time, the second bevel gear on the belt shaft drives the first bevel gear on the first convex shaft to rotate, so that the first convex shaft rotates, and the first eccentric wheel on the first convex shaft continuously squeezes the conveying frame as it rotates, so that the conveying frame reciprocates left and right, and the elastic reset member plays a role of buffering and resetting; The reciprocating movement of the conveyor frame can cause the chain belt to vibrate to a certain extent during operation, shaking off the debris attached to the chain belt, solving the problem that the chain belt is easily attached to debris and blocked by debris. The outstanding beneficial effect is to use vibration to assist in cleaning the chain belt, enhance the cleaning effect, and reduce the frequency of manual cleaning.

[0014] Furthermore, the elastic reset member includes a T-shaped guide rod installed on the back of the conveying frame, the T-shaped guide rod is slidably connected to the frame, and a reset spring limited by the frame is sleeved on the T-shaped guide rod.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that when in use, when the first eccentric wheel squeezes the conveyor frame to make the conveyor frame move to the left or right, the T-shaped guide rod slides on the frame and the reset spring is compressed. When the first eccentric wheel no longer squeezes the conveyor frame, the reset spring releases the elastic force to push the conveyor frame to reset, thereby ensuring that the conveyor frame can stably move back and forth left and right, avoiding the conveyor frame from affecting the vibration cleaning effect of the chain belt due to excessive movement or inability to reset, and solving the problem of unstable movement of the conveyor frame in the vibration transmission mechanism. The outstanding beneficial effect is to ensure that the vibration transmission mechanism continues to work stably, thereby effectively cleaning the chain belt debris and maintaining the normal operation of the chain belt.

[0016] Furthermore, the shaking drive mechanism includes a square shaft rotatably connected to the frame and a second cam shaft rotatably connected to the conveying shaft, the square shaft is connected to the second belt transmission, the interior of the square shaft is fixedly provided with a square groove with a tail end opening and slidably connected to the second cam shaft, the cross-sections of the square groove and the second cam shaft are both regular hexagons, a second eccentric wheel is installed on the second cam shaft, an I-shaped wheel is rotatably installed on the shaking seat, the second eccentric wheel is in contact with the I-shaped wheel, and the second cam shaft is arranged parallel to the transmission shaft.

[0017] The beneficial effect of adopting the above further scheme is that the square shaft rotates under the drive of the second belt, and the square groove inside the square shaft cooperates with the second cam shaft to rotate the second cam shaft, and the second eccentric wheel on the second cam shaft continuously squeezes the I-shaped wheel on the shaking seat as it rotates, so that the shaking seat moves back and forth up and down, and the inner clamping wheel and the outer clamping wheel on the shaking seat shake accordingly, further shaking off the debris on the chain belt, solving the problem that the debris on the chain belt is difficult to clean thoroughly. The outstanding beneficial effect is that the chain belt is shaken and cleaned from multiple angles, effectively removing stubborn debris on the chain belt, and reducing the risk of the chain belt being blocked by debris and falling off.

[0018] Furthermore, the pneumatic cleaning assembly includes a pump barrel installed on a frame, a pump shaft is rotatably installed on the inner wall of the pump barrel, the pump shaft is connected to the second belt transmission, a group of pump blades distributed in a circular array are installed on the pump shaft and at a position corresponding to the inner side of the pump barrel, a filter element is installed at the air inlet port of the pump shaft, and the air outlet port of the pump shaft is connected to a high-pressure nozzle, two symmetrically arranged air distribution pipes are installed on the conveying frame, and the air outlet ports of the high-pressure nozzles are connected to the inner cavities of the two air distribution pipes through three-way pipes respectively, and each of the air distribution pipes is provided with two symmetrically arranged jet surfaces, which are arranged on the inner side of the chain belt, and each of the jet surfaces is provided with a group of jet holes distributed in a linear array and connected to the inner cavity of the air distribution pipe.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that the pump shaft rotates under the drive of the second belt, and the pump blades on the pump shaft rotate accordingly, sucking air into the pump barrel and compressing it, and ejecting high-pressure gas through the high-pressure nozzle. The high-pressure gas enters the air distribution pipe through the three-way pipe and is then sprayed to the inside of the chain belt from the jet hole, thereby pneumatically cleaning the chain belt and removing fine debris in the gaps of the chain belt, solving the problem of debris inside the chain belt being difficult to clean. The outstanding beneficial effect is that it can clean deeply inside the chain belt, making up for the shortcomings of mechanical cleaning, effectively preventing debris from clogging the chain belt and causing the chain belt to deform, and improving the cleanliness and service life of the chain belt.

[0020] The beneficial effects of the present invention are: 1. The present invention creatively sets up a structure in which the cleaning belt and the chain belt rotate differentially and cooperate with the rubber bristles for cleaning. The rotation speed of the cleaning belt is 1.5 times that of the chain belt. The rubber bristles can continuously clean the debris on the surface of the chain belt. At the same time, the vibration transmission mechanism makes the chain belt vibrate and shake off the debris. The shaking drive mechanism further shakes the chain belt from multiple angles to remove stubborn debris. The pneumatic cleaning component penetrates deep into the chain belt to clean small debris. These collaborative cleaning methods are in sharp contrast to the incomplete cleaning of debris in the prior art. They can comprehensively and efficiently clean the debris on the chain belt, greatly reduce the chain belt failure caused by debris blockage, and significantly improve the cleaning performance and operation reliability of the force transmission conveyor chain.

[0021] 2. In the present invention, the stop wheel arranged on the conveyor frame corresponding to the position of the cleaning shaft is an important innovation of the present invention. On the one hand, the stop wheel limits the chain belt, effectively preventing the chain belt from shifting during operation, reducing the probability of external blockages entering the joint between the chain belt and the sprocket, and reducing the deformation of the chain belt caused by the entry of debris. On the other hand, when the chain belt is impacted by external force or local deformation occurs, the stop wheel can provide support and restraint in time to prevent the chain belt from falling off due to deviation or excessive deformation. This design solves the problem of poor operation stability of the chain belt in the prior art, greatly prolongs the service life of the chain belt, and ensures the stable operation of the force transmission conveyor chain.

[0022] 3. The present invention utilizes the unique design of the differential shaft and two sets of differential bevel gears to achieve precise control of the speed difference between the chain belt and the cleaning belt, ensuring that the cleaning belt speed is 1.5 times that of the chain belt. Compared with the prior art which is difficult to accurately control the speed difference, the present invention can ensure that the cleaning belt can more efficiently clean the debris on the chain belt, avoiding debris residue from clogging the chain belt, effectively improving the cleaning effect of the force transmission conveyor chain, and providing a strong guarantee for the efficient operation of the force transmission conveyor chain.

The driving sprocket member and the driven sprocket member both include a transmission shaft 12 rotatably connected to the frame 1, and a chain shaft 13 rotatably connected to the conveyor frame 2. The inner wall of the chain shaft 13 is rotatably connected to a cleaning shaft 14. The interior of the cleaning shaft 14 is fixedly provided with an axis groove 30 with a tail end opening and slidingly connected to the transmission shaft 12. The cross-sections of the axis groove 30 and the transmission shaft 12 are both regular hexagons. A sprocket that fits the chain belt 3 is fixedly installed on the chain shaft 13, and a pulley that fits the cleaning belt 4 is fixedly installed on the cleaning shaft 14.

[0027] When in use, the regular hexagonal design enables the transmission shaft 12 to drive the cleaning shaft 14 to rotate synchronously and slide relatively within a certain range. It is easy to install and has a stable connection. When working, the transmission shaft 12 rotates to drive the sprocket on the chain shaft 13 to rotate, thereby driving the chain belt 3 to run, and at the same time drives the cleaning shaft 14 to rotate, so that the pulley on the cleaning shaft 14 drives the cleaning belt 4 to rotate, realizing the rotation of the chain belt 3 and the cleaning belt 4, and when the chain belt 3 and the cleaning belt 4 rotate, the chain belt 3 and the cleaning belt 4 are in a differential rotation state. Through the above-mentioned state setting, it is ensured that the cleaning belt 4 is always used for cleaning during the operation of the chain belt 3, to avoid the accumulation of debris on the chain belt 3 and the clogging of the chain belt 3, and to reduce the chain belt 3 malfunction caused by the clogging of debris.

[0028] Two stop wheels 15 are rotatably mounted on the conveying frame 2 and corresponding to the position of each cleaning shaft 14 , and the two stop wheels 15 are both in contact with the chain belt 3 .

[0029] When the chain belt 3 is driven by the sprocket group, the two blocking wheels 15 can limit the chain belt 3 to prevent the chain belt 3 from deviating during operation, and can effectively reduce the probability of external blockages entering the joint between the chain belt 3 and the sprocket, thereby reducing the deformation of the chain belt 3 caused by the entry of foreign objects and the rate of chain belt 3 falling out; At the same time, when the chain belt 3 is impacted by external force or has local deformation, the retaining wheel 15 can provide timely support and restraint to the chain belt 3 to prevent the chain belt 3 from falling off due to displacement or excessive deformation, thereby solving the technical problem that the chain belt 3 is prone to falling off due to deformation or displacement. The outstanding beneficial effect is to improve the stability of the chain belt 3 operation, reduce the occurrence of chain falling failures, and extend the service life of the chain belt 3.

[0030] The sprocket assembly also includes a differential shaft 16 rotatably connected to the conveying frame 2, a first differential bevel tooth is installed on the sprocket shaft 13 on the driving sprocket member and the differential shaft 16, and the two first differential bevel teeth are meshed with each other, and a second differential bevel tooth is installed on the cleaning shaft 14 on the driving sprocket member and the differential shaft 16, and the two second differential bevel teeth are meshed with each other.

[0031] When the sprocket shaft 13 of the driving sprocket rotates, the first differential bevel gear on the sprocket shaft 13 drives the first differential bevel gear on the differential shaft 16 to rotate, thereby causing the differential shaft 16 to rotate, and the second differential bevel gear on the differential shaft 16 drives the second differential bevel gear on the cleaning shaft 14 of the driving sprocket to rotate, thereby realizing the differential transmission of the sprocket shaft 13 and the cleaning shaft 14, ensuring that the rotation speed of the cleaning belt 4 is 1.5 times that of the chain belt 3, solving the problem of the difficulty in accurately controlling the rotation speed difference between the chain belt 3 and the cleaning belt 4 in the prior art, and having a prominent beneficial effect of ensuring that the cleaning belt 4 can more efficiently clean the debris on the chain belt 3, avoiding the debris residue from clogging the chain belt 3, and improving the cleaning effect; When in use, the cleaning shaft 14 on the driving sprocket is connected to a power input device of an external machine, and the other three cleaning shafts 14 are all connected to a power output device.

[0032] The vibration transmission mechanism includes two belt shafts 17 and two first cam shafts 18 rotatably connected to the frame 1. One belt shaft 17 is connected to a transmission shaft 12 through a first belt. A second belt is connected between the two belt shafts 17. First eccentric wheels 19 are installed on the two first cam shafts 18. The two first eccentric wheels 19 are both fitted with the conveying frame 2. The axis of the first cam shaft 18 is perpendicular to the axis of the transmission shaft 12. First bevel gears are installed on the tops of the two first cam shafts 18. Second bevel gears are installed at the tail ends of the two belt shafts 17. The two first bevel gears are respectively connected to the two second bevel gears. A group of elastic reset members 20 are installed between the conveying frame 2 and the frame 1.

[0033] When in use, the transmission shaft 12 rotates to drive a belt shaft 17 to rotate through the first belt, and the belt shaft 17 then drives another belt shaft 17 to rotate through the second belt. At the same time, the second bevel gear on the belt shaft 17 drives the first bevel gear on the first convex shaft 18 to rotate, so that the first convex shaft 18 rotates. The first eccentric wheel 19 on the first convex shaft 18 continuously squeezes the conveying frame 2 as it rotates, so that the conveying frame 2 reciprocates left and right, and the elastic reset member 20 plays a role of buffering and reset. The reciprocating movement of the conveyor frame 2 can cause the chain belt 3 to generate a certain vibration during operation, shaking off the debris attached to the chain belt 3, solving the problem that the chain belt 3 is easily attached with debris and blocked by the debris. The outstanding beneficial effect is to use vibration to assist in cleaning the chain belt 3, thereby enhancing the cleaning effect and reducing the frequency of manual cleaning.

[0034] The elastic reset member 20 comprises a T-shaped guide rod installed on the back of the conveying frame 2 , the T-shaped guide rod is slidably connected to the frame 1 , and a reset spring limited by the frame 1 is sleeved on the T-shaped guide rod.

[0035] When in use, when the first eccentric wheel 19 squeezes the conveyor frame 2 to move the conveyor frame 2 to the left or right, the T-shaped guide rod slides on the frame 1 and the reset spring is compressed. When the first eccentric wheel 19 no longer squeezes the conveyor frame 2, the reset spring releases its elastic force to push the conveyor frame 2 to reset, thereby ensuring that the conveyor frame 2 can stably move back and forth left and right, avoiding the conveyor frame 2 from affecting the vibration cleaning effect of the chain belt 3 due to excessive movement or inability to reset, and solving the problem of unstable movement of the conveyor frame 2 in the vibration transmission mechanism. The outstanding beneficial effect is to ensure that the vibration transmission mechanism continues to work stably, thereby effectively cleaning up debris in the chain belt 3 and maintaining the normal operation of the chain belt 3.

[0036] A tensioning seat 6 and a shaking seat 7 are slidably installed on the conveying frame 2. A group of tensioning springs 8 limited by the conveying frame 2 are installed on the sides of the tensioning seat 6 and the shaking seat 7. A shaking driving mechanism for driving the shaking seat 7 to move up and down is provided on the conveying frame 2. An inner clamping wheel 9 and an outer clamping wheel 10 are rotatably installed on the shaking seat 7 and the tensioning seat 6.

[0037] The shaking drive mechanism includes a square shaft 21 rotatably connected to the frame 1 and a second cam shaft 22 rotatably connected to the conveying shaft. The square shaft 21 is connected to the second belt transmission. The interior of the square shaft 21 is fixedly provided with a square groove with an opening at the tail end and slidably connected to the second cam shaft 22. The cross-sections of the square groove and the second cam shaft 22 are both regular hexagons. A second eccentric wheel 23 is installed on the second cam shaft 22. An I-shaped wheel 24 is rotatably installed on the shaking seat 7. The second eccentric wheel 23 is fitted with the I-shaped wheel 24, and the second cam shaft 22 is arranged parallel to the transmission shaft 12.

[0038] The square shaft 21 rotates driven by the second belt, and the square groove inside the square shaft 21 cooperates with the second cam shaft 22 to rotate the second cam shaft 22. The second eccentric wheel 23 on the second cam shaft 22 continuously squeezes the I-shaped wheel 24 on the shaking seat 7 as it rotates, causing the shaking seat 7 to reciprocate up and down, and the inner clamping wheel 9 and the outer clamping wheel 10 on the shaking seat 7 shake accordingly, further shaking off the debris on the chain belt 3, solving the problem that the debris on the chain belt 3 is difficult to clean thoroughly. The outstanding beneficial effect is that the chain belt 3 is shaken and cleaned from multiple angles, effectively removing stubborn debris on the chain belt 3, and reducing the risk of the chain belt 3 being blocked by debris and falling off.

[0039] The pneumatic cleaning assembly includes a pump barrel 25 installed on the frame 1, and a pump shaft 26 is rotatably installed on the inner wall of the pump barrel 25. The pump shaft 26 is connected to the second belt transmission. A group of pump blades distributed in a circular array are installed on the pump shaft 26 and corresponding to the position on the inner side of the pump barrel 25. A filter element is installed at the air inlet port of the pump shaft 26, and the air outlet port of the pump shaft 26 is connected to a high-pressure nozzle 27. Two symmetrically arranged air distribution pipes 28 are installed on the conveying frame 2, and the air outlet ports of the high-pressure nozzle 27 are connected to the inner cavities of the two air distribution pipes 28 through three-way pipes. Each air distribution pipe 28 is provided with two symmetrically arranged jet surfaces, which are arranged on the inner side of the chain belt 3, and each jet surface is provided with a group of jet holes 29 distributed in a linear array and connected to the inner cavity of the air distribution pipe 28.

[0040] The pump shaft 26 rotates driven by the second belt, and the pump blades on the pump shaft 26 rotate accordingly, sucking air into the pump barrel 25 and compressing it, and ejecting high-pressure gas through the high-pressure nozzle 27. The high-pressure gas enters the gas distribution pipe 28 through the three-way pipe, and then is ejected to the inside of the chain belt 3 from the jet hole 29, thereby pneumatically cleaning the chain belt 3 and removing fine debris in the gaps of the chain belt 3, solving the problem that the debris inside the chain belt 3 is difficult to clean. The outstanding beneficial effect is that it can clean deeply inside the chain belt 3, making up for the shortcomings of mechanical cleaning, effectively preventing debris from clogging the chain belt 3 and causing the chain belt 3 to deform, thereby improving the cleanliness and service life of the chain belt 3.
