Detailed Description

The invention is further described below with reference to fig. 1 to 21:

as shown in fig. 1, the remote closed-loop pipeline transportation device of the present invention is not only suitable for long-distance transportation of 1 km or more, but also suitable for short-distance material transportation.

A closed-loop conveying pipeline 2 is arranged between the lower material feeding barrel 3 and the material storage barrel 4, a plurality of driving devices 1 are arranged according to the length and the conveying distance of the conveying pipeline 2, the driving devices 1 drive a closed-loop chain 51 in the conveying pipeline 2 to move, and a material pushing plate disc 52 on the closed-loop chain 51 can drive materials to move along the extending direction of the conveying pipeline 2.

As shown in fig. 2, since the distance of the feeding pipe 2 is too long, a plurality of driving devices 1 are required to simultaneously move the closed-loop chain 51. Each driving device 1 comprises a bracket, a driving disc 11 and a driving motor 12, wherein the driving motor 12 is installed on the bracket, the driving disc 11 is rotated by the driving motor 12 through a transmission structure, and a closed-loop chain 51 provided with a pushing plate disc 52 moves along the extending direction of the conveying pipeline 2 under the action of the driving disc 11.

As shown in fig. 3 and 4, since the material transported by the material transporting pipe 2 is solid particles or a solid-liquid mixture, when the pushing material plate 52 carries the material to move along the extending direction of the material transporting pipe 2, the following problems occur when the driving disk 11 contacts the material on the pushing material plate 52: 1. material particles may get stuck in the driving disc 11, affecting the normal operation of the driving disc 11. 2. Material particles may increase the wear of the drive plate 11 and pusher plate 52. 3. The materials accumulated on the driving plate 11 are easy to decay if the feed is fed for a long time, and the safety of the feed is affected. Therefore, the material needs to be separated from the pushing plate disc 52 before entering the driving disc 11, and the feed is combined with the pushing plate disc 52 after the pushing plate disc 52 leaves the driving disc 11, so that the problem can be effectively solved.

The driving device 1 of the invention adopts an upper layer chain passing structure and a lower layer chain passing structure to well solve the problems. The material pushing plate disc 52 and the closed-loop chain 51 are located on the upper layer before entering the height lowering mechanism, the material pushing plate disc 52 and the closed-loop chain 51 enter the lower layer after leaving the driving disc 11 through the height lowering mechanism, meanwhile, an upper layer blanking port 17 is arranged on the upper layer, a lower layer receiving port 18 is correspondingly arranged on the lower layer, the upper layer blanking port 17 is located above the lower layer receiving port 18, the upper layer blanking port and the lower layer receiving port are communicated through a blanking channel 19, the material pushing plate disc 52 and the closed-loop chain 51 push the material to enter the upper layer blanking port 17, the material falls into the lower layer receiving port 18 downwards under the action of gravity, and the material pushing plate disc 52 and the closed-loop chain 51 in the lower layer receiving port 18 drive the material to move again.

The upper and lower layer chain passing structure can be realized by various ways, wherein the most effective and simple structure can be realized by adding a steering wheel 13 and a steering pipeline 21. The steering wheel 13 is obliquely arranged, the steering wheel 13 is positioned at the lowest end of the steering pipeline 21, and the two parallel pipelines of the steering pipeline 21 are used for the upper-layer chain to pass through and the lower-layer chain to pass through respectively. The closed-loop chain 51 is turned around the edge of the steering wheel 13, the highest end of the steering wheel 13 enables the upper layer chain to enter the driving disc 11 after passing through the upper layer chain, the lowest end of the steering wheel 13 enables the lower layer chain to exit the driving disc 11, and finally the upper layer chain is positioned above the lower layer chain before entering the driving disc 11.

The steering wheel 13 can rotate under the action of the pushing plate disc 52 and the closed-loop chain 51 to reduce abrasion, meanwhile, the steering wheel 13 is acted by the spring 15 to enable the steering wheel 13 to be well matched with the pushing plate disc 52, and when materials are blocked at the position, the spring 15 can be used for realizing recoil to dredge the conveying pipeline 2.

The concrete structure is as follows: a plurality of supporting frames 14 are provided with through holes, one end of the positioning rod is connected with the rotating shaft of the steering wheel 13, the other end of the positioning rod is connected with the through holes passing through the plurality of supporting frames 14, a spring 15 is sleeved at the other end of the positioning rod, one end of the spring 15 is limited on one supporting frame 14, and the other end of the spring 15 is limited on the positioning rod. Therefore, the steering wheel 13 can be brought into abutment with the pusher plate 52 by the action of the spring 15.

As shown in fig. 4, the driving motor 12 drives the primary pulley 121 to rotate, the secondary pulley is connected to the clutch 6, and the primary pulley 121 and the secondary pulley are driven by a belt 122. The transmission between the drive motor 12 and the clutch 6 can be of many types, and this is merely a common transmission.

As shown in fig. 5 and 6, the specific structure of the drive disk 11 is as follows: the chain pushing device comprises an upper driving disk 111 and a lower driving disk 112, wherein the upper driving disk 111 and the lower driving disk 112 are arranged in parallel, a plurality of upper pushing pieces 113 are arranged on the lower bottom surface of the upper driving disk 111 along the circumferential direction, a same number of lower pushing pieces 114 are correspondingly arranged on the upper bottom surface of the lower driving disk 112 along the circumferential direction, a closed-loop chain 51 passes through a space between the upper pushing pieces 113 and the lower pushing pieces 114, and a pushing plate disk 52 is pushed by the upper pushing pieces 113 and the lower pushing pieces 114. To reduce friction, the upper and

lower pushers

113, 114 may rotate.

The upper driving disk 111 and the lower driving disk 112 are connected to the rotating shaft 16 and rotated by the action of the rotating shaft 16. The lower end of the rotating shaft 16 is connected with the driving motor 12 through the clutch 6 and the transmission structure. The rotating shaft 16 is further provided with a material pushing sheet 161, the material pushing sheet 161 can be driven by the rotating shaft 16 to rotate, and the material accumulated below the lower driving disk 112 can be timely guided into a channel between the upper layer blanking port 17 and the lower layer receiving port 18 by the rotating material pushing sheet 161.

As shown in fig. 7 and 8, one of the points of the invention is the clutch 6. The reason why the clutch 6 is used is: when the material conveying pipeline 2 is too long and only one closed-loop chain 51 exists, the closed-loop chain 51 is driven to move by the cooperation of the driving motors 12 of the driving devices 1, but if one or more of the driving motors 12 has a fault or stall, the driving motor 12 can not provide rotating power for the closed-loop chain 51 any more, and can also be an obstacle to the normal operation of the closed-loop chain 51.

The function of the clutch 6 is therefore that if there is a fault or stall in one or more of the drive motors 12 (but at least one drive motor 12 is functioning properly), the clutch 6 will disengage the rotation axis 16 of the corresponding drive disc 11 from the gearing of the corresponding faulty drive motor 12, the drive disc 11 becoming a driven element from the driving element of the chain and no longer being affected by its corresponding drive motor 12.

As shown in fig. 7 and 8, a structure of the clutch 6 of the present invention is as follows: comprises a first transmission piece 61, wherein the first transmission piece 61 is connected with the driving motor 12 through a transmission mechanism, and the driving motor 12 can enable the first transmission piece 61 to rotate. The first transmission member 61 is provided with a second transmission member 62, and the second transmission member 62 is connected to the rotating shaft 16. A movable pressing connecting block 63 is arranged between the first transmission piece 61 and the second transmission piece 62 to realize the separation and the combination of the first transmission piece and the second transmission piece.

The outer wall of the first transmission piece 61 is provided with a key groove 68, and the fixed connection between the driven pulley and the first transmission piece 61 is realized through the matching of a key and the key groove 68. The transmission structure between the driving motor 12 and the driving disk 11 is as follows: the drive motor 12-primary pulley 121-belt 122-secondary pulley-first transmission piece 61 (one of the clutch parts) -movable pressing connection piece 63 (one of the clutch parts) -second transmission piece 62 (one of the clutch parts) -rotating shaft 16-drive plate 11.

The above-described connection structure can be summarized as a connection structure between the drive motor 12 and the drive disk 11 as follows: the driving motor 12, the transmission mechanism 1, the clutch, the transmission mechanism 2 and the driving disc 11. Besides, the connection structure between the driving motor 12 and the driving disk 11 may also be as follows: driving motor 12-transmission mechanism 3-clutch-driving disk 11. Alternatively, the drive motor 12, the reduction mechanism, the clutch, and the drive plate 11.

One end of the movable pressing connecting block 63 is connected with an elastic body 64, a mounting hole part 67 is arranged in the circumferential direction of the second transmission piece 62, the elastic body 64 is positioned in the mounting hole part 67 or a part of the movable pressing connecting block 63 and the whole elastic body 64 are positioned in the mounting hole part 67, and a combining part 65 with a small space and a disengaging part 66 with a large space are arranged between the inner wall of the first transmission piece 61 and the second transmission piece 62.

As shown in fig. 7, when all the driving motors 12 work normally (at the same rotation speed) and the rotation speed meets the design requirement, the work of each driving motor can be transmitted to the closed-loop chain 51, the movable pressing connection block 63 is located at the joint portion 65, the movable pressing connection block 63 is simultaneously pressed by the first transmission piece 61 and the second transmission piece 62, and the driving motors 12 smoothly drive the rotating shaft 16 to rotate.

As shown in fig. 8, when one or more driving motors 12 are not operated normally (including deceleration or stop) and the rotation speed is lower than that of the driving motor which is operated normally, the first transmission member 61 is rotated slowly so that the movable pressing connection block 63 is separated from the inner wall of the first transmission member 61 and moved from the joint portion 65 to the separation portion 66 by the elastic body 64, and the first transmission member 61 rotates idly without affecting the rotation of the second transmission member 62 and the rotating shaft 16.

The abnormal operation of one or more driving motors 12 only causes the driving force of the closed-loop chain 51 to become small and the running speed to become slow, but does not cause the stop of the whole system, when one or more driving motors 12 return to normal operation or the rotating speed is the same as that of other driving motors, the clutch 6 is in the engaged state again, and the driving motor 12 drives the corresponding driving disk 11 to rotate again.

Fig. 8 is a schematic view for easy understanding, and the actual movable pressing connection block 63 may not be visible to the naked eye, so fig. 8 does not represent an actual situation and is only used for reference.

Therefore, the clutch 6 can isolate the driving motor from the whole chain transmission system when the driving motor fails or stalls, so that the failed or stalled driving motor does not influence the normal operation of the whole chain. One of the core points of the present invention is the clutch 6, which can ensure the stability of the operation of the pipeline transportation system because any number of driving motors can be connected on a closed loop chain and the driving motors are not needed to be worried about to influence the movement of the whole chain due to the failure.

Meanwhile, the clutch 6 of the present invention can also automatically move the movable pressing connection block 63 to the joint 65 when the driving motor 12 returns to normal operation, so that the driving motor 12 can effectively output.

The construction of the clutch 6 can be varied and is not limited to the construction of fig. 7 and 8, the clutch of fig. 7-8 being only a preferred embodiment.

As shown in fig. 9, the long-distance pipeline transportation is limited by the influence of terrain and mountain terrain, the material conveying pipeline 2 cannot extend straight, so that the unavoidable existence of the material conveying pipeline 2 requires a direction change design, and in order to ensure the normal operation of the closed-loop chain 51 and the pusher plate disc 52, the directions of the closed-loop chain 51 and the pusher plate disc 52 can be changed by arranging the first direction change wheel 71. The first direction-changing wheel 71 may be a driven wheel or a driving wheel. If one direction-changing wheel cannot achieve the required trend, the second direction-changing wheel 72 can be used for matching, and even more direction-changing wheels can be matched.

As shown in fig. 10, the connection structure of the closed-loop chain 51 and the pushing plate disc 52 is as follows: two connecting parts 521 are respectively arranged on two sides of each pusher plate disc 52, each connecting part 521 comprises a connecting hole 522, and the connection between two adjacent pusher plate discs 52 is realized by the connection between two ends of the closed-loop chain 51 and the connecting hole 522.

As shown in fig. 11, the lower material cylinder 3 can be a conical hopper, the discharge port of the lower material cylinder 3 is located at the lowest end, the discharge port of the lower material cylinder 3 is provided with a feeding motor 31, the feeding motor 31 is connected with a rotary auger 32, the rotary auger 32 feeds the material to a discharge box 33, and the lower end of the discharge box 33 is communicated with the material conveying pipeline 2.

Similarly, the top or upper part of the material storage barrel 4 is communicated with the material conveying pipeline 2, and the material in the material conveying pipeline 2 falls into the material storage barrel 4 through gravity.

The charging hopper 3 and the storage hopper 4 are only one embodiment of the invention, and other types of storage and charging devices are also possible.

The material conveyed by the remote multi-drive closed-loop pipeline conveying system can be solid particles, such as feed or mineral aggregate and the like, or a solid-liquid mixture. The delivery of feed has particular advantages: can prevent people or vehicles from entering the pig farm and prevent the hog cholera virus from entering the pig farm.

In addition, long distance pipeline transportation material is particularly suitable for pig feed transportation mode, and at present, African pigs are heavily abused, and in order to reduce contact between people or vehicles and pig farms, people or vehicles are generally expected to be prevented from entering the pig farms through pipeline transportation of pig feed.

As shown in fig. 12, the drive motor 12 is directly connected to the drive plate 11 via the clutch 6. The driving motor 12 may be a speed-adjustable driving motor, and the motor shaft 123 thereof is directly and fixedly connected with the second transmission member 62 of the clutch 6, and the first transmission member 61 of the clutch is fixedly connected with the driving disc 11.
