Description

Technical Field

[0001] The present invention relates to the technical field of screw conveying, and more specifically, the present invention relates to a biochar-based fertilizer loading conveyor. Background Art

[0002] During the loading process of biochar-based fertilizers, a screw conveyor for loading biochar-based fertilizers can improve the loading efficiency. The screw conveyor transports the biochar-based fertilizers by pushing them with rotating screw blades. This continuous transportation method can significantly improve the loading efficiency and reduce the cumbersome and time-consuming manual loading.

[0003] In the existing publicly available technical literature, the patent with the Chinese patent publication number CN208932330U discloses a screw conveyor assembly for preparing curved blocks. This technology mainly has a discharge port installed at the bottom side of the screw conveyor body, and the discharge port is connected to the inside of the screw conveyor body. A fixed rod is fixedly installed on the top side of the base, a fixed pulley is fixedly installed on one side of the fixed rod, and a wire winding mechanism is installed on the top side of the base. The wire winding mechanism includes an electromagnetic brake motor fixedly installed on the top side of the base, a rotating shaft is fixedly connected to the output shaft of the electromagnetic brake motor, and a wire winding roller is fixedly sleeved on the rotating shaft. This utility model can adjust the height of the discharge port to facilitate adaptation to loading vehicles of different heights, is easy to move, has a simple structure, and is convenient to operate. However, this technology still has the following problems.

[0004] When the loading conveyor transports biochar-based fertilizers, it needs to be transported in a spiral manner, and the spiral transportation area is relatively single. When the feeding volume of the feeding hopper is large, it is difficult to timely disperse and dock the large amount of materials for transportation. This results in a large feeding volume of the feeding hopper and a small discharging volume, less discharging and more feeding. Therefore, it is difficult to automatically and quickly conduct large-area docking transportation according to the large feeding volume of biochar-based fertilizers, and the feeding contact area is smaller, resulting in a significant decrease in transportation efficiency. Therefore, a biochar-based fertilizer loading conveyor is needed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: A biochar-based fertilizer loading conveyor, including a spiral conveying channel, a double-hole hopper, and two docking side frames. The double-hole hopper is fixedly communicated with the upper inclined surface of the spiral conveying channel, and the two docking side frames are respectively fixedly communicated with the two side surfaces of the spiral conveying channel. A synchronous docking and conveying mechanism is provided on the inner wall of the docking side frame; the synchronous docking and conveying mechanism includes a docking groove opened on the inner wall of the docking side frame, a side hopper is provided on one side of the docking side frame, a diversion channel is fixedly communicated with one side of the side hopper, a support ring is fixedly connected to the outer wall of the diversion channel, and a socket slider is fixedly connected to the top end of the support ring.

[0006] One side of the socket slider is fixedly installed with a connecting shaft. The outer wall of the connecting shaft is rotationally connected with a socket rod. The inner wall of the socket rod is rotationally connected with a linkage shaft at a position far from the connecting shaft. One end of the linkage shaft is fixedly connected with a concave block, and a support block is fixedly installed on one side of the concave block. A pressure sensor is fixedly connected to the lower inclined surface of the support block. A push electric cylinder is fixedly connected between the pressure sensor and the spiral conveying channel. The inner wall of the spiral conveying channel is rotationally connected with a main spiral auger. A synchronous opening docking conveying mechanism is installed at the bottom end of the spiral conveying channel. A displacement detection docking conveying assembly is arranged on the upper surface of the double-hole hopper.

[0007] Preferably, the side hopper is movably inserted into the docking groove. The inner wall of the docking groove and the outer wall of the side hopper are both smooth surfaces. The concave block is rotationally connected with the socket rod. The push electric cylinder is used to push the pressure sensor to move. The outer wall of each socket slider is slidably connected with an inclined frame. The bottom end of the inner wall of the inclined frame is fixedly installed with an inclined rod. The inclined rod is slidably connected with the socket slider. A reinforcing frame is fixedly connected between the two inclined frames, and the reinforcing frame is fixedly connected with the spiral conveying channel. The support ring is slidably connected with the inclined frame. The bottom end of the outer wall of the spiral conveying channel is fixedly connected with a mounting frame, and a controller is fixedly installed on one side of the mounting frame.

[0008] The top end of the main spiral auger is fixedly installed with a driving motor, and the driving motor is used to drive the main spiral auger to rotate. The driving motor is fixedly connected with the spiral conveying channel. A lower discharge pipe is fixedly communicated with the outer wall of the spiral conveying channel near the driving motor.

[0009] The inner wall of the diversion channel is rotationally connected with a secondary spiral auger. The top end of the secondary spiral auger is fixedly installed with a transmission motor. The transmission motor is fixedly connected with the diversion channel. The transmission motor is used to drive the secondary spiral auger to rotate. A diversion pipe is fixedly communicated with the bottom end of the outer wall of the diversion channel. An induction block is fixedly connected to the upper surface of the side hopper, and a docking distance sensor is fixedly connected to the upper surface of the docking side frame.

[0010] When the present technology is in use, the push electric cylinder pushes the pressure sensor to move upward. The support block causes the concave block to move upward. The concave block drives the two linkage shafts to move upward synchronously. The socket rod drives the connecting shaft to tilt upward. The socket slider tilts upward along the outer wall of the inclined rod. The socket slider drives the support ring to tilt upward. The support ring drives the diversion channel to tilt upward. At the same time, the diversion channel drives the side hopper to tilt upward. The side hopper is inserted into the inner wall of the docking groove. The docking side frame wraps and positions the outer wall of the side hopper. When the distance value sensed by the docking distance sensor is the same as the distance value set by the controller, and at the same time the pressure value sensed by the pressure sensor is the same as the distance value set by the controller, the push electric cylinder is closed by the controller.

[0011] Preferably, the synchronous opening and docking conveying mechanism includes a support block fixedly installed at the bottom end of the spiral conveying channel; a linkage electric cylinder is fixedly connected to the upper surface of the support block, a moving distance sensor is fixedly installed on one side of the linkage electric cylinder, the output end of the linkage electric cylinder is fixedly connected to a double-groove frame, two sliding shafts are slidably connected to the inner wall of the double-groove frame, and one end of each sliding shaft is fixedly connected to an inclined sliding plate; the outer wall of each inclined sliding plate is slidably connected to a socket support plate, both socket support plates are fixedly connected to the double-hole hopper, an inclined baffle is fixedly installed at the bottom end of each inclined sliding plate, and both inclined baffles are slidably connected to the double-hole hopper; two limiting rings are fixedly connected to the outer wall of the sliding shaft. The two limiting rings are symmetrically arranged with respect to the double-groove frame, and the limiting rings are slidably connected to the double-groove frame.

[0012] When the present technology is in use, the linkage electric cylinder drives the double-groove frame to move upward, and at the same time, the sliding shaft drives the two limiting rings to move rightward. One sliding shaft moves rightward along the inner wall of the double-groove frame, and the other sliding shaft moves leftward along the inner wall of the limiting ring. The inclined sliding plate slides upward obliquely along the inner wall of the socket support plate, and the inclined sliding plate drives the inclined baffle to slide upward obliquely. The two inclined baffles can synchronously slide upward obliquely, so that the biochar-based fertilizer inside the double-hole hopper can be shunted along the two side holes and docked into the two side hoppers, and then poured into the shunt channel through the side hoppers. In this way, the two shunt channels can be quickly docked and connected to the double-hole hopper, and the two-side docking and shunting of a large amount of biochar-based fertilizer can be realized quickly.

[0013] Preferably, the displacement detection and docking conveying assembly includes a support column fixedly arranged on the upper surface of the double-hole hopper; one end of the support column is fixedly installed with a guide frame, and a screw rod is rotatably connected to the inner wall of the guide frame. A displacement motor is fixedly installed at one end of the guide frame, and the displacement motor is used to drive the screw rod to rotate; a socket support block is threadedly connected to the outer wall of the screw rod, a detection distance sensor is fixedly installed at the bottom end of the socket support block, and a displacement support block is fixedly connected to one side of the socket support block; displacement distance sensors are arranged on both sides of the displacement support block, and both displacement distance sensors are fixedly connected to the guide frame. The displacement support block is slidably connected to the guide frame, and the outer wall of the socket support block and the inner wall of the guide frame are both smooth surfaces.

[0014] When this technology is in use, start the indexing motor to drive the screw to rotate forward. The screw drives the socket support block to move leftward under the action of the thread driving force. The socket support block drives the detection distance sensor to move leftward. The detection distance sensor drives the indexing support block to move leftward. In this way, the indexing support block moves away from the indexing distance sensor on the right side. If the distance value sensed by the left indexing distance sensor is the same as the indexing distance set by the controller, then start the indexing motor to drive the screw to rotate backward through the controller. In this way, the socket support block drives the indexing support block to move rightward under the action of the thread driving force. In this way, the detection distance sensor can realize reciprocating indexing movement to the left and right. When the distance value sensed by the detection distance sensor is less than the distance value set by the controller, it is known that the feed rate of the biochar-based fertilizer is relatively large.

[0015] The technical effects and advantages of the present invention are as follows:

[0016] 1. Through the synchronous docking and conveying mechanism of the present invention, the pushing cylinder is pushed to move the pressure sensor upward. The concave block drives the two linkage shafts to move upward synchronously. The connecting shaft drives the socket slider to move obliquely upward. The socket slider drives the support ring to move obliquely upward. The support ring drives the shunt channel to move obliquely upward. The shunt channel drives the side hopper to move obliquely upward. The side hopper drives the induction block to move obliquely upward. The side hopper is inserted into the inner wall of the docking groove. When the distance value sensed by the docking distance sensor is the same as the distance value set by the controller, and at the same time the pressure value sensed by the pressure sensor is the same as the distance value set by the controller, then the pushing cylinder is closed through the controller. The two side hoppers can be synchronously docked to the two side holes of the double-hole hopper according to the specified pressure and the specified distance, and can realize automatic, fast and large-area docking and shunt conveying according to the large feed rate of the biochar-based fertilizer inside the double-hole hopper, greatly improving the conveying efficiency.

[0017] 2. By using the synchronous opening and docking conveying mechanism of the present invention, the linkage cylinder drives the double-slot frame to move upward. The double-slot frame drives the two sliding shafts to move upward. The sliding shafts drive the two limit rings to move rightward. One sliding shaft moves rightward along the inner wall of the double-slot frame, and the other sliding shaft moves leftward along the inner wall of the limit ring. The inclined slide plate moves obliquely upward along the inner wall of the socket support plate. The two inclined baffles can move obliquely upward synchronously. The biochar-based fertilizer inside the double-hole hopper can be shunted and docked into the two side hoppers along the two side holes, and can realize synchronous side-discharge docking operations on both sides of the double-hole hopper, and can realize automatic, fast and large-area docking and shunt conveying according to the large feed rate of the biochar-based fertilizer inside the double-hole hopper, greatly improving the conveying efficiency.

[0018] 3. The present invention adopts a displacement detection and docking conveying assembly. The controller can start the displacement motor to drive the screw to rotate forward. The screw drives the socket support block to move leftward under the action of the thread driving force. The socket support block drives the detection distance sensor to move leftward, and the detection distance sensor drives the displacement support block to move leftward. The distance value sensed by the left displacement distance sensor is the same as the displacement distance set by the controller. By starting the displacement motor to drive the screw to rotate reversely through the controller, the sensed distance value of the detection distance sensor is less than the set distance value by the controller, it can be known that there is a large amount of biochar-based fertilizer inside the screw conveying channel, and it quickly moves towards the top opening position of the double-hole hopper, and it can be known that a large amount of feeding starts around the internal biochar-based fertilizer. Thus, according to the large feeding amount of biochar-based fertilizer inside the double-hole hopper, automatic, rapid, large-area docking and diversion conveying can be realized.

[0019] Due to the mutual influence of the above multiple functions, first, it can be known that there is a large amount of biochar-based fertilizer inside the screw conveying channel, and it quickly moves towards the top opening position of the double-hole hopper. Second, the two side hoppers can be synchronously docked at the two side holes of the double-hole hopper according to the specified pressure and specified distance. Finally, the two inclined baffles can be tilted upward synchronously, and the biochar-based fertilizer inside the double-hole hopper can be diverted and docked into the two side hoppers along the two side holes. In summary, according to the large feeding amount of biochar-based fertilizer inside the double-hole hopper, automatic, rapid, large-area docking and diversion conveying can be realized, the conveying contact area is wider, and the conveying efficiency is greatly improved.

One side of the side hopper 5 is fixedly connected with a diversion channel 6. A support ring 7 is fixedly connected to the outer wall of the diversion channel 6, and a socket slider 8 is fixedly connected to the top end of the support ring 7.

[0034] A connecting shaft 9 is fixedly installed on one side of the socket slider 8. A socket rod 10 is rotatably connected to the outer wall of the connecting shaft 9. A linkage shaft 11 is rotatably connected to the inner wall of the socket rod 10 and far away from the connecting shaft 9. One end of the linkage shaft 11 is fixedly connected with a concave block 12. A support block 13 is fixedly installed on one side of the concave block 12. A pressure sensor 14 is fixedly connected to the lower inclined surface of the support block 13. A push electric cylinder 15 is fixedly connected between the pressure sensor 14 and the spiral conveying channel 1. A main spiral auger 21 is rotatably connected to the inner wall of the spiral conveying channel 1. A synchronous opening docking conveying mechanism is installed at the bottom end of the spiral conveying channel 1. A displacement detection docking conveying component is provided on the upper surface of the double-hole hopper 2.

[0035] In this technical solution, as shown in the attached Figure 1 -attached Figure 4 figure, the concave block 12 is rotatably connected to the socket rod 10. The push electric cylinder 15 is used to push the pressure sensor 14 to move. The outer wall of each socket slider 8 is slidably connected with an inclined frame 16. An inclined rod 17 is fixedly installed at the bottom end of the inner wall of the inclined frame 16. The inclined rod 17 is slidably connected with the socket slider 8. A reinforcing frame 18 is fixedly connected between the two inclined frames 16. The reinforcing frame 18 is fixedly connected with the spiral conveying channel 1. The support ring 7 is slidably connected with the inclined frame 16, so as to facilitate the socket slider 8 to tilt and move upward along the outer wall of the inclined rod 17. At the same time, the socket slider 8 tilts and moves upward along the inner wall of the inclined frame 16, which can realize the inclined guiding operation of the socket slider 8.

[0036] The bottom end of the outer wall of the spiral conveying channel 1 is fixedly connected with a mounting frame 19.

The controller 20 is supported by the mounting frame 19 to increase the stability of the controller 20.

[0037] In this technical solution, as shown in the attached Figure 2 -attached Figure 5As shown in the figure, a driving motor 22 is fixedly installed at the top of the main spiral auger 21, and the driving motor 22 is used to drive the main spiral auger 21 to rotate.

A diversion pipe 26 is fixedly communicated with the bottom end of the outer wall of the diversion channel 6. To facilitate the driving motor 22 to drive the main spiral auger 21 to rotate, the main spiral auger 21 rotates inside the spiral conveying channel 1, so that the biochar-based fertilizer moves along the inside of the spiral conveying channel 1 to the position of the lower discharge pipe 23, realizing the lower discharge of the main channel. When it is detected that the feeding amount in the double-hole hopper 2 is large, the transmission motor 25 is used to drive the secondary spiral auger 24 to rotate. The secondary spiral auger 24 rotates inside the diversion channel 6, and the secondary spiral auger 24 can drive the diverted biochar-based fertilizer into the diversion pipe 26, so that the lower discharge operation is realized through the diversion pipe 26.

[0038] An induction block 27 is fixedly connected to the upper surface of the side hopper 5, and a docking distance sensor 44 is fixedly connected to the upper surface of the docking side frame 3, so as to facilitate the side hopper 5 to drive the induction block 27 to tilt upward, and the docking distance sensor 44 realizes distance sensing of the induction block 27. When the distance value sensed by the docking distance sensor 44 is the same as the distance value set by the controller 20.

[0039] In this technical solution, as shown in the attached Figure 6 -attached Figure 8 figure, the synchronous opening docking conveying mechanism includes a support block 28 fixedly installed at the bottom end of the spiral conveying channel 1. A linkage electric cylinder 29 is fixedly connected to the upper surface of the support block 28. A moving distance sensor 30 is fixedly installed on one side of the linkage electric cylinder 29. The output end of the linkage electric cylinder 29 is fixedly connected to a double-groove frame 45. Two sliding shafts 31 are slidably connected to the inner wall of the double-groove frame 45. One end of each sliding shaft 31 is fixedly connected to an inclined sliding plate 32.

[0040] Each inclined sliding plate 32 is slidably connected to a socket support plate 33. Both socket support plates 33 are fixedly connected to the double-hole hopper 2. An inclined baffle 34 is fixedly installed at the bottom end of each inclined sliding plate 32. Both inclined baffles 34 are slidably connected to the double-hole hopper 2. Two limiting rings 35 are fixedly connected to the outer wall of the sliding shaft 31. The two limiting rings 35 are symmetrically arranged with respect to the double-groove frame 45, and the limiting rings 35 are slidably connected to the double-groove frame 45.

[0041] In this technical solution, as shown in the attached Figure 9 -attached Figure 10As shown in the figure, the displacement detection and docking conveyor assembly includes a support column 36 fixedly arranged on the upper surface of the double-hole hopper 2; one end of the support column 36 is fixedly installed with a guide frame 37, and a screw rod 38 is rotatably connected to the inner wall of the guide frame 37. One end of the guide frame 37 is fixedly installed with a displacement motor 39, and the displacement motor 39 is used to drive the screw rod 38 to rotate; the outer wall of the screw rod 38 is threadedly connected with a socket support block 40, and a detection distance sensor 41 is fixedly installed at the bottom end of the socket support block 40. One side of the socket support block 40 is fixedly connected with a displacement support block 42; displacement distance sensors 43 are arranged on both sides of the displacement support block 42, and both displacement distance sensors 43 are fixedly connected to the guide frame 37. The displacement support block 42 is slidably connected to the guide frame 37, and the outer wall of the socket support block 40 and the inner wall of the guide frame 37 are both smooth surfaces.

[0042] The usage method of the biochar-based fertilizer loading conveyor of the present invention is as follows:

[0043] First, when the present invention performs loading and conveying, expansion bolts are inserted into the holes of the mounting frame 19 to fix the mounting frame 19 on the ground base, so that the mounting frame 19 can provide a stable supporting force. Then, the biochar-based fertilizer is poured into the double-hole hopper 2, enters the spiral conveying channel 1 through the double-hole hopper 2, and the drive motor 22 is started by the controller 20. The drive motor 22 drives the main spiral auger 21 to rotate. The main spiral auger 21 rotates inside the spiral conveying channel 1, so that the biochar-based fertilizer moves along the inside of the spiral conveying channel 1 to the position of the lower discharge pipe 23, and the lower discharge operation is realized by the lower discharge pipe 23, so that the spiral loading and conveying operation of the normal biochar-based fertilizer can be realized.

[0044] Second, when the present invention performs displacement detection and docking conveying, the support column 36 is supported by the double-hole hopper 2, and the support column 36 supports the guide frame 37. The controller 20 can start the displacement motor 39 to drive the screw rod 38 to rotate forward. The screw rod 38 drives the socket support block 40 to move left under the action of the threaded driving force, and the socket support block 40 slides left along the inner wall of the guide frame 37, and the socket support block 40 drives the detection distance sensor 41 to move left.

[0045] The detection distance sensor 41 drives the displacement support block 42 to move leftward, so that the displacement support block 42 moves away from the displacement distance sensor 43 on the right side and approaches the displacement distance sensor 43 on the left side. When the distance value sensed by the left displacement distance sensor 43 is the same as the displacement distance set by the controller 20, the displacement motor 39 is started through the controller 20 to drive the screw 38 to reverse. In this way, the socket support block 40 drives the displacement support block 42 to move rightward under the action of the screw transmission force, so that the detection distance sensor 41 can realize reciprocating displacement movement left and right. At the same time, the detection distance sensor 41 senses the distance of the incoming biochar-based fertilizer inside the double-hole hopper 2. When the distance value sensed by the detection distance sensor 41 is less than the distance value set by the controller 20, it is known that a large amount of biochar-based fertilizer in the spiral conveying channel 1 quickly moves to the top opening position of the double-hole hopper 2. In this way, the incoming amount of biochar-based fertilizer is large and the outgoing amount is small, so it is necessary to quickly carry out large-area docking for discharging.

[0046] Then, when the present invention performs synchronous docking and conveying, the push cylinder 15 is started through the controller 20. The push cylinder 15 pushes the pressure sensor 14 to move upward. The pressure sensor 14 drives the support block 13 to move upward, and the support block 13 causes the concave block 12 to move upward. The concave block 12 drives the two linkage shafts 11 to move upward synchronously. The two linkage shafts 11 respectively drive the tops of the two socket rods 10 to move upward synchronously. The socket rod 10 drives the connecting shaft 9 to move upward obliquely, and the connecting shaft 9 drives the socket slider 8 to move upward obliquely. The socket slider 8 moves upward obliquely along the outer wall of the inclined rod 17, and at the same time, the socket slider 8 moves upward obliquely along the inner wall of the inclined frame 16. At the same time, the spiral conveying channel 1 supports the reinforcing frame 18, and the reinforcing frame 18 provides a stable supporting force for the two inclined frames 16. In this way, the socket slider 8 drives the support ring 7 to move upward obliquely, and the support ring 7 drives the diversion channel 6 to move upward obliquely.

[0047] At the same time, the diversion channel 6 drives the side hopper 5 to move upward obliquely. The side hopper 5 drives the induction block 27 to move upward obliquely, and the side hopper 5 is inserted into the inner wall of the docking groove 4. The docking side frame 3 wraps and positions the outer wall of the side hopper 5, and the docking distance sensor 44 senses the distance of the induction block 27. When the distance value sensed by the docking distance sensor 44 is the same as the distance value set by the controller 20, and at the same time, the pressure value sensed by the pressure sensor 14 is the same as the distance value set by the controller 20, the push cylinder 15 is closed through the controller 20. In this way, the two side hoppers 5 can be docked at the two side holes of the double-hole hopper 2 according to the specified pressure and the specified distance.

[0048] Finally, when the present invention performs synchronous opening and docking conveying, the linkage cylinder 29 is started through the controller 20. And the spiral conveying channel 1 provides a supporting force for the support block 28. The support block 28 stably supports the linkage cylinder 29. The linkage cylinder 29 drives the double-slot frame 45 to move upward, and the double-slot frame 45 drives the two sliding shafts 31 to move upward.

[0049] Meanwhile, the sliding shaft 31 drives the two limiting rings 35 to move rightward. The sliding shaft 31 moves rightward along the inner wall of the double-groove frame 45, and the other sliding shaft 31 moves leftward along the inner wall of the limiting ring 35. The sliding shaft 31 drives the inclined sliding plate 32 to tilt upward. The inclined sliding plate 32 tilts upward along the inner wall of the socket support plate 33, and the double-hole hopper 2 supports the socket support plate 33, increasing the stability between the two socket support plates 33. The inclined sliding plate 32 drives the inclined baffle 34 to tilt upward. The two inclined baffles 34 can tilt upward synchronously. In this way, the biochar-based fertilizer inside the double-hole hopper 2 can be shunted along the two side holes and docked into the two side hoppers 5. It enters the side hopper 5 through the side hopper 5 and is poured into the shunt channel 6 through the side hopper 5. In this way, the two shunt channels 6 can be quickly docked and connected to the double-hole hopper 2, quickly realizing two-side docking and shunting of a large amount of biochar-based fertilizer.

[0050] Meanwhile, the controller 20 starts the two driving motors 25. The driving motor 25 drives the secondary spiral auger 24 to rotate. The secondary spiral auger 24 rotates inside the shunt channel 6, and the secondary spiral auger 24 can drive the shunted biochar-based fertilizer into the diversion pipe 26, realizing the downward discharge operation through the diversion pipe 26. In this way, synchronous docking and shunt transportation of a large amount of biochar-based fertilizer inside the double-hole hopper 2 can be achieved, with a wider transportation contact area and a greatly improved transportation efficiency.
