Description

Technical Field

[0001] This utility model belongs to the field of seed processing technology, and specifically relates to a variable frequency elevator based on material weight speed regulation. Background Technology

[0002] Seed and kernel processing refers to the process of transforming various plant seeds or kernels from raw materials into finished products that can be eaten, extracted for oil, or used as industrial raw materials. During seed and kernel processing, elevators are used to lift the seed and kernel material from the bottom to the top, achieving vertical transport of the material.

[0003] The existing variable frequency elevator operates as follows: material is fed into the bottom horizontal section inlet, with the conveyor box opening facing upwards, catching the material as it moves horizontally. The conveyor box then enters the vertical lifting section, moving vertically upwards under the traction of the chain. Upon reaching the top horizontal section, the conveyor box opening gradually faces downwards, and the material is ejected under the combined effects of gravity, centrifugal force, and weight, exiting through the top outlet. During the conveying process, the conveying speed of the conveyor box is primarily adjusted by controlling the operating speed of the motor output shaft, which drives the connected rotating shaft to rotate, thereby regulating the rotation speed of the chain between the sprockets.

[0004] However, in actual use, while the appropriate motor output shaft speed can be matched according to the weight of the material, the chain bucket conveyor mechanism has multiple turning points. During speed adjustment, these turning points, due to their different positions, result in inconsistent driven speeds, leading to asynchrony. This can cause the chain and sprocket to jam, causing the material inside the conveyor box to bounce and spill. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the prior art by providing a variable frequency elevator based on material weight speed regulation. Through a speed regulation linkage mechanism, the rotation speed of multiple turning points is controlled according to the weight of the material, ensuring that the sprockets at different positions rotate at the same speed, and ensuring high synchronization between the chain and the sprockets. This avoids the problem of chain and sprocket jamming during the material weight speed regulation process, which would cause the material in the conveyor box to bounce and spill.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a variable frequency elevator based on material weight speed regulation, including a conveyor seat one, an elevator seat fixedly installed on the upper side of the conveyor seat one, and a conveyor seat two fixedly installed on the top of the elevator seat. A chain bucket conveying mechanism is arranged between the interior of the conveyor seat one, the elevator seat, and the conveyor seat two. A speed regulation linkage mechanism is provided on both the conveyor seat one and the conveyor seat two. The chain bucket conveying mechanism includes a driven rotating shaft seat, a drive rotating shaft seat, slide rails, and a tensioning rotating shaft seat. Two slide rails are fixedly installed on both sides of the end of the conveyor seat one away from the elevator seat. A tensioning rotating shaft seat is slidably arranged between two vertically adjacent slide rails. A tensioning rotating shaft is rotatably arranged between the two tensioning rotating shaft seats. The conveyor seat two... Two driven shaft seats are fixedly installed on both sides of the end away from the lifting seat. A driven shaft is rotatably installed between the two driven shaft seats. Two drive shaft seats are fixedly installed on both sides of the end of the conveyor seat one and the conveyor seat two near the lifting seat. A drive shaft is rotatably installed between two horizontally adjacent drive shaft seats. Tension sprockets are fixedly sleeved on both ends of the outer arc surface of the tension shaft. Drive sprockets are fixedly sleeved on both ends of the outer arc surface of the driven shaft. Drive sprockets are fixedly sleeved on both ends of the outer arc surface of the drive shaft. A chain is driven between the tension sprocket, drive sprocket and driven sprocket located in the same vertical plane. Multiple conveyor boxes are rotatably installed between the two chains. A weighing sensor is installed at the lower end of each conveyor box. The speed-regulating linkage mechanism includes a linkage box, linkage shafts, linkage synchronous pulleys, guide rails, tensioning seats, tensioning synchronous pulleys, and steel wire synchronous belts. The linkage box is fixedly installed at one end of conveyor seat one and conveyor seat two near the lifting seat. Two linkage shafts are rotatably installed inside each linkage box. The linkage shafts are connected to the chain bucket conveyor mechanism. Linkage synchronous pulleys are fixedly sleeved on the outer arc surface of each linkage shaft. Guide rails are installed inside each linkage box. Tensioning seats are slidably installed inside each guide rail. Tensioning synchronous pulleys are rotatably installed on each tensioning seat via rotating shafts. Steel wire synchronous belts are used for transmission between the tensioning synchronous pulleys and the two adjacent linkage synchronous pulleys. Conveyor seat one, lifting seat, and conveyor seat two form a Z-shaped structure. The linkage shafts are fixed to the adjacent drive shafts via couplings.

[0007] As a further improvement of this utility model, multiple positioning holes are provided on the guide rails, and multiple positioning bolts are inserted into the tensioning seats. The positioning bolts are threadedly connected to the adjacent positioning holes respectively.

[0008] As a further improvement of this utility model, a drive seat is fixedly installed between the side of the first and second conveyor seats away from the linkage box. A drive shaft is rotatably installed inside the upper and lower sides of the drive seat. A worm wheel is fixedly sleeved on the outer arc surface of the drive shaft. Two bearing seats are fixedly installed inside the upper and lower sides of the drive seat. A worm is rotatably installed between two adjacent bearing seats. The worm is meshed with the adjacent worm wheel. Two drive rods are rotatably installed in the middle of the drive seat. The drive rods are fixed to the adjacent worms by couplings. A dual-axis motor is installed in the middle of the drive seat. The output shafts of the dual-axis motor are fixed to the adjacent drive rods by couplings.

[0009] As a further improvement of this utility model, threaded seats are fixedly provided on both sides of the end of the conveyor seat away from the lifting seat. The threaded seats are threaded with screws inside, and the screws are rotatably connected to the adjacent tensioning shaft seats respectively.

[0010] As a further improvement of this utility model, a feed inlet is provided on the upper surface of the side of the conveyor seat away from the lifting seat, and a sealing plate is slidably provided on the feed inlet. A hopper is provided on the lower surface of the side of the conveyor seat away from the lifting seat, and multiple support legs are provided at the lower end of the conveyor seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the conveying speed of the conveying box is stably controlled according to the weight of the material during the conveying process through a speed-regulating linkage mechanism. Driven by a dual-shaft motor, and through a series of transmission components such as worm gear, worm wheel, drive shaft, and linkage synchronous pulley, it is ultimately ensured that all drive sprockets in the system can rotate quickly, stably, and synchronously in the same direction. This ensures that the movement of the traction chain and the conveying box is highly synchronized, effectively avoiding problems such as chain jamming, accelerated wear, or material spillage in the conveying box that may be caused by asynchronous movement at multiple turning points during the conveying process. Thus, the conveying speed of the conveying box can be stably controlled as needed.

[0012] Secondly, the weighing sensor integrated on the lower side of the conveyor box can monitor the weight of the kernel material inside the box in real time. Based on this weight signal, the control system dynamically adjusts the speed of the dual-axis motor, thereby controlling the running speed of the chain and the conveyor box. Specifically, it appropriately increases the speed under light load to improve efficiency, and actively reduces the speed under heavy load. One of the main purposes of this "slow under heavy load, fast under light load" intelligent strategy is to minimize the spillage and damage of materials during the conveying process. The speed reduction under heavy load prevents materials from shaking out and falling due to inertia, while the speed increase under light load makes the materials more stable inside the box, thus ensuring the integrity and yield of the conveyed materials. This is especially important for kernel materials that are easy to scatter or need to maintain their intact appearance. Attached Figure Description

[0016] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0017] like Figure 2 , 3 As shown, a variable frequency elevator based on material weight speed regulation includes a conveyor seat 101, an elevator seat 102 and a conveyor seat 2 103 connected in sequence, and the three are connected internally by a chain bucket conveying mechanism.

[0018] A lifting seat 102 is fixedly installed on the right side of the first conveyor seat 101, and a second conveyor seat 103 is fixedly installed on the top of the lifting seat 102. A chain bucket conveying mechanism is provided between the interiors of the first conveyor seat 101, the lifting seat 102 and the second conveyor seat 103. A speed regulating linkage mechanism is provided on both the first conveyor seat 101 and the second conveyor seat 103. The first conveyor seat 101, the lifting seat 102 and the second conveyor seat 103 form a Z-shaped structure.

[0019] The speed-regulating linkage mechanism includes a linkage box 301, a linkage shaft 302, a linkage synchronous pulley 303, a guide rail 304, a tensioning seat 305, a tensioning synchronous pulley 307, and a steel wire synchronous belt 308. The linkage box 301 is fixedly installed at one end of the conveyor seat 101 and the conveyor seat 2 103 near the lifting seat 102. Two linkage shafts 302 are rotatably installed inside the linkage box 301. The linkage shafts 302 are connected to the chain bucket conveyor mechanism. The linkage synchronous pulleys 303 are fixedly sleeved on the outer arc surface of the linkage shafts 302. The guide rail 304 is installed inside the linkage box 301.

[0021] like Figure 4As shown, the chain bucket conveyor mechanism includes a driven rotating shaft seat 201, a driving rotating shaft seat 202, slide rails 203, and tensioning rotating shaft seats 204. Two slide rails 203 are fixedly installed on both sides of the end of conveyor seat one 101 away from the lifting seat 102. Tensioning rotating shaft seats 204 are slidably installed between two vertically adjacent slide rails 203, and a tensioning rotating shaft is rotatably installed between the two tensioning rotating shaft seats 204. Two driven rotating shaft seats 201 are fixedly installed on both sides of the end of conveyor seat one 101 and conveyor seat two 103 near the lifting seat 102. A driven rotating shaft is rotatably installed between the two driven rotating shaft seats 201. Two driven rotating shaft seats 201 are fixedly installed on both sides of the end of conveyor seat one 101 and conveyor seat two 103 near the lifting seat 102. The drive shaft seat 202 has a drive shaft rotatably mounted between two horizontally adjacent drive shaft seats 202. Tension sprockets 209 are fixedly mounted on both ends of the outer arc surface of the tension shaft. Driven sprockets 207 are fixedly mounted on both ends of the outer arc surface of the driven shaft. Drive sprockets 208 are fixedly mounted on both ends of the outer arc surface of the drive shaft. A chain 210 is driven between the tension sprockets 209, drive sprockets 208 and driven sprockets 207 located in the same vertical plane. Multiple conveyor boxes 211 are rotatably mounted between two chains 210. A weighing sensor is installed at the lower end of each conveyor box 211. The linkage shaft 302 is fixed to the adjacent drive shafts by couplings.

[0022] like Figure 3 As shown, a drive seat 309 is fixedly installed between the side of conveyor seat 101 and conveyor seat 2 103 away from the linkage box 301. A drive shaft 310 is rotatably installed inside the upper and lower sides of the drive seat 309. A worm gear 311 is fixedly sleeved on the outer arc surface of the drive shaft 310. The drive shaft 310 is fixed to the adjacent drive shaft through a coupling. Two bearing seats 312 are fixedly installed inside the upper and lower sides of the drive seat 309. A worm 313 is rotatably installed between two adjacent bearing seats 312. The worm 313 is meshed with the adjacent worm gear 311. Two drive rods 315 are rotatably installed in the middle of the drive seat 309. The drive rods 315 are fixed to the adjacent worms 313 through a coupling. A dual-axis motor 314 is installed in the middle of the drive seat 309. The output shaft of the dual-axis motor 314 is fixed to the adjacent drive rods 315 through a coupling.

[0023] like Figure 1 , 2 As shown, threaded seats 205 are fixedly installed on both sides of the end of the conveyor seat 101 away from the lifting seat 102. The threaded seats 205 are threadedly connected to screws 206, and the screws 206 are rotatably connected to the adjacent tensioning shaft seats 204 respectively.

[0024] According to another embodiment of the present invention, such as Figure 1 , 4As shown, a feed inlet 104 is provided on the upper surface of the conveyor seat 101 on the side away from the lifting seat 102, and a sealing plate 105 is slidably provided on the feed inlet 104. A hopper 106 is provided on the lower surface of the conveyor seat 103 on the side away from the lifting seat 102, and multiple support legs 107 are provided at the lower end of the conveyor seat 101.

[0025] In operation, the dual-axis motor 314 is controlled to run, causing its output shaft to drive the connected drive rods 315 to rotate. This, in turn, causes the upper and lower drive rods 315 to rotate synchronously. Each drive rod 315 then drives its connected worm gear 313 to rotate. Through the meshing relationship between the worm gear 313 and the worm wheel 311, the drive shaft 310 containing the worm wheel 311 rotates. This causes the upper and lower drive shafts 310 to rotate synchronously in the same direction, thereby driving the connected drive shafts to rotate. The drive shaft drives the linkage shaft 302 connected to it to rotate, which in turn drives the linkage synchronous pulley 303 connected to it to rotate. In turn, through the transmission relationship between the steel wire synchronous belt 308, the tensioning synchronous pulley 307 and the linkage synchronous pulley 303, the linkage synchronous pulleys 303 on the upper and lower sides are driven to rotate synchronously and stably in the same direction. This causes the four linkage synchronous pulleys 303 in the middle to rotate synchronously and stably in the same direction, which in turn drives the four drive shafts in the synchronous direction to rotate synchronously and stably in the same direction. This allows all the drive sprockets 208 to rotate quickly and stably in the same direction. Since the tension sprocket 209, drive sprocket 208, driven sprocket 207, chain 210 and conveyor box 211 form a Z-shaped chain bucket conveyor mechanism, and all the drive sprockets 208 are located at the middle turning point of this Z-shaped chain bucket conveyor mechanism, through the drive of the dual-shaft motor 314 and the cooperation of the synchronous belt linkage mechanism composed of the wire synchronous belt 308, the tension synchronous belt pulley 307 and the linkage synchronous belt pulley 303, all the drive sprockets 208 located at the middle turning point can be driven to rotate quickly and stably in the same direction, thereby driving the chain 210 to rotate quickly and stably, and then driving the conveyor box 211 set between the two chains 210 to move under the rotation of the chain 210, thereby realizing the lifting and conveying of materials in the conveyor box 211; During the conveying process, the weighing sensor on the lower side of the conveying box 211 detects the weight of the kernel material inside the conveying box 211, and then controls the rotation speed of the output shaft of the dual-axis motor 314. This allows for quick and stable control of the rotation speed of the drive sprocket 208 located in the middle, driving the conveying speed of the conveying box 211 suspended between the two chains 210. This increases the conveying speed under light loads, making it less likely for the kernels in the conveying box to shake out. Under heavy loads, the conveying speed is reduced to prevent the kernels from shaking out and falling out of the conveying box due to inertia if the conveying speed is too fast.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
