Description

Technical Field

[0001] This invention relates to the field of grain feeding technology, specifically to an automatic grain feeding and transfer device. Background Technology

[0002] Bucket elevators are continuous conveying machines that use a series of buckets evenly fixed to a ring-shaped traction component to vertically lift materials. They transport bulk materials upwards in a vertical or near-vertical direction using a series of buckets fixed to a traction chain or belt. They are mainly divided into three types: ring chain, plate chain, and belt. Bucket elevators are commonly used for conveying materials during grain drying.

[0003] In traditional elevators, materials are fed into the machine mainly by their own gravity during normal operation. This gravity-feeding method easily leads to a large accumulation of grain material at the bottom of the elevator. When the bucket moves to the bottom material collection area, it needs to overcome the resistance of the accumulated material to complete the scooping action, which significantly increases the operating load, thereby increasing the equipment load and operating energy consumption. Long-term operation can also accelerate component wear, affecting the stability and service life of the equipment.

[0004] Therefore, an automatic grain feeding and transfer device is proposed to solve the problems mentioned above. Summary of the Invention

[0012] Preferably, two synchronous pulleys are rotatably connected to one side of the outer wall of the drive box, and one end of the drive shaft of the two synchronous pulleys is fixedly connected to two lead screws respectively. The two synchronous pulleys are connected by the same synchronous belt.

[0016] Compared with the prior art, the present invention provides an automatic grain feeding and transfer device, which has the following beneficial effects:

[0017] 1. The present invention adds a material guiding mechanism and a material unloading mechanism at the feed inlet of the elevator. By using the two sets of structures working together, the amount of grain entering the elevator can be reasonably controlled, which helps to reduce the concentrated influx of grain and its accumulation at the bottom of the elevator, reduce the running resistance when the bucket is picking up material, reduce the operating load of the equipment, and at the same time slow down the long-term friction wear of the bucket and extend the service life of the parts.

[0018] 2. This invention relies on the linkage between the storage hopper and the feeding box to stably and orderly transport grain into the guide box; the drive shaft inside the feeding box rotates and drives the partition baffle to rotate synchronously, and the grain is quantitatively transported by means of the storage interval formed by the adjacent baffles. By adjusting the rotation speed of the drive shaft, the grain feeding speed can be flexibly controlled, thereby achieving precise control of the feeding amount and ensuring that the elevator feeds smoothly and orderly.

[0019] 3. The present invention equips a stirring rod inside the storage hopper. Relying on the linkage between the pulley and the transmission belt, the stirring rod and the drive shaft of the feeding box can be synchronously linked and operated. While the feeding mechanism feeds the grain in a quantitative manner, the stirring rod continuously stirs and agitates the grain in the storage hopper to prevent the grain from getting damp and clumping, hardening and blocking, avoiding the problem of material caking and jamming, improving the stability of grain feeding, and ensuring continuous operation.

[0020] 4. The present invention has an adjustable guide plate inside the guide box. The guide plate is driven by the adjustment component to complete the angle deflection adjustment. The material flow rate and falling flow rate are changed by the change of the tilt angle of the guide plate. At the same time, it can be coordinated and matched with the speed of the feed box drive shaft for bidirectional cooperation and precise control of the grain feeding rhythm, ensuring that the grain enters the elevator at a uniform speed and evenly, and adapting to the feeding requirements of different working conditions.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example:

[0032] Please see Figure 1 - Figure 8An automatic grain feeding and transfer device in this embodiment includes a bucket elevator housing 1. A feed inlet is provided on one side of the outer wall of the housing 1, and a guiding mechanism 3 is installed on the inner wall of the feed inlet. A discharging mechanism 4 is installed on the top outer wall of the guiding mechanism 3. A discharge outlet is provided on one side of the top outer wall of the housing 1, and a discharging pipe 5 is fixedly connected to the inner wall of the discharge outlet. A lifting motor 6 is fixedly connected to the other side of the top outer wall of the housing 1. The guiding mechanism 3 includes a guiding box 8 fixedly connected to the inner wall of the feed inlet, and a support frame 9 is fixedly connected to the bottom outer wall of the guiding box 8. The discharging mechanism 4 includes an auxiliary frame 11 fixedly connected to the guiding box 8, and a storage hopper 15 is fixedly connected to the outer wall of the auxiliary frame 11. A discharging box 12 connected to the storage hopper 15 is fixedly connected to the bottom outer wall of the storage hopper 15. The discharging box 12 is connected to the guiding box 8 through a pipe. A protective cover 14 is fixedly connected to the top outer wall of the storage hopper 15, and a rectangular opening is provided on the bottom outer wall of the protective cover 14.

[0033] In this embodiment, when continuous feeding and transfer of grain materials is required, the operator can first put the grain materials into the top of the protective cover 14. The grain falls steadily into the storage hopper 15 through the rectangular opening at the bottom of the protective cover 14. The material is then sequentially guided and transported to the outer shell 1 of the bucket elevator through the feeding box 12 and the guide box 8. After the lifting motor 6 starts, it drives the lifting and conveying structure to operate, continuously conveying the grain entering the outer shell 1 upwards, and completing the discharge and transfer through the feeding pipe 5 connected to the top discharge port. This device, through the linkage between the feeding mechanism 4 and the guide mechanism 3, can reasonably control the feed flow of grain into the outer shell 1, avoid material accumulation, and improve the operational stability of the elevator.

[0034] Please see Figure 3 - Figure 5 The inner walls of both sides of the feeding box 12 are rotatably connected to the same drive shaft 20, and the outer wall of the drive shaft 20 is fixedly connected to multiple baffles 21 distributed at equal intervals. One end of the drive shaft 20 is fixedly connected to a second pulley 19. The inner walls of both sides of the storage hopper 15 are rotatably connected to the same stirring rod 16, and one side of the outer wall of the storage hopper 15 is rotatably connected to a first pulley 17. One end of the drive shaft of the first pulley 17 is fixedly connected to the stirring rod 16. The first pulley 17 and the second pulley 19 are connected to the same belt 18. One side of the outer wall of the auxiliary frame 11 is fixedly connected to a feeding motor 13, and the output shaft of the feeding motor 13 is fixedly connected to the drive shaft 20.

[0035] In this embodiment, during the material feeding operation, the feeding motor 13 starts and acts as a power source, directly driving the drive shaft 20 to rotate, which in turn drives the baffles 21, which are equidistantly arranged outside the shaft, to rotate synchronously. The independent material storage space formed between two adjacent sets of baffles 21 enables the separated and quantitative conveying of grain, thereby reducing the large-scale influx of material at once. Operators can adjust the rotational speed of the feeding motor 13 to flexibly change the rotational frequency of the baffles 21, thus reasonably adjusting the overall feeding rate and feed volume. During the operation of the drive shaft 20, the linkage transmission structure of pulley 17, pulley 19, and transmission belt 18 synchronously drives the stirring rod 16 inside the storage hopper 15 to rotate continuously. The stirring rod 16 can continuously stir and loosen the grain accumulated in the storage hopper 15, helping to reduce grain dampness, clumping, and agglomeration, alleviating material blockage and feeding delays, continuously ensuring smooth grain feeding, and stabilizing the overall feeding operation efficiency.

[0036] Please see Figure 6 - Figure 8 The inner walls of both sides of the guide box 8 are rotatably connected to guide plates 10, and the top outer wall of the guide plates 10 is provided with a guide groove. An opening 1 is provided at the end of the guide box 8 near the outer shell 1. A cleaning port is provided on one side of the outer wall of the guide box 8, and a cover plate 22 is fixedly connected to the inner wall of the cleaning port. An opening 2 is provided at the end of the guide box 8 away from the outer shell 1, and an adjustment assembly is installed on the inner wall of the opening 2. The adjustment assembly includes a drive box 23 fixedly connected to the inner wall of the opening 2, and a strip-shaped opening is provided on one outer wall of the drive box 23. A drive seat 26 is slidably connected to the inner wall of the strip-shaped opening. Two lead screws 33 are rotatably connected to the inner walls of both sides of the drive box 23, and the drive seat 26 is screwed onto the outer wall of the two lead screws 33. Two synchronous pulleys 34 are rotatably connected to one outer wall of the drive box 23, and one end of the drive shaft of each of the two synchronous pulleys 34 is fixedly connected to... Two lead screws 33 are connected to two synchronous pulleys 34 by the same synchronous belt 25. A servo motor 24 is fixedly connected to the outer wall of the drive box 23, and the output shaft of the servo motor 24 is fixedly connected to one of the synchronous pulleys 34. The adjustment assembly also includes a support base 29 and two slide rods 28. The two ends of the two slide rods 28 are fixedly connected to the support base 29 and the drive box 23 respectively. The outer walls of the two slide rods 28 are slidably connected to the same sliding seat 27, and the top outer wall of the sliding seat 27 is fixedly connected to a mounting bracket 31. The two mounting brackets 31 are rotatably connected to the same roller 32. One end of the drive base 26 is fixedly connected to the sliding seat 27. A distance sensor 30 is fixedly connected to one side outer wall of the support base 29, and the distance sensor 30 is located at the center line of the support base 29. The roller 32 is in contact with the guide plate 10.

[0037] In this embodiment, after the grain falls from the feeding box 12 into the guide box 8, it is smoothly guided along the guide plate 10 with the guide groove and directionally conveyed to the feeding end of the elevator shell 1. When the speed of the feeding motor 13 changes or the material feeding flow fluctuates, the tilt angle of the guide plate 10 can be adjusted in real time by the adjustment component to achieve matching adjustment of the feeding flow rate. During the angle adjustment operation, the servo motor 24 is started, driving the single-sided synchronous wheel 34 to rotate, which, together with the synchronous belt 25, drives the two sets of lead screws 33 to rotate synchronously in the same direction. The rotation of the lead screw 33 drives the externally screwed drive seat 26 to slide smoothly laterally along the strip opening of the drive box 23. The drive seat 26 synchronously drives the sliding seat 27 to move linearly along the slide bar 28, thereby driving the roller shaft 32 to move synchronously. The roller shaft 32 is always in contact with the bottom surface of the guide plate 10, and changes the flip angle of the guide plate 10 by pushing.

[0038] When the sliding seat 27 moves towards the elevator housing 1, the roller 32 lifts the guide plate 10 to the end near the storage hopper 15, reducing the inclination slope of the guide plate 10 and slowing down the grain flow rate. When the sliding seat 27 moves in the opposite direction, the inclination slope of the guide plate 10 increases, and the material accelerates down the slope by its own weight, effectively increasing the feeding rate. The distance sensor 30 installed on the support seat 29 can collect the displacement data of the sliding seat 27 in real time, effectively feeding back the angle parameters of the guide plate 10. Combined with the speed signal of the feeding motor 13, a linkage control logic is formed. When the speed of the feeding motor 13 increases, the inclination angle of the guide plate 10 is correspondingly reduced to buffer the feeding. When the speed of the feeding motor 13 decreases, the inclination angle of the guide plate 10 is correspondingly increased to accelerate the feeding, realizing the dynamic matching of the feeding speed and the guiding angle, ensuring that the grain enters the elevator at a uniform speed and evenly.

[0039] Meanwhile, the side wall of the feed box 8 is equipped with a cleaning port with a removable cover plate 22, which facilitates the cleaning and maintenance of residual materials and impurities inside the box in the later stage, thereby improving the practicality and ease of maintenance of the equipment.

[0040] Please see Figure 1 An inspection port is provided on one side of the outer wall of the outer casing 1, and an inspection plate 2 is fixedly connected to the inner wall of the inspection port. Two conveyor rollers are rotatably connected to the inner walls of both sides of the outer casing 1, and the two conveyor rollers are connected to the same conveyor belt. A protective casing 7 is fixedly connected to the outer wall of the outer casing 1, and two sprockets are rotatably connected to the inner wall of the protective casing 7. One end of the drive shaft of one sprocket is fixedly connected to the conveyor roller. A gearbox is fixedly connected to the top outer wall of the outer casing 1, and one end of the drive shaft of the other sprocket is fixedly connected to the output shaft of the gearbox. The output shaft of the lifting motor 6 is fixedly connected to the input shaft of the gearbox. The two sprockets are connected to the same chain.

[0041] In this embodiment, an inspection port is provided on the side wall of the hoist housing 1 and a detachable inspection plate 2 is provided. The disassembly is convenient and the sealing is good, which makes it easy for operators to regularly inspect, maintain and troubleshoot the conveying components, hoppers and transmission components inside the housing 1, reducing the difficulty of equipment maintenance.

[0042] During the grain lifting and transfer process, the lifting motor 6 outputs power and transmits it to the reduction gearbox. After the reduction gearbox adjusts the torque and speed, it drives the sprocket assembly to rotate. The two sets of sprockets achieve synchronous transmission through chains, which in turn drives the conveyor rollers inside the outer casing 1 to rotate. The conveyor rollers drive the conveyor belt to operate in a closed loop, which, together with the evenly distributed hoppers, completes the continuous scooping, lifting, and conveying of grain. The protective outer casing 7 can isolate and protect the external sprockets, chains, and other transmission structures, preventing dust and debris from getting entangled and interfering with the transmission, while also preventing accidental contact by personnel that could cause safety hazards, effectively improving the operational safety of the equipment and the service life of the transmission structure.

[0043] The working principle of the above embodiments is as follows:

[0044] Grain material is fed into the protective cover 14 and falls into the storage hopper 15 through the rectangular opening at the bottom of the protective cover 14. The bottom of the storage hopper 15 is connected to the feeding box 12. The grain is transported to the guide box 8 through the feeding box 12, and then smoothly enters the outer shell 1 after being guided by the guide plate 10 inside the guide box 8. The lifting motor 6 drives the conveying roller and the hopper inside the outer shell 1 to circulate through the gearbox, sprocket and chain drive, lifting the grain at the bottom upwards, and finally unloading and transferring it from the top outlet through the feeding pipe 5.

[0045] The feeding mechanism 4 is fixed above the guide box 8 by the auxiliary frame 11. The feeding motor 13 drives the drive shaft 20 inside the feeding box 12 to rotate synchronously with the circumferentially distributed baffles 21. The grain is quantitatively separated and conveyed by the space between the adjacent baffles 21. The feeding flow rate and feeding speed can be adjusted by changing the speed of the feeding motor 13. The pulley 19 fixed at one end of the drive shaft 20 forms a linkage transmission with the pulley 17 through the belt 18, which in turn drives the stirring rod 16 inside the storage hopper 15 to rotate synchronously. The stirring rod 16 continuously stirs and loosens the grain in the storage hopper 15 to prevent the material from caking and blocking the feeding channel, and ensures continuous and smooth feeding.

[0046] The feed box 8 has two adjustment components at one end of its opening. A servo motor 24 drives a synchronous pulley 34 and a synchronous belt 25, which in turn drives two lead screws 33 to rotate synchronously. This causes the drive seat 26, screwed onto the lead screws 33, to slide along the strip-shaped opening of the drive box 23. The drive seat 26, in conjunction with the sliding seat 27, causes the sliding seat 27 to move laterally along the slide rod 28. The sliding seat 27, via a roller 32 mounted on the mounting bracket 31, abuts against the bottom of the support guide plate 10. The positional movement of the roller 32 changes the tilt angle of the guide plate 10. Combined with the real-time detection of the sliding seat 27's displacement stroke by the distance sensor 30, the guide plate 10's flow slope is dynamically adjusted to match the speed of the feeding motor 13, thereby controlling the grain's falling flow rate and ensuring that the feed rate and lifting speed are matched, preventing material accumulation at the bottom of the outer shell 1. The feed box 8 has a cleaning port with a cover plate 22 on its side for easy cleaning and maintenance of internal debris and residue.

[0047] The outer shell 1 is equipped with a sprocket and chain drive structure with a protective shell 7 to isolate and protect the transmission components; the inspection port on the side wall of the outer shell 1, together with the inspection plate 2, facilitates regular inspection, maintenance and troubleshooting of the internal parts of the equipment. The overall structure has stronger protection and maintainability, and the equipment operates more stably.

[0048] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
