Description

Technical Field

[0001] The invention belongs to the technical field of blended fertilizers, and in particular relates to a blending material dispensing device and a dispensing method for blended fertilizers. Background Art

[0002] Blended fertilizer, also commonly known as formula fertilizer or BB fertilizer (Bulk Blending Fertilizer), is a special type of compound fertilizer. Its core feature is to fully mix two or more single fertilizers, compound fertilizers or mixed fertilizers with different nutrient contents, different particle forms and different chemical properties according to a predetermined scientific ratio with the help of special mechanical mixing equipment, and finally obtain a finished fertilizer that meets specific needs.

[0003] In order to facilitate the distribution of different fertilizers, a certain amount of fertilizers will be stored in the batching bin, and then the fertilizers will be mixed by feeding different ingredients. During the storage of fertilizers in the batching bin, the inventor found that if the selected raw materials themselves have strong hygroscopicity, such as ammonium nitrate, it is easy to absorb moisture from the air. During the feeding process, with the change of environmental humidity and the accumulation of materials, the increase of absorbed moisture may cause local materials to stick together, and then the phenomenon of hardening occurs; at the same time, if the particles of the raw materials are too fine, their specific surface area is relatively large, and the contact between the particles is closer, the possibility of mutual adsorption and agglomeration during feeding increases, and it is easy to form hardening; and when the air humidity of the feeding environment is high, the fertilizer raw materials are easy to absorb water vapor in the air, especially some hydrophilic fertilizer components. The adsorption of water vapor will make the surface of the particles moist, and in the subsequent extrusion and accumulation of the feeding, it is easy to make the particles stick together and harden. For example, in the rainy season in the south, if the humidity of the feeding place such as the warehouse is not well controlled, this situation is more likely to occur.

[0004] When the fertilizer in the batching bin becomes compacted, it will cause the feed hopper to be blocked, and the feed may be slow or impossible to feed, especially in the feed hopper. The existing solution is to weld and fix a vibration motor at the center of the side of the feed hopper, and use the vibration of the vibration motor to solve the problem of slow or impossible feed. However, the inventor found that although this method of directly welding the vibration motor is simple, the vibration motor cannot move after welding, resulting in the vibration motor being unable to fully vibrate and knock on the entire side of the feed hopper. As a result, sometimes the welded vibration motor still cannot solve the problem of slow or impossible feed.

[0005] Therefore, the existing structure and defects are studied and improved, and a mixing and dispensing device and a dispensing method for mixing fertilizers are provided, in order to achieve a more practical purpose. Summary of the invention

[0036] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be another element centered thereon. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be another element centered thereon at the same time.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A mixing and dispensing device for mixing fertilizers comprises a mixing bin 1, a lower hopper 11 is arranged at the bottom of the mixing bin 1, a conveying pipe 12 is arranged below the lower hopper 11, a vibrating feeder is arranged on the lower hopper 11, and the vibrating feeder comprises a vibrating motor 2, a vibrating slide 21 and a vibrating cam 251, one end of the vibrating slide 21 is provided with a rotatably connected limit shaft 214, the limit shaft 214 is rotatably connected to the side wall of the lower hopper, the vibrating motor 2 is arranged on the vibrating slide 21 so as to be movable back and forth, a vibrating cam 251 for knocking the side wall of the lower hopper is arranged at the output end of the vibrating motor 2, and an adjusting device for driving the other end of the vibrating slide 21 to rotate back and forth is also arranged on the lower hopper.

[0039] The combination of the reciprocating movement of the vibration motor 2 on the vibration slide 21 and the reciprocating rotational movement of the vibration slide 21 enables the vibration cam 251 to perform all-round vibration and knocking on the surface of the conical lower hopper 11, changing the original fixed vibration mode. The all-round vibration and knocking can better enable the fertilizer to be discharged and prevent the fertilizer from being compacted. The all-round vibration mode, especially when knocking on the edge, the vibration will be transmitted to another adjacent surface, thereby better realizing the fertilizer discharge.

[0040] In this embodiment, a through-type slide groove 211 is provided on the vibration slide plate 21, and symmetrically distributed limit grooves 216 are provided on the two side walls of the slide groove 211. A slidably connected limit block 27 is provided in the limit groove 216, and the limit block 27 is fixedly connected to the two ends of the vibration motor 2.

[0041] In this embodiment, the driving mechanism includes a telescopic rod 271 . The limiting groove 216 is provided with a fixedly connected telescopic rod 271 . The extending end of the telescopic rod 271 is fixedly connected to the limiting block 27 .

[0042] In this embodiment, the telescopic rod 271 is an electric hydraulic rod. The addition of the electric hydraulic rod can realize the reciprocating motion of the vibration motor 2 on the vibration slide plate 21 by directly adding an additional power source, which is simple to implement but has a high cost.

[0043] See also Figure 3 In this embodiment, the adjustment device includes a fixed block 23 and an electric hydraulic push rod 232. The side wall of the lower hopper 11 is provided with a fixedly connected fixed block 23, and the fixed block 23 is provided with a rotatably connected electric hydraulic push rod 232. The end of the slide plate is provided with an extension groove, and a slidingly connected extension plate 212 is provided in the extension groove. The extension end of the electric hydraulic push rod 232 is connected to one end of the extension plate 212. The combination of the fixed block 23, the electric hydraulic push rod 232 and the extension plate 212 enables the vibration slide plate 21 to rotate back and forth around the limit axis 214 at a set angle.

[0044] Embodiment 2 is similar to Embodiment 1 and is not described here. The difference from Embodiment 1 is as follows:

[0045] See also Figure 4 , Figure 5 , Figure 6In the present embodiment, the telescopic rod 271 is in the shape of a telescopic tube, the vibration motor 2 is provided with a driving box 24, the driving box 24 is provided with a driving slot 244, the driving slot 244 is provided with a reciprocating driving plate 245, one end of the driving slot 244 is provided with a first hole 2431 and a second hole 2432, a connecting adapter slot is provided between the first hole 2431 and the second hole 2432, a rotatable and sealed connecting adapter plate 243 is provided in the connecting slot, the connecting plate 243 is provided with connecting holes corresponding to the first hole 2431 and the second hole 2432 respectively, a one-way air intake valve 2433 and a one-way air exhaust valve 2434 are respectively provided in the connecting holes, a connecting transfer tube 2411 is provided on the outer side of the first hole 2431, and connecting shunt tubes 241 are provided at both ends of the connecting tube 241, and the extending ends of the shunt tube 241 are respectively connected to the corresponding telescopic rod 271.

[0046] By the reciprocating motion of the driving plate 245 , in coordination with the rotational switching of the one-way air inlet valve 2433 and the one-way air exhaust valve 2434 , the inflation and suction of the interior of the telescopic rod 271 can be realized, thereby realizing the telescopic control of the telescopic rod 271 .

[0047] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, an output shaft is provided at the output end of the vibration motor 2, the vibration cam 251 is fixedly connected to the output shaft, a first gear 254 is fixedly connected to the output shaft, a second gear 253 is rotatably connected and meshed with the first gear 254 is provided on the vibration motor 2, a first connecting member 252 is fixedly connected and bendable at one end of the second gear 253, an extended end of the first connecting member 252 passes through a driving groove 244 and is fixedly connected to a driving plate 245, a first spring 247 is provided in the driving groove 244 for driving the driving plate 245 to automatically restore an initial position, a symmetrically distributed positioning groove 2465 is provided on the inner wall of the driving groove 244, and a positioning groove 2465 is provided in the positioning groove 2465 There is a slidably connected positioning lock tongue 246, and a second spring 2464 is provided in the positioning groove 2465 for driving the positioning lock tongue 246 to automatically pop out, and an adjustment groove 2463 is provided on the driving box 24 at one end of the second gear 253, and a bendable second connecting member 2461 is provided in the adjustment groove 2463, and the two extending ends of the second connecting member 2461 pass through the side wall of the positioning groove 2465 and are connected and fixed with the corresponding positioning lock tongue 246, and a slidably connected adjustment block 2462 is provided in the adjustment groove 2463, and the adjustment block 2462 is fixedly connected to the middle part of the second connecting member 2461, and a pressing plate 255 is fixedly connected and used to press the adjustment block 2462 on the second gear 253. The second gear 253 is installed on the vibration motor 2 through a fixed shaft 256.

[0048] The design of the first connecting member 252, the first spring 247, the first gear 254 and the second gear 253 enables the second gear 253 to pull the driving plate 245 to move through the first connecting member 252 when rotating, and the first spring 247 enables the driving plate 245 to automatically return to the initial position when not pulled by the first connecting member 252, thereby realizing the reciprocating motion of the driving plate 245 while driving the vibration cam 251 to rotate by the conveying shaft 25 without adding an additional power source;

[0049] The design of the positioning lock tongue 246 can pull the driving plate 245 to move to one side through the first connecting member 252 after the second gear 253 rotates half a circle. At this time, the positioning lock tongue 246 can automatically pop out under the action of the second spring 2464 to limit the driving plate 245. As the second gear 253 continues to rotate the remaining half circle, the driving plate 245 cannot move due to the positioning lock tongue 246. When the second gear 253 rotates one circle, the extrusion plate 255 on the second gear 253 squeezes the second connecting member 2461, driving the positioning lock tongue 246 to automatically shrink. At this time, the driving plate 245 can automatically restore the initial position. Such a design can control the gear ratio so that the second gear 253 rotates one circle after the vibration cam 251 rotates a set number of circles. In this way, the vibration cam 251 can vibrate multiple times at one location and then automatically switch to the next location; such a design can enable each point on the side wall of the lower hopper 11 to be fully vibrated and knocked.

[0050] See also Figure 4 and Figure 6 In this embodiment, a transfer hole is provided in the middle of the transfer plate 243, and a matching transfer rod 2421 is provided in the transfer hole. The transfer rod 2421 is spiral, and fixedly connected driving rods 242 are provided at both ends of the transfer rod 2421. The driving rods 242 are movable and sealed to pass through the corresponding driving plate 245 and the driving box 24, and top plates 217 are fixedly connected and used for extruding the driving rod 242 at both ends of the slide groove 211.

[0051] The transfer rod 2421 is designed in a spiral shape, adopting the principle of a hand-pushed bamboo dragonfly in the prior art, and utilizing the spiral characteristics in conjunction with the top plate 217, so that the transfer rod 2421 will automatically move toward the other end after being squeezed by the top plate 217. Due to the spiral characteristics, the transfer plate 243 will be automatically driven to rotate, and the rotation angle can be controlled by the squeezing distance, thereby realizing the automatic switching of the one-way air intake valve 2433 and the one-way exhaust valve 2434 in the first hole 2431 and the second hole 2432. Such a design enables the vibration motor 2 to move to the top plate 217 at one end of the slide groove 211, and the top plate 217 squeezes the transfer rod 2421, so that the one-way air intake valve 2433 in the first hole 2431 is automatically switched to the one-way exhaust valve 2434, so that the inflation of the telescopic rod 271 can be automatically switched to deflation, thereby realizing that the telescopic rod 271 can be automatically recovered after moving to a set distance, and can be automatically switched to extension after being recovered to a set length. Such a design is achieved without adding any additional power equipment, thereby realizing the telescopic control of the telescopic rod 271 and reducing the cost.

[0052] When this embodiment is used:

[0053] When the vibration motor 2 drives the vibration cam 251 to rotate, the first gear 254 rotates synchronously, thereby driving the second gear 253 to move, and the gear ratio of the two is controlled so that after the first gear 254 rotates a set number of times, the second gear 253 rotates one circle. When the extrusion plate 255 on the second gear 253 moves from the drive box 24 to the first gear 254, the first connecting member 252 can pull the drive plate 245 to move and squeeze the first spring 247. At this time, the drive groove 244 is in an air-intake state, and the gas can be sucked into the drive groove 244 through the one-way air intake valve 2433. At this time, the positioning lock tongue 246 automatically pops out under the action of the second spring 2464, limiting the drive plate 245, so that the second During the process of the gear 253 rotating from the first gear 254 to the driving box 24, the driving plate 245 will not move. When the squeezing plate 255 completely moves to the adjusting block 2462 on the driving box 24, the second gear 253 rotates one circle at this time, and the squeezing plate 255 can squeeze the adjusting block 2462, and the positioning lock tongue 246 is automatically retracted through the second connecting member 2461. Under the action of the first spring 247, the driving plate 245 automatically restores the initial position, so that the gas in the driving groove 244 is discharged through the one-way exhaust valve 2434, and then enters the corresponding telescopic tube through the shunt pipe 241, so that the telescopic tube is automatically extended to the set distance. In this way, the telescopic tube is extended sequentially.

[0054] When the vibration motor 2 moves to the end of the slide groove 211, the top plate 217 can squeeze the driving rod 242 to move, and at the same time drive the adapter rod 2421 to move. Since the adapter rod 2421 is spiral, combined with its spiral characteristics, the adapter plate 243 can rotate to a set angle. At this time, the one-way air inlet is transformed into a one-way exhaust port, and the one-way exhaust port is automatically transformed into a one-way air inlet. Therefore, with the reciprocating motion of the driving plate 245, the gas in the telescopic tube can be automatically extracted and discharged outward in turn, realizing the automatic contraction of the telescopic tube, thereby realizing the reciprocating motion of the vibration motor 2 on the vibration slide plate 21.

[0055] Embodiment 3 is the same as Embodiment 1 and is not described here. The difference from Embodiment 1 is as follows:

[0056] See also Figure 8 In this embodiment, the driving mechanism includes a reciprocating screw 263, and a fixedly connected reciprocating screw 263 is provided in the limit groove 216. A connected reciprocating slide tube 262 is provided on the reciprocating screw 263. The reciprocating screw 263 movably passes through the limit block 27, and the limit block 27 is rotatably connected to the reciprocating slide tube 262. An output shaft is provided at the output end of the vibration motor 2, and the vibration cam 251 is fixedly connected to the output shaft. A fixedly connected third gear 26 is also provided on the output shaft, and a synchronous chain 261 is connected between the third gear 26 and the corresponding reciprocating slide tube 262.

[0057] The design of the reciprocating screw 263, the reciprocating slide 262, the third gear 26 and the synchronous chain 261 can enable the vibration motor 2 to drive the vibration cam 251 to rotate, and at the same time, can utilize the characteristics of the reciprocating screw 263 to achieve reciprocating motion of the reciprocating slide 262 along the reciprocating screw 263, thereby achieving the back and forth motion of the vibration motor 2. Such a design has a simple structure and can achieve the back and forth motion of the vibration cam 251 on the lower hopper 11. However, such a design results in a limited number of times the vibration cam 251 knocks at one location, making it impossible for the vibration cam 251 to fully knock at one location and then switch to the next location, which can easily lead to uneven knocking.

[0058] When this embodiment is used:

[0059] Start the vibration motor 2, which drives the vibration cam 251 to rotate. When the conveying shaft 25 rotates, the third gear 26 is driven to rotate. The third gear 26 drives the two reciprocating slides 262 to rotate synchronously through the synchronous chain 261, so that the reciprocating slide 262 moves back and forth along the reciprocating screw rod 263. Since the reciprocating slide 262 is rotationally connected to the limit block 27, the reciprocating slide 262 can drive the limit block 27 to move back and forth synchronously, thereby realizing the reciprocating motion of the vibration motor 2.

[0060] Embodiment 4 is similar to Embodiment 1 and is not described here. The difference from Embodiment 1 is as follows:

[0061] See also Figure 1 , Figure 2 In this embodiment, the batching bin 1 is provided with a plurality of lower hoppers, and both sides of the bottom of the batching bin 1 are provided with symmetrically distributed guide rails 22, and the guide rails 22 include a first guide rail 221 and a second guide rail 222, and the first guide rail 221 and the second guide rail 222 are respectively fixedly connected to the side walls of the lower hopper, and the first guide rail 221 is provided with a first guide groove slidably connected to the limiting shaft 214, and the first guide rail 221 is provided with a number of first fixing holes 223 corresponding to the number of the lower hoppers, and the limiting shaft 214 is provided with a first threaded hole 215, and the first fixing hole 223 is provided with a first threaded hole 216 corresponding to the number of the ... A threaded hole 215 is threadedly connected and used for fixing a first bolt 225 of the limiting shaft 214. The second guide rail 222 is provided with a plurality of second fixing holes 224 corresponding to the number of the lower hopper. The end of the extension plate 212 is provided with an extension shaft 213 that is rotatably connected. The second guide rail 222 is provided with a second guide groove that is slidably connected to the extension shaft 213.

The second fixing hole 224 is provided with a second bolt 226 that is threadedly connected to the second threaded hole 231 and used to fix the fixing block 23.

[0062] The design of the first guide rail 221 and the second guide rail 222 can enable the vibration motor 2 and the vibration slide plate 21 to switch positions according to different needs when there are multiple lower hoppers 11 in some batching bins 1, through the first guide rail 221 and the second guide rail 222, so that one vibration motor 2 can knock and vibrate multiple lower hoppers 11, thereby saving costs;

[0063] When this embodiment is used:

[0064] When one of the lower hoppers 11 needs to be vibrated and knocked, first remove the first bolt 225 and the second bolt 226 to release the fixation of the limit shaft 214 and the adjustment block 2462, and then move the limit shaft 214 and the fixing block 23 to the required lower hopper 11. At this time, the limit shaft 214 and the fixing block 23 can be automatically fixed by the first bolt 225 and the second bolt 226, and the subsequent vibration work can be carried out.

[0065] A dispensing method of a material dispensing device for blending fertilizers, using the material dispensing device for blending fertilizers, comprises the following steps:

[0066] S1 transports the fertilizers in different batching bins to the conveying pipe through the lower hopper, and then transports them to the subsequent mixing and stirring link through the conveying pipe. When the discharge of the lower hopper is blocked, the vibration motor 2 is started to drive the vibration cam 251 to vibrate and knock the side wall of the lower hopper 11, so that the fertilizer in the lower hopper 11 can be discharged better;

[0067] S2 controls the vibration slide 21 to rotate back and forth around the limit shaft 214 while the vibration cam 251 is striking, and at the same time makes the vibration motor 2 reciprocate on the vibration slide 21, so that the vibration cam 251 can vibrate the side wall of the conical lower hopper 11 in all directions, so that the fertilizer in the lower hopper 11 can be discharged better.
