Description

Technical Field

[0001] The invention relates to the technical field of fertilizer making equipment, in particular to a bag breaking and feeding system for blended fertilizer production. Background Art

[0002] Blended fertilizer is a dry-mixed fertilizer, which is a fertilizer containing any two or three of the three nutrient elements of nitrogen, phosphorus and potassium, and is made by mixing unit fertilizer or compound fertilizer as raw materials. The existing production of blended fertilizer adopts dry mixing of fertilizers of three nutrient elements, for example, CN214931326U discloses a bag breaking and feeding system for blended fertilizer production, and the contents disclosed in paragraphs

[0026] to

[0028] of the specification are as follows: the material bag pierced by the bag breaking blade enters the raw material hopper, and the material falls from the vibrating screen, and the packaging bag is located above the vibrating screen, which is convenient for the staff to pick up. The packaging bag is shaken up and down by a vibrating screen to shake out the fertilizer inside the packaging bag. This shaking-out efficiency is not high and some fertilizer will remain inside (especially at the bag openings at both ends). The packaging bag is isolated in the upper layer by a vibrating screen. An additional person is required to be responsible for picking up the packaging bag in time. If the packaging bag is not picked up in time, the vibrating screen will be blocked. If it is picked up too quickly, the amount of fertilizer remaining inside will be large. If it is picked up too slowly, it will easily cause blockage or subsequent fertilizer will enter the previous packaging bag, which makes the employee's workload larger. Summary of the invention

[0003] The purpose of the present invention is to solve the problem in the prior art that the vibrating screen shakes the packaging bag and it is easy for fertilizer residues to remain in the bag, and an additional person needs to be assigned to pick up the packaging bag, which brings a heavy workload. Therefore, a bag breaking and feeding system for blended fertilizer production is proposed. The packaging bag is automatically picked up by a bag picking mechanism, and there is no need to be equipped with a vibrating screen. Gravity is used to clean the fertilizer inside the bag during the automatic picking process of the bag, thereby achieving efficient bag breaking and feeding.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A bag breaking and feeding system for blended fertilizer production, comprising:

[0006] A conveying mechanism, which is suitable for conveying bagged raw materials;

[0007] Bag breaking mechanism, which is suitable for cutting and breaking material bags;

[0008] The feeding mechanism is suitable for automatically feeding the raw materials leaking out after the material bag is cut;

[0009] The material bag picking mechanism is suitable for automatic picking up of material bags;

[0010] The material bag picking mechanism includes a frame located above the conveying mechanism and the feeding mechanism, the frame is provided with a conveying chain, the conveying chain is provided with a picking component and a self-locking component, the picking component is suitable for hooking the material bag, and the self-locking component is suitable for self-locking the picking component before hooking the material bag and automatically releasing the self-locking of the picking component after hooking the material bag.

[0011] The bagged raw materials are transported by the conveying mechanism and transported to the bag breaking mechanism for opening the bag. The bag picking mechanism automatically hooks the bag under the conveying action of the conveying mechanism before the bag opens. At the same time, the locking state of the self-locking component is released by the conveying inertia. When the bag leaves the conveying mechanism, the bag is suspended and hooked by the picking component. When passing over the feeding mechanism, the fertilizer inside the bag will be directly discharged from the inside of the bag by gravity. The subsequent picking component completes self-locking under the action of the corresponding self-locking component and waits for the subsequent bagged raw materials transported by the conveying mechanism. Due to the sudden self-locking of the subsequent self-locking component, the bag hooked by the former picking component can swing to accelerate the discharge of fertilizer.

[0012] In a further preferred solution, the picking assembly includes a mounting seat fixedly mounted on the conveying chain, a swing rod is rotatably mounted on the mounting seat, a hooking member suitable for hooking a material bag is mounted on the bottom of the swing rod, the self-locking assembly includes a swing arm rotatably mounted on the mounting seat and a flexible locking member mounted on the swing arm, a guide ring groove suitable for guiding the flexible locking member and a locking groove arranged on the guide ring groove and adapted to the flexible locking member are arranged on the frame, the swing rod is located on the outside of the conveying chain, and the swing arm is located on the inside of the conveying chain. The guide ring groove can always keep the flexible locking member on the inside of the conveying chain for directional movement. And a reversing groove is arranged on the guide ring groove for automatic reversing of the flexible locking member. When the front side flexible locking member is in the locking groove to form a locking effect, the conveying chain stops working, and the subsequent flexible locking member will complete the reversal along the reversing groove under the action of its own gravity, and the flexible locking member will be turned from the rear side of the mounting seat to the front side, providing necessary conditions for the subsequent self-locking effect.

[0013] The material bag is automatically hooked by the hook part at the bottom through the rotation arrangement of the swing arm relative to the mounting seat. When hooking, the mounting seat will move backward and squeeze the flexible locking part until the mounting seat passes through the locking groove. At the same time, the flexible locking part will move in the opposite direction and follow the mounting seat through the locking groove. The subsequent flexible locking part will first enter the locking groove to lock the conveying chain. At this time, the front hook hanging part suspends the material bag in the middle position above the feeding mechanism. Due to the sudden locking of the subsequent flexible locking part, the front hook hanging part will swing the material bag back and forth to ensure that all the fertilizer is discharged.

[0014] In a further preferred embodiment, the hook member comprises a mounting body and a hook body, the mounting body is rotatably mounted on an outer end of the swing rod, and the hook body is rotatably mounted on a middle portion of the mounting body.

[0015] By hooking the material bag with more than two sets of hooks (corresponding to two sets of conveyor chains), the material bag can be prevented from swinging left and right, and at the same time, creases are easily formed on the bottom of the material bag when one set of hooks is used, which makes it inconvenient for fertilizer discharge.

[0016] In a further preferred solution, the hook body comprises a main body mounted on the mounting rod and a hook body partially mounted inside the main body, and the hook body inside the main body is connected to the main body via a spring. The hook body adopts a flexible structure to reduce the instantaneous impact force of the bag on the hook body, and can increase the shaking frequency of the bag when entering the hanging bag.

[0017] In a further preferred solution, the flexible locking member includes a movable member slidably mounted near the top of the swing arm, the movable member and the swing arm are flexibly mounted via a spring, a roller is mounted on the movable member and the roller fits into the wire ring groove. The movable member is connected to the swing arm using a spring, so that the rigid impact of the instantaneous release of the locking state of the hooked bag can be reduced, and the swing amplitude of the hanging bag can be increased to ensure that all the fertilizer inside is discharged.

[0018] In a further preferred embodiment, the conveying mechanism comprises an inclined chute, the bag breaking mechanism comprises a blade arranged at a position of the chute close to the feeding mechanism, and the feeding mechanism comprises a containing box and a screw conveyor arranged at the bottom of the containing box.

[0019] In a further preferred embodiment, the system further comprises a material bag collecting mechanism, which is arranged at the tail end of the material bag picking mechanism, and comprises a collecting body and a scraper installed on the collecting body, wherein the scraper is provided with a slot for a hook to pass through.

[0020] When the hook member passes through the scraper, it first enters the inside of the slot, and due to the blocking effect of the scraper, the material bag is hooked and broken under the action of resistance, and the material bag remains in the collection body.

[0021] In a further preferred solution, the scraper comprises a fixed part and a rotating part rotatably mounted below the fixed part, and a plurality of spikes are arranged on the bag-facing side of the rotating part. The spikes on the bag-facing side of the rotating part can increase the resistance of the scraper, so that the bag can be separated from the hook more easily.

[0022] In a further preferred solution, a negative pressure collection assembly is provided inside the collection body, and the nail teeth are inclined toward the negative pressure collection assembly. When in use, the material bag is easily retained on the nail teeth, and the negative pressure collection assembly can automatically separate the material bag from the nail teeth on the rotating part and enter the collection body for unified treatment.

[0023] The production process of blended fertilizer adopts the above-mentioned bag breaking and feeding system, and the production steps are as follows:

[0024] S100: The bagged raw materials are placed from the top of the chute by a robot, and the bagged raw materials slide down the chute. The kinetic energy increases with the increase of the sliding distance.

[0025] S200: After the bagged raw material is hooked with the hook, the hook is first driven to be transported to the upper feeding mechanism, and at the same time, the flexible locking member is squeezed, and the mounting seat is rotated from the front side of the flexible locking member to the rear side, and the locking effect of the flexible locking member is released, and the power of the conveying chain is input and works, and the hook and the bagged raw material are transported to the upper feeding mechanism together;

[0026] S300: The bagged raw material forms at least one opening at the place where it passes through the bag breaking mechanism;

[0027] S400: After the material bag enters the upper area of ​​the feeding mechanism, it is suspended by the hooking member. The flexible locking member enters the locking groove to form a sudden lock. The opened material bag swings back and forth, and the fertilizer is unpacked and put into the storage box. The screw conveyor quantitatively transports the fertilizer to the next station for mixing, bagging and packaging.

[0028] The material bags that have completed the stripping will enter the material bag collection station, and the hook will enter the slot first. As the hook continues to transport the hooked material bags, they will be caught by the nail teeth on the rotating part to increase the resistance to passing through. The material bags will be torn by the hook, and under the action of the negative pressure collection component, they will enter the bottom inner side of the collection body for unified collection and processing.

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] Embodiment 1, as Figures 1 to 6 As shown, a bag breaking and feeding system for blended fertilizer production includes: a conveying mechanism 10, the conveying mechanism 10 includes an inclined chute, and the conveying mechanism 10 is suitable for conveying bagged raw materials; a bag breaking mechanism 20, the bag breaking mechanism 20 includes a blade arranged at a position of the chute close to a feeding mechanism 30, and the bag breaking mechanism 20 is suitable for cutting and breaking material bags; a feeding mechanism 30, the feeding mechanism 30 includes a containing box and a screw conveyor 31 arranged at the bottom of the containing box, and the feeding mechanism 30 is suitable for automatically feeding the raw materials leaked out after the material bags are cut.

[0047] A material bag picking mechanism 40, the material bag picking mechanism 40 is suitable for automatically picking up material bags;

[0048] like Figure 4 As shown, the material bag picking mechanism 40 includes a frame 41 located above the conveying mechanism 10 and the feeding mechanism 30, and a conveying chain 42 is arranged on the frame 41. The conveying chain 42 is provided with a picking component and a self-locking component. The picking component is suitable for hooking the material bag, and the self-locking component is suitable for self-locking the picking component before hooking the material bag and automatically releasing the self-locking of the picking component after hooking the material bag.

[0049] like Figure 4 As shown, the picking assembly includes a mounting seat 43 fixedly mounted on the conveying chain 42, a swing rod 44 is rotatably mounted on the mounting seat 43, a hook 45 suitable for hooking a bag is mounted at the bottom of the swing rod 44, the self-locking assembly includes a swing arm 46 rotatably mounted on the mounting seat 43 and a flexible locking member mounted on the swing arm 46, and a guide ring groove 48 suitable for guiding the flexible locking member and a locking groove 47 (such as a locking groove 47) arranged on the guide ring groove 48 and adapted to the flexible locking member is provided on the frame 41. Figure 4 As shown), the guide ring groove 48 is provided with a reversing groove 49 suitable for automatic reversing of the flexible locking member (as shown Figure 2 As shown in the figure, the swing rod 44 is located on the outside of the conveying chain 42, and the swing arm 46 is located on the inside of the conveying chain 42. When the front side flexible locking member is in the locking groove to form a locking effect, the conveying chain stops working, and the flexible locking member located in the subsequent direction will complete the reversal along the reversing groove under the action of its own gravity, and the flexible locking member will be turned from the rear side of the mounting seat to the front side, providing the necessary conditions for the subsequent self-locking effect. After the flexible locking member completes the reversal, when the mounting seat 43 faces the conveying mechanism 10, the swing arm 46 will abut against the top of the swing rod 44, and the flexible locking member will be flexibly deformed at this time, so that it can directly enter the locking groove 47 when it is adapted to the locking groove 47 later.

[0050] like Figure 5 As shown, the hook member 45 includes a mounting body 451 and a hook body 452. The swing rod 44 is provided with two hooks respectively located on both sides of the mounting seat 43. The mounting body 451 is rotatably mounted on the outer end of the swing rod 44, and the hook body 452 is rotatably mounted on the middle part of the mounting body 451. Two groups of hook bodies 452 are provided, and the conveying chain 42 is also provided with two groups.

[0051] The bagged raw materials are put into the chute from the top by the manipulator, and the bagged raw materials will slide down the chute. The kinetic energy of the sliding speed will increase appropriately as the sliding distance increases, and then the hook body 452 staying in the original position will hook the material bag. At the same time, because the material bag has a certain kinetic energy, the flexible locking member will be separated from the locking groove 47 to release the locking state, and the conveying resistance of the conveying chain 42 will be reduced to a preset value range. After that, the material bag will be conveyed to the storage box along the chute by the conveying chain 42. During the conveying process, the bottom of the material bag will be broken by the blade to form one or more openings. When the material bag enters the top area of ​​the storage box, it will be suspended. The fertilizer inside will move toward the opening (the opening will increase appropriately and the bag at the opening will naturally droop) and be discharged from the opening. When the bag is suspended and transported to the middle of the upper part of the storage box, the subsequent flexible locking member will enter the locking groove 47 and suddenly form a self-locking state. The conveying chain 42 stops working due to the increase of conveying resistance. At this time, the bag will swing back and forth due to its own inertia, accelerating and or strengthening the speed and effect of removing the bag of the internal fertilizer, ensuring that the internal fertilizer is quickly and completely removed from the bag and enters the storage box at the bottom. Finally, the fertilizer will be transported to the next process through the screw conveyor 31. The conveying resistance of the conveying chain 42 is realized by adding a torque sensor at the power input end to realize the free switching between power input and cutoff.

[0052] Embodiment 2 makes the following improvements based on the above embodiment: Figure 6 As shown, the hook body 452 includes a main body installed on the installation body 451 and a hook body partially installed inside the main body, and the hook body inside the main body is connected to the main body through a spring.

[0053] The hook body and the main body are flexibly connected via a spring, so that when the material bag is suspended and swings back and forth, it can also vibrate up and down to improve the fertilizer bag removal effect. At the same time, when hooking the bagged raw materials, the impact of the material bag on the hook body 452 is reduced, and the two can be prevented from being directly rigidly hooked, which may lead to easy unhooking.

[0054] Embodiment 3 makes the following improvements on the basis of the above embodiment: Figures 2 to 4 As shown in FIG. 1 , the flexible locking member includes a movable member 461 slidably mounted near the top of the swing arm 46. The movable member 461 and the swing arm 46 are flexibly mounted via a spring. A roller 462 is mounted on the movable member 461 and the roller 462 fits into the guide ring groove 48. After the flexible locking member completes the reversal, when the mounting seat 43 faces the conveying mechanism 10, the swing arm 46 will abut against the top of the swing rod 44, as shown in FIG. Figure 3As shown, at this time, the roller 462 of the flexible locking member will drive the movable member 461 to compress the spring under the action of the guide ring groove 48. When entering the locking area, the spring will drive the movable member 461 and the roller 462 to move toward the locking groove 47, and the mounting seat 43 will continue to move backward for a short distance. At the same time, the swing arm 46 will rotate forward for a certain distance, thereby re-compressing the spring. When the conveying resistance of the conveying chain 42 is greater than the preset value range, the angle between the swing arm 46 and the conveying direction is an acute angle to ensure self-locking.

[0055] When the movable member 461 is transported backward without load, it will first enter the locking groove 47, and the transport resistance of the conveying chain 42 will be gradually increased due to the action of the spring (such as Figure 4 As shown), when it exceeds the preset value range, the power is disconnected, and when the bagged raw material slides down from the chute to this point, it moves toward the storage box together with the hook body, and the mounting seat passes through the locking groove 47, and then the movable part 461 is turned from the rear side to the front side and continues to be transported to the rear side through the locking groove 47 to the upper area of ​​the storage box for hanging, and the fertilizer is discharged from the opening of the bag, and the movable part 461 transported subsequently enters the locking groove 47 without load and repeats the above action.

[0056] Embodiment 4 makes the following improvements on the basis of the above embodiments. The system also includes a material bag collecting mechanism 50, which is arranged at the tail position of the material bag picking mechanism 40. The material bag collecting mechanism 50 includes a collecting body 51 and a scraper 52 installed on the collecting body 51. The scraper 52 is provided with a slot 53 for the hook 45 to pass through. The front side of the collecting body 51 is provided with a material bag inlet. The scraper 52 includes a fixed portion 521 and a rotating portion 522 rotatably installed below the fixed portion 521. A plurality of spikes are provided on the bag-facing side of the rotating portion 522. The rotating portion 522 is located at the material bag inlet. A negative pressure collecting assembly 54 is provided inside the collecting body 51, and the spikes are inclined toward the negative pressure collecting assembly 54.

[0057] When the hook 45 passes through the scraper 52, it first enters the slot 53. Due to the blocking effect of the scraper 52, the bag is hooked and torn under the resistance, and the bag remains in the collection body. After the scraper 52 enters the slot 53, the nail teeth on the bag-facing side of the rotating part 522 increase its passing resistance, ensuring that the bag is hooked and torn. At the same time, the negative pressure collection component 54 (exhaust device) inside the collection body 51 is cooperated to collect the bag into the collection body 51.

[0058] The production process of blended fertilizer adopts the bag breaking and feeding system as described above, and the production steps are as follows:

[0059] S100: The bagged raw materials are placed from the top of the chute by a robot, and the bagged raw materials slide down the chute. The kinetic energy increases with the increase of the sliding distance.

[0060] S200: After the bagged raw material is hooked with the hook member 45, the hook member 45 is first driven to be transported to the upper feeding mechanism 30, and at the same time, the flexible locking member is pressed, and the mounting seat 43 is rotated from the front side of the flexible locking member (roller 462) to the rear side, and the locking effect of the flexible locking member is released, and the power of the conveying chain 42 is input and works, and the hook member 45 and the bagged raw material are transported to the upper feeding mechanism 30 together;

[0061] S300: The bagged raw material forms at least one opening at the bag breaking mechanism 20;

[0062] S400: After the material bag enters the upper area of ​​the feeding mechanism 30, it is suspended by the hook member 45. The flexible locking member enters the locking groove 47 to form a sudden lock. The opened material bag swings back and forth, and the fertilizer is unpacked and enters the storage box. The screw conveyor 31 quantitatively conveys the fertilizer to the next station for mixing, bagging and packaging.

[0063] The material bags that have completed the stripping will enter the material bag collection station, and the hook member 45 will first enter the slot 53. As the hook member 45 continues to transport the hooked material bags, they will be caught by the nail teeth on the rotating part 522 to increase their passing resistance. The material bags are torn by the hook member 45 and enter the inner bottom of the collection body 51 under the action of the negative pressure collection component 54 for unified collection and processing.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The replacement may be a replacement of a part of the structure, device, method step, or a complete technical solution. Any equivalent replacement or change according to the technical solution and the inventive concept of the present invention shall be covered within the protection scope of the present invention.
