DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] In modern industrial production, the unloading and sorting of bagged materials are important links in many production processes. The traditional manual unloading method is not only inefficient, but also has many safety risks. At the same time, the dust pollution generated during unloading also poses a serious threat to the environment and the health of workers. The bagged material 1 automatic unloading and sorting device of the utility model effectively solves these problems with its innovative design and unique functions, bringing higher efficiency and better environmental friendliness to industrial production.

[0023] As Figure 1 shown, the core part of the bagged material 1 automatic unloading and sorting device is wrapped by the machine cover, which provides a relatively closed space for the internal unloading and sorting work. The machine cover adopts a rectangular sealed cover design, which is crucial. It can effectively prevent dust from escaping, greatly improving the working environment and reducing pollution to the surrounding environment.

[0024] As Figure 1 and Figure 3As shown, one side of the housing is provided with a material inlet door, which is the entrance of the bagged material into the device. At the top of the inner wall of the housing, a transport rail 12 extends across and protrudes from the material inlet door. The transport rail 12 is like a "highway" for the conveyance of the lifting head 4, which is responsible for lifting the bagged material 1 into the device. The lifting head 4 is mounted on the transport rail 12 by a number of traversing wheels 4.1 at the top of the lifting head 4. Two traversing wheels 4.1 are arranged on both sides of the transport rail 12 to ensure the stability of the lifting head 4. Fixed baffles 4.2 are arranged outside the traversing wheels 4.1 to prevent the traversing wheels 4.1 from derailing during operation.

[0025] A negative pressure suction duct 6 is provided at the top of the housing, which is responsible for sucking the dust generated during the unloading and vibrating screening process through the negative pressure suction duct 6 to an external dust collector for collection and treatment. During the unloading and vibrating screening process, the dust generated during the operation of the device is quickly collected and transported to the external dust collector for treatment under the action of negative pressure through the high-efficiency suction of the suction duct. An adjustable damper is arranged at the inlet of the suction duct, which can adjust the air volume according to the actual working condition to achieve the best dust removal effect. The external dust collector adopts a high-efficiency filter cartridge design and is equipped with a pulse backflushing ash removal system, which can effectively separate and collect dust particles to ensure that the exhaust gas meets the environmental protection standards. Inside the housing, below the transport rail 12, the sorting screen 8 assembly occupies an important position, which is the key component for material sorting. Above the sorting screen 8 assembly, a bag breaking cone 7 with a pointed end upward is arranged, which is responsible for cutting the bagged material 1.

[0026] As shown in Figure 2 As shown in Figure 2As shown, the bag breaking cone 7 is installed on the fixed beam above the sorting screen 8 assembly through the fixed seat 7.2. The fixed beam is horizontally arranged along the middle part of the machine cover cross section, and the center line thereof is completely coincident with the symmetry axis of the machine cover cross section, so that the bag breaking cone 7 is uniformly stressed during work. The bag breaking cone 7 is specifically arranged at the middle part of the fixed beam, and the installation position thereof is accurately calculated, so that the bag breaking efficiency is maximally improved. The bag breaking cone 7 adopts a hollow triangular pyramid structure design with a pointed end upward, which is composed of a cone frame and a bottom fixed seat 7.2. The cone frame is a hollow triangular pyramid structure which is welded by a plurality of blade 7.1 with outward blades, and three blade 7.1 are evenly distributed at 120° to form a stable triangular pyramid frame in the embodiment. The blade 7.1 is made of high-strength alloy steel and has excellent wear resistance and impact resistance after special hardening treatment of the surface. The bottom fixed seat 7.2 is a triangular frame structure which is firmly connected with the fixed beam through bolts to ensure the stability of the bag breaking cone 7 during work. The whole bag breaking cone 7 adopts a hollow design, which not only reduces the overall weight and the energy consumption of the equipment operation, but also facilitates the smooth passage of the crushed materials and improves the material processing efficiency. In addition, the structural design of the bag breaking cone 7 fully considers the maintenance convenience, and the blade 7.1 is detachably installed to facilitate the replacement and maintenance in the later period, thereby effectively prolonging the service life of the equipment.

[0027] When the bagged material 1 is hoisted by the hoisting head 4 to the upper side of the bag breaking cone 7, the bagged material 1 will gradually approach the bag breaking cone 7 with the movement of the hoisting head 4. The blade 7.1 outwardly arranged on the bag breaking cone 7 is like a sharp pair of scissors which accurately cuts the bag. The reasonable layout of the bag breaking cone 7 enables it to efficiently cut the bagged material 1 and ensure that the material smoothly falls into the sorting screen 8 below. Since the bag breaking cone 7 is composed of common blade 7.1 and frame, it is convenient for production and is very suitable for mass production, which greatly reduces the production cost. Moreover, the hollow design of the bag breaking cone 7 can reduce its own weight without affecting its bag breaking function, thereby further improving its cost performance.

[0028] As shown in Figure 1 , the sorting screen 8 assembly mainly includes the sorting screen 8, and the sorting screen 8 is provided with a mesh at the bottom and a vibrator 3 at the side. In actual production, different sizes of mesh can be flexibly configured according to different production process requirements. For example, when processing some materials with larger particles, a sorting screen 8 with larger mesh can be selected; and when processing fine materials, a sorting screen 8 with smaller mesh can be replaced.

[0029] When the material falls into the sorting screen 8 from the bag breaking cone 7, the vibrator 3 begins to work. The vibration generated by the vibrator 3 can make the material jump and roll on the sorting screen 8 continuously. The large particle material cannot pass through the mesh, and will gradually move to the oversize outlet 9 under the action of vibration, and finally be discharged through the oversize outlet 9. Subsequently, these large particle materials can be transferred to the designated location by a loader or other equipment. The small particle material will pass through the mesh at the bottom of the sorting screen 8 and fall into the material box 10 through the discharge hopper 14. The sorting screen 8 assembly realizes efficient separation of large and small particle materials through the vibration function of the vibrator 3, greatly improving the separation precision and efficiency. At the same time, according to the design of different mesh sizes configured according to different production process requirements, the versatility and flexibility of the device are enhanced, which can meet the sorting needs of various materials.

[0030] The machine cover is provided with an oversize outlet 9 at the outlet of the sorting screen 8, and the bottom of the oversize outlet 9 is provided with a discharge plate. The discharge plate is inclined downward, and the top end is closely connected with the outlet of the sorting screen 8. When the large particle material reaches the oversize outlet 9, the inclined discharge plate acts like a slide, guiding the large particle material to be discharged smoothly. This design can avoid the accumulation or blockage of the material at the outlet, improving the efficiency and reliability of the material transfer. At the same time, due to the blocking effect of the discharge plate, the risk of dust leakage is reduced, further optimizing the working environment.

[0031] The sorting screen 8 is provided with a discharge hopper 14 below, and the upper and lower ends of the discharge hopper 14 are open. The upper end opening covers the bottom surface of the sorting screen 8. The lower end opening of the discharge hopper 14 is smaller than the upper end opening. Such a structural design helps to concentrate the collection of materials and avoid the scattering of materials during the discharging process. After the small particle material falls into the discharge hopper 14 through the mesh, it will be guided by the discharge hopper 14 and fall into the material box 10 below smoothly. The material box 10 is placed on the tray 11 at the bottom end of the machine cover, and the machine cover is provided with a discharge door 2 at the front of the material box 10.

[0032] During the unloading and vibrating screening process, a certain amount of dust will inevitably be generated. At this time, the negative pressure air suction pipeline 6 begins to work, which can suck the dust to the external dust collector for collection and treatment. The design of the discharge hopper 14 not only can effectively collect small particle materials, prevent materials from scattering, ensure that materials fall into the material box 10 smoothly, improve the material collection efficiency, but also can reduce material waste and reduce production cost. The combined action of the sealed machine cover and tray 11 design, as well as the reasonable layout of the material box 10 and the setting of the discharge door 2, makes the transfer and management of materials more convenient, and improves the overall production efficiency.

[0033] As Figure 3As shown, the lifting head 4 is provided with a power source below the transverse wheel 4.1, and the power source is a driving motor 4.4, and a hook 4.3 is arranged below the power source. The bagged material 1 is lifted by the lifting head 4 into the machine cover, and the hook 4.3 is used to hook the bagged material 1 below. When it is necessary to unload, the operator starts the driving motor 4.4, the driving motor 4.4 drives the transverse wheel 4.1 to move on the transportation rail 12, so that the lifting head 4 can be accurately moved to the position of the bagged material 1. Then, by controlling the driving motor 4.4, the hook 4.3 is lowered to hook the bagged material 1, and then the bagged material 1 is lifted to above the bag breaking cone 7 in the machine cover. One end of the transportation rail 13 is fixed on the platform through a support 13, and the design of the power source and the hook 4.3 enables the lifting head 4 to efficiently and stably lift the bagged material 1, reduces the cumbersome operation of manual carrying, further improves the unloading efficiency, and reduces the labor intensity and safety risk.

[0034] Working process.

[0035] In actual work, first, the bagged material 1 is placed in a position accessible to the hook 4.3 of the lifting head 4. The operator starts the driving motor 4.4 through the control system, the lifting head 4 moves above the bagged material 1 on the transportation rail 12, the hook 4.3 is lowered to hook the bagged material 1, and then the bagged material 1 is lifted to above the bag breaking cone 7 in the machine cover. With the movement of the lifting head 4, the bagged material 1 contacts the bag breaking cone 7, the blades 7.1 on the bag breaking cone 7 cut the bag, and the material falls into the below sorting screen 8.

[0036] On the sorting screen 8, the vibrator 3 starts to work, and the large-particle material moves to the oversize outlet 9 under the action of vibration, and is finally discharged through the oversize outlet 9 and the discharge plate, and is transferred by a loader or the like. The small-particle material falls into the discharge hopper 14 through the mesh at the bottom of the sorting screen 8, and then enters the material box 10. The dust generated in the whole process is sucked into an external dust remover by the negative pressure suction pipeline 6 for treatment. When the material box 10 is full, the operator can use a forklift to transfer the material box 10 placed on the pallet 11 to a designated place through the discharge door 2 in the front of the machine cover.

[0037] The metal sorting device is suitable for multiple industries, including environmental protection, metallurgical slag and the like. For example, in a chemical raw material production enterprise, the manual unloading in the past is not only low in efficiency, but also has certain safety risks due to the particularity of the chemical raw material, and the dust generated in the unloading process greatly harms the environment and the health of workers. After the device is adopted, the unloading efficiency is greatly improved, the unloading work originally completed by a plurality of people in a large amount of time can now be easily completed by a small number of operators through a control system. Moreover, due to the efficient bag breaking of the bag breaking cone 7 and the accurate sorting of the sorting screen 8 assembly, the waste of the material is obviously reduced, and the production cost is reduced. At the same time, the design of the negative pressure suction pipeline 6 and the sealed machine cover greatly improves the working environment, and effectively solves the dust pollution problem.

[0038] In the grain processing industry, the device also plays an important role. In the unloading and sorting process of grain, the influence of dust flying on the quality of grain is avoided, and the purity of grain is ensured. Moreover, according to the design of flexible replacement of the mesh size of the sorting screen 8 according to the size of different grain particles, the sorting requirements of different grains are met, and the efficiency and quality of grain processing are improved.

[0039] The bagged material automatic unloading and sorting device has the characteristics of compact structure, high efficiency and small environmental pollution, so that it has good use effect in the actual production process.

[0040] Obviously, the above embodiments are only examples for clearly illustrating, and are not limited to the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
