Abstract
Description
Technical Field
[0001] This utility model provides a crusher, and particularly relates to a ton bag hoisting and bag breaking crusher. Background Technology
[0002] The lifting and breaking of ton bags and the crushing of materials are core steps in the powder and granular materials industry for handling agglomerated materials. In existing technologies, the lifting and breaking equipment and the crushing device are usually independent systems: the lifting equipment (such as electric hoists or cranes) is responsible for moving the ton bags to the breaking station, where the bottom of the ton bag is broken manually or with a simple cutting device. The material is then transferred via conveying equipment (belt conveyors, screw feeders) to a crusher (such as hammer crushers or twin-shaft shears) for secondary crushing. The basic structure of this type of equipment includes a separate lifting unit, an open breaking platform, and an independent crushing unit, requiring multiple devices to work together. Furthermore, most crushers use an open feed inlet and a fixed cutter shaft design, relying on manual feeding or mechanical conveying, making it difficult to directly handle ton bag material.
[0003] The aforementioned separate structure results in a lengthy process flow, requiring multiple hoisting and material transfers, occupying a large space, and necessitating frequent manual intervention, leading to low efficiency. Open-type bag breaking and crushing operations easily generate large amounts of dust, and even with dust collection equipment (such as bag filters), there are still issues with fugitive pollution. The bag breaking device lacks precise positioning and adaptive blade design, easily resulting in incomplete bag breaking and material residue, requiring secondary processing. Furthermore, the height difference and positional deviation between the traditional crusher's feed inlet and the ton bag discharge area cause material accumulation or blockage, affecting processing efficiency. Existing technologies, due to their dispersed structure, poor sealing, and low degree of automation, struggle to achieve efficient and environmentally friendly closed-loop operations for ton bag processing, urgently requiring an integrated solution to overcome these bottlenecks. Utility Model Content
[0004] In order to solve the above problems, this application provides a ton bag hoisting and bag breaking machine, which solves the problems of cumbersome process, dust pollution and low efficiency in traditional processes.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ton bag lifting and crushing machine, comprising an integrated fully sealed frame, an electric hoist suspended from the top of the sealed frame, and a cross-shaped hanger connected below the electric hoist for lifting ton bags of materials; a pneumatic door is provided on the side of the sealed frame, the pneumatic door is opened and closed by a cylinder, and the operation of the electric hoist is linked to the opening and closing of the pneumatic door; an internal cutting device is fixed at the top inside the sealed frame, and a crushing device is provided at the bottom, the internal cutting device being located directly above the crushing device; a discharge port is connected to the bottom of the crushing device, and a dust-blocking brush is provided on the inner wall of the sealed frame for sealing the gap between the electric hoist and the sealed frame; the electric hoist lifts the ton bag of materials to the internal cutting device through the cross-shaped hanger, and the weight of the ton bag of materials cuts through its bottom, causing the material to fall into the crushing device for crushing, and then discharges through the discharge port.
[0006] Preferably, the pneumatic door is opened and closed by the movement of the electric hoist. When the electric hoist moves to the outside of the sealing frame, the pneumatic door opens automatically, and when the electric hoist returns to its original position, the pneumatic door closes automatically.
[0007] Preferably, the dust-blocking brush is arranged around the connection between the electric hoist and the sealing frame to form a dynamic sealing structure.
[0008] Preferably, the internal cutting device includes multiple sets of staggered blades for evenly cutting the bottom of the material ton bag when it is lowered.
[0009] Preferably, the crushing device is a twin-shaft shear crusher, with its input end aligned with the material discharge area of the internal cutter device.
[0010] Preferably, the discharge port is equipped with an adjustable valve to control the discharge speed of the crushed material.
[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0012] This device integrates hoisting, bag breaking, and crushing functions into a single, fully sealed frame, solving the problems of cumbersome processes, low efficiency, and dust pollution caused by the separation of multiple processes in existing technologies. It utilizes an electric hoist linked to the automated control of the pneumatic bin door, simultaneously triggering the opening and closing of the bin door when hoisting material ton bags, achieving one-time hoisting and placement of the ton bags into the bin. A cross-shaped lifting frame precisely lowers the ton bags to the internal cutting device, where gravity breaks the bottom of the ton bag, allowing lumpy materials to fall directly into the crushing device below, eliminating the need for manual handling and secondary operations. The fully sealed frame, combined with a dynamic sealing design using dust-blocking brushes, effectively prevents dust from overflowing during the crushing process. This simplifies the production process, significantly reduces labor and time costs, and achieves dust-free operation, fundamentally improving the working environment and reducing environmental pollution.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] like Figure 1 and Figure 2 As shown, a ton bag lifting and crushing machine includes an integrated fully sealed frame 7, with an electric hoist 1 at the top and a cross-shaped lifting frame 2 at the bottom for lifting ton bags 9. A pneumatic door 3 on the side of the sealed frame 7 is driven by a cylinder to open and close, and is linked to the operation of the electric hoist 1. An internal cutting device 4 is fixed at the top inside the sealed frame 7, and a crushing device 5 is located at the bottom. The internal cutting device 4 is located directly above the crushing device 5, and the bottom of the crushing device 5 is connected to a discharge port 6. Dust-blocking brushes 8 on the inner wall of the sealed frame 7 surround the connection between the electric hoist 1 and the sealed frame 7, forming a dynamic sealing structure. During operation, the electric hoist 1 lifts the ton bag 9 to the internal cutting device 4 via the cross-shaped lifting frame 2. The ton bag 9, under its own weight, cuts through the bottom, and the material falls into the crushing device 5 for crushing. After being crushed, it is discharged through the discharge port 6. The adjustable valve of the discharge port 6 can control the discharge speed of the crushed material.
[0023] In this implementation plan, the integrated fully sealed frame 7 effectively isolates internal dust from escaping through its fully enclosed structure, solving the dust pollution problem caused by open operation of traditional equipment. It also integrates hoisting, bag-breaking, and crushing functions, simplifying equipment layout and saving space. The linkage design between the electric hoist 1 and the pneumatic door 3 synchronizes the opening and closing of the door with the hoisting action of the ton bag through automated control, reducing manual intervention and avoiding efficiency losses due to process separation. The cross-shaped lifting frame 2 precisely positions the material ton bag 9 at its lowering position, ensuring that its bottom contacts the internal cutting device 4, using the ton bag's own weight to cut the bag, replacing traditional manual bag-breaking operations. This significantly reduces labor intensity and safety risks. The internal cutting device 4 uses a multi-set staggered blade design to evenly cut the bottom of the ton bag, avoiding material residue or incomplete local damage. The crushing device 5 directly receives the falling clumps of material and efficiently crushes them through a dual-axis shearing structure, shortening the material handling path and improving overall production efficiency. The adjustable valve of the discharge port 6 can flexibly control the material discharge speed according to the needs of subsequent processes, avoiding blockage and optimizing the production rhythm. The dust-blocking brush 8 dynamically fits the frame gap when the electric hoist 1 moves, forming a double sealing barrier to further suppress dust emission and ensure a dust-free working environment. The synergistic effect of each structure realizes an integrated process of hoisting, bag breaking, and crushing, which not only simplifies operation steps and reduces labor and time costs, but also completely solves the core problems of serious environmental pollution and low efficiency in traditional processes through a fully sealed design and dynamic dust prevention technology, significantly improving production economy and environmental protection.
[0024] like Figure 2 and Figure 3 As shown, it is also worth noting that the pneumatic door 3 of the ton bag lifting and crushing machine is triggered by the movement of the electric hoist 1. When the electric hoist 1 moves to the outside of the sealing frame 7, the pneumatic door 3 automatically opens, and when the electric hoist 1 returns to its original position, the pneumatic door 3 automatically closes. The internal cutting device 4 contains multiple sets of staggered blades, which can evenly cut the bottom of the ton bag 9 when it is lowered. The crushing device 5 uses a twin-shaft shear crusher, and its input end is precisely aligned with the material drop area of the internal cutting device 4 to ensure the high efficiency and stability of material crushing.
[0025] In this implementation scheme, the pneumatic door 3 uses a standard SMCCDQ2B cylinder as its drive system, with a working pressure range of 0.5-0.7MPa and a stroke of 500mm based on the frame dimensions. The door is made of 304 stainless steel (5mm thick). A magnetic switch is used in conjunction with the displacement sensor of the electric hoist 1 to achieve precise synchronization between door opening / closing and lifting actions. The electric hoist 1 is a CD1 type wire rope electric hoist with a rated load of 2 tons, a lifting speed of 8m / min, and a motor power of 3kW, ensuring efficient and stable lifting. The cross-shaped lifting frame 2 is welded from Q235 carbon steel, with a crossbeam size of 1200mm × 800mm and a hook load capacity of 2.5 tons. It is galvanized to enhance corrosion resistance. The internal cutting device 4 uses high-carbon tool steel SK5 (hardness HRC58-62) blades. Each set of blades... The crushing unit consists of 4 blades arranged in 3 groups, with a blade spacing of 50mm and a staggered angle of 30° to ensure uniform cutting and no residue at the bottom of the ton bag. The crushing device 5 is a twin-shaft shear crusher with a motor power of 22kW, a cutter shaft speed of 30rpm, and a blade diameter of φ400mm (made of Cr12MoV alloy steel). It has a processing capacity of 10 tons / hour, and the distance between the input end and the material discharge port of the cutting device is ≤200mm to ensure seamless material connection. The adjustable valve of the discharge port 6 is a pneumatic gate type with a diameter of DN300 and a valve plate material of 316L stainless steel. The adjustment range is 0-100%, and the discharge speed is precisely adjusted through PLC control. The dust-blocking brush 8 is made of nylon filaments with a density of 200 filaments / cm². It is installed at the top of the frame and at the connection with the electric hoist. The brush is 50mm long and dynamically fits the gap between the brush and the frame, achieving a dust blocking efficiency of ≥95%.
[0026] The selection of the aforementioned quantitative parameters and standardized components ensures that each structure achieves optimal functional adaptability, durability, and compatibility: the high-precision linkage of the pneumatic chamber door reduces human intervention errors, the efficient shearing of the twin-shaft crusher shortens material handling time, adjustable valves match different working conditions, and standardized models simplify equipment maintenance and spare parts replacement processes. Through parametric design and the integration of industrial-grade components, this device further enhances the reliability and large-scale application potential of the equipment while ensuring automated and dust-free operation.
[0027] In the above implementation scheme, the implementation of this device is based on the system integration and optimization of existing technical solutions: During installation, the integrated fully sealed frame is fixed to a concrete foundation or steel structure platform, and the track support of the electric hoist is fixed at the top with high-strength bolts to ensure that the hoisting path is aligned with the central axis of the frame; the cylinder of the pneumatic door is connected to the pre-installed mounting seat on the side of the frame through a flange, and its solenoid valve group is electrically connected to the displacement sensor of the electric hoist to realize the real-time triggering of the door opening and closing by the hook displacement signal; the blade assembly of the internal cutting device is fixed to the top crossbeam of the frame through a detachable slot, and the blade... The spacing and angle of the blades are finely adjusted using positioning pins to ensure they match the trajectory of the ton bag's descent. The dual-shaft shear of the crushing unit is installed at the bottom of the frame via a shock-absorbing base. Its feed inlet and the material drop area of the cutting device are seamlessly connected by a funnel-shaped guide plate. The guide plate is designed with a 60° inclination angle to accelerate material sliding. The gate valve at the discharge port is linked to the PLC via a pneumatic actuator. The operating interface has preset three flow rate modes: "fast / medium / slow". The dust-blocking brush is embedded in the annular groove at the top of the frame via a stainless steel pressure strip. The gap between the brush and the electric hoist hook is kept dynamically fitted by a spring pre-tightening mechanism. During operation, the operator starts the electric hoist via the control panel. The hook moves outward, triggering the hopper door to open. After the forklift hangs the ton bag on the cross-shaped lifting frame, the hook returns to its original position, pulling the ton bag into the hopper and triggering the hopper door to close. During the ton bag's descent, gravity drives the cutter to break the bottom. The material then enters the crusher's dual-shaft blades through the guide plate for shearing and crushing. After crushing, the material is discharged through the discharge valve at a set speed. Throughout the process, dust is effectively blocked by the frame seal and brushes. Residual dust is collected by a bag filter at the top of the frame. Each step utilizes standardized interfaces of existing industrial components for rapid assembly and maintenance, forming a complete closed-loop operation system from ton bag hoisting, automatic bag breaking, sealed crushing to dust-free emission.
[0028] The operating steps of this device are as follows: The operator starts the electric hoist 1 via the control panel, moving it to the outside of the sealed frame 7. At this time, the displacement sensor of the electric hoist 1 triggers the cylinder switch of the pneumatic door 3, and the door opens automatically. The forklift hangs the material ton bag 9 on the cross-shaped lifting frame 2 below the electric hoist 1. The electric hoist 1 is then operated to return to its original position, and the ton bag enters the sealed frame 7 along with the lifting frame. The reset signal of the electric hoist 1 triggers the pneumatic door 3 to close, achieving a complete seal of the frame. Subsequently, the electric hoist 1 controls the ton bag 9 to be lowered to the internal cutting device 4, utilizing the ton bag's own weight. The bottom of the bag is brought into contact with the staggered blades, which evenly cut the bag. The lumpy material falls directly into the crushing device 5 below, where the dual-axis shearing blades efficiently crush the material. The crushed material is discharged to the next process through the adjustable valve of the discharge port 6 at a preset speed. Throughout the process, the dust-blocking brush 8 dynamically fits the gap between the electric hoist 1 and the frame 7, and works with the sealing frame to prevent dust from overflowing. The residual dust is collected through the top dust collection port and then connected to an external bag filter for centralized treatment. This process achieves fully automated closed-loop operation of ton bag hoisting, bag breaking, crushing, and dust-free discharge.
[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
