Description

Technical Field

[0001] This utility model relates to the technical field of sodium metasilicate production equipment, and in particular to a fully automatic walking crushing equipment. Background Technology

[0002] Sodium metasilicate is an inorganic silicate material widely used in detergents, ceramics, papermaking, water treatment, and other fields. Its production process typically involves using a liquid sodium silicate solution as raw material, which is physically cooled and then released into a specially designed large metal tank. As the solution continues to cool to a specific temperature within the tank, a chemical reaction occurs, releasing a large amount of heat, and ultimately solidifying instantly into a tough crystalline solid. The material exhibits significant viscosity at high temperatures (before complete solidification), easily adhering to contact surfaces. Simultaneously, its chemically active nature, containing reactive silicate components, makes it corrosive to metals, skin, and other contact surfaces, posing high requirements for production safety and equipment maintenance.

[0003] Traditional post-processing of sodium metasilicate crystals has long relied on manual operation for crushing and storage: workers first use tools such as impact drills to break up the solidified lumps of material one by one, reducing them to a size that can be collected with shovels; then, a specialized crusher further pulverizes them into fine particles, which are finally packaged and stored. This process has several significant drawbacks: First, during manual crushing and breaking, large amounts of sodium metasilicate dust are released into the air, severely polluting the working environment and causing chemical burns when the dust comes into contact with the skin and respiratory tract, directly threatening the health of operators; second, manual operation requires full participation in crushing, cleaning tools, and material handling, resulting in extremely high labor intensity, especially in high-temperature environments in summer, where heavy protective gear is required to prevent corrosion burns, leading to heatstroke or excessive fatigue and posing safety hazards; third, the high-temperature viscosity of sodium metasilicate makes it prone to adhering to the surfaces of impact drill bits, shovel blades, crusher cutters, and other tools, making cleaning extremely difficult, often causing tool adhesion failure or equipment jamming and shutdown, seriously affecting production continuity, reducing production efficiency, and making it difficult to meet the needs of large-scale production.

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] like Figure 1 , 2 As shown, a fully automatic walking crushing device is characterized by comprising:

[0036] Material receiving mechanism 1, used to receive materials;

[0037] The walking drive mechanism 2 is installed above the material receiving mechanism 1 and reciprocates along the extension direction of the material receiving mechanism 1;

[0038] The crushing actuator 3 is mounted on the walking drive mechanism 2 and includes a crushing roller body 31 and a material shovel 32 disposed on the surface of the crushing roller body 31. The crushing roller body 31 is connected to the roller body driver 33.

[0039] The control mechanism is electrically connected to the walking drive mechanism 2 and the roller driver 33, and is used to control the movement of the walking drive mechanism 2 and the crushing action of the crushing actuator 3.

[0040] Specifically, the material receiving mechanism 1 serves as the basic supporting structure, with the walking drive mechanism 2 mounted on top of it, capable of reciprocating along the extension direction of the material receiving mechanism 1. The crushing execution mechanism 3 is mounted on the walking drive mechanism 2, wherein the crushing roller 31 is connected to the roller driver 33, and the material shovel 32 is disposed on the surface of the crushing roller 31. The control mechanism is electrically connected to both the walking drive mechanism 2 and the roller driver 33. When the equipment is started, the control mechanism controls the walking drive mechanism 2 to reciprocate along the extension direction of the material receiving mechanism 1, while simultaneously controlling the roller driver 33 to drive the crushing roller 31 to rotate, thereby distributing and stirring the sodium metasilicate material in the material receiving mechanism 1, which is in the initial stage of liquid solidification (semi-fluid state), directly crushing it into granules, achieving "simultaneous solidification and crushing". Throughout the process, the walking and crushing actions are carried out in coordination, achieving comprehensive crushing treatment of the material. In this application, by setting up a walking drive mechanism 2 to drive the equipment to move back and forth along the material receiving mechanism 1, and the crushing execution mechanism 3 to rotate and crush synchronously, the step-by-step operation of first completely solidifying and then manually crushing in the traditional process is avoided. The operation time is shortened from the original 24-36 hours to within 8 hours, which greatly shortens the production time. By setting up a control mechanism to coordinate the movement of the walking drive mechanism 2 and the crushing action of the crushing execution mechanism 3, fully automatic operation is achieved without manual intervention, reducing manual operation and labor intensity. At the same time, it reduces the direct contact between operators and sodium metasilicate materials, reducing the harm of dust to the human body.

[0041] like Figure 1 , 3 As shown, the walking drive mechanism 2 includes:

[0042] The walking support 21 is a frame structure;

[0043] The walking transmission assembly 22 includes a rack 221 fixed on the material receiving mechanism 1 and a gear 222 mounted on the walking bracket 21, wherein the gear 222 meshes with the rack 221;

[0044] The walking drive motor 23 is connected to the gear 222 and is used to drive the walking bracket 21 to move back and forth along the rack 221.

[0045] Specifically, the frame structure of the walking support 21 provides solid and stable support for the entire mechanism, ensuring the stability of the structure during movement. The walking transmission component 22 uses a rack 221 and a gear 222 meshing together, which, together with the walking drive motor 23, drives the walking support 21 to move back and forth along the rack 221. This ensures that the walking drive mechanism 2 drives the crushing execution mechanism 3 to move smoothly along the extension direction of the material receiving mechanism 1 according to a preset trajectory, improving the uniformity and thoroughness of crushing. Moreover, compared with manual movement or other transmission methods, it effectively improves the automation level and reliability of equipment operation, further ensuring production efficiency.

[0046] like Figure 3 As shown, there are two gears 222 and two racks 221; the two racks 221 are fixedly arranged along both sides of the material receiving mechanism 1, and the two gears 222 are connected by a transmission rod 223, which is rotatably mounted on the walking bracket 21; the walking drive motor 23 is connected to the transmission rod 223 through a reducer, and is used to drive the transmission rod 223 to rotate around its central axis.

[0047] Specifically, the meshing of the racks 221 and gears 222 on both sides allows the walking support 21 to be subjected to more balanced forces, avoiding tilting or offset caused by unilateral forces and ensuring a smoother walking process. The transmission rod 223 synchronously connects the two gears 222, and with the power transmitted by the reducer, it can ensure that the two gears 222 rotate at the same speed, making the movement of the walking drive mechanism 2 along both sides of the material receiving mechanism 1 more synchronized, and further improving the accuracy of the walking trajectory. In addition, the reducer can effectively adjust the output speed and torque of the walking drive motor 23, enhancing the stability and reliability of the equipment operation.

[0048] like Figure 1 , 3 As shown, the walking support 21 has two walking wheels 211 on each side of its bottom, and the material receiving mechanism 1 has support rails 212 on both sides, with the walking wheels 211 placed in the support rails 212.

[0049] Specifically, the cooperation between the traveling wheel 211 and the support rail 212 can provide more stable support and guidance for the traveling bracket 21, further restrict the traveling trajectory, and make the movement of the traveling drive mechanism 2 more stable and reliable. At the same time, this structure can distribute the weight of the traveling bracket 21 and the components above it, reduce the stress load on the gear rack, reduce component wear, and extend the service life of the equipment.

[0050] like Figure 1 , 3 As shown, the walking drive mechanism 2 is also provided with a pushing and collecting mechanism 4. The pushing and collecting mechanism 4 includes a material shovel 41. Pushing arms 42 are provided on both sides of the material shovel 41. The two pushing arms 42 are rotatably installed at both ends of the crushing roller body 31. The material shovel 41 is hinged to the material shovel lifting driver 43. The material shovel lifting driver 43 is fixedly installed on the walking bracket 21.

[0051] Specifically, when there is no need to push materials, the material shovel lifting driver 43 drives the material shovel 41 to lift up, avoiding interference with the uncrushed materials and ensuring the continuity of the crushing operation; when pushing is required, the material shovel lifting driver 43 drives the material shovel 41 to descend, and the pushing arm 42 adjusts the angle through a rotatable connection, so that the material shovel 41 fits against the lower surface of the material receiving mechanism 1. In conjunction with the movement of the walking drive mechanism 2, the granular materials are efficiently pushed to the end of the material receiving mechanism 1, realizing full automation of the crushing and material collection process.

[0052] like Figure 2 As shown, the surface of the crushing roller body 31 has a plurality of screw holes evenly distributed along the axial direction; the material shovel 32 is detachably mounted on the crushing roller body 31 through the screw holes, and the height of the material shovel 32 can be adjusted by adjusting the depth of the material shovel 32 placed in the screw holes.

[0053] Specifically, the detachable installation facilitates the replacement and maintenance of the material-dispensing shovel 32. When the material-dispensing shovel 32 is worn or damaged, a new material-dispensing shovel 32 can be quickly replaced, avoiding the impact of a single component failure on the overall equipment operation. The height-adjustable design can flexibly adapt to sodium metasilicate materials in different states. Based on the viscosity and solidification degree of sodium metasilicate at different cooling stages, the height of the material-dispensing shovel 32 can be adjusted to achieve the best crushing effect. This ensures thorough crushing while reducing excessive contact between the material-dispensing shovel 32 and the material, further improving the applicability and crushing efficiency of the equipment.

[0054] like Figure 2 As shown, the roller drive 33 is a geared motor, the output end of the roller drive 33 is provided with a drive sprocket 34, the crushing roller 31 is provided with a driven sprocket 35, and the drive sprocket 34 and the driven sprocket 35 are connected by chain drive.

[0055] Specifically, the geared motor can provide a stable and suitable speed and torque for the crushing roller 31, ensuring that the material shovel 32 crushes materials efficiently; while the transmission method of the sprocket and chain can ensure that the power of the driving sprocket 34 is stably transmitted to the driven sprocket 35, so that the crushing roller 31 can operate continuously and stably, improving the crushing efficiency and operational reliability of the equipment.

[0056] like Figure 1 As shown, the material receiving mechanism 1 is a tank made of welded metal plates, and the bottom of the tank is provided with a ventilation gap; a detachable baffle is movably provided on the side of the material receiving mechanism 1.

[0057] Specifically, the welded metal plate tank structure is robust and can withstand the corrosiveness of sodium metasilicate, while providing a stable space for the material. The ventilation gap at the bottom promotes air circulation, which helps the material dissipate heat and cool down better in the tank, accelerating the condensation process and adapting to the characteristic of sodium metasilicate requiring cooling and condensation. The movable and detachable baffles on the sides are easy to disassemble quickly after the material is crushed for collection and bagging, improving the material collection efficiency.

[0058] like Figure 1 As shown, a support frame 5 is provided at the bottom of the material receiving mechanism 1.

[0059] Specifically, the support frame 5 provides stable support for the entire material receiving mechanism 1. The support frame 5 raises the tank a certain height off the ground, which not only better works in conjunction with the bottom ventilation gap, but also promotes air circulation at the bottom of the tank and enhances the heat dissipation and cooling effect.

[0060] The working principle of this device is as follows:

[0061] 1. Manually inject the physically cooled liquid sodium metasilicate into the material receiving mechanism 1; press the start button of the control mechanism, the equipment enters the fully automatic operation mode, the control mechanism initializes and sets parameters such as crushing time and walking speed;

[0062] 2. The walking drive motor 23 starts and drives the gear 222 of the walking transmission assembly 22 to rotate through the reducer, which drives the walking bracket 21 to move back and forth along the rack 221; the four walking wheels 211 at the bottom of the walking bracket 21 rotate synchronously in the support rails 212 on both sides of the material receiving mechanism 1 to ensure smooth movement.

[0063] 3. During the movement of the traveling support 21, the roller drive 33 reduction motor drives the driven sprocket 35 of the crushing roller 31 to rotate through the active sprocket 34 and chain; the crushing roller 31 drives the material shovel 32 to rotate, which pushes and stirs the sodium metasilicate material in the tank in the early stage of liquid solidification (semi-fluid state), and directly crushes it into granules, realizing "crushing while solidifying";

[0064] 4. When the crushing state is reached, the crushing roller 31 of the crushing actuator 3 stops rotating; the material shovel lifting driver 43 starts, pushing the material shovel 41 down to the bottom of the trough, and the crushed granular material is pushed to the movable baffle at the end of the material receiving mechanism 1 as the traveling bracket 21 moves forward; the granular material naturally slides down to the packaging bag or collection device below, completing the material collection.

[0065] 5. After the material collection is completed, the walking support 21 stops moving, the material shovel 41 is lifted and reset by the cylinder, and the equipment enters the standby state. No manual intervention is required throughout the process.

[0066] This fully automatic walking crushing equipment is equipped with a separate control system, offering both manual and automatic control modes. In manual mode, operators can perform precise and personalized control, independently adjusting the walking speed and direction of the walking drive mechanism 2 to flexibly adjust the movement rhythm and path according to the actual material crushing situation. They can also independently control the rotation speed and direction of the crushing roller 31 to adapt to the crushing requirements of materials in different states. Simultaneously, manual mode allows the equipment to move only via the walking drive mechanism 2 without rotating the crushing roller 31, facilitating equipment position adjustments when not performing crushing operations. It also allows for the rotation of the crushing roller 31 without the walking drive mechanism 2, focusing on crushing materials in a specific area. The manual control mode can specifically address various unexpected events that occur during operation. For example, when abnormal material accumulation occurs, it can be handled by independently adjusting the walking action of the walking drive mechanism 2 and the crushing action of the crushing actuator 3. When the equipment requires maintenance, it also allows for convenient control of individual components to operate or stop, facilitating maintenance work.

[0067] When in automatic mode, the equipment automatically enters the working state according to the preset program: the walking drive mechanism 2 automatically completes the back-and-forth movement within the material receiving mechanism 1, while simultaneously driving the crushing roller 31 to rotate for crushing operations. After crushing is completed, it automatically switches to the material collection mode, pushing the crushed material out through the material collection mechanism 4, without any manual intervention throughout the process. The automatic control mode, combined with the coordinated work of the equipment's walking drive mechanism 2, crushing execution mechanism 3, and material collection mechanism 4, completely changes the traditional high-intensity manual crushing operation mode, reducing human contact with corrosive materials, lowering safety hazards, while ensuring the continuity and stability of the production process, significantly improving production efficiency, and is especially suitable for large-scale production needs.

[0068] This application discloses a fully automatic walking crushing device. During operation, the control mechanism controls the walking drive mechanism 2 to reciprocate along the extension direction of the material receiving mechanism 1, while simultaneously controlling the roller driver 33 to drive the crushing roller 31. This process stirs and agitates the sodium metasilicate material in the material receiving mechanism 1, which is in the initial stage of liquid solidification (semi-fluid state), directly crushing it into granules. This achieves "simultaneous solidification and crushing," with the walking and crushing actions coordinated throughout the process for comprehensive material crushing. In this application, by setting the walking drive mechanism 2 to drive the device to move back and forth along the material receiving mechanism 1, and the crushing execution mechanism 3 to rotate synchronously for crushing, the step-by-step operation of first completely solidifying and then manually crushing in traditional processes is avoided. The operating time is shortened from the original 24-36 hours to within 8 hours, significantly reducing production time. By setting the control mechanism to uniformly coordinate the movement of the walking drive mechanism 2 and the crushing action of the crushing execution mechanism 3, fully automatic operation is achieved without manual intervention, reducing manual operation and labor intensity. Simultaneously, it reduces direct contact between operators and sodium metasilicate material, lowering the harm of dust to the human body.
