Description

Technical Field

[0001] The invention belongs to the technical field of mechanical devices, and in particular relates to a device and method for automatically separating, packaging and compressing a collected object-sand and soil mixture. Background Art

[0002] In today's era, with the development of the economy, industries such as tourism, agriculture, mining, and environmental protection have all experienced great development and earth-shaking changes. They all have their own requirements for more efficient, reliable, and more automated object collection technologies. This makes a method and device with superior performance that can be widely adapted to multiple application scenarios such as mining, agricultural product harvesting, and garbage cleaning, and can autonomously post-process the mixture of the collected objects and sandy soil particles a hot demand in the market. In the agricultural field, with the increasing demand for tuber agricultural products such as potatoes, the traditional manual sorting method has problems such as high labor intensity, low efficiency, and high cost, and automated separation and packaging technology can effectively solve these problems.

[0003] In the tourism industry, taking the collection technology required for beach cleaning as an example, it mainly relies on manual methods, which is not only labor-intensive but also has very poor working conditions. Cleaners need to bend down to pick up various garbage under the scorching sun or in bad weather. This repetitive and high-intensity labor poses a threat to their physical health. In addition, the manual cleaning method is inefficient and often takes a lot of time and manpower, which not only increases operating costs but also makes it difficult to meet the growing demand for cleaning. At the same time, uncompressed garbage is prone to leakage during transportation, causing secondary pollution to the environment. In addition, with the surge in the number of tourists, the garbage problem on the beach is becoming increasingly serious. The existing processing technology is highly dependent on people's own garbage classification awareness and garbage treatment base stations, which poses a severe challenge to the beauty of the environment and the balance of the ecology. In the field of mining, with the continuous advancement of automation technology, there are many types of collection technologies based on different mechanical configurations. The breakthrough of miniaturization and integration of post-processing modules will bring new breakthroughs to the economic benefits of the industry. In terms of environmental protection, traditional processing methods often cause secondary damage and pollution to the environment, while the integrated processing method of automatic, separation, and packaging can reduce the negative impact on the environment by optimizing the process and reducing human intervention.

[0004] Therefore, developing a device and method that can automatically and efficiently process the separation, packaging and compression of the collected material-sand mixture is of great significance for improving the overall efficiency of garbage disposal, reducing economic costs, protecting the natural environment and increasing the tourist attraction of the beach. The advent of this device and method will improve the automation level of material separation and processing in multiple industries, reduce the negative impact on the environment, and provide strong technical support for achieving sustainable development. Summary of the invention

[0005] The present invention provides a device and method for automatic separation, packaging and compression of a collection object-sand and soil mixture to solve the problems of the prior art: 1. Most of the prior art focuses on the development of one process in post-processing, and does not integrate multiple processes including separation, compression, and packaging, which is prone to adaptation problems between different processes. 2.

[0008] The separation module comprises a suction circular pipe structure (1) at the top of the device, an inclined vibrating screen (2) located below the suction circular pipe structure (1), and a smooth track (3) located below the inclined vibrating screen (2); when the collected material-sand mixture falls onto the inclined vibrating screen (2) through the suction circular pipe structure (1), the inclined vibrating screen (2) selectively filters impurities by high-frequency vibration, thereby achieving separation of the target collected material and fine impurities (12) in the sand; after the fine impurities (12) pass through the sieve holes of the inclined vibrating screen (2), they slide down from the device housing outlet (4) along the smooth track (3) to the outside of the device, thereby achieving the purpose of backfilling;

[0009] The packing module comprises a packing rod (5), a plastic bag storage box (6) and a pressure sensor. The pressure sensor is arranged at the bottom of the device. The packing rod (5) is arranged below the smooth track (3). The packing rod (5) comprises two slide rails (5-1) arranged side by side, a heating element (5-2) connected to the two slide rails (5-1) and a traction rod (5-3). A plastic bag (6-1) is installed in the plastic bag storage box (6). The traction rod (5-3) is connected to the plastic bag (6-1) and is used to traction the plastic bag (6-1) between the two slide rails (5 -1); when a larger collected object (13) slides down the inclined vibrating screen (2) to the plastic bag (6-1), the pressure sensor detects a change in the weight of the plastic bag (6-1), and sends a packing signal when the plastic bag (6-1) is fully filled. After the packing module receives the packing signal, the motor of the packing module drives two slide rails (5-1) located on both sides of the plastic bag (6-1) to move together, so that the opening of the plastic bag (6-1) is tightened due to squeezing, and then the opening of the plastic bag (6-1) is heat-sealed by the heating element (5-2);

[0010] The compression module comprises compressors (8) located on both sides of the unfolded plastic bag (6-1) and a magnetically controlled door (9) equipped with a varistor (9-1); the compressor (8) is responsible for compressing the plastic bag (6-1) filled with collected objects, and the magnetically controlled door (9) provides a channel for the block-shaped plastic bag (6-1) to be ejected after compression.

[0011] In an optional embodiment of the present invention, the packaging module further comprises a fan assembly (10), wherein the fan assembly (10) is arranged at the bottom of the device and is used to generate negative pressure so that the bottom of the plastic bag (6-1) is adsorbed to the bottom of the device, thereby achieving rapid unfolding of the plastic bag (6-1).

[0012] In an optional embodiment of the present invention, the fan assembly (10) includes four vacuum fans.

[0013] In an optional embodiment of the present invention, an auxiliary fan (7) is arranged on the bottom surface of the smooth track (3) in a direction toward the plastic bag (6-1), and the auxiliary fan (7) generates wind force to cause the plastic bag (6-1) to expand outwards.

[0014] In an optional embodiment of the present invention, a plurality of cameras (11) are arranged on the top and upper part of the device, and the cameras (11) are used for video recording and image recognition to carry out all-weather real-time monitoring of each functional module to ensure that each functional module performs the correct action at the correct time.

[0015] The embodiment of the present invention further provides a method for automatically separating, packaging and compressing a collection object-sand and soil mixture, which is implemented by a device for automatically separating, packaging and compressing a collection object-sand and soil mixture according to the above embodiment, and includes the following steps:

[0016] Step 1: After the collected material-sand mixture enters the device through the suction circular tube structure (1), it will directly fall onto the inclined vibrating screen (2); the inclined vibrating screen (2) allows the collected material to slide down while screening out fine impurities (12) in the sand; when the fine impurities (12) pass through the small holes of the inclined vibrating screen (2), they will quickly slide down along the smooth track (3) below to the outside of the device, thus achieving backfilling;

[0017] Step 2, the larger collected objects (13) slide along the inclined vibrating screen (2) into the plastic bag (6-1) of the packaging module, and the pressure sensor at the bottom of the device detects the change in the weight of the plastic bag (6-1). When the plastic bag (6-1) is full, it is closed and a packaging signal is sent. After the packaging module receives the packaging signal, the motor of the packaging module drives the two slide rails (5-1) located on both sides of the plastic bag (6-1) to move together, so that the opening of the plastic bag (6-1) is tightened due to squeezing, and then the opening of the plastic bag (6-1) is heat-sealed by the heating element (5-2), and the fused and sealed plastic bag (6-1) then enters the compression stage;

[0018] Step 3, the compressor (8) pushes the compression baffle plate through hydraulic pressure to compress the collected material in the plastic bag (6-1) to reduce its volume; a magnetic control door (9) with a piezoresistor (9-1) is provided on the other side of the hydraulic push rod; when the collected material in the plastic bag (6-1) is compressed to a certain extent and the pressure of the magnetic control door (9) exceeds the set threshold of the piezoresistor (9-1), the magnetic control door (9) automatically opens to allow the compressed plastic bag (6-1) to be pushed out of the device;

[0019] Step 4, when the plastic bag (6-1) is discharged from the device, the traction rod (5-3) takes out a new plastic bag from the plastic bag storage box (6), and fixes the bag opening to the two slide rails (5-1) of the packaging rod through the heating element (5-2); at the same time, the fan assembly (10) forms a negative pressure at the bottom of the device, so that the bottom of the plastic bag is tightly adsorbed to the bottom of the device, thereby realizing the rapid expansion of the plastic bag and collecting new collected objects.

[0020] Compared with the prior art, the embodiment of the present invention provides a device and method for automatically separating, packaging and compressing a collection object-sand mixture, which has the following beneficial effects:

[0021] (1) The present invention significantly improves the post-processing capacity of collected materials. It adopts a modular design concept to streamline the three main post-processing processes of separation, packaging and compression, and miniaturize the equipment required for the processes, thereby simplifying the processing process. At the same time, based on the modular design, the installation of the three modules can be adjusted according to the different operating environments and working conditions faced by the device, significantly improving the post-processing capacity of garbage, mineral particles and agricultural products in garbage disposal, mining and agricultural harvesting.

[0022] (2) The present invention has highly intelligent functions and is equipped with an all-weather image recognition system. It can accurately identify the situation inside the cylinder in a low-light, high-dynamic environment and feedback faults or other emergencies to the base station. It can also transmit information about whether the plastic bags are fully loaded and correctly placed through the deep learning system. The angle, frequency and vibration amplitude of the vibrating screen are adjusted through the negative feedback adjustment method to adapt to different bottom types and achieve the purpose of efficient operation.

[0023] (3) The present invention is more economical and ecologically friendly. The multi-integrated technology of the automatic processing process of the collected materials has greatly reduced the process flow and spread the operating costs. The intelligent self-monitoring and maintenance technology gets rid of the dependence on personnel and improves work efficiency. At the same time, the bottom particles can slide down the track after screening to achieve backfilling, which has better ecological affinity. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] The embodiment of the present invention provides a device for automatically separating, packaging and compressing a collection-sand mixture, including a separation module, a packaging module and a compression module. The device integrates the three functional modules of separation, compression and packaging of the collection-sand mixture through an integrated design concept, realizes a fully automated collection processing flow, greatly improves work efficiency, reduces labor costs, and reduces environmental pollution. The outer shell of the device is an upper and lower separated cylinder-shaped structure, and the upper and lower cylinders are independent of each other. The upper and lower cylinders can be combined by metal buckles, and the number of cylinders can be increased or decreased as needed to adapt to different working environments.

[0034] Specifically, Figure 1 and Figure 3 As shown, the separation module includes a suction circular tube structure 1 at the top of the device, an inclined vibrating screen 2 located below the suction circular tube structure 1, and a smooth track 3 located below the inclined vibrating screen 2; when the collected material-sand mixture falls onto the inclined vibrating screen 2 through the suction circular tube structure 1, the inclined vibrating screen 2 selectively filters impurities using high-frequency vibration to achieve separation of fine impurities 12 of the target collected material and sand, and then, after the fine impurities 12 pass through the sieve holes of the inclined vibrating screen 2, they slide along the smooth track 3 from the device housing outlet 4 to the outside of the device to achieve the purpose of backfilling.

[0035] In order to ensure that fine impurities such as sand and soil particles can pass through the sieve holes smoothly, this embodiment uses an electric control method to set a specific vibration screen inclination angle to ensure that the collected objects can slide smoothly, a reasonable screen hole size to selectively pass impurities, and a certain vibration frequency and amplitude to avoid power waste. At the same time, the vibration frequency and amplitude should be determined in conjunction with the inclination angle of the vibration screen and the roughness of the vibration screen surface, so that the fine impurities do not slide too fast and the vibration screen cannot play a role, affecting the screening efficiency. Compared with the traditional open-air independent vibration screen, this design not only improves the separation efficiency, but also extends the service life of the equipment. Furthermore, when the impurities pass through the small holes of the vibration screen, they will quickly slide down the smooth slope below to the outside of the barrel to achieve backfilling, while the larger-scale collected objects will slide along the vibration screen to the bottom of the upper barrel, and then enter the packaging module located in the lower barrel. In the above process, the separation of the target collection and impurities is complete, ensuring the high efficiency of subsequent processing.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the packing module is the core part of the device, which includes a packing rod 5, a plastic bag storage box 6 and a pressure sensor. The pressure sensor is arranged at the bottom of the device, and the packing rod 5 is arranged below the smooth track 3. The packing rod 5 includes two slide rails 5-1 arranged side by side, a heating element 5-2 connected to the two slide rails 5-1 and a traction rod 5-3. Plastic bags 6-1 are installed in the plastic bag storage box 6, that is, the plastic bag storage box is responsible for storing high-strength and high-ductility plastic bags to be used, so as to reduce the risk of plastic bags being punctured and leaking. The traction rod 5-3 is connected to the plastic bag 6-1, and is used to traction the plastic bag 6-1 to move on the two slide rails 5-1; when the larger-scale collected objects 13 slide along the inclined vibrating screen 2 to the plastic bag 6-1, the pressure sensor will detect the change in the weight of the plastic bag 6-1, and when the plastic bag 6-1 is fully filled, a packing signal is sent. After the packing module receives the packing signal, the motor of the packing module drives the two slide rails 5-1 located on both sides of the plastic bag 6-1 to close together, so that the opening of the plastic bag 6-1 is tightened due to squeezing, and then the opening of the plastic bag 6-1 is heat-sealed by the heating element 5-2. Heat-sealing technology is an advanced packaging method, which heats the plastic material to the melting point, and then quickly cools it to form a solid package. This method not only improves the strength of the package, but also ensures the sealing of the collected objects during subsequent compression and transportation, reducing pollution to the environment.

[0037] like Figure 1 and Figure 2As shown, the compression module includes a compressor 8 and a magnetic control door 9 equipped with a varistor 9-1 located on both sides of the plastic bag 6-1; the compressor 8 is responsible for compressing the plastic bag 6-1 full of collected objects, and the magnetic control door 9 provides a channel for the block plastic bag 6-1 to pop out after compression. Then, the magnetic control door 9 will automatically close, and the packaging module will continue to operate for the next round.

[0038] When the plastic bag is discharged from the drum, the baling rod will automatically start, take out a new plastic bag from the rolled plastic bag, and fix its bag mouth on the device. During this process, the fan assembly will start, and negative pressure will be formed through the four round holes at the bottom of the device, so that the bottom of the plastic bag is tightly adsorbed to the bottom of the device, and the plastic bag can be quickly unfolded. This automatic bagging design not only improves the accuracy of bagging, but also reduces manual operations and improves the safety of the entire system.

[0039] like Figure 1 and Figure 5 As shown, the packaging module also includes a fan assembly 10, which is arranged at the bottom of the device and is used to generate negative pressure so that the bottom of the plastic bag 6-1 is adsorbed to the lower part of the device to achieve rapid expansion of the plastic bag 6-1. The fan assembly 10 is composed of four fans, and the four fans are located directly below the two slide rails 5-1. An auxiliary fan 7 is arranged on the bottom surface of the smooth track 3 facing the direction of the plastic bag 6-1, and the auxiliary fan 7 generates wind force to expand the plastic bag 6-1 outward.

[0040] like Figure 1 and Figure 6As shown, multiple cameras 11 are arranged on the top and upper part of the device, and the cameras 11 are used for video recording and image recognition to carry out all-weather real-time monitoring of each functional module to ensure that each functional module performs the correct action at the right time. In this embodiment, an image recognition system is used to analyze the images and videos captured by the camera 11 in real time. The image recognition system is a set of algorithms that have been specially optimized to quickly identify and classify objects in the image to ensure that each device performs the correct action at the right time. For example, when the plastic bag is filled with collected objects and compressed, the camera will capture the expansion state of the plastic bag and pass this information to the image recognition system. The image recognition system then sends instructions to the packing rod to start the process of emptying and replacing the plastic bag. In addition, the image recognition system can also monitor other key components of the device, such as the state of the inclined vibrating screen, whether the slope is blocked, etc., to ensure the smooth operation of the entire device. If an abnormal situation is identified, the image recognition system will automatically alarm and stop the operation of related components when necessary to prevent damage to the device or accidents. The recognition function of the image recognition system also helps to improve the maintenance efficiency of the device. By analyzing historical image data, maintenance personnel can identify common failure modes and predict potential maintenance needs, thereby reducing unexpected downtime and improving the reliability and efficiency of the entire collection post-processing process. In short, the application of recognition technology of the camera and image recognition system has made the device for separation-packaging-compression of the collection-sand mixture of the present invention an important step in automation and intelligence. This innovative design not only improves the efficiency and accuracy of collection processing, but also enhances the self-monitoring and self-adjustment capabilities of the equipment, laying a solid foundation for realizing a truly intelligent collection post-processing system.

[0041] refer to Figure 7 The embodiment of the present invention further provides a method for automatically separating, packaging and compressing a collection object-sand and soil mixture, which is implemented by a device for automatically separating, packaging and compressing a collection object-sand and soil mixture according to the above embodiment, and includes the following steps:

[0042] Step 1: After the collected material-sand mixture enters the device through the suction circular tube structure 1, it will directly fall on the inclined vibrating screen 2; the inclined vibrating screen 2 allows the collected material to slide down while screening out the fine impurities 12 of the sand; when the fine impurities 12 pass through the small holes of the inclined vibrating screen 2, they will quickly slide down along the smooth track 3 below to the outside of the device to achieve backfilling;

[0043] Step 2, the larger collected objects 13 slide along the inclined vibrating screen 2 into the plastic bag 6-1 of the packaging module. The pressure sensor at the bottom of the device detects the weight change of the plastic bag 6-1, closes when the plastic bag 6-1 is full, and sends a packaging signal. After the packaging module receives the packaging signal, the motor of the packaging module drives the two slide rails 5-1 located on both sides of the plastic bag 6-1 to close together, so that the opening of the plastic bag 6-1 is tightened due to squeezing, and then the opening of the plastic bag 6-1 is heat-sealed by the heating element 5-2, and the fused and sealed plastic bag 6-1 then enters the compression stage;

[0044] Step 3, the compressor 8 compresses the collected material in the plastic bag 6-1 by hydraulically pushing the compression baffle to reduce its volume; a magnetic control door 9 with a piezoresistor 9-1 is provided on the other side of the hydraulic push rod; when the collected material in the plastic bag 6-1 is compressed to a certain extent and the pressure of the magnetic control door 9 exceeds the set threshold of the piezoresistor 9-1, the magnetic control door 9 automatically opens, allowing the compressed plastic bag 6-1 to be pushed out of the device;

[0045] Step 4, after the plastic bag 6-1 is discharged from the device, the traction rod 5-3 takes out a new plastic bag from the plastic bag storage box 6, and fixes its bag opening on the two slide rails 5-1 of the packaging rod through the heating element 5-2; at the same time, the fan assembly 10 forms a negative pressure at the bottom of the device, so that the bottom of the plastic bag is tightly adsorbed to the bottom of the device, thereby realizing the rapid expansion of the plastic bag and collecting new collection objects.

[0046] A device and method for automatic separation, packaging and compression of collected material-sand-soil mixture has the following innovations: Intensive all-weather intelligent operation technology: The device integrates three main post-processing processes and equipment of separation, packaging and compression in a limited volume cylinder, which significantly saves labor costs and process time costs, and facilitates centralized management. The image recognition system is embedded in a high-resolution camera and can work under high dynamic and low light conditions. It can identify multiple indicators of plastic bags including positioning, posture, and loading conditions to ensure that the device operates under all-weather conditions. The core is a set of advanced algorithms that can analyze the images captured by the camera in real time. After special optimization and iteration, it can quickly identify and classify objects in the image, ensure the accuracy and efficiency of the robot arm operation, and further improve the intelligence level of the entire device. Self-monitoring and maintenance technology: Through video recording and image recognition methods, key components are monitored in real time around the clock, such as the working status of the vibrating screen, whether the slope is blocked, and whether the conveyor belt is operating normally, to ensure the smooth operation of the entire device. If an abnormal situation is identified, the system will automatically alarm the base station in serious cases and immediately stop the operation of related components to prevent equipment damage or accidents; when it can be solved autonomously, it will adjust the angle and vibration frequency of the oblique vibrating screen to eliminate the risk. The image recognition function also helps to improve the maintenance efficiency of the device. By analyzing and accumulating historical image data and calculating the working status in real time, maintenance personnel can identify common faulty parts. Combined with adaptive modular processing technology, it is convenient for maintenance and replacement, thereby reducing downtime and improving the continuity and efficiency of the entire collection processing process.
