Description

Technical Field

[0001] This invention relates to material conveying technology, and more specifically to a material extraction method suitable for ton containers. Background Technology

[0002] Existing material extraction machines mainly consist of a material extraction pump and a material extraction pipe. During extraction, the operator inserts the material extraction pipe directly into the tonne container (which is composed of an inner container and a metal frame). The material extraction pump provides negative pressure to extract the liquid material from the container. During the extraction process, the operator typically uses a single extraction method of "one insertion, one extraction," meaning that after the material extraction pipe is inserted into the container, it is continuously pumped until it is difficult to extract any more material, at which point the material extraction pipe is pulled out. Because the opening of a tonne container is usually centered, when the suction pipe is inserted vertically from the opening, the suction end of the pipe can only reach the center area of ​​the bottom of the container, making it difficult to reach the bottom edge. Furthermore, since the bottom end of the suction pipe is usually flat, even if the operator adjusts the suction angle so that the pipe is angled to contact the bottom of the container, when the liquid level drops below the suction port, a gap will form between the flat suction end and the liquid level. This will cause air to be drawn in, interrupting the pumping process or causing cavitation, affecting the continuity of the pumping. The remaining material at the bottom of the container cannot be effectively suctioned, ultimately resulting in a large amount of residual material at the bottom.

[0003] The inability to completely remove residual material from the bottom of the container not only results in direct material waste and increased production costs, but also causes long-term contamination of the container's inner wall, necessitating manual cleaning and further increasing production costs and labor input. Furthermore, in chemical industry material extraction operations, operators need to directly contact and approach the packaging containers and materials, many of which are hazardous chemicals with strong odors, corrosive properties, or flammable and explosive characteristics. In a non-enclosed extraction environment, volatile gases can easily diffuse into the work environment, seriously affecting the health of operators and posing a risk of flash fires, explosions, and other major safety accidents.

[0004] In summary, there is an urgent need for a simple extraction method that can effectively remove residual material from the bottom corner of the ton container through a well-designed procedure. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a material extraction method that, through a reasonable step design, can effectively extract residual tailings from the bottom angle of a ton container.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a material extraction method suitable for ton containers, comprising the following steps: S1: The ton container filled with liquid is transferred to the preset material extraction station of the support frame, and the ton container is placed horizontally. S2: Open the lid of the ton container; S3: The suction mechanism descends into the ton container through the opening of the ton container and sucks up the material until the suction end of the suction mechanism contacts the bottom of the ton container to complete the first suction. S4: The suction mechanism is lifted upwards and separated from the opening of the ton container; S5: Tilt the ton container to one side, so that the ton container is tilted and raised, causing the liquid to flow to the angled bottom of the ton container; S6: Submerge the suction mechanism into the ton barrel again, so that the suction end of the suction mechanism moves to the bottom angle of the ton barrel, and suck up the tail material accumulated at the bottom angle of the ton barrel to complete the second suction. S7: The suction mechanism lifts the container upwards again and separates it from the opening of the ton container, restoring the ton container to a horizontal position and closing the lid of the ton container.

[0007] Compared with existing technologies, this invention has the following advantages: By dividing the material extraction process into two stages, namely the first extraction and the second extraction, and setting an intermediate step of "lifting the suction mechanism, tilting the ton, and then submerging again" between the two extractions, a two-stage material extraction strategy of "first extracting material horizontally from the ton, then tilting to extract the tail material" is formed. The first extraction is carried out in the horizontal state of the ton, and the suction end of the suction mechanism submerges to contact the bottom of the ton, which can quickly and efficiently extract the main material in the ton (continuously extracting until it is difficult to extract any more material). This stage has a large extraction volume and high efficiency. Then, the suction mechanism is lifted upward so that it avoids the interference position of the ton opening and the ton wall during the tilting process. The ton is then tilted to one side so that the residual tail material is concentrated and flows to the lowest angle of the bottom of the ton under the action of gravity. When the suction mechanism submerges for the second time, the suction end of the suction mechanism moves to the bottom angle of the ton and completely extracts the tail material accumulated there. Compared to the existing "single-time extraction" method, this invention uses a combination of two submersion and intermediate tilting steps. The first extraction is responsible for the efficient extraction of the main material, while the second extraction is specifically for the targeted removal of tailings at the bottom of the bucket. The two extraction steps perform their respective functions without interfering with each other, ensuring the extraction speed under normal working conditions and achieving thorough removal of residual material at the bottom of the bucket through the dedicated secondary extraction step. This method has good economic efficiency and practicality.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "fixing," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the corresponding meanings of the above terms in this invention according to the specific circumstances. Example 1

[0029] See Figure 1 , Figure 1The image shows a semi-automatic material extractor according to this embodiment, including a support frame 1, a column-type cantilever mechanism 2, a suction mechanism 3, and a controller 4. The support frame 1 is used to support the ton container 10. The column-type cantilever mechanism 2 is disposed on one side of the support frame 1. The suction mechanism 3 is installed on the cantilever 24 of the column-type cantilever mechanism 2. The controller 4 is connected to the support frame 1, the column-type cantilever mechanism 2, the suction mechanism 3, and other actuators via signal connections. Each actuator is electrically connected to the controller 4 via wires. The controller 4 can issue execution commands to each actuator according to the material extraction process to realize the automated operation of the semi-automatic material extractor.

[0030] The ton container 10 is composed of an inner container and a metal frame. The opening of the ton container 10 is centrally located and sealed with a lid. The ton container 10 contains liquids, such as chemicals, food ingredients, or chemical reagents. The operator uses a forklift to place the ton container 10 onto the support frame 1. The support frame 1's support position can be understood as the preset material extraction station of a semi-automatic material extraction machine. The support frame 1 allows the ton container 10 to be placed horizontally (e.g.,...). Figure 8 (as shown) and tilted lifting state (as shown) Figure 10 Convert between (as shown).

[0031] See Figure 2 The support frame 1 includes a fixed frame 11 and a tilting rotating frame 12. The fixed frame 11 and the tilting rotating frame 12 are connected by a rotating shaft 13. Both ends of the rotating shaft 13 are mounted with vertical bearings to ensure the smoothness and safety of the tilting rotating frame 12 when it rotates relative to the fixed frame 11. The ton container 10 is placed on the tilting rotating frame 12. A telescopic mechanism 14 is provided between the tilting rotating frame 12 and the column 21. The telescopic mechanism 14 and the rotating shaft 13 correspond to the left and right ends of the tilting rotating frame 12, respectively. The column 21 is provided with a support beam 22 for mounting the telescopic mechanism 14. There are two sets of telescopic mechanisms 14, arranged vertically. One end of each set of telescopic mechanisms 14 is hinged to the support beam 22, and the other end of the telescopic mechanism 14 is hinged to the tilting rotating frame 12. When the telescopic mechanism 14 retracts, the tilting rotating frame 12 unfolds relative to the fixed frame 11, and the ton container 10 tilts and rises. When the telescopic mechanism 14 extends, the tilting rotating frame 12 folds relative to the fixed frame 11, and the ton container 10 tilts and rises. The synchronous drive of the two telescopic mechanisms 14 improves the stability of the tilting rotating frame 12's balanced rotation relative to the fixed frame 11. The telescopic mechanism 14 can be any of a pneumatic cylinder, hydraulic cylinder, or electric actuator, as long as it can drive the tilting rotating frame 12 to rotate relative to the fixed frame 11. Through the telescopic movement of the telescopic mechanism 14, the tilting rotating frame 12 rotates relative to the fixed frame 11 around the rotation axis of the rotating shaft 13, thereby causing the ton container 10 to tilt and rise. The telescopic mechanism 14 is signal-connected to the controller 4, which controls its telescopic movement according to the operator's input commands.

[0032] The tilting rotating frame 12 is equipped with a first limiting baffle 15, which corresponds to the location of the rotating shaft 13. The first limiting baffle 15 can limit the displacement or tipping of the ton container 10 in the tilting direction during and while tilting. The tilting rotating frame 12 is also equipped with two second limiting baffles 16, which are perpendicular to the first limiting baffle 15 and located at the front and rear ends of the tilting rotating frame 12. The two second limiting baffles 16 can limit the position of the ton container 10 in the front-rear direction, and each of the two second limiting baffles 16 is provided with a clearance opening to allow forklift forklifts to operate. The enclosed area of ​​the two second limiting baffles 16 and the first limiting baffle 15 constitutes the preset material extraction station of the semi-automatic material extractor. A buffer pad 17 is provided on the mounting surface of the fixed frame 11 relative to the tilting rotating frame 12 to prevent the tilting rotating frame 12 from having a hard collision with the fixed frame 11 and causing irreversible damage.

[0033] See Figures 1 to 3 The column-type cantilever mechanism 2 includes a column 21, a rotating seat 23 mounted on the upper end of the column 21, and a cantilever 24 connected to the rotating seat 23. The column 21 is vertically arranged and located on the side of the support frame 1 to facilitate the installation of the telescopic mechanism 14. The rotating seat 23 and the column 21 are located on the same axis, and the axis of rotation of the rotating seat 23 is vertically arranged. The cantilever 24 is perpendicular to the column 21. One end of the cantilever 24 is connected to the rotating seat 23, and the other end of the cantilever 24 is provided with a first handle 25. When the operator applies force to the first handle 25, the cantilever 24 rotates around the axis of rotation of the rotating seat 23, and the cantilever 24 can rotate circumferentially relative to the rotating seat 23.

[0034] The cantilever 24 is provided with a first guide rail 26 and a sliding bracket 27. The first guide rail 26 is oriented perpendicular to the rotation axis of the rotating seat 23. A slider that cooperates with the first guide rail 26 is mounted on the sliding bracket 27, allowing the sliding bracket 27 to move along the first guide rail 26. A second handle 28 is provided on the sliding bracket 27, which is located along the length of the cantilever 24 and is situated at the rear of the cantilever 24. When the operator applies force to the second handle 28, the sliding bracket 27 moves left or right relative to the first guide rail 26. The suction mechanism 3 is fixedly connected to the sliding bracket 27 and is located at the front of the cantilever 24. The sliding bracket 27 moves along the first guide rail 26 to drive the suction mechanism 3 to move along the cantilever 24. By rotating the cantilever 24 relative to the column 21 in the circumferential direction and moving the sliding bracket 27 left and right along the first guide rail 26, the rotation area of ​​the cantilever 24 can cover the area where the ton barrel 10 is located, so as to realize the positioning of the suction mechanism 3 at any position in the horizontal plane above the ton barrel 10. The suction mechanism 3 can be flexibly moved to the top of the ton barrel opening under the drive of the cantilever 24, and moved out of the area where the ton barrel 10 is located after the material is sucked out.

[0035] An operation panel 29 for operating the semi-automatic material extractor is installed at the end of the cantilever 24. The operation panel 29 is positioned corresponding to the location of the two handles to facilitate operator control of the semi-automatic material extractor. The operation panel 29 has a display and various input / execution command buttons. The display shows the status of the semi-automatic material extractor, operation parameters, and icons that teach and demonstrate operating methods for the operator. The operator can perform various operations by touching the corresponding icons and operation buttons. The operation panel 29 is connected to the controller 4 via wires to control the semi-automatic material extractor, such as: the tilting rotation frame 12 relative to the fixed frame 11, the locking operation of the cantilever 24 relative to the column 21, the locking operation of the sliding bracket 27 relative to the cantilever 24, and the suction operation of the suction mechanism 3.

[0036] See Figure 1 and Figure 4 The suction mechanism 3 includes a linear drive module 31 arranged in the vertical direction, a suction pipe 32 slidably connected to the linear drive module 31, and a control valve 33 disposed on the suction pipe 32 and controlling the opening and closing of the coarse suction pipe 325. The linear drive module 31 is fixedly mounted on the sliding bracket 27 to ensure the secure installation of the linear drive module 31. The linear drive module 31 is driven by a servo motor 34 and signal-connected to the controller 4. The servo motor 34 is mainly used for high-precision, high-response-speed automated control. Of course, in other embodiments, the linear drive module 31 can also be replaced by a ball screw type linear module or a synchronous belt type linear module, etc.

[0037] A first sliding seat 311 is mounted on the linear drive module 31, which can slide up and down along the driving direction of the linear drive module 31. A second sliding seat 312 connected to the first sliding seat 311 is mounted on the extraction pipe 32. The second sliding seat 312 is fixedly connected to the extraction pipe 32. The linear drive module 31 can control the rise and fall of the extraction pipe 32 relative to the ton container 10. When the suction port of the extraction pipe 32 extends into the ton container, extraction is performed, eliminating the need for manual insertion and removal of the extraction pipe and reducing the labor intensity of the operator. An upper limit sensor is provided on the upper part of the linear drive module 31 to limit the upward movement of the first sliding seat 311. The upper limit sensor is used to limit the maximum upward stroke of the first sliding seat 311 to prevent the extraction pipe 32 from moving excessively upward and leaving the working range. The lower part of the linear drive module 31 is equipped with a lower limit sensor to limit the downward movement of the first sliding seat 311. The lower limit sensor is used to limit the maximum downward stroke of the first sliding seat 311 to prevent the suction pipe 32 from excessively moving downward and puncturing the ton container 10 or causing damage to the suction mechanism 3. The installation positions of the upper and lower limit sensors can be calculated according to the size of the ton container. When the upper limit sensor is triggered, it indicates that the suction port of the suction pipe 32 is separated from the ton container opening and is in the initial position. When the lower limit sensor is triggered, it indicates that the suction port of the suction pipe 32 has reached the bottom of the ton container. Both the upper and lower limit sensors are connected to the controller 4 so that the controller 4 can issue a stop command to the servo motor 34.

[0038] See Figure 4 and Figure 5In this embodiment, to further enhance the automatic protection function of the semi-automatic material feeder, a third sliding seat 313 is provided between the first sliding seat 311 and the second sliding seat 312. The inner end face of the third sliding seat 313 corresponds to the linear drive module 31, and the outer end face of the third sliding seat 313 corresponds to the second sliding seat 312. The third sliding seat 313 is fixedly connected to the first sliding seat 311. The outer end face of the third sliding seat 313 is provided with a second guide rail 314, and the inner end face of the second sliding seat 312 is provided with a slider that slides along the second guide rail 314. The outer end face of the second sliding seat 312 is fixedly connected to the material feeding pipe 32. In its initial state, the extraction pipe 32 is at the bottom of the second guide rail 314 due to its own weight. When the extraction pipe 32 encounters resistance during its downward movement, it slides upward along the second guide rail 314. For example, when the extraction pipe 32 moves downward and contacts the bottom or wall of the ton container, it encounters resistance and slides upward along the second guide rail 314, preventing the extraction pipe 32 from puncturing the ton container 10 and improving the automatic protection function of the semi-automatic extraction machine. A photoelectric sensor is provided between the second sliding seat 312 and the third sliding seat 313. The photoelectric sensor is used to detect the sliding position of the second sliding seat 312 relative to the third sliding seat 313. When the photoelectric sensor is triggered, it sends a limit signal to the controller 4. The controller 4 issues a stop command to the servo motor 34, realizing the automated operation of the automatic protection.

[0039] See Figure 6 and Figure 7The material extraction pipeline 32 includes an extraction section 321, a first branch 322, a second branch 323, and an outlet section 324 arranged sequentially along the material conveying direction. The extraction section 321 is installed on the outer end face of the second sliding seat 312 by a fixing member to achieve a fixed connection between the entire material extraction pipeline 32 and the second sliding seat 312. The extraction section 321 includes a coarse extraction pipe 325 and a fine extraction pipe 326, both of which are slender round pipes and serve as the suction port of the suction pipeline, extending from the opening of the ton container 10 into the ton container. The linear drive module 31 drives the coarse extraction pipe 325 and the fine extraction pipe 326 to simultaneously extend into or retract from the ton container. The coarse suction pipe 325 and the fine suction pipe 326 are coaxially arranged. The fine suction pipe 326 extends downward and protrudes from the suction port end face of the coarse suction pipe 325. The coarse suction pipe 325 is sleeved around the fine suction pipe 326. There is a suction gap between the coarse suction pipe 325 and the fine suction pipe 326, which is suitable for the coarse suction pipe 325 to suck up materials. By setting the sleeve structure of the coarse suction pipe 325 sleeved around the fine suction pipe 326, a suction gap is formed between the coarse suction pipe 325 and the fine suction pipe 326. On the one hand, the fine suction pipe 326 is effectively protected inside the coarse suction pipe 325, avoiding damage to the fine suction pipe 326 due to collision during insertion and withdrawal. On the other hand, the coarse suction pipe 325 and the fine suction pipe 326 each form an independent suction channel. When the ton container 10 is in a horizontal position, they can work simultaneously to increase the suction flow rate. The ratio of the outer diameter of the coarse suction pipe 325 to the outer diameter of the fine suction pipe 326 is 5:2. The suction port of the coarse suction pipe 325 has a flat opening, while the suction port of the fine suction pipe 326 has an angled opening, in order to optimize the material suction channel. Preferably, both the coarse suction pipe 325 and the fine suction pipe 326 are made of stainless steel, which has good corrosion resistance and is suitable for suction operations of corrosive materials in the chemical industry.

[0040] The outlet end of the coarse extraction pipe 325 is connected to the inlet end of the first branch 322, and the outlet end of the fine extraction pipe 326 is connected to the inlet end of the second branch 323. A portion of the first branch 322 and the second branch 323 are arranged in parallel. After the outlet ends of the first branch 322 and the second branch 323 merge, they are connected to the inlet end of the discharge section 324. The discharge section 324 has a discharge end at its end, which connects to the discharge pipeline (not shown in the figure). The discharge pipeline is connected to an externally installed material pump and is equipped with a pneumatic ball valve for controlling the air path. The material pump can be used with a semi-automatic material pump, or the discharge pipeline can be connected to a pre-installed vacuum pumping system in the production workshop. The material pump can be a diaphragm pump or other negative pressure pump, as long as it can provide sufficient negative pressure to extract the material from the ton container 10. Control valve 33 is located on the first branch 322 to control the opening and closing of the coarse drawing pipe 325. Control valve 33 is a pneumatic quick-release angle seat valve. In other embodiments, control valve 33 can be a solenoid valve or an electric valve, etc., depending on the actual application scenario.

[0041] When the ton container 10 is in a horizontal position, the pneumatic ball valve and control valve 33 are opened simultaneously, and the coarse suction pipe 325 and fine suction pipe 326 simultaneously suck up the material. When the ton container 10 is in an inclined and raised position, only the pneumatic ball valve needs to be opened and the control valve 33 needs to be closed. Only the fine suction pipe 326 sucks up the tail material remaining at the bottom angle of the ton container. Both the pneumatic ball valve and the control valve 33 are connected to the controller 4 and execute the control commands issued by the controller 4. The two material extraction methods are easy to switch and simple to control.

[0042] In this embodiment, the linear drive module 31 is driven by the servo motor 34 to control the rise and fall of the suction pipe 32. The rotation frequency of the servo motor 34 is matched with the operating frequency of the suction pump. For example, the drop height of the liquid level in the tank is calculated based on the amount of liquid pumped per second, and then the rotation speed of the servo motor 34, i.e. the descent speed of the first sliding seat 311, is controlled to ensure that the suction pipe 32 descends at a uniform speed, and its descent speed is basically consistent with the descent speed of the liquid level. This ensures that the descent position of the suction pipe 32 is basically flush with the liquid level and the suction port is always below the liquid level. This ensures that the coarse suction pipe 325 and the fine suction pipe 326 simultaneously suck up materials, achieving efficient and high-flow suction of materials in the tank. It also avoids excessive liquid adhering to the pipe walls of the coarse suction pipe 325 and the fine suction pipe 326. Of course, in other embodiments, a weighing device can be installed on the support frame 1 to weigh the entire ton 10. When the weight of the liquid in the ton decreases, the rotation speed of the servo motor 34 is adjusted in real time according to the decrease in weight per second, which can also ensure that the pumping pipe 32 descends at a uniform speed, and its descent speed is basically consistent with the descent speed of the liquid surface.

[0043] See Figure 1 and Figure 5The column 21 is set vertically, the cantilever 24 is set horizontally, the support frame 1 is located below the cantilever 24, the rotating shaft 13 is set away from the column 21 relative to the telescopic mechanism 14, the linear drive module 31 is set at an angle β from top to bottom, the upper part of the linear drive module 31 tends to the left, the lower part of the linear drive module 31 tends to the right, and the linear drive module 31 is tilted from left to right. The suction port of the thin suction pipe 326 is beveled, and the bevel angle α and the tilt angle β are complementary angles (i.e., α+β=90 degrees). When the ton 10 is in a horizontal position, the thin suction pipe 326 moves downward along the tilt angle β to the bottom of the ton 10, and the end face of the beveled port of the thin suction pipe 326 is parallel to the plane of the bottom surface of the ton 10 and approaches the bottom of the ton 10 (it is not tightly attached and still leaves a gap), so that the thin suction pipe 326 can cooperate with the coarse suction pipe 325 to quickly suck up materials. When the ton 10 is in a tilted and raised position, the thin suction pipe 326 moves downward along the tilt angle β to the bottom corner of the ton 10, and the beveled port of the thin suction pipe 326 is close to the arc part of the bottom corner of the ton 10 (it is not tightly attached and still leaves a gap). The oblique cutting angle α, the tilt angle β, and the rotation angle of the tilting rotating frame 12 relative to the fixed frame 11 can be calculated by combining the opening size and coordinate position of the barrel mouth. When the ton barrel 10 is in a tilted and raised state, the thin suction pipe 326 can accurately extend through the barrel mouth to the oblique angle at the bottom of the ton barrel without contacting the barrel mouth or barrel wall. Compared with the prior art, which requires manual judgment of the position of residual material at the bottom of the barrel and manual adjustment of the suction pipe angle, this application uses the tilting and raising of the tilting rotating frame 12 to automatically concentrate the tail material to the oblique angle at the bottom of the barrel. Combined with the fixed-point suction of the thin suction pipe 326, the entire material extraction process does not require manual intervention or judgment, reducing the dependence of material extraction operations on the experience and skills of operators. The operation is simple, the material extraction effect is stable and reliable, and it has good prospects for promotion and application.

[0044] The second guide rail 314 on the outer end face of the third sliding seat 313 is perpendicular to the cantilever 24. Since the cantilever 24 is basically parallel to the ground, it can also be understood that the second guide rail 314 is perpendicular to the ground. The setting angle and tilt angle β of the second guide rail 314 are alternately set. When the material extraction pipe 32 encounters resistance during downward movement, the vertically set second guide rail 314 is suitable for improving the smoothness of the upward sliding of the material extraction pipe 32 relative to the second guide rail 314, and will not cause jamming.

[0045] See Figure 4The suction mechanism 3 also includes an exhaust pipe 35 installed at the bottom of the linear drive module 31. When the suction pipe 32 extends into the ton container to suction materials, the suction end of the exhaust pipe 35 is close to the opening of the ton container 10. When the lid of the ton container 10 is opened, the liquid inside the ton container will diffuse exhaust gas out of the container through the opening. The suction end of the exhaust pipe 35 is close to the opening to ensure that volatile gases escaping from the opening are promptly suctioned during the material suction process. The exhaust pipe 35 is connected to the suction system installed in the production workshop via a flexible hose, the length of which is sufficient to accommodate the movement range of the cantilever 24. Suctioning exhaust gas through the exhaust pipe 35 prevents gas pollution of the working environment.

[0046] See Figure 4 The suction mechanism 3 also includes a drip tray 36 installed at the bottom of the linear drive module 31. When the suction pipe 32 stops pumping, the drip tray 36 is moved by a cylinder to directly below the suction port of the suction pipe 32 to collect liquid dripping from the walls of the coarse suction pipe 325 and the fine suction pipe 326, keeping the surface of the ton container 10 clean and preventing liquid contamination of the environment. When the suction pipe 32 needs to submerge again, the cylinder moves the drip tray 36 away to avoid interfering with the movement of the suction pipe 32. This cylinder is signal-connected to the controller 4. In other embodiments, the drip tray 36 at the bottom of the linear drive module 31 may have a drain port at its bottom, which is connected to a waste liquid collection container via a pipe.

[0047] The following is in conjunction with the appendix Figures 1 to 11 ,as well as Figure 28 Detailed explanation of the working process of the semi-automatic material feeder in this invention: Step S1: Transfer the ton container to the preset material extraction station. In the initial state, the operator uses a forklift to place the ton 10 to be extracted on the preset extraction position of the tilting rotating frame 12, at which time the ton 10 is in a horizontal position.

[0048] Step S2: Open the lid of the tonne container. The operator applies force to the bucket lid and opens it manually or with a tool.

[0049] Step S3: First material intake The operator applies force to the first handle 25 and the second handle 28 to move the suction port of the suction pipe 32 directly above the opening of the ton container 10 (e.g., Figure 8(As shown). The operator starts the linear drive module 31 via the control panel 29. The first sliding seat 311 drives the second sliding seat 312 and the suction pipe 32 to slide downwards synchronously. The suction section 321 of the suction pipe 32 moves into the ton container through the opening at an inclination angle β. The suction port of the suction pipe 32 extends into the opening and submerges below the liquid surface. The suction pump is started and the pneumatic ball valve and control valve 33 are opened. The suction ports of the coarse suction pipe 325 and the fine suction pipe 326 simultaneously suck up the material. During the suction process, the linear drive module 31 controls the suction pipe 32 to descend at a uniform speed according to the suction rate of the suction pump, so that the suction end of the suction pipe 32 is always kept at an appropriate position below the liquid surface. The coarse suction pipe 325 and the fine suction pipe 326 descend at a uniform speed as the liquid decreases and simultaneously suck up the liquid. When the suction port of the suction pipe 32 reaches the bottom of the ton container (e.g. Figure 9 As shown in the diagram, the lower limit sensor is triggered, and the controller 4 sends a command to the servo motor 34 to stop rotating. At this time, most of the material in the ton container has been extracted, with only a small amount of tailings remaining at the bottom, thus completing the first suction. It should be noted that at this point, the suction port of the coarse suction pipe 325 is basically flush with the liquid surface. When the liquid level in the container drops below the suction port of the coarse suction pipe 325, and only a small amount of tailings remain at the bottom, suction needs to be stopped to ensure that the coarse suction pipe 325 does not suck in a large amount of air.

[0050] Step S4: Lift the suction mechanism upwards. After the first extraction is completed, the controller 4 controls the servo motor 34 to reverse, and the linear drive module 31 drives the extraction pipe 32 to move upward. The coarse extraction pipe and the fine extraction pipe exit the ton barrel simultaneously. The upward speed of the extraction pipe 32 can be greater than its downward speed. When the first sliding seat 311 moves upward and triggers the upper limit sensor, the linear drive module 31 stops driving upward, and the suction mechanism 3 separates from the barrel opening of the ton barrel 10.

[0051] Step S5: Tilt the container to one side The operator controls the telescopic mechanism 14 via the control panel 29, driving the tilting rotating frame 12 to rotate relative to the fixed frame 11 around the rotation axis of the rotating shaft 13. When the tilting rotating frame 12 rotates to the preset tilt angle, the telescopic mechanism 14 is controlled to stop, causing the ton 10 to tilt to one side. At this time, the ton 10 is in a tilted and raised state, and the liquid material remaining at the bottom of the ton flows to the tilted corner at the bottom of the ton under the action of gravity.

[0052] Step S6: Second feeding After the ton container 10 is tilted to the preset tilt angle, the position of the container opening relative to the suction port of the suction pipe 32 changes. The operator needs to apply force again to the first handle 25 and the second handle 28, and move the suction port of the suction pipe 32 back to directly above the opening of the ton container 10 (e.g., ...). Figure 10(As shown). The operator then restarts the linear drive module 31 via the control panel 29. The first sliding seat 311 drives the second sliding seat 312 and the suction pipe 32 to slide downwards simultaneously. The suction section 321 of the suction pipe 32 extends into the barrel opening at an inclination angle β and moves towards the angled bottom of the barrel. When the suction port of the thin suction pipe 326 abuts against the angled bottom of the barrel (the junction of the barrel wall and the bottom), the resistance at the angled bottom causes the suction pipe 32 to slide upwards along the second guide rail 314, preventing it from puncturing the bottom of the barrel. The upward-moving suction pipe 32 causes the second sliding seat 312 to move upwards relative to the third sliding seat 313, triggering the photoelectric sensor and sending a feedback signal to control the servo motor 34 to stop rotating. The suction pipe 32 no longer descends and maintains its current position in contact with the angled bottom of the barrel. At this time, the angled end of the thin suction pipe 326 is close to the curved part of the angled bottom of the barrel (e.g., Figure 11 (As shown). Start the material pump and open the pneumatic ball valve, and close the control valve 33 (the coarse suction pipe 325 stops suction). Only the tail material remaining at the bottom angle of the ton container is sucked through the fine suction pipe 326 until the tail material is completely sucked out, thus completing the second suction.

[0053] Step S7: The suction mechanism lifts upwards again, the ton container returns to its original position, and the lid is closed. After the second material suction is completed, the material pump and pneumatic ball valve are turned off, and the servo motor 34 is reversed again. The linear drive module 31 drives the material suction pipe 32 to move upward again, and the coarse and fine suction pipes simultaneously exit the ton container until the upper limit sensor on the upper part of the linear drive module 31 is triggered, the servo motor 34 stops rotating, and the suction mechanism 3 separates from the opening of the ton container 10 and returns to its initial position. The operator controls the telescopic mechanism 14 to reverse its movement again through the control panel 29, driving the tilting rotating frame 122 to rotate in the opposite direction relative to the fixed frame 11 around the rotation axis of the rotating shaft 13, so that the ton container 10 returns from the tilted and raised state to the horizontal position. The operator manually closes the lid or closes the lid with a tool, and the operator uses a forklift to remove the empty ton container 10 from the support frame 1. This completes one material suction cycle.

[0054] It should be noted that: the suction end of the exhaust pipe 35 is close to the barrel opening during the material extraction process and sucks up the volatile gases escaping from the barrel opening; after the second material extraction is completed, the receiving trough 36 is driven by the cylinder to move below the suction end of the extraction pipe 32 to receive the liquid dripping from the pipe walls of the coarse extraction pipe 325 and the fine extraction pipe 326. Example 2

[0055] See Figure 12 and Figure 13The difference between this embodiment and Embodiment 1 is that the material extraction equipment is a fully automatic material extraction machine, but the material extraction steps remain the same. This fully automatic material extraction machine includes a frame 5, a support frame 6, a roller conveyor 67, an XY positioning and translation mechanism 7, a capping mechanism 8, a suction mechanism 9, and a controller 4. The support frame 6 is located inside the frame 5 and is used to support the ton container 10. The XY positioning and translation mechanism 7 is located above the support frame 6. The capping mechanism 8 and the suction mechanism 9 are mounted on the XY positioning and translation mechanism 7, which is adapted to drive the capping mechanism 8 and the suction mechanism 9 to move relative to the ton container 10. The roller conveyor 67 is located outside the frame 5 and connected to the frame 5. The roller conveyor 67 can transport the ton container 10 onto the support frame 6. The controller 4 is located outside the frame 5. The controller 4 is connected to the support frame 6, roller conveyor 67, XY positioning and translation mechanism 7, capping mechanism 8, and suction mechanism 9, among other actuators. Each actuator is electrically connected to the controller 4 via wires. The controller 4 sequentially issues execution commands to each actuator according to a preset material extraction process to achieve automated operation of the fully automatic material extractor. The controller 4 can be a programmable logic controller or an industrial computer, and it stores a preset material extraction process program internally.

[0056] The front side of the frame 5 is also equipped with an operation panel 29 for operating the fully automatic material feeder. The description of the operation panel 29 can be found in the description of the operation panel in Embodiment 1, and will not be repeated here. In this embodiment, the operation panel 29 can control the fully automatic material feeder, for example: the conveying operation of the roller conveyor 67, the flipping operation of the tilting rotating frame 62 relative to the fixed frame 61, the movement and positioning operation of the XY positioning and translation mechanism 7 in the XY plane, the capping operation of the capping mechanism 8, and the suction operation of the suction mechanism 9, etc.

[0057] Operators use a forklift or an overhead crane installed in the workshop to place the ton container 10 onto the roller conveyor 67. The roller conveyor 67 is located on the right side of the frame 5 and connected to the ton container inlet on the frame 5, used to transport the ton container 10 to a preset extraction station on the support frame 6. The ton container 10 enters the preset extraction station from the right side of the frame 5. After the extraction operation is completed, it returns to the roller conveyor 67, whereby operators use a forklift or an overhead crane installed in the workshop to remove the ton container 10 from the roller conveyor 67. The roller conveyor 67 is driven by a geared motor, which is connected to the controller 4 and automatically starts and stops according to the preset extraction process of the fully automatic extraction machine.

[0058] See Figures 14 to 17The support frame 6 includes a fixed frame 61 and an inclined rotating frame 62, which are connected by a rotating shaft 63. The ton drum 10 is placed on the inclined rotating frame 62. The inclined rotating frame 62 is provided with a limiting component 25 for restricting the movement of the ton drum 10 relative to the inclined rotating frame 62, and a roller conveyor mechanism 64 suitable for conveying the ton drum 10. The roller conveyor mechanism 64 is driven by another geared motor and is signal-connected to the controller 4. The inclined rotating frame 62 is suitable for receiving the ton drum 10 conveyed by the roller conveyor 67, ensuring that the ton drum 10 smoothly transitions from the roller conveyor 67 to the inclined rotating frame 62 and moves to the preset extraction position of the ton drum 10. The inclined rotating frame 62 is provided with a photoelectric displacement sensor. When the ton drum 10 moves to the preset extraction position, the photoelectric displacement sensor is triggered and sends a signal to the controller 4. The controller 4 sends an execution command to the aforementioned geared motor to stop rotation.

[0059] By setting up a roller conveyor 67, the automatic conveying of the ton container 10 is realized. Only manual labor is required to transfer the ton container 10 to the roller conveyor 67 using a forklift or overhead crane, which can reduce labor costs and improve the continuous operation capability of the production line. At the same time, the support frame 6 is connected to the roller conveyor 67, and the ton container 10 is conveyed by the roller conveyor 67 to the preset material extraction position of the support frame 6. The conveying and extraction are seamlessly connected, and the material flow efficiency is high.

[0060] A telescopic mechanism 66 is provided between the tilting rotating frame 62 and the fixed frame 61. One end of the telescopic mechanism 66 is hinged to the fixed frame 61, and the other end is hinged to the tilting rotating frame 62. The telescopic mechanism 66's extension and retraction drives the tilting rotating frame 62 to rotate relative to the fixed frame 61 around the rotation axis of the rotating shaft 63. The tilting rotating frame 62 tilts and lifts relative to the fixed frame 61 around the rotation axis of the rotating shaft 63, thereby tilting and lifting the ton container 10 upwards. The rotating shaft 63 is located at the front of the tilting rotating frame 62, and the tilting rotating frame 62 flips relative to the fixed frame 61 from back to front. When the telescopic mechanism 66 extends, the tilting rotating frame 62 unfolds relative to the fixed frame 61, and the ton container 10 transitions to a tilted and lifted state; when the telescopic mechanism 66 retracts, the tilting rotating frame 62 folds relative to the fixed frame 61, and the ton container 10 transitions to a horizontal position. The telescopic mechanism 66 is signal-connected to the controller 4, which controls its extension and retraction according to a preset material extraction process.

[0061] The limiting assembly 25 includes a first cylinder limiter 651 and a second cylinder limiter 652 mounted on the tilting rotating frame 62. The first cylinder limiter 651 is located on the front side of the ton container 10, and the second cylinder limiter 652 is located on the rear side of the ton container 10. When the ton container 10 is conveyed to the preset material extraction station on the tilting rotating frame 62, the first cylinder limiter 651 and the second cylinder limiter 652 extend simultaneously to clamp and position the ton container 10 from both the front and rear sides. During and while the ton container 10 is tilting and lifting, the first cylinder limiter 651 and the second cylinder limiter 652 remain extended to prevent the ton container 10 from shifting laterally or tipping over during the tilting and lifting process. When the ton container 10 completes the material extraction operation and returns to a horizontal position, the restriction on the ton container 10 can be released. The first cylinder limiter 651 and the second cylinder limiter 652 are signal-connected to the controller 4.

[0062] See Figure 18 In this embodiment, the XY positioning and translation mechanism 7 is located inside the frame 5 and above the support frame 6. The XY positioning and translation mechanism 7 includes a Y-axis drive mechanism 71 and an X-axis drive mechanism 72 mounted on the Y-axis drive mechanism 71. The Y-axis drive mechanism 71 includes a Y-axis linear module and a Y-axis drive motor, and the X-axis drive mechanism 72 includes an X-axis linear module and an X-axis drive motor. The Y-axis drive mechanism 71 is arranged in the front-to-back direction, and the X-axis drive mechanism 72 is arranged in the left-to-right direction. The X-axis drive mechanism 72 has a sliding bracket 73 that moves along the X-axis. The front side of the sliding bracket 73 is adapted to mount the capping mechanism 8, and the rear side of the sliding bracket 73 is adapted to mount the suction mechanism 9. The capping mechanism 8 and the suction mechanism 9 move synchronously under the drive of the XY positioning and translation mechanism 7. The sliding bracket 73 is mounted on the slide of the X-axis linear module. The Y-axis drive motor and the X-axis drive motor are respectively connected to the controller 4. The controller 4 controls the capping mechanism 8 and the suction mechanism 9 to be precisely positioned in the horizontal plane. The moving area of ​​the XY positioning translation mechanism 7 can cover the area where the ton 10 is located.

[0063] By setting up an XY positioning and translation mechanism 7, and installing the capping mechanism 8 and the suction mechanism 9 on both sides of the X-axis drive mechanism 72 in a back-to-back arrangement, the capping mechanism 8 and the suction mechanism 9 move synchronously under the drive of the XY positioning and translation mechanism 7, respectively achieving precise positioning of the capping station and the material extraction station. Compared with dispersing the capping and suction functions in different stations or using multiple independent drive devices, the above integrated layout not only simplifies the equipment structure, reduces the equipment size, and lowers manufacturing costs, but also reduces the number of drive components by sharing the XY positioning and translation mechanism 7. The synchronous movement also shortens the action connection time between capping and suction, further improving the material extraction efficiency.

[0064] See Figure 19The capping mechanism 8 is mounted on the front side of the sliding bracket 73 of the X-axis drive mechanism 72 and is adapted to perform opening and closing operations on the ton container 10. The capping mechanism 8 includes a Z-axis drive mechanism 81 mounted on the sliding bracket 73, and a capping assembly 82 mounted on the Z-axis drive mechanism 81 and movable along the Z-axis. The Z-axis drive mechanism 81 includes a Z-axis linear module 811 and a Z-axis drive cylinder 812, which is signal-connected to the controller 4. The capping assembly 82 includes a first servo motor 821, a gripper cylinder 822, and capping grippers 823 mounted on the gripper cylinder 822. The first servo motor 821 is mounted on the slide of the Z-axis drive mechanism 81. The gripper cylinder 822 is mounted on the output end of the first servo motor 821 and rotates left or right under the drive of the first servo motor 821. The capping gripper 823, driven by the gripper cylinder 822, clamps or releases the lid 101 of the ton container 10, thereby realizing the opening and closing operations of the lid 101. The capping gripper 823 is a self-centering gripper, which can adapt to different sizes of lids 101 and can automatically adjust the clamping force according to the size of the lid 101. The inner wall of the capping gripper 823 is provided with an anti-slip pad to prevent slippage during the capping process. The first servo motor 821 and the gripper cylinder 822 are respectively connected to the controller 4 via signals. In other embodiments, the capping gripper 823 can also be designed as an electric gripper.

[0065] See Figure 18 , Figures 20 to 21 In this embodiment, the suction mechanism 9 is installed on the rear side of the sliding bracket 73 of the X-direction drive mechanism 72, and is arranged back-to-back with the capping mechanism 8, with their horizontal projections not overlapping. The suction mechanism 9 includes a linear drive module 91, a suction pipe 32, a control valve 33, a first sliding seat 911, a second sliding seat 912, a third sliding seat 913, a second guide rail 914, a suction section 321, a first branch 322, a second branch 323, a discharge section 324, a coarse suction pipe 325 and a fine suction pipe 326, an upper limit sensor 92, a lower limit sensor 93, a second servo motor 94, an exhaust pipe 35, and a drain groove 36. The description of these technical features refers to the description of the corresponding technical features in Embodiment 1. The structure of the suction pipe 32 is completely consistent with the suction pipe in Embodiment 1, which can be referred to in the appendix. Figure 6 and Figure 7 The linear drive module 91 is fixedly mounted on the rear side of the sliding bracket 73. The linear drive module 91 is driven by the second servo motor 94 and connected to the controller 4 via a signal. The second servo motor 94 is mainly used for high-precision, high-response-speed automated control.

[0066] See Figure 21In this embodiment, the second guide rail 914 is arranged parallel to the linear drive module 91 and has the same guiding direction. When the material extraction pipe 32 encounters resistance during its downward movement (the resistance comes from the bottom or wall of the ton container), the material extraction pipe 32 slides upward along the second guide rail 914. Since the second guide rail 914 is arranged parallel to the linear drive module 91, the sliding direction of the material extraction pipe 32 is consistent with the direction of its force, resulting in smooth sliding and no jamming.

[0067] See Figure 22 and Figure 23 The Y-axis drive mechanism 71 is arranged in the front-to-back direction, the support frame 6 is located below the Y-axis drive mechanism 71, the rotating shaft 63 is located in front of the tilting rotating frame 62, the linear drive module 91 is arranged at an angle β from top to bottom, the upper part of the linear drive module 91 tends to the rear side, the lower part of the linear drive module 91 tends to the front side, and the linear drive module 91 is tilted from back to front. The suction port of the thin suction pipe 326 is beveled, and the bevel angle α of the beveled port is equal to the tilt angle β (i.e., α=β). When the ton 10 is in a horizontal position, the thin suction pipe 326 moves downward along the tilt angle β to the bottom of the ton 10, and the end face of the beveled port of the thin suction pipe 326 is parallel to the plane of the bottom surface of the ton 10 and approaches the bottom of the ton 10, so that the thin suction pipe 326 can cooperate with the coarse suction pipe 325 to quickly suck up materials. When the ton 10 is in a tilted and raised position, the thin suction pipe 326 moves downward along the tilt angle β to the bottom corner of the ton 10, and the beveled port of the thin suction pipe 326 is close to the arc part of the bottom corner of the ton 10. The oblique cutting angle α, the tilt angle β, and the rotation angle of the tilting rotating frame 62 relative to the fixed frame 61 can be calculated based on the opening size and position of the barrel mouth. When the ton barrel 10 is in a tilted and raised state, the thin suction pipe 326 can accurately extend through the barrel mouth to the oblique angle at the bottom of the ton barrel without contacting the barrel mouth or barrel wall. Compared with the prior art, which requires manual judgment of the position of residual material at the bottom of the barrel and manual adjustment of the suction pipe angle, this application uses the tilting and raising of the tilting rotating frame 62 to automatically concentrate the tail material to the oblique angle at the bottom of the barrel. Combined with the fixed-point suction of the thin suction pipe 326, the entire material extraction process does not require manual intervention or judgment, reducing the dependence of the material extraction operation on the operator's experience and skills. The operation is simple, the material extraction effect is stable and reliable, and it has good prospects for promotion and application.

[0068] The following is combined Figures 12 to 28 This invention provides a detailed explanation of the working process of the fully automatic material feeder.

[0069] Step S1: Transfer the ton container to the preset material extraction station. Initially, the ton container 10 is transferred by the operator to the roller conveyor 67 using a forklift or overhead crane in the workshop. The controller 4 sends a start command to the geared motor of the roller conveyor 67. When the ton container 10 is conveyed to the inlet end of the inclined rotating frame 62, the controller 4 sends a start command to the geared motor of the inclined rotating frame 62. The ton container 10 smoothly transitions from the roller conveyor 67 to the inclined rotating frame 62 and continues to be conveyed forward until it reaches the preset extraction position. At this time, the ton container 10 is in a horizontal position, the photoelectric displacement sensor is triggered and sends a signal to the controller 4, and the controller 4 sends a stop execution command to the two geared motors. The controller 4 sends a command to the limiting assembly 25, and the first cylinder limiter 651 and the second cylinder limiter 652 extend to clamp and position the ton container 10 from the front and rear sides.

[0070] Step S2: Open the lid of the tonne container. Controller 4 sends a command to XY positioning and translation mechanism 7, causing Y-axis drive mechanism 71 and X-axis drive mechanism 72 to work together to drive sliding bracket 73 to move, thus moving capping mechanism 8 above the ton container lid (e.g., Figure 22 As shown), the XY positioning and translation mechanism 7 stops moving. Subsequently, the controller 4 sends a command to the Z-axis drive mechanism 81, which drives the capping assembly 82 downwards. The capping gripper 823, driven by the first servo motor 821 and the gripper cylinder 822, clamps the lid 101 and rotates it, completing the opening operation. After opening, the Z-axis drive mechanism 81 drives the capping assembly 82 to reset upwards. During the material extraction process, the capping gripper 823 keeps the lid 101 firmly clamped and does not release it (this must continue until the lid closing process).

[0071] Step S3: First material intake Controller 4 sends a command to XY positioning and translation mechanism 7, driving suction mechanism 9 to move directly above the opening of the ton container (e.g., Figure 24 (As shown). Then, the linear drive module 91 is activated. The first sliding seat 911 drives the second sliding seat 912 and the suction pipe 32 to slide downwards simultaneously. The coarse suction pipe 325 and the fine suction pipe 326 move along an inclined angle β through the barrel opening into the ton container. The suction port of the suction pipe 32 extends into the barrel opening and submerges below the liquid surface. The controller 4 sends a start command to the suction pump and simultaneously opens the pneumatic ball valve and control valve 33. The control valve 33 opens the first branch, and the coarse suction pipe 325 and the fine suction pipe 326 simultaneously suck up material. During the suction process, the linear drive module 91 controls the suction pipe 32 to descend at a uniform speed according to the suction rate of the suction pump, ensuring that the suction port of the suction pipe 32 is always kept at an appropriate position below the liquid surface. When the suction port of the suction pipe 32 reaches the bottom of the ton container (e.g., ...), Figure 25As shown in the figure, at this point, most of the material in the ton container has been extracted, and only a small amount of tailings remain at the bottom of the ton container (the liquid level in the container drops below the suction port of the coarse suction pipe), thus completing the first suction.

[0072] Step S4: Lift the suction mechanism upwards. When the suction port of the aforementioned suction pipe 32 reaches the bottom of the ton container, the lower limit sensor 93 is triggered, sending a signal to the controller 4. The controller 4 controls the second servo motor 94 to reverse, and the linear drive module 91 to drive in the opposite direction, causing the suction pipe 32 to move upward. The coarse and fine suction pipes simultaneously exit the ton container, and the upward movement speed of the suction pipe 32 can be greater than its downward movement speed. When the first sliding seat 911 moves upward and triggers the upper limit sensor 92, the linear drive module 91 stops driving upward, and the suction mechanism 9 separates from the opening of the ton container 10.

[0073] Step S5: Tilt the container to one side The controller 4 sends a command to the telescopic mechanism 66, which then actuates, driving the tilting rotating frame 62 to rotate relative to the fixed frame 61 around the rotation axis of the rotating shaft 63. Once the tilting rotating frame 62 rotates to a preset tilt angle, the controller stops the telescopic mechanism 66, causing the ton container 10 to tilt and rise to one side. At this point, the ton container 10 is in a tilted and raised state, and the remaining liquid at the bottom of the container flows towards the angled area at the bottom of the ton container under gravity. During the tilting and raising process, the first cylinder limiter 651 and the second cylinder limiter 652 remain extended to prevent the ton container 10 from shifting laterally or tipping over.

[0074] Step S6: Second feeding After the ton container 10 tilts to the preset tilt angle, the controller 4 sends a command to the XY positioning and translation mechanism 7 to adjust the moving position of the extraction pipe 32 and move the extraction pipe 32 back to directly above the ton container opening (e.g., Figure 26 (As shown). Subsequently, the linear drive module 91 is restarted. The first sliding seat 911 drives the second sliding seat 912 and the suction pipe 32 to slide downwards simultaneously. The suction pipe 32 moves downwards again, and the thin suction tube 326 of the suction pipe 32 extends downwards at an inclined angle into the barrel opening and moves towards the inclined angle of the bottom of the barrel. When the suction port of the thin suction tube 326 abuts against the inclined angle of the bottom of the barrel (the junction of the barrel wall and the bottom of the barrel), the resistance at the inclined angle of the bottom of the barrel causes the suction pipe 32 to slide upwards along the second guide rail 914, so that the suction pipe 32 will not puncture the bottom of the barrel. The upward movement of the suction pipe 32 will drive the second sliding seat 912 to move upwards relative to the third sliding seat 913, thereby triggering the photoelectric sensor to control the second servo motor 94 of the linear drive module 91 to stop rotating. The suction pipe 32 no longer descends and maintains its current position in contact with the bottom of the barrel. At this time, the inclined end of the thin suction tube 326 is close to the arc part of the inclined angle of the bottom of the barrel (e.g. Figure 27 (As shown). Start the material pump and open the pneumatic ball valve, and close the control valve 33 (the coarse suction pipe 325 stops suction). Only the tail material remaining at the bottom angle of the ton container is sucked through the fine suction pipe 326 until the tail material is completely sucked out, thus completing the second suction.

[0075] Step S7: The suction mechanism lifts again, the container returns to its original position, and the lid is closed. After the second suction is completed, controller 4 shuts off the suction pump and pneumatic ball valve, and controls the second servo motor 94 of linear drive module 91 to reverse again. Linear drive module 91 drives suction pipe 32 to move upward again, and the coarse suction pipe and fine suction pipe simultaneously exit the ton container until the upper limit sensor 92 on the upper part of linear drive module 91 is triggered, the second servo motor 94 stops rotating, and suction mechanism 9 separates from the opening of ton container 10 again and returns to its initial position. Controller 4 sends a reverse command to telescopic mechanism 66, and telescopic mechanism 66 moves in the opposite direction, driving tilting rotating frame 122 to rotate in the opposite direction relative to fixed frame 11 around the rotation axis of rotating shaft 13, so that ton container 10 returns from the tilted and raised state to the horizontal placement state.

[0076] Subsequently, controller 4 sends a command to XY positioning and translation mechanism 7 to move capping mechanism 8 back to directly above the opening of the ton container. Z-axis drive mechanism 81 drives capping assembly 82 downward, and capping gripper 823, driven by first servo motor 821 and gripper cylinder 822, tightens the lid 101, completing the capping operation. After capping, controller 4 sends a command to limit assembly 25, causing first cylinder limiter 651 and second cylinder limiter 652 to retract, releasing the grip on ton container 10. Controller 4 sends a reverse rotation command to the reduction motors of roller conveyor 67 and tilting rotating frame 62, conveying the empty ton container 10 out of the preset extraction station, completing the entire extraction process. Thus, a complete fully automatic extraction cycle ends.

[0077] It should be noted that in this second embodiment, after the first suction is completed, the suction pipe 32 does not need to be lifted up and separated from the opening of the ton 10. It is only necessary to calculate the flipping trajectory of the tilting rotating frame 62 and the moving trajectory of the suction mechanism 9 driven by the XY positioning translation mechanism 7. The suction end of the suction pipe 32 is always located inside the ton. When the ton 10 is tilted to the preset flipping angle, the suction end of the thin suction pipe 326 can also reach the bottom angle of the ton to improve the suction efficiency.

[0078] In this second embodiment, the controller 4 is connected to the roller conveyor 67, support frame 6, XY positioning and translation mechanism 7, capping mechanism 8, and suction mechanism 9 via signal connection. Following a preset material extraction process, it sequentially issues execution commands to each actuator, achieving fully automated operation from conveying, positioning, opening, extraction, and closing of the ton container 10. The entire extraction process requires no manual intervention, completely changing the traditional reliance on manual operation for material extraction machines. It fundamentally eliminates the high labor intensity, low efficiency, and safety hazards caused by manual insertion and removal of extraction tubes, as well as the proximity of personnel to hazardous chemicals. It is particularly suitable for extraction operations of hazardous chemicals with irritating odors, corrosive properties, or flammable and explosive characteristics in the chemical industry, significantly improving the safety and automation level of extraction operations.

[0079] This invention describes the material extraction process step-by-step through two embodiments, specifically dividing the extraction process into two stages: a first extraction and a second extraction. An intermediate step of "lifting the suction mechanism, tilting the ton container, and then submerging again" is incorporated between the two extractions, forming a two-stage extraction strategy: "first, horizontal extraction of material from the ton container, then tilting to extract the remaining material." The first extraction occurs with the ton container horizontal, and the suction end of the suction mechanism submerges to contact the bottom of the ton container, enabling rapid and efficient extraction of the main material inside (continuous extraction until it is difficult to extract any more material). This stage involves a large extraction volume and high efficiency. Subsequently, the suction mechanism is lifted upwards to avoid interference from the ton container opening and walls during tilting. The ton container is then tilted to one side, causing the remaining material to flow towards the lowest angled part of the bottom of the container under gravity. During the second submersion, the suction end of the suction mechanism moves to the bottom angled part of the ton container, thoroughly extracting the accumulated material there. Compared to the existing "single-time extraction" method, this invention uses a combination of two submersion and intermediate tilting steps. The first extraction is responsible for the efficient extraction of the main material, while the second extraction is specifically for the targeted removal of tailings at the bottom of the bucket. The two extraction steps perform their respective functions without interfering with each other, ensuring the extraction speed under normal working conditions and achieving thorough removal of residual material at the bottom of the bucket through the dedicated secondary extraction step. This method has good economic efficiency and practicality.

Therefore, although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention.
