Description

Technical Field

[0001] This invention relates to the technical field of grain and oil filling, and in particular to an induction-type grain and oil filling device. Background Technology

[0002] Grains and oils are a collective term for grains, beans, and other food and oilseeds, as well as their processed and semi-processed products. They are necessities in human life. With the continuous development of society, the demand for grains and oils is constantly increasing. This has prompted many small oil mills to grow into large enterprises. In order to meet market demand, enterprises must increase productivity and improve production efficiency. As enterprises grow larger, it means that they have already gained a certain reputation and brand influence in the oil industry. All of this means that edible oil manufacturers not only need to increase efficiency but also ensure quality. A qualified grain and oil filling machine can produce and fill a large amount of edible oil per hour, which improves the production efficiency of edible oil and reduces labor costs.

[0003] In existing grain and oil filling processes, such as Chinese Patent No. CN216943637U, an automated rapid grain and oil filling device is disclosed, including an oil storage tank and a lifting assembly. An electromagnetic valve is installed at the bottom oil outlet of the oil storage tank, which is connected to an oil delivery hose. The bottom of the oil delivery hose is connected to an oil filling nozzle. The lifting assembly drives the oil filling nozzle to rise and fall via the oil delivery hose. The device also includes a rotating assembly, a second transmission assembly, a first transmission assembly, and a moving assembly. The moving assembly pushes the filled oil drum onto the first transmission assembly. A guide plate is provided between the rotating worktable and the first transmission assembly, allowing the oil drum to slide onto the first transmission assembly via the guide plate. This invention, through the lifting assembly, rotating assembly, second transmission assembly, first transmission assembly, and moving assembly, achieves mechanized operation of grain and oil filling, avoiding the inconvenience of manual labor and further improving the efficiency of grain and oil packaging. This utility model has a simple and reasonable structural design, is convenient and quick to use, and has strong practicality.

[0004] The aforementioned prior art mainly achieves mechanized operation of grain and oil filling through lifting components, rotating components, second transmission components, first transmission components, and moving components, avoiding the inconvenience of manual operation and further improving the efficiency of grain and oil filling. However, the aforementioned prior art does not consider the possible shaking and tipping of oil drums during transportation. The opening of the oil drum is not large. If the oil drum shakes during transportation and causes a positional shift, it is very likely that the oil conveying equipment will not be able to align with the opening of the oil drum, resulting in oil leakage. In addition, the grain and oil filling process will also cause impact on the relatively light oil drum, causing the oil drum to shake or even tip over. In addition, the oil filling nozzle in the aforementioned technology is an ordinary metal nozzle. When filling stops, grain and oil may drip, causing resource waste and equipment pollution. Based on this, the aforementioned prior art still has room for improvement. Summary of the Invention

[0005] To clamp the oil drums and ensure their stability during transportation and filling, this application provides an induction-type grain and oil filling device that adopts the following technical solution:

[0006] An induction-type grain and oil filling device includes a mounting platform, a suspension, an input module, an output module, a worktable, a mounting housing, and a filling module. The input module, the worktable, and the output module are arranged sequentially from left to right on the mounting platform. The worktable has a stepped structure with the left side higher than the right side. The mounting housing is mounted on the top of the mounting platform via a suspension. The filling module is arranged between the mounting housing and the worktable.

[0007] The filling module includes a support column, a rotating disk, a transport mechanism, an air suction mechanism, a stabilizing mechanism, a weight sensing mechanism, and a filling mechanism. A support column is provided between the mounting housing and the workbench. A transport mechanism is rotatably mounted on the outer periphery of the support column. The transport mechanism is responsible for transferring the oil drums entering the filling module. Air suction mechanisms are evenly distributed inside the transport mechanism. A rotating disk is rotatably mounted on the top inner wall of the mounting housing. Stabilizing mechanisms that cooperate with the air suction mechanisms are evenly distributed between the rotating disk and the transport mechanism. The stabilizing mechanisms position the oil drums and ensure their stability. A weight sensing mechanism is provided on the front side above the workbench. A filling mechanism that cooperates with the weight sensing mechanism is provided on the upper end of the support column.

[0008] Preferably, the input module includes a base, a conveyor belt, and a protective plate. The base is located on the left side of the mounting platform, and the conveyor belt is installed on the base. The conveyor belt is used to transport oil drums. Protective plates are installed on the front and rear sides of the base through connectors. The protective plates are used to limit and guide the oil drums to prevent them from tipping over or falling during transport on the conveyor belt.

[0009] Preferably, the transport mechanism includes a rotating sleeve and a transport component. The rotating sleeve is rotatably mounted on the outer periphery of the support column. The rotating sleeve is electrically driven. The bottom of the rotating sleeve is provided with a transport component. The circular transport component has evenly spaced transport grooves. The transport grooves serve to limit the movement of the oil drum. The transport grooves correspond one-to-one with the air suction mechanism.

[0010] Preferably, the air suction mechanism includes a movable plate, a compression spring, a telescopic cylinder, a sliding member, a suction cup assembly, an air pump, a trigger, a pressing member, and a button. The movable plate is slidably mounted inside the transport component. A compression spring connects the movable plate to the inner wall of the transport component, serving a reset function. A telescopic cylinder is located inside the movable plate, and a sliding member is connected to the output end of the telescopic cylinder. The sliding member is slidably mounted on the movable plate. A suction cup assembly is connected to the outer side of the sliding member, adsorbing and positioning the oil drum. An air pump is located on the inner side of the upper end of the movable plate, connected to the suction cup assembly via an elastic hose. A trigger is located in the middle of the suction cup assembly, and a pressing member that cooperates with the trigger is slidably mounted on the side wall of the transport trough. A reset spring connects the pressing member to the transport component, serving a reset function. A button that cooperates with the pressing member is located inside the transport component; the button is a delay button.

[0011] Preferably, the stabilizing mechanism includes a guide column, a positioning element, a slider, and a push-pull cylinder assembly. A guide column connects the rotating disk and the transport component, serving as a guide. A slider is slidably mounted on the guide column, and a positioning element is positioned between the sliders to limit the movement of the oil drum. A push-pull cylinder assembly is mounted on the rotating disk, with its output end connected to the slider. The push-pull cylinder assembly is electrically connected to a button, which is a time-delay switch. When the button is not pressed, the push-pull cylinder assembly does not operate. When the button is pressed, the push-pull cylinder assembly starts operating. When the pressed button is released, the push-pull cylinder assembly resets and stops operating after a short delay.

[0012] Preferably, the weight sensing mechanism includes a sliding column, a pressure plate, a support spring, a linkage plate, a pressure-bearing component, and a return spring. A mounting groove is provided at the front end of the worktable. A sliding column is slidably mounted in the mounting groove. A support spring connects the sliding column to the mounting groove, serving a reset function. A pressure plate is provided at the top of the sliding column. A linkage plate is slidably mounted on the rear side of the mounting groove. A return spring connects the linkage plate to the mounting groove, serving a reset function. A pressure-bearing component that cooperates with the pressure plate is provided on the front side of the linkage plate. The rear side of the linkage plate is connected to the filling mechanism.

[0013] Preferably, the filling mechanism includes an oil pump, a guide pipe, a sealing ball, a linkage rod, and a nozzle assembly. A guide pipe is provided on the front side of the top of the support column, and an oil pump is provided inside the top of the support column. The output end of the oil pump is connected to the guide pipe through the oil pump. The oil pump pumps the grain and oil into the guide pipe through the oil pump. A nozzle assembly is provided on the lower front side of the guide pipe, and a hidden cavity is provided on the upper rear side of the guide pipe. A sealing ball is slidably arranged in the hidden cavity. The sealing ball plays a role in sealing the guide pipe. A linkage rod is provided at the bottom of the sealing ball, and the bottom end of the linkage rod is connected to the rear end face of the linkage plate.

[0014] Preferably, the nozzle assembly includes an outer nozzle, an inner nozzle, a plug, a connecting rod, a lever, and a support block. The outer nozzle is located on the lower front end of the guide pipe, and the inner nozzle is slidably mounted inside the outer nozzle. The inner nozzle and the outer nozzle slide against each other, and relative sliding only occurs between them under external forces other than gravity. The plug, which cooperates with the inner nozzle, is located inside the outer nozzle. In its initial state, the plug blocks and seals the inner nozzle. The top of the inner nozzle is connected to the connecting rod via a pin, and the top of the connecting rod is connected to the front end of the lever via a pin. The right end of the lever is sleeved on the outer periphery of the linkage rod, and the middle of the lever is connected to the support block via a pin. The support block is the fulcrum of the lever and is located on the inner wall of the guide pipe.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. The inductive grain and oil filling device of the present invention, by positioning and clamping the oil drum, avoids the oil drum from shaking during transportation, which may cause misalignment between the drum opening and the filling head, or the oil drum may be unstable due to impact during filling, which may cause the oil drum to tip over. In addition, the present application adaptively controls the filling rate by gravity sensing, and the filling process is fast at first and then slows down to avoid the grain and oil overflowing due to the filling being too fast and not stopping in time, which may cause waste of resources and contamination of the work surface and the body of the oil drum.

[0017] 2. Positioning: The oil drum contacts and is attracted to the suction cup assembly. Then, the telescopic cylinder drives the suction cup assembly to retract via the sliding part, moving the oil drum to the designated position. At the same time, the triggering part retracts along with the suction cup assembly. After retraction, the triggering part squeezes the pressing part, causing the pressing part to press the button. A circuit is formed between the button and the push-pull cylinder assembly. The push-pull cylinder assembly pushes the slider downward, and the positioning part moves to the outer periphery of the oil drum, thus stabilizing and limiting the oil drum. By positioning first and then limiting, the position of the oil drum is precisely controlled, avoiding misalignment between the oil drum opening and the filling head. Moreover, the positioning part is always around the oil drum during the filling process, eliminating the impact of grain and oil on the oil drum during filling and preventing the oil drum from tipping over due to impact.

[0018] 3. Sensing: An empty oil drum is transported to the pressure plate. The oil pump pumps the grain and oil liquid into the guide pipe through the oil delivery pipe. Under pressure, the inner nozzle moves downward and inserts into the oil drum, separating from the plug. The grain and oil liquid is poured into the oil drum through the inner nozzle. The weight of the oil drum increases, pressing the pressure plate downward. When the pressure plate moves downward a specified distance, it contacts the pressure-bearing component and squeezes the linkage plate downward together. The sealing ball moves downward and gradually closes the guide pipe. The downward-moving sealing ball also presses the rear end of the lever downward. With the support block as the fulcrum, the front end of the lever tilts up, and the inner nozzle is pulled upward. When the pressure-bearing component descends to the lowest position, the sealing ball completely closes the guide pipe, and the inner nozzle moves upward to a position where it interlocks with the plug. This application ensures the accuracy and stability of the filling process by using a fast-then-slow filling method, avoiding grain and oil overflow. Furthermore, the use of a double-closing setting ensures that the grain and oil will not drip after filling stops, thus ensuring the cleanliness of the equipment and the outer surface of the oil drum.

[0029] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0030] This application discloses an induction-type grain and oil filling device. By positioning and clamping the oil drum to be filled, it avoids the oil drum from becoming unstable due to impact during filling, which could cause the oil drum to tip over. Furthermore, this application adaptively controls the filling rate through gravity sensing to avoid filling too quickly and not stopping in time, which could cause grain and oil to spill, resulting in resource waste and contamination of the work surface and the oil drum body.

[0031] Reference Figure 1 As shown, an induction-type grain and oil filling device includes a mounting platform 1, a suspension 2, an input module 3, an output module 4, a workbench 5, a mounting housing 6, and a filling module 7. The input module 3, the workbench 5, and the output module 4 are arranged sequentially from left to right on the mounting platform 1. The workbench 5 has a stepped structure with the left side higher than the right side. The mounting housing 6 is installed above the mounting platform 1 via the suspension 2. The filling module 7 is arranged between the mounting housing 6 and the workbench 5.

[0032] Reference Figure 3 , Figure 4As shown, the filling module 7 includes a support column 71, a rotating disk 72, a transport mechanism 73, an air suction mechanism 74, a stabilizing mechanism 75, a weight sensing mechanism 76, and a filling mechanism 77. The support column 71 is provided between the mounting housing 6 and the workbench 5. The transport mechanism 73 is rotatably mounted on the outer periphery of the support column 71. The transport mechanism 73 is responsible for transferring the position of the oil drum entering the filling module 7. The air suction mechanism 74 is evenly arranged inside the transport mechanism 73. The rotating disk 72 is rotatably arranged on the top inner wall of the mounting housing 6. The stabilizing mechanism 75, which cooperates with the air suction mechanism 74, is evenly arranged between the rotating disk 72 and the transport mechanism 73. The stabilizing mechanism 75 positions the oil drum to ensure its stability. The weight sensing mechanism 76 is provided on the upper front side of the workbench 5. The filling mechanism 77, which cooperates with the weight sensing mechanism 76, is provided on the upper end of the support column 71.

[0033] During the actual filling process, the oil drum is transported to the transport mechanism 73 via the input module 3 (at this time, the bottom surface of the oil drum is located on the high left side of the mounting platform 1). The side wall of the oil drum comes into contact with and is attracted by the air suction mechanism 74. The air suction mechanism 74 adjusts the oil drum to the designated position. At the same time, the air suction mechanism 74 triggers the stabilizing mechanism 75 to lock the position of the oil drum. Subsequently, the transport mechanism 73 drives the oil drum to adjust to the designated angle and reach the weight sensing mechanism 76. At this time, the filling mechanism 77 is located above the oil drum. Under the action of internal pressure, the filling mechanism 77 extends into the oil drum to fill the grain and oil. The oil drum is continuously weighted. When the weight of the oil drum reaches a certain value... When the drum is about to be filled, the weight sensing mechanism 76 triggers the filling mechanism 77, causing the oil delivery rate of the filling mechanism 77 to gradually decrease. When the weight of the drum reaches another fixed value (when it is full), the filling mechanism 77 is completely closed, and the air suction mechanism 74 no longer triggers the stabilizing mechanism 75. The stabilizing mechanism 75 resets after a delay (the weight sensing mechanism 76 will lower its height after being triggered, at which point the bottom of the drum is already at the same height as the right side of the mounting platform 1). The transport mechanism 73 drives the drum to adjust its angle again. After the adjustment is completed, the stabilizing mechanism 75 resets, and the air suction mechanism 74 pushes the drum into the output module 4. The output module 4 sends the drum into the next process.

[0034] Reference Figure 2As shown, this application includes an input module 3 for transporting oil drums used in grain and oil filling. The input module 3 includes a base 31, a conveyor belt 32, and a protective plate 33. The base 31 is located on the left side of the mounting platform 1, and the conveyor belt 32 is mounted on the base 31. The conveyor belt 32 is used to transport the oil drums. The protective plates 33 are installed on the front and rear sides of the base 31 through connectors. The protective plates 33 serve to limit and guide the oil drums, preventing them from tipping over or falling during transport on the conveyor belt 32. The oil drums can be transported by placing them on the conveyor belt 32. Since the oil drums used in grain and oil filling are usually lightweight plastic drums, the protective plates 33 in this application provide positioning and protection for the oil drums during transport, preventing them from tipping over or falling.

[0035] Reference Figure 3 As shown, this application includes a transport mechanism 73 for adjusting the position of the oil drum. The transport mechanism 73 includes a rotating sleeve 731 and a transport component 732. The rotating sleeve 731 is rotatably mounted on the outer periphery of the support column 71. The rotating sleeve 731 is electrically driven. The transport component 732 is located at the bottom of the rotating sleeve 731. The circular transport component 732 has evenly spaced transport grooves 733, which limit the position of the oil drum. The transport grooves 733 correspond one-to-one with the air suction mechanism 74. In actual operation, the oil drum is placed in the transport groove 733, and then the rotation of the rotating sleeve 731 causes the oil drum to move.

[0036] Reference Figures 3-6 , Figure 9As shown, the oil drums used for grain and oil filling are mostly lightweight plastic drums. These lightweight plastic drums are not stable and are easily shaken by the impact of grain and oil, which can lead to tipping over. This not only causes production delays but also wastes resources and contaminates equipment. Therefore, this application provides a suction mechanism 74 and a stabilizing mechanism 75. The suction mechanism 74 includes a movable plate 741, a compression spring 742, a telescopic cylinder 743, a sliding member 744, a suction cup assembly 745, an air pump 746, a trigger member 747, a pressing member 748, and a button 749. The movable plate 741 is slidably arranged inside the transport member 732. A compression spring 742 is connected between the movable plate 741 and the inner wall of the transport member 732. The compression spring 742 plays a resetting role. The movable plate 741 is internally designed with... A telescopic cylinder 743 is provided, and a sliding member 744 is connected to the output end of the telescopic cylinder 743. The sliding member 744 is slidably mounted on the movable plate 741. A suction cup assembly 745 is connected to the outer side of the sliding member 744. The suction cup assembly 745 adsorbs and positions the oil drum. An air pump 746 is provided on the inner side of the upper end of the movable plate 741. The air pump 746 is connected to the suction cup assembly 745 through an elastic hose. A trigger member 747 is provided in the middle of the suction cup assembly 745. A pressing member 748 that cooperates with the trigger member 747 is slidably mounted on the side wall of the transport trough 733. A return spring is connected between the pressing member 748 and the transport member 732. The return spring plays a reset role. A button 749 that cooperates with the pressing member 748 is provided inside the transport member 732. The button 749 is a delay button.

[0037] Reference Figure 3 As shown, the stabilizing mechanism 75 includes a guide column 751, a positioning element 752, a slider 753, and a push-pull cylinder assembly 754. The guide column 751 is connected between the rotating disk 72 and the transport component 732, and the guide column 751 plays a guiding role. The slider 753 is slidably arranged on the guide column 751, and the positioning element 752 is arranged between the sliders 753, which plays a limiting role for the oil drum. The push-pull cylinder assembly 754 is arranged on the rotating disk 72, and the output end of the push-pull cylinder assembly 754 is connected to the slider 753. The push-pull cylinder assembly 754 is electrically connected to the button 749.

[0038] During the actual process of stabilizing the oil drum, the oil drum comes into contact with and is attracted to the suction cup assembly 745 (initially, the suction cup assembly 745 is pushed out by the telescopic cylinder 743). Then, the telescopic cylinder 743 drives the suction cup assembly 745 back through the sliding member 744, moving the oil drum to the designated position. Simultaneously, the trigger member 747 retracts along with the suction cup assembly 745. After retraction, the trigger member 747 presses the pressing member 748, causing the pressing member 748 to press the button 749. A circuit is formed between the button 749 and the push-pull cylinder assembly 754, which pushes the slider 753 downwards. The positioning member 752 moves to the outer periphery of the oil drum, thus stabilizing its position. Subsequently, the transport member 732 moves the oil drum to the weight sensing mechanism 76 at a designated angle, and the filling mechanism 77 fills the oil drum. As the weight of the oil drum increases... As the weight sensing mechanism 76 descends, the oil drum follows the weight sensing mechanism 76 and the movable plate 741 also descends with the oil drum. The trigger 747 and the pressing part 748 slide relative to each other. When the weight of the oil drum reaches a certain value (full), the filling mechanism 77 stops filling, and the trigger 747 and the pressing part 748 separate. The pressing part 748 resets under the action of the reset spring, so that it no longer presses the button 749. Since the button 749 is a time-delay switch, after the transport mechanism 73 drives the oil drum to adjust the angle, the push-pull cylinder assembly 754 resets. Subsequently, the telescopic cylinder 743 pushes out the full oil drum, the air pump 746 stops working, the suction of the suction cup assembly 745 disappears, and the output module 4 outputs the full oil drum to the next process. After the oil drum is transported away, the weight sensing mechanism 76 resets, and the movable plate 741 resets under the action of the compression spring 742.

[0039] Reference Figure 3 , Figure 6 As shown, the amount of grain and oil in the oil drum increases continuously during filling. When the drum reaches its maximum capacity, it needs to be closed promptly to prevent overflow and waste. Therefore, this application includes a weight sensing mechanism 76 and a filling mechanism 77. The weight sensing mechanism 76 includes a sliding column 761, a pressure plate 762, a support spring 763, a linkage plate 764, a pressure-bearing component 765, and a return spring 766. A mounting groove is provided at the front end of the workbench 5, and the sliding column 76 is slidably mounted vertically within the mounting groove. 1. A support spring 763 is connected between the sliding column 761 and the mounting groove. The support spring 763 plays a reset role. A pressure plate 762 is provided at the top of the sliding column 761. A linkage plate 764 is slidably provided on the rear side of the mounting groove. A return spring 766 is connected between the linkage plate 764 and the mounting groove. The return spring 766 plays a reset role. A pressure-bearing component 765 that cooperates with the pressure plate 762 is provided on the front side of the linkage plate 764. The rear side of the linkage plate 764 is connected to the filling mechanism 77.

[0040] Reference Figure 3 , Figure 6 , Figure 7 , Figure 8 As shown, the filling mechanism 77 includes an oil pump 771, a guide pipe 772, a sealing ball 773, a linkage rod 774, and a nozzle assembly 775. The guide pipe 772 is provided on the front side of the top of the support column 71, and the oil pump 771 is provided inside the top of the support column 71. The output end of the oil pump 771 is connected to the guide pipe 772 through an oil pipe. The oil pump 771 pumps the grain and oil into the guide pipe 772 through the oil pipe. The nozzle assembly 775 is provided on the lower front side of the guide pipe 772, and a hidden cavity is provided on the upper rear side of the guide pipe 772. The sealing ball 773 is slidably arranged in the hidden cavity. The sealing ball 773 plays a sealing role for the guide pipe 772. The linkage rod 774 is provided at the bottom of the sealing ball 773, and the bottom end of the linkage rod 774 is connected to the rear end face of the linkage plate 764.

[0041] Reference Figure 7 , Figure 8 As shown, the nozzle assembly 775 includes an outer nozzle 7751, an inner nozzle 7752, a plug 7753, a connecting rod 7754, a lever 7755, and a support block 7756. The outer nozzle 7751 is located on the lower front end of the guide pipe 772. The inner nozzle 7752 is slidably disposed inside the outer nozzle 7751. The inner nozzle 7752 and the outer nozzle 7751 slide against each other; relative sliding only occurs between the inner nozzle 7752 and the outer nozzle 7751 under external forces other than gravity. The inner nozzle 7752 cooperates with... The plug 7753 is located inside the outer nozzle 7751. In the initial state, the plug 7753 blocks and seals the inner nozzle 7752. The top of the inner nozzle 7752 is connected to the connecting rod 7754 by a pin. The top of the connecting rod 7754 is connected to the front end of the lever 7755 by a pin. The right end of the lever 7755 is sleeved on the outer periphery of the linkage rod 774. The middle part of the lever 7755 is connected to the support block 7756 by a pin. The support block 7756 is the fulcrum of the lever 7755. The support block 7756 is located on the inner wall of the guide pipe 772.

[0042] During the actual filling process, the empty oil drum is transported to the pressure plate 762 (the initial height of the pressure plate 762 is the same as the height of the left side of the workbench 5). The oil pump 771 pumps the grain and oil liquid into the guide pipe 772 through the oil delivery pipe. At this time, the inner nozzle 7752 is blocked by the plug 7753, so the pressure in the guide pipe 772 continuously rises. Under the action of pressure, the inner nozzle 7752 moves downward and inserts into the oil drum, and separates from the plug 7753. The grain and oil liquid is poured into the oil drum through the inner nozzle 7752. As the amount of grain and oil in the oil drum increases, the mass of the oil drum continuously increases and forces the pressure plate 762 to move downward. When the pressure plate 762 moves downward a specified distance (at this time, the oil drum is about to be filled), the pressure plate 762 contacts the pressure receiving component 765 and squeezes the linkage plate 764. Together, they move downwards. Under the action of the linkage rod 774, the sealing ball 773 moves downwards and gradually closes the guide pipe 772. The downward-moving sealing ball 773 will also press the rear end of the lever 7755 downwards. With the support block 7756 as the fulcrum, the front end of the lever 7755 tilts up. Under the action of the connecting rod 7754, the inner nozzle 7752 is pulled upwards. When the pressure member 765 descends to the lowest position (at this time, the oil tank is full, and the height of the pressure member 765 is the same as the height of the lower right side of the workbench 5), the sealing ball 773 completely closes the guide pipe 772. The inner nozzle 7752 moves upwards to the position where it blocks and cooperates with the plug 7753. After that, the filled oil tank is transported to the next process. The pressure plate 762 is reset under the action of the support spring 763, and the sealing ball 773 is reset.

[0043] The implementation principle of this embodiment is as follows:

[0044] (1): Input module 3 delivers the empty oil drum to transport mechanism 73;

[0045] (2): The side wall of the oil drum comes into contact with the air suction mechanism 74 and is adsorbed. The air suction mechanism 74 adjusts the oil drum to the designated position. At the same time, the air suction mechanism 74 triggers the stabilizing mechanism 75 to lock the position of the oil drum. Subsequently, the transport mechanism 73 drives the oil drum to adjust the designated angle to reach the weight sensing mechanism 76.

[0046] (3): The oil pump 771 pumps the grain and oil liquid into the guide pipe 772 through the oil pipeline. Under the action of pressure, the inner nozzle 7752 moves downward and inserts into the oil drum, and the inner nozzle 7752 separates from the plug 7753. The grain and oil liquid is poured into the oil drum through the inner nozzle 7752. The mass of the oil drum increases continuously and presses the pressure plate 762 to move downward. When the pressure plate 762 moves downward a specified distance, the pressure plate 762 contacts the pressure-bearing component 765 and squeezes the linkage plate 764. Together they move downwards, the sealing ball 773 moves downwards and gradually closes the guide tube 772, and the downward-moving sealing ball 773 will press the rear end of the lever 7755 to move downwards. With the support block 7756 as the fulcrum, the front end of the lever 7755 tilts up, and the inner nozzle 7752 is pulled upwards. When the pressure member 765 descends to the lowest position, the sealing ball 773 completely closes the guide tube 772, and the air suction mechanism 74 no longer triggers the stabilizing mechanism 75. The stabilizing mechanism 75 resets after a delay.

[0047] (4): The transport mechanism 73 drives the oil drum to adjust the angle again. After the adjustment is completed, the stabilizing mechanism 75 resets, and the air suction mechanism 74 pushes the oil drum into the output module 4 and then resets.

[0048] (5): Output module 4 sends the oil drum to the next process.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
