Abstract
Description
Technical Field
[0001] This invention relates to the field of material distribution equipment technology, and more specifically to the field of automatic four-part sampling device for energetic powders. Background Technology
[0002] Energetic materials are compounds or mixtures containing explosive groups or oxidizers and combustibles that can independently undergo chemical reactions and output energy. They are an important component of military explosives, propellants, and rocket propellant formulations.
[0003] Early black powder, traditional nitro explosives such as trinitrotoluene, nitrate ester explosives such as nitroglycerin, nitramine explosives such as RDX and octogen, high-density, high-nitrogen compounds such as trinitroazacyclobutane, hexanitrohexaazaisowulzane, diaminodinitroethylene, and octanitrocuboethane, and high-energy propellants such as polyazidoglycidyl ether all fall under the category of energetic materials. Current research hotspots in energetic materials are ultra-high-energy materials. These materials refer to novel high-energy substances with energy levels at least one order of magnitude higher than conventional explosives (typically 10³ J / g), reaching 10⁴ J / g to 10⁵ J / g, or even above 10⁵ J / g, such as metallic hydrogen, all-nitrogen compounds, and high-stretch bond energy release materials (such as nano-aluminum).
[0004] Bulk density refers to the density obtained by dividing the mass of a powder by the volume V of the container it occupies, also known as bulk density, i.e., ρb = W / V. When testing energetic powder materials, it is necessary to measure their bulk density. Currently, the bulk density of energetic powder materials is usually measured by manually dividing the material randomly into several portions and then measuring the bulk density of each portion. However, due to the flammable and explosive properties of energetic powder materials, manual portioning presents safety hazards and low efficiency. Some portioning equipment also exists, such as the technology disclosed in existing patents:
[0005] Patent publication number CN109795752A, entitled "A Material Distributing Device," discloses the following: A material distributing device includes a distributor and a receiving and transferring mechanism located below the distributor. The distributor comprises a feed hopper and multiple distributing pipes communicating with the feed hopper, with the upper ends of the distributing pipes connected in an arched shape. The receiving and transferring mechanism includes a base, a receiving hopper, a cylinder, and a discharge hopper. The base has a mounting groove in its center, the cylinder is placed in the mounting groove, and a push plate is mounted on the cylinder's drive rod. The number of receiving hoppers is the same as the number of distributing pipes, and they are located below the distributing pipes. The base has support columns for mounting the receiving hoppers, with the support columns positioned opposite each other on both sides of the receiving hopper, and the upper end of the support column hinged to the receiving hopper. The lower end of the receiving hopper has a discharge pipe. This material distributing device, employing the technical solution of this invention, can automatically measure the weight of the material and achieve automatic material transfer, offering the advantage of high distributing efficiency.
[0006] The material dispensing equipment mentioned above is all automated to a certain extent, but requires manual feeding of materials at the inlet. Since energetic powder materials are flammable and explosive, there are safety hazards. Summary of the Invention
[0007] The purpose of this invention is to address the technical problems of low automation and safety hazards in the material distribution equipment when measuring the bulk density of energetic powder materials. This invention provides an automatic four-part sampling device for energetic powders.
[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution:
[0009] An automatic four-part sampling device for energetic powders includes a support base, a material holding component, a material dispensing component, a tilting and unloading component, a lifting component, and a material retrieval component. A material carrying tray is placed on the material holding component. The material holding component, the material retrieval component, and the lifting component are all mounted on the support base. The tilting and unloading component is located on the lifting component. The material dispensing component is connected to the tilting and unloading component. The material holding component and the material retrieval component are both located below the material dispensing component. The material holding component cooperates with the tilting and unloading component to realize material feeding. The material retrieval component cooperates with the upright material dispensing component to realize material unloading.
[0010] In this solution, the material distribution system eliminates the need for manual material distribution, ensuring safety, and boasts advantages such as high automation and significantly improved distribution efficiency. Initially, the distribution component is positioned upright (vertically). Material is placed in the material carrier tray (automatic feeding can be achieved through external equipment), and then the material carrier tray is placed on the receiving component. The dispensing component then rotates the distribution component 180° to an inverted position. A lifting component lowers the inverted distribution component until it contacts the material carrier tray, which is then secured back onto the distribution component. The dispensing component then rotates the distribution component another 180° back to its upright position. At this point, the material from the carrier tray enters the distribution component, achieving material loading and distribution. Finally, the material is unloaded through the cooperation of the distribution component and the picking component. Both the front and back ends of this distribution system can be equipped with automated equipment to further enhance automation.
[0011] In addition, the support base is a square plate, and shock-absorbing feet with braking mechanisms are provided at the four corners of the bottom of the square plate.
[0012] Furthermore, the material distribution assembly includes a material distribution cavity, a material distribution bin located below the material distribution cavity, a material distribution assembly plate located inside the material distribution cavity, and a material discharge mechanism located at the lower end of the material distribution bin for controlling the discharge. The material distribution assembly plate extends beyond the upper edge of the material distribution cavity to cooperate with the material carrying plate. Multiple clamping mechanisms for clamping the material carrying plate are evenly distributed on the outer wall of the material distribution cavity.
[0013] This solution introduces a preferred structure for the material distribution assembly. This structure has the advantages of reasonable structure, simple operation, and low assembly and manufacturing cost. After the material distribution assembly is flipped, the material distribution plate cooperates with the material carrying plate to divide the material on the material carrying plate into portions. The clamping mechanism after the material distribution assembly is flipped is used to clamp the material carrying plate. When the shape of the material distribution cavity is circular, the clamping mechanism consists of multiple clamping cylinders evenly distributed around the circumference of the outer edge of the material distribution cavity. The number of clamping cylinders can be selected as four.
[0014] Furthermore, the material holding assembly includes a support frame for placing the material carrier tray, the material carrier tray being adapted to the size of the dispensing cavity, and the edge of the material carrier tray having an outwardly inclined bevel with an inclination angle ranging from 3° to 5°.
[0015] This solution introduces a preferred structure for the material holding assembly, which boasts advantages such as reasonable structure, simple operation, and low assembly and manufacturing costs. Before material distribution, the material carrier tray is placed on the support frame. After the distribution assembly is flipped, a lifting component brings the top of the distribution assembly into contact with the material carrier tray. A clamping mechanism then clamps the material carrier tray onto the distribution assembly, allowing for subsequent material distribution. Alternatively, this material holding assembly can also be any other structure that achieves the design objectives.
[0016] The clamping mechanism uses a cylinder chuck structure for gripping, and the material carrier plate has a 3°~5° bevel (the diameter of the material carrier plate is smaller at the bottom and larger at the top), which makes it less likely for the material carrier plate to fall after being gripped.
[0017] Furthermore, the material distribution bin includes four symmetrically arranged material distribution funnels, and the material distribution assembly plate includes a "cross" shaped plate, which overlaps with the top edge of the four material distribution funnels, and the "cross" shaped plate extends out of the upper edge of the material distribution cavity.
[0018] This solution discloses a shape and layout of a material distribution bin, as well as a shape and specific location of a material distribution assembly plate. The solution utilizes the principle of the quartering method, randomly pouring a portion of material into a material carrying tray. The material in the material carrying tray is completely divided into four portions by mutually perpendicular dividers in a "cross" shaped plate. The four portions of material are then sent to the back-end processing, where the bulk density is analyzed and measured.
[0019] Furthermore, the feeding mechanism includes a mounting plate, multiple discharge cylinders mounted on the mounting plate, and a feeding control component that controls the synchronous feeding of all discharge cylinders. The mounting plate is fixedly installed at the discharge port of the distribution bin, and the number of discharge cylinders is the same as that of the distribution bin and they correspond one-to-one.
[0020] This solution introduces a preferred structure for the feeding mechanism, which has the advantages of reasonable structure, simple operation, and low assembly and manufacturing cost. During operation, materials enter the corresponding discharge cylinders of the feeding mechanism from the discharge ports of the distribution bin, and the feeding mechanism controls whether the corresponding discharge cylinder discharges material. Alternatively, this feeding mechanism can also be any other structure that can achieve the design objectives.
[0021] Furthermore, each material discharge control component includes a control box, a draw plate, and a first drive mechanism. The control box is located below the mounting plate. The upper part of the control box is connected to the discharge port of the corresponding material distribution bin, and the lower part of the control box is connected to the corresponding discharge cylinder. A sliding plate outlet is opened on one side of the control box. The draw plate is slidably inserted into the control box through the sliding plate outlet. The first drive mechanism controls the reciprocating motion of the draw plate to realize the opening and closing of the corresponding discharge cylinder.
[0022] This solution introduces a preferred structure for the material feeding control component. This structure has the advantages of reasonable structure, simple operation, and low assembly and manufacturing costs. Alternatively, other structures that can achieve the design objectives can also be used. Specifically, the first drive mechanism in this solution is a drive cylinder. The cylinder body is fixed below the mounting plate, and the piston end of the drive cylinder is connected to the corresponding slide outlet. The draw plate is made of polytetrafluoroethylene (PTFE) to reduce frictional resistance.
[0023] Furthermore, the draw plate is located outside the slide plate outlet. The first drive mechanism is connected to the draw plate located outside the slide plate outlet. The first drive mechanism is fixed on the mounting plate. The fit between the slide plate outlet and the draw plate is a clearance fit, and the width of the clearance is smaller than the particle size of the material.
[0024] This solution details the connection form and positional relationship between the draw plate and the first drive mechanism. In addition, the size of the draw plate needs to be larger than the size of the discharge cylinder. This size design can effectively realize the opening and closing of the discharge cylinder and avoid incomplete opening and closing of the discharge cylinder. The width of the gap between the slide outlet and the draw plate is smaller than the particle size of the material. The design purpose is to prevent the draw plate from carrying out the material in the control box when it enters and exits, thus avoiding material waste.
[0025] Furthermore, the material handling component includes a movable base, multiple material cups disposed on the movable base, and a translational pushing mechanism that drives the movable base to move. The number of material cups is the same as the number of discharge ports of the material dispensing component, and the movable base can extend to the bottom of the material holding component.
[0026] In this design, the movable base extends directly below the support frame of the material holding component. The movable base moves multiple material cups to be positioned directly below the support frame. When the material carrier plate of the material holding component is removed by the dispensing component, there is no need to move the position of the dispensing component. Simply flipping it over is sufficient to load and unload the material. This arrangement improves work efficiency. After the dispensing component finishes unloading, the translation and pushing mechanism retracts, simultaneously moving the movable base and the multiple material cups on it out of the support frame, facilitating subsequent testing of the material bulk density.
[0027] In addition, the translation and pushing mechanism is one of the following: translation cylinder, translation oil cylinder, translation electric cylinder or translation lead screw, which is horizontally set on the support base. It can also be other drive mechanisms that can achieve linear drive.
[0028] Furthermore, the lifting assembly includes a mounting base vertically mounted on a support base and a lifting mechanism mounted on top of the mounting base, with the lifting end of the lifting mechanism fixedly connected to the tilting and unloading assembly.
[0029] In this solution, the lifting mechanism can be selected from one of the following: lifting cylinder, lifting hydraulic cylinder, lifting electric cylinder, or lifting screw, or other lifting drive mechanism capable of lifting. The installation slot facilitates the installation of the lifting mechanism. The mounting base is a U-shaped installation slot with three baffles. The tilting and unloading component is located inside the U-shaped installation slot, which can protect the tilting and unloading component during lifting and has a stable lifting effect.
[0030] Furthermore, the tilting and unloading assembly includes a rotating component and a rotating drive mechanism. One end of the rotating component is fixedly connected to the material distribution assembly, and the other end of the rotating component is connected to the output end of the rotating drive mechanism, which is fixed on the lifting assembly.
[0031] This solution introduces a preferred structure for a tilting and unloading assembly, which features simple structure, convenient assembly, and low operating costs. Specifically, the rotating component includes a horizontally positioned rotating shaft and a connecting part at one end of the rotating shaft. The connecting part is detachably connected to the outer wall of the material distribution assembly via bolts. The other end of the rotating shaft is connected to the output end of a rotating drive mechanism. The rotating drive mechanism can be a servo motor or a reducer. The servo motor drives the reducer, and the output end of the reducer is connected to the rotating shaft. The servo motor and reducer enable precise tilting control.
[0032] Working principle:
[0033] The lifting assembly initializes to the top stop position → material is randomly poured into the material carrier tray → the material carrier tray is placed on the positioning fixture of the material holding assembly → the translational pushing device extends → the material cup is placed into the moving base → the translational pushing mechanism moves the material cup directly below the material carrier tray → the flipping and pouring assembly follows the lifting assembly down to the gripping position → the cylinder clamp of the distributing assembly extends and clamps the material carrier tray → the lifting device rises to the flipping position → the flipping and pouring assembly flips the distributing assembly and the material carrier tray to allow the material to enter the distributing assembly → the lifting assembly descends to the discharge position → the discharge port pull plate of the distributing assembly opens → the material enters the material cup → the flipping and pouring assembly follows the lifting assembly up and flips → the flipping and pouring assembly follows the lifting assembly down and repositions the material carrier tray onto the positioning fixture → the translational pushing mechanism delivers the material cup → the operator removes the material cup and repositions the empty material cup and spreads the material evenly onto the material carrier tray, then the next cycle begins.
[0034] The beneficial effects of this invention are as follows:
[0035] 1. This invention features a rational design; the material distribution system eliminates the need for manual material distribution, ensures safe distribution, and boasts a high degree of automation, significantly improving distribution efficiency. Initially, the distribution component is placed vertically in an upright position. Material is placed in the center of the material carrier tray, which is then placed on the receiving component. The dispensing component flips the distribution component 180°, and then the lifting component lowers the inverted distribution component to the appropriate height to contact the material carrier tray, securing the tray to the distribution component. The dispensing component then flips the distribution component another 180° to return it to its upright position. The distribution component enables both material loading and distribution, and the material unloading is achieved through the cooperation of the dispensing and unloading components. Automation equipment can be added to both the front and rear ends of this distribution system to further enhance automation.
[0036] 2. This invention is a fully automatic material distribution device. Except for loading and unloading, the entire process is unmanned, ensuring safety and eliminating the influence of human factors on the material bulk density.
[0037] 3. The clamping mechanism uses a cylinder chuck structure for gripping. The material carrier plate is designed with a 3°~5° bevel (the diameter of the material carrier plate is smaller at the bottom and larger at the top), so that the material carrier plate is not easy to fall off after being gripped.
[0038] 4. This invention specifically describes the connection form and positional relationship between the draw plate and the drive mechanism. In addition, the size of the draw plate needs to be larger than the size of the discharge cylinder. This size design can effectively realize the opening and closing of the discharge cylinder and avoid incomplete opening and closing of the discharge cylinder. The width of the gap between the slide outlet and the draw plate is smaller than the particle size of the material. The design purpose is to avoid the material in the control box being carried out when the draw plate enters and exits, causing material waste. Attached Figure Description

[0050] Example 1
[0051] like Figures 1 to 6 As shown, this embodiment provides an automatic four-part sampling device for energetic powders, including a support base 10, a material holding component 30, a material dispensing component 40, a tilting and pouring component 60, a lifting component 70, and a material taking component 20. A material carrying tray 50 is placed on the material holding component 30. The material holding component 30, the material taking component 20, and the lifting component 70 are all installed on the support base 10. The tilting and pouring component 60 is disposed on the lifting component 70. The material dispensing component 40 is connected to the tilting and pouring component 60. The material holding component 30 and the material taking component 20 are both located below the material dispensing component 40. The material holding component 30 cooperates with the tilting material dispensing component 40 to realize material feeding. The material taking component 20 cooperates with the upright material dispensing component 40 to realize material unloading.
[0052] In this embodiment, the material distribution system eliminates the need for manual material distribution, ensuring safety and offering advantages such as high automation and significantly improved distribution efficiency. Initially, the material distribution component 40 is positioned upright (vertically). Material is placed in the material carrier tray 50 (automatic material feeding can be achieved through external equipment). The material carrier tray 50 is then placed on the receiving component 30. The tilting and unloading component 60 rotates the material distribution component 40 180° to an inverted position. The lifting component 70 lowers the inverted material distribution component 40 until it contacts the material carrier tray 50, fixing the tray to the distribution component 40. The tilting and unloading component 60 then rotates the distribution component 40 180° back to its upright position. At this point, the material in the material carrier tray 50 enters the material distribution component 40, achieving material loading and distribution. The material is then unloaded through the cooperation of the material distribution component 40 and the picking component 20. Both the front and rear ends of this material distribution system can be equipped with automated equipment to further enhance automation.
[0053] All parts that come into contact with materials are made of stainless steel or polytetrafluoroethylene. The stainless steel is mirror polished, and all components are grounded to prevent static electricity.
[0054] Example 2
[0055] This embodiment is a further optimization based on Embodiment 1, specifically:
[0056] The material distribution assembly 40 includes a material distribution cavity 41, a material distribution bin 42 disposed below the material distribution cavity 41, a material distribution combination plate disposed inside the material distribution cavity 41, and a material discharge mechanism 43 disposed at the lower end of the material distribution bin 42 for controlling the discharge. The material distribution combination plate extends out of the upper edge of the material distribution cavity 41 and cooperates with the material carrying plate 50. Multiple clamping mechanisms for clamping the material carrying plate 50 are evenly distributed on the outer wall of the material distribution cavity 41.
[0057] This embodiment introduces a preferred structure of the material distribution component 40, which has the advantages of reasonable structure, simple operation, and low assembly and manufacturing cost. After the material distribution component 40 is flipped, the material distribution plate cooperates with the material carrying plate 50 to divide the material on the material carrying plate 50. The clamping mechanism after the material distribution component 40 is flipped is used to clamp the material carrying plate 50. When the material distribution cavity 41 is circular, the clamping mechanism consists of multiple clamping cylinders evenly distributed around the circumference of the outer edge of the material distribution cavity 41. The number of clamping cylinders can be selected as four.
[0058] Example 3
[0059] This embodiment is a further optimization based on embodiment 1 or 2, specifically:
[0060] The material holding assembly 30 includes a support frame for placing the material carrier tray 50. The material carrier tray 50 is adapted to the size of the dispensing cavity 41. The edge of the material carrier tray is provided with an outwardly inclined bevel, and the inclination angle of the bevel is in the range of 3° to 5°.
[0061] This embodiment introduces a preferred structure for the material holding assembly 30, which has the advantages of reasonable structure, simple operation, and low assembly and manufacturing cost. Before dispensing, the material carrying tray 50 is placed on the support frame. After flipping the dispensing assembly 40, the top of the dispensing assembly 40 is brought into contact with the material carrying tray by the lifting assembly 70. Then, the material carrying tray 50 is clamped onto the dispensing assembly 40 by the clamping mechanism before subsequent dispensing. Alternatively, the material holding assembly 30 can also be any other structure that can achieve the design purpose.
[0062] The clamping mechanism uses a cylinder chuck structure for gripping, and the material carrier plate has a 3°~5° bevel (the diameter of the material carrier plate is smaller at the bottom and larger at the top), which makes it less likely for the material carrier plate to fall off after being gripped.
[0063] Example 4
[0064] This embodiment is a further optimization based on any one of the embodiments 1 to 3, specifically:
[0065] The material distribution bin 42 includes four symmetrically arranged material distribution funnels. The material distribution combination plate includes a "cross" shaped plate, which overlaps with the top edge of the four material distribution funnels. The "cross" shaped plate extends out of the upper edge of the material distribution cavity 41.
[0066] In this embodiment, a shape and arrangement of the material distribution bin 42 are disclosed, as well as a shape and specific location of the material distribution assembly plate. This scheme utilizes the principle of the quartering method, randomly pouring a portion of material into the material carrying tray 50, and using the mutually perpendicular dividing pieces in the "cross" shaped plate to completely divide the material in the material carrying tray 50 into four portions, sending the four portions of material to the back-end processing, analyzing and measuring the bulk density.
[0067] The "cross" shaped plate is made of polytetrafluoroethylene (PTFE), a material that is anti-static, reduces friction, and provides safety protection.
[0068] Example 5
[0069] This embodiment is a further optimization based on embodiment 2, specifically:
[0070] The feeding mechanism 43 includes a mounting plate, multiple discharge cylinders mounted on the mounting plate, and a feeding control component that controls the synchronous discharge of all discharge cylinders. The mounting plate is fixedly installed at the discharge port of the distribution bin 42, and the number of discharge cylinders is the same as that of the distribution bin 42 and they correspond one-to-one.
[0071] Each material discharge control component includes a control box 431, a draw plate 432, and a first drive mechanism 433. The control box 431 is located below the mounting plate. The upper part of the control box 431 is connected to the discharge port of the corresponding material distribution bin 42, and the lower part of the control box 431 is connected to the corresponding discharge cylinder. A sliding plate outlet is opened on one side of the control box 431. The draw plate 432 is slidably inserted into the control box 431 through the sliding plate outlet. The first drive mechanism 433 controls the reciprocating motion of the draw plate 432 to realize the opening and closing of the corresponding discharge cylinder.
[0072] This embodiment introduces a preferred structure of the feeding mechanism 43, which has the advantages of reasonable structure, simple operation, and low assembly and manufacturing cost. During operation, materials enter the corresponding discharge cylinders of the feeding mechanism 43 from the discharge ports of the distribution bin 42. The feeding mechanism 43 controls whether the corresponding discharge cylinder discharges material. Alternatively, the feeding mechanism 43 can also be other structures that can achieve the design purpose.
[0073] The paper also introduces a preferred structure for the feeding control component, which has the advantages of reasonable structure, simple operation, and low assembly and manufacturing costs. Furthermore, this feeding control component can also be any other structure that achieves the design objective. Specifically, the first drive mechanism 433 in this solution is selected as a drive cylinder, with the cylinder body fixed below the mounting plate, and the piston end of the cylinder corresponding to the slide outlet. The draw plate 432 is made of polytetrafluoroethylene (PTFE) to reduce frictional resistance.
[0074] Example 6
[0075] This embodiment is a further optimization based on embodiment 5, specifically:
[0076] The draw plate 432 is located outside the slide plate outlet. The first drive mechanism 433 is connected to the draw plate 432 located outside the slide plate outlet. The first drive mechanism 433 is fixed on the mounting plate. The fit between the slide plate outlet and the draw plate 432 is a clearance fit, and the width of the clearance is smaller than the particle size of the material.
[0077] In this embodiment, the connection form and positional relationship between the draw plate 432 and the first drive mechanism 433 are specifically described. In addition, the size of the draw plate 432 needs to be larger than the size of the discharge cylinder. This size design can effectively realize the opening and closing of the discharge cylinder and avoid incomplete opening and closing of the discharge cylinder. The width of the gap between the slide outlet and the draw plate 432 is smaller than the particle size of the material. The purpose of this design is to prevent the draw plate 432 from carrying out the material in the control box 431 when it enters and exits, thus avoiding material waste.
[0078] Example 7
[0079] This embodiment is a further optimization based on any one of the embodiments 1-6, specifically:
[0080] Furthermore, the material handling component 20 includes a movable base 22, a plurality of material cups 23 disposed on the movable base 22, and a translational pushing mechanism 21 that drives the movable base 22 to move. The number of material cups 23 is the same as the number of discharge ports of the material dispensing component 40, and the movable base 22 can extend to the bottom of the material holding component 30.
[0081] In this embodiment, the movable base 22 can extend directly below the support frame of the material holding assembly 30. The movable base 22 drives multiple material cups 23 to be located directly below the support frame. When the material carrying tray 50 of the material holding assembly 30 is taken away by the material distributing assembly 40, there is no need to move the position of the material distributing assembly 40. It is only necessary to flip it to realize the loading and unloading of the material distributing assembly 40. This position arrangement can improve work efficiency. After the material distributing assembly 40 finishes discharging, the translation and pushing mechanism 21 retracts, and at the same time, it drives the movable base 22 and the multiple material cups 23 on it to move out of the support frame, which is convenient for subsequent material bulk density testing.
[0082] In addition, the translation and pushing mechanism 21 is one of the translation cylinder, translation oil cylinder, translation electric cylinder or translation lead screw that is horizontally set on the support base 10, or it can be other drive mechanisms that can achieve the purpose of linear drive.
[0083] Example 8
[0084] This embodiment is a further optimization based on any one of the embodiments 1-7, specifically:
[0085] The lifting assembly 70 includes a mounting base 72 vertically mounted on the support base 10 and a lifting mechanism 71 mounted on the top of the mounting base 72. The lifting end of the lifting mechanism 71 is fixedly connected to the tilting and unloading assembly 60.
[0086] In this design, the lifting mechanism 71 can be selected from one of the following: lifting cylinder, lifting hydraulic cylinder, lifting electric cylinder, or lifting screw, or other lifting drive mechanism capable of lifting. The installation slot facilitates the installation of the lifting mechanism 71. The mounting base 72 is a U-shaped installation slot formed by three baffles. The tilting and unloading component 60 is located inside the U-shaped installation slot, which can protect the tilting and unloading component 60 during lifting and has a stable lifting effect.
[0087] Example 9
[0088] This embodiment is a further optimization based on any one of the embodiments 1-8, specifically:
[0089] The tilting and unloading assembly 60 includes a rotating component 62 and a rotating drive mechanism 61.
