Description

Technical Field

[0001] This utility model belongs to the technical field of hazardous explosives dismantling equipment, and specifically relates to a landmine cutting machine. Background Technology

[0002] Landmines, as defensive pyrotechnics, are stored in appropriate quantities. However, their safety and reliability decrease after long-term storage, necessitating their disposal. Currently, the traditional disposal method is primarily through explosion. However, this method is not only highly dangerous and environmentally polluting but also hinders resource recycling and reuse, resulting in resource waste. Manual dismantling, on the other hand, allows for resource recovery, typically involving manually cutting the landmines before further dismantling. However, this operation is slow and poses significant safety hazards to personnel. Therefore, it is necessary to develop an automated cutting device to replace manual cutting. Utility Model Content

[0003] To address the above problems, this utility model provides a landmine cutting machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A landmine cutting machine includes a bed and a rotating mechanism, a clamping mechanism, a positioning mechanism, and a cutting mechanism disposed on the bed. The clamping mechanism is disposed on a worktable at the top of the bed and is used to clamp and fix the lower edge of the landmine. The positioning mechanism is disposed above the clamping mechanism and is used to abut against the top of the landmine. The output end of the rotating mechanism is connected to the clamping mechanism and is used to drive the clamping mechanism and the landmine to rotate. The cutting mechanism is disposed on the side of the landmine and is used to cut the shell of the landmine. The rotating mechanism, clamping mechanism, positioning mechanism, and cutting mechanism are all electrically connected to a controller.

[0006] Furthermore, the positioning mechanism includes a lifting component and a positioning plate. The positioning plate is connected to the movable end of the lifting component. The lifting component is mounted on a support frame, and the support frame is connected to the worktable at the top of the bed.

[0007] Furthermore, the lifting component is provided with symmetrical positioning rods on both sides. The upper end of the positioning rod is connected to the fixing plate by positioning screws, and the lower ends of the two fixing rods are connected by a support plate. The fixing shaft of the positioning plate is embedded in the middle of the support plate.

[0008] Furthermore, the feed mechanism includes a telescopic component, a feed holder, and a cutting blade. The movable end of the telescopic component is equipped with a pressure sensor and is connected to the feed holder. The cutting blade is located at the other end of the feed holder and is used to cut the top edge of the landmine. The telescopic component and the feed holder are mounted on a support base on the workbench. The support base has tracks on both sides that slide with the feed holder. The telescopic component is located at the rear of the support base.

[0009] Furthermore, the cutting blade includes a blade holder and two roller cutters. The two roller cutters are symmetrically arranged at both ends of one side edge of the blade holder. The roller cutters are rotatably engaged with the cutter shaft at the corner of the blade holder. The middle part of the other side of the blade holder is rotatably connected to the middle part of the front end of the feed post.

[0010] Furthermore, the cutting mechanism consists of two sets, symmetrically arranged on the worktables on both sides of the landmine.

[0011] Furthermore, the lifting component is a lifting cylinder, and the telescopic component is a telescopic cylinder.

[0012] Furthermore, the clamping mechanism is a clamping cylinder, and the jaws of the clamping cylinder are used to clamp the lower part of the landmine.

[0013] Furthermore, the rotating mechanism includes a rotating shaft and a motor. The motor drives the rotating shaft to rotate through a transmission assembly. The rotating shaft passes through the worktable and is connected to a clamping cylinder.

[0014] Furthermore, the side of the bed is equipped with a control panel connected to the controller, and the bed is connected to the ground via a grounding wire.

[0015] The technological advancements achieved by this invention compared to existing technologies are as follows:

[0016] This invention involves placing a landmine in a clamping mechanism, which is then controlled by a controller to secure the landmine. The controller then controls a positioning mechanism to bring the landmine into contact with its top. Once positioned, a rotating mechanism and a cutting mechanism are activated to automatically cut the landmine's casing. After cutting, the controller raises the positioning mechanism and releases the clamping mechanism, allowing the landmine to be manually removed. This invention replaces manual cutting, offering high efficiency, reducing labor costs, and improving operational safety and reliability. It is suitable for handling landmines in batches.

Detailed Implementation

[0027] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2As shown in the figure, the landmine cutting machine provided in this embodiment of the present invention includes a bed 1 and a rotating mechanism 2, a clamping mechanism 3, a positioning mechanism 4, and a cutting mechanism 5 disposed on the bed 1. The clamping mechanism 3 is disposed on the worktable 7 at the top of the bed 1 and is used to clamp and fix the lower edge of the landmine 00. The positioning mechanism 4 is disposed above the clamping mechanism 3 and is used to abut against the top of the landmine 00. The output end of the rotating mechanism 2 is connected to the clamping mechanism 3 and is used to drive the clamping mechanism 3 and the landmine 00 to rotate. The cutting mechanism 5 is disposed on the landmine 00. The side of the bed 1 is used to cut the shell of the landmine 00; the rotating mechanism 2, clamping mechanism 3, positioning mechanism 4 and feed mechanism 5 are all electrically connected to the controller (not shown in the figure, which can be placed inside the bed under the worktable). At the same time, a control panel (not shown in the figure) connected to the controller is provided on the side of the bed 1, which is convenient for the operator to input operating parameters. The control panel can automatically cut after the equipment is controlled by the PLC; the bed 1 is connected to the ground through a grounding wire (not shown in the figure) to ensure reliable grounding of the bed and further improve safety performance.

[0029] The clamping mechanism secures the landmine, and after positioning the landmine using a positioning mechanism, the rotating and cutting mechanisms are activated. These two mechanisms work together to automatically cut the landmine casing. After cutting, the controller raises the positioning mechanism and releases the clamping mechanism, allowing the landmine to be manually removed. This landmine cutting machine is suitable for cutting various types of iron-cased and plastic-cased landmines.

[0030] As a preferred structure, such as Figure 2 , 3 As shown, the positioning mechanism 4 includes a lifting component 41 and a positioning plate 42. The positioning plate 42 is connected to the movable end of the lifting component 41. The lifting component 41 is mounted on a support frame 6, which is connected to the worktable 7 at the top of the bed 1. The lifting component 41 has symmetrically arranged positioning rods 43 on both sides. The upper ends of the positioning rods 43 are connected to a fixed plate 45 via positioning screws 44. The lower ends of the two fixed rods 45 are connected via a support plate 46. The fixed shaft of the positioning plate 42 is embedded in the middle of the support plate 46. The lifting component can be a lifting cylinder. A controller controls the lifting cylinder to raise and lower the positioning plate. When the positioning plate approaches the surface of the landmine, the positioning rods are finely adjusted via the positioning screws to ensure the positioning plate abuts against the landmine, ensuring that the positioning plate does not press against the landmine but only provides support for the top of the landmine.

[0031] In specific embodiments of this utility model, such as Figure 4 , 5As shown, the cutting mechanism 5 includes a telescopic component 51, a cutting post 52, and a cutting blade 53. The movable end of the telescopic component 51 is equipped with a pressure sensor 50 and is connected to the cutting post 52. The cutting blade 53 is located at the other end of the cutting post 52 and is used to cut the top edge of the landmine 00. The telescopic component 51 and the cutting post 52 are mounted on a support base 8 on the workbench 7. The support base 8 has rails 9 on both sides that slide with the cutting post 52. The telescopic component 51 is located at the tail of the support base 8. In specific manufacturing, the cutting blade 53 includes a blade holder 531 and two roller cutters 532. The two roller cutters 532 are symmetrically arranged at both ends of one edge of the blade holder 531. The roller cutters 532 rotate with the cutter shaft at the corner of the blade holder 531. The middle of the other side of the blade holder 531 is rotatably connected to a mounting bracket at the front end of the cutting post 52. The mounting bracket is connected to the cutting post via a height adjustment bolt 11, and the end of the mounting bracket has an elongated hole that mates with the height adjustment bolt. After the landmine 00 is fixed on the clamping mechanism 3, loosen the height adjustment bolt 11 to adjust the height of the mounting bracket and the cutting blade 53, so that the roller blade 532 is aligned with the edge of the cutting section 10 on the landmine 00, and then lock the mounting bracket to fix it. A test cut can be performed first. When the roller blade touches the landmine, the pressure sensor 50 displays an increased pressure value. When the roller blade cuts through the landmine, the pressure sensor's pressure value decreases, the landmine is cut, the roller blade retracts, and the adjustment is complete.

[0032] Further optimize the above structure, such as Figure 5 As shown, the cutting mechanism 5 consists of two sets, symmetrically arranged on the worktables 7 on both sides of the landmine 00. Using two sets of cutting mechanisms allows for rapid cutting of the landmine while ensuring balanced force distribution on both sides of the mine.

[0033] In specific manufacturing, the telescopic component 51 is a telescopic cylinder; simultaneously, the clamping mechanism 3 is a clamping cylinder (i.e., a pneumatic gripper), and the jaws 30 of the clamping cylinder are used to clamp the lower part of the landmine 00. Automatic cutting operation is achieved by controlling the movements of the telescopic cylinder and the clamping cylinder through a controller.

[0034] In specific design, such as Figure 2 As shown, the rotating mechanism 2 includes a rotating shaft 21 and a motor 22. The motor 22 drives the rotating shaft 21 to rotate through a transmission assembly. The rotating shaft 21 passes through the worktable 7 and is connected to the clamping cylinder. The transmission assembly can be a gear drive or a belt drive, which is existing technology and will not be described again.

[0035] like Figure 6 As shown, the specific application process of this utility model is as follows:

[0036] a. After starting the automatic program on the control panel, place the landmine in the jaw position of the clamping cylinder, release the landmine with both hands, and press the start button on the control panel to start the device.

[0037] b. The clamping cylinder clamps the landmine, and the positioning plate descends into place.

[0038] c. The motor drives the rotating shaft and the landmine to start rotating. The telescopic cylinder pushes the roller cutter forward. The telescopic cylinder maintains air supply. The roller cutter begins to cut the landmine. When the pressure sensor pressure decreases, the roller cutter cuts the landmine open. The roller cutter retracts, and the clamping cylinder stops rotating.

[0039] d. The positioning plate retracts, and the clamping cylinder releases the landmine.

[0040] e. Manually remove the cut landmine, being careful of the burrs on its outer surface that could cut your hands. Be careful not to let it slip, as this could trigger the program and cause malfunctions.

[0041] This completes one cycle of mine cutting.

[0042] After finishing work, first press the "Stop" button on the control panel, then turn off the switch of the controller inside the workbench. Finally, turn off the AC power switch. Clean up the work area, remove the explosives, wipe the bed, and apply oil to the rails. Cover with the dust cover.

[0043] In summary, the mine cutting machine provided by this utility model adopts a vertical structure and can perform the cutting of various iron-cased and plastic-cased mines. The equipment has a reasonable process layout, a high degree of automation, simple operation, good reliability and safety, high operating efficiency, significant economic benefits, small size and light weight, and is especially suitable for batch cutting and disposal of mines.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
