[0033] The embodiment of the present invention provides a lid opening and discharging machine, which can be used for the lid opening and discharging operations of coal samples or other sample material containers, wherein the lid opening and discharging machine includes: an opening and closing lid assembly 4, a discharging assembly 3, and a driving assembly. In specific applications, the lid opening and discharging machine also includes a discharging assembly frame 5 and an opening and closing lid assembly frame 6, wherein the discharging assembly 3 and the driving assembly are installed on the discharging assembly frame 5, and the opening and closing lid assembly 4 is installed on the opening and closing lid assembly frame 6. The above two frames mainly play a bearing role, and their specific structures can be selected according to actual conditions. This embodiment does not make specific restrictions on this. The discharging assembly 3 includes a manipulator and a flip assembly. In addition, in order to achieve the degree of automation of the lid opening and discharging machine, it also includes an incoming material photoelectric sensor, a magnetic induction switch and a proximity switch 20 and a controller, wherein the magnetic induction switch and the proximity switch 20 are arranged on the manipulator. When the material barrel transported by the roller line reaches the preset designated position, When the material is in the position, it will be detected by the incoming material photoelectric sensor and send a signal to the controller. The controller then controls the drive assembly to drive the unloading assembly 3 to move downward from the origin position, and at the same time start the manipulator to open into place. In order to ensure that the manipulator is opened into place, the magnetic induction switch on the manipulator driving cylinder and the proximity switch 20 simultaneously detect the material barrel to determine. When the manipulator descends to the preset position, the manipulator clamps the material barrel, and then the drive assembly drives the manipulator to move to the opening and closing cover assembly 4. The opening and closing cover assembly 4 starts the opening action, and then the drive assembly drives the manipulator to move to the unloading position for unloading. After the unloading operation is completed, the drive assembly drives the manipulator to move to the opening and closing cover assembly 4 for closing the cover. Finally, the drive assembly transports the material barrel to the specified position of the roller line, and then releases the manipulator to let the material barrel detach, and then feeds the manipulator to the paper origin position to continue the operation of the next material barrel. Compared with the traditional storage method with separate barrels and lids, this application can realize the functions of conveying material barrels with lids and returning empty barrels through the driving component and the opening and closing lid component 4, and can convey the material barrels with lids to the sampling end, and can realize unmanned operation of the entire process.

[0034] The opening and closing lid assembly 4 is preferably an electromagnet-type opening and closing lid assembly 4, which utilizes electromagnet suction to open the lid. Since coal sample barrels with password covers are commonly used, when opening the lid, a controller sends an opening signal to the password cover, simultaneously supplies 12V weak power to the password cover, and supplies 24V weak power to the battery-type opening and closing lid assembly 4 to initiate the opening operation. When closing the lid, the password cover is snapped onto the coal sample barrel.

[0035] Specifically, the electromagnetic opening and closing cover assembly 4 includes an opening and closing cover support 27, an opening and closing cover electromagnet 28, a guide rod 24 and a telescopic spring 30. The opening and closing cover support 27 is fixedly connected to the opening and closing cover assembly frame 6, and the upper end of the guide rod 24 is connected to the opening and closing cover support 27, wherein the guide rod 24 can be installed on the opening and closing cover support 27 through a linear bearing seat 23, and the opening and closing cover electromagnet 28 is slidably sleeved on the lower end of the guide rod 24. The telescopic spring 30 is sleeved on the guide rod 24, and its two ends are respectively pressed against the opening and closing cover support 27 and the opening and closing cover electromagnet 28. Due to the telescopic spring 30, the opening and closing cover electromagnet 28 can have a slight adjustment margin in the vertical direction, thereby ensuring that the opening and closing cover electromagnet 28 can contact the password cover.

[0036] In addition, the lid opening and closing assembly 4 is provided with a lid opening and closing proximity switch 29, which is used to detect whether a lid is attracted to the lid opening and closing electromagnet 28. When the controller sends a lid opening signal to the lid opening and closing assembly 4, the lid opening and closing proximity switch 29 first detects whether a lid is already in the opening position. If so, an alarm is triggered and the lid opening action is canceled. If not, the lid opening action is not executed. At the same time, the lid opening and closing proximity switch 29 is also used to determine whether the password cover has fallen off due to an unexpected power outage or other unexpected circumstances after the lid is opened, thereby preventing damage to related components caused by malfunction.

[0037] Specifically, the driving assembly includes a lifting assembly 2 and a horizontal moving assembly 1. The lifting assembly 2 is connected to the material discharge assembly 3 and is used to drive the material discharge assembly 3 to move. The horizontal moving assembly 1 is used to drive the lifting assembly 2 to move horizontally, that is, the material barrel can move in the vertical plane. The horizontal moving assembly 1 includes a horizontal linear guide 9, a horizontal drive motor 10, a horizontal synchronous pulley 7, a horizontal synchronous belt 8 and a mounting seat 12. The horizontal synchronous pulley 7 can be installed on the horizontal linear guide 9 through a horizontal linear bearing 11. The mounting seat 12 is installed on the horizontal synchronous belt 8 and is slidably connected to the horizontal linear guide 9. It mainly plays the role of carrying the lifting assembly 2. The horizontal drive motor 10 is used to drive the horizontal synchronous belt 8 to rotate and then drive the mounting seat 12 to move along the horizontal linear guide 9. It should be noted that the above-mentioned horizontal moving assembly 1 is only a preferred synchronous belt transmission mechanism. In addition, other linear displacement drive components such as cylinders or linear motors can also be selected.

[0038] Specifically, the lifting assembly 2 includes a lifting linear guide 17, a lifting rack 16, a lifting gear 15, and a lifting drive motor 14. The lifting linear guide 17 is mounted on the fixed base 13, the lifting drive motor 14 and the lifting gear 15 are arranged on the material discharging assembly 3, the lifting rack 16 is vertically arranged on the lifting linear guide 17, the material discharging assembly 3 is slidably connected to the lifting linear guide 17, the lifting gear 15 and the lifting rack 16 are meshed with each other, and the lifting drive motor 14 is used to drive the lifting gear 15 to rotate, thereby driving the material discharging assembly 3 to rise and fall on the lifting rack 16. It should be noted that the gear rack is only a preferred transmission method. In addition, other driving methods can also be used, such as a cylinder or a linear motor, as long as the lifting and falling of the material discharging assembly 3 can be achieved.

[0039] Furthermore, the manipulator is provided with a vibrator 26, which is used to vibrate the material barrel to shake off the residual material in the material barrel.

[0040] Specifically, the flipping assembly includes a rotary drive motor 18 and a synchronous belt transmission component. The rotary drive motor 18 is used to drive the manipulator to rotate through the synchronous belt transmission component, wherein the synchronous belt transmission component includes an active rotary synchronous pulley 19 and a passive rotary synchronous pulley 21. The passive rotary synchronous pulley 21 is fixedly connected to the manipulator. The rotary drive motor 18 drives the active rotary synchronous pulley 19 to rotate, thereby driving the passive rotary synchronous pulley 21 and the manipulator to rotate.

[0041] Specifically, the manipulator includes a fixed base 13, a guide rod 24, two clamping plates, and a telescopic drive unit. A passive rotary synchronous pulley 21 is fixed to the fixed base 13. The guide rod 24 is laterally fixed to the fixed base 13 and can be mounted on the fixed base 13 via a linear bearing 23. The two clamping plates are slidably connected to the guide rod 24. When the material barrel needs to be clamped, the two clamping plates are driven toward each other by the telescopic drive unit. When the material barrel needs to be loosened, the two clamping plates are driven away from each other. The telescopic drive unit can be a barrel clamping cylinder 25 or a linear screw drive component. In addition, a spring 22 can be mounted on the guide rod 24, and the ends of the spring 22 respectively press against the portions of the two clamping plates that are sleeved on the guide rod 24. Furthermore, the opposing surfaces of the two clamping plates are curved, which can contact the outer wall of the material barrel, thereby ensuring the clamping stability of the material barrel.

[0042] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
