There are at least two clamping jaws 436, and multiple clamping jaws 436 correspond one-to-one to multiple racks 434. The clamping jaws 436 are connected to the corresponding racks 434 and are located outside the support base 431, so that when the racks 434 move, the clamping jaws 436 can simultaneously move in the direction of approaching or away from the gear 433 to complete the clamping and releasing actions of the mechanical claw 43.

[0063] like Figure 2 and Figure 6 As shown, the mechanical claw 43 also includes a second sensing switch 437, which is connected to the support base 431, and the triggering portion of the second sensing switch 437 is located below the support base 431. The second sensing switch 437 is used to detect whether the mechanical claw 43 is in contact with and separated from the cover. When clamping the cover, when the second sensing switch 437 senses that the mechanical claw 43 is in contact with the cover, the second sensing switch 437 sends a signal to the control system, and the control system controls the mechanical claw 43 to stop moving and clamp the cover.

[0065] like Figures 2 to 4As shown, specifically, the barrel delivery assembly 5 includes a second fixed frame 51 and a plurality of second rollers 52, and the second fixed frame 51 is located on the second side of the main support 1 (such as Figure 3 The second support frame 51 is connected to the second support frame 51 and is spaced apart along the length direction of the second support frame 51, so that the sample collecting bucket can be smoothly moved along the length direction of the second support frame 51. The second support frames 52 are used to support and transport the sample collecting bucket. The second support frames 52 are driven by one or more chains at the same time to prevent the sample collecting bucket from tipping over or failing to move to the set position normally due to inconsistent rotation speeds of the second support frames 52.

[0066] The barrel pushing assembly 6 is connected to the main support 1 and is used to push the sample collecting barrel from the barrel inlet conveying assembly 3 to the barrel outlet conveying assembly 5 .

[0067] like Figure 3 , Fig. 9 and Fig.10 As shown, specifically, the barrel pushing assembly 6 includes a third slide 61, a barrel pushing arm 62 and a positioning baffle 63. The third slide 61 is connected to the main bracket 1, one end of the barrel pushing arm 62 is connected to the slider of the third slide 61, so that the barrel pushing arm 62 can move along the length direction of the third slide 61 with the slider of the third slide 61, the other end of the barrel pushing arm 62 is used to push the sample collecting barrel, and the other end of the barrel pushing arm 62 is installed with an arc plate matching the sample collecting barrel to ensure the stability of the barrel pushing arm 62 when pushing the sample collecting barrel; the positioning baffle 63 is connected to the base of the third slide 61, and the positioning baffle 63 is provided with a limiting groove for limiting the moving range of the barrel pushing arm 62, so as to ensure that the barrel pushing arm 62 stops accurately at a predetermined position to avoid damage or misoperation caused by excessive movement.

[0068] When the present invention is used, after the main support 1 and the lid placing rack 22 are assembled, the staff manually or by machine places the sample collecting barrel on the barrel feeding conveying assembly 3, and the barrel feeding conveying assembly 3 transports the sample collecting barrel to the set position in the main support 1 for sample collection; after the sample collection is completed, the sliding frame 42 drives the mechanical claw 43 to move to the top of the lid placing rack 22, and then the second slide 422 drives the mechanical claw 43 to move downward until the mechanical claw 43 contacts the lid, and the driving member 432 drives the gear 433 to rotate forward, and the gear 433 drives the clamping claw 436 to move in the direction close to the gear 433 through the rack 434, so as to complete the The pairs of lids are clamped; then the sliding frame 42 drives the mechanical claw 43 to move to the top of the sample collecting barrel, and the second slide 422 drives the mechanical claw 43 to move downward until the first sensor switch 424 detects that the mechanical claw 43 has moved to the set position; the driving member 432 drives the gear 433 to rotate in the opposite direction, and the gear 433 drives the clamping claw 436 to move in the direction of the principle gear 433 through the rack 434 to complete the installation of the lid and complete the separation of the mechanical claw 43 and the lid; then the mechanical claw 43 is reset, and at the same time, the barrel pushing assembly 6 transports the covered and locked sample collecting barrel to the recovery position, completing a cycle.

[0069] The automatic in-and-out bucket device of the coal sampler in the embodiment of the present invention realizes functions such as automatic in-and-out, automatic lid placement and automatic transportation of the sample collection bucket through automatic control, which greatly improves sampling efficiency and accuracy and reduces labor costs and safety risks.

[0070] like Figure 2 As shown, in some embodiments, the coal sampler automatic entry and exit barrel device also includes a third induction switch 7 and a fourth induction switch 8.

[0071] The third induction switch 7 is connected to the main bracket 1. The third induction switch 7 is used to detect whether the sample collecting bucket has reached the specified position (for example, when the sample collecting bucket contacts the third induction switch 7, the third induction switch 7 will send a signal, indicating that the sample collecting bucket is ready for sampling). The type of the third induction switch 7 can be selected according to actual needs, such as a photoelectric switch, a proximity switch, etc., to ensure that the position of the sample collecting bucket can be accurately and reliably detected.

[0072] The fourth induction switch 8 is connected to the first fixed body and is used to detect whether a sample barrel passes by. When the sample barrel moves on the barrel feeding conveying assembly 3 and passes through the fourth induction switch 8, the switch will send a signal, indicating that a sample barrel is entering the sampling area. The fourth induction switch 8 can also select a suitable type according to actual needs, such as a photoelectric switch, a magnetic induction switch, etc., to ensure that the presence of the sample barrel can be accurately and timely detected.

[0073] During the operation of the device, when the third sensing switch 7 senses that a sample barrel has arrived at the designated position, the control system will receive the signal and prepare to perform sampling operations. At the same time, the fourth sensing switch 8 continues to monitor the status of the sample barrel on the barrel feed conveying assembly 3; when the third sensing switch 7 senses that a sample barrel has arrived at the designated position and the fourth sensing switch 8 detects that a sample barrel has passed, the barrel feed conveying assembly 3 stops working to prevent multiple sample barrels from entering the main bracket 1 at the same time, thereby improving the safety and sampling efficiency of the device.

[0074] Therefore, the automatic in-and-out bucket device of the coal sampler in the embodiment of the present invention realizes the precise detection of the position of the sample bucket and the intelligent control of the conveying component by adding the third induction switch 7 and the fourth induction switch 8, which not only improves the automation level and safety of the sampling process, but also helps to reduce human intervention and misoperation.
