[0051] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0052] The following combines the attached Figures 1 to 12 Describe the automatic barrel-in and barrel-out device of the coal sampler in the embodiments of the present invention.

[0053] As Figures 1 to 12 As shown, the automatic barrel-in and barrel-out device of the coal sampler in the embodiments of the present invention includes a main bracket 1, a lid-putting rack 22, a barrel-in conveying assembly 3, a lid-putting assembly 4, a barrel-out conveying assembly 5 and a barrel-pushing assembly 6. Among them:

[0054] The main bracket 1 is composed of multiple steel pipes cut diagonally and welded, and is used to support and fix other components. Its shape and size can be designed according to actual needs to ensure the stability and reliability of the device.

[0055] The lid-putting rack 22 is used to store the lids of the sampling buckets and facilitate the mechanical claw 43 to grab. The lid-putting rack 22 is detachably connected to the main bracket 1 by bolts, buckles, wire bundling or other means to prevent relative movement between the lid-putting rack 22 and the main bracket 1, resulting in the mechanical claw 43 being unable to normally grab the lids of the sampling buckets.

[0056] The barrel-in conveying assembly 3 is connected to the main bracket 1, and the barrel-in conveying assembly 3 is used to convey the sampling bucket into the main bracket 1.

[0057] As Figures 2 to 4 As shown, specifically, the barrel-in conveying assembly 3 includes a first fixing bracket 31 and multiple first idlers 32. The first fixing bracket 31 is located on the first side of the main bracket 1 (such as Figure 3is fixed to the ground at the rear side as shown, and a plurality of first rollers 32 are all connected to the first fixing frame 31 and are spaced along the length direction of the first fixing frame 31, so that the sample collecting bucket can smoothly move along the length direction of the first fixing frame 31. The plurality of first rollers 32 are used to support and convey the sample collecting bucket, and the plurality of first rollers 32 are all driven by one or more chains simultaneously, so as to avoid the sample collecting bucket from tipping over or failing to move to the set position normally due to inconsistent rotation speeds of the first rollers 32.

[0058] The cover placing assembly 4 includes a cross beam 41, a sliding frame 42 and a mechanical claw 43. There are a plurality of cross beams 41, and the plurality of cross beams 41 are all connected inside the main bracket 1 and are spaced along the vertical direction. The length direction of the cross beam 41 is arranged along a first direction (such as Figure 1 the left - right direction as shown), and the first direction is orthogonal to the vertical direction. The sliding frame 42 is connected to the cross beam 41 and can move along the length direction of the cross beam 41. The mechanical claw 43 is connected to the sliding frame 42 and can move along the vertical direction on the sliding frame 42. The mechanical claw 43 is designed to be able to grab the lid on the lid placing frame 22 and place and fix it on the sample collecting bucket.

[0059] As Figure 1 and Figure 2 shown, specifically, the sliding frame 42 includes a first sliding table 421, a second sliding table 422 and a connecting piece 423. The first sliding table 421 is connected to one of the cross beams 41, and the length direction of the first sliding table 421 is arranged along the length direction of the cross beam 41. The second sliding table 422 is connected to the slider of the first sliding table 421, so that the whole second sliding table 422 can move along the length direction of the first sliding table 421 along with the slider of the first sliding table 421. Moreover, the second sliding table 422 is slidably connected to a plurality of cross beams 41 respectively to ensure the stability of the second sliding table 422 when it moves. The length direction of the second sliding table 422 is arranged along the vertical direction. The connecting piece 423 is connected to the slider of the second sliding table 422 and is provided with a positioning groove 4231 matching the mechanical claw 43. The mechanical claw 43 is detachably connected to the connecting piece 423, and a part of the mechanical claw 43 is located in the positioning groove 4231 to facilitate the positioning of the mechanical claw 43. Through the first sliding table 421 and the second sliding table 422, the mechanical claw 43 can move in the vertical direction and the horizontal direction, so as to facilitate the mechanical claw 43 to complete the grasping and placing of the lid.

[0060] It should be noted that the first sliding table 421, the second sliding table 422 (and the following third sliding table 61) in the embodiments of the present invention are all commonly used sliding tables in the art, which include a base, a guide rail, a slider, a driving system and other auxiliary components. Their specific structural compositions and operating principles are all commonly used in the art and will not be elaborated here.

[0061] As Figure 2As shown, further, the sliding carriage 42 further includes a first induction switch 424. The first induction switch 424 is connected to the base of the second slide 422. The first induction switch 424 is used to detect whether the mechanical claw 43 has moved to a set position. When the mechanical claw 43 moves to the set position, the first induction switch 424 sends a signal to the control system, and the control system controls the mechanical claw 43 to stop moving and installs the lid on the sample collecting bucket.

[0062] As Figure 1 , Figure 2 , Figures 5 to 7 As shown, specifically, the mechanical claw 43 includes a support base 431, a driving member 432, a gear 433, a rack 434, a limiting member 435, and a clamping jaw 436. The support base 431 is connected to the sliding carriage 42. The driving member 432 (such as a motor) is connected to the support base 431 and is located above the support base 431. The gear 433 is sleeved on the output shaft of the driving member 432. The driving member 432 is used to drive the gear 433 to rotate. There are at least two racks 434. The multiple racks 434 are all connected to the inside of the support base 431 and mesh with the gear 433. The multiple racks 434 are spaced apart along the circumference of the gear 433 so that the multiple racks 434 move in different directions respectively. There are at least two limiting members 435. The multiple limiting members 435 are all connected to the inside of the support base 431, and the multiple limiting members 435 correspond to the multiple racks 434 one by one. The limiting member 435 is used to limit the moving range of the corresponding rack 434 to prevent the mechanical claw 43 (and the clamping jaw 436) from moving excessively. There are at least two clamping jaws 436. The multiple clamping jaws 436 correspond to the multiple racks 434 one by one. The clamping jaw 436 is connected to the corresponding rack 434 and is located outside the support base 431. When the rack 434 moves, the clamping jaw 436 can move towards or away from the gear 433 at the same time to complete the actions of clamping and releasing of the mechanical claw 43.

[0063] As Figure 2 and Figure 6 As shown, the mechanical claw 43 further includes a second induction switch 437. The second induction switch 437 is connected to the support base 431, and the triggering part of the second induction switch 437 is located below the support base 431. The second induction switch 437 is used to detect whether the mechanical claw 43 contacts and separates from the lid. When clamping the lid, when the second induction switch 437 senses that the mechanical claw 43 contacts the lid, the second induction switch 437 sends a signal to the control system, and the control system controls the mechanical claw 43 to stop moving and clamp the lid.

[0064] The out - bucket conveying assembly 5 is connected to the main bracket 1. The out - bucket conveying assembly 5 is used to convey the sample collecting bucket with the lid installed and locked to the recycling position.

[0065] As Figures 2 to 4As shown, specifically, the out-barrel conveying assembly 5 includes a second fixing frame 51 and a plurality of second rollers 52. The second fixing frame 51 is located on the second side of the main support 1 (such as Figure 3 the right side shown) and is fixedly installed on the ground. The plurality of second rollers 52 are all connected to the second fixing frame 51 and are spaced along the length direction of the second fixing frame 51, so that the sampling bucket can smoothly move along the length direction of the second fixing frame 51. The plurality of second rollers 52 are used to support and convey the sampling bucket. The plurality of second rollers 52 are all driven by one or more chains simultaneously, avoiding the sampling bucket from tipping over or failing to move to the set position normally due to inconsistent rotation speeds of the second rollers 52.

[0066] The barrel-pushing assembly 6 is connected to the main support 1. The barrel-pushing assembly 6 is used to push the sampling bucket from the in-barrel conveying assembly 3 onto the out-barrel conveying assembly 5.

[0067] As Figure 3 , Figure 9 and Figure 10 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 support 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 sampling bucket, and an arc-shaped plate matching the sampling bucket is installed at the other end of the barrel-pushing arm 62 to ensure the stability when the barrel-pushing arm 62 pushes the sampling bucket; the positioning baffle 63 is connected to the base of the third slide 61, and a limit groove for restricting the moving range of the barrel-pushing arm 62 is provided on the positioning baffle 63, so as to ensure that the barrel-pushing arm 62 stops accurately at a predetermined position and avoid damage or misoperation caused by excessive movement.

[0068] When the present invention is in use, after the main bracket 1 and the cover placing bracket 22 are assembled, the staff manually or uses a machine to place the sampling bucket on the bucket feeding assembly 3. The bucket feeding assembly 3 transports the sampling bucket to a set position inside the main bracket 1 and then performs sampling. After sampling is completed, the sliding bracket 42 drives the mechanical claw 43 to move directly above the cover placing bracket 22. Subsequently, the second sliding table 422 drives the mechanical claw 43 to move downward until the mechanical claw 43 contacts the cover. The driving member 432 drives the gear 433 to rotate forward. The gear 433 drives the clamping jaw 436 to move towards the direction close to the gear 433 through the rack 434 to complete the clamping of the cover. Subsequently, the sliding bracket 42 drives the mechanical claw 43 to move directly above the sampling bucket, and the second sliding table 422 drives the mechanical claw 43 to move downward until the first induction 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 reverse direction. The gear 433 drives the clamping jaw 436 to move away from the gear 433 through the rack 434 to complete the installation of the cover and separate the mechanical claw 43 from the cover. Subsequently, the mechanical claw 43 resets. At the same time, the bucket pushing assembly 6 transports the sampled bucket with the cover installed and locked to the recycling position to complete one cycle.

[0069] The automatic bucket inlet and outlet device of the coal sampler according to the embodiment of the present invention realizes functions such as automatic inlet and outlet of the sampling bucket, automatic cover placement, and automatic transportation through automatic control, greatly improving the sampling efficiency and accuracy, and reducing the labor cost and safety risk.

[0070] As Figure 2 shown, in some embodiments, the automatic bucket inlet and outlet device of the coal sampler further includes a third induction switch 7 and a fourth induction switch 8.

[0071] The third induction switch 7 is connected inside the main bracket 1. The third induction switch 7 is used to detect whether the sampling bucket reaches the specified position (for example, when the sampling bucket contacts the third induction switch 7, the third induction switch 7 will send a signal indicating that the sampling 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 sampling bucket can be accurately and reliably detected.

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

[0073] During the operation of the device, when the third induction switch 7 senses that a sample collection bucket reaches the designated position, the control system will receive this signal and prepare for the sampling operation. At the same time, the fourth induction switch 8 continuously monitors the situation of the sample collection bucket on the incoming bucket conveying assembly 3; when the third induction switch 7 senses that a sample collection bucket reaches the designated position and the fourth induction switch 8 detects that a sample collection bucket passes by, the incoming bucket conveying assembly 3 stops working to prevent multiple sample collection buckets from entering the main bracket 1 simultaneously, improving the safety and sampling efficiency of the device.

[0074] Thus, the automatic in-and-out bucket device of the coal sampler according to the embodiment of the present invention realizes precise detection of the position of the sample collection bucket and intelligent control of the conveying assembly 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.

[0075] As Figure 3 shown, optionally, the length direction of the first fixing frame 31 is arranged along the second direction (such as the front-back direction shown in Figure 3 ), the second direction is orthogonal to the up-down direction, and the length direction of the second fixing frame 51 is arranged along the third direction (such as the left-right direction shown in Figure 3 ). This orthogonal layout enables the incoming bucket conveying assembly 3 and the outgoing bucket conveying assembly 5 to be arranged in different directions, thereby increasing the flexibility of the device layout.

[0076] As Figure 4 shown, optionally, the first fixing frame 31 and the second fixing frame 51 are spaced apart along the second direction (such as the left-right direction shown in Figure 4 ), and the length directions of both the first fixing frame 31 and the second fixing frame 51 are arranged along the third direction (such as the front-back direction shown in Figure 4 ). This parallel layout is suitable for sampling sites with limited space or requiring a compact layout. By arranging the incoming bucket conveying assembly 3 and the outgoing bucket conveying assembly 5 in parallel, the floor area of the device in the horizontal direction can be minimized while maintaining a smooth and efficient conveying path.

[0077] Thus, the automatic in-and-out bucket device of the coal sampler according to the embodiment of the present invention can be flexibly arranged according to the specific conditions of the sampling site, such as the space size, the requirements of the conveying path, and the coordination with other equipment, increasing the flexibility and adaptability of the device.

[0078] As Figure 3 and Figure 9As shown, in some embodiments, the automatic in-and-out barrel device of the coal sampler further includes a plurality of idler rollers 9. The plurality of idler rollers 9 are all installed in the main bracket 1, and the plurality of idler rollers 9 are all located between the in-barrel conveying assembly 3 and the out-barrel conveying assembly 5. The idler rollers 9 are used to assist in supporting and guiding the sampling bucket, reducing the wear on the sampling bucket and the equipment when the bucket-pushing assembly 6 pushes the sampling bucket, and ensuring that the sampling bucket can move smoothly and smoothly during the conveying process.

[0079] As Figure 11 and Figure 12 As shown, in some embodiments, the main bracket 1 is provided with a positioning member 11, and the cover placing frame 22 is provided with a positioning hole matching the positioning member 11. When the cover placing frame 22 needs to be installed on the main bracket 1, only by aligning the positioning hole with the positioning member 11 and inserting it, the quick and accurate positioning of the cover placing frame 22 can be realized, which not only improves the stability and accuracy of the installation of the cover placing frame 22, but also helps to reduce the installation time and cost.

[0080] As Figure 1 and Figure 2 As shown, in some embodiments, the bottom of the main bracket 1 is provided with a plurality of fixed supports 12 to firmly fix the main bracket 1 at a set position, and the bottom of the cover placing frame 22 is provided with a plurality of universal wheels 21 (with a braking function) to facilitate the movement of the cover placing frame 22.
