[0048] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0049] The following is in conjunction with the appendix Figures 1 to 12 This invention describes an automatic coal sampler loading and unloading device according to an embodiment of the present invention.

[0050] like Figures 1 to 12 As shown, the automatic coal sampler loading and unloading device of this embodiment includes a main support 1, a lid-releasing frame 22, a container loading conveying assembly 3, a lid-releasing assembly 4, a container unloading conveying assembly 5, and a container pushing assembly 6. Wherein:

[0051] The main support 1 is composed of multiple steel pipes welded diagonally 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.

[0052] The lid holder 22 is used to store the lid of the sample collection bucket and facilitates the mechanical claw 43 to grasp it. The lid holder 22 is detachably connected to the main support 1 by bolts, buckles, wire binding or other means to avoid relative movement between the lid holder 22 and the main support 1, which would prevent the mechanical claw 43 from properly grasping the lid of the sample collection bucket.

[0053] The inlet conveying assembly 3 is connected to the main support 1 and is used to convey the sample collection bucket into the main support 1.

[0054] like Figures 2 to 4 As shown, specifically, the barrel feeding conveyor assembly 3 includes a first fixed frame 31 and a plurality of first idlers 32, the first fixed frame 31 being located on the first side of the main support 1 (e.g., Figure 3 The sample collection bucket (shown on the rear side) is fixedly installed on the ground. Multiple first rollers 32 are connected to the first fixed frame 31 and are spaced apart along the length of the first fixed frame 31 so that the sample collection bucket can move smoothly along the length of the first fixed frame 31. Multiple first rollers 32 are used to support and transport the sample collection bucket. Multiple first rollers 32 are driven by one or more chains at the same time to avoid the sample collection bucket tipping over or failing to move normally to the set position due to inconsistent rotation speed of the first rollers 32.

[0055] The lid-laying assembly 4 includes a crossbeam 41, a sliding frame 42, and a mechanical claw 43. There are multiple crossbeams 41, all connected to the main support 1 and spaced apart along the vertical direction. The length direction of the crossbeams 41 is along a first direction (e.g., ...). Figure 1 The left and right directions are shown. The first direction is orthogonal to the up and down direction. The sliding frame 42 is connected to the crossbeam 41 and can move along the length of the crossbeam 41. The mechanical claw 43 is connected to the sliding frame 42 and can move along the up and down direction on the sliding frame 42. The mechanical claw 43 is designed to be able to grab the lid on the lid holder 22 and place and fix it on the sample collection bucket.

[0056] like Figure 1 and Figure 2 As shown, specifically, the sliding frame 42 includes a first slide 421, a second slide 422, and a connecting member 423. The first slide 421 is connected to one of the crossbeams 41, and the length direction of the first slide 421 is along the length direction of the crossbeam 41. The second slide 422 is connected to the slider of the first slide 421, so that the entire second slide 422 can move along the length direction of the first slide 421 with the slider of the first slide 421. Moreover, the second slide 422 is slidably connected to multiple crossbeams 41 to ensure the stability of the second slide 422 during movement. The length direction of the second slide 422 is along the vertical direction. The connecting member 423 is connected to the slider of the second slide 422 and is provided with a positioning groove 4231 that matches the mechanical claw 43. The mechanical claw 43 is detachably connected to the connecting member 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. The mechanical claw 43 can move vertically and horizontally via the first slide 421 and the second slide 422, so that the mechanical claw 43 can grasp and place the lid.

[0057] It should be noted that the first slide 421, the second slide 422 (and the third slide 61 hereinafter referred to as the third slide) in this embodiment of the present invention are all slides commonly used in the art, containing a base, guide rail, slider, drive system and other auxiliary components. Their specific structural composition and operating principle are all commonly used in the art, and will not be described in detail here.

[0058] like Figure 2 As shown, the sliding frame 42 further includes a first inductive switch 424, which is connected to the base of the second slide 422. The first inductive switch 424 is used to detect whether the mechanical claw 43 has moved to the set position. When the mechanical claw 43 moves to the set position, the first inductive switch 424 sends a signal to the control system, and the control system controls the mechanical claw 43 to stop moving and install the cover on the sample collection bucket.

[0059] like Figure 1 , Figure 2 , Figures 5 to 7 As shown, specifically, the mechanical gripper 43 includes a support base 431, a drive member 432, a gear 433, a rack 434, limiting members 435, and grippers 436. The support base 431 is connected to the sliding frame 42. The drive member 432 (e.g., a motor) is connected to the support base 431 and located above it. The gear 433 is sleeved on the output shaft of the drive member 432, which drives the gear 433 to rotate. There are at least two racks 434, all connected to the support base 431 and meshing with the gear 433. The racks 434 are spaced apart circumferentially along the gear 433, allowing them to move in different directions. There are at least two limiting members 435, all of which are... Connected within the support base 431, multiple limiting members 435 correspond one-to-one with multiple racks 434. The limiting members 435 are used to limit the movement range of the corresponding racks 434 to prevent the mechanical claw 43 (and gripper 436) from moving excessively. There are at least two grippers 436, with multiple grippers 436 corresponding one-to-one with multiple racks 434. The grippers 436 are connected to the corresponding racks 434 and located outside the support base 431 so that when the racks 434 move, the grippers 436 can simultaneously move towards or away from the gears 433 to complete the gripping and releasing action of the mechanical claw 43.

[0060] like Figure 2 and Figure 6 As shown, the mechanical gripper 43 also includes a second inductive switch 437. The second inductive switch 437 is connected to the support base 431, and the trigger part of the second inductive switch 437 is located below the support base 431. The second inductive switch 437 is used to detect whether the mechanical gripper 43 is in contact with or separates from the cover. When the cover is being gripped, when the second inductive switch 437 senses that the mechanical gripper 43 is in contact with the cover, the second inductive switch 437 sends a signal to the control system. The control system controls the mechanical gripper 43 to stop moving and grip the cover.

[0061] The outflow conveying assembly 5 is connected to the main support 1 and is used to convey the capped and locked sample collection bucket to the recycling position.

[0062] like Figures 2 to 4 As shown, specifically, the barrel conveying assembly 5 includes a second fixed frame 51 and a plurality of second idlers 52, the second fixed frame 51 being located on the second side of the main support 1 (e.g., Figure 3As shown on the right side, the sample collection bucket is fixedly installed on the ground. Multiple second rollers 52 are connected to the second fixed frame 51 and are spaced apart along the length of the second fixed frame 51 so that the sample collection bucket can move smoothly along the length of the second fixed frame 51. Multiple second rollers 52 are used to support and transport the sample collection bucket. Multiple second rollers 52 are driven by one or more chains at the same time to avoid the sample collection bucket tipping over or failing to move normally to the set position due to inconsistent rotation speed of the second rollers 52.

[0063] The pusher assembly 6 is connected to the main support 1 and is used to push the sample collection bucket from the inlet conveyor assembly 3 to the outlet conveyor assembly 5.

[0064] like Figure 3 , Figure 9 and Figure 10 As shown, specifically, the pusher assembly 6 includes a third slide 61, a pusher arm 62, and a positioning baffle 63. The third slide 61 is connected to the main support 1. One end of the pusher arm 62 is connected to the slider of the third slide 61, so that the pusher arm 62 can move along the length of the third slide 61 with the slider of the third slide 61. The other end of the pusher arm 62 is used to push the sample collection bucket, and an arc-shaped plate matching the sample collection bucket is installed on the other end of the pusher arm 62 to ensure the stability of the pusher arm 62 when pushing the sample collection bucket. The positioning baffle 63 is connected to the base of the third slide 61. The positioning baffle 63 is provided with a limiting groove for limiting the movement range of the pusher arm 62, thereby ensuring that the pusher arm 62 stops accurately at a predetermined position and avoids damage or misoperation due to excessive movement.

[0065] In use, after assembling the main support 1 and the lid-laying frame 22, the sample collection bucket is placed in the bucket infeed conveyor assembly 3 by manual operation or machine. The bucket infeed conveyor assembly 3 transports the sample collection bucket to a designated position within the main support 1 for sample collection. After sample collection, the sliding frame 42 moves the mechanical claw 43 to directly above the lid-laying frame 22. Subsequently, the second sliding table 422 moves the mechanical claw 43 downwards until it contacts the lid. The driving component 432 drives the gear 433 to rotate forward. The gear 433, through the rack 434, drives the gripper 436 to move towards the gear 433. The lid is gripped; then the sliding frame 42 moves the mechanical claw 43 to directly above the sample collection bucket, and the second slide 422 moves the mechanical claw 43 downward until the first sensor switch 424 detects that the mechanical claw 43 has moved to the set position; the drive unit 432 drives the gear 433 to rotate in the opposite direction, and the gear 433 drives the gripper 436 to move in the direction of the original gear 433 through the rack 434 to complete the installation of the lid and the separation of the mechanical claw 43 and the lid; then the mechanical claw 43 resets, and at the same time the bucket pusher assembly 6 transports the lidped and locked sample collection bucket to the recycling position to complete one cycle.

[0066] The automatic sampler loading and unloading device of this utility model realizes the functions of automatic loading and unloading of the sample collection bucket, automatic lid placement and automatic conveying through automated control, which greatly improves sampling efficiency and accuracy, and reduces labor costs and safety risks.

[0067] like Figure 2 As shown, in some embodiments, the automatic coal sampler loading and unloading device further includes a third sensor switch 7 and a fourth sensor switch 8.

[0068] The third sensor switch 7 is connected inside the main support 1. The third sensor switch 7 is used to detect whether the sample collection bucket has reached the designated position (for example, when the sample collection bucket contacts the third sensor switch 7, the third sensor switch 7 will send a signal indicating that the sample collection bucket is ready for sampling). The type of the third sensor switch 7 can be selected according to actual needs, such as photoelectric switch, proximity switch, etc., to ensure that the position of the sample collection bucket can be detected accurately and reliably.

[0069] The fourth sensor switch 8 is connected to the first fixed part. The fourth sensor switch 8 is used to detect whether a sample collection bucket has passed by. When the sample collection bucket moves on the bucket inlet conveyor assembly 3 and passes the fourth sensor switch 8, the switch will send a signal indicating that a sample collection bucket is entering the sampling area. The fourth sensor switch 8 can also be selected according to actual needs, such as photoelectric switch, magnetic induction switch, etc., to ensure that the presence of the sample collection bucket can be detected accurately and in a timely manner.

[0070] During device operation, when the third sensor switch 7 senses that a sample collection bucket has arrived at the designated position, the control system receives the signal and prepares to perform sampling. At the same time, the fourth sensor switch 8 continuously monitors the sample collection bucket on the bucket infeed conveyor assembly 3. When the third sensor switch 7 senses that a sample collection bucket has arrived at the designated position and the fourth sensor switch 8 detects that a sample collection bucket has passed by, the bucket infeed conveyor assembly 3 stops working to prevent multiple sample collection buckets from entering the main support 1 at the same time, thereby improving the safety and sampling efficiency of the device.

[0071] Therefore, the automatic coal sampler loading and unloading device of this utility model embodiment, by adding a third inductive switch 7 and a fourth inductive switch 8, realizes accurate detection of the sample collection bucket position and intelligent control of the conveying components, which not only improves the automation level and safety of the sampling process, but also helps to reduce human intervention and misoperation.

[0072] like Figure 3 As shown, optionally, the length direction of the first fixing frame 31 is along the second direction (e.g., Figure 3 The second direction is set in the front-back direction (as shown), the second direction is orthogonal to the vertical direction, and the length direction of the second fixing bracket 51 is along the third direction (e.g., the front-back direction). Figure 3The orthogonal layout (shown in the left and right directions) allows the inlet conveyor assembly 3 and the outlet conveyor assembly 5 to be arranged in different directions, thereby increasing the flexibility of the device layout.

[0073] like Figure 4 As shown, optionally, the first fixing bracket 31 and the second fixing bracket 51 are along the second direction (e.g., Figure 4 The fixtures are spaced apart in the left and right directions (as shown), and the length directions of the first fixture 31 and the second fixture 51 are both along a third direction (e.g., ...). Figure 4 As shown in the front-to-back direction, this parallel layout is suitable for sampling sites with limited space or requiring a compact arrangement. By arranging the inlet conveyor assembly 3 and the outlet conveyor assembly 5 in parallel, the horizontal footprint of the device can be minimized while maintaining a smooth and efficient conveying path.

[0074] Therefore, the automatic coal sampler loading and unloading device of this utility model embodiment can be flexibly arranged according to the specific conditions of the sampling site, such as space size, conveying path requirements, and coordination with other equipment, thereby increasing the flexibility and adaptability of the device.

[0075] like Figure 3 and Figure 9 As shown, in some embodiments, the automatic coal sampler loading and unloading device also includes multiple unpowered rollers 9. The multiple unpowered rollers 9 are all installed in the main support 1 and are located between the loading conveying assembly 3 and the unloading conveying assembly 5. The unpowered rollers 9 are used to provide auxiliary support and guidance for the sample collection bucket, reduce the wear on the sample collection bucket and equipment when the bucket pushing assembly 6 pushes the sample collection bucket, and ensure that the sample collection bucket can move smoothly and stably during the conveying process.

[0076] like Figure 11 and Figure 12 As shown, in some embodiments, the main support 1 is provided with a positioning element 11, and the cover holder 22 is provided with a positioning hole that matches the positioning element 11. When the cover holder 22 needs to be installed on the main support 1, the positioning hole is aligned with the positioning element 11 and inserted to achieve quick and accurate positioning of the cover holder 22. This not only improves the stability and accuracy of the installation of the cover holder 22, but also helps to reduce installation time and cost.

[0077] like Figure 1 and Figure 2 As shown, in some embodiments, the main support 1 is provided with multiple fixed supports 12 at the bottom to securely fix the main support 1 in a set position, and the cover rack 22 is provided with multiple (with braking function) universal wheels 21 at the bottom to facilitate the movement of the cover rack 22.
