[0026] The dust-proof sample receiving device of this utility model includes a dust-collecting component 4, a receiving door 5, a frame 3, and a coal-receiving component 8. The coal-receiving component 8 is disposed inside the frame 3, and the receiving door 5 is rotatably disposed on the frame 3. The top of the coal-receiving component 8 is provided with an inlet, and the receiving door 5 can rotate relative to the frame 3 to open or close the inlet of the coal-receiving component 8. The dust-collecting component 4 is disposed on the top of the frame 3 and includes a dust-collecting part 41, a dust-collecting pipe 42, and a dust-collecting box 43. The dust-collecting box 43 is disposed on the top of the frame 3. The receiving door 5 is connected to one end of the dust-collecting pipe 42, and the receiving door 5 is provided with a vent hole so that the dust-collecting pipe 42 can absorb dust through the vent hole. The dust-collecting part 41 is connected to the dust-collecting pipe 42 and the dust-collecting box 43.
[0027] Specifically, such as Figures 1 to 5 As shown, the frame 3 includes a frame body 31 and a front panel 32. The front panel 32 is located on the top of the frame body 31. A dust collection box 43 and a receiving door 5 are installed on the front panel 32. The coal receiving assembly 8 is located inside the frame 3, that is, inside the frame body 31. The front panel 32 has an opening to facilitate the receipt of sample pieces by the inlet of the coal receiving assembly 8, that is, the sample piece bucket is placed on the front panel 32.
[0028] The dust collection component 4 is mounted on the frame 3 and is used to collect dust during the use of the device.
[0029] The vacuuming assembly 4 includes a vacuum pipe 42, a vacuum component 41, and a vacuum box 43. The vacuum box 43 is mounted on the front panel 32. The vacuum component 41 is connected to both the vacuum pipe 42 and the vacuum component 43. The vacuum component 41 can be an existing vacuuming device, vacuuming equipment, or dust collector. The vacuum component 41 is adapted to absorb dust through the vacuum pipe 42 or the vacuum box 43. The receiving door 5 is provided with a vent hole for collecting dust. The vent hole can be circular, elliptical, or rectangular, etc.
[0030] The dust-proof sample receiving device of this utility model, by setting up a dust suction component 4, can collect dust during the sample collection process and avoid dust pollution.
[0031] In some embodiments, the dust collection box 43 is provided with a dust collection hole 431, which extends downward at an angle.
[0032] Specifically, such as Figures 1 to 5 As shown, the suction hole 431 is rectangular in shape. The suction hole 431 is provided on the side of the dust collection box 43. The suction hole 431 extends in the left and right direction and slopes downward to prevent the sucked-in dust from entering the suction hole 431 and overflowing into the dust collection box 43.
[0033] In some embodiments, there are multiple dust collection boxes 43, which are arranged at intervals in the circumferential direction of the frame 3.
[0034] Specifically, such as Figures 1 to 5 As shown, the dust collection boxes 43 are arranged at intervals in the front-to-back direction. The dust collection boxes 43 have cavities inside. The dust collection boxes 43 are connected to the dust collection components 41 so that the cavity communicates with the output end of the dust collection components 41. The cavity communicates with the dust collection holes 431, which facilitates the suction of dust into the dust collection boxes 43 through the dust collection holes 431 and the passage of dust into the subsequent dust collection components 41.
[0035] In some embodiments, the coal receiving assembly 8 includes a primary coal hopper component 81 and a vibration component. The bottom of the vibration component is connected to the frame 3, and the output end of the vibration component faces the primary coal hopper component 81.
[0036] Specifically, such as Figures 1 to 5 As shown, the primary coal hopper component 81 is connected to the frame 3, and the output end of the vibration component is connected to the primary coal hopper component 81. This ensures that when the vibration component is activated, it is either in contact with or away from the primary coal hopper component 81, vibrating the primary coal hopper component 81 as much as possible to completely remove the sample from it and avoid cross-contamination. The vibration component can be an existing vibration component, vibration motor, or vibration equipment, etc.
[0037] In some embodiments, the primary coal hopper component 81 includes a weighing element 812, a gate 813, a gate 813 opening and closing cylinder, and a primary coal hopper 811. The primary coal hopper 811 is connected to the weighing element 812, which is mounted on the frame 3. The gate 813 opening and closing cylinder and the gate 813 are rotatably mounted on the primary coal hopper 811. The primary coal hopper 811 has an outlet at its bottom. The gate 813 opening and closing cylinder drives the gate 813 to rotate to open or close the outlet of the primary coal hopper 811.
[0038] Specifically, such as Figures 1 to 5As shown, the weighing component 812 is mounted on the frame 3. The upper end of the weighing component 812 is connected to the bottom of the primary coal hopper 811. The bottom of the primary coal hopper 811 is provided with a rotatable gate 813, and the side wall of the primary coal hopper 811 is provided with a gate cylinder 814. The top of the gate cylinder 814 is rotatably connected to the top of the primary coal hopper 811, and the other end of the gate cylinder 814 is rotatably connected to the gate 813. The gate cylinder 814 extends and retracts to rotate the gate 813 to open or close the outlet at the lower end of the primary coal hopper 811, thereby facilitating the weighing of the primary coal hopper 811 or the release of the sample from the primary coal hopper 811. This allows the outlet of the primary coal hopper 811 to be closed immediately after receiving the sample for weighing. After weighing, the gate cylinder 814 retracts to open the opening of the primary coal hopper 811, thus eliminating the need for manual weighing and improving the automation level of the device.
[0039] Furthermore, the water volume of gate 813 and gate cylinder 814 can be two, and gate 813 and gate cylinder 814 are arranged relatively alternately on both sides of the primary coal hopper 811 in the front and rear direction, thereby improving the stability of opening and closing the outlet of primary coal hopper 811.
[0040] In some embodiments, the coal receiving assembly 8 further includes a sealing curtain 83 and a secondary coal hopper 82, with the primary coal hopper 811 partially extending into the secondary coal hopper 82, one end of the sealing curtain 83 connected to the top of the secondary coal hopper 82, and the other end of the sealing curtain 83 connected to the outer peripheral surface of the primary coal hopper 811.
[0041] Specifically, such as Figures 1 to 5 As shown, the sealing curtain 83 is set between the secondary coal hopper 82 and the primary coal hopper 811 to prevent dust from appearing in the gap between the primary coal hopper 811 and the secondary coal hopper 82 in the front-to-back direction. At the same time, an inlet can be set at the lower end of the dust collection box 43, which is connected to the cavity of the dust collection box 43 and faces the sealing curtain 83, so that the dust collection component 41 can absorb the dust during operation and avoid cross-contamination of dust.
[0042] In some embodiments, the dust-proof sample receiving device further includes a door-opening cylinder 7. A hinge 6 is provided between the receiving door 5 and the frame 3, and the hinge 6 is connected to both the frame 3 and the receiving door 5. One end of the door-opening cylinder 7 is rotatably connected to the frame 3, and the other end is connected to the receiving door 5. By providing the door-opening cylinder 7, the door-opening cylinder 7 extends and retracts in the vertical direction, so that the receiving door 5 on the front panel 32 of the frame 3 can rotate, so that the sample bucket 1 can be placed on the frame 3, and the sample bucket 1 and the primary coal hopper 811 are arranged opposite each other in the vertical direction.
[0043] For example, the sample receiving device can be docked with the sample container 1. When receiving a sample, the receiving door 5 is automatically opened by the opening cylinder 7, and the sample preparation device uses a robotic arm to place the sample container 1 on the receiving device.
[0044] When the device receives a sample, the weighing part 812 is zeroed, the receiving door 5 is opened, the gate 813 is closed, and the dust suction part 41 is turned on to suck away the dust.
[0045] After all the samples have entered the receiving device, remove sample container 1, close receiving door 5, turn off the dust collection device, and record the data of weighing device 812.
[0046] After weighing the sample, turn on the dust collection component 41 and the gate 813 to discharge the sample into the next stage of equipment.
[0047] This enables automated weighing and dust removal of samples, improving the automation level of the device. Furthermore, the automatic dust removal process prevents cross-contamination of the samples with dust.
[0048] In some embodiments, there are multiple weighing elements 812, which are arranged on the frame 3. The upper end of the weighing element 812 is connected to the primary coal hopper 811, and the lower end of the weighing element 812 is connected to the frame body 31 to improve the stability of the primary coal hopper 811 during use. Furthermore, by setting multiple weighing elements 812, the stability of weighing can be increased.
[0049] In some embodiments, the dust-proof sample receiving device further includes a support leg 2, which is connected to the bottom of the frame 3 to support the frame 3 and improve the stability of the frame 3.
[0050] In some embodiments, the bottom of the dust collection box 43 is provided with an inlet facing the coal receiving assembly 4. The inlet faces the sealing curtain 83, the primary coal hopper 811, and the secondary coal hopper 82 to draw in dust and prevent dust from contaminating the sample.
