[0033] This embodiment provides a coal sample collection device. Specifically, Figure 1 and Figure 2 As shown, the coal sample collection device includes a bagging assembly 1, a collecting member 2 and a lifting drive member 3. The bagging assembly 1 includes a funnel 11 and a vibrator 12, and the vibrator 12 is connected to the outer wall of the funnel 11; the collecting member 2 is hollow inside and has an open top, and the bagging assembly 1 can be placed in the collecting member 2, and a dust removal pipe 211 is connected to the outer wall of the collecting member 2, one end of the dust removal pipe 211 is connected to the inner cavity of the collecting member 2, and the other end is connected to a vacuum pump; the lifting drive member 3 can drive the bagging assembly 1 to extend from the opening at the top of the collecting member 2 or retract the collecting member 2.

[0034] The coal sample collection device provided in this embodiment is provided with a lifting drive 3. When the bagging process is carried out, the lifting drive 3 can drive the bagging assembly 1 to rise, so that an operating space conducive to bagging can be formed between the bagging assembly 1 and the collecting member 2. When the bagging process is not required, the lifting drive 3 can drive the bagging assembly 1 to retract the collecting member 2, thereby reducing the space occupied and the possibility of the coal powder remaining on the funnel 11 being blown onto the ground, thereby reducing the intensity of the work of cleaning the ground. In addition, a vibrator 12 is provided on the funnel 11 to achieve the effect of vibrating the coal fragments and coal powder remaining on the funnel 11 into the bag or inside the collecting member 2, thereby reducing the frequency of cleaning the funnel 11 and reducing the labor intensity. In addition, a dust removal pipe 211 is provided on the collecting member 2 to also achieve the effect of sucking out coal powder, thereby further reducing the possibility of coal powder falling onto the ground.

[0035] like Figure 1 The figure shows the storage state of the coal sample collection device, where the bagging assembly 1 is placed inside the collection piece 2, and preferably, the top of the bagging assembly 1 is not higher than the top surface of the collection piece 2, so that the bagging assembly 1 is stored in the collection piece 2, further reducing the space occupied by the coal sample collection device. Figure 2 The figure shows the extended state of the coal sample collecting device, where the lifting drive 3 drives the bagging assembly 1 to extend out of the collecting member 2, and preferably, the bottom of the bagging assembly 1 is not lower than the top surface of the collecting member 2, so as to facilitate the bagging process.

[0036] In the present embodiment, the coal sample collection device further comprises a base, and the collection member 2 is fixed on the base, and the base is fixedly arranged.

The collecting hopper 22 is placed below the dust collecting frame 21, and the top of the collecting hopper 22 is provided with an opening, and the top opening of the collecting hopper 22 is arranged opposite to the bottom opening of the dust collecting frame 21, that is, the top opening of the dust collecting frame 21 is formed as the top opening of the collecting member 2. The dust removal pipe 211 is arranged on the dust collecting frame 21; so that the coal powder is sucked out through the dust removal pipe 211, and the coal fragments fall into the collecting hopper 22, which reduces the amount of coal powder falling into the collecting hopper 22 and facilitates the subsequent treatment of the coal fragments. In this embodiment, the dust collecting frame 21 and the collecting hopper 22 are separately arranged. The collecting member 2 is divided into two parts, the dust collecting frame 21 and the collecting hopper 22, which is convenient for replacing the dust collecting frame 21 and the collecting hopper 22 separately, reducing the maintenance cost, and also convenient for disassembling and cleaning the collecting member 2, improving the practicality.

[0038] In other embodiments, the dust collection frame 21 and the collecting bucket 22 are detachably connected, so that when the collecting member 2 collects coal fragments and coal powder, no movement occurs between the dust collection frame 21 and the collecting bucket 22, thereby ensuring the collection function of the collecting member 2 for the coal fragments.

[0039] Specifically, the collecting member 2 is provided with a fixing member 212, which is arranged in a cylindrical shape, vertically arranged, and opened at the upper end. The bottom wall of the fixing member 212 forms a bearing wall for bearing the lifting drive member 3. The lifting drive member 3 is placed in the fixing member 212 and on the bearing wall. The lifting drive member 3 is fixedly connected to the bearing wall to achieve a fixed connection between the lifting drive member 3 and the collecting member 2. The lifting drive member 3 and the fixing member 212 can be connected by screws or adhesive, which is not limited here. In other embodiments, the fixing member 212 can be columnar and vertically arranged, and the lifting drive member 3 is placed on the top of the fixing member 212.

[0041] Preferably, the lifting drive member 3 includes a fixing portion 31 and an output end 32, wherein the fixing portion 31 is fixedly disposed in the collecting member 2, and the output end 32 is disposed in the fixing portion 31 and can extend from the top of the fixing portion 31, and the top of the output end 32 is connected to the bagging assembly 1, specifically to the outer wall of the funnel 11. The lifting drive member 3 has a simple structure and is disposed inside the collecting member 2, which plays a protective role for the lifting drive member 3 and improves the durability of the lifting drive member. Furthermore, the fixing portion 31 is fixedly connected to the fixing member 212.

[0042] In this embodiment, the lifting drive member 3 is a cylinder, whose cylinder body is formed as a fixed portion 31, and the piston rod is formed as an output end 32, and the piston rod can extend out of the top of the cylinder body to realize the lifting function of the lifting drive member 3. In other embodiments, the lifting drive member 3 can also be a linear motor or other structure, which is not limited here.

[0043] Preferably, if Figure 1-Figure 3 As shown, the bagging assembly 1 further includes a bearing plate 13, which is in the shape of a circular plate and has a diameter smaller than the inner diameter of the dust collecting frame 21. A feed port is arranged at the top of the funnel 11, and a discharge port is arranged at the bottom. The bearing plate 13 is placed below the funnel 11 and is spaced apart from the discharge port. The maximum diameter of the funnel 11 is smaller than the inner diameter of the dust collecting frame 21. The bearing plate 13 is arranged so that when the bagging process is performed, the bearing plate 13 can play the role of bearing the bag at the bottom of the bag, which reduces the workload of the operator and improves practicality.

[0044] In this embodiment, a discharge extension section 111 is provided at the discharge port of the funnel 11. When the bagging process is carried out, the discharge extension section 111 can extend into the bag to prevent the coal sample from falling outside the bag and reduce the workload of cleaning the ground.

[0045] Furthermore, if Figure 1-Figure 4 As shown, a plurality of through holes 132 are provided on the supporting plate 13, and the plurality of through holes 132 are arranged in an array on the supporting plate 13, so that the coal fragments and coal powder dropped on the supporting plate 13 can enter the collecting member 2 through the through holes 132, thereby avoiding manual cleaning of the supporting plate 13 and reducing the labor intensity of cleaning the ground.

[0046] Furthermore, the bagging assembly 1 further includes a connecting member 14, the top end of the connecting member 14 is connected to the outer wall of the funnel 11, the bottom end is connected to the carrying plate 13, and the output end 32 is connected to the funnel 11. The connecting member 14 is provided to enable the bagging assembly 1 to form an integral structure, reduce the connection position between the lifting drive member 3 and the bagging assembly 1, and facilitate production and processing.

[0047] In the present embodiment, the connecting member 14 is rod-shaped and vertically arranged. A connecting hole 133 is provided on the bearing plate 13, and the bottom of the connecting member 14 is inserted into the connecting hole 133. Furthermore, the connecting hole 133 is a threaded hole, and the bottom of the outer wall of the connecting member 14 is provided with an external thread.

In other embodiments, the connecting member 14 and the funnel 11 and the bearing plate 13 can also be connected by welding, which is not limited here.

[0048] Preferably, an escape opening 131 is provided at the edge of the carrier plate 13, and the lifting drive member 3 is placed in the escape opening 131. The above-mentioned structural arrangement improves the compactness of the bagging assembly 1 and the lifting drive member 3, and reduces the space occupied by the coal sample collection device. The escape opening 131 is in an arc shape.

[0049] Furthermore, the fixing member 212 can be placed inside the avoidance opening 131 , thereby avoiding interference between the fixing member 212 and the supporting plate 13 , and ensuring that the bagging assembly 1 can be smoothly lifted and lowered and stored inside the collecting member 2 .

[0050] Preferably, the coal sample collection device also includes a weighing component, which includes a gravity sensor. The gravity sensor can detect the weight of the coal sample on the bagging component 1, so that the coal sample collection device can directly weigh the coal sample of the required weight, enriching the function of the coal sample collection device and improving the practicality of the coal sample collection device.

[0051] Furthermore, the weighing assembly also includes a sticker printout, which is connected to the gravity sensor signal, and can print the weight of the coal sample detected by the gravity sensor on the sticker. After weighing, the sticker is directly attached to the bag, further enriching the function of the coal sample collection device and improving the practicality of the coal sample collection device. Among them, the sticker printout can adopt the structure of a printer in the prior art, which will not be repeated here.

[0052] It is worth noting that the communication method and control method between the gravity sensor and the sticker print can adopt existing technologies and will not be repeated here.

[0053] In this embodiment, the gravity sensor is placed between the lifting drive member 3 and the bearing wall, that is, the gravity sensor is placed at the bottom of the fixing portion 31 of the lifting drive member 3. It can be understood that when no coal sample is placed on the bagging assembly 1, the initial weight measured by the gravity sensor is the total weight of the lifting drive member 3 and the bagging assembly 1. When the coal sample is placed on the bagging assembly 1, the calculated weight measured by the gravity sensor is the total weight of the coal sample, the lifting drive member 3 and the bagging assembly 1. Then, the weight of the coal sample = calculated weight - initial weight.
