For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0025] The following is combined with Figure 1 To the attached Figure 6 The present application is further described in detail with reference to specific embodiments.

[0026] In the present application, a sample filling and combing device for harsh environments is disclosed, which is used to quantitatively fill mined mineral or coal samples into sampling bottles 50. The sample filling and combing device includes a frame 10, a filling cabin 20 arranged on the frame 10, a lower hopper 30 arranged on the top of the filling cabin 20, and a sample bottle conveyor belt 40. The frame 10 is fixed to the ground and is used as a base for installing various accessories and the filling cabin 20. The filling cabin 20 is a cabin body with an independent space composed of a frame, a floor, a top plate and side wall panels. The floor of the filling cabin 20 is arranged on the top of the frame 10, and the lower hopper 30 is arranged on the top plate and its discharge port extends downward through the top plate into the filling cabin 20. In the internal space of the filling cabin 20, a sample bottle combing mechanism 11 is rotatably provided on the top of the frame 10. The sample bottle combing mechanism 11 is a structure for combing the sample bottles. The mechanism 11 is used to drive the sampling bottle 50 to move along a circular trajectory on the bottom surface of the filling chamber 20; along the circular movement trajectory of the sampling bottle 50, the filling area is located directly below the discharge port of the frame 10 relative to the lower hopper 30, and a sample bottle weighing mechanism 12 is provided in the filling area. A sample bottle delivery port 21 is provided on the side of the filling chamber 20, and one end of the sample bottle conveyor belt 40 extends into the sample bottle delivery port 21 and intersects with the circular movement trajectory of the above-mentioned sampling bottle 50. The sample bottle conveyor belt 40 is used to input or output the sampling bottle 50 into or out of the sample bottle delivery port 21. The area at the above-mentioned intersection is the initial position of the sampling bottle 50 when it is transported from the outside to the inside of the filling chamber 20 by the sample bottle conveyor belt 40.

[0027] Specifically, the feeding end of the discharge hopper 30 is connected to a discharge valve or a pneumatic sample feeding device, which is used to control the sample discharge process of the discharge port of the discharge hopper 30; the sample bottle weighing mechanism 12 can at least obtain information on whether an empty sampling bottle 50 has arrived at the filling area below the discharge port and the sample filling weight in the sampling bottle 50, and the obtained information is fed back to the discharge valve or the pneumatic sample feeding device of the discharge hopper 30, so that the discharge hopper 30 starts to fill the sample into the sampling bottle 50 or stops filling; the sample bottle conveyor belt 40 continuously transports a number of sampling bottles 50 to the above-mentioned initial position, and at the same time, the sample bottle combing mechanism 11 rotates at a set speed, and drives the sampling bottles 50 that have successively entered the sample bottle conveying port 21 along a circular trajectory on the floor of the filling cabin 20, so that the sampling bottles 50 are delivered to the filling cabin in the order of entry, filling area; when the sample bottle weighing mechanism 12 senses that an empty sampling bottle 50 has arrived at the filling area below the discharge port, it feeds back to the sample bottle combing mechanism 11 to stop rotating so that the lower hopper 30 can fill the sample bottle material into the sampling bottle 50; the sample bottle conveyor belt 40 only needs to place a corresponding number of sampling bottles 50 according to the total weight of the samples taken in different time periods or batches, so as to complete the work of distinguishing sampling; when several empty sampling bottles 50 entering the filling chamber 20 are successively filled with samples, the above-mentioned sample bottle conveyor belt 40 is controlled to reversely convey the sampling bottles 50, and at the same time, the sample bottle combing mechanism 11 is controlled to rotate intermittently so that the filled sampling bottles 50 return to the initial area one after another, so that they are output from the filling chamber 20 from the sample bottle conveying port 21 by the sample bottle conveyor belt 40 in the reverse direction and transported to the designated location.

[0028] The use of the above-mentioned sample bottle filling and combing device has at least the following beneficial effects: the sample bottle conveyor belt 40 continuously inputs a plurality of sampling bottles 50 into the filling chamber 20, and at the same time the sample bottle combing mechanism 11 intermittently drives the sampling bottles 50 to move along a circular trajectory, so that the empty sampling bottles 50 can successively arrive at the bottom of the lower hopper 30 and be filled with samples. The samples are quantitatively and separately filled into multiple sampling bottles 50, which not only improves the unloading efficiency, but also can isolate a large amount of dust raised by unloading in the filling chamber 20 during the filling process to prevent pollution of the working environment outside the chamber, and effectively prevents the dust generated by samples collected in different time periods from mixing with each other and causing sample contamination. The device automatically performs quantitative filling and transportation operations of the sampling bottles 50, so as to distinguish and sample the samples taken in each time period. Compared with the existing technology, the device does not require manual participation in the unloading and sampling processes, saving labor costs.

[0029] In addition, this application also provides some more specific implementation methods to improve the above-mentioned sample filling and combing device.

[0030] Furthermore, in a preferred embodiment, the sample bottle sorting mechanism 11 includes a central rotating column 111 and a driving motor 112. The central rotating column 111 passes through the floor of the filling chamber 20 and is rotatably connected to the frame 10 through a bearing. It is located above the floor of the filling chamber 20. A plurality of fixed disks 1111 are axially arranged on the surface of the central rotating column 111. The fixed disks 1111 are divergently arranged with a plurality of sample bottle toggle rods 1112 along their circumferences. A gap that can accommodate at least one sampling bottle 50 is formed between adjacent sample bottle toggle rods 1112. It is located below the floor of the filling chamber 20. The housing of the driving motor 112 is fixed to one side of the frame 10. The output shaft of the driving motor 112 is connected to the central rotating column 111 through a rotating transmission component such as gears.

[0031] When the above-mentioned sample bottle sorting mechanism 11 is used, the driving motor 112 cooperates with the sample bottle conveyor belt 40. The driving motor 112 drives the central rotating column 111 to rotate intermittently, so that the gap between any pair of adjacent sample bottle toggling rods 1112 is opposite to the sample bottle conveying port 21. At the same time, the sample bottle conveyor belt 40 conveys the spaced sampling bottles 50 into the above-mentioned gap. The sampling bottles 50 are toggled along a circular trajectory by the sample bottle toggling rods 1112, so that the sample bottles that enter the filling chamber 20 one after another are moved to the bottom of the lower hopper 30 for filling of samples.

[0032] Furthermore, the number of the above-mentioned fixed plates 1111 is a pair.

[0033] Specifically, a pair of fixed plates 1111 are arranged at intervals in the upper and lower directions along the axis of the central rotating column 111. The upper and lower groups of sample bottle toggle rods 1112 respectively arranged on the pair of fixed plates 1111 can simultaneously apply thrust to the upper and lower ends of the sampling bottle 50, which is beneficial to increase the force-bearing area of ​​the sampling bottle 50 and make the sampling bottle 50 more stable during movement.

[0034] Furthermore, in order to prevent the sampling bottle 50 from sliding between the sample bottle toggle rod 1112 due to centrifugal force during the pushing process, a paddle 1113 is provided at the end of the sample bottle toggle rod 1112 away from the fixed disk 1111, and the paddle 1113 points in the direction of the paddle 1113 along the axis of the central rotating column 111. The paddle 1113 makes the gap between the sample bottle toggle rods 1112 converge away from the side of the central rotating column 111.

[0035] Specifically, the above-mentioned paddle 1113 is a flexible material piece in the shape of a triangle, a body or a fan, and the side with a narrower outline width is connected to the sample bottle paddle rod 1112, and the side with a larger outline width faces outward, so that the gap between adjacent sample bottle paddle rods 1112 changes from an outward expansion trend to a convergence trend within the length range of the paddle 1113. The convergent part of the gap can have a limiting effect on the sampling bottle 50 that tends to slide outward due to centrifugal force, thereby avoiding excessive displacement of the sampling bottle 50 in the radial direction of the moving trajectory, resulting in the bottle mouth of the sampling bottle 50 and the discharge port of the lower hopper 30 being misaligned, so as to prevent the sample from falling out of the sampling bottle 50 during the unloading process.

[0036] In order to further limit the sliding of the sampling bottle 50 in the radial direction of the moving trajectory due to centrifugal force, along the set initial moving trajectory of the sampling bottle 50, a plurality of baffles 22 are provided on the upper surface of the floor of the filling chamber 20 around the central rotation axis of the sample bottle combing mechanism 11, and a delivery gap is formed between adjacent pairs of baffles 22 relative to the above-mentioned sample delivery port, and the delivery gap is connected to the sample bottle delivery port 21.

[0037] When the above device is used, the several baffles 22 arranged in an arc shape can limit the moving trajectory of the sampling bottle 50, and can limit the sampling bottle 50 to move along the circular trajectory within the circular area surrounded by the baffles 22; the conveying gap is at the initial position after the sampling bottle 50 is input into the sample bottle conveying port 21, which facilitates the sample bottle conveyor belt 40 to convey the sample bottle to the initial position or send it out of the sample bottle conveying port 21 from the initial position.

[0038] Furthermore, in order to ensure the sensitivity of the above-mentioned drive motor 112 in controlling the central rotating column 111 to rotate or stop rotating, so that the sampling bottle 50 can be accurately transported to the filling area or the initial area, the above-mentioned sample bottle combing mechanism 11 also includes a worm reducer 113. The end of the above-mentioned central rotating column 111 located below the floor of the filling chamber 20 is provided with a drive gear disc 1114, and the outer contour of the drive gear disc 1114 is provided with teeth. The housing of the worm reducer 113 is fixed on the frame 10 and is located between the drive motor 112 and the drive gear disc 1114. The output shaft of the worm reducer 113 is engaged with the drive gear disc 1114 through gears, and the input shaft of the worm reducer 113 is engaged with the output shaft of the drive motor 112 through gears.

[0039] When using the above device, after the drive motor 112 receives the start signal, it can drive the central rotating shaft to rotate at a lower speed through the worm reducer 113, so that the sampling bottle 50 moves smoothly along a circular trajectory; when the drive motor 112 receives the stop signal, it can quickly decelerate and brake through the worm reducer 113, so that the corresponding sampling bottle 50 reaches the predetermined position accurately, so as to prevent the sampling bottle 50 from moving too fast and being unable to stop quickly and align with the discharge port of the lower hopper 30 due to inertia, and to avoid the sampling bottle 50 being filled with the sample from spilling the sample due to inertia.

[0040] Furthermore, in order to realize the purpose of controlling the driving motor 112 in the above embodiment to achieve the purpose of accurately and orderly sorting the sampling bottles 50, the above-mentioned sample bottle weighing mechanism 12 includes an electronic scale 121 and a PLC controller 122, wherein the electronic scale 121 includes a weighing pan 1211 and a weighing sensor 1212, and the weighing pan 1211 is located just below the discharge port of the lower hopper 30 and embedded in the floor surface of the filling chamber 20, and the weighing pan 1211 and the upper surface of the bottom floor of the filling chamber 20 are at the same level; The weighing sensor 1212 is located at the bottom of the weighing pan 1211 and is connected to the frame 10. The weight sensing end of the weighing sensor 1212 abuts the lower surface of the weighing pan 1211. The signal output end of the weighing sensor 1212 is electrically connected to the PLC controller 122 and the drive motor 112 to form a control loop. The weighing sensor 1212 senses the empty weight and the weight after filling of the sampling bottle 50 to send information on whether the sampling bottle 50 has reached the filling area and whether the sampling bottle 50 is filled with a quantitative sample.

[0041] Specifically, a feeding control valve or a pneumatic sample feeding device is provided at one end of the lower hopper 30 away from its discharge port, and the above-mentioned PLC controller 122 also establishes a signal control relationship with the device. When the PLC controller 122 receives a signal that the empty sampling bottle 50 has arrived at the filling area, it immediately controls the drive motor 112 to stop driving, so that the sampling bottle 50 stays below the discharge port of the lower hopper 30, and then controls the lower hopper 30 to discharge according to the set discharge amount. When the filling amount reaches the set standard, the PLC controller 122 controls the lower hopper 30 to stop unloading, and then controls the drive motor 112 to drive the sampling bottle 50 to move along the preset trajectory, so that the sampling bottle 50 reaches the initial position and is output to the filling chamber 20 by the sample bottle conveyor belt 40.

[0042] Based on the structure of the above embodiment, the sample bottle weighing mechanism 12 is provided with an initial position sensor 23 on one side of the above-mentioned conveying gap in order to further control the sampling bottle 50 to move according to the set trajectory. The initial position sensor 23 includes a photoelectric object sensing sensor or an object proximity sensor. The initial position sensor 23 is connected to the above-mentioned PLC controller 122 signal and forms a cooperation. When the initial position sensor 23 senses that the empty sampling bottle 50 has arrived at the conveying gap, the information is fed back to form a control instruction to the drive motor 112, so that the sample bottle combing mechanism 11 starts to rotate; when the initial position sensor 23 senses that the filled sampling bottle 50 has arrived at the conveying gap, the information is fed back to form an instruction to the sample bottle conveyor belt 40, so that the sample bottle conveyor belt 40 conveys the sampling bottle 50 in the reverse direction and outputs the sample from the filling chamber 20.

[0043] Combined with the multiple structures and features in the above embodiments, the above sample filling and combing device can replace the manual sampling method, and compared with the existing technology, it can be more suitable for harsh mining environments, improve the efficiency of sample sampling and transportation, and greatly reduce labor costs.

[0044] Obviously, the above embodiments of the present application are merely examples for the purpose of clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those skilled in the art, other variations or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
