Description

Technical Field

[0001] The invention relates to an automatic stone sampling device and a use method thereof, belonging to the technical field of sampling. Background Art

[0002] As an important industrial raw material, limestone plays an irreplaceable role in cement manufacturing, metallurgical industry, environmental protection desulfurization and other fields. Its quality parameters (CaO content, MgO content, particle size distribution, etc.) directly affect the quality of the final product and the stability of the production process.

[0003] The current industry generally adopts the manual sampling method after the transport vehicle unloads, which has the following three core problems:

[0004] 1) Insufficient sampling representativeness: Manual sampling is significantly affected by subjective factors. Operators can only collect samples at a depth of 0.3-0.5 meters on the surface of the pile, and the sampling depth is obviously limited. At the same time, only 3-5 sampling points are selected in routine operations, and continuous sampling of the entire unloading process cannot be achieved, resulting in a single batch of samples being difficult to accurately reflect the overall quality of the material;

[0005] 2) Data reliability risk: There are risks of fraud such as sample replacement and artificial tampering of test data;

[0006] 3) Occupational health hazards: The dust pollution generated during the unloading process is serious, and the high-dust working environment poses a direct threat to the respiratory health of the sampling personnel;

[0007] It should be pointed out that the existing limestone sampling is mainly aimed at sampling scenarios of static materials in storage tanks, such as: "Automatic continuous sampling device for limestone" disclosed by patent number CN217930953U, "Automatic sampling device for limestone powder in coal-fired power plants" disclosed by patent number JP3247286U, etc. At present, no automated sampling equipment specifically for the dynamic unloading process of transport vehicles has been developed.

Figure 3 , Figure 5As shown, the transverse movement assembly 4 includes a box body 41, a drive, a reel 42, a track strip 43, a dust cover 44 and a support rod 45; the box body 41 is fixed to the ground, and a reel 42 and a drive are arranged in each box body 41. The reel 42 is driven to rotate by a one-to-one corresponding drive, and the two ends of the track strip 43 are respectively wound around the outer side walls of the two groups of reels 42 on the same side; the track strip 43 is composed of track plates hinged head to tail in sequence, which not only has a certain rigidity but also does not hinder winding around the outer side wall of the reel 42; the dust cover 44 is arranged between the two groups of box bodies 41 on the same side, and the track strip 43 between the two groups of box bodies 41 moves in the dust cover 44, and the dust cover 44 is used to prevent the transport vehicle 1 from accumulating on the track strip 43 during the process of unloading limestone; an avoidance groove is opened on the bottom wall of the dust cover 44, and the width of the avoidance groove is smaller than the width of the track strip 43, and support rods 45 are fixedly arranged on both sides of the avoidance groove, and the track strip 43 is relatively placed on the upper surface of the two groups of support rods 4.

[0066] The two groups of reels 42 on the same side wind up or release the track strips 43 thereon, thereby driving one end of the sampling assembly 5 to move horizontally and linearly.

[0067] like Figure 8 As shown, the sampling assembly 5 includes a supporting shell 51, a material collection barrel 52 and a rotator 53; the material collection barrel 52 is horizontally arranged and both ends are rotatably connected to the two groups of supporting shells 5, and a rotator 53 is installed in the supporting shell 51, and the material collection barrel 52 is driven to rotate by the rotator 53; a horizontally extending opening is opened on one side of the material collection barrel 52, and the rotation of the material collection barrel 52 realizes that its opening faces upward or downward.

[0068] like Figure 5-Figure 7 As shown, the elastic telescopic rod 10 can adjust its length and tends to shorten under normal conditions.

[0069] like Figure 2 , Figure 4 As shown, a blocking component 6 is provided on one side of the non-transverse moving component 4 of the grille mesh 3, and the output end of the transmission component 7 is just connected to this side; the blocking component includes a lifting device 61 and a baffle 62, and the lifting device 61 can adopt a hydraulic telescopic cylinder, and the lifting device 61 is used to drive the baffle 62 to lift vertically.

[0070] The transmission assembly 7 includes a first conveyor 71 and a second conveyor 72 arranged on one side of the grid net 3. Under normal circumstances, the first conveyor 71 and the grid net 3 are separated by a baffle 62 to prevent limestone from entering the first conveyor 71 during limestone unloading. The input end of the second conveyor 72 is connected to the output end of the first conveyor 71, and a hopper 73 is provided at the output end of the second conveyor 72.

[0071] like Figure 12-13 As shown, the sampling barrel 9 includes a barrel body 91, the top wall and the bottom wall of the barrel body 91 are designed to be open, and the upper barrel cover 92 and the lower barrel cover 93 are both linearly slidably connected to the barrel body 91. The upper barrel cover 92 slides on the upper part of the barrel body 91 to open or close the top wall opening of the barrel body 91, and the lower barrel cover 93 slides on the lower part of the barrel body 91 to open or close the bottom wall opening of the barrel body 91. The upper barrel cover 92 and the lower barrel cover 93 are both provided with corresponding lock buckles 941, and the upper and lower parts of the barrel body 91 are both installed with electronic locks 94. When the upper barrel cover 92 closes the top wall opening of the barrel body 91, its lock buckle 941 is just inserted into the electronic lock 94. The lock buckle 941 of the lower barrel cover 93 is the same as the corresponding electronic lock 94.

[0072] like Figure 9-11 , Figure 14-16 As shown, the barrel changing assembly 8 includes a conveyor belt assembly 801, a platform 802, a side guard plate 81, a first moving module 82, a first magnetic member 83, an unlocker 85, a second moving module 86, a second magnetic member 87, a barrel rack 88, a third moving module 89, an oblique push block 891 and a railing 892;

[0073] One side of the barrel rack 88 is opened to facilitate observation of the sampling barrel 9 therein, and the opening is provided with a plurality of magnetic suction doors from top to bottom for opening and closing;

[0074] The first moving module 82, the second moving module 86 and the third moving module 89 can be electric telescopic rods or telescopic cylinders or hydraulic telescopic cylinders, etc.; the first magnetic member 83 and the second magnetic member 87 can be electromagnets or permanent magnets, the upper barrel cover 92 is magnetically matched with the first magnetic member 83, and the lower barrel cover 93 is magnetically matched with the second magnetic member 87;

[0075] The conveyor belt assembly 801 is arranged horizontally and has side guard plates 81 on both sides, and the platform 802 is arranged horizontally at the input end of the conveyor belt assembly 801;

[0076] The hopper 73 at the output end of the second conveyor 72 is aligned with the conveyor belt assembly 801, and an unlocker 85 and a first moving module 82 are provided at this position, and a first magnetic member 83 is installed at the output end of the first moving module 82;

[0077] The barrel rack 88 is vertically arranged just above one end of the platform 802 close to the conveyor belt assembly 801, and the inner cavity of the barrel rack 88 is adapted to the sampling barrel 9 so that the sampling barrel 9 is stacked up and down in the barrel rack 88; the platform 802 is provided with a discharge hole 811 located just below the barrel rack 88, and the diameter of the discharge hole 811 is smaller than the sampling barrel 9 to prevent the sampling barrel 9 from passing through, and the second movable module 86 and the unlocker 85 are respectively arranged on the opposite sides of the platform 802 with the discharge hole 811, and the output end of the second movable module 86 is provided with a second magnetic member 87; an avoidance space is reserved between the bottom wall of the barrel rack 88 and the top wall of the platform 802, and the height of the avoidance space is just enough for a group of sampling barrels 9 to move horizontally;

[0078] An oblique push block 891 is installed at the output end of the third movable module 89. The inclined surface of the oblique push block 891 is located on the side close to the barrel rack 88, and a railing 892 is hinged at the lower end of the inclined surface. The railing 892 is kept in a vertical state by a torsion spring under normal conditions.

[0079] Working principle:

[0080] When the transport vehicle 1 moves to the grille 3, the automatic control system (or manual) detects that the transport vehicle 1 needs to unload stones, and controls the two groups of transverse movement components 4 to move randomly within a set range, thereby controlling the sampling components 5 to be parallel or inclined relative to the baffle 62. When the sampling components 5 are inclined relative to the baffle 62, the elastic telescopic rod 10 is extended and retracted for compensation.

[0081] The movement distances of the two groups of transverse moving components 4 are L1 and L2 respectively. The movement of the transverse moving components 4 can also be manually controlled according to the needs, so that the sampling component 5 can be moved to the set position and angle relative to the transport vehicle 1, thereby realizing sampling at a special position. The moving distances L1 and L2 of the transverse moving components 4 can be the same or different. If L1 and L2 are different at the same time, sampling with a larger span can be realized, thereby enhancing the representativeness of the sample.

[0082] When the transport vehicle 1 unloads the limestone, the timing starts, the visual recognition camera in the automatic control system identifies the remaining stone in the vehicle, and randomly selects a time point between the start of unloading and the end of unloading. The rotator 53 in the sampling assembly 5 drives the material collection bucket 52 to rotate so that its opening faces upward. The rotator 53 is started by a random algorithm control within the set time, thereby driving the material collection bucket 52 to rotate, so that the opening of the material collection bucket 52 rotates from bottom to top. The material collection bucket 52 with the opening facing upward can collect the limestone unloaded from the transport vehicle 1.

[0083] If the unloading is too violent, when the opening of the material taking bucket 52 rotates to the top, it will be pressed onto the grille net 3, and the elastic telescopic rod 10 cannot be pulled after being stretched, and is supported by the grille net 3 at this time.

[0084] The rotator 53 can also be manually controlled as required.

[0085] After the transport vehicle 1 completes unloading of the limestone, the lifting device 61 drives the baffle 62 to rise vertically, so that the bottom of the baffle 62 is hollowed out to form a space for the sampling component 5 to pass horizontally. The two sets of transverse movement components 4 cooperate to drive the sampling component 5 (the material bucket 52 with the opening facing upward and filled with sampled limestone) to move horizontally to the upper surface of the first conveyor 71. Then the material bucket 5 rotates in the opposite direction so that the opening faces downward, so that the limestone therein falls onto the upper surface of the first conveyor 71.

[0086] Afterwards, the limestone is transported to the sampling barrel 9 through the first conveyor 71 , the second conveyor 72 and the hopper 73 in sequence.

[0087] After the sampling barrel 9 is filled with limestone, the opening of the top wall is controlled to be closed and the sample barrel 9 is transported outwards through the conveyor belt assembly 801 , and at the same time, another group of subsequent sample barrels 9 are transported to the bottom of the hopper 73 .

[0088] The third movable module 89 extends and drives the oblique push block 891 to move to the bottom of the barrel rack 88. During this process, the railing 892 remains in a vertical state, which is conducive to pushing the sampling barrel 9 in the avoidance space below the barrel rack 88 to move to the conveyor belt assembly 801; then the third movable module 89 shortens and drives the oblique push block 891 to reset. During this process, the lowest group of sampling barrels 9 in the barrel rack 88 slowly slides down to the avoidance space below the barrel rack 88 under the action of the inclined surface of the oblique push block 891, and the railing 892 is pressed to a horizontal state by the sampling barrel 9. The horizontal railing 892 can be pulled out from under the sampling barrel 9, and the horizontal railing 892 is reset under the action of the torsion spring after it detaches from the sampling barrel 9.

[0089] The sampling barrel 9 falls from the barrel rack 88 to the avoidance space below, and the electronic lock 94 corresponding to the lower barrel cover 93 just moves to the unlocker 85 corresponding to the platform 802. The unlocker 85 controls the electronic lock 94 to unlock (this is a prior art and will not be described in detail), and the lock buckle 941 can be disengaged from the electronic lock 94, and then the second moving module 86 is controlled to drive the second magnetic member 87 away from the platform 802. Since the second magnetic member 87 and the lower barrel cover 93 are magnetically attracted to each other and move together, the lower barrel cover 93 opens the bottom wall opening of the barrel body 91, and the bottom wall opening of the barrel body 91 can lead out the components inside and pour them downward through the discharge hole 811; this design can prevent the sampling accuracy from being affected by the limestone being loaded into the sampling barrel 9 in advance. Afterwards, the second moving module 86 drives the second magnetic member 87 to reset close to the platform 802, so that the lower barrel cover 93 closes the bottom wall opening of the barrel body 91 again, and the lock buckle 941 is inserted into the electronic lock 94, and then the unlocker 85 controls the electronic lock 94 to lock.

[0090] When the sampling barrel 9 moves to the conveyor belt assembly 801 and is located below the hopper 73, the electronic lock 94 corresponding to the upper barrel cover 92 just moves to the unlocker 85 corresponding to the hopper 73, and the unlocker 85 controls the electronic lock 94 to unlock, and the lock buckle 941 can be disengaged from the electronic lock 94, and then the first moving module 82 is controlled to drive the first magnetic member 83 away from the conveyor belt assembly 801. Since the first magnetic member 83 and the upper barrel cover 92 are magnetically attracted to each other and move together, the upper barrel cover 92 opens the top wall opening of the barrel body 91, and the top wall opening of the barrel body 91 can load the limestone poured out from the bottom of the hopper 73 into it;

[0091] After all the limestone is loaded into the barrel body 91, the first movable module 82 drives the first magnetic member 83 to reset close to the conveyor belt assembly 801, so that the upper barrel cover 92 recloses the opening of the top wall of the barrel body 91, and the lock buckle 941 is inserted into the electronic lock 94, and then the unlocker 85 controls the electronic lock 94 to lock.
