Detailed Implementation

[0033] like Figure 1 As shown, an intelligent closed-type sample collection bucket includes a sample bucket 1 and an intelligent sealing cover 2. The intelligent sealing cover 2 and the sample bucket 1 will separate and close when collecting coal samples.

[0034] like Figure 2 and Figure 5 As shown, the sample container 1 includes an integrally connected neck 101 and body 102. Two novel arc-shaped handles 103 are symmetrically arranged on the neck 101. Each arc-shaped handle 103 includes a connecting plate 1031 and an arc-shaped steel pipe 1032. The connecting plate 1031 is fixed to the neck 101, and both ends of the arc-shaped steel pipe 1032 are welded to the connecting plate 1031. The arc length of the arc-shaped steel pipe 1032 is greater than or equal to one-quarter of its circumference and less than or equal to one-half of its circumference. The length of the arc-shaped steel pipe 1032 can be set according to the volume of the sample container 1. When the volume is large, i.e., when the sample container 1 (containing coal samples) is heavy, the length of the arc-shaped steel pipe can be set longer. When the length of the arc-shaped steel pipe 1032 is one-half of its circumference, the two novel arc-shaped handles 103 form a single, integrated ring handle.

[0035] Traditional double-eared handles are typically fixed to both ends of the sample collection container, with handle dimensions limited to a single-handed grip and an excessively thin diameter. Since the sample collection container, once filled, usually weighs over ten kilograms, removing it from the sample collector can be quite strenuous. However, the curved steel pipe 1032 of this invention is longer, making it easier to grasp. The steel pipe has a diameter of 25mm and an curved design, allowing for a secure grip when handling the container, preventing hand injury and slippage. Furthermore, the longer curved surface of the handle increases the ease of finding the handle regardless of the sample container's placement angle.

[0036] like Figure 3 As shown, an annular locking band 104 is provided on the inner side of the neck 101. The locking band 104 is an annular boss. An annular inclined surface is provided on the inner side of the edge of the neck 101, and the shape is a trumpet mouth.

[0037] As shown in Figures 6-11 The smart sealing cover 2 includes a cover body clamping handle 201, a cover 202, a locking compartment 203 and a locking device. Specifically, the cover body clamping handle 201 includes a limiting boss 2011 and a clamping column 2012, the upper part of the clamping column is fixedly connected with the limiting boss 2011, and the lower part is fixedly connected with the middle of the cover 202. The cover body clamping handle 201 is used for automatic opening and closing of the sample collector, the mechanical hand clamps the clamping column 2012, and then moves upward, so as to separate the smart sealing cover 2 from the sample barrel 1; when the sample barrel 1 is full of coal samples, the mechanical hand clamps the clamping column 2012 to close the smart sealing cover 2 and the sample barrel 1.

[0038] The locking compartment 203 is installed below the cover 202, which is a cylindrical cavity with an open bottom and is sealed by a compartment cover 204.

[0039] The locking device includes an electromagnetic lock 205, a controller 206, an RFID card reader 208 and a charging lithium battery 207, wherein the electromagnetic lock 205, the controller 206 and the charging lithium battery 207 are installed in the locking compartment 203 on the bottom surface of the cover 202, the RFID card reader 208 is installed in the middle of the limiting boss 2011, a square slot is formed in the middle of the limiting boss 2011, and the RFID card reader 208 is placed in the square slot. The RFID card reader 208 is installed in the middle of the limiting boss 2011, which can facilitate the operator to scan the code from all directions. An electric quantity display 209 and a charging port 210 are installed on the upper surface of the cover 202. The controller 206 is electrically connected with the electromagnetic lock 205 and the RFID card reader 208 through cables, and a wire hole is arranged in the clamping column 2012. The charging lithium battery 207 is electrically connected with the controller 206, the charging port 210 and the electric quantity display 209. The electromagnetic lock 205, the controller 206 and the charging lithium battery 207 are installed on the bottom surface of the cover 202, which is stable and convenient for wiring.

[0040] The electromagnetic lock 205 is two, mirror installation, the electromagnetic lock 205 includes a lock tongue 2051, and lock tongue outlets are arranged on both sides of the compartment wall of the locking compartment 203 for extension and retraction of the lock tongue 2051.

[0041] As shown in Figure 5 An identification chip (not shown in the figure) for identifying the sample barrel 1 is arranged on the inner recess area.

[0042] As shown in Figure 10As shown, the electromagnetic lock 205 further comprises an electromagnetic coil 2052, a spring 2053 and a placing frame 2054, the latch bolt 2051, the electromagnetic coil 2052 and the spring 2053 are all installed in the placing frame 2054, the spring 2053 is located in the inner cavity of the electromagnetic coil 2052, and a part of the latch bolt 2051 is located in the inner cavity of the electromagnetic coil 2052, and the tail end of the latch bolt 2051 is in contact with the spring 2053.

[0043] Specifically, the inner side of the upper edge of the sample barrel 1 is provided with an annular slope 105, and the head of the latch bolt 2051 is cut into a bevel 20511, and the inclination angle of the bevel 20511 is equal to the inclination angle of the annular slope 105. The latch bolt 2051 is made of stainless steel.

[0044] The telescopic principle of the electromagnetic lock 205 is that when the electromagnetic coil 2052 is not powered, the spring 2053 is connected with the latch bolt 2051 freely; when the electromagnetic coil 2052 is powered, the power generates an electromagnetic force to drive the latch bolt 2051 to move towards the spring 2053, and the spring 2053 is compressed; when the electromagnetic coil 2052 is powered off, the spring 2053 releases the elastic force and restores the original extended state with the latch bolt 2051 due to the absence of the electromagnetic force.

[0045] When the electromagnetic coil 2052 is not powered, the latch bolt 2051 is in the original extended state, that is, when an external force pushes the latch bolt 2051 towards the spring 2053, the latch bolt 2051 can be freely retracted, and when the external force disappears, the latch bolt 2051 automatically extends. When the intelligent sealing cover 2 is placed on the upper opening of the sample barrel 1, the cylindrical locking chamber 203 descends along the barrel opening due to the external force from above and the weight, at this time, the exposed end of the latch bolt 2051 is in contact with the annular slope 105 of the lock hoop, and the annular slope 105 will gradually push the latch bolt 2051 into the locking chamber 203, when running to the lower part of the lock hoop 104, the latch bolt 2051 slides to the end of the lock hoop 104 without obstruction, the spring 2053 in the electromagnetic lock restores, the latch bolt 2051 freely pops out and generates a barrier with the lock hoop 104, and the bottom of the edge of the cover 202 is in contact with the barrel opening, so that the intelligent sealing cover 2 is automatically locked with the sample barrel 1.

[0046] Please combine Figure 11 , the controller 206 controls the on-off of the two electromagnetic locks 205, the RFID card reader 208 reads the information on the RFID radio frequency card, verifies the legality, sends the information to the controller 206, and controls the two electromagnetic locks 205 to be powered on at the same time, so that the two latch bolts 2051 are retracted at the same time, and the intelligent sealing cover 2 and the sample barrel 1 are unlocked.

[0047] The controller 206 is made of an ATMEGA single-chip microcomputer. The RFID technology is a mature technology, and its principle is not described here.

[0048] Compared with the electric plug lock in the prior art, the utility model discloses an electromagnetic lock 205, on the one hand, when closing, no power operation is needed, only when unlocking is used, and the electric plug lock needs power operation to drive the gear rotation, and the opening and closing of the cover need power operation, and because the structure is relatively complex, the power operation process is twice of the utility model, and because the coal sample collection needs continuous operation, the unlocking and locking work under high load, and therefore, the failure rate is relatively large.

[0049] In conclusion, the utility model discloses that RFID card swiping is used to control the electromagnetic lock 205, and the operation is simple and convenient, and the novel arc-shaped handle is suitable for the working process of taking and placing the barrel, and the risk of hand release is small, and in addition, the power-off delay is arranged in the controller 206, the electromagnetic coil 2052 can be powered off in 0-60 seconds, thereby releasing the lock tongue 2051 and making it return to the free state.

[0050] The above has made the detailed description to the embodiment of the utility model in combination with the drawings, but the utility model is not limited to this, and all the various changes that can be made within the cognitive range of the technical personnel in the technical field to which the utility model belongs without departing from the purpose of the utility model are within the protection scope of the utility model claim.
