[0008] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0009] The star soil conveying and heating extraction device of the present invention is composed of three parts: a sealing drive module 1, a station conversion module 2, and a frame module 3.

[0010] The sealing drive module 1 drives the station conversion module 2 to move horizontally.

[0015] The U-shaped frame 2-2-1 is provided with a pair of bearings, and a pressure cover 2-2-14 is provided on the upper bearing for fixing the outer ring of the bearing. A dust cover 2-2-15 provided on the U-shaped frame 2-2-1 is used to prevent dust from the lower bearing 2-2-13.

[0016] One end of the sample holder 2-3-1 in the sample assembly 2-3 cooperates with the upper bearing, and the other end cooperates with the lower bearing 2-2-13 to form a rotating mechanism. The station conversion drive assembly 2-1 is installed on the U-shaped frame 2-2-1, and the station conversion shaft 2-1-6 is connected to the sample holder 2-3-1 through a key. When the station conversion drive assembly 2-1 rotates, the sample assembly 2-3 can be driven to rotate.

[0017] The sample assembly 2-3 includes a sample seat 2-3-1, a wire fixing seat 2-3-2, a scroll spring seat 2-3-3, a blocking cover 2-3-4, a sealing ring seat 2-3-5, a sealing ring 2-3-6, a gear 2-3-7, a sample holder 2-3-8, a Hall magnet 2-3-9, a temperature sensor 2-3-10, a bearing seat A2-3-11, a bearing A2-3-12, a bearing B2-3-13, a scroll spring shaft 2-3-14, a scroll spring 2-3-15, a needle rod 2-3-16, a rod seat 2-3-17, and a heating plate 2-3-18.

[0018] The sealing ring seat 2-3-5 is glued to the bearing seat A2-3-11. The bearing seat A2-3-11 is provided with a bearing A2-3-12, and the fixed bearing A2-3-12 is placed inside the blocking cover 2-3-4, and the blocking cover 2-3-4 is fixed to the volute spring seat 2-3-3 by screws.

[0019] A spiral spring 2-3-15 is arranged between the spiral spring seat 2-3-3 and the spiral spring shaft 2-3-14, one end of the spiral spring 2-3-15 is fixed on 2-3-14, and the other end is fixed on the spiral spring seat 2-3-3. A bearing B2-3-13 is arranged between the spiral spring shaft 2-3-14 and the sample seat 2-3-1.

[0020] The scroll spring seat 2-3-3 is fixed on the sample seat 2-3-1, thereby the sealing ring seat 2-3-5, the bearing seat A2-3-11, the fixed bearing A2-3-12, the blocking cover 2-3-4, the scroll spring seat 2-3-3, the sample seat 2-3-1, the bearing B2-3-13, and the scroll spring shaft 2-3-14 will form a rotating system.

[0021] A gear 2-3-7 is provided at the end of the sealing ring seat 2-3-5, and the gear 2-3-7 is fixed at the end of the sealing ring seat 2-3-5. When a torque is applied to the gear 2-3-7, the sealing ring seat 2-3-5 will rotate along with the bearing A2-3-12 and the bearing B2-3-13. After rotating a certain angle, the spiral spring 2-3-15 will accumulate force. After releasing the torque applied to the gear 2-3-7, the spiral spring 2-3-15 will rebound quickly, so that the sealing ring seat 2-3-5 will rebound quickly to the original position.

[0022] Four rod holders 2-3-17 are arranged on the sealing ring holder 2-3-5, and four needle rods 2-3-16 are arranged on the rod holder 2-3-17. The rod holder 2-3-17 is sintered on the sealing ring holder 2-3-5 and the needle rods 2-3-16. The four needle rods 2-3-16 are connected to the sample holder 2-3-8. A temperature sensor 2-3-10 is arranged at the tail of the sample holder 2-3-8 to measure the temperature of the sample holder 2-3-8. The two upper needle rods 2-3-16 are connected to the two wires of the temperature sensor 2-3-10, and the two lower needle rods 2-3-16 are connected to the two wires of the heating plate 2-3-18 arranged on the surface of the sample holder to heat the sample holder 2-3-8.

[0023] When the sealing ring seat 2-3-5 rotates, the sample holder 2-3-8 is driven to rotate. A Hall magnet 2-3-9 is provided on the sample seat 2-3-1 to control the rotation angle of the sample assembly 2-3. A wire fixing seat 2-3-2 is provided on the sample seat 2-3-1 to fix the wires led out from the needle bar 2-3-16. The right side of the sample assembly 2-3 is completely symmetrical with the left side, and the parts used are exactly the same.

[0024] The frame module 3 includes a frame 3-1, an exhaust pipe 3-2, a guide rod A 3-3, a linear potentiometer 3-4, a funnel 3-6, a rack 3-7, a guide rod B 3-8, a furnace 3-9, a strain gauge 3-10, a scraper 3-11, and a cover plate 3-12.

[0025] The U-shaped frame assembly 2-2 cooperates with the guide rod A3-3 and the guide rod B3-8 provided on the frame module 3 through a pair of sliders to form a sliding friction pair. Polytetrafluoroethylene scraper pads A2-2-3, polytetrafluoroethylene scraper pads B2-2-4, polytetrafluoroethylene scraper pads C2-2-5 and polytetrafluoroethylene scraper pads D2-2-6 are provided at both ends of the pair of sliders to protect the pair of sliders and prevent dust from entering the sliding friction pair.

[0026] The sealing drive module 1 is installed on the U-shaped frame 2-2-1 of the frame module 3. The sealing screw 1-5 on the sealing drive module 1 cooperates with the trapezoidal nut 2-2-2 to form a screw pair. When the sealing screw 1-5 of the sealing drive module 1 rotates, the trapezoidal nut 2-2-2 is driven to move, thereby driving the station conversion module 2 to move. The linear potentiometer 3-4 cooperates with the linear potentiometer shaft 2-2-7 to monitor the moving distance of the station conversion module 2 in real time.

[0027] When the station conversion module 2 is in the rotating position, the station conversion module 2 is driven to move toward the sample receiving position by the rotation of the sealing drive module 1. When the linear potentiometer 3-4 detects that the station conversion module 2 has moved to the sample receiving position and the micro switch 3-5 is in contact with the linear potentiometer bracket 2-2-8, the sealing drive module 1 stops rotating, the station conversion module 2 is in the sample receiving position, and an external device (such as a manipulator) delivers samples to the sample holder 2-3-8 through the funnel 3-6.

[0028] Then the sealing drive module 1 rotates in the opposite direction to move the station conversion module 2 in the opposite direction. When the sample holder 2-3-8 moves to the position of the scraper 3-16, the scraper 3-16 can shape the sample in the sample holder 2-3-8 to facilitate subsequent heating.

[0029] When the linear potentiometer 3-4 set on the station conversion module 2 detects that the station conversion module 2 moves to the set distance, and when the strain gauge 3-14 detects that the sealing ring seat 2-3-5 on the station conversion module 2 contacts the furnace 3-9 to generate the set stress, the sealing drive module 1 stops rotating, so that the station conversion module 2 stops moving. At this time, the sample holder 2-3-8 heats the sample to volatilize the components of the sample and transport it to the detection equipment through the exhaust pipe 3-2. The heating time and temperature are set according to needs, the time is usually 10min-30 min, and the heating temperature is ≤300℃.

[0030] After the heating is completed, the sealing drive module 1 rotates to move the station conversion module 2 in the sample receiving direction. When the linear potentiometer 3-4 detects that the station conversion module 2 moves to the rotation position, the sealing drive module 1 stops rotating, and the station conversion module 2 stops moving. At this time, the station conversion drive component 2-1 in the station conversion module 2 starts to rotate, thereby driving the sample component 2-3 to rotate horizontally. When the encoder 2-1-3 detects that the sample component 2-3 rotates to the sample discarding position (rotated 90°), the station conversion drive component 2-1 stops rotating, and the sample component 2-3 stops rotating.

[0031] At this time, the sealing drive module 1 starts to drive the station conversion module 2 to move toward the sealing position. When the gear 2-3-7 on the sample assembly 2-3 moves to engage with the rack 3-7 of the frame module 3, the movement of the gear 2-3-7 can drive the sample holder 2-3-8 on the sealing ring seat 2-3-5 to flip 180° to achieve sample discard. After sample discard, the sealing drive module 1 moves in the opposite direction until the station conversion module 2 is in the rotating position again. A working cycle is completed. Cover plates 3-12 are provided on both sides and the top surface of the frame module to protect the station conversion module 2.

[0032] The sample holder on the right side of the sample assembly 2-3 is used alternately with the sample holder on the left side, so that when one sample holder is heated, the other sample holder is in a heat dissipation cooling state, thereby enabling uninterrupted sampling and reducing the cooling interval time.

[0033] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
