[0024] This embodiment discloses a coal detection and extraction device with heating function, such as... Figure 1-4 As shown, the device includes a support frame 1, a lifting platform 6 slidably mounted on the upper side of the support frame 1, lifting components installed on the upper and lower sides of the lifting platform 6 for adjusting the position of the lifting platform 6 on the upper and lower sides of the support frame 1, a hollow sampling cylinder fixedly mounted on the lifting platform 6, a hollow conveying cylinder fixedly connected to the lower side of the sampling cylinder, a spiral conveying rod rotatably mounted inside the conveying cylinder, the upper side of the spiral conveying rod passing through the top of the lifting platform 6 and rotatably mounted with the lifting platform 6, a drive motor 3 connected to the upper side of the spiral conveying rod, and the drive motor 3 fixedly mounted with the lifting platform 6. By mounting the support frame 1 on a gantry crane, the lateral movement of the support frame 1 is facilitated. An auxiliary support rod 9 is fixedly mounted on the support frame 1, which has an auxiliary support function and improves the stability of the device during operation.
[0025] The lifting component includes a power motor 2 fixedly installed on the lower side of the support 1. The output end of the power motor 2 is connected to the support 1 through a bearing seat 16. A lower sprocket is fixedly installed on the output end of the power motor 2. A transmission shaft is connected to the top of the support 1 through the bearing seat 16. An upper sprocket is fixedly connected to the middle side of the transmission shaft. A chain 7 with its head and tail connected is connected to the upper sprocket and the lower sprocket. The head and tail ends of the chain 7 are fixedly set to the upper and lower sides of the lifting platform 6, respectively. When the power motor 2 is turned on, the power motor 2 drives the chain 7 to rotate, thereby driving the lifting platform 6 to move freely along the upper and lower sides of the support 1 through the chain 7.
[0026] The spiral conveyor includes an upper spiral rod 10 and a lower spiral rod 11, which are fixedly arranged.
[0027] The upper end of the upper screw rod 10 is rotatably mounted on the upper side of the lifting platform 6. The outer diameter of the lower screw rod 11 is larger than the outer diameter of the upper screw rod 10. The lower part of the lower screw rod 11 has multiple evenly distributed sawtooth grooves 14. The sawtooth grooves 14 at this location help reduce the resistance when collecting coal samples and also increase the crushing effect.
[0028] The conveying cylinder includes an upper conveying pipe 8 and a lower conveying pipe 12. The upper conveying pipe 8 and the lower conveying pipe 12 are welded and fixedly connected. The diameter of the lower conveying pipe 12 is larger than the diameter of the upper conveying pipe 8, which facilitates the lower screw rod 11 to be located inside the lower conveying pipe 12 and the upper screw rod 10 to be located inside the upper conveying pipe 8, thereby facilitating the collection of coal samples through the lower screw rod 11.
[0029] The sampling cylinder includes a straight cylinder 5 and a conical cylinder 15, which are rotatably mounted. An upper flange is fixedly connected to the lower side of the conical cylinder 15, and a lower flange is fixedly connected to the upper side of the upper conveying pipe 8. The upper and lower flanges are fixedly mounted by locking bolts and locking nuts. A sealing gasket is installed between the upper and lower flanges. An external gear 17 is fixedly connected to the outside of the straight cylinder 5. The external gear 17 is meshed with a small gear. A cleaning motor is fixedly mounted on one side of the lifting platform 6. The output end of the cleaning motor is fixedly mounted to the small gear. The cleaning motor drives the small gear to rotate, which in turn drives the straight cylinder 5 to rotate through the external gear 17, injecting water into the straight cylinder 5, thus facilitating the cleaning of the inside of the straight cylinder 5. The sealing gasket here has a sealing function. A lower plate 4 is connected to the lower side of the lifting platform 6 by a screw and nut. The lower plate 4 is fixedly mounted to the conical cylinder 15. The lower plate 4 facilitates the removal of the conical cylinder 15 from the lifting platform 6.
[0030] The bracket 1 has symmetrical grooves, and the lifting platform 6 has protrusions that match the grooves. The protrusions are inserted into the corresponding grooves, which allows the lifting platform 6 to move freely along the upper and lower sides of the bracket 1.
[0031] A ring-shaped ceramic electric heater is installed at the bottom of the lower flange. The ceramic electric heater is fitted on the outside of the upper conveying pipe 8. This ceramic electric heater is existing technology and will not be described in detail here. It mainly heats the upper conveying pipe 8, thereby reducing the phenomenon of the spiral conveying rod freezing due to moisture in winter.
[0032] The lower conveying pipe 12 has multiple chamfered openings 13 on its lower side, which facilitate the lower conveying pipe 12 entering the loading hopper of the coal vehicle.
[0033] In use, the device is first installed on a gantry crane, the lateral position of the support 1 is adjusted, and the conveying cylinder is positioned on the upper side of the coal-filled truck bed. Then, the power motor 2 is turned on, which drives the chain 7 to work, thereby changing the position of the lifting platform 6 on the upper and lower sides of the support 1. After the lifting platform 6 drives the lower conveying pipe 12 to be inserted into the coal pile, the drive motor 3 is turned on, which drives the screw conveyor to rotate, thus facilitating the delivery of coal to the sampling cylinder, thereby completing the sampling of coal from the truck bed.
