[0029] like Figures 1-4As shown, a remote operation control system of a screw ship unloader includes: a vertical screw assembly and a remote intelligent controller 5. The vertical screw assembly includes a vertical spiral pipe 1 and a reclaiming head 2. The vertical screw assembly is a common component in a screw ship unloader and is used to transfer materials in the cabin to a designated location. It is a prior art and the specific structure and working principle of the present application will not be described in detail. The vertical spiral pipe 1 and the reclaiming head 2 are staggered. The top port of the reclaiming head 2 is rotatably connected to a transverse pipe 3. The logistics in the cabin are broken up by the rotation of the reclaiming head 2, and are transported to the transverse pipe 3 along with the bottom of the reclaiming head 2, and then transferred to the vertical spiral pipe 1 to unload the materials and pass through the vertical spiral pipe 1 and the reclaiming head 2 are provided with a two-stage structure to reduce the pressure of the material on the auger when it moves vertically upward. The other end of the transverse tube 3 is rotatably connected to the bottom port of the vertical spiral tube 1. A deflection control component 6 is installed on the vertical spiral tube 1. The output end of the deflection control component 6 is connected to the transverse tube 3 to drive the transverse tube 3 to rotate around the axis of the vertical spiral tube 1. When the transverse tube 3 is deflected, the reclaiming head 2 at the end will be driven to rotate around the axis of the vertical spiral tube 1, thereby adjusting the position of the reclaiming head 2, thereby adjusting the position of the feed port of the reclaiming head 2. When targeting positions such as the edge of the cabin, the reclaiming head 2 is adjusted to be close to the edge of the cabin, reducing unloading dead angles and improving unloading efficiency.

[0030] It is worth mentioning that Figure 4 、 Figure 5 and Figure 8 As shown, a feeding detection chamber 11 is installed at the position corresponding to the top port of the transverse tube 3 and the feeding head 2, a sealing pressure plate 22 is provided between the top of the inner cavity of the feeding head 2 and the inner cavity of the feeding detection chamber 11, and an air pressure sensor 21 is installed in the inner cavity of the feeding detection chamber 11 for detecting the air pressure value of the cavity formed by the sealing pressure plate 22 and the inner cavity of the feeding detection chamber 11. When the feeding head 2 conveys the material normally, the material enters the feeding head 2 from bottom to top. At this time, the material will squeeze the sealing pressure plate 22 on the top of the feeding head 2 and compress the cavity above the sealing pressure plate 22, thereby changing the air pressure value of the cavity where the sealing pressure plate 22 is located. When the feeding auger 17 is in idling, as shown in FIG. Figure 8 At this time, the squeezing force of the material on the sealing pressure plate 22 is reduced, and the air pressure value of the chamber where the sealing pressure plate 22 is located is also reduced. Therefore, it is possible to flexibly detect whether the material head 2 is idling, which is convenient for remote control of the screw unloader.

[0031] Also, see Figure 6The remote intelligent controller 5 is provided with a remote data transmission module, a detection and analysis module, an idling processing module and a reminder module. The remote data transmission module is respectively connected to the air pressure sensor 21 and the deflection control component 6 by wireless transmission. The remote data transmission module is connected to the detection and analysis module by signal. The detection and analysis module is respectively connected to the reminder module and the idling processing module by signal. When the screw unloader is working to unload the materials in the cabin, the materials enter through the bottom of the reclaiming head 2 and enter the vertical spiral tube 1 through the horizontal pipe 3. In this process, the air pressure sensor 21 will detect The measured air pressure value is wirelessly transmitted to the detection and analysis module in real time through the remote data transmission module. The detection and analysis module sends the air pressure value of the air pressure sensor 21 to the idling processing module for processing. The idling processing module compares the air pressure value fed back by the air pressure sensor 21 with the preset normal air pressure value (the idling processing module is preset with the normal air pressure value of the chamber where the air pressure sensor 21 is located when the material head 2 is unloading normally). When the idling processing module determines that the air pressure value fed back by the air pressure sensor 21 is less than the preset normal air pressure value, it is determined that the material head 2 is in an idling state. At this time, the material is compacted or has a problem with the material. When the material head 2 is out of contact, the idling processing module sends the judgment result to the detection and analysis module, and the detection and analysis module sends a reminder signal to the reminder module. The reminder module reminds the operator of the handheld remote intelligent controller 5 that the material head 2 is in an idling state through light and sound, so that the operator can timely understand the working status of the material head 2; at the same time, the detection and analysis module wirelessly controls the deflection control component 6 through the remote data transmission module. The deflection control component 6 will control the material head 2 to deflect, thereby automatically adjusting the position of the material head 2 until the material head 2 discharges the material normally. At this time, the idling processing module determines that the air pressure value feedback from the air pressure sensor 21 returns to the normal air pressure value, and the detection and analysis module wirelessly controls the deflection control component 6 to stop working through the remote data transmission module. Therefore, it can automatically judge the working status of the material head 2 when the vertical spiral assembly unloads the material, and when the auger in the material head 2 is in an idling state, it automatically controls the material head 2 to deflect to fully contact with the material, and effectively unload the material, further making up for the situation where the operator cannot make accurate judgments during remote operation, and realizes the purpose of remote automated intelligent control, thereby improving the unloading efficiency.

[0032] In addition, the input signal of the idling processing module is connected to a control knob, which is used to control the operation of the deflection control component 6. When the idling processing module determines that the material is compacted or out of contact with the material taking head 2, the idling processing module sends the judgment result to the detection and analysis module, and the detection and analysis module sends a reminder signal to the reminder module. The reminder module reminds the operator of the handheld remote intelligent controller 5 through light and sound that the material taking head 2 is in an idling state. At this time, the operator can actively control the deflection position of the material taking head 2 through the signal feedback from the reminder module. At this time, the operator can send the deflection direction and deflection angle signal to the detection and analysis module by turning the control knob. At this time, the detection and analysis module wirelessly controls the operation of the deflection control component 6 through the remote data transmission module. The operation of the deflection control component 6 will control the material taking head 2 to deflect to the specified direction and angle, which is convenient for flexible control of the position of the material taking head 2 and improves the unloading efficiency of the material taking head 2.

[0033] In this example, see Figure 2 and Figure 3 The middle part of the feeding head 2 is respectively provided with an upper pressure ring 9 and a lower pressure ring 8. The feeding head 2 is provided with a driving part 1, and the output end of the driving part 1 is provided with a bidirectional screw 10. The bidirectional threads arranged in two directions on the bidirectional screw 10 are respectively threadedly connected with the corresponding upper pressure ring 9 and lower pressure ring 8 to control the upper pressure ring 9 and lower pressure ring 8 to move in the same direction or in the opposite direction. The input end of the remote data transmission module is connected with the driving part 1 signal by wireless transmission. By setting the lower pressure ring 8 and the upper pressure ring 9, when the feeding head 2 rotates to break up the material, the lower pressure ring 8 and the upper pressure ring 9 can increase the breaking range of the feeding head 2 and improve the material processing capacity; and when the idling processing module determines that the material is compacted or non-contacted with the feeding head 2, the control The deflection of the material taking head 2 increases its contact range with the material. During the deflection process, when the idle processing module determines that the pressure value fed back by the air pressure sensor 21 has not returned to the normal pressure value, the idle processing module sends an enhanced dispersion signal to the detection and analysis module. At this time, the detection and analysis module wirelessly controls the operation of the driving component 1 through the remote data transmission module. The driving component 1 controls the bidirectional screw 10 to rotate forward and reverse alternately, thereby controlling the lower pressure ring 8 and the upper pressure ring 9 to move in the vertical direction, reducing the contact dead angle between the rotation of the material taking head 2 and the compacted material. At the same time, a collision will occur when the lower pressure ring 8 and the upper pressure ring 9 contact, which can synchronously drive the material taking head 2 to vibrate, thereby improving the dispersion effect on the material and further improving the dispersion effect on the compacted material.

[0034] like Figure 1 and Figure 2As shown, a rotation control component 7 is installed on the transverse tube 3, and the output end of the rotation control component 7 is connected to the material retrieving head 2 to drive the material retrieving head 2 to rotate around its axis. The rotation control component 7 drives the material retrieving head 2 to rotate, thereby controlling the rotation of the material retrieving head 2, breaking up the material, and at the same time rolling the material into the material retrieving head 2, thereby improving the unloading efficiency of the material. Example 2

[0035] The difference from the first embodiment is that in order to reduce the collision of the material taking head 2 during the remote operation, Figure 5 and Figure 6 As shown, a feeding auger 17 is installed in the feeding head 2, and a collision detection chamber 9 is fixed in the middle of the feeding detection chamber 11. The top central axis of the feeding auger 17 extends to the inner cavity of the collision detection chamber 9. The port of the feeding detection chamber 11 and the outer ring of the feeding auger 17 are sealed by a sealing ring 23. An air pressure sensor 20 is installed in the inner cavity of the feeding detection chamber 11. The input end of the remote data transmission module is connected to the air pressure sensor 20 signal through wireless transmission. When the feeding head 2 is unloading the material, there will be contact with the partition in the cabin, especially when unloading the material at the edge of the cabin. At this time, when the feeding head 2 is subjected to a large external force on the side, the internal feeding auger 17 is offset, and the offset feeding auger 17 squeezes the inner cavity of the collision detection chamber 9, and the air pressure sensor 20 will detect The air pressure value is wirelessly transmitted to the detection and analysis module in real time through the remote data transmission module. The detection and analysis module compares the pressure value fed back by the air pressure sensor 20 with the normal pressure value (the normal pressure value when the feeding auger 17 rotates normally is preset in the detection and analysis module). When the detection and analysis module determines that the pressure value fed back by the air pressure sensor 20 is greater than the normal pressure value, it determines that the feeding auger 17 is in an offset state, and determines that the feeding head 2 is subjected to external force and there is a risk of collision with the side wall of the cabin. At this time, the detection and analysis module will send a reminder signal to the reminder module. The reminder module reminds the operator of the handheld remote intelligent controller 5 through lights and sounds that the feeding head 2 is at risk of collision. At this time, the operator can actively control the deflection position of the feeding head 2 through the signal fed back by the reminder module, thereby reducing the collision risk.

[0036] In addition, the inner cavity of the collision detection chamber 9 can be divided into multiple detection chambers around the outer circle of the feeding auger 17. An air pressure sensor 20 is installed in each detection chamber. The increase in the air pressure value detected by the corresponding air pressure sensor 20 can be used to judge whether the feeding auger 17 is offset to the corresponding position, and the offset direction of the feeding auger 17 can be judged more accurately, which is convenient for accurately judging the force direction of the feeding head 2 during remote operation and accurately adjusting the feeding head 2.

[0037] In this embodiment, if Figure 5As shown, a main auger 4 is installed in the middle of the vertical spiral tube 1, and a transfer wheel 18 is rotatably connected to the middle of the transverse tube 3. The main auger 4 and the feeding auger 17 are linked together through the transfer wheel 18. The transfer wheel 18 is driven to rotate by controlling the rotation of the main auger 4, and the feeding auger 17 is driven to rotate synchronously. The material is transferred to the transverse tube 3 through the rotation of the feeding auger 17, and is transferred to the bottom of the main auger 4 through the transfer wheel 18, and is transported upward to the discharge point through the rotation of the main auger 4, thereby realizing the purpose of automatic unloading. Example 3

[0038] The difference from the second embodiment is that since the length of the vertical spiral tube 1 is usually longer, when the vertical spiral tube 1 is blocked, it is easy for materials to accumulate and damage the vertical spiral tube 1 or the main auger 4, causing damage to the equipment. In order to solve the above problem, please refer to Figure 5-Figure 8 A drain port 14 is provided at one end of the horizontal tube 3 near the vertical spiral tube 1, and a sealing plate 15 is vertically inserted at one end of the horizontal tube 3 near the drain port 14. A telescopic member 16 is installed on the horizontal tube 3, and the output end is connected to the sealing plate 15. When the vertical spiral tube 1 is blocked, the sealing plate 15 can be driven upward by controlling the telescopic member 16 to allow the blocked material to be discharged through the drain port 14, which is convenient for the maintenance of the vertical spiral tube 1 and the main auger 4.

[0039] It is worth mentioning that a discharge detection chamber 12 is installed at the position corresponding to the bottom port of the horizontal tube 3 and the vertical spiral tube 1, and a sealing pressure plate 24 is provided between the bottom of the inner cavity of the vertical spiral tube 1 and the inner cavity of the discharge detection chamber 12. An air pressure sensor 3 25 is installed in the inner cavity of the discharge detection chamber 12 to detect the air pressure value of the cavity formed by the sealing pressure plate 24 and the inner cavity of the discharge detection chamber 12. When the main auger 4 transports the material upward, when the vertical spiral tube 1 is blocked, the blocked material fills the vertical spiral tube 1 and increases the downward pressure on the sealing pressure plate 24, as shown in FIG. Figure 8 At this time, the air pressure sensor 3 25 detects an increase in the air pressure value, thereby being able to quickly detect the blockage of the vertical spiral tube 1.

[0040] In addition, the remote intelligent controller 5 is also provided with a blockage processing module, the detection and analysis module is signal-connected to the blockage processing module, the input end of the remote data transmission module is signal-connected to the telescopic member 16 and the air pressure sensor 3 25 respectively through wireless transmission, and the blockage processing module signal is connected to the blockage discharge button. When the screw unloader is working to unload the material in the cabin, the material enters through the bottom of the material taking head 2 and enters the vertical spiral tube 1 through the horizontal tube 3. The material moves upward steadily through the vertical spiral tube 1. During this process, the air pressure sensor 3 25 transmits the detected air pressure value to the detection and analysis module in real time through the remote data transmission module. The detection and analysis module sends the air pressure value of the air pressure sensor 3 25 to the blockage processing module for processing. The blockage processing module compares the air pressure value fed back by the air pressure sensor 3 25 with the preset normal air pressure value (the normal air pressure value of the chamber where the air pressure sensor 3 25 is located when the vertical spiral tube 1 is normally unloading is preset in the blockage processing module). When the blockage processing module When the block determines that the air pressure value fed back by the air pressure sensor 3 25 is greater than the preset normal air pressure value, it is determined that the vertical spiral tube 1 is in a blocked state, and the blockage processing module sends the judgment result to the detection and analysis module, and the detection and analysis module sends a reminder signal to the reminder module. The reminder module reminds the operator of the handheld remote intelligent controller 5 by means of light and sound that the vertical spiral tube 1 is in a blocked state, so that the operator can timely understand the working status of the vertical spiral tube 1; after the operator sees the reminder signal sent by the remote intelligent controller 5, he presses the blockage discharge button to send an anti-blocking signal to the detection and analysis module, and the detection and analysis module wirelessly controls the telescopic part 16 to work through the remote data transmission module, thereby controlling the discharge port 14 to open, so that the material gradually accumulated at the bottom of the vertical spiral tube 1 is quickly discharged through the discharge port 14, reducing damage to the vertical spiral tube 1 and the main auger 4, thereby realizing automated and intelligent judgment of the blockage of the vertical spiral tube 1, and quickly processing through remote control, thereby improving the protection capability of the equipment.

[0041] In this embodiment, a pressure regulating tube 13 connected to the inner cavity is installed on the material taking detection chamber 11, and a pressure regulating tube 2 26 connected to the inner cavity is installed on the material discharging detection chamber 12. Control valves are installed on the pressure regulating tube 13 and the pressure regulating tube 2 26. Gases of different pressures are filled into the corresponding material taking detection chamber 11 and the material discharging detection chamber 12 through the pressure regulating tube 13 and the pressure regulating tube 2 26, so as to adjust the corresponding initial air pressure values. When unloading different types of materials, the sensitivity of the detection results of the corresponding air pressure sensor 1 21 and the air pressure sensor 3 25 can be improved, and the accuracy of the detection results can be improved.
