Description

Technical Field

[0001] This invention belongs to the field of unloading equipment technology, specifically a device and method for docking the automatic unloading bin of a fully intelligent sampling vehicle. Background Technology

[0002] Common mobile unloading hoppers typically require manual removal of the hopper to unload the material into the downstream equipment. After unloading, the hopper is moved back, and this process is repeated. Alternatively, slightly better hoppers may have a manual valve at the bottom, which needs to be manually opened for unloading. The most critical part of this process, unloading, is entirely manual.

[0003] Existing devices often fail to maintain a tight seal between the discharge port and the docking device. This lack of a proper seal can lead to moisture leakage during unloading, and the discharge bin cannot be rotated to a specified angle to allow all material to be poured into the docking device at once, resulting in low automation. Therefore, we propose an automatic discharge bin docking device and method for a fully intelligent sampling vehicle to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic unloading bin docking device and method for a fully intelligent sampling vehicle. The purpose is to provide a device that seals and retains water during unloading, and allows the unloading bin of the device to automatically rotate to a specified angle, pouring all the material into the docking device at once. The entire unloading process requires no manual operation, achieving full automation, reducing labor costs, and improving the degree of automation.

[0005] The objective of this invention can be achieved through the following technical solution: A sampling vehicle mounting base is included, with a discharge bin mounting base fixedly connected to its surface. A hinge is fixedly connected to one side of the top of the discharge bin mounting base, and a discharge bin is hinged to the hinge. A discharge bin side door is provided on one side of the discharge bin. A drive assembly for tilting the discharge bin side door is fixedly connected to the discharge bin. A lifting cylinder is hinged to the discharge bin mounting base, with its movable end hinged to a position of the discharge bin away from the hinge. A tilting door mounting base is fixedly connected to the surface of the sampling vehicle mounting base, and a tilting door is hinged to the tilting door mounting base. Hydraulic cylinders are hinged to both ends of the tilting door. A lifting bucket is provided at the lower end of the tilting door, and a lifting bucket top door is hinged to the top of the lifting bucket. A motor for tilting the lifting bucket top door is fixedly connected to the lifting bucket.

[0006] In a preferred embodiment of the present invention, the top of the unloading hopper is provided with an inlet, the inlet is provided with an electric opening and closing door, the electric opening and closing door is provided with a first sealing element, the side of the unloading hopper is provided with an outlet that cooperates with the side door of the unloading hopper, and a second sealing element is provided between the side door of the unloading hopper and the outlet.

[0007] In a preferred embodiment of the present invention, baffles are fixedly connected to both sides of the lifting bucket top door and the tilting door.

[0008] This invention also discloses a method for docking the automatic unloading bin of a fully intelligent sampling vehicle, comprising the following steps: Step 1: Unloading operation: SS1: The motor drives the top door of the lifting bucket to rotate. When the top door of the lifting bucket rotates to a certain tilt angle, the motor stops operating. SS2: While the lifting cylinder extends, the hydraulic cylinder shortens, causing both the unloading bin and the tilting door to tilt to a specified angle, so that the bottom of the tilting door partially overlaps with the top of the lifting bucket top door. SS3: The drive unit drives the unloading hopper side door to flip open the discharge port. Since the unloading hopper is in an inclined state, the material is poured into the flip door, and then the material enters the lifting hopper through the top door of the lifting hopper. Step Two: Unloading Completed After unloading is completed, the side door of the unloading hopper closes automatically through the drive assembly. The motor drives the top door of the lifting bucket to flip in the opposite direction, and the lifting cylinder shortens to make the unloading hopper and the hydraulic cylinder extend to make the flipping door return to the initial horizontal position. Both the unloading operation and the unloading completion operation are controlled by the control box.

[0009] In a preferred embodiment of the present invention, a weighing unit is provided on the unloading hopper mounting base, and the weighing unit is electrically connected to the control box; after the unloading hopper returns to the initial horizontal position, the weighing unit is used to weigh the residual material in the unloading hopper to obtain the residual weight of the material; the residual weight of the material is compared with the residual weight threshold. When the remaining weight of the material is less than the remaining weight threshold, a "complete unloading" signal is generated. This signal triggers the unloading hopper side door, the top door of the lifting hopper, the unloading hopper, and the tilting door to return to their initial positions. When the remaining weight of the material is greater than the remaining weight threshold, a "not completely unloaded" signal is generated and sent to the display module for display. This "not completely unloaded" signal triggers the unloading operation and causes the lifting cylinder to extend and retract, causing the unloading hopper to vibrate back and forth a certain number of times to shake out the remaining material. The shaken-out remaining material passes through the tilting door and the top door of the lifting hopper and enters the lifting hopper for unloading. This is recorded as one re-weighing. The remaining weight of the material is re-weighed according to the above process until a "complete unloading" signal is received, at which point the re-weighing stops. The number of re-weighings is counted and compared with the preset number of weighings. If the number of re-weighings is greater than the preset number of weighings, the unloading operation is completed, and a corresponding residue cleaning signal is generated and sent to the residue processing module.

[0010] In a preferred embodiment of the present invention, the control box further includes a waste disposal module; The residue handling module is used to receive residue cleaning signals and perform personnel allocation operations to obtain corresponding staff; send the unloading hopper information corresponding to the residue cleaning signal to the smart terminal of the corresponding staff member; after receiving the unloading hopper information corresponding to the residue cleaning signal through the smart terminal, the staff member goes to clean the residual material in the unloading hopper.

[0011] In a preferred embodiment of the present invention, the control box further includes: The unloading discrimination module is used for data analysis of information from the lifting bucket top door and the tilting door, specifically: The unloading discrimination module is used for data analysis of information from the lifting bucket top door and the tilting door, specifically: Obtain the horizontal and vertical distances between the top of the flip-top door and the bottom of the lifting bucket door, the angle between the flip-top door and the vertical direction, and the length of the flip-top door. Perform comprehensive calculations on the horizontal and vertical distances, the angle between the flip-top door and the vertical direction, and the length of the flip-top door to obtain the face value. Obtain the relative positions of the lifting bucket and the tilting door from a top-down view, and calculate the actual deviation by measuring their overlap range in the horizontal parallel direction. The deviation value of the unloading bin is obtained by normalizing the actual deviation and the face value. A corresponding threshold is set for the deviation value, and the deviation value is compared with the corresponding threshold. When the deviation value is within the corresponding threshold, an unloading signal is generated. When the deviation value is outside the corresponding threshold, a dispatch signal is generated for the unloading bin and sent to the discrimination processing module. The unloading signal is used to trigger the unloading operation of the current unloading bin, and the dispatch signal is used to trigger the unloading operation of the current unloading bin and sent to the discrimination processing module for corresponding processing. Obtain the horizontal and vertical distances between the top of the flip-top door and the bottom of the lifting bucket top door, the angle between the flip-top door and the vertical direction, and the length of the flip-top door. Using the cosine theorem based on the angle and the door length, calculate the horizontal distance between the bottom and top of the flip-top door, and then use the tangent theorem to calculate the vertical distance between them. Calculate the face value. Calculate the horizontal and vertical distances between the bottom and top of the flip-top door, and use the tangent theorem to obtain the angle between the lifting bucket top door and the horizontal direction. Mark the range of this angle with the horizontal direction as the specified tilt angle range of the lifting bucket top door. The distance between the bottom of the flip-top door and the bottom of the lifting bucket top door is limited to the length of the lifting bucket top door. Obtain the relative positions of the lifting bucket and the tilting door from a top-down view, and calculate the actual deviation by measuring their overlap range in the horizontal parallel direction. The deviation value of the unloading bin is obtained by normalizing the actual deviation and the face value. A corresponding threshold is set for the deviation value, and the deviation value is compared with the corresponding threshold. When the deviation value is within the corresponding threshold, an unloading signal is generated. When the deviation value is outside the corresponding threshold, a dispatch signal is generated for the unloading bin. The unloading signal is used to trigger the unloading operation, and the dispatch signal is used to trigger that the current unloading bin cannot be unloaded, and is sent to the discrimination and processing module for corresponding processing.

[0012] The discrimination and processing module is used to receive the corresponding allocation signal and perform allocation processing operations to obtain the corresponding technical personnel. The corresponding allocation signal and the corresponding unloading bin information are sent to the technical personnel's smart terminal. After receiving the allocation signal and the corresponding unloading bin information through the smart terminal, the technical personnel adjust the position of the unloading bin by operating the sampling vehicle.

[0013] In a preferred embodiment of the present invention, the control box is provided with a display module, which is used to display in real time the top relative position between the tilting door and the lifting bucket, and the side relative position between the tilting door and the top door of the lifting bucket; to display the remaining weight of the material, the number of re-weighing times, the face value and the actual deviation, as well as the corresponding set threshold; to receive the corresponding signal and provide corresponding prompts, and send them to the corresponding module.

[0014] In a preferred embodiment of the present invention, the sampling vehicle mounting base is further provided with an identification unit, which is used to collect and identify information such as the horizontal and vertical distances between the top of the flip door and the bottom of the top door of the lifting bucket, the angle between the flip door and the vertical direction, the length of the flip door, and the relative positions of the lifting bucket and the flip door when viewed from above, so as to obtain the corresponding values.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention enables the unloading hopper to be automatically flipped to a specified angle using the device. The material is then poured into the lifting hopper in one go using the flipping door and the top door of the lifting hopper. The unloading process does not require manual operation, achieving full automation, reducing labor costs, and improving the degree of automation.

[0016] 2. The present invention can form a discharge channel through the flip door and the top door of the lifting bucket, so that the material in the discharge bin can enter the lifting bucket through the discharge channel, ensuring a good tight contact state, so that the material and water are not easy to overflow during the discharge process, thereby ensuring the stability of discharge and improving the accuracy of collection.

[0017] 3. This invention is equipped with a weighing unit and a residue handling module. After unloading is completed, the unloading bin returns to its initial position. The weighing unit weighs the remaining material in the unloading bin to obtain the remaining weight of the material. When the material weight is greater than the remaining weight threshold, the unloading bin is shaken repeatedly to shake out the remaining material, ensuring complete unloading and avoiding affecting the accuracy of the unloading bin's next weighing of material.

[0018] 4. This invention incorporates a discharge judgment module and a judgment processing module. The discharge judgment module analyzes the information from the top door and the tilting door of the lifting hopper to obtain a deviation value. Based on the deviation value, it determines whether the position of the lifting hopper meets the discharge conditions of the unloading bin. If not, it generates a dispatch signal, which is received by the judgment processing module and sent to the intelligent terminal of the processing personnel. After receiving the dispatch signal and corresponding information through the intelligent terminal, the processing personnel perform the corresponding processing through the corresponding operation. This avoids material leakage caused by the lifting hopper position not meeting the discharge conditions, ensuring the accuracy of material discharge from the unloading bin.

[0024] Please see Figures 1-3 As shown, the automatic unloading bin docking device of the fully intelligent sampling vehicle includes a sampling vehicle mounting base 1. An unloading bin mounting base 2 is fixedly connected to the surface of the sampling vehicle mounting base 1. A hinge is fixedly connected to one side of the top of the unloading bin mounting base 2. An unloading bin 3 is hinged to the hinge. An unloading bin side door 5 is provided on one side of the unloading bin 3. A drive assembly for tilting the unloading bin side door 5 is fixedly connected to the unloading bin 3. A lifting cylinder 4 is hinged to the unloading bin mounting base 2. The movable end of the lifting cylinder 4 is hinged to the unloading bin 3 at a position away from the hinge. A tilting door mounting base 6 is fixedly connected to the surface of the sampling vehicle mounting base 1. A tilting door 7 is hinged to the tilting door mounting base 6. Hydraulic cylinders 8 are hinged to both ends of the tilting door 7. A lifting bucket 9 is provided at the lower end of the tilting door 7. A lifting bucket top door 10 is hinged to the top of the lifting bucket 9. A motor 11 for tilting the lifting bucket top door 10 is fixedly connected to the lifting bucket 9.

[0025] Among them, the sampling vehicle mounting base plate 1 is also equipped with a mounting frame (not shown in the attached drawings), and one end of the hydraulic cylinder 8 is fixedly connected to the mounting frame; the bottom of the inner wall of the unloading bin 3 adopts an arc design, which can effectively reduce the probability of materials sticking to the inner wall of the unloading bin 3 during the unloading process.

[0026] The top of the unloading hopper 3 is provided with an inlet, and an electric opening and closing door is provided on the inlet. The electric opening and closing door is provided with a first sealing element. The side of the unloading hopper is provided with an outlet that cooperates with the side door 5 of the unloading hopper. A second sealing element is provided between the side door 5 of the unloading hopper and the outlet.

[0027] By incorporating a first seal and a second seal, moisture overflow from the unloading hopper can be prevented when the electric opening and closing door and the unloading hopper side door 5 are closed, thus ensuring the accuracy of sampling.

[0028] Both sides of the lifting top door 10 and the flip door 7 are fixedly connected with baffles.

[0029] By installing baffles, the material and water can be guided during unloading to prevent spillage.

[0030] This invention also discloses a method for docking the automatic unloading bin of a fully intelligent sampling vehicle, comprising the following steps: Step 1: Unloading operation: SS1: Motor 11 drives the top door 10 of the lifting bucket to rotate. When the top door 10 of the lifting bucket rotates to a certain tilt angle, motor 11 stops operating. SS2: While the lifting cylinder 4 extends, the hydraulic cylinder 8 shortens, causing the unloading bin 3 and the tilting door 7 to tilt to a specified angle, so that the bottom of the tilting door 7 partially overlaps with the top of the lifting bucket top door 10. SS3: The drive assembly drives the unloading bin side door 5 to flip and open the discharge port. Since the unloading bin 3 is in an inclined state, the material is poured into the flip door 7, and the material then enters the lifting bucket 9 through the lifting bucket top door 10. Step Two: Unloading Completed After unloading is completed, the side door 5 of the unloading bin is automatically closed by the drive assembly, the motor 11 drives the top door 10 of the lifting bucket to flip in the opposite direction, the lifting cylinder 4 shortens to make the unloading bin 3 and the hydraulic cylinder 8 extend to make the flipping door 7 return to the initial horizontal position. Both the unloading operation and the unloading completion operation are controlled by the control box.

[0031] A weighing unit is installed on the unloading hopper mounting base 2, and the weighing unit is electrically connected to the control box. After the unloading hopper 3 returns to the initial horizontal position, the weighing unit is used to weigh the remaining material in the unloading hopper 3 to obtain the remaining weight of the material. The remaining weight of the material is then compared with the remaining weight threshold. When the remaining weight of the material is less than the remaining weight threshold, a "complete unloading" signal is generated. This signal triggers the unloading bin side door 5, the lifting bucket top door 10, the unloading bin 3, and the tilting door 7 to return to their initial positions. When the remaining weight of the material is greater than the remaining weight threshold, a "not completely unloaded" signal is generated and sent to the display module for display. This signal triggers the unloading operation and causes the lifting cylinder 4 to extend and retract, causing the unloading bin 3 to vibrate back and forth a certain number of times to shake out the remaining material. The shaken-out remaining material passes through the tilting door 7 and the lifting bucket top door 10 into the lifting bucket 9, where the unloading operation is completed. This is recorded as one re-weighing. The remaining weight of the material is re-weighed according to the above process until a "complete unloading" signal is received, at which point the re-weighing stops. The number of re-weighings is counted and compared with the preset number of weighings. If the number of re-weighings is greater than the preset number of weighings, the unloading operation is completed, and a corresponding residue cleaning signal is generated and sent to the residue processing module.

[0032] The control box also includes a waste disposal module; The residue handling module is used to receive residue cleaning commands and perform personnel allocation and handling operations. Specifically, it obtains the personnel corresponding to the unloading bin of the residue cleaning command; sends information acquisition instructions to the smart terminals of all personnel to obtain the current location and idle / busy status of the cleaning personnel; obtains the personnel in the idle status, calculates the distance between the current location of the idle personnel and the location corresponding to the unloading bin of the residue cleaning command to obtain the bin distance and marks it as GF1. Obtain the total number of cleanings performed by each employee in the current month and their age, and label them as GF2 and GF3 respectively. The warehouse spacing, total number of cleanings in the current month, and working age are normalized, and the values ​​of these three are substituted into the preset formula. The cleaning value B of the staff is obtained; where α and β are preset weight coefficients, which are set by those skilled in the art according to the actual situation; the staff with the largest cleaning value is marked as the cleaning staff; the smaller the distance between the bins, the closer the age is to 20 years old, and the fewer the total number of cleanings in the month, the larger the cleaning value, indicating that the staff is more likely to clean the residual materials in the unloading bin 3; The number and location of the unloading hopper 3 corresponding to the residue cleaning signal are sent to the cleaning personnel's smart terminal. After receiving the unloading hopper number and location corresponding to the residue cleaning signal through the smart terminal, the cleaning personnel go to clean the residual material in the unloading hopper 3.

[0033] The control box also includes: The unloading discrimination module is used to perform data analysis on the information of the lifting bucket top door 10 and the tilting door 7, specifically: Obtain the horizontal distance D and vertical distance H between the top of the flip door 7 and the bottom of the lifting bucket top door 10, the angle q between the flip door and the vertical direction, and the length C of the flip door 7. Using the cosine theorem d = C × sin(q) based on the angle q and the length C, obtain the horizontal distance d between the bottom and top of the flip door 7. Substitute this into the tangent theorem h = Hd / tan(q) to obtain the vertical distance h between the bottom and top of the flip door 7. Substitute this into the preset formula... The face value M is obtained; the horizontal distance d and vertical distance h between the bottom and top of the flip door 7 are calculated, and the angle p between the lifting bucket top door and the horizontal direction is obtained by using the tangent theorem tan p=h / Dd. The range of angles between this angle p and the horizontal direction is marked as the specified tilt angle range of the lifting bucket top door; wherein, the distance between the bottom of the flip door 7 and the bottom of the lifting bucket top door 10 is limited to the length range of the lifting bucket top door 10. Obtain the relative positions of the lifting bucket 9 and the flip door 7 from a top view, and calculate the difference between their values ​​in the horizontal parallel direction, S=S1-S2, to obtain the actual deviation S. The actual deviation S and the surface value M are normalized and their values ​​are taken; then the formula is used. Obtain the deviation value MS of unloading bin 3; where N1 and N2 are preset weight coefficients, which are set by those skilled in the art according to the actual situation; when the deviation value is within the corresponding threshold, an unloading signal is generated; when the deviation value is outside the corresponding threshold, a dispatch signal corresponding to unloading bin 3 is generated; the unloading signal is used to trigger the current unloading bin (3) to perform unloading operation, and the dispatch signal is used to trigger the current unloading bin (3) to not perform unloading operation, and is sent to the discrimination processing module for corresponding processing; the actual deviation can be obtained by formula, the larger the face value, the larger the corresponding deviation value, which means that the probability of material leakage when unloading bin is unloading is greater; by analyzing the information of the lifting bucket top door 10 and the flip door 7, it is determined whether the position of the lifting bucket 9 meets the unloading conditions of unloading bin 3; avoid the situation where the material leakage occurs due to the position of the lifting bucket 9 not meeting the unloading conditions, and ensure the accuracy of material unloading in unloading bin 3.

[0034] The discrimination and processing module is used to receive the corresponding allocation signaling and perform allocation processing operations, specifically: The system retrieves the technical personnel corresponding to the unloading hopper from the allocation command; it sends the command information back to the smart terminals of all technical personnel to obtain the current location and idle / busy status of the technical personnel; it retrieves the technical personnel in the idle status, calculates the distance between the current location of the idle technical personnel and the location corresponding to the unloading hopper of the allocation command to obtain the repair distance and marks it as XJ1; Obtain the total number of processing times, the average processing time, and the corresponding processing duration for each technician in the current month, and label them as XJ2, XJ3, and XJ4, respectively. The average values ​​of trimming distance, total number of processing times in the current month, total number of processing times, and corresponding processing time are normalized, and then the values ​​of these four factors are substituted into a preset formula. The allocation value U of the technician is obtained; where i1, i2, i3 and i4 are preset weight coefficients, which are set by the technicians according to the actual situation; the technician with the largest allocation value is marked as the processing personnel; the smaller the repair distance of the technician, the fewer the total number of processing times in the month, the more the total number of processing times, the shorter the average processing time, and the larger the allocation value, the greater the probability that the technician is selected as the processing personnel and the greater the probability that he / she will adjust the relative position between the unloading hopper 3 and the lifting bucket 9. The corresponding allocation signal and the corresponding unloading bin 3 number and location are sent to the processing personnel's smart terminal; after receiving the allocation signal and the corresponding unloading bin 3 number and location through the smart terminal, the processing personnel adjust the position of the unloading bin 3 by operating the sampling vehicle.

[0035] The control box is equipped with a display module, which is used to display the top relative position between the tilting door 7 and the lifting bucket 9, and the side relative position between the tilting door 7 and the top door 10 of the lifting bucket in real time; to display the material residual weight, number of weighings, surface value and actual deviation, as well as the corresponding set threshold; to receive the corresponding signal and provide corresponding prompts, and send them to the corresponding module.

[0036] The display module displays the received information in text and images, as well as the corresponding signals, providing a clear visual indication of the unloading status.

[0037] The sampling vehicle mounting base 1 is also equipped with an identification unit, which is used to collect and identify information such as the horizontal and vertical distance between the top of the flip door 7 and the bottom of the lifting bucket top door 10, the angle between the flip door and the vertical direction, the length of the flip door, and the relative position of the lifting bucket 9 and the flip door 7 when viewed from above, so as to obtain the corresponding values.

[0038] In specific implementation of this invention: In operation, when unloading is required in the unloading bin 3, the motor 11 drives the top door 10 of the lifting bucket to rotate. When the top door 10 rotates to a certain tilt angle, the motor 11 stops operating, the lifting cylinder 4 is activated to extend, and the hydraulic cylinder 8 is shortened, so that both the unloading bin 3 and the rotating door 7 rotate to the specified tilt angle, so that the bottom of the rotating door 7 partially overlaps with the top of the top door 10, and the top of the rotating door 7 is located at the lower opening of the unloading bin side door 5. The unloading bin side door 5 is automatically opened by the drive assembly, and the material slides down the inner wall of the unloading bin 3 under the action of gravity, passing through the rotating door 7 and the top door 10 into the lifting bucket 9. After unloading is completed, the unloading bin side door 5 is automatically closed by the drive assembly. The machine 11 drives the top door 10 of the lifting bucket to flip in the opposite direction, and the lifting cylinder 4 shortens to make the unloading bin 3 and the hydraulic cylinder 8 extend so that the flip door 7 returns to the initial horizontal position. Through this device, the unloading bin 3 can be automatically flipped to a specified angle. The material is poured into the lifting bucket 9 at one time using the flip door 7 and the top door 10 of the lifting bucket. The unloading process does not require manual operation, realizing full automation, reducing labor costs, and improving the degree of automation. The flip door 7 and the top door 10 of the lifting bucket can form a unloading channel, allowing the material in the unloading bin 3 to enter the lifting bucket 9 through the unloading channel, ensuring a good tight contact state, so that the material and water are not easy to overflow during the unloading process, thereby ensuring the stability of unloading and improving the accuracy of collection.

Perform a comprehensive calculation on the horizontal and vertical distances, the angle between the flip door (7) and the vertical direction, and the length of the flip door (7) to obtain the face value M. ;d is the horizontal distance between the bottom and top of the flip door (7);h is the vertical distance between the bottom and top of the flip door (7); Obtain the relative positions of the lifting bucket (9) and the flip door (7) from a top view, and calculate the actual deviation by calculating the overlap range of them in the horizontal parallel direction; The deviation value of the unloading bin (3) is obtained by normalizing the actual deviation and the surface value; the corresponding threshold value of the deviation value is set and the deviation value is compared with the corresponding threshold value; when the deviation value is within the corresponding threshold value, an unloading signal is generated; when the deviation value is outside the corresponding threshold value, a dispatch signal corresponding to the unloading bin (3) is generated; the unloading signal is used to trigger the current unloading bin (3) to perform unloading operation, and the dispatch signal is used to trigger the current unloading bin (3) to not perform unloading operation and is sent to the discrimination processing module for corresponding processing; The discrimination and processing module is used to receive the corresponding allocation signal and perform allocation processing operations to obtain the corresponding technicians. The corresponding allocation signal and the corresponding unloading bin information are sent to the technicians' smart terminals. After receiving the allocation signal and the corresponding unloading bin (3) information through the smart terminal, the technicians adjust the position of the unloading bin (3) by operating the sampling vehicle.

4. The method for automatic unloading bin docking of the fully intelligent sampling vehicle according to claim 1, characterized in that, A weighing unit is provided on the unloading hopper mounting base (2), and the weighing unit is electrically connected to the control box; after the unloading hopper (3) returns to the initial horizontal position, the weighing unit is used to weigh the residual material in the unloading hopper (3) to obtain the residual weight of the material; the residual weight of the material is compared with the residual weight threshold. When the remaining weight of the material is less than the remaining weight threshold, a discharge completion signal is generated. The discharge completion signal is used to trigger the unloading bin side door (5), the lifting bucket top door (10), the unloading bin (3), and the tilting door (7) to return to their initial positions. When the remaining weight of the material is greater than the remaining weight threshold, an incomplete discharge signal is generated and sent to the display module for display. The incomplete discharge signal is used to trigger the unloading operation and cause the lifting cylinder (4) to extend and retract, driving the unloading bin (3) to shake back and forth a certain number of times to shake out the residual material. The shaken residual material passes through the tilting door (7) and the lifting bucket top door (10) and enters the lifting bucket (9) for unloading completion. This is recorded as one re-weighing. The remaining weight of the material is re-weighed according to the above process until the discharge completion signal is received and the re-weighing stops. The number of re-weighings is counted and compared with the preset number of weighings. If the number of re-weighings is greater than the preset number of weighings, the unloading completion operation is performed, and a corresponding residue cleaning signal is generated and sent to the residue processing module.
