Compression vehicle docking system and method

Abstract

The present invention belongs to the field of garbage transfer and discloses a compression vehicle docking system and method. The system enables a small compression vehicle to move to a preset docking-permitting state during the process of docking the rear ends of a large compression vehicle. In this state, the leak-proof docking mechanism in the system can move to a transitional state connecting the large loader feed port and the small vehicle unloading port to prevent leakage during garbage transfer. Simultaneously, the rear end of the small vehicle, along with the small loader, is lifted by the small vehicle lifting mechanism to a level above the large loader feed port, allowing the small loader to flip upward to open the small vehicle unloading port, thereby enabling the small compression vehicle to unload from the large compression vehicle, effectively improving garbage transfer efficiency and reducing operating costs.

Description

Technical Field

[0001] The present invention relates to the technical field of garbage transfer, and in particular to a compression vehicle docking system and a compression vehicle docking method. Background Art

[0002] In recent years, with the acceleration of urbanization, cities are getting bigger and bigger, and land is becoming more and more scarce. Some cities are gradually canceling garbage stations and switching to direct transportation mode to transport urban garbage to garbage disposal terminals over long distances. Figure 14 The figure shows a docking system for a small garbage truck and a large compactor, as disclosed in CN106742980B. By inserting the rear of the small garbage truck into the loader of the large compactor, garbage can be transferred between the two vehicles. However, since these common small garbage trucks lack a loader at the rear and a compactor function, they can only load a small amount of garbage at a time. Consequently, the amount of garbage that can be transferred to the large compactor at a time is also small, resulting in low garbage transfer efficiency and poor economic efficiency.

[0003] However, if the small garbage truck is replaced by a small compacting truck equipped with a filler and docked with a large compacting truck, there will inevitably be the problem of interference between the fillers of the two vehicles, and it will be impossible to effectively dock the rear ends of the small compacting truck with the large compacting truck to transfer garbage without leakage. This is also the key reason why the existing technology has not yet switched to using a small compacting truck for docking despite knowing that ordinary small garbage trucks have a small loading capacity. Summary of the Invention

[0033] A second aspect of the present invention provides a compression vehicle docking method, comprising:

[0034] During the process of the small compacting vehicle and the large compacting vehicle forming a rear docking, the small compacting vehicle is placed in a preset docking-permitting state so that the small loader can be lifted together with the rear end of the small vehicle compartment;

[0035] In the docking-allowed state, the leak-proof docking mechanism is moved to a transitional connection between the feed port of the large loader and the discharge port of the small carriage;

[0039] Before determining that the height difference is within the allowable docking height difference range and the spacing is within the allowable docking spacing range to determine that the small compression vehicle is in the allowable docking state, the relative positions of the small filler and the large filler feed port are continuously adjusted.

[0040] Optionally, the leak-proof docking mechanism includes a leak-proof plate, one end of which is pivotally connected to the rear end of the large loader feed port. In the process of moving the leak-proof docking mechanism to the transition connection between the large loader feed port and the small compartment unloading port in the docking-allowed state, the other end of the leak-proof plate is flipped upward to dock with the rear end of the small compartment unloading port.

In this state, the leak-proof docking mechanism in the system can move to the transition connection between the large loader feed port and the small compartment discharge port to prevent leakage during the garbage transfer process. At the same time, the rear end of the small compartment has been lifted to a level above the large loader feed port by the small compartment lifting mechanism together with the small loader, so that the small loader can flip upward to open the small compartment discharge port, thereby realizing the unloading of the small compacting vehicle from the large compacting vehicle, effectively improving the garbage transfer efficiency and reducing operating costs.

[0063] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0064] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0065] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used to describe the relative positional relationships of components in the directions shown in the drawings or in the vertical, perpendicular or gravity directions.

[0066] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0067] like Figures 1 to 13 As shown, the first exemplary embodiment of the present invention provides a compression vehicle docking system, which includes a small compression vehicle, a large compression vehicle 1 and a monitoring system.

[0068] Specifically, the small compression truck includes a small compartment 5 for loading garbage and having a small compartment unloading port at the rear, a small loader 4 arranged at the rear end of the small compartment 5 for pressing the garbage collected at the feeding port of the small loader into the small compartment 5, and a small compartment lifting mechanism capable of lifting the rear end of the small compartment 5 together with the small loader 4 in a closed state (that is, when the small compartment unloading port is closed). The opening or closing of the small loader 4 is usually driven by the small loader lifting cylinder 14.

[0069] The large compacting vehicle 1 comprises a large compartment for loading garbage, a large loader arranged at the rear end of the large compartment for compacting garbage collected at the feed port of the large loader into the large compartment, and a leak-proof docking mechanism movably arranged on the large loader.

[0070] The monitoring system can monitor whether the small compacting vehicle is in a preset docking state during the process of docking the small compacting vehicle with the large compacting vehicle 1. In this docking state, the leak-proof docking mechanism can move to a transitional position to connect the large loader inlet and the small compartment discharge port to prevent leakage during the garbage transfer process. At the same time, the rear end of the small compartment 5, together with the small loader 4, is lifted by the small compartment lifting mechanism to a position higher than the large loader inlet, allowing the small loader 4 to flip upward to open the small compartment discharge port, thereby enabling the small compacting vehicle to unload the garbage onto the large compacting vehicle 1.

[0071] It can be seen that the compression vehicle docking system of this exemplary embodiment is specifically aimed at the loader interference problem that cannot be solved in the prior art (for example, when the two rear ends are too close, the large loader blocks the small loader from opening, or when the small loader can be opened, the distance between the two rear ends is too large, resulting in material leakage). The above-mentioned special design and limitation are respectively made to the structure of the small compression vehicle, the structure of the large compression vehicle 1, and the docking state of the two vehicles, so that the small compression vehicle and the large compression vehicle 1 can effectively realize the rear-end docking to transfer garbage without leaking, thereby effectively improving the garbage transfer efficiency and reducing operating costs.

[0072] Reference Figure 1 、 Figure 6 and Figure 7 , the monitoring system may include a first distance sensor 16, a second distance sensor 19 and a processor.

[0073] Among them, the first distance sensor 16 can monitor the first height K3 of the bottom end of the small loader 4 relative to the ground and the first distance K5 between the bottom end of the small loader 4 and the top end of the large loader feed port. For example, the first distance sensor can be set at the bottom end of the small loader 4.

[0074] The second distance sensor 19 can monitor the second height of the top of the large filler feed port relative to the ground. For example, the second distance sensor 19 can be set between the top and bottom ends of the large filler hopper of the large filler, and the large filler feed port is formed at the top of the large filler hopper. At this time, the second distance sensor 19 can measure the second height K2+K4 by measuring its own height K2 relative to the ground and measuring the vertical distance K4 between itself and the top of the large filler hopper.

[0075] The processor communicates with the first distance sensor 16 and the second distance sensor 19, and is configured to determine that the small compression vehicle is in a docking-allowed state and generate a docking-allowed signal when it is determined that the height difference between the first height K3 and the second height K2+K4 is within the preset allowable docking height difference range and the first spacing K5 is within the preset allowable docking spacing range.

[0076] In other words, when the height difference between the first height K3 and the second height K2 + K4 falls within the allowable docking height difference range, it can be determined that the bottom of the small loader 4 is a certain distance above the top of the large loader's feed opening, ensuring that the small loader's 4 upward opening movement will not be interfered with by the bottom of the large loader. Furthermore, when the first spacing K5 falls within the allowable docking spacing range, it can be further determined that the leak-proof docking mechanism can be moved to transition between the large loader's feed opening and the small carriage's discharge opening, and that the small loader's 4 upward opening movement will not be interfered with by the top of the large loader. Therefore, when both conditions are met, it can be determined that both the loader interference and material leakage issues have been resolved, allowing docking.

[0077] The docking permission signal generated by the processor can be a control signal, a reminder signal, or a combination of the two signals. When a control signal is generated, the processor can control the movement of the leak-proof docking mechanism and / or control the small filler 4 to open upward, thereby improving the automation and intelligence of the system. When a reminder signal is generated, the operator can be reminded that the small compression vehicle is currently in a docking permission state. If the control signal is not generated synchronously at this time, the operator can manually control the movement of the leak-proof docking mechanism and / or manually control the small filler 4 to open upward. Therefore, this embodiment does not limit whether the subsequent specific docking action is automatically performed when it is determined that the small compression vehicle is in a docking permission state.

[0078] In one embodiment, the leak-proof docking mechanism may include a leak-proof plate 3 and a flipping drive mechanism, one end of the leak-proof plate 3 is pivotally connected to the rear end of the large loader feed port, and the flipping drive mechanism can drive the other end of the leak-proof plate 3 to flip upward, so that in the docking allowed state, the other end of the leak-proof plate 3 can dock with the rear end of the small compartment unloading port, thereby preventing garbage from falling to the ground when being discharged from the small compartment unloading port.

[0079] To further improve the anti-leakage effect of docking, refer to Figure 1 and Figure 2 A docking plate 15 can be set at the rear end of the small car unloading port. When the flip driving mechanism drives the leakage-proof plate 3 to flip upward to dock with the rear end of the small car unloading port, the leakage-proof plate 3 and the docking plate 15 are roughly docked. For example, the leakage-proof plate 3 and the docking plate 15 are docked at the plate ends, the docking plate 15 overlaps the upper plate surface of the leakage-proof plate 3, and a small distance is left between the upper plate surface of the leakage-proof plate 3 and the lower plate surface of the docking plate 15. These are all roughly docked situations. It is sufficient to ensure that garbage will not leak from the docking point.

[0080] In the case of a leak-proof plate 3, refer to Figure 8 The first distance sensor 16 can monitor a second distance K6 between the bottom end of the small filler 4, which is in a closed state (i.e., the small compartment discharge port is closed) and the upper surface of the upwardly flipped leak-proof plate 3 when docking is permitted. The processor can be configured to, upon determining that the second distance K6 is within a preset allowable discharge distance range, determine that the leak-proof plate 3 has at least flipped upward to a horizontal position and generate a signal to permit discharge.

[0081] By monitoring the second spacing K6, the specific position of the leak-proof plate 3 can be accurately determined. When the leak-proof plate 3 is flipped upward to a horizontal position or more than a horizontal position, it can be determined that the leak-proof plate 3 can now receive the garbage discharged from the small compartment discharge port and prevent the garbage from falling to the ground. Therefore, it is determined that the small filler 4 can be opened at this time. If the small filler 4 is opened at the same time as the leak-proof plate 3 is flipped upward to a horizontal position, the unloading operation can be further accelerated, thereby further improving the efficiency of garbage transfer.

[0082] The processor-generated signal allowing unloading can be a control signal, a reminder signal, or a combination of these. When a control signal is generated, the processor can control the small loader 4 to open upward, enhancing the automation and intelligence of the system. When a reminder signal is generated, the operator is reminded that the small compacting vehicle is currently in a state allowing unloading. If a control signal is not generated simultaneously at this time, the operator can manually control the small loader 4 to open upward. Therefore, this embodiment does not restrict whether the subsequent opening of the small loader is automatically executed after the small compacting vehicle is determined to be in a state allowing unloading.

[0083] In the case where the second spacing K6 can be monitored, if the small filler 4 begins to flip upward and open before the leak-proof plate 3 docks with the rear end of the small compartment discharge port, refer to Figure 9The processor can be further configured to control the leak-proof plate 3 and the small loader 4 to work in conjunction with each other during the upward flipping and opening of the small loader 4, so that the second gap K6 remains within the allowable unloading gap range. This can further improve the reliability of the leak-proof plate 3. Because if the opening speed of the small loader 4 is faster than the upward flipping speed of the leak-proof plate 3, the second gap K6 may suddenly become larger, thereby increasing the risk of garbage leaking from this gap. Therefore, the measures of this embodiment can effectively avoid this unfavorable situation.

[0084] In addition, when the leakage prevention plate 3 is provided, refer to Figure 1 and Figure 9 The monitoring system may include a third distance sensor 18, which is capable of monitoring a third distance K7 between the upper surface of the leak-proof plate 3, which is flipped upward in the docking-permitted state, and the rear end of the small car discharge port. For example, the third distance sensor 18 may be disposed on the leak-proof plate 3. When a docking plate 15 is provided at the rear end of the small car discharge port, the third distance K7 is the distance between the upper surface of the leak-proof plate 3 and the docking plate 15. Furthermore, a processor may communicate with the third distance sensor 18 and, upon determining that the third distance K7 is within a preset target docking distance range, be configured to determine that the leak-proof plate 3 is docked with the rear end of the small car discharge port (i.e., the approximate docking described above) and generate a leak-proof plate stop signal.

[0085] It can be seen that by monitoring the third distance K7, the timing of the docking of the leak-proof plate 3 with the rear end of the small car unloading port can be accurately judged, so that the leak-proof plate 3 can be controlled to stop rotating in time to avoid excessive pressure contact between the leak-proof plate 3 and the rear end of the small car unloading port and cause damage, or prevent the leak-proof plate 3 from excessively flipping over and causing it to separate from the rear end of the small car unloading port again, thereby failing to effectively receive the garbage discharged from the small car unloading port and causing leakage.

[0086] The leak-proof plate stop signal generated by the processor can be a control signal, a reminder signal, or a combination of these two signals. When a control signal is generated, the processor can control the leak-proof plate 3 to stop automatically, thereby improving the automation and intelligence of the system. When a reminder signal is generated, the operator can be reminded that the leak-proof plate 3 and the rear end of the small compartment discharge port have completed docking or basically completed docking. If the control signal is not generated synchronously at this time, the operator can manually control the leak-proof plate 3 to stop. Therefore, this embodiment does not limit whether the subsequent leak-proof plate stop action is automatically executed when it is determined that the third spacing K7 is within the target docking spacing range.

[0087] Before the small compression vehicle is in the docking state, the small compression vehicle can also be set to the pre-docking state. Figure 4The monitoring system may include a fourth distance sensor 17, which can monitor a fourth distance K1 (i.e., tail distance) between the rear ends of the small compacting vehicle and the large compacting vehicle 1 during the process of docking the two vehicles. For example, the fourth distance sensor 17 can be disposed at the rear end of the small loader 4. In addition, the processor can communicate with the fourth distance sensor 17 and be configured to determine that the small car lifting mechanism can start operation and generate a small car lifting signal when it is determined that the fourth distance K1 is within a preset preparatory docking distance range.

[0088] In other words, in the initial stage when the rear end of the small compacting vehicle gradually approaches the rear end of the large compacting vehicle 1, by monitoring the fourth distance K1, the small compacting vehicle can enter the pre-docking state before entering the docking state. In the pre-docking state, the small carriage 5 needs to be raised to prevent the small loader 4 from colliding with the large loader during the process of the small compacting vehicle entering the docking state.

[0089] The small car lifting signal generated by the processor can be a control signal, a reminder signal, or a combination of the two signals. When a control signal is generated, the processor can control the small car lifting mechanism to automatically start action, thereby improving the automation and intelligence of the system. When a reminder signal is generated, the operator can be reminded that the small compression vehicle is currently in a pre-docking state. If the control signal is not generated synchronously at this time, the operator can manually control the small car lifting mechanism to start action. Therefore, this embodiment does not limit whether the subsequent small car lifting action is automatically performed when it is determined that the small compression vehicle is in a pre-docking state.

[0090] Reference Figure 4 and Figure 5 The front bottom of the small car 5 can be pivotally connected to a translation member 9. The subframe 10 of the small compression vehicle can be provided with a translation slot for the translation member 9 to translate in the front-to-back direction. The rear end of the translation slot is provided with a limit baffle 8 for limiting the rearward movement of the translation member 9. The small car lifting mechanism includes a small car lifting cylinder 13 arranged behind the limit baffle 8. The front and rear ends of the small car lifting cylinder 13 are respectively pivotally connected to the subframe 10 and the rear bottom of the small car 5.

[0091] When the small carriage lifting mechanism begins to operate, the small carriage lifting cylinder 13 begins to extend, initially driving the translating member 9 to translate rearward within the translation slot until the translating member 9 is stopped by the stopper 8. As the small carriage lifting cylinder 13 continues to extend, the rear end of the small carriage 5, along with the small loader 4, is lifted. If a pre-docking state is provided, in this state, the small carriage 5 first translates rearward as a whole, closer to the rear of the large compacting vehicle 1. The rear end of the small carriage 5, along with the small loader 4, is then lifted. The length L4 of the translation slot in the fore-aft direction can be adjusted according to actual needs.

[0092] Reference Figure 11 and Figure 13 The monitoring system may include a displacement sensor capable of monitoring the extension displacement of the pusher cylinder 12. For example, the displacement sensor may be built into the pusher cylinder 12. Furthermore, the processor may communicate with the displacement sensor and be configured to control the pusher cylinder 12 to extend backward by a preset displacement L5 during each compression cycle t1 of the large compression vehicle 1 during the process of the small compression vehicle unloading into the large compression vehicle 1, satisfying the following: L5 = n*V1 / S2. Here, n is the compression ratio of the garbage in the small compartment 5 (the compression ratio is the ratio of the volume of the garbage after compression to the volume before compression), V1 is the volume of the large loader hopper equipped with the large loader feed port, and S2 is the cross-sectional area of ​​the small compartment 5. This configuration enables the small and large compression vehicles to be linked during the garbage transfer process, ensuring that garbage discharged from the small compression vehicle can be smoothly compressed and loaded into the large compartment by the large loader, and that the amount of garbage discharged by the small compression vehicle each time is equal to the amount of garbage compressed and loaded into the large compartment by the large loader each time.

[0093] Reference Figure 12 The small compacting vehicle may include a push shovel 7 disposed in the small compartment 5, an auxiliary unloading push plate 6 disposed on the rear side of the push shovel 7, and a swing drive mechanism for driving the top of the auxiliary unloading push plate 6 to swing backward. For example, the swing drive mechanism may include a push plate cylinder 11, the front end of which is connected to the front inner wall of the small compartment 5, and the rear end of which is connected to the auxiliary unloading push plate 6, so that the top of the auxiliary unloading push plate 6 is driven to swing backward by the extension of the push plate cylinder 11. In this way, when some garbage in the small compartment 5 still remains on the rear side of the auxiliary unloading push plate 6 when the push shovel cylinder 12 is fully extended, the top of the auxiliary unloading push plate 6 can be driven to swing backward by the swing drive mechanism to completely discharge the remaining garbage. In particular, when the rear end of the small compartment 5 is lifted, it is more conducive to the complete discharge of the remaining garbage.

[0094] Refer again Figure 1 、 Figure 2 and Figure 4 , enclosures 20 can be provided on the left and right sides of the large loader, and a rear door body 2 can be provided at the rear end of the large loader to open or close the feed opening of the large loader. In this way, when the large compacting vehicle is driving, the rear door body 2 can be used to close the feed opening of the large loader, thereby concealing the ugliness and odor, and preventing garbage from flying and odor from wafting out. In the case where a leak-proof plate 3 is provided, when the rear door body 2 closes the feed opening of the large loader, the leak-proof plate 3 can be flipped upward to fit the rear end surface of the rear door body 2, thereby preventing the rear door body 2 from opening during driving.

[0095] By providing the aforementioned multiple distance sensors and processors, regardless of the model of the large or small compactor 1, the two vehicles can be smoothly docked, thereby enabling waste transfer between vehicles without leaking material. In other words, the compactor docking system of this exemplary embodiment is highly versatile and can effectively handle the docking scenarios of different compactor truck types, providing a reliable means for achieving an efficient direct waste transport model.

[0096] In addition, this exemplary embodiment also makes some optimized designs for the functions of the compression vehicle, and these optimized designs are applicable to different types of compression vehicles, including the large compression vehicle 1 and the small compression vehicle mentioned above.

[0097] Specifically, the optimized compacting vehicle includes a displacement sensor, an electro-proportional relief valve, and a processor. Specifically, the displacement sensor detects changes in the displacement of the dozer blade. The electro-proportional relief valve regulates the return oil pressure of the multi-stage telescopic cylinder connected to the dozer blade during the compacting vehicle's compacting operation. The processor communicates with the displacement sensor and the electro-proportional relief valve, respectively, and is configured to control the electro-proportional relief valve to reduce the return oil pressure accordingly based on changes in the dozer blade's displacement detected by the displacement sensor during compacting operation.

[0098] As the compacting truck continuously presses garbage into the compartment, as the amount of garbage pressed increases, the dozer initially at the rear of the compartment continuously overcomes the return oil pressure of the multi-stage telescopic cylinder and moves forward due to the continuous pressure, until it moves forward to the fully retracted state of the multi-stage telescopic cylinder.

[0099] When the shovel moves forward, the garbage in the front is also subject to a certain forward resistance. At this time, if you want to ensure that the compression density of the garbage in the rear is roughly the same as that of the garbage in the front, you must reduce the return oil pressure of the multi-stage telescopic cylinder. In this way, the reduced return oil pressure and the forward resistance to the garbage in the front are superimposed to form the forward resistance to the garbage in the rear at this time, so that the forward resistance to the garbage in the rear at this time is roughly the same as the forward resistance to the garbage in the front when it was compressed before, thereby ensuring that the compression density of garbage in each area of ​​the car is roughly the same.

[0100] The return oil pressure can be adjusted by the processor to control the electric proportional relief valve according to the displacement change of the dozer blade detected by the displacement sensor.

[0101] Therefore, by adopting the compacting vehicle of this embodiment, the amount of garbage loaded in a single trip during long-distance transportation can be increased, thereby effectively reducing operating costs and improving garbage transfer efficiency.

[0102] In addition, when the bulldozer is near the rear of the carriage during the filling operation, the return oil pressure of the multi-stage telescopic cylinder is still relatively high, which can prevent the bulldozer from moving forward due to the expansion of the garbage. This ensures that the bulldozer moves backward due to the filling of the garbage, rather than due to the pressure exerted by the expansion of the garbage. In this way, the compression density of the garbage can be guaranteed, and the expansion of the garbage can be prevented from occupying the space in the carriage.

[0103] Compacting trucks typically also include a hydraulic transmission system connected to the multi-stage telescopic cylinder pipeline and a power system that provides hydraulic power to the hydraulic transmission system. During the unloading operation of the compacting truck, the multi-stage telescopic cylinder continuously extends backward. The diameter of the rear stage of the multi-stage telescopic cylinder is smaller than that of the front stage. In other words, the cross-sectional area at the rear of the multi-stage telescopic cylinder is smaller than that at the front. Therefore, if the hydraulic power output of the power system remains constant, the more the multi-stage telescopic cylinder extends, the less thrust it exerts on the garbage, which may result in the garbage being unable to be pushed out.

[0104] To this end, in the case of the aforementioned processor, the processor can further be configured to communicate with the power system and, during the unloading operation of the compacting vehicle, can be further configured to control and adjust the hydraulic power output by the power system based on the displacement changes of the dozer blade detected by the displacement sensor, so as to maintain a uniform extension speed of the multi-stage telescopic cylinder. In other words, in this embodiment, the hydraulic power output by the power system is adjustable. The further the multi-stage telescopic cylinder extends rearward, the greater the hydraulic power output by the power system can be adjusted accordingly. This avoids the phenomenon of the multi-stage telescopic cylinder extending more and exerting less thrust, ensuring that the multi-stage telescopic cylinder always has sufficient thrust to discharge the garbage and achieving a uniform unloading speed.

[0105] A second exemplary embodiment of the present invention further provides a compression vehicle docking method, comprising:

[0106] Step S1: During the process of rear-end docking between the small compacting vehicle and the large compacting vehicle 1, the small compacting vehicle with the small filler 4 and the rear end of the small carriage 5 lifted is placed in a preset docking-permitting state;

[0107] Step S2: in the docking-allowed state, the leak-proof docking mechanism is moved to a transitional connection between the feed port of the large loader and the discharge port of the small carriage;

[0108] Step S3: In the docking-allowed state, the small filler 4 that has been lifted to a position higher than the feeding port of the large filler is flipped upward to open the unloading port of the small compartment, so that the small compression vehicle can unload materials into the large compression vehicle 1 .

[0109] As can be seen from the first exemplary embodiment described above, the small loader 4 can begin to flip upward to open the small compartment discharge port before the leak-proof docking mechanism finally transitions to connect the large loader feed port and the small compartment discharge port. Therefore, during step S2, step 3 can be initiated at an appropriate time, rather than having to wait until step S2 is completed before starting step S3.

[0110] In addition, the compression vehicle docking method of this exemplary embodiment can be executed with the aid of the compression vehicle docking system of the first exemplary embodiment, but is not limited to being executed with the aid of this system. For example, full manual control or semi-automatic control can also be adopted, rather than having to be automatically executed with the aid of components such as distance sensors.

[0111] In one embodiment, step S1 includes:

[0112] Determine whether the height difference between the bottom end of the small filler 4 and the top end of the feed opening of the large filler is within a preset allowable docking height difference range, and whether the distance between the bottom end of the small filler 4 and the top end of the feed opening of the large filler is within a preset allowable docking distance range;

[0113] Before determining that the small compression vehicle is in a docking state, the relative positions of the small filler 4 and the large filler feed port are continuously adjusted after determining that the height difference between the bottom end of the small filler 4 and the top end of the large filler feed port is within the allowable docking height difference range and the distance between the bottom end of the small filler 4 and the top end of the large filler feed port is within the allowable docking distance range.

[0114] The above judgment process can be realized with the help of the distance sensor and processor in the compression vehicle docking system of the first exemplary embodiment, but in the case of full manual control or semi-automatic control, it can also be judged by manual visual inspection. However, relatively speaking, the judgment made through the communication and cooperation between the distance sensor and the processor is more accurate and efficient.

[0115] In one embodiment, the leak-proof docking mechanism includes a leak-proof plate 3, one end of which is pivotally connected to the rear end of the large loader feed port. When the docking is allowed, the leak-proof docking mechanism is moved to the transition connection between the large loader feed port and the small compartment discharge port, and the other end of the leak-proof plate 3 is flipped upward to dock with the rear end of the small compartment discharge port.

[0116] It should be noted that the flipping action of the leak-proof plate 3 does not necessarily have to be driven by the flipping drive mechanism in the compression vehicle docking system of the first exemplary embodiment, but can also be performed by manual flipping, or if a flipping drive mechanism is provided, it can be selectively performed by the flipping drive mechanism or manual flipping.

[0117] In one embodiment, when the other end of the leakage prevention plate 3 is at least flipped upward to be in a horizontal state, the small filler 4 is flipped upward to open.

[0118] In one embodiment, when the small filler 4 is flipped upward and opened before the leak-proof plate 3 is docked with the rear end of the small compartment unloading port, the distance between the bottom end of the small filler 4 and the upper plate surface of the upwardly flipped leak-proof plate 3 is maintained within a preset allowable unloading distance range.

[0119] In one embodiment, before the small compression vehicle is placed in a docking-allowed state, the distance between the tails of the small compression vehicle and the large compression vehicle 1 facing each other is first made within a preset pre-docking distance range to start lifting the rear end of the small carriage 5 together with the small filler 4.

[0120] When the compressor docking system or compressor docking method of the present invention is used to dock the small compressor vehicle with the large compressor vehicle 1, the following steps can be performed in sequence: Figures 3 to 12 The steps shown in the figure can also be adaptively adjusted according to actual conditions, and the present invention does not limit this.

[0121] Refer to the following Figures 3 to 12 In the order of, an optional compression vehicle docking method performed by the compression vehicle docking system of the first exemplary embodiment is described as a whole to more intuitively explain the design concept of the present invention.

[0122] First, refer to Figure 3 and Figure 4 Before entering the preparatory docking state, the rear ends of the large compression vehicle 1 and the small compression vehicle are first oriented toward each other, and the leak-proof plate 3 originally attached to the rear door body 2 is flipped downward to be perpendicular to the ground to open the rear door body 2.

[0123] Then the rear end of the small compression vehicle is gradually brought closer to the rear end of the large compression vehicle 1. When the fourth distance sensor 17 detects that the fourth distance K1 between the two rear ends is within the preset pre-docking distance range, the processor determines that the small compression vehicle is in a pre-docking state at this time, thereby controlling the small vehicle lifting mechanism to start action.

[0124] Next, refer to Figure 5 and Figure 6 In the early stages of the car lift mechanism's operation, driven by the car lift cylinder 13, the car 5 and the small loader 4 move horizontally toward the rear of the large compactor. When the translation distance reaches L4, the translation member 9 at the front bottom of the car 5 is stopped by the stopper 8 at the rear end of the translation slot of the subframe 10, preventing further translation. However, the car lift cylinder 13 continues to extend, causing the rear end of the car 5 and the small loader 4 to begin to be lifted.

[0125] While the rear end of the small carriage 5, along with the small loader 4, is being lifted, the first distance sensor 16 monitors in real time the first height K3 of the bottom of the small loader 4 relative to the ground, and the second distance sensor 19 monitors in real time the second height K2 + K4 of the top of the large loader's feed port relative to the ground. When the processor determines that the difference between the first height K3 and the second height K2 + K4 is within the preset allowable docking height difference range, the processor controls the carriage lifting mechanism to stop.

[0126] After the car lift mechanism stops moving, refer to Figure 7 The rear end of the small compacting vehicle is brought closer to the rear end of the large compacting vehicle 1. During this process, the first distance sensor 16 monitors in real time the first distance K5 between the bottom end of the small filler 4 and the top end of the large filler's feed port. When the processor determines that the first distance K5 is within the preset allowable docking distance range, the processor determines that the small compacting vehicle is in a docking-permitted state because the height difference between the first height K3 and the second height K2+K4 is already within the preset allowable docking height difference range.

[0127] In the docking state, refer to Figures 8 to 10 The processor controls the tilting drive mechanism to drive the leak-proof plate 3 to begin tilting upward. During this process, the first distance sensor 16 monitors the second distance K6 between the bottom of the small loader 4 and the upper surface of the tilted leak-proof plate 3 in real time. When the processor determines that the second distance K6 is within the preset allowable unloading distance range, the processor determines that the leak-proof plate 3 is now horizontal and controls the small loader 4 to begin opening.

[0128] During the opening process of the small loader 4, the first distance sensor 16 still monitors the second distance K6 in real time to regulate the relative movement speed of the small loader 4 and the leakage-proof plate 3, ensuring that the second distance K6 remains within the allowable unloading distance range before the leakage-proof plate 3 docks with the rear end of the small compartment unloading port. At the same time, the third distance sensor 18 monitors the third distance K7 between the upper plate surface of the leakage-proof plate 3 and the rear end of the small compartment unloading port in real time.

[0129] When the processor determines that the third distance K7 is within the preset target docking distance range, the processor determines that the leak-proof plate 3 has docked with the rear end of the small carriage unloading port, thereby controlling the leak-proof plate 3 to stop moving, but continues to control the small loader 4 to move until the small loader 4 is fully opened.

[0130] After the small filler 4 is fully opened, refer to Figure 11The small compacting vehicle begins to unload materials to the large compacting vehicle 1. During the unloading process, every time the large compacting vehicle 1 completes a filling cycle time t1, the processor controls the push shovel cylinder 12 to extend backward by a preset displacement L5, and satisfies: L5 = n*V1 / S2, until the push shovel cylinder 12 is fully extended.

[0131] After the push blade cylinder 12 is fully extended, refer to Figure 12 The processor controls the swing drive mechanism, which drives the top of the auxiliary unloading push plate 6 to swing backward to discharge some of the garbage remaining on the rear side of the auxiliary unloading push plate 6. This completes the unloading operation of the small compacting vehicle onto the large compacting vehicle 1. After unloading is completed, the small compacting vehicle returns to its initial state, completing a complete docking and unloading process.

[0132] Afterwards, when the large compartment of the large compacting truck 1 is still not full of garbage, another small compacting truck can continue to dock with it to unload until the large compartment is completely filled with garbage, and the large compacting truck 1 can then transport the garbage directly to the garbage disposal terminal.

[0133] The above describes in detail the optional implementation methods of the embodiments of the present invention in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited to the specific details in the above implementation methods. Within the technical concept of the embodiments of the present invention, various simple modifications can be made to the technical solutions of the embodiments of the present invention, and these simple modifications all fall within the scope of protection of the embodiments of the present invention.

In order to avoid unnecessary repetition, the embodiments of the present invention will no longer separately describe various possible combinations.

[0135] In addition, various implementations of the embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the embodiments of the present invention, they should also be regarded as the contents disclosed in the embodiments of the present invention.
