Description

Technical Field

[0001] The present invention belongs to the field of vehicles specially suitable for collecting garbage, and in particular relates to a loading control method of a garbage compression vehicle, garbage compression equipment and a garbage compression vehicle. Background Art

[0002] Garbage compression truck is a commonly used sanitation equipment. The working process of existing garbage compression truck is as follows: Figure 1 As shown: first, pour the garbage into the filling hopper 3; then, open the scraper 2; after the scraper 2 is opened to the right position, move the slide plate 1 downward; after the slide plate 1 is moved downward to the right position, close the scraper 2; after the scraper 2 is closed to the right position, move the slide plate 1 upward, so as to use the slide plate 1 and the scraper 2 to move the garbage in the filling hopper 3 to the large box 4.

[0003] However, in the above-mentioned garbage compression vehicle, when dumping garbage into the filling hopper 3, the slide plate 1 and the scraper 2 are in the initial state and do not move, the feeding process and the compression process are not linked, and the working efficiency is low.

[0004] In order to overcome the above problems, a Chinese invention patent with authorization announcement number CN115321059B and authorization announcement date 2024.06.21 discloses a remote control garbage compactor electric control system and control method. The electric control system includes a controller for controlling the movement of the scraper, slide plate and rack and a position collector for collecting the positions of the scraper, slide plate and rack. The feeding mode control process in the above patent is as follows: Figure 2 As shown, first, the controller controls the scraper to open in place; then, the controller controls the hanging bracket to lift the bucket to rise in place, and when the bucket rises in place, the material (i.e., garbage) in the loading bucket (i.e., garbage can) is dumped into the filling bucket; after the bucket rises in place, the controller immediately outputs a slide plate descending signal; after the slide plate descends in place, the controller controls the scraper to close, thereby moving the garbage in the filling bucket to the large box of the garbage compression truck; after the scraper is closed in place, the controller controls the slide plate to rise in place to complete a single compression action, thereby compressing the garbage in the large box. During the loading process, the loading bucket is associated with the scraper and slide plate actions, which can realize continuous loading during multi-cycle compression, so that there is no need to interrupt compression during loading.

[0005] The above patent does not disclose the timing of the lowering of the loading bucket, so the loading bucket may be lowered during the process of the slide plate lowering, the scraper closing, the slide plate rising or the scraper opening (equivalent to the "bucket drop" operation being performed at any time). In the process of the scraper opening, the slide plate lowering and before the scraper is completely closed, the scraper is in an open state (including a partially open state and a fully open state).

[0006] Reference Figure 1As shown, when the large box of the garbage compactor is almost full, if the scraper 2 is in the open state, the garbage in the large box will fall into the filling hopper 3, so that the garbage in the garbage bin cannot be completely dumped. In extreme cases, when there is a lot of garbage falling from the large box into the filling hopper 3, this part of the garbage will even block the opening of the garbage bin or enter the garbage bin from the opening of the garbage bin. At this time, although there is still some remaining space in the large box, the staff will think that it is impossible to put more garbage into the large box, that is, the theoretical volume of the large box is greater than the actual volume of the large box, and the space utilization rate of the large box is low. Summary of the invention

[0007] The purpose of the present invention is to provide a garbage compacting truck loading control method to solve the technical problem that in the process of adopting the existing loading mode control process, the theoretical volume of the large box is greater than the actual volume of the large box and the space utilization rate of the large box is low.

[0008] The present invention also aims to provide a garbage compression device to solve the same technical problem as above.

[0009] The present invention also aims to provide a garbage compression vehicle to solve the same technical problem as above.

[0010] To achieve the above purpose, the technical solution of the garbage compression vehicle loading control method provided by the present invention is: A method for controlling the loading of a garbage compactor. First, the rack is controlled to lift the garbage bin to the highest position, and then the garbage bin is lifted to the highest position and waits for a set time after the garbage bin is lifted to the highest position. t , t >0, waiting time t After that, if there is no garbage in the trash can, directly control the hanging frame to drive the trash can back down; if there is still garbage in the trash can, perform the "timely drop" operation. The specific process of the "timely drop" operation is: control the hanging frame to wait until the slide plate rises, and control the hanging frame to keep the highest position for a set time when the slide plate is in the process of rising, so that all the garbage in the trash can is poured out; when all the garbage in the trash can is poured out and the slide plate is in the process of rising, control the hanging frame to start to drive the trash can back down; or, after waiting for a long time t Then directly execute the "timely bucket drop" operation.

[0011] Furthermore, when there is garbage in the trash can, the "timely drop to the trash can" operation is performed, and the visual sensor is used to determine whether there is still garbage in the trash can, and whether to perform the "timely drop to the trash can" operation is determined based on the data detected by the visual sensor.

[0012] Furthermore, the "timely drop to the trash can" operation is performed only when there is garbage in the trash can, and a set signal representing "there is still garbage in the trash can" is sent to the controller through a transmitter that can be manually triggered. After receiving the set signal, the controller controls the hanger to perform the "timely drop to the trash can" operation.

[0013] Furthermore, the waiting time t After that, if there is still garbage attached to the bottom of the trash can, first control the hanging frame to shake up and down to shake the garbage at the bottom of the trash can to the mouth of the trash can. When there is no garbage attached to the bottom of the trash can and there is still garbage at the mouth of the trash can, perform the "timely drop bucket" operation.

[0014] Furthermore, after the hanging rack is shaken up and down each time, it is judged again whether there is garbage adhered to the bottom of the trash can. If there is still garbage adhered to the bottom of the trash can, the hanging rack is shaken up and down again.

[0015] Furthermore, a bucket leaning sensor for detecting whether the trash can is pushed into place and a bucket clamping sensor for detecting whether the trash can is clamped by the hanger are provided on the hanger; when the bucket leaning sensor detects that the trash can is in place, the hanger clamps the trash can, and when the bucket clamping sensor detects that the trash can is clamped by the hanger, the hanger lifts the trash can.

[0016] Furthermore, there are two hanging racks. When lifting a trash can with a smaller capacity, each hanging rack can independently lift the trash can to the highest position and perform the "timely drop" operation; when lifting a trash can with a larger capacity, the two hanging racks can simultaneously lift the trash can to the highest position and perform the "timely drop" operation.

[0017] The beneficial effects of the garbage compactor loading control method provided by the present invention are as follows: the present invention is a pioneering invention. In the prior art, the garbage can can be lowered at any time, but in the present invention, a part of the time period (specifically, the time period when the slide plate is in the process of rising) is selected to make the garbage can lower; in the prior art, the garbage can is only lifted to the highest position after the scraper is opened in place, but in the present invention, the time when the garbage can is lifted to the highest position is not limited. When loading materials using the garbage compactor loading control method of the present invention, the rack first waits for a certain period of time at the highest position. t When there is less garbage in the big box, there is enough space in the filling hopper, and all the garbage can fall into the filling hopper from the trash can; when there is more garbage in the big box, the garbage in the big box will fall into the filling hopper when the scraper is opened, so in the long time t When the slide plate rises, the slide plate and the scraper move the garbage in the filling bucket to the large box, thereby leaving some space in the filling bucket to avoid the garbage in the filling bucket from blocking the mouth of the trash can, ensuring that the garbage in the trash can can be completely poured out, thereby increasing the actual volume of the large box and improving the space utilization rate of the large box.

[0018] To achieve the above purpose, the technical solution of the garbage compression device provided by the present invention is: A garbage compression device includes a large box for storing garbage, a scraper and a slide plate for cooperating with the large box to compress the garbage, a rack for driving the movement of the garbage can, a controller for controlling the movement of the scraper, the slide plate and the rack, and a position collector for collecting the positions of the scraper, the slide plate and the rack. t After the time has passed, if there is still garbage in the trash can, the controller is also used to control the hanger to perform the "timely drop" operation. The specific process of the "timely drop" operation is: control the hanger to wait until the slide plate rises, and control the hanger to keep the highest position for a set period of time when the slide plate is in the process of rising, so that all the garbage in the trash can is poured out. When all the garbage in the trash can is poured out and the slide plate is in the process of rising, control the hanger to start driving the trash can to fall back; if there is no garbage in the trash can, the controller is used to directly control the hanger to fall back or control the hanger to perform the "timely drop" operation.

[0019] Furthermore, the waiting time t After that, if there is still garbage attached to the bottom of the trash can, the controller is also used to control the hanging rack to shake up and down to shake the garbage at the bottom of the trash can to the mouth of the trash can. When there is no garbage attached to the bottom of the trash can and there is still garbage at the mouth of the trash can, the controller is used to control the hanging rack to perform the "timely bucket drop" operation.

When using the garbage compression device in the present invention, the rack first waits for a long time at the highest position. t When there is less garbage in the big box, there is enough space in the filling hopper, and all the garbage can fall into the filling hopper from the trash can; when there is more garbage in the big box, the garbage in the big box will fall into the filling hopper when the scraper is opened, so in the long time t When the slide plate rises, the slide plate and the scraper move the garbage in the filling bucket to the large box, thereby leaving some space in the filling bucket, thereby avoiding the garbage in the filling bucket from clogging the mouth of the garbage bin, ensuring that the garbage in the garbage bin can be completely poured out, thereby increasing the actual volume of the large box and improving the space utilization rate of the large box.

[0021] To achieve the above purpose, the technical solution of the garbage compression vehicle provided by the present invention is: A garbage compression vehicle comprises a vehicle body and a garbage compression device mounted on the vehicle body, wherein the garbage compression device comprises a large box for storing garbage, a scraper and a slide plate for cooperating with the large box to compress the garbage, a rack for driving the movement of the garbage bin, a controller for controlling the movement of the scraper, the slide plate and the rack, and a position collector for collecting the positions of the scraper, the slide plate and the rack. tAfter the time has passed, if there is still garbage in the trash can, the controller is also used to control the hanger to perform the "timely drop" operation.

[0026] The core inventive concept of the present invention is: by controlling the hanging bracket to fall back when the slide plate is in the process of rising, it is ensured that there is enough space in the filling bucket for all the garbage in the garbage bin to be poured out.

[0027] The present invention is further described in detail below in conjunction with embodiments.

[0028] Specific embodiment 1 of the garbage compression vehicle loading control method provided by the present invention: In reference Figure 5-7 On the basis of Figure 3 As shown, the garbage compression vehicle loading control method in this embodiment includes the following steps: Step S1: Control the rack to lift the trash can to the highest position, and wait for a set time after lifting it to the right position. t , t >0, in the set duration t Determine whether there is still garbage in the trash can. If there is still garbage in the trash can, execute step S2. If there is no garbage in the trash can, execute step S3. Step S2, executing the "timely bucket drop" operation, the specific process of the "timely bucket drop" operation is: controlling the hanger to wait until the slide plate rises, and controlling the hanger to maintain the highest position for a set time when the slide plate is in the process of rising, so that all the garbage in the trash can is poured out, and executing step S3 when all the garbage in the trash can is poured out and the slide plate is in the process of rising; Step S3: Control the rack to drive the trash can to fall back.

[0029] In steps S1-S3, the alarm is controlled to sound an alarm to remind passers-by to pay attention to safety; of course, warning tapes can also be pulled or passers-by can be manually reminded to pay attention to safety.

[0030] Among them, in step S1, the visual sensor can be used to determine whether there is still garbage in the trash can, and the data detected by the visual sensor can be used to determine whether to execute step S2 or step S3, that is, the next action of the rack can be controlled according to the data detected by the visual sensor, saving manpower. Of course, the staff can also use their naked eyes to determine whether there is still garbage in the trash can, and send a set signal representing "there is still garbage in the trash can" to the controller through a transmitter that can be manually triggered. After receiving the set signal, the controller controls the rack to perform the "timely drop" operation; if the garbage is in the trash can within the set time, the controller will control the rack to perform the "timely drop" operation. t If the internal controller does not receive the setting signal, step S3 is directly executed.

[0031] When using the above garbage compactor loading control method to load materials, the rack first waits for a long time at the highest position. t When there is less garbage in the big box, there is enough space in the filling hopper, and all the garbage can fall into the filling hopper from the trash can; when there is more garbage in the big box, the garbage in the big box will fall into the filling hopper when the scraper is opened, so in the long time t In this case, the garbage in the trash can cannot be completely poured out. At this time, the hanging bracket waits until the slide plate is in the process of rising. When the slide plate rises, the slide plate and the scraper move the garbage in the filling bucket to the large box, thereby freeing up some space in the filling bucket, thereby preventing the garbage in the filling bucket from blocking the mouth of the trash can, ensuring that the garbage in the trash can can be completely poured out, thereby increasing the actual volume of the large box and improving the space utilization rate of the large box. Among them, the hanging bracket is controlled to fall back only after the slide plate rises for a set period of time. When the hanging bracket starts to fall back, the space in the filling bucket has become larger, increasing the time for the garbage in the trash can to fall, and ensuring that the garbage in the trash can is completely poured out.

[0032] During the loading process, the garbage may adhere to the bottom of the bin. At this time, the garbage cannot be poured out of the bin under the action of gravity alone. In the prior art, the staff can use a wooden stick to knock on the bottom of the bin to make the bin vibrate, so that the garbage no longer adheres to the wall of the bin.

[0033] In order to reduce the workload of the staff, in step S1, the waiting time t After that, if there is still garbage attached to the bottom of the trash can, the "knock the bucket" operation is first performed. The specific process of the "knock the bucket" operation is: control the hanging frame to shake up and down to shake the garbage at the bottom of the bucket to the bucket mouth; when there is no garbage attached to the bottom of the trash can and there is still garbage at the bucket mouth of the trash can, then perform step S2. Specifically, it can be judged by visual sensors or manually whether there is still garbage attached to the bottom of the bucket. When there is garbage attached to the bottom of the bucket, the controller receives the "knock the bucket" signal, and then the controller controls the hanging frame to shake up and down.

[0034] In order to improve the loading efficiency, as a specific implementation, after each up and down swing of the rack, it is determined whether there is garbage attached to the bottom of the trash can. If there is still garbage attached to the bottom of the trash can, the rack is shaken up and down again, thereby reducing the number of swings of the rack and improving the loading efficiency. However, in other specific implementations, it is also possible to determine whether there is garbage attached to the bottom of the trash can after the rack is shaken twice, three times or more times.

[0035] When manually leaning against the trash can, the staff must carefully observe the relative position of the trash can and the hanging rack to avoid accidents caused by the inability to clamp the trash can when the hanging rack rises.

[0036] Reference Figure 5-7 As shown, in order to reduce the workload of the staff, a bucket sensor 1 for detecting whether the trash can is pushed into place and a bucket clamping sensor 2 for detecting whether the trash can is clamped by the hanger are provided on the hanger; when the bucket sensor 1 detects that the trash can is in place, the hanger clamps the trash can, and when the bucket clamping sensor 2 detects that the trash can is clamped by the hanger, the hanger lifts the trash can. Each sensor can be a travel switch, a proximity switch, or other products, as long as it can detect the position of the trash can.

[0037] Specifically, the bucket sensor 1 is mounted on the hanger through the bucket sensor bracket 3, and the bucket clamping sensor 2 is mounted on the hanger through the bucket clamping sensor bracket 4. Each bracket is provided with an arc groove, each sensor is mounted in the arc groove, and each sensor can be moved along the arc groove before being fixed on the bracket to change the installation position and installation angle of the sensor to adapt to different hangers.

[0038] When in use, the staff first pushes the trash can to the rack, and the bucket sensor 1 first detects whether the trash can is in place; when the trash can is in place, the rack starts to rise; after the rack rises a set distance, when the rack clamps the trash can, the bucket sensor 2 can detect that the edge of the trash can is in a specific position, and then the rack can continue to rise. When the rack does not clamp the trash can, the bucket sensor 2 can detect that the edge of the trash can is not in a specific position, and then the rack falls back, thereby preventing the trash can from detaching from the rack when it is lifted by the rack. After the bucket sensor 1 detects the trash can, the alarm is controlled to sound an alarm to remind passers-by to pay attention to safety.

[0039] In shopping malls or residential areas, trash cans are generally divided into two specifications: 240 L and 660 L. In the prior art, two synchronously moving hangers are required to lift a 660 L trash can, and one of the two synchronously moving hangers is required to lift a 240 L trash can. In actual use, one 240 L trash can can be lifted at a time, or two 240 L trash cans can be lifted at a time.

[0040] When only one 240L trash can is lifted at a time, the loading efficiency is low. When two 240L trash cans are lifted at a time, if the garbage in one of the trash cans is not emptied, the hanger cannot fall back, that is, both trash cans cannot fall back, and the loading efficiency is low.

[0041] In order to improve the loading efficiency, as a specific implementation method, the number of hangers is two. When lifting a trash can with a smaller capacity, each hanger can lift the trash can to the highest position and perform the "timely drop" operation; when lifting a trash can with a larger capacity, the two hangers simultaneously lift the trash can to the highest position and perform the "timely drop" operation. When lifting a trash can with a smaller capacity, each hanger works independently. After the garbage in any trash can is dumped, the hanger corresponding to the trash can can fall back, and the loading efficiency is higher. Of course, the trash can in this specific implementation method can also be replaced by other trash cans containing other garbage.

[0042] like Figure 3 As shown, in the invention, the movement of the hanger is achieved by the movement of the loading cylinder and the unloading cylinder, which is conventional prior art in the art and will not be described in detail here.

[0043] Specific embodiment 2 of the garbage compression vehicle loading control method provided by the present invention: The purpose of this embodiment is to provide a garbage compactor loading control method that always performs a "timely bucket drop" operation.

[0044] In reference Figure 3 On the basis of Figure 4 As shown, the main difference between this embodiment and specific embodiment 1 is that: in specific embodiment 1, when setting the time length t It is judged whether there is still garbage in the trash can. When there is no garbage in the trash can, the hanging frame is directly controlled to drive the trash can to fall back to improve the loading efficiency. In this embodiment, the "timely drop bucket" operation is directly executed.

[0045] Specific embodiments of the garbage compression device provided by the present invention: The garbage compression equipment in this embodiment adopts the garbage compression vehicle feeding control method of the present invention.

[0046] Reference Figure 3-7 As shown, when the garbage compression vehicle loading control method in the specific embodiment 1 of the garbage compression vehicle loading control method of the present invention is adopted: the garbage compression equipment includes a large box for storing garbage, a scraper and a slide plate for cooperating with the large box to compress the garbage, a rack for driving the movement of the garbage can, a controller for controlling the movement of the scraper, the slide plate and the rack, and a position collector for collecting the positions of the scraper, the slide plate and the rack. When the rack rises to the highest position and waits tAfter the time has passed, if there is still garbage in the trash can, the controller is also used to control the hanger to perform the "timely drop" operation. The specific process of the "timely drop" operation is: control the hanger to wait until the slide plate rises, and control the hanger to maintain the highest position for a set period of time when the slide plate is in the process of rising, so that all the garbage in the trash can is poured out, and when all the garbage in the trash can is poured out and the slide plate is in the process of rising, control the hanger to start driving the trash can to fall back; if there is no garbage in the trash can, the controller is used to directly control the hanger to fall back.

[0047] When the garbage compression vehicle loading control method in the specific embodiment 2 of the garbage compression vehicle loading control method of the present invention is adopted: if there is no garbage in the garbage bin, the controller is also used to control the hanging bracket to perform the "timely bin drop" operation.

[0048] When in use, the rack waits for a certain period of time in the highest position. t When there is less garbage in the big box, there is enough space in the filling hopper, and all the garbage can fall into the filling hopper from the trash can; when there is more garbage in the big box, the garbage in the big box will fall into the filling hopper when the scraper is opened, so in the long time t When the slide plate rises, the slide plate and the scraper move the garbage in the filling bucket to the large box, thereby leaving some space in the filling bucket, thereby avoiding the garbage in the filling bucket from clogging the mouth of the garbage bin, ensuring that the garbage in the garbage bin can be completely poured out, thereby increasing the actual volume of the large box and improving the space utilization rate of the large box.

[0049] Matching the loading control method of the garbage compacting vehicle in the present invention, the garbage compacting equipment in this embodiment also correspondingly includes a visual sensor connected to the controller for communication, a transmitter that can be manually triggered to send a set signal to the controller representing "there is still garbage in the garbage can", a bucket clamping sensor, a bucket leaning sensor, two brackets that work independently of each other, and other structures, which will not be repeated here.

[0050] Specific embodiments of the garbage compression vehicle provided by the present invention: A garbage compression vehicle comprises a vehicle body and a garbage compression device mounted on the vehicle body. The specific structure of the garbage compression device is the same as the specific structure of any garbage compression device in the present invention, and will not be described in detail herein.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
