Description

Technical Field

[0001] The utility model relates to the technical field of trash cans, in particular to a bag-breaking and barrel-changing device. Background Technique

[0002] With the acceleration of the urbanization process, garbage disposal has become an important environmental problem. Traditional garbage disposal methods often require manual intervention, which is time-consuming, laborious and inefficient. For example, when putting kitchen waste, it is necessary to separately pour the garbage bag and the internal garbage, which is inconvenient to operate and easy to dirty hands. At the same time, the trash can is prone to overflow when putting garbage, and it is difficult to clean, causing environmental pollution. Therefore, a bag-breaking and barrel-changing device is proposed, which integrates the functions of bag-breaking, separation and barrel-changing, reduces manual operation, and improves the speed and accuracy of garbage disposal.

[0003] Chinese Utility Model Patent Publication No.: CN 211077167 U, discloses: a garbage disposal bin. This garbage disposal bin is designed with two types of bins for dry garbage and wet garbage, enabling users to effectively classify garbage when putting it. In addition, by setting a weighing structure, the trash can can be weighed. The weighing sensor has an information transmission function and real-time feedbacks the weight information to the controller of the control box. In this way, when the garbage is collected to the set weight, the controller of the control box can control the garbage inlet to close, so that users cannot put more garbage, and timely remind users to timely dispose of the garbage in the trash can, preventing the garbage from overflowing. However, this garbage disposal bin has a small volume and cannot hold a large amount of garbage. When putting kitchen waste, users still need to pour the garbage from the garbage bag into the trash can, which is relatively inconvenient to use. Summary of the Invention

[0046] Embodiment 2: As Figures 2-10 shown, as an improvement over the previous embodiment.

[0047] Specifically, the sleeve 705 and the sliding rod 706 are slidably connected, the sliding table cylinder 711 has an inclined structure, and the separating block 710 and the needle 713 are slidably connected. The advantage is that the bag-grabbing and sorting component 7 is provided. When in use, the rodless cylinder three 701 drives the rodless cylinder four 702 to move leftward until it corresponds to the bag-breaking component 6. The rodless cylinder four 702 is started to drive the extension plate 703 to move downward. The separating block 710 contacts the kitchen waste bag until the extension plate 703 reaches the lowermost end of the stroke of the rodless cylinder four 702. The sliding rod 706 slides upward in the sleeve 705, and the spring 708 is compressed. The spring 708 applies a downward pressure to the separating block 710 to press the kitchen waste bag tightly on the bag-breaking hook 605. The sliding table cylinder 711 is started to drive the moving table 712 to move towards the center, and the needle 713 moves through the separating block 710 and then inserts into the upper end of the kitchen waste bag. The two groups of needles 713 fix the kitchen waste bag. After the kitchen waste falls onto the transfer tray 806, the rodless cylinder four 702 drives the needle 713 to move upward, and the rodless cylinder three 701 drives the needle 713 to move rightward until it corresponds to an appropriate trash can 4. The sliding table cylinder 711 is started to drive the needle 713 to move outward. After the needle 713 sinks into the separating block 710, it separates from the garbage bag, and the garbage bag falls into the trash can 4. There is no need for manual pouring of the kitchen waste from the garbage bag, achieving the purpose of separating and storing the garbage and the garbage bag, improving the user experience of throwing garbage, and being relatively practical.

[0048] Specifically, there are three identical barrel-changing assemblies 8. The vertical cross-section of the transfer tray 806 is in an "L" shape. The rotating wheel 807 is slidably connected to the slide rail 805, and the connecting seat 808 is rotatably connected to the rotating seat 810.

In the initial state, the transfer tray 806 is located above the frontmost trash can 4, corresponding to the first discharge opening 502 and the second discharge opening 503, and is used to store garbage and distribute the garbage according to the capacity of the trash can 4. When dumping the garbage, the rodless cylinder five 801 is activated to drive the support 803 to move until the transfer tray 806 reaches above the appropriate trash can 4. Then, the rodless cylinder six 809 is activated to drive the rotating seat 810 to rise. The connecting seat 808 rotates relative to the rotating seat 810, the rotating wheel 807 moves along the slide rail 805, the transfer tray 806 tilts, and the garbage falls into the trash can 4 along the transfer tray 806, completing the barrel change of the garbage.

[0049] Specifically, there are nine identical ultrasonic detectors 9. The ultrasonic detectors 9 correspond to the trash cans 4. The advantage is that the ultrasonic detectors 9 are provided. Corresponding to the trash cans 4, the ultrasonic detectors 9 regularly emit ultrasonic waves to detect the garbage input volume in the trash cans 4, and transmit the data to the external processing center. After analyzing the data, the processing center controls the barrel-changing assembly 8 to distribute and put the garbage into the appropriate trash cans 4, avoiding the situation where the garbage in some trash cans 4 accumulates too little while the garbage in some other trash cans 4 accumulates too much and overflows. When the garbage volume in the trash can 4 is too large, it can feedback to the external processing center to remind the staff to change the barrel, which is very practical.

[0050] Working principle: When in use, in the initial state, the two inclined hoppers 603 are joined and in contact. The rodless cylinder three 701 drives the rodless cylinder four 702 to move leftward until it corresponds to the bag-breaking assembly 6. The transfer tray 806 of the bucket-changing assembly 8 is located below the bag-breaking assembly 6. The user controls the opening of the first discharge port 502 or the second discharge port 503 through the controller at the front end of the discharge plate 501 according to the type of garbage to be put in. If food waste needs to be put in, the user controls the opening of the discharge door 505 of the first discharge port 502. The rodless cylinder one 504 drives the discharge door 505 to move downward. The user puts the food waste into the first discharge port 502. The food waste falls on the inclined hopper 603 along with the bag. The rodless cylinder four 702 is started to drive the extension plate 703 to move downward. The separation block 710 contacts the food waste garbage bag until the extension plate 703 reaches the lowest end of the stroke of the rodless cylinder four 702. The slide rod 706 slides upward in the sleeve 705, and the spring 708 is compressed. The spring 708 exerts a downward pressure on the separation block 710 to press the food waste garbage bag tightly on the bag-breaking hook 605. The bag-breaking hook 605 pierces through the lower end of the garbage bag. The slide table cylinder 711 is started to drive the moving table 712 to move towards the center. The needle 713 moves through the separation block 710 and then inserts into the upper end of the food waste garbage bag. The two groups of needles 713 fix the food waste garbage bag. The rodless cylinder two 602 is started to drive the inclined hopper 603 to move outward. The bag-breaking hook 605 tears the lower end of the garbage bag. The food waste falls onto the transfer tray 806. The rodless cylinder four 702 drives the needle 713 to move upward. The rodless cylinder three 701 drives the needle 713 to move rightward until it corresponds to the appropriate trash can 4. The slide table cylinder 711 is started to drive the needle 713 to move outward. After the needle 713 sinks into the separation block 710, it separates from the garbage bag. The garbage bag falls into the trash can 4. The ultrasonic detector 9 emits ultrasonic waves regularly to detect the amount of garbage put in the trash can 4 and transmits the data to the external processing center. After analyzing the data, the processing center controls the bucket-changing assembly 8 to distribute and put the garbage into the appropriate trash can 4. When dumping the garbage, the rodless cylinder five 801 is started to drive the bracket 803 to move until the transfer tray 806 reaches above the appropriate trash can 4. The rodless cylinder six 809 is started to drive the turntable 810 to rise. The connecting seat 808 rotates relative to the turntable 810, and the rotating wheel 807 moves along the slide rail 805. The transfer tray 806 tilts, and the garbage falls into the trash can 4 along the transfer tray 806, completing the bucket-changing of the garbage, avoiding the situation that the garbage in some trash cans 4 accumulates too little while the garbage in some other trash cans 4 accumulates too much and causes overflow. When the amount of garbage in the trash can 4 is too much, it can feedback to the external processing center to remind the staff to change the bucket, which is very practical.
