Technical Field

[0001] The utility model relates to the technical field of garbage bins, in particular to an automatic garbage barrel changing device. Background Art

[0002] Trash bins are a very common type of garbage disposal tool in our daily life. At present, the country advocates garbage classification and has developed large-scale garbage classification bins, garbage rooms and other garbage disposal equipment. The internal space of garbage bins and garbage rooms is very large and can accommodate various garbage disposal machines to pre-process the garbage in the bins.

[0003] Generally, there is one garbage can corresponding to one garbage delivery port inside a garbage bin. When throwing garbage, it is impossible to observe the remaining space inside the garbage can and throw it in arbitrarily, resulting in some garbage cans being full and overflowing, while some garbage cans still have a lot of space left, causing a waste of resources and space, polluting the environment, and maintenance workers have to recycle and clean the garbage cans frequently.

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] like Figure 1 As shown, an automatic garbage barrel changing device of the utility model comprises a bracket 1, a garbage bucket 4, a ball screw 3, a slider 5 arranged on the ball screw 3, a motor 2 for driving the ball screw 3 to rotate, a position limiting tilting device 1 arranged in the middle section of the bracket 1, and a position limiting tilting device 2 arranged at the rear end of the bracket. The ball screw 3 is located on one side of the bracket 1, and both ends are fixed on the bracket 1 through a support seat 12 respectively, and the end of the ball screw 3 is connected to the motor 2; the front end of the garbage bucket 4 is connected to the slider 5, and the garbage bucket 4 is driven to move forward and backward through the slider 5. The bracket 1 is provided with an infrared sensor, an inductive sensor, and a PLC controller 13, and the PLC controller 13 is connected to each sensor, and is connected to the motor 2 and the push rod motor 8; the infrared sensor includes an infrared sensor 14, an infrared sensor 2 17, an infrared sensor 3 18 and an inductive sensor, and each infrared sensor is sequentially arranged above each corresponding garbage bin, corresponding to the number of garbage bins, and the inductive sensor is arranged on the garbage inlet door, and the inductive sensor is an infrared sensor or an ultrasonic sensor.

[0029] like Figure 2 As shown, the bottom of the garbage hopper 4 is crescent-shaped, and a rotating shaft 7 is connected to the front end of the garbage hopper 4. One end of the rotating shaft 7 is connected to the slider 5, and the other end is provided with a roller 6. Rollers 6 are respectively provided on both outer sides of the garbage hopper 4 to facilitate the garbage hopper 4 to slide on the bracket 1.

[0030] like Figure 3 and Figure 4 As shown, the limit tilting device includes an L-shaped lifting limit rod 11, a support rod 15, and a push rod motor 8; one end of the lifting limit rod 11 is hinged to the bracket 1, and the other end is provided with a limit roller 9 to facilitate the tilting and sliding of the garbage bin 4; one end of the support rod 15 is connected to the push rod motor 8 through a connecting block, and the other end is connected to one side of the hinged bracket of the lifting limit rod 15, and the support rod 15 is driven by the push rod motor 8 to lift and lower the lifting limit rod 11.

[0031] like Figure 1 As shown, the second limit tilting device is arranged at the rear end of the bracket 1 (the rightmost end in the figure), including a fixed limit rod 16. The fixed limit rod 16 is a straight rod structure, one end of which is fixedly installed at a preset height position on the right end of the bracket 1, and the other end is provided with a limit roller 2 10 to facilitate the tilting and sliding of the garbage bin.

[0032] The utility model takes the automatic replacement of three garbage bins as an implementation case.

[0033] Embodiment 1:

[0034] Install the device in the trash can with the opening located at Figure 5 At the initial operation, when the induction sensor detects a signal when the slot door is opened, the PLC controller 13 controls the automatic barrel changing device to start working. Figure 5 As shown, at this time, the garbage hopper 4 is located at the input port, and the lifting limit rod 11 is initially in the down state. When the garbage falls into the garbage hopper 4 and the set time is reached (5-10s), the PLC controller 13 starts the motor 2 to rotate forward to drive the ball screw 3 to move, thereby driving the garbage hopper 4 to move rightward to the rightmost side (the slider 5 slides rightward to drive the garbage hopper shaft 7 to move rightward), as shown in FIG. Figure 6 As shown, when the garbage bucket 4 reaches the fixed limit rod 16 on the far right of the bracket 1, the garbage bucket 4 continues to slide to the right under the action of the ball screw 3, thereby sliding upward along the limit roller 2 10 of the fixed limit rod 16. During the upward sliding process of the garbage bucket 4, the garbage in it falls down along the garbage bucket into the garbage bin at the far right bottom. When the working stroke of the ball screw 3 reaches the first stroke set by the PLC controller 13, the PLC controller 13 controls the motor 2 to reverse, and the ball screw 3 drives the garbage bucket 4 to move to the left to stop at the injection port, waiting for the next start signal.

[0035] Embodiment 2:

[0036] When the infrared sensor 18 senses that the rightmost trash can is full, when the trash hopper 4 returns to the left to the slot, the PLC controller 13 starts the push rod motor 8 to pull back, pulling the support rod 15 to tilt upward so that the lifting limit rod 11 is lifted upward; when the slot is opened, the induction sensor transmits a signal to the PLC controller 13, and the garbage falls into the trash hopper 4 until the set time (5-10s) is reached. The PLC controller 13 starts the motor 2 to rotate forward to drive the ball screw 3 to move, thereby driving the trash hopper 4 to move to the right to the middle lifting limit rod 11 position, such as Figure 7 As shown, the garbage hopper 4 continues to slide to the right under the action of the ball screw 3, thereby sliding upward along the limit roller 9 of the lifting limit rod 11. During the upward sliding process of the garbage hopper 4, the garbage in it falls downward along the garbage hopper 4 into the garbage bin in the middle and lower part. When the working stroke of the ball screw 3 reaches the second stroke set by the PLC controller 13, the PLC controller 13 controls the motor 2 to reverse, and the ball screw 3 drives the garbage hopper 4 to move to the left to the injection port and stop, waiting for the next start signal.

[0037] Embodiment three:

[0038] When the trash can infrared sensor 17 also senses that the trash can below is full, the PLC controller 13 controls the motor 2 to stop working, and the trash bucket 4 is always in a tilted state on the lifting limit rod 11 in the middle of the bracket 1. When the injection port is opened, the garbage will fall directly into the trash can on the far left below the injection port.

[0039] When the infrared sensor 14 senses that the trash bin below is full, the PLC controller 13 displays the information on the display screen outside the trash bin or uses wireless communication to inform the staff to centrally empty the trash bin. The emptied trash bins are placed in the trash bin. At this time, the staff activates the system reset button, and the trash bucket 4 returns to the leftmost position under the drive of the ball screw 3. At the same time, the PLC controller 13 activates the push rod motor 8 to extend outward, pushing the support rod 15 to tilt downward so that the lifting limit rod 11 falls downward to the bottom of the bracket 1, thereby starting a new round of automatic bucket replacement process.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
