The linkage hooking device has the following functions: in the vertical lifting stage of the garbage can 11, the movable frame 16 is driven to ascend along with the power sliding part 15, so that the pressing plate 12 at the top of the movable frame 16 is prevented from pressing the garbage can 11 to influence weighing; in the stage of overturning and dumping the garbage can 11, the garbage can 11 is separated from the movable frame 16, and in the stage, the power sliding part 15 presses the edge of the garbage can 11 onto the pressing plate 12 to drive the movable frame 16 to move, so that the garbage can 11 is pressed, and the garbage can is prevented from falling or being thrown.
The power sliding part 15 is provided with a bucket hanging bearing part 13; and a force measuring sensor 14 is arranged between the bucket hanging bearing part 13 and the power sliding part 15.
The linkage hooking device is a device which drives the movable frame 16 to move along with the power sliding part 15 when the garbage bin 11 vertically rises.
The linkage hooking device comprises a fixed end 42 and a swinging end 44; the fixed end 42 is fixed on the movable frame 16; the swinging end 44 is connected with the fixed end 42 through a pin shaft 43; a cross bar 45 is arranged at one end of the swinging end 44 away from the fixed end 42; the cross bar 45 is lapped on the guide lower support part 25 or a part connected with the guide lower support part 25; the swing end 44 is connected to the movable frame 16 by a spring 46.
The linkage hooking device comprises an elastic body 54; one end of the elastic body 54 is fixed on the movable frame 16, and the other end is provided with a cross bar 45; the cross bar 45 is lapped on the guide lower support 25 or a portion connected to the guide lower support 25.
The linkage hooking device comprises a cross rod 45 arranged on the movable frame 16 and a slide block 62 arranged on the guide lower support part 25; the slider 62 can slide back and forth relative to the guide lower support portion 25.
The utility model adopts the mode that the characteristic that a certain included angle is generated between the guide lower supporting part 25 and the movable frame 16 when the garbage bin is turned is utilized, and the linkage hooking device is additionally arranged on the guide lower supporting plate 25, the movable frame 16 or the part connected with the movable frame 16, so that the movable frame 16 moves along with the power sliding part 15 in the vertical rising stage of the garbage bin 11, and the pressing plate 12 of the movable frame 16 can not contact the garbage bin 11 in the process; in the process of overturning and dumping the garbage can 11, due to the included angle generated between the movable frame 16 and the guide lower supporting plate 25, the linkage hooking device can be separated from the guide lower supporting part 25 or the movable frame 16, so that the movable frame 16 is separated from the synchronous motion of the power sliding part 15, and the pressing plate 12 of the movable frame 16 can press the edge of the garbage can 11;
in practical application, there are multiple embodiments to realize that bucket lifting rises stage movable frame 16 and clamp plate 12 and do not press the bucket edge, and upset material pouring stage clamp plate 12 presses the purpose on firm bucket edge, and all utilize when turning over the bucket the characteristics that can produce certain contained angle between guide lower support portion 25 and the movable frame 16 to install additional similar take with or connecting device, all with the utility model discloses it is same in essence.
The first embodiment is as follows: the linkage hooking device is in a swing rod form;
as shown in fig. 4, the fixed end 42 is welded to the movable frame 16, and is connected to the swing end 44 via a pin 43, and the other end of the swing end 44 is provided with a cross bar 45, and the cross bar 45 is lapped on the upper surface of the guide lower support portion 25. The swing end 44 is also provided with a spring 46 that is pulled to the movable frame 16. When the lifting phase of the pail is started, the driving device 27 drives the power sliding part 15 to lift, and the power sliding part 15 drives the guiding lower support part 25 to move upwards. The guide down support 25 lifts the cross bar 45, thereby lifting the movable frame 16. In order to make the stress uniform and increase the bearing capacity, a set of linkage hooking device can be respectively arranged at the left side and the right side of the movable frame 16. When the movable frame 16 moves to the top of the guide rail 17, the guide rail 17 starts to turn, and the movable frame 16 gradually turns the garbage can 11 in motion. At this time, the tail ends of the movable frame 16 and the lower guide supporting part 25 start to be separated, the cross rod 45 slides from the upper surface of the lower guide supporting part 25 to complete tripping separation, the movable frame 16 loses lifting of the lower guide supporting part 25 and stops moving until the power sliding part 15 drives the edge of the garbage can 11 to prop against the pressing plate 12, the movable frame 16 is continuously driven to move, and the pressing plate 12 presses the edge of the garbage can 11 in the process, so that the garbage can 11 can be prevented from falling. And after the garbage is poured, starting the return stroke. The trash can 11 is changed from the dumping state to the upright state. At this time, the front surface of the lower guide support 25 first contacts the cross bar 45 due to the bending of the top of the guide rail 17. The normal return stroke movement is not affected because the swinging end 44 can swing. When the garbage can 11 falls to the ground and the movable frame 16 stops moving, the power sliding part 15 will continue to move downwards for a certain distance, in this process, the swing end 44 will pull the cross rod 45 back to the upper surface from the front surface of the lower guide support part 25 under the tension of the tension spring 46, the whole reset action is completed, and the garbage in the next can be dumped.
Example two: the linkage hooking device is in an elastic rod form;
as shown in fig. 5, the elastic body 54 is fixed to the movable frame 16 at one end and provided with the cross bar 45 at the other end. The whole working principle is similar to that of the first embodiment, the fixed end 42 and the swinging end 44 are replaced by the elastic body 54 which is elastic per se, and the pin shaft 43 and the spring 46 can be omitted.
In the third embodiment, as shown in fig. 6, a slide block 62 is provided on the front surface of the guide lower support portion 25, the slide block 62 is elastically mounted on the guide lower support portion 25, the slide block 62 can be extended and contracted on the front surface of the guide lower support portion 25, and the cross bar 45 is provided on the movable frame 16. When the bucket is raised, the slide block 62 exerts an upward force on the cross bar 45 to lift the movable frame 16. By mounting the slide block 62 and the cross bar 45 in place, it is achieved that the pressing plate 12 does not press the rim of the receptacle 11 during the lifting phase of the pail. When the movable frame 16 runs to the bent portion at the top of the guide rail 17, the movable frame 16 will gradually turn the barrel in motion. At this time, the movable frame 17 and the guide lower support portion 25 start to be separated, and the cross bar 45 slides off the slider 62, thereby completing the releasing and separating. And after the garbage is poured, starting the return stroke. The trash can is changed from a dumping state to a vertical state. In the return process, the front end face of the sliding block 62 firstly contacts the cross rod 45, when the garbage can 11 falls to the ground, and after the movable frame 16 stops moving, the power sliding part 15 can still continue to move downwards for a certain distance, in the process, because the sliding block 62 can slide back and forth on the surface of the guide lower supporting part 25, the cross rod 45 can slide through the front part of the sliding block 62, the whole reset action is completed, and the next garbage can be dumped.
In practical application, the movable frame 16 and the pressing plate 12 can not press the barrel edge in the ascending stage of the lifting barrel, the pressing plate 12 can firmly press the barrel edge in the overturning and pouring stage,
the above-mentioned embodiments should not limit the present invention in any way, and all the technical solutions obtained by adopting equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
