In one exemplary embodiment, the capping device includes: a first top cover 12 and a second top cover 13 having an open state and a closed state, and the first top cover 12 and the second top cover 13 together cover the feed opening 11 at the top of the garbage can body 1 in the closed state, the opening means referred to herein refers to a fully open state; the first-stage connecting rod mechanism and the second-stage connecting rod mechanism are arranged on the box body 1 and are respectively used for driving the first top cover 12 and the second top cover 13 to rotate and open and close; and the driving mechanism 2 is connected with the first-stage connecting rod mechanism and is used for driving the first-stage connecting rod mechanism to move so as to open and close the first top cover 12 and simultaneously driving the second-stage connecting rod mechanism to link so as to synchronously open and close the second top cover 13. The drive mechanism 2 is a power source for opening and closing the first top cover 12 and the second top cover 13.
The top cover device of the embodiment of the application has at least one of the following advantages:
(1) The first top cover and the second top cover realize the opening and closing of the feeding port in a rotating mode, the requirement on the matching installation precision of the top cover and the box body is low, the problem that movement clamping stagnation occurs when the top cover is deformed or garbage exists at the top cover can be avoided, noise or abnormal sound generated when the top cover moves is reduced, and the device can be suitable for working under a harsher garbage collection and transportation environment.

In some embodiments, as shown in fig. 2, the first top cover 12 and the second top cover 13 are disposed along the longitudinal direction of the case 1 in the closed state. For example, both the first top cover 12 and the second top cover 13 may be rectangular plate-like structures. The split type top cover can obviously reduce the height of the whole automobile after the top cover is opened, so that the problem that the top cover is limited by the environment in the use process is solved, and the environmental adaptability is improved. When the first top cover 12 and the second top cover 13 are identical in size in the longitudinal direction of the case 1, the height of the opened top cover can be reduced to the maximum.
In some embodiments, as shown in fig. 1, the second stage linkage is connected to the first top cover 12 to drive the second stage linkage to move when the first top cover 12 is opened and closed, so as to open and close the second top cover 13 synchronously. Under the condition that the whole first-stage connecting rod mechanism is positioned at one side of the first top cover 12, the structure can be simplified by connecting the second-stage connecting rod mechanism with the first top cover 12, and a special-shaped structure is not required to be additionally arranged for connecting the second-stage connecting rod mechanism with part of rod pieces in the first-stage connecting rod mechanism; in addition, the first top cover 12 is convenient for arranging a hinging seat, so that stable and reliable connection can be realized, and the movement of the second-stage connecting rod mechanism can be more stable and reliable. Alternatively, the second stage linkage may be connected to a portion of the rods in the first stage linkage.
As shown in fig. 1, the feed opening 11 is provided along a part of the length of the top of the tank 1 and is provided near one side of the tank 1 in the longitudinal direction, for example, near the right side in fig. 1. In the open state, the first top cover 12 and the second top cover 13 are both positioned at one end of the feeding port 11 close to the closed area of the box body 1, and the first-stage link mechanism is arranged in the closed area at the top of the box body 1 and can be integrally positioned at one side of the first top cover 12 far away from the second top cover 13; the second-stage link mechanism is positioned in the area of the feed port 11, and the main body part is positioned on one side of the second top cover 13 away from the first top cover 12. In the closed state, the second-stage linkage is located within the case 1.
According to the embodiment, the space at the top of the box body 1 can be reasonably utilized, the design size of the feed port 11 is increased as much as possible, the two-stage movement mechanism is prevented from interfering the movement of the top cover, the structure of the top cover device can be simplified, and the movement reliability is improved.
Further, in the fully opened state, the first top cover 12 and the second top cover 13 are parallel to each other and reach a minimum distance, so as to occupy the space of the feed port 11 as little as possible.
Further, under the state of being fully opened, the first top cover 12 and the second top cover 13 can also incline towards the closed area at the top of the box body 1, so that the material inlet 11 is exposed as much as possible, the top cover is prevented from shielding the material inlet 11, the garbage truck can be used for charging more once, garbage is prevented from being scattered outside the material inlet, and secondary environmental pollution is avoided.
In some embodiments, as shown in fig. 1, one end of the first top cover 12 near the closed area of the box 1 is directly rotatably disposed at the top of the box 1, and the first-stage link mechanism includes a first rod 3 and a second rod 4, where the first end of the first rod 3 is hinged to the top of the box 1, for example, hinged to a middle position of the closed area of the top of the box 1 in a longitudinal direction, and two ends of the second rod 4 are respectively hinged to the second end of the first rod 3 and an outer side surface of the first top cover 12.
Therefore, the top of the box body 1, the first rod piece 3, the second rod piece 4 and the first top cover 12 form a four-bar mechanism together, and the first top cover 12 can be stably driven to rotate so as to realize opening and closing. And the overall height of the four-bar linkage mechanism can be reduced in the process of closing the first top cover 12, so that the overall height of the garbage truck in a non-working parking state or a running state can be reduced, and the limitation on the garbage truck in the parking or running process can be reduced.
Further, the driving mechanism 2 is a telescopic member such as a hydraulic cylinder, an air cylinder, an electric push rod, or the like. The first end of the telescopic component is hinged to the box body 1 at a position located on the outer side of the first rod piece 3, and the second end of the telescopic component is hinged to the first rod piece 3 and used for driving the first rod piece 3 to swing through telescopic driving so as to drive the first top cover 12 to open and close through the second rod piece 4. Alternatively, the driving mechanism 2 may also output a rotational motion to drive the first pin 3 to rotate. In this embodiment, the driving mechanism 2 is provided, so that the first top cover 12 can be automatically opened and closed, and a large driving force can be obtained by adopting the telescopic member, so that the top cover device can be reliably opened and closed.
Preferably, the first end of the telescopic member is hinged to the end of the casing 1 longitudinally distant from the mouth 11, so that a greater pushing force is obtained.
Preferably, the second rod 4 may be hinged to a middle region of the first top cover 12 in the longitudinal direction, so as to obtain a preferred driving position, and can reliably push the first top cover 12 to open and close.
Preferably, a protrusion is provided on the first rod 3 at a position hinged to the telescopic member to provide a hinge point, and this structure makes it easier to apply a force to the first rod 3 to open the first top cover 12 when the top cover is switched from the closed state to the open state, preventing occurrence of a movement dead point.
Preferably, the second rod 4 is telescopic in length. By designing the second rod 4 to be of a structure with an adjustable length, the first top cover 12 can be reliably closed in place by adjusting the second rod 4 to be of a proper length, the tightness of the box body 1 is improved, and dust or smell in garbage can be prevented from escaping.
Referring to fig. 2, by adjusting the second rod 4 to a suitable length, in the closed condition, the first rod 3 and the second rod 4 are collinear, and the telescopic member is located above the first rod 3, the telescopic member, the first rod 3 and the second rod 4 being substantially in the same horizontal plane. The structure can furthest reduce the overall height of the box body 1 in a non-working parking state or a running state, and reduce the limitation of the garbage truck in the parking or running process.
In order to further reduce the height, the closed area of the top of the case 1 may be made lower than the upper surfaces of the first and second top covers 12 and 13 in the closed state so that the first-stage linkage part is located within the height between the closed area of the top of the case 1 and the top cover in the closed state.
In some embodiments, as shown in fig. 1, the second-stage linkage mechanism includes a rotating arm 10, a first end of the rotating arm 10 is rotatably connected to an area corresponding to the feeding port 11 in the box 1, and a second end of the rotating arm 10 is fixedly connected to the second top cover 13, so that the second top cover 13 swings to realize opening and closing through rotation of the rotating arm 10.
In this embodiment, the second top cover 13 is not directly rotatably disposed on the case 1, but is rotatably disposed by the rotary arm 10, so that the second top cover 13 can be moved longitudinally while being opened and closed, not only can the second top cover 13 close the target position of the feed inlet 11 in the closed state, but also the target position is far away from the position where the first top cover 12 is rotatably connected with the case 1, and can be moved to a position close to the first top cover 12 in the open state, thereby reducing the occupied space.
Still referring to fig. 1, the second end of the rotary arm 10 is connected to an end of the second top cover 13 longitudinally adjacent to the closed area of the cabinet 1. In the open state, the second end of the rotary arm 10 is connected to the position of the second top cover 13 near the bottom end, and this arrangement mode can reduce the set length of the rotary arm 10, and make the rotary arm 10 near the opened second top cover 13 at the fixed position of the box 1, so as to reduce the influence of the rotary arm 10 on the feeding port 11 as much as possible, and realize smooth feeding.
Further, the second-stage linkage mechanism further comprises a third rod member 9, a first end of the third rod member 9 is hinged to the first top cover 12, and a second end of the third rod member is hinged to the rotating arm 10, and the second end of the third rod member is used for driving the rotating arm 10 to rotate through the third rod member 9 when the first top cover 12 rotates, so that the second top cover 13 and the first top cover 12 are synchronously opened and closed. The third rod piece 9, the first top cover 12, the box body 1 and the second top cover 13 form another group of four-bar linkage, and the four-bar linkage is linked with the first top cover 12 to realize the opening and closing of the second top cover 13. The first top cover 12 and the second top cover 13 are synchronously opened and closed through the linkage of the two groups of four-bar structures, so that the feed inlet 11 is closed and opened.
In this embodiment, the third lever 9 is used to transmit the driving force received by the first-stage link mechanism to the second-stage link mechanism, and the linkage of the two-stage link mechanism can be achieved by a simple structure to achieve synchronous opening and closing of the first top cover 12 and the second top cover 13. Furthermore, since the first top cover 12 is stable in movement, the third rod 9 is hinged to the first top cover 12, and the stability of movement of the second top cover 13 can also be improved.
Preferably, the third bar 9 is telescopic in length. By designing the third rod member 9 to have an adjustable length, the second top cover 13 can be reliably closed in place by adjusting the length of the third rod member 9 to be proper, so that the tightness of the box body 1 is improved, and dust or smell in garbage can be prevented from escaping.
Still referring to fig. 1, the rotating arm 10 is of an L-shaped structure, an included angle at a bending position of the L-shaped structure is an obtuse angle, and the second end of the third rod 9 is hinged at the bending position of the L-shaped structure.

Preferably, the extension 131 may be provided at the free end of the first top cover 12 and along the lateral direction of the first top cover 12 for overlapping the outer surface of the second top cover 13 in the closed state. The embodiment can prevent dust and smell in the garbage from escaping, and avoid secondary pollution to the environment.
More specifically, a first hinge seat 5 is provided at a longitudinal end position of the closed area of the case 1 for hinge-connecting the telescopic member; a second hinging seat 6 is arranged at the middle position of the closed area of the box body 1 along the longitudinal direction and is used for hinging the first rod piece 3; a third hinging seat 7 is arranged at the middle area of the outer side of the first top cover 12 along the longitudinal direction and is used for hinging the second rod piece 4; a fourth hinging seat 8 is arranged at a position of the feeding port 11 close to the top sealing area of the box body 1 and is used for hinging the first top cover 12 on the box body 1, and as shown in fig. 3, a connecting part 15 is a part of the fourth hinging seat 8 connected on the first top cover 12; a fifth hinging seat 14 is arranged below the feeding port 11 in the box body 1 and is used for hinging the rotary arm 10.
