The core of the invention is to provide a grass scrap collecting device, the opening and closing operation of a box door of the grass scrap collecting device is convenient, and the opening and closing state is reliable.
Another core of the invention is to provide a mower comprising the grass chip collecting device.
Referring to fig. 1 to 5, fig. 1 is a schematic view of a lawn mower provided in the present invention; FIG. 2 is a schematic view illustrating an open state of a door of a grass clippings collecting device of the lawn mower provided by the present invention; FIG. 3 is a schematic structural view of a grass clippings collection device provided by the present invention; FIG. 4 is a schematic structural view illustrating an opened state of a door of the grass clippings collecting device according to the present invention; fig. 5 is a partial schematic view of the grass clippings collection device provided by the invention.
The invention provides a grass scrap collecting device, which is used for collecting grass scraps and is mainly arranged in equipment such as a mower, and the grass scrap collecting device at least comprises the following structures: the box body 1, the box door 2, the electric push rod 16, the connecting rod assembly, the locking guide rod 15 and the elastic piece 14.
Wherein, the opening part of box 1 is equipped with open closed chamber door 2, and under 2 open mode of chamber door, the grass bits in the box 1 can be emptyd out, and under 2 closed mode of chamber door, the grass bits in the box 1 are in by the encapsulated situation, and the grass bits can not shifted out.
The electric push rod 16 is a telescopic push rod which can be extended and shortened, and can be an electric cylinder and the like, and is slidably arranged outside the box body 1, and two ends of the electric push rod are respectively connected with the connecting rod assembly and the locking guide rod 15. In the process of stretching, the connecting rod assembly and the locking guide rod 15 can be driven to move.
One end of the connecting rod assembly is connected to a first end of the electric push rod 16, and the other end is connected to the box door 2. When the electric push rod 16 drives the connecting rod assembly to move or rotate, the purpose of driving the box door 2 to rotate or move can be achieved.
One end of the locking guide rod 15 is connected to the second end of the electric push rod 16, and the other end is connected to the lock head 12 for locking the closed state box door 2. The locking guide rod 15 is provided with a fixing ring 13 for limiting the stroke end point of the locking guide rod, and the movement of the locking guide rod 15 is limited by the fixing ring 13 and can be limited in a single direction or in two directions.
The elastic member 14 is provided between the housing 1 and the lock guide 15, and when the lock guide 15 moves relative to the housing 1, the elastic member 14 can be stretched or released.
During the extension and retraction of the electric putter 16, it has at least an initial state, which is defined as the retracted state of the electric putter 16, i.e. the state with the smallest length. In the initial state of the electric putter 16, the elastic member 14 is in a stretched state, or in a limit stretched state.
When the electric push rod 16 extends from the initial state, the connecting rod assembly does not move at first, the elastic member 14 contracts from the stretching state to drive the locking guide rod 15 to move, and after the elastic member moves to a position where the lock head 12 unlocks the door 2, the connecting rod assembly starts to be driven by the electric push rod 16 and opens the door 2.
When the electric push rod 16 retracts to the initial state, the connecting rod assembly is driven by the electric push rod 16 to close the door 2, the locking guide rod 15 moves to the position where the lock head 12 locks the door 2, and the elastic member 14 stretches to store the force.
In the use process, when the door 2 needs to be switched from the closed locking state to the door opening state, the electric push rod 16 is controlled and driven to extend out, the locking guide rod 15 firstly starts to move under the tension of the tension spring, so that the lock head 12 connected with the locking guide rod also moves towards the direction of the door 2 to realize unlocking, and after the movement stroke of the locking guide rod 15 is completed, the residual stroke of the electric push rod 16 is used for continuously pushing the connecting rod assembly to move or rotate so as to realize the door opening process.
It should be noted that the reason why the lock guide 15 can be moved first is that the elastic member is in a stretched state, and the elastic force of the elastic member acts on the lock guide 15, so that the whole of the lock guide 15 and the electric push rod 16 is moved downward by the elastic member 14, and the lock guide 15 is moved downward, that is, the elongation of the electric push rod 16 is completely transferred to the lock guide 15 at this stage.
In addition, after the extension amount of the electric push rod 16 is fully applied and the door 2 is opened, the elastic member 14 is contracted to some extent but is still in a stretched state.
The completion of the movement stroke of the locking guide rod 15 means that the locking guide rod 15 is limited in the movement range of the locking guide rod 15 in the unlocking direction due to the limiting effect of the fixing ring 13, and when the locking guide rod 15 cannot move due to the clamping of the fixing ring 13, the further extension of the electric push rod 16 acts on the connecting rod assembly, so that the connecting rod assembly moves or rotates.
Correspondingly, in the door closing process, firstly, the electric push rod 16 retracts, at this time, the elastic member is in a stretching state, and the locking guide rod 15 cannot move immediately, so that the door 2 in an open state is closed under the action of self gravity and the pulling action of the connecting rod assembly, and after the door 2 is completely closed, the remaining stroke of the electric push rod 16 continuously pulls the locking guide rod 15 to overcome the elastic force of the elastic member 14 to slide in the direction of locking the door 2, and finally, the lock head 12 locks the door 2.
It can be known that, in the operation of the above structure, in the process of opening the door 2, the door 2 is unlocked first and then the opening of the door 2 is controlled, in the process of closing the door 2, the door 2 is closed first, and after the closing operation is completed, the locking operation of the door 2 is controlled.
According to the control system, the opening and closing of the box door and the locking sequence of the box door are controlled only through the operation of the electric push rod 16, the opening and closing operation can be accurately realized, and the stability of the structure is guaranteed. The operation is simple and the stability is strong through the cooperation of the fixing ring 13, the elastic piece 14, the locking guide rod 15 and the electric push rod 16.
