Detailed Description
Referring to fig. 1-4, a garbage truck lifting box feeding mechanism comprises a garbage truck body 1, a rear section of the garbage truck body 1 is a garbage bin storage area 2, a rear section of the garbage bin storage area 2 is rotatably provided with a first cylinder 3, a top end of a first piston rod 4 of the first cylinder 3 is hinged to a connecting rod 5, one end of the connecting rod 5, which is far away from the first piston rod 4, is provided with a hook, a front section of the garbage bin storage area 2 is hinged to a second cylinder 6, a top end of a second piston rod 7 of the second cylinder 6 is hinged between two ends of the first cylinder 3, a sliding part is axially and slidably arranged on the connecting rod 5, a connecting plate 8 is radially arranged on the outer peripheral surface of one end of the sliding part, which is close to the first piston rod 4, one end of the connecting plate 8, which is far away from the sliding part, is hinged between two ends of the first piston rod 4, and a limiting part 17 facing the first piston rod 4 is arranged on one surface of the connecting plate 8 facing the sliding part, the axial line of the first cylinder 3, the axial line of the second cylinder 6 and the axial line of the connecting rod 5 are in the same plane.
In this embodiment, in operation, the second cylinder 6 on the garbage truck body 1 drives the second piston rod 7 to extend, so as to jack up the first cylinder 3, so that the first cylinder 3 rotates to the outside of the garbage can storage area 2 relative to the garbage can storage area 2 until the hook sags, and then after the hook hooks the reserved hung part on the garbage can, the second cylinder 6 contracts, the second piston rod 7 retracts into the second cylinder 6, and the garbage can is located in the garbage can storage area 2. After the retraction of the second piston rod 7 is finished, at the moment, the position of the dustbin located in the dustbin storage area 2 is corrected through the first cylinder 6, the first cylinder 6 is parallel to the upper surface of the dustbin storage area 2, at the moment, the first piston rod 4 in the first cylinder 3 is extended, the connecting rod 5 and the hook are both arranged at the top end of the first piston rod 4, and due to the correction, the extension and retraction lengths of the first piston rod 4 are smaller, so that the dustbin moves along with the extension of the first cylinder 3 in the extension process of the first cylinder 3 until the dustbin is corrected to the preset position in the dustbin storage area 2. Due to the arrangement of the first cylinder 3, in the process that the dustbin enters the dustbin storage area 2, due to the arrangement of the first cylinder 3, the second cylinder 6 and the connecting rod 5, in the process that the dustbin enters the dustbin storage area 2, firstly, the hook lifts one end of the dustbin, then the dustbin is pulled until the bottom surface of the dustbin is attached to the side wall of the first cylinder 3, in the process, the bottom surface of the dustbin is not cut and rubbed with the rear end of the garbage truck body 1, and therefore the problem that the bottom wall of the dustbin is always cut and rubbed with the rear end of the garbage truck body 1 in the process that the dustbin is lifted onto the garbage truck body 1 by a conventional garbage truck is solved, and the service life of the dustbin is shortened due to the fact that a simple dragging device is adopted.
Wherein, in order to reduce the friction to which the bottom surface of the waste bin is subjected during the extension of the second piston rod 7 correcting the position of the waste bin in the storage area 2 of the waste bin, as a preferred mode, the upper surface of the storage area 2 of the waste bin is provided with a plurality of wheels 9, and the axes of the wheels 9 are perpendicular to the first cylinder 3.
As a preferable mode, a rotating shaft at the hinged position of the first cylinder 8 and the garbage can storage area 2 is perpendicular to the driving direction of the garbage truck body 1, so that the purpose is to enable the garbage can to enter the garbage can storage area 2 from the rear end of the garbage truck body 1, and therefore the garbage can storage area is more in line with the conventional habit and is convenient for practitioners to understand; of course, the garbage can enter the garbage can storage area 2 from the left side or the right side of the garbage truck body 1, and only in the mode, the width value of the garbage can is small, so that when the garbage truck body 1 is put on one end of the garbage can in the process of lifting the garbage can, the slope of the inclination of the garbage can is too large, the garbage can is inconvenient to use, and the garbage in the garbage can easily fall off.
Preferably, the first cylinder 3 is provided with a roller 10 on the side opposite to the garbage can storing area 2, and the axis of the roller 10 is perpendicular to the traveling direction of the garbage truck body 1, so that the friction between the bottom surface of the garbage can and the first cylinder 3 is reduced when the second piston rod 7 extends to correct the position of the garbage can in the garbage can storing area 2.
As a preferable mode, one surface of the first cylinder 3, which faces away from the garbage can storing area 2, is a plane, and the width of the surface of the first cylinder 3, which faces away from the garbage can storing area 2, is greater than half of the width of the garbage can storing area 2, so that the garbage can is prevented from being turned left and right when the garbage can is attached to the first cylinder 3, and the first cylinder 3 can be well attached to the bottom surface of the garbage can due to the plane; the purpose of the width of the side of the first cylinder 3 facing away from the waste bin storing area 2 being greater than half the width of the waste bin storing area 2 is to enable the first cylinder 3 to be stored in the waste bin storing area 2 when not in use, and to enable the first cylinder 3 to provide uniform support for the bottom surface of the waste bin when the first cylinder 3 needs to be used, thereby reducing the pressure on the bottom surface of the waste bin.
As a preferable mode, the hook comprises a hook body 11, a notch is formed in one edge of an opening end of the hook body 11, a movable plate 13 is rotatably connected in the notch, one end of the movable plate 13 is close to the other opening edge of the opening end of the hook body 11, a protrusion 15 is formed in one side of the movable plate 13, which is opposite to the hook body 11, and is close to the rotary connection position, and a falling object 14 is fixedly connected to the protrusion 15; therefore, when the garbage can is hooked by the hook body 11, the movable plate 13 gives way to the opening of the hook body 11, and after the garbage can is hooked, the opening of the hook body 11 can be sealed, so that the phenomenon that the preset hooked part on the garbage can falls off from the hook body 11 is avoided.
Preferably, the sliding member is a rod sleeve 16, and the rod sleeve 16 is coaxially sleeved between two ends of the connecting rod 5, so that when the connecting rod 5 is used for lifting the trash bin, an angle between the connecting rod 5 and the first piston rod 4 under the action of gravity can be smaller than a right angle, and a reserved hooked position on the trash bin can be easily hooked.
As a preferable mode, as shown in fig. 4, two connecting plates 8 are provided, and the two connecting plates 8 are respectively disposed at two sides of the connecting rod 5, and one surface of each of the two connecting plates 8 facing the connecting rod 5 is commonly connected to two ends of the same limiting member 12; its purpose is in order to make the connecting plate have sufficient intensity, the angle of restriction connecting rod 5 and first piston rod 4 pivoted, and the angle of avoiding connecting rod 5 pivoted exceeds preset angle.
