DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-4 A double bucket cylinder synchronous control device comprises a bracket 1 and a hopper 2 installed at the middle end of the bracket 1, a bucket outlet pipe 3 is installed at the bottom end of the hopper 2, a middle frame 4 is installed horizontally at the middle end of the bracket 1, an inner frame 5 is provided at the middle end of the middle frame 4, the bucket outlet pipe 3 is located inside the inner frame 5, a support net 6 is installed between the outer side of the middle frame 4 and the inner side of the inner frame 5, and a control box 7 is installed at the bottom end of the support net 6.

[0023] The two sides of the outer surface of the bucket outlet pipe 3 are hingedly mounted with bucket lobes A31 and bucket lobes B32 respectively.

[0024] An L-shaped short plate A51 and an L-shaped short plate B52 are respectively installed on both sides of the same end of the built-in frame 5, and an auxiliary closed bucket proximity switch 54 and a main closed bucket proximity switch 56 are respectively installed on the upper ends of the L-shaped short plate A51 and the L-shaped short plate B52. The auxiliary closed bucket proximity switch 54 and the main closed bucket proximity switch 56 are set to limit the rotation of the bucket petal A31 and the bucket petal B32.

[0025] The outer surface of the hopper 2 is symmetrically installed with an auxiliary push rod 21 and a main push rod 22, and the movable end of the auxiliary push rod 21 is installed on one side of the bucket A31, and the movable end of the main push rod 22 is installed on the bucket B32. The auxiliary push rod 21 and the main push rod 22 are used to open and close the bucket A31 and the bucket B32.

[0026] An auxiliary closing bucket steel bar 55 is installed on the outer side of the bucket A31 and close to the L-shaped short plate A51, and a main closing bucket steel bar 57 is installed on the outer side of the bucket B32 and close to the L-shaped short plate B52. The auxiliary closing bucket steel bar 55 and the main closing bucket steel bar 57 are used to limit the closing of the bucket A31 and the bucket B32.

[0027] An L-shaped long plate 53 is installed on the inner wall of the built-in frame 5 and on one side of the L-shaped short plate B52. A limit proximity switch 58 is installed on the upper end of the L-shaped long plate 53 to limit the opening of the bucket lobe A31 and the bucket lobe B32.

[0028] The position of the main bucket closing proximity switch 56 is lower than the position of the limit proximity switch 58, which controls the opening and closing limits of the bucket lobe A31 and the bucket lobe B32 respectively.

[0029] The control box 7 is electrically connected to the auxiliary bucket closing proximity switch 54 , the main bucket closing proximity switch 56 , the limit proximity switch 58 , the auxiliary push rod 21 and the main push rod 22 .

[0030] In this embodiment: by adding a secondary bucket closing proximity switch 54 and a main bucket closing proximity switch 56, the model is Ni15-M30-AZ3X / S90, first the bucket flap A31 and the bucket flap B32 are closed to the center position, one hydraulic push rod is used as the main push rod 6, and the other is used as the secondary push rod 7, and the secondary bucket closing steel bar 55 is welded on the bucket flap A31 connected to the secondary push rod 7 to correspond to the secondary bucket closing proximity switch 54, and the main bucket closing steel bar 57 is welded on the bucket flap B32 connected to the main push rod 6 to set the main bucket closing proximity switch 5 6. The bucket flaps A31 and B32 are opened to the maximum. The main closing bucket steel bar 57 welded on the main push rod 6 connecting the bucket flap B32 corresponds to the limit proximity switch 58. The main push rod 6 and the auxiliary push rod 7 are directly controlled by the opening and closing buttons (existing components) in the control box 7. When the stop button is pressed, any one of the main push rod 6 and the auxiliary push rod 7 reaches the limit. The one that reaches the limit stops working first, and the one that has not reached the limit will continue to work until it reaches the limit, and the closing of the bucket flaps A31 and B32 is completed.

[0031] Working principle: By utilizing the auxiliary bucket closing proximity switch 54 and the main bucket closing proximity switch 56, when starting, the auxiliary push rod 21 and the main push rod 22 on both sides are guaranteed to have the same running stroke and time, ensuring that the bucket flap A31 and the bucket flap B32 are opened in balance. When closing the bucket, the auxiliary bucket closing proximity switch 54 and the main bucket closing proximity switch 56 are utilized to stop when reaching the limit position, avoiding improper closure of the bucket door and inconsistent strokes of the main push rod 6 and the auxiliary push rod 7, ensuring effective cargo release and extending the service life of the main push rod 6 and the auxiliary push rod 7.
