After engaging, when the traveling motor 240 is activated, the entire horizontal conveying mechanism 2 is driven to move toward the other end of the horizontal guide rail 20 along the direction of the rack.

The reversing mechanism 3 includes a lifting cylinder 30, a rotating cylinder 31, a vertical guide rail 32 and a connecting mounting plate 33. The lifting cylinder 30 is mounted on the connecting support plate 33 and the telescopic shaft is vertically oriented towards the direction of the base frame support 11 (ie, vertical). straight down), the vertical guide rails 32 are located on both sides of the lifting cylinder 30 respectively, one end of the vertical guide rail 32 is slidably mounted on the connecting support plate 22 through the bearing seat, and the connecting mounting plate 33 is rigidly connected to the vertical guide rail 32 The other end of the rotating cylinder 33 is fixed on the telescopic shaft end of the lifting cylinder 30, the installation surface of the rotating cylinder 31 is fixed on the connecting mounting plate 33, and the rotating working surface of the rotating cylinder 31 is installed with the overturning hopper mechanism 4, When the lift cylinder 30 is telescopic, it drives the rotary cylinder 31 and the overturning hopper mechanism 4 to move up and down. During the up and down movement, the connecting mounting plate 33 moves up and down with the telescopic shaft of the lift cylinder 30, and its vertical guide rail 32 acts as an auxiliary circuit support. , to prevent the rotating cylinder 31 and the overturning hopper mechanism 4 from being skewed when lifting and lowering, so that they can perform linear lifting displacement.

The turning hopper mechanism 4 includes a turning cylinder 40, a hopper frame 41 and a turning hopper 42.

Preferably, the rotation angle of the rotating cylinder 31 is 180°.

In the preferred embodiment of this design, as shown in FIG. 7 , the turning bucket 42 is in the shape of a dustpan and bucket, the hopper frame 41 is in the shape of a door, and hinge shafts 44 are fixed on both sides of the bucket body of the turning bucket 42 , the hinge shaft 44 is rotated and installed on the open lower end of the door-shaped hopper frame 41, and a U-shaped beam 411 is extended and fixed on the horizontal beam 410 of the door-shaped hopper frame 41 away from the side where the turning bucket 42 is installed, and the turning cylinder 40 The tail of the cylinder body is hinged on the U-shaped beam 411 through the pin shaft 412, the overturning cylinder 40 is fixed in an inclined shape, and the end of its telescopic shaft is fixed on the back of the dustpan bucket-shaped overturning bucket 42. When the overturning cylinder 40 is in a retracted state, The scoop mouth of the tipping bucket 42 is inclined upward. The reason why the overturning bucket 42 is designed in the shape of a dustpan and bucket is for the convenience of discharging materials. It is only necessary to extend and retract the overturning cylinder 40 for a certain stroke to make the overturning bucket 42 tilt, and then the valve slides down quickly, and no individual valve is left in the overturning bucket 42. Among them, if it is designed as a rectangular box, the installation method of the overturning cylinder 40 is more complicated.

After the valve can be dumped more quickly, it can quickly return to the next round of material transfer.

As shown in Fig. 10 and Fig. 11, in the preferred embodiment of the design, because the size of the storage hoppers may be different between the production equipments in the production workshop, some of them are designed with the overturning hopper 42 in order to transport more at one time. The size of the storage bins at the two positions is different, even smaller than that of the overturning bucket, so the following structure can be designed to adjust the size of the pouring opening of the overturning bucket 42 to prevent the parts from being poured out of the storage buckets. The design structure is as follows: one side plate 421 of the overturning bucket 42 is movably clamped in the strip-shaped slot 423 on the shovel bottom plate 422, and an adjusting cylinder 43 is also installed on the bottom surface of the shovel bottom plate 422, and the telescopic shaft of the adjusting cylinder 43 is connected to the At the bottom of the movable side plate 421 , the length of the strip-shaped slot 423 is greater than or equal to the telescopic stroke of the adjusting cylinder 43 .

When the lifting cylinder 30 is at the beginning of the stroke of the horizontal conveying mechanism 2, it is assumed that the lifting cylinder 30 is in an extended state and the overturning hopper mechanism 4 is at the lowest position. Next, the walking power 24 is activated to drive the entire reversing mechanism 3 and the overturning hopper mechanism. 4. Moving along the horizontal guide rail 20, when moving to the middle position of the horizontal guide rail 20, the lifting cylinder 30 shrinks, driving the reversing mechanism 3 and the overturning hopper mechanism 4 to rise, and the rotating cylinder 31 rotates 180° for reversing, making the dustpan shovel The shovel port of the bucket-shaped overturning bucket 42 is reversed (at this time, the overturning cylinder 40 and the adjusting cylinder 43 do not perform work), and the traveling power 24 continues to drive the reversing mechanism 3 and the overturning hopper mechanism 4 to move along the other end of the horizontal guide rail 30 after the reversal. . When moving to the key position or the fixed position of the storage box, the overturning cylinder 40 expands and contracts to do work, so that the overturning bucket 42 tilts and pours out the parts inside into the storage box. When the horizontal width of the bucket mouth of the turning bucket 42 needs to be adjusted, the adjusting cylinder 43 also expands and contracts to narrow or widen the bucket mouth of the turning bucket 42 .
