Description
The utility model provides a kind of self dumping lorory back door jack recloser.
Known self dumping lorory back door jack recloser, door operator behind the example 2515 type agriculture trucks, as shown in Figure 2, be made of front arm (27), pull bar (28), spring (29), guide plate bearing (30), rear arm (31), rear arm bearing (32), roller (33), guide plate parts such as (34), forward and backward rocking arm (27), (31) all are connected on the tipping bucket (26) by bearing.When tipping bucket (26) is elected rising, spring (29) affects pull bar (28) right lateral, pull bar (28) drives rear arm (31), roller (33) right lateral, promote front arm (27) left-hand revolution and open the back door, when tipping bucket (26) descended, compressing roller (33) was gone up left lateral at guide plate (34), and rear arm (31) drives also left lateral of pull bar (28) during with roller (33) left lateral, pull bar (28) drives the rotation of front arm (27) anticlockwise direction, shuts the back door.This mechanism's weak point is that member is many, and not enough or when losing efficacy no pulling force, pull bar (3) is difficult to right lateral when spring (4) pulling force, it is unreliable to work.
The purpose of this utility model is to overcome above-mentioned weak point, and provides a kind of simple in structure, the self dumping lorory back door jack recloser of reliable operation.
The purpose of this utility model is achieved in that the four-bar mechanism that is made of the self dumping lorory back door jack recloser pull bar, rocking arm, vehicle frame, tipping bucket, and the length of each bar of four-bar mechanism is: the length of bar one is L
1, sell the distance of selling behind the pull bar before being pull bar, the length of bar two is L
2, being the distance of selling rocker arm pin behind the pull bar, the length of bar three is L
3, being the distance of tipping bucket rest pin to rocker arm pin, the length of bar four is L
4, be the distance of selling the tipping bucket rest pin before the pull bar, L

2, driving link is bar three (tipping bucket), frame is bar four (vehicle frame).
The pull bar front end connects with pin before the pull bar with draw-bar seat on being fixed on vehicle frame, and back end of tie rod and rocking arm are sold after with pull bar and be connected, and rocking arm connects with rocker arm pin with rocker arm bracket on being fixed on tipping bucket.
With the tipping bucket rest pin vehicle frame rear support that is fixed on the tipping bucket rear support on the tipping bucket and be fixed on the vehicle frame is connected.
Pull bar, rocking arm are rigid member, and pull bar is a rod, and rocking arm is " L " shape.
When tipping bucket rises or descend, since the effect of four-bar mechanism, the automatic switch back door.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the front view of self dumping lorory back door jack recloser.
Fig. 2 is a door operator front view behind the 2515 type agricultural vehicles.
In conjunction with the accompanying drawings 1, embodiment of the present utility model is further described.The self dumping lorory back door jack recloser constitutes four-bar mechanism by pull bar (6), rocking arm (10), vehicle frame (25), tipping bucket (17), and the length of each bar of four-bar mechanism is: the length of bar one is L
1, being the distance of the pin (11) behind the pull bar of pin (3) before the pull bar, the length of bar two is L
2, being that pin (11) is to distance of rocker arm pin (9) behind the pull bar, the length of bar three is L
3, being the distance of tipping bucket rest pin (4) to rocker arm pin (9), bar four length are L
4, be the preceding pin of pull bar (3) distance, L to tipping bucket rest pin (4)

2=30mm, L
3=150mm, L
4=80mm.Pull bar (6), rocking arm (10) are rigid body, and pull bar (6) is a rod, and rocking arm (10) is " L " shape, and hook is long to be 50mm.The driving link of four-bar mechanism is that bar three is tipping bucket (17), and frame is that bar four is vehicle frame (25).Pull bar (6) front end connects with pin (3) before the pull bar with draw-bar seat (2) on being fixed on vehicle frame (25), pull bar (6) rear end and rocking arm (10) connect with pin (11) behind the pull bar, rocking arm (10) be fixed on tipping bucket under the rocker arm bracket (8) of Beam (7) connect with rocker arm pin (9).Tipping bucket rest pin (4) connects the tipping bucket rear support (5) that is fixed on the tipping bucket (17) with vehicle frame rear support (2) on being fixed on vehicle frame (25).Back door (13) connects with back door bearing (14) by back door bolt (15), and back door bearing (14) is fixed on the otic placode (16) of tipping bucket (17), and back door lock (15) is 70mm to the vertical distance of otic placode (16), is 100mm to the horizontal throw of rear end.Bearing (18) connects with lifting support (20) by preceding pin (19) before the tipping bucket, and lifting support (20) middle part connects with plunger (22) by middle pin (21), and the bottom connects with connecting rod (24) by back pin (23).Elected by plunger (22) when tipping bucket (17) and to rise to from the horizontal by 20 ° of angle lappings when oblique, because the effect of four-bar mechanism, pull bar (6) affects the hook of rocking arm (10) to leave the following Beam (12) at back door (13), back door (13) is around back door bolt (15) left-hand revolution, open at the back door, beginning self-unloading goods; Plunger (22) continues to rise, and continues self-unloading; After self-unloading finishes, tipping bucket (17) begins to descend, when tipping bucket (17) during from the horizontal by 5 ° of angles, the back door resets, same because the effect of four-bar mechanism, pull bar (6) affects rocking arm (10), and the hook of rocking arm (10) props up the following Beam (12) at back door (13), bars up the back door.
The utility model has the advantage of: utilize vehicle frame, tipping bucket as the member of four-bar mechanism, so only need make pull bar and rocking arm. This apparatus structure is simple, and is easy to manufacture, with low cost; Reliable operation.
