Abstract
A vibration absorption type steering wheel mechanism of plant protection equipment mainly comprises a steering swing arm frame, a connecting pin shaft, a fixing pin, a steering wheel support, a steering shaft, a locking bolt, a buffering spring, a vibration absorber, a limiting steel wire rope, a lining and a connecting pin. The steering swing arm frame is mounted onto the steering wheel support through the connecting pin shaft, the fixing pin, the buffering spring, the vibration absorber, the limiting steel wire rope and the connecting pin, the steering wheel support is provided with a vertical hole, the steering shaft is fixed in the vertical hole of the steering wheel support through the lining and a force transmission key, the steering wheel support can rotate leftwards and rightwards horizontally relative to a framework, the steering wheel support and the steering swing arm frame are provided with horizontal holes, and the steering swing arm frame can rotate up and down perpendicularly through the connecting pin shaft relative to the steering wheel support. The vibration absorption type steering wheel mechanism overcomes shortages of buffering structures of automobile plate springs and cross pin swing arms, and the steering swing arm frame and the steering wheel support are concealed in a rim of the wheel. In addition, the vibration absorption type steering wheel mechanism is compact in structure and convenient in use and maintenance, and avoids using sliding pairs.
Description
Technical field
The utility model belongs to the equipment for plant protection field, relates to a kind of equipment for plant protection damping type wheel flutter mechanism.
Background technology
At present, domestic and international self-propelled equipment for plant protection wheel flutter band damper mechanism mainly contain three kinds, a kind of is whole steeraxle with two former spring vibration dampings, similar steering axle of automobile; Another kind is a band rocking pin in the middle of the steeraxle, both sides dress rubber spring, similar engine air valve device; Also having a kind of is steering shaft and column suit cylindrical spring, similar motor bike steering front wheel.Such mechanism's radical function is can cushion to satisfy the impact that equipment for plant protection adaptation uneven road surface brings,, though the preceding reliable and practical ground Clearance of but limiting complete machine of two kinds of structures; Though the back is a kind of simple in structure, spring diameter is required also bigger along with load increases, influence between-wheel spacing, and wheel slides on guide rail during its buffering, makes its wearing and tearing increase.
The utility model content
The purpose of this utility model is to provide a kind of relatively simple for structure, easy to use and reliable, installation site rational equipment for plant protection damping type wheel flutter mechanism.
The technical solution of the utility model is: equipment for plant protection damping type wheel flutter mechanism mainly comprises: turn to the swing arm frame, connect bearing pin, set pin, wheel flutter support, steering shaft, lock(ing) bolt, recoil spring, shock absorber, spacing steel rope, lining, connecting pin; To turn to the swing arm frame to be installed on the wheel flutter support by connection bearing pin, set pin, recoil spring, shock absorber, spacing steel rope, connecting pin, the wheel flutter support is provided with vertical hole, steering shaft is fixed in the vertical hole of wheel flutter support by lining, force transfer key, and the relative frame of wheel flutter support turns left and right in can be in the horizontal direction; Wheel flutter support and turn to swing arm to set up to be equipped with lateral aperture turns to the swing arm frame can rotate down in vertical direction by the connection bearing pin relative to the wheel flutter support.
The described swing arm frame that turns to is provided with the stepped appearance pivot shaft.
Steering shaft links together by force transfer key, lining, bearing, oil sealing, lock(ing) bolt, frame and wheel flutter support.
Described shock absorber is installed in the recoil spring.
The utility model adopts the good effect that produces after the technique scheme to be: overcome the shortcoming with leaf springs of car and lateral pin swing arm buffer structure, turn to swing arm frame and wheel flutter support to be built in the rim for automobile wheel, compact conformation, do not limit ground Clearance and between-wheel spacing, be more suitable for crack, highland vehicle operation, and use easy to maintenancely, avoided the use sliding pair.
