Abstract
The utility model discloses a semi-trailer with self-unloading device, which is used to match with the walking tractor. The carriage and the operator's seat are separable structures. The bottom of the carriage is connected with a spring steel sheet, a hinge structure, a wheel shaft, and a steering pole. The carriage of the trailer rotates around the hinge shaft to realize turnover unloading when unloading. The front end of the bottom of the carriage has a cam lock device, which can make the carriage be fixed at a horizontal position. A damping device is arranged between the carriage and the steering pole, which overcomes the impingement generated by the collision of the carriage and the earth surface.
Description
A kind of superimposed trailer that has self-unloading device can use with walking tractor matching, belongs to the farm machinery class.
In prior art, the technical characterstic that has the agricultural superimposed trailer of self-unloading device is: for hinge is connected, realize its locking with a catch gear between operator's saddle and railway carriage.When unloading, open latching device, execute a power that makes progress with manpower at the railway carriage front end, railway carriage is lifted and around angle of wheel, hand machine is also drawn certain altitude backward together with operator's saddle.This self-unloading device is manipulated inconvenience, and railway carriage rotates dumb, and it is too big to expend strength.
The utility model is for addressing the above problem the superimposed trailer that a kind of new band self-unloading device is provided.
Technical essential of the present utility model is that trailer railway carriage and operator's saddle are separable structure, steel spring is fixed on the bottom of trailer railway carriage, wheel shaft is connected with the traction girder, thereby linkage links together spring plate and wheel shaft and has realized that railway carriage is connected with the hinge of traction girder, and linkage is positioned at the centre portion of railway carriage longitudinal direction.Front end in the railway carriage bottom is being fixed cramp bar, and the lower end of cramp bar is connecting the chucking pin.The cam lock device is installed on the traction girder, and when the trailer railway carriage was in horizontality, the chucking pin inserted in the chucking mouth of cam lock device.Between hinge means bottom railway carriage and the cam lock device shock absorption device is arranged.The bottom of shock absorption device is fixed on the traction girder, shock absorption device comprises an elastic body, the urceolus of elastic body can rotate by the axle on base, and the outer external part of elastic body is connected with chain or rope, and the other end of chain or rope is connected on the support of railway carriage bottom.
When unloading, move the bar handle of cam lock holding mechanism, catch gear is unclamped, impose thrust upwards at the front end of railway carriage, railway carriage can overturn around hinge axis, realizes the upset unloading.After the unloading, the application of force makes railway carriage recovery level attitude, and the chucking pin inserts in the chucking mouth, and trailer is fixed.
Because the trailer railway carriage separates with operator's saddle, the upset of railway carriage does not influence operator's saddle and hand machine, thereby can realize unloading easily; Because linkage is at the centre portion of railway carriage, generally can keep the balance or the rear portion of railway carriage front and back slightly heavy after loading in the railway carriage substantially, when unloading, when unclamping catch gear, or utilize the moment that the rear portion slightly heavily produces and needn't apply manpower, or the thrust that imposes gently upwards at the railway carriage front end can make railway carriage upset unloading, thereby overcome the excessive defective of consumption power in the prior art; Because shock absorption device is arranged at railway carriage bottom, the impact that produces owing to railway carriage and ground-surface collision in the process of upset unloading can be overcome by spring device, thereby has reduced vibrations.
Fig. 1～Fig. 4 is the scheme drawing of the utility model embodiment
Fig. 1 is the superimposed trailer scheme drawing of band self-unloading device described in the utility model.Among the figure: (1) is the traction girder, front end is connected with hand machine, (1a) be the operator's saddle part, (2) be the cam lock device, its locking frame (2g) is fixed on the traction girder (1), (3) be railway carriage, (4) be shock absorption device, (5) are spring plate, and (6) are linkage, (7) be wheel shaft, (8) being wheel, (2M) is the catch gear bar handle, (2K) cramp bar of selling for chucking, the two supports of wheel shaft (7) wheel, and middle and traction girder (1) is fixed together.
Scheme drawing when Fig. 2 locks for the cam lock device
Scheme drawing when Fig. 3 unclamps for the cam lock device
The cam lock device comprise locking frame (2g), latch segment (2a) and (2e), spool (2b) and (2h), limit shaft (2c) and spring (2d).Locking frame (2g) is fixed in traction girder (1), and axle (2b) is bearing in that locking frame (2g) is gone up and keeps normal-running fit with hole on (2g).Latch segment (2a) is captiveed joint with axle (2b).Axle (2h) is bearing on the locking frame (2g), and latch segment (2e) keeps normal-running fit with axle (2h).Spring (2d) is connected latch segment (2a) with (2e).Limit shaft (2c) is fixed on the locking frame (2g), and position-limited trough on the latch segment (2a) and limit shaft (2c) are bearing fit.At locking state, chucking pin (2f) inserts the chucking mouth of catch gear, and trailer is fixed
When overturning unloading, unclamp this latching device.Turning handle (2M) drives spool (2b) and latch segment (2a) clockwise rotates, and locking face and (2e) disengaging are unclamped latching device, and spring (2d) drives latch segment (2e) and clockwise rotates, and the chucking mouth is made progress (as shown in Figure 3).Chucking is sold (2f) thereby can be deviate from the upset that can realize the trailer railway carriage from the chucking mouth.
Work as discharged, railway carriage is recovered in the process of level attitude, chucking pin (2f) downwards and the inclined-plane that is pressed into chucking mouthful (2e) rotated counterclockwise, when the chucking pin is supported in the qualification position, spring (2d) drives latch segment (2a) left-hand revolution, and camming surface is identical and realization locking with locking face (2e).After the locking, the upper end of the chucking mouth of latch segment (2e) will tighten pin (2f) and block, and it can not be deviate from, thereby railway carriage is stabilized in level attitude.
Fig. 4 is the shock absorption device scheme drawing.This device comprises base (4a), goes up end support (4b), elastic body (4c), chain or rope (4d).Base (4a) is fixed on the traction girder (1), last end support (4b) is fixed on the railway carriage bottom, the urceolus of elastic body (4c) can rotate by the axle on base (4a), and chain or rope (4d) connect the outer external part and the last end support (4b) of elastic body (4c).When upset was unloaded, the spring of elastic body overcame the impact owing to railway carriage and collision on the ground generation, thereby has played cushioning effect.
