Description
Technical field
The utility model relates to combine field of mechanical technique, particularly relates to a kind of screw feeder cylindrical shell locking device of grain header.
Background technology
The screw feeder cylindrical shell of existing grain header, especially unloading screw conveyor cylindrical shell, unloading operation must be carried out after tanker fills grain, need to release (falling down) unloading cylindrical shell during unloading operation and carry out unloading, the action of falling down of unloading cylindrical shell is generally controlled by the flexible of hydraulic jack, but in work or transportation, due to hydraulic system fault or part is aging causes, the improper releasing of grain barrel-removing, grains unloading system may be damaged in working order or knock surrounding barrier, may result in an automobile accident in by Automobile Transportation process.
China Patent No. is separately had to be CN203251670U, the day for announcing is 2013.10.30, disclose a kind of combine tanker screw feeder cylinder self-locking device, comprise the shank of the key seat be located on tanker and the bayonet lock being located at screw feeder cylinder, described shank of the key seat is hinged with shank of the key by rotating shaft, the bayonet lock when position of shank of the key is fixed with screw feeder cylinder is corresponding, and shank of the key is provided with the bayonet socket of corresponding bayonet lock in rotating shaft side, and shank of the key is provided with the spring be connected with tanker at rotating shaft opposite side.By improving self-locking device, realizing combine tanker after unloading, can screw feeder cylinder be securely fixed on tanker; And during tanker unloading, screw feeder cylinder can be made again to throw off like a cork, easy to operate.Above-mentioned patent screw feeder cylinder sticks into by angle when regaining, but when releasing, needs people that buckle is pulled open and just can release, and can be able to collide with grain storage box when screw feeder cylinder is regained, and causes screw feeder cylinder or/and grain storage box distortion.
Utility model content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of locking device of screw feeder cylindrical shell of grain header, this locking device passes through bump rubber at unloading screw conveyor cylinder when regaining, and prevents rigid collision, extends the service life of screw feeder cylindrical shell.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of screw feeder cylindrical shell locking device of grain header, comprise grain storage box and unloading screw conveyor cylinder, unloading screw conveyor cylinder is hinged on grain storage box, it is characterized in that: also comprise holder, bump rubber, snap close seat board and spring, described holder is located on grain storage box, described bump rubber is located on holder, and described holder is provided with lock pin; Described snap close seat board is located on unloading screw conveyor cylinder, and described snap close seat board is hinged with snap close, and described spring one end is connected with snap close, and the other end is connected with snap close seat board, and when unloading screw conveyor cylinder is regained, snap close engages with lock pin.
Also comprise hydraulic jack, described hydraulic jack one end is connected with grain storage box, and the other end is connected with unloading screw conveyor cylinder.
The utility model has the following advantages:
1, the utility model by arranging holder, bayonet lock and bump rubber on grain storage box, unloading screw conveyor cylinder arranges snap close seat board, this snap close seat board is hinged with snap close, and snap close and snap close seat board are provided with spring, the bump rubber that the holder of grain storage box is arranged, rigid collision when effective alleviation unloading screw conveyor cylinder is regained, and release part impinges power, snap close on unloading screw conveyor cylinder engages with lock pin under the action of the spring, and prevent it from coming off, during unloading, also easily snap close and lock pin are thrown off, and extend the service life of screw feeder cylindrical shell simultaneously.
2, the utility model also comprises hydraulic jack, and described hydraulic jack one end is connected with grain storage box, and the other end is connected with unloading screw conveyor cylinder.The withdrawal of unloading screw conveyor cylinder is all passed through the propelling movement of hydraulic jack with releasing or shrinks driving spring, makes snap close throw off with lock pin or engage, alleviates labour intensity.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of screw feeder cylindrical shell locking device of grain header, comprise grain storage box 1 and unloading screw conveyor cylinder 2, unloading screw conveyor cylinder 2 is hinged on grain storage box 1, to realize relatively rotating, also comprise holder 4, bump rubber 3, snap close seat board 7 and spring 6, described holder 4 is located on grain storage box 1, described bump rubber 3 is located on holder 4, bump rubber 3 is positioned at the position (when unloading screw conveyor cylinder 2 reclaims) contacted with unloading screw conveyor cylinder 2, described holder 4 is provided with lock pin 8, described lock pin 8 is the hook (as shown in Figure 4) of one " U " type, described snap close seat board 7 is located on unloading screw conveyor cylinder 2, described snap close seat board 7 is hinged with snap close 5(generally hinged by rotating shaft), described spring 6 one end is connected with snap close 5, and the other end is connected with snap close seat board 7, when unloading screw conveyor cylinder 2 is regained, snap close 5 engages with the hook of lock pin 8.
Further, also comprise hydraulic jack 9 in the utility model, described hydraulic jack 9 one end is connected with grain storage box 1, and the other end is connected with unloading screw conveyor cylinder 2.The withdrawal of unloading screw conveyor cylinder 2 is all passed through the propelling movement of hydraulic jack 9 with releasing or shrinks driving spring, makes snap close 5 throw off with lock pin 8 or engage.
During unloading, unloading screw conveyor cylinder 2 is released, and makes every effort to overcome by hydraulic jack 9 pulling force taking spring 6, and snap close 5 is rotated, crosses neutral position, snap close 5 is pulled to open state by spring 6, unloading.As shown in Figure 1 and Figure 2.
When unloading screw conveyor cylinder 2 is regained, the power of hydraulic jack 9 makes snap close 5 rotate, and cross neutral position, snap close 5 is pulled to locking states by spring 6, regains.As shown in Figure 3
It should be noted that: the power that spring 6 provides can lock unloading screw conveyor cylinder 2, but hydraulic jack 9 thrust can not be exceeded.
