Description
Technical field
The invention belongs to agricultural mechanical equipment field, be specifically related to a kind of protective device preventing grain header from bumping against with ridge in traveling process.
Background technology
Along with the development of agricultural mechanized processes, the application of China's grain header is also constantly popularized.Current widely used small harvester is generally made up of grain lifter, cutter, transmission device etc.Sprocket-type grain lifter is simple due to structure, is often adopted by more small harvester.It holds up standing grain system primarily of holding up standing grain support, chain and holding up standing grain pawl to form, and is installed on the front end of grain header.When harvesting, operating personnel are in the running of the rear control operation system of grain header, and crops are successively by being gathered in after grain lifter, cutter, transmission device.Because rear sight line is poor, operating personnel hold up standing grain system easily collide with ridge when operating grain header, grain header operate portions contacts ridge, thus damage grain header.How to prevent the barrier such as grain header and ridge from colliding, the main experience relying on operating personnel, does not also have good solution at present.
Summary of the invention
The present invention aims to provide a kind of grain header protective device, and grain header protective device of the present invention before the operate portions of grain header touches ridge, can cut off the power source of grain header operate portions, and protection grain header safety, overcomes the defect that prior art exists.
Technical scheme of the present invention is: a kind of grain header protective device, comprises probe, push rod, swing arm; Described probe is connected with one end of push rod, and the other end of described push rod and one end of swing arm are movably hinged, and the other end of described swing arm is located at by engage a gear bar; When engage a gear bar is positioned at drive shift, swing arm contacts with engage a gear bar; When described probe contacts is subject to thrust to barrier, promote swing arm by push rod, and then drive engage a gear bar to recover neutral position.
Described probe is connected with push rod by buffer gear, is installed on grain header foremost.
Described buffer gear is preferably spring mechanism, comprises spring, spring shaft, axle sleeve; Described spring housing on spring shaft, one end of spring and probe contacts, the other end contacts with axle sleeve; Described axle sleeve is enclosed within spring shaft, is installed on the front end of seedling supporting bracket of harvester.
Described swing arm preferably in L-shaped, is installed on gear frame by arm shaft at the flex point place of centre.
The structure of described gear frame is preferably: comprise a lever position, neutral gear bar position, two lever positions, reverse lever position; A described lever position, two lever positions are positioned at the homonymy of gear frame, and reverse lever position is positioned at the opposite side of gear frame, and neutral gear bar position is positioned at the centre of gear frame.
The organization establishes of described probe and push rod is more than two, and the push rod of each group is by yoke plate and swing arm interlock.
The invention has the beneficial effects as follows:
A kind of grain header protective device of the present invention comprises probe, push rod, swing arm; before grain header front end bumps against the barriers such as ridge; described probe first can touch the barriers such as ridge; by the effect of push rod and swing arm, the gear of grain header is resetted to get back to neutral gear by drive shift by the collide impact that produces of itself and ridge; before the operate portions of grain header touches ridge; cut off the power source that grain header advances; thus prevent the operate portions of grain header and the collision of ridge, avoid the damage of grain header operate portions.
Described probe is connected with push rod by buffer gear, is installed on grain header foremost.When probe encounters barrier, the operate portions of grain header has spring as buffering, reduces the active force that grain header operate portions receives, better protects grain header parts.
The present invention adopts mechanical device, without the need to the electronic control component of complexity, just can realize good defencive function by simple Design of Mechanical Structure; structure is simple, safe and reliable, can be applied to the grain header of various model; can adapt to more severe operating mode, and Financial cost is lower.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
Embodiment 1
Shown in Fig. 1, described grain header protective device comprises probe 1, push rod 5, swing arm 8; Described probe 1 is connected with one end of push rod 5, and the other end of described push rod 5 and one end of swing arm 8 are movably hinged, and the other end of described swing arm 8 is located at engage a gear bar 10 side; Described swing arm 8, in L-shaped, is installed on gear frame 7 at the flex point place of centre by arm shaft 9; When engage a gear bar 10 is positioned at drive shift, swing arm 8 contacts with engage a gear bar 10; When described probe 1 touch barrier be subject to thrust time, promote swing arm 8 with arm shaft 9 for the center of circle is rotated by push rod 5, and then promote its engage a gear bar 10 contacted and be back to neutral position.
When probe 1 collides ridge, receive the reaction force of ridge, promote push rod 5 and move backward, thus drive swing arm 8 to promote engage a gear bar 10 and get back to neutral gear from drive shift, cut off grain header power, make it to halt, avoid grain header to knock damage that ridge causes parts.
