Description
Technical field
The invention belongs to agricultural machinery technological field, more particularly to a kind of harvester for peanut.
Background technology
Peanut cultivation is the most universal in Asia, and harvesting work of the peanut after maturation is more heavy, the most frequently used at present
Means be that rural migrant worker works by hand, workload is big, and low efficiency of crop is a current major issue；With agricultural machinery
Fast development, the agricultural machinery of in the market also gradually increase, and harvester for peanut is the new equipment occurred in recent years, people
Start to gradually adopt harvester for peanut to carry out large batch of harvesting peanut, but the harvester for peanut occurred in the market due to
Design unreasonable, technology is immature, causes that the equipment volume produced is larger, complicated, cost is higher and efficiency of crop
It is low；And existing harvester for peanut mostly uses land wheel, during harvester for peanut is advanced, land wheel, which easily sink, to be caused
Perching knife can not normal harvest；For existing harvester for peanut in operation, the conveying of peanut seedling and peanut easily causes congestion, receives
The peanut obtained often adheres to substantial amounts of soil, to follow-up collection and plucks fruit and makes troubles, adds the work of aftercrop
Intensity.
The content of the invention
The present invention is in order to solve weak point of the prior art, there is provided a kind of compact-sized, reliable operation, advance it is steady
The harvester for peanut that the conveying of fixed, peanut seedling and peanut is smooth, simple operation, operating efficiency are high.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of harvester for peanut, including frame, machine

Connection.
Above-mentioned technical proposal is used, the invention has the advantages that：
1st, the present invention is provided with walking roller in bottom of the frame, the cylindrical structure of roller of walking, during the present invention advances, keeps away
Exempt from complete machine to sink in soft soil, cause perching knife can not normal harvest, while can be to being enclosed with the big soil of peanut on the ground
Block is rolled so that peanut and soil separation, is easy to pick up harvest.
2nd, sphenocephaly is provided with perching knife of the invention, perching knife can enter underground by sphenocephaly, by the peanut of underground
Shovel out, the setting of sphenocephaly significantly reduces the resistance suffered by perching knife, so as to add the service life of perching knife, shovels simultaneously
Knife is in splayed structure, and when perching knife scoops up peanut, peanut seedling and peanut are played the role of into a gathering to perching knife middle part,
Peanut seedling is avoided to be run out of from both sides, and the seedling separating roller that perching knife both sides are set plays the role of a guiding to peanut seedling, is easy to defeated
Device is sent to convey peanut seedling.
3rd, each sphenocephaly is fixedly connected on perching knife by dormant bolt respectively, each to shake seedling bar respectively by countersunk head spiral shell
Silk, which is fixedly connected on, leads on seedling roller, for ease of maintenaince changes.
4th, the hitch frame that frame front end is set can be connected with tractor, the clutch end of tractor and the power of gearbox
Input is connected, and gearbox imparts power to seedling separating roller and conveying device by transmission mechanism respectively, by support
Hydraulic cylinder adjustment depthkeeping roller height, the harvest depth of perching knife is determined by the height of depthkeeping roller.
5th, during tractor drives traveling forward of the invention, perching knife digs out the peanut of underground simultaneously together with peanut seedling
Conveying is promoted backward, and peanut seedling and peanut convey from the front to the back through conveying device, and peanut seedling and peanut are by leading seedling roller
When, on seedling roller is led shake seedling bar in the presence of, be delivered to below pressure roller, in the presence of pressure roller, by what is adhered on peanut seedling
Soil block crushes, and the soil block of crushing falls from the gap between cross bar, and the peanut seedling after pressure roller acts on, which is delivered to, to be located behind
Lead seedling roller, on seedling roller is led shake seedling bar in the presence of, peanut seedling and peanut, which are shaken seedling bar and dialed to, leads seedling double-edged fine-toothed comb, leads seedling
Double-edged fine-toothed comb falls the peanut seedling on seedling double-edged fine-toothed comb is led and peanut follows and leads seedling double-edged fine-toothed comb and shake up and down together by vibrating motor up-down vibration
It is dynamic, so as to further the soil being adhered on peanut be shaken off, and under drop down onto tail sheet, the gathering through tail sheet is by peanut seedling and flower
Fruit is put on the ground, completes harvest operation.
