A kind of harvester of Sandbur fruit
Technical field
The utility model relates to a kind of gathering unit of Sandbur fruit in bioecology experiment.
Background technology
Sandbur belongs to grass family, is instruction plant, by seminal propagation, tillering ability and reproductive ability extremely strong.Sandbur is bred rapidly after intrusion home environment, fights for resource, and suppress other plant to grow with other plant, makes the decline of other crop qualities, output reduction, destroys the ecological balance.At present for this invasive species of Sandbur, generally select weeds chemical control, but adopt chemical control Sandbur cost high, easy secondary pollution; Adopt the mode Be very effective manually pulled out, but working strength is large, efficiency is low.
About in the research experiment of Sandbur, be insoluble problem to the collection of Sandbur fruit always.Sandbur is when maturation, and fruit surface can form tapering hard thorn, except the fruit that manual method gathers Sandbur, not better, method more easily.
Summary of the invention
The technical scheme that the problem that the utility model is the collection of solution current Sandbur fruit adopts is: the utility model devises a kind of harvester being applicable to the small-sized Sandbur fruit in laboratory, by being accompanied with the cylinder of threshing tooth, main shaft, crank, screen cloth, fan and case etc. form, cylinder (5) and crank (8) are fixed on main shaft (6), screen cloth (7) is positioned at below cylinder, and fan (12) is fixed between advancing air grid (14) and rear air intake grid lattice (11).Can make drum rotating by shake crank, thus produce centrifugal force, Sandbur fruit is come off from stem, and the Sandbur fruit split away off will focus on the space of this bottom of device by screen cloth.
The object of the fan designed by the utility model, mainly solves in above-mentioned fruit screening process, the removing problem of the foreign material such as Sandbur cauline leaf relic.In the front end of this device, electric fan is housed, inner blower can blows in this device, the foreign material produced are blowed to the exhaust outlet of this device afterbody and discharge in fruit screening process, to improve the quality that Sandbur fruit gathers.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment
In the schematic appearance of the present utility model shown in Fig. 1, there is by Sandbur plant one end of fruit to stretch into device from feeding hopper (15), push down the other end of plant with left hand; The right hand holds crank (8), clockwise direction shakes, make cylinder (5) fast rotational, the projection of the upper irregular arrangement of cylinder (5) is threshing tooth (3), and the fruit on Sandbur can be hit down by threshing tooth (3) in along with cylinder (5) rotary course; The fruit split away off can be fallen on the screen cloth (7) of cylinder (5) below, screen cloth (7) leaves wide about 1 centimetre, be about the grid of 5 centimetres, for screening Sandbur fruit, the fruit filtered out can be concentrated in the space bottom auto levelizer.
In the partial sectional view of the present utility model shown in Fig. 2, the fan (12) that two diameters are 8 centimetres is equipped with in the front end of described device, fan electromotor (13) is fixed between advancing air grid (14) and rear air intake grid lattice (11), fan passes through driven by power, the wind produced directly blows to the front bottom end of screen cloth (7), wind direction is relative with cylinder (5) direction of rotation, effectively the foreign material mixed in Sandbur fruit can be blowed to the exhaust outlet (1) of this device afterbody; When provided with fan motor (13), the switch that tape speed regulates can be chosen, regulate fan wind-force to facilitate.
Outside case of the present utility model is made up of left coaming plate (16), right coaming plate (9), squab panel (4), upper encloser (2), left coaming plate (16), right coaming plate (9), upper encloser (2) and pedestal (10) are adopted and are screwed, squab panel (4) adopts folding to be hinged mutually with pedestal (10), after the threshing of above-mentioned Sandbur fruit, screening process terminate, squab panel (4) can be opened, to take out the Sandbur fruit screened.
