Description

The suction specision dibbler

The utility model belongs to the improvement of mulch film spreading and seeding machine dibbler, particularly the suction specision dibbler.

The sower kind of using both at home and abroad is more at present, the sowing variety of components of corresponding employing is also more, the seeding apparatus that a kind of pneumatic seeder is wherein arranged is to utilize that the negative-pressure air-flow essence of negative-pressure air fan is measured kind, seeding, and the seed that is discharged from drops in the kind ditch that plough leaves.This seeding parts can essence be measured kind, seeding, injuring-free seed, but it is a little high to charge seed, and the accuracy of the location of charging seed is poor.Seeding unit has the complicated special-purpose variable transmission mechanism of a cover, its complex structure, and weight is big, and the cost height uses and adjusts inconvenience, and it is bigger that seeding unit work is influenced by unit operation speed.This seeding unit is limit by structure, only adapts to carry out single-seed drilling or adopt and after planting spread the film operation earlier under the open country condition, treat that seedling grows after, again with artificial liberation seedling.Artificial seedling setting not only labour intensity is big, and needs the labour who drops into also more in a short time.

The purpose of this utility model is to provide a kind of suction specision dibbler, and it is simple in structure, and reliable operation is easy to use, seeding parts transmission mechanism-free, the bunch planting of can punching on film can realize that zero elevation charges seed, zero velocity is charged seed, and kind of the point that falls is accurate, and the seeding parts are not limited by unit operation speed.

The utility model is achieved in that a kind of suction specision dibbler, have the left hand plate of wheel hub and circular right side dish and constitute the rolling element that a side center offers cylinder open by endless belt, rolling element is installed on the dibbler axle, and can rotate around the axis, the uniform slot that offers on the periphery at endless belt middle part, welding fixedly indenting tool of long trough respectively at each slot place, articulated movable indenting tool on the fixing square plate of the notch of fixing indenting tool bottom, in the rolling element cylinder open, by bearing the suction disk that has the circular arc air drain is installed on the wheel hub of left hand plate, suction disk be provided with the negative pressure air flue, the seed chamber of seed inlet and seeding slideway is fixed together, the negative pressure air flue of seed chamber is communicated with the air drain of suction disk, the seed plate that is evenly equipped with feed outlet on the card circumference is being installed between suction disk and the seed chamber, seed plate and left hand plate relative fixed link together, and rotate with left hand plate.

The side plate of hitch frame is installed at the two ends of dibbler axle, and during work, hitch frame traction dibbler axle rolls rolling element and advances on the face of kind of bed, and seed chamber and suction disk do not rotate.The negative-pressure air-flow of being introduced by appendix enters in the air drain of seed chamber by the negative pressure air flue above the seed chamber, negative pressure gas in the air drain is by feed outlet absorbed seed uniform on the seed plate, when seed plate turns to below the horizontal level of dibbler dead ahead corresponding position synchronously with left hand plate, the discontinuities of the circular arc negative pressure air drain on the aspiration dish is died the suction hole on the seed plate that forwards the relevant position to, the effect that seed loses negative-pressure air-flow comes off automatically, and enter along slot corresponding on the seeding slideway of seed chamber and the endless belt in the fixedly indenting tool and movable indenting tool of corresponding one-tenth closure state, finish essence and measure kind and divide and plant.Hinged movable indenting tool along with the rotation of dibbler and fixedly indenting tool often be in to open and constantly change with closed, from under along clockwise direction 210 degree in the position ranges fixedly indenting tool and the head of movable indenting tool be in the unlatching situation, wherein do not have seed yet.When fixedly indenting tool and movable indenting tool continued to turn to the following 30-35 degree of dead ahead horizontal level position along clockwise direction with dibbler, the seed that seed plate is discharged fell in the fixedly indenting tool and movable indenting tool that is in closed condition, is in situation to be broadcast.When fixedly indenting tool that is in closed condition and movable indenting tool are comprising seed and continue with dibbler under forward to clockwise to contact with kind of a bed mulch film, mulch film is punctured a square opening, penetrate simultaneously in the soil of kind of bed to certain degree of depth (promptly sowing desired depth), this moment is under the pressure effect of dibbler deadweight, compressing activity indenting tool rotates around jointed shaft, make movable indenting tool become the unlatching situation with movable indenting tool, and the soil that will plant bed is left hole, a cave, seed falls into the hole, cave simultaneously, realize the bunch planting of punching on the film, zero elevation is charged seed, and zero velocity is charged seed.When dibbler continues to rotate along clockwise direction, be in the fixedly indenting tool and the also companion rotation of movable indenting tool of unlatching situation, and break away from kind of the hole, cave of bed, carry out next working cycles.Because seeding parts transmission mechanism-free of the present utility model, it is simple in structure, and reliable operation is easy to use.The bunch planting of can punching on film has realized that zero elevation charges seed, needs speed to charge seed, and kind of the point that falls is accurate, and the seeding parts are not limited by unit operation speed.The utility model has been realized automatic rupture of membranes bunch planting, has changed elder generation and has after planting spread the film operation, treat that seedling grows after, carry out the conventional art of artificial rupture of membrane liberation seedling again, alleviated labour intensity significantly, saved a large amount of labours.
