Abstract
The utility model relates to an acicular air suction type precision seeding device which is a working part for agricultural machinery, comprising a frame (1), a support base (3), a seed box (5), a seeding drum (9), a suction needle (7), a drum axle (8) and a separation board (10). The utility model is used in field precision seeding and plug seedling operations. The utility model provides the advantages of simple structure, well distributed seedling pulling, small damage to seeds, low rate of empty seed, good operation quality, high production efficiency, convenient operation and reliable working etc. Therefore, the utility model provides a wide prospect of application and popularization.
Description
The utility model is a kind of workpiece of agricultural machinery, is used for field precise sowing and the point disk seedling growing operation of paddy rice, vegetables and other crops.
Field precise sowing of paddy rice, vegetables and other crops and point disk seedling growing operation, the seeding apparatus that uses mainly adopts mechanical type or other forms of air-sucking type at present, seeding accuracy also is not very satisfactory, particularly accurate live and point disk seedling growing operation for the field of paddy rice bud kind, damage to paddy rice bud kind is serious, influence the development of Rice Production, be badly in need of a kind of field precise sowing of paddy rice, vegetables and other crops and precision seed metering device of point disk seedling growing operation of can be used in the production.。
At the problem that above-mentioned prior art exists, the purpose of this utility model is that a kind of production efficiency height of design, operation quality are good, the field precise sowing that can be used for paddy rice, vegetables and other crops and the needle-like air-sucking type precision seed metering device of point disk seedling growing operation.
The utility model is made up of frame (1), bearing (3), seed-box (5), seeding cylinder (9), suction spindle (7), drum shaft (8), dividing plate (10).Seeding cylinder (9) is supported on the frame (1) by bearing (2) by drum shaft (8), suction spindle (7) is installed on the seeding cylinder (9), communicate by the inner chamber of pin hole with seeding cylinder (9), seed-box (5) is installed in the side top of seeding cylinder (9), in the front of seed-box (5) seed retaining plate (6) is installed, in the bottom of seed-box (5) seeds protecting plate (4) is installed, seeds protecting plate (4) go up and the seeding cylinder on suction spindle (7) corresponding position, position have the suction spindle groove, suction spindle (7) enters into seed-box (5) by the suction spindle groove, to be suction spindle (7) with respect to the motion of seed-box (5) enter from the bottom of seed-box (5) seeding cylinder (9), leave from top, seeding cylinder (9) is contained on the drum shaft (8) by bearing holder (housing, cover), can rotate with respect to drum shaft (8), drum shaft (8) is fixed on the bearing (2) by location-plate (13) and positioning seat (12), drum shaft (8) is two sections quill shafts, communicates with the induction chamber (17) and the air blowing chamber (18) of seeding cylinder (9) respectively.The induction chamber (17) of seeding cylinder (9) and air blowing chamber (18) are separated by dividing plate (10) and sealing strip (11).
Described embodiment is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structure diagram of the present utility model.
Accompanying drawing 2 is the right view of structure diagram of the present utility model.
The needle-like air-sucking type precision seed metering device that the utility model is related, can with the supporting use of multiple seeding machinery, be used for field precise sowing and the point disk seedling growing operation of paddy rice, vegetables and other crops.Needle-like air-sucking type precision seed metering device is made up of frame (1), bearing (3), seed-box (5), seeding cylinder (9), suction spindle (7), drum shaft (8), dividing plate (10).In seeding cylinder (9)) circumference on be evenly equipped with 16 suction spindles (7), seeding cylinder (9) is contained on the drum shaft (8) by bearing holder (housing, cover), can rotate with respect to drum shaft (8), drum shaft (8) is fixed on the bearing (2) by location-plate (13) and positioning seat (12), drum shaft (8) is two sections quill shafts, communicates with the induction chamber (17) and the air blowing chamber (18) of seeding cylinder (9) respectively.The induction chamber (17) of seeding cylinder (9) and air blowing chamber (18) are separated by dividing plate (10) and sealing strip (11), seed-box (5) is installed in the side top of seeding cylinder (9), in the front of seed-box (5) seed retaining plate (6) is installed, in the bottom of seed-box (5) seeds protecting plate (4) is installed, seeds protecting plate (4) go up and the seeding cylinder on suction spindle (7) corresponding position, position have the suction spindle groove, suction spindle (7) enters into seed-box (5) by the suction spindle groove, during work, seeding cylinder (9) is driven by driving wheel (15), drive suction spindle (7) enters from the bottom of seed-box (5), under the suction function of induction chamber (17), seed is adsorbed on the head of suction spindle (7), leave from the top of seeds protecting plate (4) then, when suction spindle (7) turns to the position of air blowing chamber (18) with seed with seeding cylinder (9), seed falls from suction spindle, finishes the seeding operation.Enter because suction spindle is the bottom from seed-box, discharge from top, therefore little to the damage of seed, and the probability of inhaling kind is big, and the seeding hole rate is low.
The utility model compared with prior art, this machine can be realized paddy rice, vegetables and other farming The field precise sowing of thing and hole plate seedling growth precise operation have simple in structurely, pull up seedlings evenly, Little to the seed damage, the seeding hole rate is low, and operation quality is good, and the production efficiency height is easy to operate, The advantages such as reliable operation. Application has a extensive future.
