Abstract
The utility model provides a capacity variable cell and wheel type seeding apparatus, which belongs to a component of a seeding machine. The utility model has the structure that a seed containing cell is arranged on a seeding wheel (11) which is arranged in an outer housing (9), and a slide block (3) which is arranged on the bottom of the seed containing cell is connected with a guide rod (6); a roller (7) which is arranged on the lower part of the guide rod is contacted with a cam (8). The slide block of the utility model seeding apparatus follows the seeding wheel to rotate together and makes longitudinal motion simultaneously, and thus, changes of the capacity of the seed containing cell are realized. The utility model has the advantage that seeds do not break in the process of seeding, and has the advantages of favorable cavitation performance, simple structure and low cost.
Description
The utility model relates to the assembly on the agricultural machinery, especially the seeding unit on the sower.
At present, the seeding unit on the sower that is used for intertillage crop such as peanut, cotton, corn that uses on the agricultural is in the seeding process, though brush kind effect through seeds brushing device, brush away but only center of gravity can be positioned at the seed that holds kind more than the nest eye upper port plane, and center of gravity is positioned at and holds kind below the nest eye upper port plane, but wholely not exclusively holding kind of the seed of nest intraocular again, the airtight descending stage after brush is planted, or be sheared, or be extruded, or carried secretly, so that fragmentation takes place, and influence the cavitation performance.Though and air-suction seeding unit seed percentage of damage is low, complex structure, cost height.
The purpose of this utility model provides a kind of varying capacity nest eye Type Seed Metering Device, to avoid the seed fragmentation, improves the cavitation performance.
The utility model is to realize like this, varying capacity nest eye Type Seed Metering Device, kind of a case is arranged, there is seed wheel to be fixed on the feed shaft in the shell of kind case below, there is seeds brushing device the seed wheel top, portion has slide block and guide rod to be installed together on the appearance kind nest eyeground of described seed wheel, and spring is arranged on the guide rod, and the cam on there is roller the guide rod bottom and is fixed on shell contacts.
Adopt the varying capacity nest eye Type Seed Metering Device of said structure, compare with common mechanical formula seeding unit, seed does not have fragmentation, and the cavitation performance is good.Compare with air-suction seeding unit, simple in structure, cost is low, is easy to promote.
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and operation principle.
Fig. 1 is the schematic diagram of the utility model structure.
As shown in drawings, the varying capacity nest eye Type Seed Metering Device of the utility model, it has kind of a case (1), plant in the shell (9) of case below and have seed wheel (11) to be fixed on the feed shaft (10), there is seeds brushing device (2) the seed wheel top, it is characterized in that, have slide block (3) and guide rod (6) to be installed together in the appearance kind nest eyeground of described seed wheel (11) portion, spring (5) is arranged on the guide rod, the cam (8) on there is roller (7) the guide rod bottom and is fixed on shell (9) contacts.
Feed shaft rotates under the effect of external force (as land wheel), drives seed wheel and rotates, and the seed in the kind case enters appearance kind of a nest intraocular and fills kind.After filling kind, under the effect of seeds brushing device, keep apart with the seed of planting in the case, and center of gravity is positioned at the seed that holds kind more than the nest eye upper port plane brushes away holding kind of the seed of nest intraocular.Roller under the effect of spring all the time the outline along cam move.During negative area on moving to cam, hold kind of the slide block of nest eyeground portion with moving in the guide rod, hold kind of a nest eye and increase to enough big capacity, made originally and planted below the nest eye upper port plane because of center of gravity is positioned to hold, but the whole seed that is not exclusively brushed away holding kind of nest intraocular again falls into fully and holds kind of a nest intraocular.Seed wheel is rotated further, and roller continues to move along the outline of cam, and appearance kind of nest eye through airtight (being to be the zero clearance between seed wheel and the shell) the descending stage, arrives the seeding unit bottom with seed wheel.Under seed deadweight and action of cam (this moment, roller moved to the bossing of cam, and guide rod drives slide block and moves outward, and seed is pushed), seed falls, discharges, thereby finishes the seeding process.
Also have positioning key (4) on the guide rod, it is installed in the groove on the seed wheel, can guarantee that guide rod does not rotate, and the direction of roller is constant.
Can adapt to the requirement of different big seedlet seedings by the thickness that changes slide block.
Hold kind of the quantity of nest eye on the seed wheel, can set according to the requirement of crop spacing in the rows.
Claims (1)
1, varying capacity nest eye Type Seed Metering Device, it has kind of a case (1), plant in the shell (9) of case below and have seed wheel (11) to be fixed on the feed shaft (10), there is seeds brushing device (2) the seed wheel top, it is characterized in that, there are slide block (3) and guide rod (6) to be installed together in the appearance kind nest eyeground of described seed wheel (11) portion, spring (5) is arranged on the guide rod, and the cam (8) on there is roller (7) the guide rod bottom and is fixed on shell (9) contacts.
