Abstract
The utility model discloses a small -size manpower seeder, including frame, walking wheel, supporting wheel, sowing mechanism and drive mechanism, wherein drive mechanism is chain drive drive sprocket and driven sprocket, it is epaxial that the travelling wheel wheel is expert at in drive sprocket installation, and driven sprocket installs at the seeding wheel epaxially, and it is equipped with a gear change case to be expert at between travelling wheel and the sowing mechanism, be driven sprocket on the input shaft of gear change case to take turns epaxial drive sprocket through the chain with the walking wheel and link to each other, be drive sprocket on the output shaft of gear change case, and it is continuous with the epaxial driven sprocket of seeding wheel through the chain, form two -stage chain drive, the utility model discloses a sow the function that the interval can be adjusted in real time, widened the application range of seeder, improved production efficiency greatly.
Description
Technical field:
This utility model relates to a kind of technical field of agricultural machinery, especially a kind of small manual seeder.
Background technology:
In rural area, particularly mountainous rural area, plough not in flakes, large-scale agricultural machinery is put to good use not open, peasants before adopts farm cattle to draw pears, the mode of artificial seeding, time-consuming, take a lot of work, effort, for this situation, small manual seeder arises at the historic moment, and deeply by the welcome of vast farmers, existing small manual seeder includes frame, road wheel, support wheel, sowing mechanism and drive mechanism, wherein drive mechanism many employings Chain conveyer, drive sprocket is arranged on road wheel wheel shaft, driven sprocket is arranged on sowing wheel shaft, in use through constantly improving and perfect, substantially can meet the requirement of peasant's sowing.By observation for many years and understanding, although existing small manual seeder is welcome by peasant, but the probability used is not high, know that existing small manual seeder in use exists a crucial problem through inquiry, the mainly adjustment of seed spacing, it is known that, the seed spacing of various crops is different, if adjusting seed spacing, existing small manual seeder can only be taked to change sprocket wheel, or change the size of drive sprocket, or change the size of driven sprocket, thus to mate several sprocket wheel not of uniform size, not only increase cost, also make troubles to user.
Utility model content:
nullThis utility model is for the deficiencies in the prior art，A kind of small manual seeder is provided，This is novel is not only simple in structure，Seed spacing can be adjusted easily，Technical problem to be solved in the utility model is that drive mechanism is improved，The rotating speed of sprocket wheel is sowed at the situation down conversion that need not change sprocket wheel，Realize the adjustment of seed spacing，The technical scheme is that this utility model of this utility model includes frame、Road wheel、Support wheel、Sowing mechanism and drive mechanism，Characterized by further comprising a speed-changing gear box，This speed-changing gear box is placed in frame，And between road wheel and sowing mechanism，The power shaft of speed-changing gear box is paid road wheel wheel shaft by transmission and is connected，The output shaft of speed-changing gear box is paid sowing wheel shaft by transmission and is connected，Requirement according to crop seeding spacing，Speed-changing gear box arranges several transmission range.
Above-mentioned transmission is paid as gear drive；
Above-mentioned transmission is paid as Chain conveyer；
Above-mentioned transmission is paid as belt transmission；
Above-mentioned transmission is repaid can adopt transmission shaft driven；
Said gear change speed gear box arranges 2～6 transmission range.
Mechanism of the present utility model is as follows: the first requirement according to crop seeding spacing, speed-changing gear box is adjusted suitable gear, promotion seeder is walked, the power of road wheel drives seeding wheel to rotate enforcement sowing through two-stage Chain conveyer, as adjusted seed spacing, only gear need to be converted by the operation handle of change speed gear box.
Compared with prior art, this utility model is not only simple in structure rationally, easy for operation, particularly achieves the function that seed spacing can adjust in real time, it may be achieved the sowing of various crop, has widened the use scope of seeder, has substantially increased production efficiency.
Accompanying drawing illustrates:
Accompanying drawing is this utility model structural representation.
Detailed description of the invention:
This utility model includes frame 4, road wheel 1, support wheel 8, sowing mechanism 7 and drive mechanism, wherein drive mechanism is Chain conveyer, including drive sprocket 2, 11 and driven sprocket 12, 9, also include a speed-changing gear box 5, this speed-changing gear box is placed in frame, and between road wheel and sowing mechanism, it the power shaft of speed-changing gear box is driven sprocket 12, and be connected with drive sprocket 2 on road wheel wheel shaft by chain 3, it the output shaft of speed-changing gear box is drive sprocket 11, and be connected with the driven sprocket 9 on sowing wheel shaft by chain 10, form two-stage Chain conveyer, speed-changing gear box is designed as the speed change of 2～6 grades, handle 6 can be passed through implement to control.Chain conveyer part of the present utility model can also be converted to belt transmission or gear drive or transmission shaft driven, no matter adopting which kind of transmission, as long as the rotating speed of seeding wheel can be realized controlling and adjusting.
Claims (5)
1. a small manual seeder, including frame, road wheel, support wheel, sowing mechanism and drive mechanism, characterized by further comprising a speed-changing gear box, this speed-changing gear box is placed in frame, and between road wheel and sowing mechanism, the power shaft of speed-changing gear box is paid road wheel wheel shaft by transmission and is connected, and the output shaft of speed-changing gear box is paid sowing wheel shaft by transmission and is connected.
