Small-sized manual seeder

Abstract

A small-sized manual seeder comprises a frame, a traveling wheel, a supporting wheel, a seeding mechanism and a transmission mechanism, wherein the transmission mechanism is chain transmission and comprises a driving chain wheel and a driven chain wheel, the driving chain wheel is mounted on an axle of the traveling wheel, the driven chain wheel is mounted on an axle of a seeding wheel, a gear boxis arranged between the traveling wheel and the seeding mechanism, the driven chain wheel is arranged on an input shaft of the gear box, the driven chain wheel is connected with the driving chain wheel on the axle of the traveling wheel through a chain, the driving chain wheel is arranged on an output shaft of the gear box, and the driving chain wheel is connected with the driven chain wheel on the axle of the seeding wheel through a chain to form two-stage chain transmission. The small-sized manual seeder realizes a function that sowing pitch can be adjusted in real time, widens use range ofa seeder, and greatly improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a small manpower seeder. Background technique [0002] In rural areas, especially in mountainous areas, the arable land is not contiguous, and large-scale agricultural machinery cannot be used. In the past, farmers mostly used the method of plowing cattle and pears and manual sowing, which was time-consuming, labor-intensive and labor-intensive. In view of this situation, small-scale manual sowing The machine came into being and was welcomed by the majority of farmers. The existing small manpower planter includes a frame, a walking wheel, a support wheel, a seeding mechanism and a transmission mechanism. On the wheel shaft, the driven sprocket is installed on the sowing wheel shaft. After continuous improvement and perfection during use, it can basically meet the requirements of farmers for sowing. Through years of observation and understanding, although the exist...

Problems solved by technology

Through years of observation and understanding, although the existing small human planters are popular with farmers, the probability of using them is not high. After inquiry, we know that there is a key problem in the use of the existing small human planters, mainly the sowing distance As we all know, the sowing spacing of various crops is different. If you want to adjust the sowing spacing, the existing small manpower seeder can only replace the sprocket, or change the size of the driving sprocket, or replace the driven sprocket. In this way, it is necessary to match several sprockets of different sizes, which not only increases the cost, but also brings inconvenience to users.
