a hole seeder

Abstract

The invention provides a hole-sowing planter. The hole-sowing planter comprises a base frame and a reciprocating sowing unit arranged at the front end of the base frame. The reciprocating sowing unit comprises a sowing plate and a drive wheel set. The drive wheel set comprises a driving wheel set and a rear wheel disk connected with the driving wheel set. The driving wheel set is connected to the base frame through a bearing, the rear wheel disk is connected with the sowing plate, and the sowing plate is connected to the base frame. By the adoption of the hole-sowing planter, seeds can be better protected, and weeding and harvesting operations at the later period are felicitated; on the premise that planting accuracy is improved and field layout tends to be reasonable, labor intensity is relieved, and working efficiency can be improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a hole sowing seeder. Background technique [0002] The hole sowing method is currently one of the most widely used sowing methods for sowing agricultural products such as peanuts, corn, beans, etc. As one of my country's important economic crops and oil crops, peanuts currently have a planting area of ​​5 million hectares and an annual output of 16.2 million tons. Due to the wide distribution of peanut planting areas, and the influence of climatic conditions, geographical conditions, and planting habits, the current planting models are diversified. Compared with the diversified planting models, the existing planting machinery is single, applicable and reliable. needs to be improved urgently. Specifically: [0003] Present sowing machinery drives the sowing wheel to rotate through the transmission form of chain transmission, and peanuts are brought into the sowing tube fo...

Problems solved by technology

During the sowing process of this kind of rotary planting machine, due to the rotation of the entire sowing wheel, the sowing wheel directly rubs against the base of the seed bin, and the large friction force causes a large thrust during the sowing process; at the same time, under the premise that the diameter of the sowing wheel itself is large, In addition to the height of the base of the seed bin, the height of the seed bin is higher, which leads to a higher center of gravity of the planting machine when it is filled with peanuts, resulting in laborious and easy-to-dump hidden dangers and deficiencies during the sowing process.

[0004] In addition, the sowing wheel loaded with peanuts usually sweeps away excess peanuts through simple methods such as brushes. The angle between the brush and the sowing wheel will affect the sweeping effect. Specifically: the theory of perpendicular to the circular surface of the sowing wheel along the diameter direction If the angle is too small, the rotation resistance of the seeding wheel will be large; if the angle is too large, the cleaning effect will be unsatisfactory
