Description

Seed sowing machine

Technical Field

The invention belongs to the technical field of agricultural equipment, and particularly relates to a seed sowing machine.

Background

The seeder is a planting machine taking crop seeds as seeding objects, is used for the seeder of a certain type or a certain type of crops, is usually named by crop species, such as a grain drill, a corn hill planter, a cotton seeder, a pasture grass broadcaster and the like, and in the first 1 century of the public, China popularizes and uses an animal-drawn seed plough, which is the earliest drill in the world, is still applied in dry-farming areas in the north nowadays, in order to ensure consistent row spacing when the seeder is used for seeding, a row marker is required to be installed on the seeder, and some seeders are also provided with a seed metering monitoring device, so that seeding progress is automatically monitored and a signal is sent when a fault occurs, so that the seeding progress is timely eliminated.

In present farming, a large amount of mechanical equipment have appeared and have replaced traditional manual planting mode, all kinds of seed seeders have appeared in the seed seeding, current seed seeder needs seed size and the depth of planting according to the difference, change the size of seeder and drilling equipment's size, often because the hole diameter demand of seed seeding is big and lead to the size of seeder also need synchronous grow, lead to the seeder volume too bulky, action and operation produce inconveniently.

Disclosure of Invention

The invention provides a seed sowing machine which can avoid the situation that seeds are sowed on the ground due to too small holes and reduce the volume of a drilling device in order to overcome the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: a seed sowing machine comprises a barrel, a driving device sleeved on the barrel, a discharging device arranged on the barrel, a first driving piece arranged on the barrel, a first telescopic rod arranged on the first driving piece, a drilling device arranged on the first telescopic rod, and a protection device arranged on the drilling device; the drilling device comprises a second driving piece, a rotating shaft and an orifice plate, wherein the rotating shaft is rotatably arranged on the second driving piece, and the orifice plate is matched with the rotating shaft.

According to the invention, through the arrangement of the hole expanding plate, when the rotating shaft drills soil, the hole expanding plate is driven to rotate along with the rotating shaft through the matching of the rotating shaft and the hole expanding plate, so that the diameter of a hole which can be drilled by the rotating shaft is increased, the situation that the size of the hole for sowing seeds is too small is ensured not to occur, and the situation that the seeds are sowed on the ground due to too small holes is avoided; through the setting of hole enlargement board, enlarge drilling equipment's workable drilling diameter, reduced drilling equipment's volume itself for the seeder need not to change the size of this equipment because the size of seed changes, has improved the suitability, has avoided because the hole diameter demand of seed seeding is big and the size that leads to the seeder also needs synchronous grow, and then avoids because the action and the operation that the seeder volume leads to excessively are huge and produces inconvenient circumstances.
