Abstract
The utility model relates to technical field of agricultural mechanical equipment; especially a kind of covering unit of drill; including the subsequent earthing wheel being symmetrical set of dispenser is arranged in; earthing wheel is connect by shaft with the bracket being fixed on seeder; shaft is connected by the power source of transmission device and seeder; earthing wheel includes multiple blade uniformly distributed along shaft circumference direction, and the direction of rotation of blade is consistent with the direction that soil collapses backfill, and the soil that ditching device is separated backfills.The utility model is smashed using the soil that the blade that rotation is beaten separates ditching device, not having good hardened piece of big soil block after smashing soil by whipping, the soil is porous, it is covered on good permeability on seed, be conducive to the watering and fertilising of next step, emergence rate can be greatly improved, there is preferable promotional value.
Description
Technical field
The utility model belongs to technical field of agricultural mechanical equipment, and in particular to a kind of covering unit of drill.
Background technique
Bunch planting type seeder is the planting machinery of sowing seed cavitation by a line spacing and hill spacing.Every cave can broadcast 1
Or several seeds, claim single grain fine sowing or more bunch plantings respectively, is mainly used for the intertillage such as corn, cotton, beet, sunflower, beans
Crop, also known as row-crop drill.The entire operation such as the achievable trench digging of each seeder monomer, seeding, earthing, suppression
Journey.
Wherein it is mostly important be also on emergence influence maximum link be exactly ditch, seeding and earthing, traditional seeder is such as
Patent No. CN201621393845.2 discloses " a kind of hand propelled corn trench digging earthing seeder ", and flotation device is exactly left
The soil that ditching device assigns to both sides is collapsed go back to centre, seed is covered by right two scraper plates, and this is simplest earthing dress
Set, but there is also certain defect, for example, be possible in the separated soil of ditching device bulk soil block and hardened piece, if directly
It takes back and fills out and will be pressed in above seed, influence to emerge.
Utility model content
The purpose of this utility model is to provide a kind of covering unit of drill, it is intended to solve covering device in the prior art
The problem of soil block of bulk and hardened piece of backfill are influenced into emergence.
To achieve the above object, a kind of covering unit of drill of the utility model is adopted the following technical scheme that including setting
It sets in the subsequent earthing wheel being symmetrical set of dispenser, earthing wheel is connected by shaft with the bracket being fixed on seeder
It connects, shaft is connected by the power source of transmission device and seeder, and earthing wheel includes multiple leaf uniformly distributed along shaft circumference direction
The direction of rotation of piece, blade is consistent with the direction that soil collapses backfill, and the soil that ditching device is separated backfills.
The bracket is adjustable height bracket, to adjust height of the earthing wheel relative to ground.
The bracket includes the upper bracket connecting with seeder and covers outside upper bracket, can be slided up and down relative to upper bracket
And the lower bracket locked, lower bracket lower end is connect with shaft.
The upper bracket upper end can be axially rotatablely connected vertically with seeder, to adjust the rotation angle of earthing wheel.
The direction of rotation of the earthing wheel is that direction rotates inwards and backwards, and the angle between two earthing wheels is 90 ° to 160 °.
The blade is divided into two groups, and the blade tip of every group of 4-8 blade, blade is bent towards the direction of another set blade.
The blade tip tilt angle of the blade is 120 ° to 160 °.
The transmission device is chain conveyer.
The beneficial effects of the utility model are: the soil that the utility model is separated ditching device using the blade that rotation is beaten
Earth is smashed, and not having good hardened piece of big soil block after smashing soil by whipping, the soil is porous, is covered on good permeability on seed,
The watering and fertilising for being conducive to next step, can greatly improve emergence rate, have preferable promotional value.
Detailed description of the invention
Fig. 1 is the main view of the utility model left side earthing wheel；
Fig. 2 is the top view of the utility model.
Appended drawing reference: 1- earthing wheel, 2- shaft, 3- bracket, 301- upper bracket, 302- lower bracket, 4- transmission device, 5- leaf
Piece.
Specific embodiment
The embodiment of utility model is described further with reference to the accompanying drawing.
A kind of embodiment of covering unit of drill of the utility model, as Fig. 1 is the utility model left side earthing wheel
Main view, Fig. 2 are shown in the top view of two earthing wheels, including the subsequent earthing being symmetrical set of dispenser is arranged in
Wheel 1, the direction of rotation of earthing wheel 1 are that direction rotates inwards and backwards, and the angle between two earthing wheels 1 is 90 °, and earthing wheel 1 passes through
Shaft 2 is connect with the bracket 3 being fixed on seeder, and shaft 2 is connect by transmission device 4 with the power source of seeder, is driven
Device 4 is preferably chain conveyer, drives earthing wheel 1 to rotate by power source drive shaft 2, and earthing wheel 1 includes multiple along shaft
The direction of rotation of the uniformly distributed blade 5 of circumferencial direction, blade 5 is consistent with the direction that soil collapses backfill, and ditching device is separated
Soil backfill.
In order to adjust height of the earthing wheel 1 relative to ground, bracket 3 includes the upper bracket 301 connecting with seeder and set
Outside upper bracket 301, the lower bracket 302 that can be slided up and down and lock relative to upper bracket 301,302 lower end of lower bracket and shaft 2
Connection.
In order to adjust the rotation angle of earthing wheel 1,302 upper end of upper bracket can be axially rotatablely connected vertically with seeder.
In order to improve the effect of breaing up of earthing wheel 1, it is two groups that blade 5, which is divided to, every group of 4 blades, and the blade tip of blade 5 is towards separately
The direction of outer one group of blade 5 is bent, and blade tip tilt angle is 130 °.
In other embodiments, transmission device 4 can also be using V belt translation, gear driving etc..
In other embodiments, blade 5 divides for three groups, four groups, reduces the axial spacing of blade, and the density for improving blade is come
Blade is set to beat the more broken of soil, more carefully.
Specific embodiment is the further explanation to the utility model rather than limits, and is come to those of ordinary skill in the art
It says and further transformation is done to structure in the case where not departing from the utility model in essence content, and all these transformation all should belong to
The protection scope of the appended claims for the utility model.
