Description
Technical field
The utility model particularly belongs to agricultural use, and in particular to a kind of fertilising pipette tips.
Background technology
It is essential link during breed of crop, the existing mode to Crops in Applying Fertilizer to Crops in Applying Fertilizer
Two kinds of predominantly manual fertilising and mechanical fertilization, and China's most area is applied by hand still using the craft fertilising more fallen behind
Fertile mode operates time-consuming laborious, and the waste of fertilizer is big, and a small number of plains regions is deposited using the device of mechanical fertilization
In complicated, many defects such as manufacturing cost height.
Now mostly on the market is to be applied fertilizer to crops using fertilization gun, but current fertilising pipette tips are to agriculture
After the completion of crop fertilization, weeping is serious when lifting pipette tips, causes the loss in vain of fertilizer, while inserting in pipette tips
When entering into soil, soil is easy to block the spray-hole in pipette tips, causes fertilizer outflow unsmooth.
Utility model content
The purpose of this utility model is that in view of the above shortcomings of the prior art, providing a kind of fertilising pipette tips, the pipette tips
It is simple in structure, the weeping of pipette tips can be effectively prevented, meanwhile, when fertilising, fertilizer outflow is more smooth.
What the technical solution of the utility model was realized in：A kind of fertilising pipette tips, including hollow pipette tips ontology, institute
It is taper to state pipette tips body bottom portion, is provided with an annular groove on the pipette tips ontology, the pipette tips ontology opens up in annular groove
Have several spray-holes, one be also associated in the pipette tips ontology and unloads fertile disk, it is described unload to offer in fertile disk unload fertile hole, the rifle
Head inner body wall is additionally provided with internal thread unloading above fertile disk, and is threaded with connecting cylinder, the connection by the thread segment
Cylinder is outer to be provided with external screw thread, and integrally formed with a cylinder in the connecting cylinder, fluid inlet, the stream are offered in the cylinder
Body entrance includes the large diameter hole of the diameter holes and lower section of top, and the large diameter hole is connected with fertile hole is unloaded, the large diameter hole it is straight
Diameter is more than the diameter for unloading fertile hole, is provided with compressed spring in the large diameter hole, spherical plug, institute are connected in the compressed spring
The diameter for stating spherical plug is more than diameter holes.
Further, the spray-hole is four, and uniformly ring-type is arranged in annular groove.
Further, the diameter holes bottom margin offers chamfering.
Further, the pipette tips ontology includes main part and conical head, and the conical head is threaded on main part.
Compared with prior art, the utility model has the beneficial effects that：1, by the way that an annular groove is arranged on pipette tips ontology,
It is inserted into soil by pipette tips, spray-hole is not easy to be blocked；
2, the pipette tips are simple in structure, by the way that compressed spring and spherical plug is arranged, can effectively prevent the water clock of pipette tips
Phenomenon；
3, the pipette tips can be by dismantling conical head, to achieve the effect that quickly clean pipette tips when cleaning.

Specific implementation mode
A kind of fertilising pipette tips shown in Fig. 3, including hollow pipette tips ontology 1,1 bottom of pipette tips ontology are arrived refering to fig. 1
Portion is taper, and an annular groove 2 is provided on the pipette tips ontology 1, and the pipette tips ontology 1 offers several in annular groove 2
Spray-hole 9 is also associated with one in the pipette tips ontology 1 and unloads fertile disk 3, it is described unload to offer in fertile disk 3 unload fertile hole 4, the pipette tips
1 inner wall of ontology is additionally provided with internal thread unloading above fertile disk 3, and is threaded with connecting cylinder 12, the company by the thread segment
It is provided with external screw thread outside connect cylinder 12, integrally formed with a cylinder in the connecting cylinder 12, fluid inlet is offered in the cylinder,
The fluid inlet includes the large diameter hole 6 of the diameter holes 5 and lower section of top, and the large diameter hole 6 is connected with fertile hole 4 is unloaded, described
The diameter of large diameter hole 6 is more than the diameter for unloading fertile hole 4, is provided with compressed spring 7 in the large diameter hole 6, connects in the compressed spring 7
It is connected to spherical plug 8, the diameter of the spherical shape plug 8 is more than diameter holes 5.12 spiral shell of the utility model pipette tips ontology 1 and connecting cylinder
Line connects, and facilitates the connection of compressed spring 7 and spherical plug 8.
Process is as follows when in use for the utility model, this is connected to fertilization gun by the external screw thread outside connecting cylinder 12
On, when being applied fertilizer, among pipette tips are inserted into soil, due to being provided with annular groove 2 on pipette tips ontology 1, and spray
Hole 9 is provided in looping pit, so when pipette tips are inserted into, often has certain space, soil between soil and spray-hole 9
Earth will not block up spray-hole 9, and fertilizer can smoothly be flowed out from spray-hole 9, in addition, the utility model can effectively prevent fertilizer
Material water clock from pipette tips, particularly, when fertilizer is sent to fertilization gun by delivery pump from fertilizer tank, fertilizer flows in fertilizer rifle
When moving in pipette tips, under the pressure of fertilizer, spherical plug 8 is rushed to open, then fertilizer from diameter holes 5, large diameter hole 6 and
It unloads and is flowed out in fertile hole 4, and spray fertilizer through spray-hole 9, after soil application is completed at one, pause uses conveying
Pump, due to the effect of not no pressure, spherical plug 8 blocks diameter holes 5 under the action of compressed spring 7, and fertilizer just will not be from
It is flowed into pipette tips in fertilizer rifle, effectively avoids the water clock of fertilizer, prevent its loss.
Further, the spray-hole 9 is four, and uniformly ring-type is arranged in annular groove 2.Specifically, this practicality is new
The spray-hole 9 of type is set as four, and annular arrangement so that when fertilising, can more uniformly be applied among soil.
Further, 5 bottom margin of the diameter holes offers chamfering 11.Chamfering 11 is opened up in 5 bottom of diameter holes, is prevented
When spherical plug 8 abuts to diameter holes 5, it is excessive that 5 bottom margin of diameter holes bears pressure, keeps its service life less.
Further, the pipette tips ontology 1 includes main part and conical head 10, and the conical head 10 is threaded in main body
In portion.During pipette tips use, inevitably decline from spray-hole 9 into soil particle, in order to enable removing soil
It is more convenient when particle, so the pipette tips ontology 1 of the utility model includes main part and conical head 10, needing multiple gun
When head ontology 1 is cleared up, directly conical head 10 is backed out, you can easily clear soil particle.
Embodiment provided above is the better embodiment of the utility model, only is used for facilitating illustrating the utility model, and
It is non-to impose any limitation on the present invention, any those of ordinary skill in the art, if not departing from
In the range of the carried technical characteristic of the utility model, locally changes or repair using made by the utility model disclosed technology content
The equivalent embodiment of decorations, and without departing from the technical characteristics of the utility model content, still fall within the utility model technical characteristic
In the range of.
