Description
Technical field
The present invention relates to field of agricultural production technologies, and in particular to a kind of plant essence amount interval spot application system and side
Method.
Background technology
Corn is one of the staple food crop in China, and corn seeding fertilising is the important step of Maize Production again, is improved
Seeding quality and the reasonable fertilizer of administration are the important leverages that seedlings are uniform and strong.Major part corn drill in China's has been realized at present
Determine cave Precision Seeding, can fertilizer broadcast the mode of applying or traditional outer groove-wheel drilling.Corn fertilizing mode in addition to outer groove-wheel row replacement,
When intertilling top dressing, some colleges and universities of China and scientific research institutions have researched and developed fertilizing type, i.e., are carried out near plant root
Man-to-man fertilizer.Planted as shown in figure 1, a kind of singling of certain engineering college of colleges and universities research and development pricks cave top dressing device by defertilizing tube (1), corn
Strain position sensing mechanism (2), horizontal displacement compensation mechanism (3), cam stop piece (4), frame (5), the input of top dressing device power
Axle (6), fertilizer box (7), ratchet clutch (8), vertical hole pricking mechanism (9), batch (-type) fertilizer distributor (10), cavitation device (11)
Composition.When the plant position sensing mechanism (2) of any side detects plant, the ratchet clutch of the side
(8) engage, clutch shaft power is delivered to the horizontal displacement compensation mechanism (3) and vertical hole pricking mechanism (9) of the side, completes fixed point and hangs down
The straight process for pricking cave, cavitation device (11) and batch (-type) fertilizer distributor (10) cooperative motion therewith, completion fertilizer process.
Following defect be present in prior art：
First, for traditional outer groove-wheel bar broadcast mode, because corn plants are away from big, row application mode during corn seeding
Fertilizer with applying the blank between two plants of corns, the waste of fertilizer is caused, utilization rate of fertilizer is low.
Second, for the intertillage fertilizing type shown in Fig. 1, though have been carried out utilizing the singling top dressing of mechanical detection mechanism, can
No plant realizes that singling is applied fertilizer to base fertilizer when being sowing for detecting.

The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Fig. 2 shows the structural representation for the plant essence amount interval spot application system that one embodiment of the invention provides.Ginseng
See Fig. 2, the plant essence amount interval spot application system that the present embodiment provides, including：Moving device 100, fertilizer apparatus 200, broadcast
Kind device 300 and control device 400；The seeding apparatus 300 is connected with the fertilizer apparatus 200 by support, and in institute
State and advanced under the driving of moving device 100；Wherein, velocity sensor is installed on the moving device 100；
The seeding apparatus 300 includes：Plants case, feed mechanism for seed, discharge plate speed probe, grain conductor, sowing supervision device,
One plough and press wheel；Preferably, first plough is double disk opener；
Wherein, the plants case is connected with the feed mechanism for seed, and the feed mechanism for seed is connected with the grain conductor, and the discharge plate turns
Fast sensor is fixed on the feed mechanism for seed, and the sowing supervision device is fixed on the middle lower end of the grain conductor；
The fertilizer apparatus 200 includes：Fertilizer box, fertilizer guiding tube, automatically controlled fertilizer apparatus and the second plough；Preferably, described
Two ploughs are single-disc colter；
Wherein, the fertilizer box is connected with the fertilizer guiding tube, and the automatically controlled fertilizer apparatus is fixed on the middle lower end of the fertilizer guiding tube,
The automatically controlled fertilizer apparatus is used for big according to the opening time of default fixed point dose control fertilizer apparatus, opening time and opening
It is small；
The control device 400 is used for the gait of march of the moving device obtained according to the velocity sensor, the row
Automatically controlled row described in the discharge plate rotating speed and the planting time control of sowing supervision device monitoring that discharge plate speed probe obtains
The working condition of fertile device is to ensure the synchronization of plant seeding and fertilizing.
For example, in a kind of optional embodiment, the control device 400 be used for the discharge plate rotating speed be non-zero and
When the moving device is at the uniform velocity advanced, according to the related dress of the gait of march of the moving device, seeding apparatus and fertilizer apparatus
Put parameter and calculate time △ T since planting (being fallen seed) to opening fertilizer guiding tube, it is and current according to the sowing supervision device
The a certain planting time and the △ T that monitor determine the opening time of the automatically controlled fertilizer apparatus, while according to the sowing time
Interval determines the follow-up opening time interval of automatically controlled fertilizer apparatus, to ensure that seed manure is fallen with point；Wherein, fertilizer is led from planting to opening
The time △ T of pipe refer to ensure to fall fatbits it is synchronous with planting point on the premise of from seeds fall is monitored to opening fertilizer guiding tube
Shortest time.
Here, the relevant apparatus parameter of seeding apparatus and fertilizer apparatus refers to the physical size of seeding apparatus and fertilizer apparatus
And the parameter such as seeding, fertilizer performance.
Wherein, when calculating since planting (being fallen seed) to the time △ T for opening fertilizer guiding tube, first according to seeding apparatus
With the physical size of fertilizer apparatus and seeding, fertilizer performance calculate automatically controlled fertilizer apparatus open after switch fertilizer landing time t1 with
And seed lands time t2 since whereabouts to seed, spacing in the rows and the gait of march of moving device are then integrated again, is calculated
When ensuring to fall fatbits and planting point synchronization from seeds fall is monitored to the most short time △ T of fertilizer switch is opened, here,
When calculating time △ T, foundation is：The drop point distance of the planting point monitored and first time fertilizer is just the smallest positive integral of spacing in the rows
Times.
" a certain planting time for currently being monitored according to the sowing supervision device and described it is understood that above
△ T determine the opening time of the automatically controlled fertilizer apparatus, while the follow-up unlatching of automatically controlled fertilizer apparatus is determined according to sowing time interval
Time interval, to ensure that the same point of seed manure is fallen " refers to：In time △ T after having monitored seeds fall, automatically controlled fertilizer is opened
Device, fertilizer apparatus opening time or openings of sizes are determined according to dose, and adjacent two are calculated further according to spacing in the rows and gait of march
Strain plant seeding time interval t3, and the opening time interval using t3 as follow-up automatically controlled fertilizer apparatus.
