A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 2 shows the structural schematic diagrams for the plant essence amount interval spot application system that one embodiment of the invention provides.Ginseng
See Fig. 2, plant essence amount interval spot application system provided in this embodiment, comprising: moving device 100, is broadcast fertilizer apparatus 200
Kind device 300 and control device 400；The seeding apparatus 300 is connected with the fertilizer apparatus 200 by bracket, and in institute
It states and advances 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 connect with the feed mechanism for seed, and the feed mechanism for seed is connect 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 connect 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 travel speed for the moving device that the control device 400 is used to be obtained according to the velocity sensor, the row
The planting time of seeding disk rotating speed and sowing supervision device monitoring that discharge plate speed probe obtains controls the automatically controlled row
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 seeding disk rotating speed be non-zero and
When the moving device is at the uniform velocity advanced, according to the related dress of the travel speed of the moving device, seeding apparatus and fertilizer apparatus
It sets parameter and calculates time △ T since planting (falling seed) to opening fertilizer guiding tube, and it is 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 subsequent opening time interval of automatically controlled fertilizer apparatus, to guarantee 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 under 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 parameters such as seeding, fertilizer performance.
Wherein, when calculating the time △ T since planting (falling seed) to 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 turn on the switch rear fertilizer landing time t1 with
And seed lands time t2 to seed since whereabouts, then integrates the travel speed of spacing in the rows and moving device again, calculates
Ensure to fall fatbits it is synchronous with planting point when switch shortest time △ T to fertilizer is opened from monitoring seeds fall, here,
When calculating time △ T, foundation are as follows: the drop point of the planting point and first time fertilizer that are monitored is apart from the smallest positive integral for being just 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 determines the opening time of the automatically controlled fertilizer apparatus, while the subsequent unlatching of automatically controlled fertilizer apparatus is determined according to sowing time interval
Time interval, to guarantee that the same point of seed manure is fallen " refers to: in time △ T after having monitored seeds fall, opening automatically controlled fertilizer
Device, determines fertilizer apparatus opening time or openings of sizes according to dose, calculates adjacent two further according to spacing in the rows and travel speed
Strain plant seeding time interval t3, and using t3 as the opening time interval of subsequent automatically controlled fertilizer apparatus.
In addition, the sowing supervision device cooperate automatically controlled fertilizer apparatus be also used to monitor seed manure it is synchronous as a result, and will monitor
Seed manure synchronized result be uploaded to control device so that seeding time for monitoring according to the sowing supervision device of control device is real
The opening time of automatically controlled fertilizer apparatus described in Shi Xiuzheng (referring herein to the derivation of △ T, according to the fertilizer time of automatically controlled fertilizer apparatus and is broadcast
The seeding time of kind monitoring can retrodict the synchronized result of chemical fertilizer drop point and seed drop point, finely tune the size of △ T, then according to real
When the seeding time, control the opening time of fertilizer apparatus.This corrects the stability for being mainly in view of feed mechanism for seed seeding, is especially easy
The ground wheel drive feed mechanism for seed of skidding).
In addition, in specific implementation, it can be with installing terminal equipment (such as mobile phone, palm PC on the moving device 100
Or display screen), parameter initialization module is provided on the terminal device, the parameter letter stored in the parameter initialization module
Breath include at least the travel speed information of moving device, discharge plate rotary speed information, seeding apparatus and fertilizer apparatus relevant apparatus
The spacing in the rows information of parameter information and plant to be applied fertilizer, the terminal device are used for the parameter that will be stored in parameter initialization module
Information is sent to the control device.
In another optional embodiment, the control device 400 be also used to the seeding disk rotating speed be non-zero and
When the moving device is non-at the uniform velocity traveling, controls the automatically controlled fertilizer apparatus and be in normally open, wherein the automatically controlled fertilizer apparatus
Refer to that control fertilizer apparatus persistently applies fertilizer in normally open.
For example, speed is changing always when in field, starting or tail of the earth stop when carrying out plant fertilising operation
(being at this time non-at the uniform velocity state), in order to guarantee plant not fertilizer deficiency, as long as having monitored, plant is sowed and vehicle does not stop,
Automatically controlled fertilizer apparatus is kept to be in open state.
In another optional embodiment, the control device 400 is also used in the seeding disk rotating speed be zero time control
The automatically controlled fertilizer apparatus is made to close.
It is understood that when the seeding disk rotating speed is zero, explanation has stopped sowing, then should close at this time automatically controlled
Fertilizer apparatus, to stop applying fertilizer.
