Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1: the embodiment discloses a pneumatic transmission distribution type side deep fertilizing device: including frame 1 and connect in frame 1's fan 2, fertile case 3, feed sprayer 4 and furrow opener 7, fertile case 3 passes through fertilizer apparatus 31 and connects in the feed end of feed sprayer, and the air-inlet end of feed sprayer 4 is connected to the air-out end of fan 2 for with fertilizer drive to the discharge end of feed sprayer 4, the discharge end of feed sprayer 4 passes through distributor 5 and connects and lead fertile pipe 6, furrow opener 7 sets up in the place ahead of leading fertile pipe 6.
Specifically, the fertilizer distributor 31 is provided with a fertilizer motor 32 for driving the fertilizer distributor 31 to work and an adjusting hand wheel 33 for adjusting the working length of the fertilizer shaft.
As shown in fig. 2: the distributor 5 includes a fertilizer inlet pipe 51 and a plurality of fertilizer outlet pipes 52, the fertilizer inlet pipe 51 is connected to the discharge end of the feed injector 4 via a bellows 41, and the fertilizer outlet pipes 52 are connected to the fertilizer guide pipe 6. Considering that the fertilizer is subjected to the dual effects of wind force and gravity, in order to keep the fertilizer output of all the fertilizer tubes 52 uniform, the fertilizer inlet tubes 51 of the present embodiment are preferably vertically arranged, and all the fertilizer tubes 52 are symmetrically arranged with the center of the fertilizer inlet tube 51 as an axis, and since the fertilizer inlet tubes 51 are vertically arranged, the fertilizer is uniformly distributed in the fertilizer inlet tubes 51, so that when the fertilizer enters the distributor 5 from the fertilizer inlet tubes 51, and since the fertilizer tubes 52 are symmetrically arranged with the center of the fertilizer inlet tube 51 as an axis, the fertilizer can relatively uniformly enter the fertilizer guide tubes 6, and uniform distribution of the fertilizer among all the fertilizer guide tubes 6 is realized. The fertilizer discharging pipe 52 is further provided with a pipeline switch 53, whether the corresponding fertilizer guiding pipe 6 works or not can be controlled through the pipeline switch 53, for example, when the right side is needed to be supplied with fertilizer, the pipeline switch 53 corresponding to the left fertilizer discharging pipe 52 can be selected to be closed, fertilizer particles are prevented from being sent out from the left fertilizer guiding pipe 6, and the effect of supplying fertilizer by a single side is achieved.
The use of bellows 41 also has the following benefits: the bellows 41 inwards has the equidistance arch that distributes, and these archs collide with ascending fertilizer, make the fertilizer of upward motion constantly strike the resilience, promote the dispersion effect of fertilizer, are favorable to promoting the homogeneity of fertilization.
After the fertilizer enters the field, soil needs to be backfilled, so that a soil covering scraper 8 is arranged behind the fertilizer guide pipe 6. The earthing scraper 8 can be connected to the furrow opener 7 through the scraper support 81, and in practical application, the relative positions of the backfilling scraper 8 and the furrow opener 7 with the frame can be adjusted.
As shown in fig. 3: the air-out end of fan 2 and feed sprayer 4 collineation, such benefit is exactly to avoid the wind channel to bend and cause the resistance to the air current, moreover, is favorable to fertilizer along advancing fertile pipe 51 evenly distributed, alleviates collision, the adhesion of fertilizer and pipeline. On the other hand, the discharge port of the fertilizer discharger 31 is inclined towards the direction of the air outlet end of the fan 2, which is referred to as an angle a in fig. 3, that is, a in fig. 3 is an acute angle, so that the fertilizer can have an initial velocity of forward movement when entering the feed injector 4, which is beneficial to acceleration of the fertilizer by the airflow, and moreover, the fertilizer is prevented from being blown back to the fertilizer discharger 31 by the airflow due to the acute angle between the fertilizer and the feed injector.
In operation, the frame 1 is mounted on a planting machine, such as a rice transplanter, and under the traction of an agricultural machine, the furrow opener 7 moves forward to form a fertilizing ditch for fertilizing in the field. On the other hand, under the drive of the fertilizer discharging motor 32, the fertilizer enters the feeding injector 4 through the fertilizer discharging device 31, under the action of the high-pressure airflow generated by the fan 2, the fertilizer is driven to move forwards, enters the fertilizer guide pipe 6 through the hose 41 and the distributor 5 in sequence, is discharged into the fertilizing ditch, and then soil on two sides of the fertilizing ditch is backfilled into the fertilizing ditch under the action of the soil covering scraper 8.
Compared with the prior art, the fertilizer distributor adopts the pneumatic distribution conveying system to realize multi-row fertilizer distribution, and has the advantages of good fertilizer distribution uniformity and continuity and good consistency of discharge capacity of each row. Since the fertilizer is driven by the air flow to enter the fertilizer guide pipe 6 through the distributor 5, the fertilizer is uniformly fed into the field, and the amount of fertilizer can be adjusted by the fertilizer distributor 31. The fertilizer inlet pipes are vertically arranged, and the fertilizer outlet pipes 52 are symmetrically arranged by taking the center of the fertilizer inlet pipe 51 as an axis, so that fertilizer can relatively uniformly enter the fertilizer guide pipes 6, uniform distribution of the fertilizer among all the fertilizer guide pipes 6 is realized, and uniform distribution of the fertilizer in all the fertilizing ditches is realized.
The invention adopts an electric control synchronous fertilizer discharging amount control system, and the principle is as shown in figure 4:
during fertilizing operation, setting a target fertilizing amount through a potentiometer, collecting the speed of a real-time machine and the rotating speed of a fertilizing shaft by combining an encoder arranged on a speed measuring wheel, and calculating a target rotating speed of fertilizing; meanwhile, an encoder arranged on the fertilizer discharging shaft detects the rotating speed of the fertilizer discharging shaft in real time; the decision system takes the target discharge capacity, the machine tool speed and the fertilizer discharging rotating speed as input quantities of the control system to obtain the rotating speed control quantity of the current fertilizer discharging device, then the controller outputs corresponding PWM waves through a PID speed regulating algorithm, and after amplification and conditioning are carried out, the fertilizer discharging motor is driven to regulate the fertilizer discharging rotating speed on line, so that synchronous fertilizer discharging operation is realized.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
