Abstract

The utility model relates to an agricultural implement, in particular to a high-frequency fixed-point fertilizer deep applicator suitable for top application of crops such as corn and the like. The fertilizer distributor is also composed of a fertilizer box (1), a fertilizer discharging pipe (2), a switch (3), a pull wire (11), a swing rod (12) and the like, the pull wire (11) and the switch (3) are driven to move by the swing of the swing rod (12) to control fertilizer discharging, and the fertilizer distributor is hung on a plough (14) to perform fertilizer application operation, and is characterized in that: the upper section of the switch (3) is provided with a balancing weight (4). The counter weight block pulls the swing rod (3) to return under the action of gravity, so that the frequency is high, excessive impact on crops cannot be caused, the defects that the conventional spring return device is low in reciprocating frequency and cannot operate at high speed or the impact force is large and damages the crops are overcome, and the fixed-point quantitative hole-application deep-application operation of a chemical fertilizer can be carried out in the normal running process of the plough.

Description

High frequency fixed point fertilizer deep placing device

Technical field the utility model relates to a kind of farm implements, promptly a kind of high frequency fixed point fertilizer deep placing device that is suitable for the seeding corn and other crops topdressing operation.

It is existing a lot of that background technology is that dry crop such as corn imposes the farm implements of chemical fertilizer, and these facility are made of fertile case and following fertilizer mechanism, are articulated in the operation of applying fertilizer on the agricultural plough.In order to give full play to fertilizer efficiency, people wish chemical fertilizer can fix a point, quantitatively, deep placement, spread manuer in holes.At present, can accomplish quantitatively, deep placement, the facility of spreading manuer in holes be existing multiple, but can accomplish the also few of spot application.Said spot application is sprinkling upon chemical fertilizer near definite position of plant exactly, accomplish that this point just must be able to discern the position of plant, and this is very very difficult.For this reason, there is the people on facility, to install swing-bar mechanism additional, promptly with a side of stretching to plough, and the thin bar that can swing, between advancing, collides and swing, and then drive the fertilizer mechanism action, chemical fertilizer is spread down with crop plant., this facility adaptability when operation is relatively poor, occurs the problem that hunting frequency is too low or impulsive force is too big often.Its reason mainly is a fork returning device poor-performing, can not satisfy job requirement.At present, the return of fork all is to realize by the pulling force of spring.In order to guarantee fork return in time, spring just must have enough pulling force., pulling force is big fork will injure crop plant.Topdressing season of corn, plant is relatively more fragile, is easy to injure, so the pulling force of spring can not be too big, the fork swing speed can not be too fast, and plough can not be advanced fast.In addition, because the architectural characteristic and the power transmission rule of spring have determined that the back and forth flexible frequency of spring can not be too high, mechanical efficiency also is lower, that is to say, the loss of pulling force is bigger, and the pulling force of loss will act on crop plant, causes the impact of plant.Therefore, adopting spring is unaccommodated as the power of this swing-bar mechanism.

It is higher that the summary of the invention the purpose of this utility model provides a kind of hunting frequency of fork, but impulsive force is very little, plough under the situation of normally advancing, the high frequency fixed point fertilizer deep placing device that crop plant can not damage.

Above-mentioned purpose is realized by following technical scheme: develop a kind of high frequency fixed point fertilizer deep placing device, also be to constitute by fertile case, defertilizing tube, switch, backguy, fork etc., swing by fork drives backguy and switch motion control fertilizer, and is articulated in the operation of applying fertilizer on the plough.Different is: at the epimere of said switch, a balancing weight is arranged.

The front of said defertilizing tube is provided with a crooked plow standard of erectting, and is provided with earth separation plate below rectangular porose connecting plate of plow standard upper end horizontal, plow standard, and plough is equipped with in the lower end.

Adopt the high frequency fixed point fertilizer deep placing device of such scheme, balancing weight is at the drop-down movable pendulum bar of action of gravity return, and existing higher frequency can not cause too big impact again, and adaptability is stronger, can carry out the fertilising operation of crop in normally the advancing of plough.

Description of drawings embodiment of the present utility model is provided by the following drawings.

Fig. 1 is the front view of embodiment;

Fig. 2 is the front view of embodiment;

Fig. 3 is the left view of embodiment;

Fig. 4 is the force analysis figure of embodiment;

Fig. 5 is the duty front view of embodiment;

Fig. 6 is the duty vertical view of embodiment.

Among the figure as seen: fertile case 1, defertilizing tube 2, switch 3, balancing weight 4, switch shaft 5, plow standard 6, earth separation plate 7, plough 8, connecting plate 9, tappet 10, backguy 11, fork 12, fork axle 13, the plough 14, installing rack 15.

Embodiment is introduced a kind of embodiment below in conjunction with accompanying drawing.

As Fig. 1,2, shown in 3, this fertilizer applicator also is provided with defertilizing tube (2) below fertile case (1), be provided with switch (3) below the defertilizing tube, switch (3) middle part is connected on the defertilizing tube (2) by switch shaft (5), match with the opening of defertilizing tube in its underpart, top is provided with a balancing weight (4), the upper end links to each other with backguy (11) one ends, defertilizing tube (2) front is connected one and erects on the slightly curved plow standard (6), the porose connecting plate of bar shaped (9) is arranged above the plow standard, earth separation plate (7) and plough (8) are housed below, plow standard (6) epimere is equipped with the tappet (10) that stretches forward, and tappet (10) front end is equipped with a fork (12) that stretches laterally by fork axle (13).The small end of fork (12) links to each other with the other end of backguy (11).During work, as Fig. 4, shown in 5, be connected two fertilizer applicators on the installing rack (15) of plough (14) by connecting plate (9), the both sides that are placed in and plough, the plough advance between, plough (8) is left two ditches in the ranks crop, and fork (12) overcomes the gravity of balancing weight (4) and swing backward when running into the plant root, draw back switch (3) by backguy (11), chemical fertilizer is discharged by defertilizing tube (2), and subsequently, fork (12) slips over the crop cane, rapid return under the effect of balancing weight (4), defertilizing tube (2) is closed, and meets next strain crop up to fork (12), repeats above-mentioned action again.Be sprinkling upon the soil that the chemical fertilizer in the ditch just slipped over earth separation plate and fall after rise subsequently and cover, like this, just can realize chemical fertilizer fixed point, quantitative, deep placement, spread manuer in holes.Particularly during operation, carry out this topdressing operation, can better cover, thereby prevent the volatilization of nitrogen, improve the availability of chemical fertilizer in intertillage.
