Abstract

The utility model is a topdressing device for crops such as corn. It is composed of a fertilizer box 1, a fertilizer outlet 2, a swing arm fertilizer delivery pipe 3, a fertilizer spreading port 4, a contact switch 5, a rotating shaft 6, a clamping plate 7, an outward swing limit pin 8, etc. One end of the fertilizer delivery pipe 3 is connected to the fertilizer box by a rotating shaft, tilted outward and downward, and can swing left and right according to the change of crop row spacing. The other end is provided with a fertilizer spreading port and a contact switch, which can position and apply fertilizer after touching the crop stem. Since the swing arm swings without the action of spring force, the crop will not be damaged. Since the contact switch is very small and the switching speed is very fast, the problem of large spring force damaging the seedlings and small force slow switch return existing in similar machines is avoided.

Description

Swing arm location fertilizer placement drill

The utility model is a kind of farm machinery, promptly a kind of swing arm location fertilizer placement drill.

At present, the machinery that topdresses of dry crop, particularly corn is existing multiple.Wherein, the stalk fertilizing equipment of releasing in recent years that touches is welcome by the peasant deeply.Swing drive switch topdressed after the feeler lever of this fertilizer applicator was run into the crop cane, thereby can realize the seedling fertilising, and no seedling does not apply fertilizer, fertilizer placement and adjustable number, and effect is better., the feeler lever of this fertilizer applicator and switch are controlled by a spring.Spring strength is too little, and feeler lever return speed is slow, is not easy to hinder seedling too greatly again.Therefore preventing to hinder seedling and improving feeler lever return speed is the key issue of this fertilizer applicator.

The purpose of this utility model is a kind of feeler lever no seedling injury of development, again can returning quickly, and switch is flexible, and is simple in structure, cheap a kind of novel fertilizer applicator.

Technical scheme: this fertilizer applicator also has a fertile case, below the fertile case fertilizer-supplying port is arranged, fertilizer-supplying port connects fertilizer delivering pipe, different is, said fertilizer delivering pipe is to be connected on below the fertile case by rotating shaft, the swing arm fertilizer delivering pipe that tilts and can swing outwards, the end of pipe is provided with the broadcast application mouth, and the broadcast application mouth is provided with switch contacts.

Said swing arm fertilizer delivering pipe can have two, places both sides, fertile case below respectively, and every swing arm all has two amplitude of oscillation spacer pins, and is in maximum subtended angle position by deadweight promotion swing arm.

The fertilizer placement drill that adopts such scheme to make, the action of its swing arm is controlled without spring, only outwards opens by deadweight, runs into cane and comes closer, and is light flexibly, under certain speed, can not hinder seedling.In addition, be located at the broadcast application mouth of fertilizer delivering pipe one end, the contact of its gauge tap is very little, thereby, run into crop and swing immediately, return immediately again after the past, return speed is very fast.Thereby solved prior art problems preferably, and had characteristics such as simple in structure, cheap.

Introduce a kind of embodiment below in conjunction with accompanying drawing:

Fig. 1 is the front view of present embodiment, and Fig. 2 is its left view, and Fig. 3 is its vertical view, and Fig. 4 is its local amplification inclinating view.

Fig. 5 is the user mode schematic diagram of present embodiment.

Have among the figure: fertile case 1, fertilizer-supplying port 2, swing arm fertilizer delivering pipe 3, broadcast application mouth 4, switch contacts 5, rotating shaft 6, clamp 7, put spacer pin 8, interior pendulum spacer pin 9, the baffle plate 10 of switch contacts, rotating shaft 11, spring 12, contact 13 outward.

As seen from the figure, fertile case 1 both sides of this fertilizer placement drill big I that all has fertilizer-supplying port 2, a fertilizer-supplying port 2 is adjusted flow by plate control.Chemical fertilizer flows into two swing arm fertilizer delivering pipes 3 respectively from two fertilizer-supplying ports, linked to each other by rotating shaft 6 between fertilizer delivering pipe 3 and the fertile case, and outwards stretches out the below, becomes " eight " font.Do the time spent in no external force, two fertilizer delivering pipes outwards open by deadweight, are put spacer pin 9 outward and block.When advancing in the field, the crop cane on both sides is with after fertilizer delivering pipe contacts, fertilizer delivering pipe can in swing, the mistake with the friction of crop cane.In the end of fertilizer delivering pipe 3, a downward broadcast application mouth 4 is arranged, in its lower section, be provided with the baffle plate 10 of switch contacts, the baffle plate other end is connected on the fertilizer delivering pipe by rotating shaft 6, and by a spring, is located in the closed position, promptly blocks broadcast application mouth 4.On baffle plate, protrude a contact 13, when swing arm fertilizer delivering pipe and crop cane nuzzled up, contact was touched and the pressure that overcomes spring 12 rotates and pushes baffle plate open, opens the broadcast application mouth, behind the broadcast application, return is immediately blocked fertile mouthful of retaining again.Because contact is very little, short time of contact with cane, thereby, avoided hindering the problem of seedling with regard to having solved existing facility spring force and return contradiction between speed like this as long as very little spring force can be worked fast.

Claims

1, fertilizer placement drill is located in a kind of swing arm, a fertile case (1) is also arranged, below the fertile case fertilizer-supplying port (2) is arranged, fertilizer-supplying port connects fertilizer delivering pipe (3), it is characterized in that: said fertilizer delivering pipe is that an end is connected under the fertile case by rotating shaft (6), the swing arm fertilizer delivering pipe (3) that tilts and can swing outwards, the other end of swing arm fertilizer delivering pipe (3) is provided with broadcast application mouth (4), and broadcast application mouth (4) is provided with switch contacts (5).

2, fertilizer placement drill is located in swing arm according to claim 1, it is characterized in that: said swing arm fertilizer delivering pipe (3) can have two, place both sides, fertile case below respectively, every swing arm all has in an outer pendulum spacer pin (8) and one puts spacer pin (9), and swing arm is in maximum subtended angle position by the deadweight promotion under nature.
