SU79956A1 - Manual injector for soil treatment - Google Patents

Description

The invention relates to reciprocating devices for introducing poisonous substances into the soil.

Hitherto known manual injectors of this kind are equipped with a permanent needle syringe; their disadvantage is that the needle of the syringe is designed for an average density of the soil. Such a needle-like syringe creates considerable difficulties when using manual injectors on dense or too loose soils.

In the proposed injector, this disadvantage is eliminated by the presence of two changing needles, one of which (bayonets) is intended for loose soils, and the second, in the form of a drill, is solid soil, the rotation of which is carried out by a collar attached to the injector tank.

FIG. 1 shows a general view and a section of a manual injector; in fig. 2 shows the bottom of the injector with a bayonet needle; in fig. 3 and 4 - longitudinal and transverse sections of the bayonet needle; in fig. 5 - injector with a needle in the form of a drill; that fig. 6 is a cross-section along the line A-A in FIG. five.

The hand injector for dressing soil consists of a reservoir / having a tube 2 at the bottom, the needle 3 is screwed on its end. Granen Eagle (bayonet) provides the necessary resistance to buckling at its minimum cross-sectional area. A copper tube 5 is inserted into the channel 4 to protect the walls from corrosion. At the end of the needle 5, there are two holes 6, through which d are injected into the soil.

The step 7 is fixed on the collar 8 with the help of a hinge 9 and when pressed against it rests with its end 10 on the surface of the needle 3.

The needle is inserted into the soil by pressing on the footboard 7, which can mix along the needle, but with pressure and a small tserekos it can be retained in any part of the needle.

No 79956- 2 Inside the tank / mounted a metering mechanism for supplying fluid to the soil in certain portions, made in the form of a plunger pump. A sleeve // is inserted into the tube 2, which is tightly clamped between its tube and the needle with its protrusion 12. Inside the nest there is a spring-loaded plunger IS connected to the rod 14, at the lower end of which is the suction valve 15. The discharge valve 16, the valve spring J7 and the stopper 18 is mounted in the upper part of the needle 3. On impacting the head 19 of the bar 14, the suction valve 15 closes and pushes the plunger 13 down. The valve 16 opens and passes a certain dose of fluid into the channel 4 of the needle 3.

The dosage of the fluid is adjusted by setting the stroke of the plunger 13 by interchanging the ring 20.

For work on dense soils, the injector is equipped with a needle 21, which has an end in the form of a drill and is connected to the reservoir by means of a nut 22.

To rotate the needle 21, a gate 23 is used, connected in its lower part with a needle, and in the upper part - with a tank / using a steel collar 24 and a screw 25.

By rotating the gate, the needle 21 is freely submerged in dense soil.

Claims (2)

1. A manual injector for dressing a soil consisting of a cylindrical tank for dispensing a liquid poisonous substance supplied to the soil by doses through a needle syringe, characterized in that in order to destroy agricultural pests by pickling both loose and "compacted soils, the syringe is supplied two Replaceable needles - one bayonet-shaped for loose soils, and the other in the form of a drill with a fit for rotation in dense soils. 2. The form of execution of the injector according to claim 1, characterized in that the rotation of the drill-like needle is carried out by a collar, one end connected to the needle, and the other (with the help of the clamp) with the reservoir. 4 FIG. five -but ig.6
