Description

with electromagnets, made in the form of splines on a shaft, on which a turning nut is movably mounted, provided with a cup of magnetic material for interacting with electromagnets and having a transition to one another on the outer surface of the screw and longitudinal grooves, and in the housing perpendicular to the nut under the springy finger, stirring the key for nuts. Fig. 1 shows a schematic diagram of a device for distributing a nutrient solution about the proposed gold drive; Fig. 2 shows the drive with the lower index of the turn nut; Fig. 3 shows the drive with the nut in the middle position; Fig. 4 shows the drive with the nut in the upper position Fig. 5 shows the actuator in the middle position of the nut after turning it, in Fig. 6, section A-A of Fig. 2. The device includes a housing 1, in the center of which is located a shaft 2 with a distributor 3 fixed to it and having a knee-shaped channel 4. On the upper part of the shaft 2 fixed the coupling half, made in the form of slots 5 and 9, on which the nut of rotation 7 is movably mounted, is fitted on a hollow cup 8, which interacts with an electromagnet 9 installed in housing K1 of plate 1. Recess spring 11 is abutted in cup 8 and abutting with its lower end in nut -.turn 7, and the top - into the washer 12 rigidly fixed on the shaft 2. In order for the nutrient solution not to flow from the housing 1 into the ip cover between the shaft 2 and the housing, seals 13 are installed. In the housing 1 it is perpendicular to pivot 7 pivot nuts The hinge pin 14 and on the side surface of the turn nut are made one-to-one screw and longitudinal grooves 15, and the depth of one groove is greater than the depth of the other groove in the place of their coupling. The device works as follows. When an electric signal is applied from the control system to the electromagnet 9, the measles of the latter begin to draw in the cup 8, lift the nut 7 with it. The finger 14, the slide along the helical groove 15i causes the nut 7 to rotate about its axis at an angle corresponding to the screw groove. Through the splines 5 and 6, the rotational movement from the nut of rotation 7 is transmitted to the shaft 2 and, consequently, to the distribution spool 3, with the result that the knee-shaped channel 4 is aligned with one of the following outlets: housing holes, At the end of the movement 7 ki pivot pin 14 upwardly in place mating grooves 15 proceeds nz helical grooves in continuation hydrochloric}, because the depth of the longitudinal grooves | 1 so1f1 1zhenia screw kansshki more depth. After turning off the electromagnet 9 under the action of the return spring 11, the turn nut 7 is lowered along the splines 5 a 6 without rotation about its axis, since the finger 14 slides along the straight {groove groove. The entire device is prigoshcht to its original position. Sending a certain portion of the pitrbdjaego p to the section of the spool 3 turns to the required angle according to the description of the ao & the circuit and its channel 4 are aligned with another opening of the housing 1 for supplying the nutrient solution to the secondary section. From the previous section, M & A & solution. In the above described construction, the transformation of a reciprocating motion into rotational and its transmission to the shaft is combined in one device — the nut of rotation, and the drive and the valve are a single-piece, organically fused structure. The proposed spool drive allows simplifying the design and increasing the reliability of operation of the entire distribution device, eliminating a number of auxiliary links of a complex kinematic scheme of a known device of similar purpose. The formula of the spool actuator is predominantly of a water dispenser for distributing and supplying the nutrient solution to plants, containing a shaft with a spool rigidly mounted on it and a coupling, one pole of which is connected to the shaft, and the other interacts with electromagnets. TVl and h a and with the fact that, zselk) up. Simplification of its design; and improving reliability, the coupling half interacting with the electromagnets is made in the form of splines on the shaft, onto which a turn nut is movably mounted onto the turn nut, provided with a cup of magnetic material for interacting with the electromagnets and having screw and longitudinal grooves on the outer surface, A spring-loaded pin is mounted to the nut in the Pfpendiculum housing, moving along the grooves.
