Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1, the utility model discloses a spiral cable device for sprinkling irrigation machine, including motor 1, reduction gear 2, the tight structure of self-adaptation and cable roller 3, motor 1 is connected with the cooperation of reduction gear 2, and reduction gear 2's output shaft and self-adaptation fastening structural connection, reduction gear 2 adopt current suitable reduction gear 2 can, it can slow down the rotational speed of motor 1 output to still have the effect of promoting the moment of torsion.

Referring to fig. 1-3, the adaptive fastening structure includes an outer sleeve 4 and an inner sleeve 5, a plurality of slip rings 6 and sliding grooves are disposed between the outer sleeve 4 and the inner sleeve 5 and are in sliding fit, the slip rings 6 and the sliding grooves are matched to achieve a limiting effect, a plurality of sets of ratchets 7 and pawls 8 are disposed between the outer sleeve 4 and the inner sleeve 5, the ratchets 7 and the pawls 8 are matched, the ratchets 7 and the pawls 8 achieve a main cable tightness adjusting effect, when the cables rotate clockwise, if the cables are over-tightened, the outer sleeve 4 idles under the action of the ratchets 7 and the pawls 8, and since the ratchets 7 and the pawls 8 can bear a part of force which just enables the cables to be wound on the cable roller 3 with a relatively tight effect and exceeds the force, the ratchet 7 and the pawls 8 operate to prevent the cables from being pulled due to over-tightening, the pawls 8 between the ratchets 7 and the pawls 8 are all of a plurality of and are uniformly disposed, the ratchets 7 and pawls 8 are more stable, the left end of the inner sleeve 5 is provided with a connecting block 9, and connected to an output shaft of the speed reducer 2, the outer sleeve 3 is mounted on the outer sleeve 3, the outer sleeve 4, a baffle 4, a left baffle plate 10 and a right baffle plate 4 is provided with a left baffle plate 10, and a right baffle plate 10 for fixing block 11 for fixing the cable roller 4, and a left end of each cable roller 3, and a left baffle plate 10 are connected with a left baffle plate 10, and a right baffle plate 12 for fixing block 11, and a cable roller 3, and a cable roller 10, and a cable 3 are connected with a cable 11, and a cable 3, and a cable 11 for fixing block 12.

The left end of the left baffle 10 is provided with a collecting ring 13, the right end of the speed reducer 2 is provided with a connecting plate 14 and a plurality of brushes 15, the plurality of brushes 15 are matched with the collecting ring 13, the collecting ring 13 is electrically connected with electric wires on the cable roller 3, the collecting ring 13 and the brushes 15 slide, power supply transmission is realized while rotation is realized through the action of the collecting ring 13 and the brushes 15, and as the surface of the collecting ring 13 is smooth, a dust cover 16 is arranged around the collecting ring 13 and the connecting plate 14 and used for covering most of dust, and the dust cover 16 is arranged at the right end of the speed reducer 2.

When the cable coiling device for the sprinkling machine is used for uncoiling, the motor 1 and the speed reducer 2 are controlled to operate, the output shaft of the speed reducer 2 rotates anticlockwise, the cable roller 3 continuously rotates anticlockwise under the action of the ratchet wheel 7 and the pawl 8, and cables are uncoiled,

when the cable is wound, the motor 1 and the speed reducer 2 are controlled to operate, the output shaft of the speed reducer 2 rotates clockwise, the ratchet wheel 7 and the pawl 8 can rotate between the pawl 8 and the ratchet wheel 7 only under the elastic action of the pawl 8 and need to meet a certain force, when the force is not met, the outer sleeve 4 and the inner sleeve 5 can rotate simultaneously, the cable is wound at the moment, when the winding of the cable roller 3 is too tight, the force between the ratchet wheel 7 and the pawl 8 can meet the rotating condition between the ratchet wheel 7 and the pawl 8 under the pulling force of the cable, the ratchet wheel 7 and the pawl 8 rotate relatively at the moment, and therefore the outer sleeve 4 and the inner sleeve 5 are idled, the phenomenon that the cable is too tight is relieved, and the effect of automatically adjusting the cable winding compactness is achieved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
