The invention is suitable for gardening tools and can be used for cleaning the area from leaves, paper, dried trase and the like.

The purpose of the invention is to increase productivity and facilitate construction.

FIG. 1 shows schematically the proposed device, the general view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. one; in fig. 5 is a sectional view BB in FIG. one; in fig. 6 is a view of FIG. 2

The device includes a cleaner 1 of teeth 2 of a comb 3 of a rake 4, also containing a cutting 5. Cleaner 1 is placed with possible movement between teeth 2 and contains slots 6 according to the number of teeth a slave; her. The guide 7 is rigidly fixed on the comb 3 with screws 8, while the crown gag 9 of the guide 7 is bolted 10 to the horizontal shelf 1 1 of the comb 3. The pusher 12, the bottom part 13 of which is rigidly connected to the wiper 1, is installed with vertical displacement. The device also contains a drive device 14 cleaner 1 with a return mechanism 15, made in the form of a torsion spring 16. The guide 7 is mounted on the comb 3 in the middle, and the lower part 13 of the pusher 12 is connected with the cleaner 1 in the central part of the cleaner 1. The drive device 14 of the cleaner 1 is made in the form of a double-arm lever 17, which is mounted on the sleeve 18 with a central hole 19, moreover, the sleeve 18 is rigidly fixed on one of the ends of the comb 3 rake 4.

A double-shouldered lever 17 is placed on the comb 3 rotatably in a plane parallel to the tooth m 2 of the comb 3. A sleeve 18 is inserted into the hole 20 on the comb 3 and is rigidly fixed on it with nuts 21 placed on its threaded end 22. One shoulder 23 of the two shoulders The lever 17, facing the center of the comb 3, is provided with a longitudinal groove 24, which interacts with a rod 25 rigidly fixed in the upper part 26 of the pusher 12. The end 27 of the other arm 28 of the double-arm lever 17 is curved in two mutually perpendicular planes, due to for it has a rounded shape. This provides the possibility of sliding it on the ground and makes it possible to clean the teeth of the rake without interrupting the work. The spring 16 of the return mechanism is located in the central hole 19 of the sleeve 18. The shoulder 23 of the double-armed lever 17 interacts with the curves of the right angle with the end 29 of the spring 16 and is spring-loaded in the direction of the lift of the cleaner 1. The opposite end 30 of the spring 16 cooperates with the comb 3,

the entrance to the hole 31, made in the horizontal shelf 11 of the comb. To facilitate the assembly, the sleeve 18 is made split along its axis, while in order to ensure the rigidity of the sleeve 18 in the assembled position, a cup 33 can be inserted into its slit 32.

Cleaner 1 is made solid and provided with transitional areas 34 located between sockets 6. Thus, each tooth 2 is surrounded on three sides by a nest 6 and elongated sides 35 of transitional areas 34. A rigid connection of the lower part 13 of the pusher 12 with the central part of the cleaner 1 5 with the help of grooves 36, made in the lower part 13 of the pusher 12 on its lateral sides. The grooves 36 interact with the respective elongated sides 35 of the transition portion 24 located in

0 center of the cleaner 1. In order to prevent the spontaneous elongated sides 35 of the central gearbox 1K) of the section 34 and the slots 36 of the pusher 12, the material of the cleaner 1 can be opened at the points “a. In go. Skirt 37 25, rigidly fastened5 in the upper part 26 of the pusher 12, Bbino: iHeiio hole 38, through which the bar 39 passes, iicTBi; 40 of which are rigidly connected to the ends, clean, 1 and perform the role of hard tons. The presence of iipyrKa 39 in the design of the device provides a more even distribution of forces along the length of the cleaner when pushing the cleaned mass out of the pro-spacers between the teeth 2 and avoids distortions of the cleaner 1 during operation. The double-shouldered lever 17 can occupy two extreme positions: the initial position "P - cleaner 1 is then moved to the upper position" B, and the working position "P - cleaner 1 while is in the lower position" N.

0 Work with the device is carried out as follows.

When working with rake 4 for cleaning the area, the operator can clean the teeth 2 from the stuffing material between them by pressing on the shoulder 28

5 levers 17. This can be done in several ways. For example, the operator can make a short stop during operation and press the shoulder 28 of the two shoulders with 17 legs or hands, thus clearing the tooth 2 from the blockage

 between the material. Or, when the rake is pushed towards itself, the operator must roll the comb 3 on its side, while the end 27 of the shoulder 28 of the two shoulders lever 7 due to the fact that it is curved in two J. mutually perpendicular planes begins to slide on the ground, and with further collapse comb 3 on its side, it is increasingly pressed against the ground, there is a rotation of the two shoulders lever 17 and a wipe

0

teeth 2 from material that is stuck between them. At the end of this movement, when the operator pulls the comb 3 towards him, it is completely cleaned, and when the rake 4 is detached from the ground, all elements of the fixture return to their original position. When the double-shouldered lever 17 rotates, with its groove 4, made in the shoulder 23 of the two-armed lever 17 and interacting with the rod 25 of the pusher 12, the pusher 12 moves downward in the guide 7. The cleaner 1 of the teeth 2 moves. the two shoulders of the lever 17, its arm 23 rotates and the curved end 29 of the spring 16 interacting with it, thereby loading the spring 16. At the end of the turn, the two shoulders lever 17 is transferred from the initial position "And to the final position" P, and the cleaner 1, which was initially in position "B" is in position "N. In this case, all the material that is packed between the teeth 2 of the comb 3, is pushed out of the weft bar between the teeth 2.
