(54) BUCKET EXCAVATOR T-shaped levers with rolling pins 6 and 7, which interact with each other. The plungers 8 are supported in the upper position between the plunger head and the pump casing 9. The inner arms 10 and 11 of the levers fixed in the hinges of-12 pillars communicate with each other by means of springs 13. The holes 14 of the first row of pumps 9 are connected by pipe 15 in the perforations 16 and 17 second row of pumps 9. The working fluid is placed in a barrel fixed on the handle, and a remote-controlled electromagnetic hydraulic valve can be placed between the tank and the pipeline, which is turned on from the excavator's cabin. Capacity, handle and valve are not shown in the drawings. The device works as follows. When the bucket 1 is covered by the bottom 3 (Fig. 1), the loops 4 with the rolling pin 6 press on the plungers 8 of the lower row of pumps 9, compressing their springs 13, and the plungers 8 are moved to the lower position (Fig. 2 and 3), the holes 14 in the pumps 9 overlap. The shoulder 10 presses from below on the extended shoulder 11 of the rolling pin 7, which presses on the plungers 8 of the upper row of pumps, compressing the springs 13, the plungers 8 are also moved to the lower position and block the openings 14. When the electromagnetic hydraulic valve is turned on the liquid from the tank through the same valve will enter the holes 14 of the pump 9 through pipelines 15. When opening the bottom 3 (Fig. 4), the latter, rotating on the fly 4 in the hinges 5, will release the rolling pin 6 and the plungers 8 on the bottom of the pump 9, and the springs 13 (Fig. 5 and 6) lift it and the plungers 8 up, opening the holes 14. Rotating at the hinges of the 12 pillars, shoulder 10 goes down. freeing the shoulder 11, and under the action of the springs 13 of the upper row of pumps 9, the plungers 8 move upward, opening the holes 14, and move the rolling pin 7 to the upper position, rotating in the posts of the hinge 12, the shoulder 11 is allowed to fall onto the shoulder 10. The holes 14 will enter the cavity under the plungers 8. When the bottom 3 is closed, loops 4, turning in the hinges 5, lower together with the rolling pin 6 on the plungers 8, moving down and compressing the springs 13. and 17 of the lower row of pumps 9 liquid sprays inside Renny bucket walls. Growing up in hinge 12, shoulder 10 rises up and lifts up shoulder 11, which, moving in hinge 12, rolling pin 7, will move plungers 8 to the lower position, compressing the springs 13, squeezing out fluid at a high speed through holes 16 and 17 of the second row pumps 9 to the inner walls of the bucket 1. The holes 14 are blocked by the plungers 8, and no liquid will flow under the plungers 8. At this time, the soil is harvested with the aid of one. The cycles are repeated. If it is necessary to cover the inner walls of the bucket abundantly with liquid, before the ground is collected, the bottom 3 of the bucket 1 opens and closes several times. Claims of an excavator, including front and rear walls, a bottom hinged to the body of the bucket, and a device for applying a protective liquid layer on the inner surface of the bucket, characterized in that, in order to increase efficiency by using the energy of the inertial forces of the bottom, the bucket, the device for applying a protective liquid layer made in the form of double-arm levers hinged on the back wall of the bucket, the inner shoulders of which are mounted so that they can interact with one another and the outer shoulders rest on the spring-loaded plungers of the pumps, which are mounted on the back wall of the bucket.
