Description

Изобретение относитс к машинам дл планировки грунта, используемьах при капиташьной и текущей планировке полей.FIELD OF THE INVENTION The invention relates to machines for ground planning, used in the field and current field planning.

По основному авт. св. № 606951 известен Длиннобазовый планировщик, включающий ргшу с установленным на ней ковшом с боковыми стенками и шарнирно установленными на них дополнительными стенками l.According to the main author. St. No. 606951 is known for the Long Base Planner, which includes a projectile with a bucket installed on it with side walls and additional walls hinged on them.

Установка дополнительных блоков стенок откидывающимис повышает планирующую способность планировщика путем исключени заглублени боковых стенок на поворотах, снижа при этом т говое усилие.The installation of additional wall units by flip-ups increases the planning ability of the planner by eliminating the deepening of the side walls when cornering, while reducing tractive effort.

Недостатком известного планировщика вл етс образование валика грунта с внешней стороны дополнительной стенки при выходе планировщика из поворота на пр мую, который -возникает вследствие запаздывани возврата дополнительной стенки в первоначальное положение из-за действи сопротивлени грунта, наход щегос с наружной стороны дополнительной стенки. Возврат дополнительной стенки может «йлть обеспечен собственным ее весом и дополнительным подпором грунта внутриA disadvantage of the known planner is the formation of a ground roller on the outer side of the additional wall when the scheduler exits from the turn to the straight, which arises due to the delay in returning the additional wall to its original position due to the resistance of the soil located on the outer side of the additional wall. The return of an additional wall can be provided by its own weight and additional ground support inside

ковша, превьшёиощим сопротивление грунта, наход щегос с наружной стороны ковша.bucket, greater than the resistance of the soil, located on the outside of the bucket.

Цель изобретени - повышение качества планировки на выходе планйровщнка из поворота на пр молинейный учасчок.The purpose of the invention is to improve the quality of the layout at the exit of the planner from a turn to the straight line.

Указанна цель достигаетс тем, что на дополнительных стенках установлены отражатели грунта в виде пластин, рабочие поверхности которых составл ют тупой угол с рабочей поверхностю дополнительных стенок, а лини пересечени последних перпендикул рна шарнирам дополнительных стенок.This goal is achieved by the fact that on the additional walls there are soil reflectors in the form of plates, the working surfaces of which make an obtuse angle with the working surface of the additional walls, and the line of intersection of the latter is perpendicular to the hinges of the additional walls.

При этом угол между рабочими поверхност ми отражателей и дополнительных стенок составл ет 135-165 .Here, the angle between the working surfaces of the reflectors and the additional walls is 135-165.

На фиг. 1 изображен планировщик, общий вид; на фиг. 2 - ковш; на фиг, 3 - разрез А-А на фиг. 2.FIG. 1 shows the scheduler, a general view; in fig. 2 - bucket; FIG. 3 is a section A-A in FIG. 2

Claims

The long-base level manager contains front wheels 1, frame 2, rear wheels 3, bucket 4 with side walls 5 and additional walls 6, KOTOE & i through the hinges 7 are mounted on the side walls 5 so that they can only be folded inside the bucket. On the additional side walls 6 fixed reflectors of the soil 8, made in the form of plates. The working surfaces of the reflectors 8, interacting with the ground, make an obtuse angle with the working surfaces of the additional walls b, and their intersection line is perpendicular to the hinges 7 of the additional walls 6. The obtuse angle between the working surfaces is 135-165. in the following way;. After the planner exits the turn, the external force on the additional wall is removed and it takes up a vertical position under its own gesture and, due to the backfill of the soil inside the bucket. This happens if at the moment of turning out of the turn, soil is dumped from the bucket to a lowering. If, however, the cutting of the ground occurs, then dl. the return of the additional wall to the initial vertical position requires an additional force, which is created by the reflectors when interacting with the ground. This force arises as a normal component of the soil cutting forces by an oblique wedge, i.e. working surface reflector. The forced return of the additional wall occurs after the planner leaves the turn to the straight section, thus eliminating the occurrence of rollers outside the bucket, thus eliminating the need for additional planner passes, which increases the quality and performance during planning. Claim 1, Long base scheduler according to author. No. 606951, in order to improve the quality of the layout at the exit of the planner from turning to the straight line section, on the additional walls there are soil reflectors in the form of plates, the working surfaces of which make an obtuse angle with the working the surface of the additional walls, and the lines of intersection of the latter are perpendicular to the hinges of the additional walls. 2, the scheduler according to claim 1, characterized in that the angle between the working surfaces of the reflectors and the additional walls is 135-165.
