Изобретение относитс к землеройкотранспортным машина.м.The invention relates to a land transport vehicle m.

Наиболее близким к предлагаемому техническим решением вл етс скрепер с канатной т гой, включающий ковш с боковыми и задней стенкой, оснаш.енной зубь ми The closest to the proposed technical solution is a cable-type scraper, including a bucket with side and rear wall, equipped with teeth

Недостаток этого скрепера заключаетс в том, что дл перемещени наполненного ковша требуетс значительное т говое усилие из-за наличи дополнительного сопротивлени , возникающего на зубь .х ковша.The disadvantage of this scraper is that considerable pulling force is required to move the filled bucket due to the additional resistance that occurs on the tooth of the bucket.

Цель изобретени - уменьшение сопротивлени перемещению наполненного ковша путем убирани зубьев.The purpose of the invention is to reduce the resistance to movement of the filled bucket by removing the teeth.

Это достигаетс тем, что в скрепере с канатной т гой, включающем ковш с боковыми и задней стенкой, оснащенной зубь ми , задн стенка выполнена в виде свободно насаженных на горизонтальную ось, прикрепленную к боковым стенкам ковша, пластин , у каждой из которых вес нижней относительно оси вращени части так относитс к весу ее верхней части, как лобова площадь верхней части пластины относитс к лобовой площади ее нижней части, причем ковщ оснащен упорами, расположеннымиThis is achieved by the fact that in the scraper with cable traction, which includes a bucket with side and rear wall equipped with teeth, the rear wall is made in the form of freely mounted on a horizontal axis attached to the side walls of the bucket, plates, each with a lower weight the axis of rotation of the part relates so to the weight of its upper part, as the frontal area of the upper part of the plate relates to the frontal area of its lower part, and the bucket is equipped with stops located

сзади пластин выше и ниже оси их вращени .rear plates above and below their axis of rotation.

На чертеже изображен предлагаемый скрепер, продольный разрез.The drawing shows the proposed scraper, longitudinal section.

Скрепер содержит ковш I с боковыми 2 и задней 3 стенками. К ковшу прикреплены канаты пр мой 4 и обратной 5 т ги. Задн стенка выполнена в виде отдельных плас« тин, свободно насаженных на горизонтальную ось б, прикрепленную к боковым стенклм KOBnia.. Кажда пластина содержит верхнюю 7 и нижнюю 8 части, при этом нижние , части пластин оснап1ены зубь ми 9, а на ковше сзади пластин выше и ниже оси их вращени выполнены ограничительные упоры 10 и 11. Причем пластины, составл ющие заднюю стенку 3 ковша, выполнены так, что у каждой из них вес нижней относительно оси вращени части 8 так относитс к весу верхней части 7, как лобова площадь верхней части пластины относитс к лобовой площади ее нижней части. Устройство работает следующим образом .The scraper contains a bucket I with side 2 and rear 3 walls. The ropes are attached to the ladle, straight 4 and reverse 5 tons of gi. The back wall is made in the form of individual plates, loosely mounted on the horizontal axis b, attached to the side wall KOBnia .. Each plate contains the top 7 and bottom 8 parts, while the bottom, parts of the plates are equipped with teeth 9, and on the bucket behind the plates above and below their axis of rotation, restrictive stops 10 and 11 are made. Moreover, the plates constituting the back wall 3 of the bucket are made so that each of them has a weight lower than the axis of rotation of the part 8 so that the weight of the upper part 7 relates to the front plate parts Sits to the frontal area of its lower part. The device works as follows.

Claims

In the initial position, under the action of the moment of gravity of the plate, constituting the back wall of the bucket, the supports 11 are supported. When the scraper is moved by a pull rope 4, the material is destroyed by the teeth 9 and the bucket is filled with this material. As the bucket is stained, the material exerts an increasing force on the upper parts of the 7 plates and, when the bucket is full, the force acting on the upper part of the plates exceeds the force acting on their lower part, which causes these plates to turn to the stop 10 and the teeth deepen. from the material. During the reverse movement of the scraper by means of the rope 5, the teeth of the plates are also inside the bucket, without interfering with its movement. Due to the fact that the rear wall of the scraper bucket is made in the form of unlaced PLASTIN not only reduces the resistance to movement of the filled bucket, but also simplifies its design by eliminating the drives for the excavation of the teeth. In addition, the use of the proposed I.1 invention will ensure that the material from the bucket is unloaded into a container using guides that will not be destroyed by the scraper teeth. Claims of the Invention Scraper with cable traction including a side and rear wall with teeth, characterized in that, in order to reduce the resistance to movement of the filled bucket by removing the teeth, the rear wall is made in the form of freely mounted on a horizontal axis attached to side walls, a bucket, plates, each of which has a weight relative to the axis of rotation of the part as it relates to the weight of its upper part, as the frontal area of the upper part of the plates refers to the frontal area of its lower part, and The bucket is equipped with stops located behind the plates above and below their axis of rotation.
