(54) УСТРОЙСТВО ДЛЯ РАЗРУШЕНИЯ ПОЧВЕННОЙ КОРКИ(54) DEVICE TO DESTROY SOIL CORK

1one

Изобретение относитс к сельскохоз йственной технике, в частности к почвообрабатывающим устройствам, предназначенным дл разрушени почвенной корки.The invention relates to an agricultural technique, in particular, to soil tillage devices designed to destroy a soil crust.

Известны устройства дл разрушени почвенной корки, включающие дисковые батареи 1.Devices for destroying soil cover are known, including disk batteries 1.

Эти устройства про извод т сильное смещение верхнего сло почвы и поэтому не пригодны дл обработки почвы на посевах .These devices produce a strong displacement of the upper soil layer and are therefore not suitable for tillage on crops.

Известно также устройство дл разрушени почвенной корки, включающее раму с закрепленной на ней осью с дисками 2.It is also known a device for destroying a soil crust, comprising a frame with an axis fixed to it with disks 2.

Недостатком его вл етс повреждение всходов сем н при обработке почвы над линией посева.The disadvantage of it is damage to seedlings when cultivating the soil above the sowing line.

Цель изобретени - предотвращение повреждени всходов сем н при обработке почвы над линией посева.The purpose of the invention is to prevent damage to seedlings when cultivating the soil above the sowing line.

Эта цель достигаетс тем, что диски соединены между собой пальцами, на которых закреплены свободно вращающиес ножи, выполненные звездчатыми, при этом ось с дисками снабжена вибратором и подпружинена .This goal is achieved by the fact that the disks are interconnected by fingers, on which free-rotating, star-shaped knives are fixed, while the axis with the disks is equipped with a vibrator and is spring-loaded.

На фиг. 1 изображенЪ предложенное устройство; на фиг. 2 - то же, разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.FIG. 1 shows the proposed device; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

Устройство дл разрушени почвенной корки имеет раму 1, на которой посредствомThe device for destroying the soil crust has a frame 1 on which, by means of

5 пружин 2 и 3 смонтирована пола ось 4 с установленными на ней дисками 5. Диски 5 закреплены на оси 4 с возможностью свободного вращени посредством ступицы 6. Диски 5 дополнительно соединены между собой пальцами 7, размещенными по кон10 центрической окружности 8. На пальцах 7 установлены свободно вращающиес ножи 9, выполненные в поперечном сечении звездчатыми, например четырехгранными. Внутри полой оси 4 в подщипниках 105 springs 2 and 3 are mounted to the floor axis 4 with discs 5 mounted on it. Disks 5 are fixed on axis 4 with the possibility of free rotation by means of hub 6. Disks 5 are additionally interconnected by fingers 7 placed along a concentric circle 8. On fingers 7 are mounted freely rotating knives 9, made in the cross-section of star-shaped, for example tetrahedral. Inside the hollow axis 4 in the support 10

5 закреплен вал И с вибратором, выполненным в виде установленных на концах вала щкивов 12 с эксцентричным центром т жести . Привод щкивов 12 осуществл етс посредством ременной передачи 13, редуктора и карданного вала от ВОМ трактора5, the shaft is fixed And with a vibrator, made in the form of shkivy 12 installed on the shaft ends with an eccentric center of gravity. The drive of the Shkivs 12 is carried out by means of a belt drive 13, a gearbox and a drive shaft from the tractor PTO shaft.

Claims

The device works as follows. The device is lowered onto the soil so that the sowing line is located between the discs. When the machine is moving, the disks 5 are buried in the soil and are rolled over due to adhesion with the soil. In this case, the disks 5 cut the soil along the row of sowing at the borders of the protective zone. The rotating discs 5 entangle the star-shaped knives 9 associated with them, which roll over a strip cut by the discs 5 and loosen a soil crust. Due to the compression of the soil between the adjacent edges of the knives 9, the degree of its crushing increases. Caused by rotating pulleys 12 with an eccentric center of gravity, the vibration is transmitted from the edges of the knives 9 to adjacent layers of soil and promotes uniform soil loosening in depth. Due to the spring-loaded axis 4, the sharpness of the impact of the knives 9 on the soil is reduced. The edges of the knives 9 enter and leave the soil gradually, without scattering soil particles and displacing the PMU / 7, venous layers, which prevents damage to the seedlings of the plants. An apparatus for destroying soil crust, including a frame with an axis with discs fixed on it, characterized in that, in order to prevent damage to seedlings when tilling the soil over the yosev line, the discs are interconnected with their fingers, on which freely rotating knives are fixed, made star-shaped, with the axis with the disks equipped with a vibrator and spring loaded.
