Изобретение относитс к области сельского хоз йства, в частности к устройствам дл определени сопротивлени почвы рабочих органов роторного рыхлител .The invention relates to the field of agriculture, in particular, to devices for determining the soil resistance of the working bodies of a rotary ripper.

Известно устройство, которое познол ет определ ть сопротивление грунта при перемещении штампа в двух плоскост х: вначале при вдавливании штампа в глубь почвы, а затем при пе-О ремещении его в горизонтальной плоскости , 1 .A device is known which allows to determine the resistance of the soil when the stamp is moved in two planes: first, when the stamp is pressed into the soil, and then when it is moved — in the horizontal plane, 1.

Однако названное устройство не позвол ет измер ть сопротивление и деформацию почвы при внедрении долот и 15 отрыве пластов от массива в соответствии с процессом, выполн емьм роторным рыхлителем почвы.However, the said device does not allow to measure the resistance and deformation of the soil during the introduction of bits and 15 separation of the layers from the mass in accordance with the process performed by the rotary soil ripper.

Основными операци ми рыхлени почвы роторным рыхлителем вл ютс внед-М рение в почву на значительную глубину (соответствующую глубокой обработке ) группы долот и вслед за этим OTJ рыв от массива почвы пластов различг ной толщины перемещением долот по 25 криволинейной траектории, и оценивать правильно характер протекани всего, процесса можно лишь в том случае, если полностью имитировать работу роторного рыхлител без нарушени 30The main operations of soil loosening with a rotor loosener are the introduction of a group of bits into a soil at a considerable depth (corresponding to deep processing) and, following this, from the soil array of layers of varying thickness moving the bits along 25 curvilinear trajectories, and correctly assess the flow pattern of all, the process is possible only if completely imitating the work of the rotor ripper without disturbing 30

последовательности измерени составл ющих-его операций. При этом необходимо регистрировать вначале сопротивление и перемещение долот при внедрении их вглубь почвы и сразу вслед за этим - при отрыве .пластов.Sequences of measurement of components. At the same time, it is necessary to register first the resistance and movement of the bits when they are inserted deep into the soil and immediately thereafter - when plastics are separated.

Цель изобретени - определение оптимальных параметров рабочих органов роторных почвообрабатывающих машин , дл измерени сопротивлени почвы усилию отрыва пластов от массива ..The purpose of the invention is to determine the optimal parameters of the working bodies of rotary tillage machines for measuring the resistance of the soil to the force of separation of layers from the massif.

Достигаетс этом тем, что на валу поворотного узла закреплен рычаг с тензодатчиком, датчиком угла поворота и силовым цилиндром, закрепленным на каретке.This is achieved by the fact that a lever with a strain gauge, angle of rotation sensor and a power cylinder mounted on the carriage is mounted on the shaft of the rotary assembly.

Claims

The device comprises a frame 1, a plate 2 with forces by a cylinder 3 for moving the carriage 4. On the carriage are fixed supports 5 in which a swivel unit is mounted. The swivel assembly contains a slider 6 and a shaft 7. The rods 8 are fixed to the shaft with a beam 9 and the bits 10 placed on it, and the lever 11 supplied with a tone / (otschinom (on the drawings are not seen) see the resistance of the soil at separation of layers from the massif, and sensor 12 for measuring the angle of rotation of the lever 11. The cylinder 1.3 is designed to move the lever 11. On the carriage 4 above the slider 6 an electrical mass 14 and an electric pulse sensor 15 are fixed. The device works as follows: From the tractor cab to which the device is hung, help The hydraulic distributor controls the operation of the power cylinders. When the power cylinder 3 is turned on, the carriage 4 moves from top to bottom. Soil resistance to the introduction of bits 10 is transmitted to the slider b, and away from it to the electric meter 14. At this time, the electric pulse sensor 15 marks the displacement bits lO into the depth of the soil. The signals from the mass-dose 141 and the sensor 15 are transmitted to a recording device (not shown in the drawings). Then separation of the layers from the array is carried out. When the cylinder 13 is turned on, the lever 11 rotates at a certain angle, which rotates the shaft 7 fastened to it and the connecting rods 8 mounted on the shaft 8 with the beam 9 and the bits 10 installed on it. from the array is perceived by a strain gauge (not shown) mounted on lever 11, and the angle of rotation of lever 11 is sensed by sensor 12. Signals from these sensors are also transmitted to a recording device. Apparatus of the Invention A device for determining soil resistance to the introduction of working bodies of rotary tillage machines, including a frame, a slab, an electric tram carriage, an electric pulse sensor, supports for a rotary unit, a shaft with a connecting rod, and a beam with bits, characterized in that For measuring the resistance of the soil to the force of separation of layers from the massif, a lever with a strain gauge, a rotation angle sensor and a power cylinder mounted on the shaft from the rotary unit is fixed m on the carriage.
