Direct seeding device

Abstract

The invention provides a direct seeding device, which can improve the control degree of the seeding depth by arranging a hard-soft sensor (114). The invention is characterized in that a direct seeding device (82), which is freely arranged at the rear portion of a running car body (12) relative to the running car body by the elevating of an elevating hydraulic cylinder (46) and an elevating connecting lever device (3), has transfer pipes (93, 95) for respectively transferring the seeds to a farmland, floats (55, 56) are arranged at the lower part of the direct seeding device (10), ground-leveling tools (27a, 27b) are freely arranged relative to the elevating of the direct seeding device (82), the ground-leveling tools (27a, 27b) are arranged in front of floats (55, 56) to contact the ground for levelling the ground, and a soft-hard sensor (114) for detecting the soft-hard degree of the farmland is arranged between the floats (55, 56) and the ground-leveling tools (27a, 27b).

Description

technical field [0001] The present invention relates to a direct seeding machine provided with a powder or grain discharger such as a fertilization device, a seeding device, or a chemical spraying device. Background technique [0002] In the past, such a live broadcast machine is known: a plurality of powder output units are arranged side by side along the left and right direction of the body on the rear side of the seat of the traveling vehicle body, and a box for storing powder is provided above the powder output unit. It is equipped with a powder or granular body discharge machine that sends the powder or granular body sent out from the powder or granular body output part through the air blowing from the blower and continuously discharges it to the cultivated land, and supports the above-mentioned powder or grain body output by a plurality of floats that slide on the cultivated ground. part, and arranged in the left and right direction of the body. [0003] In addition, ...

Problems solved by technology

[0007] In the above-mentioned Patent Document 1, since the soft and hard sensor is not provided in the seedling planting device, the hardness of the cultivated land cannot be detected, and the seedling planting depth cannot be controlled according to the degree of hardness of the cultivated land.

[0008] In addition, although the above-mentioned patent document 2 discloses a structure capable of controlling the seedling planting depth according to the detection value of the soft and hard sensor of the seedling planting machine, since the soft and hard sensor is directly installed on the center float, the value detected by the soft and hard sensor The detection value of cultivated land hardness is easily affected by the float that touches the cultivated land with a relatively large contact area, and it may not be able to accurately detect the hardness of the cultivated land
