Transplanter

Abstract

Provided is a transplanter capable of detecting the inclination of a transplanter body in the front-rear direction, interrupting the operation when a problem may occur in the operation, preventing thedisorder of the transplanting posture of seedlings, and preventing the transplanter body from being damaged. Travelling wheels (44) and planting hoppers (20a, 20b) are arranged on a travelling vehicle body, and earthing leveling wheels (37) are arranged on the rear portion of the travelling vehicle body in a free rotating mode. An earthing leveling wheel (37) for leveling the soil around the seedlings planted in the planting hoppers (20a, 20b). The transplanter is provided with tilt sensors (194, 194). The inclination sensors (194, 194) that come into contact with the soil-covering leveling wheel (37) when the inclination angle of the traveling vehicle body is equal to or greater than a prescribed angle, and stop the transmission to the traveling wheels (44) and the planting hoppers (20a,20b).

Description

technical field [0001] The invention relates to a transplanting machine for vegetable seedlings such as onions or lettuces. Background technique [0002] Conventionally, there is known a transplanter which transplants the seedlings injected|thrown-in to the seedling supply apparatus to a field using the seedling planting apparatus (patent document 1). [0003] The transplanter is provided with an inclination sensor for detecting the inclination of the body in the left and right direction, and the swing cylinder is extended and contracted based on the detection of the inclination sensor, so that the posture of the body is kept horizontal with respect to the ridge surface. Thereby, since the seedling planting apparatus maintains the attitude|position substantially perpendicular|vertical with respect to a ridge surface, it prevents that the planting attitude|position of a seedling is disturbed.

AI Technical Summary

Problems solved by technology

[0007] However, in the transplant machine of Patent Document 1, although the inclination of the body in the left-right direction, that is, the swing direction is detected, and the posture of the body is kept horizontal by the automatic expansion and contraction of the swing cylinder, the inclination in the front-rear direction of the body, that is, the pitch direction is not detected.

[0008] Therefore, the seedling planting device adopts a forward-inclining posture or a backward-inclining posture with respect to the ridge surface, and the seedlings are planted in a posture inclined forward or backward, and there is a problem that the seedling planting accuracy decreases.

In addition, depending on the angle, the seedlings planted obliquely will fall down due to their own weight or wind, so the operator needs to replant them manually, which causes a problem that requires extra labor and time.

[0009] In addition, when the angle of inclination is large, the body cannot maintain balance and falls, and the seedling supply device or the seedlings on the body fall to the field, causing problems that the seedlings are injured and are not suitable for transplantation, and it takes extra labor and time to collect the seedlings.

In addition, when it falls down, various parts of the machine body are damaged, making it impossible to continue the work, and there are problems that extra time and cost are required for repair
