Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a planter, for example, one for planting agricultural products such as potatoes and konnyaku balls.

(Prior art) Conventionally, this type of planter has, for example, a planting machine connected to a towing vehicle, and this planting machine is equipped with a hopper for discharging fertilizer on the front side thereof, and a hopper is installed behind the hopper. Some have a structure in which a conveyor is installed on the side to feed agricultural products such as potatoes in order so that they can rotate freely.

The planting machine is then towed by a towing vehicle while straddling the previous crop, such as wheat, to pre-spread fertilizer at the planting location of the crops, and then feed the crops one by one using a conveyor and plant them.

(Problem that the invention aims to solve) With the conventional structure, if the field is on level ground, planting work can be done relatively without problems. Since the machine travels in a direction across the slope, the shared load on each wheel of the towing vehicle and planting machine tends to be biased toward the wheels located on the lower side of the slope, which tends to make straight travel unstable. There is a problem in that crops cannot be planted in a predetermined position, and if the previous crop is adjacent to the previous crop, the previous crop may be trampled by the wheels of the tractor or planting machine.

Furthermore, if the travel distance per stroke is long, depending on the size of the hopper that stores the fertilizer, it may be difficult to secure the amount of fertilizer necessary for at least one stroke of fertilizer spreading. It may be necessary to replenish fertilizers along the way.

Therefore, the present invention was developed in view of the above points, and when traveling in a direction across a slope, the center of gravity of the towing vehicle or planting machine can be moved to the wheel side located on the upper side in the slope direction. This makes it possible to stabilize the straight running of the towing vehicle and planting machine, and ensure that the crops are planted in the designated position. The object of the present invention is to provide a planter that can be prevented from being stepped on by the operator.

(Means for Solving Problems) The present invention provides a planter in which a planting machine 4 is connected to a tractor 1, and crops are fed out and planted one after another while spreading fertilizer. A carrier 12 having a guide rail 13 in the left and right directions with respect to the traveling direction is provided on one of the carriers 12 and a fertilizer bag 27 is placed on the carrier 12 via a guide 25 engaged with the guide rail 13. 26 is provided so as to be movable in the left and right directions with respect to the traveling direction, and when working on a slope, the table 26 is moved and installed from the lower end in the slope direction to the upper part in the slope direction.

(Function) When the field is on a slope, the planter of the present invention moves the platform 26 on the carrier 12 to the guide rail.
