Next, the backward forced rise control of the seedling planting device A will be described with reference to the flow chart shown in FIG. H
When the ST lever 19 is operated to the reverse position, the seedling planting apparatus A automatically rises to the set height position (maximum lift position) and stops (# 1, # 2, # 3, # 6). In this case, although not shown, the following control mode was used. In other words, when the seedling planting device A is being forcibly raised in the reverse drive state, HS
When the T-lever 19 is operated to the forward side, the seedling planting device A stops at that time. Therefore, in order to lower the seedling planting apparatus A, it is necessary to operate the forced elevating lever 42 to lower it. If you have such a configuration,
For example, in order to correct the position a little when turning around at the edge of the road and entering into the adjacency or the like, there is a case in which the seedling planting apparatus A is once moved to the forward side before the seedling planting apparatus A is fully raised,
In order to lower the seedling planting apparatus A, the forced lift lever 42 must be operated. In that case, it is necessary to change the holding of the lever and the like, and the quick operability is lacking.
Therefore, the following control configuration is adopted. That is, if the seedling planting apparatus A is in the ascending state in the reverse state and the state is switched to the forward state, the seedling planting apparatus A automatically descends. Even if the seedling planting apparatus A is stopped at a position lower than the maximum position that rises when moving backward, when the seedling planting apparatus A is switched to the forward state, the seedling planting apparatus A automatically descends (# 4, #
5, # 7). This enables the descending operation of the seedling planting device A without changing the lever. As such lowering control, the seedling planting apparatus A may be automatically lowered when the HST lever 19 is moved forward within a certain short time from the time when the backward movement is performed. The operation position of the HST lever 19 is detected by the potentiometer 46 provided at the base end, and the detection device receives the detection signal by the control device 43 as a control means to control the elevating valve 47 to control the seedling planting device A. Lift control. The raising / lowering operation of the seedling planting device A by the forced raising / lowering lever 42 functions only when the raising / lowering lever 10 is operated to the automatic position. Planting clutch 4
1 can be turned on and off by operating the elevating lever 10 to the planting position, but can also be performed by operating the forced elevating lever 42 downward twice.

Next, the fertilizer application device B will be described. FIG.
As shown in FIG. 4, the fertilizer application device B applied to 8-row planting will be described.
Each tank 48 has a pair of left and right feeding mechanisms 4
9. A downflow hose 50 and a grooving device 51 are provided for side fertilization. Of the two grooving devices 51 corresponding to the central two rows, the grooving device 51 located on the left side is vertically dividable. This is related to the configuration of the leveling float 18 in which one in the center and two in the left and right are arranged as shown in FIG. It is this central float 1 that you need one in the center
This is because 8A also serves as a grounding sensor and is essential for lifting control. Then, when the seedling planting device A is switched to the retracted posture, the central float 18A needs to belong to one of the left and right seedling planting device portions AL and AR, and as illustrated, the right seedling planting device portion AR. Belong to. By the way, as shown in FIG. 13, the grooving device 51 attached to the left side surface of the central float 18 includes a granular material storage tank 48, a feeding mechanism 49, and a downflow hose 50 belonging to the left seedling planting device section AL. It is connected to the connected system. In other words, it is necessary to provide a dividable part in a part of the system from the tank 48 to the grooving device 51, and as a means for realizing this, a structure in which the grooving device 51 is divided into upper and lower parts is adopted. Therefore, when it is stored in FIG.
As shown in, the lower working groove device 51B of the upper and lower working groove devices 51A and 51B is removed from the upper working groove device 51A. When the grooving tool 51 is configured to be separable as described above, it may be forgotten to attach the removed lower grooving tool 51B when the storage posture is returned to the working posture, and fertilization work may not be successful. There is. Therefore, as shown in FIG. 15, the continuity sensor 52 is formed across the upper and lower groove makers 51A and 51B to configure a detection unit that detects whether or not the two 51A and 51B are connected. The detecting means 52 may be a limit switch. As a result, even when the work posture is restored, if the upper and lower groovers 51A and 51B are not connected, the alarm device 53 is operated through the control device 43 as a control means. Whether or not the work posture is returned is determined by providing a continuity sensor on the lock tool D or by using a contact sensor such as a limit switch for detecting the return to the work posture or a non-contact type sensor such as an optical type. Provide and try to do it. As the alarm device 53, a buzzer type device that appeals to the hearing or a device that visually appeals such as blinking a lamp may be adopted.
