[Structure] A spare seedling mounting table 3 capable of feeding a mat seedling A to the lower side of the seedling mounting table 2 above a seedling mounting table 2 which is slanted so as to be reciprocally movable laterally above the seedling removing plate 1. In the rice transplanter constructed by vertically arranging the seedlings, a first sensor 4a and a second sensor 4b capable of detecting the mat seedlings A on the seedling placing table 2 are provided at upper and lower portions of the lower surface of the preliminary seedling placing table 3, respectively. The auxiliary seedling stand 3 is arranged so as to face downward, and the auxiliary seedling stand 3 can be moved downward while operating the solenoid 5 by turning on the second sensor 4b on the lower side.

[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a seedling replenishing device for a rice transplanter, in which a spare seedling placing table installed above the seedling placing table can be effectively moved down so as not to damage the mat seedlings below the seedling placing table and can supplement the seedlings. To do.

[0002]

[Prior Art]

 Conventionally, a preliminary seedling stand that can feed mat seedlings to the lower side of the seedling stand that can be reciprocally moved laterally above the seedling picking plate and can be vertically moved above the seedling stand. In the rice transplanter constructed by erection, the first and second sensors for detecting seedlings are provided at the two upper and lower parts of the bottom surface of the seedling stand, and the second sensor on the lower part turns on to make a backup. The seedling table was moved downward and the mat seedlings on this spare seedling table were supplied to the lower side of the seedling table.

[0003]

[Problems to be solved by the device]

 However, on the lower side of the seedling placing table, part of the mat seedlings above the seedling raising and the movement of the seedling placing table may be lifted up. Therefore, the bottom surface of the mat seedling is separated upward from the second sensor. When the second sensor is turned on, the signal will cause the preliminary seedling placing table to move downwards, destroying or damaging the mat seedlings below, and when seedlings are spliced to the seedling placing table. In addition, the mat seedling was caught in the sensor and blew up, which was a problem.

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such a problem and to preferably implement it with a simple structure. Therefore, mat seedlings on the seedling mounting table are placed above and below the lower surface of the spare seedling mounting table. The first sensor and the second sensor that can be detected are arranged so as to face downward, and the preliminary seedling stand can be moved downward while operating the solenoid by turning on the second sensor on the lower side. .

[0005]

[Action]

 Therefore, if the upper first sensor detects that the mat seedlings have disappeared on the lower side of the seedling placing table, the mat seedlings can be smoothly replenished on the seedling placing table, and the seedling joining of the seedling placing table can be smoothly performed. Even if the mat seedlings that are sufficiently left on the bottom side float up due to the feeding of seedlings or the movement of the seedling mounting table, the second sensor remains in the off state due to the presence of the mat seedlings, and the mat seedlings are scarce. When the rear end of the second sensor is separated from the lower side of the second sensor to the lower side, the second sensor is turned on and the solenoid is operated to move the reserve seedling mounting table downward without any trouble, and The spare seedlings of can be satisfactorily supplied to the lower side of the seedling mounting table.

[0006]

【Example】

 In the planting part of the rice transplanter, two mat seedlings A are placed vertically and reciprocally in the horizontal direction above the seedling take-up plate 1 that can scrape off the block seedlings while passing the planting claws. A movable seedling placing table 2 is installed obliquely, and a spare seedling placing table 3 on which a mat seedling A can be placed is installed above the seedling placing table 2 with its upper end pivotally supported 7 on a bracket 6. The front portion of the spare seedling stand 3 on the open side is made to abut against the support plate 9 supported by the bracket 8, so that the suction rod of the solenoid 5 fixed to the support plate 9 causes the spare seedling stand 3 to come into contact. The first sensor 4a and the second sensor 4b capable of detecting the mat seedlings A on the seedling mounting table 2 are provided at the upper and lower portions of the lower surface of the preliminary seedling mounting table 3 so as to be engaged and disengaged at the front part of the seedling mounting table 3. Each of them is arranged downward, and the solenoid 5 is not operated by turning on the second sensor 4b on the lower side. The preliminary seedling the platform 3 is configured so as to move downward.

Therefore, as shown in FIG. 1, when the mat seedling A is lost on the upper side of the seedling placing table 2, the first sensor 4a detects and gives an alarm, and the mat is placed on the upper side of the seedling placing table 2. Since the seedling A can be smoothly replenished and replenished, even if the mat seedling A that remains in the lower part of the seedling mounting table 2 floats up due to the seedling feeding or the movement of the seedling mounting table 2, The upper second sensor 4b remains in the off state due to the presence of the mat seedling A, and when the mat seedling A becomes less and the rear end portion is separated from below the second sensor 4b to the lower side, the second sensor 4b While the sensor 4b is turned on and the solenoid 5 is operated, the auxiliary seedling stand 3 is moved down without any trouble as shown in FIG. Can be satisfactorily supplied to the lower side.

[0008]

[Effect of the device]

 Thus, according to the present invention, by detecting the upper first sensor 4a, the mat seedling A can be smoothly replenished and replenished on the seedling mounting table 2 without being caught by the sensor of the seedling mounting table as in the conventional type. Therefore, even if the mat seedlings A sufficiently remaining on the lower side of the seedling placing table 2 are lifted up by the feeding of seedlings or the movement of the seedling placing table 2, the second sensor 4b above the mat seedling A The existence of the seedlings keeps the off state and prevents the preliminary seedling stand 3 from dropping onto the mat seedlings A as in the conventional case. When the sensor 4b is separated from the lower side to the lower side, the second sensor 4b is turned on to operate the solenoid 5 to move the auxiliary seedling placing table 3 downward without any trouble. Seedlings on 3 It will be able satisfactorily supplied to the lower side, with a Ru can suitably implement features in the simple structure it is possible to effectively perform the seedling supply of the upper preliminary seedling the platform 3 or al.
