[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a crushing and seeding control device for a seeding plant.

[0002]

[Prior art]

 Conventionally, as one form of a sowing plant, a seedling growing pot configured by arranging a large number of cells vertically and horizontally is placed on a tray and transported along a transport path while filling and leveling the soil in the cells. By operating the pressure suppressor and the seeding device based on the cell detection outputs from the microswitches provided for the pressure suppressor and the seeding device in the transport path, the recess for seeding the soil in the cell is formed. There was a seeding plant in which cells were automatically seeded by forming seeds, seeding in the same recesses, and covering with soil.

Further, there are several kinds of seedling-growing pots whose outer dimensions are constant, but the number of cells is changed according to the kind of seedlings to be grown, and these several kinds of seedling-growing pots can be treated in the above plant.

[0004]

[Problems to be solved by the device]

 However, when the seedling raising pot type is changed, the size of the seedling raising pot is constant, but the cell arrangement pitch differs depending on the type, and the cell detection position and the suppression position or the seeding position are different. Since the distance and the transportation time during this period are different, it is necessary to change and adjust the arrangement position of the microswitch according to the arrangement pitch every time the seedling raising pot is changed, as shown in FIG.

[0005]

[Means for Solving the Problems]

 In the present invention, while transporting a seedling growing pot configured by arranging a large number of cells vertically and horizontally, a recess for seeding is formed in the soil filled in the cells with a pressure suppressor, and seeding is carried out in the recess. Equipped with a cell sensor for pressure suppression and seeding, which detects the cells being transported, which is installed in the transportation device, and a control device with a timer function. By delaying the set time correspondingly to activate the pressure suppressor and the seeding device and making it possible to change the setting of the delay time, it is possible to suppress and seed seedling pots of different cell numbers. The present invention is intended to provide a planting pressure suppression and seeding control device characterized by the above.

FIG. 11 shows another embodiment in which the delay time setting dial D is replaced with push buttons B1 to B4 corresponding to the contacts D1 to D4.

Then, the programmable controller PC operates in the following procedure to perform sowing work.

That is, as shown in FIG. 12, when power is connected to the sowing plant A and the start / stop button SB is pressed (70), each device of the sowing plant A becomes operable (71). When the transport device 1 is activated (72) and the programmable controller PC is reset (73) at the same time, the programmable controller PC then starts the pressure suppression program P1 and the pressure suppression cell sensor S1 detects and outputs the cell S. (74) When the counter function counts the above outputs (75) and the count reaches 2 (76), the timer function causes the delay time setting dial D to contact for only the time set by one of the contacts D1 to D4. After delaying (77), the air is output to the air control valve 54 of the pressure suppressor 5 (78), the pressure suppressor 52 is moved downward to form the seeding recess, the counter and timer are reset (79), and the pressure suppressing cell sensor is used. Waiting for input from S1 Return (80).

When the seeding program is started in parallel with the execution of the pressure suppression program, and the seeding cell sensor S2 detects and outputs the cell S (90), the output is counted by the counter function. When the count number becomes 2 (92) (92), the timer function delays the time set by any of the contacts D1 to D4 of the delay time setting dial D (93), and the seeding device 6 (94), the seeding operation is performed, the counter and timer are reset (95), and the state of waiting for input from the seeding cell sensor S2 is returned (96).

The memory areas for the counter function and the timer function are separately set for the pressure suppression and the seeding, and both of the counter functions output with two inputs, but the timer function does not. Each of them is set to fit the above-mentioned several kinds of seedling raising pots P.

In this way, the crushing operation and the sowing operation are delayed by the time set according to the number of the cells S of the seedling raising pot P after the cell sensors S1 and S2 respectively detect the cells S twice. By operating in this manner, it is possible to accurately form the seeding concave portion at a predetermined position of the cell S and accurately seed the concave portion.

When changing the type of the seedling raising pot P, it is only necessary to operate the delay time setting dial D and select a suitable contact from the contacts D1 to D4.

The embodiment of the present invention is configured as described above, and the tray T on which the seedling raising pot P is set is placed on the tray placing portion 9 at the start end of the transport device 1, and the soil filling device 2 and the soil cover are placed. The soil is supplied to the hoppers 14 and 43 of the device 7, the water is supplied to the irrigation devices 4 and 8, and the seed is supplied to the seed hopper 61 of the seeding device 6, respectively, and the start / stop button SB of the operation panel 19 of the controller C is supplied. Is operated to start the transport device 1 to sequentially deliver and transport the tray T at a constant speed.

Then, the seedling-raising pot P is filled with the seedling-raising pot P in the soil-feeding device 2, the surface is leveled by the leveling device 3, a predetermined amount of water is irrigated by the irrigation device 4, and the seedling-growing device 5 is used for raising seedlings. A recess for seeding was formed on the surface of the leveled soil filled in each cell S of the pot P, a predetermined number of seeds were seeded in the recess by the seeding device 6, and seeded by the soil covering device 7. The seeds are covered with soil and irrigated with the irrigation device 8 to complete the sowing work.

The seeding operation is automatically performed under the control of the control device C. In particular, in the pressure suppression work by the pressure suppressor 5, the cells S of the moving seedling raising pot P are used for pressure suppression. From the time when the cell sensor S1 detects twice, the pressure suppressor 52 is lowered after a set time for each type of the seedling raising pot P, but the cell S moves together with the seedling raising pot P at a constant speed. In addition, since the distance between the crushing cell sensor S1 and the crusher 52 is constant, the crusher 52 accurately forms the seeding recess at the same position of each cell S.

The seeding device 6 also performs seeding with a delay from the time when the seeding cell sensor S2 detects the cell S twice, for a time set for each kind of the seedling-growing pot P, and the same as above. Moreover, the seeding can be accurately seeded in the seed recess.

By operating the delay time setting dial D according to the type of the seedling raising pot P, various seedling raising pots P can be dealt with, and troublesome work such as adjusting the sensor mounting position is not required.

As described above, since the adjustment work accompanying the change of the seedling raising pot P is not required, the operation of the sowing plant A is facilitated, and further, the trouble due to the mistake of the adjustment work can be prevented. There is.

It should be noted that, so far, the case where the pressure suppressor and the seeding mouth each have two rows has been described, but the number of rows of the pressure suppressor and the seeding mouth is not limited to the above two rows, and the number of counts for each row is counted. The same effect as described above can be obtained only by matching
