Description

Detailed Description of the Invention (Field of Industrial Application) This invention relates to a device for sowing rice, etc. (including a bed soil supply device, a seeding device, a soil covering device, and a device that performs a combination of these devices). , relates to a device for removing unnecessary materials (soil, rice seeds, and composite materials thereof) on the top surfaces of the front and rear box frames of a seedling box for raising seedlings, which is transported substantially horizontally on one side of the front and back, and a seedling box for raising seedlings that is transported on a rack on the device.

(Prior Art) In conventional seeding work devices, unnecessary materials on the front and rear box frames of a seedling box for raising seedlings to be carried on a rack are fixedly mounted on a plate-shaped device having a width equal to or larger than the left and right width of the seedling box. It was dropped into the inside of the seedling box (sowing surface) using a brush body or a rubber plate.

(Problems to be Solved by the Invention) In the conventional seeding work device described above, unnecessary materials are dropped into the inside of the seedling box for raising seedlings, and only this dropped part is used for sowing work, bed soil supply, and soil covering. This results in a loss of accuracy in each task.

(Means for Solving the Problems) The present invention provides seedlings for raising seedlings that can be transported and moved by a waste removal device that is installed near the height of the top surface of the box frame of a seedling box for raising seedlings that is carried on a top of a transporting device for raising seedlings. The device is characterized in that it is configured to move substantially linearly to the left and right sides of the front and rear box frames of the box.

(Operation) Seedling boxes for raising seedlings are continuously placed on the seedling box conveying device on the starting end side. The seedling box is conveyed approximately horizontally to one side of the front and back by a seedling box conveying device. The seedling box to be transported is continuously subjected to various operations (supply of bed soil, sowing, or supply of cover soil) by a sowing device installed on the seedling box transport device.

The soil and seed rice supplied into the seedling box through this operation are spread over the entire area including the top surface of the box frame of the seedling box.

After passing through these working devices, the seedling box for raising seedlings is further conveyed toward the terminal end of the seedling box conveying device, and reaches the installation location of the waste removal device.

Therefore, a waste removal device that moves in a straight line to one side of the front and rear box frames of the seedling box, which is located near the height of the upper surface of the front and rear box frames of the seedling box and passes under the box frames, is used to raise seedlings. Unwanted materials on the box frames before and after the seedling box are removed and cleaned outside the box.

The removed and cleaned seedling box for raising seedlings is then conveyed toward the terminal end of the seedling box conveying device.

(Example) 1 is a seedling box conveying device, 2 is a sowing device installed above the seedling box conveying device 1, and a feeder installed on a shaft to rotate at the feedout opening of the seed storage hopper 2a of the seeding device 2. Face Roll 2b.

The sowing width of the seeding device 2 is configured to be wider than the inner width of the left and right box frames of the seedling box 3 for raising seedlings.

Near the height of the upper surface of the box frame of the seedling box 3 for raising seedlings, which is transported from the seeding device 2 at the terminal end side in the transporting direction of the seedling box, the waste removal device 4 removes the box frames before and after the seedling box 3 for raising seedlings, which is to be transported. It is configured to move substantially linearly to the left and right sides of 3a and 3b.

An embodiment of the movement of the waste removal device 4 will now be described with reference to the case shown in FIGS. 1 and 2.

5 is the front and rear box frame sides 3 of the seedling box 3 for raising seedlings that can be transported.
The waste removal device 4 is activated at a predetermined timing when the sensor 5 detects the passing position of the box frame sides 3a, 3b. The swing drive device 6 of the waste removal device 4 is activated in response to the sensor 5. A linear reciprocating drive device 7 is connected to the swing drive device 6 . The linear reciprocating device 7 includes a waste removal device 7.
hang.

The movement starting point of the waste removal device 4 is the lower end of the seedling box 3 for raising seedlings that can be transported in FIG. This is done to move from the movement starting point to the state shown in FIG. 2 (the state in which the waste removal device is at the upper end position of the seedling box 3). Thereafter, the waste removal device 4 immediately moves backward and returns to its original position. The oscillating movement speed of the oscillating drive device 6 and the linear movement speed of the linear reciprocating drive device 7 correspond to the conveyance speed adjustment of the seedling box conveying device 1, and the waste removal device 4 moves the boxes before and after the seedling box 3. It is made to move linearly on the frames 3a and 3b.

In the case of the embodiments shown in FIGS. 1 and 2, the waste removal device 4 is of a type that uses a vacuum to suck up waste materials, and 8 is a collection container. As another embodiment of the waste removal device, a scraper type device as shown in FIG. 3 may be used. Further, in the embodiment, a waste removal device 4 is installed at the end of the seedling box conveying direction of the seeding device 2, but the waste removal device 4 is used to remove seedlings from the bed soil supply device or the covering soil supply device. Of course, it may be installed on the terminal end side in the box transport direction, or it may be installed on the terminal end side in the seedling box transport direction of each of the working devices for supplying bed soil, seeding, and covering soil.

(Effects of the Invention) The waste removal device according to the present invention is configured to move substantially straight to the left and right sides of the front and rear box frames of the seedling box for raising seedlings that can be transported and moved. Unwanted materials on the sides of the seedling box for raising seedlings can be removed and cleaned outside the box without falling into the inside of the box, improving the accuracy of various seeding operations.
