Description

[Detailed Description of the Invention] The present invention relates to a seedling feeding device for a seedling stand in a rice transplanter.

In other words, in a rice transplanter that has a sensor installed protrudingly in the middle of a seedling stand to detect when it is time to replenish pine seedlings and to detect problems, conventionally, the sensor has been used to detect when the next supply of pine seedlings has arrived. Or,
The slippage on the sensor was poor and the sensor was not able to operate reliably.

The present invention solves these shortcomings, and provides a simple structure that allows pine seedlings to easily climb over the sensor, ensures that the sensor works well, and allows suitable implementation. It is.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the rice transplanter. Drive wheels 4, 4 are mounted on both sides of the float 3, and an engine 5 is mounted above the front of the float 3.
A transmission case 6 extending rearward above the float 3
A planting depth adjustment lever 7 is interposed between the rear of the drive case 6 and the rear of the float 3, a handle 8 is extended from the rear of the transmission case 6 to the upper rear, and a seedling carrier A is installed in front of the handle 8 so as to be able to carry two mat seedlings B, and is reciprocally mounted in the lateral direction.
The planter is configured in the same manner as the conventional structure, with two cutouts 11 formed on both sides to enable seedlings to be removed, and two-row planting is possible.

Seedling loading surfaces a, a are formed on the left and right sides of the seedling loading platform A, respectively, so that pine seedlings B can be placed and sent to the seedling takeout table 9 side, and the seedling loading surfaces a are approached at the lower part of the tip side of both seedling loading surfaces a. A plurality of star foils 12 for forcibly feeding the pine seedlings B intermittently are arranged side by side in the part where the pine seedlings B are fed, and a hole 13 is formed in the part of the seedling mounting surface a slightly above the star foils 12. The hole 13 is equipped with a sensor 1 whose upper surface protrudes upward by being pressed by a bullet 14, and when the pine seedling B is on the sensor 1, the sensor 1 is centered around its upper end and its lower end When the side lowers and the pine seedling B leaves the sensor 1, the sensor 1 operates so that its lower end side moves upward and is linked to the switch 15, and the pine seedling B leaves the sensor 1 and enters the supply state. When a trouble occurs, the switch 15 is configured to activate an alarm and notify the operator.

In addition, a plurality of holes 16 are arranged horizontally and bored in the part of the seedling mounting surface a on the upper side of the slope approaching the sensor 1, and metal holes 17 are formed below the seedling mounting surface a.
A plurality of circular roller-shaped rotating bodies 2 whose surfaces in contact with pine seedlings are flat are freely rotatably mounted on a shaft rod 18 which is mounted on a shaft 18, and the upper part of each rotating body 2 is attached to a seedling mounting surface a.
The holes 1 are arranged so that they protrude slightly upward.
6. Install and configure as shown in Figure 6.

In the figure, 19 is a support rod for pine seedling B.
Therefore, during the work, pine seedlings B are placed on both seedling mounting surfaces a of the seedling mounting table A, and the star foil 12 forcibly feeds the pine seedlings B to the seedling take-out table 9 side intermittently for planting. The block seedlings are planted on the rice field while being scraped by the claws 10, but when the pine seedlings B slide down on the sensor 1, they are not in a state to replenish the pine seedlings, and the lower end of the sensor 1 is attached to the pine seedlings B.
This causes the alarm to be pushed downward and the alarm will not activate.

As shown in FIG. 4, when there are few remaining pine seedlings B and they move away from the sensor 1, the lower end of the sensor 1 is moved upward by the bullet 14 to activate the alarm and notify the operator. New pine seedlings B are replenished onto the seedling surface a.

In that case, the front part of the supplied pine seedling B rides on each rotating body 2 and slides down to the sensor 1 as shown by the imaginary line in FIG.
The pine seedling B climbs onto the sensor 1, presses down on the lower end of the sensor 1, and slides down to connect with the rear of the previous pine seedling B. The rotating body 2 lifts the pine seedling B a little and feeds it onto the sensor 1, so the sensor This eliminates the problem of pine seedling B being stuck on sensor 1 or slipping on sensor 1.

As described above, the present invention provides a rice transplanter in which a sensor for detecting replenishment timing and troubles of pine seedlings is installed protrudingly in the middle of a seedling stand, and the sensor is installed at the upper end and the lower end of the rice transplanter. The side is installed on the seedling loading surface of the seedling loading stand so that it can move up and down, and the seedling loading stand is provided with a contact surface with pine seedlings in the middle of the upper side of the seedling loading stand in the vicinity of the sensor. The pine seedlings are flat, and an appropriate number of rotating bodies that are able to feed the pine seedlings on top of them are installed in a slightly protruding shape above the seedling table surface so that they can rotate freely. The pine seedlings that are to be supplied next can be directly hit by the protruding sensor, unlike conventional methods, because the pine seedlings to be supplied next can be directly hit by the protruding sensor. In addition, since the sensor is installed so that it can move up and down on the seedling surface of the seedling stand, with the upper end centered on the sensor, the lower end of the sensor is This allows the pine seedlings to smoothly exit below the surface on which the pine seedlings are placed, sufficiently preventing the pine seedlings from slipping on the sensor, allowing the sensor to operate reliably and properly. Since the contact surface with the seedlings is flat and rotatable, it is possible to feed pine seedlings smoothly and with little resistance. The larger the amount, the more reliable the detection, but on the other hand,
It has an excellent feature that can solve the drawback of the seedling stand sensor that the supplied pine seedlings are easily caught.

Claims (1)

[Scope of utility model registration request] In a rice transplanter that has a sensor installed protrudingly in the middle of a seedling stand, which detects when to replenish pine seedlings and detects trouble, the sensor is mounted on the seedling stand so that its lower end can move up and down with the upper end of the sensor at the center. It is installed on the seedling mounting surface so as to be able to move in and out of the seedling mounting surface, and the surface in contact with the pine seedlings is flat in the middle part of the seedling mounting table, which is on the upper side of the slope of the seedling mounting surface near the sensor. This seedling feeding device for a seedling table is characterized in that a suitable number of rotating bodies, which can be run on and fed, are installed in a slightly protruding manner above the surface of the seedling table so as to be freely rotatable.
