Description

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

In other words, in a rice transplanter in which a seedling loading stand is installed so as to be able to reciprocate in the horizontal direction relative to a seedling take-out stand into which the planting claws are exposed, conventionally, the seedling feeder for vertically feeding the mat seedlings is provided with links, cams, etc. However, there were problems with slipping, the structure was complicated, and there were problems with durability and noise.

The present invention solves this problem, and provides a simple structure that allows vertical feeding of mat seedlings in a reliable and good manner and can be carried out suitably.

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

Fig. 1 shows a plan view of the rice transplanter, in which an engine E is mounted above the front part of a float 6, and two axles 8, 8 are attached to the tips of both transmission cases 7 and 7 installed on both sides of the rear of the engine E. A handle 10 is extended rearward from the rear of the planting case 9 extending to the rear of the aircraft, and a planting depth adjustment lever is installed between the rear of the planting case 9 and the rear of the float 6. 11, and a side-shaped seedling takeout table 2 having notches 12, 12 through which both planting claws 1, 1 can be seen is installed horizontally, and 2 mats are placed horizontally so that two mat seedlings can be placed thereon. The lower part of the seedling loading stand A, which is partitioned into a plane and tilted, is installed so that it can reciprocate in the lateral direction along the seedling taking out stand 2, and is constructed in the same manner as the conventional type.

Three longitudinally long through holes 13 are formed in the lower surface 3 on the lower side of the seedling stand A, and the middle part of the arm 5 located below each through hole 13 is fixed at the tip of a support arm 14. A seedling feeding rook 4 that extends into the through hole 13 and projects slightly above the lower surface 3 is mounted on the upper part of each support arm 14 via a pin 15. When moving from the upper side of the slope of the hole 13 to the lower side, the arm 5 does not rotate and becomes locked, and conversely, when moving from the lower side to the upper side, the arm 5
A clutch body 16 is interposed between the shaft of the seedling feeding rook 4 and the tip of the arm 5 so that the seedling feeding rook 4 can rotate freely.

A tension spring 18 is connected between the pin 17 at the lower end of the arm 5 below the pin 15 and the tip of the protrusion 14a at the lower side of the support arm 14, and a bracket is attached to the lower part of the seedling stand A. The pin 17 is connected to the tip of a suction rod 20 which moves in and out from a solenoid B fixed via a solenoid B via a connecting rod 21.

Cams 23a and 23b are formed at both ends of the horizontal support 22 fixedly installed at the bottom of the seedling stand A, and the machine frame 24 below the cams 23a and 23b are welded and turned on. A switch S is installed, but when the seedling stand A moves fully in the lateral direction, one of the cams 23a and 23b comes into contact with the switch S, and the switch S activates the solenoid B to attract the suction rod 20. Install and configure it as follows.

When the mat seedlings are placed on the lower surface 3 of the seedling platform A, the upper part of each seedling feeding rook 4 engages with the bottom surface of the mat seedlings in the state shown in FIGS. 3 and 4. The lower end surface approaches the seedling take-out stand 2 side, and as the seedling stand A moves laterally from this state, the planting claws 1 extend into the notches 12 and remove the mat. The seedlings are scraped off and planted on the field below.

In this way, when the seedling platform 2 moves to the end in the lateral direction and the bottom row of the mat seedlings is scraped off by the planting claws 1, the sixth
As shown in the figure, when one cam 23b comes into contact with the switch S and the switch S is turned on, the solenoid B is activated.When the waist suction rod 20 is attracted, the tension spring 18 is tensed and the arm 5 is centered on the pin 15. While rotating, the seedling feeding rook 4 moves forward as shown by arrow A. On the other hand, due to the interposition of the clutch body 16, the rook 4 does not rotate and engages with the mat seedlings to move the mat. The seedlings will be sent vertically downward.

After that, when the seedling stand A starts to move laterally in the opposite direction, the cam 23b moves away from the switch S and the excitation of the solenoid B is released, and the tension force of the tension spring 18 causes the seedling feeding rook 4 to move in the opposite direction. On the other hand, the clutch body 16 allows the rook 4 to freely rotate without catching the mat seedlings.

Similarly, when the seedling stand A moves to the other end in the lateral direction and the other cam 23a contacts the switch S, the mat seedlings are fed in the same manner as described above.

In this way, the present invention provides a rice transplanter in which a seedling tray is installed to be able to reciprocate in the lateral direction relative to a seedling take-out table into which the planting claws are exposed. A seedling feeder that engages with the bottom surface is installed on a lower arm, and a solenoid connected to the arm is installed so that the seedling feeder can be reciprocated in the vertical direction of the seedling platform, so that Tsuremade is activated. Then, the mat seedlings can be vertically fed by the seedling feeder while rotating the arm, and the solenoid allows for reliable vertical feeding, which solves the conventional problems mentioned above and is suitable for its simple structure. It has the advantage of being able to be implemented in many ways.
