Description

[Detailed Description of the Invention] The present invention relates to a seedling mat abnormality warning device in a rice transplanter.

By arranging a plurality of star foils in parallel, the vertical feeding mechanism for transferring the mat seedlings on the seedling platform in the vertical feeding direction toward the seedling take-out port can be configured to freely reciprocate in a direction perpendicular to the vertical feeding direction. In a rice transplanter equipped with a seedling platform, we detect various defects in the seedling mat, such as poor slippage, broken seedlings, and collapsed seedlings. A detector is placed between the star foils directly above the star foils, and is protruded from the top of the seedling stand so that it can be pushed up and in contact with the bottom of the seedling mat. Accurately detects the situation and notifies the situation using the alarm lamp on the center marker.The center marker, which the operator always sees, makes it easy to see and confirm the supply status of mat seedlings, ensuring smooth rice planting work. It is something to do.

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

Figure 1 shows a side view of a riding rice transplanter.The machine has four wheels 1 on the front, rear, left and right sides.A handle 2 and a seat 3 are installed at the top of the machine, and an engine is installed at the rear of the machine. To run away.

In addition, in front of both front wheels 1, there are three wheels spaced apart in the lateral direction.
Two planting claws 7, which are driven by a transmission part, are arranged rearward on both sides of each float 5, so that six rows can be planted. is arranged with six seedling stands A tilted forward, and the seedling take-out openings 8 at the front of the lower end of each seedling stand A are arranged so that the planting claws 7 are respectively exposed, and the seedling stands approaching the seedling taking-out openings 8 are A plurality of star foils 10 are arranged in parallel on the lower surface part a of the stand A as a vertical feeding mechanism for transporting the mat seedlings 9 in the fir feeding direction toward the seedling outlet 8, and each seedling loading stand is arranged perpendicularly to the vertical feeding direction. It is configured to be able to freely reciprocate in the direction.

Reference numeral 11 denotes a center marker, which is fixed to the support frame 12 above the float 5, protrudes toward the front of the aircraft at an appropriate interval, and has its tip bent upward so that the operator sitting on the seat 3 can use it as a seedling stand. An alarm lamp B in the form of a miniature light bulb is attached as a visual alarm mechanism to the upper refraction part of the center marker 11 which can be seen through above A.

A small hole 13 is formed in the lower surface a portion of the seedling stand A that approaches the star foil 10, and a detection body C that projects slightly upward through the hole 13 comes into contact with the lower surface of the mat seedling 9. As the mat seedlings 9 are fed vertically, the support rod is configured to be able to move vertically and forcibly move to the opposite side, and supports a detection body C that can move vertically in this manner at one end. The central part of the support rod 14 is pivotally connected to a fulcrum O below the lower surface of the seedling stand A, and an operating rod 15 is connected to the other end of the support rod 14, so that the operating rod 15 can swing in the vertical direction. There is.

Further, a magnet 16 is fixed to the operating rod 15, and a proximity switch S is fixed below the lower surface a of the seedling stand A that approaches the magnet 16. The magnet 16 is connected to the proximity switch S when the operating rod 15 is forcibly pushed downward to move the detection object C upward.
When the detection object C is moved downward, the operating rod 15 is moved upward, and the magnet 16 is activated by the proximity switch S. The switch is turned off and the alarm lamp B is turned off when the user moves away from the user.

Below the upper part of the seedling stand A is a horizontal support stand 1.
9 is fixed to the body, and left and right cams 20 . Seedling stand A with 20' attached and reciprocating movement
has moved to one end and the planting claw 7 is positioned at the lower end of the seedling platform A, and the other has moved the seedling platform A to the other end and the planting claw 7 has reached the lower end of the seedling platform A.
is facing the other lower end of the seedling stand A, and the tip of the actuating rod 15 is connected to the cam 20. 20' and is forcibly pushed downward, and both cams 20'
．． 20', the operating rod 15 remains in an upwardly movable state.

Therefore, in the rice planting work, the mat seedlings 9 placed on the lower surface a of the seedling platform A are vertically fed down one step at a time by each star foil 10, and the seedlings are planted by the horizontal reciprocating movement of the seedling platform A. The attached claw 7 scrapes the seedlings from the seedling take-out port 8 and plants the seedlings.

In that case, when the seedling stand A moves laterally, the detection object C is placed on the mat seedling 9, as shown in FIGS. 2 to 5.
The actuating rod 15 is engaged with the lower surface of the actuator and moves downward, and the operating rod 15 is moved upward, and the magnet 16 is separated from the proximity switch S, and the warning lamp B is turned off.

When the reciprocating sliding seedling stand A moves to one end, the sixth
As shown in the figure, the operating rod 15 in contact with the cam 20 is forcibly pushed down, the magnet 16 approaches the proximity switch S, the switch is turned on, and the alarm lamp B lights up.At the same time, the mat seedling 9 The detection body C that is in contact with the lower surface of the detection body C is in a state of being moved upward in the contact state.

From this state, the operating rod 15 separates from the cam 20, and the mat seedling 9 is vertically fed upward by the star foil 10, and the detection body C that engages with the lower surface of the vertically fed mat seedling 9 is pulled. The actuating rod 15 is accordingly moved upward, and the magnet 16 is separated from the proximity switch S, causing the alarm lamp B to go out.

Further, even when the seedling stand A is moved to the other end side, as shown in FIG. 7, it operates in the same manner as described above.

Therefore, when the seedling supply is performed normally, the warning lamp B turns on once and then goes out immediately after operating as described above, and while sitting in seat 3 and constantly looking at the center marker 11, The operator who controls and controls the progress of the vehicle can easily monitor its status.

By the way, when the mat seedlings 9 on the seedling platform A become slippery or disappear, the operating rod 15 is forcibly moved downward and the detection body C is forcibly moved upward by the cams 20 and 20'. , the detection object C is not moved downward by the mat seedling 9, and the magnet 16
remains close to proximity switch S, and alarm lamp B lights up.
The lamp will remain lit, allowing the operator to immediately make adjustments or replenish seedlings.

In addition, by pointing the center marker 11 toward the front of the aircraft and projecting it at an appropriate distance, the distance between the center marker 11 and the driving reference can be reduced, making it easy to check whether the two are in good or bad condition, improving the steering accuracy of the aircraft. can do.

In this case, since the distance between the worker's position and the center marker 11 position becomes large, it tends to be difficult to confirm the lighting status of the alarm lamp B provided on the center marker 11. However, in this embodiment, Center marker 11
Since the warning lamp is installed in the upper bending section, the warning lamp B faces the worker in close proximity, making it easy to check the lighting status of the warning lamp B, and also makes it easier to use when working under clear skies. Even in such a case, it is possible to easily confirm that the warning lamp B is turned on without taking measures such as increasing the illuminance of the warning lamp B.

In this way, the present invention constructs a vertical feeding mechanism that transports the mat seedlings on the seedling table in the vertical feeding direction toward the seedling take-out port by arranging a plurality of star foils in parallel, and also provides a vertical feeding mechanism that is perpendicular to the vertical feeding direction. In a rice transplanter equipped with a seedling platform configured to freely reciprocate in the direction, a detection object for detecting defects in the seedling mat placed on the seedling platform is placed directly above the star foil. At the same time, a visual alarm mechanism that is activated based on the detection result of the detection object is installed at the front of the rice transplanter. Since the center marker is provided at the upper bent part of the center marker, which is formed by protruding at appropriate intervals and bending its tip upward, it is possible to more accurately detect defects in the state of placing the seedling mat on the seedling table. Based on the detection result of the detected object, an alarm mechanism installed in the center marker can be activated to notify the operator of the malfunction without delay. Since it is attached, it can be easily monitored at all times, and the supply status of mat seedlings can be confirmed without fail, and the rice planting work can be carried out reliably and smoothly.

Furthermore, a visual alarm mechanism that is activated based on the detection result of the detection object is provided in the upper bending part of the center marker, which projects in front of the rice transplanter at an appropriate interval and has its tip bent upward. Both the verification state of the center marker and the driving reference and the alarm state of the alarm mechanism, which are contradictory to each other, can be easily and accurately performed without complicating the alarm mechanism.

Furthermore, the position of the detection object is placed directly above the star foil,
We are trying to accurately detect any defects in the placed state of the seedling mat near the vertical feed mechanism, but since the position is further specified between the star foils, the vertical feed action of the star foils will cause the star foil to Even if the bottom surface of the seedling mat in contact with the seedling mat is pushed up in a concave shape, the placement state of the seedling mat can be accurately detected without being affected by this.
