Description

[Detailed description of the invention] This invention prevents the rice transplanter from forgetting to turn on the seedling reduction warning switch during planting work, and reliably warns of the reduction in seedlings during the planting work. This relates to alarm devices.

This invention will be explained below based on embodiments shown in the drawings.

First, the structure of the idea will be explained.

Reference numeral 1 denotes a towing vehicle equipped with front wheels 2 and rear wheels 3, and a rice transplanting device 7 is connected to the rear of a body 4 of this towing vehicle 1 via an upper link 5 and a lower link 6 so as to be able to rise and fall freely. . The rice transplanting device 7 includes a rice transplanting machine body 8 equipped with a transmission device, a planting claw 9, a plurality of seedling tanks 10, 10..., and a float 11.
It is composed of etc.

Reference numeral 12 denotes a center mascot tip that serves as a reference for the towing vehicle 1 to move straight, and the center mascot tip 12 can be used in a used state in which it protrudes above the left and right center portion of the fuselage in front of the seat 13, and in a stored state in which it lies down. Switchably pivoted. In addition, 1
Reference numeral 4 denotes a spring that switches and maintains the center mascot 12 between the operating state and the stored state. 15 is
Line-drawing markers 15 are provided on the left and right sides of the machine body 4, and the line-drawing markers 15 function to form mark grooves on the field that serve as marks for the towing vehicle 1 to move straight during work.

Reference numeral 16 denotes an electric circuit, and an alarm device 17 composed of a lamp or the like is installed in this electric circuit 16 to warn against a decrease in seedlings in the rice transplanting device 7. Detection switches 18, 18, . . . for detecting a decrease in seedlings and a warning switch 19 for warning of a decrease in seedlings are arranged in series. This sensing switch 18 is attached to the lower end of each of the plurality of seedling tanks 10, 10, 10, and when there are seedlings in the seedling tank 10, it rotates downward due to the weight of the seedlings. When a seedling passes through the sensing switch 18, the sensing switch 18 is projected upward from a notch in the seedling tank 10 and rotated, thereby closing the sensing switch 18. In addition, this seedling reduction warning switch 1
9 is disposed near the rotating part of the center mascot tip 12, and as shown in FIG. It is configured so that it comes into contact with the switch 19 and enters the switch-on state. This seedling alarm device 17 is provided so as to be located at the tip of the center mascot 12. Note that this alarm device 17 may be provided on the meter panel 21 near the steering wheel 20 in close proximity to other instruments.

Next, the effect of the invention will be explained. When carrying out rice transplanting work, pine seedlings are loaded into a plurality of seedling tanks 10, 10, . Rice planting work is performed while moving the tractor 1 forward. In this way, when carrying out rice planting work while moving the tow vehicle 1 forward, the rice transplanter is placed in the field on the side of the tow vehicle 1 on the side where no seedlings are planted.
Rotate the line marker 15 downward to ground it,
The planting work is performed while drawing a line along the progress of the towing vehicle 1 on the field scene to be next planted using the tip of the line drawing marker 15. When the towing vehicle 1 performs the planting work by turning back, the center mascot 12 is aligned with the straight line marked with the delineation marker 15 in the previous process, and the towing vehicle 1 is moved while maintaining the regular planting interval. Move it forward and do the planting work.

As described above, when the center mascot tip 12 is projected upward and used for rice planting, the seedling reduction warning switch 19 is closed due to the rotation of the center mascot tip 12, so that the seedling tank is closed. When the number of seedlings 10, 10, etc. decreases and the sensing switch 18 is activated, the alarm device 17 is activated to notify the operator of the decrease in the number of seedlings.
The operator who is thus warned of the decrease in seedlings by the alarm device 17 takes out pine seedlings from the auxiliary seedling frame 22, replenishes them in the seedling tanks 10, 10, and continues rice planting work.

In this invention, a center mast 12, which serves as a reference for straight movement of the towing vehicle 1, is placed at the front right and left center position of the towing vehicle 1 on which the rice transplanting device 7 is attached, and is configured to be switchable between a usage state in which it projects upward and a storage state in which it lies prone. ,
A detection switch 18 for detecting a decrease in seedlings in the seedling tank 10 and a decrease in seedlings warning switch 19 are arranged in series with an electric circuit 16 equipped with an alarm device 17 that warns against a decrease in seedlings in the rice transplanting device 7. This is a seedling reduction warning device for rice transplanting equipment, which is characterized by closing the seedling reduction warning switch 19 when the center mascot 12 is protruded above the center mascot 12, so that the center mascot 12 serves as a progress reference for the machine that is always used during rice planting work. In connection with the switching operation to the upwardly protruding use state, the seedling reduction warning switch 19 can be closed and the electric circuit 16 can be activated, thereby preventing forgetting to turn on the seedling reduction warning switch 19. It is possible to reliably detect the decrease in seedlings during rice planting work.
