Description

Description: TECHNICAL FIELD The present invention relates to a mobile agricultural work machine, and when applying an application material such as seedlings, seeds, and fertilizers to a soil surface while traveling, this application material is used. It is intended to control the traveling speed of this working machine according to the reduced amount of the applied material in the housing device for housing, and it can be used for a seedling planter, a seeder, and the like.

[Conventional technology and its problems]

For example, in a seedling planting machine, when a worker is carrying out seedling transplanting and continues the work by not advancing the machine without knowing that the seedlings supplied to the seedling tank are exhausted, there is no seedling in the seedling tank. Stock status. In order to prevent this, there is a method in which a seedling reduction sensor is provided to stop the aircraft suddenly and the operator replenishes seedlings.

However, in the above method, there is a problem in work safety because the machine suddenly stops, and work efficiency is poor.

[Means for Solving the Problems]

The present invention, in order to solve the problems in the above conventional example,
A working device (3) comprising a storage device (1) for storing an application product such as transplanting, sowing, fertilizing work of a seedling on a soil surface, and an application device (2) for applying the application product of the storage device (1). In a mobile farm work machine in which the traveling vehicle body (6) is mounted, a traveling farm work machine (5) is provided, which detects that the amount of applied material in the storage device (1) has decreased below a predetermined amount and slows the traveling. It was an opportunity.

[Operation of the invention]

When the application device is stored in the storage device (1) and the machine body is advanced to perform a predetermined application by the application device (2), the application product of the storage device (1) is applied to the soil surface by the application device (2). To be done. When the applied material in the storage device (2) is reduced to a predetermined amount or less during work, the traveling speed reducer (5) operates,
The traveling speed of the work device (3) is reduced.

〔The invention's effect〕

As the amount of the applied substance supplied to the storage device (1) is reduced to a predetermined amount or less in this way, the traveling of the machine body is automatically decelerated, so that the operator reduces the amount of the applied substance to the predetermined amount or less. You can safely and reliably recognize what you have done. Further, when the pilot and the assistant are on the work machine, the traveling speed is reduced, so that the assistant can easily replenish the storage device (1) with the applied material and stop the machine body. The work efficiency can be improved because the application work can be continued without it.

A pair of upper and lower lifting links (13) are provided at the rear end of the traveling vehicle body (6) so as to be lifted and lowered by a telescopic cylinder (15) hydraulically interposed between the lifting body and the vehicle body (6). (13) A work equipment (3) is provided with a seedling planting device at the rear end, and this seedling planting device is provided with a seedling tank as a containing device (1) for containing seedlings to be applied, and as a applying device (2). A seedling planting device is installed to separate and plant seedlings supplied from the seedling tank. (16) is a float that can slide on the soil surface while supporting these seedling planting devices.

In each seedling tank, sensors (17) (18) that detect the decrease of seedlings stored in this tank are installed in two places at different distances from the seedling take-out port at the lower end, and the sensors on the upper side (17) is linked with the throttle lever (14), and the sensor (17) detects that the seedling has decreased.
9), and through the solenoid (20), etc., the prime mover (10)
The sensor (18) on the lower side is interlocked with the running clutch petal (39) to detect the decrease of seedlings. This Running Clutch Petal by (39)
Is turned off via a relay (21), a solenoid (22), etc., so that the traveling can be stopped.

In the case of a multi-row planting machine, sensors (17) and (18) are provided for each seedling tank, and a throttle or running clutch is activated each time each sensor (17) or (18) is activated. The configuration is such that they can work together. (23) is the battery, (24)
Is a fuse, (25) is an automatic changeover switch, (26) is a check switch provided between the seedling tank and the machine body (30), which is provided to move the seedling tank laterally with respect to the seedling planting device. When the seedling tank is moved to a fixed position such as the left-right center position or the lateral end position, the seedling tank is turned on. (27) is a reset switch, and (28) and (29) are pilot lamps.

A marker (31) for indicating a distance from an adjacent seedling planting bar is rotatably pivotally attached (32) to a machine body (30) of the work device (3), and a marker (31) is rotated laterally by a spring (33). The marker (31) and the inner wire (34) are provided so that they are in the protruding position (a).
Provide the solenoid (35) to connect to the bracket (36),
The solenoid (35) is provided so that the marker (31) can be moved in and out. This bracket (36)
Is detachably mounted on the piston (37) side of the telescopic cylinder (15) with a hairpin or the like, and when the piston (37) is raised to the upper limit position together with the lifting link (13), the outer wire (38) is pushed. By pulling the inner wire (34), the marker (31) is retracted into the folding position. Also, the marker (31) and solenoid (35)
Is configured such that the solenoid is interlocked with each pair of right and left, and the switches are operated in the vicinity of the steering wheel (7) or the operation of the steering wheel (7).

Adjust the prime mover (10) to a predetermined rotation with the throttle lever (14), engage the running clutch, and run the wheels (8).
When the vehicle travels by the rotation of (9), the working device (3) is pulled together with the traveling vehicle body (6) to proceed, and the seedlings in the seedling tank are separated and planted on the soil surface by the seedling planting device (2). It
