Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a ground work machine in which one of multiple types of ground work machines with different number of rows is connected to a traveling machine of common specifications. relates to an improvement in an electrical signal system from a sensor provided for each piece of ground work equipment.

[Conventional technology]

Considering a riding-type rice transplanter as an example of ground-based work equipment, for example, in a model with a number of planting rows of 4 to 8 rows, compared to a traveling machine with a common specification, a rice transplanter with a different number of rows can be planted. Rice transplanters are often constructed by connecting attached devices;
- Like the one shown in Publication No. 59816, a sensor is provided for each row of the seedling planting device to detect seedling breakage, and a display that allows the operator to detect seedling breakage by inputting signals from these sensors. Some devices have the device mounted on the traveling aircraft.

[Problem that the invention attempts to solve]

In addition, in order to operate the display device as described above, the number of signal wiring from the sensor that detects seedling breakage is required to be at least the same number as the number of ground work devices, so Of these,
It is conceivable to increase the versatility of the traveling body by providing the traveling body with signal wiring that can accommodate a number of sensors equal to the maximum number of lines.

In addition, at the manufacturing stage of the rice transplanter, if different work is required depending on the number of rows of the seedling planting device, such as when attaching a line marker to the traveling device to which the seedling planting device is not connected, the device may be attached to the traveling device. A means is required to confirm the number of rows of the seedling planting device connected to the plant.

The purpose of this invention is to create a configuration that can grasp the number of ground work devices connected to the traveling aircraft by making reasonable improvements and utilizing the high versatility of the signal system provided in the traveling aircraft. It's in the point of gaining.

[Means for solving problems]

The feature of the present invention is that, in the ground work machine having the above configuration, a group of switches for opening and closing circuits of a number equal to the maximum number of lines of the ground work devices is provided on the traveling machine body, and each line of the ground work device is connected to A signal system is formed for inputting the circuit from the installed sensor to the control means provided in the traveling body via the switch group, and its operation and effects are as follows.

[Effect]

When the above characteristics are configured as shown in FIGS. 1 and 2, for example, the operating pieces 18a of the switch group 18 are turned on for a number of times equal to the number of rows of the seedling planting device A connected to the traveling body 1. By operating, for example, when the seedling planting device A is removed during the manufacturing stage of the rice transplanter or during repair, the operation piece 18a...
By simply checking the number of devices that have been turned on, the number of seedling planting devices A connected to the traveling machine 1 can be determined.

[Effect of idea]

Therefore, by making a relatively simple improvement by adding a group of switches to the signal system provided in the traveling aircraft,
A configuration was obtained in which the number of ground work devices connected to the traveling aircraft could be determined.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 4, a 4-row seedling planting device A is connected to the rear of the traveling body 1 so that it can be raised and lowered by the operation of a hydraulic cylinder 2, as an example of a ground working device. It consists of a riding-type rice transplanter.

As shown in the same figure and FIG. Four planting arms 5 for cutting out seedlings one by one, and three soil leveling floats 6...
The four seedling placement surfaces 4a of the seedling placement stand 4...
A sensor S for detecting a decrease in the amount of remaining seedlings is attached to each of them.

The rice transplanter also has a request for replenishment of pine-shaped seedlings W when the sensor S detects that the seedlings have run out, and a request for replenishing the seedling planting device A when the traveling body 1 is turned on a headland. It is equipped with a notification device that issues a request for a descent operation in human language.

That is, the notification device includes the four sensors S..., the limit switches 7, 7, which detect the operation of the left and right handbrakes B, which are operated when the traveling aircraft 1 turns, and the seedling planting device A, which are set to the raised position. The control device 9 is an example of a control means to which signals from the sensors S, etc. are input, a sound generation circuit 10, and a speaker 11. 1
If it detects that the seedlings are out at any time, it will request the seedlings to be replenished using the words "please replenish the seedlings." Also, if it detects that one of the handbrakes has been operated, the seedlings will be refilled at the same time. When it is detected through the limit switches 7, 7, and 8 that the attachment device A is in the raised position, a lowering operation is requested in human words, ``Please lower the planting device.''

The handbrake is a device that independently brakes the left and right rear wheels 12, 12 provided on the traveling aircraft 1, and as shown in FIG. 14, 14, and the limit switch 7 is operated by an abutment piece 15a formed on a bracket 15 which fits onto the rod 14 so as to be adjustable in position.

Further, the traveling body 1 is configured to be able to connect a seedling planting device for 4 or more rows up to 8 rows, and even when a seedling planting device for 8 rows is connected, the above-mentioned notification device can be operated. The input signal system is configured as shown below.

That is, as shown in FIGS. 1 and 2, the board 16 to which signals from the sensors S are inputted is provided with a connector 17 for eight circuits, and the signals of eight circuits from this connector 17 are provided. A dip-type switch group 18 for opening and closing the path is provided, and the switch group 18 is opened/closed (ON/OFF) by sliding operations of eight operating pieces 18a.

For example, when the seedling planting device A is removed for repair, the number of rows of the seedling planting device A can be determined from the operation position of the operating pieces 18a.

[Another example]

In addition to the above-mentioned embodiments, the present invention may also include, for example, the ground work device may be a seeding machine or a fertilizer application machine, and
The vehicle may be operated by an agricultural tractor.
