Description

DETAILED DESCRIPTION OF THE INVENTION The present invention can be installed, for example, in a furrower for fertilization and direct sowing operations, to detect clogging of agricultural powder and granular materials such as fertilizers and sowing, and to ensure good fertilization and direct sowing operations. In order to be used as a clogging sensor, the present invention is applied to a powder clogging detection device of an agricultural working machine, which is used as a clogging sensor.

As this type of detection device, there is a conventionally known one described in Mononotes VC Utility Model Application Publication No. 111854-158708'j+. This device is equipped with a switch that is a sensor for detecting clogging in the supply flow path and at the lower end of the discharge pipe that supplies powder and granules, and an alarm is issued based on the clogging detection result of this switch. The system is equipped with an alarm that emits alarms. Therefore, if the switch is in the supply flow path
Since the switch is located at a lower position, the cross section of the supply channel is substantially reduced, and there is a risk that the switch itself becomes an obstacle to the flowing powder and granules, causing a blockage.

On the other hand, as a means to solve the above-mentioned problems, there is a sound sensor system that detects the sound generated by the powder flowing down the supply flow path without turning the switch inside the supply flow path, Although it is possible to adopt a capacitance type sensor, these devices are disadvantageous in terms of cost since the mechanism becomes complicated and equipment costs increase.

In view of the above circumstances, the present invention aims to solve the problems of the conventional structure by effectively arranging the sensing body with respect to the supply flow path, and to provide a means for solving the problem without incurring a significant increase in cost. have a purpose.

The characteristic configuration of the powder clogging detection device for an agricultural working machine according to the present invention, which has been made to achieve the above object, is that a sensing body that is driven to advance intermittently is provided in a flow path for supplying agricultural powder and granules; The present invention is configured to electrically detect an increase in the advancing resistance of the sensing body.

The effects of the present invention having such a characteristic configuration are as follows.

In other words, as a method for detecting clogging, a method is adopted that electrically captures the operating resistance that the sensing element receives depending on the amount of clogging.Since it is a mechanical type, it is possible to reduce equipment costs, and the above-mentioned sensing Since the body advances into the supply channel intermittently, it is possible to eliminate the problem that the sensing body reduces the cross section of the channel or becomes an obstacle to the flow of the powder or granular material. Furthermore, in order to increase the sensitivity of the sensing body, the sensor does not have to be configured to operate more easily than necessary, which is likely to cause malfunctions due to vibrations, and stable operation can be performed over a very long period of time.

Embodiments of the present invention will be described below based on the drawings.
