Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sensor for detecting ejected particles of fertilizer, etc. in industrial applications such as fertilizing and seeding machines.

Problems to be Solved by the Invention In a fertilizing/seeding machine that sprays fertilizer, etc. as spray particles into a trench made on the soil surface with a trencher, etc., the fertilizer, etc. is usually transported to the spout via a conveying pipe. Although conveyed by air,
Since this conveyance medium is air, during the conveyance, fertilizer etc. may accumulate in the conveyance pipe and become clogged due to factors such as decreased rotation of the blower that generates the conveyance air or uneven delivery of the fertilizer etc. For this reason, even if the ejected particles are no longer ejected into the groove, it is difficult to detect them because the ejected particles are in the soil.

Means for Solving the Problem This invention provides a fertilization method in which a reflective surface (1) that contacts the ejected particles and reflects them toward the soil surface is used as a sensor for detecting ejected particles that comes into contact with this reflective surface (1).・Configure the ejected particle detection device such as a seeding machine.

Functions and Effects of the Invention In a fertilizing/seeding machine, for example, fertilizer or the like is ejected as ejected particles into a groove made on the soil surface.

At this time, the ejected particles are reflected toward the soil surface by the reflective surface q) to fertilize or sow seeds on the soil surface, and the reflective surface (q)
Since particles that come into contact with the sensor (1) are detected by the sensor (2), it is possible to accurately detect the presence or absence of ejected particles, and since it is of a reflective type, the configuration can be simplified.

Embodiment In the illustrated example, the traveling vehicle body to which the seedling planting device G) is connected is long in the front and rear, and includes a front wheel (6) that is steered by a steering handle 6], and a rear wheel (6) that is shaft-mounted at the rear end of the transmission case. The wheels (8) etc. are provided to be driven in conjunction with a prime mover (9) mounted on the front part, and a hopper 〇[) capable of storing fertilizer etc. is provided near the prime mover (9), and this hopper 〇〇 On the lower side, dispensing devices 0υ for dispensing fertilizer, etc. are arranged at three locations in the front and back, and each dispensing roll inside is provided to rotate appropriately with a shaft (■), and the lower end of each dispensing device 111) The conveyor pipes 0 for conveying fertilizers, etc., which are arranged over almost the front and rear length of the vehicle body (2), are connected to each other midway. The feeding device q
A blower 0 for blowing conveying air to the conveying pipe (2) is provided near D, and this blower (B) and the conveying pipe (2) are communicated and driven in conjunction with each other by the prime mover (9). A pilot seat [F] is provided on the step on the rear upper surface of the transmission case (■).

A seedling planting device (3) is attached to the rear of the driver's seat so that it can be raised and lowered by a link mechanism (JQ), and is interlocked from the traveling vehicle body (4) side. It has a float Q71 that slides on the ground, a seedling tank (G) for storing seedlings on the upper part, and a seedling cutting device (■) for separating and transplanting the seedlings supplied from this seedling tank [F]. Near the front ends of the Q floats, in order to create a groove for ejecting particles to the soil surface, the rear side is inclined so that it can sink into the soil surface, and the rear part is open so that it has a U-shape in plan view. The float O is placed between the front and back of the groove maker (to) which has a heavy structure.
'7) are installed so as to sandwich them, and a spout (2) connected to the terminal end of the conveying pipe (0) is installed at a certain angle in the front part of the groove creator (to), and the water is spouted from the spout (2). A sensor (1) configured with a reflective surface (1) that reflects and ejects the ejected particles toward the soil surface in accordance with the ejecting angle of the ejected particles is attached to the rear part of the trencher (to) the ejection port. ■
Attach it facing the In addition, the rear end of the furrower (f) is linked to the traveling vehicle body from its upper end to the position in contact with the soil surface, and the seedling planting device (link mechanism 11G marked) is moved forward (a). It is moved up and down with respect to the traveling vehicle body (A) by a hydraulic system, and is interlocked to cause the lateral movement of the seedling tank [F] and the seedling action of the seedling planting device (2).

In addition, by sending the wind force generated by the blower 0 into the conveying pipe, the fertilizer etc. fed out from the feeding device (2) is conveyed by air in the form of ejected particles. The ejected particles conveyed by air are ejected from the spout @ at the end of the conveying pipe into the inside of the groove-making device (to), and the reflective surface of the sensor (■) installed opposite to the spout (■) inside the groove-making device (0) (1), and this reflective surface (■) ejects the ejected particles into the groove made on the soil surface, and also checks whether the ejected particles are clogging the conveyor pipe (■) or the spout (■). Detect.

The width of the reflecting surface (1) is made wider than the width of the spout @, and the shape of the reflecting surface (1) is concave as shown in Fig. 2 so that the ejected particles reflected by contact can be concentrated in one direction. It may also be formed.

Also, in order to facilitate inspection, adjustment, and cleaning of the sensor (21) installed in the groove maker, a fulcrum may be provided on the upper side of the sensor, and the sensor may be mounted so as to be rotatable between an active position and a non-active position. In addition, it may be provided in the groove making device (c) as a fitting form so that it can be easily attached and detached.

In addition, in order to prevent the ejected particles that come into contact with the reflective surface (1) of the sensor from scattering when they are reflected and ejected onto the soil surface, there is a Shatter prevention plate■
may be provided integrally with the sensor (2).

In addition, when covering the ejected particles ejected into the grooves on the soil surface, a reflective surface (D) is used to cover the soil covering plates from the lower end of D toward the soil surface so that the soil can be covered consistently depending on the depth of the groove. sensor(
It may also be provided integrally with 2.
