BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of submerged direct sowing machines, and more particularly to an apparatus for detecting missing seed grains.

[0002]

2. Description of the Related Art In a conventional direct sowing machine, a seed grain missing sensor is attached to a lower end of a hose of a seed grain supply section. There was space. That is, the supply hose was not directly connected to the groove body.

[0003]

In the above-mentioned conventional flooded direct sowing machine, a sensor for missing seed grains is mounted at a lower end of a supply hose, and this portion is formed with a groove. Because there is a space between the body and the open state, water may enter this part during work,
Coating seed clogging was likely to occur. The present invention has been devised in order to solve such a problem. The purpose of the invention is to shut off the missing particle sensor from water, and to supply a seed grain supply side hose and a float side. The purpose is to make the connection with the grooved body flexible.

[0004]

In order to achieve the above object, in the present invention, water is prevented from entering between the hose on the supply side of the seed grains and the groove on the float side. In addition to the connection, the problem is solved by providing a missing particle sensor in this portion. That is, the present invention
The hose on the fixed-quantity supply side of seed grains and the grooved body attached to the float are connected by a boot formed of an elastic member, and the seed grains flowing down from the hose on the delivery side to this boot are connected. It has a configuration in which a missing particle sensor for detecting missing particles is detachably provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an outline of a submerged direct sowing machine (A).
This is connected to a traveling machine (not shown) by a link (1). Submerged direct sowing machine (A)
There is a fixed amount feeding section (b) directly below a hopper (a) for storing seed grains, and a bellows-like supply hose (c) is provided below the hopper (a), and a grooved body attached to the float (d). (E) is connected by a boot (g) having a particle missing sensor (f). As shown in FIG. 2, the groove forming body (e) is bent in an inverted L-shape, the groove forming part (2) has a boat shape, and the direct seeding part (3) following the groove forming part (2) is cylindrical. Has made. The connection side of the boot (g) to the supply hose (c) forms a bellows-like mounting portion (4), and the boot (g) is externally fitted to the supply hose (c) at this portion, and continues to this mounting portion (4). The central part (5) is formed obliquely in the lower right direction, and the lower connecting part (6) following this part (5) fits externally to the direct seeding part (3) of the groove forming body (e). doing. In the center part (5), a chipping sensor (f) is detachably inserted from the same side as the grooved part (2) of the grooved body (e) toward the lower right direction. And the inner end surface (7) of the missing particle sensor (f) is located at the center (5) of the foots (g).
It is parallel to the inner wall surface. Therefore, seed grains flowing down from the supply hose (c) through the bellows-like connecting portion (4) fall on the inclined inner end surface (7) of the missing sensor (f).

[0006] To explain the operation, the seed grains are stored in the hopper (a), and the seed grains are supplied in a bellows-like manner through a fixed amount feeding section (b) by driving from the traveling machine side by traveling. The hose (c) flows down, passes through the boot (g), and flows down from the direct sowing machine (3) of the groove forming body (e). On the other hand, a groove for a seed is formed in the mud at the groove portion (2) of the groove body (e) by traveling on the traveling machine side. Therefore, the seed grains stored in the hopper (a) flow down by a fixed amount to the grooves formed by the groove forming body (e) by the running of the flooded direct sowing machine (A) by the traveling machine, and the groove forming bodies are formed. Seeding is performed through the direct sowing part (3) of (e).
In such a seeding operation, when seed grains in the hopper (a) are lost or the seed grains do not flow down for other reasons, the missing grain sensor (f) provided in the boot (g) is used. It detects that the seed grains do not flow down and issues an alarm (not shown). The boot (g) provided with the above-described particle missing sensor (f) can be similarly used for a side-row fertilizer. FIG. 3 is a front view of a case where a side-strip fertilizer (B) is provided in addition to a submerged direct sowing machine (A).
(G ') is a boot and (f') is a sensor.

[0007]

[Effects of the Invention] The present invention connects a fixed amount feeding hose of seed grains and a grooved body attached to a float with a boot formed of an elastic member, and a method of forming seed grains flowing down to the boot. Since the chipping sensor that detects chipping is detachably provided, there is a space between the chipping sensor provided at the lower end of the supply hose and the lower groove, as in the past, so that it is open. Unlike some, the sensor surface of the missing particle sensor is always protected by boots, so that this part does not get wet by infiltration water and therefore does not clog, especially in the case of coated seeds etc. Absent. Further, since the boot can be removed from the supply hose and the groove, the maintenance of those parts where mud is easily attached can be easily performed. Further, since the boot is formed of an elastic member, the boot is flexible in connecting the supply hose on the fixed-rate feeding section side and the groove forming body on the float side, and does not hinder the connection.
