Description

[Detailed description of the invention] The present invention relates to an alarm device for an agricultural membrane coating device, and is designed to ensure that the operator is informed when there is no agricultural membrane in the membrane supply section. be.

In so-called mulching work, in which the ridges are covered with an agricultural membrane such as a sheet or film, the ridges are formed by a ridge former at the rear of the tiller, and the agricultural membrane fed from the membrane supply unit is trampled by a membrane treader. Agricultural membrane coating equipment is used, which allows the membrane to be coated at the same time as the ridges are formed.

However, when agricultural membranes run out during work and there are no more membranes in the membrane supply section, workers often do not notice this and continue their work, hindering the smooth progress of the work. .

The present invention solves the above problems, and its features include a ridge former located at the rear of the tillage device, a membrane supply unit that supplies agricultural membranes to the ridges, and an agricultural membrane supply unit that supplies agricultural membranes to the ridges. In an agricultural membrane covering device comprising a membrane treading body that presses the membrane against soil, an alarm is provided in the membrane supply section that is activated when a detection switch detects that the agricultural membrane is running out. At the point.

Hereinafter, the present invention will be explained according to the illustrated embodiments.
In the figures and FIG. 2, reference numeral 1 denotes a tilling device, which is towed behind a tractor via a three-point link 2.

The tilling device 1 includes a tilling section 3 which is driven by receiving power from a PTO shaft of a tractor, and the tilling section 3 works to till the soil and to appropriately crush the soil and bring it to the center.

Reference numeral 4 denotes a support rod, which is pivotally attached to the machine frame 5 of the tilling device 1 and extends rearward, and a tool bar 6 is horizontally suspended behind the support rod 4.

Reference numeral 7 denotes a ridge shaper attached to the tool bar 6 via a bracket 8 or the like, which is disposed at the rear central part of the tillage device 1 and shapes the tilled soil into an iron shape.

Reference numeral 9 denotes a pair of left and right gauge wheels arranged on both sides of the ridge former 7, which are attached to the tool bar 6 via a gauge support member 10.

Reference numeral 11 denotes a membrane supply unit, which is equipped with a roll 14 supported by a pair of left and right roll supports 12 so as to be perpendicular to the ridges 13, and an agricultural membrane made of a film or sheet is mounted on the roll 14. 15 is wound so as to be freely drawn out toward the ridge 13.

The roll support 12 is provided to project rearward from the gauge support member 10.

Reference numeral 18 denotes a mounting rod that projects rearward from the center of the tool bar 6 in the longitudinal direction.

Reference numeral 17 denotes a front guide member, which extends from the front end of the mounting rod 16 to the lower center of the membrane supply section 11, and has an arch-shaped first guide section 17a at the rear and lower part of the membrane supply section 11. Be prepared.

Reference numeral 18 denotes a rear guide member, which is attached in a hanging manner to the rear end of the soffit 16, and has a second guide part located behind the first guide part 17a, which has an arch shape that straddles the ridge 13 on the lower end side. 18
Equipped with a.

The guide members 17 and 18 are for guiding the membrane body 15 fed out from the membrane body supply section 11, and the membrane body 15 is connected to the first guide section 17.
It passes through the upper side of the second guide part 18a and is guided in the backward downward direction along the lower side of the second guide part 18a.

Reference numeral 19 denotes a pair of left and right protruding rods that are provided rearwardly on the tool bar 6. At the rear end of the protruding rod 19, a pair of left and right membrane stepping bodies 2 are provided.
0 and a pair of left and right soil covering members 21 located behind it are attached.

Reference numeral 22 denotes a detection switch attached to the rear guide member 18, and its actuation piece 22a protrudes so as to come into contact between the first guide part 17a and the second guide part 18a of the membrane body 15. When the membrane body 15 is in contact, the detection switch 22 is opened by the pressing force, and when the membrane body 15 is no longer in contact, the detection switch 22 is closed.

This detection switch 22 is connected to the alarm buzzer 2 as shown in FIG.
3. It is connected to a battery 25 mounted on the tractor via the main switch 24 of the tractor.

Note that the warning buzzer 23 is installed near the seat of the tractor.

According to the configuration of the above embodiment, when the main switch 24 is turned on and the tractor is driven, the tilling device 1 and the ridge former 7 are turned on.
A ridge 13 is formed in the soil by the function of 1
3 to press both ends of the covered agricultural membrane body 15 against the soil.

At this time, the operating piece 22a of the detection switch 22 comes into contact with the membrane 15, and since the detection switch 22 is open, the alarm buzzer 23 does not operate.

However, when the agricultural membrane 15 is used up during the work and runs out, the membrane 15 no longer contacts the operating piece 22a, the detection switch 22 closes, and the alarm buzzer 23 operates to issue an alarm.

Therefore, the operator can reliably know that the membrane body 15 has disappeared from the membrane body supply section 11, and there is no risk of making a mistake such as continuing the work without noticing that the membrane body 15 has disappeared. can proceed smoothly.

In the above embodiment, the detection switch 22 detects that the membrane body 15 is missing between the first guide part 17a and the second guide part 18a, but instead of this, the membrane body supply part 11 is The presence or absence of the membrane 15 may be detected, or the absence of the membrane 15 between the second guide portion 18a and the membrane treading body 20 may be detected.

Further, other alarm devices such as an alarm lamp may be provided in place of or together with the alarm buzzer 23.

Furthermore, a manual switch may be provided in place of the main switch 24.

According to the present invention, the membrane supply section is provided with a detection switch that detects when the agricultural membrane has run out, and an alarm that is activated when the detection switch is detected. will issue an alarm and the worker will be able to know for sure that the agricultural membrane is gone, eliminating the risk of them not noticing this and continuing their work.
Work can proceed smoothly.

In addition, there is no need to constantly worry about the presence or absence of agricultural membranes as in the past, and the work can be carried out with peace of mind.
