Abstract

PURPOSE:To always uniformly press the surface of a deeply plowed groove and simultaneously form a planting bed while a press wheel invades in the deeply dug and plowed groove by disposing a vertically movable trailing frame having a narrower press wheel than the deeply plowed groove at the rear portion of a deep plowing and digging member in the deep plowing device attached to a tractor. CONSTITUTION:A trailing frame (b) is disposed in a vertically movable state in respect to the supporting shaft 6 of a triangle beam 3 of a deep plowing machine (a) and the vertical height of the deep plowing machine is controlled by a control means comprising a control lever 7 and a guide plate 8. A press wheel 9 having a narrower width than that of the deeply plowed groove is disposed at the rear portion of a pair of longitudinal beams in the trailing frame (b) and right and left hooks and a blanket at the rear end and the central portion, respectively, are disposed. The press wheel 9 partially invades into the deep plowed groove and simultaneously presses the surface layer of the deep plowed groove to form a planting bed. Just after the formation of the planting bed, seeds are sown from a planting machine (c) and rigged up. Since the lateral walls of the groove guides the press wheel, a problem such as the deviation of a sowing position is not caused.

Description

[Detailed description of the invention] [Industrial application field]

This invention relates to an improvement in a method for suppressing excavated trenches of a deep cultivation device attached to a tractor.

[Conventional technology]

In the cultivation of root vegetables, a deep plowing method in which a narrow deep plowing trench is formed and the top of the excavation is pressed to create a planting bed is known, for example, from Japanese Patent Publication No. 56-26361.

[Problems to be solved by the invention]

In the above-mentioned known technology, a wide pressure roll is disposed on the machine body located behind the excavation body, which is wider than the depth of the trench. In the case of this structure, since the traveling body is interposed between the excavation body and the suppression roll, there is a problem that the center of the deep plowing furrow and the center of the roll are inclined or misaligned, and the suppressing effect is uneven. The present invention attempts to form a planting bed at the same time by constantly compressing the surface layer of a deep plowing trench.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides the following features:
To provide a deep plowing device characterized in that a vertically movable traction frame equipped with a suppressing ring narrower than the width of the deep plowing trench is arranged to penetrate into the excavated deep plowing trench and form a planting trench at the same time as suppressing it. There is a particular thing. Furthermore, if a machine for planting seed potatoes or the like is attached to the rear of the above-mentioned towing frame so that its posture can be changed, the work of planting seed potatoes or the like can be completed at the same time.

[For use]

When the deep plowing device of the present invention is introduced into a field and deep plowing work is started, the deep plowing excavation part forms a narrow deep plowing furrow, and the narrow suppressing wheel whose position has been adjusted in advance partially penetrates into the surface layer of the deep plowing furrow. This is to securely suppress the soil while simultaneously forming a planting bed. In addition, a planting machine connected to the rear of the traction frame (with the power to properly follow the posture of the uneven ground in the field) accurately sows seeds on the planting bed mentioned above.

[Example] The configuration will be described based on the drawings in which the present invention is implemented. FIG. 1 is a side view of an embodiment of the present invention, where 1 is a tractor and a is a deep cultivator. The tractor l and deep tiller a are of known technology and are powered by a PTO shaft (not shown). The deep cultivator a is equipped with an endless belt 4 having a digging blade around the outer periphery of a triangular beam 3. The deep cultivator a is lifted up with respect to the tractor using the lifting cylinder 23+. A traction frame b is provided so as to be movable up and down relative to the support shaft No. 6 of the triangular beam 3, and its vertical height is set by a regulating means consisting of a regulating rod 7 and a guide plate 8. C is a planting machine with a frame 11, a case cover 13 and a carrier 14
The plant is driven by a pair of left and right ground wheels. The lO constitutes the front part of the frame body 11 with a three-point hitch, and is attached to the rear end of the traction frame b so that its posture can be changed freely by attaching left and right support shafts and a chain at the top. 18 is a soil plate, and after seed potatoes and the like are sown, it is piled up. Figure 3 is a perspective view of the traction frame b, with a pair of front and rear longitudinal beams 5.
A suppressing ring 9 narrower than the depth of the trench is provided at the rear of the groove, and left and right hooks 20 are provided at the rear end, and a bracket 21 is provided at the center, to which the three-point hitch 10 described above is attached. 22 is a stopper. FIG. 2 shows a state in which the suppressing wheel 9 is partially invading the deep plowing groove 19 while suppressing it. At the same time, the taming remains form a planting bed, and immediately after that, seeds are sown from the planting machine C and the soil is ridged. [Effect] With the above-described structure, at the same time as a deep plowing groove is formed, it penetrates into the surface layer of the groove and provides a constant suppressing effect, and the side walls of the groove act as a guide to maintain straightness. Therefore, even when a planting machine is connected, problems such as misalignment of the sowing position do not occur, and the combined work of accurate deep plowing, compaction, trenching, sowing, and covering soil ridges can be achieved.
