Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for forming ridges in agriculture and a ridge making machine.

(Conventional technology) In recent years, greenhouse cultivation of strawberries, melons, etc. has become popular, and ridge forming machines that use small management machines are used to create ridges in the limited field area inside greenhouses. It will be done.

For example, the method of forming ridges using a conventional ridge-making machine is an external pile-up method.First, the field is tilled with a tiller wheel, the tilled soil is thrown up to the side with a flip-up blade, and the ridges are heaped up. A pair of soil pressing plates in the shape of a rock are opened and closed to compress and compact the cultivated soil to form a ridge with an inclined slope.

(Problem B to be Solved by the Invention) By the way, there are the following problems in the ridge forming method using the conventional ridge forming machine.

In other words, this kind of house is a standard product and has a width of 5400m.
m or 5,600 mm, and in order to make the most effective use of this width and maximize the yield, the width of the ridge must be 400 an as shown in Figure 8.
However, in the conventional ridge forming method using a ridge making machine, the ridge width is 40011I11,
When a slope with a predetermined inclination angle for holding the ridges is formed, the ridge grooves become narrow to 150 mm to 20 mm, making it difficult for workers to walk and work.

The present invention provides a method for forming a ridge that widens the ridge groove without changing the width of the ridge, making it easier for a worker to perform tasks such as harvesting, and furthermore, provides a method for forming a ridge that enables the formation of the ridge. The purpose is to provide a machine.

(Means for Solving the Problems) In order to achieve the above object, the ridge forming method of the present invention involves tilling a field approximately vertically downward in a constant width with a rotationally driven tilling wheel, and then using a method in which the upper part is ridged. By opening and closing a pair of earthen plates that are inclined along the surface and whose lower part extends out to the side,
The gist is to make the lower part of the ridge dig inward.

Further, the ridge forming machine of the present invention for carrying out this method of forming ridges includes a rotationally driven tiller and a rear part thereof.
In a device that has a pair of left and right soil pressing plates that make a dynamic movement when opening and closing to heap up cultivated soil and press it against the ridges to form a slope.
A special feature of the earthen board is that the upper part of the earthen board is inclined along the slope of the ridge, and the lower part is formed to extend out to the side.

(Function) To form a ridge, first, a tilling wheel equipped with flip-up blades of a predetermined width is rotatably driven to till the field, thereby forming a tilled surface cut approximately vertically downward with a predetermined width. Then, the plowed and dug up soil is flipped up with a flip-up blade to heave up the ridges. Next, the soil is compacted by hitting the opponent's slope by opening and closing a pair of earth pressing plates located at the rear, and the upper part of the earth pressing plate slopes along the slope of the ridge. At the same time, the lower part of the ridge is formed so as to extend out to the side, so when the lower part is opened and closed, the lower part of the ridge can be dug inward by this overhanging part.This allows the ridge to be formed without changing the width of the ridge. It becomes possible to widen the width of the groove and widen the passage.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 7. This ridged Ml is an external ridge, has an engine 1a mounted on the frame F as a drive source, is provided with a handle 1b that the worker operates while walking, and is further provided with a pair of running wheels that are rotationally driven by the engine 1a. Wheels 2 are installed. A tilling wheel 3 is provided at the bottom of the cough frame F. This is a reduction gear 7 with a plurality of flip-up blades 5 attached to a rotary shaft extending left and right from the shaft 4, and is rotationally driven by transmitting the rotational force of the engine 1a. Further, a pair of left and right soil pressing plates 6 are provided on the frame F behind the tilling wheel 3. The upper pusher VI6 consisted of a front part and a side part, the side part was arranged in an upwardly opening manner, the lower end was pivotally supported on the frame F as a rotation fulcrum 7, and the upper part was connected to the output shaft of the engine la. It is connected to the operating rod 8 to provide an opening/closing swing motion.

The shape of the side surface of the upper pusher Vi6 is such that the upper part is inclined along the slope of the ridge, and the lower part is partially extended toward the ridge side (outside in the figure) to form an overhanging part 9.

The width of the projecting portions 9 on both sides when the soil pushing plate 6 is expanded is set to be the tilling width of the tilling wheel 3 and the distance between the roads. In addition, the code|symbol 10 is a front board provided in the front surface of the earth pressing board 6.

The ridge forming work ′ by the ridge forming machine 1 configured in this way is as follows:
First, as shown in FIG. 3, the field is tilled by making a substantially vertical downward cut with the width of the flip-up blade 5 of the tilling wheel 3, and the tilled soil is heaped up into ridges on the sides by the action of the flip-up blade 5. Next, as shown in FIG. 4, the rear soil pushing plate 6 is opened and closed one movement to compact the cultivated soil piled up in the ridges. At this time, the lower overhanging part 9 can compact the cultivated soil at the lower part of the ridge to the tilled surface tilled by the tilling wheel 3.
The width of the ridge can be widened by digging the bottom of the ridge into the inside of the ridge. As a result, in the above-described house, the width of the ridges can be changed from 150 to 200 mm to 250 to 300 mm. In addition, since the cultivated soil at the bottom of the ridge is pounded and compacted by the overhanging portion 9 in this way, the bottom of the ridge can be compacted well, which is effective in preventing ridge collapse.

Note that there is also an embodiment in which the above embodiment is modified as follows. First, as shown in FIG. 5, the projecting portion 9 formed at the lower part of the earth pressing plate 6 may be formed over the entire lower part of the earth pressing plate 6. In addition, in the above embodiment, the lower part of the earth pressing plate 6 was pivotally supported and the operating rod 8 was connected to the upper part, but conversely, the upper part was used as a rotation fulcrum and the operating rod 8 was connected to the lower part. year,
Alternatively, there is no problem in using a structure in which the earth pressing plate 6 is opened and closed as a whole by using a known link mechanism as appropriate, or the earth pressing plate 6 can be divided into front and rear halves as shown in FIG. 6. , the front half 6a is fixed, a projecting part 9 is formed at the bottom of the rear half 6b, this rear half 6b is rotatably attached to the front half 6a by a hinge, etc., and an operating rod is connected to this so that it can be moved laterally. It may also be configured to swing open and close. Furthermore, as shown in FIG. 7, instead of the above-mentioned outer mound 2, an inner mound type is used in which the tilled soil is piled up inside by raking, and an overhanging part 9 is formed at the lower part of the soil pressing plate 6 toward the ridge side. It's okay.

(Effects of the Invention) As detailed above, the method for forming ridges of the present invention uses a ridge making machine that has an overhanging part extending toward the ridge side at the bottom of a soil pressing plate, and uses this to form a ridge. By compacting the cultivated soil, the lower part of the ridge can be pushed into the inside of the ridge, making it possible to widen the width of the ridge without changing the width of the ridge.This allows the floor area of the ridge to be made sufficient within the greenhouse. While taking a wide range of
The width of the passage can be widened to make harvesting and other operations easier.
