Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ridge side-shaving device that is applied to an agricultural vehicle, such as a ridge-cutting machine, equipped with a driven tiller wheel.

(Prior Art) Generally, a ridge-making machine is used for ridge-making work in fields, fields, etc. For example, this device is basically equipped with a tilling wheel consisting of a large number of flip-up blades on a running vehicle, but recently, a pair of soil pushing plates installed at the rear of the wheel have been used. The wheels dig up the soil and push the cultivated soil to the sides of the machine, creating ridges, while a pair of soil pressing plates located behind it compresses and compacts the cultivated soil to form the ridges.

(Problem that the invention aims to solve) By the way, when forming ridges, the above operation is usually repeated several times to form gradually taller ridges, but the width that can be tilled with a tilling wheel is not constant. Because of this, as the ridges become taller as they progress through the first and second steps, the sides of the ridges become steep, making it difficult to heave cultivated soil into the ridges even with the action of the flip-up blades.

In addition, the above-mentioned ridge making machine compresses and compacts the sides of the ridge with a clay plate after each operation, so the side surfaces of the ridge are in a smooth state, and in the next process, the surface is further improved. Even if an attempt was made to mound and compact the soil, the cultivated soil would not adhere to the soil and would fall off.

Therefore, the purpose of the present invention is to provide a ridge side shaving device that can scrape the sides of the ridge into a desired shape at the same time as the ridge forming process, in order to solve the above-mentioned problems during the intermediate to final ridge forming process. This is what I did.

(Means for Solving the Problems) The ridge side shaving device of the present invention which achieves the above object consists of a pair of left and right side shaving blades provided in front of the tilling wheel, and the side shaving blades have a substantially inverted V-shape. , and is characterized by being connected to an operating rod that swings the side scraping blade approximately back and forth with respect to the direction of travel of the vehicle.

(Function) In the intermediate or final process of ridge-making work, a pair of left and right side-shaving blades set in an approximately inverted V-shape are provided in front of the tilling wheel of the ridge-making machine, and while swinging in the front-rear direction, Work is done using a ridge machine. When this happens, the side shaving blade shaves off the side surface of the ridge diagonally, leaving the ridge in an almost inverted V-shape that opens upwards.
It also scrapes away the smooth surface layer that has been compacted by the earth pressing plate.

(Example) An example of the present invention will be described below with reference to the drawings.

Side cutting blades 9, 9 are attached to the left and right side frames 10b, 10b, which are set in a substantially inverted V-shape. Attach the bent part into a dogleg shape to the side frame 10b with screws 1
5 and is installed with the blade surface expanded toward the front. Next, a mechanism for swinging the side cutting blades 9, 9 attached to the machine frame 10 will be explained.

The frame F is provided with an output drive shaft 16 drawn out from the drive system of the engine 1a, and a crank 19 is attached to a reduction shaft 18 that is connected to the drive shaft 16 through a chain 17 and is driven to reduce speed. The tip of the conrod 20 extending forward from the crank 19 is attached to a support shaft 2 provided on the frame F.
It is connected to one end of a drive lever 22 with 1 as a fulcrum and a self-aligning joint 23. on the other hand,
An operating rod 24 is rotatably connected to the other end of the drive lever 22 by a mounting pin 25 so as to be substantially perpendicular thereto, and the tip of the operating rod 24 is connected to the upper horizontal frame 10a of the machine frame 10 by a mounting pin 26. They are rotatably connected.

With such a mechanism, as shown in FIG.
It is connected to the vehicle and swings approximately in the longitudinal direction with respect to the direction of travel of the vehicle.

Although the illustrated embodiment shows a case where the upper part is swung with the lower part as a fulcrum, the mechanism for swinging back and forth is not limited to this, and for example, the mechanism shown in FIG. It is also possible to change the system to a method in which the operating rods 27 are connected to the upper and lower positions of the frame 10, and the entire side surface scraping blade 9 is swung back and forth. Further, the spacing between the side surface scraping blades 9, 9 is adjusted according to the shape of the ridge, etc., and the one shown in FIG.

This embodiment is configured as described above,
The operation will be explained with reference to FIGS. 2 and 8.
In order to complete the ridges, the ridge making process using the ridge making machine is repeated at least twice.In the first step, the soil is dug up by the tilling wheel 3, the tilled soil is thrown up to the side of the machine, and the soil is pushed up by the soil pushing plate. This is used to compact and compact the cultivated soil. As a result, shallow ridges shown at A in FIG. 8 are formed. Incidentally, in order to make the ridges higher, the above operation is repeated several times.

Therefore, the ridge side shaving device operates in the intermediate process to the final process of ridge formation, and this device is attached to a deceleration shaft 18 connected to a drive shaft 16 that interlocks with the tilling wheel 3 and the soil pushing plate 6. A reciprocating motion is imparted to the connecting rod 20 by the crank 19, which swings the drive lever 22 at its end, causing a reciprocating motion in the operating rod 24, which
a to cause the machine frame 10, whose lower portion is pivotally supported, to undergo a rocking motion.

This rocking motion of the machine frame 10 causes a pair of left and right side scraping blades 9, 9, which are set in a substantially inverted V-shape, to rock back and forth. Therefore, when the ridge making machine runs between the furrows, the front side scraping blade 9 cuts up the side surface of the ridge or the side surface portion of the ridge that has been compressed by the soil pressing plate 6 (the eighth The soil (indicated by C in the figure) is shaved off, the sides are shaped into an upward-opening shape, and the hard compacted surface layer is removed to reveal the normal soil surface, which is then dug up by the tiller wheel 3. The soil is thrown up and then pressed down by the soil pressing plate 6 to complete the ridge shown at B in the figure.

(Effects) As described above, the present invention has a pair of left and right side scraping blades provided in front of the tilling wheel in an approximately inverted V-shape, and connects an operating rod that swings the blades to scrape the sides of the ridge. Because it is shaved off, the sides of the ridge can be shaped into the desired upward-opening shape during ridge work.
In addition, since the side shaving blade is actively driven, the ridge forming machine can perform the ridge forming operation smoothly without any problems such as slipping due to resistance.

And as a result, even if the height of the ridge is high,
The cultivated soil can be thrown up into the ridges and piled up, and furthermore, the raised tilled soil can be effectively attached to the sides of the ridges to create ridges that do not cause the ridges to collapse.

Although this embodiment shows the case where it is applied to a type of ridge making machine equipped with a soil pushing plate behind the tilling wheel, the device to which the ridge side scraping device can be applied is not limited to this. However, it can be applied to various types of equipment as long as they are equipped with at least a tilling wheel.
