Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a root vegetable digging device that can easily pull out root vegetables such as radish and burdock that extend deep into the soil even though it is long.

[0002]

[Prior art]

 Conventionally, for example, long digging has been performed by digging the soil on the long side with a trencher, and then digging the long soil by breaking the soil by hand.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional method, it is necessary to bring the trencher close to the row for a long time.Therefore, there is a problem that the trencher that is approached is likely to be scratched for a long time, resulting in a low yield rate of the dug product. There is also a problem that the manual work of digging while breaking the soil is difficult, and in the case of cultivating sand in sand dunes, the blade of the trencher is extremely susceptible to wear.

In view of the above-mentioned conventional circumstances, the present invention has been devised to solve the problem, in which compressed air is jetted at the same time as grooving by the grooving body. The purpose of the present invention is to provide a root vegetable digging device capable of easily removing the root vegetables by breaking down the soil and maintaining good soil removal.

[0005]

[Means for solving the problem]

 The present invention that achieves the above-mentioned object is provided with a grooving body for grooving while advancing in the front-back direction while vibrating in the front-back direction along one side of the root vegetable row that extends deep into the soil, or both left and right sides that sandwich the root vegetable row. The cutting body is provided with a spouting section that spouts pressured air toward the root vegetables.

[0006]

[Operation] Therefore, the groove M of a predetermined depth is formed by the grooved body 19 which is oscillating in the anteroposterior direction along one side of the root vegetables row that extends deep into the soil, or on both the left and right sides sandwiching the root vegetables row. At the same time as the formation, pressure air is ejected from the grooved body 19 located in the groove M toward the root vegetables, so that one side of the root vegetables row, or both the left and right sides of the root vegetables row, is located around the root vegetables. The soil is finely crushed through many cracks in the soil, and the root hairs are in a state where the root hairs can be easily pulled away from the soil.

Further, since it is not necessary to dig close to the root vegetables row as in the case of digging with a conventional trencher, the root vegetables are less damaged and the yield of the dug products is improved. Further, in sandy cultivation, even if the cutting blade 20 provided in front of the grooving body 19 in the advancing direction is worn, the grooving body 19 itself moves while vibrating, so that the original grooving function is not significantly deteriorated. .

[0008] Furthermore, since air is forcibly supplied into the soil when digging root vegetables, oxygen is supplied to the soil to improve the soil, and compressed air is blown out to remove soil adhered to the root vegetables. To be done.

【Example】

 Hereinafter, the drawings showing the present invention as an embodiment will be described. As shown in FIG. 1, the excavator H is attached to the rear of an unillustrated agricultural tractor or the like via a three-point link mechanism consisting of a top link and a lower link, and a gear case 2 is attached to the center of the machine frame 1. The pinion shaft 3 that is attached to the gear case 2 and extends forward from the gear case 2 is driven by the PTO shaft by being connected to the PTO shaft at the rear of the agricultural tractor via a connecting shaft (not shown). A pump 5 fixed to the machine frame 1 is driven by a connecting shaft 4 extending further rearward from the gear case 2. Further, eccentric cams 7 are fixed to the left and right connecting shafts 6 and 6 extending from the gear case 2 to the left and right, respectively, and a fulcrum shaft 9 supported by the machine frame 1 is located behind each eccentric cam 7. The vibrating bodies 10 that can vibrate in the front-back direction are respectively provided. At the tip of a front arm 11 extending forward from the vibrating body 10, an idler roller 12 contacting an eccentric cam 7 is rotatably supported, and an upper arm 13 extending upwardly from the vibrating body 10 and a machine. Between the upper part of the support rod 14 erected on the frame 1 and the upper part of the supporting rod 14, a return spring 15 is interlocked and connected by a connecting rod 16, and the vibrating body 10 is always returned by the return spring 15 to the eccentric cam 7 side. Is pressed towards.

The upper part of the grooved body 19 extending deeply into the soil is bolted to the connecting portion 17 extending below the vibrating body 11. The grooved body 19 is located at the front position in the traveling direction. A cutting blade 20 for cutting soil is provided, and a lower portion of the cutting blade 20 is provided in a slanted shape so as to be more forward than the upper portion in the traveling direction. Further, a vertical beak 21 composed of a pipe along the rear side is fixed to the rear side of the grooved body 19, the beak 21 is closed at the bottom, and three ejection holes 22 are provided across the longitudinal direction. At the same time, by connecting the upper part thereof to the air tank 23 and the pump 5 via a discharge pipe 25 which will be described later, the grooving body 19 deeply extends into the soil to form a jet portion for jetting pressurized air toward the long N. It is configured. As shown in FIG. 4, the ejection holes 22 provided in the beak 21 are directed inside and obliquely rearward of the grooved bodies 19 arranged on both left and right sides, and the grooved bodies 19 are soil-like. Therefore, it is possible to provide only one on one side.

The air tank 23 fixed to one side of the machine casing 1 is connected to the discharge side of the pump 5 via a connecting pipe 24 provided on the lower side, and a pair of left and right discharges provided on the upper side thereof. The pipes 25, 25 are connected to the upper portions of the respective beaks 21 located on the left and right. By providing an automatic intermittent opening / closing valve or the like at the outlet communicating with each discharge pipe 25 of the air tank 23, it is possible to intermittently eject the pressurized air from the ejection holes 22. By intermittently ejecting pressured air in this way, it is longer to intermittently apply pressure to the sand, but the sand around N tends to collapse, and the high-pressure air can be ejected instantaneously easily. Although it is long, there is an advantage that the sand around N can be more easily broken. When the grooved body 19 is provided on only one side, the discharge pipe 25 communicating with one beak 21 is closed.

Therefore, by driving the pinion shaft 3 from the PTO shaft, the left and right connecting shafts 6 and the connecting shaft 4 extending rearward are respectively rotated, whereby the eccentric cam 7 and the pump 5 are rotated. . When the eccentric cam 7 rotates, the grooved body 19 oscillates back and forth about the fulcrum shaft 9, while the compressed air generated by the rotation of the pump 5 enters the air tank 23 through the connecting pipe 24. It is stored. At the same time, the agricultural tractor pulls the excavating device H and moves to the front side, so as shown in FIG. 4, it oscillates to the left and right sides of the long N cultivation row that extends deep into the soil. A groove M having a predetermined depth is formed by the left and right groove-cutting bodies 19, and when the groove-cutting body 19 passes through the N position although it is long, it is compressed diagonally inward from a plurality of ejection holes 22 provided in the beak 21. Since the air is ejected intermittently, the soil is finely crushed through many cracks that occur in the soil around the long N, and the long N can easily pull out the root hairs from the soil.

[0013]

[Effect of device]

 As described above, according to the present invention, a groove having a predetermined depth is formed on one side of a row of root vegetables extending in the soil, or on both left and right sides of the row of root vegetables by a grooved body that advances while vibrating in the front-back direction. At the same time that it can be formed, pressure air is ejected from the grooved body located in this groove toward the root vegetables, so one side of the root vegetable row or both left and right sides sandwiching the root vegetable row are generated in the soil around the root vegetable. The soil is finely crushed through numerous cracks, and the root hair of root vegetables can be easily pulled away from the soil.

Moreover, since it is not necessary to dig close to the root vegetables row as in the case of digging with a conventional trencher, the root vegetables are less damaged, the yield rate of the digging products can be improved, and in the sandy cultivation. Even if the front portion of the grooving body in the traveling direction is worn, the grooving body itself oscillates in the front-back direction, so that the original deterioration of the grooving function can be reduced. Furthermore, since air is forcibly supplied into the soil when the root vegetables are dug out, oxygen is supplied to the soil and the soil is improved, and at the same time, compressed air is ejected to remove soil adhering to the root vegetables. To be done.

Therefore, since the soil around the root vegetables collapses and the soil separation becomes good, the root vegetables can be easily pulled out.
