Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a device for digging up long root vegetables, and more specifically, to a device for digging up long root vegetables so as not to disturb the posture during harvesting.

[Conventional technology]

When harvesting long root vegetables such as Japanese yam, radish, and radish, create a groove in advance at the bottom, and turn the root vegetables into the groove along with the soil from the root vegetable planting row. Harvesting devices are known. In addition, it is equipped with a trench bottom and a digging bottom that is located at the rear in the direction of work progress and on the opposite side of the trench bottom and digs a deeper trench than the trench bottom, so that root vegetables can be planted without overturning. There are also known harvesting machines that soften the soil in the rows to make it easier to extract the soil, and a typical example of this type of harvesting machine is JP-A-59-175812. .

[Problem that the idea aims to solve]

With the above-mentioned harvesting machine, the root vegetables may be exposed to the soil, and in severe cases, they may become buried in the soil and become lost when the worker harvests them, resulting in unharvested crops. However, there were problems such as a decrease in commercial value due to soil covering the stems and leaves.

[Means to solve the problem]

Therefore, this invention is equipped with an elevating mechanism that moves the excavation bottom up and down, and a lodging prevention blade attached to the back of the excavation bottom and extending from the opposite side of the excavation bottom, and the mechanism is equipped with a lifting mechanism that moves the excavation bottom up and down. The soil in the deep groove formed by the digging bottom is moved into the shallow groove, and the lodging prevention blade is used to prevent the lodging of long radish vegetables into the deep groove.

[Effect]

With the above configuration, the root vegetables to be dug and harvested are not buried in the soil or covered with inverted soil, and the harvest can be easily collected. Moreover, the commercial value of the harvested product will not be lowered.

【Example】

Embodiments of this invention will be described below with reference to the attached drawings. In the figure, reference numeral 1 indicates a work machine frame commonly called a bottom frame, and an offset guide rail 1 is installed parallel to the front frame 1A.
B is provided, and this offset guide rail 1B
A moving frame 2 is attached along. This moving frame 2 includes an offset cylinder 2.
One end of A is attached to the offset guide frame 1, and by expanding and contracting this offset cylinder 2A, the movable frame 2 moves by the required stroke.
It is now possible to move along line B. The movable frame 2 has a rearwardly protruding portion at its rear end, and a slide case 2B with open upper and lower ends is attached to this portion. A beam 3A constituting the digging bottom unit 3 is inserted into the slide case 2B.
A digging bottom unit 3 is formed by attaching a digging bottom 3B, a side pressure plate 3C, and a sear 3D to the lower end of the bottom. In addition, an elevating cylinder 4 is provided at the upper end of the beam 3A.
A cylinder 4A is attached thereto, and the end of this piston rod 4B is attached to a bracket 2C provided on the slide case 2B. The front end of the lodging prevention blade 5 is pivotally attached to a mounting member 4C extending downward from the slide case 2B, and is constructed between the mounting member 4C and the lodging prevention blade 5 by pivots 5B and 5C. The attitude of the lodging prevention blade 5 in the horizontal plane is determined by the turnbuckle 5A, and the lodging prevention blade 5 extends toward the rear of the digging bottom unit 3 in a direction diagonal to the work progress direction. . Furthermore, in front of the digging bottom unit 3 and on the soil inversion side by this digging bottom 3B,
The groove bottom 6 is located with the upper end of the beam 6A attached to the movable frame 2. Next, a description will be given of a harvesting operation using the device for digging up long radish vegetables according to this invention. First, the depth of the digging bottom 3B is determined to be approximately equal to the root tip of the long radish vegetables K by expanding and contracting the lifting cylinder 4, and towing work is performed using a tractor. A shallow groove _G1 is formed on the side of the root vegetables K by the groove bottom 6 (FIG. 4A). Shallow groove centered around root vegetables K
On the opposite side to G ₁ , in other words, diagonally below the position where the shallow groove G ₁ was formed in the previous work process, a deep groove G ₂ dug by the digging bottom 3B of the digging bottom unit 3 is formed. At the same time, the soil is moved to the adjacent shallow groove _G1 (Fig. 4B), and the lodging prevention blade 5 pushes down the root crops K slightly toward the shallow groove _G1 , and the root crops K are moved to the deep groove _G2. This prevents them from falling inside (Figure 4C). Dig the soil in deep places for root vegetables K to the bottom 3B.
Since the vegetables have been expanded and softened, workers can simply collect them as they would pick up long radish vegetables. In the above description, a type in which only the digging bottom is moved up and down has been shown, but the lodging prevention blade may also be made to be able to move up and down together.

[Effect of the idea]

As is clear from the above explanation, the long radish vegetables digging device of this invention has a groove bottom that forms a shallow groove around the long radish vegetables to be harvested, and a vertically movable groove that forms a deep groove on the opposite side. The structure is constructed by providing a lodging prevention blade that extends toward the shallow trench behind the digging bottom and obliquely to the direction of work progress, so that long root crops can be easily grown at that depth. The excavation bottom can be used to properly dig to the appropriate depth. In addition, the lodging prevention blade prevents the long radish vegetables from being buried or covered by the inverted soil, making it possible to easily harvest the vegetables without leaving unharvested crops.
