Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables the harvesting of root vegetables grown in multiple cultivation rows in a field by digging a trench at the root edge of the root vegetable planting row using a trench excavator. The present invention relates to an improvement in a method for harvesting root vegetables, which is carried out by digging up root vegetables into the grooves while breaking the grooves.

To harvest root vegetables cultivated in fields with multiple planting rows, a trench excavator is used to dig deep trenches around the roots of the root vegetable planting rows. Means for digging root vegetables into trenches are known in the art. In addition, when a groove for digging root vegetables is excavated by a groove excavator near the roots of the planting row of root vegetables, the soil excavated to excavate the groove is placed in the groove excavator. The conveyor keeps the
Means for simultaneously excavating a trench for digging root vegetables and backfilling the trench from which root vegetables have been dug, by feeding the root vegetables into the trench that has been excavated first and from which root vegetables have been taken out. This method has also been known for a long time as described in Japanese Utility Model Publication No. 15699/1983.

However, in all of these conventional methods, a groove for digging root vegetables is excavated one by one for each planting row, and the root vegetables are dug out by this. , trenches for digging root vegetables must be dug for the number of root vegetable planting rows;
There is a problem that work efficiency does not improve.

In addition, in order to counter this problem, for example,
As stated in Publication No. 50-75929 or Japanese Utility Model Publication No. 144741/1989, the soil within two desired row spacings of the planting rows for root vegetables is excavated or tilled. If the root vegetables in two planting rows are dug up together, the dug soil and the traces of the root vegetables will interfere with the stable running of the trench excavator's wheels. As a result, it becomes impossible to perform the work of harvesting root vegetables two rows at a time, which leads to the problem of lowering work efficiency.

The present invention is intended to solve the above-mentioned problems occurring in a means for harvesting root vegetables, in which a trench is dug near the roots of root vegetables using a trench excavator, and the roots are dug into the trench. The harvesting process involves digging a trench for root vegetables with a trench excavator and digging the root vegetables into the trench. The purpose is to provide a new means of harvesting.

Therefore, the present invention has been completed based on the knowledge obtained through various studies for the above-mentioned purpose. That is, a wide excavation body is installed on a trench excavator that is run so as to straddle two planting rows selected from among the planting rows for root vegetables.
Within the row spacing of those two planting rows, one wide trench spanning between each root edge of those two planting rows is excavated, and within that trench, positions are placed on the left and right of the trench. When digging out root vegetables that are planted in a row, the soil excavated for trench excavation is transferred to one side in the left and right direction perpendicular to the row direction of the planting row by a conveyor installed in the trench excavator. If it is carried out within the row spacing between the adjacent next planting row and the next planting row, which is one row spacing from the row spacing of the planting row, After harvesting root vegetables in two planting rows, when digging trenches between the rows to harvest root vegetables in the next planting row and the next planting row. , an unexcavated row gap remains on both the left and right sides of the row spacing, and by passing the left and right wheels of the trench excavator through this space, the trench excavator can run stably, making continuous work possible. I thought it was possible. When root vegetables were harvested in this manner, it was possible to harvest two rows at a time without any problems.

From this, in the present invention, as a means to achieve the above-mentioned object,
Root vegetables such as burdock are cultivated in multiple planting rows with the width of the row spacing as narrow as possible, and are grown over two adjacent planting rows on the left and right selected as desired among the multiple planting rows. Let's run the trench excavator, part 2
One trench with a width extending between each root edge of the left and right planting rows is excavated within the row spacing of the planting row using a wide excavating body installed on the trench excavator, and The excavated soil dug up from the trench is conveyed by a conveyor installed in the trench excavator, on one side in the left and right direction perpendicular to the aforementioned planting rows, with a row spacing of one row from the row spacing of the two planting rows. Soil is removed within the row spacing of the above mentioned two planting rows, and then the root crops of the two planting rows adjacent to the left and right are dug into the aforementioned trench, and then the row spacing of the two planting rows is The trencher excavates one wide trench with the excavating body of the trencher within the row spacing of adjacent next and successive planting rows with a row spacing of one row. By repeating the process of backfilling the excavated soil by the conveyor into the trench excavated in the step, and digging out the root vegetables of the next and next planting rows into the newly excavated trench,
This invention proposes a method for harvesting root vegetables, which is characterized by continuously harvesting root vegetables planted in multiple rows, two rows at a time.

Next, embodiments will be described in detail with reference to the drawings.

First, root vegetables a are as shown in Figure 1.
Cultivation is carried out in a field using a large number of aligned planting rows A, with row spacing set as narrow as possible.

Next, two adjacent planting rows A, A (for example,
Insert trench digging machine B into the field so as to straddle the two planting rows located at one end of the field.
An excavating body 2 equipped on the machine body 1 is positioned so as to act within the row spacing between the left and right planting rows A, A, and the trench W is excavated by the excavating body 2.

The trench excavator B used here has a machine body 1 that is driven and travels and has a pair of running wheels 10, 10 on the left and right and a pair of drive wheels 11, 11 on the left and right, and a chain 20 that rotates endlessly. An endless belt-type excavation body 2 is equipped with an excavation blade 21 and a soil transport plate 22,
It goes without saying that a conventionally known type that is mounted so as to be rotatable up and down may be used, but the excavation body 2 mounted on the machine body 1 has an excavation action width d equal to ... is formed into a wide excavation body 2 close to the row spacing D, so that the left and right planting rows A, from the root edge of one planting row A to the root edge of the other, are formed within the row spacing D. A wide trench W spanning the area is excavated.

By the way, the groove W excavated between the rows in this way is used to break down the wall surface on the side adjacent to the planting row A and take out the root vegetables a into the groove W. Therefore, widening the width of the groove W only increases the middle part of the groove W that is not actually used.
When excavating a trench, the excavating body 2 mounted on the machine body 1 of the trench excavator B is replaced with the excavating bodies 2', 2' having a narrower working width, as shown in FIGS. 5 and 6. The excavated bodies 2', 2' are arranged in parallel in rows, and the respective excavated bodies 2', 2' are arranged side by side in the space between the planting rows A and 2, which are arranged adjacently on the left and right. As shown in FIG. 7, narrow grooves W', W' may be excavated at the roots of the left and right planting rows A, A, respectively.

Therefore, when a wide groove W is excavated by the wide excavation body 2 described above, and when two narrow width grooves W', W' are excavated by two narrow width excavation bodies 2', 2' arranged in parallel. Even when excavating in parallel with the planting rows A, the soil excavated by the excavator is carried out by the conveyor 3 in one direction in the left and right direction orthogonal to the planting rows A. The conveyor 3 may be an appropriate one such as a screw auger or a belt conveyor that is normally equipped on the trench excavator B, but as shown in FIGS. 4 and 7, It is arranged so that it is carried out from the row spacing D of the attached rows A and A to the next row spacing that is an integral row spacing.

In this way, two adjacent planting rows A,
When trenches W (or trenches W', W') are excavated within the row spacing D of A by trench excavator B, the field will be in a state as shown in Figure 3 (or Figure 7) in the first step. Therefore, when this work process is completed (while this work process is in progress if there are other workers in addition to the driver operating trench excavator B), the excavated trench W can be used. Then, dig out the root vegetables a and a in the left and right planting rows A and A.

Next, as shown in FIG. 4 (or FIG. 8), the groove excavator B is moved to the side opposite to the soil discharge direction of the conveyor 3, and removes one row from the row interval D where the trench W was excavated. The excavated body 2 is placed in the field so as to straddle the row interval D with an interval D, and the excavation body 2 is placed within the row interval D.
is applied to excavate the groove W in the same manner as in the first step described above.

At this time, the groove excavator B, which starts traveling across the row spacing D for digging the trench W, has its wheels located on the side of the trench W excavated in the previous step traveling across the row spacing D. Since the machine travels through the unexcavated row spacing left between the row spacing set to dig a new groove W, the excavation process runs stably in the same way as the excavation stroke of the first row spacing.

In this work process, the excavated soil is carried out by the above-mentioned conveyor 3 into the trench W in which root vegetables have been dug in the first work process. The trenches that have been dug up for root vegetables will now be backfilled.

Then, after or during this work process, the root vegetables a, .

Next, on the opposite side of the conveyor 3 from the soil removal direction, the trench excavator B is run so as to straddle the row intervals that are one row apart, and the same work process is performed, and this is repeated. , each of the arranged planting rows A... root vegetables a... are dug up one by one, two rows at a time, by continuous work.

As explained above, the method for harvesting root vegetables according to the present invention involves cultivating root vegetables such as long potatoes and burdock in a large number of planting rows with the width of the row spacing as narrow as possible. Run the trench excavator so as to straddle two adjacent planting rows on the left and right selected as desired, and within the row spacing of those two planting rows,
A wide trench extending between each root edge of the left and right planting rows is excavated using a wide excavating body installed on the trench excavator, and the excavated soil dug up from the trench is poured into the trench. Using a conveyor installed in the machine, soil is discharged on one side in the left and right direction perpendicular to the planting rows, within a row spacing that is one row spacing from the row spacing of the two planting rows, and then , dig out the root vegetables in the two adjacent planting rows on the left and right into the trench, and then,
The excavation body of the trench excavator excavates one wide strip within the row spacing of the adjacent next and next planting rows, which is one row spacing from the row spacing of the two planting rows. While excavating a trench, the excavated soil is backfilled into the trench excavated in the step by the conveyor included in the trench excavating machine, and the next and subsequent planting rows are placed in the newly excavated trench. By repeating the process of digging up root vegetables, root vegetables planted in multiple rows can be harvested in succession, two rows at a time. The trench excavator B, which enters the cultivated field in parallel planting rows, runs stably using the row spacing that is left unexcavated every other row, and digs when excavating the trench. Since the soil will backfill the grooves excavated in the previous process within the row spacing, the work of harvesting root vegetables two rows at a time can be done continuously without any hindrance.

Therefore, according to the method of the present invention, root vegetables cultivated in a large number of aligned planting rows are dug by using a trench excavator to create trenches around the roots of the planting rows of the root vegetables. Harvesting work in which root vegetables are excavated in a trench can be dug out in two planting rows at a time and can be carried out continuously.
