Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrinkle forming apparatus and a wrinkle forming pretreatment plate that are attached to a traveling device such as a passenger tractor and move soil while moving to create a ridge.

  In a conventional hull forming device, a tilling rotary that is rotated by a rotation drive system of the traveling device is attached to a traveling device such as a riding tractor, and a soil pusher is provided behind the tilling rotary. Such a dredge forming device forms a ditch by driving the soil to the side with a rotary rotary while driving and forming a groove to raise the soil to the side, pressing down the slope of the raised soil with the earth presser .

  Various devices have been devised in the cocoon forming apparatus to form the cocoon in a uniform manner. In the scissors and brazing machine disclosed in Patent Document 1, the earth presser presses down the slope of the soil that has been raised and swung by the rotational drive system of the traveling device to suppress the slope of the trough and tack. Can be crushed.

FIG. 4 shows an example of making a plurality of ridges on a wide cultivated land using such a ridge forming apparatus. First, the saddle forming apparatus 1 is caused to travel in one direction by a riding tractor or the like. Here, the dredge forming apparatus 1 is provided with three earth pressers 2, and when run once, three valleys 3 are formed on the cultivated land, and two peaks are between the three valleys 3. Part 4 is formed. A slope 5 that is an inclined surface is provided between the peak 4 and the valley 3, and the first peak A is provided by the peak 4 and the pair of slopes 5. On both sides in the running direction of the ridge forming apparatus 1, slopes 5 are provided on one side so as to be inclined toward the summit 4. And when the dredging device 1 comes near the peripheral edge of the cultivated land, the dredging device 1 is turned over repeatedly, adjacent to the first reed A and forming a first reed A parallel to the next while returning parallel. . The slope 5 of only one side formed on both sides in the running direction of the heel molding apparatus 1 becomes the first heel A by the slope 5 formed next. By repeating this, a plurality of first ridges A parallel to each other are formed on almost the entire surface of the cultivated land. However, a space where the ridge forming apparatus 1 is folded back remains in the peripheral portion of the cultivated land. Therefore, in order to effectively use the cultivated land area, the ridge forming apparatus 1 is moved substantially at right angles to the first ridge A, and the second is substantially orthogonal to the first ridge A near the end of the first ridge A.畝 B may be formed.

  Next, an example when making a plurality of cocoons on a wide cultivated land with the cocoon forming apparatus 10 will be described with reference to FIG. First, the wrinkle forming apparatus 10 is caused to travel in one direction. Since the dredging device 10 is provided with three earth pressers 30, three troughs 3 are formed on the cultivated land when it is run once, and two peaks are formed between the three troughs 3. Part 4 is formed. A slope 5, which is an inclined surface, is provided between the peak 4 and the valley 3, and the first ridge A is provided by the peak 4 and the pair of slopes 5. On both sides in the traveling direction of the ridge forming apparatus 1, only one of the slopes 5 is provided with an inclination toward the peak 4. And when the cocoon forming device 10 comes near the periphery of the cultivated land, the cocoon forming device 10 is repeatedly turned over, adjacent to the first heel A, and forming a first heel A parallel to the next while returning parallel. . The slope 5 of only one side formed on both sides in the running direction of the heel molding apparatus 1 becomes the first heel A by the slope 5 formed next. By repeating this, a plurality of first reeds A parallel to each other are formed on almost the entire surface of the cultivated land. At this time, a space where the ridge forming apparatus 10 is folded back remains in the peripheral portion of the cultivated land. In view of this, the hook forming apparatus 10 is caused to run at a substantially right angle with respect to the first hook A in this portion to form a second hook B that is substantially orthogonal to the vicinity of the end of the first hook A.

  When forming the second kite B, the kite-forming pretreatment plate 46 is attached to the side facing the first kite A in the traveling direction. At this time, the cultivated soil at the end of the first reed A moves to the inner side in the traveling direction in contact with the pretreatment plate 46 for reed forming, and near the valley bottom 30d of the earth press 30 closest to the first reed A Therefore, the cultivated soil is not pushed out to the first side A when the earth presser 30 passes. As a result, the slope 5 is not formed at the end of the first rod A, and the conventional raised portion 6 as shown in FIG. 4 is not generated. For this reason, the trough 3 of the first reed A is not filled, the reed 3 is opened to the side, and the drainage of the 1st reed A is secured.

  According to the wrinkle forming apparatus 10 and the wrinkle forming pretreatment plate 46 of this embodiment, the second reed B that intersects the first reed A can be easily formed at the end of the first reed A. The first pretreatment plate 48 of the pretreatment plate 46 for dredging is a freely rotating disc, and can move the cultivated soil with less resistance. The cultivated soil moved by the first pretreatment plate 48 of the first pretreatment plate 48 is surely moved by the second pretreatment plate 50 to the vicinity of the valley bottom 30d of the earth presser 30 and reliably cultivated to the first ridge A. This prevents the raised portion 6 from being formed. Since the valley portion 3 of the first base A is not filled, drainage of the first base A can be secured. The work of removing the raised portion 6 manually is unnecessary, there is no burden on the operator, and the work efficiency is good.

  The position of the cocoon forming pretreatment plate 46 can be adjusted by the adjusting member 36 in the vertical direction and in the horizontal direction substantially perpendicular to the traveling direction, such as the size of the tillage rotary 26 and the distance from the first heel A. It is possible to change freely according to. The cocoon-forming pretreatment plate 46 can be attached to either side of the traveling direction, and can be changed according to the shape of the cultivated land. When not needed, it can be easily removed. The cocoon forming pretreatment plate 46 has a simple structure in which the first pretreatment plate 48 and the second pretreatment plate 50 are attached to the support member 44, and can be attached to and used on various types of traveling devices 12. .

  Note that the cocoon forming device and the cocoon forming pretreatment plate of the present invention are not limited to the above-described embodiments, and can be attached to various types of traveling devices such as a walking type. The number, shape, etc. can be changed. The shape of the pre-processing plate for molding can also be changed, and either the first pre-processing plate or the second pre-processing plate may be used. The pre-processing plate holding member and the adjustment member for attaching the pre-processing plate for forming the cocoon to the traveling device can also be changed as appropriate. The cocoon forming apparatus is not limited to the case where the second cocoon orthogonal to the first cocoon is formed, and can be used even when there is a section where irrigation canals and other crops are planted beside the cultivated land.
