Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a field leveling machine for leveling a field.

[0002]

[Prior art]

 Conventionally, as this kind of machine, the field arranging machine of Japanese Utility Model Publication No. 57-26936 is known. This field tractor is fixed to the bucket support attached to the link mechanism of the tractor by the locking device at all times and supports the bucket so that it rotates backward when unlocked, and is formed at the center of the front part of the bucket. A plow is installed diagonally through the shaft in front of the soil receiving port.By driving the tractor, the soil of the convex part of the rice field is stored in the bucket by the plow, and the lock is released to insert the bucket into the concave part of the rice field. It is the one to put the soil.

[0003]

[Problems to be solved by the device]

 In the conventional soil leveling machine, the soil receiving opening is formed at one central part in the front part of the bucket, and the plow is obliquely provided in front of the soil receiving opening. There was a problem that the traveling distance of the tractor had to be increased in order to store a predetermined amount of soil in the bucket.

An object of the present invention is to solve the above problems and to provide a rice field arranging machine capable of shaving a large amount of soil in a short time.

[0005]

[Means for Solving the Problems]

 The present invention supports a bucket so that it is always fixed in a normal position by a locking device to a bucket support attached to a link mechanism of a tractor, and rotates backward when unlocking, and a soil receiving opening formed in the front part of the bucket. In the rice field leveling machine with a diagonally installed plow, the soil leveling machines with the obliquely installed plow are arranged on both sides of the bucket, respectively.

[0006]

[Action]

 With the above configuration, it is possible to scrape off the soil of the paddy field with a pair of left and right plows, and it is possible to scrape off a large amount of soil in a short time.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a three-point link mechanism of a tractor 2. A front end of the three-point link mechanism 1 is connected to a bucket support 3 having an L-shaped front surface and a L-shaped side surface. Reference numeral 4 denotes a bucket. The bucket 4 comprises a box-shaped bucket body 5, an L-shaped frame body 6 which integrally supports the front and bottom surfaces of the bucket body 5 and the lower portion of the frame body 6. The front side of 6A is rotatably connected to the front side of the lower portion 3A of the bucket support body 3 via a shaft 7. Further, a lock device 8 is rotatably provided on the upper portion 3A of the bucket support body 3, and a lock receiving portion 9 provided on the upper portion 6B of the L-shaped frame body 6 is engaged with the lock lever 8A. The possible lock portion 10 is fixed, and the lock lever 8A is always urged by a spring 11 so that the lock portion 10 is locked to the lock receiving portion 9.

Further, the bottom surface 15 of the bucket main body 5 including the front surface 11, the left and right side surfaces 12 and 13 in the shape of a slant plate, the rear surface 14 provided with the lower opening 14A, and the bottom surface 15 has earth receiving openings 16 and 16A and the earth receiving openings. There are plows 17, 17A attached to 16, 16A. The soil receiving port 16 is arranged along the right side surface 13 and is open to the front surface 11 side. The plow 17 attached to the soil receiving port 16 is obliquely installed so that the lower end 18 is obliquely forward. Further, this plow 17 is mounted so that the lower end 18 of its axis 19 faces outward. A mounting shaft 22 is rotatably connected to the rear surface of the plow 17 via a pair of left and right mounting arms 20 and 21, and the right mounting arm 21 is formed longer than the left mounting arm 20. A winding spring 23 is attached to the mounting shaft 22, and the winding spring 23 is provided so as to constantly urge the plow 17 downward at its lower end 18. Reference numeral 24 is a stopper that regulates the angle of the plow 17, and the tip of a stopper rod 25 that is rotatably connected to the rear surface of the plow 17 slidably penetrates the rear portion of the soil receiving opening 16 and does not fall off at that end. A member 25 is provided. Similarly, the soil receiving port 16A is arranged along the left side surface 12 and is open to the front surface 11 side. The plow 17A attached to the soil receiving port 16A is obliquely installed so that the lower end (not shown) is diagonally forward. Further, this plow 17A is mounted so that its lower end faces the outside. This attachment is rotatably connected to the rear surface of the plow 17A via a pair of left and right attachment arms 20A and 21A. Reference numeral 27 is a lever standing on the upper part of the front surface 11 of the bucket body 5.

Next, the operation of the above configuration will be described. When shaving off the soil of field A, first plow 17, 17A drives tractor 2 so that it touches field A, and when tractor 2 is advanced, field soil B is scraped off by plows 17, 17A, It is accommodated in the bucket body 5 through the soil receiving openings 16 and 16A along the plows 17 and 17A, respectively. At this time, the soil is accommodated toward the center side of the bucket body 5 as shown by the arrow B, due to the slanting of the axis 19 of the plows 17 and 17A. After the predetermined soil is stored, the bucket 4 is lifted together with the bucket support 3 by the three-point link mechanism 1 as shown in FIG. 2 and is transported to the recess of the field A. Then, when the lock lever 8 is operated to release the lock portion 10 from the lock receiving portion 9, the rear surface 14 is rotated about the shaft 7 so as to descend, and the soil B stored in the bucket body 5 is opened downward. Emitted from part 14A. After that, to lock the bucket 4 again, the bucket 4 is rotated by operating the lever 27 so that the lock portion 10 is locked to the lock receiving portion 9.

As described above, in the above-described embodiment, since the plows 17 and 17A are arranged on both sides of the bucket 4, the soil of the field A can be scraped off by the pair of left and right plows 17 and 17A. As a result, a large amount of soil can be stored in a short time and the efficiency of agricultural work can be improved.

Further, by disposing the axis 19 so that the lower ends 18 of the plows 17 and 17A face outward, the soil B scraped by the plows 17 and 17A can be collected in the center of the bucket body 5. . For this reason, the center of gravity of the soil leveling machine is prevented from being biased, and the tractor 2 can be operated with peace of mind.

The present invention is not limited to the above-described embodiment. For example, in the embodiment, the pouch is provided on the bottom surface of the bucket body, but the soil receiving opening is provided on the front surface of the bucket. Various modifications are possible, such as a plow may be provided in the soil receiving port.

[Effect of device]

 The present invention supports a bucket so that it is always fixed in a normal position by a locking device to a bucket support attached to a link mechanism of a tractor, and rotates backward when unlocking, and a soil receiving opening formed in the front part of the bucket. By disposing the soil receiving openings on both sides of the bucket in the rice field leveling machine in which the plow is installed obliquely, a large amount of soil can be shaved off in a short time.
