Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hand-operated power mud scooping machine that scoops and transports mud from rice fields, etc., and levels the ground.

(Prior art) A power tiller that has two wheels that rotate by power and is equipped with a hand-push part is well known in the past, and various tools for agricultural work are attached to the rear of the main unit, and a rake for leveling the soil is used. Although there is a tool called ``mud'', it was not possible to level the ground because it merely leveled the soil and could not transport the mud.

During the rice planting season, because the seedlings are small, it is necessary to keep the ground level in the rice field in order to fill the rice field with water to a certain depth, but in the past, mud from high places had to be transported by hand to low places, which required a lot of effort. The problem was that it required time.

(Purpose) The present invention involves manually pushing a vehicle body with wheels that rotate by power, while the mud scooping plate enters a predetermined amount of mud in the rice field, scoops and transports the mud, leveling the ground of the rice field, and then moving the mud scooping board into the mud. The aim is to solve the problems of the conventional method by making it possible to freely adjust the angle and depth of penetration.

(Structure) In order to achieve the above object, the present invention is equipped with ground pressing plates at both ends of the horizontal shaft so that their positions can be adjusted up and down toward the rear of the vehicle body, and mud scooping plates whose lower part is curved toward the front are attached to the horizontal axis. Pivotably attached to a shaft so as to be able to swing,
It is equipped with a locking means for holding the mud scooping plate at a predetermined angle, and the tip of a connecting bar protruding in front of the horizontal axis is detachably attached to the rear connecting part of the vehicle body having wheels that rotate by power and a hand push part. This is a characteristic feature. The following will be specifically explained based on examples.

First, mud scooping device A will be explained. 1 has a horizontal shaft with supporting rods 1a protruding rearward from both ends thereof,
Tightening tube 2 with a vertical groove 2a formed at its tip
is fixed. 3 is a spoon-shaped ground pressing plate whose shaft 3a is rotatably inserted into the branch pipe 4, and retaining rings 5 and 6 are fixed to the part protruding from the branch pipe 4, so that the position can be adjusted up and down within that range. It's becoming like that. This branch pipe 4 is inserted into the tightening tube 2, the ground pressing plate 3 is directed toward the rear of the vehicle body, and is fixed to the tightening tube 2 with bolts and nuts at a predetermined height. 7 is a mud scooping plate rotatably attached to the horizontal shaft 1 with a ring 7a,
The lower part is a mud scooping part 7b that curves forward. A connecting bar 8 is located in front of the middle part of the horizontal axis 1.
A connecting tool 9 is fixed thereto, having an opposing vertical wall 9a at its tip and a pin insertion portion 9b formed at the outer end of the vertical wall 9a. An engagement plate 10 having a plurality of engagement recesses 10a formed in a comb-teeth shape is integrally fixed to one intermediate side of the connection bar 8 so as to face rearward. 11
is a locking rod that is pivotally attached to the rear surface of the mud scooping plate 7 with a pin 12 so as to be able to swing only in the lateral direction, and is constantly pulled by a spring 13 and press-fitted into one of the engaging recesses 10a. There is. 14 is a connecting rod between the connecting tool 9 and the mud scooping plate 7.

Reference numeral B designates a vehicle body having two wheels 21 rotated by a motor 20 and a hand push portion 22, and the rear portion of the vehicle body has a lower wall 23a facing upward, and a connector 23 having a pin insertion hole 23b is fixed to each body.

When in use, as shown in Fig. 6, insert the connector 9 of the mud scooping device A into the connector 23 of the vehicle body B, align the pin insertion hole 23b with the pin insertion part 9b, and insert the pin 24 from above to connect. .

Next, the effect will be explained. Resisting the elasticity of the spring 13, pull the locking rod 11 laterally around the pin 12 to remove it from the engagement recess 10a, and then rotate it back and forth to tilt the mud scooping plate 7 at a predetermined angle. , at that position, release the hand and lock the locking rod 11 in the engagement recess 10a at that position. Next, loosen the bolts and nuts on the tightening pipe 2, and adjust the height of the ground pressing plate 3 by moving the branch pipe 4 up and down depending on the condition of the rice field, so that the mud scooping plate 7 is placed in the mud of the rice field to a predetermined depth. Try to get into it. When the motor 20 is activated to rotate the wheels 21 and the hand push part 22 is pushed to move the vehicle body B in a predetermined direction, the mud scoop part 7a moves a predetermined amount depending on the depth and angle at which the mud scoop plate 7 enters the mud. Move forward while scooping up mud and transport it to a designated location. Since this ground pressing plate 3 can freely rotate around the branch pipe 4, when the direction of the vehicle body A is changed, the ground pressing plate 3 also changes its direction in the same way, so that the direction of the vehicle body can be smoothly changed.

(Effects) According to the present invention, ground pressure plates are installed at both ends of the horizontal axis so that their positions can be adjusted up and down toward the rear of the vehicle body.
A mud scooping plate whose lower part is curved toward the front is pivotally attached to the horizontal axis so as to be able to swing, and the coupling is provided with a locking means for holding the mud scooping plate at a predetermined angle and protrudes in front of the horizontal axis. The tip of the bar is removably attached to the rear connection part of the car body, which has a wheel that rotates with power and a hand push part, so you can scoop mud from the rice field and transport it from a high place to a low place while pushing the hand part of the car body. can efficiently level the ground with little effort.
