Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a direct seeding machine equipped with a hopper incorporating a feed roll for feeding out seeds, a chute connected to the hopper, a float for planting furrows, and the like.

``Prior Art'' Conventionally, as shown in Japanese Utility Model Application Publication No. 54-78617, there has been a technique in which a hopper, a flow, etc. are provided in a walking-type traveling body equipped with running wheels.

"Problems to be Solved by the Invention" The above-mentioned prior art had an engine in front and a float in the rear of the running wheels, which are the center of forward and backward tilting of the aircraft. Since the sowing mechanism with the engine was placed at almost the same position as the running wheels, the front part of the aircraft where the engine was installed was heavier than the rear part, making it difficult to maintain the longitudinal balance of the aircraft, and the position of the running wheels. The sowing mechanism and the sowing position of the float are far apart, and it is not possible to easily shorten the time difference between the seed dispensing by the sowing mechanism and the seed embedding in the float, and it is necessary to provide a forced-feeding mechanism for dispensing the seeds. There were problems such as the difficulty in simplifying the seed dispensing structure and improving the sowing function.

Also, JP-A No. 50-121011 and Utility Model Application No. 51-
As shown in the publications of No. 30719, there was a technique in which a seeding mechanism was provided above the seeding notch of the float to bring them closer together, but since the float was simply placed between the left and right running wheels, There was a problem in that it was not easy to increase the size of the floats by providing floats on the outside of the running wheels.

``Means for Solving the Problems'' However, the present invention provides a direct seeding machine in which an engine is disposed at the front of the machine body and a steering handle is extended at the rear of the machine body, and a float is disposed at the rear side of the running wheels. In addition, a seeding mechanism having a hopper, a feed roll, etc. is provided above the float, a seeding notch of the float is provided below the seeding mechanism, and a float placed outside the running wheel is provided with independent upper and lower parts. It is characterized by being attached so that it can move freely.

"Function" Therefore, the rolling reaction force of the running wheels can be well received by the float on the rear side of the running wheels, and by providing a seeding mechanism such as a feed roll above the float, the sowing mechanism and the engine can be easily received. In addition, since the float's sowing embedding position is provided below the sowing mechanism such as the dispensing roll, the seed dispensing position and the seed embedding position can be connected with the shortest distance, and the seed Even if the seed is dropped under its own weight, the time lag between feeding and burying it in the ground can be reduced, and compared to conventional seed feeding structures, the structure of seed feeding can be simplified and the sowing function can be improved. Since the floats are moved up and down independently, even if the field surface is undulating after puddling, the floats can be moved to follow the field surface, maintaining uniform sowing depth on the left and right sides, and improving workability such as handling operations. This is something that can be easily improved.
