Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a bamboo shoot digger.

(b) Conventional technology Conventionally, only the tips of bamboo shoots that reproduce in the forest are
The bamboo shoots protrude above the ground, and the bamboo shoots themselves are hidden underground.
The digging process involves digging the soil around the tip of the bamboo shoots to the roots located about 40cm to 50cm above the ground (using agricultural implements such as straws), cutting the bamboo shoots with the exposed roots, and removing the bamboo shoots. was being collected.

(c) Problems that the invention seeks to solveHowever,
Collecting bamboo shoots using agricultural tools such as hoes requires digging around the edges to a depth of about 40 to 50 cm, making the work complicated and taking about 20 to 30 minutes per bamboo shoot.
This required a great deal of effort and was very inefficient. Moreover, during excavation work, the blades of agricultural implements damage the surface of the bamboo shoots, reducing the commercial value of the bamboo shoots.

(d) Means for Solving the Problems In the present invention, a longitudinal power transmission shaft is connected to the output shaft of the prime mover, and a driving sub-ocket is connected to the tip of the transmission shaft, and at right angles to the transmission shaft. A floating sprocket is arranged at a certain distance away from the drive sprocket in the direction, and the chainsaw is rotatably suspended on the same sprocket to form the excavation part, and the power transmission shaft can be bent from the middle part. year,
It is an object of the present invention to provide a bamboo shoot digging machine in which the excavating section is configured to be tiltable with respect to a power transmission shaft (4).

(e) Operation In this invention, the excavating part of the bamboo shoot digging machine is located on the ground surface on the side of the tip of the bamboo spear, and the chainsaw of the excavating part is rotated by the power of the prime mover, thereby removing bamboo shoots. This is to form a hole in the ground of the side force.

At that time, the excavation part is placed on the ground in an inclined state, and the ground is excavated by the driving sprocket located at the base end of the excavation part, and the chain saw is rotated in an inclined state. The soil is released outward by movement.

Next, the bamboo shoot digging machine bends the middle part of the power transmission shaft so that the excavation part is in a substantially horizontal state within the hole in the ground, and the rotating chainsaw of the excavation part is brought into contact with the base of the bamboo shoots to extract the bamboo shoots. The root portion of the cutter is cut approximately horizontally.

Furthermore, by bending the midway portion of the power transmission shaft in the vertical direction, the excavating section can perform cutting work while excavating the soil around the bamboo shoots.

(f) Effects Therefore, according to the present invention, the bamboo shoot excavation work and its cutting work can be performed easily and quickly through a series of operations of the same bamboo shoot digging machine, reducing the bamboo shoot collection time and improving work efficiency. This has the effect that bamboo shoots can be collected by a simple operation without requiring much effort.
