Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a leaf tobacco cutting machine that cuts and harvests the stem base of leaf tobacco grown in a ridge.

[What conventional techniques and inventions try to solve Problems to be solved〕

Conventional leaf tobacco cutters are wheel-wheel-style, run in a soft manner, and cut at the base of the leaf tobacco stalk, making running extremely unstable, making it difficult for the operator to maintain correct running and cutting conditions. required a lot of effort.

[Means for solving problems]

The present invention solves this problem, and its structure will be described in detail as follows with reference to the accompanying drawings showing embodiments.

A height and a gap through which the cut remaining stems can pass are provided in the left and right middle part of the traveling body 4, which has left and right running wheels 2.2 degrees located between the ridges 1 and left and right tail wheels 3.3 degrees located behind them. A tower-shaped machine frame 5 having a shape seen from the front is erected, and this tower-shaped machine frame 5
An upper transmission shaft 6 is horizontally mounted on the upper part of the tower-shaped machine frame 5, and a lower transmission shaft 8 is horizontally mounted on lower horizontal arms 7 protruding from the left and right sides of the lower part of the tower-shaped machine frame 5. and the inner end of chain 9
・The left and right running wheels 2.2° are linked by 1° and a belt, and the power from the engine 11 is distributed to one of the lower transmission shafts 8 to freely drive the left and right running wheels 2.2°. death,
Left and right guide rods 12, 12 are installed on the lower front side of this tower-shaped machine frame 5.
A straight guide mechanism a is provided for clamping the stem base of leaf tobacco with two side-by-side tobacco leaves, and a stem cutting device 13 is provided at a predetermined height in front of the tower-shaped machine frame 5. A stem cutting guide mechanism in which a guide rod 14 is provided protrudingly, a left guide rod 15 is provided protrudingly from a tower-shaped machine frame 5 to face the right guide rod 14, and to correctly position a leaf tobacco stem 17 in a stem cutting section 16. It is characterized by having the following.

Further, the cutting device 13 is provided with a cutting board 18 for cutting the stem 17 and two-piece groove cutting boards 19 and 19' for cutting out grooves for hooking the rope.

25 is a transmission shaft, 26 is a drive shaft, 27 is a drive bearing, 28 is a vertical shaft, 29 is a plywood board that receives the leaf tobacco that is cut and falls backwards, 30 is a handle, and 31 and 31 degrees are tail wheels that can adjust the backward tilt angle. The supporting arm, 32 is the tire drive unit, 33 and the gong are the bearings, and 34 and 35 are the sprocket gears.

36 is a transmission belt, 37 is a leaf tobacco holder, 38 is a leaf tobacco, and 39 is a groove for hooking.

〔Effect of the invention〕

Since the present invention is configured as described above, it has the following features.

1 It is not a conventional unicycle style, but a four-wheeled vehicle style consisting of left and right running wheels and their tail wheels.The four wheels are located between the ridges and the bottom, so it can run extremely stably while straddling the ridges. , - There is no need for the operator to forcefully hold the aircraft in the correct cutting state as in the wheeled wheel style.

2. A linear guide mechanism consisting of two guide rods is installed at the front of the lower part of the tower frame, so the guide rods move forward while holding the thick stem base, and even if the operator releases the handle, the machine will continue to move in a straight line. The guide mechanism allows the machine to move straight, making the leaf tobacco reaper more stable and easier to operate.

3 Although the leaf tobacco reaper can run stably in this way, if the left and right running wheels are driven and connected in a normal state, it will be unable to run due to the presence of thick cut stalks.

6- In this regard, the present invention installs a tower-shaped machine frame upright, allows the cut residue to pass through the space in the shape of a tower, and inserts holes in the -1 part and the lower left and right sides of the tower-shaped machine frame. Since the left and right running wheels are interlocked by the provided upper and lower transmission shafts, it is possible to run without bumping into thick cut residues even if they exist.

4. A stem cutting guide mechanism is installed above the straight guide mechanism using a stem cutting device and a tower-shaped machine frame, so that the tobacco leaf that is tilted or about to fall is raised to the correct vertical position while being guided to the stem cutting device for cutting. This is an excellent leaf tobacco cutting machine that can perform the work well and reliably.
