Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a tobacco residue harvester.

111u1 (Traditionally, the disposal of tobacco residue has been regarded as important in practice, but in recent years, especially from the perspective of disease prevention, emphasis has been placed on completely removing tobacco residue without leaving it in the workplace. Ta.

Moreover, as the shortage of compost raw materials has become a problem, it has become desirable to transport them to another location and reuse them there as compost raw materials.

By doing so, the aim is to prevent fatigue in the workplace and to make effective use of waste materials.

Therefore, conventionally, the base part of the remaining tobacco trunk was cut off.
The upper part of the remaining tobacco trunk was removed from the workshop, but the root part was left alone.

However, it has been found that if the root part of the remaining tobacco trunk is left in the workplace as in the past, the root part will have a negative impact on the workplace.

λ1B Ikitsuki”! Therefore, in view of the above-mentioned prior art, the present invention has been devised to remove all tobacco residue including the root part of the tobacco residue, thereby making it possible to more completely dispose of the tobacco residue. The purpose is to provide stem harvesters.

11 11 In order to achieve the above-mentioned object, the present invention provides a tobacco residue harvesting system in which a pair of gluing rollers are provided on both sides of a frame so as to straddle one ridge, and in order from the front of the frame to the rear. The gist of this tobacco residue harvester is a structure in which a screw-type root extractor, a conveyor, a soil remover, a feed roller, and a cutter are arranged to perform root removal, soil removal, and cutting in succession.

In this invention, from the front to the rear of the frame of the tobacco residue harvester, a screw-type root extractor, a conveyor,
Place the soil dropper, feeder D-ra, and cutter. As a result, root removal, soil removal, and cutting of remaining tobacco trunks were carried out continuously.

- A crawler is used on the undercarriage of the harvester to ensure stable work with little slippage even on soft ground. Since it is a self-propelled system using rollers, it has a great practical effect of being able to turn around easily and being able to be used in various workplaces. Furthermore, the screw-type root puller is placed in front of the frame, making operating the harvester extremely easy. Also, since it uses a screw-type root extractor, root breakage can be avoided. This is extremely effective in the sense of more completely removing the remaining tobacco root portion from the workplace.

In addition to simply pulling out the remaining tobacco trunks, they are also cut with a cutter at the rear of the frame, so they can be used as raw materials for compost.

In addition, since it uses a screw-type root extractor, it is #! Even if there are only a few weeds in the field, the roots can be removed very effectively.

Support 1 craftsman A screw type root extractor 2 is provided at the front part of the frame 1.

The vertical position of this screw-type root extractor 2 can be adjusted in the vertical direction by an adjusting means 3.

A conveyor 4 is arranged at a slight inclination following the screw type root extractor 2. As illustrated in FIG. 2, this conveyor 4 has a pair of chains 5.6 arranged endlessly on both sides, and a large number of bars 7 are arranged at predetermined intervals between the chains 5.6. It is arranged by each. Further, each chain 5.6 is rotatably driven in a predetermined direction by a sprocket.

A pair of presser rows 58.9 is provided above the conveyor 4. These presser rollers 8.9 are rotatably arranged at both ends of the swing arm 10, respectively. Swing arm 10
is capable of swinging around a fulcrum 11.

A soil dropper 12 is arranged at the upper end of the conveyor 4. The soil dropper 12 is constructed by, for example, a plurality of rods 15 arranged in a drum shape at regular intervals between a pair of disks 13 and 14.

When the soil remover 12 is rotated in a predetermined direction, the round rods 15 strike the root portion of the remaining tobacco trunk, and at this time the soil is removed.

Following the soil dropper 12, a feed row 517, 18 is arranged. The lower feed roller 17 is arranged at a predetermined position and rotates at that position, and the upper feed roller 18 not only rotates but also can move vertically. The upper roller 18 is not forcibly moved in the vertical direction, but is biased downward by its own weight, and when a tobacco residue arrives there, it is fed by the thickness of the tobacco residue passing through. It is designed to be able to move slightly upward against the weight of the roller 18.

A cutter 20 is arranged immediately after the feed rollers 17,18. This cutter 20 is entirely covered with a drum-shaped casing 21, and a rotating shaft 22 is disposed inside the casing 21. As shown clearly in FIG. Rotary plates 23, 24 are respectively fixed near both ends, and movable blades 25 are respectively fixed to both ends of these rotating plates 23, 24. A scraping blade 26 is provided adjacent to the movable blade 25. Further, a fixed blade 28 that functions as a receiving blade is fixed to the casing 21 in correspondence with the movable blade 25. The fixed blade 28 is arranged at the diagonally downward entrance of the casing 21, adjacent to the aforementioned feed rollers 17,18.

In addition, a discharge passage 29 is located diagonally above the casing 21.
The remaining stem cuttings scraped up by the scraping blades 26 are scraped up into the discharge passage 29.

A guide 3° is arranged connected to the outlet of the discharge passage 29. This guide 30 is approximately box-shaped and has an open upper part, which is connected to the discharge passage 29.
The receptacle is designed to receive the remaining cut material coming from the discharge path 29.

As shown in FIG. 5, a damper 31 is arranged in the middle of the guide 30, and two outlets 32 and 33 branch from the damper 31. This damper 31
has its lower end fixed to a rotating shaft 36, and the rotating shaft 3
One end of the guide 30 protrudes outside the guide 30, and a lever (not shown) is fixed to one end of the rotating shaft 34. By operating the lever, the damper 31 can be switched in any direction. It looks like this.

On the other hand, each of the two outlets 32 and 33 has a bag 34.
I! -It is designed to be removable. It is preferable that these bags 34 be made into net bags so that it is possible to check how much of the remaining cut material is inside.

Note that the engine, transmission mechanism, hydraulic motor, hydraulic system, etc. can be conventional ones, and therefore their explanations will be omitted.

The operation of the tobacco residue harvester described above will be explained.

First, check the situation at the work site and adjust the screw type root extractor 2 to the desired vertical position. After that, start the engine of the harvester and remove the screw type root extractor 2, conveyor 4, soil remover 12, feed rollers 17 and 18, and cutter 2.
Activate 0. Next, the screw-type root extractor 2 is set in the ridge where the remaining tobacco trunk is located.

Then, the harvester runs between the ridges, straddling the remaining trunks. At this time, the screw-type root extractor 2 bites into the root part of the remaining tobacco trunk in the soil.

The root portion of the remaining tobacco trunk is caught in the screw extractor 2 and drawn toward the conveyor 4. Thereby,
At the same time as the tobacco residue falls down, it is forcibly conveyed diagonally upward by the conveyor 4. At that time, presser roller 8.9
In addition to holding down Tobacco Zankan, he also performs some dohyo-wari.

The remaining tobacco trunks are further sent out by the conveyor 4 toward the soil remover 12. There, the soil remover 12 knocks and removes the soil from the remaining tobacco trunks, especially at the root part. It is sent backward by the feed rollers 17 and 18 and arrives at the cutter 20. Then, the tobacco residue is cut at predetermined intervals by the movable blade 25 and the fixed blade 28. For example, the cutting length is about 2711 mm. Make it.

Such cutting (i.e. chopping) is performed,
Cutting tobacco remains are generated.

Such cut tobacco residues are vigorously raked upward by the raking blades 26. It is then discharged into the guide 30 through the discharge passage 29. After that, a course is selected in a desired direction by the damper 31, and the damper 3
1 and is guided to the outlet 33 or 32 opened by 1 and stored in one bag 34.

When the tobacco residue cut pieces stored in the bag 34 reach a predetermined amount in this way, the damper 31 is switched to allow the cut tobacco residue to enter the other bag 34. And the other bag 34
While storing the cut tobacco residue in the bag 34, the full bag 34 is closed and removed from the outlet 32, and an empty bag 34 is placed there again. These operations are performed alternately while the harvester is running.
