[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for precisely cutting foliage of root vegetables, which contributes to labor saving in harvesting root vegetables such as carrots and radish.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. Mostly manual. Although some harvesting machines have been introduced, the cutting of foliage is done at a fruit sorting facility, which has a low work efficiency and is used in combination with manual recutting.

[0003]

The problems described in the prior art have the following problems. Manual work required a lot of labor. In the case of mechanical harvesting, the shoulders of root vegetables were scratched, so much labor was required to cut and repair the foliage.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows. That is, the thing of this application WHEREIN: The diagonal conveyor part 3 arrange | positioned in the front surface of the machine body 2 toward the advancing direction of the said machine body, and the horizontal direction provided in parallel with the advancing direction of the machine body above the machine body 2 and horizontally. The starting end of the two-stage conveyor unit 4 is connected in a state of approaching the lower surface near the end of the skew conveyor unit 3, and the horizontal two-stage conveyor unit 4 includes an upper horizontal conveyor 5 and a lower surface of the upper horizontal conveyor. And a cutter blade 8 arranged in a horizontal state so as to approach a terminal end of the lower horizontal conveyor 6 and a lower horizontal conveyor 6 provided near the lower horizontal conveyor 6. .

In this case, the supporting height of the cutter blade can be located substantially at the center of the thickness of the left and right rear pulleys of the lower horizontal conveyor 6. Also,
A soft sponge-like body may be attached to the outer peripheral surfaces of the V-belts used for the upper horizontal conveyor 5 and the lower horizontal conveyor 6. Further, the speed of the V-belt in the skew conveyor unit and the speed of the V-belt in the horizontal two-stage conveyor unit can be configured so that the speed of the V-belt in the horizontal two-stage conveyor unit is slow.

Is a precision cutting device for foliage of root vegetables of the present invention.
2 is a well-known airframe provided in a harvesting machine such as a well-known self-propelled bagger type, self-propelled tanker type, or a direct-equipped container type, which connects pillars 2A arranged at the four corners with the upper parts of these pillars. It is composed of a horizontal rail 2B.

Reference numeral 3 denotes a skew conveyor section which is arranged on the front surface of the machine body in the traveling direction of the machine body, and a known lifter (not shown) is provided at the lower end of the skew conveyor section. Therefore, the skew conveyor unit 3 includes the left and right front pulleys (not shown), the left and right rear pulleys (not shown), and the left and right V belts 3 hung on the pulleys in a pair.
It is composed of A and 3B.

Reference numeral 4 denotes a horizontal two-stage conveyor section provided above the machine body 2 in parallel with the traveling direction of the machine body and horizontally. The starting end of the horizontal two-stage conveyor section 4 is the skew conveyor section 3. It is connected in the state of approaching the lower surface near the terminal end. Therefore, the horizontal two-stage conveyor unit 4 is composed of an upper stage horizontal conveyor 5 and a lower stage horizontal conveyor 6 provided close to the lower surface of the upper stage horizontal conveyor.

Therefore, the upper horizontal conveyor 5 includes left and right front pulleys 5A and 5B and left and right rear pulleys 5A1 and 5B.
1 and left and right V-belts 5A2 and 5B2 that are hung on these pulleys in a pair. In this case, soft sponge-like bodies 5A21 and 5B21 are attached to the outer peripheral surfaces of the V belts 5A2 and 5B2.

The lower horizontal conveyor 6 includes left and right front pulleys 6A and 6B and left and right rear pulleys 6A1 and 6B1.
And the left and right Vs hung on these pulleys in a pair
It is composed of belts 6A2 and 6B2. In this case, soft sponge-like bodies 6A21 and 6B21 are attached to the outer peripheral surfaces of the V belts 6A2 and 6B2.

The length of the upper horizontal conveyor 5 in the front-rear direction is longer than the length of the lower horizontal conveyor 6 in the front-rear direction. The rear portion of the upper horizontal conveyor 5 is located rearward of the end portion of the lower horizontal conveyor 6. It is configured in an extended state. Each pulley is a bracket 2C connected to the machine body
Supported by. M is a motor that drives each pulley. It should be noted that the speed of the V-belt of the skew conveyor unit and the speed of the V-belt of the horizontal two-stage conveyor unit are the horizontal two by the difference in angle between the skew conveyor unit and the horizontal two-stage conveyor unit.
The speed of the V-belt in the multi-stage conveyor unit is slowed.

Reference numeral 7 denotes a tension roller section, which is composed of a left tension roller 7A and a right tension roller 7B. The left tension roller 7A is located on the left side of the upper horizontal conveyor 5 of the horizontal two-stage conveyor section 4. V belt 5
A2 and the left V-belt 6A2 on the lower horizontal conveyor 6
And the right tension roller 7B moves inwardly with respect to the right V-belt 5B2 of the upper horizontal conveyor 5 of the horizontal two-stage conveyor unit 4 and the right V-belt 6B2 of the lower horizontal conveyor 6 of the horizontal two-stage conveyor unit 4. It is intended to act on people.

Therefore, the left tension roller 7A is
Vertical axis 7A standing on bracket 2D extending from the machine
1, the front and rear arms 7A2 supported by springs so as to always act inwardly about the vertical axis, and the front and rear rollers 7 rotatably supported vertically at the tips of the front and rear arms.
It is composed of A3 and 7A4. The right tension roller 7B includes a vertical axis 7B1 standing upright on a bracket 2D extending from the machine body, front and rear arms 7B2 supported by springs so as to always act inwardly about the vertical axis, and the front and rear arms 7B2. The front and rear rollers 7B3 and 7B4 are rotatably supported by the tip of the arm in a vertical state.

Reference numeral 8 denotes a cutter blade which is disposed horizontally in a state of approaching the end portion of the lower horizontal conveyor 6, and in this case, the supporting height of the cutter blade is such that the left and right rear pulleys 6A1 and 6B1 of the lower horizontal conveyor 6 are supported. It is desirable that the rear pulley is located substantially at the center of the thickness of the rear pulley. 8A is a motor for rotating the cutter blade.

The present invention operates as follows. 1. The carrot 9 is dug up by a lifter provided at the end of the skew conveyor section, sandwiched by the facing V-belts, and sent to the upper part of the machine body. 2. The carrot 9 sent to the upper part of the fuselage is sandwiched by a horizontal two-stage conveyor section and sent to the rear.
Since the soft sponge-like body is attached to the outer peripheral surface of the belt, the foliage 9B can be reliably held. Then, in this case, the shoulder portion 9A of the carrot 9 is aligned with the lower surface of the lower horizontal conveyor 6 by being pulled upward by the difference in angle between the skew conveyor section and the horizontal two-stage conveyor section. Of course,
At this time, the speed of the V-belt is slower in the V-belt in the horizontal two-stage conveyor section than in the V-belt in the skew conveyor section. 3. There is a cutter blade behind the cutting position of the foliage 9B set by the upper horizontal conveyor, and the foliage 9B is cut by this cutter blade.

[0017]

Since the present invention is constructed as described above, it has the following effects. Since the foliage can be precisely cut at the field stage, labor-saving mechanization becomes possible.
