Description

[Detailed explanation of the invention] (Field of industrial application) This invention is installed on a paddy field vehicle that can travel through flooded rice fields, a boat, etc., and uses a cutting rotor to cut stems and leaves growing in soft soil. This invention relates to a device for cutting leaves and stems for use in flooded paddy fields.

(Problems to be solved by the invention) For example, lotus root is a plant that grows in flooded rice fields with soft soil. Lotus roots have long stems (long stalks) that extend above the ground from their joints and have leaves attached to them. (Hereinafter, these stems and leaves will be referred to as stems and leaves.) Methods for digging up lotus roots growing underground include manual digging using a hoe, and methods of fluidizing the soil around the lotus roots with a jet of water and causing the lotus roots to float. Regardless of which method is used, it is difficult to perform digging work unless the above-mentioned stems and leaves are harvested.

Therefore, before digging up lotus roots, the stems and leaves are usually harvested and removed from the field.

One possible method for harvesting the stems and leaves is to attach a weeding machine such as an existing rotary cultivator to a tractor, but in flooded paddy fields with soft soil, the tractor may sink under its own weight and become unable to drive. Unable to perform work. Also,
It is conceivable that the weeding machine could be attached to a paddy field vehicle equipped with a lightweight and buoyant traveling device to enable it to travel through flooded paddy fields with soft soil, or a boat that floats on the water surface. Boats are lightweight and buoyant, so they tend to lose their balance, and when a weeding machine is attached, the balance is lost and it is difficult to maintain a stable posture, which is dangerous. It is used to pull out, bury, and cut roots of stems and leaves; it does not have a cutting function, and unless the pulled stems and leaves are carried out of the field, they will become a hindrance to subsequent work.

As described above, conventionally, there has been no suitable reaping device for reaping the leaves and stems growing in flooded paddy fields with soft soil without interfering with subsequent work.

Conventionally, the cutting and removal of stems and leaves was done by hand using a hook and then carried and removed by hand, which required considerable hard labor, even though the fields were flooded with soft soil that was difficult to walk on.

This invention is designed for use with rice field vehicles that tend to lose their balance.
To provide a foliage cutting device for flooded paddy fields capable of harvesting foliage while maintaining a stable posture without losing its balance even when mounted on a boat, etc., and capable of cutting the harvested foliage so as not to interfere with post-work. The purpose is to

(Means for Solving the Problem) In order to achieve this objective, the present invention uses a paddy field vehicle that can move through flooded paddy fields with soft soil, or a rotary body that is attached to a floating boat on the water surface and rotates. In a reaping device for reaping the stems and leaves growing in a paddy field, a reaping rotor 14 connected to a drive shaft is connected to a hollow cylindrical rotor 12 having buoyancy and a large number of cutting blades 13...
The cutting blade 1 is constructed by planting the
A fixed blade mounting rod 16 with fixed blades 17 attached thereto is disposed at a relative position to the cutting blades 13 on the outer periphery of the rotation locus of No. 3.

(Function) As described above, by making the rotating body 12 of the reaping rotary body 14 of the reaping device B have a hollow cylindrical floating structure having buoyancy, buoyancy is generated in the reaping device B itself, such as a paddy field vehicle, a boat, etc. Even if the reaping device B is attached to the reaping device B, the reaping device B can support its own weight by the buoyancy generated by itself, so that the stable posture of the paddy field vehicle, boat, etc. can be maintained without losing the balance.

Further, a fixed blade attachment rod 16 is disposed on the outer periphery of the rotation locus of the cutting blade 13 of the reaping rotary body 14, and a fixed blade 17 is provided on the fixed blade attachment rod 16 at a position facing the cutting blade 13 of the reaping rotary body 14. Since ... is installed, the cutting blade 13
The cutting action by the fixed blade 17 is obtained, and the cutting blade 13
You can shred the harvested vines.

(Example) An example of the present invention will be explained with reference to the drawings.
A shows a running vehicle for paddy fields, in which a prime mover 2 is mounted on the upper surface of a machine base 1, a transmission case 3 is provided on the lower surface, and a hollow cylindrical floating body 4 having buoyancy is mounted on the lower surface of the machine base 1. A plurality of floating bodies 4 are arranged and supported on both the left and right sides with their axes perpendicular to the direction of movement of the aircraft, and a pair of left and right floating bodies 4 are connected to the prime mover 2 via the transmission case 3, and the left and right floating bodies 4... It is constructed by extending a wide endless track belt 5 having numerous protrusions around it, and 6 is a support column erected at the front central part of the machine stand 1 for mounting the work machine.

B shows a stem and leaf cutting device according to the present invention, 7 is a support arm, 8 is a connecting rod that hangs down from both ends of the support arm 7 and is fixed, and a base 9 is fixed to the lower end of these connecting rods 8. This constitutes the machine frame of the stem and leaf reaping device B, and on one side of the base 9, a vertically elongated transmission case 10 is disposed vertically so as to be divided into upper and lower halves by the base 9, and is interposed therein. prime mover 1 on the other side
1 is mounted, and the output shaft of the prime mover 11 and the input shaft at the upper part of the transmission case 10 are connected by a pulley and belt mechanism. A reaping rotary body 14 having a number of cutting blades 13 implanted around the rotary body 12 is connected to the rotary body 12. and,
A cutting blade 13 is parallel to the rotating body 12 and is embedded in the rotating body 12 on a support rod 15 protruding from one end of the base 9.
A fixed blade mounting rod 16 placed facing the outer periphery of the rotating locus is fixed, and a fixed blade 17 is attached to the fixed blade mounting rod 16 at a position facing the cutting blade 13 installed on the rotating body 12. , the cutting action is performed together with the fixed blade 17 by the rotation of the cutting blade 13.

In addition, 18 in the figure is a cover attached to the fixed blade 16 to cover the reaping rotary body 14.

Reference numeral 19 denotes a mounting bracket that extends from one end of the support arm 7 of the frame of the foliage harvesting device B and is fixed to the frame, and the middle part of the mounting bracket 19 is attached to the upper end of the support column 6 of the paddy field vehicle A with a shaft that can freely move up and down. The tip of the mounting bracket 19 and a protrusion provided on the lower rear surface of the support column 6 are connected and supported by a hydraulic cylinder 20. The hydraulic cylinder 20 is connected to the paddy field vehicle A via an electromagnetic switching valve 21.
