Description

[Detailed description of the invention] The invention is based on a cutter (or chipper) mounted on a vehicle body that can freely run and move using running wheels.
This invention relates to improvements to a self-propelled agricultural cutter that is driven by an engine mounted on the vehicle body.

In order to improve the running performance of the self-propelled agricultural cutter to move to the desired location,
It is required to make the vehicle body as small as possible. However, in order to meet this demand, the cutter mounted on the car body and the engine that drives it were placed in a limited space on the top of the car body with less protrusion from the car body to all four circumferences. If the car body is assembled and supported, it will be inconvenient to feed the material to be cut to the cutter when the car body is placed in a predetermined location and the cutter is driven to perform cutting work, and it will also be difficult to start the work. In addition, since the engine and the cutter are placed close to each other, there is a problem in that it is inconvenient to supply fuel oil to the engine installed in the engine prior to the cutter. A problem arises in which a large amount of dust particles etc. are covered.

The present invention solves these problems by arranging the cutter and the engine so that the amount of lateral protrusion thereof is reduced and placing the cutter and engine on the top of the vehicle body, while supplying the material to be cut to the cutter. The object of the present invention is to provide a means for configuring a self-propelled agricultural cutter so that the engine can be easily refueled and the engine can be effectively dust-proofed.

In this invention, for this purpose,
A handle rod 2 for performing steering operation is installed at the rear of a vehicle body 1 that freely travels by running wheels 10, 10, and a cutter body that houses a cutting mechanism of a cutter 3 on the front end side of the upper surface of the vehicle body 1. 30 is mounted with its supply port facing rearward, and a supply gutter 31 that protrudes rearward is connected to the supply port of the cutter body 30, and the rear end 3 of the supply gutter 31 is connected to the feed port of the cutter body 30.
1a, the front end side of a horizontally wide guide plate 4 for guiding the material to be cut into the supply gutter 31 is rotatably connected vertically, and the rear end side of the guide plate 4 is connected to the above-mentioned guide plate 1a. The engine 5 is mounted on the rear end side of the upper surface of the vehicle body 1 below the guide plate 4 and the supply gutter 31, and is supported on the handle rod 2 so as to be able to move in and out. This paper proposes a means of constructing a self-propelled agricultural cutter by mounting it on a frame.

Next, an example of implementation will be described in detail with reference to the drawings.

In Fig. 1, 1 is the body of a self-propelled agricultural cutter A, with running wheels 10, 10 mounted on the right and left sides of the front end side (right end side in Fig. 1), and running wheels 10, 10 mounted on the left and right central parts of the rear end side. A guide wheel 11, which is a free wheel, is pivotally supported.

Reference numeral 2 denotes a handle rod installed at the rear end of the vehicle body 1, and the upper end portions of shaft rod-shaped stays 20 raised from both left and right ends of the rear end of the vehicle body 1 are bent rearward. , by installing the grip portions 22 at the rear end of the rear bent portion 21, the grip portions 22 are installed so as to face each other in a pair on the left and right with an interval corresponding to the width of the left and right sides of the vehicle body 1, as shown in FIG. It has been done.

Reference numeral 30 denotes the main body of the cutter 3 (or chipper) mounted on the front end side of the vehicle body 1, which is formed in the shape of a machine casing, and has a cutting mechanism (or crushing mechanism) accommodated therein. This is a conventionally known type in which a chamber (or crushing chamber) is formed, and a supply port for supplying material to be cut to the cutting chamber is provided at the upper part of the rear end side, and a cutting chamber is provided at the front side. This is a normal type equipped with a discharge gutter 32 for discharging the material cut to the front, and is mounted on the vehicle body 1 with its supply port facing toward the rear of the vehicle body 1. be. A supply gutter 31 for supplying the material to be cut is connected to the supply port of the cutter body 30 so as to protrude rearward from the supply port. The rearward protrusion length of the supply gutter 31 is such that the rear end 31a of the feed gutter 31 is located approximately in the middle of the space formed between the cutter body 30 and the handle rod 2 described above. It is set to .

Reference numeral 4 denotes a guide plate whose front end is pivotally connected to the rear end 31a of the supply gutter 31 via a connecting shaft 40 so as to be rotatable up and down, and is formed wide from side to side as shown in FIG. The rear end side is made somewhat wider than the spacing between the left and right handle bars 2, 2, and the widened rear end side is used as the left and right handle bars 2, 2.
By mounting and supporting the upper surface of each of the rear bent portions 21 of 2, as shown in FIG. The upper part of the rear end side of the vehicle body 1 is closed off between
The supply gutter 31 is held in a downwardly inclined position toward the rear end 31a of the supply gutter 31 from the rear. In addition, at the portions of the left and right ends of the rear end of the guide plate 4 that are joined to the upper surface of the rear bent portion 21 of the handle bar 2, the upper surface of the rear bent portion 21 is attached as shown in FIG. A fitting part 41 that fits on the side is formed. A locking tool may be detachably provided between the fitting portion 41 and the rear bent portion 21.

Reference numeral 5 denotes an engine that drives a cutting mechanism installed inside the cutter body 30, and is connected to the aforementioned supply gutter 31.
It is mounted on the rear end side of the upper surface of the vehicle body 1 below the guide plate 4, at a position closer to one of the left and right sides.
The engine 5 is connected to the cutter body 3 via a transmission mechanism 6 provided on the other side of the rear end of the vehicle body 1.
The input shaft of the cutting mechanism in 0 and the aforementioned running wheel 10,
It is conducted to 10 axles.

The self-propelled agricultural cutter according to the present invention constructed as described above operates as follows.

A supply gutter 31 protrudes from a cutter body 30 mounted on the front end of the vehicle body 1 toward the rear end of the vehicle body 1.
Since the engine 5 is located on the rear end side of the vehicle body 1 below the supply gutter 31, the cutter 3 and the engine 5 are mounted on the vehicle body 1 with a significantly reduced amount of lateral protrusion from the vehicle body 1. That will happen.

Further, when cutting work is performed by driving a cutter mounted on the vehicle body 1, the worker stands behind the rear end of the vehicle body 1 and moves backward from the cutter body 30 mounted on the front end of the vehicle body 1. For the protruding supply gutter 31, a guide plate 4 is provided to span between the rear end 31a of the supply gutter 31 and the handlebar 2 mounted on the rear end of the vehicle body 1. By supplying the material to be cut using the upper surface, workability can be improved.

The supply gutter 31 and the guide plate 4 cover the upper part of the engine 5 mounted on the vehicle body 1, so that the engine 5 is covered with debris from the material to be cut that is generated during the work. will be prevented.

Furthermore, by rotating the rear end side of the guide plate 4 up and down, the guide plate 4 can be folded along the rear side of the supply gutter 31 as shown by the chain line in FIG. Since the upper part of the engine 5 mounted on the end side is left open, the engine 5
The restrictions on refueling work will be released.

Therefore, according to the means of the present invention, by mounting the cutter 3 and the engine 5 on the vehicle body 1 with a small amount of overhang to the four circumferences, the cutting work by the cutter 3 and the engine 5 can be performed while improving running performance. To provide a self-propelled agricultural cutter which can easily perform refueling work and can effectively prevent the engine 5 from being covered with debris from the material to be cut.
