Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a mud prevention device for a walking-type mobile agricultural machine.

This invention relates to a mud prevention device that prevents mud thrown up by wheels from adhering to rotating parts of various parts of an engine.

(Prior Art) In the conventional technology, the upper part of the wheel was protected from mud by a single plate-shaped fender.

(Problem that the invention aims to solve) Conventional fenders had a shape similar to a single flat plate, so when running between crops during management work, the fenders could damage the crops or cause the engine to be mounted and supported. The problem was that mud entered between the frame and the fender, causing mud to adhere to each rotating part of the engine.

(Means for Solving the Problem) This invention attempts to eliminate the drawbacks of the conventional device, and takes the following technical measures. That is, the wheels 4, 4 are mounted on the lower part of the transmission case 1 arranged in the vertical direction, and a frame body 2 with a flat upper surface is provided protruding forward at the front of the vertically intermediate part. Engine 3 is mounted on frame 2,
In a walk-behind mobile agricultural machine in which the sides of the engine 3 are covered with side covers 7 and 8, the lower edges of the side covers 7 and 8 extend laterally inward, respectively, to cover the upper parts of the wheels 4 and 4. It is characterized in that walls 5, 5 are provided, and the inner edges of the bottom walls 5, 5 are made to stand up on the side of the frame 2 and the rear edge to provide a front edge 24 and a rear edge 25. This is the structure of the anti-mud device for a walking-type mobile agricultural machine.

(Effects of the invention) This invention has the following technical effects due to the above configuration. That is, the lower edges of side covers 7 and 8 that cover the sides of the engine 3 are respectively extended inward in the lateral direction, and bottom wall portions 5 and 5 that cover above the wheels 4 and 4 are provided.
The inner edges of the bottom walls 5, 5 are brought into contact with the sides of the frame 2, and the front and rear ends of the bottom walls 5, 5 are raised to form a front edge 24 and a rear edge. Since the side edges 25 are provided, when the walking type mobile agricultural machine is moved forward or backward, the front edges 24 of the side covers 7, 8,
Alternatively, the rear edge 25 does not catch and damage crops. In addition, it is possible to prevent mud from entering the side covers 7 and 8, and when the side covers 7 and 8 are removed, the bottom walls 5 and 5, which correspond to conventional fender parts, are also removed at the same time. This means that the parts around the engine 3 can be inspected and adjusted easily.

(Example) The illustrated example shows a two-wheeled cultivator 9 incorporating this invention, with axles 10 on both left and right sides of the lower end.
A handle frame 11 is provided above the transmission case 1 from which the transmission case 10 is protruded, and a handle pipe 12 is attached to the handle frame 11.

This transmission case 1 is located in the middle part of the transmission case 1.
A frame body 2 whose upper surface is horizontal is provided so as to protrude in the direction of arrow A perpendicular to . In FIG. 3, the direction of arrow A is the front in the direction of travel, but when the handle frame 11 is reversed, it becomes the rear in the direction of travel. For convenience of explanation, the following description will be made with the direction of arrow A as the front.

An engine 3 is provided on the upper surface of the frame 2 so as to be freely adjustable in the longitudinal direction. An output pulley 13 is disposed on the left side of the engine 3, and is interlocked and connected to an input pulley 14 above the transmission case 1 by a power transmission device 15 such as a V-belt. The output pulley 13, the input pulley 14, and the power transmission device 15 are covered sideways, top and bottom, and front and rear with a left side cover 7 having a bottom wall 5 and a side wall 6 in the shape of a boat bottom.

The right side of the engine 3 is similarly covered with a right side cover 8 which has a nearly symmetrical shape.

FIG. 4 shows the tops of the left and right side covers 7, 8 cut out, and the inner edges of the bottom walls 5, 5 in the lateral direction are attached to the side surfaces of the frame 2 as shown in FIG. It is in contact.

At the front and rear ends of the bottom walls 5, 5 located above the wheels 4, 4, front edges 24, 24 and rear edges 25, 25, which stand up and are bent upward, are formed. .

Reference numerals 17 and 17 denote combined portions forming part of the front edges 24 and 24, and the combined portions 17 and 17 are configured to be in close contact with each other when the left and right side covers 7 and 8 are attached.

The wheels 4, 4 are located below the bottom wall portions 5, 5, which are shaped like the bottom of a boat, and the bottom wall portions 5, 5 function as fenders that cover the upper portions of the wheels 4, 4.

The left and right handle pipes 12, 12 are integrally connected to each other by a connecting shaft 18. Moreover, rotating pipes 19 and 20, which are double shafts, are attached to both sides of the connecting shaft 18, respectively, and by rotating the rotating pipes 19 and 20, the wires 21 and 20 are rotated.
22 is pulled. Engagement members (not shown) are provided at the tips of the wires 21 and 22,
The engagement is separated by rotating the rotary pipes 19 and 20.

The rotating pipe 19 is an operating tool for operating the upper and lower parts of the handle, and the rotating pipe 20 is an operating tool for reversing the entire handle back and forth.

According to the configuration of this embodiment, the side cover 7,
Since the bottom wall 5 of 8 is shaped like the bottom of a ship, even when the plant moves through the crops during management work, the crops are guided along the bottom surface of the ship, making it difficult to damage the crops.
