Description

[Detailed description of the invention] The present invention is mainly a cover structure for a mobile agricultural machine that covers the upper part of a rotary tillage device such as a management machine used in a relatively small space such as a home garden. The extension cover is configured to be able to be attached and detached from the permanent cover by fixedly connecting and disconnecting the downward extending portion of the outer end of the permanent cover and a bracket provided on the extension cover side corresponding thereto. The present invention relates to cover structures for mobile agricultural machinery.

In the above-mentioned management machines, depending on the size or shape of the field, an extended rotary tilling device may be attached to the rotary tilling device. Claw 9
An extension cover 3' that covers the upper part of b' is attached to the permanent cover 2', but due to manufacturing errors or distortions and deformations that occur with use, gaps often occur at the seam c' between the two covers. However, there were drawbacks such as the dirt thrown up by the rotary tiller scattering upward from the gap and covering the operator with the dirt.

In view of the above circumstances, the present invention provides a cover structure for a mobile agricultural machine that prevents earth and sand from scattering upward from the joints of the cover even if there are some manufacturing errors or distortions caused by use. has a purpose.

A characteristic configuration of the cover structure for a mobile agricultural machine according to the present invention, which has been made to achieve the above object, is that the bracket is attached to a position closer to the outer end than the inner edge of the extension cover, and The extension cover is configured to be attached to the permanent cover with the inwardly projecting cover portion overlapping the permanent cover.

The effects of the present invention having such a characteristic configuration are as follows.

In other words, since the bracket that contacts the downwardly extending portion is attached at a position closer to the outer end than the inner edge of the extension cover, in the connected and fixed state where the downwardly extending portion and the bracket are in contact with each other, The part of the cover that protrudes inward from the bracket of the extension cover overlaps the top surface of the permanent cover.
Due to the presence of the overlapping part, even if some manufacturing errors or distortion deformation due to use occur, no vertically penetrating gap will be created at the seam of both covers, and dirt, etc. will be scattered above the cover. can be reliably prevented.

Further, as a means for forming the polymerized portion, an eighth
As shown in the figure, a method has also been considered in which a bracket 5' is formed at a position closer to the inner end than the outer edge of the permanent cover 2', and is fixed by coming into contact with the downwardly extending portion of the inner edge of the extension cover 3'. However, in that case, when removing the extension cover 3' and working with only the permanent cover 2', an edge 2 is attached to the extending end of the permanent cover.
6' may occur, and the operator may be injured by the edge 26'. Moreover, the edge 26' may be deformed due to collision with another object, causing a gap due to the deformation of the overlapping portion 27' when installing the extension cover 3'. However, with this invention, even when the extension cover is removed, such edges do not occur on the edge of the permanent cover, improving safety and scattering the dirt upward. The prevention of scattering can be achieved.

Next, an embodiment of the configuration of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, rotary tillers 9, 9 are rotatably attached to the left and right sides of a transmission case 8 attached to a frame 7, and an engine E is mounted above the frame 7 to operate the machine body. 1, and has a control handle 10 extending rearward and upward to form a management machine.

Further, in the figure, reference numerals 2 and 2 denote permanent covers that are always attached to the frame 7, and permanent rotary tilling claws 9a, which extend left and right from the transmission case 8.
9a, and 3, 3 is an extension cover that is attached to the permanent covers 2, 2, and is further extended to the left and right of the permanent rotary tilling claws 9a, 9a as necessary. It covers the upper part of the extended rotary tilling claws 9b, 9b.

In order to attach and fix the extension covers 3, 3 to the permanent covers 2, 2, as shown in FIGS. A reinforcing member b is fixed in contact with the protruding portions 4, 4, and a nut 12 is fixed to the reinforcing member b.
A bracket 5 is fixed to the back side at a position closer to the outer end than the inner edge, and the bracket 5 and the downwardly extending portion 4 are connected and fixed with bolts 13 and nuts 12 while in contact with each other. The cover portion 6 of the extension cover 3, which projects inwardly from the bracket 5, overlaps the upper surface of the permanent cover 2.

Further, the control handle 10 is shown in FIGS. 5 and 6.
As shown in the figure, the vertical axis P is relative to the fixed seat 15 attached to the fixed rod 14 extending from the machine body
It is attached to a swinging member 16 that can swing freely around the three holes 17 formed in the fixed seat 15.
A bolt 19 is inserted from the back side into the elongated hole 18 including..., and the nut 2 to which the bolt 19 is screwed is inserted.
0 is fixed to the swinging member 16, and the bolt 1
By adjusting the rotation of the operating handle 21 by nine turns, the operating handle 10 is brought into a state in which the large diameter portion 22 of the bolt 19 has come out of the hole 17 and can be swung around the vertical axis P, and the large diameter portion 22 is in the above-mentioned state. It is configured to be switchable between a fixed state in which it is selectively fitted into the holes 17.

Further, a chrysanthemum seat 23 is formed on the contact surface between the operating handle 10 and the swinging member 16, and the operating handle 10 can be moved up and down by loosening the tightening handle 24 and releasing the tightening handle 24. It is constructed so that it can be fixed by tightening after adjusting the swing.
