Description

[Detailed explanation of the invention] In general, a mobile threshing machine has a threshing device removably mounted on a machine base with a traveling device, so the threshing device can be lowered and used as a transport machine. Since the main purpose of use is threshing, and the annual usage time is short, it is most desirable that the machine be small, lightweight, and inexpensive.

However, the conventional mobile threshing machine was first introduced in 1973.
As seen in Publication No. 57971, etc., the control handle was attached to the machine base between the threshing device and the engine, so it was necessary to provide a wide space between the threshing device and the engine to allow the control handle to stand up. Therefore, the length of the aircraft becomes large, and
The drawbacks were that the control handle became longer and had to be reinforced, making the aircraft larger and more expensive.

The purpose of the present invention is to improve the above-mentioned drawbacks, and the present invention has a threshing device mounted on the front part of a machine base having a traveling device, and a supply port of the threshing machine located at the rear end of the machine base. On the side, an operation panel consisting of at least a side plate and a rear wall and supporting an operation lever is installed upright, an engine is mounted close to the front of the operation panel, and a control panel is mounted on the rear of the operation panel. The present invention is characterized in that a handle is attached, and an engine cover housing the engine therein extends from the operation panel so that the operation panel becomes a part of the engine cover and also serves as a support member for the handle.

The embodiment shown in the drawings will be explained below.1
is a machine base having a traveling device 2, with an operation panel 3 erected at its rear end, and an engine 4 mounted on the engine base with a fuel tank 5 brought close enough to touch the front surface of the operation panel 3. Machine 1 via 4a
A self-threshing type threshing device 6 is mounted in front of the engine 4 of the machine 1.

Further, the engine 4 drives the traveling device 2 via the transmission case 7 with its output pulley 4b, and also drives the input pulley 9 mounted within the machine width of the threshing input shaft 8 via the belt 10, as shown in FIG. Since the threshing device 6 is driven by the movable threshing machine, the transmission device of the threshing device 6 does not protrude outward and the width of the machine increases unlike in conventional mobile threshing machines, and there is no need for a safety cover.

The threshing device 6 is provided with a swing sorting body 15 which is installed in a sorting air path extending from below the handling room receiving net 11 to the suction windmill 12 and facing onto the first receiving gutter 13 and the second receiving gutter 14, A flow plate 16 at the starting end of the oscillating sorting body 15 is connected to a fixed flow plate 18 via a rubber plate 17, and the air cleaner 1 of the engine 4
9 and the muffler 20 are fitted into the space formed below the fixed flow plate 18 and the flow plate 16 of the threshing device 6, so the engine 4 and the threshing device 6
The two were fitted into each other, and the length of the two joined together was shorter than the sum of their individual lengths.

Further, the engine cover 22 of the engine 4 is a rear plate 22a extending from the rear end of the right side of the operation panel 3 to the right side.
and the right end of the rear plate 22a and the machine base 1 on that side.
Right side plate 22 extending from the rear end to the side wall of the threshing device 6
b, a left side plate 22c extending from the front end of the left side of the operation panel 3 to the side wall of the threshing device 6; It consists of a non-perforated top plate 22d whose rear part is screwed onto the operation panel 3.
Since the non-perforated top plate 22d covers the entire upper surface of the engine room, even though the stock base of the grain culm, which has a large amount of straw debris attached to it, passes over it and the straw debris falls, it does not The right side plate 22b and the left side plate 22 are prevented from falling into the engine room.
The lower part of c was screwed to the receiver 22e on the machine base 1, the left side of the rear plate 22a was screwed to the side of the operation panel 3, and the right side was screwed to the rear end of the right side plate 22b.
The entire engine cover 22 is integrated with the threshing device 6 and the operation panel 3.

A support arm 23 protruding from the operation panel 3
Since both ends of the control handle 24 are fixed to the receiving plate 23c, which is the part where the support plate 23b is welded to the support plate 23b installed upright on the machine stand 1, and to the rear surface of the operation panel 3, the operation handle 24 is fixed to the rear surface of the operation panel 3. There is no need to provide a space between the engine 4 and the threshing device 6 in order to fix the control handle 24 to the machine base 1.

Further, as shown in FIG. 6, a pair of left and right side clutch levers 26 and a travel clutch lever 27 are pivotally supported on a support shaft 25 supported on the operation panel 3.
6 and 27 have operating wires 26' and 2, respectively.
7' rear end is connected, and as a result, the operation panel 3
will be stored in the engine room.

Furthermore, the starter rope 28 of the engine 4 passes between the operating wires 26' and 26' and between the side clutch levers 26 and 26, and is connected to a grip part 29 attached to the operating panel 3 so as to be movable back and forth. Therefore, the starter rope and its grip do not get in the way unlike in the conventional case.

Furthermore, a pair of left and right brackets 31, 31 for supporting the self-disengaging clutch lever 30 is provided at the front of the operation panel 3 on the machine base 1, and the throttle of the engine 4 is inserted between these brackets 31, 31. The control wire 32 to be adjusted is held through the operating wire 27' of the traveling clutch lever 27, and the control wire 3 is connected to the control lever 33 provided on the side of the operating panel 3.
The two rear ends are connected.

In addition, in the drawing, 34 is a grain lifting machine, 35 is a paddy receiving floor, 36 is a traveling clutch pulley, 37 is a self-release clutch pulley, 20a is an exhaust pipe of the muffler 20, 38 is a feed chain, and 39 is a pinching rail. They face the top plate 22d.

As mentioned above, in the present invention, a threshing device is mounted on the front part of a machine base having a traveling device, and at least a side plate and a rear wall are installed at the rear end of the machine base and on the supply port side of the threshing machine. A control panel with a control lever pivoted thereon is installed upright, an engine is mounted close to the front of the control panel, a control handle is attached to the rear of the control panel, and an engine cover containing the engine is mounted as above. Since the operation panel extends from the operation panel and becomes a part of the engine cover and also serves as a support member for the handle, the operation handle can be placed upright on the machine stand between the threshing device and the engine as in the past. The operation panel can be made more solid without having to create a complicated structure such as extending to the rear or extending to the front along the corners on both sides of the top of the engine cover, bending the front part downward and fixing it to the machine base. In addition to being lightweight, it can be provided at low cost.

In addition, since the various levers are pivoted on the side plate of the control panel, the control levers can be used not only at the rear of the control panel.
It can also be installed on the side of the supply port side of the threshing device, and can be used for running operations when moving the machine to the next working position after supplying grain culm to the threshing device, and for finishing the movement of the machine. The operation of moving on to threshing work, etc. can be easily and quickly performed.

Furthermore, the side plate of the operation panel and the side plate on the side of the supply port can be used as an engine cover, and can also be used as a support member for the engine cover, which reduces costs and allows the engine cover to be used as a support member. There is no need to add strength, and the engine cover can be made lightweight and inexpensive.
