Description

[Detailed description of the invention] This invention relates to a cover for a mobile agricultural machine used in a belt transmission system, a chain system, etc. Generally, for example, a cover is known that consists of two covers, one side cover and the other side cover, which can be separated and removed from each other. However,
Conventionally, one side cover and the other side cover were connected to each other via fasteners such as bolts and nuts.
Installation and removal were painless.

This invention was devised to improve the above-mentioned drawbacks, and aims to provide a cover that has a simple structure and is easy to install and remove.

Therefore, in this invention, the work equipment unit frame 5 is removably connected to a running section having a prime mover 25 and wheels 27 that are driven by the prime mover 25, and the driving rotary body 37 of the running section is provided. A power transmission mechanism 33 is provided that transmits power between the power transmission mechanism 33 and the driven rotary body 41 of the work equipment unit frame 5 through an endless body 45, and a cover 35a on one side attached to the running section side of the power transmission mechanism 33 and the work equipment unit frame 5 side are provided. A transmission cover 35 is provided, which consists of a second side cover 35b attached to the first side cover 35a and the other side cover 35b.
A transmission cover 35 which has a U-shaped cross section that can be overlapped with each other by opening the lower surface between the tip ends thereof, and one of which can be opened upward and is elastically fitted and connected with an elastic member 49 interposed therebetween. The structure of the power transmission cover for mobile agricultural machinery, etc. is made by covering.

Hereinafter, a preferred embodiment of this invention will be described in detail with reference to the drawings.

In Figures 1 and 2, numeral 1 indicates a one-wheel drive, single-row reaping and tying machine (hereinafter simply referred to as the machine body), numeral 3 indicates a weeding body for sorting grain culms, and a working machine. It is supported at the front of the unit frame 5 via a support rod 7. Reference numeral 9 denotes a lifting device for pulling up the grain culm, which is constructed by providing lifting lugs 15, 15, . . . at appropriate intervals on an endless belt 13 such as a rotating chain inside a lifting case 11. 17 is a reaping device for cutting the root part of the grain culm; 19 is a conveyance device for sending the grain culm cut by the reaping device 17 to the binding device 21; and 23 is the binding device 21 for binding the grain culm. This is a discharging device for discharging the grain culm bundles onto the ground.
25 is a prime mover, 27 is a drive wheel, and a transmission device 29
It is rotationally driven by the prime mover 25 via. These prime mover 25, driving wheels 27, and transmission device 29 constitute a running section, and the working machine unit frame 5 is attached to this running section. Reference numeral 31 denotes a handle extending diagonally rearward and upward from the traveling section, and 33 a power transmission mechanism for transmitting the power of the prime mover 25 to each rotating part, which is covered with a transmission cover 35 which is the gist of this invention.

The power transmission mechanism 33 is configured as follows. That is, 37 is a driving rotating body such as a pulley fixedly provided on the output shaft 39 of the prime mover 25, 41 is a driven rotating body such as a pulley etc. fixedly provided on the input shaft 43 of each rotating part, and 45 is the driving rotating body. An endless band such as a belt is passed between the rotating body 37 and the driven rotating body 41, and the power of the prime mover 25 is transferred from the driving rotating body 37 fixed to the output shaft 39 to the endless band 45 and the driven rotating body. 41 to an input shaft 43, and is configured to be distributed from this input shaft 43 to each rotating part.

As shown in FIGS. 3 and 4, the transmission cover 35 includes a transmission cover 35a on one side and a cover 35 on the other side.
Although it is made up of two parts (b), it is not necessarily limited to this, and it goes without saying that it may be made up of three or four parts. Said one side cover 35
A has a substantially U-shaped cross section, and one end (the left side in FIG. 3) is tapered into a stepped shape. The one-side cover 35a is fixedly or removably provided on the motor 25 side so as to cover part of the driving rotary body 37 and the endless band 45. On the other hand, the other side cover 35b has a U-shaped cross section like the one side cover 35a, and one end (the right end in FIG. 3) is connected to the one end of the one side cover 35a by fitting into each other. . An elastic member 49 is provided between the one-side cover 35a and the other-side cover 35b at a portion where the two are fitted together to prevent the two from becoming unfitted. This elastic member 49 is made of, for example, rubber, and is made of a material such as rubber.
5b, but in the embodiment, it is fixed to the inner surface of the end of the other side cover 35b.
The other end of the other side cover 35b is connected to one side wall (third
The front side wall (in the figure) is extended, and is screwed to the working machine unit frame 5 by a hinge 47 so that it can be opened and closed in the vertical direction.
It covers a part of the In addition, in the figure, 51 is
These are ground plates located on both sides of the front of the drive wheels 27 and attached to the working machine unit frame 5.

In the above configuration, when the motor 25 drives each rotating part to make the aircraft 1 travel, the aircraft 1
As the grain progresses, the grain culm entering the grass cutting body 3 is pulled up by the lifting lug 15 of the pulling device 9, and its base is cut off by the reaping device 17. The cut grain stems are sent to the binding device 21 by the conveyance device 19, bound by the binding device 21, and discharged to the ground by the discharge device 23.

Particularly, according to this invention, when the end of the other end cover 35b is fitted to the end of the one end cover 35b, the elastic member 49 is elasticized between the one end cover 35a and the other end cover 35b. Therefore, due to the frictional resistance, the covers 35a and 35b are prevented from coming apart, and the transmission cover 35 maintains its integrity.

The transmission cover 35 can be separated by simply rotating the other side cover 35b upward.

According to the configuration of this invention, a working equipment unit such as a reaping and tying machine can be connected to a traveling part consisting of a prime mover, drive wheels, etc., and one side cover can be placed on the traveling part side and the other side cover can be placed on the working equipment unit side. With the installed one,
When the work unit is removed from the traveling section, the transmission cover that covers the power transmission mechanism that transmits power between the traveling section and the work equipment unit frame moves the other side cover downward relative to the one side cover. Since the transmission cover can be connected by fitting or connected by opening upward, it is easy to connect, separate, and configure the transmission cover when attaching and detaching the work equipment unit frame to the traveling section, and the connected state of the transmission cover is simple. In this case, since the connecting ends are elastically fitted through the elastic member, frictional noise caused by body vibration etc. can be reduced, and a stable transmission cover can be constructed.
