Description

[Detailed Description of the Invention] The present invention relates to a car wash pump mounting device for a combine harvester, and its purpose is to install an engine mounted on the rear body of the combine that covers the engine. A mounting frame consisting of a vertical and horizontal frame that surrounds the rear side and bottom surface of the cover is fixed close to the engine room, and an engagement bracket is attached to the mounting frame, which can be freely attached to and detached from the mounting frame. The car wash pump is fixed on a pedestal equipped with a support shaft that engages with the support shaft, and the pump is engaged and held in the support via the support shaft, and is also interlocked and connected to the engine of the machine. It is extremely easy to install and remove, and due to the characteristics of the combine harvester, it prevents damage to the engine cover, which is easily damaged by hitting ridges due to poor visibility at the rear of the machine, such as when the machine is backed up during normal harvesting work. Moreover, the car wash pump can be attached and detached with one touch, and when washing the car, it is only necessary to start the engine without driving the threshing section or the reaping section, making it possible to wash the car safely. Moreover, it is an object of the present invention to provide a car wash pump mounting device for a combine harvester that has a simple structure and can be manufactured at low cost.

The structure of the present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1 is an engine located at the rear of the combine harvester body and disposed on the side of the threshing machine 2.
1' is an engine pulley, 3 is a transmission belt, and 4 is a running frame. 5 is a culm cutting device (cutter) connected to the rear of the threshing machine 2. Reference numeral 6 is a stay for attaching the engine cover 1a and the cutter 5, and is fixed to the rear end of the traveling frame 4.

7 is a car wash pump A fixed below the cutter 5 and near the rear of the engine room 1'a.
As shown in FIG. 2, this mounting frame 7 is constructed of a sturdy frame made up of vertical and horizontal frameworks of pipes 7a, 7b, and 7c, and mounting plates 7d and 7e are attached to both ends of the frame. Brackets 7f each having a substantially U-shaped side surface are fixed to the pipe 7b by welding or the like, and the mounting plate 7e side is fixed to the traveling frame 4, and the mounting plate 7d is fixed to the mounting plate 7e side.
The sides are connected and fixed to the stays 6, respectively. Reference numeral 7g denotes a metal fitting having a substantially L-shaped side surface fixed to the back side of the bracket 7f, and the engagement receptacle B is constituted by the metal fitting 7g and the bracket 7f.

7h is a flat plate fixed below the metal fitting 7g.
Reference numeral 8 denotes a trunk metal hook fixed to the lower surface of the bracket 7f via a bolt 8' and a nut 8''.

Reference numeral 9 denotes a pedestal on which a car wash pump A is placed and fixed, and is provided with rising parts 9a and 9b on both sides. A round bar-shaped support shaft 9c is attached which is detachably engaged and held. 9d is a stopper fixed below the support shaft 9c, and 9e is a trunk metal bolted to the lower surface of the base 9.

By the way, a driven pulley 10 is provided on one side of the car wash pump A, and a pump drive belt 12 is stretched between the driven pulley 10 and a pump drive pulley 11 fixed coaxially with the engine pulley 1'. ing. 13 is a water supply port, and 14 is a water discharge port. A hose 15 is connected to the water outlet 14 of the pump A, and injection nozzles 16, 16' can be detachably attached to the tip of the hose 15 via a screw-in type holder 15'. . 16 is a normal nozzle, 16' is a long nozzle for washing the lower part of the traveling frame 4, and a hook 16'a is integrally fixed to the tip. It is now possible to wash the car while scraping off chemical debris, mud, etc. 17 is a hose clamp, 18 is a rubber gasket, and 19 is a crawler traveling device. In the figure, 20, 21, 2
2 and 23 are bolts, and 24 and 25 are nuts.

In the configuration as described above, the car wash pump A and the pedestal 9 are removed from the mounting frame 7 during normal reaping work. When installing the car wash pump A on the combine harvester after finishing the harvesting work, use the round bar-shaped support shaft 9 attached to the pedestal 9.
c is fitted from above into the groove of the receiver B formed by the L-shaped metal fitting 7g and the bracket 7f to engage it. Then, with the pedestal 9 and the pump A fixed on the pedestal 9 tilted slightly forward as shown in FIG. After passing the pump A and the pedestal 9, the pump A and the pedestal 9 are rotated about the support shaft 9c in the direction of the arrow in FIG. Then tighten the hook to 8.

When the pump A is removed from the machine after the car wash operation is completed, the operation described above can be reversed.

In this invention, the mounting frame 7 and the pump A
Since the pump A is arranged in a space near the rear of the engine room 1'a below the cutter 5, the pump A can be easily installed and removed without removing the body covers such as the engine cover 1a each time. In addition, there is no risk of the mounting frame 7 interfering with the work during reaping work, so the mounting frame 7 can be attached to the machine at all times, and the pump A with the pedestal 9 can be carried alone. This is extremely convenient since all you have to do is carry it.

In addition, since the driving force for pump A is taken directly from the engine 1 on the machine side, there is no need to install a special power transmission mechanism such as a separate drive shaft, making the structure extremely simple. Since it is sufficient to simply start the engine 1 without operating the reaping section, there is no wastage of power and safe car washing work can be performed.

On the other hand, since the mounting frame 7 is attached to the aircraft so as to surround the rear side and bottom surface of the engine cover 1a, the mounting frame 7 has a strong frame structure and also serves as a protective frame (bumper) for the engine cover 1a. Therefore, the engine cover 1a can be prevented from being damaged even if it hits a ridge or the like when the aircraft is backed up.

As mentioned above, the present invention is a combine harvester with an engine mounted in the rear of the fuselage. A frame is fixed close to the engine room, an engagement receiver is attached to the mounting frame, a car wash pump is fixed on a pedestal provided with a support shaft that detachably engages with the receiver, and the pump is engaged and held in the receiver via the above-mentioned support shaft, and is interlocked and connected to the engine on the machine side, so the space at the rear of the machine can be effectively utilized and the car wash pump can be arranged compactly, and the car wash pump can also be installed. The pump can be removed very easily without removing the machine cover, etc., and the pump can be easily set on the machine only when doing car wash work. By removing the car wash pump from the machine body during reaping work, there is no risk of interfering with the work. In addition, since the mounting frame is fixed to the aircraft near the engine compartment so as to surround the rear side and bottom of the engine cover, reaping operations can be carried out with the mounting frame always attached to the aircraft. This eliminates the hassle of attaching and detaching the mounting frame to the aircraft each time, and the car wash pump can be attached and detached with a single touch only when washing the car.Moreover, the mounting frame serves as a protective frame for the engine cover, allowing the aircraft to This prevents the engine cover from being damaged even if the rear part of the machine hits a ridge with poor visibility, such as when backing up the machine.It also prevents the engine cover from being damaged during car washing without having to drive each working part such as the threshing part or the reaping part. Since it is only necessary to start the engine, no power is wasted, and car washing work can be carried out safely.Although the structure is simple and can be manufactured at low cost, it has extremely useful practical effects.
