Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a storage device for a hose for a car wash pump of a self-removal combine harvester or a harvester, in which a rocking plate for grain sorting is provided obliquely at the rear of the threshing section.

<Conventional technology> When a pump for car washing is attached to the body of a working machine as described above, conventionally, the pump is attached when washing the car after work, and at that time, the hose for water supply and drainage is also attached at the same time. A mechanism is known in which these are removed and stored in a separate location from the vehicle body after the car wash is completed.

<Problems that the invention aims to solve> However, as mentioned above, if the pump and hoses are separate from the machine body, there is a hassle of attaching and detaching the hoses each time you wash the car, and it is also difficult to store the hoses etc. when washing the car. There is the inconvenience of having to go to pick it up or move the aircraft to a location with hoses, etc.
Furthermore, there were other problems such as it being especially inconvenient when it was necessary to wash the car immediately after working in a wet field, or when trying to wash the car at any time in a place where the access to water and location conditions were suitable for car washing. .

<Means for Solving the Problems> In order to solve the above problems, the present invention provides a threshing system that allows the suction hose and discharge hose for a car wash pump to be freely taken out or stored at any time and place. In a mechanism in which a rocking plate 31 for grain sorting is provided obliquely at the rear lower part of the body, and a space 35 opened to the rear is formed between the rocking plate 31 and the rear end of the fuselage frame 3, the space Inside the section 31, drums 67 and 69, on which the suction hose 49b and the discharge hose 51b connected to the car wash pump 37 can be individually wound or unwound, are arranged in the left and right direction and rotatably supported, A relay shaft 81 that rotates in conjunction with one of the drums 67 is installed horizontally in the section 35, and a handle for rotating the drum shaft 65b of the other drum 69 and the relay shaft 81 is provided on one side of the outside of the space 35. 79 and 93 are provided.

<Operation> When washing the machine body 1, the suction hose 49b and the discharge hose 51b are pulled out and the drums 67 and 69 are rotated to let out the required amount of hose ends, and the strainer 71 portion on the suction hose 49b side is inserted into water in a water tank or other water. However, when the car wash pump 37 is activated, it is connected to the car wash pump 37 in advance, or
Water sucked through the suction hose 49b connected during work is discharged to the nozzle 73 through the suction hose 49a, the car wash pump 37, and the discharge hoses 51a and 51b, making it possible to wash the car.

After the work, water is drained from the pump and hoses as necessary, and the drums 67 and 69 are rotated in the opposite direction, so that the suction hose 49b and the discharge hose 51b are wound up and stored.

<Example> To explain in detail the embodiment of the present invention shown below, FIG. The vehicle touches the ground at a running section 5, and a pre-processing section 7 is attached in front of the running section 5.

The pre-processing section 7 has a scraping device 1 on the pre-processing frame 9.
A clipper-like cutting blade 15 is attached to the bottom of each case, and a transmission shaft case 17 is installed at the rear of the lower part of the pretreatment frame 9.
It is connected to the lower end of the rotary member via a rotary portion 19 so as to be rotatable from side to side (rolling). Threshing section 2 on the machine body 1 side
A conveying device 2 is interposed between the feed chain 23 of No. 1 and the raking device 11 for relaying and lifting up the grain rods after harvesting, and the front end of the conveying device 25 is connected to the rear of the raking device 11. By swinging up and down, the grain rod relay section 27 adjusts the handling depth.

A straw processing section 29 for tying or cutting waste straw is provided behind the threshing section 21.
At the rear lower part of the interior, there is a rocking plate 31 which temporarily places grains and scraps that have fallen from the handling chamber and which sorts the grains by specific gravity by rocking the rocking plate 31, which rises toward the rear. On the back side of the swing plate 31, a bottom cover 33 of the sorting section is installed obliquely along the slope of the swing plate 31, and the back side of the bottom cover 33 and the back of the fuselage frame 3 are arranged obliquely. A space 35 is formed between the upper surface of the end portion and the space portion 35 that is opened at an acute angle toward the rear by the respective surfaces.

A car wash pump 37 is attached to the rear right side (driver's seat side) of the fuselage frame 3 as shown in FIG. It is wound around and operated by a lever 47. 49
a, 51a are suction hoses and discharge hoses, one end of which is attached to the car wash pump 37, and each hose 49a,
The other ends 51a extend to the left (towards the threshing section) along the rear end of the body frame 3, as shown in FIG. 1, and are connected to a storage device 53, which will be described below.

The storage device 53 has brackets 55, 56, 58 on the body frame 3 of the space 35 and shafts 63a, 63b, 65 on the side plate 59 of the sorting section.
The drums 67, 69 each have two drums 67, 69 rotatably supported laterally by a, 65b.
The shafts 63a and 65a on the right side of 69 are hollow shafts,
The ends of the suction or discharge hoses 49a, 51a are connected to their respective externally protruding ends.

Further, each drum 67, 69 has suction or discharge hoses 49b, 51b rotatably connected within the drum via the suction or discharge hoses 49a, 51a and shafts 63a, 65a for winding and winding. are freely wrapped around each hose 49b, 51.
A strainer 71 and a discharge nozzle 73 are attached to the tip of b. Reference numerals 75 and 77 are hose guides for winding and unwinding the hose while rotating the respective drums 67 and 69.

The end of the drum shaft 65b on the side where the discharge hose is wound is
A handle 79 for rotating the drum protrudes from the outer surface of the side plate 59, and a handle 79 for rotating the drum is attached to the protruding end. The relay shaft 81 forms a mechanism that rotates integrally with the sprockets 83, 83 attached to each and the chain 85 wound therebetween, and further includes a side plate 59.
The handle shaft 87, which is pivotally supported, and the sprockets 89, 89 attached to the left end of the relay shaft 81 are also wound around the chain 91, so that both shafts 81, 87 rotate together. Reference numeral 93 denotes a handle attached to the handle shaft 87. By operating this handle 93, the drum 67 on the suction hose side is rotated via the relay shaft 81.

FIG. 4 shows a front view of the combine harvester, and in this example, guide plates 14, 14 are provided on the upper opposing surfaces of the left and right lifting cases 13, 13 and project inward in turn, so that the upper ends of the cases are closed. The inner side of the guide plate 14 on the back side has an apron shape bent at a substantially right angle to the back side, as shown in FIG. Each guide portion 14a is formed. This mechanism prevents the inconvenience of grain rods (especially grain rods with poor rigidity, weeds, etc.) being lifted up to the upper end of the case by the lifting claw 16 and being brought into the cases 13, 13. At the same time, each guide plate 1
The tips of the grain rods are gathered in the center between 4 and 14, and transferred to the rear conveying device 2 without being disturbed.
5. It has an excellent effect of being transferred smoothly.

In addition, in the example shown in FIGS. 4 and 5, as described above, the preprocessing section 7 has a mechanism in which the rotating section 19 rotates left and right with respect to the machine body 1. As shown in the figure, even if the machine body 1 during work is tilted by an angle of inclination θ due to softness of other boards, etc., the pre-processing section 7 can be kept horizontal as shown in the drawing 20, and as a result, fluctuations in the cutting height can be prevented. In other words, it is possible to prevent threshing defects caused by uneven lengths of grain rods.

In the particularly shown mechanism, the rotating part 19 of the pre-processing part 7
The center of the grain rod is transferred from the raking device 11 to the conveying device 25.
By aligning the center of the relay section 27 inherited as much as possible and providing it at a position below it, the scraping device 1 is moved as the pre-processing section 7 rotates from side to side.
The amount of variation in the distance l (see FIG. 2) between the star wheel 12 of No. 1 and the stock transfer section 26 of the transfer device 25 can be minimized. As a result, there is almost no displacement of grain rods between the star wheel 12 and the grain transfer section 26, and the handling depth is adjusted by making the transfer device 25 follow each time the pretreatment section 7 rotates left and right. This has the advantage that there is no need to do so.

<Effects of the invention> According to the hose storage device of the present invention constructed as described above, the inconvenience of having to bring the hose to a predetermined position on the machine each time, moving the machine, and attaching and detaching the hose each time is eliminated. This provides advantages such as being able to wash the car arbitrarily and easily whenever and wherever possible, and also making it extremely easy to take out and store the hose.

In addition, the storage device is installed in the rear of the aircraft's rocking plate, making use of an unused space to be stored there, so the space around the aircraft can be used effectively, and the equipment can be placed closer to the aircraft than the rest of the aircraft. This has the advantage that it does not protrude significantly and does not interfere with the attachment or operation of other mechanical parts.

Furthermore, since the suction hose drum and the discharge hose drum are each operated by handles installed side by side on the side of the space, they can be freely extended to any length depending on the distance of the car washing position or water suction position of the aircraft. It also has the advantage of being easy to operate from a single location on the aircraft.
