Description

[Detailed Description of the Invention] Industrial Field of Application The present invention allows the paddy bags on the paddy holder of a combine harvester to be easily transported to a transport vehicle outside the machine, but it is also applicable to moving vehicles and equipment other than combine harvesters. Alternatively, the present invention relates to a rice bag carrying-out device in a combine harvester that can be easily attached to a structure and used for cargo handling operations other than rice bags.

Conventional technology and problems to be solved] In the past, in Nbain, a lift device for carrying out paddy bags was installed near the paddy receiving stand, and the full paddy bag was lifted up by the lift device and carried out to the road etc. Those that did this are already publicly known (for example, Japanese Utility Model Application Publication No. 17850, Japanese Utility Model Application Publication No. 8)
0-164847, etc.). However, all of these lift devices are pre-integrated into the combine for the purpose of transporting paddy bags, and the hydraulic cylinders that drive the lift devices are also linked to the hydraulic mechanism mounted on the combine main body. Therefore, not only was the structure complicated, but it could not be used for any purpose other than transporting rice bags.

Means for Solving the Problems Therefore, the present invention forms a crane body for carrying out paddy bags that is integrally equipped with crane-related parts such as a telescoping drive unit and an operating unit, and also provides support legs of the crane body to a combine harvester. The above-mentioned problems are solved by providing a support leg and attaching the crane main body to the support leg in a detachable manner.

Operation When the paddy bag on the paddy receiving stand is full and the paddy bag is to be carried out of the machine, use the crane body attached to the combine harvester to directly lift the full paddy bag from the paddy holding stand. It can be easily carried out and transferred to a transport vehicle, etc.

In addition, if you attach it to the support legs of the crane body to a moving vehicle (truck, etc.), equipment, or structure (dryer, etc.) other than the combine harvester, you can remove only the crane body from the combine and attach it to these support legs. By changing the crane body, the crane body can be easily used for cargo handling operations other than carrying out paddy bags.

Example A is a combine harvester, and between the driving wheel 1 and the driven wheel 2 there are rollers 3a to 3a.
3d and a crawler traveling device 5 formed by winding an endless belt 4
A pre-processing section 7 is mounted on the front side of the fuselage frame 6 supported by the engine 8 so as to be movable up and down via a hydraulic cylinder (not shown). The driver's seat 9 is located behind the driver's seat 9, and the threshing section 1 is located on the other side behind the driver's seat 9.
A paddy holder 11 is installed on the side of the threshing section 10 and behind the driver's seat 6, and a cutter 12 and other culm processing devices are installed at the rear of the machine adjacent to the threshing section 10. is equipped with. The grains that have been threshed in the threshing section 10 and have been sorted in the sorting section are transferred to the first spiral (not shown) in the threshing section 1.
After being transferred to one side of 0 (the side of the paddy holder 11),
The paddy is lifted up and sequentially discharged from the gutter 14 into a paddy bag a suspended above the paddy receiver 11 via a hanger 15. By the way, the grain lifting cylinder 13 is robustly constituted by a thick cylinder in which a spiral body (not shown) is rotatably installed, and extends along the inner side plate 10a of the threshing section 10 approximately midway in the longitudinal width direction of the paddy holder 11. The base end side is firmly fixed on the body frame 6. 16 is a paddy receiver cover. Reference numeral B designates a crane body for transporting rice bags, which has a boom b with a two-stage folding structure in which the middle part can freely rotate in the vertical direction, and the crane body B has a fitting shaft part 17b (third A first boom 18 is supported on a post (see figure) 17 via a spindle 19a so as to be vertically movable, and a second boom 20 is connected to the first boom 18 via a spindle 20a so as to be vertically movable. The tip of the second boom 20 is bent downward and a hook 21 is provided at the bent end, and each boom 19
．． 20 has a two-step folding structure whose elevation angle can be adjusted by hydraulic cylinders 22 and 23, respectively. The crane body B is integrally equipped with crane-related parts such as a telescopic drive section and an operating section M. That is, an oil tank 24 in a separate system independent from the combine harvester side, an electric motor 25 with a hydraulic pump, etc., and a telescopic drive section are placed on the rear side of the upper part of the post 17, and a lifting lever 26 is placed on the side of the first boom 19. , an operating section M consisting of a switching valve 28 and the like having lifting levers 27 juxtaposed in an upwardly protruding manner on its outer side;
Brackets located on the left side of the boom 19 near the base (with respect to the aircraft traveling direction, the same applies hereinafter) and attached to the bottom of the post 17)
It is fixed via 29.30, and only the power source is powered by the 8-terry on the combine harvester side.

Incidentally, the battery may also be installed on the crane main body B side. The crane main body B configured as described above is attached to the pipe-shaped support leg 31 provided on the combine harvester A so as to be horizontally rotatable and detachable. The support leg part 31 is located between the driver's seat 9 and the paddy holder 11 via a bracket 32 fixed to the upper part of the grain lifting cylinder 3, and is integrated with the grain lifting cylinder 13 in close proximity to the front of the grain lifting cylinder 13. It is connected and fixed. Therefore,
From the position in relation to the grain lifting cylinder 13, the support leg part 31 is located between the threshing part 10, which is the middle part of the left and right crawlers 4, 4, and the paddy holder 11, and between the idler wheel 2 of the crawler 4 and the first rolling wheel 3d. The crane has an ideal leg configuration for the balance of the machine as a crane for transporting rice bags. By the way, the bracket 32 is also connected and fixed to the machine frame 6 via an L-shaped stay 33 that passes through one side of the rice holder 11 (driver's seat 9 side), further increasing the mounting strength of the support leg 31. . Note that both the grain lifting tube 13 and the fuselage frame 6 have high rigidity, so the support leg portion 31 may be fixed to either the grain lifting tube 13 or the fuselage frame 6.
Sufficient mounting strength is ensured. Now, a flange 34 having an arc-shaped elongated hole 34a centered on the axis of the support leg 31 is integrally fixed near the upper edge of the support leg 31, and the lower end of the boss 17 is fitted into the flange 34. Shaft part 1? b to support leg 31
The flanges 17a and 34 are fixed to each other with a lockport 35. Further, when the crane main body B is set on the support leg portion 31, the post 17 projects upwardly from the top of the grain lifting cylinder 13. A lock pin system may be adopted instead of the lock port 35, and in this case, a plurality of positioning pin holes may be provided in the flange 34 on the support leg portion 31 side. In the illustrated example, the flange 34 and the elongated hole 34a are provided in a specific range rather than the entire circumference of the support leg 31, so that when the lockport 35 comes into contact with the edge of the elongated hole 34a, the boom b moves into the appropriate paddy bag. The flange 34
By providing the elongated hole 34a over the entire circumference of the support leg 31, the crane main body B can be completely rotated around the support leg 31. 12th grade culm processing equipment,
This will save labor when attaching, detaching, and repairing various parts of the machine, such as the threshing section. In the above embodiment, a gutter-type combine harvester was described in which the grains after the sorting process are directly discharged into the paddy bag a on the paddy tray 11 through the grain lifting cylinder 13, but the present invention It can also be adopted in a hopper-type combine harvester in which the rice is temporarily stored in a hopper mounted on the machine and the paddy bag a is replaced when the hopper is full.

In the above configuration, Rockport 35 is used during reaping work.
Loosen the crane B and move it towards the inside of the aircraft.
Push and rotate the levers by hand until they touch the edge of the elongated hole 34a, and at the same time push and rotate the levers 2B, 2? If the first and second booms 19 and 20 are extended to a substantially horizontal state by the operation, the tip of the boom b will be in a proper reaping working posture in alignment with the upper part of the left end grass division d1 of the pretreatment section 7, and the crane body B will be moved to the lock port 35. Fix it in this position. As a result, the boom b passes to the left side of the driver's seat 9 and is locked while being compactly stored within the fuselage mountain, so the boom b does not get in the way of the operator or obstruct the forward view from the driver's seat 9. Instead, the tip of the boom can serve as a marker indicating the position of the left end weeding body d1, which is difficult to see from the driver's seat 9.

In addition, since the boom b is held in an inclined state from behind the driver's seat 9 provided on the negative side of the machine body to the other side of the machine body above the preprocessing section 7 in plan view, the left-right balance of the machine body is maintained well. Even if the rear balance is affected by a heavy object such as a knotter attached to the rear, the weight of the boom 5 will correct the front-rear balance of the aircraft. Incidentally, it is also possible to lock a weight to the tip of the poom b if necessary.

At the start of the reaping work, the grains after threshing and sorting are sequentially discharged from the gutter 14 into the paddy bag a on the paddy receiver 11 via the grain lifting cylinder 13, and when the paddy bag a is full, the machine is moved to the roadside. Then, the work moves on to carrying out the paddy bag a. At this time, the lifting lever 26 is operated from the driver's seat 9 position so that the boom b does not hit the operator's head, and the seam b is brought into the forward upward position in advance. Then, after loosening the lock port 35 and rotating the boom b by hand to the paddy holder 11 as shown in the phantom line in FIG. 2, operate the lifting lever 27 to move the second boom 20 as shown in FIG. 6. Bend the hook 21 downward until it touches the upper outer surface of the paddy bag a, remove the paddy bag a from the hanger 15, hook the hanging string a' on the hook 21, and operate the lever 28.27. The paddy bag a is lifted from the paddy holder 11 and transferred to a transport vehicle C or the like on the road. By the way, the support leg part 31 of the crane main body B is provided between the driver's seat 9 and the paddy cradle 11, and the telescopic drive part and the operating part M of the crane are arranged around the rotation fulcrum of the crane near the driver's seat 9. Since it is integrated with the crane main body B, the operator can easily operate it while remaining in the driver's seat 9. In addition, the crane body B is provided with a hydraulic system powered by a battery, separate from the hydraulic power source of the combine, so that the crane can be operated even when the Alnote engine is stopped (during maintenance of the combine, etc.). The center of gravity of the paddy pedestal 11 changes depending on the amount of paddy, but the threshing section 10 is stable with little change in the amount of paddy.

The boom fulcrum part (support leg part 31) is the stable threshing part 1
Along the inner side plate 10a of 0 and on the left and right crawlers 4.4
Since it is located near the middle of the paddy bags, there is little change in balance when lifting paddy bags, allowing for stable cargo handling operations. In addition, the boom fulcrum is located at a position where the center of gravity does not shift even when there are fluctuations in each working machine (such as raising the pre-processing section or loading and unloading paddy), that is, closer to the first roller 3d between the idler wheel 2 and the first roller 3d of the crawler. Since the combine harvester A is provided in the same position, even when the boom b is rotated back and forth, the combine A does not tilt up or hip up, allowing stable and safe work to be performed.

On the other hand, when storing the machine or loading and unloading the combine onto a truck, etc., by keeping the second boom 20 in the downward bent position shown in the phantom line in Figure 1 from the reaping work position, the amount of forward protrusion of the boom b is reduced, making it safer. Moreover, the cover is easy to put on and space can be saved. The crane body B may be removed from the combine A and transported and stored separately.

By the way, the crane main body B according to the present invention includes an oil tank 24, an electric motor 25 with a hydraulic pump, etc., and a telescoping drive unit, a switching valve 28, a control lever 26 for lifting and lowering, a lever 27 for lifting, etc. Crane-related parts such as part M are integrated, so the power supply (
It can be operated anywhere as long as there is a battery), and therefore it can be operated anywhere with a battery (battery), and therefore it can be operated on moving vehicles other than combines such as trucks, equipment, and other structures (
For example, the support legs 31 are attached in advance to a dryer), etc.,
During the off-season, by removing the crane body B from the combine harvester A and replacing it with these support legs, various cargo handling operations other than carrying out paddy bags can be easily performed, resulting in further labor savings and higher efficiency. This allows the crane body B to be used effectively throughout the year.

Effects of the Invention As described above, the present invention forms a crane body for carrying out paddy bags that is integrally equipped with crane-related parts such as a telescoping drive unit and an operating unit, and also attaches support legs of the crane body to a combine harvester. Since the crane main body is detachably attached to the support legs, it is possible to use the crane to carry out paddy bags even when the engine of the combine is stopped, and it is also possible to use a mobile vehicle other than the combine (such as a truck),
By attaching support legs for the crane body to equipment or structures (such as dryers), it is possible to remove only the crane body from the combine and replace it with these support legs for cargo handling other than carrying out paddy bags. It is possible to perform the work easily, and it is possible to save labor and increase the efficiency of various cargo handling operations.
