[0001] The present invention relates to a harvesting machine that performs harvesting work in a farm field. [Background technology]

[0002] The harvesting machine is provided with a side carrier on the outer side of the machine body of a recovery section that recovers grains from a hopper into rice bags, on which an operator rides to perform recovery work (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-130951 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the side carriers were only located on the outer side of the fuselage in the retrieval section, and work required moving to the front or rear of the side carrier, which required repeated boarding and disembarking from the side carrier, making the work less efficient.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a harvesting machine with good operability. [Means for solving the problem]

[0006] The invention described in claim 1 is a harvesting machine having a body having running gear 3, 3 and a control unit 7, a harvesting device 5, a threshing device 6, and a hopper 30, and a side carrier 32 on the outside of the hopper 30, in which a front extension carrier 33 extending to the outside of the control unit 7 is provided in front of the side carrier 32 so as to be freely switched between an open working state to the outside of the body and a folded-up storage state inside the body.

[0007] According to the invention described in claim 1, the side carrier 32 and the front extension carrier 33 provide a wider foothold during grain recovery work, making recovery work easier and improving workability.

[0008] In addition, since the front extension carrier 33 is located in a position that allows the operator to move to the control section 7, the operator can freely move between the side carrier 32 and the control section 7, improving the efficiency of the harvesting work.

[0009] In addition, a collection container filled with grains can be temporarily placed on the front extension carrier 33 located in front of the side carrier 32, making it easy to collect the collection container and take it out of the field.

[0010] The invention described in claim 2 is the harvesting machine described in claim 1, in which a rear extension carrier 34 is provided behind the side carrier 32, protruding rearward beyond the rear end of the fuel tank 35 provided at the rear of the machine body, and a balance weight 36 is provided on the rear extension carrier 34 in a freely attachable and detachable manner.

[0011] According to the invention described in claim 2, the working space for recovering the rear extension carrier 34 can be expanded, and the fuel tank 35 can be protected.

[0012] In addition, the center of gravity of the aircraft can be stabilized by attaching and detaching the balance weight 36.

[0013] The invention described in claim 3 is a harvesting machine described in claim 1 or claim 2, in which a recovery carrier 31 for carrying a recovery container arranged below the hopper 30 is freely movable in the left and right direction toward the outside of the machine body, and the recovery carrier 31 is of an integrally molded configuration with wall portions 31b, 31c corresponding to the rear side of the control unit 7 and the engine E and the inside of the threshing device 6.

[0014] According to the invention described in claim 3, the collection carrier 31 can be slid from the collection position below the hopper 30 to the side carrier 32 on the outside of the aircraft body, and the collection container placed on the collection carrier 31 can be easily lowered to the outside of the aircraft body.

[0015] In addition, since the recovery carrier 31 is an integrally molded structure having wall portions 31b, 31c corresponding to the rear side of the control unit 7 and the engine E and the inside of the threshing device 6, the recovery carrier 31 can also serve as a partition between the control unit 7 and the engine E and the threshing device 6, resulting in low manufacturing costs.

[0016] The invention described in claim 4 is the harvesting machine described in claim 3, in which the inside of the recovery carrier 31 is filled with a load dispersion material such as urethane or air.

[0017] According to the fourth aspect of the invention, the load of the collection container applied to the collection carrier 31 can be dispersed, improving durability.

[0018] The invention described in claim 5 is a harvesting machine as described in claim 1, in which the engine cover 13 provided on the outside of the control unit 7 has mounting platform plates 37U, 37D that can be freely switched between an working state where they are open to the outside of the body and a stored state where they are folded inside the body, and when the mounting platform plates 37U, 37D are in the stored state, they overlap the engine cover 13, and air intake holes are formed in the mounting platform plates 37U, 37D.

[0019] According to the invention as recited in claim 5, collection containers and the like can be placed on the placement plates 37U, 37D in the working state near the side carrier 32, improving work efficiency.

[0020] Furthermore, when the mounting base plates 37U, 37D are stored, they overlap with the engine cover 13, and since the mounting base plates 37U, 37D have the intake holes formed therein, they do not impede the intake of air into the engine E (radiator). [Brief description of the drawings]

[0022] Hereinafter, a combine harvester as one embodiment of a harvesting machine of the present invention will be described in detail with reference to the drawings.

[0023] For ease of understanding, the following description will refer to the front as the front side, the rear as the rear side, the right hand side as the right side, and the left hand side as the left side, as viewed from the pilot's perspective; however, the present invention is not limited to these terms.

[0024] FIG. 1 shows a side view of a combine harvester for harvesting grain according to an embodiment of the present invention, FIGS. 2 and 4 show plan views of the main parts of the combine, and FIG. 3 shows a side view of the main parts of the combine.

[0025] The lower part of the combine harvester's body frame 1 is provided with left and right traveling devices 3, 3 equipped with crawlers 2 formed into an endless belt shape made of a flexible material such as rubber.

[0026] A reaping device 5 is supported at the front of the machine frame 1 so as to be freely rotatable up and down, and a threshing device 6 is mounted on the rear left side of the machine frame 1 behind the reaping device 5.

[0027] A control section 7 having an operator's seat 7a is provided on the right front portion of the aircraft frame 1.

[0028] The control unit 7 consists of an operator's seat 7a attached on an engine cover 13 that covers the engine, a front operation panel located in front of the operator's seat 7a, and a side operation panel located to the left of the operator's seat 7a.

[0029] On the front operation panel are provided a handle 7b which the pilot holds when operating the drone in a standing position, and a steering lever 7c which switches the transmission mechanism in the transmission case to adjust the vehicle's running direction to the left or right.

[0030] On the side operation panel are provided a throttle lever 7d for adjusting the rotation speed of the engine E, a main speed change lever 7e for changing the speed of the hydrostatic continuously variable transmission that inputs drive to the transmission case, a sub-speed change lever 7f for changing the speed of the sub-speed change mechanism in the transmission case, a harvesting clutch lever for switching the drive of the harvesting device 5 on and off, and a threshing clutch lever for switching the drive of the threshing device 6 on and off.

[0031] The reaping device 5 is supported by a longitudinal support frame 9 whose base is rotatably attached to the machine frame 1, and is configured to be movable up and down by a reaping cylinder.

[0032] The harvesting device 5 has a plurality of grass bodies 10 at the frontmost position, and behind each grass body 10 is a lifting device 11 equipped with a lifting lug for lifting the divided culms.

[0033] Adjacent to the right of the threshing device 6 is a hopper 30 which stores the grains transported from the threshing device 6 and discharges them downward, and in front of the hopper 30 is an operating unit 7 having an operating seat 7a.

[0034] The precleaner 15 is attached to a precleaner support member 15a whose base is fixed to the front of the hopper 30. The hopper 30 also serves as the support frame for the precleaner 15, contributing to weight reduction and cost reduction by reducing the number of parts, and improving the ability to traverse wet fields.

[0035] In addition, the air cleaner 16 is also provided on the machine frame behind the operator's seat 7a on the front side of the hopper 30, and the precleaner 15 and air cleaner 16 are positioned away from the engine E, allowing air to be taken in at a position that is not affected by the exhaust heat of the engine E.

[0036] The hopper 30 is provided with two funnel sections 30a, 30a at the front and rear, and the rice is placed into a rice bag serving as a collection container from the lower parts of the two funnel sections 30a, 30a.

[0037] Below the funnel portions 30a, 30a of the hopper 30, a recovery carrier 31 is provided on which the rice bags are placed.

[0038] The recovery carrier 31 is made of resin and has a hollow portion which is filled with urethane, air, etc., and is integrally formed with a bottom surface 31a on which the rice bag is placed, a front wall 31b which serves as the wall on the engine E side, and an inner wall 31c which serves as the wall on the threshing device 6 side.

[0039] Therefore, since the recovery carrier 31 is a one-piece molded resin product, the manufacturing cost is low, and together with the reduced number of parts, it is lightweight, which contributes to improving the running performance of the combine, and is easy to handle.

[0040] In addition, since the recovery carrier 31 has a front wall 31b on the engine E side and an inner wall 31c on the threshing device 6 side integrally formed, it can be used as a partition between the engine E and the threshing device 6, and manufacturing costs are low.

[0041] In addition, the recovery carrier 31 is made of resin with a hollow portion which is filled with urethane, air, etc., so that the grains in the hopper 30 are filled into the rice bag through the funnel portion 30a, and the load of the rice bag can be distributed and supported, improving durability.

[0042] Furthermore, if the surface of the recovery carrier 31 is coated with fluororesin, it becomes more slippery, and the rice bags can be easily slid over the bottom surface 31a of the recovery carrier 31 and lowered to the side of the machine body, improving workability.

[0043] Conversely, the surface of the collection carrier 31 may be made uneven in a mesh-like pattern (for example, by attaching a mesh-like member to form an uneven surface) to make it non-slip, thereby preventing the rice bags from moving rapidly on the collection carrier 31 and preventing them from coming into contact with workers or the grains inside the rice bags from spilling out.

[0044] In addition, the recovery carrier 31 can be freely moved left and right between a discharged rice grain receiving position located below the funnel portions 30a, 30a of the hopper 30 and a rice grain bag unloading position where it is slid to a side carrier 32 (described below) on the side of the machine body.

[0045] Therefore, when the recovery carrier 31 is placed in the discharge rice husk receiving position located below the funnel portions 30a, 30a of the hopper 30, the grains in the hopper 30 are discharged through the funnel portion 30a and filled into the rice husk bag placed on the recovery carrier 31.

[0046] When the rice sack is filled with grains, the recovery carrier 31 is slid onto the side carrier 32 on the side of the machine body, and the rice sack placed on the recovery carrier 31 can be easily lowered to the outside of the machine body.

[0047] The side carrier 32 is located on the outer side of the body of the recovery carrier 31 when it is in the discharge rice husk receiving position located below the funnel sections 30a, 30a of the hopper 30, and has a front-to-rear pivot axis on the inner end of the body, so that it can be freely switched and fixed between a working state opened to the outer side of the body (see Figures 1 and 2) and a storage state folded inside the body (see Figures 3 and 4).

[0048] During harvesting, the side carriers 32 are opened outward from the machine body to a working state, and a worker gets on the side carriers 32, places a rice bag on the recovery carrier 31 set to a discharged rice receiving position, and fills the rice bag with grains discharged from the funnel parts 30a, 30a of the hopper 30.

[0049] When the rice sack is filled with grains, the worker gets off the side carrier 32, slides the recovery carrier 31 onto the side carrier 32 on the side of the machine body, and lowers the rice sack placed on the recovery carrier 31 to the outside of the machine body.

[0050] A front extension carrier 33 is provided at the front of the side carrier 32.

[0051] The front extension carrier 33 can be freely switched and fixed between an open working state (see Figures 1 and 2) toward the outside of the aircraft and a folded-up storage state (see Figures 3 and 4) toward the inside of the aircraft, by a fore-and-aft pivot axis provided on the inside end of the aircraft frame 1 below the engine cover 13.

[0052] When the front extension carrier 33 is opened outwardly of the machine body during harvesting operation, the upper surface of the side carrier 32 and the upper surface of the front extension carrier 33 become flush with each other, providing a wider foothold for grain discharge operation, making the operation easier and improving workability. Furthermore, since the front extension carrier 33 is located in a position that enables the operator to move up to the control unit 7, the operator can move freely between the side carrier 32 and the control unit 7, improving the efficiency of harvesting operation.

[0053] In addition, rice bags filled with grains can be temporarily placed on the front extension carrier 33 located in front of the side carrier 32, making it easy to collect the rice bags and take them out of the field.

[0054] A rear extension carrier 34 is provided at the rear of the side carrier 32.

[0055] The rear extension carrier 34 can be freely switched and fixed between an open working state toward the outside of the aircraft body (see Figures 1 and 2) and a folded-up storage state toward the inside of the aircraft body (see Figures 3 and 4) by a left-right pivot axis provided on the inside end of the aircraft body at the rear end of the aircraft frame 1.

[0056] The rear extension carrier 34 is provided rearward of a fuel tank 35 provided at the rear of the aircraft frame 1, and functions as a protective member for the fuel tank 35.

[0057] When the rear extension carrier 34 is opened toward the rear side of the machine body during harvesting work, the upper surface of the side carrier 32 and the upper surface of the rear extension carrier 34 become flush with each other, providing a wider foothold for grain discharge work, making work easier and improving workability, and also allowing work on the rear part of the machine body to be performed, improving the efficiency of harvesting work.

[0058] In addition, rice bags filled with grains can be temporarily placed on the rear extension carrier 34 located behind the side carrier 32, making it easy to collect the rice bags and take them out of the field.

[0059] In addition, a balance weight 36 is detachably provided on the bottom surface of the rear extension carrier 34, so that the front-rear balance of the machine body can be adjusted and the center of gravity of the machine can be stabilized, improving the running performance and enabling proper harvesting work.

[0060] 5 to 8 show an embodiment in which, instead of the front extension carrier 33, an upper mounting base plate 37U and a lower mounting base plate 37D are provided on the engine cover 13 in two stages, one above the other.

[0061] That is, the upper and lower mounting base plates 37U and 37D are made of a mesh material such as a mesh iron plate or expanded metal, and can be freely switched and fixed between an open working state toward the outside of the aircraft (see Figures 5 and 6) and a folded-up storage state toward the inside of the aircraft (see Figures 7 and 8) by means of a longitudinal pivot shaft provided on the inner end side of the aircraft at the upper and lower central positions and the lower position of the engine cover 13.

[0062] During harvesting operation, when the upper loading platform plate 37U and the lower loading platform plate 37D are opened outward toward the outside of the machine body, the upper surface of the side carrier 32 and the upper surface of the lower loading platform plate 37D become flush with each other, providing a wider platform for discharging grain, making the work easier and improving workability. In addition, by placing rice sacks filled with grains on the upper loading platform plate 37U and the lower loading platform plate 37D, the rice sacks can be easily collected and taken out of the field.

[0063] In addition, when the upper mounting base plate 37U and the lower mounting base plate 37D are folded and stored inside the aircraft, the upper mounting base plate 37U and the lower mounting base plate 37D are made of a mesh material such as a mesh iron plate or expanded metal (with air intake holes formed) and overlap the engine cover 13, so that ventilation is possible and they do not obstruct the intake of air to the engine E (radiator).

[0064] 9 and 10 show an embodiment in which the recovery carrier 31 is moved onto the side carrier 32 by a double-acting hydraulic cylinder 38, instead of the configuration in which the recovery carrier 31 is manually slid onto the side carrier 32 on the side of the aircraft body.

[0065] That is, the tip of the piston 38a of the double-acting hydraulic cylinder 38 fixed to the body frame 1 is connected to the inner wall 31c of the recovery carrier 31, the recovery carrier 31 is placed on a slide rail 39' so that it can move freely left and right, and an operating lever or switch for operating the double-acting hydraulic cylinder 38 is provided at the control unit 7 at the front of the body and / or at the rear of the hopper 30 at the rear of the body.

[0066] Therefore, when the rice bag placed on the recovery carrier 31 is filled with grains after receiving the grains discharged from the funnel section 30a of the hopper 30, an operator at the control section 7 or an operator at the rear of the machine body (on the side carrier 32) operates an operating lever or switch to extend the piston 38a of the double-acting hydraulic cylinder 38, and the recovery carrier 31 slides onto the side carrier 32 on the side of the machine body. Thus, the operator can easily and efficiently lower the rice bag placed on the recovery carrier 31 to the outside of the machine body.

[0067] Then, the operator in the control section 7 or the operator at the rear of the machine (on the side carrier 32) operates the operating lever or switch to retract the piston 38a of the double-acting hydraulic cylinder 38, sliding the emptied recovery carrier 31 below the funnel section 30a of the hopper 30 inside the machine, and placing the empty rice bag on the recovery carrier 31 to resume the grain recovery operation in the hopper 30.

[0068] Incidentally, instead of the double-acting hydraulic cylinder 38, the collection carrier 31 may be slid left and right by a rack and pinion operated by an electric motor.

[0069] FIG. 11 shows an embodiment in which the recovery carrier 31 is rotated outward by a double-acting hydraulic cylinder 39 instead of the configuration in which the recovery carrier 31 is moved left and right on the side carrier 32 by the double-acting hydraulic cylinder 38 described above.

[0070] That is, the tip of the piston 39a of a double-acting hydraulic cylinder 39, the base of which is fixed to the threshing frame 6a inside the body of the threshing device 6, is connected to the upper part of the inner wall 31c of the recovery carrier 31, a pivot axis in the fore-and-aft direction is provided at the front of the bottom surface 31a of the recovery carrier 31 so that the recovery carrier 31 can be freely tilted toward the outside of the body, and a pedal 40 for operating the double-acting hydraulic cylinder 39 is provided at the front of the side carrier 32 behind the control unit 7.

[0071] Therefore, when the rice bag placed on the recovery carrier 31 is filled with rice grains by receiving the grains discharged from the funnel portion 30a of the hopper 30, the worker operates the pedal 40 to extend the piston 39a of the double-acting hydraulic cylinder 39, and the recovery carrier 31 tilts toward the outside of the machine body. Therefore, the worker can easily move the rice bag placed on the recovery carrier 31 onto the side carrier 32 and lower it toward the outside of the machine body easily and with good workability.

[0072] Then, the worker operates the pedal 40 to retract the piston 39a of the double-acting hydraulic cylinder 39, returning the emptied recovery carrier 31 to a position below the funnel portion 30a of the hopper 30, and places the empty rice bag on the recovery carrier 31 to resume the grain recovery operation in the hopper 30.

[0073] In addition, a backrest 41 on which an operator who works while riding on the side carrier 32 can lean is provided on the side carrier 32. The backrest 41 is provided long in the front-rear direction at the tip of an arm 41a whose base is rotatably supported on the machine body, and its posture can be freely changed between an active state where it is positioned on the side carrier 32 and a stored state where it is folded inside the machine body.

[0074] Therefore, instead of the pedal 40, a sensor may be provided at the base of the arm 41a of the backrest 41, so that when the backrest 41 is in an active state where it is positioned on the side carrier 32, the piston 39a of the double-acting hydraulic cylinder 39 is contracted to position the recovery carrier 31 below the funnel portion 30a of the hopper 30, and when the backrest 41 is in a folded, stored state inside the body of the aircraft, the piston 39a of the double-acting hydraulic cylinder 39 is extended to tilt the recovery carrier 31 toward the outside of the aircraft.

[0075] The side carrier 32 may be made of a mesh material such as expanded metal to provide an anti-slip function for the worker, thereby enabling safe work.

[0076] In addition, the collection carrier 31 may be disposed at a position higher than the side carriers 32 so that a rice bag filled with grains can be placed below the collection carrier 31.

[0077] 12 and 13 show an embodiment in which the sun visor 50 is supported by the hopper 30. In FIG.

[0078] That is, a sun visor 50 that covers the upper part of the operation section 7 having the operation seat 7a is provided on a sun visor support frame 51 whose base is fixed to the upper surface of the hopper 30.

[0079] Therefore, a vertically long support frame erected from the aircraft frame 1 for mounting the sun visor 50 is not required, resulting in a simple, inexpensive and lightweight structure.

[0080] In addition, the two funnel portions 30a, 30a of the hopper 30 are provided with bellows hoses 30b, 30b, which facilitate filling the rice bags with grains. [Explanation of symbols]
