Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention cuts and threshes culms, stores the grains pumped by a lifting cylinder of a threshing device in a grain tank, and pumps this. Various equipment arranged to be discharged to a transport vehicle etc. by a cylinder, and rotating the grain tank and arranged between the grain tank and the threshing device,
Alternatively, the present invention relates to a grain processing device in a combine that can maintain and inspect the threshing device.

(B) Conventional technology Conventionally, a combine was provided with a fuel tank below the driver's seat so that the fuel can could be injected into the fuel tank on a step, and a grain provided on the side of the threshing device. There is already known a combine in which a grain tank is tilted to form a space for performing maintenance and inspection with a threshing device.

(C) Problems to be solved by the invention In general, the combine has a heavy pretreatment device mounted in front of the machine body, so that there is a problem that the center of gravity of the machine body is in the front side. To solve the problem, if a fuel tank in a known combine is installed at the rear of the airframe, for example, at the rear of the grain tank, there is no suitable member for supporting the fuel can in this vicinity, and it is lifted by hand. The fuel must be replenished in a closed state, which causes new problems.

Further, when the grain tank is rotated to form a working space between the grain tank and the threshing device, the working space is formed at the back side of the grain tank so that the working space is visually recognized and the work is performed. Therefore, it was difficult to enter the working space.

(D) Means for Solving the Problems The present invention has a threshing device mounted on one side of a traveling platform and rotatably supporting a grain tank on the other side, and is close to the rear part of the grain tank. In a combine in which a lifting cylinder for discharging the grains in the grain tank is erected at the selected portion, and a pretreatment device is attached to the front part of the threshing device 3 so as to be able to move up and down, the grain of the lifting cylinder is A fuel tank is provided in the lower part on the tank side, and its injection port is opened in the vicinity of the lifting cylinder, and a protrusion having a flat upper surface is provided on a side portion of the lifting cylinder and a portion corresponding to the above-mentioned charging port. As a result, the above-mentioned problems are solved.

(E) Action When refueling, the cap of the inlet near the lifting cylinder is removed, and the fuel can is placed on the upper surface of the protrusion protruding from the lifting cylinder for refueling.

In addition, when servicing equipment such as a device installed between the threshing device and the grain tank, a traveling device, a pretreatment device, a transmission system thereof or a sorting unit of the threshing device, the grain tank is rotated to perform the threshing. When a working space is formed between the device and the grain tank and the work space is visually recognized by climbing up to the protrusion protruding from the lifting cylinder, it is possible to immediately check the condition of the equipment such as the transmission device. If the maintenance is required, the protrusion can be used as a scaffold to easily enter the working space.

(F) Embodiments An embodiment of the present invention will be described with reference to the drawings. A self-extracting threshing device 3 is mounted on one side of a machine base 2 having a traveling device 1, and a grain tank 5 is mounted on the other side. It is mounted on the front of the threshing device 3 from a reaping device consisting of a grain culm raising device and a cutting blade, and a grain culm transporting device for nipping and transporting the harvested grain culm backward and supplying it to the threshing device 3. The pretreatment device 6 is attached so that it can be moved up and down.
A control panel 9 is also provided.

Further, the grain tank 5 has a bottom plate having a V-shape when viewed from the front-rear direction, and a transport spiral for transporting and discharging the stored grain backward is horizontally installed at a lower portion thereof, and this transport is performed. Spiral axis
The V-pulley 11 mounted on the shaft 10 is supported so as to be able to rotate outward as shown in FIG.
It is driven by 13 via a V-belt.

Further, the lifting cylinder 15 is erected on the upper surface of a holder 17 screwed onto a gear case 16 which also serves as a relay case, and the rear end of the transfer spiral is connected to the relay case via a transfer cylinder 18 in the front-rear direction. The auger 19 connected to the lifting tube 15 by being connected to the upper part of the auger 19 is connected to the upper part thereof so that the auger 19 can be laid up forward during the mowing and threshing work, and leads to the most trough of the threshing device 3. The discharge part 20a attached to the upper part of the fried grain cylinder 20 communicates with the inlet 21 provided on the upper part of the grain tank 5.

A fuel tank 22 is provided on the rear side of the V-shaped bottom plate of the grain tank 5 and on the side of the threshing device 3, and an injection port 23 thereof projects between the holder 17 and the grain tank 5. It has a cap 25.

Further, a protrusion 26 having a substantially horizontal upper surface is integrally provided at a portion of the outside of the holder 17 slightly lower than the injection port 23, and the cover 27 protrudes outward from the rear surface of the lifting tube 15. Attached to the hinge 28 in a freely openable and closable manner, the upper side of the outer end of the protrusion 26 is covered upward, and the vertical pin 29 protruding from the inner surface of the middle portion of the protrusion 26 is attached to the front of the lifting cylinder 15. It is fixed by being press-fitted into the integral spring holder 30.

Further, on the outer side of the upper portion of the lifting cylinder 15 and the upper surface of the rear side of the grain tank 5 near the threshing device 3, there are provided protrusions 31 and 32 for the operator to hold the protrusion 26 with one foot. I am doing it.
33 is a cutter.

In the above combine, the traveling device, the pretreatment device, the threshing device 3, or their transmission system, or the grain tank 5
When servicing the transmission system of, the grain tank 5 is tilted outward and locked, the cover 27 is opened, and one leg is hung on the protrusion 26 protruding from the lifting cylinder 15 to check the condition of the maintenance location. With the proper tool, the protrusion 26 is used as a scaffold to enter the work space between the grain tank 5 and the threshing device 3 for maintenance. Even when the maintenance work is finished and the work space goes outside, the protrusion
26 is used as a scaffold.

When fuel is injected into the fuel tank 22, the cover 27 is opened, the cap 25 of the injection port 23 is removed, and a part of the fuel can is projected.
Place on 26 and lubricate in that state. After that, the fuel can is lowered, the cap 25 is attached, and the cover 27 is closed.

Furthermore, since the fuel tank 22 that was conventionally located in front of the grain tank 5 is provided near the rear portion of the grain tank 5 during traveling, the front-rear balance of the machine body is improved.

(G) Effect of the invention Since the invention is configured as described above, the front-rear balance of the machine body is improved and stable traveling and threshing can be performed, and moreover, the fuel tank 22 is connected to the rear part of the grain tank 5. Despite being provided in the above, the refueling can be easily performed with the fuel can placed on the protrusion 26 provided outside the lower part of the lifting cylinder 15, and the grain tank 5 is tilted to remove the threshing. Device 3
When a worker enters the work space formed between the grain tank 5 and the grain tank 5, the protrusion 26 can be used as a scaffold to easily and safely enter and exit.
