Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a combine.

[0002]

2. Description of the Related Art In a combine harvester, a pre-cutting processing unit for causing a planted grain culm, cutting, transporting the cut grain culm to the rear of the machine and supplying it to a threshing apparatus is connected to the front of the traveling machine. For this reason, especially in the case of a small size, it may be difficult to balance especially the front and rear weight of the whole combine.
Conventionally, in this case, the threshing device and the threshing grain collecting unit are mounted on the traveling machine body in a rearward direction to balance the front and rear weight.

[0003]

Heretofore, there has been a case where the front and rear length of the entire combine becomes long due to the backward movement of the threshing apparatus and the threshing grain collecting section. An object of the present invention is to provide a combine that can balance the front and rear weights while preventing the entire combine from becoming longer and heavier and preventing the occurrence of trouble.

[0004]

The constitution, operation and effect of the invention according to claim 1 are as follows.

[Structure] An engine fuel tank and a battery are arranged on the side of the threshing grain collecting section at the rear end of the traveling machine body so that the battery is disposed closer to the threshing grain collecting section than the engine fuel tank. A combine where the fuel pump that supplies fuel to the engine is located between the engine fuel tank and the battery.

[Operation] Since the engine fuel tank and the battery are located at the rear end of the traveling body, the weight of the engine fuel and the battery is applied to the rear end of the traveling body. This makes it possible to minimize the backward movement of the threshing grain collection unit and threshing device, as well as to move the threshing unit and threshing device to the rear side and to adopt a special balance weight. The weight before and after the entire combine can be balanced while suppressing the increase in weight. Since the battery is located closer to the threshing unit than the fuel tank, the space below the bagging hopper can be used for checking and loading / unloading the battery if the threshing unit is a bag type. Therefore, in the case where the threshing and grain collecting unit is a tank type, the tanks can be easily formed from the spaces formed by operating the tank to the lateral outside of the machine body. By locating the fuel pump between the fuel tank and the battery, the fuel pump can be connected as close as possible to the fuel tank, and the fuel pump can efficiently supply fuel from the fuel tank to the engine. Moreover,
When the threshing grain collection unit is a bag-packed type and a grain bag is put in and out, or when the threshing grain collection unit is a tank type and put out to the outside of the machine for inspection, the battery is connected to the fuel pump. It becomes a guard member, which makes it easier to avoid a situation in which a hand or the like touches the fuel pump.

[Effect] By using the weights of the engine fuel and the battery for the balance weight, it is possible to balance the front and rear weights while suppressing an increase in the overall length and weight of the entire combine, and obtain an advantageous effect such as easy steering. . In addition, the battery can be inspected and removed relatively easily, and the fuel pump can be efficiently supplied with fuel and not easily damaged.
Maintenance management and engine driving can be advantageously performed.

The structure, operation and effect of the invention according to claim 2 are as follows.

[Structure] In the structure of the invention according to claim 1, a cover for covering the battery is provided.

[Operation] Even if fuel leaks, such as when the fuel pump is checked, the cover covers the battery, making it difficult to adhere to the battery.

[Effect] Inspection work can be performed while easily avoiding a situation where fuel leaks and adheres to the battery.

The structure, operation and effect of the invention according to claim 3 are as follows.

[Constitution] In the constitution of the invention according to claim 2, the cover is attached so as to be switchable between a state covering the battery and a state covering the fuel pump.

[Operation] When checking the fuel pump, the cover can be set to the original battery cover state so that even if a fuel leak occurs, it is difficult to adhere to the battery. In this case, when the vehicle is to be put on and off, by switching the cover to the state of the fuel pump cover, it is possible to prevent the pump from being affected even if a spark is generated.

[Effect] When checking the fuel pump or the like, it is possible not only to work while avoiding the leaked fuel from adhering to the battery, but also to check the battery or remove the fuel from the battery. Work can be performed without affecting the fuel pump.

The structure, operation and effect of the invention according to claim 4 are as follows.

[Configuration] In the configuration of the present invention according to any one of claims 1 to 3, a partition member is disposed between the fuel pump and the battery.

[Operation] When checking the fuel pump, etc.,
Even if fuel leaks, the partition member prevents the fuel from flowing to the battery side.

[Effect] When the fuel pump is inspected or the like, the operation can be performed while preventing the leaked fuel from flowing to and adhering to the battery side.

The structure, operation and effect of the invention according to claim 5 are as follows.

[Structure] In the structure of the present invention according to claim 4, a pump mounting portion for supporting the fuel pump is provided on the partition member.

[Operation] The partition member is used as a support member,
The fuel pump is mounted without the need for a special support member.

[Effect] The fuel pump can be mounted with a simple structure that does not require a special support member, and the fuel pump can be advantageously obtained in terms of cost.

The structure, operation and effect of the invention according to claim 6 are as follows.

[Structure] In the structure of the invention according to any one of claims 1 to 5, the threshing grain collecting section collects threshing grain in a grain bag by a bag hopper.

[Operation] When the fuel pump or the battery is inspected or loaded or unloaded, the space for placing the bag below the bagging hopper can be used as a working space.

[Effect] When checking or removing the fuel pump and the battery, the space for bagging can be used as a work space, and work can be performed easily and efficiently.
