Description

The present invention relates to a mud removing device for agricultural vehicles that removes mud adhering to a traveling portion.

In agricultural work using a tractor, such as rotary tillage work, a large amount of soil often adheres to the traveling part and the working machine. When traveling on the road surface in such a state, the soil adhering to the tires may be scattered on the road surface regardless of whether it is a wheel type or a track type, which may cause environmental pollution in the area and traffic safety problems. Especially in rural areas where residential land is becoming more and more residential, complaints from neighboring residents are likely to occur, which is a serious problem for producers. In addition, in vegetable cultivation, there are some areas where prevention of the spread of pathogens mixed in the soil is an issue. In recent years, according to the environmental beautification regulations of local governments, when soil, sludge, livestock excrement, etc. adhering to the tires of agricultural machinery fall on the road or its surroundings while driving, the producers and businesses are cleaned. There are some places that impose an obligation to try to restore the original condition. Against this background, the development of a mud removing device that removes mud adhering to the traveling portion of an agricultural vehicle is eagerly desired.
Under such circumstances, the following devices have been proposed.
Patent Document 1 discloses a device in which a crawler is floated from the ground by support members attached to the left and right sides of the vehicle body, and the crawler is rotationally driven to shake off mud adhering to the crawler.
Further, Patent Document 2 discloses a device capable of lifting one of the left and right traveling devices by a stand member and efficiently removing mud adhering to the traveling device.
Further, Patent Document 3 discloses a vehicle tire cleaner for removing mud adhering to wheels.

According to this embodiment, since the traveling unit 10 can be idled without modifying the agricultural vehicle 1, it is possible to quickly remove mud. Further, according to the present embodiment, the agricultural vehicle 1 can be mounted on the moving table 612 by self-propelling without jacking up, and can idle while maintaining the height on which the traveling unit 10 is placed. It has excellent workability and can perform stable idling.
Further, in the mud removing device 600 of the agricultural vehicle 1 according to the present embodiment, both the traveling portion 10F on the front wheel side and the traveling portion 10B on the rear wheel side can be in an idling state, and the mud removal workability is excellent and stable. Can slip.
Further, in the mud removal device 600 for agricultural vehicles according to the present embodiment, since the height changing member 612e is used as an air mat, a gap is formed between the moving table mounting surface 612a and the traveling portion 10 by introducing and discharging gas. can do.
Further, in the mud removal device 600 for agricultural vehicles according to the present embodiment, the height on which the traveling portion 10 is placed is stabilized by attaching the locking portion 621 to the axle case 4 that rotatably supports the drive shaft 2. Can be maintained in a state.

The locking portion receiving member 12c described in the agricultural vehicle mud removal device 400 according to the fourth embodiment of the present invention may be applied to the first to third embodiments and the sixth embodiment. ..
Further, the configuration in which the locking portion 221 is attached to the lower link 3 described in the agricultural vehicle mud removal device 500 according to the fifth embodiment of the present invention is applied to the first to third embodiments and the sixth embodiment. It may be applied.
Further, the configuration in which the locking portion 621 is attached to the axle case 4 described in the agricultural vehicle mud removal device 600 according to the sixth embodiment of the present invention may be applied to the first to fifth embodiments.

The mud removal device for an agricultural vehicle of the present invention is not limited to a tractor for towing an agricultural machine or the like, and can be widely applied to a vehicle having a tire and / or a crawler as a traveling unit.
