Small-scale micro tillage machine with composite walking wheels

Abstract

The invention discloses a small-scale micro tillage machine with composite walking wheels. An engine is located in the middle part of a machine frame, a gear gearbox is obliquely arranged in the manner of being low in the front and high in the rear, the output end of the gear gearbox is connected with the middle part of a wheel shaft, and the walking wheels are installed at two ends of the wheel shaft; and each walking wheel includes a wheel rim and a wheel hub, radial convex tables are uniformly distributed on the outer circumferential surface of each wheel rim, a steel skeleton covers the interior of each wheel rim, each steel skeleton is provided with reinforcement structures uniformly distributed along the circumference, each wheel hub is located in the center position of one corresponding wheel rim, and a plurality of wheel spokes uniformly distributed along the circumference are arranged between each wheel hub and one corresponding wheel rim. The machine provided by the inventionhas reasonable arrangement, and is easy to assemble, a gravity center of the whole machine is centered, and the operation is more convenient and more labor-saving; the machine can reduce a rolled area of the ground, increase the ground gripping force, avoid idling and ridge running phenomena in land ploughing operation, and ensure the high farming efficiency through the additional arrangement ofthe radial convex tables and edge convex tables while reducing widths of the wheel rims; and the walking wheels of the machine have good supporting strength, and are durable in use in harsh environments such as muddy roads.

Description

technical field [0001] The invention belongs to the field of miniature cultivators of agricultural machinery, and in particular relates to a miniature cultivator with compound traveling wheels. Background technique [0002] With the vigorous support and development of agricultural mechanization, the use of tillage machines is becoming more and more extensive. Due to the characteristics of light weight, small size, simple structure, and convenient operation, the tiller is suitable for the cultivation of sloping land and small pieces of land in the vast hilly and mountainous areas of our country, and is deeply loved by the majority of users. [0003] At present, the walking wheels of micro tillage machines generally use wide rubber wheels, which have a large contact area with the ground and are easy to compact the ground, which is not conducive to the root growth of crops. Simultaneously, the gripping effect of the traveling wheels of the existing micro tillage machine is not...

AI Technical Summary

Problems solved by technology

[0003] At present, the walking wheels of micro tillage machines generally use wide rubber wheels, which have a large contact area with the ground and are easy to compact the ground, which is not conducive to the root growth of crops.

At the same time, the walking wheels of the existing micro tillage machine do not have a good grip on the ground, and it is easy to idling and run away when the force is applied during the operation of the cultivated land, which limits the utilization rate of the micro tillage machine on sloping land

Some micro tillage machines add ground claws on the outer circumference of the walking wheel. Although the grip is increased, the ground claws are mostly wedge-shaped. On the one hand, they are prone to damage when encountering hard objects such as stones. resistance, making the operation more laborious, thus reducing the farming efficiency

[0004] Some micro tillage machine walking wheels adopt metal structure, including steel ring, hub installed in the steel ring and leaves installed on the periphery of the steel ring. It is easy to cause damage to the steel ring due to overload; and the processing technology of this all-metal structure travel wheel is complicated, the cost is high, and the relative rotation between the hub and the axle is easy to occur, and the reliability is poor

[0005] In addition, the power assembly of the micro tillage machine is usually arranged at the rear of the frame, which causes the rear of the whole machine to be heavy. When operating, it is necessary to lift the handrail to carry out the operation. The labor intensity of the operator is high, and fatigue is easy to occur. The center of gravity is shifted backward, and the layout of the engine, gear box, etc. is unreasonable
