Tiller

Abstract

The invention discloses a mini tiller. A fixed base is arranged on the top of a mini tiller body. A radial bearing is arranged on the upper portion of the fixed base; a rotating disc is arranged above the fixed base in a spaced manner; a bearing cap is arranged at the bottom of the rotating disc, and a thrust bearing is arranged in the bearing cap; a connecting shaft is arranged in the radial bearing and the thrust bearing; the upper end of the connecting shaft is in interference fit with the rotating disc, and a connecting disc is arranged on the connecting shaft in an interference fit manner; a bucket cylinder is arranged on an auxiliary arm joint side pipe, and a first connecting plate and a second connecting plate are hinged to a third piston rod of the bucket cylinder at the same time; the other end of the first connecting plate is hinged to an auxiliary force arm; and the other end of the second connecting plate is hinged to a bucket. According to the invention, the mini tiller can carry out working in places such as a garden, a greenhouse and terraced fields under the condition that farmland is not damaged, and excavation strength is high; and the manufacturing cost is reduced, and the mini tiller has the beneficial effects of saving cost, reducing work intensity, improving the excavation efficiency and the like.

Description

technical field [0001] The invention relates to a tiller. Background technique [0002] Tillers currently on the market are mainly used for rotary tillage in orchards, greenhouses, terraces, slopes, etc., but cannot perform earthwork excavation, land leveling, ditching, etc., and can only be operated manually and with large excavators. However, On the one hand, manual work is inefficient; on the other hand, it increases people's labor intensity. [0003] While working with a large excavator, on the one hand, a large excavator consists of a variety of parts such as a power unit, a working device, a control mechanism, a transmission mechanism, a walking mechanism, and auxiliary facilities, which leads to high prices, and ordinary farmers cannot afford the cost; On the other hand, large excavators are generally used in large-scale operations such as hoisting, crushing, demolition, road construction, railway construction, bridge construction, urban construction, airport port an...

Problems solved by technology

[0002] Tillers currently on the market are mainly used for rotary tillage in orchards, greenhouses, terraces, slopes, etc., but cannot perform earthwork excavation, land leveling, ditching, etc., and can only be operated manually and with large excavators. However, On the one hand, manual work is inefficient; on the other hand, it increases people's labor intensity

[0003] While working with a large excavator, on the one hand, a large excavator consists of a variety of parts such as a power unit, a working device, a control mechanism, a transmission mechanism, a walking mechanism, and auxiliary facilities, which leads to high prices, and ordinary farmers cannot afford the cost; On the other hand, large excavators are generally used in large-scale operations such as hoisting, crushing, demolition, road construction, railway construction, bridge construction, urban construction, airport port and water conservancy construction, etc. Stone excavation, land leveling, ditching and other operations of small projects will cause unnecessary waste of resources; secondly, large excavators are bulky, and it is difficult to drive to orchards, greenhouses, terraces, etc. It will also cause a lot of damage to the field

[0004] In view of this, people reduce the ratio of all aspects of large excavators, so that the entire volume of large excavators is reduced, and excavators have been realized in orchards, greenhouses, terraces and other places for small projects such as stone excavation, land leveling, ditching, etc. However, on the one hand, due to the reduction of the entire volume of the excavator, the strength and excavation force of each part of the excavator are reduced; on the other hand, converting a large excavator into a small excavator is not only troublesome but also expensive
