Automatic pit digging and soil making machine

Abstract

The invention discloses an automatic pit digging and soil making machine. The machine comprises a machine body, a knife rest, a pit digging knife arranged on the knife rest and a driving mechanism fordriving the pit digging knife to drill holes, the pit digging knife is covered with a protective cover which is fixedly connected with the knife rest and used for preventing stone chips from splashing, and the machine body is provided with a plurality of material boxes. The material boxes communicate with the interior of the protective cover through feeding pipes, and the feeding pipes are provided with feeding valves. As the pit digging knife is covered with the protective cover, the stone chips generated by rapid rotation of the pit digging knife are blocked by the protective cover, and splashing of the stone chips is prevented; meanwhile, after pit digging is completed, the feeding valves are opened, so that added materials in the material boxes enter the protective cover through the feeding pipes, the stone chips in the protective cover and the added materials are mixed to form soil for planting trees under the action of rotation of the pit digging knife, and therefore the steps of pit digging in a soil layer with large stone blocks and large soil making amount are completed; and the processes of manual hole digging and soil conveying are omitted, and the manual investment ofhole digging operation is reduced.

Description

technical field [0001] The invention relates to the technical field of garden equipment, in particular to an automatic digging soil making machine. Background technique [0002] As one of the important projects at this stage, the greening project has attracted much attention all over the world. Tree planting is widely used as a common means of greening. Tree planting methods include sapling planting, tree transplanting and other means, but no matter which method is used, before tree planting, a process of digging holes is required to prepare for trees, and the soil layers for tree planting are also various. Such as loess layer, clay layer, soil layer containing pebbles and gravel, rock layer and so on. Most of the original digging work is done manually, which consumes a lot of labor costs. [0003] In order to free people from heavy physical labor and reduce the labor consumption of tree planting, pit digging machines came into being. A kind of tree planting pit digging ...

Problems solved by technology

[0004] But in the prior art, the digging knife of the digging machine is only a spiral blade, mostly for sandy soil, loess or the soil layer containing pebble gravel, the rotation speed of the digging knife is not slow, for the soil layer containing large stones, does not apply

If you want to dig a hole in the soil layer with large stones, you need to be able to break the large stones, and most of the digging knives of the existing digging machines have low speeds, which cannot meet the requirements for breaking large stones. To meet the requirements, the process of breaking stones will also produce flying stone chips, which may easily cause safety accidents. Therefore, digging pits in soil layers with large stones still requires manual digging and soil transportation, which will still take up a lot of time. artificial
