A kind of hole digging device for fruit tree cultivation

Abstract

The invention discloses a hole digging device for fruit tree cultivation. The hole digging device comprises a fixed casing pipe, wherein a first threaded rotating rod is inserted into the top of the fixed casing pipe, and the surface of the first threaded rotating rod is in threaded connection with the top of the fixed casing pipe. According to the hole digging device for fruit tree cultivation, firstly, a support pipe and a drilling barrel drill the inside of soil simultaneously to a certain depth, then, a second threaded rotating rod rotates on the support pipe to push a sliding pipe to slide downwards according to the thread propelling principle, semicircular resistance plates on two sides are inserted into the soil transversely to increase friction between the support pipe and the soilby using the height displacement of the sliding pipe and the diameter difference of the sliding pipe, so that vertical support force provided by the soil for the fixed casing pipe is used, and then,the drilling barrel is driven to drill deep soil rock strata by using the reverse thread propelling principle of the first threaded rotating rod and the fixed casing pipe.

Description

Technical field [0001] The present invention relates to the technical field of agricultural cultivation equipment, and is specifically a tubing device for fruit trees cultivation. Background technique [0002] In the case of a low social productivity, people mainly rely on picking fruits, but the fruit is a biggest shortage for people's supply, which is a season of seasonality. Something, sometimes it is unfavorable, and there will be no these foods. Not only, wild fruit sometimes can't meet people's needs, this forces people to have a way to get rid of richer food, plus the growth of life production experience, and discover some fruit trees according to people It is necessary to grow reproduction, so people have begun to try wild fruit trees. [0003] At present, farmers need to first open the soil in the process of cultivating the fruit trees, burry the root of the fruit seedlings, due to the demand of different fruit trees, there is also a large depth in my country. Some of th...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a hole-digging device for fruit tree cultivation, which solves the problem that due to the stratification of terrain and soil, some soil is relatively hard, and because traditional shovel digging is time-consuming and laborious, and it also achieves The cultivation depth of the fruit tree seedlings is not enough, which brings some troubles to the fruit growers
