Pit digging device for fruit tree planting

Abstract

The invention discloses a pit digging device for fruit tree planting. The pit digging device comprises a case, a motor box, handles, a control cabinet, a support, support legs, a drill pipe, support columns, springs, a hydraulic pump, a spring telescopic rod, hydraulic telescopic rods, a support disc, a bottom sleeve, a drill bit, a joint, a connecting pipe and a through hole. According to the pitdigging device for fruit tree planting, multiple support columns are arranged in the case, so that the whole structure of the inside of the case is more stable; multiple springs are mounted between the case and the support and can play shock absorbing and pressure reducing roles during operation of the device, thus, the stability of the device during operation can be effectively guaranteed. The hydraulic pump is mounted at the bottom of the drill pipe, two hydraulic telescopic rods and the hollow spring telescopic rod between the two hydraulic telescopic rods are connected with the bottom ofthe hydraulic pump, the bottom of the hydraulic telescopic rod is connected with the support disc, the hollow bottom sleeve is mounted at the bottom of the support disc, and the drill pipe penetratesthrough the hydraulic pump, the spring telescopic rod and the bottom sleeve.

Description

technical field [0001] The invention relates to a pit opening device, in particular to a pit opening device for planting fruit trees, and belongs to the field of fruit tree cultivation. Background technique [0002] Before fruit trees are planted, pits need to be dug. Existing methods of digging pits often use manual digging. The site is extremely prone to landslides that have just been excavated here, causing the potholes to be filled with the collapsed soil, and the efficiency of manual excavation is extremely low and the cost is also high. Contents of the invention [0003] (1) Solved technical problems [0004] The purpose of the present invention is to solve the problem that the above-mentioned existing means of opening pits often adopts the manual digging method, which is not only time-consuming and laborious, but also has different sizes and depths of the pits dug out, and it is difficult to find the holes when the soil is loose. The site is extremely prone to pro...
