Agricultural pit digging machine

Abstract

The present invention discloses an agricultural pit digging machine, which comprises motor, a loading plate, a lifting oil cylinder, wheels, a hydraulic motor, a rotation shaft, stretching rods, a screw auger, an expansion rod and an alloy drilling bit, wherein a motor main shaft is fixedly connected above the middle of the loading plate, the motor is arranged above the motor main shaft, handles are arranged above the left end and the right end of the loading plate, the rotation shaft is arranged at the middle position just below the loading plate, the lifting oil cylinder circles around the rotation shaft and is fixedly connected below the loading plate, the stretching rods are arranged above the left end and the right end of the loading plate, the wheels are arranged below the stretching rods, the hydraulic motor is fixedly arranged below the rotation shaft, the middle-lower section of the stretching rod is provided with a snapping lock, the screw auger circles around the lower section of the rotation shaft, the expansion rod is arranged on the left end and the right end of the bottom of the rotation, and the alloy drilling bit is arranged below the rotation shaft. The agricultural pit digging machine of the present invention has characteristics of simple structure and strong practicality.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an agricultural digging machine. Background technique [0002] At present, with the increasing impact of the rapid development of science and technology on the environment, people are paying more and more attention to the protection of the ecological environment. Among them, seedling cultivation, afforestation and landscaping are important tasks for protecting the environment, and seedling digging machines are mainly used for tree planting. Cave-shaped soil preparation operations can also be used for digging topdressing holes or pits for burying piles. The nursery stock digging machine of prior art comprises tractor, gear box, universal joint drive shaft, suspension pull bar, rotary blade, cutter shaft, drill bit and belt, and tractor output shaft drives the universal joint drive shaft of gear box to rotate by belt, The drive shaft of the universal joi...

AI Technical Summary

Problems solved by technology

[0003] 1. The tractor as a power device is not suitable for hillsides or environments with small digging spaces, and the scope of application is small; during the excavation process, the cutter shaft often appears in a tilted state instead of a vertical state, resulting in uneven digging shape and low digging efficiency

[0004] 2. The tractor is controlled to stop according to the depth of the cutter shaft entering the pit, so that the depth of the seedling pit dug is quite different, resulting in a decrease in the survival rate of the seedlings
