Pit-digging apparatus convenient for moving

Abstract

The invention discloses a pit-digging apparatus convenient for moving. The pit-digging apparatus comprises a vehicle frame and a driving motor, a transverse slat is arranged at the vehicle frame, thetransverse slat is fixedly connected with a soil sampling barrel, a spiral blade is arranged in the soil sampling barrel, a rotation roller is fixedly connected with the spiral blade, a threaded rod is fixedly connected with the rotation roller, the threaded rod passes through the soil sampling barrel, and a screw sleeve is fixedly connected with at center position of the top of the soil samplingbarrel. An internal spline shaft and an external spline sleeve are arranged, cooperation of the internal spline shaft and the external spline sleeve drives the spiral blade to downwardly rotate, soilcan be dug, the structure is simple, dissipating energy is less, the soil sampling barrel and a soil-discharge pipe are arranged, the soil is dug and then raised, the accumulated soil is discharged, splash and diffusion of the soil can be avoided, anaphase refilling is convenient, and plantation efficiency is increased. The vehicle frame and a fixed plate having conical tooth are provided, and themobility and stability of the pit-digging apparatus are increased.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to a portable digging device. Background technique [0002] The pit digging machine is a special machine for fast digging of pits for afforestation and fertilization in mountains, hills, and gullies. The digging machine frees people from heavy physical labor and is widely used in afforestation, planting fruit forests, fences, and fertilizing fruit trees in autumn. It has strong power, beautiful appearance, comfortable operation, low labor intensity, suitable for various terrains, high efficiency, and convenient for field operations. [0003] The digging device of the traditional digging machine is to use the spiral blade roller to dig the hole. After the soil is excavated, the soil will be scattered to the periphery of the pit along with the spiral blades, and a certain amount of splash will be generated. When backfilling, it needs to be collected again. The soil is time-consumin...

Problems solved by technology

[0003] The digging device of the traditional digging machine is to use the spiral blade roller to dig the hole. After the soil is excavated, the soil will be scattered to the periphery of the pit along with the spiral blades, and a certain amount of splash will be generated. When backfilling, it needs to be collected again. The soil is time-consuming and reduces the efficiency of planting; in addition, the traditional digging device uses hydraulic cylinders or chains and other lifting devices to control the height of the helical blades, and drives the helical blades to rotate through motors or diesel engines. can be more
