Rotary seedling-transplanting hole-digging machine

Abstract

A rotary seedling-transplanting hole-digging machine comprises a handgrip and a main rack. The main rack is a frame structure, which is externally coated with a protective shell. A transverse shaft is welded at the rear end inside the main rack. The transverse shaft passes through a wheel body, which is composed of a center bearing and back shafts. The back shafts are arranged on the outside of the center bearing. The back shafts are hollow and radiated at the outer side of the center bearing. The lower part of each back shaft is provided with a column base adjusting bolt. The lower end of each back shaft sleeves a telescopic column base, which is fixed by turning and tightening the column base adjusting bolt. The lower end of each telescopic column base is provided with a column base support. A soil sampling sleeve and a soil mass dialing piece are arranged at the opposite side of the corresponding column base support. The soil mass dialing piece is arranged on the telescopic column base at the side of the soil sampling sleeve. The Rotary seedling-transplanting hole-digging machine can rapidly dig soil holes and can control depth consistency of the soil holes and can make the spacing between crops to be equalized. In comparison with traditional manual hole-digging, the invention has the following advantages: manpower and material resources are saved.

Description

technical field [0001] The invention relates to agricultural planting machinery, in particular to a rotary seedling transplanting machine. Background technique [0002] In the seedling stage of crops, it is necessary to move the soil for cultivation, and to increase the yield of crops regularly through measures such as transplanting seedlings and filling seedlings. In the prior art, there are two methods for digging holes in soil-moving cultivation. One is to use a hydraulically driven hole-digging machine installed on a tractor. However, this method is costly, and it will cause land for crops due to the rolling of the land by the tires of the tractor equipment. The ground is uneven, and the post-processing is time-consuming and difficult; one is to use manual digging, but relying on manpower to use tools to dig holes, the operator's operation is random, the operation accuracy is poor, and the error is large, resulting in different depths and distances of soil holes High st...

In the prior art, there are two methods for digging holes in soil-moving cultivation. One is to use a hydraulically driven hole-digging machine installed on a tractor. However, this method is costly, and it will cause land for crops due to the rolling of the land by the tires of the tractor equipment. The ground is uneven, and the post-processing is time-consuming and difficult; one is to use manual digging, but relying on manpower to use tools to dig holes, the operator's operation is random, the operation accuracy is poor, and the error is large, resulting in different depths and distances of soil holes High strength, low efficiency, time-consuming and labor-intensive

Chinese patent 201210546078.4 discloses a hole-digging and spot-fertilizing machine, but it is mainly used for fertilizing crops, and the soil hole dug by it is relatively large, which is not suitable for transplanting seedlings and cultivation, and it cannot be used for seedling replenishment because it is a four-wheel machine as a whole. farmland
