Sweet potato rotary tillage ridging transplanting combined operation machine

Abstract

The invention relates to a sweet potato rotary tillage ridging transplanting combined operation machine suitable for transplanting an exposed sweet potato seedling, and belongs to the technical field of agricultural planting machinery. The combined operation machine comprises a transplanting unit and a rotary tillage ridging unit which are connected by a connection frame; the outside of traction plates, forwards extending, at two sides of the middle of a horizontal main rod of the connection frame is fixedly connected with a rotary tillage unit; a pair of traction plates downwards extend to a stubble pressing disc; a ground wheel assembly at the front side of the transplanting unit is provided with a transmission shaft in transmission connection with a power input end of the transplanting unit; a working chain wheel is arranged at one side of the ground wheel; the working chain wheel is in transmission connection with a driven chain wheel on the transmission shaft by a chain; a ridge repairing assembly is arranged at the rear side of the transplanting unit; a pair of splayed soil collecting discs are hinged to a support member of the ridge repairing assembly; each disc supports a roller. Stubble pressing and stubble damaging operations can be reliably finished by the sweet potato rotary tillage ridging transplanting combined machine, the ground wheel assembly works from a furrow without damaging the ridge form, and the ridge repairing assembly can automatically finish the soil ridging, ridge smoothening and ridge repairing works after the transplantation.

Description

technical field [0001] The invention relates to a rotary tillage, ridging and transplanting equipment, in particular to a rotary tillage, ridging and transplanting combined operation machine suitable for planting bare sweet potato seedlings, and belongs to the technical field of agricultural planting machinery. Background technique [0002] Sweet potato is a crop planted on high ridges (the ridge height is about 30cm) and transplanted from bare seedlings. A trapezoid with a relatively small top width. [0003] According to the applicant's understanding, due to the limitation of existing agricultural machinery, sweet potato planting generally needs to use a rotary tiller to prepare the land, then use a ridger to form ridges, and then use a transplanter to plant and suppress. The main common problems are: ①There are many planting procedures, and the tractors need to go to the field for many times, resulting in low efficiency and high energy consumption; ②Traditional transplan...

AI Technical Summary

Problems solved by technology

The main common problems are: ①There are many planting procedures, and the tractors need to go to the field for many times, resulting in low efficiency and high energy consumption; ②Traditional transplanting machines tend to cause long residues to accumulate when planting sweet potatoes in wheat stubble fields or winter fallow fields On the ditch opener, the ridges were pushed and could not be planted; ③After the traditional transplanting machine was planted, the top of the ridge was severely crushed and damaged, and the body of the ridge was collapsed and deformed, requiring manual or mechanical secondary repairs, which was labor-intensive and time-consuming; ④ At present, the track distance of the front and rear wheels of the tractor is poorly matched with the ridge spacing of the sweet potato planting ridge. Although many tractors can complete the rotary tillage and ridge operation, it is difficult to complete the transplanting operation due to the lateral pressure on the ridge body, resulting in 50- Idle or underutilized tractors in the 85 hp range

[0004] The search found that Chinese patents with application numbers of 201220392762.7, 201210260158.3, 201110231283.7, 200820036334.4, 200720035047.7, and 200720150985.1 respectively disclose transplanters with various typical structures, but these existing technologies cannot simultaneously realize rotary tillage, land preparation, and soil building The operation of crushing stubble, ditching and releasing seedlings, suppression, and repairing ridges cannot meet the actual needs of many aspects of sweet potato planting.

[0005] In particular, as far as the applicant knows, when various existing technologies encounter the problem of long stubble gathering on the ditching utensils during the planting of sweet potatoes, they cannot actually get rid of the entanglement, and it is very easy to have consequences such as pushing ridges, resulting in failure to plant. Continuously, and there is no automatic repair method for the collapse and deformation of the top of the ridge after planting, which seriously affects the quality of sweet potato planting

[0006] Therefore, the prior art has restricted the efficiency and operation quality of sweet potato mechanical planting, and caused waste or low utilization rate of existing power resource allocation
