Towed, suspended and assembled duplex sweet potato transplanting machine capable of carrying water

Abstract

The invention relates to a towed, suspended and assembled duplex sweet potato transplanting machine capable of carrying water and belongs to the technical field of agricultural planting machinery. The machine comprises a rotary-tillage, ridge-forming and transplantation combined operation machine consisting of a transplanting unit and a rotary-tillage and ridge-forming unit, wherein a three-point suspension mechanism in linkage with a tractor is arranged at the front end of the frame of the combined operation machine. The towed, suspended and assembled duplex sweet potato transplanting machine is characterized by further comprising a water carrying platform which can be towed to move, the water carrying platform comprises a platform support with the rear end supported on bottom rolling wheels, a trailing frame connected with the rear-end towing point of the tractor is mounted at the front end of the platform support, and a circular-arc-shaped track support extending downwards is fixed under the middle of the platform support; a circular-arc-shaped limiting track extending upwards is fixed to the middle of the machine frame of the combined operation machine, and the track support and the limiting track are mutually connected in an inserted mode to form an arc movement pair with the swing center of the three-point suspension mechanism as the center of a circle. The towed, suspended and assembled duplex sweet potato transplanting machine achieve smooth operation and turning under the condition that enough water is carried, and the water carrying problem of the prior art is solved properly.

Description

technical field [0001] The invention relates to rotary tillage, ridging, and transplanting equipment for bare sweet potato seedlings, in particular to a traction-suspension assembled type water-sitable sweet potato compound transplanter, which belongs to the technical field of agricultural planting machinery. Background technique [0002] Usually, sweet potatoes are propagated asexually by root tubers. The seedlings are raised in the seedbed first, and then the seedlings are cut (pulled) and transported to the field for transplanting. They are mainly planted in high ridges, and the ridge height is about 25-33 cm. In addition, sweet potatoes need to be watered immediately after planting in the field, otherwise they will not root or die due to drought. [0003] According to the applicant's knowledge, the shallow rotation of the rotary tiller is widely used in my country for land preparation. Although the height of the sweet potato can reach 25-28cm, the height of the ridge wil...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the search that the Chinese patent application number 201410087640.0 provides a combined operation machine for sweet potato rotary tillage, ridging and transplanting. This machine is composed of a transplanting unit and a rotary tillage and ridging unit. Forming, stubble crushing and stubble breaking, ditching and seedling opening, seedling suppression, ridge repairing and ridge repairing operations, and properly solved many technical problems such as residue accumulation, maintaining ridge shape after transplanting, etc., thereby significantly improving the efficiency of mechanical planting of sweet potatoes and ensuring improved the quality of work, but failed to overcome the above-mentioned water-carrying problems
