Semi-automatic selenium sand melon transplanter

Abstract

The invention discloses a semi-automatic selenium sand melon transplanter. The semi-automatic selenium sand melon transplanter comprises a rack, a seedling casting device, a ditching device, a soil covering device and a soil gathering and seedling protecting device, wherein the front end of the rack is provided with a traction frame, and two sides of the rack are provided with traveling wheels; the seedling casting device is arranged on the upper side of the rack and located behind the traction frame; the seedling casting device comprises a seedling casting pipe vertically fixed to the rack; the ditching device is arranged on the lower side of the front end of the rack; the soil covering device is arranged on the lower side of the rack and located behind the ditching device; the soil gathering seedling protecting device comprises a soil gathering frame, an electric push rod, an auxiliary switch, a PLC and a power supply; the soil gathering frame is erected on the upper side of the rack and located behind the soil covering device, the electric push rod is connected between the rack and the soil gathering frame and can drive the soil gathering frame to move up and down relative to the rack, the auxiliary switch is arranged on the seedling casting pipe and executes an automatic touching action in the downward moving process under the action of the gravity of melon seedlings, and the PLC is electrically connected with the electric push rod, the auxiliary switch and the power supply. The semi-automatic selenium sand melon transplanter has high automation degree and can reduce the transplanting cost of selenium sand melons.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a semi-automatic selenium sand melon transplanting machine. Background technique [0002] Most of the existing selenium sand melon transplanting machines are drawn by agricultural tractors, and cooperate with two staff members to implement the transplanting work. One staff member performs the operation of throwing seedlings, and the other performs the operation of gathering soil. A mound of soil is formed around the seedlings to prevent lodging and preserve moisture; this kind of selenium sand melon transplanting machine needs to be equipped with two workers, which increases the labor cost; when performing soil gathering operations, human control is required, and its degree of automation is low , as improper operation can make melon seedlings be buried, its operation difficulty is big, can not satisfy market demand better.
