Description

A Wide Ridge Double Row Sweet Potato Horizontal Planter

technical field

The utility model belongs to the technical field of agricultural machinery, in particular to a wide-ridge double-row sweet potato horizontal planter.

Background technique

Sweet potato, also known as sweet potato, sweet potato, sweet potato, sweet potato, is resistant to barrenness, drought, strong adaptability, and high yield. The cultivated area and yield of sweet potato in my country ranks fourth after rice, wheat, and corn. It ranks fourth in my country's agricultural planting structure and play an important role in the production of food crops.

However, the transplanting method of sweet potato seedlings in production has an important impact on the yield of sweet potato. Direct planting, oblique planting and flat planting are three commonly used transplanting methods in agronomy. Among them, the direct planting method is to plant the seedlings vertically in the soil, and the number of sweet potato tubers after planting is small; the oblique planting method is to plant the seedlings obliquely in the soil, and the size of the sweet potato tubers after planting is uneven; the flat planting method is The seedlings are placed horizontally in the soil, and the sweet potatoes after planting are more and uniform in size, and this method is often used in large-scale high-yield fields. The horizontal planting method generally requires sweet potato seedlings _to be about 20-30cm long, and the seedlings are buried in the soil and each node is distributed in a shallow soil layer with a depth of about 5cm below the soil surface. In the process of horizontal planting on the ridge, when the seedlings are required to be planted parallel to the furrow, the section of the seedling head with leaves should be bent upwards to grow out of the ground, and the overall shape of the seedlings is ∟; One section of the seedling head with leaves should be exposed in the furrow, without bending the seedlings, the seedlings can be laid flat on the furrow with a depth of about 5 cm in a shallow ditch and covered with soil, and the rice seedlings can be planted on both sides of the soil furrow respectively. Whether the seedlings are planted parallel to the direction of the furrow or the seedlings are planted perpendicular to the direction of the furrow, manual work requires a large amount of labor, low efficiency, and high cost. The busy season of farming often delays the farming time. And existing transplanting machine is to directly plant seedlings mostly, lacks practical sweet potato level planting operating tool. Aiming at this current situation, the utility model provides a wide-ridge double-row sweet potato horizontal planting machine, which can continuously complete the operations of picking seedlings, sending seedlings, ditching, laying seedlings and covering soil when straddling the soil ridges. The seedlings are planted on both sides of the soil ridge perpendicular to the direction of the ridge, and the section of the seedling head with leaves is exposed in the ridge, so as to realize the high-efficiency operation of horizontal planting of sweet potatoes in double rows on a wide ridge.

when each of the transplanted When the mechanism rotates one circle counterclockwise with the ditching wheel, the planetary shaft fixedly mounted on the ditching wheel rotates counterclockwise with the ditching wheel, and the planets on the planetary shaft The wheel and the cam also rotate counterclockwise with the ditching wheel, and the planetary wheel of the transplanting mechanism installed on the right side of the ditching wheel is always in the process of rotating counterclockwise with the ditching wheel Engaging with the sun gear on the right side, the planetary gear of the transplanting mechanism installed on the left side of the ditching wheel is always in contact with the sun gear on the left side during the counterclockwise rotation of the ditching wheel. gear meshes, driving the cam around the planetary The shaft rotates clockwise, and the clockwise rotation of the cam drives the L-shaped closer to alternate between the open state and the closed state. 3. wide ridge double row sweet potato flat planter as claimed in claim 1, is characterized in that, described transmission device is made of right belt, left belt, motor right pulley, motor left pulley, conveyor belt pulley, transplanting mechanism The belt pulley is composed of: the right pulley of the motor and the left pulley of the motor are respectively installed on the rotating shafts at both ends of the motor, the belt pulley is installed at the left end of the transmission shaft of the conveying mechanism, and the transplanting mechanism The pulley is installed at the power shaft of the transplanting mechanism, the right pulley of the motor and the belt pulley of the conveyor belt form a belt drive with the right belt, the left pulley of the motor and the belt of the transplanting mechanism The wheel and the left belt constitute a belt drive, and when the motor is working, the power is transmitted to the transplanting mechanism and the conveying mechanism respectively through the transmission device. 4. wide ridge double row sweet potato horizontal planting machine as claimed in claim 1, is characterized in that, described running device is made of front wheel and rear wheel; Described front wheel is connected in the place ahead of described frame by rotating shaft, so Described rear wheel is installed in the rear of described frame by rotating shaft, and described traveling device provides forward traveling speed when this machine works. 5. wide ridge double-row sweet potato flat planter as claimed in claim 1, is characterized in that, described conveying mechanism further comprises: conveyer belt, conveying shaft; Described conveying shaft is installed on the described frame, and transmits power to The conveyor belt, sweet potato seedlings are placed on the conveyor belt, when the conveyor belt rotates, the sweet potato seedlings move with the conveyor belt and break away from the left end of the conveyor belt and fall. 6. The wide-ridge double-row sweet potato horizontal planting machine according to claim 2, wherein the cover plate is fixed on the frame, and when the machine is working during the traveling process, the opener digs out The soil is thrown behind the pit by the ditch opener, and the cover plate scrapes and fills the soil excavated in the ditching operation into the pit during the continuous travel of the work tool to complete the soil covering operation.
