The 2CMX-2B potato planting machine is a large-scale mechanized potato planting machine developed in collaboration with Shandong Xicheng Agricultural Machinery Technology Co., Ltd., Shandong University of Technology, and Shandong Agricultural Machinery Science Research Institute. It has advanced characteristics such as high complexity, high precision, and high adaptability, and can complete a series of operations such as trenching, planting, ridging, fertilization, and spraying in one go. It adopts advanced vibration and tension seeding unit technology, with low seed leakage rate and heavy seeding rate, high seeding accuracy, and precise planting unit and precise control of planting depth technology to improve the adaptability of the product. All performance indicators and quality indicators have been tested by relevant departments. The trial production of the 2CMX-2B potato planting machine meets the relevant quality standards, which brings great convenience to potato planting production, reduces labor intensity, improves labor productivity, reduces production costs, and significantly improves its comprehensive benefits.

Marking device: By adjusting the length of the marking device to be at the center of the track, it is beneficial for the driver to sow in the next row.
Seed planter: The outer cover of the seed planter is a chain with long bowls and spoons arranged in a staggered and equidistant manner. The bowl and spoon base is equipped with replaceable potato bowls, and the back of the bowl and spoon is equipped with a flange. Realize automatic control of sowing quantity and uniform sowing, effectively reducing missed and replanted rates.
Material box: used for storing potato seeds, with a capacity of 2 cubic meters.
Ground wheel: The ground wheel is an active transmission mechanism that adjusts the plant spacing according to different speed ratios.
Soil tray: The soil tray is an arc-shaped disc that is connected to the angle adjustment frame through shaft sleeves, bearings, bolts, and can rotate around it. Used for ridge formation and controlling the shape of potato ridges.
Chain transmission device: used to transmit the east direction of the ground wheel to the potato discharge tube.
Rack: The rack is the main part of the implement, used to fix the potato box, seeder, etc., and also used for connecting the implement with the tractor.


1. Precision Potato Planting Technology:The existing potato planting machines adopt a relatively simple chain bowl planting method. Without the help of manual labor, the re planting rate is higher than 25%, the missed planting rate is higher than 15%, and the young bud damage rate is higher than 2%. The operating efficiency is low, and it is not suitable for large-scale mechanized planting of potatoes. The sowing unit of this potato planting machine adopts a "bowl spoon" type seeding device with independent intellectual property rights, as well as vibration, shaking, and chain tensioning mechanisms, achieving precise sowing without the need for manual labor. The leakage index is reduced from below 15% to below 10%, the reseeding index is reduced from below 25% to below 20%, the damage rate of potato sprouts is reduced from below 2% to below 1.5%, and the qualified index of potato spacing is increased from not less than 67% to not less than 85%.

2. Precise depth control technology for potatoes:The depth of the existing potato planting machine is controlled by a fixed trencher and three-point suspension of the tractor, and its planting depth is greatly affected by the terrain. The potato planting machine adopts a single depth limiting and copying mechanism for planting depth control, which solves the uneven sowing depth caused by factors such as region and soil, and improves the stability of sowing depth.


3. Potato ridge control technology:The existing potato planting machines mostly use plow type or disc type soil support plates, which are difficult to adjust in angle and have irregular ridges. The potato planting machine has broken through the inherent mode and developed a disc type ridge support device, which has expanded its application range. The applicable row spacing has been increased from 600-700mm to 700-900mm, and the adaptable plant spacing has been increased from 200-350mm to 170-440mm. The ridge shape control is more diverse and can meet different agronomic requirements.

4. Design potato bowls in three different sizes that can be replaced,Arrange and install in a staggered and equidistant manner on the potato seed belt of the seed planter, and the back of the bowl and spoon is equipped with a flange. The range of adaptation to potato cultivation has been expanded from the traditional 30-50 grams to 15-80 grams.


5. The spraying system uses polytetrafluoroethylene nozzles with higher atomization degree,Not only is its angle adjustable, but it has also been changed from traditional spraying after planting potatoes to front and back spraying, making the coverage more tight.
