Corn Thresher is composed of separate unicast groups, each group is driven by ground wheels, and can be used with tractors of different sizes to form 2-6 rows of rice transplanters with the characteristics of building blocks.
Rotating Cup Feeder
The feeder of the stevia transplanter consists of several feeders, and the diameter of the feeder cup corresponds to the size of the seedling bowl. There is a valve under each feeder. The opening and closing of the valve is controlled by a cam mechanism. When the feeding cup turns to the top of the seedling guide tube, it opens to let the seedlings fall, and then closes. When the feeding cup is closed, seedlings can be fed. Therefore, the manual feeding time is increased, and continuous feeding operation can be carried out. It can feed 60-70 plants per minute. This is the faster feeding frequency of the semi-automatic transplanter, because the frequency of manual feeding is limited. For the rotor feeder, the limit is 70 plants per minute, and the operator will feel nervous and misrepresented.
Grid Seedling Raising Device
After the seedlings fall from the pipe, they fall into the trench of the trencher through the ditch formed by the support rod. Under the support of the support rod, the seedlings will not tilt in any direction and are in an upright state. When the trencher moves forward, the soil flowing back from the tail of the trencher first covers the roots of the seedlings to form an overburden. When the machine moves forward, the support rod is also in an upright state, and the V-shaped pressing wheel pushes the soil on the ditch wall down to form a two-layer overburden and compact it. At this time, the seedling support rod moves upward relative to the seedling to continue to support the seedling to prevent the seedling from being crushed or buried by the soil during the covering and compaction process. As the machine moves forward, the seedling support rod will gradually move upward and away from the seedling to complete the task of supporting the seedling, and the seedling planting process ends. Due to the adoption of the net support device, the verticality of the seedlings and the stability of planting quality are greatly increased.
Seedling guide tube
The role of the seedling guide tube in China Rice Planting Machine is to transport the seedlings to the bottom of the ditch. Since the movement of the seedlings in the seedling guide tube is not compulsory, it is not easy to cause damage to the seedlings, which is different from the forced delivery method of the clamp type transplanter.
