Sunflower deseeding machine

Abstract

The invention discloses a sunflower deseeding machine, and belongs to the field of agricultural machines. The sunflower deseeding machine is composed of a shell, a vibration screening device, a rotary deseeding device and a transmission feeding device. The sunflower deseeding machine is characterized in that the vibration screening device is installed at the bottom inside the shell, the rotary deseeding device is installed at the upper end of the shell and located above the vibration screening device, and the transmission feeding device is installed on the right side face of the shell. An asynchronous motor is adopted for providing power, transmission is achieved through a synchronous belt, and the machining speed and the power transfer efficiency are greatly improved; transverse protrusions are evenly arranged on the surface of a belt, friction between the belt and a sunflower head is increased, and the sunflower head can be better fed to a rotary tray. A belt wheel is driven by a maltese mechanism to achieve interval feeding of the belt, interval feeding is matched with eccentric movement of the rotary tray to achieve complete feeding, and sunflower deseeding is achieved through the rotary deseeding device.

Description

technical field [0001] The invention relates to a sunflower seed removal machine, in particular to a sunflower seed removal machine which adopts a belt drive and peels off sunflower seeds through mutual rotation and friction of upper and lower disks, and belongs to the field of agricultural machinery. Background technique [0002] After the sunflower is mature, the sunflower seeds need to be separated from the sunflower tray. When the sunflower is mature, the sunflower tray is usually dried, and then it is manually crushed and beaten to remove the sunflower seeds from the sunflower tray and processed by wind. Blow off the debris of the sunflower plate after the sunflower to separate the sunflower seeds. This method not only wastes a lot of labor, but also has low efficiency. At present, there are some drum-type general-purpose threshers, but for sunflower threshing, the damage to the sunflower seeds is relatively large. Reasons such as large size and imperfect separation can...

[0002] After the sunflower is mature, the sunflower seeds need to be separated from the sunflower tray. When the sunflower is mature, the sunflower tray is usually dried, and then it is manually crushed and beaten to remove the sunflower seeds from the sunflower tray and processed by wind. Blow off the debris of the sunflower plate after the sunflower to separate the sunflower seeds. This method not only wastes a lot of labor, but also has low efficiency. At present, there are some drum-type general-purpose threshers, but for sunflower threshing, the damage to the sunflower seeds is relatively large. Large and imperfect separation and other reasons can not be widely promoted, so there is an urgent need for a device specifically for sunflower threshing
