Elevating tobacco seed threshing machine

Abstract

The invention provides an elevating tobacco seed threshing machine comprising arc-shaped blades. The arc-shaped blades are rotationally connected with a driven wheel via a rotating roller; the driven wheel is in a transmission connection with a driving wheel via a belt; a screen mesh is arranged between the arc-shaped blades and an air chamber; the left end of the air chamber is provided with an air blower; a rough screening plate is placed between the air chamber and a seed receiving plate; the bottom of the seed receiving plate is connected with a cam via a rocking rod; a connection rod is engaged with a rotating shaft via a gear; the connection rod is rotationally connected with a supporting rod via a bearing; the driving wheel is rotationally connected with a motor via the rotating shaft; a plurality of connection blocks are mounted on the bottom of a machine body; a first screw hole is formed in the middle of each connection block; a screw rod is installed in the first screw hole; the lower end of the screw rod is provided with a cushion block; and an antiskid pad is mounted on the bottom of the cushion block. The length of the first screw rod extending out of the first screw hole can be adjusted via rotation, so overall height of a feeding port can be adjusted and the threshing machine can be adjusted to a proper height; and the elevating tobacco seed threshing machine can be suitable for various occasions and facilitate operator use.

Description

technical field [0001] The invention belongs to the technical field of tobacco machinery, and in particular relates to a lift-type tobacco seed thresher. Background technique [0002] The traditional tobacco threshing method is mainly threshing by human rubbing, flail and beating. This method has low productivity, labor and time-consuming, and increases labor intensity. Tobacco seeds are threshed by other seed threshers, and the process will be slow. It is obviously faster, but the threshed seeds will have a certain degree of seed coat damage, and the threshed seeds are mixed with large and small seeds, and contain more impurities, and need to be processed twice or three times before they can be stored. Very loaded down with trivial details, increases the dynamics of labor, can not satisfy people's demand. In some cases, it is necessary to move the threshing machine to a higher position for threshing, and the height of the operator is not certain. The existing threshing mac...

[0002] The traditional tobacco threshing method is mainly threshing by human rubbing, flail and beating. This method has low productivity, labor and time-consuming, and increases labor intensity. Tobacco seeds are threshed by other seed threshers, and the process will be slow. It is obviously faster, but the threshed seeds will have a certain degree of seed coat damage, and the threshed seeds are mixed with large and small seeds, and contain more impurities, and need to be processed twice or three times before they can be stored. It is very cumbersome, increases the intensity of labor, and cannot meet people's needs

In some cases, it is necessary to move the threshing machine to a higher position for threshing, and the height of the operator is also not certain. The existing threshing machine cannot adjust the height and needs to be heightened on site, which cannot adapt to different heights and heights. needs of operators, affecting work efficiency
