Mini type mulching film recovery machine of tobacco in seedling stage

Abstract

The invention relates to a mini type mulching film recovery machine of tobacco in seedling stage, which mainly comprises a seedling protective plate (1), a depth limiting land wheel (7), a break shovel (2), a stander (11), a large chain wheel (13), a small chain wheel (17), a gear wheel (18), a pinion (22), a film rolling roll (15), a universal joint (16), a position horizontal adjusting rod (20)of the film rolling roll and an angle vertical adjusting rod (25) of the film rolling roll. The gear wheel (18) and the pinion (22) are meshed to make the film rolling roll (15) and a driving wheel toreversely rotate to roll the film, so earth rolling is avoided; the inclined angle of the film rolling roll (15) can be adjusted by the universal joint (16), the angle vertical adjusting rod (25) ofthe film rolling roll and the position horizontal adjusting rod (20) of the film rolling roll according to the inclined angle of a tobacco ribbing surface; and the film rolling roll (15) is always well attached to the inclined plane of tobacco ribbing by the depth limiting land wheel (7) under the action of a depth limiting spring (8). The small tobacco seedling stage mulching recovery machine isused for recovering mulching films of seedling-stage tobacco planted in ridge culture, belongs to field tending machinery and is also suitable for recovering mulching films of cotton and other flat planting crops.

Description

(1) Technical field [0001] The invention relates to a tobacco machine used for recycling plastic film at the seedling stage of tobacco, belonging to field management machines. (2) Background technology [0002] Since the popularization of plastic film mulching cultivation technology, it has played an important role in tobacco production. However, due to neglect of plastic film recycling, a large amount of plastic film remains in the soil, destroys the soil structure, and causes serious white pollution to the tobacco production environment. Recycling plastic film has become an inevitable trend. The main reason for the white pollution of tobacco production is that there is no machinery suitable for the recovery of residual film in tobacco fields. Manual film collection is carried out, which has high labor intensity, low productivity and low recovery rate. A large number of experimental studies have shown that after tobacco harvesting, the mulch film has been broken and most ...

AI Technical Summary

Problems solved by technology

The main technical difficulties are that the depth of the tobacco planting furrow is large (depth 200-250mm), the slope angle of the furrow is large (the angle between the horizontal line is 25°-37°), and the existing film picking mechanism is horizontal axis rotation operation, which cannot be realized Copying film picking; when the tobacco plant grows 300-400mm in height, the tobacco leaves have been unfolded by 100-150mm, and the film must be collected by a small-diameter film roll. There is soil entanglement when the roll is wound, especially when the small-diameter film roll is wound, the soil entanglement is particularly serious; the tractor has a small ground clearance and cannot perform cross-row film winding operations
