Continuous film punching device for rapeseed perforating film laying hole seeder

Abstract

The invention discloses a continuous film punching device used for an oilseed rape punching film-spreading hill-drop planter. The continuous film punching device comprises a fixed frame, a rotary drumdevice, a main shaft and a plurality of punching units, wherein the rotary drum device is mounted on two upper side beams of the fixed frame; the main shaft is mounted on the upper surfaces of two lower side beams of the fixed frame; the punching units are sleeved on the main shaft and are distributed in the axial direction of the main shaft; each of the punching units comprises a punching rollerand a plurality of punching cone nails; a plurality of arc-shaped grooves are uniformly formed in each of the punching rollers along the outer periphery of the punching roller; the outer periphery ofeach of the punching rollers, located between every two adjacent arc-shaped grooves, forms an arc-shaped bulge; one punching cone nail is mounted on each of the arc-shaped bulges. The continuous filmpunching device used for the oilseed rape punching film-spreading hill-drop planter provided by the invention is high in punching efficiency and good and uniform in punching quality; compared with amanual punching manner, the continuous film punching device is time-saving, labor-saving, high in efficiency and stable in punching distance.

Description

technical field [0001] The invention belongs to the technical field of rapeseed perforating and film-laying hole seeder equipment, and in particular relates to a continuous-membrane punching device for rapeseed perforating and film-laying hole seeders. Background technique [0002] Rapeseed, as the main oil crop in my country, is divided into winter rapeseed and spring rapeseed planting areas. The planting area of ​​spring rapeseed accounts for about 10% of the total area of ​​rapeseed in the country, and is mainly distributed in high-altitude and high-latitude areas. In these areas, the temperature in spring is low, the wind is full of sand, the wind speed is relatively high, and there is little rain. Rapeseed film can effectively preserve moisture, increase ground temperature, and inhibit wind and sand invasion, but too high temperature will cause seedling burn, so it is necessary to perforate the film. The agronomic process of the existing film-laying machinery is mostly...

AI Technical Summary

Problems solved by technology

Rapeseed film can effectively preserve moisture, increase ground temperature, and inhibit wind and sand invasion, but too high temperature will cause seedling burn, so it is necessary to drill holes on the film

The agronomic process of the existing film-laying machinery is mostly sowing first and then filming. At the same time, it is necessary to manually cut the film and release the seedlings, which is time-consuming and laborious; although the commonly used duckbill hole seeder can realize the combination of punching technology and seeding technology, its structure is huge. It is easy to tear the agricultural film, which has the disadvantages of film hole adhesion and soil film adhesion, and is not suitable for small-sized rapeseed crops

The punching device is the key device for the film-laying operation of the rapeseed film-laying hole seeder. The punching of the existing agricultural film requires not only uniform punching, but also adjustable hole spacing and row spacing. The existing rapeseed film-laying seeder punching technology immature
