Dual-profiling sowing and mulching frame

Abstract

The invention discloses a dual-profiling sowing and mulching frame. The dual-profiling sowing and mulching frame comprises a suspension frame, a sowing and mulching frame, and a mulch earthing rollerbracket. One end of the suspension frame is connected with a tractor while the other end is connected with the sowing and mulching frame through first connecting rods arranged in pairs, and the suspension frame, the first connecting rods, and the sowing and mulching frame constitute a first four-rod linkage profiling mechanism. The sowing and mulching frame is connected with a suppression mechanism through a pair of second connecting rods, and the sowing and mulching frame, the second connecting rods, and the suppression mechanism constitute a second four-rod linkage profiling mechanism. The suppression mechanism comprises a profiling wheel, a seed arranging device and a sowing opener. One end of the mulch earthing roller bracket is connected with the sowing and mulching frame while the other end is connected with a roller. The sowing and mulching frame is provided with a mulch bracket and a film spreading pull rod connecting base, and a film dual-profiling sowing and mulching frame can simultaneously perform profiling sowing and mulching operations, which not only improves the consistency of sowing depth, but also achieves flat mulch.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a double profiling sowing film-covering frame. Background technique [0002] Seeding is the operation of sowing the sowing material into the soil layer at a certain depth in a certain amount and in a timely manner. Proper sowing directly affects the growth and yield of crops. In order to maintain the temperature and humidity of the land and protect the crop seedlings from the influence of diseases and insect pests, many crops often need to be covered with plastic film after sowing. [0003] Taking cotton as an example, cotton sowing has high requirements on the consistency of sowing depth, and the agronomic requirements are 1-2.5cm. Too deep or too shallow will affect the cotton seedling emergence rate. In severe cases, the cotton seedling emergence rate is very low and needs to be re-sown. Not only missed the best time for cotton sowing, but also wasted manpowe...

AI Technical Summary

Problems solved by technology

If it is too deep or too shallow, it will affect the emergence rate of cotton. In severe cases, the emergence rate of cotton is very low, and it needs to be re-sowed

Not only missed the best time for cotton sowing, but also wasted manpower and material resources

Cotton needs to be covered with film after sowing. If the film cannot always be close to the ground, the film will be uneven, which will affect the quality of the film and the utilization rate of the film.
