Articulated multifunctional celery planting integrated machine

Abstract

The invention relates to an articulated multifunctional celery planting integrated machine, which belongs to the technical field of agricultural machinery. A compaction wheel, a rotary-tillage ridging device, a film mulching device, a land wheel, a perforating device and a seed discharge device are arranged on an articulation frame of the machine from front to rear, the perforating device comprises a liftable film-pressing plate driven by a lifting drive device, a sponge mat is attached to the lower surface of the film-pressing plate, perforated holes are distributed at certain interval on the film-pressing plate in a direction perpendicular to the forward direction of the articulation frame, a rotatable circular-tube perforating tool of which the lower end is provided with a cutting edge is inserted in each perforated hole, the upper end of the circular-tube perforating tool is coaxially connected with a chain wheel driven by a transmission chain, and the chain is in transmission connection with an output shaft of a gearbox fixedly connected on the film-pressing plate. According to the invention, regular circular holes can be cut on a film, so that the deformation of the film is completely avoided; and the perforated holes are completely consistent in depth.

Description

technical field [0001] The invention relates to a celery planting machine, in particular to a articulated multifunctional celery planting machine, which belongs to the technical field of agricultural machinery. Background technique [0002] Celery is the main vegetable in cold and cool regions. Its seeds are small and the emergence of seedlings is weak, so the seeding rate and planting density are large. The whole crop mulching, sowing, and harvesting in cultivation need mechanization. [0003] Intensive planting of celery usually requires a horizontal and vertical spacing of 15cm, sowing 20-25 seeds per hole, sowing depth of 2-3mm, covering the seeds with washed sand, and the thickness of the sand is 1-1.5cm. Mechanical operations need to achieve film holes , sowing and covering sand and a series of process actions. [0004] It can be seen from the search that the Chinese patent with the patent number ZL201420624230.0 discloses a self-propelled film-drilling, seeding, and ...

Problems solved by technology

[0005] However, in the actual promotion and application, the applicant found that the all-in-one machine still has the following bottleneck problems: not only is it difficult to control the depth of the hole punched by punching, but also the plastic film is easily torn and deformed during punching, and it is difficult to ensure that each hole is formed. Through the regular holes of the mulch film, thus affecting the flatness of the mulch film and the subsequent sowing quality
