Description

Technical Field

[0001] This invention relates to a mulch film laying and soil covering machine for seedlings after planting, and in particular to a special machine for laying mulch film for perennial trees. Background Technology

[0002] With the development of water-saving agriculture, the application of water-saving technologies is constantly expanding and penetrating into forestry, especially in the planting of economic trees in arid regions, where its application is receiving increasing attention. Examples include the application of mulch film planting technology in the cultivation of goji berries, jujubes, and mulberry trees.

[0003] However, current machinery for mulching operations is mainly designed for general field operations. Since tree planting is perennial, while current mulching technology requires laying once a season or once a year, due to the special nature of trees, machinery for laying mulch for trees is very rare, resulting in a gap in the availability of mulch laying machinery for tree planting.

[0004] CN211322303U, CN214508420U, and CN205667181U all disclose a mulch film laying machine for garden planting. However, the structure of the disclosed machine is difficult to adapt to the characteristics of forest planting, especially the perennial characteristics and complex branches of trees such as wolfberry and jujube. For example, when wolfberry, jujube and other trees have grown for many years and have large canopies and horizontal branches, the above-mentioned mulch film laying machine is difficult to adapt.

[0005] Therefore, a special mulch film laying machine for forest planting, especially one adapted to the perennial characteristics and complex branches of trees, has emerged. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a special mulch film laying machine for forest planting, especially a mulch film laying and soil covering machine adapted to the perennial characteristics and branch complexity of economic forest trees such as wolfberry, jujube and mulberry after seedling planting.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a main frame (11) and a traction or suspension frame (12), characterized in that: a first side frame (21) is provided on the side of the main frame (11), the outer end of the first side frame (21) is open and suspended, and a soil scraper (24), a film roller, a film spreading roller (25) and a soil covering mechanism are arranged sequentially from front to back on the first side frame (21), the soil covering mechanism includes a soil covering basket (26), a soil cutting disc (27) is provided on the side of the soil covering basket (26) near the main frame (11), and the soil scraper (24), the film roller, the film spreading roller (25) and the soil covering mechanism are suspended on the first side frame (21).

[0008] Furthermore, a second side frame (22) is provided between the first side frame (21) and the scraper (24), the film roll frame, the film spreading roll (25) and the soil covering mechanism, and the second side frame (22) is movably connected to the first side frame (21).

[0009] The movable connection between the second side frame (22) and the first side frame (21) is either a bolted connection or a telescopic frame connection. Preferably, the telescopic frame connection is used: the second side frame (22) and the first side frame (21) are a telescopic mechanism consisting of a sliding rod and a sliding sleeve, and a first displacement drive mechanism (29) is provided between the second side frame (22) and the main frame (11). The first displacement drive mechanism (29) is either a hydraulic or an electric telescopic drive mechanism.

[0010] Furthermore, it is preferable to provide a lifting frame (28) between the first side frame (21) and the main frame (11). The lifting frame (28) is a displacement mechanism consisting of a sliding rod and a sliding sleeve, including a second displacement drive mechanism (30) and a sliding rod or sliding groove provided on the main frame (11). The first side frame (21) is provided with a corresponding sliding groove or sliding rod. The second displacement drive mechanism (30) is provided between the first side frame (21) and the main frame (11), or between the sliding rod or sliding groove connected to the main frame (11). The second displacement drive mechanism (30) is one of a hydraulic or electric telescopic drive mechanism.

[0011] Furthermore, the first side frame (21) is preferably provided with a dividing guard plate (32), which includes at least an inclined plate body that is lower in the front and higher in the back, located at the front of the first side frame (21).

[0012] Furthermore, the aforementioned main frame (11) is provided with a travel depth limiting wheel (13), and the travel depth limiting wheel (13) is connected to the main frame (11) through a swing frame. The upper end of the swing frame is hinged to the main frame (11). A travel depth limiting wheel lifting drive mechanism is provided between the main frame (11) and the swing frame. The travel depth limiting wheel lifting drive mechanism is one of a hydraulic or electric telescopic drive mechanism.

[0013] Furthermore, a ground wheel (33) can be installed on the second side frame (22). The ground wheel (33) is either a roller or a wheel. The ground wheel (33) can ensure the distance between the mulch film laying surface and the ground, and prevent excessive pressure from damaging the mulch film.

[0014] Compared with existing technologies, this invention is applicable to the laying of mulch film in forest planting, especially for the perennial characteristics and complex branching of economic forest trees such as wolfberry, jujube, and mulberry. It is suitable for laying mulch film and covering soil on the rows after planting seedlings, with high efficiency and good effect. Attached Figure Description
