Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and specifically relates to a "feng"-shaped grass square planting device. Background Art

[0002] The grass square wind prevention and sand fixation technology is an important technology for controlling desertification in China. By pressing grass mats into sand manually or mechanically, the surface roughness of sandy land is improved. Most of the existing grass square laying devices currently adopt a unidirectional grass square laying mode, which leads to problems such as overlapping working paths and tire pressing on grass during laying. At the same time, traditional grass pressing lays grass squares by means of inserting grass with an inserting knife, which consumes a large amount of grass and is not conducive to the promotion of grass square sand control technology. Therefore, a "feng"-shaped grass square planting device is designed, which adopts a planting method to lay transverse and longitudinal grass squares during traveling, provides solutions for the grass pressing problem of the grass square laying device, reduces grass consumption and reduces resource waste.

One end of the hydraulic rod one (24) is connected to the inclined plate, and the other end is connected to the frame (11). The hydraulic rod one (24) extends... When the straw curtain is pushed out, the inclined plate is pressed down, and the inclination increases; when the hydraulic rod one (24) retracts, the inclined plate is lifted up, and the inclination decreases; the two guide plates (25) are fixed on the inclined plate (22), and the straw curtain is conveyed downward through the guide groove between the two guide plates (22). The trench opener (26) is installed at the bottom of the inclined plate (22) and connected to the inclined plate (22) through the guide rail. It can move along the direction of the inclined plate.

The guide wheel (36) is installed at the four corner positions on both sides of the turning table (35) through bearings. During the turning process of the turning table (35), it is always tangent to the baffle (310), so that the baffle (310) always maintains a certain distance from the turning table (35). The baffle (310) is connected to the grass feeding device frame (31) through the return spring (39). During the turning process of the turning table (35), the baffle (310) and the guide wheel (36) are in real-time contact through the return spring.

When the straw roll falls a certain length, the moving blade (312) moves towards the fixed blade (311), and the two blades combine to cut the straw mat. After the straw mat is cut, the turntable (38) drives the grooved wheel (37) and the turning table (35) to rotate 90° towards the baffle, so that the straw mat on the turning table (35) falls into the horizontal straw mat planting device through the gap formed between the turning table (35) and the baffle (310).

The fixed grass bucket (47) is fixed to the grass bucket support seat (46). The moving grass bucket (48) can move along the inner wall of the grass bucket support seat (46). The sliding rod (410) at the top of the moving grass bucket (48) extends into the cam groove on the outside of the active turntable (42). As the active turntable (42) rotates, the sliding rod (410) drives the moving grass bucket (48) to move up and down, realizing the opening and closing of the moving grass bucket (48) and the fixed grass bucket (47). The rotating wheel (45) is installed in the inner circle of the driven turntable (43). The three sets of rotating wheels are connected to the grass planting device frame (41).

After the transverse grass curtain discharging device (3) vertically places the transverse grass curtain into the rotating grass hopper of the transverse grass curtain planting device (4), the grass hopper is maintained in a vertical state to insert into the sand through the eccentric wheel structure formed by the driving turntable (42) and the driven turntable (43). When the grass hopper reaches the lowest point position, the grass hopper opens to leave the grass curtain in the sand, completing the planting operation of transverse grass curtains during the traveling of the chassis. The "feng"-shaped grass checkerboard planting device realizes "feng"-shaped grass checkerboard planting through one set of longitudinal grass curtain planting device (2) and two sets of transverse grass curtain planting device (4).

[0032] refer to Figure 9 , Figure 10: In the working process of the "Feng"-shaped grass square planting apparatus, the longitudinal grass curtains are conveyed downward through the guide slot formed by two guide plates (26) of the longitudinal grass curtain planting device (2), enter the sand ditch opened by the furrow opener (26), and then are filled and compacted by the rear sand-covering wheel (28) to complete the planting operation of the longitudinal grass curtains during the traveling of the chassis. After the transverse grass curtain placing device (3) vertically places the transverse grass curtains into the rotating grass hopper of the transverse grass curtain planting device (4), the eccentric wheel structure formed by the driving rotating disc (42) and the driven rotating disc (43) keeps the grass hopper in a vertical state and inserts it into the sand. When the grass hopper reaches the lowest point position, the grass hopper opens to leave the grass curtain in the sand, and the planting operation of the transverse grass curtain during the traveling of the chassis is completed. The "Feng"-shaped grass square planting apparatus realizes the "Feng"-shaped grass square planting through one set of longitudinal grass curtain planting devices (2) and two sets of transverse grass curtain planting devices (4).
