Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and specifically relates to a ridging and mulching machine. Background Art

[0002] A ridging and mulching machine is an agricultural machinery device that combines the functions of ridging and laying plastic film, and is widely used in the process of crop planting. It can often be used in conjunction with a tractor, and the tractor provides power to realize a series of operations such as soil tillage, ridging, film laying, and soil pressing. The use of the ridging and mulching machine greatly improves the efficiency and quality of agricultural production, and at the same time reduces the labor intensity of farmers.

[0003] Common ridging and mulching machines usually consist of a rotary tillage and soil crushing part, a ridging and shaping part, and a film covering and soil pressing part. The rotary tillage and soil crushing part is responsible for tilling and crushing the soil to form ridge bodies. The ridging and shaping part controls the height and flatness of the ridge bodies through the adjustment of the drag plate and the pressure roller. The film covering and soil pressing part is responsible for laying the plastic film on the ridge bodies and compacting it through the pressure roller to ensure that the plastic film is closely attached to the soil and prevent the plastic film from being damaged by wind and sun.

[0004] However, in this method, since it is necessary to use a pressure roller to tightly press the plastic film after ridging, and the diameter of the pressure roller installed on the ridging and mulching machine is usually fixed. However, during actual operation, the depths of the furrows opened in different lands are different. The pressure roller with a fixed diameter cannot effectively compact the plastic film in deeper furrows, resulting in gaps between the plastic film and the soil, affecting the sealing performance and protection effect of the plastic film. On the contrary, for shallower furrows, it may cause the plastic film to be overstretched or even broken, which is also not conducive to the normal use of the plastic film. Therefore, it is necessary to frequently disassemble and install the pressure roller according to the situation for replacement during ridging and mulching, which is time-consuming and laborious during the entire use process and cannot meet the working requirements of the ridging and mulching machine. For this reason, a ridging and mulching machine is proposed. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a ridging and mulching machine to solve the technical problem that due to the fixed diameter of the pressure roller, the plastic film cannot be effectively compacted, resulting in the need to frequently disassemble and install the pressure roller for replacement according to the situation during ridging and mulching.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solutions: A ridging and mulching machine, comprising:

[0009] A cross beam, both the left and right sides of the front part of the cross beam are connected with vertical beams, a roller is installed at the front end inside the vertical beams, and ditch openers are installed at the front ends of the vertical beams;

[0010] The mounting plate is connected to the rear side of the bottom of the vertical beam. Transverse arms are connected to the front parts of the inner sides of the mounting plates. Crosses are installed at the inner ends of the transverse arms. Assembly rods are horizontally connected to the middle parts of the inner sides of the crosses.

[0011] The sleeve is sleeved on the outside of the assembly rod. Lower hinge plates are circumferentially connected to the outside of the sleeve. Transmission connecting rods are installed on the left and right sides of the outside of the lower hinge plates through bearings. Upper hinge plates are movably inserted into the outer sides of the transmission connecting rods through bearings.

[0012] Arc-shaped pressing blocks are installed at the outer ends of the upper hinge plates. Screws are screwed inside the assembly rods. Discs are coaxially installed at the outer ends of the screws. Ball bearings are sleeved on the outside of the screws, and end caps are sleeved on the outside of the ball bearings.

[0013] Preferably, chutes are opened on the left and right sides and the upper and lower sides inside the cross. Blocks are inserted into the inside of the chutes. The outer ends of the inner sides of the blocks are connected to the corresponding positions of the arc-shaped pressing blocks, improving the stability when the arc-shaped pressing blocks open and close.

[0014] Preferably, the numbers of the lower hinge plates, the transmission connecting rods, the upper hinge plates and the arc-shaped pressing blocks are all 3 - 6 groups. The corners at the upper and lower sides of the arc-shaped pressing blocks are all rounded, preventing the problem of scratching or tearing when the arc-shaped pressing blocks press the mulch film.

[0015] Preferably, hanging brackets are installed on the left and right sides of the top of the cross beam. A reinforcing beam is welded at the middle position of the top of the vertical beam. A connecting bracket is installed on the lower side inside the hanging bracket, and the bottom end of the connecting bracket is connected to the outside of the reinforcing beam, improving the overall strength of the cross beam and the vertical beam.

[0016] Preferably, a cross roller is installed at the position on the left side of the transverse arm inside the mounting plate. The insides of the cross beam, the vertical beam, the reinforcing beam and the arc-shaped pressing block are all hollow structures, reducing the overall weight of the machine body.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a ridging and mulching machine, which has the following beneficial effects:

[0019] The ridging and mulching machine drives the rotation of the screw by rotating the turntable, so that the left and right movement of the sleeve can be pushed by the end cover, enabling the synchronous opening and closing of the upper hinge plate and the arc-shaped pressing block to be driven by the transmission connecting rod. Furthermore, the diameter size with the assembly rod as the center between the arc-shaped pressing blocks can be quickly adjusted, allowing for rapid adjustment according to different ridge groove depths. This avoids the problems of gaps between the mulch film and the soil and excessive stretching and rupture of the mulch film caused by pressing the film with a fixed diameter. At the same time, it also avoids the problem of frequent disassembly and assembly of the pressure roller, improving the convenience and adaptability of the ridging and mulching machine during use.
