Description

Technical Field

[0001] The utility model relates to the field of tillage equipment, in particular to a film covering device and a tillage machine. Background Art

[0002] Tillers are agricultural machinery widely used in agricultural production. They can travel on the road and cultivate the soil or fields. They are mainly used for soil plowing, land leveling, soil preparation before sowing, and other tasks.

[0003] A film spreader is a mechanical equipment commonly used in agricultural planting. Its main function is to cover the crops with plastic film after sowing or transplanting to maintain soil moisture, increase ground temperature, inhibit weed growth and promote early maturity and increased yield of crops. After connecting the film spreader to the tillage machine, it relies on the drag of the tillage machine to carry out ridge formation, film laying, compaction and soil covering. However, after the tillage is completed, since the film spreader needs to sink into the soil during tillage, when switching to the walking state to move to the next tillage area, the film spreader needs to be disassembled first, and then installed after arriving at the next tillage area. The operation is more troublesome. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a film covering device that is convenient for adjusting the height of the film spreader to adapt to different states of the tiller.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A film covering device is used for a tillage machine, including a connecting mechanism and a film covering mechanism for covering the film. The connecting mechanism includes a connecting frame, a rotating frame and a limiting part. The connecting frame is connected to the rear end of the tillage machine. The rotating frame is fixedly connected to the film covering mechanism and can rotate around the connecting frame on a vertical plane. When the rotating frame rotates to a specified angle, the limiting part can limit the rotating frame.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The film covering mechanism can be connected to the tillage machine through a connecting mechanism. In the tillage mode, the dragging film covering mechanism is in a horizontal state and can be used for film covering. In the walking mode, by setting a rotating frame and a limiting part, when the rotating frame is rotated to a horizontal position or leaves the ground, it can be limited by the limiting part to keep its position fixed, thereby meeting the needs of both states.

[0009] As a preferred embodiment of the present invention, the connecting frame includes two first plates arranged vertically at intervals, each of the two first plates is provided with a first rotation hole, a second rotation hole is horizontally provided on the rotating frame, and a rotating rod is passed through the two first rotation holes and the second rotation holes, and the two side walls of the rotating frame are respectively in contact with the inner walls of the corresponding first plates.

[0010] Beneficial effect: By setting the rotating rod, the movable direction of the rotating frame is limited, and the two sides of the rotating frame are further limited by the two first plates, so the lateral support effect is better, making it more stable when rotating.

[0011] As a preferred embodiment of the present invention, the connecting frame further includes a second plate body, and two sides of the second plate body are fixedly connected to the bottom surfaces of the two first plate bodies respectively.

[0012] Beneficial effect: By setting the second plate, during the process of adjusting the height of the rotating frame, the rotating frame lacks a limit and will deflect downward due to gravity, thereby preventing the rotating frame from deflecting downward too much, which would make it too difficult to bend the rotating frame upward.

[0013] As a preferred embodiment of the present invention, the connecting frame further comprises a third plate body, wherein upper and lower ends of the third plate body are respectively bent to form straight portions, and a plurality of mounting holes are vertically provided on the straight portions.

[0014] Beneficial effect: By setting up a third plate with a straight portion, a transverse through groove is formed, which is installed with the tiller and then fixed by screws passing through the mounting holes. The straight portion below supports the connection. Compared with directly supporting gravity through screws, the force is more uniform.

[0015] As a preferred embodiment of the present invention, the connecting frame is detachably connected to the rear end of the tiller by bolts.

[0016] Beneficial effect: detachable connection through bolts, easy to disassemble and assemble.

[0017] As a preferred embodiment of the present invention, the limiting portion includes a first limiting rod, a second limiting rod and two fourth plates, the two fourth plates are arranged at intervals, the first limiting rod and the second limiting rod are arranged at intervals between the two fourth plates, the first limiting rod rests on the upper end surface of the rotating frame, and the second limiting rod rests on the lower end surface of the rotating frame;

[0018] The connecting frame is provided with a first positioning slot and a second positioning slot. When the first limiting rod is located in the first positioning slot, the laminating mechanism is in a horizontal state. When the first limiting rod is located in the second positioning slot, the laminating mechanism is off the ground.

[0019] Beneficial effect: By setting the first positioning groove and the second positioning groove, the limiting part can switch the coating mechanism to a horizontal state or off the ground. The rotating frame tends to rotate downward due to gravity, and the second limiting rod supports it. Moreover, since the second limiting rod is connected to the first limiting rod through the fourth plate, and the first limiting rod is limited by the first positioning groove or the second positioning groove, the position can be fixed.

[0020] As a preferred embodiment of the present invention, a first tension spring is provided between the lower portion of the fourth plate and the rotating frame.

[0021] Beneficial effect: By setting the first tension spring, when the first limit rod is in the second positioning groove, the first tension spring is stretched. When it is necessary to switch to the first positioning groove, the first limit rod is manually pulled out and disengaged from the second positioning groove. Due to the recovery of the deformation of the first tension spring, the first limit rod is pulled toward the first positioning groove to achieve reset.

[0022] As a preferred embodiment of the present invention, the film covering mechanism includes a furrowing plate, a roller mounting part, a compacting wheel and a covering plate arranged in sequence from front to back, and the number of the furrowing plate, the roller mounting part, the compacting wheel and the covering plate are two. The two furrowing plates push the bottom soil away from the outside of the sowing area, a roller with a film can be installed between the two roller mounting parts, the two compacting wheels compact the film inward, and the two covering plates push the outer soil back to both sides of the film.

[0023] Beneficial effects: Sowing is often carried out side by side, and the covering mechanism is dragged along each row of sowing areas. The furrowing plate pushes the bottom soil away from the outside of the sowing area to form a ditch, which plays the role of ridge formation. The roller with the film contacts the sowing area and rotates continuously during the dragging process to lay the film. The compacting wheel compacts the film on both sides of the sowing area, and finally guides the soil to both sides of the film, compacting the film to achieve automatic covering.

[0024] As a preferred embodiment of the present invention, the coating mechanism also includes a rectangular frame and two flexible rods, the upper parts of the two flexible rods are rotatably installed on both sides of the rectangular frame, the two compacting wheels are respectively installed on the lower parts of the corresponding flexible rods, and a second tension spring is arranged between the two sides of the rectangular frame and the middle parts of the corresponding flexible rods.

[0025] Beneficial effect: By setting the flexible rod and the second tension spring, when the towing speed is fast, the flexible rod can be deflected backward to provide buffering, thereby preventing the compacting wheel from directly dragging the film forward due to friction, which may cause wrinkles in the laid film.

[0026] The second purpose of the present invention is to provide a tillage machine that adopts the above-mentioned film covering device to facilitate switching between tillage mode and walking mode. BRIEF DESCRIPTION OF THE DRAWINGS
