DETAILED DESCRIPTION

[0032] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Embodiments of the present utility model: Figure 1-Figure 7 As shown, the utility model proposes a ground film breaking device, comprising a frame 1, a film breaking blade 2, a first driving mechanism and a second driving mechanism;

[0034] The first driving mechanism is installed on the frame 1, and the first driving mechanism is used to drive the second driving mechanism to move horizontally to adjust the distance between the film breaking blades 2 connected to the second driving mechanism; by setting the first driving mechanism, the distance between the film breaking blades 2 can be conveniently adjusted, and can be changed in real time with different film types, land environment and other factors to meet different film breaking requirements.

[0035] The second driving mechanism is used to drive the film-breaking blade 2 to float up and down. The second driving mechanism can be set to be the same as the number of the film-breaking blades 2, and control the up and down movement of the film-breaking blades 2 respectively, or one second driving mechanism can be used to simultaneously control the up and down movement of multiple film-breaking blades 2. The up and down floating of the film-breaking blade 2 can bring the ground film out of the soil while breaking the film, which is convenient for subsequent collection and processing.

[0036] As an implementation mode, the first driving mechanism includes a screw rod 3, a first driving motor 4, a nut, a connecting arm 5, a scissor structure 6 and a connecting block 7;

[0037] The screw 3 is rotatably installed on the frame 1, and one end of the screw 3 is transmission-connected to the first drive motor 4. As an implementation method, one end of the screw 3 is transmission-connected to the first drive motor 4 through a coupling, and the housing of the first drive motor 4 is fixedly installed on the frame 1 by bolts; the nut is threadably matched with the screw 3, and the nut is connected to the scissor-type structure 6 through a connecting arm 5; there are multiple connecting blocks 7, and the multiple connecting blocks 7 are all connected to the scissor-type structure 6; the connecting blocks 7 correspond one-to-one to the film-breaking blades 2, and the film-breaking blades 2 correspond one-to-one to the second driving mechanism, and the film-breaking blades 2 are slidingly connected to the connecting blocks 7 through the second driving mechanism; a connecting block 7 located in the middle position is fixedly connected to the frame 1, and the other connecting blocks 7 are slidably installed on the frame 1. In this way, when the screw 3 rotates, the nut moves along the screw 3, and at the same time drives the connecting arm 5 to move. The movement of the connecting arm 5 drives the scissors-type structure 6 to telescope. The scissors-type structure 6 drives the connecting block 7 that slides with the frame 1 to move closer to or away from the connecting block 7 that is fixedly matched with the frame 1. Because the film-breaking blades 2 are connected to the connecting block 7 through the second driving mechanism, the distance between the film-breaking blades 2 can change with the change of the distance between the connecting blocks 7, thereby realizing the adjustment of the distance between the film-breaking blades 2.

[0038] As an implementation method, the scissors structure 6 is formed by a plurality of hinged scissors rods; the scissors rods include a first rod 8 and a second rod 9, the middle parts of the first rod 8 and the second rod 9 are rotatably connected by a first pin 10, and the lower end of the first pin 10 is fixedly connected to the connecting block 7, so that when the scissors structure 6 is extended or retracted, it can drive the connecting block 7 to move; the connecting arm 5 is fixedly connected to the first pin 10 on the connecting block 7 that can slide along the frame 1, so that when the connecting arm 5 moves along the screw rod 3, it can drive the connecting block 7 connected thereto to slide, thereby driving the entire scissors structure 6 to extend or retract.

[0039] See also Figure 4 , Figure 7The second driving mechanism includes a first rack plate 14, a sector gear 15, a housing 16 and a second driving motor 17; there are two first rack plates 14, the two first rack plates 14 are fixedly mounted in parallel in the housing 16, and the teeth of the two first rack plates 14 are arranged opposite to each other; the first rack plate 14 and the frame 1 are perpendicular to each other, and the upper end of the membrane breaking blade 2 is detachably mounted in the housing 16; the sector gear 15 is located between the two first rack plates 14, and the sector gear 15 can be respectively engaged with the two first rack plates 14. When the sector gear 15 is engaged with one of the first rack plates 14, it can drive the housing 16 to move upward, and when the sector gear 15 is engaged with the other first rack plate 14, the housing 16 can be driven to move upward. When a rack plate 14 is meshed, it can drive the housing 16 to move downward. Such a design can realize the up and down floating of the film-breaking blade 2. The frequency of up and down floating can be achieved by controlling the rotation speed of the fan gear 15. Further, the fan gear 15 is fixedly mounted on one end of the first rotating shaft, and the other end of the first rotating shaft is fixedly connected to the output shaft of the second drive motor 17 through a coupling. The housing of the second drive motor 17 is fixedly mounted on the connecting block 7 by bolts. In this way, the rotation of the second drive motor 17 can drive the first rotating shaft to rotate, and the first rotating shaft drives the fan gear 15 to rotate. The rotation of the fan gear 15 drives the housing 16 to reciprocate up and down. The film-breaking blade 2 is designed to be detachably connected to the housing 16. Different types of cutter heads can be replaced according to different usage environments to better perform film-breaking operations, and it is also convenient to replace a single film-breaking blade 2 when it is damaged.

In order to make the connecting arm 5 move more smoothly without rotating, it can be adopted that: the frame 1 is provided with a first limiting groove 101 along the length direction, and a first limiting rod 12 is fixedly installed below the connecting arm 5, and the lower end of the first limiting rod 12 is located in the first limiting groove 101 and slides with the first limiting groove 101.

[0041] As an implementation method, the frame 1 is fixedly mounted with a mounting plate 13 along the length direction, and the connecting block 7 is slidably sleeved on the mounting plate 13. Of course, a sliding groove can also be provided on the frame 1, and the connecting block 7 is slidably mounted in the sliding groove.

[0042] The connecting block 7 is provided with a second limiting groove 71, which is provided in a direction perpendicular to the frame 1, and the housing 16 is provided with a slide bar that slidably cooperates with the second limiting groove 71; the housing 16 is provided with a third limiting groove 161; the third limiting groove 161 is provided along the length direction of the slide bar; the connecting block 7 is provided with a second limiting rod 19, one end of which passes through the third limiting groove 161 and slidably cooperates with the third limiting groove 161.
