Description

Technical Field

[0001] The utility model relates to the field of ploughs, and more specifically to a saline-alkali land deep ploughing device. Background Art

[0002] In order to achieve better results in saline-alkali land restoration, it is generally necessary to deep plow the saline-alkali land first and then spray the restoration liquid on it so that the soil of the saline-alkali land can fully contact with the restoration liquid. Therefore, a deep plowing device is needed to deep plow the saline-alkali land.

[0003] The most important component in a deep tillage device is a plow. Currently, there is a plow on the market that is composed of an arc-shaped arm and an arc-shaped plow blade. Although it can be driven by a tractor to perform deep tillage, the plow blade is mostly fixedly installed on the arc-shaped arm. When the bottom of the plow blade hits a hard stone, the bottom of the plow blade is easily damaged due to the lack of a corresponding redundant mechanism, which affects its service life. In addition, there is a lack of a corresponding adjustment mechanism on the arc-shaped arm, which makes it inconvenient to adjust the angle of the bottom of the plow blade. Therefore, we propose a saline-alkali land deep tillage device to solve the above problems. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0026] Embodiment 1:

[0027] See also Figure 1-Figure 5 A deep tillage device for saline-alkali land comprises a plow support 1, on which a plurality of deep tillage mechanisms 2 with the same structure are fixedly mounted, the deep tillage mechanisms 2 comprising a group of arc-shaped reinforcing plates 3, and a group of arc-shaped reinforcing plates 3 are fixedly mounted by a group of clamps 4, an adjusting plate section 5 is arranged at the bottom of one of the arc-shaped reinforcing plates 3, and a plow blade 6 is arranged at one side of the adjusting plate section 5, a rotating groove 501 is opened at the bottom of the adjusting plate section 5, and an ear piece is fixedly welded at the bottom of the side wall of the plow blade 6 at the position of the rotating groove 501, and the ear piece is rotatably connected to the inside of the rotating groove 501 through a pin shaft;

[0028] An arc-shaped support arm 7 is fixedly welded on the side wall of one of the clamps 4 at the bottom, and an internal threaded hole is provided at the bottom of the arc-shaped support arm 7, and an adjusting screw 8 is threadedly connected to the inner thread of the internal threaded hole. A limit card cover 801 is fixedly welded to the end of one end of the adjusting screw 8, and a limit hole 601 is provided on the plow blade 6 at the position of the corresponding limit card cover 801. The limit hole 601 and the limit card cover 801 are connected by a supporting spring 9. A group of gear-shaped ear pieces 10 are fixedly welded on the top of the adjusting plate section 5, and the axis of the group of gear-shaped ear pieces 10 is rotatably connected to the two sides of the bottom of the corresponding arc-shaped reinforcement plate 3 through a pin shaft 2. A clamping piece 11 is clamped on the tooth mouth of a group of gear-shaped ear pieces 10, and a pin shaft 3 is rotatably connected to the top of the clamping piece 11, and one end of the pin shaft 3 is fixedly welded to the outer side of the corresponding arc-shaped reinforcement plate 3.

[0029] The operating principle of this saline-alkali land deep tillage device is:

[0030] First, the plow support 1 is installed on the corresponding lifting support arm at the rear of the tractor through a latch to ensure that the lifting arm of the tractor can drive the overall lifting of the plow support 1. At this time, the tractor can be driven to the saline-alkali land for deep plowing. During the plowing process, when the bottom of the plow blade 6 of the deep plowing mechanism 2 hits a stone, the bottom of the plow blade 6 will automatically deflect and swing backward by a certain amplitude due to the resistance of the stone, and the top of the plow blade 6 will be deflected forward to squeeze the support spring 9, so that the plow blade 6 has a certain redundant avoidance space to avoid the bottom of the plow blade 6 from hard contact with the stone. At the same time, before plowing, the distance between the adjusting screw 8 and the plow blade 6, that is, the distance between the limit card cover 801 and the limit hole 601, can be rotated to adjust the support force of the support spring 9, which is convenient to use.

[0031] When it is necessary to adjust the angle of the plow blade 6 of each deep plowing mechanism 2, it is only necessary to lift the corresponding set of clamps 11 first to disengage them from the contact and engagement state with the set of gear-shaped ear pieces 10. At this time, the adjusting plate segment 5 can drive the plow blade 6 to swing arbitrarily on the arc-shaped reinforcing plate 3. When the swing adjustment angle meets the use requirements, the clamp 11 can be clamped on the gear-shaped ear piece 10 again. At this time, the adjusting plate segment 5 can complete the fixing of the adjusted angle, and the operation is simple.

[0032] Embodiment 2:

[0033] In view of the above embodiment 1, for further description, refer to Figure 2 A group of clips 12 are arranged at the top end of a group of arc-shaped reinforcing plates 3, and the top end of a group of arc-shaped reinforcing plates 3 is fixed on the plow bracket 1 through a group of clips 12 and an extension bolt. The side of the plow blade 6 is an arc-shaped structure, and the top and bottom of the plow blade 6 are both provided with a cone tip.

[0034] By setting a group of clips 12, the top ends of a group of arc-shaped reinforcement plates 3 of the deep plowing mechanism 2 can be firmly fixed on the plow bracket 1, and the installation structure is more stable. The side of the plow blade 6 is an arc-shaped structure, and the top and bottom of the plow blade 6 are both provided with conical tips, which makes it easier to insert into the soil for deep plowing operations.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
