Description

Technical Field

[0001] This utility model belongs to the field of farmland construction technology, specifically relating to a trenching and ditching device for high-standard farmland construction. Background Technology

[0002] Farmland infrastructure construction refers to the construction of facilities on the land using engineering or biological measures to develop agricultural production and ensure long-term production benefits. It encompasses all measures taken to transform and develop farmland in order to utilize and modify nature, develop agricultural production, and achieve stable and high yields.

[0003] According to a patent website, a trenching and grooving device for farmland construction (authorization announcement number: CN) is disclosed. As described in 221118607U, "This utility model discloses a trenching and ditching device for farmland construction, including a support and an adjustable compaction device. The adjustable compaction device, through the reciprocating meshing of a rack and pinion, drives a rotating plate inside a push-pull assembly. This rotating plate, in conjunction with connecting rods connected at the front and rear, and support bars at the front and rear, enables relative or opposite lateral movement of sliding strips on both sides. Thus, the trenching and compaction blades located on both sides of the lower end of the housing can reciprocate laterally in one go to compact the soil on both sides of the trench, achieving a one-time transmission and compaction combination, improving trenching and ditching efficiency. Furthermore, an adjustment component is provided, through intermittent transmission of the turntable, cam shaft, and intermittent disc, allowing adjustment of the angle of the bottom trenching and compaction blades. This enables different trench compaction conditions and lateral pushing of soil within the trench for trenching, achieving flexible adjustment of the trenching and compaction blade angle to cope with different trench compaction conditions."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] The trenching and grooving device used for farmland construction cannot adjust the spacing of the trenching teeth during use, thus making it unable to make flexible adjustments when trenching and grooving different crops, reducing the device's flexibility.

[0006] To address the aforementioned issues, this application proposes a trenching and ditching device for high-standard farmland construction. Utility Model Content

[0007] To address the aforementioned problems in the existing technology, this utility model provides a trenching and ditching device for high-standard farmland construction, which is easy to adjust.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a trenching and ditching device for high-standard farmland construction, comprising a traction frame, wherein the traction frame includes:

[0009] A fixing groove is fixedly connected to the right side of the traction frame. A limit mechanism is provided at the top of the fixing groove, and an adjustment mechanism is provided inside the fixing groove. The adjustment mechanism includes:

[0010] A threaded rod is rotatably connected to the inner wall of a fixed groove. A worm gear is fixedly connected to the outer wall of the threaded rod, and a worm is meshed with the outer ring of the worm gear. A second protrusion is threadedly connected to the outer wall of the threaded rod. A connecting plate is fixedly connected to the right side of the second protrusion. A first grooving tool is fixedly connected to the right side of the connecting plate. A fixed frame is fixedly connected to the outer side of the fixed groove, and the second grooving tool is fixedly connected to the right side of the fixed frame.

[0011] Preferably, the bottom end of the worm is rotatably connected to the bottom of the inner wall of the fixed groove, and a handwheel is fixedly connected to the top end of the worm, so that the worm can be rotated by the handwheel.

[0012] Preferably, a rotating hole is provided at the top of the fixed groove, and the worm gear is rotatably connected to the inner wall of the rotating hole to provide stable support for the worm gear.

[0013] Preferably, the threads on the outer walls at both ends of the threaded rod are in opposite directions, and the second protrusion is slidably connected to the inner wall of the fixed groove, so that the rotational motion of the threaded rod is converted into the linear motion of the second protrusion.

[0014] Preferably, the limiting mechanism includes a fixed box, which is fixedly connected to the top of the fixed groove. A spring is fixedly connected to the inner wall of the fixed box. A protrusion is fixedly connected to the top of the spring. A connecting shaft is fixedly connected to the top of the protrusion. A pressing plate is fixedly connected to the top of the connecting shaft. An internal spline is fixedly connected to one side of the protrusion. An external spline engages with the inner ring of the internal spline to ensure the stability of the adjustment.

[0015] Preferably, the external spline is fixedly connected to the outer wall of the worm, and the first protrusion is slidably connected to the inner wall of the fixed box, so that the first protrusion can move stably to compress the spring.

[0016] Preferably, a circular hole is provided on the top of the fixed box, and the connecting shaft passes through the circular hole, so that the connecting shaft can move through the circular hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this utility model, the limiting mechanism allows the second protrusion to move through the connecting plate, causing the first trenching cutter to move further away from the second trenching cutter. This allows for adjustment of the distance between the first and second trenching cutters, enabling flexible adjustments when trenching different crops. This enhances the flexibility of the device and facilitates trenching work in high-standard farmland construction.

[0019] In this invention, the worm is in a rotatable state through the adjustment mechanism. Similarly, when the internal spline and external spline are engaged, the worm is in a non-rotatable state. This ensures that the worm will not be affected by external factors and will not rotate, thereby improving the stability of the adjustment and ensuring the smooth operation of the adjustment.

[0020] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0028] Example

[0029] Please see Figures 1-4 This utility model provides the following technical solution: a trenching and ditching device for high-standard farmland construction, including a traction frame 1, the traction frame 1 comprising:

[0030] Fixed groove 2 is fixedly connected to the right side of traction frame 1. A limit mechanism 3 is provided at the top of fixed groove 2, and an adjustment mechanism 4 is provided inside fixed groove 2. The adjustment mechanism 4 includes:

[0031] A threaded rod 41 is rotatably connected to the inner wall of the fixed groove 2. A worm gear 42 is fixedly connected to the outer wall of the threaded rod 41. A worm 43 is meshed with the outer ring of the worm gear 42. A second protrusion 44 is threadedly connected to the outer wall of the threaded rod 41. A connecting plate 45 is fixedly connected to the right side of the second protrusion 44. A first grooving tool 46 is fixedly connected to the right side of the connecting plate 45. A fixed frame 47 is fixedly connected to the outer side of the fixed groove 2. A second grooving tool 48 is fixedly connected to the right side of the fixed frame 47.

[0032] Furthermore, the bottom end of the worm 43 is rotatably connected to the bottom of the inner wall of the fixed groove 2, and a handwheel is fixedly connected to the top end of the worm 43, so that the worm 43 can be rotated by the handwheel.

[0033] Furthermore, a rotating hole is provided at the top of the fixed groove 2, and the worm 43 is rotatably connected to the inner wall of the rotating hole to provide stable support for the worm 43.

[0034] Furthermore, the threads on the outer walls of the two ends of the threaded rod 41 are in opposite directions, and the second protrusion 44 is slidably connected to the inner wall of the fixed groove 2, so that the rotational motion of the threaded rod 41 is converted into the linear motion of the second protrusion 44.

[0035] Furthermore, the limiting mechanism 3 includes a fixed box 31, which is fixedly connected to the top of the fixed groove 2. A spring 32 is fixedly connected to the inner wall of the fixed box 31. A protrusion 33 is fixedly connected to the top of the spring 32. A connecting shaft 34 is fixedly connected to the top of the protrusion 33. A pressing plate 35 is fixedly connected to the top of the connecting shaft 34. An internal spline 36 is fixedly connected to one side of the protrusion 33. An external spline 37 engages with the inner ring of the internal spline 36 to ensure the stability of the adjustment.

[0036] Furthermore, the external spline 37 is fixedly connected to the outer wall of the worm gear 43, and the protrusion 33 is slidably connected to the inner wall of the fixed box 31, so that the protrusion 33 can move stably to compress the spring 32.

[0037] Furthermore, a circular hole is provided on the top of the fixed box 31, through which the connecting shaft 34 passes, allowing the connecting shaft 34 to move through the circular hole.

[0038] The working principle and usage process of this utility model are as follows: First, the traction frame 1 is connected and installed with the traction equipment. When it is necessary to adjust the distance between the first ditching cutter 46 and the second ditching cutter 48 according to different crops, the pressing plate 35 can be pressed down first. The pressing plate 35 can drive the first protrusion 33 to move through the connecting shaft 34. The first protrusion 33 can compress the spring 32. The first protrusion 33 can drive the inner spline 36 and the outer spline 37 to disengage. At this time, the worm 43 is in a rotatable state. Similarly, when the inner spline 36 and the outer spline 37 are engaged, the worm 43 is in a non-rotatable state. This ensures that the worm 43 will not be affected by external factors and will not rotate, further improving the stability of the adjustment and ensuring the smooth progress of the adjustment work.

[0039] When the worm 43 is in a rotatable state, the handwheel can be turned to rotate the worm 43. Since the worm 43 and the worm wheel 42 are meshed, the worm wheel 42 will drive the threaded rod 41 to rotate. Since the threaded rod 41 and the second protrusion 44 are threadedly connected, the second protrusion 44 can slide and limit its movement on the inner wall of the fixed groove 2. And since the threads on the outer walls of the two ends of the threaded rod 41 are opposite, the second protrusion 44 will drive the first trenching cutter 46 to move through the connecting plate 45. The two first trenching cutters 46 will move away from the second trenching cutter 48 respectively. The distance between the first trenching cutter 46 and the second trenching cutter 48 can be adjusted, so that it can be flexibly adjusted when facing different crops, enhancing the flexibility of the device and facilitating the trenching work of high-standard farmland construction.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
