Description

Technical Field

[0001] This utility model relates to a ditching device, belonging to the field of agricultural machinery and equipment. Background Technology

[0002] Ditch openers are key pieces of equipment in agricultural planting. Working in conjunction with machinery, they efficiently dig planting and drainage ditches, saving manpower and time. Planting and drainage ditches are essential in crop cultivation; however, because drainage ditches are wider and deeper than planting ditches, different ditch openers are needed to dig the two types of ditches. In practice, machinery is typically used to dig one type of ditch in the field first, then a different type of ditch is used to dig the other type. This process requires multiple digging attempts, which is not only inefficient but also prone to causing excessive soil compaction, hindering crop growth. Utility Model Content

[0003] The purpose of this invention is to provide a ditching device that can simultaneously dig planting ditches and drainage ditches in a single operation, significantly improving ditching efficiency.

[0004] This utility model is achieved through the following technical solution.

[0005] A trenching device includes a first mounting shaft, a plurality of trenching wheels rotatably connected to the first mounting shaft for trenching planting trenches, and a trenching shovel mounted on the first mounting shaft for trenching drainage trenches; the trenching shovel is mounted in the middle of the first mounting shaft, the trenching wheels are respectively located on both sides of the trenching shovel, and the plurality of trenching wheels located on both sides of the trenching shovel are symmetrically arranged relative to the trenching shovel.

[0006] As a further improvement of this utility model, it also includes a second mounting shaft fixedly connected to the first mounting shaft. The second mounting shaft is located above the first mounting shaft. The first mounting shaft is movably connected to the rear end of the trenching shovel, so that the front end of the trenching shovel can rotate around the first mounting shaft. The second mounting shaft is connected to the rear end of the trenching shovel, and the connection position between the second mounting shaft and the trenching shovel is adjustable along the height direction to adjust the depth of the excavated drainage ditch.

[0007] As a further improvement of this utility model, the second mounting shaft is connected to the trenching shovel through a connecting plate. The trenching shovel is provided with a first connecting hole, and the connecting plate is provided with a plurality of second connecting holes corresponding to the first connecting hole. The connecting holes are distributed at intervals along the rotation trajectory of the trenching shovel. The fastening component passes through the corresponding first connecting hole and one of the second connecting holes to realize the detachable and fixed connection between the trenching shovel and the connecting plate.

[0008] As a further improvement of this utility model, the trenching shovel includes a base plate and two side plates respectively disposed on the left and right sides of the base plate, the front ends of the two side plates intersecting to form a shovel tip for breaking the soil.

[0009] As a further improvement of this utility model, the included angle between the two side plates at the front end is an acute angle.

[0010] As a further improvement of this utility model, a reinforcing plate is provided on the rear side of the base plate, and the left and right sides of the reinforcing plate are respectively connected to the rear sides of the two side plates.

[0011] As a further improvement of this utility model, a mounting hole is provided at the center of the trenching wheel, through which the main shaft passes for installation, and the trenching wheel is rotatably sleeved on the first mounting shaft.

[0012] As a further improvement of this utility model, two limiting sleeves are fitted on the first mounting shaft for each of the trenching wheels. The two limiting sleeves are located on both sides of the corresponding trenching wheel to limit the position of the trenching wheel on the first mounting shaft.

[0013] As a further improvement of this utility model, the limiting sleeve has a through hole extending along the axial direction and an adjustable mounting notch. The limiting sleeve can be compressed and contracted. The limiting sleeve at both sides of the mounting notch is provided with corresponding screw holes and screw connectors. The rotation of the screw connectors is used to adjust the size of the mounting notch, so as to adjust the size of the through hole.

[0014] As a further improvement of this utility model, the grooved wheel is disc-shaped and hollow inside.

[0015] The beneficial effects of this utility model are: 1. The trenching wheel is responsible for digging shallower planting trenches, while the trenching shovel is responsible for digging deeper drainage trenches. The trenching wheel and trenching shovel are integrated on the first mounting shaft, which can dig planting trenches and drainage trenches simultaneously in a single operation. Compared with traditional equipment, this avoids the need for multiple field visits and replacement of trenching tools, which not only significantly improves work efficiency but also prevents the soil from being over-compacted.

[0016] 2. The trenching wheels are symmetrically distributed around the trenching shovel as the axis. On the one hand, this offsets the eccentric load moment when operating on one side, reducing the risk of equipment tipping over. On the other hand, it can prevent the trenches from collapsing or tilting, ensuring the consistency of the trench size. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0019] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0020] This embodiment provides a ditching device for cultivating planting ditches and drainage ditches in farmland, as shown in the following figure. Figures 1-6 The device includes a first mounting shaft 1, multiple trenching wheels 2 rotatably connected to the first mounting shaft 1 for trenching planting trenches, and trenching shovels 3 mounted on the first mounting shaft 1 for trenching drainage trenches. The trenching shovels 3 are mounted in the middle of the first mounting shaft 1, and the trenching wheels 2 are located on both sides of the trenching shovels 3, with the multiple trenching wheels 2 on both sides of the trenching shovels 3 arranged symmetrically relative to the trenching shovels 3.

[0021] In this embodiment, the trenching wheel 2 is responsible for cultivating shallow planting trenches, and the trenching shovel 3 is responsible for cultivating deeper drainage trenches. The trenching wheel 2 and the trenching shovel 3 are integrated on the first mounting shaft 1, which can cultivate planting trenches and drainage trenches simultaneously in a single operation. Compared with traditional equipment that requires multiple field visits and replacement of different types of trenching tools, this not only significantly improves the efficiency of operation, but also avoids excessive soil compaction.

[0022] The trenching wheels 2 are symmetrically distributed around the trenching shovel 3 as the axis. On the one hand, this offsets the eccentric load moment when operating on one side, reduces the risk of mechanical equipment tipping over, and helps improve the stability of mechanical equipment operation. On the other hand, it can prevent the trenches from collapsing or tilting, and ensure the consistency of the trench size.

[0023] In this embodiment, a second mounting shaft 4 is also included. The second mounting shaft 4 is fixedly connected to the first mounting shaft 1, so that when the second mounting shaft 4 moves, it can drive the first mounting shaft 1 to move. The second mounting shaft 4 is located above the first mounting shaft 1. The first mounting shaft 1 is movably connected to the rear end of the trenching shovel 3, so that the front end of the trenching shovel 3 can rotate around the first mounting shaft 1. The second mounting shaft 4 is connected to the front end of the trenching shovel 3, and the connection position between the second mounting shaft 4 and the trenching shovel 3 is adjustable along the height direction to adjust the depth of the drainage ditch.

[0024] The first mounting shaft 1 here can be fixedly connected to the second mounting shaft 4 by two connecting rods 42. Preferably, the two connecting rods 42 can be detachably connected to the two ends of the first connecting rod 42 by bolts for easy installation.

[0025] It should be noted that when carrying out soil trenching operations, the second mounting shaft 4 can be moved manually or by mechanical equipment that can move in the farmland, thereby moving the first mounting shaft 1, so as to simultaneously cultivate planting trenches and drainage trenches in the farmland.

[0026] Specifically, the second mounting shaft 4 is connected to the trenching shovel 3 via a connecting plate 41. The trenching shovel 3 has a first connecting hole 51. The upper end of the connecting plate 41 is fixedly connected to the second mounting shaft 4. The connecting plate 41 has multiple second connecting holes 52 corresponding to the first connecting hole 51. The multiple second connecting holes 52 are distributed at intervals along the rotation trajectory of the trenching shovel 3. Fastening components 53 pass through the corresponding first mounting holes 21 and second mounting holes 21 to achieve a detachable connection between the trenching shovel 3 and the connecting plate 41. Different second connecting holes 52 correspond to different heights. Here, the fastening component 53 is a bolt, and the bolt is equipped with a nut 71 to fix the trenching shovel 3 to the connecting plate 41.

[0027] In addition, since the drainage ditch is deeper and wider than the planting ditch, it is necessary to ensure that the trenching shovel 3 has a greater digging force on the soil than the trenching wheel 2.

[0028] In this embodiment, the trenching shovel 3 includes at least a base plate 31 and two side plates 32 respectively disposed on both sides of the base plate 31. The two side plates 32 intersect at the front end to form a shovel tip for breaking the soil. Furthermore, the included angle between the two side plates 32 when they intersect at the front end is an acute angle, which makes the shape of the shovel tip relatively sharp, which helps to reduce the soil penetration resistance of the trenching shovel 3, thereby quickly cutting the soil.

[0029] The trenching shovel 3 also includes a reinforcing plate 33, which is located on the rear side of the base plate 31. The left and right sides of the reinforcing plate 33 are respectively connected to the rear sides of the two side plates 32. The reinforcing plate 33 helps to improve the overall structural strength of the trenching shovel 3 and prevents soil from entering the interior of the trenching shovel 3 during trenching. The base plate 31, the two side plates 32, and the reinforcing plate 33 in the trenching shovel 3 can all be made of stamped stainless steel, and the base plate 31 can be welded to the side plates 32 and the reinforcing plate 33.

[0030] It should be noted that the specific connection method between the trenching shovel 3 and the first mounting shaft 1 can be to open a round hole 32a on the rear part of the side plate 32 of the trenching shovel 3, and pass the first mounting shaft 1 through the round hole 32a, so that the trenching shovel 3 can rotate relative to the first mounting shaft 1.

[0031] In this embodiment, the trenching wheel 2 is disc-shaped, and an installation hole 21 is provided at the center of the trenching wheel 2. The main shaft passes through the installation hole 21 for installation. The trenching wheel 2 is rotated and sleeved on the first installation shaft 1. During operation, the trenching wheel 2 is partially embedded in the soil. When the first installation shaft 1 moves horizontally, the trenching wheel 2 rolls and trenches under the combined action of the friction of the soil and the horizontal thrust of the first installation shaft 1.

[0032] In addition, the hollow interior of the furrowing wheel 2 reduces its weight, which helps reduce the labor intensity of farmers or the energy consumption of machinery.

[0033] In this embodiment, two limiting sleeves 6 are provided on the first mounting shaft 1 for each trenching wheel 2. The two limiting sleeves 6 are located on both sides of the corresponding trenching wheel 2, and are used to limit the position of the trenching wheel 2 on the first mounting shaft 1 to ensure that the position of the trenching wheel 2 is accurate.

[0034] Meanwhile, to facilitate the positioning of the trenching wheel 2 on the first mounting shaft 1, an adjustable limiting sleeve 6 is provided. Specifically, the limiting sleeve 6 has an axially extending through hole 61 and an adjustable mounting notch 62. Corresponding screw holes and screw connectors 72 are provided on both sides of the mounting notch 62. The rotation of the screw connectors 72 is used to adjust the size of the mounting notch 62, thereby adjusting the size of the through hole 61. When the diameter of the through hole 61 is larger than that of the first mounting shaft 1, the limiting sleeve 6 can move relative to the first mounting shaft 1; when the diameter of the through hole 61 is smaller than that of the first mounting shaft 1, the limiting sleeve 6 is fixed on the first mounting shaft 1. It should be noted that the limiting sleeve 6 should be made of a deformable and recoverable material to ensure that the size of the mounting notch 62 is adjustable.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
