Description

Technical Field

[0001] The invention relates to the field of furrow openers for seed drills, and in particular to a furrowing structure for grassland seeding. Background Art

[0002] Grasslands in my country's alpine regions face serious ecological challenges. For example, surveys show that over 78% of the grasslands in Ganzi Prefecture have experienced varying degrees of degradation. This is particularly true for grasslands with convenient access, flat terrain, and suitable grazing conditions. Severely degraded grasslands can become rodent-infested, desertified, compacted, and densely populated with poisonous weeds, ultimately rendering them completely useless. Therefore, it is imperative to take necessary measures to address these ecological challenges. In recent years, Ganzi Prefecture has made significant efforts to restore the grassland ecosystem in its alpine pastoral areas, but progress has been slow due to significant challenges such as low mechanization levels and a lack of suitable machinery for no-till reseeding. Chinese Invention Patent Publication No. CN2781735Y discloses a direct seeding machine that uses rotary tillage to create furrows. This machine consists of four main components: a strip-type rotary tillage and furrowing device, a fertilizer and seed discharge device, a seedbed treatment device, and a soil covering and compaction device. This type of direct seeding machine cannot adapt well to the natural environment of the grasslands in Ganzi Prefecture during production operations. When encountering stones on the surface and in the soil during operation, the strip rotary tillage and furrowing device cannot bounce up, which will affect the sowing operation. Summary of the Invention

[0003] In view of the above deficiencies in the prior art, the present invention aims to solve the problem of providing a furrowing structure for grassland sowing, in which a furrowing device can bounce up when encountering stones, so that the furrowing device can work continuously.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0022] Example 1

[0023] Reference Figure 1-4 As shown, an embodiment of the present invention provides a furrowing structure for grassland sowing, comprising a first main beam 1 and a second main beam 2 arranged in parallel. It should be noted that the first main beam 1 and the second main beam 2 are connected together at both ends by a first connecting member 3. Drive assemblies 4 are provided at both ends of the first main beam 1. Several furrowing assemblies 5 are provided on the first main beam 1 between the drive assemblies 4, wherein:

[0024] The trenching assembly 5 includes a mounting plate 51, a mounting seat 52, a connecting plate 53, a trenching disc assembly 54 and a shock-absorbing assembly 55. The mounting plate 51 is arranged on the first main beam 1 through a second connecting member 6. The mounting seat 52 is arranged on the mounting plate 51. The mounting seat 52 has an L-shaped portion. The shock-absorbing assembly 55 is arranged on the L-shaped portion. The connecting plate 53 is movably connected to one side of the mounting seat 52. The two ends of the connecting plate 53 are respectively movably connected to the central rotating shaft of the trenching disc assembly 54 and one end of the shock-absorbing assembly 55.

[0025] The working principle and usage process of this embodiment are as follows:

[0026] The furrowing structure for grassland sowing provided by the present invention forms a frame of a seeder through a first main beam 1 and a second main beam 2. The two ends of the first main beam 1 and the second main beam 2 are connected together by a first connecting member 3 to form a stable structure. It can be used by connecting it to a tractor. The tractor drives the driving component 4 to follow the movement, thereby driving the present invention to move. When the seeder drives forward and the furrowing component 5 hits a stone or other uneven road surface, the furrowing disc component 54 bounces upward and drives the connecting plate 53 to rotate around the movable connection point between the connecting plate 53 and the mounting seat 52. The rotation of the connecting plate 53 drives the shock absorbing component 55 to compress. The compression of the shock absorbing component 55 generates a rebound force to offset the impact force generated when the furrowing disc component 54 hits the stone.

[0027] Example 2

[0028] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment defines the specific structure of the trenching component 5, such as Figure 1-4 As shown, the trenching assembly 5 includes a trenching disc body 541 and a chuck 542. The two ends of the central rotating shaft of the trenching disc body 541 are movably connected to the connecting plate 53 and the chuck 542 respectively. The chuck 542 limits the lateral rotation of the trenching disc body 541, making the trenching disc body 541 move more smoothly.

[0029] Furthermore, the portion of the trenching disc 541 that contacts the ground is wavy, and the wavy trenching disc 541 has a larger trenching area and a better effect when in contact with the ground.

[0030] Example 3

[0031] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment defines the specific structure of the shock absorbing component 55, such as Figure 1-4 As shown, the shock absorbing assembly 55 includes a screw 551, a compression member 552 and a retaining ring 553. The compression member 552 is wound around the screw 551. One end of the screw 551 is movably connected to the connecting plate 53. The retaining ring 553 is arranged at the other end of the screw 551. When the ditching assembly 5 bounces upward, the connecting plate 53 drives the screw 551 to move, and the compression member 552 is compressed to generate a rebound force to offset the impact force.

[0032] Example 4

[0033] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment defines the specific structure of the first connecting member 3, such as Figure 1-4As shown, the first connecting member 3 includes a first vertical plate 31, a second vertical plate 32 and a horizontal plate 33. The two ends of the first vertical plate 31 are respectively connected to the first main beam 1 and the horizontal plate 33, and the two ends of the second vertical plate 32 are respectively connected to the second main beam 2 and the horizontal plate 33. Through this setting, the connection between the first main beam 1 and the second main beam 2 is tighter, and it is also convenient for subsequent connection with the tractor.

[0034] Example 5

[0035] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment defines the specific structure of the second connecting member 6, such as Figure 1-4 As shown, the second connecting member 6 includes a fixing plate 61 and a C-shaped member 62. The fixing plate 61 is arranged on the side of the first main beam 1 facing the movement direction of the ditching assembly 5. The C-shaped member 62 is fastened to the first main beam 1 and its two ends are connected to the fixing plate 61. By inserting the mounting plate 51 between the fixing plate 61 and the first main beam 1 and then fastening the C-shaped member 62 to the first main beam 1, the mounting plate 51 is connected and tightened, thereby ensuring the connection and tightening of the ditching assembly 5.

[0036] Example 6

[0037] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment discloses the specific structure of the driving component 4, such as Figure 1-4 As shown, the driving assembly 4 includes a ground wheel 41 and a wheel arm 42. The upper end of the wheel arm 42 is connected to the seed drill frame, and the ground wheel 41 is rotatably mounted on the lower end of the wheel arm 42 via the ground wheel 41 shaft.
