Description

Technical Field

[0001] This utility model relates to the field of furrow openers for seeders, and specifically to furrow opening structures used for grassland sowing. Background Technology

[0002] my country's high-altitude grasslands face serious ecological problems. Taking Ganzi Prefecture as an example, according to surveys, over 78% of the grasslands in Ganzi Prefecture have experienced varying degrees of degradation, especially those with convenient transportation, flat terrain, and easy grazing. Severely degraded grasslands will evolve into rodent-infested wastelands, sandy lands, compacted lands, and areas densely populated with poisonous weeds, eventually losing all usability. Therefore, taking necessary measures to address these ecological problems has become urgent. In recent years, Ganzi Prefecture has done a great deal of work on the ecological restoration of grasslands in high-altitude pastoral areas, but progress has been slow due to prominent issues such as low levels of mechanization and a lack of suitable no-till reseeding equipment. Chinese invention patent CN2781735Y discloses a direct seeding machine that uses rotary tillage for ditching. This direct seeding machine mainly consists of four parts: a strip rotary tillage ditching device, a fertilizer and seed dispensing device, a seedbed treatment device, and a soil covering and compaction device. This type of direct seeding machine is not well adapted to the natural environment of the Ganzi Prefecture grasslands during production operations. When it encounters stones on the ground or in the soil, the strip rotary tillage and ditching device cannot spring up, which will affect the sowing operation. Utility Model Content

[0021] Example 1

[0022] Reference Figure 1-4 As shown, this utility model embodiment provides a furrowing structure for grassland sowing, including a first main beam 1 and a second main beam 2 arranged in parallel. It should be noted that the two ends of the first main beam 1 and the second main beam 2 are connected together by a first connector 3. Drive components 4 are provided at both ends of the first main beam 1, and a plurality of furrowing components 5 are provided on the first main beam 1 located between the drive components 4.

[0023] The trenching assembly 5 includes a mounting plate 51, a mounting base 52, a connecting plate 53, a trenching disc assembly 54, and a shock-absorbing assembly 55. The mounting plate 51 is mounted on the first main beam 1 via a second connector 6. The mounting base 52 is mounted on the mounting plate 51 and has an L-shaped portion 7. The shock-absorbing assembly 55 is mounted on the L-shaped portion 7. The connecting plate 53 is movably connected to one side of the mounting base 52, and both ends of the connecting plate 53 are movably connected to the central rotating shaft of the trenching disc assembly 54 and one end of the shock-absorbing assembly 55, respectively.

[0024] The trenching assembly 5 includes a trenching disc 541 and a chuck 542. The two ends of the central rotating shaft of the trenching disc 541 are movably connected to the connecting plate 53 and the chuck 542, respectively. The chuck 542 restricts the lateral rotation of the trenching disc 541, making the movement of the trenching disc 541 more stable.

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

[0026] The furrowing structure for grassland sowing provided by this utility model forms the frame of the seeder through the first main beam 1 and the second main beam 2. The two ends of the first main beam 1 and the second main beam 2 are connected together by the first connecting piece 3 to form a stable structure. It can be used after being connected to a tractor. The tractor moves forward, driving the drive component 4 to follow, thereby moving this utility model. When the furrowing component 5 hits a stone or other uneven road surface while the seeder is moving forward, the furrowing disc component 54 bounces up, causing the connecting plate 53 to rotate around the movable connection point between the connecting plate 53 and the mounting base 52. The rotation of the connecting plate 53 causes the shock absorption component 55 to be compressed. The compression of the shock absorption component 55 generates a rebound force, thereby offsetting the impact force generated when the furrowing disc component 54 hits a stone.

[0027] Example 2

[0028] This embodiment is an extension of the above embodiments. Specifically, as follows: Figure 1-4 As shown, the part of the trenching disc 541 that contacts the ground is wavy. The wavy trenching disc has a larger trenching area and better effect when it contacts the ground.

[0029] Example 3

[0030] This embodiment is based on the above embodiment. Specifically, this embodiment defines the specific structure of the shock absorption component 55, such as... Figure 1-4 As shown, the shock absorption 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 disposed at the other end of the screw 551. When the grooved assembly 5 springs upward, the connecting plate 53 drives the screw 551 to move, and the compression member 552 is compressed to generate a rebound force, thereby offsetting the impact force.

[0031] Example 4

[0032] This embodiment is based on the above embodiments. Specifically, this embodiment defines the specific structure of the first connector 3, such as... Figure 1-4As shown, the first connecting piece 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. This arrangement makes the connection between the first main beam 1 and the second main beam 2 more secure and also facilitates subsequent connection with the tractor.

[0033] Example 5

[0034] This embodiment is based on the above embodiment. Specifically, this embodiment defines the specific structure of the second connector 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 disposed on the side of the first main beam 1 facing the direction of movement of the trenching assembly 5. The C-shaped member 62 is fastened to the first main beam 1, with both ends 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 securely connected, thus ensuring the secure connection of the trenching assembly 5.

[0035] Example 6

[0036] This embodiment is based on the above embodiments. Specifically, this embodiment discloses the specific structure of the driver component 4, as follows: Figure 1-4 As shown, the drive assembly 4 includes a ground wheel 41 and a wheel arm 42. The upper end of the wheel arm 42 is connected to the seeder frame, and the ground wheel 41 is rotatably mounted on the lower end of the wheel arm 42 via a pivot shaft. The ground wheel 41 drives the movement of this invention.

[0037] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
