Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a no-till seeder for grasslands. Background Technique

[0002] A no-till seeder for grasslands is an agricultural machine used for reseeding grass in grasslands. It usually consists of a tractor, a furrow opener, a seeding device, a soil covering device, etc. The working principle of the furrow opener is that the tractor drives the furrow opener to cut the soil and create a groove, while the seeding device scatters seeds into the groove, and then the soil covering device covers the soil on the seeds. This mechanized operation method can improve seeding efficiency, reduce the disturbance and damage to the soil, and is beneficial to the restoration and protection of the grassland ecosystem.

[0003] The existing no-till seeder for grasslands is improved on the basis of a no-till seeder. Reducing the size of the seed metering device and adding a weed deflector facilitate the grass seeds to fall to the ground. However, the spacing of the furrow openers of the existing no-till seeder for grasslands is too large, resulting in relatively sparse distribution of grass seeds. Content of the Utility Model

[0029] Embodiment 1:

[0030] Please refer to Figures 1-5 , and the present invention details the above technical solutions through the following embodiments:

[0031] A no-till seeding machine for grasslands, comprising:

[0032] A seeding machine 1, the seeding machine 1 includes a vehicle frame, several grass seed boxes 14 are provided on the top of the vehicle frame, a seed metering device 15 is connected below each grass seed box 14 through a pipeline, a seed metering hose 16 is connected to the discharge port of the seed metering device 15, a ditching assembly 2 is provided at the tail of the vehicle frame, and a soil compressing assembly 3 is provided at the tail of the ditching assembly 2;

[0033] The grass seed box 14 is used for storing grass seeds, and the seed metering device 15 adopts a well-known suction type seed metering device.

[0034] The grass seeds in the grass seed box 14 are transported to the seed metering device 15 through a pipeline, the seed metering device 15 transports the grass seeds evenly one by one to the seed metering hose 16, and the grass seeds slide down along the seed metering hose 16 to the ground.

[0035] The frame includes a connecting frame 11. An installation frame 12 is welded and installed at the tail end of the connecting frame 11. The grass seed box 14 is uniformly fixed and installed at the top of the installation frame 12 through bolts. Driving wheels 13 are rotatably installed at the bottoms of both ends of the installation frame 12.

[0036] The connecting frame 11 is used to connect with a tractor, and the driving wheels 13 can facilitate the movement of the equipment.

[0037] The ditching assembly 2 includes a connecting shaft 23. A plurality of sliding sleeves 25 are slidably installed on the connecting shaft 23. A ditching device is connected below each sliding sleeve 25. A regulating spring 27 is sleeved on the connecting shaft 23 and located between the sliding sleeves 25. Adjusting sleeves 28 are threadedly connected to both ends of the connecting shaft 23.

[0038] The elastic force of the regulating spring 27 drives the sliding sleeves 25 to move towards the ends of the connecting shaft 23 until they contact the adjusting sleeves 28 and stop moving under the block of the adjusting sleeves 28. Under the elastic force of the regulating spring 27, the distances between the sliding sleeves 25 are kept equal. By rotating the adjusting sleeves 28, the adjusting sleeves 28 can move along the connecting shaft 23, thereby changing the distances between the sliding sleeves 25.

[0039] Rotating frames 21 are fixedly installed at both ends of the connecting shaft 23. The rotating frames 21 are fixedly connected to the installation frame 12. A lifting oil cylinder 22 is rotatably connected to the middle of the rotating frame 21. The tail end of the cylinder body of the lifting oil cylinder 22 is rotatably connected to the installation frame 12.

[0040] Controlling the lifting oil cylinder 22 to work can drive the rotating frame 21 to rotate, thereby controlling the height of the connecting shaft 23.

[0041] A limiting groove 24 is formed through the surface of the connecting shaft 23. The sliding sleeves 25 are clamped with the limiting groove 24 and can slide along the limiting groove 24.

[0042] The limiting groove 24 is used to limit the sliding direction of the sliding sleeves 25 and prevent the sliding sleeves 25 from rotating.

[0043] The ditching device includes a ditching frame 26. The ditching frame 26 is vertically welded and installed below the sliding sleeve 25. Ditching wheels 29 are symmetrically and rotatably installed at the bottom end of the ditching frame 26, and the lower edges of the ditching wheels 29 are in contact with each other.

[0044] When the device moves, the ditching wheels 29 contact the ground and will cut a ditch on the ground surface. When the distances between the sliding sleeves 25 change, the distances between the ditching frames 26 will also change. Thus, the distances between the ditches cut will change.

[0045] The seed discharging hose 16 is fixed to the back of the ditching frame 26 through a buckle, and the outlet at the tail end of the seed discharging hose 16 is located between the two ditching wheels 29.

[0046] The outlet position of the seed - metering hose 16 can change following the position of the ditching frame 26, so as to ensure that the seeds can fall into the ditch cut by the ditching wheel 29.

[0047] The soil - pressing assembly 3 includes a downward - pressing frame 31. At the bottom of the downward - pressing frame 31, a soil - pressing frame 32 is rotatably installed. At the tail end of the soil - pressing frame 32, a pressing wheel 34 is rotatably installed. A downward - pressing spring 33 is fixedly installed between the downward - pressing frame 31 and the soil - pressing frame 32. The pressing wheel 34 is used to compact the soil. The downward - pressing frame 31 is located behind the ditching frame 26, and the head of the downward - pressing frame 31 is fixedly connected to the ditching frame 26.

[0048] The downward - pressing frame 31 can move following the ditching frame 26. The elastic force of the downward - pressing spring 33 can drive the soil - pressing frame 32 to move downward, so as to ensure that the pressing wheel 34 is in close contact with the ground. When the device moves, the pressing wheel 34 can compact the soil cut by the ditching wheel 29.

[0049] In this embodiment, when the operator uses this equipment, connect the connecting frame 11 to the tractor and fill the grass - seed box 14 with grass seeds.

[0050] Rotate the adjusting spring 27 to control the distance between the sliding sleeves 25, thereby controlling the distance between the ditching frame 26 and the soil - pressing assembly 3.

[0051] Control the lifting oil cylinder 22 to work, drive the rotating frame 21 to rotate downward until the ditching wheel 29 inserts into the ground. At this time, under the action of the elastic force of the downward - pressing spring 33, the pressing wheel 34 is in close contact with the ground.

[0052] Use the tractor to drag the device to move, start the seed - metering device 15, and evenly send the grass seeds in the grass - seed box 14 into the seed - metering hose 16 one by one.

[0053] As the device moves, the ditching wheel 29 cuts a ditch on the ground. The grass seeds fall into the ditch from the outlet of the seed - metering hose 16. Immediately afterwards, the pressing wheel 34 presses over the ditch, squeezing the soil on both sides of the ditch inward and compacting it. Thus, reseeding is realized.

[0054] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above - mentioned embodiments. The above - mentioned embodiments and the descriptions in the specification are only preferred examples of the present utility model, and do not limit the present utility model.
