Description

Technical Field

[0001] The utility model relates to the technical field of no-tillage reseeding machines, in particular to a no-tillage reseeding machine for degraded and desertified grasslands. Background Art

[0002] No-till reseeding is a key technology for revegetation in degraded grasslands. Its purpose is to improve productivity and species diversity in degraded grasslands by reseeding appropriate, selected grass species without damaging or minimizing grassland vegetation. To improve reseeding efficiency, a no-till reseeder is often used.

[0003] In existing technology, no-till seeding machines are an improvement on no-till seeders and typically consist of a tractor, a furrow opener, a seeding device, and a covering device. The working principle of a furrow opener is that the tractor drives the furrow opener, causing it to cut the soil and create a furrow. Simultaneously, the seeding device sows the seeds into the furrow, and the covering device covers the seeds with soil. During seeding, the seeds are not watered. When seeding on degraded or desertified grassland, evaporation is high, making germination difficult and resulting in a low germination rate. Utility Model Content

[0029] Example 1:

[0030] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0031] A no-tillage reseeding machine for degraded desertified grassland, comprising:

[0032] The frame 1 includes a mobile frame 12, and mobile wheels 13 are rotatably installed at the bottom of both sides of the mobile frame 12. A seeding component is provided in the middle of the top surface of the mobile frame 12, and the seeding component is connected to the overseeding component 2. The seeding component is used to provide grass seeds to the overseeding component 2 in a quantitative manner. A watering component 3 is provided on the rear side of the mobile frame 12.

[0033] The moving wheels 13 are used for moving the device.

[0034] A traction frame 11 is welded to the front side of the mobile frame 12, and the traction frame 11 is used to connect with the traction equipment.

[0035] The traction equipment can be a well-known agricultural tractor or the like.

[0036] The seeding assembly includes a seed box 14 , the bottom of the seed box 14 is connected to a seed meter 15 through a pipeline, the discharge port of the seed meter 15 is threadedly connected to a seeding pipe 16 , and the discharge port of the seeding pipe 16 is located behind the furrowing wheel 22 .

[0037] Seed box 14 is used for storing seeds. Seed metering device 15 adopts known air-conveying seed metering device.

[0038] A counter 17 is provided on the top of the seeding tube 16. When grass seeds pass through the counters 17, the counters 17 can generate a signal.

[0039] The counter 17 adopts a well-known photoelectric sowing sensor. When grass seeds pass through, they will block the photoelectric sensor, thereby generating a signal.

[0040] The overseeding component 2 includes a sowing frame 21, under which a furrowing wheel 22 is rotatably installed. The furrowing wheel 22 is used to furrow on the grass. A pressing wheel 24 is provided behind the furrowing wheel 22. The pressing wheel 24 compacts the furrow opened by the furrowing wheel 22, and the seeds discharged by the seeding component fall between the furrowing wheel 22 and the pressing wheel 24.

[0041] The sowing rack 21 is fixedly installed on the bottom surface of the mobile rack 12 by bolts. When the traction rack 11 pulls the mobile rack 12 to move, it can drive the furrowing wheel 22 forward and squeeze the ground into a furrow. The seeding tube 16 is fixedly installed on the rear side of the mobile rack 12 by a tube clamp and is located between the furrowing wheels 22, so that the grass seeds can just fall into the furrow.

[0042] The pressing wheel 24 and the sowing frame 21 are rotatably connected via a rotating frame 23 , and a pressing spring 25 is connected between the top surface of the rotating frame 23 and the sowing frame 21 .

[0043] The elastic force of the suppression spring 25 drives the rotating frame 23 to rotate downward, thereby driving the suppression wheel 24 to press the ground tightly, which can squeeze the soil on both sides of the gully squeezed out by the ditching wheel 22 inward and cover the grass seeds.

[0044] The irrigation assembly 3 includes an irrigation bracket 31 , in which a water tank 33 is provided. The water tank 33 is used to store irrigation water. A stirring device is provided in the water tank 33 . An irrigation pipe 38 is provided below the water tank 33 , and the water outlet of the irrigation pipe 38 is located in front of the pressing wheel 24 .

[0045] The pouring bracket 31 is welded and installed at the rear of the movable frame 12 . Second movable wheels 32 are rotatably installed on both sides of the bottom of the pouring bracket 31 . The second movable wheels 32 are used to move the pouring bracket 31 .

[0046] Fertilizer or nutrient solution can be added into the water tank 33 to provide necessary nutrients for the growth of grass seeds.

[0047] The bottom of the watering pipe 38 is fixed between the rotating frames 23 by a pipe clamp, so that water can be poured on the grass seeds before the pressing wheel 24 presses the gully.

[0048] The stirring device includes a stirring roller 34 , which is rotatably installed in the water tank 33 , and one end of the stirring roller 34 passes through the water tank 33 and is connected to a stirring motor 35 .

[0049] When the stirring motor 35 is working, it can drive the stirring roller 34 to rotate, thereby stirring the water and fertilizer or nutrient solution in the water tank 33.

[0050] A liquid outlet 36 is provided at the bottom of the water storage tank 33 , a solenoid valve 37 is threadedly connected to the liquid outlet 36 , and the top of the irrigation pipe 38 is connected to the solenoid valve 37 .

[0051] When the electromagnetic valve 37 is energized, the water in the water tank 33 can enter the irrigation pipe 38 from the liquid outlet 36 through the electromagnetic valve 37 and then be discharged from the irrigation pipe 38.

[0052] When the electromagnetic valve 37 is powered off, the water in the water tank 33 cannot flow out.

[0053] When using the device in this embodiment, the operator connects the traction frame 11 to the traction device, and uses the traction device to drive the traction frame 11 to move, thereby driving the movable frame 12, the sowing frame 21 and the watering support 31 to move.

[0054] The sowing frame 21 moves, and the furrowing wheel 22 opens furrows on the ground. At the same time, the seed metering device 15 is controlled to work, and the grass seeds in the seed box 14 are quantitatively discharged. The discharged grass seeds fall into the furrows opened by the furrowing wheel 22 on the ground through the seeding tube 16.

[0055] At the same time, the stirring motor 35 is controlled to work, driving the stirring roller 34 to rotate, and stirring the water and fertilizer in the water tank 33.

[0056] When grass seeds pass counter 17, it generates a signal, which then controls solenoid valve 37 to energize for a specified period of time and then de-energize. This allows water from water tank 33 to be discharged from outlet 36 and into irrigation pipe 38. When the grass seeds fall into the gully, the water in irrigation pipe 38 just reaches the grass seeds. The energization time of solenoid valve 37 determines the amount of water applied.

[0057] After watering, the pressing wheel 24 passes over the grass seeds, squeezing the soil on both sides inwards and covering the grass seeds.

[0058] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
