Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, in particular to a grain seeder capable of integrated fertilization, sowing and belt laying operations. Background Art

[0002] With the development of modern agriculture, especially in the water-scarce areas in central and western my country, the requirements for sowing, fertilizing and laying belts in the process of grain planting are getting higher and higher. The traditional method of sowing grains often requires multiple steps to complete, which is cumbersome and inefficient. In order to improve the efficiency and quality of grain sowing, the existing grain seeders can already achieve integrated operation, that is, complete the processes of sowing, fertilizing and laying belts in one operation. However, the existing grain seeders still have some problems in practical applications, such as uneven fertilization, inconsistent sowing depth, uneven suppression after laying belts, uneven dripping coverage and other problems. Therefore, in view of the shortcomings of the prior art, it is necessary to provide a grain seeder that can integrate fertilization, sowing and laying belts to solve the problems of uneven fertilization, inconsistent sowing depth, uneven surface after laying belts, and uneven dripping. Summary of the invention

[0003] In view of this, in order to solve the problems in the prior art such as uneven fertilization, inconsistent sowing depth, uneven ground surface after strip laying, uneven water dripping, etc., the utility model provides a grain seeder with integrated fertilization, sowing and strip laying, which can make fertilizer discharge and seeding more uniform, the sowing depth consistent, and subsequently suppress and smooth the entire sowing surface, so as to achieve more uniform water flow dispersion after dripping, thereby ensuring the consistency of seedling emergence.

[0004] To achieve the above object, the present invention provides the following technical solution: a grain seeder capable of integrated fertilization, sowing and belt laying, comprising:

[0005] The frame has a three-point suspension device at the front end for connecting with a tractor.

[0006] The ground wheel is located at both ends of the frame, the ground wheel itself can rotate, and its connecting frame can be adjusted up and down to control the height of the ground wheel relative to the upper plane of the frame. A driving sprocket is arranged on the ground wheel shaft of the ground wheel.

[0007] A seed fertilizer box is located above the frame, and is divided into two areas, one for seeds and one for fertilizers. A seed / fertilizer wheel is arranged below the seed fertilizer box, and the seed / fertilizer wheel is connected in series through a seed fertilizer box shaft, and a driven sprocket is arranged on the seed fertilizer box shaft. Each of the two areas of the seed fertilizer box has a set of the seed fertilizer box shaft and the driven sprocket.

[0008] The transmission mechanism is a transmission group composed of gears and sprockets arranged on both sides of the seed and fertilizer box, which can change the transmission direction and transmission ratio. It rotates the driving sprocket on the ground wheel and the driven sprocket on the seed and fertilizer box respectively through a chain to transmit the driving force of the ground wheel to the seed / fertilizer wheel.

[0009] A fertilizing / seeding disc device, the fertilizing / seeding disc device is composed of a traction frame, a spring, a disc, and a depth limiting ring, the depth limiting ring is cylindrical and fixed on the disc, and is concentric with the disc, and its diameter is smaller than the disc. The disc is rotatably connected to the traction frame, and the traction frame can be pressed downward under the action of the spring so that the disc can cut into the soil downward.

[0010] The drip irrigation device is composed of a drip irrigation frame and a tape laying device. The drip irrigation frame is fixed above the frame and is used to support the drip irrigation tape roll. The tape laying device is fixed below the frame. The drip irrigation tape passes through the tape laying device and is laid on the ground.

[0011] The pressing roller is cylindrical and rotatably connected to the bottom of the frame. The length of the pressing roller is adapted to the seeding / fertilizing area of ​​the fertilizing / seeding disc device and the pressing roller is located behind the fertilizing / seeding disc device. The pressing roller compacts the loose soil so that the seeds fit more closely to the soil.

[0012] The row brush is movably connected to the rear of the pressing roller, has a lateral length adapted to the pressing roller, and provides downward pressure through spring 2, and its function is to smooth the soil and part of the grooves opened by the fertilizing / seeding disc device, and cover some exposed seeds with soil.

[0013] Preferably, the method further comprises: the stripes on the seeding / fertilizing wheel are in a herringbone shape and are directed from the middle to both sides.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides a grain seeder that can perform fertilization, sowing and belt laying in one machine. The seed / fertilizer disc cuts into the soil under the action of a spring, and controls the depth of seeding / fertilization under the action of a depth-limiting ring on the disc, thereby ensuring that the depth of seeding / fertilization is consistent. The cylindrical pressing roller can compact the soil, so that the seeds are in closer contact with the soil, and the soil is more even without gullies. The surface is smoother under the leveling action of the rear brush, so that the water flow is more even during subsequent dripping, and there will not be a lot of water accumulation in low-lying areas and a lack of water in high places due to uneven ground. During the rotation of the "human" shaped seed / fertilizer wheel, there is a cavity on any cross section to accommodate seeds or fertilizers, so that the seeding / fertilization is more even.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The working principle of the utility model is as follows:

[0025] The frame 1 has a three-point suspension device at its front end for connecting with a tractor. The ground wheel 2 is arranged at both ends of the frame 1 and is rotatably connected with the frame 1 through a connecting frame 21. The connecting frame 21 can be adjusted up and down to control the height of the ground wheel 2 relative to the upper plane of the frame 1, and is used to adjust the height of the frame 1 relative to the ground during operation. And a driving sprocket 23 is arranged on the ground wheel shaft 22 of the ground wheel 2. The seed fertilizer box 3 is located above the frame 1, and is divided into two front and rear areas by a partition inside, one area for seeds and one area for fertilizers. A seed / fertilizer wheel 31 is arranged below the seed fertilizer box 3, and the number of the seed / fertilizer wheels 31 is determined according to the number of rows required for sowing and fertilizing. The seed / fertilizer wheels 31 are connected in series through a seed fertilizer box shaft 32, and at least one end of the seed fertilizer box shaft 32 is provided with a driven sprocket 33. The two areas of the seed fertilizer box 3 each have a set of the seed fertilizer box shaft 32 and the driven sprocket 33. The transmission mechanism 4 is a transmission group composed of gears and sprockets arranged on both sides of the seed fertilizer box 3, which can change the transmission direction and transmission ratio. It rotates the driving sprocket 23 on the ground wheel 2 and the driven sprocket 33 on the seed fertilizer box 3 through chains, respectively, to transmit the driving force of the ground wheel 2 to the seeding / fertilizer wheel 31. During operation, the ground wheel 2 is pressed on the ground. As the tractor pulls the seeder forward, the ground wheel 2 rotates under the action of the ground friction force, and the driving sprocket 23 drives the transmission mechanism 4. The transmission mechanism 4 drives the driven sprocket 33 to rotate, and the seed fertilizer box shaft 32 where the driven sprocket 33 is located rotates, and then drives the seeding / fertilizer wheel 31 to rotate, so that the seeds and fertilizers in the seed fertilizer box 3 are introduced into the fertilizer / seed disc device 5 below, and then enter the soil. The fertilizing / seeding disc device 5 is composed of a traction frame 51, a spring 52, a disc 53, and a depth limiting ring 54. The depth limiting ring 54 is cylindrical and fixed on the disc 53, and is concentric with the disc 53, and its diameter is smaller than the disc 53. During operation, the traction frame 51 is fixed on the frame 1, and the disc 53 is rotatably connected to the traction frame 51. The traction frame 51 can be pressed downward under the action of the spring 52 so that the disc 53 can cut into the soil downward. Since the depth limiting ring 54 is cylindrical, it cannot cut into the soil, thereby limiting the cutting depth of the disc 53, thereby controlling the depth of fertilizing / seeding. The fertilizing / seeding discs 5 are arranged according to agronomic needs, and can be arranged in a front-to-back staggered manner, and at least two groups, one for fertilizing and one for sowing. The drip irrigation device 6 is composed of a drip irrigation frame 61 and a tape laying device 62. The drip irrigation frame 61 is fixed above the frame 1 and is used to support the drip irrigation tape roll. The tape laying device 62 is fixed below the frame 2. The drip irrigation tape passes through the tape laying device 62 and is laid on the ground. The number of the drip irrigation devices 6 can be increased or decreased according to agronomic needs.The pressing roller 7 is cylindrical and rotatably connected to the bottom of the frame 2. Its length is adapted to the seeding / fertilizing area of ​​the fertilizing / seeding disc device 5 and it is located behind the fertilizing / seeding disc device 5. Its function is to compact the loose soil so that the seeds and the soil fit more closely. The row brush 8 is movably connected to the back of the pressing roller 7 and its lateral length is adapted to the pressing roller 7. When working, the compression spring 82 provides downward pressure, and the brush part below the row brush 8 is close to the ground, smoothing the soil and smoothing some of the grooves opened by the fertilizing / seeding disc device 5, and covering some of the exposed seeds with soil.

[0026] Preferably, the stripes on the seeding / fertilizer wheel 31 are in a "human" shape, which guides from the middle to both sides. When working, compared with ordinary seeding / fertilizer wheels with horizontal stripes, it can always maintain a certain seeding / fertilizer space for taking seeds and fertilizers. Compared with seeding / fertilizer wheels with oblique stripes in a single direction, the "human" shape guides seeds / fertilizers to both sides, which is more uniform in the horizontal direction.

[0027] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
