Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, in particular to a device for synchronously conveying fertilizer stirring and seeds in proportion. Background Art

[0002] The distance between seeds and fertilizers is referred to as "seed-fertilizer spacing". That is, when sowing mechanically, seeds and fertilizers need an appropriate seed-fertilizer spacing to ensure that the seeds germinate safely and promote the nutrient needs of the seedlings to grow healthily. If the seed-fertilizer spacing is too small, the seeds and fertilizers may come into direct contact, which will affect seed germination or cause seedling burn and root rot; if the seed-fertilizer spacing is too large, the utilization rate of the fertilizer will be reduced. In dryland or unsaturated irrigation areas, in order to improve fertilizer utilization efficiency and reduce the number of operations, especially under protective farming conditions, the method of synchronous sowing and fertilization is generally adopted during sowing. Different crops, different terrains, and different soil conditions may have different requirements for the seed-fertilizer spacing, so it is necessary to frequently adjust the dropping position of fertilizers and seeds in the conveying device. The dropping positions of fertilizers and seeds in the existing synchronous conveying devices need to be adjusted separately, which is cumbersome to operate and inefficient. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-7 , the present invention provides a fertilizer mixing and seed proportion synchronous conveying device, comprising a feeding mechanism mounted on a frame for containing seeds and fertilizers respectively, a seed conveying mechanism for conveying seeds from the feeding mechanism to a field, a fertilizer conveying mechanism for conveying fertilizers from the feeding mechanism to a field, and a power mechanism for providing power;

[0033] The seed conveying mechanism comprises a seed conveying support component 11 mounted on the frame at the bottom and a seed conveying auger that penetrates the whole body, wherein the seed conveying support component 11 is used to support the seed conveying auger, and a seed conveying inlet is provided at the upper part of one end of the seed conveying auger, and a seed discharge port 14 is provided at the lower part of the other end;

[0034] The fertilizer conveying mechanism comprises a fertilizer conveying support component 15 whose bottom is mounted on the frame and a fertilizer conveying auger 16 which runs through the whole body. The fertilizer conveying support component 15 is used to support the seed conveying auger. A fertilizer conveying inlet 17 is provided at the upper part of one end of the fertilizer conveying auger 16, and a fertilizer discharge port 18 is provided at the lower part of the other end.

[0035] The seed conveying support component 11 and the fertilizer conveying support component 15 are both rotatably mounted on the same rotating disk 19, and the rotating disk 19 is rotatably mounted on the frame. The rotating disk 19 is externally connected to a driving power supply, and a direction adjustment component for simultaneously adjusting the rotation of the seed conveying support component 11 and the fertilizer conveying support component 15 is provided on the rotating disk 19.

[0036] like Figure 1 , Figure 3As shown, the working process of the present invention is that the feeding mechanism for holding seeds and fertilizers respectively puts the seeds to be planted and the mixed fertilizers into the seed delivery entrance and the fertilizer delivery entrance 17. The seeds and fertilizers are respectively delivered to the seed discharge port 14 and the fertilizer discharge port 18 by the seed delivery auger and the fertilizer delivery auger 16, and fall onto the reclaimed land. When the seed-fertilizer spacing needs to be adjusted according to actual conditions, the present invention drives the seed delivery support component 11 and the fertilizer delivery support component 15 to rotate simultaneously through the adjustment component, so as to adjust the drop spacing between the fertilizer and the seeds, avoid separate adjustment, and improve work efficiency; the present invention can also rotate the entire rotating disk 19 through an external power supply, adjust the direction of the entire seed delivery auger and the fertilizer delivery auger 16, and control the drop orientation of the fertilizer and seeds relative to the frame, so that the device can expand the working range and improve applicability when it is inconvenient to move in the terrain.

[0037] As a further solution of the present invention, the direction adjustment component includes a first rotating shaft 21 and a second rotating shaft 22 rotatably mounted on the rotating disk 19, the seed conveying support component 11 and the fertilizer conveying support component 15 are rotatably mounted on the rotating disk 19 through the first rotating shaft 21 and the second rotating shaft 22 respectively, a first gear 23 is fixedly mounted on the first rotating shaft 21, and a second gear 24 is fixedly mounted on the second rotating shaft 22, the first gear 23 and the second gear 24 are both transmission-connected with a driving rack 25 slidably mounted on the rotating disk 19, the driving rack 25 is slidably mounted along the radial direction of the rotating disk 19, the first gear 23 and the second gear 24 are respectively arranged on both sides of the driving rack 25, the driving rack 25 is connected to a driving motor 26 arranged on the rotating disk 19, and the driving motor 26 is used to drive the driving rack 25 to slide.

[0038] The specific adjustment process of the steering component is as follows: Figure 3 , Figure 4As shown, when the distance between the seed and fertilizer needs to be increased, the driving rack 25 is driven by the electric saw to slide radially on the rotating disk 19. Because the driving rack 25 is connected to the first gear 23 and the second gear 24 on both sides thereof, the first gear 23 and the second gear 24 are synchronously driven to rotate in the opposite direction when the driving rack 25 slides. The first gear 23 and the second gear 24 drive the first rotating shaft 21 and the second rotating shaft 22 to rotate in the opposite direction. The first gear 23 is fixedly connected to the seed conveying support component 11, and the second gear 24 is fixedly connected to the fertilizer conveying support component 15. Therefore, the seed conveying support component 11 and the fertilizer conveying support component 15 rotate in the opposite direction by an angle, and the angle between the two increases. Therefore, the distance between the seed discharge port 14 and the fertilizer discharge port 18 on the seed conveying auger and the fertilizer conveying auger 16 increases, and the distance between the seed and fertilizer formed after the material is dropped increases. Conversely, when the distance between the seed and fertilizer needs to be reduced, the motor can be driven to rotate in the opposite direction.

[0039] As a further solution of the present invention, the driving motor 26 is installed on a sliding seat 31, and the sliding seat 31 is slidably installed on the rotating disk 19, and the sliding direction of the sliding seat 31 is parallel to the sliding direction of the driving rack 25; along the sliding direction of the sliding seat 31, a first spring 32 is arranged between the sliding seat 31 and the rotating disk 19; the driving motor 26 is meshed with the driving rack 25 through a driving gear 27; a round head driving part 33 is fixedly arranged at one end of the sliding seat 31 away from the axis of the rotating disk 19, and the round head driving part 33 is slidably connected to an arc-shaped limiting track 34 fixedly installed on the frame, and when the round head driving part 33 slides on the arc-shaped limiting track 34, it drives the sliding seat 31 to slide on the rotating disk 19.

[0040] When the orientation of the entire seed conveying auger and the fertilizer conveying auger 16 is adjusted by rotating the rotating disk 19 to control the dropping orientation of the fertilizer and seeds relative to the frame, the final seed-fertilizer spacing will also change accordingly. Figure 7 As shown in the figure, a is the spacing between the seed and fertilizer before rotation, and b is the spacing between the seed and fertilizer after rotation. Through simple mathematical knowledge, we can know that the right angle side of a triangle is smaller than the hypotenuse, a>b, so the spacing between the seed and fertilizer changes after rotation. It is necessary to increase the angle between the original seed conveying auger and the fertilizer conveying auger 16 appropriately to maintain the original spacing between the seed and fertilizer. Figure 4As shown, when the rotating disk 19 rotates, the sliding seat 31 installed thereon is driven to rotate together, and the rotation of the sliding seat 31 drives the round head driving part 33 thereon to slide on the arc-shaped limit track 34. The arc-shaped limit track 34 is fixedly mounted on the frame. When the round head driving part 33 slides on the arc-shaped limit track 34, the sliding seat 31 is driven radially inward along the rotating disk 19. Because the driving motor 26 is installed on the sliding seat 31, the driving motor 26 is meshed with the driving rack 25 through the driving gear 27. Therefore, when the sliding seat 31 slides, the driving motor 26, the driving gear 27 and the driving rack 25 slide accordingly. The sliding of the driving rack 25 drives the first gear 23 and the second gear 24 to rotate, slightly increasing the angle between the seed conveying auger and the fertilizer conveying auger 16. It should be noted that the function of the arc-shaped limit track 34 of the present invention is to drive the seed conveying auger and the fertilizer conveying auger 16 to rotate when the rotating disk 19 rotates, thereby increasing the angle and roughly compensating for the change in the spacing between the seed and fertilizer. If specific and precise control is required, it is still necessary to control the sliding of the drive rack 25 by the drive motor 26 to achieve it.

[0041] like Figure 5 , Figure 6 As shown, as a further solution of the present invention, the seed discharge port 14 and the fertilizer discharge port 18 are both provided with limit assemblies for controlling the discharge direction; the limit assemblies include limit rings 41 rotatably mounted on the seed conveying auger and the fertilizer conveying auger 16 respectively, the limit ring 41 is provided with an opening 42, and limit clamps 43 are fixedly arranged on both sides of the opening 42, and seeds and fertilizers leave the seed conveying auger and the fertilizer conveying auger 16 through the opening 42 between the limit clamps 43; a windward plate 44 is fixedly installed on the side of the limit ring 41 away from the opening 42; a second spring 45 is arranged between the limit clamp 43 and the seed conveying auger and the fertilizer conveying auger 16.

[0042] like Figure 5 As shown, the seed outlet 14 and fertilizer outlet 18 of the present invention are both raised to facilitate the dropping of seeds. However, when the external environment changes, such as when the wind force changes, the dropping position of seeds and fertilizers may change under the action of wind force. Moreover, because the mass and volume of the dropped seeds and fertilizers are different, the change range of their drop points is also different, which in turn affects the final spacing between seeds and fertilizers after dropping. Therefore, Figure 5 , Figure 6As shown, the present invention is provided with a limit ring 41 rotatably mounted on the seed conveying auger and the fertilizer conveying auger 16 at the seed discharge port 14 and the fertilizer discharge port 18, and the seeds and fertilizers leave the seed conveying auger and the fertilizer conveying auger 16 through the opening 42 between the limit clamps 43. A windward plate 44 is installed on the opposite side of the opening 42 of the limit ring 41. When the lateral wind comes, the wind blows on the windward plate 44, and the windward plate 44 drives the limit ring 41 to deflect slightly to one side under the action of the wind. At this time, the opening 42 located below it will deflect to the other side, slightly changing the discharge direction, so that it can compensate for the distance change caused by the wind when the material falls. The second spring 45 in the present invention is to facilitate the reset of the limit ring 41 and prevent the limit ring 41 from rotating completely under the action of the wind. The same is true in reverse. And the deflection angle of the limit ring 41 of the present invention will change with the change of wind force, and the direction and angle of the discharge will be changed in real time.

[0043] like Figure 1 , Figure 2 As shown, as a further solution of the present invention, the feeding mechanism includes a seed lifting component, a seed material box 61, a fertilizer lifting component, and a stirring tank 62; the seed material box 61 is arranged between the seed lifting component and the seed conveying inlet; the stirring tank 62 is arranged between the fertilizer lifting component and the fertilizer conveying inlet 17.

[0044] like Figure 2 As shown, as a further solution of the present invention, the seed lifting component includes a seed lifting inlet 51 installed at the bottom, a seed lifting auger 52 and a seed lifting hydraulic motor 53 installed coaxially therewith at the top, and a seed feeding port 54 is opened on one side of the upper part of the seed lifting component.

[0045] like Figure 2 As shown, as a further solution of the present invention, the fertilizer lifting component includes a fertilizer lifting inlet 55 installed at the bottom, a fertilizer lifting auger 56 and a fertilizer lifting hydraulic motor 57 installed coaxially therewith at the top, and a fertilizer feeding port 58 is opened on one side of the upper part of the fertilizer lifting component.

[0046] As a further solution of the present invention, a hydraulic control box is arranged on the frame, and the hydraulic control box is used to control the rotation speed of the seed conveying auger and the fertilizer conveying auger 16.

[0047] Before the sowing and fertilizing machine works, it is generally necessary to mix the compound fertilizer and chemical fertilizer manually or with a special mixing machine to achieve uniformity, and then pour them into the fertilizer box of the sowing and fertilizing machine manually. In addition, the seeds also need to be poured manually, with a low degree of mechanization and high labor intensity. Moreover, when the sowing and fertilizing machine is working, due to the inconsistent volume of seeds and fertilizers, there will be leftover seeds or fertilizers, and the box needs to be refilled. The remaining amount affects the operation efficiency. After searching, the existing plant protection machinery and auxiliary equipment only have a separate mixing function or conveying function to replace manual operations. There is no equipment to realize the synchronous and proportional delivery of seeds and fertilizers. There is no corresponding sowing and fertilizing machinery in the operation link. The fertilizer mixing and the intermediate delivery of seeds and fertilizers take a long time, and the volume of each material box cannot be fully utilized.

[0048] An embodiment of the present invention provides a technical solution for mixing fertilizer and synchronously conveying fertilizer seeds in volume ratio. Seeds and fertilizers are conveyed to the fertilizer mixing box and the seed material box 61 by using a seed lifting component and a fertilizer lifting component. The fertilizer is uniformly composed under the rotation of the stirring tank 62. Finally, the fertilizer conveying mechanism and the seed conveying mechanism are connected to the feed port of the sowing and fertilizing machine. The hydraulic flow of the hydraulic control box is adjusted to control the rotation speed of the seed conveying auger and the fertilizer conveying auger 16, so as to realize the proportional adjustment of seeds and fertilizers, save labor, and improve work efficiency. The embodiment provided by the present invention can realize the function of uniformly stirring fertilizers. The fertilizer can be automatically output to the fertilizer box of the seeding and fertilizing machine by relying on the fertilizer conveying auger 16 and the fertilizer conveying support component 15. The seeds and fertilizers can be synchronously conveyed to the seed box of the seeding and fertilizing machine in proportion through the hydraulic transmission and control principles. The seeds and fertilizers can be conveyed in different volume ratios through the speed adjustment of each hydraulic motor, which is beneficial to the precise proportional application of seeds and fertilizers. At the same time, the idle space of the seed or fertilizer box is reduced, which saves time and labor during operation, significantly reduces the labor intensity, and is suitable for large-scale field operations.

[0049] As a further solution of the present invention, a ground wheel 63 is arranged at the bottom of the frame. The purpose of this arrangement is to facilitate the movement of the present invention and expand the working range.

[0050] As a further solution of the present invention, the seed conveying support component 11 and the fertilizer conveying support component 15 adopt telescopic hydraulic support. The height of the seed discharge port 14 and the fertilizer discharge port 18 can be adjusted by the telescopic hydraulic support so that they can be applied to soils of different terrains and improve their applicability.
