Description

Technical Field

[0001] The present application relates to the field of intelligent agricultural technology, and in particular, to a spreading device. Background Art

[0002] In the process of modern agricultural technology innovation, the spreader, as a key equipment widely used in agricultural operations such as sowing and fertilization, plays an important role. In the design of related technologies, the auger of the spreader usually adopts a horizontal layout, so that the material is transmitted horizontally to the material spreading bin and falls from the material spreading bin to complete the spreading operation. However, due to the structural characteristics of the horizontal auger, when the material enters the material spreading bin, it often produces a large scattering phenomenon due to the rotation of the auger, and then deviates from the expected spreading area, resulting in uneven material spreading and affecting the spreading effect.

[0003] In view of this, proposing a spreader that can reduce material scattering and improve spreading uniformity has become an urgent problem to be solved. Summary of the invention

[0004] The present application provides a spreading device that can drain and gather materials transmitted from an auger, reduce scattering of the materials due to the rotation of the auger, and improve the uniformity of material spreading.

[0005] In a first aspect, a spreading device is provided, which includes an inlet, an auger, a material spreading bin, a discharge port and a material concentrating device, wherein the material concentrating device includes: a guide device, which is arranged at the discharge port of the auger, and is used to guide the material transmitted from the auger to the material spreading bin at the discharge port, so that the material gathers and falls on the guide device; and / or, a gathering device, which is arranged at the lower edge of the material spreading bin, and is used to gather the material falling from the material spreading bin again, so that the material falls into the central area of ​​the spreading disk arranged in the discharge port.

[0006] In the above-mentioned spreading device, by setting a flow guide device at the auger outlet, the material transmitted from the auger to the material spreading bin can be effectively guided, reducing the scattering of the material due to the force of the auger rotation and the decrease in its own weight, so that the material flows down in the direction guided by the flow guide device; the gathering device can be closely connected to the bottom of the material spreading bin, and can secondary gather some of the scattered materials that still exist in the process of the material falling from the spreading bin, effectively limiting the falling range of the material, so that the material falls into the center of the spreading disc. By setting the flow guide device and the gathering device, the falling path of the material can be guided, so that the material falls into the center area of ​​the spreading disc, and then with the help of the rotation of the spreading disc, the material can be evenly spread in the predetermined spreading area, thereby improving the uniformity of material spreading.

[0007] In combination with the first aspect, in some implementations of the first aspect, the guide device includes a guide plate, and the guide plate is arranged along the edge circumference of the discharge port of the auger.

[0008] In the above implementation, the guide plate is designed along the circumference of the edge of the discharge port, so that the material that originally falls according to its own weight can be gathered into a flow on the guide plate and fall along the guiding direction of the guide plate.

[0009] In some implementations, the outer edge of the guide plate is lower than the inner edge connected to the auger.

[0010] In the above implementation, there is a certain downward tilt angle between the guide plate and the auger, which can more effectively guide the material on the guide plate to flow to the low point along the tilt direction under the action of gravity.

[0011] In some implementations, the length of the guide plate is greater than or equal to one-quarter of the circumference of the auger.

[0012] In the above implementation, when the length of the guide plate is greater than or equal to one-quarter of the circumference of the auger, the guide plate can have a sufficient contact area to receive and gather the materials.

[0013] In some implementations, a chamfer is provided from the lowest point of the guide plate to the end of the guide plate.

[0014] In the above implementation, the beveled surface can provide a flow outlet for the guide plate, so that the material collected at the low point of the guide plate flows down at the beveled surface, thereby guiding the falling direction of the material.

[0015] In some implementations, the guide device further includes a baffle assembly, which is used to prevent the material from rushing out of the guide plate.

[0016] In the above implementation, the baffle assembly can reduce the impact of materials caused by a large flow rate, so that the materials flow and converge in the direction set by the guide device.

[0017] In some implementations, the baffle assembly includes side baffles and a top baffle.

[0018] In some examples, the side baffle is disposed on a side of the guide plate away from the auger, and the top baffle is disposed at a beginning of the guide plate.

[0019] In the above implementation, the side baffles can prevent materials from rushing out of the guide plate directly due to centrifugal force, and the top baffle can prevent excessive materials on the guide plate from overflowing directly from the top of the guide plate.

[0020] In some implementations, the bottom diameter of the gathering device is smaller than the top, and has a funnel-shaped structure that shrinks from top to bottom.

[0021] In the above implementation, the smaller bottom diameter limits the diffusion range of the material, so that the fallen material can be further concentrated and landed in the central area of ​​the spreading plate of the discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] The present application provides a spreading device, which can reduce scattering during material transmission and spreading and improve spreading uniformity.

[0031] With the rapid development of science and technology, modern agricultural technology is constantly innovating, and the application of various mechanized equipment has become an important means to improve agricultural production efficiency. Among them, the spreader, as a key equipment, is widely used in agricultural operations such as sowing and fertilizing. In related technologies, the spreader usually places the auger structure horizontally, so that the material is transported to the sowing bin through the lateral transmission of the auger, and then the rotating sowing disc at the bottom of the sowing bin throws the material out and spreads it to the target area. However, this design has certain limitations and defects, that is, due to the scattering phenomenon when the material falls, it may cause uneven material sowing, resulting in reduced sowing accuracy.

[0032] The technical solution in the present application will be described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0033] Figure 1 It is a schematic diagram of a spreading device provided in an embodiment of the present application.

[0034] Figure 1 It is a schematic diagram of a spreading device 100 provided in an embodiment of the present application. The spreading device 100 mainly includes a material inlet 110 , an auger assembly 120 , a material spreading bin 130 and a material outlet 140 .

[0035] When the sowing device 100 is in operation, seeds or other granular materials are first put into the device through the feed port 110. The feed port 110 is wide at the top and narrow at the bottom to ensure that the material can smoothly enter the auger assembly 120. The auger assembly 120 is the transmission mechanism of the sowing device 100, and the material is transported from the feed port 110 along the auger to the material sowing bin 130 through the rotation of the spiral blade. After the material enters the material sowing bin 130, it naturally falls into the discharge port 140 due to gravity. A sowing disc is provided at the bottom of the discharge port 140, and the sowing disc can rotate to throw the material into the sowing area to achieve sowing.

[0036] When the above-mentioned spreading device is working, the material may have a tendency to move in different directions due to the influence of the rotation of the auger when the material is transmitted to the material spreading bin 130 through the auger assembly 120. In the absence of effective guidance and restriction, the material may be scattered at a large angle and deviate from the expected spreading path, resulting in part of the material failing to accurately land on the target area of ​​the spreading plate, causing uneven spreading of the material during the rotating spreading process of the spreading plate, affecting the spreading effect.

[0037] In response to the above problems, the embodiment of the present application provides a material concentration device 200 disposed in a spreading device, which is intended to improve the spreading uniformity of the spreader, especially for the transportation of small and medium-sized material flows, and can optimize the movement trajectory of the material in the process of falling from the spreading bin to the spreading plate, and reduce the occurrence of material scattering. The device 200 includes two key structures: a guide device 210 and a gathering device 220. The main function of the guide device 210 is to guide the movement direction of the material before the material falls, so that the material can fall along a predetermined direction, thereby effectively reducing the scattering of the material during the falling process; the gathering device 220 can gather the material after it falls again, and guide the material to fall in the spreading plate. Since the landing position of the material is relatively concentrated, the material will be spread more evenly after being thrown out by the rotation of the spreading plate.

[0038] For the device 200, specifically Figures 2 to 4 As shown. Figure 2 The figure is a cross-sectional schematic diagram of a spreader provided with a material concentration device 200 including a guide device 210 and a gathering device 220 according to an embodiment of the present application.

[0039] In some embodiments, the guide device 210 is disposed on the discharge port side of the auger assembly 120 , at the connection with the material spreading bin 130 .

[0040] In this case, the guide device 210 can effectively guide the material flowing out of the auger assembly 120 to fall steadily in a predetermined direction. By reducing the scattering of the material, the guide device 210 can reduce the uneven distribution of the material on the spreading disc due to scattering, thereby reducing the uneven spreading.

[0041] In some embodiments, the gathering device 220 is disposed at the bottom of the material spreading bin 130 , within the discharge port 140 .

[0042] In this case, after the material falls through the guide device 210, the gathering device 220 can further concentrate the partially scattered material to the central area of ​​the spreading plate, so that the material can be more evenly distributed when thrown out by the spreading plate, thereby improving the uniformity and efficiency of spreading.

[0043] Figure 3 A schematic diagram of a flow guide device provided in an embodiment of the present application.

[0044] In some embodiments, the guide device 210 includes a guide plate 211 , and the guide plate 211 is arranged along the edge circumference of the discharge port of the auger assembly 120 .

[0045] In some examples, the auger assembly 120 is composed of an auger housing 121 and an internal auger 122. The auger housing 121 is cylindrical and forms a cavity. The auger 122 is arranged in the cavity to rotate to achieve material transfer and transportation. In this case, the guide plate 211 is arranged along the edge circumference of the connection between the auger housing 121 and the material spreading bin 130.

[0046] In these examples, especially for small and medium flow material sowing scenarios, the design of the guide plate 211 can effectively change the falling trajectory of the material. After the material is transmitted to the material sowing bin 130 through the auger assembly 120, the material that originally fell naturally due to its own weight will be gathered into a flow under the guidance of the guide plate 211, and fall along the guiding direction of the guide plate, reducing the scattering caused by the direct fall of the material.

[0047] In some embodiments, the outer edge of the guide plate 211 is lower than the inner edge, the inner edge is the side where the guide plate 211 is connected to the auger housing 121, and the outer edge is the side where the guide plate 211 is away from the auger housing, that is, the guide plate 211 has a certain downward inclination angle relative to the auger housing 121.

[0048] In the above embodiment, the downward inclination angle of the guide plate 211 can guide the material on the guide plate 211 to flow naturally to the low point. Specifically, the material is affected by gravity on the surface of the guide plate 211, flows along the inclination direction, and finally gathers at the low point of the guide plate and falls.

[0049] In some examples, the length of the guide plate 211 is greater than or equal to one quarter of the circumference of the auger housing 121 .

[0050] In the above example, by designing the length of the guide plate 211 to be greater than or equal to one quarter of the circumference of the auger housing 121, the guide plate 211 can have a sufficient contact area when guiding the material, thereby achieving the function of receiving and gathering the material.

[0051] In some examples, the starting end of the guide plate 211 is set between the twelve o'clock direction and the three o'clock direction of the circumference of the auger housing 121, and the end of the guide plate 211 is set between the six o'clock direction and the nine o'clock direction of the circumference of the auger housing 121. The starting end of the guide plate 211 refers to that the guide plate 211 is set at the higher end of the auger housing, and the end of the guide plate 211 refers to that the guide plate 211 is set at the lower end of the auger housing.

[0052] It should be understood that the above-mentioned “starting point” and “end point” are only for the convenience of description and do not constitute limitations.

[0053] In the above example, by limiting the start and end positions, the length of the guide plate can effectively receive and gather most of the materials transmitted from the auger assembly 120, preparing for the diversion of the materials in the falling direction.

[0054] In some examples, a chamfered surface 2111 is provided at a lower end of the guide plate 211 , extending from the lowest point to the end.

[0055] In the above embodiment, the material flowing into the guide plate 211 can gather to the lowest point under the action of gravity, and the beveled surface 2111 is used as the outlet of the guide plate, so that the material gathered at the low point of the guide plate 211 flows down at the beveled surface 2111, thereby guiding the falling direction of the material on the guide plate 211.

[0056] In some embodiments, the flow guiding device 210 further includes a baffle assembly, which may include a side baffle 212 and a top baffle 213 .

[0057] In the above embodiment, the baffle assembly can block the material entering the guide device 210 , reduce the impact caused by the large material flow rate, and force the material to flow and converge along the low point direction of the guide device 210 .

[0058] In some examples, the side baffle 212 is disposed on a side of the guide plate 211 away from the auger assembly.

[0059] In these cases, the side baffle 212 forms a boundary for the material to flow on the guide plate 211 , controls the flow direction of the material, and prevents the material entering the guide plate 211 from directly rushing out of the guide plate due to excessive centrifugal force, thereby affecting the guide effect of the guide plate 211 .

[0060] In some examples, the top baffle 213 is disposed at the beginning of the guide plate 211 .

[0061] In these cases, the top baffle 213 serves to limit the material, thereby preventing the material from directly overflowing from the top of the guide plate 211 due to excessive accumulation, thereby affecting the guiding function of the guide plate 211 .

[0062] In some embodiments, the flow guide device 210 and the auger assembly 120 may be integrally formed, or fixed to the auger assembly 120 by means of screws, snaps, or welding.

[0063] In these cases, the appropriate fixing method can be selected according to the requirements of the usage scenario.

[0064] Figure 4 A schematic diagram of a gathering device provided in an embodiment of the present application.

[0065] In some embodiments, the top and bottom of the gathering device 220 are open, and the structural design presents a hollow funnel shape that gradually shrinks from top to bottom.

[0066] In some examples, the top of the gathering device 220 is connected to the bottom of the material spreading bin 130, and the circumference of the top is consistent with the circumference of the bottom of the material spreading bin 130, forming a tight connection structure.

[0067] This design enables the gathering device to work closely with the bottom outlet of the material spreading bin, ensuring that the material flows out smoothly and is guided along the predetermined path, avoiding excessive dispersion or deviation from the target area during the falling process, thereby ensuring that the material can flow stably along the collection area of ​​the device. The smaller diameter of the lower part limits the diffusion range of the material, allowing it to be concentrated and evenly landed in the designated area, further improving the material spreading effect and accuracy.

[0068] Since the gathering device 220 presents a funnel-shaped structure that contracts from top to bottom, it can be known that the angle between the inner wall extension line of the material spreading bin 130 and the gathering device 220 is an acute angle.

[0069] In some examples, the included angle between the inner wall extension line of the material spreading bin 130 and the gathering device 220 is an acute angle ranging from 5° to 60°.

[0070] Such an angle design can optimize the guiding effect of the material flow, allowing the material to flow smoothly down along the inner wall of the gathering device 220 to achieve a gathering effect, while avoiding poor falling due to a too large angle.

[0071] In some embodiments, when the shape of the material spreading bin 130 is not cylindrical, the design shape of the gathering device 220 can be adjusted accordingly according to the specific shape of the material spreading bin 130 .

[0072] For example, if the material spreading bin 130 is a rectangular cylindrical structure, the upper and lower shapes of the gathering device 220 will also be designed to be rectangular structures accordingly, and the rectangular opening of the lower part is smaller than the rectangular opening of the upper part.

[0073] Such a design can ensure that the shape of the gathering device 220 can be consistent with the shape of the sowing bin 130, so that the gathering device 220 and the sowing bin 130 are always tightly connected, so that the material falling from the material sowing bin 130 can be effectively gathered and fall into the central area of ​​the sowing plate at the bottom of the discharge port 140.
