Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an agricultural machinery fertilization device. Background Technology

[0002] Agricultural fertilization is a key guarantee for crop growth and agricultural production. Soil natural nutrients are limited and cannot meet the needs of crops for key elements such as nitrogen, phosphorus, and potassium. Fertilization can precisely supplement these nutrients, supporting photosynthesis, root development, and flower and fruit formation. At the same time, reasonable fertilization can maintain soil fertility, prevent degradation due to continuous cropping, and significantly improve crop yield and quality, such as increasing grain plumpness and fruit sugar content. It is an important measure to ensure stable agricultural output.

[0003] For some agricultural crops, due to the influence of the crop's growth environment and characteristics, it is difficult to fertilize the crops using large machinery. As a result, fertilization is generally carried out manually, which makes it difficult to ensure the uniformity of fertilizer application and may lead to fertilizer waste or loss. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an agricultural machinery fertilization device to solve the problem that it is difficult to ensure uniform fertilization during the fertilization process in the prior art.

[0005] This invention is achieved through the following technical solution: An agricultural machinery fertilization device includes a frame structure, an adjustment structure installed inside the frame structure, front wheels installed on both sides of the adjustment structure, a fertilizer hopper installed on the frame structure, a metering structure installed on the other side of the frame structure, and symmetrically distributed rear wheels installed on the metering structure. The frame structure is equipped with a discharge structure, which includes a limiting sliding frame symmetrically distributed on the frame structure. A sliding discharge baffle is slidably connected inside the limiting sliding frame. A discharge trough is opened on the sliding discharge baffle. A sluice with the same size as the discharge trough is opened at the bottom of the fertilizer hopper. The quantitative structure includes a protective shell mounted on a frame structure, a quantitative scraper installed inside the protective shell, a feed plate installed on the quantitative scraper, and a fixed height between the bottom surface of the quantitative scraper and the ground.

[0006] Preferably, the frame structure includes a front stabilizer, a fixed bracket is mounted on the front stabilizer, a pull rod is rotatably connected to the fixed bracket, a symmetrically distributed rear stabilizer is slidably connected to the front stabilizer, a return spring is respectively provided between the front stabilizer and the rear stabilizer, and the protective shell is mounted on the rear stabilizer.

[0007] Preferably, the control structure includes symmetrically distributed rotating shafts installed in the front stabilizer, an control rod installed between the rotating shafts, a limit bracket installed on the lower side of the front stabilizer, symmetrically distributed sliding blocks slidably connected through the limit bracket, the sliding blocks being slidably connected to the control rods, and a transmission block installed on the sliding blocks.

[0008] Preferably, the front stabilizer is equipped with a transmission assembly corresponding to the rotating shaft. The transmission assembly includes connecting blocks symmetrically distributed on the front stabilizer. A rotating rod is rotatably connected through the connecting blocks. A drive crank and a driven crank are mounted on the rotating rod. A sliding rod is slidably connected inside the driven crank.

[0009] Preferably, the transmission crank is rotatably connected to the transmission block, the sliding discharge baffle is equipped with symmetrically distributed transmission rods, the transmission rods are rotatably connected to the sliding rods, the distance between the rotating rod and the transmission crank is the same as the horizontal distance of the groove opened on the sliding block, and the rotating shaft rotates synchronously with the front wheel.

[0010] Preferably, an isolation shell is installed inside the protective shell, the isolation shell is fixedly installed with the metering scraper and the feed plate, and a guide block is installed inside the metering scraper.

[0011] Preferably, the isolation shell is equipped with a waste material handling chute, which is slidably connected to the fertilizer hopper, and a transport scraper is installed inside the isolation shell.

[0012] Preferably, the rotating shaft of the transport scraper rotates synchronously with the rear wheel, and the transport scraper is equipped with an array of scrapers, the scrapers of the transport scraper are in frictional engagement with the metering scraper and the bottom of the isolation shell.

[0013] This agricultural machinery fertilization device, through the linkage of the front wheel and the discharge structure, intermittently conveys fertilizer from the fertilizer hopper into the fertilization trench as the front wheel rotates. A metering scraper then levels the fertilizer in the trench, and excess fertilizer flows through the inclined surface of the scraper into an isolation housing. The rotation of the rear wheel causes the fertilizer in the isolation housing to be transported by a transport scraper to a waste material treatment chute, and then back into the fertilizer hopper, ensuring full utilization of the fertilizer. Furthermore, to address potential unevenness in the fertilization trench, the relative sliding between the front and rear stabilizing frames ensures that the up-and-down sliding of the front wheel during rotation does not affect the stability of the rear wheel. This, in turn, ensures that the distance between the bottom surface of the metering scraper and the bottom surface of the fertilization trench remains consistent, guaranteeing a consistent fertilizer application rate.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0022] Please see Figures 1 to 9 The present invention provides a technical solution: an agricultural machinery fertilization device. It includes a frame structure 1, an adjustment structure 5 installed inside the frame structure 1, front wheels 2 installed on both sides of the adjustment structure 5, a fertilizer hopper 3 installed on the frame structure 1, a metering structure 7 installed on the other side of the frame structure 1, and symmetrically distributed rear wheels 6 installed on the metering structure 7. Among them, a discharge structure 4 is installed on the frame structure 1. The discharge structure 4 includes a limiting sliding frame 41 symmetrically distributed on the frame structure 1. A sliding discharge baffle 42 is slidably connected inside the limiting sliding frame 41. A discharge groove 44 is opened on the sliding discharge baffle 42. A trough with the same size as the discharge groove 44 is opened at the bottom of the fertilizer hopper 3. The quantitative structure 7 includes a protective shell 71 installed on the frame structure 1, a quantitative scraper 72 installed inside the protective shell 71, a feed plate 73 installed on the quantitative scraper 72, and the height between the bottom surface of the quantitative scraper 72 and the ground is fixed.

[0023] Using the above method: In some agricultural planting environments where the height of agricultural machinery is limited, the operator puts fertilizer into the fertilizer hopper 3, and then the frame structure 1 pulls the device to move along the fertilizer trenches dug on both sides of the crops. Through the rotation of the front wheel 2, the sliding discharge baffle 42 is slid back and forth through the control structure 5. Then, the trough at the bottom of the fertilizer hopper 3 and the discharge chute 44 opened on the sliding discharge baffle 42 are connected, so that the fertilizer in the fertilizer hopper 3 leaks downward through the discharge chute 44. The operator pulls the device forward, so that the fertilizer in the fertilizer hopper 3 is intermittently transported into the fertilizer trench.

[0024] On the other hand, as the device moves forward, the metering structure 7 moves forward synchronously, and the metering scraper 72 flattens the fertilizer that falls into the fertilization ditch. By limiting the distance between the bottom of the front wheel 2 and the ground of the fertilization ditch, the amount of fertilizer remaining after the metering scraper 72 flattens is controlled. The excess fertilizer will slide along the surface of the metering scraper 72 until it falls into the gap of the feed plate 73.

[0025] Please see Figure 2 , Figure 5 and Figure 7 The frame structure 1 includes a front stabilizer 11, a fixed bracket 12 is mounted on the front stabilizer 11, a pull rod 13 is rotatably connected to the fixed bracket 12, a symmetrically distributed rear stabilizer 14 is slidably connected to the front stabilizer 11, a return spring 15 is respectively provided between the front stabilizer 11 and the rear stabilizer 14, and a protective shell 71 is mounted on the rear stabilizer 14.

[0026] By using the above method: by rotating the pull rod 13 connected to the fixed bracket 12, the operator can easily pull the device forward. Through the up-and-down sliding between the front stabilizer 11 and the rear stabilizer 14, and with the help of the return spring 15 set between the front stabilizer 11 and the rear stabilizer 14, the device has room for up-and-down sliding when encountering uneven fertilization trenches during forward movement. At the same time, it avoids the up-and-down fluctuation of the front wheel 2 from affecting the up-and-down fluctuation of the rear wheel 6, thereby ensuring that the distance between the bottom surface of the quantitative scraper 72 and the ground of the fertilization trench is determined.

[0027] Please see Figures 4 to 6The control structure 5 includes symmetrically distributed rotating shafts 51 installed in the front stabilizer 11, and control rods 52 installed between the rotating shafts 51. A limit bracket 53 is installed on the lower side of the front stabilizer 11. A symmetrically distributed sliding block 54 is slidably connected through the limit bracket 53. The sliding block 54 is slidably connected to the control rod 52. A transmission block 55 is installed on the sliding block 54.

[0028] A transmission assembly 56 corresponding to the rotating shaft 51 is installed on the front stabilizer 11. The transmission assembly 56 includes connecting blocks 561 symmetrically distributed on the front stabilizer 11. A rotating rod 562 is rotatably connected through the connecting blocks 561. A drive crank 563 and a driven crank 564 are installed on the rotating rod 562. A sliding rod 565 is slidably connected in the driven crank 564.

[0029] The transmission crank 563 is rotatably connected to the transmission block 55. The sliding discharge baffle 42 is equipped with symmetrically distributed transmission rods 43. The transmission rods 43 are rotatably connected to the sliding rod 565. The distance between the rotating rod 562 and the transmission crank 563 is the same as the horizontal distance of the groove opened on the sliding block 54. The rotating shaft 51 rotates synchronously with the front wheel 2.

[0030] Using the above method: the rotation of the front wheel 2 drives the rotating shaft 51 to rotate synchronously, causing the control rod 52 to rotate around the axis of the rotating shaft 51, which in turn drives the sliding block 54 to slide up and down, causing the transmission block 55 to slide up and down. Then, through the rotational connection between the transmission block 55 and the transmission crank 563, the transmission crank 563 rotates around the rotating rod 562, which in turn drives the driven crank 564 and the sliding rod 565 to rotate synchronously, providing the sliding block 54 with the ability to slide up and down, and thus causing the driven crank 564 and the sliding rod 565 to reciprocate around the rotating rod 562.

[0031] Since the distance between the transmission crank 563 and the rotating rod 562 is the same as the horizontal distance of the sliding groove on the sliding block 54, the transmission crank 563 reciprocates around the rotating rod 562 at ninety degrees. It is connected to the transmission rod 43 through the sliding rod 565, so that the transmission rod 43 slides back and forth in the horizontal direction as the front wheel 2 rotates. This causes the discharge chute 44 on the sliding discharge baffle 42 to be intermittently connected to the trough on the fertilizer hopper 3, so that the fertilizer in the fertilizer hopper 3 is intermittently transported into the fertilizer trench as the front wheel 2 continues to rotate.

[0032] Please see Figures 7 to 9 An isolation shell 74 is installed inside the protective shell 71. The isolation shell 74 is fixedly installed with the metering scraper 72 and the feed plate 73. A guide block 76 is installed inside the metering scraper 72.

[0033] The isolation shell 74 is equipped with a waste material handling chute 75, which is slidably connected to the fertilizer hopper 3. The isolation shell 74 is equipped with a transport scraper 77.

[0034] The rotating shaft of the transport scraper 77 rotates synchronously with the rear wheel 6. The transport scraper 77 is equipped with an array of scrapers. The scrapers of the transport scraper 77 are in frictional engagement with the bottom of the metering scraper 72 and the isolation housing 74.

[0035] Using the above method: the rear wheel 6 rotates along with the front wheel 2, thereby causing the metering scraper 72 to level the fertilizer in the fertilization trench and transport the excess fertilizer along the inclined surface of the metering scraper 72 into the isolation shell 74. Then, the rotation of the rear wheel 6 drives the transport scraper 77 to rotate, and the scraper on the transport scraper 77 transports the excess fertilizer in the isolation shell 74 to the waste material treatment chute 75, and then slides it into the fertilizer hopper 3, forming a fertilizer circulation and avoiding fertilizer waste. At the same time, since there is a vertical sliding space between the waste material treatment chute 75 and the fertilizer hopper 3, even when the height between the front wheel 2 and the rear wheel 6 is different, the waste material treatment chute 75 and the fertilizer hopper 3 are still in a connected state, preventing the fertilizer from falling off.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
