Description

Technical Field

[0001] The invention relates to the technical field of fertilizer application equipment, in particular to a fertilizer application machine with adjustable fertilizer application amount. Background Art

[0002] In modern agricultural production, fertilization is an indispensable part of crop growth. Its accuracy and efficiency are directly related to the yield and quality of crops. However, traditional fertilizer applicators have a series of technical difficulties in the fertilization process, which makes it difficult to meet the needs of modern agriculture for precision agriculture and high-efficiency agriculture.

[0003] First of all, traditional fertilizer spreaders have deficiencies in controlling the fertilizer spreading area. Faced with plots of different sizes, traditional fertilizer spreaders are difficult to flexibly adjust the fertilizer spreading range and the material dropping speed. On large plots of land, if the fertilizer spreading range is too small or the material dropping speed is too slow, the fertilization efficiency will be low and the time requirements of agricultural production cannot be met; on small plots of land, if the fertilizer spreading range is too large or the material dropping speed is too fast, it is easy to cause excessive fertilizer spreading outside the plot, which not only wastes fertilizer but also may pollute the surrounding environment. Moreover, for a spreading fertilizer spreader, when working on a plot with a large ground slope, such as a mountain orchard or other area with complex terrain, the fertilizer feed pipe of the fertilizer spreader will tend to deviate to one side due to gravity when transporting fertilizer, and cannot accurately fall into the center of the throwing plate. This offset phenomenon will cause the fertilizer to be unevenly distributed during the rotation of the throwing plate, with too much fertilizer in some areas and insufficient fertilizer in some areas. This will not only reduce the utilization rate of the fertilizer, but also affect the uniformity of crop growth, and thus affect the overall yield and quality. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, reference Figure 1 to Figure 10 , is the first embodiment of the present invention, which provides a fertilizer spreader with adjustable fertilizer amount. The fertilizer spreader with adjustable fertilizer amount includes a main body component 100, including a mounting frame 101, a hopper 102, a feed pipe 103, a support plate 104, a drive motor 105, a rotating shaft 106, a rotating disk 107 and a fertilizer application member 108. The hopper 102 is fixed in the mounting frame 101, the feed pipe 103 is fixed to the bottom of the hopper 102, the support plate 104 is fixed in the mounting frame 101, the drive motor 105 is fixed to the bottom of the support plate 104, the rotating shaft 106 is rotatably connected in the support plate 104, the rotating disk 107 is fixed to the top of the rotating shaft 106, and the fertilizer application member 108 is arranged on the top of the rotating disk 107.

[0034] The mounting frame 101 is used to fix the fertilizer spreader on the agricultural machine to facilitate fertilization, the hopper 102 is used to hold the fertilizer, the discharge pipe 103 is used to discharge the fertilizer in the hopper 102, and the support plate 104 is used to fix and support the driving motor 105. The driving motor 105 is used to drive the rotating shaft 106 to rotate, so that the rotating shaft 106 drives the rotating disk 107 to rotate, so that the rotating disk 107 drives the fertilizer application part 108 to rotate, so that the fertilizer dropped from the discharge pipe 103 is thrown out by the fertilizer application part 108.

[0035] The adjusting assembly 200 is arranged on the fertilizer applying member 108, and comprises a throwing disc 201a fixed on the top of the rotating disc 107, a material mixing ring 201b is arranged on the top of the throwing disc 201a, a groove 201a-1 is opened in the throwing disc 201a, a lever 201c is fixed on the inner wall of the groove 201a-1, a stirring rod 201d is fixed on the top of the throwing disc 201a, a lifting rod 201e is fixed on the top of the material mixing ring 201b, a lifting ring 201f is fixed on the top of the lifting rod 201e, a sealing ring 201g is fixed on the bottom of the feeding tube 103, and a sealing shell 201h is fixed on the surface of the feeding tube 103.

[0036] The rotating disk 107 is used to drive the throwing disk 201a to rotate, so that the throwing disk 201a and the material leveling ring 201b will rotate relative to each other. The throwing disk 201a is used to receive the fertilizer dropped from the feeding pipe 103, and the material leveling ring 201b is used to evenly spread the fertilizer dropped on the surface of the throwing disk 201a, so that the fertilizer will not accumulate on one side of the throwing disk 201a, thereby eliminating the influence of gravity caused by the tilt of the plot, so that the fertilizer can evenly enter the fertilizer application member 108, and the ... The relative rotation between the material distribution ring 201a and the material distribution ring 201b makes it difficult for the fertilizer to be blocked between the throwing disk 201a and the material distribution ring 201b, and makes it easier to spread the fertilizer evenly. The setting of the sealing ring 201g can prevent the fertilizer from passing over the material distribution ring 201b. By moving the lifting ring 201f up and down, the lifting rod 201e can drive the material distribution ring 201b to move up and down, so that the material distribution ring 201b can be adjusted according to the feeding speed of the feeding pipe 103.

[0037] When the feeding speed of the lower feeding pipe 103 is fast, the material leveling ring 201b can be moved upward to increase the gap between the material leveling ring 201b and the throwing plate 201a. At this time, more fertilizers can pass through per unit time; when the feeding speed of the lower feeding pipe 103 is slow, the material leveling ring 201b can be moved downward to reduce the gap between the material leveling ring 201b and the throwing plate 201a. At this time, a small amount of fertilizer will also be evenly distributed on the surface of the throwing plate 201a, and will not all be moved out from one side of the throwing plate 201a.

[0038] The lever 201c fixed on the inner wall of the groove 201a-1 can drive the fertilizer in the groove 201a-1 to move, so that the fertilizer in the groove 201a-1 is thrown to the inner wall of the sealed shell 201h and then falls downward from the sealed shell 201h. The stirring rod 201d can be used to move the fertilizer to make the fertilizer more evenly distributed.

[0039] When the rotating disk 107 stops rotating, the throwing disk 201a also stops rotating. At this time, the fertilizer will accumulate in the groove 201a-1 and will not fall off the throwing disk 201a, so that the fertilizer spreader can stop fertilizing.

[0040] Specifically, the fertilizer application member 108 includes a rotating seat 108a fixed to the top of the rotating disk 107, a throwing tube 108b is fixed on the surface of the rotating seat 108a, a supporting rod 108c is rotatably connected inside the throwing tube 108b, and a springboard 108d is fixed to the end of the supporting rod 108c.

[0041] The support rod 108c is used to support the springboard 108d. By rotating the rotating disk 107, the rotating seat 108a drives the throwing tube 108b to move. At this time, the fertilizer dropped from the throwing disk 201a will be evenly thrown out from several throwing tubes 108b.

[0042] By rotating the support rod 108c to adjust the angle of the springboard 108d, the fertilizer in the throwing tube 108b can be thrown out at different angles, thereby adjusting the fertilizer spreading area, so that the fertilizer spreader is better suitable for different plots of land.

[0043] Specifically, the adjustment component 200 also includes a discharge part 202, which is arranged on the discharge tube 103, including a rotating rod 202a rotatably connected to the discharge tube 103, a baffle 202b is fixed on the surface of the rotating rod 202a, a driving gear 202c is fixed on the surface of the rotating rod 202a, a limiting sleeve 202d is fixed on one side of the discharge tube 103, a lifting frame 202e slides in the limiting sleeve 202d, the driving gear 202c is meshed with the lifting frame 202e, and the lifting frame 202e is fixed to the inner wall of the lifting ring 201f.

[0044] The rotating rod 202a is used to drive the baffle 202b to move. When the baffle 202b is in a horizontal state, the feeding pipe 103 can be blocked, so that the feeding pipe 103 stops feeding. By adjusting the angle of the baffle 202b, the feeding speed of the feeding pipe 103 can be adjusted.

[0045] The limiting sleeve 202d is used to limit the lifting frame 202e, so that the lifting frame 202e can be lifted and lowered stably. When the baffle 202b is opened by the rotating rod 202a, the rotating rod 202a can drive the driving gear 202c to rotate, so that the driving gear 202c drives the lifting frame 202e to move upward, so that the lifting frame 202e drives the lifting ring 201f to move upward. At this time, the lifting ring 201f can drive the material leveling ring 201b to move upward, so that the gap between the material ring 201b and the throwing plate 201a is increased. As the opening angle of the baffle 202b increases, the material discharge speed of the feeding pipe 103 becomes faster, and the gap between the material ring 201b and the throwing plate 201a will also increase, so that the fertilizer with different feeding speeds can be evenly spread.

[0046] Specifically, the adjustment component 200 also includes an adjustment member 203, which is arranged on the ejection tube 108b, including an adjustment rod 203a fixed to the surface of the support rod 108c, the other end of the adjustment rod 203a is rotatably connected to a connecting rod 203b, and the other end of the connecting rod 203b is fixed to a driving rod 203c.

[0047] The adjusting rod 203a is used to drive the supporting rod 108c to rotate, the connecting rod 203b is used to pull the adjusting rod 203a, and the driving rod 203c is used to pull the two connecting rods 203b. Pulling the driving rod 203c upwards can make the connecting rod 203b drive the supporting rod 108c to rotate through the adjusting rod 203a, so as to adjust the angle of the springboard 108d, thereby adjusting the fertilizer spreading area, so that the fertilizer spreader can be better adapted to different plots of land.

[0048] Specifically, the adjusting member 203 further comprises a fixing frame 203d fixed to the surface of the throwing tube 108b, a lifting column 203e slides inside the fixing frame 203d, an adjusting disk 203f is fixed on the top of the lifting column 203e, and a driving rod 203c is rotatably connected to the lifting column 203e.

[0049] The fixing frame 203d is used to limit the lifting column 203e so that the lifting column 203e can be stably lifted and lowered. By moving the adjustment disk 203f, multiple lifting columns 203e can be driven to be lifted and lowered simultaneously, thereby adjusting multiple springboards 108d at the same time.

[0050] Example 2, reference Figure 1 to Figure 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0051] Specifically, the adjustment component 200 also includes a power part 204, which is arranged on the surface of the discharge pipe 103, including a fixed block 204a fixed to the surface of the discharge pipe 103, and a driving shaft 204b is rotatably connected inside the fixed block 204a. An adjustment motor 204c is fixed at the end of the driving shaft 204b, and the adjustment motor 204c is fixed to one side of the discharge pipe 103.

[0052] The fixing block 204a is used to support the driving shaft 204b, and the adjusting motor 204c is used to drive the driving shaft 204b to rotate.

[0053] Specifically, a worm 204d is rotatably connected to the surface of the driving shaft 204b, a fan-shaped worm wheel 204e is fixed to the surface of the baffle 202b, and the worm 204d is meshed with the fan-shaped worm wheel 204e.

[0054] The worm 204d can be rotated to drive the fan-shaped worm wheel 204e to move, so that the fan-shaped worm wheel 204e can drive the baffle 202b to rotate, thereby adjusting the angle of the baffle 202b.

[0055] Specifically, an adjustment block 204f is fixed at the bottom of the worm 204d, and an extrusion column 204g is rotatably connected to the adjustment block 204f through a thread. A positioning groove 204b-1 is opened on the surface of the driving shaft 204b, and the end of the extrusion column 204g is inserted into the positioning groove 204b-1.

[0056] By rotating the adjustment block 204f, the worm 204d can be driven to rotate, thereby facilitating the adjustment of the worm 204d. By inserting the extrusion column 204g into the positioning groove 204b-1, the drive shaft 204b can drive the worm 204d to rotate synchronously, so that the adjustment motor 204c can drive the baffle 202b to move.

[0057] When fertilizing different varieties of crops, the squeezing column 204g can be rotated to make the squeezing column 204g move away from the positioning groove 204b-1. At this time, the driving shaft 204b is kept stationary, and the worm 204d is rotated to adjust the angle of the baffle 202b, so that the feeding tube 103 can discharge materials at a suitable speed, and then the squeezing column 204g is rotated in the opposite direction to reinsert the squeezing column 204g into the positioning groove 204b-1, and the worm 204d and the driving shaft 204b are fixedly connected.

[0058] Specifically, a slide groove 204h is fixed on one side of the discharge pipe 103, a threaded sleeve 204i is rotatably connected to the surface of the drive shaft 204b through a thread, a slider 204j is fixed to one side of the threaded sleeve 204i, a clamping column 204k is fixed to the other side of the threaded sleeve 204i, and a support wheel 204l is rotatably connected inside the clamping column 204k.

[0059] The slide groove 204h is used to limit the slider 204j, so that the slider 204j can move up and down stably in the slide groove 204h, thereby limiting the threaded sleeve 204i to prevent the threaded sleeve 204i from rotating. The support wheel 204l is used to support the adjusting disk 203f.

[0060] When the driving shaft 204b rotates, the threaded sleeve 204i can be driven to move up and down, thereby driving the adjusting disk 203f to move up and down through the supporting wheel 204l, thereby adjusting the angle of the springboard 108d in the throwing tube 108b, so that the fertilizer in the throwing tube 108b is thrown out at different angles, thereby adjusting the fertilizer spreading area, so that the fertilizer spreader can be better suitable for different plots of land.

[0061] When the threaded sleeve 204i moves upward, the springboard 108d can be tilted up to increase the fertilizer spreading area. The driving shaft 204b can simultaneously drive the fan-shaped worm gear 204e to move, so that the opening angle of the baffle 202b is larger, thereby accelerating the unloading speed of the unloading pipe 103 and the feeding speed of the fertilizer, so as to adapt to the larger spreading area and avoid causing excessive difference in the amount of fertilizer per unit area before and after the spreading area is adjusted, thereby ensuring the stability of fertilization.

[0062] Specifically, the surface of the lifting frame 202e is provided with scales.

[0063] By setting uniform scales on the surface of the lifting frame 202e, the user can understand the opening angle of the baffle 202b through the scales, thereby digitizing the unloading speed of the unloading pipe 103.

[0064] When in use, the feeding speed of the feeding pipe 103 is adjusted according to the crops planted in the current plot.

[0065] First, the extrusion column 204g can be rotated so that the extrusion column 204g is away from the positioning groove 204b-1. At this time, the drive shaft 204b is kept stationary and the worm 204d is rotated to adjust the angle of the baffle 202b, so that the discharge pipe 103 can discharge the material at a suitable speed. Then, the extrusion column 204g is rotated in the opposite direction so that the extrusion column 204g is reinserted into the positioning groove 204b-1, and the worm 204d and the drive shaft 204b are fixedly connected.

[0066] At this time, the driving motor 105 is started to drive the rotating shaft 106 to rotate, so that the rotating shaft 106 drives the rotating disk 107 to rotate, so that the rotating disk 107 drives the fertilizing member 108 to rotate, and the fertilizer in the throwing tube 108b can be thrown out, thereby scattering the fertilizer.

[0067] When encountering a tilted plot of land, the fertilizer enters the top of the throwing plate 201a from the feeding pipe 103, and the fertilizer can be evenly spread through the gap between the material leveling ring 201b and the throwing plate 201a, so that the thrown fertilizer will not be unevenly applied due to the influence of gravity.

[0068] When it is necessary to adjust the area of ​​fertilizer spreading, start the adjustment motor 204c, which can drive the drive shaft 204b to rotate, so that the drive shaft 204b drives the threaded sleeve 204i to move up and down, and the threaded sleeve 204i drives the clamping column 204k to move up and down. At this time, the clamping column 204k drives the adjustment disk 203f to move up and down through the support wheel 204l, thereby adjusting the angle of the springboard 108d in the throwing tube 108b, so that the fertilizer in the throwing tube 108b is thrown out at different angles, thereby adjusting the fertilizer spreading area, so that the fertilizer spreader can be better suitable for different plots of land.

[0069] When adjusting the area of ​​fertilizer spreading, if the threaded sleeve 204i moves upward, the springboard 108d can be tilted up to increase the fertilizer spreading area, and the driving shaft 204b can simultaneously drive the fan-shaped worm gear 204e to move, so that the opening angle of the baffle 202b is larger, thereby accelerating the feeding speed of the feeding pipe 103 and the feeding speed of the fertilizer, so as to adapt to a larger spreading area, and will not cause a large difference in the amount of fertilizer per unit area before and after the spreading area is adjusted, thereby ensuring the stability of fertilization.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
