DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0033] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0034] Many fertilizers, such as nitrogen fertilizers (urea, ammonium nitrate, etc.) and potash fertilizers (potassium chloride, potassium sulfate, etc.), are highly hygroscopic. They easily absorb moisture from the air, making their surfaces moist, and then stick to each other to form lumps. Therefore, during the fertilization process, it is easy for fertilizers to clump together. If the lumped fertilizers are directly spread on the surface, the surface fertilizers at the lumped fertilizers will increase, resulting in uneven fertilization.

[0035] In order to solve the above problems, the present application provides a fertilization mechanism, which can move the storage part 200 during the fertilization process by movably installing the storage part 200 on the support part 100. When the storage part 200 moves, the fertilizer in the storage part 200 generates a certain interaction force, which makes it difficult for the fertilizer to clump. At the same time, the agglomerated fertilizer can also be dispersed under the action of the interaction force, thereby avoiding uneven fertilization when the fertilizer clumps, thereby improving the utilization rate of the fertilizer.

[0036] The following is combined with Figures 1 to 5 , a fertilization mechanism and a multifunctional seeder provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0037] The first aspect of this embodiment provides a detailed description of a fertilizing mechanism.

[0038] Reference Figure 1 , Figure 2 A fertilization mechanism includes a support portion 100, a storage portion 200, a discharge pipe 300 and a distribution portion 400. The support portion 100 is used to provide an installation foundation. During use, the mobile support portion 100 will drive the fertilization mechanism to move relative to the ground surface, thereby facilitating fertilization in different areas. It can be understood that in order to fertilize different areas, a walking device, such as wheels, etc., can be installed on the support portion 100 to facilitate the movement of the support portion 100. The support portion 100 can also be installed on a vehicle, such as a seeder, so that fertilization can be completed while sowing.

[0039] The storage part 200 is movably arranged on the support part 100, so that the storage part 200 is movable relative to the support part 100, so that the fertilizer in the storage part 200 can generate a mutual force. The storage part 200 is movably arranged on the support part 100, which means that the storage part 200 can rotate or move relative to the support part 100. In some embodiments, the storage part 200 is funnel-shaped so that the fertilizer in the storage part 200 can be completely discharged from the storage part 200. In some embodiments, a stopper (not shown in the figure) can be provided on the inner wall of the storage part 200, so that when the storage part 200 moves relative to the support part 100, a relative force is generated between the stopper and the fertilizer in the storage part 200, which is conducive to the dispersion of the agglomerated fertilizer.

[0040] Reference Figure 1 , Figure 2 The discharge pipe 300 is arranged on the support part 100, and the discharge pipe 300 is movably connected with the storage part 200. The discharge pipe 300 is used to guide the fertilizer in the storage part 200 to flow to the desired position. The discharge pipe 300 includes a discharge port 310. After the fertilizer in the storage part 200 enters the discharge pipe 300, it will be discharged from the discharge port 310. In some embodiments, the discharge pipe 300 is a pipe structure with openings at both ends, such as a hard pipe.

[0041] The material distribution part 400 is rotatably arranged on the support part 100 with the first rotating shaft as the rotation center. The material distribution part 400 includes a rotating surface 410 with the first rotating shaft as the central axis. The material distribution part 400 is provided with a material distribution trough 420. The notch of the material distribution trough 420 is located on the rotating surface 410. The discharge port 310 is in contact with the rotating surface 410. When the material distribution part 400 rotates, the discharge port 310 can be connected with the notch of the material distribution trough 420. In some embodiments, the material distribution part 400 is a cylindrical structure, the rotating surface 410 is the side wall of the cylindrical structure, and the first rotating shaft is the central axis of the cylindrical structure. In other embodiments, the material distribution part 400 is an annular structure, the rotating surface 410 is the outer wall of the annular structure, and the first rotating shaft is the central axis of the annular structure.

[0042] Reference Figure 1 , Figure 2It is understood that in order to keep the discharge port 310 and the rotating surface 410 in contact with each other, the discharge pipe 300 needs to be fixed relative to the support part 100, so that when the distribution part 400 rotates, the discharge port 310 can always be in contact with the rotating surface 410. In order to facilitate the entry of fertilizer into the distribution trough 420, the distribution part 400 is arranged below the storage part 200, and the lowering can be directly below or obliquely below, so that the fertilizer can move into the distribution trough 420 under the action of gravity. It is understood that in some embodiments, the distribution part 400 can be above the storage part 200 or at the same height as the storage part 200. At this time, the fertilizer in the storage part 200 needs to be transported to the distribution part 400 by a conveying mechanism, and the conveying mechanism can be a screw pump or a similar pushing structure. In order to ensure uniform rotation of the material distribution part 400, the material distribution part 400 can be driven to rotate by a driving structure such as a motor 610. Compared with manual rotation, the rotation speed is easier to adjust when the material distribution part 400 is driven to rotate by the motor 610.

[0043] During use, the fertilizer is loaded into the storage part 200, and part of the fertilizer in the storage part 200 will enter the discharge pipe 300. Since the discharge port 310 is in contact with the rotating surface 410, the fertilizer will stay in the storage part 200 and the discharge pipe 300 under the action of the rotating surface 410. As the distribution part 400 rotates, the notch of the distribution trough 420 will be connected to the discharge port 310. At this time, under the action of the gravity of the fertilizer in the storage part 200 and the discharge pipe 300, the fertilizer will enter the distribution trough 420. By controlling the rotation of the distribution part 400, the fertilizer can be transported to the distribution trough 420. The speed is to ensure that the fertilizer can completely fill the material distribution trough 420. As the material distribution part 400 continues to rotate, the material distribution trough 420 will be separated from the discharge port 310. When the notch of the material distribution trough 420 rotates to face the ground or tilts to the ground side, the fertilizer in the material distribution trough 420 will be gradually poured out from the material distribution trough 420 to complete the fertilization. By moving the support part 100 while the material distribution part 400 rotates, different ground surfaces can be fertilized. During the fertilization process, the rotation speed of the material distribution part 400 and the moving speed of the support part 100 can be controlled to control the density of the fertilization. In this process, by allowing the storage part 200 to move relative to the support part 100, the fertilizer can be effectively prevented from caking in the storage part 200. At the same time, a certain amount of fertilizer flow can be generated in the discharge pipe 300 under the action of the gravity of the fertilizer, thereby improving the uniformity of fertilization.

[0044] Reference Figure 2 , Figure 3According to an optional embodiment, the storage portion 200 is movably arranged on the support portion 100 in a direction approaching / moving away from the distribution portion 400. When the distribution portion 400 is located below the storage portion 200, the storage portion 200 moves in a direction approaching / moving away from the distribution portion 400, which can lower or raise the level of the fertilizer in the storage portion 200. In this process, it is beneficial for the fertilizer in the storage portion 200 to generate an interaction force, thereby preventing the fertilizer from agglomerating. At the same time, it can also make it easier for the fertilizer to enter the discharge pipe 300, thereby facilitating the generation of a uniform fertilizer flow in the discharge pipe 300.

[0045] According to an optional embodiment, at least a portion of the discharge pipe 300 is located in the material storage portion 200. Since the discharge pipe 300 is movable relative to the material storage portion 200, when the material storage portion 200 moves relative to the support portion 100, the discharge pipe 300 located in the material storage portion 200 can move relative to the material storage portion 200, thereby enabling the discharge pipe 300 located in the material storage portion 200 to push the fertilizer in the material storage portion 200 to move, making it easier for the fertilizers inside the material storage portion 200 to generate interaction forces, and allowing the fertilizers agglomerated in the material storage portion 200 to be easier to disperse.

[0046] Reference Figure 2 , Figure 3 According to an optional embodiment, the storage section 200 includes a movable hole 210, and one end of the discharge pipe 300 away from the discharge port 310 is slidably connected to the movable hole 210 in a direction close to / away from the distribution section 400. When the storage section 200 moves, the discharge pipe 300 will slide in the movable hole 210, thereby changing the length of the discharge pipe 300 extending into the storage section 200. When the length of the discharge pipe 300 located inside the storage section 200 increases, the storage pipe will push the fertilizer in the storage section 200. When the length of the discharge pipe 300 located inside the storage section 200 decreases, the fertilizer will fall back under the action of gravity. In this way, the length of the discharge pipe 300 in the storage section 200 increases or decreases cyclically, which can enable the fertilizer in the storage section 200 to generate a stable internal force, thereby avoiding fertilizer agglomeration, and also allowing the agglomerated fertilizer to be dispersed in time. It can be understood that the sliding connection of the discharge pipe 300 in the movable hole 210 means that the outer wall of the discharge pipe 300 fits with the inner wall of the movable hole 210, so that the fertilizer will not leak out from the gap between the movable hole 210 and the discharge pipe 300. In some embodiments, the discharge pipe 300 may also be matched with the movable hole 210 with a gap smaller than the diameter of the fertilizer particles, so that the fertilizer will not leak out from the gap between the movable hole 210 and the discharge pipe 300.

[0047] Reference Figure 3 , Figure 4According to an optional embodiment, a pusher 320 is provided on the discharge pipe 300 located in the storage part 200. The pusher 320 is used to increase the contact area between the discharge pipe 300 and the fertilizer. In some embodiments, the pusher 320 is a protrusion protruding from the outer wall of the discharge pipe 300. The contact area between the discharge pipe 300 and the fertilizer can be increased by the protrusion. When the discharge pipe 300 moves relative to the storage part 200, the discharge pipe 300 exerts a greater force on the fertilizer in the storage part 200, which helps to increase the interaction force between the fertilizers in the storage part 200. At the same time, the protrusion can prevent the discharge pipe 300 from being disengaged from the storage part 200, and improve the tightness of the fit between the discharge pipe 300 and the storage part 200.

[0048] Reference Figure 1 , Figure 2 According to an optional embodiment, a shielding part 500 is arranged around the rotating surface 410, the shielding part 500 is connected to the supporting part 100, the shielding part 500 is in contact with the rotating surface 410, the shielding part 500 includes a first notch 510 and a second notch 520, the discharging pipe 300 is in contact with the rotating surface 410 through the first notch 510, and when the material distribution trough 420 rotates with the material distribution part 400, the material distribution trough 420 can rotate to the second notch 520, so that the fertilizer in the material distribution trough 420 can be discharged through the second notch 520. It can be understood that the shielding part 500 is in contact with the rotating surface 410, which means that the shielding part 500 and the rotating surface 410 are completely in contact with each other, or the gap between the two is very small, and the gap between the two is smaller than the size of the fertilizer particles, so that the fertilizer particles will not leak out from between the two.

[0049] When the material distribution part 400 rotates, the notch of the material distribution trough 420 will gradually face the ground, and the fertilizer in the material distribution trough 420 will be continuously poured out from the material distribution trough 420 until the notch of the material distribution trough 420 faces the vertical downward direction, and all the fertilizer in the material distribution trough 420 will be completely poured out. When planting some special crops, such as taro, potatoes, etc., the best fertilization situation is to concentrate the fertilizer near the planting area. For this reason, it is necessary to make the fertilizer in the material distribution trough 420 completely poured out only at a specific time, so by setting the shielding part 5 00, when fertilization is not needed, the notch of the feed trough 420 can be covered by the shielding portion 500, and the fertilizer in the feed trough 420 will not be poured out from the feed trough 420. When the notch of the feed trough 420 is located at the position of the second notch 520, the fertilizer in the feed trough 420 will be poured out all at once due to the absence of the shielding portion 500. At this time, the fertilizer will all fall in the required area, thereby improving the utilization rate of the fertilizer and avoiding the situation where the fertilizer cannot be effectively absorbed by the plants when it is sprinkled in an area where crops are not planted. In some embodiments, the second notch 520 is vertically downward, that is, when the notch of the feed trough 420 is rotated to be vertically downward, the fertilizer in the feed trough 420 can be poured out from the feed trough 420.

[0050] According to an alternative embodiment, referring to Figure 2 , Figure 3 , there are at least two feed troughs 420, and the slots of at least two feed troughs 420 are arranged on the rotating surface 410 at intervals. By setting different numbers of feed troughs 420, the fertilization spacing can be controlled to meet different fertilization needs. It can be understood that a baffle or other structure can also be arranged in the feed trough 420 to change the depth of the feed trough 420, so that the volume of the feed trough 420 changes, thereby controlling the amount of fertilizer that can be contained in each feed trough 420 to meet various fertilization needs. For example, a baffle (not shown in the figure) is detachably installed on the side wall or bottom wall of the feed trough 420 by bolts or magnets to reduce the volume of the feed trough 420. The slots of at least two feed troughs 420 are arranged on the rotating surface 410 at intervals, which means that when there are two or more feed troughs 420, adjacent feed troughs 420 are arranged at intervals, and the interval setting can be equal spacing or unequal spacing. At the same time, they can be arranged at intervals along the first axial direction, or can be arranged at intervals along the circumferential direction of the revolving surface 410.

[0051] According to an alternative embodiment, referring to Figure 1 , Figure 3 A crank slider mechanism 600 is provided between the support portion 100 and the material storage portion 200, and the crank slider mechanism 600 is used to drive the material distribution portion 400 to slide in a direction close to / away from the material distribution portion 400. In some embodiments, the crank slider mechanism 600 includes a motor 610, a connecting rod 620 is connected to the rotating shaft of the motor 610, a swing rod 630 is hinged on the connecting rod 620, and an end of the swing rod 630 away from the connecting rod 620 is hinged to the material storage portion 200. When the motor 610 drives the connecting rod 620 to rotate, the connecting rod 620 will drive the swing rod 630 to swing, thereby pushing the material storage portion 200 to slide in a direction close to / away from the material distribution portion 400.

[0052] The second aspect of this embodiment provides a detailed description of a multifunctional seeder.

[0053] Reference Figure 1 , Figure 5 A multifunctional seeder includes a walking mechanism 700, the walking mechanism 700 is provided with a fertilizing mechanism in the above embodiment, and a support part 100 is installed on the walking mechanism 700, that is, the fertilizing mechanism can be installed on the walking mechanism 700, wherein the support part 100 installed on the walking mechanism 700 can be an integral setting or a detachable connection.

[0054] According to an optional embodiment, the walking mechanism 700 is provided with a fertilizer channel 710, and the fertilizer channel 710 allows the fertilizer discharged from the second gap 520 to fall to the surface where fertilization is required. Due to the structural limitations of the walking mechanism 700, the fertilizer coming out of the second gap 520 may be blocked by the walking mechanism 700. By providing the fertilizer channel 710, the fertilizer coming out of the second gap 520 can be guided to the desired ground surface, thereby improving the fertilization accuracy.

[0055] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
