Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a vertical fertilizer dispensing mechanism and a triangular seeder. Background Technology

[0002] The function of a triangular seeder (seeder) is to arrange plants in a triangular pattern in the field using a specific seeding rate or plant spacing. Its principle is to maximize land use and increase yield and economic benefits through appropriate spacing and row spacing. Existing seeders mainly consist of a main frame, wheels, furrowing device, seed metering device, transmission mechanism, soil covering and compaction device, and fertilization mechanism.

[0003] Existing triangular seeders typically place the fertilization mechanism directly below the fertilizer bin. For example, the self-synchronizing triangular seeder disclosed in announcement number CN221768700U requires a large amount of space directly below the fertilizer bin. However, for some seeders, due to the arrangement of other structures, the space directly below the fertilizer bin may not be sufficient to accommodate the fertilization mechanism, making it difficult to fertilize simultaneously with sowing. Utility Model Content

[0004] This utility model provides a vertical fertilizer dispensing mechanism and a triangular seeder. The fertilizer dispensing mechanism can be set at any position below the fertilizer box according to the space arrangement below the fertilizer box.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A vertical fertilizer dispensing mechanism includes a dispensing assembly positioned diagonally below a fertilizer bin. The dispensing assembly includes a dispensing cylinder with a fertilizer inlet on one side, which connects to the outlet of the fertilizer bin. A fertilizer outlet is located on the other side of the dispensing cylinder and connects to a fertilizer application pipe. The line connecting the fertilizer inlet and outlet forms an angle α with the vertical centerline of the fertilizer bin, where α is 0° < α < 90°.

[0007] As a further improvement, the included angle α is 30°≤α≤60°.

[0008] As a further improvement, a rotatable material discharge shaft is provided inside the material discharge cylinder, and blades for guiding the material are connected to the material discharge shaft.

[0009] As a further improvement, the blade is plate-shaped, with its two ends extending toward the two ends of the material feeding shaft; there are multiple blades, which are spaced apart.

[0034] Combination Figure 1 and Figure 2 As shown, this embodiment provides a vertical fertilizer dispensing mechanism for assembly onto a triangular seeder. The seeder includes a fertilizer bin 2 for holding fertilizer.

[0035] Specifically, the vertical fertilizer dispensing mechanism includes a dispensing component 3, which is positioned diagonally below the fertilizer box 2. The dispensing component 3 includes a dispensing cylinder 301, with a fertilizer inlet 308 on one side for connecting to the outlet of the fertilizer box 2; and a fertilizer outlet on the other side for connecting to the fertilizer application pipe 4. The line connecting the fertilizer inlet 308 and the fertilizer outlet forms an angle α with the vertical center line of the fertilizer box 2, where the angle α is 0° < α < 90°, causing the dispensing component 3 to be inclined to the vertical center line of the fertilizer box 2. Fertilizer in the fertilizer box 2 enters the dispensing cylinder 301 through the fertilizer inlet 308 and then enters the fertilizer application pipe 4 through the fertilizer outlet.

[0036] In this design, the material discharge assembly 3 is positioned diagonally below the fertilizer bin 2. Compared to existing seeders where the material discharge assembly is positioned directly below the fertilizer bin 2, this design provides more installation space. Furthermore, positioning the material discharge assembly 3 diagonally below the fertilizer bin 2 facilitates its maintenance.

[0037] Preferably, the included angle α is 30°≤α≤60°. This avoids the included angle α being too large, which would prevent the fertilizer in the fertilizer box 2 from smoothly entering the discharge cylinder 301, and also avoids the included angle α being too small, which would make the discharge assembly 3 inconvenient to install and maintain.

[0038] In one scenario, to maximize the amount of fertilizer in the fertilizer bin 2 that can enter the feeding assembly 3, the lower end of the feeding assembly 3 is installed close to the bottom of the fertilizer bin 2, so that during the final stage of fertilization in the fertilizer bin 2, the fertilizer located at its bottom can still enter the feeding assembly 3.

[0039] Combination Figure 3 and Figure 5 As shown, a rotatable material discharge shaft 310 is provided inside the material discharge cylinder 301, and the material discharge shaft 310 is arranged along the axial direction of the material discharge cylinder 301. A blade 311 for guiding material is also connected to the material discharge shaft 310.

[0040] In one configuration, the blades 311 are plate-shaped, with both ends extending towards the two ends of the discharge shaft 310. Multiple blades 311 are arranged at intervals. Fertilizer enters the discharge cylinder 301 through the fertilizer inlet 308. The rotating discharge shaft 310 drives the blades 311, which propel the fertilizer from one side of the fertilizer inlet 308 to the other side of the fertilizer outlet, ensuring smooth discharge. As a further improvement, to ensure uniform discharge, the blades 311 are arranged in an array around the axial centerline of the discharge shaft 310.

[0041] In another configuration, there is at least one blade 311, each blade 311 being arranged in a spiral around the material discharge shaft 310. Similarly, the rotating material discharge shaft 310 drives the blades 311, which push the fertilizer from one side of the fertilizer inlet 308 to the side of the fertilizer outlet, thus enabling smooth discharge.

[0042] Because there are gaps between adjacent leaves, a baffle 303 is also provided at the end of the discharge shaft 310 near the fertilizer outlet to prevent fertilizer from flowing out from these gaps. The baffle 303 and the side wall of the discharge cylinder 301 accommodate the discharge shaft 310 inside the discharge cylinder.

[0043] To facilitate the connection between the feeding cylinder 301 and the fertilizer application pipe 4, the fertilizer outlet is connected to the fertilizer application pipe 302. Specifically, the inlet of the fertilizer application pipe 302 is connected to the fertilizer outlet of the feeding cylinder 301, and the outlet of the fertilizer application pipe 302 is used to connect to the fertilizer application pipe 4. In one embodiment, a groove is provided on the side of the fertilizer outlet of the feeding cylinder 301, and a retaining edge is provided on the side of the inlet of the fertilizer application pipe 302. The retaining edge is inserted into the groove, thereby connecting the fertilizer application pipe 302 and the feeding cylinder 301. Since the fertilizer outlet of the feeding cylinder 301 is angled downwards, to prevent the fertilizer application pipe 302 from falling off or becoming loose due to bumps during the operation of the seeder, a buckle 307 is also connected to the feeding cylinder 301 to further secure the fertilizer application pipe 302.

[0044] Specifically, the clip 307 is located on the upper side of the fertilizer outlet pipe 302. The fertilizer outlet pipe 302 is provided with a protrusion for snapping, and the clip 307 is snapped onto the protrusion.

[0045] Combination Figure 4 As shown, a movable opening and closing plate 305 is provided at the fertilizer inlet 308. The opening and closing plate 305 is used to adjust the opening size of the fertilizer inlet 308 when it moves. The opening and closing plate 305 is used to close, open, or adjust the opening size of the fertilizer inlet 308, thereby controlling whether fertilization is applied to a specific planting area and the amount of fertilizer applied. A guide plate 309 is provided on the side of the fertilizer inlet 308 along the axial direction of the discharge cylinder 301. A guide groove is provided inside the guide plate 309. The two sides of the opening and closing plate 305 are engaged in the guide groove. When the opening and closing plate 305 moves, it moves within the guide groove, thereby controlling the direction of movement of the opening and closing plate 305.

[0046] Combined Figure 1 As shown, this utility model also provides a triangular seeder, including the aforementioned vertical fertilizer dispensing mechanism, as well as a fertilizer box 2 and a power wheel 1. The vertical fertilizer dispensing mechanism is located diagonally below the fertilizer box 2, with the fertilizer inlet 308 connected to the outlet of the fertilizer box 2, and the fertilizer outlet connected to the fertilizer application pipe 4. Fertilizer in the fertilizer box 2 enters the dispensing cylinder 301 through the fertilizer inlet 308 and enters the fertilizer application pipe 4 through the fertilizer outlet.

[0047] In this design, the power wheel 1 drives the material discharge shaft 310 to rotate. Specifically, the seeder is also equipped with a fertilizer transmission shaft 101. When the power wheel 1 rotates, it drives the fertilizer transmission shaft 101 to rotate. The power wheel 1 can be connected to the fertilizer transmission shaft 101 via a transmission belt or transmission chain. A fertilizer driving wheel 104 is sleeved on the fertilizer transmission shaft 101, and one end of the material discharge shaft 310 is connected to a fertilizer driven wheel 304. The fertilizer driving wheel 104 and the fertilizer driven wheel 304 are connected in cooperation. When the fertilizer transmission shaft 101 rotates, the fertilizer driving wheel 104 rotates synchronously; the fertilizer driving wheel 104 drives the fertilizer driven wheel 304 to rotate, thereby causing the material discharge shaft 310 to rotate.

[0048] like Figure 3 In the middle, the material discharge shaft 310 is perpendicular to the fertilizer transmission shaft 101. Therefore, the fertilizer driving wheel 104 and the fertilizer driven wheel 304 are connected by bevel gears to realize the transmission connection between the fertilizer transmission shaft 101 and the material discharge shaft 310.

[0049] Another embodiment also provides a triangular seeder, wherein the vertical fertilizer dispensing mechanism further includes an adjustable shaft 103 capable of reciprocating forward and reverse rotation, and a fertilizer box 2. The vertical fertilizer dispensing mechanism is located diagonally below the fertilizer box 2, with the fertilizer inlet 308 connected to the outlet of the fertilizer box 2, and the fertilizer outlet connected to the fertilizer application pipe 4. Fertilizer in the fertilizer box 2 enters the dispensing cylinder 301 through the fertilizer inlet 308 and enters the fertilizer application pipe 4 through the fertilizer outlet.

[0050] The adjusting shaft 103 is rotatably connected to the opening and closing plate 305. Specifically, when the adjusting shaft 103 rotates in both directions, it can drive the opening and closing plate 305 to move back and forth.

[0051] As a further improvement, an adjustment drive wheel 105 is connected to the adjustment shaft 103, and the adjustment drive wheel 105 is a gear. A rack 306 is connected to the opening and closing plate 305, and the adjustment drive wheel 105 and the rack 306 are meshed together. When the adjustment shaft 103 rotates, the adjustment drive wheel 105 rotates simultaneously, thereby driving the rack 306 to move, which in turn causes the opening and closing plate 305 to move.

[0052] One end of the adjusting shaft 103 is provided with an adjusting connection end 102, and a handle can be connected to the adjusting connection end 102. By manually operating the handle, the adjusting shaft 103 can be rotated. Of course, in other embodiments, the adjusting shaft 103 can also be rotated in other ways.

[0053] Of course, the above-mentioned seeder structures can be combined and used on a single seeder, all of which are within the protection scope of this utility model.

[0054] The triangular seeder of this utility model is also equipped with a support frame, and the parts that need to be fixed are connected to the support frame, such as fertilizer box 2, feed cylinder 301, etc.

[0055] The terms "installation," "setup," "equipped with," and "connection" used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0056] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
