When the first joint and the second joint are separated, the adjusting device drives the fertilizer dispensing shaft to move axially. When the first joint and the second joint are engaged, the adjusting device rotates synchronously with the fertilizer dispensing shaft.

[0007] Furthermore, the adjusting device includes a threaded rod, and the second engaging portion is slidably disposed on the outside of the threaded rod; a limiting groove is provided on the outside of the threaded rod along its axial direction, and the second engaging portion is provided with a limiting pin block that cooperates with the limiting groove; one end of the threaded rod is connected to the fertilizer shaft, and the other end is connected to a knob; the first engaging portion is mounted on one side of the fertilizer box through a fixing seat, and the first engaging portion is rotatably connected to the fixing seat; the threaded rod passes through the first engaging portion.

[0008] Furthermore, the first joint and the second joint are each provided with engagement teeth at the joint position, and the engagement teeth of the two are locked together.

[0009] Furthermore, one end of the fertilizer box is connected to a fertilizer outlet, and the other end is provided with a discharge outlet. The rotating surface of the rotating block is provided with a fertilizer trough for accommodating fertilizer, and the length direction of the fertilizer trough is consistent with the central axis direction of the rotating block.

[0010] Furthermore, the discharge port is connected to a fertilizer application pipe, which extends towards the ground.

[0011] Furthermore, the fertilizer box is equipped with a partition that divides the inside of the fertilizer box into a first fertilization area and a second fertilization area.

[0028] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0029] Reference Figures 1-2 This application provides a triangular mulching seeder, including a frame 300, a mulching mechanism 500, a sowing mechanism 600, and a fertilizing mechanism. Ground wheels 400 are provided on both sides of the frame 300, and the ground wheels 400 are connected to the fertilizing mechanism via a transmission assembly. The ground wheels 400 drive the entire seeder to move and sow seeds, while the fertilizing mechanism applies fertilizer under the drive of the ground wheels 400 and the transmission assembly. The mulching mechanism 500 and the sowing mechanism 600 can also operate while the seeder is moving. In the direction of travel, the mulching mechanism 500 is located behind the fertilizing mechanism, and the sowing mechanism 600 is located behind the mulching mechanism 500. The mulching mechanism 500 mulches the ridges, and the sowing mechanism 600 punctures the mulch film on the mulched ridges to sow seeds. The mulching mechanism 500 includes a mulching shaft 510 and a pressing roller 520. The mulching shaft 510 is used to mount rolled mulch film, and the pressing roller 520 is used to press the unfolded mulch film firmly. The sowing mechanism 600 includes a seed box 610 and a seeder 620. The seed box 610 is connected to the seeder 620. Seeds enter the seeder 620 from the seed box 610. The seeder 620 runs along the direction of the mulch film laying. The seeder 620 is prior art, such as the structure disclosed in the patent document with authorization announcement number CN2292373Y.

[0030] In order to achieve controllable fertilizer application, in some embodiments, such as Figure 3As shown, the fertilization mechanism includes a fertilizer box 100, which has multiple fertilizer outlets at its bottom and a fertilizer dispensing device 200 at each outlet. The fertilizer dispensing device 200 includes a fertilizer box 210, a rotating block 220, a fertilizer dispensing shaft 230, and an adjusting device 240. One end of the fertilizer box 210 is connected to the bottom of the fertilizer outlet, and the other end has a discharge outlet. The rotating surface of the rotating block 220 has a fertilizer trough for receiving fertilizer, and the length direction of the fertilizer trough is consistent with the central axis direction of the rotating block 220. The fertilizer dispensing shaft 230 passes through the rotation center of the rotating block 220 and is connected to the rotating block 220. The rotating block 220 is positioned through the fertilizer box 210 and is located between the fertilizer outlet and the discharge outlet. The fertilizer dispensing shaft 230 drives the rotating block 220 to rotate synchronously by rotating, thereby ensuring that the fertilizer box 210 dispenses fertilizer smoothly. An adjusting device 240 is provided at one end of the fertilizer dispensing shaft 230. The adjusting device 240 includes a separable first joint 241 and a second joint 242. When the first joint 241 and the second joint 242 are separated, the adjusting device 240 drives the fertilizer dispensing shaft 230 to move axially. Controlling the axial movement of the fertilizer dispensing shaft 230 can drive the rotating block 220 to move axially, changing the position of the rotating block 220 in the fertilizer dispensing box 210. The position of the fertilizer trough changes, and the proportion of the fertilizer trough in the fertilizer falling path changes, which can reduce or increase the interception of fertilizer, thereby adjusting the amount of fertilizer applied. When the first joint 241 and the second joint 242 are engaged, the adjusting device 240 rotates synchronously with the fertilizer dispensing shaft 230. The rotation of the fertilizer dispensing shaft 230 drives the rotating block 220 to rotate simultaneously, which is conducive to the smooth dispensing of fertilizer from the fertilizer dispensing box 210. Moreover, after the first joint 241 and the second joint 242 are engaged, they can rotate synchronously with the fertilizer dispensing shaft 230. The first joint 241 and the second joint 242 can flexibly switch the movement state of the thick shaft 230.

[0031] Specifically, such as Figure 4 and Figure 5As shown, the adjusting device 240 includes a threaded rod 244, and a second engagement portion 242 of the threaded rod 244 is slidably disposed on the outside of the threaded rod 244. A limiting groove 245 is provided on the outside of the threaded rod 244 along its axial direction. The second engagement portion 242 is provided with a limiting pin 243 that cooperates with the limiting groove 245. The limiting pin 243 can restrict the axial rotation of the second engagement portion 242 on the outside of the threaded rod 244. When the second engagement portion 242 engages with the first engagement portion 241, it restricts the independent rotation of the threaded rod 244, so that the threaded rod 244, the first engagement portion 241 and the second engagement portion 242 form a whole. One end of the threaded rod 244 is connected to the fertilizer discharge shaft 230, and the other end is connected to the knob 246. The first joint 241 is mounted on one side of the fertilizer box 100 via a fixed seat 247, and the first joint 241 is rotatably connected to the fixed seat 247. The threaded rod 244 passes through the first joint 241 and the fixed seat 247 and is threadedly connected to the other side of the fertilizer box 100. When the first joint 241 and the second joint 242 are separated, the threaded rod 244 can be rotated by the knob 246. The threaded rod 244 is threadedly connected to the other side of the fertilizer box 100. When the threaded rod 244 rotates, it can generate axial displacement, thereby driving the fertilizer discharge shaft 230 to move axially, and thus changing the axial position of the rotating block 220. When the first joint 241 and the second joint 242 are engaged, the threaded rod 244, the first joint 241, the second joint 242, and the knob 246 constitute a moving whole, rotating together with the fertilizer discharge shaft 230 under the drive of the drive mechanism.

[0032] Furthermore, the first joint 241 and the second joint 242 each have engaging teeth at their engagement points. These teeth engage and lock, restricting the axial rotation of the first joint 241 and the second joint 242 around the threaded rod 244. However, the second joint 242 can move axially along the threaded rod 244 under external force. The engaging teeth structure provides a superior fit, ensuring structural stability and strength. It should be noted that, besides the engaging teeth structure, other structures can also be used to limit relative rotation. For example, a pin can be provided on the engagement surface of the second joint 242, while a corresponding pin hole can be provided on the engagement surface of the first joint 241. The pin is inserted into the pin hole to prevent rotation.

[0033] To ensure precise application of fertilizer to the soil and prevent fertilizer spillage, in some implementations, the outlet is connected to a fertilizer application pipe that extends towards the ground. The fertilizer can fall along the path of the fertilizer application pipe and be applied to the soil from the outlet, enabling point-to-point fertilization, reducing fertilizer waste, and improving fertilization efficiency.

[0034] In actual planting work, it is sometimes necessary to apply different fertilizers to the soil, such as chemical fertilizers and farmyard manure. Chemical fertilizers and farmyard manure usually need to be separated. Therefore, in some implementation examples, such as... Figure 6 As shown, the fertilizer bin 100 has a partition 130 inside, which divides the inside of the fertilizer bin 100 into a first fertilization area 110 and a second fertilization area 120. The bottom of the first fertilization area 110 and the second fertilization area 120 are respectively provided with a fertilizer outlet and a fertilizer dispensing device 200. The first fertilization area 110 and the second fertilization area 120 can hold different fertilizers to meet different fertilization needs. The fertilizer dispensing shafts 230 of the first fertilization area 110 and the second fertilization area 120 are connected by a synchronization component. After one fertilizer dispensing shaft 230 is connected to the drive mechanism, it can drive the other fertilizer dispensing shaft 230 to rotate together, so that the first fertilization area 110 and the second fertilization area 120 fertilize synchronously. Specifically, the ground wheel 400 transmits power to one fertilizer dispensing shaft 230 through a transmission component to make it rotate, and transmits power to the other fertilizer dispensing shaft 230 through the synchronization component to make it rotate synchronously. It is understandable that the synchronization component can be a timing belt and pulley assembly, or a timing chain and sprocket assembly structure.
