Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery chassis technology, specifically a lifting spiral trenching and fertilizing mechanism. Background Technology

[0002] In horticultural production such as tea, mulberry, and fruit, fertilization is a labor-intensive task that is difficult to control precisely and requires high physical strength, making mechanized fertilization an urgent need. Currently, although various types of fertilization machinery are produced to meet the needs of different production processes, such as chain-type trenching fertilizer applicators, these machines all suffer from drawbacks such as being bulky, having complex structures, and being inconvenient to use. Furthermore, trenching requires turning over the soil and then backfilling it, which is time-consuming, labor-intensive, and represents an inefficient production process.

[0003] For example, our company's authorized announcement number CN109874427B describes a spiral fertilizer applicator suitable for side-applying operations on tea and fruit trees. It consists of three parts: a fertilizer hopper, a frame, and a spiral fertilizer applicator. The spiral fertilizer applicator comprises a transmission box and a spiral fertilizer cylinder that can rotate relative to the transmission box. The spiral fertilizer cylinder contains a spiral hinge cage. The transmission box uses a two-stage reduction gear system (bevel gear and reduction gear) to drive the spiral fertilizer cylinder and spiral hinge cage to rotate in opposite directions, respectively, via the reduction gear and sprocket. An automatic power separation device is also provided between the tilting transmission box and the fertilizer conveyor chain, reducing fertilizer waste and broadening its applicability.

[0004] However, this mechanism has the following drawbacks: First, it cannot work independently and needs to be used with a matching tractor, which is bulky and inconvenient to use; second, the auger fertilizer applicator cannot be moved up and down to adjust the depth of the trench. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting spiral trenching and fertilizing mechanism to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting spiral trenching fertilization mechanism, comprising a fertilizer box 7, a spiral trenching box body 15, and a spiral trenching fertilization bucket 16, wherein the spiral trenching fertilization bucket 16 is located below the spiral trenching box body 15. The spiral trenching box body 15 has a conveying groove 14 of the same width as the fertilizer box 7 fixed at its top and located directly below the top of the fertilizer box 7. Both sides of the conveying groove 14 are provided with a shaft 3 and a conveying hinge 22 wound around the shaft 3. The spiral trenching box body 15 is fixed on a linear guide slider and can freely lift and lower. The input shaft 17 is connected to the drive motor 1 via a telescopic universal coupling 2. The drive motor 1 transmits power again to the feeding hinge 21 and the conveying hinge 22 via a sprocket and chain mechanism.

[0007] Furthermore, the sprocket and chain mechanism includes a right-angle gearbox 10 fixed above the conveying trough 14, a shaft 13 supported by bearings on the front side of the conveying trough 14, and a drive sprocket 18 mounted on the input shaft 17. A transition shaft 5 passes through the right-angle gearbox 10. A passive sprocket 8 connected to the drive sprocket 18 via a chain is mounted on the transition shaft 5. The transition shaft 5 transmits power to the feeding auger 21 and the shaft 11 via two pairs of bevel gears. A drive sprocket 20 is mounted on the shaft 11. Power is transmitted to the passive sprocket 19 on the shaft 13 via a chain. Then, the passive sprockets 12 on both sides of the shaft 13 transmit power to the passive sprocket 4 on the shaft 13 via a chain, ultimately driving the conveying auger 22 to rotate.

[0008] Furthermore, a flexible hose 9 is provided between the conveying trough 14 and the fertilizer box 7 to prevent fertilizer from spilling out.

[0009] Furthermore, both sides of the fertilizer box 7 are equipped with feeding hinges 23, and each is driven by a separate conveying motor 6.

[0010] This utility model has the following advantages: First, it is equipped with a separate drive motor, which can be installed on any chassis to realize automatic trenching and fertilization; second, the spiral fertilizer applicator can move up and down freely, and is equipped with a feeding auger, a conveying auger, and a feeding auger, which avoids fertilizer blockage and improves fertilization efficiency.

[0015] A lifting spiral trenching fertilization mechanism includes a fertilizer box 7, a spiral trenching box body 15, and a spiral trenching fertilization bucket 16, with the spiral trenching fertilization bucket 16 located below the spiral trenching box body 15.

[0016] The spiral trenching fertilizer bucket 16 can be fixedly connected to the linear guide slider, allowing for free lifting and lowering. The input shaft 17 of the spiral trenching fertilizer bucket 16 is equipped with an active sprocket 18, and the input shaft 17 is connected to the drive motor 1 through a telescopic universal coupling 2.

[0017] The top of the spiral trench box 15 is fixed with a conveying trough 14 of the same width as the fertilizer box 7 and located directly below the top of the fertilizer box 7. A telescopic hose 9 is also provided between the conveying trough 14 and the fertilizer box 7 to prevent fertilizer spillage. Both sides of the conveying trough 14 are provided with shaft 3 and conveying hinges 22 wound on shaft 3. The drive motor 1 transmits power to the feeding hinges 21 and the conveying hinges 22 through a sprocket and chain mechanism.

[0018] The sprocket and chain mechanism includes a right-angle gearbox 10 fixed above the conveying trough 14 and a shaft 13 supported by bearings on the front side of the conveying trough 14. The right-angle gearbox 10 contains two sets of bevel gears. A transition shaft 5 passes through the right-angle gearbox 10 and is connected to the bevel gears. The transition shaft 5 is equipped with a passive sprocket 8 connected to the drive sprocket 18 via a chain. After the drive motor 1 transmits power to the transition shaft 5, the transition shaft 5 transmits power to the feeding auger 21 and the shaft 11 via the right-angle gearbox 10. The feeding auger 21 is coaxial with the spiral ditching fertilizer bucket 16. The shaft 11 is equipped with a drive sprocket 20, which transmits power to the passive sprocket 19 on the shaft 13 via a chain. Then, the passive sprockets 12 on both sides of the shaft 13 transmit power to the passive sprocket 4 on the shaft 3 via a chain, ultimately driving the conveying auger 22 to rotate.

[0019] Both sides of the fertilizer box 7 are equipped with feeding hinges 23, each driven by a separate conveying motor 6. This allows the fertilizer in the fertilizer box 7 to be continuously stirred and fed into the conveying trough 14. Then, the conveying hinges 22 feed the fertilizer into the feeding hinges 21. The fertilizer enters the ground along with the feeding hinges 21 and the spiral trenching fertilizer bucket 16, realizing trenching fertilization.
