Description

Technical Field

[0001] This utility model relates to agricultural machinery, specifically a large-capacity tracked spiral trenching, fertilizing, and soil-covering integrated machine. 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, a spiral fertilizer applicator, authorized by Yancheng Yanhai Tractor Manufacturing Co., Ltd. (authorization announcement number CN109874427B), suitable for side-operation on tea and fruit trees, 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. A spiral hinge cage is installed inside the spiral fertilizer cylinder. The transmission box uses a two-stage reduction gear and a reduction gear for speed reduction, and the reduction gear and sprocket drive the spiral fertilizer cylinder and spiral hinge cage to rotate in opposite directions respectively. An automatic power separation device is also provided between the tilting transmission box and the fertilizer conveying chain to reduce fertilizer waste and facilitate soil covering, thus broadening its application range.

[0004] However, this mechanism has the following drawbacks: First, it cannot move and 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 technical problem to be solved by this utility model is to provide a large-capacity tracked spiral trenching, fertilizing and soil covering machine that addresses the shortcomings of the existing technology.

[0006] The technical solution of this utility model includes a fertilizer box 17, a trenching fertilizer bucket 20, and a fertilizer hopper 13. The trenching fertilizer bucket 20 is located below the fertilizer box 17, and the fertilizer hopper 13 is fixed above the fertilizer box 17 by a support box 14. The fertilizer box 17 is located at the center of the tracked chassis 1 by a bracket 19. The two sides of the fertilizer box 17 are fixedly connected to the linear rail 3 on the bracket 19 by connecting side plates 16, and the fertilizer box 17 is driven by a hydraulic cylinder 18 to move up and down along the linear rail 3. A handrail 4 and a gasoline engine 5 providing power are provided at the rear of the tracked chassis 1. A symmetrically arranged auxiliary feeding hinge 11 is also provided between the fertilizer box 17 and the fertilizer hopper 13. The hinge 11 is welded to the rotating shaft 7 and driven by an independent motor 6.

[0007] Furthermore, the upper part of the support box 14 is located inside the fertilizer hopper 13, and a stirring rod 10 is also provided between the support boxes 14 and located inside the fertilizer hopper 13. A passive wheel 9 connected to the stirring rod 10 is provided in one of the support boxes 14, and a driving wheel 8 is provided on the rotating shaft 7 on the same side as the passive wheel 9. The passive wheel 9 and the driving wheel 8 are connected by a chain or a synchronous belt.

[0008] Furthermore, a lifting plate 15 is welded between the connecting side plates 16, and the center of the lifting plate 15 is connected to the output end of the hydraulic cylinder 18.

[0009] Compared with the prior art, this utility model has the following advantages: First, it can move and work independently without the need for a tractor, and its size is relatively small and convenient. It can automatically perform three operations at once: spiral trenching, fertilization, and soil covering. Second, it is equipped with a trenching and fertilizing device with a lifting mechanism, which can adjust the trenching and fertilization depth according to needs. Third, it is equipped with an auxiliary feeding and anti-sticking mechanism to prevent fertilizer from sticking together and improve fertilization efficiency. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] This utility model is a large-capacity tracked spiral trenching, fertilizing and covering machine, including a fertilizer box 17, a trenching and fertilizing bucket 20 and a fertilizer hopper 13. The trenching and fertilizing bucket 20 is located below the fertilizer box 17, and the fertilizer hopper 13 is fixed above the fertilizer box 17 by a support box 14.

[0014] The fertilizer box 17 is mounted on the center of the tracked chassis 1 via a bracket 19. The two sides of the fertilizer box 17 are fixedly connected to the linear rail 3 on the bracket 19 via connecting side plates 16. A lifting plate 15 is also welded between the connecting side plates 16. The center of the lifting plate 15 is connected to the output end of the hydraulic cylinder 18. The hydraulic cylinder 18 drives the fertilizer box 17 to move up and down along the linear rail 3. The input shaft in the fertilizer box 17 is connected to the output shaft in the transmission mechanism via a telescopic universal joint 2. The transmission mechanism is driven by a gasoline engine 5.

[0015] A handrail 4 and a gasoline engine 5 providing power are located at the rear of the tracked chassis 1. The gasoline engine 5 provides power to the tracked chassis 1 and the fertilizer box 17. A symmetrically arranged auxiliary feeding hinge 11 is also provided between the fertilizer box 17 and the fertilizer hopper 13. The hinge 11 is welded to the rotating shaft 7 and driven by an independent motor 6. A fertilizer feed inlet 12 that penetrates the top of the fertilizer box 17 is provided between the hinge 11. The fertilizer in the fertilizer hopper 13 is fed into the fertilizer feed inlet 12. The trenching fertilizer bucket 20 performs spiral trenching on the ground and then applies fertilizer. The soil is turned upward under the action of the outer circular hinge of the trenching fertilizer bucket 20, and finally falls automatically under the action of gravity to cover the soil. The three operations of spiral trenching, fertilization and soil covering are realized at one time.

[0016] Meanwhile, to prevent the fertilizer above the fertilizer hopper 13 from sticking together, the upper part of the support box 14 is located inside the fertilizer hopper 13. A stirring rod 10 is also provided between the support boxes 14 and located inside the fertilizer hopper 13. A passive wheel 9 connected to the stirring rod 10 is provided in one of the support boxes 14. A driving wheel 8 is provided on the rotating shaft 7 on the same side as the passive wheel 9. The passive wheel 9 and the driving wheel 8 are connected by a chain or synchronous belt. When the motor 6 rotates, it will drive the rotating shaft 7 to rotate, that is, the hinge 11 and the stirring rod 10 rotate at the same time, respectively stirring and conveying the fertilizer.
