Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a planetary gear type orchard ditcher transmission structure. Background Technology

[0002] An orchard ditcher is an agricultural machine specifically designed for orchard environments. Its main function is to perform ditching operations in orchards to facilitate fertilization, drainage, irrigation, or pipeline laying. The transmission structure of an orchard ditcher is a series of mechanical components and connections that transmit power from a power source (such as an engine or electric motor) to the working parts of the ditcher (such as the ditching cutter shaft). This structure is crucial to the performance and efficiency of the orchard ditcher, as it determines the efficiency and stability of power transmission.

[0003] The existing transmission structure of orchard trenchers often results in uneven force on the digging claws during digging, which increases the impact and wear on the digging claws, shortens their service life, and increases the maintenance cost of the equipment. In addition, the digging claws cannot make good contact with the soil during digging, and the limited contact area with the soil is not conducive to concentrating the digging force on the soil, thus reducing digging efficiency.

[0004] Therefore, it is necessary to propose a planetary gear type transmission structure for orchard trenchers to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a planetary gear type orchard ditcher transmission structure to solve the problems of uneven force on the digging claw during the digging process, which increases the impact and wear on the digging claw, shortens the service life of the digging claw, increases the maintenance cost of the equipment, and the fact that the digging claw cannot fit well with the soil during the digging process, resulting in a limited contact area with the soil, which is not conducive to concentrating the digging force on the soil and reducing the digging efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a planetary gear type orchard ditching machine transmission structure, including two mounting frames, with through holes in the middle of the two mounting frames, and three small gears evenly and movably arranged in a ring inside each through hole, with a rotating rod fixedly connected to the middle of the small gears;

[0007] A disc is fixedly connected to the end of the rotating rod. Multiple digging claws are uniformly and fixedly installed in a ring around the outer circumference of the disc. The digging claws are arc-shaped, and multiple grooves are formed on the side wall of the digging claws away from the disc.

[0008] Preferably, the claw is bent toward the side away from the groove.

[0009] Preferably, a large gear is rotatably disposed in the middle of the through hole, and a toothed ring is fixedly connected to the side wall of the through hole. The toothed ring and the large gear located on one side are both meshed with the corresponding small gear.

[0010] Preferably, each of the two mounting brackets is fixedly connected to a cross body on one side close to each other, and a ring is fixedly connected to the side of the cross body close to the mounting bracket. The tops of the three rotating rods on one side pass through the corresponding pinions and are movably connected to the corresponding rings.

[0011] Preferably, each of the two cross bodies is provided with a second crown gear on one side close to each other, and a rotating shaft is fixedly connected to the middle of the second crown gear. The rotating shaft passes through the corresponding cross body and is fixedly connected to the corresponding large gear.

[0012] Preferably, a connecting gear is provided between the two mounting brackets, and a first crown gear is fixedly connected to both sides of the connecting gear, and the two first crown gears are respectively meshed with the corresponding second crown gear.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, the bending design of the digging claw and groove can distribute the force during the digging process, reduce the impact and wear on the digging claw and groove, help extend the service life of the digging claw, reduce the maintenance cost of the equipment, and the design of the digging claw and groove can fit more closely to the soil during digging, increasing the contact area with the soil, which is conducive to concentrating the digging force on the soil and improving the digging efficiency.

[0015] 2. The arc-shaped design of the digging claw minimizes soil disturbance during excavation, which helps maintain soil looseness and aeration. At the same time, the grooves make it easier to peel off the soil during excavation, reducing soil residue and accumulation, and facilitating more effective cutting into the soil, ensuring that the excavated trenches are more regular and neat.

[0016] 3. In this utility model, the cooperation of the disc, the digging claw and the groove, and the digging are carried out by rotation and revolution, which results in high digging efficiency and good quality, reduces the amount of manual trimming and reduces labor intensity.

[0017] 4. In this utility model, the digging claw and groove cooperate with the components to simulate the digging behavior and mechanism of a mole. It adopts the principles of bionics and a composite motion mode to drive the trencher to perform complex movements, complete the continuous digging of the soil, reduce the pauses in the digging process, and improve the digging efficiency.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model, and should not be construed as limiting this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the description of this utility model, it should be understood that the terminology used is for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] This invention addresses the problems of uneven force distribution on the digging claw during excavation, which increases impact and wear, shortens the claw's lifespan, and raises equipment maintenance costs. Furthermore, it solves the problem that the claw cannot effectively contact the soil during excavation, resulting in a limited contact area and hindering the concentration of digging force, thus reducing excavation efficiency. The invention provides a solution such as… Figures 1-3 The transmission structure of a planetary gear type orchard ditcher shown includes two mounting frames 1. Each mounting frame 1 has a through hole 11 in its center. Three small gears 14 are evenly and dynamically arranged in a ring inside each through hole 11. A rotating rod 2 is fixedly connected to the center of each small gear 14. When using the device, it is installed at the location of use. Rotating the small gears 14 causes them to revolve along the inner wall of the through hole 11. Simultaneously, the small gears 14 rotate on their own axis, which in turn drives the rotating rod 2 to rotate.

[0027] It should be noted that a disc 21 is fixedly connected to the end of the rotating rod 2. Multiple digging claws 22 are uniformly fixedly installed in a ring around the outer circumference of the disc 21. The digging claws 22 are arc-shaped, and multiple grooves 23 are opened on the side wall of the end of the digging claws 22 away from the disc 21. The rotation of the rotating rod 2 drives the disc 21 to rotate. The disc 21 revolves around the inner wall of the through hole 11 and also rotates on its own axis. The rotation of the disc 21 drives the digging claws 22 and grooves 23 on it to rotate. The digging claws 22 and grooves 23 carry out the digging work of the orchard.

[0028] By cooperating with the digging claw 22 and groove 23, the digging behavior and mechanism of a mole are simulated. The bionic principle and composite motion mode are adopted to drive the trencher to perform complex movements, complete the continuous digging of the soil, reduce the pauses in the digging process, and improve the digging efficiency.

[0029] Furthermore, the digging claw 22 bends away from the groove 23. The arc shape of the digging claw 22 and its bending away from the groove 23 can distribute the force during digging, reducing the impact and wear on the digging claw 22 and the groove 23, which helps to extend the service life of the digging claw 22 and reduce the maintenance cost of the equipment. In addition, the design of the digging claw 22 and the groove 23 allows them to fit more closely to the soil during digging, increasing the contact area with the soil and making it easier to concentrate the digging force on the soil, thus improving digging efficiency.

[0030] Meanwhile, the arc-shaped design of the digging claw 22 minimizes soil disturbance during excavation, which helps maintain soil looseness and aeration. At the same time, the groove 23 makes it easier to peel off the soil during excavation, reducing soil residue and accumulation, and facilitating more effective cutting into the soil, ensuring that the excavated trench is more regular and neat.

[0031] The combination of the disc 21, the digging claw 22, and the groove 23 allows for excavation through rotation and revolution, resulting in high excavation efficiency and quality. This reduces the amount of manual finishing work and lowers labor intensity.

[0032] In this utility model, two mounting brackets 1 are fixedly connected to a cross body 4 on one side close to each other. A ring 41 is fixedly connected to the side of the cross body 4 close to the mounting bracket 1. The top ends of three rotating rods 2 located on one side pass through the corresponding pinion 14 and are movably connected to the corresponding ring 41. The ring 41 helps the rotating rods 2 to rotate and move. The ring 41 is installed on one side of the cross body 4.

[0033] In this utility model, a connecting gear 3 is provided between the two mounting brackets 1. A first crown gear 31 is fixedly connected to both sides of the connecting gear 3. The two first crown gears 31 are respectively meshed with the corresponding second crown gears 43. When the device is installed at the place of use, the device can rotate and dig through the connecting gear 3 and the first crown gears 31. The transmission structure drives the connecting gear 3 to rotate, the rotation of the connecting gear 3 drives the first crown gear 31 to rotate, and the rotation of the first crown gear 31 drives the corresponding second crown gear 43 to rotate. The transmission structure is the structure on the trencher, which is a mature technology in the prior art, and will not be described in detail here.

[0034] It should be noted that each of the two cross bodies 4 is provided with a second crown gear 43 on one side close to each other. A rotating shaft 42 is fixedly connected to the middle of the second crown gear 43. The rotating shaft 42 passes through the corresponding cross body 4 and is fixedly connected to the corresponding large gear 13. The rotation of the second crown gear 43 drives the rotating shaft 42 to rotate, and the rotation of the rotating shaft 42 drives the corresponding large gear 13 to rotate.

[0035] It should also be noted that a large gear 13 is rotatably mounted in the middle of the through hole 11, and a toothed ring 12 is fixedly connected to the side wall of the through hole 11. The toothed ring 12 and the large gear 13 on one side are meshed with the corresponding small gear 14. When in use, rotating the large gear 13 and the toothed ring 12 causes the small gear 14 to rotate on its own axis while revolving around the central axis, which facilitates the completion of subsequent excavation work.
