Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a hole-fertilizing type soil covering mechanism suitable for fertilizing in orchards. Background Art

[0002] The fruit industry is developing rapidly at an unprecedented pace, but with the aging of the population, labor costs are increasingly becoming the main factor restricting the development of the fruit industry.

[0003] During the growth of fruit trees, the application of organic fertilizer to fruit trees not only affects the taste and quality of the fruit, but also has a huge impact on the soil compaction and soil ecosystem stability of the orchard. At present, the best way to apply organic fertilizer is hole application, and the soil covering mechanism is an important part of the hole application machine.

[0004] The function of the soil covering mechanism is mainly to cover the hole application holes with soil after the hole application machine has achieved deep hole application. In order to improve the utilization efficiency of organic fertilizer and prevent the loss of organic fertilizer during rain, it is necessary to cover the hole application holes with soil. In addition, after covering the soil, an oxygen-free environment can be created for the organic fertilizer, which is conducive to the slow release of fertilizer and increases the application efficiency of organic fertilizer.

[0005] At present, soil covering operations usually adopt the form of flat-push soil covering operations, for example, application publication number CN117598074A, a crawler-type self-propelled double-row vegetable sowing robot, for example, application publication number CN117598056A, a degraded grassland replanting microbial repair device and method, which adopts a rolling soil covering operation form, and application publication number CN117643215A, a fully automatic sweet potato transplanter with linear seedling supply, which adopts a disc pressure wheel with a scraper.

[0006] However, in an orchard environment, the flat push covering method cannot be used for continuous flat push covering operations when the site is uneven or there are hard obstacles. The orchard terrain is complex and diverse, and the feasibility of flat push covering operations is low. The rolling covering method has a large operating range, and the rolling process can achieve simultaneous operations over a large area. However, the rolling covering method is only for shallow covering, and cannot meet the covering requirements of deep hole application in the orchard. After the rolling covering operation is completed, there are often large hole application holes, which poses a safety hazard. The disc pressure wheel with scraper type is only suitable for covering operations in deep trench soil. In the process of deep hole application in the orchard, the hole application holes cannot be accurately positioned, and the covering operation is difficult and inefficient. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0024] like Figure 1-Figure 3 As shown, a hole-filling covering mechanism suitable for fertilizing orchards includes a chassis 2 and a transition palm 1 rotatably connected to the chassis 2, the chassis 2 is provided with a thrust component 3 for controlling the flipping of the transition palm 1, and the transition palm 1 is provided with a digging component 4 that rotates synchronously with the transition palm 1; the transition palm 1 is provided with a hydraulic component 5 for driving the digging component 4 to move laterally, the transition palm 1 is provided with a slider 7 arranged parallel to the driving direction of the hydraulic component 5, the digging component 4 is connected to a movable guide rod 6 that moves laterally synchronously with the digging component 4 and is sleeved on the slider 7; the movable guide rod 6 is connected to an elastic bearing seat 8, the digging component 4 is provided with a pull rod 9 connected to the elastic bearing seat 8, the pull rod 9 is sleeved with a damping spring 91 for adjusting the scraping force of the digging component 4, and the pull rod 9 is also provided with an adjusting nut 92 for tightening the damping spring 91.

[0025] A rotating shaft 13 is installed on the transition palm 1, and a bearing seat 34 rotatably connected to the rotating shaft 13 is provided on the chassis 2. The chassis 2 forms a rotating secondary structure with the transition palm 1 through the bearing seat 34 and the rotating shaft 13. The bearing seat 34 and the thrust assembly 3 are staggered. The bearing seat 34 is always rotatably connected to the rotating shaft 13, so that the transition palm 1 uses the rotating shaft 13 as the rotating fulcrum and can be flipped under the action of the thrust assembly 3.

[0026] The thrust assembly 3 includes a left thrust cylinder 31 and a right thrust cylinder 32 arranged in parallel. A fixing pin 33 is provided on the chassis 2 and fixedly connected to the left thrust cylinder 31 and the right thrust cylinder 32. The transition palm 1 is respectively provided with a left thrust pin 11 and a right thrust pin 12 which are rotatably connected to the left thrust cylinder 31 and the right thrust cylinder 32.

[0027] The fixing pin 33 is fixedly connected to the ends of the left thrust cylinder 31 and the right thrust cylinder 32, so that under the action of the fixing pin 33, the ends of the left thrust cylinder 31 and the right thrust cylinder 32 are fixedly installed on the chassis 2, and the left thrust pin 11 is connected to the piston section of the left thrust cylinder 31, and similarly, the right thrust pin 12 is also connected to the piston section of the right thrust cylinder 32. During the extension and retraction process of the left thrust cylinder 31 and the right thrust cylinder 32, the extension and retraction of the left thrust cylinder 31 and the right thrust cylinder 32 are achieved through the rotation of the left thrust pin 11 and the right thrust pin 12, driving the transition palm 1 to swing with the rotating shaft 13 as the rotation fulcrum.

[0028] The digging assembly 4 includes a left digging bucket 41 and a right digging bucket 42 located on the same digging plane. The left digging bucket 41 and the right digging bucket 42 both rotate synchronously with the transition palm 1 through the slider 7. The left digging bucket 41 and the right digging bucket 42 are correspondingly connected to two different movable guide rods 6. The two movable guide rods 6 are respectively sleeved on two parallel sliders 7. The left digging bucket 41 and the right digging bucket 42 independently translate under the action of the two movable guide rods 6, and the left digging bucket 41 and the right digging bucket 42 are synchronously flipped under the action of the thrust assembly 3. The left digging bucket 41 and the right digging bucket 42 are flipped under the action of the thrust assembly 3 to perform digging operations.

[0029] The surface of the slider 7 is fixedly connected to the transition palm 1, thereby limiting the slider 7 during movement and preventing the slider 7 from flipping over, thereby limiting the flipping state of the excavation assembly 4, and the moving guide rod 6 is always sleeved on the slider 7. At the same time, the moving guide rod 6 is guided and limited under the action of the slider 7, ensuring that the moving guide rod 6 is always in a transverse state and the state does not change during the transverse movement, thereby realizing stable transverse movement of the excavation assembly 4.

[0030] The hydraulic direction of the hydraulic component 5 is set perpendicular to the thrust direction of the thrust component 3. The thrust component 3 is used to control the flipping of the excavating component 4 in the vertical direction, and the hydraulic component 5 is used to control the movement of the excavating component 4 in the horizontal direction. Combining the hydraulic component 5 and the thrust component 3, the excavating component 4 can be flipped at different horizontal positions to achieve excavation operations.

[0031] The hydraulic assembly 5 includes a left-side moving hydraulic cylinder 51 and a right-side moving hydraulic cylinder 52 which are parallel and have opposite hydraulic directions. The left-side moving hydraulic cylinder 51 and the right-side moving hydraulic cylinder 52 are respectively arranged corresponding to the left excavator bucket 41 and the right-side moving hydraulic cylinder 42. The left-side moving hydraulic cylinder 51 and the right-side moving hydraulic cylinder 52 respectively control the movement of the left-side excavator bucket 41 and the right-side excavator bucket 42, and the left-side moving hydraulic cylinder 51 and the right-side moving hydraulic cylinder 52 are independently controlled. The horizontal positions of the left-side excavator bucket 41 and the right-side excavator bucket 42 are selected and controlled under the action of the left-side moving hydraulic cylinder 51 and the right-side moving hydraulic cylinder 52 according to actual needs.

[0032] A support shaft 43 is provided at the top of the excavating component 4, which is rotatably connected to the elastic bearing seat 8. The pull rod 9 is connected to the bottom of the excavating component 4, and the pull rod 9 is rotatably connected to the excavating component 4. The pull rod 9 is installed on the back of the excavating component 4, and the pull rod 9 supports the back of the excavating component 4. The excavating component 4 is rotatably connected to the elastic bearing seat 8 to cooperate with the setting of the damping spring 91. A threaded section is formed at the end of the pull rod 9, which is threadedly connected to the adjusting nut 92, so that the compression amount of the damping spring 91 can be adjusted by adjusting the position of the adjusting nut 92.

[0033] The support shaft 43 and the pull rod 9 are respectively located at opposite ends of the elastic support 8, and two elastic support seats 8 corresponding to the opposite sides of the excavation component 4 are fixedly installed on the movable guide rod 6.

[0034] During actual use, the chassis 2 is connected to the hole-spreading machine. After the hole-spreading machine completes the hole-spreading operation on the fruit trees, it transmits the hole-spreading position information to the hole-spreading covering mechanism. The left mobile hydraulic cylinder 51 and the right mobile hydraulic cylinder 52 push the left digging bucket 41 and the right digging bucket 42 to the corresponding positions respectively. At this time, the left thrust cylinder 31 and the right thrust cylinder 32 push the overhand palm 1 downward, so that the left digging bucket 41 and the right digging bucket 42 are in close contact with the ground. At this time, the hole-spreading machine moves to bring the soil into the hole-spreading hole. After completing the covering operation, each execution component returns to its original state.

[0035] The double-sided digging bucket form is realized by adopting the left digging bucket 41 and the right digging bucket 42, which can be automatically adjusted according to the position of the hole for application to ensure the accuracy of the soil covering operation. Moreover, during the soil covering operation, the compression amount of the damping spring 91 can be adjusted by adjusting the nut 92 according to the hardness of the soil to ensure the scraping force during the soil covering process. When the hole application machine is installed, the labor input of the orchard management is reduced while performing precise soil covering, thereby further reducing the production cost.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
