Description

Technical Field

[0001] This utility model relates to the field of walnut planting, and in particular to a walnut planting hole-digging machine. Background Technology

[0002] Walnuts are the fruit of a deciduous tree belonging to the genus Juglans in the family Juglandaceae. They have a fleshy outer shell that splits open when ripe, revealing a hard inner shell encasing the kernel. Walnuts are extremely nutritious, rich in unsaturated fatty acids, high-quality protein, various vitamins and minerals, and also contain some dietary fiber.

[0003] To ensure the healthy growth and high yield of walnut trees, planting pits must be dug. Digging pits loosens the soil, improving aeration and water permeability, creating a suitable environment for the roots, facilitating fertilization, providing nutrients, guiding the roots to extend fully, enhancing the trees' drought and wind resistance, and effectively regulating soil moisture to meet the walnut trees' needs for space and water.

[0004] Because soil tends to become sticky after absorbing water, some soil will stick to the surface of the digging equipment during the digging process. Therefore, when large-scale and multiple diggings are required, the efficiency will be low in the later stages of digging due to the soil sticking to the surface of the digging tools. To solve this problem, a walnut planting digging machine is proposed. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 2This utility model provides an embodiment of a walnut planting hole-digging machine, including a planting vehicle 1, which is a tractor. The type of planting vehicle 1 ensures that it can move easily in the field. A mounting frame 2 is provided on the rear side of the planting vehicle 1, and a support wheel 3 is provided at the lower end of the mounting frame 2. The support wheel 3 is used to support the rear of the mounting frame 2. A hole-digging device 4 is provided on the inner side of the mounting frame 2. The planting vehicle 1 is used to carry the hole-digging device 4 to move, so as to achieve the effect of digging holes in the soil at different locations.

[0035] Reference Figure 2 and Figure 3 The grooving device 4 includes a rotating wheel 41, which is cylindrical in shape. The outer wall of the rotating wheel 41 and the inner side of the mounting frame 2 are jointly provided with a drive assembly 42. The drive assembly 42 includes a motor 421, whose outer wall is fixedly connected to the outer wall of the mounting frame 2. The output shaft of the motor 421 passes through the inner wall of the mounting frame 2. A gear 422 is fixedly connected to the output shaft of the motor 421. The gear 422 is coaxial with the output shaft of the motor 421. A gear 423 is fixedly connected to the outer wall of the rotating wheel 41. The rotating wheel 41 and the gear 423 are coaxial, and the gear 422 meshes with the gear 423.

[0036] Reference Figures 4-6 A pneumatic rod 43 is slidably connected through the inner wall of the rotating wheel 41. A baffle with the same curvature as the inner circumference of the rotating wheel 41 is provided on the outer wall of the pneumatic rod 43. The baffle limits the movement of the pneumatic rod 43, restricting its outward movement. A hole-digging shovel 44 is fixedly connected to the end of the pneumatic rod 43 away from the axis of the rotating wheel 41. The hole-digging shovel 44 is used to dig holes for planting walnuts. A push rod 45 is piston-connected to the inner wall of the pneumatic rod 43. A protrusion that fits against the inner wall of the pneumatic rod 43 is provided on the outer wall of the push rod 45. A bulldozer plate 46 is fixedly connected to the end of the push rod 45 away from the axis of the rotating wheel 41. The bulldozer plate 46 is used to push out the soil adhering to the inside of the hole-digging shovel 44.

[0037] Reference Figures 4-6A control component 47 is provided on the inner side of the rotating wheel 41. The control component 47 includes a fixed rod 471, which is coaxially arranged with the rotating wheel 41. The outer wall of the fixed rod 471 penetrates the inner wall of the rotating wheel 41 and is fixedly connected to the inner wall of the mounting bracket 2. The rotating wheel 41 can rotate relative to the fixed rod 471. A control wheel 472 is fixedly connected to the outer wall of the fixed rod 471. The control wheel 472 is circular in shape, and its side wall has an arc-shaped groove. The groove ensures that the distance from the outer surface of the control wheel 472 to its axis is not consistent at different positions. A limit groove 473 is provided on the outer wall of the control wheel 472. The shape of the limit groove 473 is consistent with the outer curved surface shape of the control wheel 472. The cross-sectional shape of the limit groove 473 is a circle and a rectangle. A positioning ball 474 is provided inside the limit groove 473. The diameter of the positioning ball 474 is consistent with the diameter of the circular area of ​​the limit groove 473. A control rod 475 is fixedly connected to the side away from the center of the control wheel 472. The diameter of the positioning ball 474 is larger than the diameter of the control rod 475 near the fixed rod 471. By setting the diameter comparison, it is ensured that the positioning ball 474 can be stuck inside the limiting groove 473 by its diameter and will not fall out of the limiting groove 473. The control rod 475 is composed of two cylinders, and the diameter of the control rod 475 near the fixed rod 471 is smaller than the diameter of the side away from the fixed rod 471. By setting the smaller side, it is ensured that the positioning ball 474 can be installed inside the limiting groove 473 by its diameter and will not fall out. By setting the larger diameter side, it is ensured that the control rod 475 can be stably stressed. A piston plate 476 is fixedly connected to the end of the control rod 475 away from the positioning ball 474. The outer wall of the piston plate 476 is connected to the inner wall of the pneumatic rod 43, and the outer wall of the piston plate 476 is in contact with the inner wall of the pneumatic rod 43.

[0038] Reference Figures 4-6 A positioning plate 48 is fixedly connected to the inner wall of the pneumatic rod 43. A through hole is provided in the middle of the positioning plate 48. The gas on both sides of the positioning plate 48 can communicate with each other through the through hole. The side of the positioning plate 48 near the fixed rod 471 is elastically connected to the side of the piston plate 476 away from the control rod 475 by a spring 49. One end of the spring 49 is fixedly connected to the side of the positioning plate 48 near the fixed rod 471, and the other end of the spring 49 is fixedly connected to the end of the piston plate 476 away from the control rod 475. The elastic force of the spring 49 is greater than the friction between the outer wall of the pneumatic rod 43 and the inner wall of the rotating wheel 41.

[0039] Working principle: When in use, the motor 421 starts, which drives the first gear 422 to rotate. When the first gear 422 rotates, it drives the second gear 423 to rotate, which in turn drives the rotating wheel 41 to rotate.

[0040] As the rotating wheel 41 rotates, it drives the pneumatic rod 43 to rotate around its axis, which in turn drives the hole-digging shovel 44 to rotate around the axis of the rotating wheel 41. This causes the hole-digging shovel 44 to come into contact with the soil during rotation and scoop up the soil, thus achieving the effect of digging a hole.

[0041] At the same time, while the rotating wheel 41 drives the pneumatic rod 43 to rotate, the pneumatic rod 43 also drives the control rod 475 and the positioning ball 474 to rotate around the axis of the rotating wheel 41.

[0042] When the positioning ball 474 and the control lever 475 are at a position far from the axis of the fixed lever 471 on the control wheel 472, the control lever 475 moves away from the fixed lever 471 under the squeezing action of the control wheel 472.

[0043] Because a spring 49 applies elastic force to the control lever 475 and the positioning plate 48, and this elastic force is greater than the frictional force between the pneumatic rod 43 and the rotating wheel 41, the control lever 475 first drives the pneumatic rod 43 to move outward synchronously with it.

[0044] When the baffle outside the pneumatic rod 43 contacts the inner circumference of the wheel 41, the pneumatic rod 43 cannot move outward any further. Therefore, the control lever 475 continues to be stressed and moves in the direction of entering the pneumatic rod 43, thereby increasing the air pressure inside the pneumatic rod 43. As a result, the push rod 45 moves outward under the action of air pressure and pushes the bulldozer plate 46, thereby causing the bulldozer plate 46 to move outward and push out the soil inside the hole-digging shovel 44. This ensures that when the hole-digging shovel 44 digs again, the hole-digging effect will not be affected by the sticky soil inside.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
