Description

Technical Field

[0001] This utility model relates to the field of seedling shovel technology, and in particular to a seedling shovel for forestry planting. Background Technology

[0002] When transplanting seedlings, a seedling shovel can be used to completely dig the seedlings out of the seedbed or nursery. By inserting the shovel into the soil around the seedling roots and then gently prying or cutting, the seedling can be detached from the soil intact with some of its soil ball or root system, reducing damage to the seedling root system and improving the survival rate of the seedlings after transplanting.

[0003] In existing technologies, the shovel heads for forestry planting are mostly fixed to the handles. If either the shovel head or the handle is damaged, it can be difficult to separate the shovel head from the handle for repair or replacement, especially with more secure connections such as welding. This may require specialized tools and techniques, and could even render the entire shovel unusable. This may not meet the user's needs for different angles. Therefore, this paper proposes a shovel for forestry planting. Utility Model Content

[0004] To address the shortcomings of existing technologies, the utility model provides the following technical solution: a seedling-lifting shovel for forestry planting, comprising: a shovel head, with teeth on one side of the top of the shovel head; a horizontal plate fixedly connected to the top of the shovel head; a movable block hinged to the middle of the top of the horizontal plate; a connecting assembly fixedly connected to the top of the movable block; the connecting assembly comprising a first connecting shaft; locking blocks fixedly connected to both sides of the first connecting shaft; a second connecting shaft at the bottom of the first connecting shaft; locking grooves on both sides of the top of the second connecting shaft; and a groove inside the second connecting shaft.

[0005] As an improvement to the above technical solution, a positioning plate is fixedly connected to the top periphery of the first connecting shaft.

[0006] As an improvement to the above technical solution, the positioning plate is provided with a shovel handle inside, and an extension component is hinged to the top of the shovel handle. The extension component includes a round tube, and a threaded rod is threaded to the bottom end of the round tube. A hinge block is connected to the bottom end of the threaded rod.

[0007] As an improvement to the above technical solution, a washer is provided at the bottom end of the threaded rod, and the bottom end of the washer is connected to the top end of the hinge block.

[0008] As an improvement to the above technical solution, a positioning shaft is provided at the junction of the hinge block and the shovel handle, and a soft pad is provided around the positioning shaft.

[0009] As an improvement to the above technical solution, the shovel head is made of carbon steel or wood.

[0010] As an improvement to the above technical solution, a protective film is provided on the surface of both the round tube and the shovel handle.

[0011] The beneficial effects of this utility model are as follows: The shovel head is the main working part of the seedling shovel, used to insert into the soil to dig up seedlings. The toothed marks on one side of its top can increase the friction between the shovel head and the soil during digging, making it easier to cut into harder soil and helping to improve digging efficiency. The movable block can be connected to the shovel head by hinge, thereby achieving a certain degree of movement. When it is necessary to replace the shovel head or shovel handle, the first connecting shaft is rotated so that the locking block can slide inside the groove. When the locking block slides into the locking groove, the first connecting shaft and the second connecting shaft can be pulled to separate the shovel head and the shovel handle, which is convenient for subsequent replacement.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] See appendix Figure 1-4 As shown, to solve the above problems, a seedling-lifting shovel for forestry planting is provided, including: a shovel head 1, with tooth marks 11 on one side of the top of the shovel head 1, a horizontal plate 12 fixedly connected to the top of the shovel head 1, a movable block 13 hinged to the middle of the top of the horizontal plate 12, a connecting component 3 fixedly connected to the top of the movable block 13, the connecting component 3 including a first connecting shaft 31, with locking blocks 32 fixedly connected to both sides of the first connecting shaft 31, a second connecting shaft 33 provided at the bottom of the first connecting shaft 31, slots 34 opened on both sides of the top of the second connecting shaft 33, and a groove 35 opened inside the second connecting shaft 33.

[0023] The shovel head 1 is the main working part of the seedling digging shovel, used to insert into the soil to dig up seedlings. The toothed marks 11 on one side of its top can increase the friction between the shovel head 1 and the soil during digging, making it easier to cut into harder soil and helping to improve digging efficiency. The movable block 13 can be connected to the shovel head 1 by hinge, thereby realizing a certain degree of movement. When it is necessary to replace the shovel head 1 or the shovel handle 14, the first connecting shaft 31 is rotated so that the locking block 32 can slide inside the groove 35. When the locking block 32 slides to the point where it is pulled together with the locking groove 34, the first connecting shaft 31 and the second connecting shaft 33 can be pulled to separate the shovel head 1 and the shovel handle 14 for subsequent replacement.

[0024] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a positioning plate 15 is fixedly connected to the top periphery of the first connecting shaft 31.

[0025] The positioning plate 15 can be used to position other components (such as the shovel handle 14) connected to the first connecting shaft 31, ensuring that these components are installed in the correct position and guaranteeing the accuracy and stability of the connection of each part of the seedling shovel.

[0026] For specific implementation details, please refer to [link / reference]. Figure 1-4Specifically, the positioning plate 15 has a shovel handle 14 inside, and an extension component 2 is hinged to the top of the shovel handle 14. The extension component 2 includes a round tube 21, and a threaded rod 22 is threaded to the bottom of the round tube 21. A hinge block 24 is connected to the bottom of the threaded rod 22.

[0027] In actual forestry planting operations, different terrains, seedling planting depths, and the height and operating habits of operators may require adjustments to the length of the shovel handle 14. By connecting the threaded rod 22 to the bottom of the round tube 21, rotating the threaded rod 22 can adjust its extension length within the round tube 21, thereby changing the length of the entire extension assembly 2. The hinge block 24 connected to the bottom of the threaded rod 22 is hinged to the top of the shovel handle 14, allowing the extension assembly 2 to rotate flexibly relative to the shovel handle 14. This makes it convenient to store the extension assembly 2 when not in use, reducing space occupation.

[0028] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a washer 23 is provided at the bottom end of the threaded rod 22, and the bottom end of the washer 23 is connected to the top end of the hinge block 24.

[0029] By using the shim 23, the contact area between the threaded rod 22 and the hinge block 24 can be increased. This allows the force transmitted from the threaded rod 22 to the hinge block 24 to be distributed more evenly, avoiding excessive local stress on the hinge block 24 due to concentrated force, thereby reducing the possibility of damage to the hinge block 24 and extending its service life.

[0030] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a positioning shaft 25 is provided at the junction of the hinge block 24 and the shovel handle 14, and a soft pad is provided around the positioning shaft 25.

[0031] By using the positioning shaft 25, the connection position of the hinge block 24 and the shovel handle 14 can be precisely defined, ensuring that the two maintain accurate axis of rotation when rotating relative to each other. This makes the connection between the extension component 2 and the shovel handle 14 more stable and reliable, avoiding shaking or displacement, and ensuring the stability and accuracy of the seedling shovel during operation. The soft pad (not shown in the figure) can act as a buffer between the hinge block 24 and the shovel handle 14, reducing the transmission of vibration and impact, reducing wear on the connection parts, extending the service life of the seedling shovel, and also improving the comfort of the operator when holding the shovel handle 14.

[0032] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, the shovel head 1 is made of carbon steel, and the shovel head 1 is made of wood.

[0033] Steel has high strength and hardness, which can withstand the large external forces during the seedling lifting process and is not easily deformed. At the same time, it has good wear resistance, which can maintain the sharpness and shape of the shovel head 1 when digging soil and cutting seedling roots, extending its service life, reducing the frequency of replacing the shovel head 1, and improving work efficiency. The wooden shovel head 1 is relatively light, which is convenient for operators to use for a long time and reduces labor intensity.

[0034] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, the surfaces of the round tube 21 and the shovel handle 14 are covered with a protective film.

[0035] In forestry planting environments, the round tube 21 and the shovel handle 14 may come into contact with moisture, acidic or alkaline substances in the soil, etc. The protective film can isolate them from external corrosive substances, prevent rust and corrosion, and extend their service life.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
