Description

Technical Field

[0001] This utility model relates to the field of landscape construction technology, and in particular to a trenching device for landscape construction. Background Technology

[0002] In the field of landscape construction, ditch excavation is a crucial foundational task. Its quality and efficiency directly impact subsequent aspects such as the layout of landscape facilities, the construction of drainage systems, and the planting of vegetation. Properly designed ditches can effectively guide water flow and facilitate pipeline laying, ensuring the normal operation and aesthetic appeal of the landscape. Currently, ditch excavators are widely used in landscape construction ditch excavation due to their high efficiency and labor-saving characteristics. Existing ditch excavators mainly consist of a mobile chassis equipped with ditching blades. Motors and other drives rotate the blades to excavate soil and form ditches.

[0003] However, the trenching cutters of most traditional trenching machines are fixedly mounted on the mechanical structure, and their width is determined at the factory, making it impossible to adjust in real time according to actual construction needs. When encountering situations where trenches of different widths need to be dug, the only way is to dig back and forth multiple times to stack them into a trench of sufficient width, which is inefficient and very inconvenient. Utility Model Content

[0004] In view of this, this utility model proposes a trenching device for garden construction, which aims to solve the problem that the trenching width of existing trenching machines cannot be flexibly adjusted.

[0005] The solution provided by this utility model includes:

[0006] A trenching device for garden construction includes a vehicle body, a trenching mechanism mounted on the vehicle body, and a drive unit for driving the trenching mechanism. The trenching mechanism includes a rotating shaft and a rotating impeller coaxially mounted on the rotating shaft.

[0007] The rotating impeller includes a plurality of sub-impellers arranged axially along the rotating shaft. Each sub-impeller includes a wheel body and a plurality of digging blades disposed on the periphery of the wheel body. The width of the digging blades is greater than the width of the wheel body, and the digging blades on two adjacent sub-impellers overlap at least partially in the axial direction of the rotating shaft.

[0008] The rotating shaft is provided with multiple sets of first connecting parts and second connecting parts for detachable connection with the sub-impeller. The first connecting parts and the second connecting parts are staggered in the axial direction of the rotating shaft and staggered in the circumferential direction so that the digging blades on two adjacent sub-impellers are staggered.

[0009] As a further optional solution, the sub-impeller consists of two half-wheel components;

[0010] The semi-wheel component includes a semi-circular wheel body, with multiple digging blades fixedly disposed on the outer side of the wheel body, and an arc-shaped clamping plate for clamping the rotating shaft fixedly disposed on the inner side of the wheel body. Connecting plates extend from both ends of the arc-shaped clamping plate, and the connecting plates are used for bolting to the first connecting part / second connecting part.

[0011] As a further optional solution, both the first connecting part and the second connecting part include two mounting plates symmetrically arranged on the rotating shaft, and the length direction of the mounting plates is arranged along the radial direction of the rotating shaft;

[0012] The mounting plate of the first connecting part and the mounting plate of the second connecting part have an angle in the circumferential direction.

[0013] As a further optional solution, the multiple digging blades on the sub-impeller are equidistantly distributed in the circumferential direction, and the included angle between two adjacent digging blades is twice the included angle between the mounting plate of the first connecting part and the mounting plate of the second connecting part.

[0014] As a further alternative, a sub-impeller includes eight digging blades, with an included angle of 45° between two adjacent digging blades; the included angle between the mounting plate of the first connecting part and the mounting plate of the second connecting part in the circumferential direction is 22.5°.

[0016] The mounting plate is provided with a second connection hole corresponding to the position of the first connection hole;

[0017] The connecting plates on the two half-wheels are respectively clamped on both sides of the mounting plate and fixed by bolt assembly.

[0018] As a further optional solution, the rotating shaft may have multiple rotating impellers.

[0019] Compared with the prior art, the trenching device for garden construction proposed in this application has at least the following advantages:

[0020] The rotary impeller in this trenching device consists of multiple sub-impellers. When facing the need for trenches of different widths, the number of sub-impellers can be adjusted by installing or removing them, thereby adjusting the overall width of the rotary impeller and thus the trench width, improving the adaptability of the construction. The digging blades on adjacent sub-impellers overlap at least partially in the axial direction of the rotating shaft, ensuring that multiple sub-impellers can work closely together during the trenching process to form a continuous trenching working surface. This allows the rotary impeller to dig a complete trench in one go. Attached Figure Description

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] refer to Figures 1 to 5 An embodiment of this utility model shows a trenching device for garden construction, including a vehicle body 100, a trenching mechanism 200 disposed on the vehicle body 100, and a drive unit 300 for driving the trenching mechanism 200. The trenching mechanism 200 includes a rotating shaft 1 and a rotating impeller 2 coaxially disposed on the rotating shaft 1.

[0034] The rotating impeller 2 includes a plurality of sub-impellers 21 arranged along the axial direction of the rotating shaft 1. Each sub-impeller 21 includes a wheel body 2111 and a plurality of digging blades 2112 disposed on the outer periphery of the wheel body 2111. The width of the digging blades 2112 is greater than the width of the wheel body 2111, and the digging blades 2112 on two adjacent sub-impellers 21 overlap in at least a portion of the axial direction of the rotating shaft 1.

[0035] The rotating shaft 1 is provided with multiple sets of first connecting parts 11a and second connecting parts 11b for detachable connection with the sub-impeller 21. The first connecting parts 11a and second connecting parts 11b are staggered in the axial direction of the rotating shaft 1 and staggered in the circumferential direction so that the digging blades 2112 on two adjacent sub-impellers 21 are staggered.

[0036] Specifically, such as Figure 2As shown, the rotating impeller 2 is composed of multiple sub-impellers 21. The sub-impellers 21 are detachable from the rotating shaft 1. By increasing or decreasing the number of sub-impellers 21, the overall width of the rotating impeller 2 can be adjusted, thereby adjusting the trench width.

[0037] Among them, such as Figure 4 As shown, the digging blades 2112 on adjacent sub-impellers 21 overlap at least partially in the axial direction of the rotating shaft 1, allowing multiple sub-impellers 21 to work closely together during trenching to form a continuous trenching working surface, enabling the rotating impeller 2 to excavate a complete trench in one go. Since the digging blades 2112 on adjacent sub-impellers 21 overlap at least partially in the axial direction, to avoid interference between the digging blades 2112 in the axial direction, this embodiment staggers the digging blades 2112 on adjacent sub-impellers 21 in the circumferential direction to ensure structural stability.

[0038] In some embodiments, to facilitate the mounting and dismounting of the impeller 21 on the rotating shaft 1, such as... Figure 3 and Figure 5 As shown, the impeller 21 is composed of two half-wheel parts 211; each half-wheel part 211 includes a semi-circular wheel body 2111, with multiple digging blades 2112 fixedly arranged on the outer side of the wheel body 2111, and an arc-shaped clamping plate 2113 for clamping the rotating shaft 1 fixedly arranged on the inner side of the wheel body 2111. Connecting plates 2114 extend from both ends of the arc-shaped clamping plate 2113, and the connecting plates 2114 are used for bolt connection with the first connecting part 11a / second connecting part 11b.

[0039] All the sub-impellers 21 are composed of half-wheel parts 211, that is, the entire rotating impeller 2 is formed by only one type of part, the half-wheel part 211, which is convenient for manufacturing. When installing or disassembling the sub-impellers 21, only the two half-wheel parts 211 need to be installed or disassembled to realize the installation or disassembly of one sub-impeller 21, which is relatively convenient.

[0040] Specifically, in the above scheme, both the first connecting part 11a and the second connecting part 11b include two mounting plates 111 symmetrically arranged on the rotating shaft 1, and the length direction of the mounting plates 111 is arranged radially along the rotating shaft 1; as shown Figure 5 As shown, the mounting plate 111 of the first connecting part 11a and the mounting plate 111 of the second connecting part 11b have an included angle K in the circumferential direction.

[0041] Preferably, the multiple digging blades 2112 on the sub-impeller 21 are equidistantly distributed in the circumferential direction, and the included angle between two adjacent digging blades 2112 is twice the included angle K between the mounting plate 111 of the first connecting part 11a and the mounting plate 111 of the second connecting part 11b. This ensures that the digging blades 2112 on one sub-impeller 21 are located at the center of two digging blades 2112 on another sub-impeller 21, guaranteeing that the structures of adjacent sub-impellers 21 do not interfere with each other. Furthermore, it allows for a more uniform distribution of the digging blades 2112 across the entire rotating impeller 2.

[0042] Specifically, in this embodiment, as follows: Figure 3 and Figure 5 As shown, a sub-impeller 21 includes eight digging blades 2112, and the included angle between two adjacent digging blades 2112 is 45°; the included angle between the mounting plate 111 of the first connecting part 11a and the mounting plate 111 of the second connecting part 11b in the circumferential direction is 22.5°.

[0043] In some embodiments, to ensure a stable connection between the half-wheel component 211 and the rotating shaft 1, such as Figure 2 and Figure 3 As shown, the width of the connecting plate 2114 is greater than the width of the wheel body 2111. The connecting plate 2114 is provided with two first connecting holes 2115, which are symmetrically distributed on both sides of the wheel body 2111. The mounting plate 111 is provided with second connecting holes 112 corresponding to the positions of the first connecting holes 2115. The connecting plates 2114 on the two half-wheels 211 are respectively clamped on both sides of the mounting plate 111 and connected and fixed by bolt assemblies (not shown).

[0044] Thus, the connecting plate 2114 and the mounting plate 111 are connected by two sets of bolt assemblies, making it difficult for the connecting plate 2114 and the mounting plate 111 to loosen; the two sets of bolt assemblies are distributed on both sides of the wheel body 2111, making the impeller 21 more balanced when rotating.

[0045] Based on the adjustable structure of the rotating impeller 2, another embodiment (not shown) is provided, in which multiple rotating impellers 2 are provided on the rotating shaft 1.

[0046] Since the impeller 21 is easy to install and remove on the rotating shaft 1, multiple rotating impellers 2 can be formed on the rotating shaft 1, so that the trenching device can dig multiple trenches at one time, and even multiple trenches with different widths; thus, the adjustable structure of the rotating impeller 2 in this embodiment greatly improves the expandability and adaptability of the trenching device.

[0047] In summary, this application provides a trenching device for garden construction. The rotating impeller 2 in the trenching device is composed of multiple sub-impellers 21. When facing the need for trenches of different widths, the number of sub-impellers 21 can be adjusted by installing or removing the sub-impellers 21, thereby adjusting the overall width of the rotating impeller 2 and thus adjusting the trench width, improving the adaptability of construction. The digging blades 2112 on adjacent sub-impellers 21 overlap at least partially in the axial direction of the rotating shaft 1, ensuring that the multiple sub-impellers 21 can work closely together during the trenching process to form a continuous trenching working surface. This allows the rotating impeller 2 to dig a complete trench in one go.

[0048] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
