Description

Technical Field

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

[0002] Trenching is a common and important procedure in landscaping construction, mainly used for laying irrigation pipes and digging planting trenches when planting seedlings. Currently, widely used trenching equipment includes large trenchers and small backpack trenchers. Among them, backpack trenchers are particularly widely used in trenching operations in narrow green areas (such as flowerbeds in parks and green belts in residential areas) due to their small size, light weight, and flexible operation.

[0003] However, existing backpack trenchers typically have fixed-length control levers without any support components. Operators must grip the levers tightly with both hands to control the trenching direction and depth. Due to the lack of support, to ensure stable operation and consistent trenching depth, operators must constantly bend over significantly, maintaining a specific angle between their body and the levers to apply force. This method not only leads to rapid fatigue of the operator's lower back and back muscles, but prolonged operation can also easily cause occupational diseases such as lumbar muscle strain and lumbar disc herniation, seriously affecting the operator's health.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a trenching device for greening construction to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a trenching device for greening construction, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A trenching device for greening construction includes a backpack trencher. The backpack trencher includes a control lever with a fixing strip fixedly connected to its bottom end. A groove is formed on the fixing strip, and a slider is slidably connected within the groove. A motor is fixedly connected to one side of the inner wall of the groove, and a threaded shaft is fixedly connected to the drive end of the motor. The other end of the threaded shaft is rotatably connected to the inner wall of the groove and threadedly connected to the slider. A fixing ring is slidably sleeved on the outer wall of the control lever, and a concave plate is slidably sleeved on the outer wall of the fixing strip. The concave plate is fixedly connected to the fixing ring, and its bottom end is fixedly connected to the slider. Support frames are fixedly connected to both sides of the outer wall of the concave plate, and support wheels are rotatably connected to each support frame. A retaining plate is also fixedly connected to the side of the control lever where the fixing strip is located. A handrail is also provided on the control lever.

[0008] In a further technical solution, the fixing ring and the concave plate are integrally formed structures.

[0009] In a further technical solution, the retaining plate is in the shape of a herringbone.

[0010] In a further technical solution, the control lever is provided with scale lines along its axial direction.

[0011] In a further technical solution, a start button is provided on the joystick, and the start button is electrically connected to the motor.

[0012] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0013] 1. Trenching is performed using a backpack trencher. By controlling the rotation of the motor drive end, the motor drives the threaded shaft to rotate. Then, the threaded shaft drives the slider to slide along the inner wall of the trough. Next, the slider drives the concave plate to move, and the concave plate drives the support frame and support wheel to move. The position of the support wheel on the control lever can be adjusted so that when the support wheel contacts the ground, the control lever can be kept at an angle suitable for the operator. The backpack trencher can be stably controlled without the operator having to bend over significantly. This effectively reduces the stress on the operator's waist and back muscles, reduces labor intensity, avoids occupational diseases caused by prolonged bending over, and protects the operator's health.

[0014] 2. The control lever has scale lines along its axis, which not only helps operators intuitively grasp the current position of the support wheel on the control lever, but also allows operators to record the appropriate scale for their height. When using it later, they can directly adjust to that position, effectively reducing the adaptation time for operators of different heights and significantly improving the versatility and ease of use of the device.

[0020] 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 only used to explain this utility model and are not intended to limit this utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figures 1-3 As shown, this utility model embodiment provides a trenching device for greening construction, including a backpack trencher 1. The backpack trencher 1 includes a control lever 14, with a fixing strip 2 fixedly connected to the bottom end of the control lever 14. A groove 3 is provided on the fixing strip 2, and a slider 6 is slidably connected in the groove 3. A motor 5 is fixedly connected to one side of the inner wall of the groove 3, and a threaded shaft 4 is fixedly connected to the drive end of the motor 5. The other end of the threaded shaft 4 is rotatably connected to the inner wall of the groove 3. 4 is threadedly connected to slider 6. A fixing ring 7 is slidably sleeved on the outer wall of the control lever 14. A concave plate 8 is slidably sleeved on the outer wall of the fixing strip 2. The concave plate 8 is fixedly connected to the fixing ring 7, and the inner bottom end of the concave plate 8 is fixedly connected to slider 6. Support frames 10 are fixedly connected to both sides of the outer wall of the concave plate 8. Support wheels 11 are rotatably connected to each support frame 10. A retaining plate 9 is also fixedly connected to one side of the control lever 14 where the fixing strip 2 is located. A handrail 12 is also provided on the control lever 14.

[0023] Furthermore, the fixing ring 7 and the concave plate 8 are integrally formed structures.

[0024] Furthermore, the retaining plate 9 is herringbone shaped, which facilitates the dispersion of soil splashed onto the retaining plate 9 to both sides.

[0025] Furthermore, the control lever 14 is provided with scale lines along its axial direction (not shown in the figure), which not only helps the operator to intuitively grasp the current position of the support wheel 11 on the control lever 14, but also allows the operator to record the appropriate scale for their height. The operator can directly adjust to that position the next time they use the device without repeated trial and error. This makes it easy for operators of different heights to quickly find the appropriate support position, significantly improving the versatility and ease of use of the device.

[0026] Furthermore, the joystick 14 is equipped with a start button 13, which is electrically connected to the motor 5, so that the motor 5 can be started with one button. When the drive end of the motor 5 needs to rotate, the start button 13 is pressed and held. When the drive end of the motor 5 needs to be stationary, the start button 13 is released.

[0027] In this embodiment of the invention, trenching is performed using a backpack trencher 1. The drive end of the motor 5 is controlled to rotate, which in turn drives the threaded shaft 4 to rotate. The threaded shaft 4 then drives the slider 6 to slide along the inner wall of the groove 3. The slider 6 then moves the concave plate 8, which in turn moves the support frame 10 and the support wheel 11. This allows adjustment of the position of the support wheel 11 on the control lever 14, ensuring that when the support wheel 11 contacts the ground, the control lever 14 remains at an angle suitable for the operator, allowing for stable control of the backpack trencher without requiring the operator to bend over significantly. The negative-type trencher 1 effectively reduces the stress on the waist and back muscles of the operator, lowers labor intensity, avoids occupational diseases caused by prolonged bending work, and protects the health of the operator. The scale lines set along the axis of the control lever 14 not only help the operator intuitively grasp the current position of the support wheel 11 on the control lever 14, but also allow the operator to record the appropriate scale for their height. In subsequent use, the operator can directly adjust to that position, effectively reducing the adaptation time for operators of different heights and significantly improving the versatility and ease of use of the device.

[0028] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
