Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trenching machines, and in particular relates to a suspended fixed-distance trenching machine for planting yellow willows in desert areas. Background Technology
[0002] Currently, when manually propagating *Salix matsudana* in desert areas, suspended trenching machines are commonly used. These suspended trenching machines, also known as three-point suspended trenching machines, are suspended from a tractor and raised / lowered via the tractor's hydraulic suspension system. They can be installed when in use and removed when not in use, and can operate on any soil surface. The suspended trenching machine is connected to the wheeled tractor via a three-point suspension and is driven by the tractor's power take-off shaft. Patent application CN202210625307.5 discloses a direct-drive electro-hydraulic suspension system for an electric tractor and its control method, which is used to raise and lower the implement frame.
[0003] However, in desert areas, even when using a suspended trenching machine to create trenches in the sand, manual marking of cutting points along the trenches is still required. This manual marking method has the following problems: First, low marking efficiency: manually pulling measuring ropes or pacing to determine the location is time-consuming and labor-intensive, and is easily affected by wind and sand, causing the markings to shift. Second, large spacing error: the spacing of manual markings fluctuates by more than ±10cm, affecting the uniformity of willow growth and the sand-fixing effect. Third, separation of trenching and marking: after trenching, a second entry into the work area is required for marking, increasing the number of times the tractor rolls over the area, leading to damage to the sand structure. Utility Model Content
[0004] In view of this, the present invention aims to propose a suspended fixed-distance trenching machine for planting yellow willows in desert areas, so as to provide a trenching machine that can simultaneously complete fixed-distance marking during trenching, and achieve low-cost and high-precision marking through mechanical linkage.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A suspended, fixed-distance ditching machine for planting yellow willow in desert areas includes a tractor, a tractor hydraulic suspension system, a implement frame, and a ditching cutter. The tractor is equipped with a tractor hydraulic suspension system for raising and lowering the implement frame. The ditching cutter is mounted on the implement frame. The implement frame also has a fixed-distance device, which includes a fixed-distance wheel, a rotating axle, and a wheel frame. The wheel frame is mounted on the implement frame, and the fixed-distance wheel is mounted on the rotating axle and can rotate around the axle. Both ends of the rotating axle are mounted on the wheel frame. The fixed-distance wheel is located in front of the ditching cutter. The fixed-distance wheel includes a wheel surface, marking rods, a roller, and support rods. A rotating shaft passes through the roller, and both ends of the roller are connected to the wheel surface. The marking rods include multiple rods, which are evenly spaced around the outer edge of the wheel surface. The cross-section of the marking rods is triangular, and its apex extends to the outside of the wheel surface. The support rods include multiple rods, which are connected between the roller and the marking rods.
[0006] Furthermore, the wheel frame includes a support and a crossbeam, with the support connected to both ends of the crossbeam, the pivot connected to the front end of the support, and the crossbeam mounted on the implement frame.
[0007] Furthermore, the bracket is inclined and extends forward of the trenching cutter, and the outer edge of the spacer wheel abuts against the front end of the trenching cutter.
[0008] Furthermore, it also includes a mounting plate, a connecting rod, and a tool holder. The front end of the implement frame is connected to the mounting plate, and the tool holder is set on the mounting plate. The tool holder includes two clamps set on both sides of the trenching cutter. The upper part of the trenching cutter is detachably connected to the clamps through a positioning pin.
[0009] Furthermore, the implement frame includes a tripod, side wing rods, an upper connecting rod, and a lower connecting rod; the side wing rod, upper connecting rod, and lower connecting rod are arranged between the tripod and the mounting plate; the upper connecting rod and the lower connecting rod are respectively connected to the top corner and the bottom edge of the tripod, and the two bottom corners of the tripod are respectively connected to the side wing rod.
[0010] Furthermore, the tractor hydraulic suspension system includes an upper tie rod, a lower tie rod, and a lifting hydraulic cylinder. The upper tie rod is connected to the upper end of the tripod, and the two bottom corners of the tripod are respectively connected to the lower tie rod. The lower tie rod is connected to the lifting hydraulic cylinder.
[0011] Furthermore, the grooving cutter is located at the corresponding position in the middle of the long side of the marking rod.
[0012] Furthermore, a counterweight is also provided on the fixed-distance wheel.
[0013] Compared with existing technologies, the suspended fixed-distance trenching machine for planting yellow willows in desert areas described in this utility model has the following advantages: The suspended fixed-distance ditching machine of this utility model features a ditching blade and a distance-fixing device mounted on the implement frame. A tractor pulls the implement frame to dig trenches, leaving curved grooves in the sandy soil. Simultaneously, the distance-fixing wheel rolls on the sandy ground, leaving groove marks on the marking rod using the apex of the marking rod.

Detailed Implementation
[0016] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] like Figure 1 As shown, a suspended fixed-distance ditching machine for planting yellow willow in desert areas includes a tractor 1, a tractor hydraulic suspension system 2, a implement frame 3, and a ditching bend 4. The tractor 1 is equipped with the tractor hydraulic suspension system 2, which is used to raise and lower the implement frame 3. The implement frame 3 is equipped with the ditching bend 4. The implement frame 3 is also equipped with a fixed-distance device, which includes a fixed-distance wheel 6, a rotating shaft 7, and a wheel frame 5. The wheel frame 5 is set on the implement frame 3, and the fixed-distance wheel 6 is mounted on the rotating shaft 7 and can rotate around the rotating shaft 7. The two ends of the rotating shaft 7 are mounted on the wheel frame 5. The fixed-distance wheel 6 is located in front of the ditching bend 4. like Figure 2 and Figure 3 As shown, the fixed-distance wheel 6 includes a wheel surface 10, marking rods 8, a roller 21, and support rods 22. A rotating shaft 7 passes through the roller 21, and both ends of the roller 21 are connected to the wheel surface 10. The marking rods 8 include multiple rods, which are evenly spaced around the outer edge of the wheel surface 10. The cross-section of the marking rods 8 is triangular, and its apex 9 extends to the outside of the wheel surface 10. The support rods 22 include multiple rods, which are connected between the roller 21 and the marking rods 8.
[0019] The working principle of this utility model of a suspended fixed-distance trenching machine for planting yellow willow in desert areas is as follows: During trenching, the hydraulic suspension system 2 of the tractor drives the implement frame 3 to descend, and the trenching cutter 4 is inserted into the sandy soil. The tractor pulls the implement frame to open the trench, leaving a curved trench 27 in the sand, which is the planting trench for planting yellow willow. At the same time, the implement frame 3 drives the fixed-distance wheel 6 to descend onto the sandy soil. With the tractor pulling, the fixed-distance wheel 6 rolls on the sandy soil, and the apex angle 9 on the marking rod 8 leaves a groove mark 28 on the sandy soil. The groove mark is an equidistant V-shaped groove, and the distance between the groove marks 28 can be adjusted according to the diameter of the fixed-distance wheel and the number of rods. This utility model can realize the simultaneous operation of trenching and marking. When planting yellow willow, the distance between two cuttings can be determined according to the groove mark, replacing the manual operation of marking the cutting points along the trench.
[0020] like Figure 5 As shown, the distance between the groove marks can be adjusted according to the diameter of the spacer wheel and the number of marker rods. Specifically, let the distance between the groove marks be L, the diameter of the spacer wheel be D, and the number of marker rods be N. If D = 50cm and N = 16, then L = π × 50 / 16 ≈ 9.8cm ≈ 10cm. The tractor travels at 2km / h, and the trenching cutter forms a long, narrow planting trench. Simultaneously, the spacer wheel rolls over the sand, forming groove marks 28. Each 1 / 16th revolution (approximately 10cm) of the spacer wheel triggers the marker rods 8 to roll over the groove marks. For example, if the required spacing between planted willows is 50cm, a spacer wheel with a diameter of 50cm and 16 marker rods is selected. After rolling, a spacing of approximately 10cm is left, and planting can be done on every 5 groove marks.
[0021] like Figure 2 As shown in the figure, as one embodiment of this utility model, the wheel frame 5 includes a support 19 and a crossbeam 20. The two ends of the crossbeam 20 are respectively connected to the support 19, and the front end of the support 19 is connected to the rotating shaft 7. The crossbeam 20 is mounted on the implement frame 3. The fixed-distance wheels 6 are connected to the implement frame via the wheel frame 5 and can rise and fall with the implement frame. This device can be added to existing ditching machines for low-cost modification.
[0022] like Figure 2As shown, the bracket 19 is inclined and extends forward of the trenching bend 4, and the outer edge of the spacer wheel 6 abuts against the front end of the trenching bend 4. Figure 1 As shown, the fixed-distance wheel 6 can abut against the front end of the grooved bevel 4, so that the groove mark can be closer to the groove of the bevel at the beginning and end.
[0023] like Figure 2 As shown, in a second embodiment of this utility model, it also includes a mounting plate 14, a connecting rod 11, and a tool holder. The front end of the implement frame 3 is connected to the mounting plate 14, and a tool holder is provided on the mounting plate 14. The tool holder includes two clamping plates 12 arranged on both sides of the trenching cutter 4. The upper part of the trenching cutter 4 is detachably connected to the clamping plates 12 by a positioning pin 13. The trenching cutter 4 is mounted on the implement frame 3 through the tool holder, and the trenching cutter 4 can be removed from the tool holder for easy replacement with different models of trenching cutters 4.
[0024] like Figure 2 As shown, the implement frame 3 includes a tripod 18, side wing rods 15, an upper connecting rod 16, and a lower connecting rod 17. The side wing rods 15, upper connecting rod 16, and lower connecting rod 17 are arranged between the tripod 18 and the mounting plate 14. The upper connecting rod 16 and lower connecting rod 17 are respectively connected to the top corner and bottom edge of the tripod 18, and the two bottom corners of the tripod 18 are respectively connected to the side wing rods 15. Currently, the tool holder 3 typically includes a tripod 18, an upper connecting rod 16, and a lower connecting rod 17; in this embodiment, side wing rods 15 are provided on both sides of the upper connecting rod 16 and the lower connecting rod 17 to further improve the stability of the tool holder 3.
[0025] like Figure 4 As shown, the tractor hydraulic suspension system 2 includes an upper tie rod 23, a lower tie rod 25, and a lifting hydraulic cylinder 24. The upper tie rod 23 is connected to the upper end of the tripod 18, and the two bottom corners of the tripod 18 are respectively connected to the lower tie rod 25. The lower tie rod 25 is connected to the lifting hydraulic cylinder 24. The tractor hydraulic suspension system 2 is currently commonly used to drive the tool holder 3 to rise and fall. It typically includes an upper tie rod 23, a lower tie rod 25, and a lifting hydraulic cylinder 24, and is used to drive the trenching cutter 4 to insert into the sand for trenching.
[0026] like Figure 2 and Figure 5 As shown, the trenching bevel 4 is positioned at the corresponding position in the middle of the long side of the marking rod 8. This ensures that the groove 27 of the bevel is centered on the groove mark 28, allowing the groove mark to be clearly marked along the planting furrow, thus improving its recognizability.
[0027] like Figure 4 As shown, the fixed-distance wheel 6 is also equipped with a counterweight 29, which is connected to the wheel surface by screws. The fixed-distance wheel surface has a detachable counterweight, which weighs 5kg and is suitable for sandy ground of different hardness.
[0028] 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, 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.
