DETAILED DESCRIPTION

[0026] Example 1

[0027] like Figures 1 to 8 As shown, first of all, the overall structure and inventive concept of the present invention are generally summarized. The first hydraulic motor 16 of the present invention only drives the crawler walking assembly 1 and has no transmission connection relationship with other components of the present invention; and the second hydraulic motor 18 of the present invention is used to drive the hose reel assembly, and the hose reel assembly drives the hose winding limit assembly to move through the various levels of sprocket structures.

[0028] More specifically, Figure 1 、 Figure 2 、 Figure 3 and Figure 8As shown, a self-propelled double-wing irrigation machine includes a horizontally arranged underframe 2, and crawler walking assemblies 1 are connected to both sides of the underframe 2. The crawler walking assembly 1 can better adapt to the desert Gobi terrain. The crawler walking assembly 1 can select the crawler walking system commonly used in the prior art (such as the crawler walking system of a scrap excavator). The crawler walking assembly 1 is composed of a driving wheel 39, a supporting wheel, a guide wheel, a suspension frame and other components. The driving wheel 39 of the crawler walking assembly 1 is transmission-connected to the first hydraulic motor 16, and a gantry 3 is connected to the underframe 2. A hose reel assembly is arranged in the gantry 3, and the hose reel assembly is transmission-connected to the second hydraulic motor 18. The first hydraulic motor 16 and the second hydraulic motor 18 are both transmission-connected to the hydraulic drive assembly. The first hydraulic motor 16 and the second hydraulic motor 18 are both installed on the underframe 2. A rubber hose 5 is wound around the hose reel assembly. The water source in the rubber hose 5 comes from a deep well in the desert. Groundwater is pumped into the rubber hose 5 by a deep well pump. The drum assembly is rotatably connected to the gantry 3, and irrigation wing pipes 6 are horizontally connected to both sides of the gantry 3. The rubber hose 5 is connected to the irrigation wing pipes 6. Several water outlet pipes 23 are evenly distributed on the irrigation wing pipes 6 along the length direction, and a water outlet hose 24 is connected to the water outlet pipe 23. A hose stabilizing assembly matching the water outlet hose 24 is provided on the irrigation wing pipe 6. The hose stabilizing assembly can effectively prevent the water outlet hose 24 from shaking during walking and failing to align with the irrigation pit position. An elastic telescopic walking assembly is installed at the bottom end of the hose stabilizing assembly. The elastic telescopic walking assembly has a vertical elastic telescopic function and can adapt well to desert terrain. A hose winding limit assembly is also provided on the vehicle underframe 2, and the hose winding limit assembly is transmission-connected to the hose reel assembly. The hose winding limit assembly is used to control the orderly winding of the rubber hose 5 along the length direction of the hose reel assembly (disorderly winding will cause the rated winding length of the rubber hose 5 on the hose reel assembly to be sharply reduced).

[0029] like Figure 3 and Figure 6 As shown, the hose reel assembly includes a hose reel 4, on which the rubber hose 5 is wound, and limit plates 36 are connected to both ends of the hose reel 4. A central tube 11 is provided in the center of the hose reel 4, and the central tube 11 is fixedly connected to the limit plates 36. The central tube 11 is rotatably connected to the gantry 3, and a connecting tube 12 is connected to the central tube 11. The end of the connecting tube 12 is connected to the rubber hose 5, and a distribution water pipe 13 is rotatably connected to one end of the central tube 11, and a water valve is installed on the distribution water pipe 13, and the distribution water pipe 13 is connected to the irrigation wing pipe 6.

[0030] like Figure 2and Figure 3 As shown, the hose winding limit assembly includes a bidirectional screw 20, both ends of the bidirectional screw 20 are rotatably connected to the vehicle chassis 2, a movable sleeve 21 is transmission-connected to the bidirectional screw 20, the bidirectional screw 20 can make the movable sleeve 21 move in both directions, a limit frame 22 is connected to the movable sleeve 21, the rubber hose 5 is located in the limit frame 22, one end of the bidirectional screw 20 is connected to the first sprocket 14, the first sprocket 14 is transmission-connected to the second sprocket through the first chain 37, the second sprocket and the third sprocket 17 are coaxially fixedly installed on the central tube 11, the third sprocket 17 is connected to the fourth chain 38 through the second chain 39. The fourth sprocket 19 is connected to the second hydraulic motor 18, and the power of the hose reel assembly is linked to the hose winding limit assembly to ensure that the rubber hose 5 is wound more orderly and compactly along the length direction of the hose reel 4, thereby increasing the total length of the rubber hose 5 and meeting the needs of long-distance irrigation; specifically, when the bidirectional screw 20 rotates, the movable sleeve 21 moves horizontally on the bidirectional screw 20, wherein the limit frame 22 and the rubber hose 5 in the limit frame 22 can limit each other, that is, the limit frame 22 can drive the rubber hose 5 to move horizontally, and the rubber hose 5 can limit the limit frame 22 from excessive rotation, thereby realizing the function of the hose winding limit assembly.

[0031] like Figure 2 As shown, in order to improve the stability of the water outlet hose 24, the hose stabilizing assembly includes two stabilizing plates 25 arranged on both sides of the water outlet pipe 23. The two stabilizing plates 25 are connected by a connecting beam 35. A through hole is opened on the connecting beam 35, and the water outlet hose 24 is inserted into the through hole.

[0032] like Figure 4 and Figure 7 As shown, in order to adapt to the desert Gobi terrain, the roller 28 can achieve vertical elastic movement. The stabilizing plate 25 is L-shaped, and a sliding square hole is vertically opened at the bottom of the stabilizing plate 25. The elastic telescopic walking component includes a vertically arranged square column 26, and a square column 26 is slidably inserted in the sliding square hole. The top and bottom ends of the square column 26 are respectively connected to a limiting plate 30 and a wheel seat 27, and the roller 28 is rotatably connected to the wheel seat 27. A compression spring 29 is mounted on the square column 26, and the compression spring 29 is located between the wheel seat 27 and the stabilizing plate 25. In order to further improve the stability of the water outlet hose 24, a threaded through hole is horizontally opened on the stabilizing plate 25, and a screw 32 is screwed in the threaded through hole. A semicircular lock buckle 31 is rotatably connected to the inner end of the screw 32, and the lock buckle 31 is used to fix the water outlet hose 24.

[0033] like Figure 5 and Figure 8As shown, the hydraulic drive assembly includes a diesel engine 33, a hydraulic pump station 34, hydraulic pipelines (not shown in the drawings), a control valve and a steering valve. The hydraulic drive assembly is a hydraulic system commonly found in crawler travel systems such as excavators. The basic principle is that the diesel engine 33 provides power to the hydraulic pump station 34, converting mechanical energy into hydraulic energy. The hydraulic pump station 34 inputs hydraulic oil into each hydraulic motor through the hydraulic pipeline, generating torque through rotation. Specifically, Figure 1 As shown, the first hydraulic motor 16 drives the driving wheel 39 to rotate, and the meshing teeth on the driving wheel 39 mesh with the inner teeth of the crawler track of the crawler walking assembly 1, thereby driving the crawler walking assembly 1 forward or backward, and the control valve is used to control the flow direction and flow of the hydraulic oil to achieve speed adjustment of the crawler walking assembly 1, and the steering valve is used to control the direction of the crawler walking assembly 1. This is a conventional technology in this field and will not be described here.

[0034] Example 2

[0035] like Figure 1 and Figure 2 As shown, in order to extend the length of the irrigation wing tube, increase the walking coverage area, and thus further improve the irrigation efficiency, Example 2 further adds an anchor cable structure on the basis of Example 1; more specifically, since the longer the irrigation wing tube 6, the more irrigation pits there are per unit walking time, and the higher the irrigation efficiency, a wing tube rack 7 is fixedly connected above the irrigation wing tube 6, and the wing tube rack 7 is fixedly connected to the gantry 3, and a vertical pole 8 is connected obliquely upward on the crawler walking assembly 1, and the vertical pole 8 is fixedly connected to the wing tube rack 7, and a first anchor cable 9 and several second anchor cables 10 are connected to the top of the vertical pole 8, the bottom end of the first anchor cable 9 is connected to the gantry 3, and the bottom end of the second anchor cable 10 is connected to the wing tube rack 7.

[0036] like Figures 1 to 8As shown, the working principle of the present invention is explained in detail. First of all, it should be noted that the circulation order of irrigation water is the desert deep water well, rubber hose 5, connecting pipe 12, central pipe 11, distribution water pipe 13, irrigation wing pipe 6, outlet pipe 23, outlet hose 24, and Haloxylon ammodendron pit; when in use, the hydraulic drive assembly drives the first hydraulic motor 16 and the second hydraulic motor 18 to rotate, the first hydraulic motor 16 drives the crawler walking assembly 1 to move slowly, and the second hydraulic motor 18 drives the hose drum assembly to rotate, and adjusts the control valve to make the walking speed of the crawler walking assembly 1 adapt to the rotation speed of the hose drum assembly (that is, the release or winding speed of the rubber hose 5 is adapted to the walking speed of the crawler walking assembly 1). When it reaches a row of irrigation pits, it stops walking, opens the water valve on the distribution water pipe 13, and allows the outlet hose 24 to water the pit, and then continues walking to irrigate the next row of pits; it is worth noting that the diameter of the Haloxylon ammodendron pit is generally above 50 cm, and the outlet hose 24 is irrigated into the pit. The diameter of the hose 24 is generally about 5 cm, which has a large margin, thereby compensating for the walking error of the crawler walking assembly 1 and the error in the pit opening position, ensuring accurate irrigation of the water outlet hose 24; when the hose reel assembly rotates, the central tube 11 rotates together with the second sprocket, and the second sprocket drives the first sprocket 14 to rotate through the first chain 37, thereby driving the bidirectional screw 20 to rotate, and the bidirectional screw 20 drives the movable sleeve 21 and the limit frame 22 to move horizontally, and the rubber hose 5 moves in an orderly manner with the limit frame 22, thereby ensuring that the rubber hose 5 is wound or released in an orderly manner along the length direction of the hose reel 4, greatly increasing the total length of the rubber hose 5 wound on the hose reel 4, and realizing ultra-long distance irrigation; it is worth noting that due to the limitation of the drawing and for clearer expression, only 4 water outlet pipes 23 are matched on the irrigation wing pipe 6 in Example 2 of the present invention, but in actual application, in order to improve irrigation efficiency, the number of water outlet pipes 23 on the single-side irrigation wing pipe 6 can be increased to 10 or more.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
