[0035] Please refer to Figure 1 , Figure 3 and Figure 4 , the limit mechanism 5 includes a sliding frame 51, a lifting frame 52, a connecting frame 53, a first fixed sleeve 54 and a first spring 55. The sliding frame 51 is slidably connected to the limit frame 4. Connecting frames 53 are fixedly connected to both the front and rear sides of the sliding frame 51. The end of one of the connecting frames 53 is fixed to the outer wall of the first fixed sleeve 54, and the end of the other connecting frame 53 is also fixed to the outer wall of the first fixed sleeve 54. The lifting frame 52 is slidably connected in the first fixed sleeve 54. A first spring 55 is arranged between the bottom of the lifting frame 52 and the bottom wall of the adjacent first fixed sleeve 54. The first spring 55 can drive the lifting frame 52 to move and reset.

[0036] Please refer to Figure 1 , Figure 5 and Figure 6 , the moving mechanism 6 includes a double-shaft motor 61, a wire winding wheel 62, a first rope 63, a second rope 64, a first wire guide frame 65 and a second wire guide frame 66. The double-shaft motor 61 is fixed in the sliding plate frame 3. The two output shafts of the double-shaft motor 61 penetrate through the sliding plate frame 3. Wire winding wheels 62 are arranged on the two output shafts of the double-shaft motor 61. Second ropes 64 are connected to the wire winding wheels 62. The second ropes 64 are connected to the rear connecting frame 53. First ropes 63 are wound around the wire winding wheels 62. The first ropes 63 are connected to the front connecting frame 53. The rear part of the limit frame 4 is fixedly connected with a first wire guide frame 65. The second rope 64 penetrates through the first wire guide frame 65. The front part of the limit frame 4 is fixedly connected with a second wire guide frame 66. The first rope 63 penetrates through the second wire guide frame 66.

[0037] Please refer to Figure 1 , Figure 9 and Figure 10, the pressing mechanism 8 includes a second fixed sleeve 81, a fourth spring 82 and a slope plate 83. Second fixed sleeves 81 are fixed to the left and right sides of the bottom of the limit frame 4. A slope plate 83 is slidably connected inside the second fixed sleeve 81. A fourth spring 82 is provided between the top of the slope plate 83 and the inner top wall of the second fixed sleeve 81. The slope plate 83 is arranged corresponding to the lifting frame 52, and the fourth spring 82 can drive the slope plate 83 to move back to its original position.

[0038] Please refer to Figure 1 , Figure 7 and Figure 8 , the clamping mechanism 7 includes a clamping block 71, a second spring 72, a clamping plate 73 and a third spring 74. Clamping blocks 71 are slidably connected to the front and rear sides of the lifting frame 52. A second spring 72 is provided between the mutually remote sides of the clamping blocks 71 and the lifting frame 52. A clamping plate 73 is slidably connected inside the lifting frame 52. Third springs 74 are arranged between the front and rear sides of the bottom of the clamping plate 73 and the lifting frame 52. The third spring 74 can drive the clamping plate 73 to move back to its original position. Initially, the clamping plate 73 is in a state of clamping the clamping blocks 71, and the second spring 72 is in a compressed state; when the rod contacts the clamping plate 73, the clamping plate 73 will move downward, the third spring 74 is compressed, the clamping plate 73 moves downward and separates from the clamping blocks 71, and under the action of the second spring 72, it drives the clamping blocks 71 to move back to the mutually close side, and the clamping blocks 71 can clamp and limit the rod. In this way, during the process of unloading the rod, the stability of the rod can be improved. When it is necessary to remove the rod from the lifting frame 52, the clamping blocks 71 can be pulled to the mutually remote side, the second spring 72 is compressed, and then the rod is taken out. Subsequently, under the action of the third spring 74, it drives the clamping plate 73 to move upward and reset to clamp the clamping blocks 71 again. Repeating the above operations can conveniently clamp the rod.

[0039] Please refer to Figure 1 , Figure 11 and Figure 12 , the unlocking mechanism 9 includes a lifting plate 91. Limit slots 93 are opened on the front and rear sides of the lifting frame 52. The clamping plate 73 is slidably connected with the limit slots 93. A lifting plate 91 is slidably connected to the lifting frame 52. The unlocking mechanism 9 further includes a pulling rod 92. One end of the pulling rod 92 is fixed to the lifting plate 91. When the lifting plate 91 moves upward, it can push the clamping blocks 71 outward to unlock. The pulling rod 92 can drive the lifting plate 91 to move upward. If it is necessary to move the clamping blocks 71 to the mutually remote side, the pulling rod 92 can be held and moved upward to drive the lifting plate 91 to move upward. The lifting plate 91 can contact the clamping blocks 71, so that the clamping blocks 71 move to the mutually remote side. In this way, unlocking can be facilitated, so that the clamping blocks 71 release the rod, and then the pulling rod 92 can be used to drive the lifting plate 91 to move downward and reset.

[0040] Please refer to Figure 1and Figure 13 The rolling mechanism 10 includes a roller 101 and a limiting plate 102. Limiting plates 102 are fixed on both sides of the support frame 2. The roller 101 is evenly and rotatably connected to the limiting plate 102. The end of the roller 101 is rotatably arranged on the support frame 2. The roller 101 can facilitate the movement of the sliding plate frame 3. According to the position of the pole, the sliding plate frame 3 and the components thereon can be adjusted back and forth. By moving the sliding plate frame 3 back and forth, under the action of the roller 101, the movement of the sliding plate frame 3 can be facilitated, so that the position of the lifting frame 52 is adjusted properly.

[0041] Specifically, the working principle of the rod loading and unloading device of the horizontal directional drill: When in use, when it is necessary to unload the rod on the horizontal directional drill, this device is used for operation. First, the fixing frame 1 is fixed on the front side of the horizontal directional drill through bolts. At this time, the rod is in the middle position at the top of the limiting frame 4. If it is necessary to unload the rod, first control the double-shaft motor 61 to work. The output shaft of the double-shaft motor 61 rotates to drive the wire winding wheel 62 to wind up the second rope 64, and loosen the first rope 63. The second rope 64 pulls the connecting frame 53 to move backward. The connecting frame 53 drives the sliding frame 51, the first fixed sleeve 54 and the lifting frame 52 to move backward. When the lifting frame 52 moves backward and contacts the slope plate 83, the slope plate 83 can press down the lifting frame 52, and the first spring 55 is compressed. Moreover, when the lifting frame 52 continues to move backward, since the lifting frame 52 is in the lowest position, the lifting frame 52 will not contact the rod when moving backward. Subsequently, control the output shaft of the double-shaft motor 61 to reverse, drive the wire winding wheel 62 to reverse, so that the wire winding wheel 62 loosens the second rope 64 and winds up the first rope 63 at the same time. At this time, the first rope 63 will pull the front connecting frame 53 to move forward, thereby making the sliding frame 51, the first fixed sleeve 54 and the lifting frame 52 move forward. When the lifting frame 52 separates from the slope plate 83, under the action of the first spring 55, it drives the lifting frame 52 to move upward and reset, and the lifting frame 52 will lift the rod. Then the lifting frame 52 will continue to move forward to drive the rod to move forward, so that the rod can be automatically conveyed forward for discharging.

[0042] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application.

[0043] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
