The lifting device comprises a plurality of mutually hinged frames and telescopic devices 110, wherein the frames are mutually connected to form a connecting rod mechanism. The distribution frame 70 is fixedly connected to the frame, and one end of the distribution frame 70 is arranged on the side of the travel direction of the fruit tree fertilization device, and extends a certain distance from the frame, so that the end of the distribution frame 70 can extend below the crown of the fruit tree. The length of the end of the distribution frame 70 extending from the frame can be determined according to the crown diameter of the fruit tree or the distance between the area to be fertilized and the trunk of the fruit tree. The larger the crown diameter or the closer the distance between the area to be fertilized and the trunk of the fruit tree, the longer the distance of the end of the distribution frame 70 extending from the frame. The distributor 60 is fixedly arranged at one end of the distribution frame 70 extending from the side of the frame, so that the distribution frame 70 can effectively fertilize the area below the crown of the fruit tree. The lifting device is configured to be actuated by the push frame used for the extension and retraction of the extension device 110 to push the distributor 60 up and down, so that the distributor 60 is inserted into the soil during fertilization and pulled out from the soil after fertilization.

[0031] Preferably, an adjustment slot is provided at the upper end of the driving connecting frame 80. The setting of the adjustment slot can realize the adjustment of the distribution frame 70 in the height direction, and then adjust the fertilization height of the distributor 60, so that the fruit tree fertilization device can adapt to various terrains.

[0032] Preferably, the telescopic device 110 is one of a pneumatic cylinder, a hydraulic cylinder or an electric push rod.

[0033] The distributor 60 includes a fixed block 62, a ditching member 65 and a distribution pipe 66. The ditching member 65 is arranged vertically and fixedly connected to the fixed block 62. A feed pipe 63 connected to the inside of the distribution pipe 66 is fixedly arranged above the distribution pipe 66. The feed pipe 63 is used to connect to a storage box or storage barrel for storing fertilizer so that the fertilizer enters the distribution pipe 66. The distribution pipe 66 is fixedly connected to the fixed block 62 or the ditching member 65; the cross section of the ditching member 65 is "V" shaped, and the opening of the ditching member 65 is arranged at the rear of its travel path; the distribution pipe 66 is arranged on the opening side of the ditching member 65. The ditching member 65 can loosen the soil in front of the distribution pipe 66, so that the waste in the distribution pipe 66 can be discharged into the soil.

[0034] Preferably, the lower end surface of the distribution pipe 66 is at a higher horizontal position than the lower end surface of the trenching member 65, so that the lower end surface of the distribution pipe 66 can effectively discharge solid or liquid fertilizers and is not easily blocked by soil.

[0035] Preferably, the distributor 60 further includes a front reinforcing rib plate 64 fixedly connected to the groove opening member 65 and a rear reinforcing rib plate 67 fixedly connected to the distribution pipe 66 .

[0036] As another embodiment of the utility model, the fruit tree fertilization device also includes an adjustment mechanism for adjusting the position of the distribution tube 66 in the horizontal direction. The adjustment mechanism includes a slider 61 and an adjustment member 120 having a slide groove 130. The cross section of the slide groove 130 is a non-circular structure, so that the distribution tube 66 will not move in the travel direction of the fruit tree fertilization device. The adjustment member 120 is fixedly connected to the distribution frame 70. The slide groove 130 is arranged perpendicular to the plane where the travel path of the ditching member 65 is located.

[0037] Specifically, the position adjustment device 50 includes a first bearing seat 51, a lead screw 52 and a second bearing seat 53. The first bearing seat 51 and the second bearing seat 53 are arranged on the same straight line parallel to the slide groove 130 along the length direction of the material distribution frame 70. The first bearing seat 51 and the second bearing seat 53 are both fixedly connected to the material distribution frame 70. One end of the lead screw 52 is rotatably connected to the first bearing seat 51, and the other end of the lead screw 52 is rotatably connected to the second bearing seat 53. The distributor 60 also includes a transmission block 68 fixedly connected to the fixed block 62, and a threaded hole 69 is provided on the transmission block 68, and the lead screw 52 is threadedly connected to the transmission block 68.

[0038] Preferably, an adjusting head 54 for adjusting the rotation of the lead screw 52 is also provided at the outer end of the lead screw 52. The adjusting head 54 is a rectangular parallelepiped structure, which is convenient for twisting the lead screw 52 using tools such as a wrench.

[0039] As another embodiment of the utility model, the fruit tree fertilizing device further includes a fixed beam frame 10 fixedly connected to the traveling device 140. A vertically arranged plug-in slot is fixedly arranged on the fixed beam frame 10. The frame body further includes a plug-in frame 30 arranged vertically and fixedly connected to the disassembly beam frame 20. The plug-in frame 30 is inserted into the plug-in slot, so that the fruit tree fertilizing device can be detachably fixed to the traveling device 140.

[0040] like Figure 4 As shown, when in use, the fixed beam frame 10 is fixedly connected to the running device 140. The running device 140 can be a powered running device such as a tractor. The plug-in frame 30 is inserted into the plug-in slot fixedly connected to the fixed beam frame 10. Before entering the fertilization area, the telescopic device 110 is extended to lift the distribution frame 70, so that the lower end surfaces of the ditching member 65 and the distribution pipe 66 are higher than the soil surface, which facilitates the movement of the running device 140 equipped with the fruit tree fertilization device. After the running device 140 equipped with the fruit tree fertilization device moves to the walking area on the side of the fruit tree, since the distribution frame 70 extends a certain distance from the frame body, the distributor 60 can enter the position below the crown of the fruit tree. The telescopic device 110 is shortened to lower the distribution frame 70, so that the lower end surfaces of the ditching member 65 and the distribution pipe 66 are inserted into the soil, and the storage box or storage barrel storing fertilizer is opened, so that the fertilizer can enter the distribution pipe 66 from the feed pipe 63. At this time, the walking device 140 moves forward, driving the furrowing member 65 to furrow along the moving direction, and the fertilizer in the distribution pipe 66 continuously enters the loose soil behind the furrowing member 65, thereby realizing fertilization of the fruit trees.

[0041] In addition, for fruit trees with larger crowns, the adjusting head 54 can be twisted with a wrench or other tool to rotate the lead screw 52, ​​thereby driving the distributor 60 to move and adjust the distance between the distributor 60 and the trunk to adjust the fertilization position, making it easier to fertilize under fruit trees with different crown sizes.
