DETAILED DESCRIPTION

[0034] The embodiment is described in detail in combination with the drawings when in use.

[0035] The width of the trolley is selected according to the density of the bamboo forest during use, so that the trolley can normally travel in the bamboo forest, and the selected bamboo forest land is a flat land or a slope with a certain slope, the slope of the slope is within the climbing performance range of the walking trolley 1, and the storage bin in the walking trolley 1 is filled with fertilizer required for fertilization on the current ground before use, and then the travel route and operation range of the walking trolley 1 are planned.

[0036] After the preparation work is completed, the walking trolley 1 travels in the planned range, the soil turning device is stored in the walking trolley 1 in the initial state, the walking trolley 1 travels intermittently, and the walking trolley 1 switches between walking and stopping during walking. During the stopping period of the walking trolley 1, a soil turning and fertilizing action is completed by the soil turning device. The soil turning is performed when the walking trolley 1 is stopped. In the initial state, the supporting shell 2 is a hollow structure with an open lower end, and two transversely arranged and parallel driving threaded rods 3 are arranged on the inner side of the supporting shell 2. Two driving threaded rods 3 are respectively threadedly connected with a moving rod 4, the moving rod 4 is transversely arranged, and the upper end of the moving rod 4 is slidably connected with the supporting shell 2. At the same time, the moving rod 4 moves transversely when the driving threaded rod 3 rotates. The moving rod 4 is rotatably connected with a connecting rod 5 at both ends, the two connecting rods 5 are respectively downwardly extended and arranged in parallel between the two connecting rods 5, and the two connecting rods 5 are respectively downwardly extended at the extended ends. Each connecting rod 5 is rotatably connected between the downwardly extended connecting rod 5 and the lower pressing driving rod 6. The downwardly extended connecting rod 5 is rotatably connected between the middle part of the pressing driving rod 6 and the end of the pressing driving rod 6 close to the middle part of the supporting shell 2. The middle part of the pressing driving rod 6 and the end of the supporting shell 2 are connected by an auxiliary rod 7. The auxiliary rod 7 and the connecting rod 5 are the same length, so that the middle part of the pressing driving rod 6 is rotatably connected with the extended end of one connecting rod 5 and one auxiliary rod 7. At the same time, the rotary connection parts are coaxially arranged, and the pressing driving rod 6 is transversely arranged.

[0037] A plurality of vertical through grooves are formed on the pressing driving rod 6, and each vertical through groove is fixedly connected with a longitudinally arranged rotating hole, and each rotating hole is rotatably connected with a soil turning claw 8, and the upper end of each soil turning claw 8 penetrates through the corresponding through groove and extends upward, and the upper end of each soil turning claw 8 is synchronously driven by the transversely sliding transverse driving rod 9 connected to the upper end of the pressing driving rod 6, and the soil turning claw 8 comprises a vertically arranged square connecting portion 14 and an arc-shaped soil turning portion 15 located at the lower end of the square connecting portion 14, and the square connecting portion 14 is provided with a longitudinally arranged rotating portion 16, and the soil turning portion 15 is a hollow structure with an opening downward, and one end of the rotating portion 16 is provided with a groove in communication with the inner hollow structure of the soil turning portion 15, and the lower end of each soil turning claw 8 extends outwardly, and the transverse driving rod 9 and the pressing driving rod 6 are driven by the transversely arranged electric telescopic rod 11, and the transverse relative movement of the electric telescopic rod 11 and the pressing driving rod 6 drives the upper end of each soil turning claw 8, so that when the upper end of the soil turning claw 8 moves, the upper end of the soil turning claw 8 is rotatably and slidingly connected between the straight groove 10 and the rotating shaft of the transverse driving rod 9 to be driven, so that the angle of the lower end of the soil turning claw 8 changes, and since the lower end of the soil turning claw 8 is arc-shaped and extends downwardly and outwardly.

[0038] Before the downward movement of the pressing driving rod 6, the transverse driving rod 9 is moved outwardly, so that the downwardly extending end of each soil turning claw 8 approaches the downwardly extending end, and after the soil turning claw 8 contacts the ground, it is continuously pressed downwardly, and since the pressing driving rod 6 moves downwardly during the pressing process, it is more easily inserted into the ground, and after continuing to move downwardly and being inserted into the ground to a certain depth, the inward movement of the transverse driving rod 9 is controlled by the contraction of the electric telescopic rod 11, so that the lower end of each soil turning claw 8 is synchronously raised when the transverse driving rod 9 moves, so that the soil is turned during the raising process.

[0039] In order to turn the soil in the bamboo forest land with a certain slope, the movement rod 4 is a two-segment structure, and the two-segment movement rod 4 is connected by the reset spring 13, so that the reset rod can be stretched and contracted by a certain amount, and the change in the length of the reset rod changes the distance between one end of the two connecting rods 5, which changes the inclination angle of the lower pressing driving rod 6, so that it can adapt to various terrains with a certain slope, and can be used in various scenes during use, and since the middle part of the pressing driving rod 6 is the main downward pressing force point, the inclination of the pressing driving rod 6 does not affect the pressing force of the downward extension of the soil turning claw 8.

[0040] The filler mechanism is connected to the outside of each turning tine 8 for fertilizing the ground during turning. The supply pipe 17 is rotatably connected to the notch on each rotating part 16. One end of each supply pipe 17 is rotatably connected to the notch, and the other end extends upward. The upward extending end of each supply pipe 17 is connected to the obliquely arranged distribution pipe 18. The walking trolley 1 is provided with a storage bin. The obliquely upward extending end of the distribution pipe 18 is connected to the lower end of the storage bin in the walking trolley 1 through a hose. The material in the storage bin is guided into the distribution pipe 18 on each turning tine 8 through the hose, and then into the hollow structure in each turning tine 8.

[0041] The supply pipe 17 is longitudinally arranged, and the lower end of the supply pipe 17 is provided with a discharge port 19 corresponding to the position of the hollow structure in the turning part 15. The discharge port 19 and the hollow structure in the turning part 15 are switched in communication state by the different rotation angles of the turning tine 8. During the process of the lower end of each turning tine 8 extending downward and being inserted into the ground, the discharge port 19 and the turning tine 8 are not in communication. When the turning tine 8 is rotated and the ground is lifted, the discharge port 19 is in communication with the hollow structure in the turning tine 8, so that the material falls downward from the opening at the lower end of the turning tine 8 into the excavated ground. Then, after the fertilizing and plowing are completed, the turning tine 8 is restored to the state of extending downward, so that the discharge port 19 is closed. In this way, the fertilizer is not wasted, and the quantitative and uniform supply of the fertilizer is maintained. Thus, the process of turning and fertilizing is completed. Then, the reverse movement is performed to make the soil turning device be stored, and the walking trolley 1 is controlled to continue moving forward and perform the next cycle of turning and fertilizing. Since the soil turning device extends outward and has a flat structure, the soil turning and fertilizing can be performed in the gap between the bamboo forests within the limited walking range. After the fertilizing is completed, the soil turning device is stored, so that no obstruction is caused during the walking. The range of turning and fertilizing is much larger than the width of the walking trolley 1. At the same time, the range of each work is wider, and the fertilizer is uniformly distributed in the working area, so that the automatic fertilizing and plowing of the bamboo forests are realized.

[0042] Obviously, the above embodiments are only examples for clearly illustrating the application, and are not intended to limit the application. Based on the above description, other different forms of changes or modifications can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or modifications derived therefrom are still within the protection scope of the claims of the present patent application.
