[0023] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Referring to Figures 1 - 2 , the present utility model provides a pit-digging device for fruit tree planting, including:

[0025] A lifting arm frame, which is installed on an agricultural machine;

[0026] A fixed frame 1, which is installed at the end of the lifting arm frame. A separable mounting frame is fixedly connected to the fixed frame 1, and the separable mounting frame is arranged in a ring structure;

[0027] Digging mechanism, the digging mechanism includes three groups of digging components. The three groups of digging components are arranged at equal circumferential intervals on an openable and closable mounting frame. Each digging component includes a fixed arm 2 fixedly connected to the openable and closable mounting frame. The cross-sectional shape of the fixed arm 2 is in the shape of a "C". An angle is provided between the axis of the fixed arm 2 and the openable and closable mounting frame. A sliding sleeve 3 is slidably sleeved on the fixed arm 2. The fixed arm 2 is rotatably connected to a first hydraulic telescopic rod 4. One end of the first hydraulic telescopic rod 4 is rotatably connected to the inner wall of the sliding sleeve 3. A digging plate 5 is fixedly connected to the bottom of the side of the sliding sleeve 3;

[0028] Among them, the digging plates 5 of the three groups of digging components are arranged in an inverted conical structure.

[0029] When the present utility model is in use, the device is connected to the agricultural machinery through a lifting boom. The lifting boom controls the overall digging mechanism to lift and lower. When reaching the digging position, the lifting boom controls the fixed frame 1 and the digging mechanism on the fixed frame 1 to lower. The first hydraulic telescopic rod 4 of one group of digging components works, pushing the sliding sleeve 3 to slide along the fixed arm 2, so that the digging plate 5 is inserted into the soil. Then the other two groups of digging components work in sequence for digging. The lifting boom rises to complete the digging work. The sapling is placed in the tree pit, and the openable and closable mounting frame is opened, so that the soil between the three groups of digging components is backfilled into the tree pit to complete the planting.

[0030] The present utility model excavates the tree pit through the cooperation of three groups of digging components. After excavation, the excavated soil can be directly backfilled into the tree pit, reducing the intensity of manual operation.

[0031] In a further optimized scheme, two groups of lifting booms are symmetrically designed on the agricultural machinery. The lifting boom includes a fixed rod 6 rotatably connected to the agricultural machinery. One end of the fixed rod 6 is rotatably connected to a connecting arm 7.

The connecting arm 7, the second hydraulic telescopic rod 8, and the agricultural machinery are arranged in a triangular structure. A third hydraulic telescopic rod 9 is installed at the bottom of the agricultural machinery. The third hydraulic telescopic rod 9 is hinged to the end of the fixed frame 1 away from the connecting arm 7, and an angle is provided between the third hydraulic telescopic rod 9 and the fixed frame 1.

[0032] The setting of the lifting boom can control the lifting and lowering of the overall device. The second hydraulic telescopic rod 8 cooperates with the fixed rod 6 to control the lifting and lowering of the connecting arm 7, and the connecting arm 7 drives the fixed frame 1 to lift and lower. Since the fixed frame 1 will generate an angular deflection during the rising process of the connecting arm 7, in this embodiment, the third hydraulic telescopic rod 9 is provided. The setting of the third hydraulic telescopic rod 9 forms a linkage with the second hydraulic telescopic rod 8 to ensure that the fixed frame 1 is in a stable and horizontal state and prevent the device from tipping over.

An opening and closing assembly is installed on the first mounting plate 10, and the opening and closing assembly is rotatably connected to the second mounting plate 11.

[0034] For a further optimized solution, the opening and closing assembly includes a fourth hydraulic telescopic rod 12 rotatably connected to the outer wall of the end of the first mounting plate 10. One end of the fourth hydraulic telescopic rod 12 is rotatably connected to the end of the second mounting ring. The setting of the fourth hydraulic telescopic rod 12 can open the first mounting plate 10 and the second mounting plate 11, so as to facilitate the release of the soil between the three excavation plates 5 for filling the tree pit.

The clamping block 13 is adapted to the clamping groove. The setting of the clamping block 13 and the clamping groove can make the first mounting plate 10 and the second mounting plate 11 form a complete ring structure to ensure the bearing capacity of the overall openable mounting bracket.

[0036] For a further optimized solution, scale lines are provided on the fixed arm 2. The scale lines corresponding to the sliding sleeve 3 can calculate a certain distance of the sliding sleeve 3, so as to determine the depth of the dug hole.
