[0039] Refer to Figures 1 to 8 As shown in the figure, a tree planting and pit digging device for landscaping project construction is characterized by comprising: a bearing frame 1, a pit digging mechanism 2, a control mechanism 8, two universal wheels 5, and legs 6;

[0040] The universal wheels 5 and the legs 6 are both installed at the bottom of the bearing frame 1 and are used to move and support the bearing frame 1;

[0041] The control mechanism 8 is installed on the bearing frame 1 and is used to control and adjust the pit digging mechanism 2;

[0042] The pit digging mechanism 2 is slidably arranged on the bearing frame 1 and is connected to the control mechanism 8. The pit digging mechanism 2 is used for breaking the soil and controlling the falling of fertilizer after the soil breaking is completed;

[0043] Specifically, the pit digging mechanism 2 includes: a first motor 7, a feeding bin 21, a spiral earth digging roller 22, a discharge adjustment assembly 24, and a bearing plate 27;

[0044] The bearing plate 27 is slidably arranged on the bearing frame 1, and the first motor 7 is arranged on the bearing plate 27; the output end of the first motor 7 is coaxially fixed to one end of the discharge adjustment assembly 24, and the other end of the discharge adjustment assembly 24 is coaxially fixed to the spiral earth digging roller 22;

[0045] One end of the feeding bin 21 is fixed on the bearing plate 27, and the other end is rotatably arranged on the spiral earth digging roller 22.

[0046] It should be noted that the equipment is moved to the working area through the universal wheels 5. The control mechanism 8 is adjusted to select a reasonable digging depth. After the adjustment is set, the first motor 7 is started and rotated forward, so as to drive the spiral earth-digging roller 22 to rotate forward. At the same time, under the action of the control mechanism 8, the spiral earth-digging roller 22 drops, so as to carry out the soil digging operation. When the spiral earth-digging roller 22 is digging the pit, the blanking adjustment component 24 can effectively prevent the fertilizer from falling. After reaching the preset digging depth, the first motor 7 rotates reversely, and at the same time the control mechanism 8 makes the spiral earth-digging roller 22 rise to return to the initial state. During the reverse rotation of the spiral earth-digging roller 22, the blanking adjustment component 24 makes the fertilizer fall, and under the action of centrifugal force, it is evenly scattered into the soil pit through the spiral earth-digging roller 22, that is, the fertilizer is sown while digging the soil, improving the tree planting efficiency.

[0047] The blanking adjustment component 24 includes:

[0048] The adjusting inclined table 241 is coaxially fixed at one end with the first motor 7 and coaxially fixed at the other end with the spiral earth-digging roller 22; a plurality of material guiding grooves are formed in the adjusting inclined table 241;

[0049] The blanking control table 242 is installed in the material guiding groove; when the first motor 7 rotates forward, that is, when digging the soil, it is used to prevent the fertilizer from spilling; when the first motor 7 rotates reversely, that is, when the digging is completed, it is used to control the spilling of the fertilizer.

[0050] The blanking control table 242 includes:

[0051] The guiding table 2421 is fixed at one end on the material guiding groove, and a deflector is fixed at the other end at an angle of 15°; a blanking table 2422 is rotatably arranged on the guiding table 2421;

[0052] The guiding table 2421 and the blanking table 2422 form an adjusting bin; when the first motor 7 rotates forward, the deflector prevents the fertilizer from entering the adjusting bin; when the first motor rotates reversely, the deflector makes the fertilizer enter the adjusting bin.

[0053] A torsion spring is arranged at the rotating connection shaft of the guiding table 2421 and the blanking table 2422; the material guiding bin 21 includes: a bin body 211, a blanking port 212, and a sliding table 213; one end of the bin body 211 is fixed on the bearing plate 27, and the other end is fixed with the sliding table 213; blanking ports 212 are symmetrically formed in the bin body 211; the blanking port 212 is communicated with the feeding port 3; the feeding port 3 is fixed on the bearing plate 27; a guide rail 25 is formed at one end of the spiral earth-digging roller 22 close to the bearing plate 27; the sliding table 213 is slidably arranged in the guide rail 25; the middle shaft of the spiral earth-digging roller 22 is of a hollow structure and is communicated with the material guiding bin 21, and a blanking hole 26 is formed at the end of the middle shaft.

[0054] It should be explained that when the first motor 7 rotates forward, the guide table 2421 rotates forward synchronously. Due to the inclined setting of the lever, when the baffle plate contacts the fertilizer, it can prevent the fertilizer from entering the adjustment bin, so that the original fertilizer in the storage bin cannot deflect the blanking table 2422, that is, the fertilizer cannot fall.

[0055] When the first motor rotates reversely, the lever will squeeze a part of the fertilizer in contact with it into the adjustment bin during the contact process. Since the fertilizer is pressed into the adjustment bin, the blanking table 2422 can overcome the torque of the torsion spring, that is, deflect the blanking table 2422, so that the fertilizer in the adjustment bin can pass through the central axis under the action of centrifugal force and be evenly sprinkled into the dug soil pit through the blanking holes 26, that is, complete the fertilizer spreading for tree planting.

[0056] The present utility model further includes: The control mechanism 8 includes:

[0057] A lead screw 82 is rotatably arranged on the carrier 1 and is threadedly connected with a nut 83; the nut 83 is connected with the carrier plate 27;

[0058] A second motor is fixed on the carrier 1, and its output end is coaxially fixed with the lead screw 82;

[0059] A control module 84 is fixed on the carrier 1 for adjusting and controlling the second motor and the soil digging mechanism 2.

[0060] It should be noted that the control module 84 can reasonably adjust the digging depth of the soil by the digging mechanism 2 according to different tree species. After setting the digging depth, the control module 84 controls the first motor 7 and the second motor to start simultaneously, so that the digging mechanism 2 slowly descends to dig the soil. After completing the digging, the digging mechanism 2 is restored to the initial state.

[0061] Among them, the second motor is preferably a stepping motor.

[0062] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
