Description

Technical Field

[0001] The utility model belongs to the technical field of garden construction, in particular to a pit digging device for garden cultivation. Background Art

[0002] A garden is a place dedicated to cultivating green plants, natural environment and for people to enjoy and appreciate. It requires artificial transformation of the terrain and the planting of flowers, trees and buildings. In the process of landscaping, seedlings or transplanted trees need to be planted, and at this time, pits need to be dug. Due to the huge number, the pit mouths and depths of manual pits are of different sizes, and the labor intensity is high, which is not only time-consuming and labor-intensive, but also inefficient.

[0003] The existing pit digging device lacks stability due to the vibration generated during pit digging, and the pit digging position is easily offset. In addition, when digging a pit on an uneven or sloping ground, the pit digging device will tilt, causing the direction of the drill bit to not be vertically downward, so that the dug pit is tilted relative to the horizontal plane. The tilted pit not only tilts the seedlings after planting, affecting the appearance, but also is not conducive to the growth of the seedlings. Utility Model Content

[0004] In view of this, the utility model aims to provide a pit digging device for gardening cultivation, so as to solve the problems of low pit digging efficiency and digging inclined pits when encountering a sloping ground.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] The support assembly includes a second shell, two first cylinders, and a support plate. One side of the second shell is fixedly connected to the base and one side of the first shell. The lower end of the second shell is an open end. The two first cylinders are arranged on the top of the second shell. The support plate is slidably arranged inside the second shell through the two first cylinders.

[0008] Furthermore, the fixed ends of the two first cylinders are arranged on the top of the second housing, and the output ends of the two first cylinders are connected to the top of the support plate;

[0009] A first slide groove is provided on the lower side wall of the second shell, and first sliding blocks corresponding to the first slide groove are provided on the top of both sides of the support plate, and a plurality of evenly distributed insertion rods are provided at the bottom of the support plate; the support plate can be raised and lowered inside the second shell by the first cylinder. After pushing the device to a suitable position, the support plate is lowered before digging a hole, and the insertion rods are inserted into the ground to fix the device to prevent displacement caused by vibration during digging. When the digging position is on a slope, the support plate continues to be lowered, and the bottom of the support plate abuts against the ground, thereby lifting the rear of the device until the device is horizontal.

[0010] A handle is provided on a side of the top of the second shell away from the first shell.

[0011] Furthermore, the pit digging assembly includes two lifting assemblies, a cross bar, and a rotary digging assembly. The cross bar is horizontally arranged between the two lifting assemblies, and the rotary digging assembly is arranged on the cross bar.

[0012] Furthermore, the lifting assembly includes a column, a ball screw, and a first motor. The bottom of the column is arranged on the bottom wall of the first shell. A groove is provided on the side where the two columns are close to each other. The ball screw is arranged in the groove. The mounting end of the first motor is arranged on the top of the column. The output shaft of the first motor extends into the groove and is connected to one end of the ball screw. The other end of the ball screw is rotatably connected to the bottom of the groove.

[0013] Furthermore, two ends of the crossbar are fixedly connected to nuts of two ball screws.

[0014] Furthermore, the rotary drilling assembly includes a second motor, a rotating shaft, and a spiral blade. The mounting end of the second motor is arranged in the middle part above the crossbar. The output shaft of the second motor passes through the crossbar and is fixedly connected to one end of the rotating shaft. The spiral blade is arranged on the side wall of the rotating shaft. Starting the first motor can make the crossbar rise and fall, thereby making the rotary drilling assembly rise and fall. Starting the second motor can make the rotating shaft rotate, thereby making the spiral blade rotate. The pit is dug under the combined action of the rotation and descent of the spiral blade.

[0015] Furthermore, a first through hole is provided at the bottom of the first shell, and a second through hole corresponding to the first through hole is provided on the base.

[0020] The upper and lower ends of the third shell are both open ends, and the side walls of the third shell are provided with second slide grooves. The fixed end of the second cylinder is arranged at one end of the third shell away from the fourth through hole, and the output end of the second cylinder is connected to the blocking block, and the side walls of the blocking block are provided with second sliders corresponding to the second slide grooves. When the pit is dug and fertilizer is needed, the output end of the second cylinder is retracted, and the blocking block slides along the second slide groove to the side away from the fourth through hole to expose the fourth through hole, so that the fertilizer in the storage box falls into the dug pit along the third through hole and the fourth through hole. After the fertilizer application amount is reached, the second cylinder is controlled to extend the output end so that the blocking block abuts against the side wall of the third shell, so that the blocking block blocks the fourth through hole and stops the fertilizer from flowing out; the function of the tilting block is to prevent the fertilizer in the storage box from flowing out in the dead corner.

[0021] Furthermore, a splash shield and four rollers are provided below the base. The splash shield is conical and arranged outside the through hole and the spiral blade. The four rollers are arranged below the base, and the four rollers correspond to the four corners of the bottom of the first shell.
