Description

Technical Field

[0001] The utility model relates to the technical field of gardening equipment, in particular to a pit digging device for greening and planting. Background Art

[0002] Green plants are short for green ornamental foliage plants, most of which are grown in tropical rainforests and subtropical areas and are generally shade-loving plants. Because of their strong shade tolerance, they can be grown and maintained indoors as indoor ornamental plants. During the cultivation of green plants, it is necessary to dig a suitable size of soil pit on the ground. However, the existing pit digging equipment is generally used with a spiral drill bit. During the soil discharge process, the pit wall will be squeezed, resulting in the compaction of the soil inside the pre-buried pit. The soil needs to be loosened before pre-buried, and the backfilled soil may be mixed with gravel, etc. The operator needs to simply screen it out to avoid the loss of the roots and stems of green plants. For this reason, we propose a pit digging equipment for greening planting to solve the above problems. Utility Model Content

[0026] A loosening board 3 and a rotating plate 24 are installed at the bottom of the telescopic rod 22. The loosening board 3 is arranged on the outside of the rotating plate 24. The loosening boards 3 are arranged in a uniform array on the outside of the rotating plate 24. When it is necessary to transplant vegetation, digging equipment can be used to dig holes. As the spiral shaft rotates with the telescopic rod 22, the soil can be quickly discharged. Under the action of the loosening board 3, the inner wall of the pit can be processed to avoid the situation where the internal soil is too compacted and airtight.

[0027] A circular groove is provided on the surface of the rotating plate 24, and the spiral shaft is located inside the circular groove. A separation ring 25 is installed at the bottom of the rotating plate 24. The bottom of the separation ring 25 is conical, and a plurality of separation grooves are provided at the bottom of the separation ring 25. A fixed sieve ring 26 is installed on the side wall of the separation ring 25. After the discharge of the pit soil and the like is completed, the spiral shaft is reset, so that the bottom of the separation ring 25 can contact with the side wall of the pit, and the compacted soil can be quickly pushed down.

[0028] A plurality of positioning rods 251 are provided inside the separation ring 25. The positioning rods 251 are movably inserted inside the rotating plate 24. The bottom of the positioning rods 251 is arc-shaped, and a swing ball is installed on the top of the positioning rods 251. After the pit is opened, the telescopic rod 22 is reset and rotated at the same time, and the operator can put the excavated soil into the separation ring 25, which can make it perform centrifugal motion inside the separation ring 25. Under the action of the positioning rods 251, large particles of debris and stones are separated to prevent them from remaining in the soil. At the same time, it plays the role of loosening the soil, which can ensure that a certain gap remains in the soil after subsequent backfilling, thereby increasing the survival rate of green plants.

[0029] A positioning ring 23 is installed at the bottom of the positioning plate 21, and a plurality of compression shafts 231 are fixedly connected to the bottom of the positioning ring 23. The compression shaft 231 is "U"-shaped and elastic. The position of the compression shaft 231 corresponds to the swinging ball, which can make the bottom of the compression shaft 231 and the swinging ball squeeze and rub against each other, and can drive the positioning rod 251 to swing, thereby improving the separation efficiency of the soil.

[0032] Working principle: First, when it is necessary to transplant vegetation, the pit can be dug with the help of the pit digging equipment. As the spiral shaft rotates with the telescopic rod 22, the soil can be quickly discharged, and under the action of the loosening board 3, the inner wall of the pit can be processed to avoid the situation where the internal soil is too compacted and airtight. The bottom position of the spiral shaft is lower than the separation ring 25, and it can contact the soil first. As the telescopic rod 22 pushes the equipment to feed, after the soil is discharged, the spiral shaft is reset, so that the bottom of the separation ring 25 can contact with the side wall of the pit, and the compacted soil can be quickly pushed down. At the same time, the loosening board 3 can The operator makes a circular motion to dig the soil inside the pit. With the help of the compression plate 32, the residual roots on the inner wall of the pit can be torn off to avoid residual vegetation and weeds. After the pit is dug, the telescopic rod 22 is reset and rotated at the same time, and the operator can put the dug soil into the separation ring 25, which can make it move centrifugally inside the separation ring 25. Under the action of the positioning rod 251, large particles of debris and stones are separated to avoid them remaining in the soil. At the same time, it plays the role of loosening the soil, which can ensure that there is a certain gap left in the soil after subsequent backfilling, thereby increasing the survival rate of green plants.
