Description

Technical Field

[0001] The present application relates to the field of forestry technology, and more specifically, to a convenient pit digging device for forestry planting. Background Art

[0002] In forestry tree planting, due to the large planting area, manual digging is not only inefficient, but also seriously affects the speed and quality of afforestation.

[0003] A document with prior art disclosure (announcement) number CN215073831U provides a digging device for planting forestry plants. In the related technology of the device, the first L-shaped rod, the first rotating shaft, and the first bevel gear cooperate with each other, so that the device can be rotated to achieve operations in multiple directions, so that the device can be applied to multiple scenes, improving work efficiency. In addition, the spring, the second L-shaped rod, and the first movable plate cooperate with each other, so when digging a pit, there is no need to manually lift the pressing plate. The spring will automatically pull the digging knife out of the pit, saving human resources.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the digging knife drills the ground to dig a hole, it will be squeezed with the soil layer, and the lifting and resetting of the digging knife is only achieved by a spring, and the sensitivity of the lifting and resetting response is poor.

[0005] In view of this, we propose a convenient pit digging device for forestry planting. Utility Model Content

[0006] In order to improve the problems raised in the above background technology, the present application provides a convenient pit digging device for forestry planting.

[0042] The push rod 7 is fixedly mounted on one end of the driving frame 1 and can abut against a positive and negative opening and closing switch mounted on one side of the lifting platform 2 to limit the position.

[0043] The convenient pit digging device for forestry planting utilizes the diesel driving engine 3 to rotate the drill paddle 4. The working diesel driving engine 3 meshes and transmits with the speed change gear 6 through the transmission gear 31 installed on the outside of its driving shaft, so that the speed change gear 6 drives the lifting platform 2 to achieve the lifting action along the trajectory of the threaded shaft 5, and the pit drilling operation of the drill paddle 4 is realized. After the lifting platform 2 moves down to a certain position, it can be squeezed with the top rod 7 installed at one end of the driving frame 1, so that the diesel driving engine 3 installed with the clutch can be opened and closed in both directions, and the drill paddle 4 can be automatically lifted and lowered, thereby improving the drilling efficiency of the device.

[0044] Reference Figure 3 and Figure 4In the convenient pit digging device for forestry planting recorded in the embodiment of the present application, a retaining column 11 is fixedly connected to one side of the driving frame 1, and two rows of soil propellers 12 are rotatably connected to one side of the retaining column 11. The two rows of soil propellers 12 are adapted for transmission through a sprocket structure, and one row of soil propellers 12 is connected to an extrusion shaft 13 through a bevel gear structure. The extrusion shaft 13 passes through the lifting platform 2 and is rotatably connected to one side of the driving frame 1, and the extrusion shaft 13 with a spiral extrusion groove is adapted for sliding extrusion outside and is equipped with an extrusion sleeve 14. The extrusion sleeve 14 is fixedly installed on one side of the lifting platform 2, and a plurality of cylinders 15 are threadedly installed on one side of the driving frame 1, and a ground cone 16 is slidably adapted in the cylinder 15, and the ground cone 16 and the cylinder 15 are elastically connected and limited by a spring.

[0045] The convenient pit digging device for forestry planting utilizes the lifting platform 2 to limit the lifting action, thereby driving the extrusion sleeve 14 and the extrusion shaft 13 to slide and extrude and adapt, so that the rotating extrusion shaft 13 drives the soil discharge propeller 12 to transmit, thereby discharging the soil thrown out by the drill paddle 4 when drilling the pit, thereby ensuring the use of the drill paddle 4 for digging the pit, and the ground cone 16 can enhance the stability between the driving frame 1 and the ground, thereby ensuring the stability of the device for digging the pit, and the elastically connected ground cone 16 can ensure elastic contraction when it comes into contact with the cement ground, thereby realizing the convenience of placing the driving frame 1.

[0046] Reference Figure 5 and Figure 1 In the convenient pit digging device for forestry planting recorded in the embodiment of the present application, a through hole is opened on one side of the lifting platform 2, and two closing plates 21 are symmetrically threadedly connected in a circular structure. A reel 22 is elastically rotatably connected between the two closing plates 21 through a coil spring. A retaining belt 23 is wound around the outside of the reel 22, and the other end of the retaining belt 23 passes through the lifting platform 2 and is fixedly connected to the side of the retaining column 11, and a slot is opened on one side of the lifting platform 2, and a soft brush plate 24 capable of cleaning the retaining belt 23 is inserted and installed in the slot with a T-shaped structure.

[0047] The convenient pit digging device for forestry planting uses the lifting platform 2 to limit the lifting and lowering to roll up the retaining belt 23, thereby ensuring the water-blocking effect of the retaining belt 23, and the soft-bristle brush plate 24 cleans the retaining belt 23, which can effectively ensure the aesthetics of the retaining belt 23 when rolled up and stored.

[0048] Working principle: When the operator presses the forward switch of the forward and reverse opening and closing switch installed on one side of the lifting platform 2, the diesel driving engine 3 drives the connected and fixed drill paddle 4 to rotate, and the rotating diesel driving engine 3, under the action of the transmission gear 31, drives the meshing and matching speed change gear 6 to rotate at a low speed;

[0049] At this time, the speed change gear 6 rotating at a low speed is threadedly adapted along the track of the threaded shaft 5, and drives the lifting platform 2 to move downward within a limited position, so as to realize the drilling operation between the drill bit paddle 4 and the soil layer;

[0050] At the same time, the downwardly moved lifting platform 2 is slidably and extruded with the extrusion shaft 13 under the action of the extrusion sleeve 14, so that the rotating extrusion shaft 13 drives the soil discharge propeller 12 of the meshing transmission adaptation to rotate, and the soil rotated upward by the drill bit paddle 4 is discharged, and the downwardly pressed lifting platform 2 drives the elastically released reel 22 to reel in the retaining belt 23;

[0051] When it moves down to a certain position along the track of the driving frame 1, the push rod 7 installed at one end of the driving frame 1 squeezes the reverse rotation switch of the forward and reverse opening and closing switch, so that the diesel driving engine 3 installed with the clutch rotates in the opposite direction, pushing the lifting platform 2 to move up and driving the drill paddle 4 to return to its position.
