Description

Technical Field

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

[0002] Landscaping refers to the arrangement of gardens in a certain area through engineering and artistic means. In the construction of landscaping projects, it is often necessary to plant trees. At this time, machinery and equipment are needed to dig holes in the garden land and plant trees.

[0003] For example, the publication number CN220402321U discloses a tree planting and digging equipment for landscaping engineering construction. The device only needs to place the entire auger in the digging area, then start the motor, and press the handle by hand to make the entire device dig the hole downward. The damping fluid is used to offset the impact force generated, so that the entire handle will not vibrate significantly, thereby avoiding numbness of the workers' hands during the digging process.

[0004] However, the practicality of the pit digging equipment is poor when in use. The pit digging equipment is not provided with a positioning structure to fix the ground drill when in use. Instead, the hand needs to press the handle to make the whole device dig a pit downward. Although there will be no large-scale vibration, the ground drill will still shake, resulting in deviation when digging a pit, and it is troublesome to press it manually. When the staff uses it for a long time, their hands will become numb, which affects the efficiency of subsequent planting and digging. In view of this, we propose a pit digging device with a positioning mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a pit digging device with a positioning mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a digging device with a positioning mechanism, comprising a top plate, U-shaped plates are fixedly installed on both sides of the lower end of the top plate, a digging structure is arranged in the middle of the lower end of the top plate, and a positioning structure is arranged inside the top plate, and the positioning structure includes:

[0009] Preferably, the support structure includes a support plate fixedly mounted on the side wall of the U-shaped plate, a first airbag is fixedly mounted on the upper end of the support plate, a second airbag is fixedly mounted on the lower end of the support plate, and an anti-skid plate is fixedly mounted on the lower end of the second airbag.

[0010] Preferably, the upper end of the first airbag is fixedly connected to the lower end of the connecting plate, and the first airbag and the second airbag are connected via two sets of ventilation pipes.

[0011] Preferably, the interior of the second airbag is filled with half of the gas volume, and the interior of the first airbag is in a state of sufficient gas volume.

[0013] Preferably, one end of the return spring is fixedly connected to the inner wall of the slide groove, and the other end of the return spring is fixedly connected to the side wall of the sleeve.

[0014] Compared with the prior art, the utility model provides a pit digging device with a positioning mechanism, which has the following beneficial effects:

[0015] 1. The digging device with a positioning mechanism is convenient for fixing and supporting the digging structure by setting a positioning structure. When the user is digging a pit, the double-headed cam can be driven to rotate by starting the motor. The rotation of the double-headed cam drives the two sets of contact plates to move outward relative to each other, thereby driving the slider and the connecting block to move downward. The downward movement of the connecting plate drives the fixing nail to move, and the fixing nail is inserted into the ground to position the device and fix it, thereby preventing shaking and deviation during subsequent digging that affects use.

[0016] 2. The digging device with a positioning mechanism is provided with a supporting structure so as to facilitate the support and fixation of the bottom of the U-shaped plate. The downward movement of the connecting plate will squeeze the first airbag. When the first airbag is squeezed, the gas inside it will enter the second airbag through the ventilation pipe, so that the second airbag will expand and drive the anti-skid plate to move downward and support the ground, thereby further improving the stability of the device.

[0024] Specifically, the positioning structure 3 of the technical solution of the utility model includes: a cavity 31, a moving block 32, a contact plate 33, a motor 34, a double-headed cam 35, a connecting plate 36, a fixing pin 37, a notch 38, a slider 39, a connecting rod 310, and a connecting block 311.

[0025] In one embodiment of the utility model, a positioning structure 3 is provided to facilitate fixed support of the digging structure 5. Before planting the land inside the garden, the user can move the device as a whole to reach the designated position for digging. When digging, the user can align the digging structure 5 at the lower end of the top plate 1 with the digging point, and then start the motor 34 to drive the double-headed cam 35 on its surface to rotate. When the double-headed cam 35 rotates, it will contact and squeeze the two sets of contact plates 33.
