[0026] Example

[0027] See also Figure 1-5 The utility model provides a technical solution: a Luoyang shovel with an anti-drop function, comprising a shovel blade 1, a sealing plate 5 is fixed on the top of the shovel blade 1, a connecting cap 7 is fixed on the top of the sealing plate 5, a shovel rod 8 is connected to the top of the connecting cap 7, a placement groove 3 is opened on one side of the shovel blade 1, a shovel blade inner plate 2 is connected to the inner side of the placement groove 3, and a plurality of arc-shaped anti-drop plates 4 are fixed on one side of the shovel blade inner plate 2. The worker holds the shovel rod 8 and inserts the shovel blade 1 into the soil with force. When the shovel blade 1 is inserted into the soil, the soil remains on the top of the arc-shaped anti-drop plates 4 when passing through the tops of the plurality of arc-shaped anti-drop plates 4. A connecting component 6 is provided on one side of the sealing plate 5;

[0028] The connecting assembly 6 includes a second slide plate 66, a slide groove 67 is provided inside the sealing plate 5, a plurality of first slide plates 64 are fixed on one side of the second slide plate 66, a locking column 62 which passes through one side of the bottom of the sealing plate 5 is fixed at the bottom of the first slide plate 64, and the pull ring 61 is pulled upward to compress the spring 65, and at the same time, the first slide plate 64 and the plurality of second slide plates 66 slide on the inner side of the slide groove 67 at the same time, a plurality of first limiting grooves 63 are provided on the top of the scraper inner plate 2, the outer side of the locking column 62 is adapted to the inner side of the first limiting groove 63, and the plurality of locking columns 62 leave the inner side of the first limiting groove 63, and at this time, the scraper inner plate 2 is pulled toward the side away from the placement groove 3, so that the scraper inner plate 2 can be conveniently removed for replacement.

[0029] A support rod 610 that is movable and runs through the top of the sealing plate 5 is fixed to the top of the second slide 66, and a pull ring 61 is fixed to the top of the support rod 610. The outer sides of the first slide 64 and the second slide 66 are slidably connected to the inner side of the slide groove 67. Several springs 65 are connected between the tops of the first slide 64 and the second slide 66 and the inner side walls of the slide groove 67. This avoids the need for workers to carry extra tools such as screwdrivers when collecting soil in the field. Workers only need to pull up the pull ring 61 to conveniently replace the blade inner plate 2, thereby improving the convenience of the Luoyang shovel during maintenance.

[0030] A second limiting groove 69 is opened at the bottom of the blade inner plate 2, and a limiting block 68 adapted to the inner side of the second limiting groove 69 is fixed to the bottom of the inner wall of the placement groove 3. The second limiting groove 69 at the bottom of the blade inner plate 2 is aligned with the limiting block 68 and inserted. Then, the blade inner plate 2 is rotated with the limiting block 68 inserted in the second limiting groove 69 as a fulcrum, so that the top of the blade inner plate 2 is located at the lower side of the locking column 62, and then the blade inner plate 2 is continued to be pushed so that multiple locking columns 62 are inserted into the inner side of the first limiting groove 63, and the outer side of the blade inner plate 2 is adapted to the inner side of the placement groove 3, and the installation of the blade inner plate 2 is completed.

[0031] Working principle: When the Luoyang shovel is needed, the worker only needs to hold the shovel rod 8 and forcefully insert the shovel blade 1 into the soil. When the shovel blade 1 is inserted into the soil, the soil passes through the top of multiple arc-shaped anti-drop plates 4, and the soil remains on the top of the arc-shaped anti-drop plates 4. When the shovel rod 8 is pulled upward, the soil inside the arc-shaped anti-drop plates 4 will not fall, which is convenient for workers to use the Luoyang shovel to sample the soil.

[0032] When the arc-shaped anti-drop plate 4 is inserted into the soil multiple times, causing the sharp edge of the arc-shaped anti-drop plate 4 to wear and unable to retain the soil well, it is only necessary to pull the pull ring 61 upwards to compress the spring 65, and at the same time make the first slide plate 64 and multiple second slide plates 66 slide on the inner side of the slide groove 67 at the same time, so that multiple locking columns 62 leave the inner side of the first limiting groove 63. At this time, pull the shovel inner plate 2 to the side away from the placement groove 3, and the shovel inner plate 2 can be easily removed and replaced. The operation is simple and easy to use, avoiding the need for workers to carry additional tools such as screwdrivers when collecting soil in the field. Only the pull ring 61 is pulled upwards to easily replace the shovel inner plate 2, thereby improving the convenience of the Luoyang shovel during maintenance.

[0033] When a new blade inner plate 2 needs to be installed, it is only necessary to align the second limit groove 69 at the bottom of the blade inner plate 2 with the limit block 68 and then rotate the blade inner plate 2 with the limit block 68 inserted in the second limit groove 69 as a fulcrum so that the top of the blade inner plate 2 is located on the lower side of the locking column 62. Then continue to push the blade inner plate 2 so that multiple locking columns 62 are inserted into the inner side of the first limit groove 63. At this time, the blade inner plate 2 can be easily installed.
