Description

Technical Field

[0001] The present application relates to the technical field of land reclamation in mining areas, and in particular to a land reclamation device for coal mining subsidence areas. Background Art

[0002] Coal mining subsidence areas are land that has sunk, collapsed and been damaged during the coal mining process. In subsidence areas, especially those with perennial waterlogging, the damage to the arable land is permanent, so restoration measures are needed to restore the arable land in coal mining subsidence areas.

[0003] At present, the land reclamation plans for coal mining subsidence areas all involve the backfilling of coal gangue. In land reclamation, a plow tool that breaks up the soil is used to cultivate the surface of the soil. Since the surface of the soil is mixed with a large amount of coal gangue and other stones, some larger stones will be stuck between the plowboards. Therefore, after a long period of cultivation, the reclamation effect of the soil layer mixed with coal gangue will be reduced. Utility Model Content

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The embodiment of the present application discloses a land reclamation device for coal mining subsidence areas.

[0028] refer to Figure 1 and Figure 2 The land reclamation device for coal mining subsidence area includes a main board 1, a plowboard 2, a cleaning rod 3, a connecting rod 31 and a pull-out rod 33. There are multiple plowboards 2, which are fixed on the lower surface of the main board 1 at equal intervals, and the bottom is a bent tip structure. There are multiple cleaning rods 3, which are rotatably connected to the lower surface of the main board 1 and located between the plowboards 2. The connecting rod 31 is fixedly connected to one end of the multiple cleaning rods 3 away from the plowboard 2. A torsion spring is installed at the rotating shaft of the cleaning rod 3, so that the cleaning rod 3 rotates toward the main board 1. When the cleaning rod 3 is in a horizontal state, it is tilted downward from both ends to the middle part, and then extends horizontally. The horizontally extended part is the cleaning part 32. The main board 1 is provided with a fixing component 4 for fixing the position of the connecting rod 31 when the cleaning rod 3 rotates to a horizontal state. The connecting rod 31 is rotatably connected with a pull-out rod 33, which is detachably fixed to the bottom of the main board 1. When the cleaning rod 3 is in a horizontal state, the pull-out rod 33 is rotated to a horizontal state and extends from below the main board 1. The pull-out rod 33 is provided with a clamping assembly 5 for fixing the pull-out rod 33 to the main board 1. After the cleaning rod 3 is rotated downward, the cleaning portion 32 can pass through the position between the moldboards 2, and both sides of the cleaning portion 32 can abut against the side walls of the moldboard 2.

[0029] When it is necessary to clean the gangue and other stones stuck between the moldboards 2, the fixing of the connecting rod 31 is released by the fixing assembly 4, and then the fixing of the pull-out rod 33 is released by the clamping assembly 5, and then the cleaning rod 3 is driven to rotate by pulling the pull-out rod 33, and the connecting rod 31 can drive multiple cleaning rods 3 to rotate together, so that the cleaning part 32 passes between the moldboards 2, and cleans the stones between the moldboards 2, and scrapes the soil on the moldboards 2, thereby improving the efficiency of cleaning and maintaining the moldboards 2. The shape of the cleaning plate can facilitate the cleaning part 32 to pass through the position between the moldboards 2, and improve the cleaning effect of the moldboard 2. The setting of the torsion spring can facilitate the cleaning plate to remain in a horizontal state and be placed under the main board 1, so as not to affect the normal use of the moldboard 2. The setting of the pull-out rod 33 can facilitate the cleaning plate to rotate together.

[0030] refer to Figure 2 The fixing assembly 4 includes a sliding rod 41, a buckling plate 42 and a fixing bolt 43. There are multiple sliding rods 41, which are slidably connected to the upper surface of the main board 1. The buckling plate 42 is fixedly connected to the ends of the multiple sliding rods 41 away from the plowboard 2, and the buckling plate 42 is set downward. The buckling plate 42 is provided with a fixing hole 421 at a position opposite to the side wall of the main board 1, and the side wall of the main board 1 is provided with a fixing groove 11 connected to the fixing hole 421, and the fixing bolt 43 can pass through the fixing hole 421 and be threadedly connected to the fixing groove 11. At this time, the buckling plate 42 can be tightly fixed to the connecting rod 31 when the cleaning rod 3 is rotated to a horizontal state.

[0031] After rotating the cleaning rod 3 to a horizontal state, slide the arc retaining plate 42 so that the arc retaining plate 42 is tightly pressed against the connecting rod 31, and then rotate the fixing bolt 43 so that the fixing bolt 43 is threadedly connected to the fixing groove 11, and the fixing bolt 43 installs the arc retaining plate 42 on the main board 1, thereby completing the position fixation of the cleaning rod 3 and improving the efficiency of position fixation of the cleaning rod 3.

[0032] refer to Figure 3 and Figure 4 The clamping assembly 5 includes a locking rod 51 and a clamping plate 52. A spring groove 331 is provided at one end of the pull-out rod 33 away from its own rotation axis, and a limiting groove 332 is provided on the inner wall of the spring groove 331. The locking rod 51 is slidably connected in the spring groove 331, and a limiting ring plate 511 is fixed on the outer wall of the locking rod 51. A locking spring 512 is fixed on one end of the limiting ring plate 511 facing the opening of the spring groove 331, and the other end of the locking spring 512 is fixedly connected to the inner wall of the limiting groove 332. The clamping plate 52 is fixedly arranged at one end of the locking rod 51 away from the connecting rod 31, and the locking spring 512 can make the clamping plate 52 cling to the upper surface of the end of the main board 1 and press against the main board 1.

[0033] After the pull-out rod 33 is in a horizontal state, the clamping plate 52 is pulled out and rotated to the end of the main board 1. After the clamping plate 52 is released, the clamping plate 52 is clamped with the end of the main board 1, and then the pull-out rod 33 is fixed under the main board 1, thereby improving the efficiency and stability of fixing the main board 1.

[0034] The implementation principle of a land reclamation device for coal mining subsidence areas in an embodiment of the present application is as follows: when it is necessary to clean the stones and soil between the moldboards 2, rotate the fixing bolt 43 to separate the fixing bolt 43 from the fixing groove 11, then slide the sliding rod 41 to separate the arc plate 42 from the connecting rod 31, release the fixation of the connecting rod 31, then pull the clamping plate 52 and the pull-out rod 33 to drive multiple cleaning rods 3 to rotate together, so that the cleaning part 32 passes through the position between the moldboards 2 to clean the stones and coal gangue stuck between the moldboards 2, and scrape the soil between the moldboards 2, thereby improving the efficiency of cleaning and maintaining the moldboards 2, and thereby improving the effect of the reclamation plow device on the long-term reclamation of the soil layer mixed with coal gangue.

[0035] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
