[0037] See also Figure 1-Figure 6 Now, a soil fine screening device specially used for reclaiming cultivated land provided by an embodiment of the utility model is described.
[0038] In one embodiment, a soil fine screening device for cultivated land of the utility model embodiment comprises a plow frame 6, a fixed frame 1, a screen frame 2, a crushing mechanism 4 and a comb frame 3. One end of the fixed frame 1 is connected to the plow frame 6; the screen frame 2 is connected to the other end of the fixed frame 1; the crushing mechanism 4 is arranged in the screen frame 2; the comb frame 3 is rotatably connected to the screen frame 2; the comb frame 3 is arranged between the plow frame 6 and the screen frame 2, the comb frame 3 is inclined toward the plow frame 6, and the comb frame 3 includes a plurality of comb teeth arranged at intervals.
[0039] The plow frame 6 of this embodiment is used for land reclamation. The plow frame 6 can adopt a conventional existing structure, and this embodiment does not limit the structure of the plow frame 6.
[0040] A soil fine screening device specially used for reclaimed arable land in the present embodiment is provided by fixing a fixing frame 1 on a plow frame 6, and placing a comb frame 3 behind the plow frame 6, while the comb frame 3 is tilted toward the plow frame 6. The inclination angle of the comb frame 3 can be controlled by rotating the comb frame 3 so that the lower end of the comb frame 3 can be inserted into the soil after the plow frame 6 has turned the soil, and then the large-grained stones and clods in the soil are screened by the comb frame 3, and particles larger than the gaps between the comb teeth of the comb frame 3 remain on the comb frame 3, while small particles fall through the gaps of the comb frame 3. Afterwards, the comb frame 3 is rotated in the opposite direction so that the end of the comb frame 3 close to the screen frame 2 is the low point, and the large particles of stone and soil on the comb frame 3 slide into the screen frame 2, and the large particles in the screen frame 2 are crushed by the crushing mechanism 4, and the crushed particles fall below through the gap of the screen frame 2. At the same time, when the crushing mechanism 4 hits the stone during the crushing process, the soil adhered to the surface of the stone can be knocked off, thereby realizing the simultaneous screening of soil during the reclamation process, improving the reclamation efficiency, eliminating the need for secondary screening, and achieving the technical effect of reducing manpower and material resources.
[0041] Furthermore, the soil fine screening device for cultivated land of this embodiment further comprises two symmetrically arranged hydraulic cylinders 5, one end of the cylinder body of the hydraulic cylinder 5 is rotatably connected to the screen frame 2, and one end of the piston rod of the hydraulic cylinder 5 is rotatably connected to the comb frame 3. In this way, when in use, the comb frame 3 can be driven to rotate by the extension and contraction of the piston rod of the hydraulic cylinder 5, so as to realize the control of the inclination angle of the comb frame 3.
[0042] Further, in this embodiment, the comb frame 3 is fixedly mounted with a first shaft 301 and a second shaft 302 at one end, and the third shaft 2013 is fixedly mounted on both sides of the screen frame 2. The first shaft 301 is rotatably connected to the screen frame 2, the second shaft 302 is rotatably connected to the piston rod of the hydraulic cylinder 5 through a bearing, and the third shaft 2013 is rotatably connected to the cylinder body of the hydraulic cylinder 5 through a bearing. In this way, when the hydraulic cylinder 5 is telescopically adjusted, the comb frame 3 deflects with the first shaft 301 as the axis, and the hydraulic cylinder 5 rotates with the second shaft 302 and the third shaft 2013 during this process to avoid interference.
[0043] Furthermore, the inner side wall of the screen frame 2 of the present embodiment is in an inwardly concave arc shape, and the screen frame 2 includes two symmetrically arranged side plates 201 and a plurality of spaced round rods 202 connected between the two side plates 201. In this way, after the large pieces of soil or gravel particles coming from the screen frame 3 are crushed by the crushing mechanism 4, they slide down along the inner side wall of the screen frame 2, and the fine particles fall from the gaps between the round rods 202, while the larger particles slide to the bottom of the screen frame 2. Furthermore, the gap between two adjacent round rods 202 is smaller than the gap between two adjacent comb teeth of the comb frame 3, so as to prevent the smaller stones mixed in the soil from falling or the stones crushed by the crushing mechanism 4 from falling out, so as to facilitate secondary and finer screening.
[0044] Furthermore, the bottom of the screen frame 2 of this embodiment is also provided with a plurality of long screws 203 arranged at intervals, and the long screws 203 are detachably connected to the screen frame 2. In this way, when it is necessary to remove the larger-grained stones at the bottom of the screen frame 2, after the long screws 203 are removed from the screen frame 2, a stone discharge port 2021 is formed at the bottom of the screen frame 2, and the larger-grained stones are discharged from the stone discharge port 2021 to clean the screen frame 2.
[0045] Further, the two side plates 201 of the present embodiment are respectively provided with a plurality of mounting holes 2011 and a plurality of threaded holes 2012, one end of the long screw 203 is threadedly connected in the threaded hole 2012, and the other end is penetrated in the mounting hole 2011. The mounting hole 2011 is a through hole and a non-threaded hole, so that when it is necessary to remove the large-grained stone at the bottom of the screen frame 2, the long screw 203 is rotated counterclockwise from the threaded hole 2012 and pulled out from the mounting hole 2011, and a stone discharge port 2021 is formed at the bottom of the screen frame 2, so as to clean out the stones in the screen frame 2. It should be noted that the mounting hole 2011 can also be a threaded hole, and designing it as a non-threaded hole can make it more convenient and faster to remove the long screw 203 from the screen frame 2.
[0046] Furthermore, the gap between two adjacent long screws 203 of this embodiment is smaller than the gap between two adjacent comb teeth of the comb frame 3, so as to prevent smaller stones mixed in the soil blocks from falling or stones crushed by the crushing mechanism 4 from falling out, so as to facilitate secondary and finer screening.
[0047] Further, the crushing mechanism 4 of this embodiment includes a motor 403 fixed on the screen frame 2 and a stirring shaft 401 rotatably connected in the screen frame 2, the motor 403 drives the stirring shaft 401 to rotate, and a plurality of crushing rods 402 are connected to the stirring shaft 401 at intervals along the length direction of the stirring shaft 401. The plurality of crushing rods 402 can be vertically connected to the stirring shaft 401. Specifically, the motor 403 of this embodiment is fixed on a side plate 201 of the screen frame 2, and the two ends of the stirring shaft 401 are respectively rotatably connected to the two side plates 201, and the output shaft of the motor 403 is coaxially fixed with the stirring shaft 401. After the larger particles of stone or soil fall into the screen frame 2, the motor 403 drives the stirring shaft 401 to rotate, and the stirring shaft 401 drives the crushing rod 402 to hit the stone or soil in the screen frame 2 and break it, and at the same time hit the stone or soil, so that the soil adhered to the stone falls off.
[0048] Further, the fixing frame 1 of the present embodiment includes two symmetrically arranged fixing rods 101, one end of each fixing rod 101 is provided with two clamping plates 102, and the clamping plates 102 are provided with multiple groups of bolt and nut groups 103; one end of the fixing rod 101 is fixed to the plow frame 6 through the clamping plates 102, and the other end is fixedly connected to the screen frame 2. Specifically, the fixing rod 101 is fixed to one of the clamping plates 102, and the two clamping plates 102 are clamped on the plow frame 6, and then the two clamping plates 102 are fixed to the plow frame 6 through the bolt and nut group 103, and the bolts of the bolt and nut group 103 pass through the clamping plates 102, thereby fixing the comb frame 3 and the screen frame 2 to the plow frame 6. The other end of the fixing rod 101 is fixed to the side plate 201 of the screen frame 2.
[0049] The soil fine screening device for cultivated land in this embodiment works as follows: two clamping plates 102 are clamped on the plow frame 6, and the bolt and nut group 103 are fastened to the two clamping plates 102 by a wrench to fix the fixing frame 1 on the plow frame 6. The hydraulic cylinder 5 is telescopically adjusted so that the lower end of the comb frame 3 can be inserted into the soil after the plow frame 6 turns the soil. The plow frame 6 follows the plowing machine to turn the soil. The soil after turning the soil is screened by the comb frame 3. Large clods of soil and stones are intercepted on the comb frame 3, and the comb frame 3 is stretched with the first shaft 3 by the extension of the hydraulic cylinder 5. 01 is an axis that flips upward, so that the soil and stones on the comb frame 3 slide into the screen frame 2, and then the motor 403 drives the stirring shaft 401 to rotate, and the stirring shaft 401 drives the breaking rod 402 to hit the stones and soil in the screen frame 2, and break the soil, and at the same time hit the stones, so that the mud adhering to the stones falls off, and the screen frame 2 performs secondary fine screening, and finally the long screw 203 is removed counterclockwise from the threaded hole 2012 and pulled out from the mounting hole 2011. At this time, a stone discharge port 2021 is formed at the bottom of the screen frame 2 to facilitate the discharge and cleaning of the stones at the bottom of the screen frame 2.
[0050] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
