It should be noted that the friction between the slide plate 33 and the limit slider 34 is relatively large, so that when the circular ring plate 28 rotates, it will drive the hinge rod 32, the first connecting plate 31, the disk 30, the second spline shaft 27, and the second spline shaft sleeve 25 to rotate synchronously. The second bearing plate 38 and the third bearing circular plate 39 are both heavy plates, so that when the second spline shaft sleeve 25 and the second spline shaft 27 rotate, the circular ring plate 28 will not be driven to rotate.

Each time the prismatic turning plate 37 rotates a preset angle, the prismatic turning plate 37 moves back and forth to the left to turn the sludge horizontally. Then the prismatic turning plate 37 is extended to a certain length to the left, so that the prismatic turning plate 37 is placed on the front side of the sludge, and then the prismatic turning plate 37 is swung left and right to push the sludge longitudinally, and then retreated. Then the prismatic turning plate 37 is extended to a longer position, so that the prismatic turning plate 37 is swung left and right, and the sludge is pushed longitudinally at multiple positions, so that the sludge is turned over well and broken, loosened, and the water vapor is better discharged. It is noted that the prismatic soil turning plate 37 is also required to be placed at the rear side of the sludge to swing forward longitudinally and push so that the sludge is better broken up and turned over. It is noted that the action of the prismatic soil turning plate 37 placed at the rear side of the sludge is to rotate in the opposite direction to the rear side of the sludge without passing through the sludge. After the drying and breaking up is determined, the prismatic soil turning plate 37 is allowed to continue to swing longitudinally, and the final position of the swing exceeds the position of the sludge conveyor belt 10, so that the hard stones in it are pushed to the front or rear side of the sludge conveyor belt 10, so that the dried sludge can be directly used as nutrient soil without the need to screen out the hard stones again.

[0034] In summary, the prismatic soil turning plate 37 will first break up the sludge, turn over, and loosen the soil, and prevent the soil from being separated from the sludge conveyor belt 10, so that the sludge is dried quickly. The second step is to push the hard stones in the dried and broken sludge out of the sludge conveyor belt 10.

The first mounting plate 9 is upper limit rotationally connected with three first spline shafts 16, and the outer walls of the three first spline shafts 16 are all fixedly connected with belt matching gears, and the three belt matching gears are jointly sleeved with gear matching belts 17, so that the three first spline shafts 16 rotate synchronously, and the outer walls of the three first spline shafts 16 are all upper and lower limit slidingly connected with the first spline sleeves 19, and the outer walls of the three first spline sleeves 19 are all fixedly connected with the first gear 20, and the outer walls of the three first spline sleeves 19 are limited rotationally connected with the first bearing plate 18, and three electric telescopic rods 40 are fixedly installed on the first mounting plate 9, and the three electric telescopic rods 40 are connected to the first bearing plate 18.

[0042] The controller is provided with a plurality of control buttons and a display screen. The controller is electrically connected to the electric telescopic rod 40, the heating wire 41, the second motor 15, the first motor 14, and the blower 5 for controlling the operation of the device.

[0043] The other structures are the same as those in the second embodiment.

[0044] In this embodiment, the sludge is firstly made to enter the inclined material guide frame 3 from the feed port 13 and is transferred to the sludge conveyor belt 10. It is noted that the sludge transferred to the sludge conveyor belt 10 by the inclined material guide frame 3 is only distributed in the middle of the sludge conveyor belt 10 and is transferred in the middle of the sludge conveyor belt 10. The frame groove of the inclined material guide frame 3 is not larger than half of the width of the sludge conveyor belt 10, and the inclined material guide frame 3 is placed at the middle top of the sludge conveyor belt 10.

[0045] When the sludge is being conveyed, the switches of the heating wire 41 and the blower 5 are first turned on so that high-temperature gas is blown into the working box 1 to perform a drying operation.

[0046] When the sludge is conveyed to the preset position of the sludge conveyor belt 10, the rightmost electric telescopic rod 40 is moved downward, and the rightmost first gear 20 and the second gear 21 are meshed with each other. The first motor 14 is started to lower the annular plate 28 and the prismatic turning plate 37 to the preset height. Then, due to the effect of the thread, the position of the prismatic turning plate 37 will not change easily. That is, the height adjustment of the prismatic turning plate 37 is completed.

[0047] Then the rightmost electric telescopic rod 40 is lifted upward, so that the rightmost first gear 20 and the second gear 21 are no longer meshed. The middle electric telescopic rod 40 is retracted downward so that the middle first gear 20 and the second gear 21 are meshed with each other, so that the prismatic soil turning plate 37 moves back and forth horizontally to the left and right, and the sludge on the sludge conveyor belt 10 is turned and scattered, so as to facilitate drying. Then the middle electric telescopic rod 40 is lifted upward, the meshing of the middle first gear 20 and the second gear 21 is released, and the leftmost first gear 20 and the second gear 21 are meshed with each other, so that the annular plate 28 rotates a preset angle. Then the leftmost first gear 20 and the second gear 21 are released, and the middle first gear 20 and the second gear 21 are meshed, so that the prismatic soil turning plate 37 pushes the sludge back and forth horizontally to the left at different angles, so that the sludge on the left is pushed to turn the soil in multiple positions horizontally, so that the sludge is turned and dried relatively well.

[0048] After the leftward lateral push is completed, the first gear 20 and the second gear 21 in the middle are meshed, so that the prismatic turning plate 37 moves a preset length. Then the first gear 20 and the second gear 21 in the middle are released from meshing, so that the first gear 20 and the second gear 21 on the far left are meshed, and the prismatic turning plate 37 swings left and right to perform longitudinal swing turning. It should be noted that the prismatic turning plate 37 will not move beyond the position of the sludge conveyor belt 10 to prevent the sludge from being pushed outside the sludge conveyor belt 10. By continuously moving the position of the prismatic turning plate 37 relative to the slide plate 33 and then swinging it left and right, the sludge is completely broken up and turned over, so as to facilitate better turning over.

[0049] It is noted that the prismatic tilling plate 37 can be swung left and right to turn the soil not only from the front side to the rear side of the sludge, but also from the rear side to the front side of the sludge.

[0050] After the soil is turned over and scattered, when the soil is dry to a preset degree, the first gear 20 and the second gear 21 in the middle are meshed, so that the prismatic turning plate 37 moves a preset length, and then the first gear 20 and the second gear 21 in the middle are meshed, so that the first gear 20 and the second gear 21 on the far left are meshed, and the prismatic turning plate 37 moves beyond the position of the sludge conveyor belt 10, so that the hard stones in it are pushed to the outside of the sludge conveyor belt 10. By moving the prismatic turning plate 37 to different positions relative to the slide plate 33, the hard stones are well screened out.

[0051] After the drying and hard stone removal are completed, the sludge conveyor belt 10 is allowed to continue conveying the preset length, and the above-mentioned actions are repeated so that new sludge is dried and hard stones are removed, thus completing the large-scale sludge drying and hard stone removal operation efficiently and automatically.
