[0020] Now, the present utility model will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Please refer to Figures 1-5 , an earthwork turning, sunning and drying device, including an upper frame body 1 and a lower frame body 2. Extension plates 3 extending towards each other are provided on both sides of the upper frame body 1 and the lower frame body 2. The two extension plates 3 on the same side are hinged to each other. The angle of the upper frame body 1 can be adjusted and swung back and forth. A plurality of drying cylinders 12 are provided in the upper frame body 1, and the ports of the drying cylinders 12 are vertically downward. A crushing mechanism is provided in the lower frame body 2, and the crushing mechanism is arranged directly below the drying cylinders 12. A plurality of sunning plows 62 are provided on one side of the lower frame body 2, and a towing frame 21 is provided on one side of the lower frame body 2 where the sunning plows 62 are located. The towing frame 21 is connected to an external tractor.

[0022] During the use process, the tractor is in a driving state. When driving, the sunning plows 62 first turn over the earthwork, and the turned-over earthwork is then crushed to loosen the soil mass for drying and sunning; since the drying cylinders 12 are arranged directly above the crushing mechanism, the hot air in the drying cylinders 12 will blow towards the loosened soil mass, which can accelerate the drying and sunning of the earthwork.

[0023] Since the drying cylinders 12 are arranged in the upper frame body 1, and the upper frame body 1 is hinged to the lower frame body 2 through the extension plates 3, the upper frame body 1 can swing back and forth; when the upper frame body 1 swings back and forth, the drying cylinders 12 will also swing accordingly, so that the hot air blows back and forth towards the soft soil mass, improving the drying and sunning efficiency.

[0024] In the solution of the present utility model, hinge plates 7 are provided on the opposite sides of the upper frame body 1 and the lower frame body 2. The hinge plates can swing back and forth on the upper and lower frame bodies, and the swinging direction is the same as that of the upper frame body. A cylinder 8 is provided on the lower hinge plate 7, and the end of the piston rod of the cylinder 8 is connected to the upper hinge plate 7. The upper frame body 1 can swing reciprocally through the cylinder 8 and the hinge plate 7.

[0025] Due to the establishment of the upper and lower hinge plates 7, when the piston rod of the cylinder 8 extends, the upper frame body 1 will tilt towards the direction of the turning plow 62. At this time, the drying cylinder 12 will blow hot air towards the other side; similarly, when the cylinder 8 contracts, the upper frame body 1 will return to the horizontal and tilt towards the cylinder direction. At this time, the drying cylinder 12 will blow hot air towards the turning plow direction. In this way, the drying efficiency can be increased by reciprocating; the soil mass dried by hot air still carries some moisture and can be dried by sunning.

[0026] Specifically, a fixed cover 4 is provided in the lower frame body 1 along its own length direction. The crushing mechanism is arranged in the fixed cover 4. The crushing mechanism includes a rotating roller 41. A plurality of rake teeth are arranged on the circumference of the rotating roller 41. One end of the rotating roller 41 extends outwards to be provided with a driven belt pulley 42. A driving belt pulley 51 is provided on the outer side of the extension plate 3. A motor 5 is provided on the other side of the extension plate 3. The motor 5 is in transmission connection with the driving belt pulley 51. The driving belt pulley 51 and the driven belt pulley 42 are in transmission connection through a belt; therefore, when the motor 5 is started, the rotating roller 41 is driven to rotate through the driving belt pulley 51, the belt and the driven belt pulley 42. When the driving roller 41 rotates, the surrounding rake teeth will turn over and sun the soil mass again, and at the same time can crush it, keeping the soil mass soft and accelerating the evaporation of moisture.

[0027] The turning plow 62 is fixed at the bottom end of the lifting rod 61. The lifting rod 61 is arranged in the fixed cylinder 6. The fixed cylinder 6 is fixed on the outer side of the lower frame body 2. The tops of a plurality of the lifting rods 61 are provided with an integrated cross plate 63. The height of the lifting rod 61 and the turning plow 62 is adjusted up and down through the cross plate 63.

[0028] When the cross plate 63 is lifted upwards, the lifting rod 61 and the turning plow 62 also rise accordingly. At this time, the turning depth of the turning plow 62 decreases; when the cross plate 63 descends, the lifting rod 61 and the turning plow 62 descend accordingly. At this time, the turning depth of the turning plow 62 increases; the overall turning depth is adjustable.

[0029] In order to facilitate the adjustment of the height of the cross plate 63, a second connecting plate 65 is provided between two adjacent fixed cylinders 6. A screw rod 66 is vertically fixed between the second connecting plate 65 and the cross plate 63. An adjusting sleeve 67 is arranged around the screw rod 66. The adjusting sleeve 67 can abut against the cross plate 63 upwards.

[0030] Among them, the adjusting sleeve 67 is fitted with the screw rod 66 through threads. That is to say, the adjusting sleeve 67 abuts against (lifts) the cross plate 63 through threads, so as to realize the lifting of the cross plate.

[0031] After the position of the lifting rod 61 is determined, in order to ensure that it no longer lifts or lowers, connection holes 64 are provided on the outermost fixed cylinders 6 on both sides. Locking screw rods are arranged in the connection holes 64. The locking screw rods are tightened against the outer wall of the lifting rod 61. After being tightened, the lifting rod 61 cannot lift or lower, which can ensure stable sunning.

[0032] In this embodiment, a plurality of the drying cylinders 12 are separated by a first connecting plate 11. A filter screen is provided at the port of the drying cylinder 12 to prevent foreign objects from entering the cylinder. An induced draft fan is provided below the filter screen. The air outlet of the drying cylinder 12 is conical, and a spiral electric heating wire is provided on the inner wall of the conical air outlet. When in use, air enters the drying cylinder 12 from the filter screen through the induced draft fan. When discharging, the air passes through the electric heating wire, and the air is heated by the electric heating wire, so that high-temperature hot air is blown out to dry the soil mass.

[0033] The using method of the utility model comprises the following steps: S1: The lower frame body is connected to an external tractor through a traction frame; S2: Adjust the extending length of the lifting rod; S3: Start the tractor, the motor and the drying cylinder, and drive the tractor to the soil area; S4: Lower the lower frame body through the tractor, and then the tractor travels; S5: After traveling, the sunning plow first suns the soil mass, then loosens it through the harrow teeth, and at the same time dries and suns it through the hot air blown out by the drying cylinder.

[0034] In addition, large-area soil masses are jointly operated by mechanized construction equipment such as bulldozers and excavators. After sunning, the contact area between the soil material and the air is increased, thereby improving the efficiency of reducing the moisture content. First, use an excavator and a bulldozer to level the site, and then use a sunning plow to deeply plow to a depth of not less than 30 cm.

[0035] When in use, use a harrow tooth crusher to turn and mix back and forth 4 times every 2-4 days (when turning and mixing each time, be sure to turn to the bottom layer of soil), and turn on the drying cylinder to dry, accelerating the evaporation of moisture in the soil mass. After turning and mixing, air-dry and sun-dry again to further reduce the moisture content in the soil mass, and at the same time measure its moisture content every day. If it rains, cover the soil sample with a plastic film.

[0036] The number of sunning and drying times is determined according to the difference between the natural moisture content and the optimum moisture content of the soil material and the weather conditions at that time. During the sunning and drying process, the moisture content of the soil material is detected at any time. When the moisture content of the soil material is close to the optimum moisture content (between the optimum moisture content -2% and +3%), the sunning and drying times can be stopped.

[0037] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of this utility model.
