[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] A biochar spreading device for restoring degraded grasslands on the Qinghai-Tibet Plateau, such as Figures 1 to 4 As shown, it includes a base 1, the bottom end of the base 1 is provided with multiple sets of supporting wheels, and the top end of the base 1 is fixedly connected to an ash spreading mechanism 2;

[0027] The ash scattering mechanism 2 comprises a box body 201 fixedly connected to the top end of the base 1, a plurality of blow pipes 202 fixedly connected to the top end of the box body 201, a plurality of suction pipes 203 arranged in the box body 201 and respectively communicated with the interiors of the blow pipes 202, the bottom end of each suction pipe 203 being close to the bottom end of the inner wall of the box body 201, a wind deflector 204 communicated with one end of the plurality of blow pipes 202, a plurality of fans 205 fixedly connected to the inner wall of the wind deflector 204, a water tank 4 fixedly connected between the bottom end of the box body 201 and the base 1, a water pump 5 fixedly connected to the top end of the box body 201, the input end of the water pump 5 being communicated with the bottom end of the water tank 4 through a group of pipelines, and a spray head 6 fixedly connected to the top end of the wind deflector 204 and communicated with the output end of the water pump 5 through another group of pipelines.

[0028] The fans 205 blow air, so that the air is blown out from the interiors of the blow pipes 202. In the process of passing through the blow pipes 202, the air in the interiors of the blow pipes 202 flows at a high speed, so that a negative pressure is generated in the interiors of the blow pipes 202, thereby sucking the powdered biochar in the box body 201 into the interiors of the blow pipes 202 through the suction pipes 203. Then the biochar is blown out along with the air, and the water in the water tank 4 is pumped into the interior of the spray head 6 through the water pump 5, so that the water is sprayed out, thereby mixing the biochar with the water and avoiding dust raising.

[0029] Please refer to Figure 3 and Figure 4 , the side wall of the base 1 is fixedly connected with a connecting mechanism 3, the connecting mechanism 3 comprises two groups of guide rods 301, the outer walls of the two groups of guide rods 301 are slidingly sleeved with sliding blocks 302, the side wall of the base 1 is fixedly connected with a limiting plate 305, the side wall of each sliding block 302 is fixedly connected with a connecting rod 306, the end of the connecting rod 306 is provided with a fixing hole 307, the inner wall of each sliding block 302 is slidingly connected with a limiting pin 303, one end of the limiting pin 303 extends to the outside of the sliding block 302, the end of the limiting pin 303 is matched with a groove on the limiting plate 305, the side wall of the limiting pin 303 is fixedly connected with a return spring 304, and the end of the return spring 304 is fixedly connected to the inside of the sliding block 302.

[0030] The fixing hole 307 is sleeved on the towing hook at the tail of the tractor, and the device is pulled forward by the power of the tractor. Before the fixing hole 307 is sleeved on the towing hook, the limiting pin 303 is pushed to compress the return spring 304, so that the limiting pin 303 slides out of the groove on the limiting plate 305, and then the sliding block 302 is pushed to slide on the outer wall of the guide rod 301, so as to change the height of the fixing hole 307. When the height of the fixing hole 307 is adjusted to the appropriate position, the limiting pin 303 is released, so that the return spring 304 rebounds to push the limiting pin 303 to slide into the groove on the limiting plate 305, so that the sliding block 302 cannot slide on the outer wall of the guide rod 301.

[0031] In use, the biochar is blown by airflow and arranged in a fan shape between the multiple groups of blow pipes 202, so that the spreading area is increased, and water is sprayed from the spray head 6 by the water pump 5 during the spreading process, so that the powdered biochar is mixed with water, dust is avoided, and the grassland is supplemented with water, and the parts not involved in the device are the same as the prior art or can be realized by using the prior art.

[0032] Although the embodiments of the utility model have been shown and described, the specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and the person skilled in the art can make modifications, replacements and changes without creative contribution after reading the specification without departing from the principles and the purpose of the utility model, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
