The present application relates to a kind of liquid fertilizer injection device suitable for fertilizing tank truck, belong to agricultural machinery field, including a fertilizer pipeline, the rear end of the fertilizer pipeline is provided with fertilizing tank truck interface, front end is provided with spray head;Wherein, organic liquid fertilizer is stored in fertilizing tank truck, fertilizing tank truck interface is used to with fertilizing tank truck and receives the organic liquid fertilizer in the fertilizing tank truck, spray head is used to the organic liquid fertilizer in fertilizer pipeline is injected outward;Rotary mechanism is provided on the fertilizer pipeline, rotary mechanism can make spray head relative to the rotary motion of the rear end of fertilizer pipeline, for realizing the organic liquid fertilizer is injected outward in the form of rotation;Fertilizer pipeline is also provided with pitch adjusting mechanism, pitch adjusting mechanism can make the spray head upward or downward, for realizing the organic liquid fertilizer is injected outward at the angle of elevation or depression angle.

The invention discloses a mechanical packaging full-chain desertification-free treatment system for a plum-leaf crab seed refrigeration house, which relates to the field of fruit and vegetable seed postpartum treatment complete equipment and comprises a refrigeration house low-temperature after-ripening module, a protective crushing and siphon separation module, a humidity gradient packaging and freezer storage module, a quality online detection module and a central control module. The protective crushing and siphon separation module is used for crushing and separating the plum-leaf crab seeds, and the humidity gradient packaging and freezer storage module is used for packaging and storing the treated plum-leaf crab seeds. Through the arrangement mode of the quality on-line detection module, sand grains and impurities on the surfaces of the seeds are thoroughly checked through exclusive detection, so that the integrity and size uniformity of the seeds can be monitored in time after mechanical treatment, treatment parameters can be adjusted according to conditions, the seeds are prevented from being damaged or sand grains are prevented from being embedded, and the quality of the seeds is improved. Furthermore, the online desertification-free detection operation on the quality of the plum-leaf crab seeds is facilitated.

The utility model discloses a river shoal side slope structure for preventing water and soil loss, which comprises a side slope, a plurality of buffer reinforcing members arranged in the side slope, a plurality of buffer reinforcing members horizontally connected through transverse connecting rods and vertically connected through longitudinal connecting rods; the plant root protection boxes are connected to the transverse connecting rods, plants are planted in the plant root protection boxes, and the upper plant root protection box and the lower plant root protection box are connected through a reinforcing connecting plate. According to the utility model, the plurality of buffer reinforcing members are arranged in the side slope, and the plurality of buffer reinforcing members are transversely connected through the transverse connecting rods, longitudinally connected through the longitudinal connecting rods and connected front and back through the reinforcing rods, so that the plurality of buffer reinforcing members form a point net shape, and the points are triangular connecting boxes; the plant root protection boxes are connected to the transverse connecting rods, so that the plants and the buffer reinforcing pieces form a complete ecological structure, and when a rainstorm occurs, the structure is high in flood-fighting capacity, and water and soil loss is avoided.
