[0003] Straw contains more than half of the products of photosynthesis of crops, rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. China has a long history of using crop straw, except for a small amount of gasket, feeding livestock, part of the compost, most of them as fuel. With the development of agricultural production, the grain output has increased significantly, and the amount of straw has increased. Combined with the promotion of coal-saving and coal-saving technology, the popularity of coal and the use of liquefied gas, there is a large amount of surplus straw in rural areas. At the same time, with the progress of science and technology and the improvement of agricultural mechanization level, the use of straw is changed from composting to direct straw return to field. After the harvest is completed, the straw is crushed by a crushing machine, and then uniformly spread in the field by external equipment to realize field fertilization.

[0004] With the development of industrial technology, straw can also be reused to make feed and other products. Therefore, the crushing of straw is an indispensable part of the reuse of straw. The straw crusher is mainly used for cutting processing of crop straw, branches with a diameter of less than 5 cm and other plant straws. It can also be used for cutting processing of various crop straws and pasture. It can crush corn stalks, straw, peanut skins, bean stalks, and other combustible crop waste stalks, effectively developing renewable energy. The machine has reliable performance, simple operation and convenience.

[0028] Step four: repeat steps one to three, in step one, the crushing drive motor works to drive the crushing roller to rotate the outer arc-shaped action plate to the lower end position, the adjusting drive motor drives the rotating shaft to rotate, and through the shaft connection relationship of the first C-shaped fixed seat, the first adjusting rod, the second adjusting rod and the second C-shaped fixed seat, the first adjusting rod and the second adjusting rod are gradually elongated, and the outer arc-shaped action plate is moved outward, and the outer arc-shaped action plate takes the straw scraps clamped outside the first crushing knife and the second crushing knife away from the first crushing knife and the second crushing knife;

[0029] Step five: with the completion of straw feeding, the first crushing knife and the second crushing knife outside the straw scraps are cleaned, and the crushing is carried out again.

[0030] Compared with the prior art, the beneficial effects of the present application are:

[0031] In the application, the upper drive gear rotates, and through the meshing connection relationship of the upper drive gear and the first inclined connecting gear and the meshing connection relationship of the first inclined connecting gear and the second inclined connecting gear, the first inclined connecting gear and the second inclined connecting gear are driven to rotate outward in opposite directions synchronously, the rotating part is opened, and the limiting notch is exposed; the first bevel gear rotates, and through the meshing connection relationship of the first bevel gear and the second bevel gear, the side connecting shaft, the rotating disc and the linkage shaft are driven to rotate, the upper rotating sleeve, the connecting rod and the lower rotating sleeve are driven to move upward while rotating, the connecting rod is pulled to move upward, and the upper end of the crushing inner box extends upward through the limiting notch. The rotating drive motor drives the output shaft to rotate reversely, the crushing inner box moves downward, and the rotating part gradually closes, sealing the upper end structure. In the crushing process, the dust and debris do not float outward, but are located in the structure and will follow the next crushing process, which can prevent dust and debris from floating outward and reduce the intermediate workload, solving the problem that a large amount of debris and dust will float out during the current straw crushing process. The dust suction structure is set to suck it out. Since the target product of crushing is straw debris, the debris and dust sucked out by the dust suction structure is directly mixed into the target product. Therefore, in order to avoid dust pollution, the dust suction structure is a necessary but redundant working structure in the whole process, which is not conducive to the overall working efficiency.

[0032] In the application, the rotating driving motor drives the upper driving gear to rotate, and through the meshing connection relationship between the upper driving gear and the first bevel gear and the meshing connection relationship between the first bevel gear and the second bevel gear, the first bevel gear and the second bevel gear are driven to rotate in opposite directions. Since the upper driving gear is coaxially connected with the first bevel gear, when the rotating driving motor drives the upper driving gear to rotate, the first bevel gear rotates synchronously, and through the meshing connection relationship between the first bevel gear and the second bevel gear, the corresponding structure is driven to rotate. The driving relationship of this part is simple, only a single driving structure is introduced, the driving structure is avoided to be redundant, and the process of the exposure of the limiting notch and the upward movement of the smashing inner box is smoother, and the driving structure does not need to be driven and matched.

[0033] In the application, the smashing driving motor drives the first connecting gear to rotate, and through the meshing connection relationship between the first connecting gear and the second connecting gear, the second connecting gear is driven to rotate, and through the meshing connection relationship between the second connecting gear and the third connecting gear and the meshing connection relationship between the first connecting gear and the third connecting gear, the two smashing rollers at the lower end are driven to rotate, and the first smashing knife and the second smashing knife smash the entering straw. In this part of the smashing process, the non-driving structure is directly driven, but the gear meshing driving structure is used to rotate, and under the arrangement of the gear related structure, the rotating shaft can be driven separately in the smashing roller. The adjusting driving motor drives the rotating shaft to rotate, and through the shaft connection relationship between the first C-shaped fixing seat, the first adjusting rod, the second adjusting rod and the second C-shaped fixing seat, the first adjusting rod and the second adjusting rod are gradually elongated, the outer arc-shaped action plate is driven to move outward, the outer arc-shaped action plate takes away the straw scraps outside the first smashing knife and the second smashing knife from the first smashing knife and the second smashing knife, so that the first smashing knife and the second smashing knife do not jam the scraps, and the first smashing knife and the second smashing knife do not affect the rotation of the smashing roller or the smashing efficiency of the first smashing knife and the second smashing knife on the straw due to the jamming of the scraps outside the first smashing knife and the second smashing knife for a long time.

[0034] In the application, the first blade piece and the second blade piece are on the same smashing structure, the integrity is strong, and the structure rotates together, so that more smashing structures can be arranged in the same space, and the smashing effect on the straw can be guaranteed. The original smashing blade position is set as a sawtooth part based on the first blade piece and the second blade piece, and the sawtooth parts on the first blade piece and the second blade piece are staggered, so that the cutting length of the cutting blade is larger, and the first smashing knife and the second smashing knife are in a rotating posture when smashing the straw, a plurality of cutting blades gradually present a vertical posture with the straw, so that the cutting blade does not cut the immobile straw and drives the straw to move, the straw winding is reduced on the basis of higher smashing efficiency, the straw winding structure is arranged on the smashing roller, the smashing effect of the structure is better on the basis of reducing the intermediate cleaning and maintenance procedures, and the service life of the smashing equipment is greatly increased.

[0035] The sawtooth part outer end reinforcing plate is arranged, so that the strength of the cutting edge when cutting and crushing the straw is higher, since the straw has a reaction force on the sawtooth part, and the reinforcing plate arranged on the sawtooth part can increase the strength of the structure, avoiding the influence of the cutting effect due to the fracture of the structure for a long time of crushing and cutting.
