[0019] The utility model discloses a kind of straw processing devices for straw returning to field, the straw processing device for straw returning to field mainly includes rack 1, crushing box 2, crushing mechanism 3, round hole screen 4, cover 5, discharge pipe 6, conveying auger 7, material guide pipe 8, motor 9, the crushing box 2 is installed on rack 1, crushing box 2 inside is cavity structure, crushing mechanism 3 is installed in cavity structure inside, round hole screen 4 is installed in crushing box 2 inside, located crushing mechanism 3 below, cover 5 is hinged in crushing box 2 top end, discharge pipe 6 is installed in crushing box 2 bottom end, discharge pipe 6 inside is cavity structure, conveying auger 7 is installed in discharge pipe 6 inside, material guide pipe 8 is installed in discharge pipe 6 end part, crushing box 2, discharge pipe 6, material guide pipe 8 are interconnected between, motor 9 is installed on discharge pipe 6, conveying auger 7 is transmissionally connected with motor 9.

[0020] Staff hand handle 52 open cover 5, straw is put into crushing box 2 inside, after placing, cover 5 is closed, then motor 9 and drive motor 31 are started, drive motor 31 drives pivot 32 to rotate, crushing cutter 33 installed on pivot 32 rotates, two groups of crushing cutters 33 can shear and cut the straw that is put into crushing box 2, can effectively crush straw, improve crushing efficiency, during crushing process, cover 5 can effectively reduce dust overflow generated when crushing straw, avoid staff inhaling dust, protect the health of staff, after being crushed, straw will fall on round hole screen 4 in crushing box 2, since round hole screen 4 is set as the circular arc structure that is matched with the structure of crushing cutter 33, so it can well receive the crushed straw that falls from crushing cutter 33, and the crushed straw that meets the aperture requirement of round hole screen 4 can fall into discharge pipe 6 through round hole screen 4, while larger particle straw that does not meet the requirement is left on round hole screen 4, continue to receive crushing of crushing cutter 33, ensure that the straw output from the device reaches appropriate crushing granularity, conducive to subsequent straw returning to field operation, under the drive of motor 9, conveying auger 7 installed in discharge pipe 6 inside starts to rotate, and the crushed straw that falls into discharge pipe 6 from round hole screen 4 can be conveyed along discharge pipe 6 to material guide pipe 8 direction by conveying auger 7, finally, from material guide pipe 8, complete the whole straw processing and discharging process, and straw particles are discharged from material guide pipe 8.

[0021] As Figure 4 , Figure 5As shown, the pulverizing mechanism 3 includes a drive motor 31, a rotating shaft 32, and a pulverizing cutter 33. The drive motor 31 is installed on the side wall of the pulverizing box 2, and two sets of rotating shafts 32 are rotatably installed inside the pulverizing box 2. The rotating shafts 32 are in transmission connection with the drive motor 31, and the pulverizing cutter 33 is installed on the rotating shaft 32. The drive motor 31 drives the rotating shaft 32 to rotate, and the pulverizing cutter 33 installed on the rotating shaft 32 rotates accordingly. Since there are two sets of rotating shafts 32, the two sets of pulverizing cutters 33 can shear and cut the straw put into the pulverizing box 2, thereby improving the pulverizing efficiency.

[0022] As shown in Figure 4 , Figure 5 , the round-hole screen 4 is arranged in a circular arc structure matching the structure of the pulverizing cutter 33. Since the round-hole screen 4 is arranged in a circular arc structure matching the structure of the pulverizing cutter 33, it can well receive the pulverized straw falling from the pulverizing cutter 33.

[0023] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 , the cover 5 is provided with a transparent observation window 51, and the top end of the cover 5 is provided with a handle 52. The handle 52 at the top end of the cover 5 facilitates opening and closing of the cover 5. During operation, the transparent observation window 51 on the cover 5 can facilitate the operator to observe the working condition in the pulverizing box 2.

[0024] As shown in Figure 1 , Figure 2 , Figure 3 , the pulverizing box 2 is arranged in a reverse triangular structure. The reverse triangular structure of the pulverizing box 2 is conducive to the gathering of the pulverized straw towards the round-hole screen 4 and the discharge pipe 6, making the whole process more smooth.

[0025] Working process:

[0026] The staff opens the cover 5 by holding the handle 52, puts the straw into the inside of the smashing box 2, closes the cover 5 after the placement is finished, and then starts the motor 9 and the driving motor 31. The driving motor 31 drives the rotation of the rotating shaft 32, and the smashing cutter 33 installed on the rotating shaft 32 rotates. Since there are two groups of rotating shafts 32, the two groups of smashing cutters 33 can shear and cut the straw put into the smashing box 2, so that the straw can be effectively smashed, and the smashing efficiency is improved. During the smashing process, the cover 5 can effectively reduce the dust overflow generated when the straw is smashed, avoid the staff inhaling the dust, and protect the health of the staff. The smashed straw falls on the round hole screen 4 in the smashing box 2. Since the round hole screen 4 is arranged in a circular arc structure matched with the structure of the smashing cutter 33, the smashed straw falling from the smashing cutter 33 can be well received by the round hole screen 4. The smashed straw meeting the aperture requirement of the round hole screen 4 falls into the discharge pipe 6 through the round hole screen 4, and the larger particle straw not meeting the requirement is left on the round hole screen 4 to continue to be smashed by the smashing cutter 33, so that the straw output from the device meets the appropriate smashing particle size, which is beneficial to the subsequent straw field operation. Under the driving of the motor 9, the conveying auger 7 installed in the discharge pipe 6 starts to rotate. The smashed straw falling into the discharge pipe 6 from the round hole screen 4 is conveyed by the conveying auger 7 along the discharge pipe 6 to the direction of the guide pipe 8, and finally discharged from the guide pipe 8, completing the whole process of straw treatment and discharge. The straw particles are discharged from the guide pipe 8. By smashing and returning the straw to the field, air pollution and other environmental problems caused by traditional treatment methods such as straw burning can be avoided. At the same time, the nutrient substances in the straw can be returned to the soil, which can improve the soil and increase the fertility of the soil, and meet the development requirements of modern environmental protection agriculture.

[0027] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
