An installation groove 7 is opened at the front end of the fine crushing barrel 5. A filtering component 8 is installed in the middle of the installation groove 7;

[0031] The filtering component 8 includes a filter plate 801, a filter element hole 802 and a handle 803. The filter plate 801 is installed in the middle of the installation groove 7. The filter element hole 802 is opened in the middle of the filter plate 801. The handle 803 is arranged on the outer surface of the filter plate 801;

[0032] A rotary motor 9 is provided at the rear end of the fine crushing barrel 5; a second stirring blade 10 is installed at the driving end of the rotary motor 9, a cleaning component 11 is installed at the right front end of the fine crushing barrel 5, and a collection box 12 is arranged for the fine crushing barrel 5. Specifically, first of all, the utility model can automatically perform secondary crushing treatment on multi-stage straw. First, the multi-stage straw is placed in the middle of the frame 1. By starting the motor 2 to drive the first stirring blade 3, the multi-stage straw can be pretreated and crushed. The crushed multi-stage straw directly falls into the discharge port 4, reaches the fine crushing barrel 5 through the receiving groove 6, and is automatically discharged. The straw falling into the fine crushing barrel 5 is crushed again by the second stirring blade 10 inside the fine crushing barrel 5, greatly improving the straw crushing effect and strengthening the straw crushing force. An installation groove 7 is provided at the bottom of the front end of the fine crushing barrel 5, which is convenient for placing the filtering component 8 in the installation groove 7. Hold the handle 803 and place the filter holes 802 of the filter plate 801 at the bottom discharge port of the fine crushing barrel 5. By starting the rotary motor 9, the second stirring blade 10 is driven to continuously crush the straw. The crushed qualified straw will automatically fall into the collection box 12 through the filter holes 802 of the filter plate 801 for collection. The straw with unqualified crushing fineness will be continuously filtered on the filter plate 801 for re-crushing treatment, avoiding problems such as uneven crushing of the multi-stage straw in the fine crushing barrel 5, resulting in poor crushing quality after returning to the field, most not meeting the fine crushing requirements, causing the soil to be loose, wasting water for irrigation, and affecting the nutrients required for seedling growth. Users can replace the filter holes 802 of the filter plate 801 according to the straw crushing requirements, and can replace them with finer filter holes 802 to reduce the situation of unqualified straw falling. The directly qualified finely crushed straw can fall through the fine filter holes 802, greatly improving the crushing of different straw fineness. The used filter holes 802 can be cleaned by the cleaning component 11. The track 1101 is located on both sides of the fine crushing barrel 5.

Through this technical solution, the problem that after the multi-stage straw returns to the field after the fine crushing device, if the crushing quality is poor, most do not meet the fine crushing requirements, resulting in loose soil, wasting water for irrigation, and affecting the nutrients required for seedling growth is solved, thereby reducing the problem of the straw crushing effect of the fine crushing device. It realizes that an installation groove 7 is provided at the bottom of the front end of the fine crushing barrel 5, which is convenient for placing the filtering component 8 in the installation groove 7. Hold the handle 803 and place the filter holes 802 of the filter plate 801 at the bottom discharge port of the fine crushing barrel 5. By starting the rotary motor 9, the second stirring blade 10 is driven to continuously crush the straw. The crushed qualified straw will automatically fall into the collection box 12 through the filter holes 802 of the filter plate 801 for collection,The straw with unqualified crushing fineness will be continuously filtered on the filter plate 801 for re-crushing to avoid problems such as uneven crushing of the straw inside the fine crushing barrel 5, resulting in poor crushing quality after multi-stage straw returning to the field, most of which do not meet the requirements of fine crushing, causing the soil to be loose, wasting water for irrigation, and affecting the nutrients required for the growth of seedlings.

[0033] Furthermore, as Figure 1-2 shown: It also includes a placement and collection box 12 for the fine crushing barrel 5. The advantage of this technical solution is that the user can replace the filter element holes 802 of the filter plate 801 according to the requirements of straw crushing, and can replace them with smaller filter element holes 802 to reduce the situation of unqualified straw falling. The directly qualified crushed straw can fall from the small filter element holes 802, greatly improving the crushing of different straw fineness.

[0034] In the above solution, there is also a problem that it is not convenient to clean the filter element holes 802. As Figure 1 、 Figure 3 and Figure 4 shown: In this solution, the cleaning component 11 includes a track 1101, a slider 1102, an electric telescopic rod 1103, and a cleaning brush 1104. Tracks 1101 are arranged on both sides of the fine crushing barrel 5, and a slider 1102 is installed in the middle of the track 1101. An electric telescopic rod 1103 is installed at the inner wall end of the slider 1102, and a cleaning brush 1104 is arranged at the output end of the electric telescopic rod 1103. The filter element holes 802 can be cleaned by the cleaning component 11. The tracks 1101 are located on both sides of the fine crushing barrel 5. The slider 1102 moves in a circular motion within the track 1101, and the cleaning brush 1104 at the driving end of the electric telescopic rod 1103 is used to clean the aperture of the filter element holes 802, greatly improving the cleanliness of the filter element holes 802 and avoiding the situation of blockage when the filter element holes 802 are in use.
