The blades on the large spiral shaft 12 are distributed oppositely. Taking the midpoint of the length direction of the large spiral shaft 12 as the reference, the spiral directions of the spiral blades on both sides of the midpoint are opposite. The oppositely distributed spiral blades transport the fertilizer to the hole of the rear arc plate 23 and then enter the feed channel 10. The bottom plate 18 has an oblique mouth, which is convenient for close fitting with the ground or the fertilizer feeding place, and convenient for loading.

[0026] In this embodiment, the spiral material gathering mechanism comprises a lower mounting plate 1, a small spiral shaft 2, an upper mounting plate 3, a hydraulic motor 4 and an extension plate 5. The small spiral shaft 2 is installed between the upper mounting plate 3 and the lower mounting plate 1. The lower part of the small spiral shaft 2 is connected to the lower mounting plate 1 through a bearing. The upper part of the shaft passes through the bearing and is connected to the hydraulic motor 4 through a coupling through an opening of the upper mounting plate 3.

The lower mounting plate 1 and the upper mounting plate 3 are welded to the extension plate 5. The other side of the extension plate 5 is hinged to the side plate 17. The opening size of the spiral material gathering mechanism is adjusted by the extension and contraction of the movable hydraulic cylinder 1 19 and the movable hydraulic cylinder 2 16 installed on the extension plate 5.

[0027] Furthermore, the feeder includes a belt 9, a cutter 7, a feeder knife 8 and two belt clamps 6. The two belt clamps 6 are arranged in parallel, and the two ends of the two belt clamps 6 are fixedly connected by two rollers respectively. The front roller 21 is located at the top of the shovel bucket, and the two ends of the rear roller are installed on the upper plate 22 of the shovel bucket through bearings, and the belt motor 11 is connected to the rear roller through a coupling transmission; the belt 9 is connected end to end and wrapped around the outside of the two rollers to form a transmission belt, and the outer surface of the belt 9 is cross-distributed with a cutter row and a feeder knife row at equal intervals parallel to the roller direction. The cutter row includes multiple cutters 7, and the feeder knife row includes multiple feeder knives 8.

[0028] The cutter 7 is fixed to the belt 9 by bolts. The cutter 7 is tilted, and the angle between the cutter 7 surface and the radial section of the roller is 20°; except for the feeding cutter 8 located at the center line of the belt 9, the other feeding cutters 8 are tilted, and the angle between the tilted feeding cutter 8 surface and the radial section of the roller is 80°. Taking the center line of the belt width direction of the belt 9 as the reference, there are 16 cutters 7 in each row, and the 8 cutters 7 on both sides of the center line are mirror-imaged relative to the center line. The distance between two adjacent cutters 7 in the same row is 90mm, and the spacing between two adjacent rows of cutters 7 is 200mm; Taking the center line of the belt width direction of the belt 9 as the reference, there are 16 feeding cutters 8 in each row, and the 8 feeding cutters 8 on both sides of the center line are mirror-imaged relative to the center line. The distance between two adjacent feeding cutters 8 in the same row is 90mm, and the spacing between two adjacent rows of feeding cutters 8 is 200mm. In this way, the fertilizer can be transported to the center line while the large fertilizer is chopped, which is conducive to efficient feeding. The width of the belt 9 is consistent with the distance between the two side plates 17, and the belt clamping plate 6 is outside the side plate 17 and has a hole at a corresponding position for passing the rear axle of the belt 9.

[0029] An opening adjustment hydraulic cylinder seat 20 is provided on the belt clamp plate 6, an opening adjustment hydraulic cylinder seat 2 14 is provided on the upper plate 22 of the shovel loading bucket, a cylinder body of the opening adjustment hydraulic cylinder is fixed on the opening adjustment hydraulic cylinder seat 2 14, and a telescopic rod of the opening adjustment hydraulic cylinder is fixed to the opening adjustment hydraulic cylinder seat 20. The opening adjustment of the material picker is realized by telescoping the opening adjustment hydraulic cylinder.

[0030] The feeding mechanism of the fertilizer spreader of the present invention is used to quickly scoop fertilizer placed in an irregular shape into the fertilizer spreader. The outer contour of the feeding mechanism is a shovel bucket, including an upper plate 22, a side plate 17, a lower plate 13 and a rear arc plate 23, and the internal space formed has a counter-screw. The feeder is a belt 9 equipped with a cutter 7 and a feeder 8 arranged in a certain order. The width of the belt 9 is less than the width between the two side plates 17. The front and rear shafts are used to drive the rear shaft to be installed on the side plate 17 through a bearing. The cutter 7 is arranged in a mirror image of the center line of the upper plate 22 and has a certain inclination angle with the center line, so as to realize the shredding of fertilizer and the gathering of fertilizer to the middle. The feeder 8 is arranged in a mirror image with the center line of the upper plate 22, and has a large inclination angle with the center line, so as to realize feeding to the middle of the mechanism. An extension plate 5 is hingedly connected to the side plate 17, and a mounting plate extends up and down from the front side of the extension plate 5. A spiral material gathering mechanism is installed in the middle, and the edge fertilizer is moved inward by the rotation of the spiral blade. The lower plate 13 has an oblique opening, which is upward, so that fertilizer can be shoveled in conveniently. The action of the whole mechanism is realized by the hydraulic system. The opening adjustment of the material taker and the opening size of the spiral material gathering mechanism are realized by the hydraulic cylinder, and the rotation of the auger is realized by the blade motor 15. The present invention realizes the feeding operation with high efficiency, good crushing degree and uniform feeding.

[0031] The effective example of the present invention is that no matter the fertilizer is placed in strips or piled irregularly on the ground, it can be conveniently collected. If it is placed in strips, the material extractor is not needed. It is only necessary to adjust the hydraulic cylinder according to the width of the strips so that the extension plate 5 opens a certain angle, the mechanism moves forward, and the intermediate fertilizer enters the inside of the mechanism through the bottom plate 18 with an oblique opening, and rotates through the large spiral shaft 12, and enters the feed channel 10 through the opening of the rear arc plate 23. If the fertilizer is placed irregularly, or there are large pieces of fertilizer (such as manure), the opening of the material extractor can be opened by adjusting the hydraulic cylinder, and it can be contacted with the upper part of the fertilizer pile, and then the belt motor 11 works, the belt 9 rotates, the cutter 7 and the material extractor 8 move, the cutter 7 cuts the large piece of fertilizer into pieces and moves it to the center line position, and the material extractor 8 further moves the fertilizer to the center line position. The combined action of the two cuts the fertilizer into pieces and distributes the fertilizer in strips in front of the bottom plate 18. The spiral gathering mechanisms on both sides can also be selected to work according to actual conditions, making it more convenient for fertilizer to enter.

[0032] The present invention realizes the feeding of fertilizers in strip shape or irregular distribution or with large fertilizer lumps, and during the working process, uniform chopping before feeding is achieved, no fertilizer is left on both sides, feeding is more uniform, labor intensity is reduced, labor demand is reduced, and the use of organic fertilizers and industrial development are promoted.
