DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below by combining the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0030] As Figures 1-4As shown, the agricultural fertilization tool with uniform fertilization provided by the embodiment of the present application comprises a frame 100, a fertilization hopper 400, a support plate 500, a fertilization screen 600 and a cam mechanism, wherein the frame 100 is a support structure of the fertilization tool, the bottom end of the frame 100 is symmetrically provided with bearings, the frame 100 is fixedly connected with the outer ring of the bearings, and the frame 100 is fixedly connected with an axle 200 through the inner ring of the bearings. Moreover, walking wheels 300 are fixedly arranged at the lengthwise two ends of the axle 200. The frame 100 can walk in the field or the field ridge through the walking wheels 300 arranged at the bottom end, so as to achieve the purpose of moving fertilization.

[0031] The fertilization hopper 400 is arranged at the top of the frame 100, the top of the fertilization hopper 400 is provided with an opening 420 for facilitating loading, the bottom of the fertilization hopper 400 is provided with a discharge port 410 for discharging, and the size of the opening 420 at the top is larger than the size of the bottom, so that the fertilization hopper 400 as a whole has an inverted conical structure. The design of the inverted conical structure can facilitate rapid loading, and the design of the bottom necking can accelerate the falling of the fertilizer by gravity. Specifically, the bottom of the fertilization hopper 400 can be provided with a plurality of discharge ports 410 distributed equidistantly in the circumferential direction. By arranging a plurality of uniformly distributed discharge ports 410, a ring-shaped fertilization coverage area can be formed, so as to avoid single-point concentrated spreading of the fertilizer, thereby preliminarily achieving the spatial uniform distribution of the fertilizer.

[0032] In the embodiment, the support plate 500 is a plate-shaped structure arranged above the frame 100, the surface of the support plate 500 is parallel to the horizontal plane, and the support plate 500 is provided with a notch 510 in the thickness direction, which is located in the central region of the support plate 500. The fertilization screen 600 is arranged at the notch 510 of the support plate 500, the surface of the fertilization screen 600 is parallel to the surface of the support plate 500, the length of the fertilization screen 600 is equal to the length of the notch 510, and the width of the fertilization screen 600 is smaller than the width of the notch 510, so that the fertilization screen 600 can move in the width direction of the notch 510.

[0033] In the embodiment, the outer wall of the fertilization screen 600 is provided with a frame, and the frame of the fertilization screen 600 is connected with the outer wall of the notch 510 through four groups of symmetrical spiral springs 700, that is, the frame of the fertilization screen 600 is provided with the spiral springs 700 between the frame and the outer wall of the notch 510 in the width direction. Thus, when the fertilization screen 600 moves, the spiral springs 700 will restore to the original state through the elastic force, and when the fertilization screen 600 performs periodic motion, the fertilization screen 600 will shake in the width direction of the notch 510 under the elastic force of the spiral springs 700.

[0034] The four sets of symmetrical spiral springs 700 can form bidirectional elastic constraints in the width direction of the gap 510, so as to provide vibration restoring force and limit the lateral deviation of the fertilizer screen 600. In addition, the symmetrical design can ensure the symmetry of the periodic vibration track of the fertilizer screen 600, and avoid the problem of local accumulation of fertilizer caused by the deviation of the fertilizer screen 600.

[0035] As shown in Figure 2 The cam mechanism includes an eccentric cam 800 and a wear-resistant stop plate 900. The eccentric cam 800 is fixedly arranged on the wheel shaft 200 and can rotate synchronously with the wheel shaft 200. The wear-resistant stop plate 900 is arranged on the bottom surface of the fertilizer screen 600, and the eccentric cam 800 is in contact with the bottom surface of the fertilizer screen 600 through the wear-resistant stop plate 900. When the vehicle frame 100 moves in the land or the ridge through the walking wheels 300, the eccentric cam 800 is in contact with the wear-resistant stop plate 900 on the bottom surface of the fertilizer screen 600 periodically, so as to push the fertilizer screen 600 to move in the width direction of the gap 510, and the fertilizer screen 600 performs a back and forth movement under the elastic force of the spiral spring 700.

[0036] In the agricultural fertilizer application tool provided by the embodiment of the present application, the vehicle frame 100 is provided with a support plate 500, the support plate 500 is located below the discharge port 410 at the bottom end of the fertilizer hopper 400, the support plate 500 is provided with a gap 510 in the thickness direction, the support plate 500 is connected with the fertilizer screen 600 through the gap 510, and the fertilizer screen 600 is connected with the wall surface of the gap 510 through the spiral spring 700. At the same time, the fertilizer screen 600 can move in the width direction of the support plate 500 in the gap 510. In addition, the eccentric cam 800 is fixedly connected to the wheel shaft 200 of the vehicle frame 100, the eccentric cam 800 is in contact with the bottom surface of the fertilizer screen 600, and the eccentric cam 800 can drive the fertilizer screen 600 to perform a periodic movement in the gap 510 when the eccentric cam 800 rotates. The above structure design can make the fertilizer falling from the discharge port 410 on the fertilizer screen 600 uniformly spread in the land below the fertilizer screen 600 under the vibration of the fertilizer screen 600, so as to ensure the uniformity of the fertilizer application amount, thereby preventing the crops from being affected by uneven fertilization.

[0037] In some embodiments, the bottom surface of the wear-resistant stop plate 900 is provided with a wave-shaped flange 910 in contact with the eccentric cam 800, and the wave-shaped flange 910 and the eccentric cam 800 can form multi-point alternating contact, so as to convert the rotary motion into high-frequency small-amplitude vibration, thereby improving the uniform spreading effect of the fertilizer screen 600.

[0038] In some embodiments, a linkage stirring system is further included, which comprises a driving gear 210 fixedly arranged on the wheel shaft 200 and a driven gear 220 arranged above the driving gear 210, the driven gear 220 is rotatably arranged on the side plate of the fertilizer hopper 400, and the driving gear 210 and the driven gear 220 are drivingly connected through a toothed synchronous belt 230. The driven gear 220 is fixedly connected with a transverse stirrer 240, which is arranged in the fertilizer hopper 400 and above the discharge port 410.

[0039] Through the synchronous transmission structure of the wheel shaft 200, the driving gear 210 and the driven gear 220, the walking power can be steplessly transmitted to the linkage stirring system, so that the linkage stirring system can realize the stirring function without additional power. Moreover, the stirrer 240 is arranged above the discharge port 410, which can form a dynamic arch-breaking structure in the area above the discharge port 410 to ensure that the discharge amount of each discharge port 410 remains constant, thereby ensuring the uniformity of the fertilizer from the discharge source.

[0040] Preferably, the transverse stirrer 240 is composed of a stirring shaft 241 and a plurality of stirring blades 242, the stirring blades 242 are continuously distributed in a spiral shape along the stirring shaft 241, and the continuously spiral distributed stirring blades 242 form an axial thrust when rotating, which can forcibly push the fertilizer to move to the discharge port 410, thereby avoiding the accumulation phenomenon.
