Description

Technical Field

[0001] This utility model relates to the field of fertilizer application equipment technology, and in particular to a mobile fertilizer applicator. Background Technology

[0002] As is generally known, corn-soybean strip intercropping technology refers to a planting pattern in which corn and soybeans are intercropped or relay-cropped under the premise of ensuring that the light requirements of the two crops are not mutually blocked. During the middle of its growth, corn needs to be top-fertilized. At this time, the corn plants are usually 1.2-1.6 meters tall, and large fertilizer machinery cannot enter the row to work. It is necessary to rely on manpower or small special machinery to complete the work.

[0003] Chinese patent CN222396130U describes a corn-soybean strip intercropping fertilization device, which includes a connecting frame and ground wheels. The connecting frame houses a seed planter and a fertilizer applicator, each with a quantity adjustment device. However, in actual use, the following problems exist:

[0004] During the topdressing period, soil compaction is prone to occur, forming a large number of hard clumps in the soil, resulting in uneven soil hardness. Existing small fertilizer applicators are unable to effectively break up the compacted layer and hard clumps between rows, leading to uneven mixing of fertilizer and soil and reduced fertilizer utilization. At the same time, the fertilization depth is unstable due to the influence of topographic undulations and varying soil hardness. If it is too shallow, fertilizer will volatilize and be lost; if it is too deep, crops will have difficulty absorbing it, which seriously affects the fertilization effect.

[0005] Therefore, a mobile fertilizer applicator is proposed. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a mobile fertilizer applicator.

The movable end of the adaptive angle component is connected to the fixing rod 8.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the adaptive angle assembly includes a connecting rod 9 and an elastic telescopic support column 10. The top end of the connecting rod 9 is hinged to the lower surface of the bearing frame 2 via a pin, and the bottom end of the connecting rod 9 is fixedly connected to the fixed rod 8. One end of the elastic telescopic support column 10 is hinged to the side of the connecting rod 9 away from the drive wheel 1 via a pin, and the other end of the elastic telescopic support column 10 is hinged to the lower surface of the bearing frame 2 via a pin.

[0028] like Figure 1-4 As shown, there are two depth-fixing components, which are symmetrically distributed on both sides of the hollow plowshare 6. The depth-fixing components include a fixed horizontal plate 11, a fixed vertical plate 12, an elastic telescopic column 13, and a depth-fixing wheel 14. One end of the fixed horizontal plate 11 is fixedly connected to the outer wall of the hollow plowshare 6. The top end of the fixed vertical plate 12 is fixedly connected to the lower surface of the fixed horizontal plate 11. The bottom end of the fixed vertical plate 12 is rotatably connected to the depth-fixing wheel 14 through an axle. The bottom end of the elastic telescopic column 13 is fixedly connected to the upper surface of the fixed horizontal plate 11. The top end of the elastic telescopic column 13 is fixedly connected to the lower surface of the support frame 2.

[0029] like Figure 1-4 As shown, each of the two fixed longitudinal plates 12 is provided with a soil covering plate 15. One end of the soil covering plate 15 is fixedly connected to the side of the fixed longitudinal plate 12. The two soil covering plates 15 are in a "V" shape, and the closed end of the "V" shape of the two soil covering plates 15 faces the driven wheel 3.

[0030] like Figure 4 and Figure 6 As shown, the outer wall of the discharge pipe 5 is provided with an axial groove 16, and a limiting slider 17 is provided in the axial groove 16. One end of the limiting slider 17 is fixedly connected to the inner wall of the hollow plow head 6, and the other end of the limiting slider 17 is located in the axial groove 16 and is slidably connected to the inner wall of the axial groove 16.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the cutting disc 7 is provided with a plurality of extrusion blocks 18, which are evenly distributed circumferentially along the axis of the cutting disc 7, and the extrusion blocks 18 are fixedly connected to the side of the cutting disc 7.

[0032] The work process is as follows:

[0033] S1, during use, start the drive wheel 1, and the user holds the handle of the support frame 2 to push the device forward. The loosening cutter head, located between the drive wheel 1 and the hollow plow head 6, first contacts the soil. The loosening cutter head consists of two "V"-shaped cutting discs 7 and a fixing rod 8. Under the pre-tension of the elastic telescopic support column 10, it is pushed by the connecting rod 9 to loosen the soil. When encountering hardened clods, the resistance increases sharply, pushing the fixing rod 8 and forcing the connecting rod 9 to swing backward and upward around its top hinge point, overcoming the elastic force of the elastic telescopic support column 10, so that... The cutting angles of the two cutting discs 7 become smaller and sharper, thus efficiently breaking up hard soil clods. During this process, several extrusion blocks 18, evenly distributed around the axis of the cutting discs 7, assist in breaking up the soil clods. Through the synergistic action of the cutting discs 7, the fixed rod 8, the connecting rod 9, and the elastic telescopic support column 10, the cutting angles of the two cutting discs 7 change with the soil hardness, avoiding incomplete loosening of the soil when the fertilizer applicator encounters compacted soil, which would cause the fertilizer to be applied to the hard soil surface and fail to mix effectively with the soil, resulting in reduced fertilizer application efficiency and improved fertilization efficiency.

[0034] S2, during fertilization, the fertilizer discharge assembly 4 is activated. The hollow plowshare 6, located behind the loosening cutter head, is inserted into the loosened soil treated by the loosening cutter head. Fertilizer is introduced into the hollow plowshare 6 through the discharge pipe 5 and then falls into the soil. At this time, two fixed-depth wheels 14, symmetrically distributed on both sides of the hollow plowshare 6, roll on the uncultivated land. The fixed longitudinal plate 12 and fixed transverse plate 11 set a stable furrowing depth benchmark for the hollow plowshare 6. The elastic telescopic column 13 continuously provides downward pressure to ensure the insertion depth of the hollow plowshare 6. When the terrain undulation causes the bearing frame 2 to move up and down, the hollow plowshare 6 is fixed by its inner wall. The limiting slider 17 slides with the axial groove 16 on the outer wall of the discharge pipe 5 to stabilize the insertion depth of the hollow plow head 6. After fertilization, the two "V"-shaped soil covering plates 15 fixed on the fixed longitudinal plate 12 naturally backfill and cover the soil on both sides of the ditch, completing the entire fertilization operation. Through the cooperation of the fixed depth wheel 14, the fixed longitudinal plate 12, the fixed transverse plate 11 and the elastic telescopic column 13, the insertion depth of the hollow plow head 6 is stabilized, avoiding the fertilizer volatilization due to undulating terrain and different soil hardness, or the crop being unable to absorb the fertilizer due to excessive depth, thus improving the stability of the fertilization depth and the efficiency of fertilizer use.
