Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a fertilizing device used for agricultural planting. Background Art

[0002] Fertilization refers to the agricultural technical measure of applying fertilizers to the soil or spraying them on plants to provide nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, improve soil fertility and increase economic benefits.

[0003] Fertilization includes soil fertilization, stem and leaf fertilization, and irrigation fertilization. Soil fertilization usually involves applying fertilizer to the soil and absorbing it through the roots. Before sowing or planting, the fertilizer needs to be spread on the ground, and then deep plowed to turn the fertilizer into the soil as a base fertilizer. Stem and leaf fertilization usually involves preparing a solution of fertilizer and spraying it on the stems and leaves of crops, relying on the leaves and branches to absorb nutrients. Irrigation fertilization is generally used for topdressing, which involves dissolving the fertilizer in water and applying it to the soil along with the water.

[0004] When fertilizing the soil, especially deep fertilization, it is necessary to manually groove the soil and then put the fertilizer in. After the fertilization is completed, the loosened soil after the groove is covered with fertilizer to increase the soil fertility and keep the effective ingredients in the fertilizer from being lost less. At present, there are also some fertilization devices that can complete automatic fertilization operations. Operators use fertilization devices to complete grooves and fertilization between fields, but there are still some problems: first, in different areas or under different soil conditions, the distances between the spaced grooves are different. When the distance is too close, the soil fertility is too high, which will cause the roots to not absorb water and fertilizer normally, resulting in seedling burning. When the distance is too far, the soil fertility in the middle interval area is low, affecting planting. The existing fertilization device cannot control the groove interval well, and the fertilization depth is different under different soil conditions. The current fertilization device cannot control the fertilization depth according to the soil conditions; second, after the fertilization is completed, the current fertilization device needs to manually cover the turned-up soil back to the original position, resulting in the low efficiency of the entire fertilization process and a large workload for the operator.

[0005] Therefore, we propose a fertilizing device for agricultural planting to solve the above-mentioned problems.

[0006] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

[0043] See also Figure 1-Figure 4 , a fertilization device for agricultural planting, comprising: a mobile frame 1, a fertilizer storage tank 2, and a fertilization component 3;

[0044] The mobile frame 1 includes a support 101 with running wheels, a push rod 102 and a support plate 103, wherein the push rod 102 is installed on the side of the support 101, and the support plate 103 is installed in the middle of the bottom surface of the support 101;

[0045] The fertilizer storage tank 2 includes a tank body 201 and a feed pipe 202. The tank body 201 is fixed on the bracket 101, and the feed pipe 202 is connected to the tank body 201.

[0046] The fertilization assembly 3 includes a position adjustment mechanism 301, a depth adjustment mechanism 302, a slotted plate 303 and a covering plate. The position adjustment mechanism 301 includes a motor 3011 and a lead screw 3012 fixed to the output shaft of the motor 3011. The motor 3011 is fixed to the support plate 103. The lead screw 3012 is rotatably connected to the bracket 101. Two groups of movable blocks 3013 are threadedly sleeved on the lead screw 3012. The two groups of movable blocks 3013 are fixed to each other. Both ends of the two groups of movable blocks 3013 are rotatably connected to a rotating rod 3014. The rotating rod 3014 is provided with a positioning groove 3015. The bottom surface of the bracket 101 is also provided with four positioning columns 3016. The positioning columns 3 016 is located in the positioning groove 3015 and is engaged with the rotating rod 3014. When the device is placed on the land and fertilizer is applied on both sides, the relative distance between the slotted plates 303 on both sides can be adjusted according to the width of the interval. At the same time, the angle of the slotted plates 303 can be kept consistent with the direction in which the slotting is required during slotting, and when the interval width of the slotted plates 303 is adjusted, its angle will not change, thereby avoiding changes in the size and angle of the slots on the left and right sides during slotting. The depth adjustment mechanism 302 is provided with two groups, each group includes an outer shell 3021, and the outer shell 3021 is rotatably connected to the ends of the two rotating rods 3014 on the same side. An electric push rod 3022 is provided in the outer shell 3021, and a push plate 3023 is provided at the output end of the electric push rod 3022. The bottom end of the push plate 3023 is fixed to the slotted plate 303 and the covering plate 304. A first guide rod 3024 is also provided in the outer shell 3021, and a second guide rod 3025 is also provided on the top surface of the push plate 3023. The first guide rod 3024 is movably sleeved in the second guide rod 3025. A spring 3026 is also provided on the surface of the first guide rod 3024. The two ends of the spring 3026 are respectively fixed to the second guide rod 3025 and the outer shell 3021. The depth of the slotting is different according to different soil conditions. When deep application is required or the soil is hard, , control the depth adjustment mechanism 302 to press the slotted plate 303 deeper into the soil, so as to slot and release the fertilizer. When deep application is not required, the slotted plate 303 can be made to touch the ground for fertilization. The slotted plate 303 and the covering plate 304 are both "V"-shaped, and the height of the bottom surface of the slotted plate 303 from the ground is lower than the bottom surface of the covering plate 304, and the width of the covering plate 304 is greater than the slotted plate 303, so that after the slotted plate 303 is slotted, the covering plate 304 will only cover the soil squeezed out of the slotted plate 303 back to the original position when covering the soil, and cover the fertilizer; the middle part of the covering plate 304 is also provided with an arc surface, and the bottom end of the feed pipe 202 extends into the slotted plate 303.

[0047] The working principle of this embodiment is as follows: the operator holds the push rod 102 to move the entire device into the soil, adjusts the spacing between the slotted plates 303 on the left and right sides according to the required slotting interval width, and starts the control motor 3011. The rotation of the lead screw 3012 drives the movable block 3013 to move to one side. Under the action of the positioning column 3016, the rotating rod 3014 drives the depth adjustment mechanism 302 to move to a suitable position. Thereafter, the electric push rod 3022 is started, so that the slotted plate 303 is pressed into the soil, and the bottom surface of the covering plate 304 contacts the surface of the soil. The operator pushes the entire device to move, and the slotted plate 303 is slotted. At the same time, the fertilizer is evenly scattered in the groove from the tank body 201 through the feeding pipe. When the covering plate 304 passes by, the turned soil is pushed back to the original position and covered on the fertilizer. After the operation is completed, the motor 3011 is started, and under the drive of the rotating rod 3014, the entire fertilization assembly 3 is collected under the bracket 101.
