Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an embodiment of a quantitative fertilization device: such as... Figures 1 to 3 As shown, it includes a shovel handle 1, with a grip 3 at the upper end and a shovel head 2 at the lower end. A fertilizer application channel 201 is provided on the shovel head 2. The shovel handle 1 is cylindrical and has a sliding rod 10 inside. A pull rod 11 and an insertion rod 13 are provided at the upper and lower parts of the sliding rod 10, respectively. A storage box 4 is provided outside the shovel handle 1. A metering cylinder assembly 5 is provided at the lower part of the storage box 4 and communicates with it. A switch assembly 8 connected to the sliding rod 10 is provided between the storage box 4 and the metering cylinder assembly 5. A connecting pipe assembly 6 connected to the interior of the shovel handle 1 is provided at the lower part of the metering cylinder assembly 5.

[0028] When fertilizing, first pour an appropriate amount of granular fertilizer into the storage box 4. During this process, the fertilizer will enter the metering cylinder assembly 5 and the connecting pipe assembly 6. At this time, the lower part of the sliding rod 10 just blocks the connection between the connecting pipe assembly 6 and the shovel handle 1, thereby temporarily storing the fertilizer granules in the metering cylinder assembly 5 and the connecting pipe assembly 6.

[0029] The user then holds the fertilizer applicator by the handle 3 and inserts the shovel head 2 at a certain angle into the soil where fertilizer is needed. Using the lower end of the shovel head 2 as a fulcrum, the user pushes the handle 1 towards the storage bin 4, causing the fertilizer applicator to rotate at a certain angle and excavate the fertilizer pit. The user then pulls the lever 11 upwards with their fingers, causing the sliding rod 10 to slide upwards, thus moving the lower part of the sliding rod 10 away from the connection between the connecting pipe assembly 6 and the handle 1. At this point, the previously temporarily stored feed cylinder assembly 5 and the connecting pipe assembly 6... The fertilizer granules inside can enter the shovel handle 1 and finally fall into the excavated fertilizer pit through the fertilizer channel 201. At the same time, the sliding rod 10 can drive the switch assembly 8 to cut off the connection between the storage box 4 and the metering cylinder assembly 5, so as to prevent the fertilizer in the storage box 4 from continuously entering the metering cylinder assembly 5 and the connecting pipe assembly 6 during the process of falling into the fertilizer pit. Only the fertilizer that has fallen into the metering cylinder assembly 5 and the connecting pipe assembly 6 beforehand will fall into the fertilizer pit, thereby achieving the purpose of quantitative fertilization.

[0030] As the sliding rod 10 is pulled upward by the pull rod 11, the insertion rod 13 will also move upward simultaneously. After fertilization is completed, the pull rod 11 is released. At this time, the sliding rod 10 slides down under the action of gravity, and at the same time, it will drive the insertion rod 13 downward back into the fertilization channel 201, thereby assisting the fertilizer to pass through the fertilization channel 201. Even if the fertilizer that has become damp and clumped accidentally blocks the fertilization channel 201, the falling insertion rod 13 can flush the blockage down the line, achieving the purpose of automatically clearing the blockage.

[0031] After the sliding rod 10 falls back to its original position, it seals the connecting pipe assembly 6 and the shovel handle 1 again. The switch assembly 8 also reconnects the storage box 4 and the metering cylinder assembly 5. At this time, the fertilizer in the storage box 4 will enter the metering cylinder assembly 5 and the connecting pipe assembly 6 to measure the fertilizer for the next application.

[0032] like Figure 3 As shown, a first elastic element 12 is provided between the sliding rod 10 and the shovel handle 1. The first elastic element 12 is a spring. When the sliding rod 10 is pulled upward by the pull rod 11, the first elastic element 12 will also be compressed, thereby storing force in the first elastic element 12. After the fertilization is completed and the pull rod 11 is released, the rebound force of the first elastic element 12 will also push the sliding rod 10 down, thereby assisting the sliding rod 10 to reset and increasing the force of the insertion rod 13 to be inserted downward, which can better dislodge the fertilizer blocking the fertilization channel 201.

[0033] like Figure 5 As shown, the metering cylinder assembly 5 includes a first metering cylinder 501 and a second metering cylinder 502. The first metering cylinder 501 is connected to the storage tank 4 and has an open lower end. The second metering cylinder 502 has an open upper end and is fitted over the first metering cylinder 501. The lower part of the second metering cylinder 502 is connected to the connecting pipe assembly 6. The first metering cylinder 501 and the second metering cylinder 502 can form a complete metering cylinder. At the same time, the upper end is connected to the storage tank 4, and the lower end is connected to the inside of the shovel handle 1 through the connecting pipe assembly 6, which is used for the quantitative temporary storage of fertilizer.

[0034] like Figure 5 and Figure 6 As shown, an adjustment assembly is provided between the first metering cylinder 501 and the second metering cylinder 502, and the outer surface of the first metering cylinder 501 is provided with a scale 503;

[0035] The adjusting assembly includes a bolt 504 and a nut 505. The bolt 504 is rotatably connected to the outside of the first metering cylinder 501, and the nut 505 is fixed to the outside of the second metering cylinder 502. The bolt 504 and the nut 505 are threadedly connected.

[0036] When it is necessary to adjust the amount of fertilizer applied, the second metering cylinder 502 can be moved up or down on the first metering cylinder 501 by turning the bolt 504 connected to the nut 505. This allows the volume of the metering cylinder composed of the second metering cylinder 502 and the first metering cylinder 501 to be adjusted. As a result, the amount of fertilizer falling into the metering cylinder assembly 5 and the connecting pipe assembly 6 can be adjusted, thereby achieving the purpose of adjusting the amount of fertilizer according to actual usage needs. This makes the amount of fertilizer more accurate, which is beneficial to the growth of crops and improves the flexibility and adaptability of the fertilizer application device.

[0037] Furthermore, the setting of scale 503 allows for more precise identification of the position of the second metering cylinder 502 during the adjustment process, thereby facilitating more accurate adjustment and control of fertilizer metering.

[0038] like Figure 5 and Figure 6 As shown, the connecting pipe assembly 6 includes a conduit 601, a connecting pipe 602, and a connecting cap 603. The conduit 601 is made of soft material and is connected to the second metering cylinder 502. The connecting pipe 602 is fixed to the outside of the shovel handle 1 and the two are connected. A splitting component is provided between the connecting pipe 602 and the conduit 601, so that the conduit 601 and the connecting pipe 602 can be separated. Therefore, when fertilizer is blocked in the conduit 601 and the connecting pipe 602, the user can easily unclog it.

[0039] The split assembly comprises a connecting cover 603 and a connecting ring 604, the connecting ring 604 is arranged on the conduit 601, the connecting cover 603 is sleeved outside the connecting ring 604 and is threadedly connected with the connecting pipe 602, and the conduit 601 and the connecting pipe 602 are threadedly connected, so that the split between the conduit 601 and the connecting pipe 602 is more convenient and fast, the dredging work between the conduit 601 and the connecting pipe 602 is easier to operate, the structure of the connecting pipe assembly 6 is simpler, and the practicability is improved and the manufacturing cost is reasonably controlled.

[0040] As shown in Figure 4 The switch assembly 8 comprises a connecting piece 801, a blocking plate 802, a second elastic piece 803 and a connecting rope 805, the connecting piece 801 is provided with a through hole 806 for connecting the storage box 4 and the quantitative cylinder assembly 5, the blocking plate 802 is slidingly connected in the connecting piece 801, the second elastic piece 803 is arranged between the blocking plate 802 and the connecting piece 801, the connecting rope 805 is connected between the blocking plate 802 and the sliding rod 10, and the connecting piece 801 is provided with a pulley 804 connected with the connecting rope 805.

[0041] When the fertilizer is not applied, the blocking plate 802 deviates from the through hole 806, and at this time, the through hole 806 connects the storage box 4 and the quantitative cylinder assembly 5, and when the fertilizer is applied, the pull rod 11 is pulled upwards and the sliding rod 10 is slid upwards, the sliding rod 10 also pulls the blocking plate 802 to slide through the connecting rope 805, and the blocking plate 802 is slid to the through hole 806, so that the through hole 806 is blocked, and the fertilizer in the quantitative cylinder assembly 5 and the connecting pipe assembly 6 is prevented from continuously entering the storage box 4 when falling into the fertilizer pit.

[0042] Moreover, in the process of pulling the blocking plate 802 to slide, the blocking plate 802 also stretches and stores power to the second elastic piece 803, when the pull rod 11 is released, in the process of the sliding rod 10 resetting downwards, the second elastic piece 803 also pulls the blocking plate 802 back to the original position, so that the through hole 806 is opened again, and the fertilizer in the storage box 4 can enter the quantitative cylinder assembly 5 and the connecting pipe assembly 6 through the through hole 806, and the quantitative fertilization for the next time is performed.

[0043] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
