Description

Technical Field

[0001] This utility model relates to the field of forestry equipment technology, specifically to a forestry ecological restoration fertilization device. Background Technology

[0002] Fertilization refers to agricultural techniques that apply fertilizer to the soil or spray it on plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil, and improve economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain the sustainable development of agriculture.

[0003] During the cultivation of forestry seedlings, fertilization is necessary. Existing fertilization devices are mostly of two types: manual backpack fertilization and large vehicle-mounted fertilization devices. However, vehicles are bulky, requiring large access roads and are inconvenient to use in areas with poor transportation; turning is also difficult. Manual fertilization is labor-intensive and inconvenient. While traditional push-type fertilization machines can fertilize in areas with poor transportation, their fertilization area is limited, making them unsuitable for large-scale applications. When fertilizing a large area, it needs to be repeated multiple times, which is less efficient than vehicle-mounted fertilizers. While extending the fertilizer hose of a hand-push fertilizer can improve fertilization efficiency, the longer hose will cause uneven pressure at the beginning and end of the hose, resulting in uneven fertilizer spraying and uneven plant growth in the same area. On the other hand, reducing the diameter of the nozzle on the fertilizer hose can balance the pressure at the beginning and end of the hose, but the smaller nozzle is more prone to clogging by fertilizer, affecting the spraying effect. Utility Model Content

[0030] like Figure 1-4 As shown, a forestry ecological restoration fertilization device includes:

[0031] Fertilizer tank 10; a fertilizer pump is installed inside the fertilizer tank 10;

[0032] The fertilization assembly 20 includes a rotating seat 201 disposed on the side of the fertilizer tank 10, a fertilization pipe 202 rotatably connected to the rotating seat 201, and a connecting pipe 203 connecting the fertilization pipe 202 and the fertilizer tank 10. The lower end face of the fertilization pipe 202 is evenly provided with a plurality of openings along the length direction. The fertilizer pump is adapted to pump fertilizer from the fertilizer tank 10 into the fertilization pipe 202 through the connecting pipe 203.

[0033] The spraying assembly 30, installed in the fertilizer pipe 202, includes a spray pipe 301, a sealing seat 302, a guide seat 303, a guide rod 304, a first elastic element 305, and a sealing element 306. The spray pipe 301 extends downward or upward from the opening edge. The sealing seat 302 and the guide seat 303 are spaced apart within the spray pipe 301. The guide rod 304 is disposed between the guide seat 303 and the sealing seat 302 and is slidably connected to the guide seat 303. The sealing element 306 is disposed on the guide rod 304 away from the guide seat. At one end of 303, the first elastic element 305 is sleeved on the outside of the guide rod 304, and the two ends of the first elastic element 305 abut against the sealing element 306 and the guide seat 303 respectively, so as to provide the sealing element 306 with elastic force to move toward the sealing seat 302. The sealing seat 302 has an inlet 3021 communicating with the connecting pipe 203. The sealing element 306 is adapted to block the inlet 3021 under the action of the elastic force of the first elastic element 305. The guide seat 303 has a plurality of outlets communicating with the outside evenly.

[0034] The base 40 is on which the fertilizer box 10 is mounted, and multiple rollers are installed on both sides of the base 40.

[0035] In use, fertilizer is placed in the fertilizer tank 10, then the fertilizer application tube 202 is unfolded, and the fertilizer pump is started. The fertilizer pump pumps fertilizer from the fertilizer tank 10 into the fertilizer application tube 202 until the fertilizer application tube 202 is full. Under the pressure in the fertilizer application tube 202, the sealing member 306 moves toward the guide seat 303 to open the inlet 3021 on the sealing seat 302. The fertilizer will flow into the spray pipe 301 through the inlet 3021 and be sprayed out through the opening on the guide seat 303 to fertilize the plants below.

[0036] This invention uses a sealing seat 302, a guide seat 303, a guide rod 304, a first elastic element 305, and a sealing element 306 to seal the fertilizer application pipe 202. When the pressure inside the fertilizer application pipe 202 reaches a certain value, the spray nozzle 301 is opened to ensure uniform discharge from each outlet, preventing uneven flow. Furthermore, the first elastic element 305 can control the sealing element 306 to move towards the sealing seat 302 when the pressure inside the fertilizer application pipe 202 decreases, thereby adjusting the fertilizer flow rate entering from the inlet 3021 and preventing a rapid decrease in pressure inside the fertilizer application pipe 202 that could lead to flow interruption.

[0037] Furthermore, to improve the sealing performance of the sealing element 306, in this embodiment, the sealing seat 302 has a conical groove on the side facing the sealing element 306, the inlet 3021 is opened at the bottom of the conical groove, and the sealing element 306 is in the shape of a frustum adapted to the conical groove. With this arrangement, the sealing element 306 can easily cooperate with the first elastic element 305 to adaptively adjust the flow rate of fertilizer entering from the inlet 3021.

[0038] Furthermore, to improve fertilization efficiency, in this embodiment, the fertilization pipe 202 includes a first pipe 2021 rotatably connected to the rotating seat 201 and a second pipe 2022 sleeved inside the first pipe 2021 and slidable relative to the first pipe 2021. The second pipe 2022 is slidably sealed to the first pipe 2021. The lower end faces of the first pipe 2021 and the second pipe 2022 are evenly provided with a plurality of openings along the length direction. The spray pipe 301 in the spraying assembly 30 installed in the first pipe 2021 extends downward along the edge of the opening, and the spray pipe 301 in the spraying assembly 30 installed in the second pipe 2022 extends upward along the edge of the opening.

[0039] Since the second fitting 2022 is fitted inside the first fitting 2021, it can be pulled out from the first fitting 2021 during use, thereby extending the overall length of the fertilizer pipe 202 and increasing the fertilization area. When the fertilization area is small, the first fitting 2021 can be used directly without pulling out the second fitting 2022.

[0040] Furthermore, to prevent the wall of the second pipe 2022 from blocking the opening of the first pipe 2021 when the second pipe 2022 is placed inside the first pipe 2021, in this embodiment, the opening of the second pipe 2022 is aligned with the opening of the first pipe 2021 so that the fertilizer can flow through the opening of the second pipe 2022 to the opening of the first pipe 2021, and then be sprayed out through the spraying assembly 30 installed on the first pipe 2021, without affecting the spraying of the fertilizer.

[0041] Meanwhile, to prevent the fertilizer pipe 202 from breaking due to excessive length, this embodiment also includes a support component 50. The support component 50 includes a fixed seat 501 installed at the end of the second pipe 2022 away from the first pipe 2021 and a support rod installed at the fixed seat 501. During operation, the support rod located at the end of the second pipe 2022 will directly contact the ground, thereby providing support for the end of the second pipe 2022 to prevent the first pipe 2021 and the second pipe 2022 from breaking under the action of gravity.

[0042] To enable the support rod to adapt to uneven terrain, in this embodiment, the support rod includes a support base 505, a first rod body 502, a second rod body, and a second elastic element 503. The top end of the first rod body 502 is fixedly connected to the fixed base 501, and a groove is formed at the bottom end of the first rod body 502. The top end of the second rod body is fitted into the groove and can slide relative to the groove. The support base 505 is installed at the bottom end of the second rod body, and the second elastic element 503 is fitted onto the outside of the second rod body, with both ends of the second elastic element 503 abutting against the support base 505 and the first rod body 502, respectively. Of course, to facilitate the movement of the support assembly 50, in this embodiment, the support base 505 can also be replaced with a caster wheel.

[0043] Furthermore, to facilitate the extension of the second pipe fitting 2022 out of the first pipe fitting 2021, this embodiment also includes a drive assembly 60. The drive assembly 60 includes a drive motor 601 mounted on the first pipe fitting 2021, a drive seat 602 mounted on the second pipe fitting 2022, a drive screw 603 mounted on the drive shaft of the drive motor 601, and a drive sleeve 604 fixedly mounted on the drive seat 602 and threadedly connected to the drive screw 603. During operation, the drive motor 601 drives the drive screw 603 to rotate, thereby causing the drive sleeve 604 to move relative to the drive screw 603, thus causing the second pipe fitting 2022 to extend or retract from the first pipe fitting 2021. At the same time, the drive screw 603 and the drive sleeve 604 can provide support for the second pipe fitting 2022, thereby reducing the probability of the first pipe fitting 2021 and the second pipe fitting 2022 breaking under gravity.

[0044] To facilitate fertilizer mixing by staff, this embodiment also includes a mixing component 70. The mixing component 70 includes a mixing cylinder 701, a mixing motor 702, a mixing rod 703, a conveying pipe 704, a conveying pump 705, and multiple mixing blades 706. The mixing motor 702 is installed at the top of the mixing cylinder 701. The mixing rod 703 is disposed inside the mixing cylinder 701 and is drivenly connected to the main shaft of the mixing motor 702. The multiple mixing blades 706 are evenly arranged along the length of the mixing rod 703. The top of the mixing cylinder 701 is provided with a feed inlet. The conveying pump 705 is installed at the top of the fertilizer tank 10, and the discharge end of the conveying pump 705 is connected to the fertilizer tank 10. One end of the conveying pipe 704 is connected to the mixing cylinder 701, and the other end is connected to the feed inlet of the conveying pump 705.

[0045] When in use, the staff pours various fertilizers into the mixing drum 701 through the inlet, and then starts the mixing motor 702 to drive the mixing blades 706 through the mixing rod 703 to stir the fertilizer in the mixing drum 701. After the fertilizer in the mixing drum 701 is evenly mixed, the feed pump 705 is started to pump the mixed fertilizer into the fertilizer tank 10.

[0046] In addition, to facilitate the user in pushing the device, this embodiment also includes a handle 80, which is fixedly connected to the base 40.

[0047] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
