Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying device technology, and in particular to a fertilizer spraying device for soil fertilization. Background Technology
[0002] Soil enrichment is a process of improving soil fertility, building a good soil structure, cultivating a fertile topsoil layer, and enhancing soil productivity through human intervention. One common method is to spray granular fertilizers onto the soil.
[0003] A search revealed that a portable fertilizer spraying device disclosed in patent CN104054444B is not suitable for farmers in some areas who still choose to manually scoop granular fertilizer to save costs. Although this fertilizer spraying device is convenient for farmers to carry and spray, its overall production cost is still relatively high. It requires accessories such as motors and batteries, making it unsuitable for this group of farmers.
[0004] To address the aforementioned problems, this utility model document proposes a fertilizer spraying device for soil fertilization. Utility Model Content
[0005] This utility model provides a fertilizer spraying device for soil enrichment, which solves the shortcomings of the existing technology. In order to save costs, some farmers still choose to manually spread granular fertilizer. Although the fertilizer spraying device is convenient for farmers to carry and move for spraying, the overall production cost is still high. It also requires accessories such as motors and batteries, making it unsuitable for this type of farmer group.
[0006] This utility model provides the following technical solution:
[0007] A fertilizer spraying device for soil enrichment includes:
[0008] A backing plate is provided, and a fixed seat is fixedly installed on the outer wall of the backing plate. A storage bucket for storing granular fertilizer is snapped into the cavity at the top of the fixed seat. Two corrugated pipes are symmetrically connected to the outer wall of the storage bucket. A rigid pipe is detachably installed at the other end of the corrugated pipe. An installation port is provided on the rigid pipe. A baffle for sealing is installed in the installation port by means of a torsion spring.
[0009] In one possible design, two sets of adjustable shoulder straps are fixedly installed on the inner wall of the backrest.
[0010] In one possible design, a corresponding lid is snapped onto the top opening of the storage hopper.
[0011] In one possible design, two first handles are symmetrically fixed on the outer wall of the storage hopper.
[0012] In one possible design, two second handles are fixedly mounted on the top of the bucket lid.
[0013] In one possible design, the mounting base is provided with a notch for the bellows to pass through.
[0014] In one possible design, the rigid tube is threadedly connected to the internal thread of the bellows at the other end via an external thread at one end.
[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
[0016] The working principle and usage process of this technical solution are as follows:
[0017] When in use, the operator holds the first handle to snap the storage bucket into the cavity at the top of the fixed base. Then, the two corrugated pipes are passed through the corresponding notches on the fixed base, and the two rigid pipes are threaded to the corresponding corrugated pipes through the external threads at the ends. After that, the operator holds the second handle to open the bucket lid, pours the granular fertilizer into the storage bucket, and then closes the lid. At this time, the openings of the two rigid pipes should be facing upwards to prevent the granular fertilizer from leaking out. Then, the operator carries the backboard on their back through the shoulder straps to make the device easy to carry and move. The length of the shoulder straps can be adjusted according to actual needs to ensure comfortable carrying.
[0018] After the farmer carries the device to the soil area that needs fertilization, they hold the rigid pipe with their hand facing upwards and tilt the pipe opening downwards. The granular fertilizer flows out from the storage tank through the corrugated pipe and the rigid pipe, thus spraying the fertilizer. During spraying, the farmer presses the baffle with their thumb, causing it to rotate around the pivot point into the installation port to block the fertilizer flow, thereby controlling the flow of granular fertilizer. When the baffle is completely pressed against the inner wall of the rigid pipe, it can block the pipe and prevent the granular fertilizer from continuing to flow out. After the farmer stops pressing the baffle, the baffle will automatically return to its original position under the action of the torsion spring, restoring the maximum flow rate.
[0019] This utility model has the following beneficial effects:
[0020] This utility model has a simple structure and low cost, which greatly reduces production costs and is suitable for some farmers who still choose manual fertilization in order to save costs.
[0021] During the spraying process, farmers can control the flow rate of granular fertilizer by pressing the baffle with their thumb; the corrugated pipe connected to the outer wall of the storage tank is flexible and can adjust the position and angle of the rigid pipe according to the actual fertilization situation, making it convenient to carry out fertilization operations in different areas.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0030] Example 1
[0031] Please refer to Figures 1-4 A spraying device includes a backing plate 1, a fixed base 3, a storage tank 4, and spraying components:
[0032] The backrest 1 is a vertically set plate structure. Two sets of adjustable shoulder straps 2 are fixedly installed on its inner wall. The operator can adjust the length of the shoulder straps 2 to achieve a comfortable carrying fit. A fixing seat 3 is welded to the middle of the outer wall of the backrest 1. The top of the fixing seat 3 is a rectangular cavity. The bottom outer edge of the storage bucket 4 is interference-fitted with the cavity to achieve a snap-fit fixation. A matching bucket lid 5 is snapped at the top opening of the storage bucket 4. Two second handles 7 are welded to the top surface of the bucket lid 5. Two first handles 6 are symmetrically welded to the outer wall of the storage bucket 4 to facilitate the operator's gripping and picking up.
[0033] Two corrugated pipes 8 are symmetrically connected to the lower part of the outer wall of the storage hopper 4. Two U-shaped notches 9 are correspondingly opened on the side wall of the fixing seat 3. The corrugated pipes 8 are inserted into the notches 9 and maintain freedom of movement. Due to the flexibility of the corrugated pipes 8, the operator can adjust the position and angle of the rigid pipe 10 according to the actual fertilization situation, which is convenient for fertilization operations in different areas. Each corrugated pipe 8 has an internal thread 14 at the end and an external thread 13 at the front end. The two are detachably connected by threaded connection. An installation port 11 is opened on the body of the rigid pipe 10. A baffle 12 is installed in the installation port 11 by rotating a pin. A torsion spring is installed on the pin. Keep the baffle 12 closed. When the baffle 12 is pressed down against the inner wall of the rigid pipe 10, the inner cavity of the rigid pipe 10 can be completely blocked. During the spraying process, the operator can control the flow rate of the granular fertilizer by pressing the baffle 12 with his thumb. When pressed, the baffle 12 rotates into the installation port 11 with the pivot as the center, blocking part of the fertilizer from flowing out, thereby reducing the fertilizer flow rate. When the thumb presses the baffle 12 until it is completely against the inner wall of the rigid pipe 10, the pipeline of the rigid pipe 10 can be blocked to prevent the granular fertilizer from continuing to flow out. When it is necessary to restore the maximum flow rate, simply stop pressing the baffle 12, and the baffle 12 will automatically reset under the action of the torsion spring.
[0034] In actual use, the operator holds the first handle 6 with both hands and vertically places the storage tank 4 into the cavity of the fixed base 3, so that the corrugated pipe 8 hangs down naturally through the corresponding notch 9. The external threads 13 at the front end of the two rigid pipes 10 are screwed into the internal threads 14 at the end of the corrugated pipe 8 to complete the assembly of the spraying component. The tank cover 5 is opened through the second handle 7, granular fertilizer is put into the storage tank 4, and the tank cover 5 is closed again. At this time, the pipe opening of the rigid pipe 10 is kept in an upward position to prevent fertilizer leakage.
[0035] When carrying the fertilizer, the operator places the shoulder straps 2 over both shoulders and the backrest 1 against the back. By adjusting the length of the shoulder straps 2, the center of gravity of the storage tank 4 is aligned with the waist. After moving to the fertilization area, the operator holds a rigid pipe 10 in each hand and tilts the pipe opening downwards to a suitable angle. Under the action of gravity, the fertilizer in the storage tank 4 flows through the corrugated pipe 8 to the rigid pipe 10. When the flow rate needs to be adjusted, the operator presses the baffle 12 on the outside of the rigid pipe 10 with their thumb. The baffle 12 rotates around the pin and enters the installation port 11. Its plate surface forms an angle with the inner wall of the rigid pipe 10. The flow area is adjusted by controlling the pressing depth. After releasing the thumb, the baffle 12 automatically returns to the maximum opening under the action of the torsion spring.
[0036] When it is necessary to adjust the spraying direction, the corrugated pipe 8 can be bent to change the direction of the rigid pipe 10. The expansion and contraction characteristics of the corrugated pipe 8 allow the rigid pipe 10 to be freely positioned within a horizontal range of 360 degrees and a vertical range of 180 degrees. After fertilization, the rigid pipe 10 is placed with the pipe opening facing upwards, and the residual fertilizer automatically flows back to the storage tank 4. After disassembling the rigid pipe 10, the corrugated pipe 8 and the rigid pipe 10 can be cleaned and maintained.
[0037] This application can be used for spraying granular fertilizers, or for other fields applicable to this application.

[0040] A fertilizer spraying device for soil enrichment, which is used in the field of spraying devices;
[0041] Please refer to Figures 1-2 The adjustable shoulder strap 2 adopts the shoulder strap structure of a regular backpack. This structure is usually simple, practical and durable. Users can easily adjust the length of the shoulder strap by operating the adjustment buckle. When the shoulder strap length needs to be increased, slide the adjustment buckle towards one end of the shoulder strap body or unbuckle the buckle; when the shoulder strap length needs to be shortened, slide the adjustment buckle towards the other end or fasten the buckle.
