Description

Technical Field

[0001] This utility model belongs to the field of blueberry cultivation technology, and specifically relates to a quantitative fertilizer applicator for blueberry cultivation. Background Technology

[0002] Blueberry cultivation is the process of developing blueberry plants from seedlings to mature fruit trees through a series of technical means. Blueberries are oligotrophic plants with very low levels of nitrogen, phosphorus, potassium, calcium, and magnesium in their bodies. Excessive fertilization can easily lead to fertilizer accumulation, causing root damage or even plant death. Generally, they are cultivated in petri dishes and fertilized in a fixed amount.

[0003] In current technologies, manual fertilization is the most common method. However, manual fertilization relies heavily on experience, with fertilizer being scooped and scattered by feel. This method cannot guarantee the consistency and accuracy of fertilizer application for each blueberry plant, easily leading to uneven fertilization. Over-fertilization can cause root burn, while under-fertilization can cause malnutrition in the plants, ultimately resulting in a decrease in blueberry yield and quality.

[0004] Secondly, the operation is cumbersome and the production efficiency is low. Throughout the fertilization process, workers need to repeatedly perform mechanical actions, which is not only labor-intensive and inefficient, but also lacks a quick and intuitive adjustment mechanism when it is necessary to adjust the amount of fertilizer to suit different growth stages of blueberries. The only way to achieve this is by changing containers or doubling the estimate, which further increases the complexity and uncertainty of the operation.

[0005] In addition, existing tools are prone to fertilizer spillage during movement and spreading, which not only wastes fertilizer but also causes fertilizer damage because fertilizer adheres to plant leaves. At the same time, some specialized fertilizer applicators on the market have complex structures, high costs, and inconvenient quantitative adjustment mechanisms, making it difficult to popularize their application in large-scale planting.

[0006] Therefore, there is an urgent need for a specialized tool with a simple structure, convenient operation, and the ability to accurately quantify and flexibly adjust the amount of fertilizer applied, in order to solve the core pain points in blueberry cultivation, such as inaccurate fertilization, high labor intensity, and low fertilizer utilization. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative fertilizer applicator for blueberry cultivation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a blueberry cultivation quantitative fertilizer applicator, comprising a cultivation dish, a fertilizer and water trough provided on one side of the cultivation dish, a fertilizer applicator body provided on the surface of the fertilizer and water trough, an adjusting triangular piece provided on the inner wall of the fertilizer applicator body, a fertilizer storage piece detachably connected to the side of the fertilizer applicator body away from the cultivation dish by bolts, a feeding pipe fixed to the side of the fertilizer storage piece near the fertilizer applicator body; an L-shaped operating plate slidably connected to the inner wall of the side of the fertilizer applicator body near the fertilizer storage piece, a metering cylinder fixed to the side of the L-shaped operating plate away from the fertilizer storage piece, a shaft fixed to the circumference of the metering cylinder away from the L-shaped operating plate and close to the fertilizer applicator body, and an auxiliary cover rotatably connected to the surface of the shaft.

[0009] Preferably, a reset plate is fixed on the side of the L-shaped operating plate away from the fertilizer storage component, and a reset spring is fixed on one side of the reset plate. A finite circular groove is formed on the side of the fertilizer applicator near the reset plate, and one end of the inner wall of the finite circular groove is fixed to one end of the reset spring.

[0010] Preferably, the fertilizing body has a limiting groove on both sides of the inner wall near the parallel section of the L-shaped operating plate, and a limiting wing plate is slidably connected to the inner wall of the limiting groove. One side of the limiting wing plate is fixed to both sides of the parallel section of the L-shaped operating plate.

[0011] Preferably, the L-shaped operating plate is provided with a cutting groove on the side near the feed pipe, and the edge of the adjusting triangle near the auxiliary cover is provided as an auxiliary inclined surface.

[0012] Preferably, a positioning light is fixed at the end of the parallel section of the L-shaped operating plate away from the cutting ring groove.

[0013] Preferably, the two sides of the adjusting triangle are slidably connected to the inner wall of the fertilizer body, and a spring insert is fixed on the side of the adjusting triangle near the fertilizer body. The inner wall of the fertilizer body near the adjusting triangle is provided with a plurality of arc grooves that correspond to the spring inserts in a linear array.

[0014] Preferably, a limiting ladder is fixed on the side of the adjusting triangle near the fertilizer body, and a limiting ladder groove is provided on the side of the fertilizer body near the adjusting triangle, with the inner wall of the limiting ladder groove slidably connected to the surface of the limiting ladder.

[0015] Preferably, the fertilizer applicator is fixed with an installation clip on the side away from the adjusting triangle.

[0016] In summary, this utility model has the following beneficial effects: 1. This utility model uses an L-shaped operating panel, which allows the operator to push the L-shaped operating panel to drop a fixed amount of fertilizer from the metering cylinder into the fertilizer tank. The operator can also change the metering by changing different models of metering cylinders and adjusting the position of the adjusting triangle, thereby facilitating the operator's operation and improving the uniformity of fertilization and the scope of application. 2. This utility model uses a reset spring and a reset plate to allow the L-shaped operating plate to automatically retract after the operator releases their grip, thus facilitating operation. At the same time, the limiting groove and limiting wing plate ensure that the L-shaped operating plate maintains stable movement during reset, preventing deviation and improving the service life of the equipment. 3. This utility model uses a positioning light to help workers locate the L-shaped operating panel when the blueberry leaves are dense. When the worker pushes the L-shaped operating panel a certain distance, the positioning light contacts the feeding pipe to prevent the L-shaped operating panel from moving too far and causing equipment damage.

Detailed Implementation

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example 1: refer to Figures 1-8 A quantitative fertilizer applicator for blueberry cultivation includes a cultivation dish 1. A fertilizer trough 101 is provided on one side of the cultivation dish 1. A fertilizer application body 2 is provided on the surface of the fertilizer trough 101. An adjusting triangular piece 7 is provided on the inner wall of the fertilizer application body 2. A fertilizer storage piece 201 is detachably connected to the side of the fertilizer application body 2 away from the cultivation dish 1 by bolts. A feeding pipe 203 is fixed to the side of the fertilizer storage piece 201 near the fertilizer application body 2. An L-shaped operating plate 202 is slidably connected to the inner wall of the side of the fertilizer application body 2 near the fertilizer storage piece 201. A metering cylinder 204 is fixed to the side of the L-shaped operating plate 202 away from the fertilizer storage piece 201. A shaft 206 is fixed to the periphery of the metering cylinder 204 away from the L-shaped operating plate 202 and close to the fertilizer application body 2. An auxiliary cover 205 is rotatably connected to the surface of the shaft 206.

[0021] Specifically, fertilizer is metered and temporarily stored using the metering cylinder 204. When the operator pushes the L-shaped operating plate 202, the metering cylinder 204 moves to one side. At the same time, the subsequent L-shaped operating plate 202 blocks the feed pipe 203 to prevent it from falling. Simultaneously, the metering cylinder 204, which has left the fertilizer application body 2, opens due to the rotation of the auxiliary cover 205 via the shaft 206. The small spherical fertilizer particles in the metering cylinder 204 leave the metering cylinder 204 and enter the fertilizer tank 101, thus facilitating the metering application by the operator. The operator can remove the bolts fixing the L-shaped operating plate 202 and the metering cylinder 204 with a screwdriver to replace different metering cylinders 204. The height of the triangular piece 7 can be adjusted by sliding it up and down to accommodate metering cylinders 204 of different lengths, ensuring that the auxiliary cover 205 can be reliably lifted and closed when reset.

[0022] A reset plate 302 is fixed on the side of the L-shaped operating plate 202 away from the fertilizer storage component 201. A reset spring 301 is fixed on one side of the reset plate 302. A limiting circular groove 3 is opened on the side of the fertilizer application body 2 close to the reset plate 302. One end of the inner wall of the limiting circular groove 3 is fixed to one end of the reset spring 301.

[0023] The fertilizer body 2 has a limiting groove 4 on both sides of the inner wall of the parallel section of the L-shaped operating plate 202. A limiting wing plate 401 is slidably connected to the inner wall of the limiting groove 4. One side of the limiting wing plate 401 is fixed to both sides of the parallel section of the L-shaped operating plate 202.

[0024] Specifically, the L-shaped operating plate 202 can automatically retract after the operator releases their hand via the reset spring 301 and the reset plate 302, making it easier for the operator to operate. At the same time, the limiting groove 4 and the limiting wing plate 401 ensure that the L-shaped operating plate 202 maintains stable movement during reset, preventing deviation and improving the service life of the equipment.

[0025] The L-shaped operating plate 202 is provided with a cutting groove 5 on the side near the feed pipe 203, and the edge of the adjusting triangle 7 near the auxiliary cover 205 is provided as an auxiliary inclined surface 501.

[0026] Specifically, when the feed pipe 203 is not fully aligned with the metering cylinder 204 hole of the L-shaped operating plate 202, the cutting groove 5 acts as a guide, allowing fertilizer to enter the metering cylinder 204 and preventing fertilizer spillage. At the same time, when the L-shaped operating plate 202 is reset, the auxiliary inclined surface 501 guides the shaft 206, allowing the shaft 206 to smoothly and with low wear close to the metering cylinder 204, thus improving the service life of the equipment.

[0027] A positioning light 6 is fixed at the end of the parallel section of the L-shaped operating panel 202 that is away from the cutting groove 5.

[0028] Specifically, the positioning light 6 helps the operator to position the L-shaped operating plate 202 when the blueberry leaves are dense. When the operator pushes the L-shaped operating plate 202 a certain distance, the positioning light 6 contacts the feeding pipe 203 to prevent the L-shaped operating plate 202 from moving too far and causing equipment damage.

[0029] The two sides of the adjusting triangle 7 are slidably connected to the inner wall of the fertilizer body 2. A spring insert 702 is fixed on the side of the adjusting triangle 7 near the fertilizer body 2. Multiple arc grooves 701 corresponding to the spring insert 702 are linearly arranged on the side of the inner wall of the fertilizer body 2 near the adjusting triangle 7.

[0030] Specifically, through the cooperation of the spring insert 702 and the recessed groove 701, when the operator needs to adjust the height of the adjusting triangle 7, he only needs to push or press the adjusting triangle 7 to make the spring insert 702 overcome its own elasticity, generate elastic deformation and release elastic potential energy to embed into the appropriate recessed groove 701, thereby positioning the adjusting triangle 7 at the appropriate height, which is convenient for the operator to adjust.

[0031] A limiting ladder component 801 is fixed on the side of the adjusting triangular component 7 near the fertilizer body 2. A limiting ladder groove 8 is opened on the side of the fertilizer body 2 near the adjusting triangular component 7. The inner wall of the limiting ladder groove 8 is slidably connected to the surface of the limiting ladder component 801.

[0032] Specifically, by limiting the sliding between the ladder groove 8 and the limiting ladder member 801, the sliding path of the adjusting triangle member 7 is limited, so that it always slides vertically, preventing the offset caused by resistance when changing the embedded arc groove 701 of the spring insert 702, thereby improving the stability of the equipment.

[0033] The fertilizer applicator 2 is fixed with an installation clip 9 on the side away from the adjusting triangle 7.

[0034] Specifically, by installing clip 9, the fertilizer application unit 2 can be quickly and conveniently deployed in different culture dishes 1, which facilitates operation by staff while simplifying the structure and reducing production costs.

[0035] Example 2: refer to Figures 1-8 Staff members used the structure disclosed in this utility model in a smart greenhouse at a blueberry planting base in Shandong. Technicians are fertilizing a three-year-old "Bluecrop" variety during its flower bud differentiation period. A quantitative fertilizer applicator for blueberry cultivation is used, with the fertilizer applicator 2 fixed to the side wall of the culture dish 1 by a mounting clip 9. The fertilizer storage unit 201 is filled with acidic compound fertilizer with a pH of 4.5.

[0036] The technicians selected a 5 ml metering cylinder 204 and adjusted the adjusting triangle 7 to the second position. At this time, the spring insert 702 was engaged in the corresponding groove 701 and made a crisp sound.

[0037] When the L-shaped operating panel 202 is pressed, the return spring 301 is compressed to the bottom of the limiting groove 3, and the metering cylinder 204 moves smoothly to the left by 15 mm along the limiting groove 4. The auxiliary cover 205 opens under the action of the shaft 206, accurately dispensing 0.8 grams of fertilizer into the fertilizer tank 101. The positioning light 6 contacts the feeding pipe 203 at the end of its stroke to form a mechanical limit.

[0038] Upon release, the return spring 301 provides a 15-Newton restoring force to reset the mechanism, and the auxiliary cover 205 automatically closes under the guidance of the auxiliary inclined surface 501. When switching to blueberries in their peak fruiting period, technicians only need to replace the 10-ml measuring cylinder and raise the adjusting triangle 7 to the fourth position to achieve precise fertilization of 1.5 grams each time.

[0039] This device reduces the fertilization time for 200 blueberry plants to 12 minutes, increases fertilizer utilization to 92%, and reduces the coefficient of variation in fertilizer application between plants to no more than 3%.

[0040] The working principle of this utility model: Step 1: Secure the fertilizer applicator 2 to the fertilizer tank 101 next to the culture dish 1 using the mounting clip 9. The fertilizer storage unit 201 has a detachable fertilizer container on top. Under the elastic force of the return spring 301, the L-shaped operating plate 202 is in its initial position, usually the rightmost position. At this time, the upper opening of the metering cylinder 204 is aligned with the outlet of the feed pipe 203.

[0041] Fertilizer flows from the fertilizer storage unit 201 through the discharge pipe 203 and falls into the metering cylinder 204 by gravity until it is full. The cutting groove 5 on the L-shaped operating plate 202 ensures that even with slight misalignment, the fertilizer can smoothly enter the metering cylinder 204. At the same time, the auxiliary cover 205 remains closed under the fertilizer application body 2 to prevent fertilizer leakage.

[0042] Step 2: The operator pushes the vertical section of the L-shaped operating plate 202 by hand to overcome the elastic force of the return spring 301, causing it to slide to the left, away from the storage component 201. This restricts the sliding of the wing plate 401 within the restrictive groove 4, ensuring smooth movement of the operating plate without deviation.

[0043] The moment the L-shaped control panel 202 moves, it cuts off the connection between the feed pipe 203 and the metering cylinder 204, preventing further fertilizer filling. Simultaneously, as the metering cylinder 204 moves to the left, the shaft 206 rotates, causing the auxiliary cover 205 to open around the shaft 206, revealing the fertilizer discharge port at the bottom of the metering cylinder 204. Under gravity, the fertilizer inside the metering cylinder 204 is poured into the fertilizer tank 101 below through the opened discharge port, completing a precise fertilization.

[0044] During the pushing process, the positioning light 6 fixed on the L-shaped operating plate 202 will eventually come into contact with the feeding tube 203, which will play a physical limiting role and prevent the equipment from being damaged by excessive operating stroke.

[0045] Step 3: After the fertilization operation is completed, the operator releases the L-shaped operating plate 202. The compressed return spring 301 releases its elastic potential energy, pushing the return plate 302 and the connected L-shaped operating plate 202 to slide quickly back to the initial position to the right. During the reset process, the auxiliary cover 205 first contacts the auxiliary inclined surface 501 of the adjusting triangle 7, and rotates in the opposite direction under the guidance of the inclined surface, causing the auxiliary cover 205 to close automatically, preparing for the next material receiving.

[0046] Once the metering cylinder 204 returns to its initial position and aligns with the feed pipe 203, the fertilizer begins to fill the metering cylinder 204 again, awaiting the next operation.

[0047] Step 4: The adjusting triangular piece 7 can slide vertically on the inner wall of the fertilizer applicator 2. The spring insert 702 on its back can be inserted into the arc groove 701 of different heights to achieve multi-point fixation, thereby adapting to different height metering cylinders 204.

[0048] The limiting ladder component 801 slides within the limiting ladder groove 8, ensuring that the adjusting triangle component 7 maintains vertical movement during the adjustment process and does not wobble left or right.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
