Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing and production technology, and in particular to a fertilizer pH adjustment device. Background Technology

[0002] Fertilizer is an important material basis in agricultural production. It is mainly used to provide plants with essential nutrients, improve soil properties, and increase soil fertility. Fertilizer pH refers to the acidity or alkalinity of chemical fertilizers. It is an indicator to measure the acidity or alkalinity of a chemical fertilizer solution. The pH value ranges from 0 to 14, where a pH value of 7 indicates neutrality, below 7 indicates acidity, and above 7 indicates alkalinity.

[0003] When fertilizing, the acidity or alkalinity of the fertilizer needs to be considered to ensure its effectiveness and the healthy growth of crops. Therefore, a fertilizer pH adjustment device is needed to ensure that the fertilizer pH value is within a reasonable range. For example, the existing technology, Chinese Patent Publication No. "CN113800970A", provides a formula for making organic fertilizer. The formula for making organic fertilizer includes the following ingredients: cow manure, cassava residue, straw, urea, organic fertilizer fermentation agent, superphosphate, and pH adjuster; the cow manure, cassava residue, straw, urea, organic fertilizer fermentation agent, superphosphate, and pH adjuster are used in the following component ratio: cow manure 30-40 parts, cassava residue 10-15 parts, straw 10-15 parts, urea 5-15 parts, organic fertilizer fermentation agent 5-10 parts, superphosphate 5-20 parts, and pH adjuster 6-20 parts. The organic fertilizer formula provided by this invention uses cow dung, straw, and cassava residue. The raw materials are easy to obtain, the production cost is low, and the prepared fertilizer is more suitable for plant growth, providing sufficient raw materials for plant growth and facilitating plant absorption, so that the plants can grow rapidly and vigorously. The plants can contain more water, which can make the fruits more plump when cultivating plants carrying fruit.

[0004] In practice, adjusting the pH value of fertilizers is often done by adding a quantitative amount of alkaline or acidic substances to neutralize and regulate the raw materials of the fertilizer. However, the lack of quantitative feeding measures can lead to the inability to accurately control the acidic or alkaline substances, which can easily cause the pH value of the fertilizer to change again, affecting the accuracy and efficiency of the adjustment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies in terms of the lack of quantitative feeding of acidic and alkaline substances, and to propose a fertilizer pH adjustment device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Design a fertilizer pH adjustment device, including a mixing tank and a hinged rotating top cover. A mixing device is installed inside the mixing tank, and a material box is connected to the top of the cover. The material box is used to store acidic and alkaline substances, and the acidic and alkaline substances are quantitatively fed through an internal metering component.

[0008] The quantitative component includes a feeding component and a driving component. The driving component is used to drive the feeding component to feed material, and the length of the feeding component is adjusted by a fixing component to control the feeding amount.

[0009] Furthermore, the material bins are provided in pairs, each pair of material bins being used to store acidic or alkaline substances, and each of them having a conical bottom structure and being rotatably connected to the feeding component, wherein the feeding component has a cylindrical structure and one end of it is recessed along the axis to form several feeding grooves.

[0010] Furthermore, the quantitative component also includes a stop and a bracket. The stop is rotatably connected to one side of the material box via two side stop plates. The stop is also provided with a relief groove. The end of the feeding component with the feeding groove is slidably connected to the relief groove.

[0011] Furthermore, the driving component is a motor, the bracket is fixed to the top of the box cover and is slidably connected to a slide plate via a pair of guide rods, the motor is fixed to the top of the slide plate and its shaft end is fixedly connected to the other end of the unloading component.

[0012] Furthermore, the fixing component includes a connecting rod that is threadedly connected to the slide plate, and has a handle and a rubber abutment at each end, the rubber abutment being able to press against the guide rod.

[0013] Furthermore, the bottom end of the connecting rod is provided with an annular groove, and the other end of the rubber abutment is provided with a circular groove. The circular groove extends from the opening side toward the axis to form an annular portion, and the annular portion engages with the annular groove.

[0014] The present invention provides a fertilizer pH adjustment device with the following advantages: The device includes a pair of hoppers connected to a mixing tank. These hoppers store acidic and alkaline substances and are equipped with a metering component. The pH value of the fertilizer raw material is adjusted by metering the acidic and alkaline substances using a feeding rod, which better meets the needs of specific plants or soils, thereby improving the fertilizer's absorption rate and effectiveness. Furthermore, the length of the feeding rod (i.e., the feeding trough) can be adjusted using a fixing component. Thus, at the same rotation speed, the amount of acidic and alkaline substances fed can be adjusted by changing the length of the feeding trough. The device is simple to operate and highly practical.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A fertilizer pH adjustment device includes a mixing tank 1 and a top hinged rotating cover 11. A mixing device 2 is provided inside the mixing tank 1, and a material box 3 is connected to the top of the cover 11. The material box 3 is used to store acidic and alkaline substances, and the acidic and alkaline substances are quantitatively fed through an internal metering component 4.

[0024] The quantitative component 4 includes a feeding component 41 and a driving component 42. The driving component 42 is used to drive the feeding component 41 to feed material, and the length of the feeding component 41 is adjusted by the fixing component 5 to control the feeding amount.

[0025] It should be added that the mixing tank 1 is mounted on a fixed frame, and the mixing device 2 includes a motor and a mixing rod. The motor is fixedly mounted on the side of the fixed frame, and the mixing rod is rotatably connected inside the mixing tank 1, with its shaft end passing through the mixing tank 1 and fixedly connected to the shaft end of the motor.

[0026] The top of the box cover 11 is provided with a feed pipe and a pair of material boxes 3. The fertilizer raw materials are transported to the mixing box 1 through the feed pipe, and the corresponding acid and alkaline substances are added to neutralize and adjust the pH value of the fertilizer raw materials. The acid and alkaline substances are acid regulators and alkaline regulators, specifically including ammonium sulfate, lime powder, etc.

[0027] Of course, the bottom of the mixing tank 1 is also equipped with a hopper, and the hopper is equipped with an electric valve.

[0028] Furthermore, the material bins 3 are provided in pairs, and the pair of material bins 3 are respectively used to store acidic or alkaline substances. Their bottoms have a conical structure and are rotatably connected to the feeding component 41. The feeding component 41 has a cylindrical structure, and one end of it is recessed along the axis to form several feeding grooves 411.

[0029] Furthermore, the quantitative component 4 also includes a stop part 43 and a bracket 44. The stop part 43 is rotatably connected to one side of the material box 3 via stop plates 431 on both sides. The stop part 43 is also provided with a relief groove 432. One end of the feeding component 41 with the feeding groove 411 is slidably connected to the relief groove 432. Of course, several sealing rings can also be added to the inner hole of the stop part 43 to prevent dust from overflowing from its inner hole. This method is a conventional method for those skilled in the art and will not be described in detail here.

[0030] It is worth mentioning that the stop part 43 has a circular structure. One of the stop plates 431 is integrally formed with the stop part 43, and the other stop plate 431 is detachably connected to the stop part 43 by bolts. The pair of stop plates 431 have the same structure and their areas are slightly larger than the stop part 43.

[0031] Among them, the pair of stop plates 431 respectively abut against the inner and outer sides of one side of the material box 3. This is to facilitate the disassembly and assembly of the stop part 43, and to limit the material feeding part 41 through the stop part 43, thereby controlling the effective capacity of the material feeding trough 411. The drive part 42 drives the material feeding part 41 to use the material feeding trough 411 for quantitative feeding.

[0032] Furthermore, the bottom of the material box 3 has a conical structure, and the feeding component 41 is located at this position and is fitted with the two sides of the material box 3 with a gap to prevent acidic and alkaline substances from entering the mixing tank 1 without passing through the feeding trough 411.

[0033] More specifically, the driving component 42 is a motor, the bracket 44 is fixed to the top of the box cover 11 and is slidably connected to the slide plate 442 by a pair of guide rods 441, the motor is fixed to the top of the slide plate 442 and its shaft end is fixedly connected to the other end of the unloading component 41.

[0034] It should be noted that the motor is preferably a servo motor. When the motor shaft speed is the same, the effective capacity of the feeding trough 411 is controlled by the stop part 43. The feeding part 41 is driven by the motor to rotate. The acidic or alkaline substances entering the mixing tank 1 along the feeding trough 411 are neutralized and the acidity or alkalinity is adjusted by the action of the stirring rod.

[0035] The motor shaft is connected to the feeding component 41. The position of the feeding component 41 is adjusted by moving the motor, thereby determining the effective capacity of the feeding trough 411 and performing quantitative feeding.

[0036] In general, the fixing member 5 includes a connecting rod 51, which is threadedly connected to the slide plate 442, and has a handle and a rubber block 52 at each end, which can press against the guide rod 441.

[0037] Finally, the bottom end of the connecting rod 51 is provided with an annular groove 511, and the other end of the rubber abutment 52 is provided with a circular groove. The circular groove extends from the opening side toward the axis to form an annular portion 521, and the annular portion 521 engages with the annular groove 511.

[0038] It is worth mentioning that a scale can be provided on the top surface of the box cover 11 or the periphery of the guide rod 441, and the length of the unloading part 41 can be determined by the indication between the sliding plate 442 and the scale.

[0039] Furthermore, the rubber block 52 abuts against the guide rod 441 to fix the slide plate 442, and by utilizing its own deformable characteristics, it engages with the annular part 521 and the annular groove 511 to achieve a detachable connection between the connecting rod 51 and the rubber block 52, preventing the rubber block 52 from aging and becoming inconvenient to replace.

[0040] Of course, the slide plate 442 is threadedly connected to the connecting rod 51 through a threaded hole, which passes through the slide plate 442 so that the rubber block 52 can abut against the guide rod 441.

[0041] Working method: During operation, fertilizer raw materials are transported to the mixing tank 1 through the feed pipe, and then acidic and alkaline substances are placed in a pair of material tanks 3 respectively. The corresponding acidic and alkaline substances are selected for neutralization and adjustment according to the acidity and alkalinity of the fertilizer raw materials.

[0042] The length of the feeding part 41, i.e. the effective capacity of the feeding trough 411, is adjusted by the amount of acidic or alkaline substances to be injected. The connecting rod 51 is twisted to make the rubber block 52 rise. The position of the motor is adjusted by moving the sliding plate 442. Of course, the motor will move the feeding part 41 together.

[0043] After the position is determined, the connecting rod 51 is reversed so that the rubber block 52 presses against the guide rod 441 to fix the feeding part 41. The motor then drives the feeding part 41 to rotate. The feeding part 41 feeds the acid and alkaline substances quantitatively through the feeding trough 411 and then stirs them with the stirring rod.

[0044] Finally, the connecting rod 51 is disassembled, and the rubber abutment 52 is replaced by engaging the annular part 521 with the annular groove 511.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
