Description

Technical Field

[0001] This utility model belongs to the field of bio-fertilizer application technology, specifically relating to a portable bio-fertilizer application device with a built-in microbial agent pack. Background Technology

[0002] Currently, the application of bio-fertilizers mainly relies on traditional fertilizer applicators, whose core function is "transportation and spreading," while the "bioactive" aspect is usually neglected or simply treated. For powdered or granular bio-fertilizers, hand-cranked spreaders, backpack blower spreaders, or organic fertilizer spreaders paired with tractors are typically used for application. The fertilizer falls from the hopper by gravity and is evenly spread to the field through rotating discs, centrifugal spreaders, or screw conveyors. The microbial agent is pre-mixed into the fertilizer before application.

[0003] However, the core of bio-fertilizers is "live" microorganisms. Traditional premixing methods (mixing the microbial agent into the carrier on a large scale in advance) suffer from problems such as decreased microbial activity during storage and short shelf life. Furthermore, long-distance transportation and improper storage can accelerate their inactivation. In addition, when using traditional bio-fertilizer application devices, farmers need to carry both fertilizer and microbial agent materials and carry out multiple processes such as weighing, mixing, and stirring in the field, which is time-consuming and labor-intensive. Moreover, existing equipment only completes the "application" action and cannot record data such as fertilizer application amount, mixing ratio, and application area, which is not conducive to precision agricultural management and agricultural record keeping.

[0004] Therefore, there is an urgent need to design a portable bio-fertilizer application device with a built-in microbial agent pack to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a portable bio-fertilizer application device with a built-in microbial agent pack to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable bio-fertilizer application device with a built-in microbial agent pack, comprising: The shell contains a main fertilizer storage compartment and a microbial agent packaging compartment. The mixing mechanism includes a mixing chamber located at the bottom of the shell. The mixing chamber is connected to the main fertilizer storage chamber and the microbial agent packaging chamber via connecting pipes. The mixing chamber is equipped with a stirrer inside. The application mechanism includes a fertilizer applicator located on one side of the mixing chamber, a handheld spray bar on one side of the fertilizer applicator, a valve and a flow meter on the handheld spray bar, and an application head at one end of the handheld spray bar.

[0007] Furthermore, it also includes a fixing mechanism, which includes a roller, a rotary motor, and an electric telescopic rod. The roller is located at the top port of the agent pack compartment, and several agent packs are wound on the roller. The output shaft of the rotary motor is keyed to one end of the roller. The electric telescopic rod is fixed to the inner side of the agent pack compartment and is movably connected to the other end of the roller.

[0008] Furthermore, it also includes a release mechanism, which is located directly below the fixing mechanism. The release mechanism includes a corresponding baffle and an electric telescopic rod II. One side of the baffle is provided with several slots, and one end of the electric telescopic rod II is provided with a needle that matches the slot.

[0009] Furthermore, it also includes a control mechanism, which includes a control box mounted on the handheld spray bar. The top of the control box has a start switch and a speed control knob, and the inside of the control box contains a controller that is electrically connected to each electrical appliance.

[0010] Furthermore, the shell is made of engineering plastic, a carrying strap is fixed to one side of the shell, a feeding port is provided on the top of the main fertilizer storage bin, and a partition plate is provided inside the microbial agent pack bin along the horizontal direction, with several through holes on the partition plate.

[0011] Furthermore, a stirring motor is provided on the outer side of the mixing chamber, and the stirring motor is connected to the stirrer in a driving connection.

[0012] Furthermore, the fertilizer applicator is a pneumatic spraying machine, with its feed inlet connected to the discharge outlet of the mixer, and its airflow pipe connected to one end of the handheld spray bar.

[0013] The technical effects and advantages of this utility model are as follows: This portable bio-fertilizer application device with a built-in microbial agent pack is advanced in design, compact in structure, and easy to use. The built-in microbial agent pack effectively solves the problems of decreased microbial activity and short shelf life in traditional premixing methods, avoiding the impact of long-distance transportation and improper storage on microbial activity. Through the cooperation of the fixing and releasing mechanisms, the microbial agent pack can be precisely released into the mixing chamber to mix with the fertilizer in the main fertilizer storage chamber, eliminating the need for farmers to perform tedious weighing, mixing, and stirring processes in the field, greatly improving fertilization efficiency. The control mechanism makes the device more convenient and intelligent to operate. Operators can flexibly control the device's operation and fertilization speed through the start switch and speed control knob on the control box. Simultaneously, the controller can precisely control each electrical component to ensure stable operation. The valve and flow meter on the handheld spray bar can easily control the amount of fertilizer applied and record fertilization data, which is beneficial for precision agriculture management and agricultural record keeping. Furthermore, the shell is made of engineering plastic, making it lightweight and easy to carry. The shoulder strap design further enhances the device's portability, allowing farmers to easily carry it for fertilization operations. The use of pneumatic seeders allows fertilizer to be sprayed evenly into the field, improving the uniformity and effectiveness of fertilization. The external mixing motor in the mixing chamber drives the agitator to thoroughly mix the fertilizer and microbial agents, ensuring complete mixing and improving the quality and effectiveness of the bio-fertilizer.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] This utility model provides, for example Figure 1-2 The portable bio-fertilizer application device shown includes a built-in microbial agent pack. The shell 100 has a main fertilizer storage compartment 101 and a microbial agent packaging compartment 102 inside the shell 100. The mixing mechanism 200 includes a mixing chamber 201 located at the bottom of the housing 100. The mixing chamber 201 is connected to the main fertilizer storage chamber 101 and the microbial agent packaging chamber 102 via connecting pipes. The mixing chamber 201 is equipped with a stirrer 202. The connecting pipe connected to the main fertilizer storage chamber 101 is equipped with a gate valve for controlling the opening and closing of the mixing chamber. The bottom of the mixing chamber 201 is equipped with a weighing sensor for weighing the bio-fertilizer. When the bio-fertilizer entering the mixing chamber 201 reaches the set weight, the gate valve automatically closes. When the bio-fertilizer entering the mixing chamber 201 is lower than the set weight, the gate valve automatically opens. The application mechanism 300 includes a fertilizer applicator 301 located on one side of the mixing chamber 201. A handheld spray bar 302 is provided on one side of the fertilizer applicator 301. A valve 303 and a flow meter 304 are provided on the handheld spray bar 302. An application head 305 is provided at one end of the handheld spray bar 302. The application head 305 can be selected as a straight-through granular fertilizer pipe for deep application to the root zone or a fan-shaped hood for wide-area application, depending on the actual use requirements.

[0019] For example, see Figure 1 As shown, it also includes a fixing mechanism 400, which includes a roller 401, a rotary motor 402, and an electric telescopic rod 403. The roller 401 is located at the top port of the inoculant pack 102, and several inoculant packs are wound on the roller 401. The output shaft of the rotary motor 402 is keyed to one end of the roller 401. The electric telescopic rod 403 is fixed to the inner side of the inoculant pack 102 and is movably connected to the other end of the roller 401.

[0020] In this technical solution, the rotary motor 402 drives the roller 401 to rotate, enabling the orderly release of the inoculum packs. The electric telescopic rod 403 serves to assist in supporting and adjusting the position of the roller 401, ensuring that the inoculum packs can fall smoothly to the release mechanism 500. When it is necessary to release the inoculum packs, the rotary motor 402 starts, the roller 401 rotates, and the inoculum packs are transported to one side of the baffle 501. When the inoculum packs are used up, the rotary motor 402 drives the roller 401 to rotate in the opposite direction, winding the used inoculum packs back onto the roller 401. Then, the electric telescopic rod 403 is controlled to retract, making it easy to remove and replace the roller 401.

[0021] For example, see Figure 2 As shown, it also includes a release mechanism 500, which is located directly below the fixing mechanism 400. The release mechanism 500 includes a corresponding baffle 501 and an electric telescopic rod 502. The baffle 501 has several slots 5011 on one side, and the electric telescopic rod 502 has a needle 5021 at one end that matches the slots 5011.

[0022] In this technical solution, when the microbial agent packet reaches one side of the baffle 501, the electric telescopic rod 502 is activated, and the piercing needle 5021 inserts into the slot 5011 to puncture the microbial agent packet, allowing the microbial agent to fall into the mixing chamber 201. This design can precisely control the release quantity and timing of the microbial agent packet, ensuring an accurate mixing ratio between the microbial agent and the fertilizer.

[0023] For example, see Figure 1As shown, it also includes a control mechanism 600, which includes a control box 601 mounted on the handheld spray bar 302. The top of the control box 601 is provided with a start switch 602 and a speed adjustment knob 603. Inside the control box 601 is a controller 604 that is electrically connected to each electrical appliance.

[0024] In this technical solution, the operator can turn the entire device on or off using the start switch 602, while the speed control knob 603 can adjust the working speed of the fertilizer applicator 301 according to different fertilization needs, thereby controlling the amount of fertilizer applied. The controller 604 receives signals from various sensors and precisely controls the electrical components such as the rotary motor 402, the electric telescopic rod 403, the electric telescopic rod 502, the stirring motor 203, and the fertilizer applicator 301, realizing the automated and intelligent operation of the device.

[0025] For example, see Figure 1 As shown, the shell 100 is made of engineering plastic. A shoulder strap 103 is fixed on one side of the shell 100. The top of the main fertilizer storage chamber 101 is provided with a feeding port 1011. The inside of the microbial agent packaging chamber 102 is provided with a partition plate 1021 arranged in the horizontal direction. The partition plate 1021 is provided with several through holes 1022.

[0026] In this technical solution, the engineering plastic material makes the shell 100 lightweight and corrosion resistant, the carrying strap 103 facilitates farmers to carry the device for mobile fertilization, the feeding port 1011 facilitates the addition of fertilizer to the main fertilizer storage bin 101, the partition plate 1021 can separate the inoculant pack from the discharge port at the bottom of the inoculant pack bin 102, preventing the used inoculant pack from accumulating at the discharge port of the inoculant pack bin 102 and affecting the flow of inoculant liquid to the mixing bin 201, and the setting of the through hole 1022 ensures that the inoculant liquid can flow through the partition plate 1021 to the bottom of the inoculant pack bin 102.

[0027] For example, see Figure 1 As shown, a stirring motor 203 is provided on the outer side of the mixing chamber 201, and the stirring motor 203 is connected to the stirrer 202 for transmission.

[0028] In this technical solution, after the stirring motor 203 starts, it drives the agitator 202 to rotate, which fully stirs the fertilizer and microbial agent entering the mixing chamber 201, so that the two are evenly mixed, thereby improving the quality and effect of the bio-fertilizer.

[0029] For example, see Figure 1 As shown, the fertilizer applicator 301 is a pneumatic seeding machine. The feed inlet of the fertilizer applicator 301 is connected to the discharge outlet of the mixer 202, and the airflow pipe of the fertilizer applicator 301 is connected to one end of the handheld spray bar 302.

[0030] In this technical solution, the pneumatic hydroseeder uses high-speed airflow to evenly spray the mixed bio-fertilizer onto the field through the handheld spray bar 302 and the application head 305, ensuring the uniformity and coverage of fertilization and improving fertilization efficiency and effectiveness.

[0031] Working principle: When using this portable bio-fertilizer application device with built-in microbial agent packs, firstly, the pre-prepared fertilizer is added into the main fertilizer storage bin 101 through the feeding port 1011. Then, the roller 401 with the microbial agent pack wrapped around it is installed on the top of the microbial agent pack bin 102. At this time, the operator carries the entire device on his / her back through the shoulder strap 103. Then, the operator turns on the start switch 602 on the control box 601 to start the entire fertilization device into operation. At this time, the gate valve opens, and the bio-fertilizer enters the mixing chamber 201 through the connecting pipe under the action of gravity. At the same time, the rotary motor 402 starts immediately and drives the drum 401 to rotate. The drum 401 conveys the inoculant pack downward to one side of the baffle 501. When the inoculant pack accurately reaches the designated position, the electric telescopic rod 502 begins to extend, pushing the piercing needle 5021 to insert into the slot 5011, quickly piercing the inoculant pack, so that the inoculant liquid falls into the bottom of the inoculant pack chamber 102 and flows into the mixing chamber 201 through the connecting pipe. Subsequently, the stirring motor 203 starts to run, driving the stirrer 202 in the mixing chamber 201 to rotate, fully stirring the continuously entering fertilizer and inoculant, ensuring that the two can be mixed evenly and thoroughly. After the mixture is completed, the bio-fertilizer smoothly enters the fertilizer applicator 301 through the discharge port at the bottom of the stirrer 202. The fertilizer applicator 301 uses high-speed airflow to spray the fertilizer onto the field through the handheld spray bar 302 and the application head 305. In addition, the device has an intelligent data recording function, which can automatically record important data such as the amount of fertilizer applied, the ratio of microbial fertilizer to fertilizer, and the area covered in each operation. This greatly facilitates the implementation of precision agriculture and daily agricultural management. When the microbial agent pack is used up, the rotary motor 402 automatically switches to reverse rotation, driving the roller 401 to wind and collect the used microbial agent pack. Then, the electric telescopic rod 403 retracts, making the roller 401 easier to disassemble, and farmers can quickly replace it with a new microbial agent pack. Throughout the fertilization process, the controller 604 continuously coordinates and precisely controls the various electrical appliances to ensure that the device always operates stably and efficiently. This not only significantly improves the efficiency of fertilization operations but also effectively reduces the labor burden on farmers. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
