Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, specifically to a soil microbial agent quantitative trench application positioning device. Background Technology

[0002] In agricultural production and soil remediation, the application of soil microbial agents plays a crucial role in improving soil structure and promoting crop growth. Currently, in the process of applying soil microbial agents in trenches, some areas still use manual spreading, mixing solid agents with well-rotted organic fertilizer, fine soil, and other materials in a certain proportion before applying them into the trenches.

[0003] However, manual application has significant drawbacks. Lacking a precise quantitative control mechanism, operators rely solely on experience, making it difficult to guarantee consistent and accurate application rates each time. For example, in practice, variations in hand strength, application distance, and angle can easily lead to uneven distribution of the microbial agent in the soil. In some areas, excessive application wastes resources and may negatively impact the soil ecosystem; while in other areas, insufficient application fails to fully realize the soil microbial agent's role in improving soil and promoting crop growth, resulting in abnormal crop growth and significantly reduced soil remediation effectiveness. Therefore, this invention provides a quantitative trench application device for soil microbial agents to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a soil microbial agent quantitative trench application locator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A soil microbial agent quantitative trench application positioning device includes a frame and a handle mounted on the free end of the frame. The frame is equipped with wheels for moving the frame. The frame is equipped with a swingable storage tank for holding a mixture of soil microbial agents. A servo motor is fixedly mounted on the bottom of the storage tank via a motor mounting bracket. The output axis of the servo motor extends upward into the interior of the storage tank. The storage tank is equipped with a discharge mechanism that works with the servo motor to quantitatively discharge the mixture of soil microbial agents inside the storage tank. The interior of the storage tank is equipped with a mixing mechanism that can stir the mixture of soil microbial agents inside the storage tank.

[0007] As a further embodiment of this utility model, the discharge mechanism includes an auxiliary cavity, a rotating block, a first guide hole, a storage hole, and a second guide hole. The lower end of the storage barrel has an auxiliary cavity. The rotating block is movably engaged inside the auxiliary cavity. The output shaft of the servo motor passes through the interior of the auxiliary cavity. The rotating block is fixedly sleeved on the output shaft of the servo motor. The bottom surface of the storage barrel has a first guide hole corresponding to the position of the rotating block. The lower wall surface of the storage barrel has a second guide hole corresponding to the position of the rotating block. Both the first guide hole and the second guide hole are connected to the hollow area inside the rotating block. The rotating block has a storage hole.

[0008] As a further embodiment of this utility model, the first guide hole and the second guide hole are opened in a mirror image offset, and the center of the first guide hole, the storage hole, and the second guide hole are at the same horizontal distance from the center point on the rotating block.

[0009] As a further embodiment of this utility model, the mixing mechanism includes a linkage column and a spiral blade. The linkage column is provided inside the storage tank, and the spiral blade is fixedly connected to the outer wall of the linkage column. The lower wall of the linkage column is fixedly connected to the top surface of the output shaft of the servo motor.

[0010] As a further embodiment of this utility model, the outer wall of the storage bin is symmetrically and fixedly connected to two connecting columns, and the side wall of the two connecting columns that is far apart from each other is movably connected to the adjacent side wall of the frame through bearings.

[0011] As a further embodiment of this utility model, the storage tank is in the form of a combination of a hollow cylindrical body and a hollow conical body, with a cylindrical cavity at the top and a frustum-shaped structure at the bottom.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through its structural design of a storage hopper, auxiliary cavity, rotating block, first guide hole, storage hole, second guide hole, and servo motor, utilizes the servo motor to drive the rotating block to rotate within the auxiliary cavity. The storage hole, with its fixed volume, allows for the quantitative discharge of material through the second guide hole. This solves the problems of existing manual application of soil microbial inoculant mixtures, such as difficulty in accurately controlling the application rate, leading to imbalanced inoculant distribution, abnormal crop growth, poor soil remediation effects, resource waste, and ecological risks. Compared to manual operation and some traditional equipment, it significantly improves the accuracy of fertilization.

[0014] 2. This utility model is equipped with a distribution plate connected to the lower wall of the storage hopper via a fixing rod. When the material is discharged from the second guide hole, it collides and disperses with the frustum-shaped distribution plate. This solves the problem that existing materials tend to accumulate when placed in trenches, preventing the microbial agent from fully and evenly contacting the soil and crop roots, thus reducing the utilization rate of the agent. It ensures the uniform distribution of materials in the trench, enhancing soil improvement and crop growth effects.

[0015] 3. This utility model utilizes a servo motor to drive the linkage column and spiral blades to rotate, simultaneously discharging a quantitative amount of material and stirring and mixing the materials in the storage bin. This solves the problem of difficulty in ensuring uniformity when mixing multiple materials, which affects soil remediation and crop growth. It ensures that the mixture applied to the soil has consistent composition and improves the quality of material mixing.

[0016] 4. This utility model employs a storage hopper that is movably connected to the frame via a connecting column. Combined with a lower motor mounting bracket and a servo motor as counterweights, this structure allows the equipment to maintain a self-righting effect under gravity, keeping the lower part perpendicular to the ground. This solves the problem of existing fertilizer application equipment easily tilting when moving on uneven ground, leading to deviations in material placement and quantity. It improves the applicability and stability of the equipment, and reduces the operational difficulty and workload for operators. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 In this embodiment of the invention, the soil microbial agent quantitative trench application positioning device includes a frame 1 and a handle 2 mounted on the free end of the frame 1. The handle 2 on the frame 1 increases the frictional resistance between the device and the user's hand during use, making it easier for the operator to move the device. Wheels 16 are mounted on the frame 1 to move it, ensuring that the frame 1 can move under external force. The frame 1 also has a swingable storage container for holding the soil microbial agent mixture. The bottom of the storage tank 3 is fixedly mounted with a servo motor 6 via a motor mounting bracket 5. The motor mounting bracket 5 has a U-shaped structure and is fixedly connected to the lower wall of the storage tank 3. The output shaft of the servo motor 6 corresponds vertically to the center point of the storage tank 3. The output shaft of the servo motor 6 extends upward into the interior of the storage tank 3. The storage tank 3 is equipped with a discharge mechanism that works with the servo motor 6 to quantitatively discharge the soil microbial agent mixture inside the storage tank 3. The interior of the storage tank 3 is equipped with a mixing mechanism that can stir the soil microbial agent mixture inside the storage tank 3.

[0025] The discharge mechanism includes an auxiliary cavity 7, a rotating block 8, a first guide hole 9, a storage hole 10, and a second guide hole 11. The lower end of the storage hopper 3 has an auxiliary cavity 7. A rotating block 8, which is disc-shaped, is movably engaged within the auxiliary cavity 7. The output shaft of the servo motor 6 passes through the interior of the auxiliary cavity 7. The rotating block 8 is fixedly sleeved on the output shaft of the servo motor 6, with the center of the rotating block 8 corresponding to the center point of the output shaft of the servo motor 6. The servo motor 6 can drive the rotating block 8 to rotate... The auxiliary cavity 7 rotates inside. The bottom surface of the storage barrel 3 is provided with a first guide hole 9 corresponding to the position of the rotating block 8. The lower wall surface of the storage barrel 3 is provided with a second guide hole 11 corresponding to the position of the rotating block 8. The first guide hole 9 and the second guide hole 11 are both cylindrical through holes of the same shape and size. The first guide hole 9 and the second guide hole 11 are both connected to the hollow area inside the rotating block 8. The rotating block 8 is provided with a storage hole 10. The storage hole 10 is a cylindrical through hole with an inverted trapezoidal cross section, as shown in the storage barrel 3.

[0026] When in use, when the storage hole 10 on the rotating block 8 is vertically aligned with the first guide hole 9, the material inside the storage bucket 3 will fall into the storage hole 10 through the first guide hole 9. Since the rotating block 8 is inside the auxiliary cavity 7, the material will be temporarily stored inside the storage hole 10 and move with the rotation of the rotating block 8 until the storage hole 10 is vertically aligned with the second guide hole 11. Then the material inside the storage hole 10 can be discharged through the second guide hole 11. Since the storage hole 10 can only store a fixed amount of material, the effect of discharging a fixed amount of material through the second guide hole 11 each time can be achieved.

[0027] The first guide hole 9 and the second guide hole 11 are mirror images of each other and are offset. The center of the first guide hole 9, the storage hole 10, and the second guide hole 11 are at the same horizontal distance from the center point of the rotating block 8. Therefore, when the servo motor 6 drives the rotating block 8 to rotate inside the auxiliary cavity 7, the storage hole 10 will continuously pass alternately through the first guide hole 9 and the second guide hole 11 on the storage bucket 3.

[0028] The lower wall of the storage bin 3 is fixedly connected to the material distribution plate 13 at the position corresponding to the storage hole 10 by two fixing rods 12. The upper wall of the two fixing rods 12 is fixedly connected to the lower wall of the storage bin 3 at the corresponding point. The material distribution plate 13 has a frustum-shaped structure.

[0029] When the soil microbial agent mixture inside the storage hole 10 is discharged through the second guide hole 11 during use, the soil microbial agent mixture comes into contact with and collides with the distribution plate 13 during the falling process. The impact force generated by the collision will disperse the soil microbial agent mixture, thereby avoiding the problem of material piling up when the soil microbial agent mixture is put into the trench.

[0030] The mixing mechanism includes a linkage column 14 and a spiral blade 15. The linkage column 14 is installed inside the storage tank 3. The spiral blade 15 is fixedly connected to the outer wall of the linkage column 14. The lower wall of the linkage column 14 is fixedly connected to the top surface of the output shaft of the servo motor 6.

[0031] The outer wall of the storage bin 3 is symmetrically and fixedly connected to two connecting columns 4. The side wall of the two connecting columns 4 that is far apart from each other is movably connected to the side wall of the adjacent side wall of the frame 1 through bearings.

[0032] Since the storage bin 3 is movably connected to the frame 1 through two connecting columns 4, and the servo motor 6 is fixedly connected to the bottom of the storage bin 3 through the motor mounting bracket 5, the motor mounting bracket 5 and the servo motor 6 can play the role of counterweight. When in use, they can imitate the effect of a roly-poly toy under the action of gravity, so that the lower part of the device always remains perpendicular to the ground, thereby ensuring the normal feeding and delivery of materials.

[0033] The storage hopper 3 is a combination of a hollow cylindrical body and a hollow conical body. Its upper part is a cylindrical cavity, and its lower part is connected to a frustum-shaped structure. When in use, the cylindrical part of the storage hopper 3 provides a regular accommodating area, while the conical part facilitates the collection and guidance of materials inside the storage hopper 3.

[0034] The working principle of this utility model is as follows:

[0035] In use, this invention involves first placing the required soil microbial inoculant mixture into the storage tank 3. Then, a worker moves the tank 1 inside the trench using a pusher (2). During this process, a servo motor 6 is activated, driving a rotating block 8 to rotate within the auxiliary cavity 7. When the storage hole 10 on the rotating block 8 aligns vertically with the first guide hole 9, the material inside the storage tank 3 falls into the storage hole 10 through the first guide hole 9. Similarly, when the storage hole 10 aligns vertically with the second guide hole 11, the material inside the storage hole 10 is discharged through the second guide hole 11. Since the storage hole 10 can only hold a fixed amount of material, this method achieves the goal of discharging a fixed amount of material through the second guide hole 11 each time, thus completing the fertilization process inside the trench. This avoids the problems of uneven distribution of inoculants, abnormal crop growth, poor soil remediation, resource waste, and ecological risks associated with manual application.

[0036] When the soil microbial agent mixture inside the storage hole 10 is discharged through the second guide hole 11 during use, the soil microbial agent mixture comes into contact with and collides with the distribution plate 13 during the falling process. The impact force generated by the collision will disperse the soil microbial agent mixture, thereby avoiding the problem of material piling up when the soil microbial agent mixture is put into the trench.

[0037] When using the product, the solid microbial agent needs to be mixed with well-rotted organic fertilizer and fine soil in a certain proportion. In cases where the amount of microbial agent is small, it can be diluted with fine sand or vermiculite before application. Therefore, when the servo motor 6 drives the discharging mechanism to quantitatively dispense the soil microbial agent mixture, the servo motor 6 can also drive the linkage column 14 to rotate. This, in turn, uses the spiral blades 15 on the linkage column 14 to stir and mix the material inside the storage tank 3, thereby improving the mixing effect of multiple materials.

[0038] 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.
