Description

Technical Field

[0001] This utility model relates to the field of tobacco field fertilization technology, and in particular to a tobacco field fertilization device with adjustable depth function. Background Technology

[0002] Tobacco field fertilization refers to the agricultural technique of applying various nutrients in the form of fertilizers to the tobacco field soil in a targeted manner during the tobacco planting process, based on the tobacco's growth and development stage, soil fertility status, and expected yield and quality targets. These fertilizers can be inorganic fertilizers, organic fertilizers, or bio-fertilizers, thereby meeting the growth needs of tobacco.

[0003] The fertilization process in tobacco fields requires the use of appropriate fertilizer applicators. These applicators move around to apply fertilizer to the soil, thereby ensuring that the soil is more suitable for tobacco growth.

[0004] Before planting or in the early stages of transplanting tobacco, base fertilizer needs to be applied. The purpose of base fertilizer is to provide a continuous supply of nutrients for the tobacco throughout its growth period. At this time, it is necessary to dig deeper soil (generally 20-30 cm) and bury organic fertilizer, phosphate fertilizer and other base fertilizers deep in the soil. However, the traditional soil breaking depth is usually fixed. When facing soils with different textures, the soil breaking effect may be poor. Therefore, a tobacco field fertilization device with adjustable depth function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tobacco field fertilization device with adjustable depth, which aims to improve the problem of the relatively fixed soil breaking depth in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable depth tobacco field fertilization device, comprising a box, a storage tank fixedly connected to the inner wall of the box, and an adjustment mechanism provided at the bottom of the box;

[0007] The adjustment mechanism includes a support plate, to which a soil breaker is fixedly connected. A base is fixedly connected to the bottom right side of the housing. A threaded rod is rotatably connected to the inner wall of the base. A guide block is threadedly connected to the outer wall of the threaded rod. A connecting plate is rotatably connected to the bottom of the guide block. A rotating plate and a rotary plate are rotatably connected to the bottom of the base. A connecting plate is fixedly connected to the left end of the rotating plate. A positioning component is provided on the inner wall of the connecting plate. A reset component is provided on the inner wall of the rotating plate.

[0013] The positioning element includes a bolt, the outer wall of which is threadedly connected to the inner wall of the connecting plate, and the outer wall of which is threadedly connected to the inner wall of the rotating plate.

[0014] As a further description of the above technical solution:

[0015] The reset assembly includes a connecting spring, one end of which is fixedly connected to the inner wall of the rotating plate, and the other end of which is fixedly connected to a baffle.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the baffle is slidably connected to the inner wall of the rotating plate.

[0018] As a further description of the above technical solution:

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of an adjustable-depth tobacco field fertilization device, comprising a housing 1, a storage tank 2 fixedly connected to the inner wall of the housing 1, guide wheels at the bottom of the housing 1 for easy movement of the housing 1 as a whole, a handle at the left end for manual movement, and the storage tank 2 for storing fertilizer for fertilization operations (this is prior art and will not be explained in detail here). An adjustment mechanism is provided at the bottom of the housing 1; the adjustment mechanism allows for adjustment of the soil breaking depth, thereby enhancing the overall practicality. The structure includes a support plate 5, with a soil-breaking machine 3 fixedly connected to its bottom end. A small motor is installed at the outer end of the soil-breaking machine 3. When in use, the small motor is started, and its output drives the corresponding soil-breaking wheels to rotate. When the soil-breaking wheels rotate, soil-breaking operations can be performed. One end of the coupling of the soil-breaking machine 3 is connected to the motor output shaft, and the other end is connected to the main shaft of the soil-breaking wheels. The connection method is usually a key connection. There are keyways at the connection points between the motor output shaft and the coupling, and at the connection points between the coupling and the main shaft of the soil-breaking wheels. By using a flat key or a semi-circular key... A key is inserted into the keyway to ensure the relative fixation of the motor output shaft, coupling, and main shaft of the excavator wheel in the circumferential direction, enabling them to rotate synchronously. This is existing technology and will not be explained in detail here. A base 7 is fixedly connected to the bottom right side of the housing 1. The base 7 serves as a connection and support for the adjustment mechanism. A threaded rod 6 is rotatably connected to the inner wall of the base 7, and a guide block 12 is threadedly connected to the outer wall of the threaded rod 6. The rotation of the threaded rod 6 causes the guide block 12 to move, thereby achieving the adjustment purpose. A connecting plate 4 is rotatably connected to the bottom end of the guide block 12. The movement of block 12 causes the connecting plate 4 to rotate. The bottom end of the base 7 is rotatably connected to the rotating plate 8 and the rotating plate 9. When the rotating plate 8 and the rotating plate 9 rotate towards the middle, they can provide a certain degree of protection for the threaded rod 6. The left end of the rotating plate 9 is fixedly connected to the connecting plate 10. The inner wall of the connecting plate 10 is provided with a positioning element, which can fix the connecting plate 10. The inner wall of the rotating plate 9 is provided with a reset component. The reset component can adapt to the guide block 12 in different positions and provide protection for the guide block 12 and its threaded rod 6.

[0033] Reference Figure 1 - Figure 3The top of the support plate 5 is rotatably connected to the bottom of the housing 1. The rotation setting avoids motion interference when the adjustment mechanism is working. The outer wall of the guide block 12 is slidably connected to the inner wall of the base 7. The front and rear ends of the guide block 12 are T-shaped to prevent the guide block 12 from falling off when it moves, and the whole can move horizontally. The bottom of the connecting plate 4 is rotatably connected to the inner side wall of the support plate 5. The rotation of the two avoids motion interference. The positioning component includes bolts 11. The outer wall of the bolt 11 is threadedly connected to the inner wall of the connecting plate 10 and the outer wall of the rotating plate 8. The bolts 11 can fix the rotating plate 8 and the rotating plate 9 to prevent them from rotating. There are three sets of guide blocks 12, and the guide blocks 12 on both sides are slidably connected to the outer arc surface of the cylinder to provide better support for the excavator 3.

[0034] Reference Figure 2 - Figure 4 The reset assembly includes a connecting spring 13. One end of the connecting spring 13 is fixedly connected to the inner wall of the rotating plate 9, and the other end of the connecting spring 13 is fixedly connected to a baffle 14. The outer wall of the baffle 14 is slidably connected to the inner wall of the rotating plate 9. The elasticity of the connecting spring 13 enables the baffle 14 to have a reset function, thereby reducing the amount of dirt entering the interior of the base 7. The rotating plate 8 is also equipped with a connecting spring 13 and a baffle 14. The side of the baffle 14 near the threaded rod 6 contacts the outer wall of the connecting plate 4, and the contact between the two serves as a blocking effect. The baffles 14 between the rotating plate 8 and the rotating plate 9 also contact each other. The top of the side of the baffle 14 near the threaded rod 6 is provided with an arc surface, which facilitates the upward rotation of the rotating plate 8 and the rotating plate 9. There are multiple sets of baffles 14 and connecting springs 13. The two sets of baffles 14 that contact the guide block 12 will move into the rotating plate 8 and the rotating plate 9, while the multiple sets of baffles 14 that do not contact the guide block 12 will pop out and reset due to the elasticity of the connecting spring 13, thus achieving a blocking effect.

[0035] Working principle: When relevant personnel need to perform soil breaking operations on the excavator 3, first rotate bolt 11 to release its restriction on connecting plate 10. Then, flip rotating plate 8 and rotating plate 9 downwards, changing them from a horizontal to a vertical position. Then, the threaded rod 6 can be rotated. When the threaded rod 6 rotates, it causes guide block 12 to move laterally. This lateral movement of guide block 12 causes connecting plate 4 to move, thereby driving the excavator 3 to move vertically. The movement is used to achieve the adjustment purpose. After the adjustment is completed, the rotating plate 8 and the rotating plate 9 are reset from the vertical state to the horizontal state. When the rotating plate 8 and the rotating plate 9 rotate, the arc surface of the baffle 14 will contact and press the top of the connecting plate 4, thereby driving the baffle 14 that is in contact with the top of the connecting plate 4 to move outward. When the rotating plate 8 and the rotating plate 9 are in the horizontal state, the bolt 11 is reset and fixed. At this time, the multiple baffles 14 can reduce the entry of soil into the inner wall of the base 7, thereby reducing the risk of soil adhering to the threaded rod 6.

[0036] 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.
