Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fertilizing device for flue-cured tobacco production, in particular to a fertilizing device for flue-cured tobacco production. BACKGROUND

[0002] Flue-cured tobacco is an important economic crop, and its yield and quality are directly affected by field management measures, among which scientific fertilization is one of the key links. The demand for nutrients such as nitrogen, phosphorus and potassium in the growth cycle of flue-cured tobacco has a specific regularity, and the uniformity and timeliness of fertilizers are required. The traditional flue-cured tobacco fertilization method mainly relies on manual operation, which has the problems of high labor intensity, uneven fertilization, low efficiency and the like, and is difficult to meet the needs of modern and large-scale flue-cured tobacco planting. At present, in the production of flue-cured tobacco, the application of solid fertilizers (such as compound fertilizer and granular fertilizer) and liquid fertilizers (such as water-soluble fertilizer and foliar fertilizer) often needs to be carried out separately, and there is a lack of integrated equipment that can simultaneously process two forms of fertilizers. For solid fertilizers, common fertilizing tools are mostly simple spreading equipment, which has inaccurate control of discharging and is prone to uneven fertilization, resulting in over-fertilization or missed fertilization, which affects the uniformity of tobacco plants. For liquid fertilizers, backpack sprayers or simple irrigation devices are often used, which have problems such as uneven mixing, unstable spraying pressure, and easy clogging of nozzles, and the labor intensity of operators is high and the work efficiency is low. In addition, the existing fertilizing device also has deficiencies in adaptability. Flue-cured tobacco planting often adopts ridge mode, and at different growth stages, there are different requirements for the distribution range of fertilizers around the plants. For example, in the early growth stage, the fertilizer is expected to be relatively concentrated, while in the middle and late stages, a wider spreading range is expected to facilitate root absorption. Most existing equipment lacks convenient and effective spreading range adjustment function, and cannot flexibly change the coverage range of fertilizers according to actual needs, affecting the accuracy of fertilization. SUMMARY

[0003] In view of the deficiencies of the prior art, the present application provides a fertilizing device for flue-cured tobacco production, which solves the problem that in the production of flue-cured tobacco, the application of solid fertilizers (such as compound fertilizer and granular fertilizer) and liquid fertilizers (such as water-soluble fertilizer and foliar fertilizer) often needs to be carried out separately, and there is a lack of integrated equipment that can simultaneously process two forms of fertilizers. For solid fertilizers, common fertilizing tools are mostly simple spreading equipment, which has inaccurate control of discharging and is prone to uneven fertilization, resulting in over-fertilization or missed fertilization, which affects the uniformity of tobacco plants. For liquid fertilizers, backpack sprayers or simple irrigation devices are often used, which have problems such as uneven mixing, unstable spraying pressure, and easy clogging of nozzles, and the labor intensity of operators is high and the work efficiency is low. In addition, existing fertilization devices are not adaptable enough. Flue-cured tobacco is often planted in a ridge-planting pattern, and the distribution range of fertilizer around the plant varies at different growth stages. For example, in the early stage of growth, it is desirable for the fertilizer to be relatively concentrated, while in the middle and later stages, a wider diffusion range is desired to facilitate root absorption. Most existing equipment lacks convenient and effective functions for adjusting the spreading range, and cannot flexibly change the fertilizer coverage range according to actual needs, which affects the technical problem of fertilization accuracy.

A plurality of spreading plates are fixedly installed on the shaft and located inside an arc-shaped plate. A pair of cylinders are fixedly installed at both ends of the arc-shaped plate. A column is rotatably installed inside the cylinder, and a baffle plate is fixedly installed on the side wall of the column.

[0007] Preferably, a first gear is fixedly installed on the upper end of the column, an insertion port is opened on the side wall of the cover, a tooth groove is opened on the inner wall of the cover, the cover is inserted into the first gear through the tooth groove, and the cover is inserted into the arc plate through the insertion port.

[0008] Preferably, the water inlet pipe passes through the connecting plate.

[0009] Preferably, the L-shaped plate has a pair of through holes, a U-shaped rod is inserted between the through holes, a pressure plate is fixedly installed between the two ends of the U-shaped rod, the L-shaped plate has a threaded hole between the pair of through holes, a bolt is screwed into the threaded hole, the bolt is rotatably installed on the side wall of the pressure plate, and the other end of the bolt passes through the U-shaped rod.

[0010] Preferably, a handle is fixedly installed at the other end of the bolt.

[0011] Beneficial effects This invention provides a fertilization device for flue-cured tobacco production, which has the following advantages: This invention innovatively integrates the water tank and material tank into one unit. Driven by a single motor, it can simultaneously complete the mixing and spraying of liquid fertilizer and the conveying and spreading of solid fertilizer. This integrated design breaks the traditional mode in fertilization operations where solid and liquid fertilizers must be applied separately. Operators only need to make one trip in the field to complete the application of both forms of fertilizer at the same time, which greatly reduces the number of operations and equipment investment, and improves the overall efficiency of field fertilization. It is particularly suitable for the synergistic needs of different fertilizers during the flue-cured tobacco growth cycle.

[0012] The mixing assembly employs a unique "planetary gear transmission" structure. When the motor drives the rotating plate to revolve via the shaft, the mixing rod mounted on it also revolves. Simultaneously, because the transmission gear at the upper end of the mixing rod meshes with the fixed gear, the mixing rod is forced to rotate. This combined motion of revolution and rotation creates a strong convection and shear flow field within the water tank, enabling thorough and rapid mixing of liquid fertilizer, water, and any added trace elements. This ensures a uniform solution concentration, effectively preventing solute precipitation. It not only guarantees the accuracy of fertilizer concentration but also avoids pump and nozzle blockage caused by sediment, thus improving system reliability.

[0013] For solid fertilizers, the device is designed with a combination of spiral blade conveying and centrifugal spreading. The spiral blades are located inside the discharge pipe, and their rotation ensures that the granular fertilizer in the material box is pushed downwards stably and continuously, effectively preventing interruptions or uneven feeding caused by material bridging or arching. After the fertilizer falls into the arc-shaped plate, it is struck by the high-speed rotating spreading plate and centrifugally thrown out, achieving wide-area spreading. Compared with gravity natural falling, this method results in a more uniform distribution, which helps to improve the uniformity of fertilizer fertility in tobacco fields.

[0014] A key advantage of this invention is that the spread of solid fertilizer can be flexibly adjusted according to the needs of different growth stages of flue-cured tobacco. By manually rotating the baffles at both ends of the arc-shaped plate, the size of the opening between the baffles and the spreader plate can be changed. When concentrated fertilizer is needed, the baffles are adjusted to a smaller opening; when wide spread is needed, the opening is enlarged. After adjustment, the baffles are reliably locked in the set position by engaging the toothed grooves on the cover with the first gear on the column and inserting them into the arc-shaped plate. This design allows a single device to adapt to the fertilization requirements of the entire growth period of flue-cured tobacco, realizing the variable fertilization concept in precision agriculture.

[0015] The device uses a quick-attachment mechanism consisting of an L-shaped plate, a U-shaped rod, a pressure plate, and bolts. It can be easily and securely installed on the rear basket or frame of common agricultural vehicles such as electric vehicles and tractors. When the bolts are screwed in, they push the pressure plate tightly against the wall of the vehicle bed, forming a stable three-point fixation. This avoids equipment shaking or displacement caused by bumps during operation, ensuring the accuracy of the fertilization path. This design gives the device good mobility and is particularly suitable for fertilization operations in small and medium-sized tobacco fields.

[0016] This device integrates power, mixing, conveying, spreading, spraying and fixing functional modules into a relatively compact structure with a reasonable layout. All moving parts are driven by a single motor, resulting in a simple transmission chain that reduces the failure rate and facilitates maintenance. The umbrella-shaped plate design can not only catch small amounts of material that may fall, but also provide an installation platform for the water pump, making full use of space.

[0030] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0031] Example: As shown in the accompanying drawings, during use, the connecting plate 9 is secured to the rear basket of the electric vehicle via the L-shaped plate 10. Then, the bolt 33 is rotated, and it feeds along the path of the threaded hole, causing the bolt 33 to push the pressure plate 32 to press against the rear basket wall of the electric vehicle, thus fixing the connecting plate 9. Liquid fertilizer is then introduced into the water tank 1 through the inlet hopper, and solid material is introduced into the material box 2 through the feed hopper. The electric vehicle is then driven to the planting area. The angle of the blocking plate 27 is adjusted by rotating it, thereby adjusting the angle of the solid fertilizer application.

The motor 7 is then started, and the drive end of the motor 7 drives the shaft 8 to rotate, thereby causing the spiral blade 22 to rotate. Solid material moves downward along the path of spiral blades 22. Shaft 8 drives the spreading plate 24 to rotate, causing the material to be dispersed in all directions by the spreading plate 24 and blocked by the baffle plate 27. The solid material is spread according to the opening size of the baffle plate 27. Shaft 8 drives the rotating plate 18 to rotate, which in turn causes the stirring rod 19 to revolve around shaft 8. Since the transmission gear 20 is meshed with the fixed gear 17, the stirring rod 19 rotates under the action of the transmission gear 20. The stirring rod 19 drives the stirring plate 21 to rotate, thus making the material in the water tank 1 uniformly mixed. When liquid fertilizer is needed, the water pump 11 is started. The water pump 11 introduces the liquid fertilizer in the water tank 1 into the inlet pipe 12 and then into the outlet pipe 14. The outlet pipe 14 introduces the liquid fertilizer into the conduit 13 and then into the nozzle 15 for liquid fertilization.
