Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer mixing, and more specifically, to a fertilizer mixing device for agricultural cultivation. Background Art

[0002] As crops grow in the land, they absorb necessary nutrients from the soil. If they are planted continuously without replenishing nutrients, these elements in the soil will be depleted, resulting in decreased crop yields and deterioration in quality. Therefore, agricultural farming requires the use of fertilizers to replenish these consumed nutrients in the soil, maintain soil fertility, and ensure the healthy growth of crops.

[0003] Because different plants have different nutrient requirements at different growth stages, mixing different types of fertilizers can meet the various needs of crops throughout their growth period. In order to improve soil structure, enhance the soil's ability to retain water and fertilizer, ensure that nutrients are more evenly distributed in the soil, facilitate absorption by crop roots, and promote healthy plant growth, powdered bentonite-based fertilizers are mixed with granular fertilizers before use. Powdered bentonite-based fertilizers have good water absorption and expansibility, while granular fertilizers typically contain high concentrations of nutrients, allowing the advantages of both fertilizers to be combined when used. In the prior art, when mixing fertilizers, the two fertilizers are separately placed in a mixing tank, and the mixing of the two fertilizers is completed by stirring the fertilizers with mixing blades.

[0004] However, powdered fertilizer and granular fertilizer have different densities and particle sizes. During transportation, storage or application, the mixed fertilizer is prone to separation, and granular fertilizer is prone to accumulation in the lower layer, resulting in uneven distribution of nutrients in the fertilizer and affecting crop growth and development. Utility Model Content

[0005] The utility model provides a fertilizer mixing device for agricultural cultivation, and aims to solve the problem that, when existing fertilizer mixing devices for agricultural cultivation mix powdered fertilizer and granular fertilizer, due to the difference in density and particle size between the powdered fertilizer and the granular fertilizer, the mixed fertilizer is easily separated during transportation, storage or application, and the granular fertilizer is easily accumulated in the lower layer, resulting in uneven distribution of nutrients in the fertilizer, which affects the growth and development of crops.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a fertilizer mixing device for agricultural cultivation, comprising a mixing tank, a feeding port provided at the top of the mixing tank, a discharge port provided at the bottom of the mixing tank, a delivery pipe fixedly provided in the mixing tank, a mixing mechanism provided in the mixing tank, the mixing mechanism comprising mixing blades, fertilizer enters the mixing tank through the feeding port, the mixing blades rotate to mix the fertilizer, and the fertilizer is discharged through the discharge port;

[0007] A screening mechanism is provided in the conveying pipe, and the screening mechanism includes a material receiving cover, which is slidably provided in the mixing tank, and a plurality of discharge holes are provided on the material receiving cover. A push plate is slidably provided in the mixing tank, and the push plate pushes the material receiving cover to slide in the mixing tank by vertical movement. A plurality of dredging rods are fixedly provided on the push plate, and the dredging rods are adapted to the corresponding discharge holes.

[0008] In a preferred embodiment, the mixing mechanism further comprises a rotary driver, which is fixedly arranged on the top of the mixing tank, a connecting shaft is fixedly arranged on the output shaft of the rotary driver, and the mixing blades are fixedly arranged on the connecting shaft.

[0009] In a preferred embodiment, a crushing blade is fixedly provided on the connecting shaft, and the crushing blade is located between the mixing blade and the material receiving cover. A scraper is also fixedly provided on the connecting shaft, and the scraper is in contact with the inner wall of the mixing tank.

[0010] In a preferred embodiment, the screening mechanism includes a linear drive, which is fixedly arranged on the inner wall of the mixing tank, and the output shaft of the linear drive is fixedly arranged on the push plate.

[0011] In a preferred embodiment, a support base is fixedly provided on the inner wall of the mixing tank, and the support base is located below the material receiving cover, and the support base is used to support the material receiving cover.

[0012] In a preferred embodiment, a plurality of legs are fixedly provided on the mixing tank, and the plurality of legs are arranged at equal intervals on the mixing tank.

[0013] The beneficial effects of the present invention are:

[0014] 1. The utility model sets a delivery pipe in the mixing tank. When the mixing blades mix the fertilizer, an adhesive is added to the fertilizer. The adhesive can increase the viscosity between the powder fertilizer and the granular fertilizer, so that the mixed fertilizer will not separate due to different densities. The nutrients in the fertilizer are evenly distributed, ensuring that the nutrients required for crop growth are sufficient.

[0015] 2. The utility model sets a screening mechanism and drives the receiving cover to move vertically through a linear drive to adjust the space during fertilizer mixing to improve the mixing efficiency of the fertilizer. The crushing blades are used to crush the agglomerated fertilizer before discharging to ensure that the particle size of the fertilizer is uniform when it is discharged, which is beneficial for plants to absorb the nutrients of the fertilizer.

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual Figures 1 to 6 A fertilizer mixing device for agricultural cultivation includes a mixing tank 1, a feeding port 11 is provided at the top of the mixing tank 1, a discharge port 12 is provided at the bottom of the mixing tank 1, a conveying pipe 2 is fixedly provided in the mixing tank 1, a mixing mechanism 3 is provided in the mixing tank 1, and the mixing mechanism 3 includes mixing blades 32. Fertilizer enters the mixing tank 1 through the feeding port 11, and the mixing blades 32 mix the fertilizer by rotating, and the fertilizer is discharged through the discharge port 12;

[0025] A screening mechanism 4 is provided in the conveying pipe 2, and the screening mechanism 4 includes a material receiving cover 41, which is slidably provided in the mixing tank 1, and a plurality of discharge holes are provided on the material receiving cover 41. A push plate 43 is slidably provided in the mixing tank 1, and the push plate 43 pushes the material receiving cover 41 to slide in the mixing tank 1 by vertical movement. A plurality of dredging rods 44 are fixedly provided on the push plate 43, and the dredging rods 44 are adapted to the corresponding discharge holes.

[0026] It should be noted that the conveying pipe 2 is fixedly connected to an auxiliary pipe, and the end of the auxiliary pipe away from the conveying pipe 2 is fixedly connected to a water pump, and the feed end of the water pump is fixedly connected to a storage box, and the storage box stores adhesives. The adhesives include but are not limited to natural polymers of starch, cellulose and its derivatives, synthetic polymers such as polyvinyl alcohol PVA, polyacrylates, or inorganic adhesives such as silicates and phosphates. The adhesives are added during the process of mixing fertilizers. The adhesives are used to improve the physical properties of the fertilizer particles, such as enhancing the hardness of the particles, preventing wear and separation between the particles, thereby ensuring the stability and uniformity of the fertilizer during transportation, storage and application.

[0027] The specific implementation scenario is as follows: the default position of the discharge hole is located in the discharge hole to seal the discharge hole, and the powder fertilizer and the granular fertilizer are added to the mixing tank 1 through the feed port 11, and then the feed port 11 is closed, and then the mixing blade 32 is driven to rotate in the mixing tank 1. The rotation of the mixing blade 32 mixes the fertilizer. In the process of fertilizer mixing, an adhesive is added to the mixing tank 1 through the conveying pipe 2. By adding an adhesive to mix the fertilizer, the viscosity between the powder fertilizer and the granular fertilizer can be increased. When the fertilizer is mixed, the dredging rod 44 is driven to move out of the discharge hole, and the fertilizer can be discharged through the discharge port 12 through the discharge hole. Compared with the powder fertilizer and granular fertilizer in the prior art, adding an adhesive when mixing powder fertilizer and granular fertilizer can avoid separation of the fertilizer during transportation, storage and application, ensure that the nutrients in the fertilizer are evenly distributed, and provide sufficient nutrients for crop growth.

[0028] Refer to the instruction manual Figure 2 In order to improve the mixing efficiency of the mixing blades 32 when mixing fertilizers, the mixing mechanism 3 further includes a rotation driver 31, which is fixedly arranged on the top of the mixing tank 1. A connecting shaft 311 is fixedly arranged on the output shaft of the rotation driver 31, and the mixing blades 32 are fixedly arranged on the connecting shaft 311.

[0029] It should be noted that the rotation driver 31 is configured as a motor, the motor is fixedly mounted on the mixing tank 1 , and the connecting shaft 311 is fixedly mounted on the output shaft of the motor.

[0030] It should also be noted that by starting the rotary driver 31, the rotation of the output shaft of the rotary driver 31 drives the connecting shaft 311 to rotate, and the rotation of the connecting shaft 311 drives the mixing blades 32 to perform circular motion. The effect of efficient mixing of fertilizers can also be achieved by changing the rotation direction and speed of the rotary driver 31.

[0031] Refer to the instruction manual Figures 2 to 6Adding an adhesive when mixing powdered fertilizer with granular fertilizer can prevent the powdered fertilizer and granular fertilizer from separating due to density and mass. However, after adding the adhesive, the mixed fertilizer has a certain viscosity, and the fertilizer easily sticks to the inner wall of the mixing tank 1 and is difficult to discharge. After mixing, the fertilizer mixed with the adhesive has a certain viscosity and easily clumps, resulting in uneven size distribution of the mixed fertilizer. To avoid the above problem, specifically, a crushing blade 34 is fixedly provided on the connecting shaft 311. The crushing blade 34 is located between the mixing blade 32 and the material receiving cover 41. The connecting shaft 311 is also fixedly provided with a scraper plate 33, and the scraper plate 33 is in contact with the inner wall of the mixing tank 1. The screening mechanism 4 includes a linear drive 42, which is fixedly provided on the inner wall of the mixing tank 1. The output shaft of the linear drive 42 is fixedly provided with a push plate 43. A support base 13 is fixedly provided on the inner wall of the mixing tank 1. The support base 13 is located below the material receiving cover 41 and is used to support the material receiving cover 41.

[0032] It should be noted that the linear drive 42 is configured as a cylinder, and the output shaft of the cylinder is fixed to the push plate 43 .

[0033] It should also be noted that the initial state of the dredging rod 44 is located in the discharge hole, and the rotary driver 31 is started to mix the fertilizer in the mixing tank 1. When the fertilizer in the mixing tank 1 is mixed, the linear driver 42 is started, and the movement of the output shaft of the linear driver 42 drives the push plate 43 to move upward. During the upward movement of the push plate 43, the material receiving cover 41 is pushed upward. During the upward movement, the material receiving cover 41 changes the space for the mixed fertilizer in the mixing tank 1, which can improve the mixing effect of the fertilizer. The rotation of the connecting shaft 311 drives the scraper plate 33 to rotate, and the scraper plate 33 is in contact with the inner wall of the mixing tank 1. When the scraper plate 33 rotates During the mixing process, the fertilizer stuck on the inner wall of the mixing tank 1 can be scraped off, and a crushing blade 34 is provided on the connecting shaft 311. The crushing blade 34 can further improve the mixing effect of the fertilizer and break up the lumped fertilizer. Then, the push plate 43 is driven downward by the output shaft of the linear drive 42, and the material receiving cover 41 will also move downward under the action of gravity. As the push plate 43 continues to move downward, the support seat 13 supports the material receiving cover 41, and the push plate 43 moves downward again and moves out of the discharge hole. The fertilizer mixed in the mixing tank 1 and with uniform particle size falls through the discharge hole, and finally the fertilizer is discharged through the discharge port 12.

[0034] Refer to the instruction manual Figures 2 to 6 A plurality of legs are fixedly provided on the mixing tank 1 , and the plurality of legs are arranged on the mixing tank 1 at equal intervals.

[0035] It should be noted that the legs can provide stable support for the mixing tank 1 .

[0036] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
