Description

Technical Field

[0001] The present application relates to the technical field of fertilizer quantitative extraction, and more specifically, to a fertilizer quantitative mixing device. Background Art

[0002] Fertilization refers to the agricultural technology measure of applying fertilizer to the soil or spraying it on plants to provide the nutrients needed by plants and maintain and improve soil fertility. With the development of modern precision agriculture, precision fertilization has also developed rapidly and will become an important fertilization mode. Some existing fertilization devices are difficult to quantitatively extract and mix multiple fertilizers.

[0003] The document with the prior art publication number CN218107443U provides a fertilizer quantitative mixing device based on the balanced fertilization technology for vegetables. The device can place different fertilizers through the arrangement of the first material trough, the second material trough and the third material trough. The coordinated use of the motor, the rotating shaft and the material control rotating drum can realize the controlled delivery of the fertilizers in the first material trough, the second material trough and the third material trough. Then, through the coordinated use of the delivery pipe and the pump, the fertilizers can be smoothly delivered to the collection box, which is convenient for fertilizing the vegetables. Through the coordinated use of the driving motor and the stirring rod, the fertilizers in the collection box can be fully stirred, thereby preventing insufficient fertilizer mixing, resulting in uneven nutrition of vegetables during fertilization. Through the arrangement of the electromagnetic valve, it is convenient to open the opening for fertilization. The utility model has a simple and reasonable structure, a novel design, and is simple and convenient to operate. It effectively solves the problem that the existing fertilization device is difficult to control the amount of extraction and sufficient mixing of multiple fertilizers, and has high practical value.

[0004] However, the device requires the coordinated use of multiple motors, and the motors need to be powered on before they can be used. Therefore, there are certain limitations in its use, and the overall procurement and subsequent maintenance costs are increased.

[0005] Regarding the above-mentioned related technologies, the inventor believes that the device requires the coordinated use of multiple motors when in use, and the motors need to be powered on before they can be used. Therefore, there are certain limitations in use, and the overall procurement and subsequent maintenance costs are increased.

[0006] In view of this, we propose a fertilizer quantitative mixing device. Utility Model Content

[0033] Reference Figure 1-Figure 6, add different fertilizers into the corresponding troughs, and then push the handrail 104. At this time, the cart 1 is moving and the driving shaft 102 is driven to rotate by the wheels 103. The driving shaft 102 drives the screw conveyor 301 to operate under the transmission action of the transmission mechanism 4. The screw conveyor 301 drives the baffle 302 to rotate. When the baffle 302 blocks the discharge hole 204 during the rotation, it cannot discharge the material. When the discharge hole 204 is placed between the two baffles 302, the fertilizer falls into the screw conveying mechanism 301 under the action of gravity. The screw conveyor 301 rotates counterclockwise, and various fertilizers are mixed in the screw conveyor 301 and finally discharged through the discharge port 1011 to achieve the purpose of fertilization. The cart 1 is pushed at a uniform speed, and the baffle 302 intermittently blocks the discharge hole 204 to achieve the purpose of quantitative discharging and quantitative mixing. The whole does not require motor coordination, the structure is simple, and the procurement and maintenance costs are reduced.

[0034] The material storage box 2 includes a round barrel 202 and a conical barrel 203 which is connected to the round barrel 202 , and a discharge hole 204 is provided at the lower end of the conical barrel 203 .

[0035] Reference Figure 5 The conical barrel 203 is an inverted frustum structure, so that the fertilizer in the trough can be accumulated toward the discharge hole 204 to facilitate discharge.

[0036] The screw conveyor 301 includes a barrel 3011 and a spiral blade 3012 rotatably disposed in the barrel 3011 . The upper end of the output shaft of the spiral blade 3012 is rotatably connected to the conical barrel 203 via a bearing.

The upper end of the cylinder 3011 is fixed to the lower end of the conical bucket 303, and the lower end is fixed to the supporting plate 101.

[0038] The transmission mechanism 4 includes a worm 401 and a worm wheel 402 meshing with the worm 401 . The worm 401 is coaxially fixed to the driving shaft 102 , and the worm wheel 402 is coaxially fixed to the lower end of the output shaft of the spiral blade 3012 .

[0039] Reference Figure 3 When the cart 1 is pushed, the driving shaft 102 drives the worm 401 to rotate, the worm 401 drives the worm wheel 402, and finally the spiral blade 3012 is driven to rotate through the worm wheel 402.

[0040] An inverted conical bucket 303 is fixedly mounted on the lower end of the spiral blade 3012 , and the transmission mechanism 4 is covered below the conical bucket 303 .

[0041] Reference Figure 3When discharging at the discharge port 1011, the conical bucket 303 is used to block the fertilizer from falling into the space between the worm 401 and the worm wheel 402 and causing the fertilizer to get stuck. At the same time, the conical bucket 303 can also guide the falling fertilizer.

[0042] Working principle: different fertilizers are added into the corresponding troughs, and then the handrail 104 is pushed. At this time, the cart 1 is moving, and the wheel 103 drives the driving shaft 102 to rotate, and the driving shaft 102 drives the worm 401 to rotate, and the worm 401 drives the worm wheel 402, and finally the spiral blade 3012 is driven to rotate through the worm wheel 402 to push the cart 1. During the process of the baffle 302 intermittently blocking the discharge hole 204, when the discharge hole 204 is placed between the two baffles 302, the fertilizer falls into the spiral conveying mechanism 301 under the action of gravity, and the spiral conveyor 301 rotates counterclockwise. Multiple fertilizers are mixed in the spiral conveyor 301 and finally discharged through the discharge port 1011. When discharging at the discharge port 1011, the conical bucket 303 is used to block the fertilizer to prevent it from falling into the space between the worm 401 and the worm wheel 402 and causing it to get stuck. At the same time, the conical bucket 303 can also guide the falling fertilizer to spread the material.
