Description

Technical Field

[0001] The invention relates to the field of agricultural machinery and equipment, in particular to a sugarcane nitrogen fertilizer application control device. Background Art

[0002] Sugarcane is an important sugar crop in the world and also an important raw material for producing bioenergy such as ethanol. In many tropical and subtropical regions, sugarcane cultivation is an important pillar industry of the local agricultural economy, providing a large amount of raw materials for sugar production, energy and other related industries, and plays a vital role in ensuring sugar supply and promoting the development of energy diversification.

[0003] Nitrogen fertilizer is one of the main nutrients required for sugarcane growth. Adequate nitrogen fertilizer supply can significantly promote the growth of sugarcane plants, including increasing the height and thickness of the stems, increasing the number and area of ​​leaves, and thus increasing the biomass accumulation of sugarcane. It also plays a key regulatory role in the physiological processes of sugarcane such as photosynthesis and protein synthesis, and directly affects the yield and quality of sugarcane. In the early stage of sugarcane growth, an appropriate amount of nitrogen fertilizer helps the rapid growth of seedlings and the development of the root system; during the vigorous growth period, nitrogen fertilizer can maintain the rapid elongation and thickening of sugarcane stems.

[0004] Although some equipment can achieve a certain degree of stirring function by driving the stirring parts to rotate through the motor, and only rely on a single stirring arm or stirring shaft for rotation and stirring, it is often unable to effectively reach and stir the fertilizers at the bottom of the fertilizer pile and in the edge corners, resulting in uneven mixing of the fertilizers in these areas. During the fertilizer mixing process, due to differences in fertilizer particle size, density and other factors, some fertilizers often gradually settle at the bottom of the container, and it is unable to effectively stir the fertilizers deposited at the bottom, making it impossible for the fertilizers deposited at the bottom to interact and mix well with the fertilizers being stirred on the top, ultimately affecting the uniformity of the entire fertilizer mixing.

[0016] Working principle: The driving arm is driven to rotate by the first motor. When the driving arm rotates, the second gear is driven to directly transmit with the first gear through the driving arm, and the first stirring rod and the first stirring blade are driven to rotate on their own. During use, the upper part is stirred. During use, the first stirring rod drives the third gear when it moves. At this time, the third gear drives the second stirring rod to rotate in the opposite direction by directly rotating with the gear ring when it rotates. Therefore, during use, the second stirring rod drives the second stirring blade to rotate and stir at the bottom of the tank. During use, when the upper first stirring blade and the lower second stirring blade rotate, turbulent friction is formed in the middle, thereby further stirring the nitrogen fertilizer when mixing and fusing. The effect of rapid fusion and uniformity is achieved. During use, when the driving arm rotates, the driving arm drives the auger column to rotate inside the lifting tube. Through the gap at the bottom of the lifting tube, the nitrogen fertilizer stirred at the bottom can be lifted to the upper part, so as to further achieve the effect of fusion and pre-mixing. During use, the fertilizer and water can be fully mixed, so as to ensure the consistency and uniformity of the sprayed fertilizer during use, and prevent some part of the fertilizer from being fully mixed, resulting in excessive fertilization of some sugarcane after spraying. The whole can be moved by moving the base, and it can be overlapped with agricultural machinery and equipment when in use. The second motor drives the first steering gear to drive the second steering gear to drive the steering column between the limit block and the support The plate is limited and rotates. During use, the second steering gear drives the steering column to drive the spray shell to adjust the angle. During use, the spray shell can be rotated to unfold and fold the spraying part. When transporting and moving between fields, the floor space can be reduced, so that it can pass through rural roads and narrow roads, further increasing the flexibility of the movement of the device and equipment. When the longitudinal adjustment rod is driven to rotate by the third motor, the longitudinal adjustment rod drives the connecting rod and the connecting plate to drive the spray head to achieve the effect of longitudinal angle adjustment under the limit of the load-bearing plate. During use, the spraying angle can be first adjusted according to the needs of fertilization. The effect is that during use, the worm gear drives the worm wheel to rotate on the inner wall of the protective shell, and when the worm gear drives the adjusting column to rotate, the adjusting column drives the connecting sleeve to slide on the outer wall of the longitudinal adjusting rod. At this time, the connecting sleeve can drive the transverse adjusting rod forward and backward during the movement, so that during use, the transverse adjusting rod drives the connecting plate to drive the spraying head under the limit of the connecting rod to achieve the effect of transverse angle adjustment. During use, the spraying angle can be adjusted to multiple angles according to the needs of fertilization, so that the fertilizer can be better attached to the branches and leaves of sugarcane for absorption, and at the same time, it can avoid the situation that the fertilizer cannot be better attached to the branches and leaves due to the inability to adjust the angle, resulting in a large amount of fertilizer waste.

[0017] The present invention provides a sugarcane nitrogen fertilizer application control device, which has the following beneficial effects: 1. The present invention drives the driving arm to rotate by the first motor, and achieves the first stirring effect during use. When the second gear and the first gear are engaged, the upper part rotates, and the second stirring effect of upper stirring is achieved. When the first stirring rod moves, the third gear is driven to engage with the gear ring to achieve the third stirring effect. When in use, the lifting component can be used to lift the fertilizer deposited on the bottom, further increase the mixing speed and ensure the effect of uniform mixing.

[0018] 2. The present invention drives the first steering gear and the second steering gear to rotate through the second motor, and drives the steering column through the second steering gear to drive the spray shell to unfold and fold under the limit of the limit block and the support plate. During use, it can be folded and unfolded. During use, it can reduce the floor space and improve the flexibility of the device when moving between fields according to the use environment and the size of the road.

[0019] 3. The present invention drives the longitudinal adjustment rod to rotate under the limit of the load-bearing plate through the third motor to achieve the effect of longitudinal adjustment, and drives the worm wheel to rotate inside the protective shell through the worm. When the worm wheel drives the adjustment column and the connecting sleeve to slide on the outer wall of the longitudinal adjustment rod, the connecting sleeve drives the transverse adjustment rod to rotate on the inner wall of the connecting plate. When the connecting plate drives the spray head under the limit of the connecting rod, the transverse adjustment rod drives the connecting plate to drive the spray head under the limit of the connecting rod to achieve the effect of transverse angle adjustment. During use, the spraying angle can be adjusted according to the usage situation, so that the fertilizer can be better attached to the branches and leaves of sugarcane for absorption.
