[0002] Rice plant protection, also known as rice plant conservation, refers to a series of measures taken to prevent and control various biotic (such as pests, pathogens, and weeds) and abiotic (such as drought, floods, and nutrient deficiencies) factors that affect rice growth, in order to ensure healthy rice growth and achieve high and stable yields. Effective plant protection strategies can not only reduce crop losses but also improve rice quality and promote sustainable agricultural development.

[0003] However, in the existing technology, the wheels of traditional rice fertilization devices are fixed, which makes it inconvenient to adjust according to the row spacing of rice. Therefore, during the fertilization process, the wheels are prone to crushing the rice, thereby damaging the rice and affecting its growth. Moreover, most rice fertilization devices are not convenient to adjust the height according to the growth of rice. The low vehicle body makes it easy to crush the rice, causing fertilizer to be spilled on the rice and causing damage. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, such as Figure 1-4 As shown, this utility model provides a rice fertilization device for rice plant protection, comprising: a base plate 1, with two grooves 118 formed on the outer surface of the bottom of the base plate 1, each groove 118 having a bidirectional screw 122 movably embedded inside, one end of each bidirectional screw 122 penetrating through the groove 118, and rectangular sleeves 102 movably fitted onto the outer surface of each of the two bidirectional screws 122, the rectangular sleeves 102 being divided into two groups, the outer surfaces of the two groups of rectangular sleeves 102 having through grooves 103, and adjusting plates 104 movably embedded inside the two groups of rectangular sleeves 102, with limiting blocks 119 fixedly installed on the top of the two groups of adjusting plates 104. The device is embedded inside the through groove 103 and includes: multiple wheels 106, all fixedly installed at the bottom of two sets of adjusting plates 104, with multiple limiting holes 105 on the outer surface of the two sets of adjusting plates 104; multiple limiting pins 116, movably embedded at the lower end of one side of two sets of rectangular sleeves 102, with springs 117 fixedly connected to the outer surface of each of the two sets of limiting pins 116, and the other end of each of the two sets of springs 117 fixedly connected to the outer surface of the rectangular sleeves 102; two pulleys 120, each fixedly installed at one end of two bidirectional screws 122, with belts 121 rotating inside the two pulleys 120; and a protective cover 123, fixedly installed on one side of the base plate 1.

[0032] In this embodiment, the height of the base plate 1 is first adjusted according to the height of the rice. The limiting pin 116 is pulled out from the inside of one of the limiting holes 105, allowing the adjusting plate 104 to be adjusted inside the rectangular sleeve 102. After adjustment to a suitable position, the limiting pin 116, under the elastic force of the spring 117, embeds itself into the limiting hole 105 to limit the adjusting plate 104. The four adjusting plates 104 are adjusted sequentially. Then, the servo motor 101 is turned on to drive one of the bidirectional screws 122 to rotate. The bidirectional screw 122 can drive two rectangular sleeves 102 to move relative to or away from each other, according to... The row spacing of rice planting is adjusted to prevent the wheels 106 from crushing the rice and affecting its growth. Each of the two bidirectional screws 122 has a pulley 120 fixedly installed at one end. The pulley 120 has a belt 121 inside it. The belt 121 and the pulley 120 can drive the other bidirectional screw 122 to rotate. Therefore, the four wheels 106 can be adjusted at the same time. The outer surface of the belt 121 and the pulley 120 is provided with a protective cover 123 to protect them and improve the service life of the belt 121 and the pulley 120.

[0033] Example 2, as Figure 1-4 As shown, a servo motor 101 is fixedly installed on one side of the base plate 1. The output end of the servo motor 101 passes through the slide groove 118 and is fixedly connected to one end of one of the bidirectional screws 122. A storage box 113 is fixedly installed at the top center of the base plate 1. A conveying pipe 114 is fixedly installed at the bottom of the storage box 113. A conveying cylinder 112 is fixedly installed at the center of one side of the base plate 1. The other end of the conveying pipe 114 is connected to the conveying cylinder 112. The internal structure of the conveying cylinder 112 is movable. The feed cylinder 112 is equipped with auger blades 124. A drive motor 115 is fixedly installed on one side of the feed cylinder 112. The output end of the drive motor 115 is fixedly connected to the auger blades 124. A groove 111 is provided at the center of one side of the base plate 1. A baffle plate 107 is fixedly installed at the bottom of one side of the base plate 1. A fixing plate 108 is fixedly installed at the center of the lower end of one side of the baffle plate 107. A stepper motor 109 is fixedly installed on the top of the fixing plate 108. A fertilizer spreading disc 110 is fixedly installed at the output end of the stepper motor 109.

[0034] In this embodiment, after adjustment, fertilizer is placed inside the storage box 113. At the same time, the drive motor 115 and the stepper motor 109 are turned on. The drive motor 115 drives the auger blades 124 to convey the fertilizer sent into the conveying cylinder 112 by the conveying pipe 114 to the other end. Then, it falls into the groove 111 through the discharge port. The groove 111 is inclined, so the fertilizer can slide onto the fertilizer spreading disc 110. The stepper motor 109 drives the fertilizer spreading disc 110 to rotate, so that the fertilizer can be spread out and fertilized on a larger area of ​​rice.

[0035] Working principle: In use, first adjust the height of the base plate 1 according to the height of the rice. Pull the limiting pin 116 out from the inside of one of the limiting holes 105, so that the adjusting plate 104 is adjusted inside the rectangular sleeve 102. After adjusting to the appropriate position, the limiting pin 116 is inserted into the inside of the limiting hole 105 under the elastic force of the spring 117 to limit the adjusting plate 104. Adjust the four adjusting plates 104 in sequence. Then, turn on the servo motor 101 to drive one of the bidirectional screws 122 to rotate. The bidirectional screw 122 can drive the two rectangular sleeves 102 to move relative to each other or in opposite directions, adjusting according to the row spacing of rice planting to prevent the wheel 106 from crushing the rice and affecting its growth. One end of each of the two bidirectional screws 122 is fixedly installed with a pulley 120. The pulley 120 is fitted with a belt 121 inside, which rotates to drive the rice. 121, in conjunction with pulley 120, can drive another bidirectional screw 122 to rotate, thus allowing simultaneous adjustment of all four wheels 106. A protective cover 123 is provided on the outer surface of belt 121 and pulley 120 to protect them and improve their service life. After adjustment, fertilizer is placed inside storage bin 113, and simultaneously the drive motor 115 and stepper motor 109 are turned on. The drive motor 115 drives the auger blades 124 to convey the fertilizer from the conveying pipe 114 into the conveying cylinder 112 to the other end, where it falls through the outlet into the groove 111. The groove 111 is inclined, allowing the fertilizer to slide onto the spreading disc 110. The stepper motor 109 drives the spreading disc 110 to rotate, thus spreading the fertilizer over a wider area for fertilizing the rice.
