The present device can directly spray fertilizer on both sides of the crops at the same time without moving to the other side of the crops, which can improve the fertilization efficiency of the device and expand the scope of application of the device. At the same time, the hydraulic cylinder can drive the fertilizer box to move up together, thereby increasing the height of the device to prevent the crops from contacting the fertilizer box after growth, thereby affecting fertilization, so that the device can be suitable for crops at different growth stages, further expanding the scope of application of the device.

[0009] 1. When the water-fertilizer integrated self-propelled fertilizing device is in use, the electric door will open and the fertilizer and additives separated by the partition will be discharged into the guide frame together. When the weight measured by the electronic scale decreases to the preset value, the electronic scale will send an electrical signal to the controller. After receiving the electrical signal, the controller will send an electrical signal to the electric door at the corresponding position. When the electric door receives the electrical signal, it will close. After all four electric doors are closed, the automatic proportioning of fertilizer and additives can be completed.

[0010] 2. The water-fertilizer integrated self-propelled fertilizing device drives the preliminary mixing of fertilizers and additives in the guide frame through the rotation of the stirring plate, which can improve the mixing effect of the subsequent fertilizers and additives after contact with water. The reciprocating moving plate allows the mixed fertilizers and additives in the guide frame to intermittently fall into the fertilizer box and mix with the water inside it, which can prevent the fertilizers and additives from falling into the fertilizer box at once and causing accumulation and agglomeration, thereby affecting the mixing effect of the fertilizers and additives with water.

[0011] 3. The self-propelled fertilizing device with integrated water and fertilizer can spray water and fertilizer on both sides of the crops at the same time when the device moves. Since the crops are planted in rows, the general self-propelled fertilizing device will first spray fertilizer on one side of the row of crops, and then move to the other side of the crops to spray fertilizer on them. However, this device can directly spray fertilizer on both sides of the crops at the same time without moving to the other side of the crops, which can improve the fertilization efficiency of the device and expand the scope of application of the device. At the same time, the hydraulic cylinder can drive the fertilizer box to move upward together, thereby increasing the height of the device to prevent the crops from contacting the fertilizer box after growth, thereby affecting fertilization, so that the device can be applied to crops at different growth stages, further expanding the scope of application of the device.

[0012] 4. The water-fertilizer integrated self-propelled fertilizing device can stir the fertilizer and additives that fall into the water through the impeller, thereby improving the mixing effect of the fertilizer and additives. At the same time, the rubber rod contacts the crops when swinging and shakes the crops, so that the water and fertilizer droplets on the surface fall into the soil and are absorbed by the roots of the crops, which can improve the absorption effect of the crops on fertilizers. At the same time, it also prevents the water droplets from staying on the leaves of the crops, which in turn causes part of the water and fertilizer to evaporate under the sunlight, thereby affecting the fertilization effect of the crops. It also prevents the water droplets from focusing the sunlight and causing leaf burns. At the same time, the reciprocating cutter will cut off the top of the crops, making all crops the same height, which can stimulate the development of buds at the bottom or side of the crops, and promote the growth of side branches and tillers. At the same time, pruning can keep the plants in a relatively uniform shape, avoiding uneven nutrient distribution due to excessively tall plants, thereby affecting the overall health and yield of the crops.

[0024] See also Figure 1 - Figure 7On the basis of the above embodiment, in another embodiment of the present invention, the moving mechanism 2 includes a support plate 21, a roller 22, a fixed plate 23 and a motor 24. The support plate 21 is fixedly connected to the bottom of the base 1, the roller 22 is rotatably connected to the surface of the support plate 21, and the fixed plate 23 is fixedly connected to the bottom of the base 1. When the device needs to move, the motor 24 can drive the roller 22 to rotate, and at the same time drive the device to move, and allow the crops to be placed between the two bases 1. At this time, the pump body 31 will start, and allow water and fertilizer to enter the nozzle 34 through the feed pipe 32 and the discharge pipe 33 in turn. The water and fertilizer will be sprayed through the nozzle 34 and fall on the crops between the two bases 1, so that water and fertilizer can be sprayed on both sides of the crops at the same time. Since the crops are planted in rows, generally The self-propelled fertilizing device will first spray fertilizer on one side of the row of crops, and then move to the other side of the crops to spray fertilizer on it. The present device can directly spray fertilizer on both sides of the crops at the same time without moving to the other side of the crops.

The motor 24 is fixedly connected to the inner wall of the fixed plate 23, and the output end of the motor 24 is fixedly connected to the axis of the roller 22. After the crops grow, the hydraulic cylinder 11 will start and drive the mounting plate 10 to move upward.

The impeller 72 is rotatably connected to the circumferential surface of the transmission rod 71. The elastic rod 73 is fixedly connected to the end of the transmission rod 71 away from the rotating rod 67. When the pump body 31 extracts water and fertilizer, the filter box 35 can block the undissolved fertilizer and additives in the fertilizer box 4 to prevent the undissolved fertilizer and additives from entering the pump body 31 and causing the pump body 31 to be blocked. When the rotating rod 67 rotates, the transmission rod 71 is driven to rotate.

The sealing disk 74 is rotatably connected to the inner wall of the bottom of the fertilizer box 4, the transmission bar 75 is fixedly connected to the inner wall of the sealing disk 74, and the rubber rod 76 is fixedly connected to the inner wall of the bottom of the transmission bar 75; the circumferential surface of the transmission rod 71 is in contact with the transmission bar 75, and a torsion spring is provided between the sealing disk 74 and the fertilizer box 4. The filter box 35 is located on the movement track of the elastic rod 73 When the transmission rod 71 rotates, it pushes the transmission bar 75 to rotate, and the transmission bar 75 drives the sealing disk 74 to rotate. When the transmission rod 71 passes over the transmission bar 75, the torsion spring drives the sealing disk 74 and the transmission bar 75 on its surface to reset. In this way, the reciprocating swing of the transmission bar 75 can be realized, and the transmission bar 75 drives the rubber rod 76 to swing. When the rubber rod 76 swings, it contacts the crops and shakes the crops, so that the water and fertilizer droplets on the surface of the crops fall into the soil and are absorbed by the roots of the crops, which can improve the absorption effect of the crops on the fertilizer and prevent the water droplets from staying on the leaves of the crops. , which causes some water and fertilizer to evaporate under the sunlight, thereby affecting the fertilization effect of crops.

When the elastic rod 73 moves, it contacts and knocks the filter box 35 to prevent undissolved fertilizer and additives from accumulating on the filter box 35, thereby causing the filter box 35 to accumulate and clog. The rubber rod 76 is made of rubber and is relatively soft. Therefore, the contact between the rubber rod 76 and the crops will not cause damage to the crops.A slide 77 is fixedly connected to the bottom of the mounting plate 10.

Two limit rods 710 are fixedly connected to the side of the slide bar 78 away from the cutter 79. The transmission bar 75 is located between the two limit rods 710. The inner wall of the slide 77 contacts the transmission bar 75. When the transmission bar 75 swings, it pushes the limit rod 710 in contact with it to move.

[0026] Working principle: When the device needs to move, the motor 24 can drive the roller 22 to rotate, and at the same time the driving device moves, and the crops are placed between the two bases 1. At this time, the pump body 31 will start, and let the water and fertilizer enter the nozzle 34 through the feed pipe 32 and the discharge pipe 33 in turn. The water and fertilizer will be sprayed out through the nozzle 34 and fall on the crops between the two bases 1, so that water and fertilizer can be sprayed on both sides of the crops at the same time. Since the crops are planted in rows, the general self-propelled fertilizing device will first spray fertilizer on one side of the row of crops, and then move to the crops. The other side of the crop is sprayed with fertilizer, while the present device can directly spray fertilizer on both sides of the crop at the same time without moving to the other side of the crop, which can improve the fertilization efficiency of the device and expand the scope of application of the device. At the same time, after the crops grow, the hydraulic cylinder 11 will start and drive the mounting plate 10 to move upward, and the mounting plate 10 drives the fertilizer box 4 to move upward together through the connecting plate 9, thereby increasing the height of the device, preventing the crops from contacting the fertilizer box 4 after growth, thereby affecting fertilization, so that the device can be applied to crops at different growth stages, further expanding the scope of application of the device;

[0027] When the pump body 31 extracts water and fertilizer, the filter box 35 can block the undissolved fertilizer and additives in the fertilizer box 4, preventing the undissolved fertilizer and additives from entering the pump body 31 and causing the pump body 31 to be blocked. When the rotating rod 67 rotates, it drives the transmission rod 71 to rotate, and the transmission rod 71 drives the impeller 72 to rotate. The impeller 72 can stir the fertilizer and additives that fall into the water, thereby improving the mixing effect of the fertilizer and additives. At the same time, when the transmission rod 71 rotates, it drives the transmission bar 75 to rotate, and the transmission bar 75 drives the sealing disk 74 to rotate. When the transmission rod 71 passes over the transmission bar 75, the torsion spring drives the sealing disk 74 and the transmission bar 75 on its surface to reset. In this way, the reciprocating swing of the transmission bar 75 can be achieved, and the transmission bar 75 drives the rubber rod 76 to swing. When the rubber rod 76 swings, it contacts the crops and shakes the crops, so that the water and fertilizer droplets on its surface fall into the soil and are absorbed by the roots of the crops, which can improve the fertilizer absorption effect of the crops and also prevent the water droplets from staying on the crops. The elastic rod 73 is driven to move in a circular motion when the transmission rod 71 rotates. The elastic rod 73 contacts and knocks the filter box 35 when it moves, preventing undissolved fertilizer and additives from accumulating on the filter box 35, thereby causing the filter box 35 to accumulate and clog. When the transmission bar 75 swings, it pushes the limit rod 710 in contact with it to move. The limit rod 710 drives the slide bar 78 to slide on the slide plate 77. The slide bar 78 drives the cutter 79 to move. The cutter 79 cuts all crops at the same height, making all crops the same height. This can stimulate the development of buds at the bottom or side of the crop, promote the growth of side branches and tillers, and at the same time, through pruning, the plant can maintain a relatively uniform plant shape, avoiding uneven nutrient distribution due to excessively tall plants, thereby affecting the overall health and yield of the crop.
