[0002] Liquid fertilizer fertilization device is a device used to evenly apply liquid fertilizer to the roots of farmland, greenhouse or garden plants, which can improve fertilization efficiency, save fertilizer and reduce environmental pollution. This device is widely used in precision agriculture and efficient water and fertilizer management systems.

[0003] For the growth of crops, timely providing them with sufficient nutrients is very helpful to promote their growth, so in life, crops are often fertilized on time. Among them, amino acid liquid fertilizer has many advantages such as sufficient nutrition and easy absorption by crops.

[0004] When using amino acid liquid fertilizer for fertilization, the prior art inevitably encounters problems such as uneven mixing of the amino acid liquid fertilizer and long-term fertilization causing the substances therein to deposit at the nozzle and clog the nozzle. Summary of the invention

[0005] Based on this, it is necessary to provide an amino acid liquid fertilizer fertilization device and a fertilization method to address the problems of uneven mixing of the current amino acid liquid fertilizer and long-term fertilization causing the substances therein to settle and block the nozzles.

[0006] The above purpose is achieved through the following technical solutions:

[0007] An amino acid liquid fertilizer fertilizing device, comprising:

[0008] A traction frame, on which a solution tank is fixedly arranged, wherein the solution tank has two chambers, one of which is filled with concentrated amino acid liquid fertilizer, and the other is filled with warm water;

[0009] A spray swing arm, one end of which is rotatably connected to the traction frame, and the spray swing arm can swing along the rotational connection position at a preset angle, a spray barrel is installed on the spray swing arm, and a liquid fertilizer pipeline and a warm water pipeline are arranged at the upper end of the spray barrel, and the liquid fertilizer pipeline and the warm water pipeline are respectively connected to the two chambers of the solution tank, and a spray hole is opened at the lower end of the spray barrel;

[0010] A rotating disk is rotatably arranged inside the spray barrel, through holes inclined along the same circumferential direction are evenly opened on the rotating disk, stirring tubes are evenly arranged on the rotating disk, concentrated liquid fertilizer and warm water enter the spray barrel to dissolve, and the dissolved liquid can drive the rotating disk to rotate through the through holes, and the rotating disk drives the stirring tube to stir the concentrated liquid fertilizer and warm water.

[0011] Furthermore, the stirring tube is connected to the through hole, and the axis of the stirring tube connection coincides with the axis of the through hole.

[0012] Furthermore, the heights of the plurality of stirring tubes gradually increase or decrease along the circumference of the rotating disk.

[0013] Furthermore, the stirring tube is in a spiral shape.

[0014] Furthermore, a switch assembly is provided on the spray barrel, and the switch assembly is configured as follows:

[0015] When the spray barrel is blocked by crops, the spray hole is closed;

[0016] When the spray barrel is not blocked by crops, the spray hole is opened.

[0017] Furthermore, the end surface where the spray hole is located can move along the axial direction of the spray barrel, the spray hole and the through hole are arranged alternately, and the switch assembly includes a sensing rod, the sensing rod is arranged on the spray swing arm, and the sensing rod abuts against the end surface where the spray hole is located;

[0018] When the sensing rod contacts the crop, it pushes the end surface where the spray hole is located to abut against the rotating disk, and the rotating disk blocks the spray hole;

[0019] When the sensing rod does not contact the crop, the sensing rod is reset, and the end surface where the spray hole is located is away from the rotating disk.

[0020] Furthermore, the switch assembly also includes a telescopic rod, and the telescopic rod is located between the spray swing arm and the sensing rod.

[0021] Furthermore, a sliding plate capable of sliding axially along the spray tube is provided in the spray tube, and an elastic member is provided between the sliding plate and the top of the spray tube.

[0047] Refer to the following Figure 1-Figure 9 To describe an amino acid liquid fertilizer fertilizing device provided by the present invention.

[0048] An amino acid liquid fertilizer fertilizing device, suitable for fertilizing crops, includes a traction frame 100. The traction frame 100 can be connected to a tractor (not shown in the figure). The tractor pulls the traction frame 100 to move in the farmland. The traction frame 100 is provided with a solution tank 110. The solution tank 110 has two chambers. One of the two chambers is filled with concentrated amino acid liquid fertilizer, and the other chamber is filled with warm water. A spray swing arm 200 is rotatably connected to one side of the traction frame 100. The spray swing arm 200 can swing a certain angle along the rotation connection position. The present invention takes the swing of 80° as an example. There are two spray swing arms 200, and the two spray swing arms 200 are symmetrically arranged, such as Figure 2 As shown, both spray swing arms 200 rotate 80°, and a hydraulic cylinder 210 is provided on the traction frame 100. One end of the hydraulic cylinder 210 is hinged on the spray swing arm 200, and the other end of the hydraulic cylinder 210 is hinged on the traction frame 100. The hydraulic cylinder 210 can adjust the angle of the spray swing arm 200 by telescoping. A spray barrel 300 is provided on the spray swing arm 200. The upper end of the spray barrel 300 is connected to the liquid fertilizer pipeline 120 and the warm water pipeline 130. The liquid fertilizer pipeline 120 and the warm water pipeline 130 are fixed on the spray swing arm 200. The other ends of the liquid fertilizer pipeline 120 and the warm water pipeline 130 are connected to the two chambers of the solution tank 110 respectively, that is, the liquid fertilizer pipeline 120 is connected to the chamber filled with concentrated amino acid liquid fertilizer, and the warm water pipeline 130 is connected to the chamber filled with warm water.

[0049] A spray hole 310 is provided at the bottom of the spray barrel 300, and the concentrated amino acid liquid fertilizer and warm water in the two chambers of the solution barrel are introduced into the spray barrel 300 through the liquid fertilizer pipe 120 and the warm water pipe 130, and the two are mixed in the spray barrel 300, and then sprayed out through the spray hole 310, and the amino acid liquid fertilizer falls on the soil, thereby completing the fertilization of the farmland.

[0050] When the amino acid liquid fertilizer in the prior art is loaded into the solution tank 110 and sprayed, the amino acid liquid fertilizer in the solution tank 110 may be stationary, resulting in a decrease in mixing uniformity. Therefore, the present invention provides a structure capable of stirring the amino acid liquid fertilizer in the spray barrel 300, so that the amino acid liquid fertilizer is in a uniformly mixed state when sprayed out from the spray barrel 300, thereby avoiding the above situation.

[0051] The specific structure is as follows: a rotating disk 320 is arranged in the spray cylinder 300, and the rotating disk 320 can rotate circumferentially relative to the spray cylinder 300, and a plurality of through holes 330 inclined along the circumferential direction of the rotating disk 320 are evenly opened on the rotating disk 320, and all are inclined along the same circumferential direction. At the same time, stirring tubes 340 are evenly arranged on the rotating disk 320 in a circumferential direction. When the concentrated amino acid liquid fertilizer and the warm water enter the spray barrel 300, the two are mixed with each other and will pass through the through holes 330 on the rotating disk 320, and then sprayed out through the spray holes 310. When the amino acid liquid fertilizer passes through the through holes 330 on the rotating disk 320, since the through holes 330 of the rotating disk 320 are inclined along the circumferential direction of the rotating disk 320, the amino acid liquid fertilizer will be tilted and sprayed out of the through holes 330 when passing through the through holes 330, and the amino acid liquid fertilizer will generate a reaction force on the rotating disk 320, so that the rotating disk 320 rotates, and the rotating disk 320 rotates with the stirring tube 340 synchronously, so that the stirring tube 340 stirs and mixes the concentrated amino acid liquid fertilizer and the warm water, so that the mixing effect of the two is better.

[0052] It can be understood that by setting up a mixture of warm water and concentrated amino acid liquid fertilizer, the concentrated amino acid liquid fertilizer can be diluted while avoiding frosting, and a rotating disk 320 and a stirring tube 340 are set on the inner wall of the spray barrel 300, and the concentrated amino acid liquid fertilizer and warm water pass through the inclined through hole 330 to give the rotating disk 320 a driving force to rotate, so that the rotating disk 320 drives the stirring tube 340 to stir the concentrated amino acid liquid fertilizer and warm water, thereby improving the mixing uniformity of the two.

[0053] It should be noted that the inclined through hole 330 can not only drive the rotating disk 320 to rotate, but also make the amino acid liquid fertilizer sprayed obliquely generate eddy current when entering the cavity at the bottom of the rotating disk 320 and the spray barrel 300, that is, make the amino acid liquid fertilizer flow in a spiral, thereby cleaning the bottom of the spray barrel 300 and effectively avoiding blockage of the spray hole 310.

[0054] In order to facilitate the concentrated amino acid liquid fertilizer and warm water to be passed into the spray barrel 300, a diaphragm pump 140 is arranged on the traction frame 100. The diaphragm pump 140 is connected to the liquid fertilizer pipeline 120 and the warm water pipeline 130. When the diaphragm pump 140 is working, the concentrated amino acid liquid fertilizer and warm water in the two chambers of the solution tank 110 can be pumped into the spray barrel 300. At the same time, a heater (not shown in the figure) is arranged in one of the two chambers of the solution tank 110 that is filled with warm water. The heater is used to keep the temperature of the warm water constant to avoid the temperature of the warm water from decreasing, thereby making the mixing effect of the warm water and the concentrated amino acid liquid fertilizer better, and further avoiding the frosting phenomenon of the amino acid liquid fertilizer.

[0055] In a further embodiment, the stirring tube 340 is connected to the through hole 330, and the axis of the connection position between the stirring tube 340 and the through hole 330 coincides with the axis of the inclined through hole 330, that is, the stirring tube 340 is also inclined, so as to adapt to the inclined through hole 330. The mixed liquid entering the spray cylinder 300 will pass through multiple stirring tubes 340, and then pass through the inclined through hole 330 into the cavity between the rotating disk 320 and the bottom of the spray cylinder 300, and finally be sprayed out through the spray hole 310.

[0056] By connecting the stirring tube 340 and the through hole 330 together, the concentrated amino acid liquid fertilizer and warm water at a higher position can enter the stirring tube 340 .

[0057] In a further embodiment, the heights of the plurality of stirring tubes 340 of the present invention are different, and the heights of the plurality of stirring tubes 340 gradually increase or decrease along the circumference of the rotating disk 320, such as Fig. 9 As shown, the height of the plurality of stirring tubes 340 is in a clockwise direction (in Fig. 9 The height of the plurality of stirring tubes 340 gradually increases in the clockwise direction (as viewed from top to bottom), or the height of the plurality of stirring tubes 340 gradually increases in the counterclockwise direction (as viewed from top to bottom). Fig. 9 The structure is set so that the amino acid liquid fertilizer at different heights in the spray barrel 300 can pass through the through hole 330 and be sprayed out through the spray hole 310, and the mixing degree of the sprayed amino acid liquid fertilizer is more uniform.

[0058] Specifically, the stirring tube 340 in this embodiment is in a spiral shape, and the spiral stirring tube 340 has a better stirring effect on the amino acid liquid fertilizer, further improving the mixing uniformity of the amino acid liquid fertilizer. At the same time, it can increase the time for the amino acid liquid fertilizer to pass through the stirring tube 340, so that the spiral flow effect of the amino acid liquid fertilizer when passing through the through hole 330 is stronger, thereby improving the cleaning effect of the amino acid liquid fertilizer on the bottom of the spray cylinder 300 when the spiral flow is improved, and further avoiding the spray hole 310 from being blocked.

[0059] In a further embodiment, in order to avoid affecting the growth of crops and generating no waste, when the spray cylinder 300 is blocked by crops, the spray holes 310 of the spray cylinder 300 are closed, and when the spray cylinder 300 is not blocked by crops, the spray holes 310 of the spray cylinder 300 are opened.

[0060] Specifically, this embodiment uses a switch component to achieve the above functions. The switch component can close the spray hole 310 of the spray cylinder 300 when the spray cylinder 300 is blocked by crops, and open the spray hole 310 of the spray cylinder 300 when the spray cylinder 300 is not blocked by crops.

[0061] More specifically, the switch assembly includes a sensing rod 220, which is disposed on the spray swing arm 200. The sensing rod 220 abuts against the bottom end of the spray cylinder 300. The bottom end of the spray cylinder 300 in this embodiment can move along the axial direction of the spray cylinder 300, and the multiple spray holes 310 on the bottom end of the spray cylinder 300 are staggered with the multiple through holes 330. For example, the circumferential radius of the multiple spray holes 310 is greater than or smaller than the circumferential radius of the multiple through holes 330. When the sensing rod 220 contacts the crops, it indicates that the crops are under the spray barrel 300, so the sensing rod 220 at this time pushes the bottom end of the spray barrel 300 to move toward the rotating disk 320 until the bottom end of the spray barrel 300 contacts the rotating disk 320 and stops. The through hole 330 on the rotating disk 320 and the spray hole 310 at the bottom end of the spray barrel 300 do not correspond to each other, so the spray hole 310 is blocked, and the amino acid liquid fertilizer in the spray barrel 300 cannot be sprayed out, thereby protecting the crops, preventing the amino acid liquid fertilizer from falling on the crops, and avoiding the waste of the amino acid liquid fertilizer. When the sensing rod 220 is not in contact with the crops, the sensing rod 220 is reset, and the bottom of the spray barrel 300 is reset under the action of gravity when it is not pushed by the sensing rod 220, and the bottom end of the spray barrel 300 and the rotating disk 320 move away from each other, so that the spray hole 310 at the bottom end of the spray barrel 300 is reopened, and the amino acid liquid fertilizer in the spray barrel 300 is sprayed out through the spray hole 310.

[0062] In a further embodiment, the switch assembly of the present invention further comprises a telescopic rod 230, one end of which is fixedly arranged on the spray swing arm 200, and the other end of which is fixedly arranged on the sensing rod 220. The telescopic rod 230 is in an extended state in an initial state. When the traction frame 100 moves, the sensing rod 220 on the spray swing arm 200 contacts the crops, and the crops push the sensing rod 220, and the sensing rod 220 pushes the telescopic rod 230 to make the telescopic rod 230 retract. The sensing rod 220 pushes the bottom end of the spray barrel 300, so that the spray hole 310 on the bottom end of the spray barrel 300 is blocked. As the traction frame 100 moves, the sensing rod 220 moves to a position where there is no crop blocking. The sensing rod 220 no longer pushes the telescopic rod 230 and the bottom end of the spray barrel 300, and the sensing rod 220 is pushed to reset by the telescopic rod 230. At the same time, the bottom end of the spray barrel 300 is also reset under the action of gravity, so that the bottom end of the spray barrel 300 can continue to spray amino acid liquid fertilizer.

[0063] Specifically, when the spray hole 310 is blocked, the liquid fertilizer pipeline 120 and the warm water pipeline 130 do not stop transporting concentrated amino acid liquid fertilizer and warm water. In order to prevent the spray cylinder 300 from being subjected to a large pressure, a sliding plate 350 that can slide along the axial direction of the spray cylinder 300 is provided in the spray cylinder 300, and an elastic member 360 is provided between the sliding plate 350 and the top of the spray cylinder 300. The elastic member 360 is a spring. In the initial state, the elastic member 360 is in the original length state, and the initial position of the sliding plate 350 is located above the openings of the liquid fertilizer pipeline 120 and the warm water pipeline 130. When the liquid fertilizer pipe 120 and the warm water pipe 130 inject concentrated amino acid liquid fertilizer and warm water into the spray barrel 300, they are not affected by the sliding plate 350 and can work normally. Only when the spray hole 310 is blocked, as the pressure in the spray barrel 300 increases, when the pressure can overcome the elastic force of the elastic member 360, the sliding plate 350 will compress the elastic member 360 to move toward the top of the spray barrel 300, thereby increasing the volume inside the spray barrel 300 to adapt to the increase in internal pressure, thereby avoiding the occurrence of rupture when the pressure in the spray barrel 300 exceeds the safety value.

[0064] It should be noted that the elastic member 360 with a suitable stiffness coefficient can be selected according to the conveying speed of the liquid fertilizer pipeline 120 and the warm water pipeline 130, or the conveying speed of the liquid fertilizer pipeline 120 and the warm water pipeline 130 can be adjusted according to the elastic coefficient of the elastic member 360, so as to avoid excessive pressure in the spray barrel 300, which is not specifically limited here.

[0065] In a further embodiment, a plurality of spray barrels 300 may be provided on the spray swing arm 200 of the present invention, so as to improve the fertilization efficiency of the amino acid liquid fertilizer. Of course, only one spray barrel 300 is shown in this embodiment, which does not mean that only one spray barrel 300 can be provided. The number of spray barrels 300 is set according to needs, and will not be elaborated herein.

[0066] The specific working process of an amino acid liquid fertilizer fertilization device provided by the present invention is described in combination with the above embodiments:

[0067] Loading:

[0068] The prepared concentrated amino acid liquid fertilizer is filled into one chamber of the solution tank 110 , and warm water of suitable temperature is filled into another chamber of the solution tank 110 .

[0069] start up:

[0070] After planning the route of the traction frame 100 as needed and adjusting the angles of the two spray swing arms 200, the diaphragm pump 140 is started. The diaphragm pump 140 passes the concentrated amino acid liquid fertilizer and warm water in the solution tank 110 into the spray barrel 300 through the liquid fertilizer pipeline 120 and the warm water pipeline 130. The concentrated amino acid liquid fertilizer and warm water entering the spray barrel 300 are dissolved with each other to avoid frosting of the concentrated amino acid liquid fertilizer. The dissolved amino acid liquid fertilizer passes through the spiral stirring tube 340 and enters through the inclined through hole 330. To the cavity between the rotating disk 320 and the bottom end of the spray barrel 300, due to the spiral stirring tube 340 and the inclined through hole 330, the amino acid liquid fertilizer forms a spiral flow mode, thereby giving the rotating disk 320 a driving force to rotate, and the rotating disk 320 drives the spiral stirring tube 340 to stir the concentrated amino acid liquid fertilizer and warm water, thereby improving the mixing uniformity of the amino acid liquid fertilizer. At the same time, the spirally flowing amino acid liquid fertilizer can clean the bottom end of the spray barrel 300 to avoid clogging of the spray hole 310 at the bottom end of the spray barrel 300.

[0071] Automatically control the opening and closing of the spray hole 310:

[0072] When the spray arm 200 passes through the crops, the sensing rod 220 on the spray arm 200 comes into contact with the crops, the crops push the sensing rod 220, the sensing rod 220 pushes the telescopic rod 230, the telescopic rod 230 is compressed, and at the same time the sensing rod 220 comes into contact with the bottom end of the spray barrel 300, thereby also pushing the bottom end of the spray barrel 300 to move toward the rotating disk 320. When the two come into contact, the spray holes 310 at the bottom end of the spray barrel 300 and the through holes 330 on the rotating disk 320 are staggered, so the rotating disk 320 blocks the spray holes 310 at the bottom end of the spray barrel 300, thereby preventing the amino acid liquid fertilizer in the spray barrel 300 from being sprayed on the crops and affecting the crops, and also avoiding the waste of the amino acid liquid fertilizer. As the spray hole 310 is blocked, the diaphragm pump 140 does not stop working. When the pressure in the spray barrel 300 gradually increases, the amino acid liquid fertilizer in the spray barrel 300 pushes the sliding plate 350 to push the elastic member 360, thereby increasing the volume in the spray barrel 300, thereby adapting to the increase in internal pressure of the spray barrel 300, thereby avoiding the occurrence of rupture of the spray barrel 300.

[0073] As the traction frame 100 moves, the crops under the spray swing arm 200 are separated from the sensing rod 220, and the sensing rod 220 is reset due to the extension of the telescopic rod 230. At the same time, the sensing rod 220 no longer pushes the bottom end of the spray cylinder 300, and the bottom end of the spray cylinder 300 is reset under the action of gravity, and the bottom end of the spray cylinder 300 is separated from the rotating disk 320, so that the spray hole 310 at the bottom end of the spray cylinder 300 is opened, and the amino acid liquid fertilizer can continue to be sprayed.

[0074] The traction frame 100 travels along a set route to complete the fertilization operation on the crops.

[0075] The present invention also provides an amino acid liquid fertilizer fertilization method, which is applicable to the above-mentioned amino acid liquid fertilizer fertilization device and specifically comprises the following specific steps:

[0076] Step S100: preparing concentrated amino acid liquid fertilizer, and filling the prepared concentrated amino acid liquid fertilizer and warm water into the solution tank 110, and preparing for spraying;

[0077] After the concentrated amino acid liquid fertilizer is prepared according to the type of crops, the concentrated amino acid liquid fertilizer and warm water are respectively filled into the two cavities of the solution tank 110, and the diaphragm pump 140 is started to pump the concentrated amino acid liquid fertilizer and warm water into the spray barrel 300 to prepare for the spraying operation.

[0078] Step S200: setting a spraying path to evenly spray the amino acid liquid fertilizer;

[0079] Among them, a suitable spraying path is set according to the distribution and type of crops, a tractor is used to pull the tractor frame 100 to move along the set path, and the two spray swing arms 200 are regulated by the hydraulic cylinder 210 to swing 80° to form a fan-shaped spraying area. The multiple spray barrels 300 on the spray swing arms 200 can evenly spray the amino acid liquid fertilizer, and the operator can drive the tractor to spray according to the set path.

[0080] Step S300: completing the spraying operation.

[0081] After the operator drives the traction vehicle according to the set path, the spraying operation is completed, the diaphragm pump 140 is turned off, and the hydraulic cylinder 210 is adjusted to reset the two spray swing arms 200 to complete the spraying operation.

[0082] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
