Description

Technical Field

[0001] This application relates to the field of fertilization technology, specifically to an adjustable fertilization device. Background Technology

[0002] Traditional irrigation canal fertilization typically employs fixed-flow fertilization devices. These devices use a single-aperture fertilizer discharge pipe or a fertilizer release structure with a fixed opening. The fertilizer outlet is placed into the irrigation canal, and the fertilizer flows into the farmland after entering the canal water. The fertilization rate is limited during the design phase. These devices rely on the fertilizer's own weight or a constant water level difference for fertilizer delivery, which has significant drawbacks in practical applications: the fertilization rate cannot be dynamically adjusted according to irrigation needs. When crop nutrient requirements change or canal water flow fluctuates, over- or under-fertilization can easily occur, leading to fertilizer waste or uneven crop growth. To adapt to different fertilization scenarios, multiple sets of discharge pipes with different apertures often need to be pre-configured for replacement, making operation cumbersome and lacking in field applicability. These problems severely restrict the widespread application of fixed-flow devices in precision agricultural irrigation. Therefore, how to manufacture a fertilization device with flexible and adjustable fertilization rates is a technical problem that needs to be solved in this field. Utility Model Content

[0003] In view of this, this application provides an adjustable fertilization device that enables flexible adjustment of the fertilization amount.

[0004] In a first aspect, this application provides an adjustable fertilization device, comprising: a fertilizer conveying pipe including a fertilizer inlet and a fertilizer outlet, the fertilizer inlet being used to input fertilizer, and the outer wall of the fertilizer conveying pipe having threads; and a fertilizer receiving assembly having a fertilizer carrying cavity, the fertilizer receiving assembly having an inlet, the fertilizer outlet extending from the inlet into the fertilizer carrying cavity, the inlet having an embedded ring, the embedded ring being embedded in the threads, and the side wall of the fertilizer receiving assembly having a plurality of first discharge holes, the first discharge holes communicating with the fertilizer carrying cavity.

[0005] In conjunction with the first aspect, in one possible implementation, the abutment wall on the opposite side of the inlet on the fertilizer receiving assembly is a plane, and the abutment wall abuts against or moves away from the fertilizer outlet.

[0006] In conjunction with the first aspect, in one possible implementation, the abutment wall is provided with a plurality of second discharge holes, which are connected to the fertilizer bearing cavity.

[0007] In conjunction with the first aspect, in one possible implementation, a plurality of the second discharge holes constitute a second hole array, wherein the edge of the second hole array is at a distance of 2 cm to 10 cm from the edge of the abutment wall.

[0008] In conjunction with the first aspect, in one possible implementation, the sidewall is an arc surface, and the sidewall protrudes in a direction away from the fertilizer bearing cavity.

[0009] In conjunction with the first aspect, in one possible implementation, a plurality of the first discharge holes constitute a first hole array, the first hole array being arranged around the fertilizer carrying cavity.

[0010] In conjunction with the first aspect, in one possible implementation, the fertilizer delivery pipe is a corrugated pipe.

[0011] In conjunction with the first aspect, one possible implementation further includes: a fixing component connected to the fertilizer delivery pipe, the fixing component also being connected to the body of the irrigation canal, the fixing component being used to relatively fix a portion of the fertilizer delivery pipe and the irrigation canal.

[0012] In conjunction with the first aspect, in one possible implementation, the fixing component includes a connecting rod and a connecting ring, one end of the connecting rod being fixed to the inner wall or top of the channel, the other end of the connecting ring being fixedly connected to the connecting ring, the connecting ring being sleeved and fixed on the fertilizer delivery pipe, and the fertilizer delivery pipe below the connecting ring extending vertically into the irrigation channel.

[0013] In conjunction with the first aspect, one possible implementation further includes: a fertilizer storage component having a fertilizer storage cavity, wherein the fertilizer inlet is connected to the fertilizer storage component.

[0014] In use, the fertilizer inlet is connected to a fertilizer storage component, which can be a fertilizer box containing fertilizer. The fertilizer receiving component is placed in the irrigation canal and submerged below the water surface. The fertilizer storage component is placed on the ground on either side of the irrigation canal. Through gravity, the fertilizer in the storage component flows into the fertilizer receiving component via a fertilizer delivery pipe. The fertilizer delivery pipe can be made of a rigid material, with threads extending vertically downwards into the irrigation canal, allowing the fertilizer receiving component to remain stably submerged. First, the fertilizer receiving component is rotated, during which the embedded ring rotates along the threads until the fertilizer outlet abuts against the bottom wall of the fertilizer receiving cavity. At this point, the abutment wall and the fertilizer outlet are in contact, and only a very small amount of fertilizer enters the fertilizer receiving cavity. Gradually, the fertilizer receiving component is rotated so that the embedded ring moves downwards along the threads, causing the abutment wall and the fertilizer outlet to move further apart, thereby increasing the amount of fertilizer entering the fertilizer receiving cavity. Because the fertilizer receiving component is submerged below the water surface in the irrigation canal, the fertilizer entering the fertilizer receiving cavity is mixed with the water by the flushing action of the canal water and flows out through the first discharge hole, thus fertilizing the irrigation canal water. The structure of this application allows for simple, convenient, and flexible adjustment of the fertilizer application rate in the irrigation canal using the fertilizer receiving component.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] An example adjustable fertilization device is as follows:

[0021] Figure 1 The diagram shown is a structural schematic of an adjustable fertilization device provided in an embodiment of this application. Figure 2 The diagram shown is a partial structural schematic of an adjustable fertilization device according to an embodiment of this application. In one embodiment, as... Figure 1 and 2 As shown, the adjustable fertilization device includes a fertilizer delivery pipe 1 and a fertilizer receiving assembly 2. The fertilizer delivery pipe 1 includes a fertilizer inlet 101 and a fertilizer outlet 102. The fertilizer inlet 101 is used to input fertilizer, and the outer wall of the fertilizer delivery pipe 1 is provided with threads 103. The fertilizer receiving assembly 2 has a fertilizer carrying cavity 201. The fertilizer receiving assembly 2 has an inlet 202, and the fertilizer outlet 102 extends into the fertilizer carrying cavity 201 from the inlet 202. The inlet 202 is provided with an embedded ring 203. The embedded ring 203 is a ring body, and the inlet 202 is a circular hole. The outer ring wall of the embedded ring 203 is connected to the inner wall of the inlet 202, and the inner ring wall of the embedded ring 203 is embedded in the grooves of the threads 103. The side wall of the fertilizer receiving assembly 2 is provided with a plurality of first discharge holes 204, and the first discharge holes 204 are connected to the fertilizer carrying cavity 201.

[0022] In this embodiment, the fertilizer inlet 101 is connected to the fertilizer storage component 10, which can be a fertilizer box containing fertilizer. The fertilizer receiving component 2 is placed in the irrigation canal 11 and submerged below the water surface. The fertilizer storage component 10 is placed on the ground on both sides of the irrigation canal 11. Under gravity, the fertilizer in the fertilizer storage component 10 enters the fertilizer receiving component 2 through the fertilizer delivery pipe 1. The fertilizer delivery pipe 1 can be made of a relatively rigid material, with a threaded pipe body 103 extending vertically downwards into the irrigation canal 11, thereby allowing the fertilizer receiving component 2 to be stably held in the canal water. First, rotate the fertilizer receiving assembly 2. During this rotation, the embedded ring 203 moves along the thread 103 until the fertilizer outlet 102 abuts against the abutment wall 205 at the bottom of the fertilizer carrying cavity 201. At this point, the abutment wall 205 and the fertilizer outlet 102 are in contact, and only a very small amount of fertilizer enters the fertilizer carrying cavity 201. Gradually rotate the fertilizer receiving assembly 2 so that the embedded ring 203 moves downward along the thread 103, and the abutment wall 205 and the fertilizer outlet 102 gradually move away from each other, thereby increasing the amount of fertilizer entering the fertilizer carrying cavity 201. Since the fertilizer receiving assembly 2 is submerged below the water surface, the fertilizer entering the fertilizer carrying cavity 201 is mixed with the water by the flushing action of the water and flows out from the first discharge hole 204, thus fertilizing the water in the irrigation canal 11. Through the structure of this embodiment, the amount of fertilizer applied by the fertilizer receiving assembly 2 in the irrigation canal 11 can be easily, conveniently, and flexibly adjusted.

[0023] Specifically, the abutment wall 205 on the opposite side of the inlet 202 of the fertilizer receiving component 2 is a plane, and the abutment wall 205 is either in contact with or away from the fertilizer outlet 102.

[0024] Figure 3 The diagram shown is a structural schematic of an abutment wall provided in one embodiment of this application. In one embodiment, as... Figure 3 As shown, the abutting wall 205 has multiple second discharge holes 206, which are connected to the fertilizer carrying cavity 201, so that even when the abutting wall 205 and the fertilizer outlet 102 are in contact with each other, a certain amount of fertilizer can enter the irrigation canal 11 through the second discharge holes 206.

[0025] In one embodiment, a plurality of second discharge holes 206 constitute a second hole array, and the edge of the second hole array is at a distance of 2 cm to 10 cm from the edge of the abutment wall 205, thereby ensuring that the edge strength of the abutment wall 205 is not affected by the second discharge holes 206.

[0026] like Figure 1 and 2As shown, the sidewall is curved and protrudes away from the fertilizer bearing cavity 201, thereby increasing the volume of the fertilizer bearing cavity 201. Specifically, multiple first discharge holes 204 constitute a first hole array, which is arranged around the fertilizer bearing cavity 201.

[0027] In one embodiment, the fertilizer delivery pipe 1 is a corrugated pipe, the corrugated part of which forms a thread 103, and the embedded ring 203 is connected to the corrugated pipe.

[0028] Figure 4 The diagram shows a schematic of an adjustable fertilization device mounted on an irrigation canal. In one embodiment, as shown... Figure 4 As shown, the adjustable fertilization device also includes a fixing component 3, which is connected to the fertilizer delivery pipe 1 and the irrigation canal 11. The fixing component 3 is used to fix part of the fertilizer delivery pipe 1 and the irrigation canal 11 relatively.

[0029] In one embodiment, such as Figure 1 As shown, the adjustable fertilization device also includes a fertilizer storage component 10. The fertilizer storage component 10 can be a box-shaped structure. The fertilizer storage component 10 has a fertilizer storage cavity containing fertilizer. The fertilizer inlet 101 is connected to the fertilizer storage component 10.

[0030] In one embodiment, such as Figure 4 As shown, the fixing component 3 includes a connecting rod 301 and a connecting ring 302. One end of the connecting rod 301 is fixed to the inner wall or top of the channel, and the other end of the connecting ring 302 is fixedly connected to it. The connecting ring 302 is sleeved and fixed on the fertilizer conveying pipe 1. The inner ring wall of the connecting ring 302 is fixedly connected to the outer wall of the fertilizer conveying pipe 1, which can be achieved by expansion joint, threaded connection, adhesive connection, etc. The fertilizer conveying pipe 1 below the connecting ring 302 extends vertically into the irrigation channel 11, and the fertilizer conveying pipe 1 above the connecting ring 302 extends and connects to the fertilizer storage component 10, so that the height of the fertilizer inlet 101 is higher than that of the connecting ring 302, thereby allowing the fertilizer in the fertilizer storage component 10 to pass through the connecting ring 302 under the action of gravity and be output from the fertilizer outlet 102. The connecting rod 301 can be used to install the connecting ring 302 above the irrigation canal 11, that is, to install a part of the fertilizer delivery pipe 1 above the irrigation canal 11, and the fertilizer delivery pipe 1 below the connecting ring 302 extends vertically downward into the irrigation canal 11 and connects with the fertilizer receiving component 2.
