Description

Technical Field

[0001] The invention relates to the technical field of medicinal material fertilization, and in particular to a medicinal material fertilization device. Background Art

[0002] Foliar fertilization, also known as foliar fertilization, is a method of fertilizing medicinal plants during their growth period by spraying a dilute solution of inorganic fertilizers, trace elements or growth hormones, so that the fertilizer solution can enter the plant body from the stomata of leaves and branches with the help of water movement. This method is often used in the cultivation of Chinese herbal medicines and has the advantages of strong targeting, fast absorption, no influence from soil environmental factors, and high nutrient utilization rate.

[0003] The fertilizer applied by foliar fertilization is water-fertilizer. The traditional manual fertilization method is not only labor-intensive and inefficient, but also often has the problem of uneven fertilization, which leads to uneven growth of medicinal materials and affects the overall quality. In addition, it is difficult to accurately control the spraying range and measurement when manually spraying water and fertilizer, which easily causes waste of water and fertilizer or local overdose, causing adverse effects on the soil and the medicinal materials themselves.

[0037] Example

[0038] like Figure 1-Figure 7 As shown, a medicinal material fertilizing device includes a fertilizer spraying mechanism 100, which includes a guide ring 110. The guide ring 110 is placed on the ground, and the medicinal material is located near the center of the guide ring 110. Two vertical rods 120 are symmetrically slidably connected to the guide ring 110, and nozzles 140 are provided on the two vertical rods 120; the two vertical rods 120 can synchronously slide along the guide ring 110 for half a circle stroke, and when the vertical rods 120 slide, the nozzles 140 spray water and fertilizer to the medicinal material.

[0039] The working mechanism of the fertilization device provided in this embodiment is as follows:

[0040] When in use, place the guide ring 110 on the ground so that the medicinal materials are in the middle center of the guide ring 110. When the medicinal materials need to be sprayed, water and fertilizer are supplied to the nozzle 140 so that the nozzle 140 sprays water and fertilizer to the leaves and other parts of the medicinal materials. At the same time, the vertical rod 120 slides on the guide ring 110, thereby driving the nozzle 140 to move and spray around the medicinal materials, so that water can be fully sprayed onto the medicinal materials. The two vertical rods 120 respectively slide synchronously on the guide ring 110 for half a circle to ensure that the fertilizer can be evenly sprayed on the medicinal materials.

[0041] Regarding how to drive the upright pole 120 to slide on the guide ring 110, specifically:

[0042] The fertilizer spraying mechanism 100 also includes a vertical plate 170, in which a slider 310 is slidably connected, an active cylinder 320 is connected to the middle of the slider 310, and two passive cylinders 150 are connected to the two sides, the cylinder body of the passive cylinder 150 is connected to the slider 310, and the cylinder rod of the passive cylinder 150 is connected to the output end of the active cylinder 320; two arc cylinders 160 are connected to the guide ring 110, and the two arc cylinders 160 are respectively connected to the two passive cylinders 150.

[0043] When spraying fertilizer on medicinal materials, first control the active cylinder 320 to extend. At this time, the output end of the active cylinder 320 drives the cylinder rod of the passive cylinder 150 to move upward through the second fixed rod 152, and the cylinder body of the passive cylinder 150 is fixedly connected to the slider 310 through the first fixed rod 151, and the active cylinder 320 is also fixedly connected to the slider 310, so that the cylinder rod of the passive cylinder 150 can be shortened at this time, so that the gas in the passive cylinder 150 is transferred to the arc cylinder 160 through the air pipe 153. At this time, the arc cylinder 160 extends, so that the vertical rod 120 connected to its output end slides on the guide ring 110. When the active cylinder 320 is shortened, the passive cylinder 150 extends, so that the arc cylinder 160 is shortened, so that the vertical rod 120 is reset.

[0044] Regarding the structure further including the swing mechanism 200, specifically:

[0045] The swing mechanism 200 includes a vertical plate 240, on which a through hole 260 is provided to fit the nozzle 140; the vertical rod 120 is connected to a mounting block 130, on which the vertical plate 240 slides vertically, and when the vertical plate 240 slides vertically back and forth, it drives the nozzle 140 to swing up and down.

[0046] The vertical plate 240 is connected to the mounting block 130 so that it can slide vertically relative to the vertical rod 120 without rotating axially around the vertical rod 120. The nozzle 140 is inserted into the insertion hole 260 on the vertical plate 240, and the aperture of the insertion hole 260 is larger than the diameter of the nozzle 140. The vertical movement stroke of the vertical plate 240 will not be greatly reduced by the influence of the nozzle 140. Moreover, when the vertical plate 240 moves vertically back and forth, the nozzle 140 can be pushed up and swung through the bottom wall of the insertion hole 260, and the nozzle 140 can be pulled down and swung through the top wall of the insertion hole 260, so that the nozzle 140 can also swing up and down when moving along the guide ring 110, which not only ensures the fertilization range of the medicinal materials, but also allows the upper and lower sides of the leaves of the medicinal materials to be sprayed with water and fertilizer, thereby ensuring the fertilization effect.

[0047] Among the optional methods of this embodiment, the more preferred ones are:

[0048] The swing mechanism 200 also includes a rotating rod 210, which rotates on a fixed axis at the bottom of the vertical rod 120. A turntable 220 and a cam 230 are connected to the rotating rod 210. The turntable 220 rolls on the guide ring 110. A horizontal plate 250 is connected to the vertical plate 240, and the side wall of the cam 230 is attached to the horizontal plate 250. When the vertical rod 120 slides along the guide ring 110, the turntable 220 rolls on the guide ring 110, so that the rotating rod 210 rotates so that the cam 230 drives the vertical plate 240 to slide vertically back and forth.

[0049] When the vertical rod 120 slides along the guide ring 110, the turntable 220 can roll on the guide ring 110. In addition, in order to ensure the stable rotation of the turntable 220, anti-slip grooves can be provided at the contact position between the turntable 220 and the guide ring 110, or mutually meshing teeth can be provided on the guide ring 110 and the turntable 220 respectively; when the turntable 220 rotates, the rotating rod 210 rotates, so that the cam 230 connected to the end of the rotating rod 210 rotates, and at this time, the cam 230 intermittently pushes the horizontal plate 250, so that the vertical plate 240 can move up and down.

[0050] Regarding the structure of the sprinkler irrigation height adjustment mechanism 300, specifically:

[0051] The sprinkler height adjustment mechanism 300 includes a limit rod 340 that slides symmetrically on both sides of the slider 310, a spring 350 is connected between the limit rod 340 and the slider 310, the end of the limit rod 340 is provided with a rounded corner, and a plurality of limit grooves 360 that cooperate with the limit rod 340 are opened on the vertical plate 170; multiple nozzles 140 are arranged along the axial direction of the vertical rod 120, and the multiple nozzles 140 are connected to branch pipes, and the multiple branch pipes are commonly connected to the supply pipe 370. The multiple branch pipes except the lowest one are all provided with solenoid valves, and the multiple limit grooves 360 except the one closest to the vertical plate 170 are all provided with pressure-sensitive switches. When the slider 310 slides in the direction away from the vertical plate 170, the multiple solenoid valves are opened in sequence from bottom to top and maintained in an open state, and when the slider 310 slides in the direction close to the vertical plate 170, the multiple solenoid valves are closed in sequence from top to bottom and maintained in a closed state.

[0052] A plurality of nozzles 140 are arranged on the vertical pole 120, and the plurality of nozzles 140 are opened in sequence from bottom to top. When the number of nozzles 140 opened increases, it can be adapted to spray fertilizer on higher medicinal materials. Water fertilizer flows in the supply pipe 370, and a plurality of branch pipes are connected on the supply pipe 370, which are respectively the first branch 371, the second branch 372 and the third branch 373 from bottom to top. Except for the first branch 371, the remaining branch pipes are all provided with electromagnetic valves. A plurality of limit grooves 360 are opened on the vertical plate 170, and the plurality of limit grooves 360 They are arranged linearly in the direction from close to the vertical plate 170 to far away from it, and the limit groove 360 ​​closest to the vertical plate 170 corresponds to the first branch 371, and so on; the pressure-sensitive switch arranged in the second limit groove 360 ​​far away from the vertical plate 170 is used to control the opening of the solenoid valve of the second branch 372, and the pressure-sensitive switch arranged in the third limit groove 360 ​​far away from the vertical plate 170 is used to control the opening of the solenoid valves of the second branch 372 and the third branch 373 together, and so on. Multiple branch pipes and nozzles 140 can be set according to the height of the medicinal materials.

[0053] Among the optional methods of this embodiment, the more preferred ones are:

[0054] A tension spring 380 is connected between the slider 310 and the vertical plate 170 .

[0055] The setting of the spring 350 ensures that the limit rod 340 can be pushed and positioned in the limit groove 360, and the rounded corner of the end of the limit rod 340 is inserted in the limit groove 360, ensuring that the limit rod 340 can be separated from the limit groove 360 ​​after a resistance push-pull force is applied to the slider 310. The tension spring 380 applies a pulling force to the slider 310. When the limit rod 340 is not in the limit groove 360, the tension spring 380 pulls the slider 310 to slide in a direction close to the vertical plate 170, so that the slider 310 can be fixed in a specific position when the equipment is in working state. In addition, an electric telescopic rod can be provided to control the sliding of the slider 310. When the electric telescopic rod is provided, the tension spring 380 can be omitted.

[0056] Regarding the structure of the fertilizer amount adaptive adjustment mechanism 400, specifically:

[0057] The fertilizer amount adaptive adjustment mechanism 400 includes a piston cylinder 410, which is connected to the supply pipe 370. The piston cylinder 410 is connected to an extraction pipe 430, and the extraction pipe 430 is connected to an external water and fertilizer supply. Both the supply pipe 370 and the extraction pipe 430 are provided with a one-way valve. A piston plate 420 is slidably connected in the piston cylinder 410, and a piston rod 411 is connected to the piston plate 420. The piston rod 411 reciprocates in the piston cylinder 410, and when the sliding stroke of the slider 310 increases in the direction away from the vertical plate 170, the sliding stroke of the piston rod 411 in the piston cylinder 410 increases synchronously.

[0058] The extraction pipe 430 is connected to the external water and fertilizer supply. The water and fertilizer are prepared by other equipment to ensure that they are used first, and the water and fertilizer are prepared according to the growth conditions of the medicinal materials on site. When fertilizing the medicinal materials, the piston rod 411 is controlled to move upward, so that the piston rod 411 drives the piston plate 420 to move upward synchronously, so that the piston cylinder 410 extracts the water and fertilizer through the extraction pipe 430. When the number of nozzles 140 opened increases, the upward movement distance of the piston rod 411 increases, thereby increasing the amount of water and fertilizer extracted. Then the piston rod 411 moves downward, so that the piston plate 420 moves downward and discharges the water and fertilizer extracted in the piston cylinder 410 through the supply pipe 370, and then sprays it out through the opened nozzle 140 to complete the fertilization of the medicinal materials.

[0059] Among the optional methods of this embodiment, the more preferred ones are:

[0060] The fertilizer amount adaptive adjustment mechanism 400 also includes a connecting rod 450, one end of which is hinged to the vertical plate 170, and the other end of the connecting rod 450 is connected to the piston rod 411. When the connecting rod 450 swings up, it drives the piston rod 411 to move up, and when the connecting rod 450 swings down, it drives the piston rod 411 to move down.

[0061] The end of the connecting rod 450 is hinged on the vertical plate 170 . When the connecting rod 450 swings, the piston rod 411 connected to the end of the connecting rod 450 can be pushed or pulled, so that the piston rod 411 can slide vertically in the piston cylinder 410 .

[0062] Among the optional methods of this embodiment, the more preferred ones are:

[0063] The top of the piston rod 411 is fixedly connected with a first sliding rod 440 . A through slot is formed on the connecting rod 450 . The first sliding rod 440 slides in the through slot of the connecting rod 450 .

[0064] The first slide bar 440 slides in the through groove of the connecting rod 450. When the connecting rod 450 swings upward, the first slide bar 440 can slide in the through groove of the connecting rod 450, thereby ensuring that the swing of the connecting rod 450 is not interfered with, and the piston cylinder 410 limits the piston rod 411 to ensure that the piston rod 411 does not tilt axially.

[0065] Among the optional methods of this embodiment, the more preferred ones are:

[0066] The output end of the active cylinder 320 is fixedly connected to the second sliding rod 330, and the second sliding rod 330 slides in the through groove of the connecting rod 450. When the slider 310 slides, it can drive the second sliding rod 330 to slide in the through groove of the connecting rod 450, so that the second sliding rod 330 is close to or away from the connection between the connecting rod 450 and the vertical plate 170, thereby driving the piston rod 411 to move different strokes when the active cylinder 320 extends and retracts the same stroke.

[0067] When the slider 310 slides in the direction away from the vertical plate 170, the active cylinder 320 moves synchronously. When the slider 310 moves away from the vertical plate 170, the number of activated nozzles 140 increases. At this time, it means that the height of the medicinal material is high, so it is necessary to increase the amount of water and fertilizer to irrigate the medicinal material. The second slide bar 330 at the output end of the active cylinder 320 that moves synchronously with the slider 310 slides in the through groove of the connecting rod 450 and can approach the swing point of the connecting rod 450. When the active cylinder 320 is shortened to the shortest, the second slide bar 330 drives the connecting rod 450 to swing to the same as the swing point. The slider 310 is parallel to the sliding direction. In this state, the slider 310 slides, so that when the second slider 330 slides in the through groove of the connecting rod 450, it will not drive the connecting rod 450 to swing further; after the second slider 330 approaches the swing point of the connecting rod 450, the active cylinder 320 can increase the upward swing angle of the connecting rod 450 when it is extended, so that the connecting rod 450 can drive the piston rod 411 to move upward. The distance increased, thereby increasing the extraction amount of water and fertilizer, ensuring that the spraying amount of water and fertilizer is suitable for medicinal materials with higher heights.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
