Description

Technical Field

[0001] The invention belongs to the technical field of fertilization equipment, and in particular relates to fertilization equipment for tea planting. Background Art

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. Tea ingredients include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages made from tea leaves are one of the three major beverages in the world; fertilizers are the food for the growth of tea trees and the material basis for increasing tea production and improving tea quality. Therefore, fertilization plays an important role in the growth of tea trees and the yield and quality of tea.

[0003] There are two types of fertilization for tea planting: root fertilization and foliar fertilization. Root fertilization can be divided into basal fertilizer and topdressing, while foliar fertilization is mainly used for topdressing. Since foliar fertilization is a supplement to root fertilization, the currently commonly used foliar fertilizers include seaweed foliar fertilizers, humus foliar fertilizers and chemical fertilizer foliar fertilizers such as 0.5% to 1% urea solution. Foliar fertilizer should be applied on cloudy days or in the evening, and should be sprayed on the back of the leaves.

[0004] Most of the existing fertilization equipment for tea planting is used to fertilize the roots of tea leaves, while for fertilizing the leaves of tea leaves, most tea farmers manually fertilize them using a back-type fertilizer bucket. In addition, since the tea leaves of tea trees are relatively dense, it is difficult to efficiently fertilize the back of the leaves of tea leaves. This fertilization method not only reduces the fertilization efficiency of large-scale tea gardens, but also affects the quality of tea topdressing. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] See also Figure 1-Figure 7 As shown, the present invention is a fertilization equipment for tea planting, comprising a liftable mobile vehicle 1, a fertilizer box 2 is installed on the flat plate of the mobile vehicle 1, a fertilizer bin 21 is provided at the lower part of the fertilizer box 2, and a mobile bin 22 is divided by a partition above the fertilizer bin 21, two long slide grooves 23 are provided on the partition between the fertilizer bin 21 and the mobile bin 22, at least two material guide bends 3 are vertically inserted in the fertilizer bin 21, and each material guide bend 3 passes upward through the long slide groove 23 and extends into the mobile bin 22, spray pipes 4 are slidably extended from the left and right side walls of the mobile bin 22, and each spray pipe 4 is respectively connected to the horizontal pipe of the extended material guide bend 3, and each spray pipe 4 is provided with a plurality of spray holes 41 in a circular array along its length direction, and a driving sliding mechanism 5 is installed in the mobile bin 22, and the driving sliding mechanism 5 is used to drive the spray pipe 4 to extend out of the fertilizer box 2;

[0030] In the scheme designed by the present invention, the present invention installs a fertilizer box 2 on a mobile vehicle 1 that can be raised and lowered. When it is necessary to fertilize the leaves of tea trees in the tea garden, the fertilizer solution is put into the fertilizer bin 21, and then the mobile vehicle 1 is pushed to move the fertilizer box 2 to the corresponding area where fertilization is required. At the same time, the height of the fertilizer box 2 can be adjusted according to the height of the tea trees. Then, the driving sliding mechanism 5 in the mobile bin 22 is controlled by the control panel on the mobile vehicle 1 to drive the left and right spray pipes 4 to extend outward synchronously in the mobile bin 22. At this time, the vertical pipe of the guide elbow 3 will slide horizontally in the long slide groove 23. When the spray pipe 4 is inserted into the leaf surface of the tea tree, the pump body in the fertilizer box 2 is controlled to work so that it can transport the fertilizer solution in the fertilizer bin 21 to the spray pipe 4 through the guide elbow 3. Since a plurality of spray holes 41 are opened on the outer tube wall of the spray pipe 4, the fertilizer solution will be evenly sprayed to the leaves through the plurality of spray holes 41. On the leaf surface of the tea tree, and because the spray pipe 4 is inserted into the leaf surface of the tea tree, the evenly sprayed fertilizer solution will be scattered on the back of the leaves, so that the leaf surface of the tea leaves can be efficiently fertilized, and the fertilizer will not be unable to be scattered on the dense back of the leaf surface because the tea leaves of the tea tree are relatively dense, and thus the effect of foliar topdressing of the tea leaves will not be affected. If the spray pipe 4 is only inserted into the surface leaf surface of the tea tree, the fertilizer applicator can push the mobile vehicle 1 to move forward continuously, so that the extended spray pipe 4 can move synchronously, so that the fertilizer application equipment can efficiently fertilize the tea leaves in the tea garden; and if the spray pipe 4 extends into the leaf surface below the tea tree, it is necessary to first retract the spray pipe 4 into the mobile bin 22, so that the spray pipe 4 is separated from the tea tree, and then push the mobile vehicle 1 forward to facilitate the spray pipe 4 to continue to extend and insert into the tea tree, so that the fertilizer application equipment can fertilize the tea leaves at different heights in the tea tree.

[0031] As an embodiment of the present invention, the driving sliding mechanism 5 includes a rotating shaft 51, a meshing gear 52, a belt transmission assembly 53, a guide slider 54 and a support frame 55. The top wall of the mobile warehouse 22 is rotatably mounted with at least three rotating shafts 51, and the lower end surface of each rotating shaft 51 extends into the mobile warehouse 22 and is fixed with a meshing gear 52. The three rotating shafts 51 extending from the top of the mobile warehouse 22 are connected by a belt transmission assembly 53. The two spray pipes 4 extending to the left and right are arranged along the axis of the rotating shaft 51. The two guide bend pipes 3 are symmetrically arranged, and the corresponding pipe walls of the symmetrical spray pipes 4 are provided with meshing teeth along the length direction thereof, and the meshing teeth are meshed with the meshing gears 52 for transmission. A guide slider 54 is fixedly sleeved on the vertical pipe walls of the two guide bend pipes 3, and the guide slider 54 is slidably arranged in the long slide groove 23. A support frame 55 is fixed on the outer side surface of the top of the guide slider 54, and the support frame 55 is slidably fitted to the upper surface of the lower warehouse wall of the mobile warehouse 22, and the width of the support frame 55 is greater than the width of the long slide groove 23;

[0032] In the scheme designed by the present invention, when the left and right spray pipes 4 need to be extended, the servo motor fixed above the fertilizer box 2 is controlled to work, so that it drives at least three equidistantly installed rotating shafts 51 to rotate through the belt transmission assembly 53, and the three meshing gears 52 located in the mobile bin 22 rotate. Since the meshing teeth provided on the corresponding pipe walls of the left and right spray pipes 4 are meshed and transmitted with the three meshing gears 52, the rotation of the meshing gears 52 will drive the two spray pipes 4 to slide and extend synchronously toward the left and right side walls of the fertilizer box 2, thereby facilitating the automatic insertion of the spray pipes 4 into the leaf surfaces of the tea trees on both sides of the fertilizer box 2, and the sliding of the spray pipes 4 will drive the vertical pipe of the guide bent pipe 3 to slide in the fertilizer bin 21, and the setting of the guide slider 54 can make the guide The vertical tube of the material bend pipe 3 slides stably and safely in the long slide groove 23, and can also play a role in sliding guidance for the spray pipe 4, and the support frame 55 on the guide slider 54 can play a role in gravity support for the material guide bend pipe 3, preventing the material guide bend pipe 3 from settling in the fertilizer bin 21, thereby affecting the stable and safe sliding out of the spray pipe 4. When the spray pipe 4 needs to be retracted into the mobile bin 22, the three meshing gears 52 rotate in the opposite direction to drive the meshing spray pipe 4 to automatically retract into the mobile bin 22, which not only makes it convenient for the mobile vehicle 1 to drive the fertilizer box 2 to move to the next row of tea trees for foliar fertilization, but also reduces the overall space occupied by the fertilization equipment, thereby facilitating the fertilization equipment to fertilize the leaves of tea leaves in tea gardens of different areas.

[0033] As an embodiment of the present invention, the spray pipe 4 is connected to the material guide elbow 3 through a connecting component, and the connecting component includes a connecting pipe 56, an externally threaded pipe 57 and a nut 58. One end of the connecting pipe 56 is connected to the tail end of the spray pipe 4, and the other end of the connecting pipe 56 is provided with a threaded hole. The mouth of the horizontal pipe of the material guide elbow 3 is rotatably sleeved with an externally threaded pipe 57, and the externally threaded pipe 57 is threaded into the threaded hole, and the tail end of the externally threaded pipe 57 is provided with a nut 58. In the scheme designed by the present invention, through the cooperation of the externally threaded pipe 57 and the nut 58, the fertilizer applicator can detachably install the horizontal pipe of the material guide elbow 3 into the threaded hole of the connecting pipe 56, and because the connecting pipe 56 is connected to the spray pipe 4, it is convenient to quickly connect and assemble the material guide elbow 3 with the spray pipe 4, and it is also convenient to disassemble and replace the spray pipe 4 that has been used for a long time or is damaged, and the pipe wall of the connecting pipe 56 is also provided with meshing teeth that mesh with the meshing gear 52.

[0034] As an embodiment of the present invention, the front and rear side walls of the fertilizer box 2 are respectively provided with a rotating spraying mechanism 6, and the rotating spraying mechanism 6 includes a rotating disk 61, a support frame 62, a sliding sleeve 63, a first adsorption ring 64, a metal ring 65, a second adsorption ring 66, a sliding ring 67 and a liquid guide hose 68. The left and right side walls of the fertilizer box 2 are provided with an annular cavity 24 at positions corresponding to the spraying pipe 4, and a rotating disk 61 is rotatably provided in the annular cavity 24. The inner side surface of the rotating disk 61 is connected to the output shaft of the servo motor through a rotating shaft, and the servo motor is fixedly supported in the mobile bin 22 through the support frame 62, and the rotating disk 61 is aligned with the spraying pipe 4. A sliding sleeve 63 is fixed, and a spray pipe 4 is slidably inserted in the sliding sleeve 63. A first adsorption ring 64 is fixed to the rear end of the sliding sleeve 63, and the rear end surface of the first adsorption ring 64 is evenly provided with electromagnetic adsorption blocks. A metal ring 65 is insulatedly sleeved at the tail end of the spray pipe 4. A second adsorption ring 66 is fixed to the pipe opening of the connecting pipe 56 aligned with the spray pipe 4, and a plurality of electromagnetic adsorption blocks are provided on the end surfaces corresponding to the second adsorption ring 66 and the metal ring 65. Sliding grooves 42 are provided in the spray pipe 4 and the connecting pipe 56, and sliding rings 67 are slidably provided in the two sliding grooves 42. The two sliding rings 67 are connected through a liquid guide hose 68.

[0035] In the scheme designed by the present invention, in order to increase the fertilization area of ​​the tea leaves by the atomized fertilizer solution sprayed by the spray pipe 4, therefore, when the continuously moving spray pipe 4 is completely extended out of the fertilizer box 2, the spray pipe 4 is disengaged from the meshing gear 52 close to the warehouse wall of the mobile warehouse 22, and the metal ring 65 at the rear end of the spray pipe 4 will fit with the first adsorption ring 64 on the rear end face of the sliding sleeve 63, and the principle of the electromagnetic adsorption block is the same as that of the electromagnetic suction cup, and then the electromagnetic adsorption block on the first adsorption ring 64 is energized so that the first adsorption ring 64 is magnetically adsorbed and connected with the metal ring 65, and the electromagnetic adsorption block on the second adsorption ring 66 on the connecting pipe 56 is de-energized and loses its magnetic adsorption force The connecting tube 56 is disconnected from the metal ring 65, and then the meshing gear 52 is controlled to rotate slowly in the opposite direction. At this time, the meshing gear 52 drives the connecting tube 56 to slide toward the center of the mobile bin 22, so that the pipe opening of the connecting tube 56 is pulled away from the pipe opening of the spraying tube 4 by a small distance. At this time, the two sliding rings 67 are respectively sealed and slid in the sliding grooves 42 opened on the connecting tube 56 and the spraying tube 4, so that the liquid guide hose 68 is exposed. Since the spraying tube 4 is fixed by adsorption with the sliding sleeve 63 on the rotating disk 61, and the spraying tube 4 is connected with the disconnected connecting tube 56 through the liquid guide hose 68, the servo motor will drive the spraying tube 4 to rotate through the rotating disk 61 when working, and since the servo motor It is fixedly supported in the mobile bin 22 by the vertical support frame 62. Therefore, the rotating disk 61 will not drive the spray pipe 4 to rotate 360 ​​degrees, but will only rotate counterclockwise or clockwise as needed. When the spray pipe 4 rotates, the liquid guide hose 68 will drive the sliding ring 67 to slide continuously in the sliding groove 42, so that it can play a role of soft connection between the rotating spray pipe 4 and the connecting pipe 56, so that the spray pipe 4 can rotate counterclockwise or clockwise when inserted into the leaf surface, thereby increasing the area of ​​the spray pipe 4 inserted into the dense leaf surface, thereby further increasing the area of ​​the spray hole 41 on the spray pipe 4 spraying the fertilizer solution, thereby further improving the fertilization. The efficiency of the equipment in fertilizing the leaves; and when the spraying pipe 4 needs to be retracted into the mobile bin 22, the rotating disk 61 is controlled to drive the spraying pipe 4 to rotate to the highest point, so that the tail end of the spraying pipe 4 is aligned with the pipe end of the connecting pipe 56, and then the connecting pipe 56 is driven to fit close to the tail end of the spraying pipe 4, and the second adsorption ring 66 is magnetically adsorbed to the metal ring 65, so that the first adsorption ring 64 loses its magnetic adsorption force and is separated from the adsorption and fixation of the metal ring 65, thereby connecting the spraying pipe 4 with the connecting pipe 56, and then the rotation of the three meshing gears 52 will drive the spraying pipe 4 to be retracted into the mobile bin 22, so that the fertilization equipment can continue to fertilize the leaves of the next row of tea leaves.

[0036] As an embodiment of the present invention, the top wall of the mobile bin 22 is provided with two T-shaped grooves 25 along its length direction, the outer tube wall of the connecting pipe 56 is provided with a semicircular connecting sleeve 69, and a T-shaped slider 691 is vertically fixed on the semicircular connecting sleeve 69, and the T-shaped slider 691 is slidably arranged in the T-shaped groove 25;

[0037] In the scheme designed by the present invention, when the spray pipe 4 slides out or retracts, the connecting pipe 56 will drive the T-shaped slider 691 to slide in the T-shaped slide groove 25, so that the T-shaped slider 691 can play the role of suspension support for the tail end of the spray pipe 4, and when the spray pipe 4 is in a rotating state, the T-shaped slider 691 can play the role of limiting support for the connecting pipe 56, preventing the torque generated when the spray pipe 4 rotates from acting on the connecting pipe 56 through the liquid guiding hose 68, which may easily cause the connecting pipe 56 to deviate or tilt, thereby affecting the meshing transmission between the inner tube wall of the connecting pipe 56 and the meshing gear 52; and the connection of the semicircular connecting sleeve 69 will not affect the normal meshing transmission between the connecting pipe 56 and the meshing gear 52.

[0038] As an embodiment of the present invention, a plurality of toggle rods 7 are installed on the vertical tube wall of the two material guide bends 3, and the plurality of toggle rods 7 are all located in the fertilizer bin 21, and a scraper 71 is installed on the outer wall of the bottom end tube mouth of the vertical tube of the material guide bend 3, and the scraper 71 is in contact with the bottom of the fertilizer bin 21; in the scheme designed by the present invention, when the vertical tube of the material guide bend 3 slides in the fertilizer bin 21, the detachable plurality of toggle rods 7 and the scraper 71 at the bottom will continuously slide and toggle in the fertilizer bin 21, so that the fertilizer solution in the fertilizer bin 21 can be stirred and scraped off to prevent the fertilizer solution from being stratified or precipitated in the fertilizer bin 21; and when the fertilizer bin 21 needs to be cleaned, the sliding of the material guide bend 3 will drive the scraper 71 to slide on the bottom of the fertilizer bin 21, so that the fertilizer solution adhering to or precipitated on the bottom of the fertilizer bin 21 can be scraped off and cleaned.

[0039] As an embodiment of the present invention, a feeding pipe 8 is installed on the right side of the fertilizer box 2, and a sealing plug is installed on the feeding pipe 8, and an inspection door 9 is installed on the front side wall of the fertilizer bin 21; in the scheme designed by the present invention, the fertilizer applicator opens the sealing plug and can add fertilizer into the fertilizer bin 21 through the feeding pipe 8, and the installation of the glass inspection door 9 can observe the amount of fertilizer solution in the fertilizer bin 21 in real time, and at the same time, the parts in the fertilizer bin 21 can be inspected, disassembled and replaced.

[0040] As an embodiment of the present invention, a protective cover 10 is installed on the top of the fertilizer box 2, and the protective cover 10 is used to cover and protect the belt drive assembly 53; in the design of the present invention, the installation of the protective cover 10 can protect electrical components such as the belt drive assembly 53 above the fertilizer box 2.

[0041] Working principle:

[0042] When it is necessary to fertilize the leaves of the tea trees in the tea garden, the fertilizer solution is put into the fertilizer bin 21, and then the mobile vehicle 1 is pushed to move the fertilizer bin 2 to the area corresponding to the need for fertilization. At the same time, the height of the fertilizer bin 2 can be adjusted according to the height of the tea trees, and then the driving sliding mechanism 5 in the mobile bin 22 is controlled to work through the control panel on the mobile vehicle 1. At this time, the servo motor fixed above the fertilizer bin 2 is controlled to work, so that it drives at least three equidistantly installed rotating shafts 51 to rotate through the belt transmission assembly 53, and the three meshing gears 52 located in the mobile bin 22 rotate. Since the meshing teeth on the corresponding pipe walls of the left and right spray pipes 4 are meshed with the three meshing gears 52 for transmission, the rotation of the meshing gears 52 will drive the two spray pipes 4 to slide out synchronously toward the left and right side walls of the fertilizer bin 2, thereby facilitating the automatic insertion of the spray pipes 4 into the leaf surfaces of the tea trees on both sides of the fertilizer bin 2. When the spray pipes 4 are inserted into After the leaves of the tea trees are inside, the pump body in the fertilizer box 2 is controlled to work, so that the fertilizer solution in the fertilizer bin 21 is transported to the spray pipe 4 through the guide elbow 3. Since a plurality of spray holes 41 are provided on the outer wall of the spray pipe 4, the fertilizer solution is sprayed evenly onto the leaves of the tea trees through the plurality of spray holes 41. Moreover, since the spray pipe 4 is inserted into the leaves of the tea trees, the evenly sprayed fertilizer solution is scattered on the back of the leaves, thereby enabling efficient fertilization of the leaves of the tea leaves. When the spray pipe 4 needs to be retracted into the mobile bin 22, the three meshing gears 52 rotate in the opposite direction at this time, so that the meshing spray pipe 4 is automatically retracted into the mobile bin 22, which is not only convenient for the mobile vehicle 1 to drive the fertilizer box 2 to move to the next row of tea trees for foliar fertilization, but also can reduce the overall space occupied by the fertilization equipment, thereby facilitating the fertilization equipment to fertilize the leaves of the tea leaves in tea gardens of different areas.
