Description

Technical Field

[0001] The invention relates to the technical field of crop fertilization, and in particular to a portable fertilization device for crop protection. Background Art

[0002] The purpose of fertilization is to provide crops with nutrients and promote growth. If the soil can fully supply the various nutrients required by the plants, fertilization is not necessarily necessary. However, in general, soil fertility is often insufficient, so fertilization becomes an indispensable part of cultivation management.

[0003] At present, when fertilizing crops, fertilizers are usually sprinkled manually next to the crops, especially for tree crops, such as Chinese toon trees. This method of fertilization is prone to uneven fertilization, and due to the growth of weeds, the nutrients in the fertilizer are easily absorbed by weeds. In addition, there is also the problem of uneven spreading of fertilizers by hand. After the fertilizers are spread, the fertilizers are directly on the soil. Without the assistance of water, the fertilizers are less likely to be absorbed by crops. If the fertilizers are buried directly on one side of the root of the crop, it is easy to cause uneven fertilizer absorption, thereby reducing the efficiency of fertilizer absorption and utilization.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The following embodiments are demonstrated by taking fertilization of tree crops such as Chinese toon trees as an example: Reference Figure 1-Figure 8 A portable fertilizing device for crop protection comprises a fertilizer box 1, a movable plate 2 is movably installed on one side of the fertilizer box 1, a rotating belt 4 is movably installed on the bottom of the fertilizer box 1, a plurality of soil turning blades 5 are installed on the outer side of the rotating belt 4, a discharge port 3 is provided through the bottom of the fertilizer box 1, a material blocking mechanism is provided on the top of the discharge port 3, two first slots 18 are horizontally provided on the side of the movable plate 2 away from the fertilizer box 1 along the length direction of the movable plate 2, and the two first slots 18 are symmetrical along the length direction of the movable plate 2, a fixed slider 19 is slidably installed inside the first slot 18, and an auxiliary stabilizing mechanism is connected to the side of the fixed slider 19 away from the first slot 18, a connecting piece 36 is movably installed on the top of the movable plate 2, and a handle 37 is hingedly installed inside the connecting piece 36, and electric telescopic columns 15 are vertically installed on both sides of the bottom of both ends of the fertilizer box 1, the output end of the electric telescopic column 15 is downward, and the output end of the electric telescopic column 15 is connected to a universal wheel 16. The device is fixed on the tree trunk through an auxiliary stabilizing mechanism, and then the driving motor at the end of the rotating belt 4 drives the rotating belt 4 to rotate. Under the rotation of the rotating belt 4, the device makes a circular motion around the tree, and the turning blade 5 on the rotating belt plate 4 can turn the soil and turn the grass roots outward to complete the weed removal work around the tree. Then, the material blocking mechanism is controlled to make the discharge port 3 evenly spread the fertilizer downward.

[0023] As a technical optimization scheme of the present invention, two trapezoidal grooves 6 are vertically opened at the bottom of one side of the movable plate 2 close to the fertilizer box 1, and the two trapezoidal grooves 6 are symmetrical along the length direction of the movable plate 2, and a plug-in block 7 is installed inside the trapezoidal groove 6, and the plug-in block 7 is connected to the fertilizer box 1 on the side close to the fertilizer box 1. Some trees are prone to grow side buds on the main trunk. If the side buds are not cleaned in time, it will not only affect the growth of the trees, but also require special staff to prune them in the later stage, which is extremely wasteful of manpower and material resources. At this time, the staff holds the handle 37 to lift the movable plate 2 upward, and the plug-in block 7 slides in the trapezoidal groove 6. At this time, the second blade 26 on the arc plate 24 can easily prune the side buds on the trees during the process of lifting the movable plate 2.

[0024] As a technical optimization solution of the present invention, a rotating motor 12 is embedded and installed at the bottom of the fertilizer box 1, and the output end of the rotating motor 12 faces the rotating belt 4, and the output end of the rotating motor 12 is connected to the top of the rotating belt 4. The rotating belt 4 is driven to rotate by the rotating motor 12, and the inclination angle of the rotating belt 4 at the bottom of the fertilizer box 1 is adjusted, so that the rotating belt 4 has different functions under different use conditions, thereby improving the convenience of operation of the device.

[0025] As a technical optimization solution of the present invention, the material blocking mechanism includes a material blocking plate 13 and an electric push rod 14. The material blocking plate 13 is placed above the material outlet 3. A plurality of electric push rods 14 are connected to one side of the material blocking plate 13. The output end of the electric push rod 14 is away from the material blocking plate 13. The output end of the electric push rod 14 is connected to the inner wall of the fertilizer box 1. Inclined plates 17 are installed at the four corners of the bottom of the fertilizer box 1. The electric push rod 14 pushes the material blocking plate 13 to move, thereby controlling the size of the opening of the material outlet 3 and realizing the control of the material discharge speed.

[0026] As a technical optimization solution of the present invention, a screw rod 20 is installed inside the first slot 18 in a rotatable manner along the length direction. The ends of the two screw rods 20 that are away from each other are movable through the end wall of the first slot 18 and extend to the outside of the first slot 18. The screw rod 20 also penetrates the fixed slider 19. The penetration of the fixed slider 19 is connected to the screw rod 20 through a thread. The ends of the two screw rods 20 that are away from each other are installed with a handle. The movement of the fixed slider 19 is controlled by rotating the screw rod 20, and the position of the arc plate 24 is adjusted to adapt to trees of different sizes.

[0027] As a technical optimization scheme of the present invention, the auxiliary stabilization mechanism includes a first support rod 21, a connecting block 23 and an arc plate 24. The first support rod 21 is connected to the side of the fixed slider 19 away from the first slot 18. The second support rod 22 is movably inserted and installed inside the first support rod 21. A plurality of first openings 27 are evenly penetrated through the top of the first support rod 21 along the length direction. A first positioning pin 28 is movably penetrated and installed on the top of one end of the second support rod 22 close to the bottom end of the inner wall of the first support rod 21. The first positioning pin 28 can pass through the second support rod 22 through the first opening 27 and be inserted into the bottom of the first opening 27. The end of the second support rod 22 away from the first support rod 21 is connected to the connecting block 23, and an arc plate 24 is movably installed at one end of the two connecting blocks 23 close to each other. A plurality of balls 25 are horizontally movably embedded and installed on one side of the two arc plates 24 close to each other. The tree trunk is clamped by the arc plate 24, and then the device can be rotated while being fixed by the rotation of the ball 25. The insertion position in the different first openings 27 on the first support rod 21 is changed by the first positioning pin 28, so that the device can be quickly adjusted when facing trees of different sizes, thereby increasing the convenience of use of the device.

[0028] As a technical optimization scheme of the present invention, the ends of the two connecting blocks 23 close to each other are both penetrated with a second opening 29 along the length direction, and a connecting rod 31 is installed inside the second opening 29. The end of the connecting rod 31 close to the arc plate 24 is connected to the arc plate 24, and the other end of the connecting rod 31 extends to the outside of the second opening 29 and is connected to a first fixing plate 32. The side of the first fixing plate 32 away from the arc plate 24 is penetrated with a second fixing plate 33, and the side of the second fixing plate 33 close to the connecting rod 31 is horizontally installed with a positioning slider 34 along the length direction. The first fixing plate 32 is penetrated with a third slot 35 at the same horizontal height of the positioning slider 34. The connecting block 23 is penetrated with a second slot 30 along the length direction of the positioning slider 34 on the side away from the second support rod 22 and the bottom, and the positioning slider 34 can be slidably installed into the inside of the second slot 30. When the device is not in use, the second fixed plate 33 is pulled out and then the arc plate 24 is rotated so that the second blade 26 on the arc plate 24 is rotated to face the movable plate 2 to prevent accidental injury to personnel. At the same time, the device can also reduce the space occupied by the device, which is convenient for storage. The positioning slider 34 is engaged in the second slot 30, which can make the device fix the arc plate 24 more stably.

[0029] As a technical optimization solution of the present invention, a second blade 26 is installed on the top of the arc plate 24, and the shape of the second blade 26 matches the arc plate 24. A soil turning rake 8 is installed on one side of the bottom of the fertilizer box 1, and the height of the soil turning rake 8 is less than the rotating belt 4. The side buds on the tree trunk are trimmed by the second blade 26. During the rotation of the device, the soil turning rake 8 can level and break the soil turned by the rotating belt 4, making the soil softer and easier to absorb fertilizer. At the same time, the soil turning rake 8 can scrape all the grass roots in the soil to one position, which is convenient for the staff to clean up the weeds later. When spreading fertilizer, the soil turning rake 8 can make the fertilizer and soil mixed more fully, which is conducive to the absorption of fertilizer by trees.

[0030] As a technical optimization solution of the present invention, a first chute 9 is horizontally opened at the bottom of the side of the movable plate 2 away from the fertilizer box 1 along the length direction, a first electric slider 10 is slidably installed inside the first chute 9, and a first blade 11 is horizontally installed on the side of the first electric slider 10 away from the first chute 9. During the rotation of the device, the first electric slider 10 slides in the first chute 9, so that the first blade 11 extends outward, and the first blade 11 cuts the weeds from the bottom of the weeds.

[0031] As a technical optimization solution of the present invention, a third opening 38 is vertically opened in the middle section of the top of the movable plate 2, and a rotating rod 40 is rotatably installed inside the third opening 38 through a bearing, and the top of the rotating rod 40 is connected to the bottom of the connecting member 36, and the connecting member 36 can be rotated on the top of the movable plate 2 through the rotating rod 40. Two fifth openings 41 are horizontally penetrated through the middle section of the outer side of the rotating rod 40, and the two fifth openings 41 are in a vertical position relationship. A fourth opening 39 is horizontally opened along the end wall direction of the movable plate 2 on the side of the movable plate 2 away from the fertilizer box 1. The fourth opening 39 can be plugged and installed with a second positioning pin 42, and the second positioning pin 42 can penetrate the fifth opening 41 at the same time. The second positioning pin 42 is plugged into the fourth opening 39 and the fifth opening 41 to complete the fixing of the connecting member 36. When the connecting member 36 needs to be rotated, only the second positioning pin 42 needs to be pulled out to rotate the connecting member 36, so that the handle 37 can achieve different use effects under different use states. Inserting the second positioning pin 42 can limit the rotation of the connecting member 36, so that it can withstand greater tension in a fixed state.

[0032] When the present invention is in use, all electrical equipment of the device outputs electricity through the storage battery installed outside the device, and a cover plate (not shown in the figure) for blocking the top of the fertilizer box 1 is installed on the top of the fertilizer box 1 through a hinge; when the device is moved, it is only necessary to extend the electric telescopic column 15 downward to make the rotating belt 4 leave the ground, and then pull out the second positioning pin 42 so that the handle 37 can rotate freely. Then the staff completes the movement of the device by pulling the handle 37 by hand and the universal wheel 16 rolls on the ground, and the operation of the handle 37 when changing the working form is more convenient.

[0033] When the device needs to fertilize the trees, the staff will turn the handle by hand, so that the fixed slider 19 moves in the first slot 18 through the rotation of the screw rod 20, and then the two arc plates 24 clamp the trees. When the arc plates 24 clamp the trees, since the two arc plates 24 are rotated and installed with multiple balls 25 on the side close to each other, the arc plates 24 can make circular motion around the trunk through the balls 25 without causing significant wear on the trunk. Start the rotating motor 12, so that the rotating belt 4 starts to rotate and adjust the angle, and finally the length direction of the rotating belt 4 is offset from the length direction of the fertilizer box 1 by a certain angle (which can be as shown in the figure). Figure 8 The specific offset angle can be freely adjusted according to the use requirements, and multiple offset angles can be adjusted during use.

[0034] When in use, the fertilizer box 1 is filled with the required fertilizer in advance. At this time, the fertilizer box 1 has a certain weight, and the electric telescopic columns 15 are appropriately retracted. The two electric telescopic columns 15 close to the trunk can be retracted a little more, so that the fertilizer box 1 is slightly inclined toward the trunk, and the rotating belt 4 can contact the root ground more fully. Then start the rotating belt 4, and manually pull the handle 37 to drive the fertilizer box 1 to move. During the rotation of the rotating belt 4, since the arc plate 24 fixes the device on the trunk, the soil turning blade 5 on the rotating belt 4 can turn the soil on the surface of the tree root under the rotation of the rotating belt 4, and since the rotating belt 4 and the fertilizer box 1 are adjusted to a certain deflection angle, the soil turning blade 5 can turn the soil while the soil turning blade 5 turns the soil, and the device can make a circular motion around the trunk.

[0035] During the rotation of the device, the first electric slider 10 slides in the first slide groove 9, so that the first blade 11 extends outward. At this time, during the rotation of the device, the first support rod 21 can press down the relatively high weeds, and then the first blade 11 cuts the weeds from the bottom of the weeds, and then combines the soil turning effect of the rotating belt 4 to turn out the grass roots to complete the weed cleaning. During the rotation of the device, the soil turning rake 8 can level and break the soil turned by the rotating belt 4, making the soil softer and easier to absorb fertilizer. At the same time, the soil turning rake 8 can scrape all the grass roots in the soil to one position, which is convenient for the staff to clean the weeds later. The bottom of the soil turning rake 8 is higher than the bottom of the rotating belt 4, and does not affect the normal rotation of the rotating belt 4 during use.

[0036] After the weeds and soil around the trees are cleaned and turned over, the staff controls the electric push rod 14 through the preset switch to push the baffle plate 13 to move, so that the discharge port 3 is opened, and then the fertilizer in the fertilizer box 1 can be spread from the discharge port 3 to the soil. The distance of the baffle plate 13 can also be controlled to control the discharge speed. When spreading fertilizer, the soil rake 8 and the rotating belt 4 can make the fertilizer and soil mix more fully, which is conducive to the absorption of fertilizer by the trees. During the fertilizer spreading process, the device continues to rotate around the tree trunk, so that the fertilizer is spread while turning the soil and mixing and covering, so that the fertilizer is spread more evenly.

[0037] Before or during fertilization of trees, some trees tend to grow side buds on the roots of their main trunks. If the side buds are not cleaned up in time, it will not only affect the growth of the trees, but also require special staff to prune them in the later stage, which is a great waste of manpower and material resources. At this time, the staff holds the handle 37 to lift the movable plate 2 upward. At this time, the second blade 26 on the arc plate 24 can prune the side buds on the roots of the trees very easily during the process of lifting the movable plate 2.

[0038] When it is necessary to fertilize the crops planted in rows, the rotating motor 12 is used to drive the rotating belt 4 to rotate and adjust the angle so that the rotating belt 4 rotates to be consistent with the width direction of the fertilizer box 1. At this time, the electric telescopic column 15 is extended so that the bottom of the fertilizer box 1 is higher than the rows of crops. The handle 37 is pulled to move the device forward, and then the baffle plate 13 is opened to complete the fertilization of the rows of crops.

[0039] The device can also be used to fertilize other types of trees and has a wide range of adaptability.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
