Description

Technical Field

[0001] The present invention relates to the technical field of tree fertilization, in particular to a fully automatic quantitative fertilization device for trees and a use method thereof. Background Art

[0002] Fertilization methods are divided into liquid fertilization and solid fertilization. Compared with liquid waste, solid fertilizers usually have a long-lasting effect. A single application can provide nutrients to trees for a longer period of time, reducing the frequency of fertilization. For example, the nutrients in organic fertilizers are gradually released, which can continuously improve the soil. Solid fertilization is generally done by trench application; trench application methods include ring trench application, strip trench application, radial trench application, and hole trench application; the ring trench application method refers to digging a circular trench around the outer circle of the tree, pouring in fertilizer, and then backfilling. It is suitable for trees of different ages.

[0003] A search revealed a patent application with publication number CN214507888U, titled "A Tree Fertilizer Device." This device utilizes a limiting ring placed around the tree's trunk to control the device's rotation around the tree, achieving circular fertilization. This fertilization method relies heavily on the tree itself and is unsuitable for young trees.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1 to 12 As shown, the present invention includes the following embodiments: Example 1: A fully automatic quantitative fertilization device for trees, comprising a storage box 1 with a shoulder strap 11 and a feed pump 12 at the bottom of the storage box 1; the feed pump 12 is connected to a feed pipe 13; the feed pipe 13 is fixedly connected to a fertilizing rod 2 at one end away from the feed pump 12; the fertilizing rod 2 is connected to a fertilizing ring 3 at its lower end; the fertilizing ring 3 is rotated by the drive of the fertilizing rod 2; a plurality of embedded parts 4 are evenly arranged on the lower surface of the fertilizing ring 3; the embedded parts 4 are composed of a top flat plate 41, an inner vertical plate 42, an outer vertical plate 43 and a bottom inclined plate 44; the bottom inclined plate 4 4 is arranged inclined, and the distance between the bottom inclined plate 44 and the top flat plate 41 is arranged to vary in the circumferential direction of the fertilizer ring 3; the inner vertical plate 42 is vertically fixed to the inner side of the upper surface of the bottom inclined plate 44; the outer vertical plate 43 is vertically fixed to the outer side of the upper surface of the bottom inclined plate 44; the upper ends of the inner vertical plates 42 and the outer vertical plates 43 are fixed to the lower surface of the top flat plate 41; the lower surface of the top flat plate 41 is fixed to the discharge pipe 45; the lower end of the discharge pipe 45 passes through the bottom inclined plate 44 and is flush with the lower surface of the bottom inclined plate 44; the upper end of the discharge pipe 45 is connected to the conveying pipe 13.

[0022] In this embodiment, the top flat plate 41, the inner vertical plate 42, the outer vertical plate 43 and the bottom inclined plate 44 enclose a burial cavity 46; the vertical space of the burial cavity 46 is arranged to vary around the fertilizing ring 3; the cross-section of the discharge pipe 45 is triangular; one of the edges of the discharge pipe 45 faces the soil inlet of the burial cavity 46.

[0023] Before fertilizing, the fertilizer worker puts the storage box 1 on his back with the strap 11, holds the fertilizer rod 2 and drives the fertilizer ring 3 to fertilize, then controls the fertilizer ring 3 to be put on the tree seedlings that need to be fertilized and falls on the ground, controls the fertilizer rod 2 to drive the fertilizer ring 3 to rotate, and a plurality of digging parts 4 are provided just below the fertilizer ring 3. The digging parts 4 rotate as the fertilizer ring 3 rotates, and the digging parts 4 perform circumferential movement during the contact with the ground. The bottom inclined plate 44 in the digging part 4 is obliquely inserted into the soil due to its own inclined state, thereby achieving the purpose of digging the soil. The soil in the burying cavity 46 is cut by one of the edges of the discharge pipe 45, so that the soil is loosened and continues to move in the burying cavity 46. During the process of the ground being dug by the bottom inclined plate 44, the fertilizer worker controls the feed pump 12 by pressing a button. The feed pump 12 will move the fertilizer in the storage box 1 along the feed pipe 13 through the fertilizer rod 2 and the fertilizer ring 3 into the discharge pipe 45, and finally flow out along the pipe mouth of the discharge pipe 45. The fertilizer flowing out of the feed pipe 45 will fall directly from the bottom inclined plate 44. As the fertilizing ring 3 continues to rotate, the burying member 4 will continue to excavate the soil. The new soil will enter the burying cavity 46, and the old soil in the burying cavity 46 will flow out from the excavation port in the burying cavity 46. The soil flowing out from the excavation port of the burying cavity 46 will bury the position where the fertilization is completed. Due to the restrictions of the inner vertical plate 42 and the outer vertical plate 43, the excavated soil will not be lost and can be collected for subsequent burial, which is more thorough. After completing the excavation, fertilization and burial of the soil, the soil is stopped. When the feed pump 12 stops working, the fertilizing ring 3 is controlled to rotate in the opposite direction. The digging and burying part 4 will rotate with the reverse rotation of the fertilizing ring 3. During the reverse rotation, the digging and burying part 4 will tilt out from the soil, and the fertilizing ring 3 is controlled to fall around the next tree seedling that needs to be fertilized, thereby completing the annular ditch fertilizing process of the trees in the seedling stage in sequence. In this embodiment, the fertilizing ring 3 rotates in the soil around the tree under the control of the fertilizing rod 2, so that the fertilizing device can quickly complete the soil excavation, fertilization and burying work for the trees in the seedling stage, making the tree fertilization operation more convenient and more efficient.

[0024] Example 2: The upper surface of the fertilizer ring 3 is provided with an annular groove 31; the main slider 5 and the auxiliary slider 6 are slidably connected in the annular groove 31; the main slider 5 is located directly above the fertilizer ring 3 and extends outward; a main groove 51 is provided inside the main slider 5; the lower end of the fertilizer rod 2 is provided with a rod groove 21; the rod groove 21 is spirally connected to the screw 7 in a sealed manner; the spiral groove 71 on the outer surface of the screw 7 is movably sealed with the rod block 22 on the inner wall of the rod groove 21; the main slider 5 is rotatably sealed and connected to the lower end of the screw 7; the screw 7 is located in the main groove 5 1 is connected to the upper end through a first hole 72; the upper end of the rod groove 21 is connected to the feed pipe 13; the outer wall of the upper end of the fertilizing rod 2 is fixedly connected to the handle 23; the upper end of the screw rod 7 is connected to the upper end of the rod groove 21 through an elastic member 24; the lower groove wall of the main groove 51 and the inner side of the annular groove 31 are connected through a second hole 52; the outer surface of the fertilizing ring 3 is provided with an annular tooth 32; the annular tooth 32 meshes with the gear 73; the gear 73 is fixedly connected to the lower end of the screw rod 7; the third hole 33 at the bottom of the annular groove 31 is connected to the discharge pipe 45.

[0025] In this embodiment, the elastic member 24 is a spiral elastic plate; the upper end of the elastic member 24 abuts against the upper end of the rod groove 21, and the lower end is fixedly connected to the upper end of the screw rod 7.

[0026] For some tree seedlings with higher vertical height, the space just above the fertilizing ring 3 is exposed. During the fertilizing process, the fertilizing ring 3 can be put on the tree seedling and dropped on the soil surface. Then, when stepping on the auxiliary slider 6, the pedaling force of the auxiliary slider 6 will be transmitted to the fertilizing ring 3 and finally to the digging and embedding part 4. The gripping handle 23 drives the fertilizing rod 2 to move downward. During the downward movement of the fertilizing rod 2, it will approach the main slider 5, and the distance from the upper end of the screw rod 7 to the upper end of the rod groove 21 will be reduced, so that the elastic member 24 in the rod groove 21 will be squeezed. During the downward movement of the fertilizing rod 2, the rod block 22 will be driven to move along the spiral groove 71 on the outer wall of the screw rod 7. Under the spiral transmission of the groove 71, the screw rod 7 will rotate, and the elastic member 24 will be driven to stir in the rod groove 21 during the rotation of the screw rod 7, so that the fertilizer in the rod groove 21 is loosened. The arc outer wall of the screw rod 7 near the lower end is smoothly set. The gear 73 will be driven to rotate during the rotation of the screw 7, and the annular gear 32 will be driven to engage the transmission during the rotation of the gear 73. In this way, the fertilizer ring 3 will rotate, and the annular groove 31 and the digging and embedding member 4 will be driven to rotate during the rotation of the fertilizer ring 3. Since the foot is stepped on the auxiliary slider 6, there is a large friction between the foot and the auxiliary slider 6, and the auxiliary slider 6 will not slip with the foot, so that the auxiliary slider 6 and the main slider 5 will slide with the annular groove 31. The fertilizer ring 3 rotates, and the excavating member 4 is driven to dig the soil during the rotation. When the soil is dug, the feeding pump 12 will work, and the feeding pump 12 will flow the fertilizer in the storage box 1 into the rod groove 21 along the feeding pipe 13. The fertilizer in the rod groove 21 will enter the main groove 51 along the first air hole, and the fertilizer in the main groove 51 will enter the annular groove 31 along the second hole 52. Then, the third hole 33 provided along the bottom of the annular groove 31 is connected with the discharge pipe 45. In this way, the fertilizer will flow from the third hole 33 at the bottom of the annular groove 31 into the discharge pipe 45, and finally flow out along the discharge pipe 45. The fertilizer flowing out of the discharge pipe 45 will fall into the dug soil. After the annular groove fertilization is completed, the force of the fertilizing rod 2 moving downward is reduced, and the elastic member 24 will push the fertilizing rod 2 to move upward. During the upward movement of the fertilizing rod 2, the rod block 22 will move again along the spiral groove 71, so that the screw rod 7 drives the gear 73 to rotate in the opposite direction. The gear 73 will drive the fertilizing ring 3 to rotate in the opposite direction through the annular gear 32. The fertilizing ring 3 rotating in the opposite direction will drive the digging part 4 to move in the opposite direction, so that the digging part 4 is moved out of the soil; in this embodiment, the outer side of the fertilizing ring 3 is driven by the fertilizing rod 2 and the screw rod 7, so that the space directly above the fertilizing ring 3 is exposed, thereby meeting the fertilization of some trees with higher seedlings and expanding the scope of application of the fertilizing device.

[0027] Example 3: The fertilizing ring 3 is composed of two fertilizing arcs 34; a torsion groove 35 is provided at the end of one of the fertilizing arcs 34; a torsion block 37 is rotatably connected to the torsion groove 35 through a torsion spring 36; and the torsion block 37 is fixedly connected to the end of the other fertilizing arc 34.

[0028] In this embodiment, two semi-annular strips 8 are connected in a rotating seal in the annular groove 31; when the fertilizing rod 2 and the screw rod 7 are in the unfolded state, the contact positions of the two semi-annular strips 8 correspond to the contact positions of the two fertilizing arcs 34; one of the semi-annular strips 8 is fixedly connected to the main slider 5, and the other semi-annular strip 8 is connected to the auxiliary slider 6; the cross-section of the semi-annular strip 8 is n-shaped; the second hole 52 passes through the semi-annular strip 8 at the lower end and extends to the inner side of the semi-annular strip 8.

[0029] When the screw rod 7 is at the extreme position away from the bottom of the rod groove 21, the position of the screw rod 7 in the rod groove 21 remains stable while the elastic member 24 is against the bottom of the rod groove 21, making it difficult for the screw rod 7 to rotate. The gear 73 remains stable as the screw rod 7 is stationary, so that the two fertilizing arcs 34 remain stable. The contact positions of the two fertilizing arcs 34 correspond to the contact positions of the two semi-annular bars 8. Then, the two fertilizing arcs 34 are opened, and one of the fertilizing arcs 34 overcomes the torsion spring 36 to drive the torsion block 37 to rotate in the torsion groove 35. The two fertilizing arcs 34 are away from one end of the torsion spring 36. After the two fertilizing arcs 34 are put on the main stem of the tree seedlings, a gap is formed by staggering, and then the two fertilizing arcs 34 are put on the main stem of the tree seedlings by using the gap. In this way, when some seedlings have more leaves, the original method of directly putting them on the tree from top to bottom is abandoned, so as to achieve the purpose of protecting the branches of the tree. After the two fertilizing arcs 34 are put on the main stem of the tree, the fertilizing arcs 34 are loosened, and the torsion spring 36 drives the two fertilizing arcs 34 to rotate and reset to form an integral fertilizing ring 3. Then, while stepping on the auxiliary slider 6, the fertilizing rod 2 is controlled to move downward. During the downward movement of the fertilizing rod 2, the screw rod 7 and the gear 73 are driven to rotate, and the rotation of the gear 73 drives As the fertilizing ring 3 rotates, the two semi-annular strips 8 rotate in the annular groove 31, so that the contact positions of the ends of the two fertilizing arcs 34 are staggered with the contact positions of the ends of the two semi-annular strips 8, so that the two fertilizing rings 3 are not easily separated and staggered again, thereby locking the two fertilizing rings 3. The fertilizer in the rod groove 21 will enter the inner side of the semi-annular strip 8 along the first hole 72, the main groove 51, and the second hole 52, and finally flow into the discharge pipe 45 along the third hole 33. After fertilization is completed, the fertilizing rod 2 will move up, and the reverse rotation of the screw 7 will drive the fertilizing ring 3 to rotate in the reverse direction, and the digging piece 4 will be removed from the soil. After the screw rod 7 and the fertilizing rod 2 are fully extended, the contact positions of the ends of the two fertilizing arcs 34 correspond to the contact positions of the ends of the two semi-annular bars 8 again, so that after the two fertilizing arcs 34 are unlocked, the torsion force of the torsion spring 36 can be overcome to stagger the two fertilizing arcs 34 away from one end of the torsion spring 36, thereby removing the fertilizing arc 34 from the main stem of the tree; this embodiment arranges the fertilizing ring 3 into two detachable and repositionable fertilizing arcs 34, so that it can be directly put on the tree from the main stem position of the tree without passing through the branches of the tree, thereby achieving the goal of protecting the tree while completing the fertilizing process of the tree.

[0030] Example 4: An n-shaped groove 81 is provided at the end of the semi-annular strip 8 connected to the auxiliary slider 6; an n-shaped block 82 is connected to the sliding seal in the n-shaped groove 81; an n-shaped card groove 83 is provided at the end of the semi-annular strip 8 connected to the main slider 5; the n-shaped block 82 can be snapped into the n-shaped card groove 83; an auxiliary groove 61 is provided in the auxiliary slider 6; the sliding seal in the auxiliary groove 61 is connected to the pedal plate 62; the upper surface of the pedal plate 62 is fixedly connected to the pedal block 64 through the pedal rod 63; the pedal block 64 is located above the auxiliary slider 6; the lower inner wall of the auxiliary groove 61 is connected to the bottom of the n-shaped groove 81 through the fourth hole 65; the upper groove wall of the auxiliary groove 61 is connected to the upper surface of the pedal plate 62 through a spring 66.

[0031] After the two fertilizing arcs 34 in the fertilizing ring 3 are staggered, the two fertilizing arcs 34 can be directly put on the main stem of the tree without passing through the branches of the tree. As the torsion spring 36 drives the two fertilizing arcs 34 to reset and re-form into a whole, the pedal block 64 moves downward, and the pedal block 64 will drive the pedal rod 63 to move downward during the downward movement of the pedal block 64, and the pedal rod 63 will drive the pedal plate 62 to move downward during the downward movement of the pedal plate 62. The pedal plate 62 divides the auxiliary groove 61 into an upper chamber and a lower chamber. The upper chamber is connected to the outside air, and the lower chamber is filled with liquid medium. When the pedal plate 62 moves downward, it will overcome the elastic force of the spring 66, and the lower chamber is After the pedal 62 moves downward and is squeezed, it enters the n-shaped groove 81 along the fourth hole 65 and pushes the n-shaped block 82. The n-shaped block 82 will be inserted into the n-shaped card slot 83 to achieve the locking and connection of the two semi-annular strips 8, so that the two fertilizing arcs 34 are locked, which makes the rotation of the fertilizing ring 3 more stable; when the pedal 62 is released, the spring 66 pushes the pedal 62 to move upward, the space in the lower cavity becomes larger and forms a negative pressure, and the n-shaped block 82 moves out of the n-shaped card slot 83 and retracts into the n-shaped groove 81, so that the two semi-annular strips 8 are unlocked, and the two fertilizing arcs 34 are also unlocked.

[0032] Example 5: The arc-shaped outer wall of the fertilizing ring 3 is provided with an adjustment groove 38; the adjustment groove 38 is slidingly sealed and connected to one end of the U-shaped tube 9; the other end of the U-shaped tube 9 is fixedly connected to the embedded part 4 and is connected to the discharge pipe 45; the adjustment groove 38 is connected to the bottom of the annular groove 31 through the third hole 33; the upper surface of the fertilizing ring 3 is provided with a stepped threaded hole 39 connected to the adjustment groove 38; the stepped threaded hole 39 is threadedly sealed and connected to a bolt 91; the bolt 91 is pressed against the outer wall of one end of the U-shaped tube 9.

[0033] The embedding part is adjustable in the radial direction of the fertilizing ring 3. Specifically, the bolt 91 is loosened to unlock one end of the U-shaped tube 9, and then one end of the U-shaped tube 9 is moved in the adjustment groove 38. The other end of the U-shaped tube 9 will drive the embedding part 4 to move closer to or away from the center of the fertilizing ring 3, changing the diameter of the annular groove fertilization to meet the fertilization needs of trees at different times. After completing the position adjustment of the embedding part 4, the bolt 91 is tightened so that the bolt 91 rests on the outer wall of one end of the U-shaped tube 9, so that the position of the embedding part 4 and the U-shaped tube 9 is locked.

[0034] Example 6: A method for using a fully automatic quantitative fertilization device for trees, the method being applicable to the fully automatic quantitative fertilization device for trees according to any one of claims 1 to 8, the method comprising the following steps: S1: After putting fertilizer into the storage box 1, the storage box 1 is carried on the body using the shoulder strap 11, and the fertilizer rod 2 is held to drive the fertilizer ring 3 close to the tree that needs to be fertilized; S2: Move the two fertilizing arcs 34 away from one end of the torsion spring 36 to separate and form a gap, and then put the two fertilizing arcs 34 on the main stem of the tree. The torsion spring 36 will drive the two fertilizing arcs 34 to return to the original position and form a whole. S3: While stepping on the pedal block 64, the fertilizing rod 2 is controlled to move downward. During the downward movement of the pedal block 64, the N-shaped block 82 is driven to engage in the N-shaped slot 83. During the downward movement of the fertilizing rod 2, the screw 7 is driven to rotate. During the rotation of the screw 7, the fertilizing ring 3 is driven to rotate via the gear 73. During the rotation of the fertilizing ring 3, the digging and burying part 4 is driven to rotate to dig and bury the soil. The feed pump 12 is driven to drive the discharge pipe 45 to discharge the material, completing the fertilizing process. S4: Loosen the fertilizing rod 2 and the pedal block 64.
