Description

Technical Field

[0001] The invention relates to the technical field of fruit tree fertilization, and in particular to an improved fertilization device for a hilly orchard and a use method thereof. Background Art

[0002] Most fruit trees are planted in hilly and mountainous areas. In the process of fruit tree planting, the fruit trees need to be fertilized. The early fertilization of fruit trees is a key operation link in fruit tree production. It plays a vital role in the growth of fruit trees and the quality and yield of the fruits they produce. The fertilizers applied to fruits mainly include organic fertilizers and inorganic fertilizers. Generally, fertilizers are applied to the soil through fertilization devices to facilitate absorption by the root hairs of fruit trees.

[0003] At present, some handheld fertilizer devices use fixed-point fertilization to fertilize fruit trees. The fertilizer is mainly applied at the same depth. Although most of the root hairs of fruit trees are at a deep depth, fertilizing only at a deep depth may affect its absorption efficiency. In addition, if multiple fertilizations are used to achieve fertilization at different depths, it may affect its fertilization efficiency. In addition, the use of a plug-in fertilizer device for fertilization will result in drilling holes. If the soil is not covered separately, the fertilizer may decompose quickly and affect the absorption of the fruit trees. Summary of the invention

[0008] In order to facilitate the supply of fertilizer, the fertilization assembly further includes a connecting tube fixedly arranged on the drill rod, one end of the connecting tube is sealed and slid in the hollow shaft, the upper end of the connecting tube is provided with a supply tube, a movable tube is provided in the rotating tube, the lower end of the movable tube is symmetrically fixedly connected with a diversion tube, and the diversion tube matches the fertilization port, a first connecting plate is symmetrically fixedly connected in the rotating tube, a second connecting plate is symmetrically fixedly connected on the movable tube, and an electric telescopic rod is fixedly connected between the first connecting plate and the second connecting plate.

[0009] Preferably, a sealing plate is provided in the fertilizer application port for sealing and rotation, and a soft film is fixedly connected between the sealing plate and the conical head.

[0010] In order to facilitate the sealing of the fertilizer application port, preferably, a plurality of elastic ropes are fixedly connected between the lower end of the sealing plate and the conical head, and when the moving tube moves downward, the diverter tube squeezes the sealing plate to open the lower end of the sealing plate.

[0011] In order to facilitate driving the moving plate to move, the driving assembly further includes a push rod rotatably arranged on the moving plate, the upper end of the push rod is rotatably connected to the moving tube, and the push rod is tilted.

[0012] In order to facilitate accurate detection of the depth of the conical head, further, a fixed ring is fixedly connected to the drill rod, a sliding ring is slidably provided at the lower end of the drill rod, a spring is fixedly connected between the fixed ring and the sliding ring, a first locator is fixedly connected inside the sliding ring, and a second locator is fixedly connected inside the conical head.

[0013] In order to improve the soil covering effect, further, the two movable plates are both inclined.

[0014] In order to facilitate the blocking of the shunt pipe, the lower end of the shunt pipe is further provided with an inclined opening, and the lower end of the shunt pipe is fitted with a sealing plate, the sealing plate is symmetrically fixedly connected with side plates, and the lower end of the sealing plate is fixedly connected with a baffle.

[0015] A method for using a hilly orchard improved fertilization device mainly comprises the following steps:

[0016] Step 1: Hold the handheld rod and press the drill rod down into the soil at the point where fertilizer is to be applied;

[0017] Step 2: The driving assembly drives the moving plate to slide, the moving plate drives the plug rod to extend, and the rotating rotating tube drives the plug rod to rotate along the axis of the drill rod;

[0018] Step 3: Pull the hand-held rod upward to move the drill rod upward, and supply fertilizer into the soil at different depths through the fertilization assembly, and loosen the soil to cover the fertilizer.

[0019] Compared with the prior art, the present invention provides an improved fertilization device for hilly orchards, which has the following beneficial effects:

[0020] 1. The improved fertilization device for hilly orchards drives the rotating tube and the conical head to rotate through the first gear and the second gear. At this time, the rotating conical head drives the insert rod to rotate along the axis of the drill rod. The insert rod breaks up the soil to fill the drill hole squeezed out by the drill rod. When the fertilization port moves to a certain depth, the fertilizer is supplied to the soil through the fertilization port by the fertilization component, and the soil broken up by the insert rod is covered. When the fertilization port reaches another depth, the fertilization component spreads the fertilizer through the fertilization port again, so that fertilization at different depths can be achieved at a time, which effectively improves the efficiency of fertilizing fruit trees, and can ensure that there is soil separation between fertilizers at different depths, which is convenient for the absorption of the fruit tree roots. At the same time, the method of breaking up and covering the soil with the insert rod can prevent the waste caused by the excessive decomposition of solid fertilizers, and can effectively improve the absorption effect of the root system.

[0021] 2. The improved fertilization device for hilly orchards controls the electric telescopic rod to extend through a controller, and the electric telescopic rod drives the moving tube to move downward. The moving tube pushes out the moving plate through a push rod, and the moving tube moving downward drives the shunt tube to move downward. The shunt tube squeezes the sealing plate to open the sealing plate, and sends a signal to the controller through the button on the handheld rod. The controller controls the quantitative feeder to supply the fertilizer in the backpack fertilizer storage box into the hollow shaft, and then enters the shunt tube through the moving tube, and finally discharges the fertilizer through the shunt tube, thereby realizing fertilization operations at different depths. The conical head is blocked by the sealing plate, which is convenient for the drill rod to be inserted into the soil, and at the same time effectively prevents the soil from blocking the fertilization port and affecting fertilization.

[0022] 3. The improved fertilization device for hilly orchards is used to disperse the soil when the sliding moving plate carries multiple insertion rods and rotates along the axis of the drill rod. Figure 8 and Fig. 9 The cone head rotates clockwise to drive the moving plate to rotate clockwise, and multiple inclined inserted rods push the loosened soil downward so that it can cover the gap at the end of the cone head, thereby effectively improving its soil covering effect.

[0023] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The present invention can realize fertilization at different depths in a single time, effectively improving the efficiency of fertilizing fruit trees and facilitating the absorption of the roots of fruit trees. At the same time, the soil is broken up and covered by inserting rods to prevent solid fertilizers from decomposing too quickly and causing waste, and at the same time can effectively improve the absorption effect of the roots.

DETAILED DESCRIPTION

[0034] 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.

[0035] Example 1: Reference Figure 1-Figure 9 , an improved fertilization device for a hilly orchard, comprising: a drill rod 1, and also comprising: a hand-held rod 101, symmetrically fixedly connected to the upper end of the drill rod 1; a rotating tube 2, rotatably arranged in the drill rod 1; a conical head 203, fixedly arranged on the lower side of the rotating tube 2; a moving plate 401, symmetrically slidably arranged in the conical head 203; a plurality of insertion rods 402, fixedly arranged on the moving plate 401, and the insertion rods 402 are sealed and slidably connected to the conical head 203; a driving component for driving the moving plate 401 to move; a fertilizer port 3, symmetrically opened on the conical head 203; and a fertilization component for fertilizing from the fertilizer port 3.

[0036] A first gear 104 and a motor 103 are fixedly connected to the upper side of the drill rod 1, the output end of the motor 103 is fixedly connected to the first gear 104, a hollow shaft 201 is fixedly connected to the rotating tube 2, a second gear 202 meshing with the first gear 104 is fixedly connected to the hollow shaft 201, a plurality of buttons 102 are arranged on the hand-held rod 101, and a controller 105 is fixedly connected to the upper end of the drill rod 1.

[0037] When fertilizing the fruit trees, first hold the hand-held rod 101 and press down the drill rod 1, so that the drill rod 1 is inserted into the soil at the fertilization point next to the fruit tree, and the insertion depth of the drill rod 1 is greater than the maximum fertilization depth of more than fifteen centimeters. After the drill rod 1 is completely inserted into the soil, the drill rod 1 is pulled out upwards by the hand-held rod 101. Before pulling out the drill rod 1, the driving assembly is used to drive the moving plate 401 to slide out with the insertion rod 402, and a signal is transmitted to the controller 105 through the button 102. The controller 105 controls the motor 103 to rotate, and the motor 103 drives the rotating tube 2 and the conical head 203 to rotate through the first gear 104 and the second gear 202. At this time, the rotating conical head 203 drives the insertion rod 402 to slide along the drill rod 1. The axis rotates, and the rod 402 breaks up the soil to fill the drill hole squeezed out by the drill rod 1. When the fertilization port 3 moves to a certain depth, the fertilizer is supplied to the soil through the fertilization port 3 by the fertilization component, and is covered with the soil broken up by the rod 402. When the fertilization port 3 reaches another depth, the fertilization component again spreads the fertilizer through the fertilization port 3, so that fertilization at different depths can be achieved in a single time, which effectively improves the efficiency of fertilizing fruit trees and ensures that there is soil separation between fertilizers at different depths, which is convenient for the absorption by the roots of the fruit trees. At the same time, the rod 402 is used to break up and cover the soil to prevent the solid fertilizer from decomposing too quickly and causing waste, and at the same time can effectively improve the absorption effect of the roots.

[0038] Example 2: Reference Figure 1-Figure 9 , an improved fertilization device for hilly orchards, which is basically the same as Example 1, and further, the fertilization assembly includes a connecting pipe 106 fixedly arranged on the drill rod 1, one end of the connecting pipe 106 is sealed and slid in the hollow shaft 201, the upper end of the connecting pipe 106 is provided with a supply pipe 107, a moving pipe 207 is provided in the rotating tube 2, the lower end of the moving pipe 207 is symmetrically fixedly connected with a shunt pipe 208, and the shunt pipe 208 matches the fertilization port 3, a first connecting plate 204 is symmetrically fixedly connected in the rotating tube 2, a second connecting plate 205 is symmetrically fixedly connected on the moving pipe 207, and an electric telescopic rod 206 is fixedly connected between the first connecting plate 204 and the second connecting plate 205.

[0039] One end of the supply pipe 107 away from the connecting pipe 106 is connected to a fertilizer supply mechanism, wherein the fertilizer supply mechanism may be, but is not limited to, a backpack-type fertilizer storage box commonly used currently, wherein a quantitative feeder is provided between the backpack-type fertilizer storage box and the supply pipe 107 .

[0040] A sealing plate 301 is provided in the fertilizer application port 3 for sealing and rotation, and a soft film 302 is fixedly connected between the sealing plate 301 and the conical head 203 .

[0041] A plurality of elastic ropes 305 are fixedly connected between the lower end of the sealing plate 301 and the conical head 203. When the moving tube 207 moves downward, the diverter tube 208 squeezes the sealing plate 301 to open the lower end of the sealing plate 301.

[0042] The driving assembly includes a push rod 403 rotatably disposed on the moving plate 401 , the upper end of the push rod 403 is rotatably connected to the moving tube 207 , and the push rod 403 is tiltedly disposed.

[0043] Refer to Figure 7 and Figure 8 When the drill rod 1 is pulled out upward, the controller 105 is used to control the electric telescopic rod 206 to extend, and the electric telescopic rod 206 drives the moving tube 207 to move downward. The moving tube 207 pushes out the moving plate 401 through the push rod 403, and the moving tube 207 moving downward drives the shunt tube 208 to move downward, and the shunt tube 208 squeezes the sealing plate 301 to open the sealing plate 301. The button 102 on the hand-held rod 101 sends a signal to the controller 105, and the controller 105 controls the quantitative feeder to supply the fertilizer in the backpack fertilizer storage box into the hollow shaft 201, and then enters the shunt tube 208 through the moving tube 207, and finally discharges the fertilizer through the shunt tube 208, thereby realizing fertilization operations at different depths, and the conical head 203 is blocked by the sealing plate 301, which is convenient for the drill rod 1 to be inserted into the soil, and at the same time effectively prevents the soil from blocking the fertilizer port 3 and affecting fertilization.

[0044] Example 3: Reference Figure 1-Figure 9, an improved fertilization device for hilly orchards, is basically the same as Example 1, and further, a fixed ring 108 is fixedly connected to the drill rod 1, a sliding ring 109 is slidably provided at the lower end of the drill rod 1, a spring 110 is fixedly connected between the fixed ring 108 and the sliding ring 109, a first positioner 111 is fixedly connected in the sliding ring 109, and a second positioner 210 is fixedly connected in the conical head 203.

[0045] When the drill rod 1 is pressed down, the sliding ring 109 contacts the ground. When the drill rod 1 is pulled out upward, the foot steps on the sliding ring 109 to pull the drill rod 1 upward, thereby effectively preventing excessive soil from adhering to the drill rod 1 and affecting the next fertilization operation.

[0046] At the same time, the positions of the first locator 111 and the second locator 210 are obtained in real time through the controller 105, so that the distance between the fertilization port 3 of the cone head 203 and the ground can be obtained, thereby effectively improving the accuracy of the fertilization depth.

[0047] Example 4: Reference Figure 1-Figure 9 , an improved fertilization device for hilly orchards, is basically the same as Example 1, and further, the two movable plates 401 are both inclined.

[0048] When the sliding movable plate 401 brings with it a plurality of inserting rods 402 and rotates along the axis of the drill rod 1 to break up the soil, Figure 8 and Fig. 9 The cone head 203 rotates clockwise to drive the moving plate 401 to rotate clockwise, and the multiple inclined insertion rods 402 push the broken soil downward so that it can cover the gap at the end of the cone head 203, thereby effectively improving its soil covering effect.

[0049] Example 5: Reference Figure 1-Figure 9 , an improved fertilization device for hilly orchards, is basically the same as Example 1, and further, the lower end of the shunt pipe 208 is provided with an inclined port 209, and the lower end of the shunt pipe 208 is in contact with the sealing plate 301, the sealing plate 301 is symmetrically fixedly connected with a side plate 304, and the lower end of the sealing plate 301 is fixedly connected with a baffle 303.

[0050] The inclined opening 209 has a larger discharge area, which can effectively improve the efficiency of fertilization.

[0051] In the specific fertilization process, further, before the drill rod 1 is pulled upward, the controller 105 first controls the quantitative feeder to supply a specified amount of fertilizer into the shunt pipe 208, and then the outlet end of the shunt pipe 208 is sealed by the sealing plate 301. When the first fertilization is carried out at the deepest part of the soil, the downward moving shunt pipe 208 drives the sealing plate 301 to open. At this time, the outlet end of the shunt pipe 208 and the sealing plate 301 gradually open a certain gap, and the fertilizer flows out, so that a certain amount of fertilizer can be applied to the deep layer in a short time, and the fertilizer can quickly reach the deep soil, and can be accurately and quantitatively fertilized in the deep soil. When fertilizing at other depths, there can be a certain fertilization depth error, so that the fruit trees can be fertilized in all dimensions, which is convenient for the root system to absorb the fertilizer.

[0052] Among them, since most of the root hairs of fruit trees are located deep in the soil, it is necessary to apply a specified amount of fertilizer at a fixed point deep in the soil. Appropriate fertilizer can be applied at other depths, and the root hairs in other areas can also absorb the fertilizer at the same time, thereby effectively improving the fertilization effect on the fruit trees.

[0053] Example 6: Reference Figure 1-Figure 9 , an improved fertilization device for hilly orchards, is basically the same as Example 1, and further, the outer side of the conical head 203 is fixedly connected with multiple groups of fixed rods 4 matching the insertion rods 402, when the movable plate 401 is in the reset state, the insertion rods 402 and the fixed rods 4 form an inclined plate, and the insertion rods 402 and the fixed rods 4 are sealed and slidably connected, and the ends of the fixed rods 4 and the insertion rods 402 are both provided with an inclination angle 404.

[0054] The inclined plate is formed by combining the insert rod 402 and the fixed rod 4. When the drill rod 1 is pressed down, the controller 105 controls the motor 103 to reverse. Fig. 9 At this time, the conical head 203 rotates counterclockwise, and the inclined plate has a certain ability to rotate soil, which makes it easy for the drill rod 1 to be inserted into the soil, and the drill rod 1 is pulled upward so that the inclined plate partially composed of the insertion rod 402 and the fixed rod 4 is convenient for squeezing the scattered soil downward, thereby effectively improving its covering effect, and effectively improving the efficiency and effect of fertilizing fruit trees.

[0055] Embodiment 7: A method for using a device for improving fertilization in a hilly orchard, mainly comprising the following steps:

[0056] Step 1: Hold the hand-held rod 101 and press the drill rod 1 down into the soil at the point where fertilizer is to be applied;

[0057] Step 2: The driving assembly drives the moving plate 401 to slide, the moving plate 401 drives the inserting rod 402 to extend, and the rotating rotating tube 2 drives the inserting rod 402 to rotate along the axis of the drill rod 1;

[0058] Step 3: Pull the hand-held rod 101 upward to move the drill rod 1 upward, and supply fertilizer to the soil at different depths through the fertilization assembly, and loosen the soil to cover the fertilizer.

[0059] 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.
