Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement, in particular to a soil improvement device and a soil improvement method for tea tree planting. Background Art

[0002] Before planting tea trees, improving the soil is a key task that is directly related to the growth of tea trees and the quality of tea.

[0003] Before improving the soil, conduct a comprehensive soil test to analyze indicators such as soil pH, fertility, texture, porosity, and organic matter content. This will help you understand the current status and existing problems of the soil so that targeted improvement measures can be taken. Generally speaking, the pH value of soil suitable for tea growth is between 4.5 and 5.5.

[0004] Soil improvement usually requires the use of a tiller to turn the soil. The tiller mainly controls the rotation of the tiller knife to achieve the effect of turning the soil. When a traditional tiller is in use, the tiller knife acts directly on the compacted ground. Since the compacted layer of the soil is not destroyed, the contact area between the tiller blade and the soil is large, and the blade is also subjected to a large reaction force from the soil. If the tiller knife acts too deep into the soil, it may cause the blade to break. This requires the tiller knife to crush the soil in multiple times to reach the depth required for tea tree planting, which undoubtedly reduces the efficiency of soil improvement. Summary of the Invention

[0016] As a further solution of the present invention: the acid liquid pumping mechanism includes a piston cylinder fixedly mounted on the workbench, a second rotating rod rotatably mounted in the piston cylinder, and a second belt connected to the first transmission rod is sleeved on the second rotating rod;

[0017] The piston cylinder is provided with multiple one-way valves, which are respectively connected to the discharge pipe and the feed pipe. Under the action of the one-way valves, the solution in the pumping box can only enter the piston cylinder through the feed pipe and be discharged through the discharge pipe.

[0018] As a further embodiment of the present invention, the acid liquid pumping mechanism further comprises an annular groove formed on the second rotating rod, a movable sleeve being slidably mounted on the second rotating rod, a limit block being fixed to the inner wall of the movable sleeve and slidably engaged with the annular groove, a piston disk being fixed to the movable sleeve and slidably connected to the piston cylinder, and a conveying assembly being provided on the piston cylinder;

[0019] The annular groove is composed of two symmetrical groove bodies arranged in a spiral shape, and the number of spiral turns of a single spiral groove is half a turn.

[0020] As a further solution of the present invention: the conveying assembly includes a feed pipe and a discharge pipe connected to the piston cylinder and symmetrically arranged, a nozzle is fixed on the movable rod, the feed pipe is connected to the pumping box, and the discharge pipe is connected to the nozzle.

[0023] A soil improvement method for tea tree planting comprises the following steps:

[0024] Step 1: Place the device on the soil to be treated;

[0025] Step 2: Under the action of the soil turning mechanism, the soil turning cone rod is controlled to be inserted into the soil to a certain depth and pulled out at a specific angle to perform the soil turning action;

[0026] Step 3: The soil turning mechanism also drives the acid pumping mechanism to move, so that the solution in the pumping box is sprayed onto the turned soil;

[0027] Step 4: Under the action of the stirring component, ensure that the solution in the pumping box remains mixed. At the same time, the stirring component controls the rotation of the tiller through the stirring mixing component to perform a mixing action on the soil and solution.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the present application can achieve the effect of first reducing the compaction of the soil, making the compacted soil softer, and then crushing the loose soil through the mutual cooperation between the soil-turning cone rod and the soil-turning knife; specifically, when the soil-turning mechanism is working, the soil-turning cone rod can be controlled to be inserted into the soil, and the soil can be excavated to break the compacted layer on the upper part of the soil and preliminarily loosen the soil layer; at the same time, the soil-turning mechanism will also drive the acid pumping mechanism to work, so as to pump the solution in the pumping box to the surface of the turned soil. Under the action of the stirring component, it can be ensured that the pumped solution always remains in a mixed state. At the same time, the stirring component will also drive the stirring and mixing component to move, so as to crush the turned soil through the soil-turning knife.

[0029] The soil is turned over in advance by the tiller, which greatly reduces the compaction of the soil. The tiller then crushes the soil, which not only increases the crushing effect of the soil, but also achieves the purpose of soil improvement in a single operation. Since the soil refinement and crushing is divided into two steps, the intensity of a single operation is significantly reduced. Moreover, before the tiller crushes the soil, the solution is sprayed on the surface of the turned soil. During the soil crushing process of the tiller, the soil and the solution are fully mixed, so that the solution and the soil are fully contacted and mixed, thereby ensuring that the soil is fully improved.

[0030] The continuous stirring of the stirring blades ensures that the solution is always kept in a mixed state to avoid stratification when the prepared solution is placed in the pumping box for a long time. This will lead to different concentrations of the solution sprayed on the soil, and some areas may become over-acidic, over-alkaline, over-fertilized or under-fertilized, thereby ensuring the best soil improvement effect.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0043] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0044] See also Figures 1 to 10 In an embodiment of the present invention, a soil improvement device includes:

[0045] A workbench 1, and a set of support plates 2 and a set of fixing plates 4 fixedly disposed on the workbench 1, wherein each set of the support plates 2 and fixing plates 4 has two plates and is symmetrically disposed on the workbench 1. A pumping box 12 is also fixed on the workbench 1;

[0046] Also includes:

[0047] A soil turning mechanism is provided on the fixed plate 4, and the soil turning mechanism includes a soil turning cone rod 11, and the soil turning mechanism can drive the soil turning cone rod 11 to perform a reciprocating excavation action;

[0048] an acid liquid pumping mechanism, disposed on the workbench 1 and connected to the soil turning mechanism, the acid liquid pumping mechanism being capable of pumping the solution in the pumping box 12 when the soil turning mechanism moves;

[0049] The stirring assembly is arranged on the pumping box 12, and the support plate 2 is provided with a stirring and mixing assembly connected to the stirring assembly. The stirring and mixing assembly includes a soil-turning knife 18, and the stirring assembly can drive the soil-turning knife 18 to rotate through the stirring and mixing assembly.

[0050] Specifically, since tea trees require a deeper planting depth, when improving the soil, the device can be placed on the soil that needs to be improved. At the same time, under the action of the soil-turning mechanism, the soil-turning cone rod 11 is controlled to perform irregular reciprocating motions in the vertical and horizontal directions to turn the soil, thereby breaking the compacted layer of the soil, increasing the porosity of the soil, and improving the air permeability and water permeability of the soil. The soil-turning mechanism will also drive the acid pumping mechanism to move to transport the liquid in the pumping box 12 to the turned soil, and under the action of the stirring component, the solution in the pumping box 12 can be continuously stirred to prevent the solution from being stratified due to standing for a long time, ensuring that the solution is always in a mixed state, and the stirring component will also drive the stirring The mixing assembly moves to control the rotation of the tilling knife 18. Under the action of the tilling knife 18, the turned over soil is further crushed, and the solution sprayed on the soil is mixed with the crushed soil and then refilled into the turned over soil pit to adjust the pH of the soil to the soil acidity required by the tea tree. When the tilling knife 18 crushes the soil, the tilling cone rod 11 has broken the compacted layer of the soil and the soil is in an turned over state. Therefore, when the tilling knife 18 refines and crushes the soil, the blade of the tilling knife 18 is subjected to a smaller reaction force from the soil, which not only protects the tilling knife 18, but also increases the depth to which the tilling knife 18 can crush the soil, thereby achieving the effect of efficiently improving the soil.

[0051] See also Figure 1-Figure 7 The turning mechanism includes a first motor 5 fixedly mounted on the fixed plate 4, a first transmission rod 6 connected to the output shaft of the first motor 5 is rotatably mounted on the fixed plate 4, a rotating plate 7 is fixed on the first transmission rod 6, and a driven assembly is provided on the rotating plate 7, the driven assembly includes a support column 8 fixedly mounted on the rotating plate 7, a movable rod 9 is rotatably mounted on the support column 8, a movable plate 10 is fixed to the end of the movable rod 9, and the movable plate 10 is fixed to the turning cone rod 11, and the driven assembly also includes a hinged rod 13 hinged on the pumping box 12 and hinged to the movable rod 9.

[0052] In detail, the device can be moved to the soil to be processed. Before turning the soil, the support column 8 is at the end of its stroke away from the workbench 1. Under the action of the movable rod 9 and the movable plate 10, the turning cone rod 11 is located outside the soil. At this time, the hinged rod 13 is lifted to the maximum height. Under the action of the hinged rod 13, the angle between the movable rod 9 and the fixed plate 4 is adjusted to the maximum angle, so that the end of the turning cone rod 11 away from the movable plate 10 is in a tilted state.

[0053] When the soil needs to be improved, the first motor 5 works and drives the first transmission rod 6 to rotate, thereby controlling the support column 8 to move around the first transmission rod 6 through the rotating plate 7, thereby controlling the movable plate 10 to move toward the soil through the movable rod 9. At the same time, when the movable rod 9 follows the support column 8 to move along the arc trajectory, the lifting height of the hinged rod 13 is reduced. Under the action of the pulling force of the hinged rod 13, the movable rod 9 is deflected toward the hinge point of the hinged rod 13, so that the angle between the movable rod 9 and the fixed plate 4 is gradually reduced, and the soil turning cone rod 11 will gradually insert into the soil, and the angle between it and the horizontal plane gradually tends to be vertical. When the first transmission rod 6 rotates half a circle, the support column 8 is moved around the first transmission rod 6, thereby controlling the movable plate 10 to move toward the soil. The distance between the column 8 and the workbench 1 is the smallest, so that the soil-turning cone rod 11 is inserted into the soil to the maximum depth. At this time, the first transmission rod 6 continues to rotate to move the movable rod 9 toward the initial height, and the articulated rod 13 will be lifted. Under the thrust generated by the lifting of the articulated rod 13, the movable rod 9 will swing in the direction away from the fixed plate 4, and the soil-turning cone rod 11 will generate an excavation force on the soil, thereby turning over the soil. When the first transmission rod 6 rotates one circle, the soil-turning cone rod 11 detaches from the soil and returns to its initial position. At this time, under the action of the wheel 3, the device can be controlled to move along the length direction of the soil to be processed to the next soil-turning position, and the above steps are repeated to perform the soil-turning action.

[0054] Preferably, before planting tea trees, the required deep plowing depth is generally 40-60 cm, and the end of the soil-turning cone rod 11 is set in a conical shape. When it comes into contact with the soil, it can be inserted into the soil more easily, and the insertion depth is also deeper, thereby meeting the depth required for planting. When the soil-turning cone rod 11 is inserted to the maximum depth, and in the process of separating from the soil and tilting up, by applying multi-point force to the soil, it can simulate the effect of manually digging the soil by humans, and there is adhesion between the soils. In the area where the soil-turning cone rod 11 acts, the soil can be turned over, thereby breaking the compacted layer of the soil, increasing the porosity of the soil, improving the air permeability and water permeability of the soil, and promoting the growth of the tea tree root system. After the soil is loosened, it can also ensure that the subsequent soil-turning knife 18 can smoothly refine and crush the soil.

[0055] See also Figure 1 、 Figure 2 、 Figure 4 、 Figures 8-10 The acid liquid pumping mechanism includes a piston cylinder 19 fixedly mounted on the workbench 1, a second rotating rod 20 is rotatably mounted in the piston cylinder 19, and a second belt 21 connected to the first transmission rod 6 is sleeved on the second rotating rod 20. The acid liquid pumping mechanism also includes an annular groove 2001 opened on the second rotating rod 20, and a movable sleeve 22 is slidably mounted on the second rotating rod 20. A limit block 23 that slides and engages with the annular groove 2001 is fixed on the inner wall of the movable sleeve 22, and a piston disk 24 that is slidably connected to the piston cylinder 19 is fixed on the movable sleeve 22. A conveying assembly is provided on the piston cylinder 19, wherein the conveying assembly includes a feed pipe 25 and a discharge pipe 26 that are connected to the piston cylinder 19 and are symmetrically arranged, and a nozzle 27 is fixed on the movable rod 9, the feed pipe 25 is connected to the pumping box 12, and the discharge pipe 26 is connected to the nozzle 27.

[0056] It should be noted that a plurality of one-way valves are provided on the piston cylinder 19, which are respectively connected to the discharge pipe 26 and the feed pipe 25. Under the action of the one-way valves, the solution in the pumping box 12 can only enter the piston cylinder 19 through the feed pipe 25 and be discharged through the discharge pipe 26. The annular groove 2001 is composed of two symmetrical and spirally arranged groove bodies. The number of spiral turns of a single spiral groove is half a turn. In the initial state, the limit block 23 is located at the end of the stroke on one side of the annular groove 2001, so that the piston disc 24 and the movable sleeve 22 are located at the end of the stroke on one side of the piston cylinder 19. At this time, under the action of the piston disc 24, the piston cylinder 19 is divided into two cavities, and the larger cavity is filled with solution.

[0057] When the first transmission rod 6 rotates, the soil turning cone rod 11 is controlled to be reciprocated and inserted into the soil for soil turning processing. At the same time, the first transmission rod 6 will drive the second rotating rod 20 to rotate through the second belt 21, thereby driving the annular groove 2001 to move. Under the action of the annular groove 2001, the limit block 23 will slide along the trajectory of the annular groove 2001, thereby driving the movable sleeve 22 to move, and the movable sleeve 22 will drive the piston disc 24 to move. Since the piston disc 24 is slidably connected to the piston cylinder 19, the piston disc 24 can only slide along the length direction of the second rotating rod 20 and will not rotate with the second rotating rod 20. Under the action of the piston disc 24, the internal pressure of the cavity filled with solution increases. Under the action of pressure, the solution is pushed into the nozzle 27 through the discharge pipe 26. The solution will be evenly sprayed on the turned soil through the nozzle 27. At the same time, under the action of the piston disc 24, the pressure in the smaller cavity is reduced. Under the action of negative pressure When the second rotating rod 20 rotates one circle, the piston disc 24 is reset, and the above steps are repeated, thereby realizing continuous spraying of the solution when the soil is turned over, so as to achieve the effect of improving the soil conditions.

[0058] Preferably, when planting tea trees, the soil is first comprehensively tested to analyze the soil's pH, fertility, texture, porosity, organic matter content and other indicators to understand the soil's current status and existing problems so that targeted improvement measures can be taken. Generally speaking, the soil pH value suitable for tea tree growth is between 4.5 and 5.5. Therefore, if the soil pH deviates from the required planting adjustment, an acidic or alkaline solution can be prepared according to the deviation value, and the solution can be sprayed onto the turned soil by spraying the nozzle 27. Similarly, if fertilization or other treatments are needed, the corresponding solution can be prepared accordingly, and the soil can be improved by spraying. Therefore, the solution in the pumping box 12 can be added to the corresponding solution according to the soil improvement requirements to improve the soil to the planting conditions required for tea trees.

[0059] See also Figure 8The stirring assembly includes a second motor 14 fixedly mounted on the side wall of the pumping box 12, and a second transmission rod 15 connected to the output shaft of the second motor 14 is rotatably mounted in the pumping box 12, and a plurality of stirring blades 28 equidistantly distributed around the circumference are fixed on the second transmission rod 15.

[0060] Furthermore, when the second motor 14 is working, it drives the second transmission rod 15 to rotate, thereby driving the stirring blade 28 to move. Under the action of the stirring blade 28, the solution in the pumping box 12 is stirred and mixed. Among them, if the prepared solution is placed in the pumping box 12 for a long time, the solution may be stratified, which will cause the concentration of the solution absorbed by the feed pipe 25 to be inconsistent, and the corresponding concentration of the solution sprayed onto the soil is different. When the soil is improved, some areas may become over-acidic, over-alkaline, over-fertilized or under-fertilized. Therefore, when spraying the solution, the continuous stirring of the stirring blade 28 can ensure that the solution is always kept in a mixed state to ensure the best soil improvement effect.

[0061] See also Figure 1-Figure 4 The stirring and mixing assembly includes a first rotating rod 17 rotatably mounted on the support plate 2, the first rotating rod 17 is fixedly connected to the tilling knife 18, the first rotating rod 17 is sleeved with a first belt 16 connected to the second transmission rod 15, and a circular arc baffle 29 sleeved on the tilling knife 18 is fixed to the bottom of the workbench 1, and a protective plate 201 sleeved on the first belt 16 is fixed to the side wall of the support plate 2.

[0062] Furthermore, when the second transmission rod 15 rotates, it will also drive the first rotating rod 17 to rotate through the first belt 16, thereby driving the turning knife 18 to rotate. Since the turning knife 18 extends into the soil, under the action of the turning knife 18, the soil turned over by the turning cone rod 11 is further refined and crushed. The arc baffle 29 can block the soil crushed by the turning knife 18, which can prevent the soil from splashing and guide the crushed soil back to the turned soil pit. The protective plate 201 can protect the rotating shafts of the first belt 16 and the first rotating rod 17, thereby preventing the soil from sticking to the rotating shafts of the first belt 16 and the first rotating rod 17, ensuring that the transmission will not be affected.

[0063] Among them, when the traditional tiller 18 is in use, since the tiller 18 directly acts on the compacted ground, the contact area between the blade of the tiller 18 and the soil is large, and the blade is also subjected to a large force from the soil. If the tiller 18 acts too deeply on the soil, it may cause the blade to break. This requires the tiller 18 to crush the soil in multiple times to reach the required depth, which undoubtedly reduces the efficiency of soil improvement. The present device first turns the soil in advance through the tiller cone rod 11, which greatly reduces the compaction of the soil, and then crushes the soil through the tiller 18, which can not only increase the crushing effect of the soil, but also achieve the purpose of completing soil improvement in a single operation.

[0064] Preferably, during the process of acidifying or alkalizing the soil, if the acid (alkali) solution is not mixed with the soil, the acid (alkali) may be locally concentrated, resulting in excessive decrease (increase) in the soil acidity (alkalinity) in some areas, while the pH value in other areas hardly changes, and the purpose of adjusting the soil pH value to a range suitable for tea tree growth cannot be achieved. Before the soil is broken by the tiller 18, the solution is sprayed on the surface of the turned soil. During the soil breaking process of the soil by the tiller 18, the soil and the solution can be fully mixed, so that the solution and the soil are fully contacted and mixed, thereby ensuring the best effect of soil improvement.

[0065] A method for improving soil for tea tree planting comprises the following steps:

[0066] Step 1: Place the device on the soil to be treated;

[0067] Step 2: Under the action of the soil turning mechanism, the soil turning cone rod 11 is controlled to be inserted into the soil to a certain depth and pulled out at a specific angle to perform the soil turning action;

[0068] Step 3: The soil turning mechanism also drives the acid pumping mechanism to move, so that the solution in the pumping box 12 is sprayed onto the turned soil;

[0069] Step 4: Under the action of the stirring component, ensure that the solution in the pumping box 12 remains mixed. At the same time, the stirring component controls the rotation of the tilling blade 18 through the stirring and mixing component to perform a mixing action on the soil and the solution.
