At the same time, the rotation force of the motor rotates the outer pipe through the two bevel gears. The outer pipe is vertically lowered while rotating so as to dig into the ground. In this state, compressed air and a liquid chemical pass through the inner pipe and are simultaneously jetted in the radial direction in a 360-degree full range through the plurality of openings (146) provided at the lower end of the penetrating and breaking rod. Therefore, a subsoil plow pan is finely broken and the liquid chemical is supplied to the broken soil.

Description

Subsoil crusher which can supply soil improver and liquid fertilizer to subsoil and subsoil crushing at the same time

The present invention relates to a soil crusher, and more particularly, to a soil crusher capable of simultaneously performing soil reformer and / or liquid fertilizer (liquid ratio) in addition to subsoil crushing.

Arable land is generally compacted due to the frequent operation of agricultural machinery, resulting in a hard layer that hardens between about 20 to 40 cm in soil depth. Increasing use of large-scale agricultural machinery and livestock feeding of rice straw have led to an increasingly severe stratification. The hard layer has very low soil porosity and poor breathability and drainage. Bad soil drainage can cause crops to moisten and cause significant declines in root vitality, resulting in lower productivity.

Subsoil crushing is known as a good way to solve this problem. According to the Agriculture Promotion Agency, about 440,000 ha, about half of the rice fields in Korea, need to be subdivided. In addition, in order to cultivate field crops such as soybeans well in these paddy fields, once every 3 years (quality soil) and 5 years (sand soil), the soil is broken down to about 35cm depth before farming to prevent wetness and yield of soybeans. It is known that it can increase to about 40%.

As the subsoil crushing work to crush the light layer is recognized as an almost essential work in farming, subsoil crushing technology for this has been proposed in various ways. One of them is the 'soil crusher' presented by Kwon Tae-Woon Korean Patent Publication No. 10-2012-0119287 (published October 31, 2012). This subsoil crusher shown in FIG. 1 is provided with a compression main body 10, an over valve 40, a flow control valve 45, an air supply line 50, a crushing member 60, and safety prevention means 70. It has a configuration. Air is introduced into and stored in the compression body 10 through the air supply line 50 connected to the compressor and by adjusting the over valve 40, and when the soil is crushed, the flow control valve 45 is adjusted to control the compression body 10. Compressed air is discharged into the inner layer while controlling the amount of compressed air stored in The crushing member 60 is combined with the flow control valve 45 to be inserted into the light layer for subsoil crushing so as to supply compressed air to the soil so that the soil is crushed. This subsoil crusher is characterized by crushing the soil using compressed air.

Other conventional soil crushing apparatuses are known as soil shredding, as follows: Korean Patent Registration No. 10-1161535 (registered on June 25, 2012, Applicant Green Solutions Co., Ltd. Soil Crushing Purification System) and Korean Patent Publication No. 10-2009-0104464 (October 06, 2009, published by Cornell D. Flebani et al., Title of the Invention: Compressive Crushing and Multicomponent Liquid or Solid Media) Method and apparatus for improving the purification efficiency of underground soil and groundwater pollution using

These conventional subsoil crushers all have in common that they crush soil using compressed air. However, the shredder devices have a limitation in that they have only soil shredding functions. The shredder devices do not have the ability to perform other tasks besides soil shredding, such as fertilizing the soil or adding soil modifiers to improve the soil. Therefore, a cultivator using the subsoil crusher must separate the work by preparing a separate equipment to administer the liquid fertilizer and / or soil modifier to the soil separately from the subsoil crushing work using the subsoil crusher. Soil modifiers are various materials used in soil to improve physically, chemically, and biologically unhealthy soils, and are organic synthetic polymer compounds applied to soils for the purpose of improving physical properties by agglomerating or granulating soil. Soil modifiers are available commercially in liquid and solid (powder) forms.

In addition, the existing manual submersible soil crusher that is dragged or pushed by the worker is a structure in which the crushing rod penetrates into the ground by the force pressed by the worker. To put the crushing rod deep into the ground, the worker must use a lot of power. In addition, there is a limit to the depth that can penetrate the crushing rod into the ground only by the force of the operator.

In view of the limitations of the prior arts described above, by supplying compressed air with liquid fertilizer and / or soil modifier from the infiltration crushing rod digging into the ground, it is possible to supply fertilizer and / or soil modifier to the crushed soil together with the crushing of subsoil.

In addition, it maximizes the efficiency of the fertilizer or soil improver in the soil. In addition, since one or two air compressors can simultaneously perform two or three operations, it also has the effect of reducing the cost of equipment for farmers.

The subsoil crusher of the present invention uses the rotational force by the drill of the end of the penetrating crushing rod driven by the motor and the pressing force to the hydraulic or pneumatic cylinder. Since the penetrating crushing rod is pressed while rotating, the penetrating crushing rod can be penetrated more deeply than the conventional crusher. In addition, such penetrating force is generated by using a motor and a hydraulic or pneumatic cylinder, so that the operator does not have to apply a large force. Penetration depth can be appropriately adjusted to the desired level. It can penetrate and crush to a depth of 40 cm or more, preferably 70 to 80 cm. This ability to penetrate the subsoil also allows cross-cutting to be performed even where irrigation is not possible.

In addition, the subsoil crusher can be compactly manufactured and has good mobility using wheels. Subsoil crushing can be performed even when crops are in the arable land, so that the arable land can be deeply grounded. The furrows of arable land tend to become hard due to the frequent passage of people or agricultural machinery.

Support it. In the figure, the four sides 114 only indicate their boundaries with dashed lines so as not to interfere with the representation of the other components. Two wheels 117 are attached to the lower side of the housing 100, and a handle 118 is attached to the upper side of the housing 100. The height of the housing 100 preferably has a height of about a waist to a chest of the user. The user may work while moving the subsoil crusher 100 on the work target land by using the handle 118 and the wheel 117. Of the above-mentioned subsoil crusher 100, only the control means 190 is installed outside the housing 110, and the rest is installed inside the housing 110.

The vertical raising and lowering means 160 is a means for converting the energy of hydraulic pressure or compressed air pressure into mechanical reciprocating linear motion. For example, it may be implemented as a hydraulic cylinder or a pneumatic cylinder. Hereinafter, a case in which the hydraulic cylinder 160 is adopted for convenience will be described. Those skilled in the art will have no difficulty in constructing a system employing a pneumatic cylinder based on the description using the hydraulic cylinder 160 as an example.

The hydraulic cylinder 160 is fixed in such a way as to hang upside down on the housing upper surface 112. That is, the base of the cylinder body 162 is fixed to the upper surface 112 of the housing 110, and the upper portion of the cylinder body 162 is disposed to face the lower surface 113 of the housing 110. The piston rod 164 is connected to a piston (not shown) in the cylinder body 162, and a portion of the piston rod 164 is exposed outside the cylinder body 162 so that the piston rod 164 of the housing 110 can be parallel to the support guide rods 115. To face the lower surface (113). At the base and the top of the cylinder body 162 are

fluid passages

166 and 168 through which fluid can enter and exit from the outside.

The hydraulic control means 170 includes a fluid supply line connecting the external hydraulic supply device 240 and the cylinder body 162 to form a closed hydraulic circuit. The external hydraulic supply device 240 may be embodied as, for example, a two-way hydraulic pump, but this is exemplary and may be used as long as it is a known power source of the hydraulic cylinder.

The fluid supply line includes first and second fluid input pipes 172-1 and 172-2 connected to two inlets and outlets of the hydraulic supply device 240, and a first fluid input pipe 172-1. The first fluid passage 176 connected to the first fluid passage 166 and the second fluid passage 177 connected to the second fluid passage 168 in the second fluid input tube 172-2 are included. The fluid supply line also includes at least one electrically controlled valve for controlling the opening and closing of the line. In the figure, in order to ensure reliable opening and closing control of the fluid passage (176, 177), the electrically controlled valve 174 and the valve 175 are respectively installed in the first fluid passage 176 and the second fluid passage (177). Illustrated. Examples of electrically controlled

valves

174 and 175 include solenoid valves.

According to the size of the hydraulic pressure of the upper and lower parts of the piston (not shown), the piston makes a linear motion, and the piston rod 164 connected to the piston also moves up and down in the vertical direction by the piston stroke. That is, the length of the piston rod 164 protruding out of the cylinder body 162 is varied by the piston stroke.

Each of the compressed air tank 120 and the chemical container 130, which are containers for compressed air and a chemical liquid (liquid fertilizer and / or a soil modifier, etc., refers to a liquid), is installed at an upper portion of the housing 110. The two are combined to move like a body by the coupling member 186. The coupling member 186 is made of a metal plate, and is coupled to the body of the compressed air tank 120 and the chemical liquid container 130 by welding. For the welding coupling, the compressed air tank 120 and the chemical liquid container 130 is preferably made of a metal material. In addition, the coupling member 186 is extrapolated to the four support guide rods 115 through the guide bushing 183b, and can slide along the support guide rod 115 in the vertical direction.

The force transmission means 180 connects the compressed air tank 120 and the chemical liquid container 130 with the piston rod 164 to vertically raise and lower the body. The force transmission means 180 includes a force transmission member 182 in the form of a plate, for example, connecting them in a horizontal direction. This force transmission member 182 is extrapolated to the piston rod 164. At the same time, the force transmission member 182 is integrally connected with the compressed air tank 120 and the chemical liquid container 130 by welding, for example, and serves as a coupling member of the two

containers

120 and 130. Like the coupling member 186, the force transmission member 182 is coupled to the four support guides 115 so as to slide in the vertical direction via the guide bushing 183a. Compressed air tank 120 and the chemical liquid container 130 is coupled to the lower portion and the upper portion by the force transmission member 182 and the coupling member 186 in a more rigid body.

In addition, the force transmission means 180 is the first and second force transmission ring (184, 185) fitted at two points of the piston rod 164, that is, just above and below the portion where the force transmission member 182 is fitted. It includes. The first and second force transmission rings 184 and 185 firmly engage with the piston rod 164 so that there is no slip in the vertical direction. The force that the piston rod 164 descends vertically is the first force transmission ring 184 directly above the force transmission member 182, and the force that rises vertically is the second force transmission just below the force transmission member 182. Ring 185 transmits to force transmission member 182.

By such a configuration, the force transmission means 180 transfers the vertical raising and lowering movement of the piston rod 164 to the compressed air tank 120 and the chemical liquid container 130 as it is. Therefore, when the piston rod 164 moves up and down vertically, the compressed air tank 120 and the penetration crushing rod 140 and the chemical liquid container 130 which are integrally connected thereto become one body with the piston rod 164 and are the same. Forced to do a vertical lift.

4 illustrates a coupling relationship between the structure of the penetrating crushing rod 140 and the peripheral components. Penetration crushing rod 140 has a double tube structure consisting of an inner tube 142 and an outer tube 144 containing the inner tube 142. Penetration crushing rod 140 is preferably made of a high strength metal material.

The inner tube 142 is coupled in communication with the compressed air tank 120 and the chemical liquid container 130, respectively, and serves as a jet passage for the compressed air and the chemical liquid. The inner tube 142 is integrally coupled to the inlet of the upper end of the compressed air tank 120 by, for example, welding or screwing. By such a direct coupling, the inner tube 142 is integrated with the compressed air tank 120 and the vertical lifting motion by the vertical lifting force of the vertical lifting means 160 which the compressed air tank 120 transmits. can do. The inner tube 142 also extends vertically downward in parallel with the support guide rods 115 so that its distal end projects out of the lower surface of the housing 113.

An electrically controlled valve 122 such as a solenoid valve is installed at the upper end of the inner tube 142, that is, near the lower outlet of the compressed air tank 120. This valve 122 is for controlling the compressed air in the compressed air tank 120 is ejected to the inner tube (142). An electrically controlled valve 124 is installed near the upper inlet of the compressed air tank 120. The valve 124 is for controlling the inlet of the compressed air in the compressed air storage tank 210 into the compressed air tank 120.

The inner tube 142 is also in communication with the lower portion of the chemical liquid reservoir 130 through the chemical liquid tube 132. An electrically controlled valve 134 may also be installed at the lower outlet portion or the chemical liquid tube 132 of the chemical liquid container 130. This valve 134 is for controlling the chemical liquid in the chemical liquid container 130 is introduced into the inner tube 142. The chemical liquid tube 132 is preferably connected to the inner tube 142 at a lower point than the valve 122. An electrically controlled valve (not shown) may be further installed at the upper inlet of the chemical liquid container 130 connected to the chemical liquid storage tank 220.

Facade 144 is configured to dig into the ground while rotating. To this end, the exterior 144 includes a non-rotatable inner tube 142 and is rotatably installed therein. Appearance 144 extends downward, including the inner tube 142 from a lower point than the connection point of the valve 122 and the chemical liquid tube 132, the drill 148 is mounted at the end thereof.

The top of the exterior 144 is provided with exterior rotating means 150 for rotating the exterior 144. Appearance rotating means 150 is a motor support member that is integrally connected to the force transmission member 182 while supporting the motor 152, two

bevel gears

153, 154, and the motor 152 that is electrically driven ( 156).

The appearance 144 rotates by the rotational force of the motor 152. The first bevel gear 154 is coupled to the rotation shaft of the motor 152. The second bevel gear 153 is integrally coupled to the upper end of the exterior 144 using, for example, a bolt. The first bevel gear 154 and the second bevel gear 153 mesh with each other. The rotational force of the motor 152 is transmitted to the exterior 144 through two

bevel gears

153 and 154.

The motor 152 is fixed to and supported by the motor support member 156. The motor support member 156 is coupled to the force transmission member 182 is to move vertically integrally with it. Therefore, the external rotation means 150 also makes a vertical lifting movement in synchronization with the piston rod 164 when the vertical lifting movement. While the piston rod 164 is vertically lowered, the motor 152 and the first bevel gear 154 are also vertically lowered, at which time the first bevel gear 154 is externally 144 through the second bevel gear 153. ) Down vertically. As a result, while the vertical lowering of the piston rod 164 and the rotation of the motor 152 occur at the same time, the appearance 144 rotates while making the vertical lowering movement. Penetration crushing rod 140 is to dig the ground while doing this movement.

In contrast, there is further provided a means for transferring the force generated during the vertical rise of the piston rod 164 vertically lowered to the lowest point of the stroke to the exterior 144 to vertically raise the exterior 144. This means comprises a gear support member 188, a guide bushing 183 and a bearing 189.

The gear support member 188 is slidably extrapolated to the four support guide rods 115 via the guide bushing 183c, and is preferably made of a high strength metal sheet. The gear support member 188 is also extrapolated to the exterior 144. A ring bearing 189 is disposed directly below the second bevel gear 153 to rotatably support the second bevel gear 153. This bearing 189 is fixed to the gear support member 188. The gear support member 188 is integrally connected to the motor support member 156. Therefore, the gear support member 188 is integrated with the motor support member 156 and the force transmission member 182, through which the vertical lifting movement such as the piston rod 164.

While the piston rod 164 performs the vertical upward movement, the gear support member 188 also moves in the same way. Accordingly, the bearing 189 pushes the second bevel gear 153 vertically upward, so that the exterior 144 may be raised by the distance that the piston rod 164 is raised. It is preferable to further add a member directly connecting the gear support member 188 and the force transmission member 182 to the opposite side of the motor support member 156 to more firmly connect the two members. Of course, the gear support member 188 only needs to be able to receive the vertical lifting force of the piston rod 164, and thus, for example, the piston rod in addition to the motor support member 156 or other members other than the motor support member 156. 164, the compressed air tank 120, the chemical liquid container 130, and may be coupled to at least one of the force transmission member 182.

Corresponding points of the distal ends of the inner tube 142 and the outer tube 144 are provided with a plurality of openings 146 through which compressed air and chemical liquid can be ejected 360 degrees in all directions. Drill 148 is located just below these openings 146. For example, it is preferable that at least four openings 146 are provided toward the north, south, east, west, and south so that compressed air and the chemical liquid are ejected into the soil in the radial direction of the north, south, east, west, and north through the openings.

The control means 190 controls the driving of the vertical raising and lowering means 160, the driving control of the motor 152 for the external rotating means 150, the supply and discharge control of the compressed air to and from the compressed air tank 120, Means for performing supply and release control of the chemical liquid to / from the chemical liquid container 130, and the like. The control means 190 includes a control box 192 fixed to the side wall of the housing 110, a control circuit (not shown) embedded therein, and a plurality of control switches 194 capable of giving a user command to the control circuit. It includes.

The provided control switch 194 is an air injection switch S1 for instructing compressed air injection into the compressed air tank 120, a chemical liquid supply switch S2 for instructing a chemical liquid supply into the chemical container 130, and a crushing infiltration. Penetration switch (S3) for instructing the rod 140 is to vertically descend into the soil, the compressed air and the chemical liquid through the opening of the penetration crushing rod 140 penetrating into the soil to crush the soil There is a crush switch (S4) for indicating, and a retraction switch (S5) for instructing to retreat, ie, vertically retracts the infiltration crushing rod 140 to its original position (retracted position) after soil crushing.

The control circuit receives a signal according to a user's operation from each control switch and controls the relevant components so that an operation corresponding to the input signal can be made. To this end, the control circuit includes hardware such as an operation control unit (CPU), a memory, control switches 194 and a wiring circuit that electrically connects the control object with the operation control unit. In addition, a program control program is also provided to the tasks to be performed for each input signal provided from the control switch 194 and stored in a memory. The arithmetic and control device controls the control targets with a control signal generated by executing the control program. Specific control content of the control means 190 will be described together in the process of describing the overall operation of the subsoil crusher system 200 described below.

(1) 준비 단계(1) preparation step

This step is a step in which the user moves the subsoil crusher 100 to a desired point or moves, and then prepares for subsoil crushing.

At this stage, the piston rod 164 is retracted to the top as shown in FIG. 3 (this is the state in which the piston in the cylinder body 162 is at the bottom dead center), and thus the crushing rod 140 is in the retracted position. Is in. For the preparatory work, the user presses the air injection switch S1. When a switching signal is generated in the air injection switch S1, the control circuit controls the compressed air to be filled in the compressed air tank 120, and the chemical liquid container 130 is filled with at least one injection amount of the chemical liquid. That is, the upper valve 124 and the lower valve 122 of the compressed air tank 120 is in a closed state, and when the air injection switch S1 is operated, the upper valve 124 is opened to open the external compressed air storage tank. Part of the compressed air stored in the 210 is introduced into the compressed air tank 120 and stored.

Since the chemical storage tank 220 maintains a pressurized state by the compressor 230, the chemical liquid reservoir 130 always maintains a full state of the chemical liquid. However, in order to more reliably control the chemical liquid supply to the chemical liquid container 130, an electronically controlled valve (not shown) may be further installed in the chemical liquid pipe 233. In this case, the chemical liquid supply to the chemical liquid container 130 may be controlled by operating the chemical liquid operation switch S2.

(2) 침투 단계(2) infiltration stage

This step is performed after the preparation work is completed. This step is to drive the crushing rod 140 to the desired depth in the ground. To this end, the user stands the housing 110 vertically with respect to the ground, and then manipulates the penetration switch S3. The control circuit of the control means 190 receives the signal of the infiltration switch (S3) and performs the following control.

First, in order to push the piston rod 164 long out of the cylinder body 162 by moving the piston at the bottom dead center in the cylinder body 162 to the top dead center, the control circuit functions as (i) the hydraulic supply device 240. The start of the operation of the bidirectional pump rotates in the first direction, and (ii) instructs the opening of all the

valves

174 and 175 in the hydraulic circuits 172-1, 176, 162, 177 and 172-2. As a result, the fluid in the hydraulic circuit is pressurized by the hydraulic supply device 240, and the cylinder body (via the first fluid passage 166 via the first fluid input tube 172-1 and the first fluid passage 176). 162) Push in and push the piston up to top dead center. The fluid at the top dead center side of the piston is pushed out of the cylinder body 162 through the second fluid passage 168, so that the hydraulic pressure supply device passes through the second fluid passage 177 and the second fluid input tube 172-1. (240).

When the piston moves from the bottom dead center to the top dead center by the hydraulic force, the piston rod 164 extends vertically downward by the distance (stroke) the piston has moved, and thus is directly or indirectly moved to move integrally with the piston rod 164. Other components that are coupled in combination are also forced to move vertically downwards by the stroke of the piston. That is, the compression air tank 120 and the chemical liquid container 130 integrally connected to the piston rod 164 through the force transmission member 182, and the penetration crushing rod 140 directly connected to the compressed air tank 120 The inner tube 142 also moves vertically downward by the stroke distance of the piston rod 164. At this time, since the coupling member 186, the motor support member 156, the gear support member 188 and the components fixed thereto are also directly and indirectly connected to the force transmission member 182, the piston rod It is moved vertically downward by the stroke of 164. As a result, the inner tube 142 of the penetration crushing rod 140 is penetrated into the ground by the stroke of the piston by the force of the compressed air tank 120.

However, only by pressing the penetrating crushing rod 140 vertically, it is not easy to dig deep into the transverse layer and takes a lot of time and is inefficient. Penetration crushing rod 140 is preferably made to dig into the rotation. To this end, the control circuit controls the motor 152 of the external rotating means 150 to be operated in synchronization with the operation of the hydraulic pressure supply device 240.

While the motor 152 is operating, the rotational force of the motor 152 rotates the exterior 144 of the penetration crushing rod 140 through the first and

second bevel gears

154 and 153. As a result, the drill 148 at the distal end of the exterior 144 rotates to dig the ground. In this process, the vertical downward movement force of the piston rod 164 provided by the piston is the force transmission means 180, the motor support member 156, the motor 152, the first and second bevel gears (154, 153) Also transmitted to the exterior 144 through, the exterior 144 is subjected to the force to dig vertically downward. As a result, the vertical down force and the rotational force are simultaneously applied to the exterior 144, and the exterior 144 rotates and is dug into the ground. Since the vertical downward force acting on the exterior 144 and the inner tube 142 is the same force, it enters the ground at substantially the same speed. This method allows the crushing rod 140 to dig into the ground much more effectively and quickly than to dig into the vertical descending force alone.

After sufficient time has elapsed for the piston to reach the top dead center by such a flow of fluid, the control circuit closes the

valves

174 and 175 to maintain the state by preventing the flow of the fluid and the hydraulic pressure supply device 240. And control to stop the operation of the motor 152. In this state, as shown in FIG. 4, the penetration crushing rod 140 extends out of the lower surface of the housing 113 as long as possible and is maintained.

(3) 파쇄 단계(3) shredding step

In the state in which the penetrating crushing rod 140 penetrates into the ground light layer through the above process, the user presses the crushing switch S4 to instruct soil crushing.

The control circuit of the control means 190, when the switching signal is input from the crush switch (S4) at least a portion of the compressed air in the compressed air tank 120 and the chemical liquid in the chemical liquid container 130 is the inner tube of the penetration crushing rod 140 ( It is controlled to be ejected omnidirectionally through the opening 146 via 142 (see FIG. 6). To this end, the control circuit controls the valve 122 of the compressed air tank 120 and the valve 134 of the chemical liquid container 130 to be opened. The two

valves

122 and 134 may be open at the same time or the valve 134 may be opened first and then the valve 122 may be opened after a predetermined time. According to the former method, the chemical liquid and the compressed air will be mixed in the inner tube 142 and ejected into the opening 146. According to the latter method, the chemical liquid will be filled in the inner tube 142 first, and then the compressed air will push the chemical liquid out. Will be ejected.

Since the air in the compressed air tank 120 is compressed at a high pressure, it is ejected at a very high speed through the opening 146 at 360 degrees. As if an explosion occurred in the ground, the ground rises and falls a little, and then it is broken very finely into the layer. In the process, the chemical mixes evenly between the crushed soil. Fracture of the transverse layer and the addition of chemicals (liquid ratio and / or soil modifier) occur simultaneously. Soil is crushed in an area of approximately 1.5 to 2.5 m radius per crushing. When crushed, the soil that bounces up, the housing 113 is partially blocked. If you make the lower surface 113 wider, it will be able to prevent more securely.

(4) 복귀 단계(4) return step

At the end of the shredding step, the user presses the retraction switch S5. The control circuit controls the piston to return from the top dead center to the bottom dead center when the signal of the retraction switch S5 is input. That is, the control circuit causes (i) the bidirectional pump functioning as the hydraulic supply device 240 to rotate in the opposite direction as the infiltration step, and (ii) the hydraulic circuits 172-1, 176, 162, 177, 172. -2) indicates the opening of all

valves

174, 175. The fluid in the hydraulic circuit then moves in the opposite direction as during the infiltration step, moving the piston toward the bottom dead center. Thereby, the piston rod 164 and the components directly or indirectly integrated therewith move upwards in the mode vertical. Therefore, the inner tube 142 of the penetration crushing rod 140 is also pulled up by the stroke of the piston.

Since the gear support member 188 and the bearing 189 are coupled to the piston rod 164 through the force transmission means 180 and the motor support member 156, they are synchronized when the piston rod 164 moves vertically upward. They move together vertically upwards. In this process, the second bevel gear 153 is caught up in the vertically rising bearing (189) to be lifted up, and eventually the appearance 144 of the penetration crushing rod 140 also the piston rod 164 and the inner tube 142 Together with the stroke of the piston.

Through such a process, the subsoil crusher 100 is returned to its original position. In this process, the motor 152 may be driven to allow the exterior 144 to rise while rotating. In most cases, because the surrounding soil is crushed, the exterior 144 will be able to exit even if it is pulled straight up without rotation.

The user can move through several points of the soil to be shredded, and perform four steps of preparation, infiltration, shredding, and returning for each point. As described above, the subsoil crusher 100 of the present invention effectively penetrates the hard hard layer by pressing the rotating crushing rod 140 at a desired point of the translucent layer with mechanical force, and then pressurizes the compressed air and the chemical with high pressure into the ground. At the same time, it ejects and breaks down the transdermal layer, while at the same time supplying chemicals evenly to the ground.

On the other hand, the inner tube 142 of the penetrating crushing rod 140, unlike the above embodiment directly connected to the compressed air tank 120, other members (for example, chemical liquid container 130, piston rod 164, force transmission member) (182), etc.) to allow direct lifting from the member directly. Even in this case, the inner tube 142 is to be connected to the compressed air tank 120 and the chemical liquid container 130 to be kept the same.

It may be directly connected to the lower portion or the force transmission member 182 of the chemical container (130). When the inner tube 142 is coupled to the chemical liquid container 130, the chemical liquid container 130 and the compressed air tank 120 may be interchanged with each other.

In addition, the hydraulic cylinder is only one example of the vertical lifting means (160). Instead of the hydraulic cylinder, another mechanism that functions substantially the same may be used to implement the vertical lifting means. That is, while being supported by the housing 110, while providing a sufficient force necessary to penetrate or retreat the penetration crushing rod 140 in the ground while moving in the vertical direction by a desired distance or stretched by a desired length in accordance with the control signal If the mechanism is to be used as a vertical lifting means (160). Such a mechanism may, for example, consist of a motor, gears, and a rod member corresponding to the piston rod 164.

Although the inner tube 142 of the penetration crushing rod 140 has been described as being directly coupled to the compressed air tank 120, the inner tube 142 is a vertical lifting means 160, the compressed air tank 120, the chemical liquid container 130 At least one of the force transmission member 182 and / or the coupling member 186 also serving as a coupling member may be coupled to receive the vertical lifting force generated by the vertical lifting means 160. In this case, too, the compressed air tank 120 and the chemical liquid container 130 are connected to each other, and the coupling with the external appearance 144 may be substantially the same as described above.

While the invention has been described above with reference to the embodiments shown in the drawings, it is merely exemplary. Those skilled in the art from the described embodiments will appreciate that various modifications and equivalent other embodiments are possible. Therefore, the true scope of protection of the present invention will be defined by the appended claims and technical details.

The present invention can be used as a farming machine for injecting fertilizers or soil improvers into farmland while crushing the soil layer.
