Description

[0001] The present application belongs to the technical field of cultivation, and particularly relates to an automatic soil hole opener and a method of using the same. BACKGROUND

[0002] Cultivating seedlings in sandy soil areas can improve soil structure, increase soil organic matter content, and thus improve soil fertility and water retention capacity. Through cultivation, wind and water erosion can be reduced, soil erosion can be prevented, and sustainable use of land can be maintained. At the same time, the vegetation in sandy soil areas can also serve as a windbreak forest belt to reduce the damage of wind hazards to surrounding areas. When large-scale artificial cultivation is carried out, a large amount of manpower and material resources are consumed. When a shovel is used to dig a trench in soft sandy soil, the sandy soil may flow in all directions when the shovel is inserted due to the flowability of the sandy soil.

[0013] In the present application, a method for using an automatic soil hole opener includes the following steps:

[0014] S1: Fix the limiting pipe on the sliding holder through the plug, then connect the telescopic pipe with the drain pipe, close the control valve and open the pump. The pump continuously delivers water to the water storage main frame. The water in the water storage main frame will extrude the expansion frame, so that the expansion frame slides outward, thereby increasing the volume of the water storage main frame. As the expansion frame slides outward, the buffer spring is in a compressed state. When the expansion frame slides outward to abut against the contact sensor, the contact sensor will control the pump to stop working.

[0015] S2: turn on the hydraulic telescopic rod, the telescopic end of the hydraulic telescopic rod pulls the sliding support to move vertically downward, the sliding support pulls the secondary connection base to move vertically downward, the secondary connection base drives the sliding holder to move vertically downward through the partition, the sliding holder drives the limiting pipe to move vertically downward, and then the first pressure shovel and the second pressure shovel are inserted into the sandy soil; when the first pressure shovel and the second pressure shovel are inserted into the sandy soil, the sandy soil will exert an upward reaction force on the pressure sensor A and the pressure sensor B; when the pressure sensor B is subjected to the pressure exerted by the sandy soil, the pressure sensor B controls the control valve to open, the control valve makes the drain pipe conductive, at this time, the buffer spring in the compressed state will stretch and reset, and the expansion frame will be extruded to reset, in the process of resetting, the expansion frame will exert pressure on the water in the water storage main frame, so that the water is sprayed in a pressurized manner; the pressure sensor A will control the pressure injector to spray the water in the telescopic pipe to wet the sandy soil; further, the pressure sensor B will also be electrically connected with the plugging controller after being extruded, at this time, the plugging controller will control the plugging tab to slide upward along the outer side of the second pressure shovel, and the plugging tab and the drain port are gradually separated, at this time, the water in the telescopic pipe will be sprayed from the drain port to wet the sandy soil;

[0016] S3: in the process of sliding the sliding support downward, when the sliding support contacts the first touch sensor, the first touch sensor controls the telescopic end of the hydraulic telescopic rod to move vertically upward, and at the same time, the driving motor is turned on, at this time, the output shaft of the driving motor drives the butt gear to start counterclockwise rotation, through the meshing action with the toothed plate, the sliding holder is driven to move obliquely synchronously, so that the limiting pipe moves upward and is also subjected to an oblique tension, with the movement of the limiting pipe, the first pressure shovel gradually extends from the sandy soil, the gap between the first pressure shovel and the second pressure shovel gradually increases, and the sandy soil outside the first pressure shovel flows into the hole opening along the gap, covering the left side of the seedling body, at this time, the seedling body is biased to one side of the second pressure shovel due to the pressure of the sandy soil on the left side; when the limiting pipe drives the first pressure shovel to move upward, the upward reaction force exerted by the sandy soil on the pressure sensor A disappears, the pressure sensor A is electrically disconnected with the pressure injector, and the pressure injector stops water;

[0017] S4: when the sliding support contacts the third touch sensor, the hydraulic telescopic rod stops running, so that the hydraulic telescopic rod, the main connection base and the secondary connection base can be precisely reset;

[0018] S5: In the process of driving the first pressure shovel upward by the limiting tube, the telescopic tube in the limiting tube will slide out from the bottom of the limiting tube, when the limiting sleeve is in contact with the limiting tube, that is, the telescopic tube slides out to the maximum limit, at this time the telescopic tube drives the second pressure shovel to move upward through the limiting sleeve, and also exerts an oblique force on the second pressure shovel in the same direction as the limiting tube, which straightens the seedling body in the side deviation, and in the process of moving the second pressure shovel, the sand soil outside the second pressure shovel flows into the hole mouth along the gap, and fixes the right side of the seedling body;

[0019] S6: In the process of extracting the second pressure shovel from the sand soil, the upward reaction force of the sand soil on the pressure sensor B disappears, and the pressure sensor B is electrically disconnected with the sealing controller, at this time the sealing controller controls the sealing paddle to slide downward along the outer side of the second pressure shovel to seal the drainage hole; at the same time, when the pressure of the sand soil on the pressure sensor B disappears, the pressure sensor B controls the control valve to close, and the control valve blocks the drain pipe, at this time with the pump continuously conveying water to the water storage main frame, the water in the water storage main frame will extrude the expansion frame, so that the expansion frame slides outward, thereby increasing the volume of the water storage main frame, with the expansion frame sliding outward, the buffer spring is in compression state, when the expansion frame slides outward to abut against the contact sensor, the contact sensor will control the pump to stop working;

[0020] S7: When the sliding holder moves upward, the first limiting rod slides out of the positioning plate, and the telescopic air rod and the compression spring are in compression state, when the limiting sleeve is in contact with the second contact sensor, the second contact sensor will control the driving motor to stop running, at this time the telescopic air rod and the compression spring will stretch and reset, and the sliding holder is reset, at this time the contact surface of the first pressure shovel and the second pressure shovel restores to the maximum limit of contact, so as to facilitate the next insertion. Advantages

[0021] Compared with the prior art, the advantages of the present application are:

[0022] I. In the application, after the seedling body is placed in the hole mouth, the worker holds the handle with both hands and pulls it upward, thereby driving the limiting tube to move upward, the limiting tube drives the first pressure shovel to move upward, in the process of the first pressure shovel moving upward, the gap between the first pressure shovel and the second pressure shovel will gradually increase, the sand soil outside the first pressure shovel will flow into the hole mouth along the gap, and the left side of the seedling body is covered with soil, at this time, the seedling body will be biased to the side of the second pressure shovel under the pressure of the left sand soil; in the process of the limiting tube driving the first pressure shovel to move upward, the telescopic tube in the limiting tube will slide out from the bottom of the limiting tube, when the limiting sleeve ring contacts with the limiting tube, that is, the telescopic tube slides out to the maximum limit, at this time, the telescopic tube will drive the second pressure shovel to move upward, and the second pressure shovel will right the seedling body which is deviated to the side when moving, in the process of the second pressure shovel moving, the sand soil outside the second pressure shovel will flow into the hole mouth along the gap, and the right side of the seedling body is covered with soil.

[0023] II. In the application, when the first pressure shovel and the second pressure shovel are inserted into the sand soil, the sand soil will exert an upward reaction force on the pressure sensor B, the pressure sensor B will be in electrical connection with the plugging controller after being extruded, at this time, the plugging controller will control the plugging paddle to slide upward along the outer side surface of the second pressure shovel, the plugging paddle is gradually separated from the drainage port, at this time, the water in the telescopic tube will be sprayed out from the drainage port, and the sand soil is wetted.

[0024] III. In the application, in the process of the limiting tube driving the first pressure shovel to move upward, the shunt tube will be gradually separated from the sand soil, at this time, the upward reaction force exerted by the sand soil on the pressure sensor A disappears, the pressure sensor A is electrically disconnected with the pressure injector, and the pressure injector stops water; further, in the process of the limiting tube driving the first pressure shovel to move upward, the telescopic tube in the limiting tube will slide out from the bottom of the limiting tube, when the limiting sleeve ring contacts with the limiting tube, that is, the telescopic tube slides out to the maximum limit, at this time, under the action of the limiting sleeve ring, the telescopic tube will drive the second pressure shovel to move upward, so that the second pressure shovel is extracted from the sand soil, when the second pressure shovel is extracted from the sand soil, at this time, the upward reaction force exerted by the sand soil on the pressure sensor B disappears, the pressure sensor B is electrically disconnected with the plugging controller, at this time, the plugging controller will control the plugging paddle to slide downward along the outer side surface of the second pressure shovel, and the drainage port is plugged to reduce water waste.

[0025] IV. In the application, after the telescopic tube is slidably inserted into the limiting tube, the limiting sleeve ring is sleeved on the telescopic tube, and the limiting sleeve ring is located above the limiting tube, the limiting sleeve ring can prevent the limiting tube from sliding out of the telescopic tube when the limiting tube is lifted, and at the same time, when the first pressure shovel or the second pressure shovel needs to be replaced, the first pressure shovel and the second pressure shovel can be separated by only taking out the limiting sleeve ring and the second contact sensor.

[0026] V. In the application, the force receiving area of the first pressure shovel can be increased by the arranged treading plate. During operation, the operator can apply pressure to the treading plate with his feet, so that the first pressure shovel and the second pressure shovel can be inserted into the soil. The arranged anti-skid strip can increase the friction and prevent skidding, so that the operator can perform the planting operation.

[0027] VI. In the application, the second limiting rod can support the buffer spring and ensure the stability of the buffer spring when it is compressed or stretched, so that the middle part of the buffer spring does not deviate when it is compressed, and the expansion frame is not affected.

[0028] VII. In the application, when the pressure applied by the sand to the pressure sensor A and the pressure sensor B disappears, the pressure sensor B controls the control valve to be closed at this time, and the control valve blocks the drain pipe. At this time, as the pump continuously delivers water to the water storage main frame, the water in the water storage main frame will extrude the expansion frame, so that the expansion frame slides outward, thereby increasing the volume of the water storage main frame. As the expansion frame slides outward, the buffer spring is in a compressed state. When the expansion frame slides outward to abut against the contact sensor, the contact sensor controls the pump to stop working at this time. When the pressure sensor B is subjected to the pressure applied by the sand again, the pressure sensor B controls the control valve to be opened, and the control valve makes the drain pipe conductive at this time. The buffer spring in a compressed state will be stretched and reset, and the expansion frame will be extruded to reset. In the resetting process, the expansion frame will apply pressure to the water in the water storage main frame, so that the water is sprayed in a pressurized manner, thereby facilitating the water to be sprayed from the pressure sprayer and the drain port. The arranged pressure sensor B, control valve, control structure and pump can flexibly control the discharge of water in the water storage tank. BRIEF DESCRIPTION OF DRAWINGS

10. The method of using an automatic soil hole opener of claim 9, wherein: The method comprises the following steps: S1: the limiting pipe (6) is fixed on the sliding card seat (31) through the plug (27), then the telescopic pipe (4) is connected with the drain pipe (52), the control valve (50) is closed and the pump (62) is opened, the pump (62) continuously sends water to the water storage main frame (54), the water in the water storage main frame (54) can extrude the expansion frame (56), so that the expansion frame (56) slides outward, thereby increasing the volume of the water storage main frame (54), along with the expansion frame (56) sliding outward, the buffer spring (59) is in compression state, when the expansion frame (56) slides outward to abut with the contact inductor (61), the contact inductor (61) controls the pump (62) to stop working at this time; S2: open the hydraulic telescopic rod (34), the telescopic end of the hydraulic telescopic rod (34) pulls the sliding support (35) to move vertically downward, the sliding support (35) pulls the secondary connection base (30) to move vertically downward, the secondary connection base (30) drives the sliding card seat (31) to move vertically downward through the partition plate (46), the sliding card seat (31) drives the limiting pipe (6) to move vertically downward, thereby inserting the first pressure shovel (1) and the second pressure shovel (2) into the sand; when the first pressure shovel (1) and the second pressure shovel (2) are inserted into the sand, the sand will exert an upward reaction force on the pressure sensor A (21) and the pressure sensor B (22), when the pressure sensor B (22) is subjected to the pressure applied by the sand, the pressure sensor B (22) controls the control valve (50) to open, the control valve (50) makes the drain pipe (52) conductive, at this time, the buffer spring (59) in compression state will stretch and reset, extruding the expansion frame (56) to reset, in the process of resetting, the expansion frame (56) will exert pressure on the water in the water storage main frame (54), so that the water is sprayed in a pressurized manner; the pressure sensor A (21) will control the pressure injector (20) to spray the water in the telescopic pipe (4) to wet the sand; further, the pressure sensor B (22) is extruded and electrically connected with the plugging controller (7) at this time, the plugging controller (7) will control the plugging tab (23) to slide upward along the outer side of the second pressure shovel (2), the plugging tab (23) and the drain port (3) are gradually separated, at this time, the water in the telescopic pipe (4) will be sprayed from the drain port (3) to wet the sand; S3: In the process of sliding bracket (35) sliding down, when the sliding bracket (35) contacts the first touch sensor (38), the first touch sensor (38) controls the extension end of the hydraulic telescopic rod (34) to move vertically upward, and the driving motor (32) is started at the same time. At this time, the output shaft of the driving motor (32) drives the butt gear (41) to start counterclockwise rotation, which moves obliquely through the meshing action with the toothed plate (39), and in turn drives the sliding clamp holder (31) to move synchronously obliquely, so that the limiting tube (6) moves upward and is also subjected to an oblique tension. With the movement of the limiting tube (6), the first pressure shovel (1) gradually extends out of the sand, the gap between the first pressure shovel (1) and the second pressure shovel (2) gradually increases, and the sand on the outside of the first pressure shovel (1) flows into the hole mouth (8) along the gap to cover the left side of the seedling body. At this time, the seedling body is biased to the side of the second pressure shovel (2) due to the pressure of the sand on the left side; when the limiting tube (6) moves upward with the first pressure shovel (1), the upward reaction force of the sand on the pressure sensor A (21) disappears, the pressure sensor A (21) is electrically disconnected with the pressure injector (20), and the pressure injector (20) stops water injection; S4: When the sliding bracket (35) contacts the third touch sensor (37), the hydraulic telescopic rod (34) stops running, so that the hydraulic telescopic rod (34), the main connecting base (29) and the auxiliary connecting base (30) can be accurately reset; S5: In the process of the limiting tube (6) moving upward with the first pressure shovel (1), the telescopic tube (4) in the limiting tube (6) will slide out of the bottom of the limiting tube (6). When the limiting sleeve ring (16) contacts the limiting tube (6), i.e. the telescopic tube (4) slides out to the maximum, the telescopic tube (4) drives the second pressure shovel (2) to move upward through the limiting sleeve ring (16), and at the same time an oblique force in the same direction as the limiting tube (6) is applied to the second pressure shovel (2) to center the seedling body which is deviated to the side. In the process of moving the second pressure shovel (2), the sand on the outside of the second pressure shovel (2) flows into the hole mouth (8) along the gap to cover and fix the right side of the seedling body. S6: When the second pressure shovel (2) is extracted from the sand, the upward reaction force of the sand on the pressure sensor B (22) disappears, and the pressure sensor B (22) is electrically disconnected with the blocking controller (7). At this time, the blocking controller (7) will control the blocking paddle (23) to slide downward along the outer side of the second pressure shovel (2) to block the drain port (3); at the same time, when the pressure of the sand on the pressure sensor B (22) disappears, the pressure sensor B (22) controls the control valve (50) to close, and the control valve (50) blocks the drain pipe (52). At this time, as the pump (62) continuously delivers water into the water storage main frame (54), the water in the water storage main frame (54) will extrude the expansion frame (56) to slide outward, thereby increasing the volume of the water storage main frame (54). As the expansion frame (56) slides outward, the buffer spring (59) is in a compressed state. When the expansion frame (56) slides outward to abut against the contact sensor (61), the contact sensor (61) will control the pump (62) to stop working; S7: When the sliding holder (31) is inclined upward, the limiting rod (45) slides out of the positioning plate (48), and the telescopic air rod (47) and the compression spring (49) are in a compressed state. When the limiting sleeve ring (16) contacts the second contact sensor (28), the second contact sensor (28) will control the driving motor (32) to stop running. At this time, the telescopic air rod (47) and the compression spring (49) will be stretched and reset to reset the sliding holder (31). At this time, the contact surface of the first pressure shovel (1) and the second pressure shovel (2) returns to the maximum contact to facilitate the next insertion.
