Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of check valves for drilling, in particular to a steering structure of an adjustable rice transplanter. BACKGROUND

[0002] The transplanter is an agricultural machine for transplanting rice seedlings into a rice field. When planting, a mechanical claw is used to take several rice seedlings from a seedbed and transplant them into the soil in the field. In order to maintain a right angle between the seedbed and the ground, the front end of the mechanical claw must move in an elliptical motion curve. The motion is completed by a planetary mechanism of rotating or deforming gears, and the forward engine can drive these motion mechanisms.

[0003] Compared with manual work, the efficiency of the rice transplanter has been improved. However, when the transplanter reaches the edge of the field, the vehicle needs to lift the transplanting equipment first, then turn, and then lower the transplanting equipment after completing the turning. This process often results in a large difference in the spacing between the seedlings. To solve the above problems, the following scheme is proposed. SUMMARY

[0004] To solve the above technical problems, the present application provides a steering structure of an adjustable rice transplanter, which comprises a vehicle, a transplanter rotatably connected to the side wall of the vehicle, a front wheel rotatably connected to the bottom of the vehicle, and a rear wheel rotatably connected to the bottom of the vehicle, further comprising: a pressure mechanism fixedly connected to the side wall of the vehicle for positioning and limiting the position of the vehicle; a control mechanism slidably connected to the inner wall of the pressure mechanism for increasing the contact force between the pressure mechanism and the soil; a steering mechanism fixedly connected to the inner wall of the control mechanism for automatically disconnecting the power supply of the pressure mechanism after completing the turning; In use, the seedlings are first placed in the transplanter, and the vehicle drives the transplanter to move in the mud to complete the basic transplanting process.

[0005] Preferably, the pressure mechanism comprises: a driving assembly fixedly connected to the side wall of the vehicle by a fixing piece; the fixing piece comprises an electric push rod fixedly connected to the top of the vehicle, and the inner wall of the electric push rod is slidably connected with a push rod; a contact assembly fixedly connected to the side wall of the vehicle by a sliding piece; the sliding piece comprises a fixed cylinder fixedly connected to the side wall of the vehicle, and the inner wall of the fixed cylinder is slidably connected with a sliding tube; The push rod drives the sliding tube to slide along the inner wall of the fixed cylinder downward by the control mechanism, and forces the sliding tube to insert into the soil inside the mud layer, so that the vehicle can only rotate around the sliding tube.

[0006] Preferably, the control mechanism comprises: The pressure assembly is slidably connected to the inner wall of the sliding tube by a pressing member; The pressing member comprises a sliding plate slidably connected to the inner wall of the sliding tube, and the bottom of the sliding plate is fixedly connected with a spring two; The control assembly is slidably connected to the inner wall of the sliding tube by a clamping member; The clamping member comprises a sliding groove opened in the inner wall of the sliding tube, and a rotating plate is rotatably connected to the inner wall of the sliding groove, and the side wall of the rotating plate is fixedly connected with a buckle block; The top of the sliding plate is rotatably connected with the top of the push rod, and the sliding plate can only slide up and down along the inner wall of the sliding tube and cannot rotate.

[0007] Preferably, the steering mechanism comprises: The auxiliary assembly is fixedly connected to the top of the sliding plate by a positioning member; The positioning member comprises a contact plate fixedly connected to the top of the sliding plate, and the side wall of the push rod is fixedly connected with a mounting plate, the side wall of the mounting plate is fixedly connected with a sliding rail, and the top of the sliding rail is fixedly connected with an electric wire; The connecting assembly is slidably connected to the inner wall of the sliding rail by an electrical connecting member; The electrical connecting member comprises a sliding rod slidably connected to the inner wall of the sliding rail, and the side wall of the sliding rod is fixedly connected with a conductive metal block, and a groove is opened in the center of the conductive metal block; When the device is normally used, the conductive metal block will connect the circuit between the electric wires, so that the device is normally used, and when the sliding rod slides, the groove will disconnect the circuit connection of the electric wires.

[0008] Preferably, the driving assembly comprises a spring one fixedly connected to the top of the sliding tube, and the end of the spring one away from the sliding tube is fixedly connected with the bottom of the electric push rod; When the sliding tube slides downward, the spring one will deform and accumulate mechanical power.

[0009] Preferably, the contact assembly comprises a contact block slidably connected to the inner wall of the through hole at the bottom of the sliding tube, and the top of the contact block is fixedly connected with the bottom of the spring two; When the sliding tube slides downward, the contact block will first contact the thin mud, and drive the sliding tube to break the mud water, thin mud, soil layer and sand layer, and when the contact block cannot move downward again, the contact block will move upward.

[0010] Preferably, the pressure assembly comprises a universal joint fixedly connected to the bottom of the sliding plate, the bottom of the universal joint is fixedly connected with a sliding rod, and the side wall of the sliding rod is slidably connected with the side wall of the sliding pipe. When the sliding plate moves downward, the sliding plate drives the sliding rod to slide downward along the inner wall of the sliding pipe through the universal joint and inserts into the interior of the sandy soil layer, thereby limiting the rotation of the sliding pipe.

[0011] Preferably, the control assembly comprises a spring sheet fixedly connected to the side wall of the buckle block, the top of the contact block is rotatably connected with a push rod, and the end, away from the contact block, of the push rod is rotatably connected with the inner wall of the rotating plate. When the contact block moves upward, the contact block drives the rotating plate to rotate around the connecting point.

[0012] Preferably, the auxiliary assembly comprises a spring three fixedly connected to the top of the sliding rail, and the end, away from the sliding rail, of the spring three is fixedly connected with the top of the sliding rod. When the sliding rod slides along the inner wall of the sliding rail, the spring three is forced to deform and accumulate potential energy, thereby providing mechanical power during subsequent resetting.

[0013] The connecting assembly comprises an electricity connecting block fixedly connected to the inner wall of the sliding rail. When the device is in a normal state, the electricity connecting block is in contact with the conductive metal block, at this time, the electric wire completes circuit connection through the electricity connecting block and the conductive metal block, and after the sliding rod completes sliding, the electricity connecting block and the conductive metal block are in a separated state.

[0014] The present application has the following advantages: (1) The present application aims at the problem that after the vehicle completes steering, there is a large difference in the gap between the seedlings that are close to each other due to the unevenness of the field. After ensuring that the vehicle cannot drive the rice transplanter to move forward, the front wheel is turned to the direction where the seedlings have not been transplanted and is turned to the maximum angle. Then the speed of the rear wheel is increased until the speed reaches the maximum value. At this time, the vehicle drives the rice transplanter to turn in the direction of the front wheel due to the restriction of the pressure mechanism and the friction between the rear wheel and the ground is reduced by the mud in the field. The vehicle and the rice transplanter will rotate around the pressure mechanism, and after rotating one hundred and eighty degrees, the steering of the rice transplanter is completed. Through the application of the above-mentioned assemblies, the steering difficulty of the device is reduced. After the vehicle and the rice transplanter complete steering, the distance between the original L and U is K, and the distance between the position of the original L and the position of the new L after steering is 2K, which is equal to the distance from the original seedlings. After the device completes steering, the difference between the distances of the seedlings is small.

[0015] (2) The present application utilizes the above-mentioned vehicle to generate rotation around the pressure mechanism, and sets a steering mechanism inside the device, wherein, after the pressure mechanism is fixed, the sliding tube will no longer rotate, the sliding tube drives the sliding plate to no longer rotate, and when the vehicle rotates, the push rod and the mounting plate will rotate, at this time, as shown in Figure 9 , the mounting plate will drive the slide rod to rotate synchronously, and at this time, the position of G will contact the position of H, and force the slide rod to slide along the inner wall of the slide rail, while the conductive metal block will move away from the contact block, so that the power supply of the wire is in a physically disconnected state, and when the wire no longer provides power for the electric push rod, the electric push rod will lose power, at this time, the spring will release potential energy, drive the sliding tube to slide upwards and away from the mud, and the plane of the mounting plate and the plane of the contact plate are at one hundred and eighty degrees, through the application of the above-mentioned components, after the device is steered, the pressure mechanism will quickly separate from the mud, and the vehicle without restraint will drive the rice transplanter to move forward and enter the rice transplanting link again.

[0016] (3) The present application utilizes the above-mentioned push rod to drive the sliding plate to slide downwards, and sets a control assembly and a contact block inside the device, wherein, when the sliding tube drives the contact block to slide downwards, if the bottom of the contact block is a mud part, the resistance received by the contact block when moving downwards will be smaller, and this resistance cannot drive the contact block to move upwards, and when the contact block contacts the sandstone at the bottom, the resistance received by the contact block will increase, at this time, as the top sliding tube continues to move downwards, the resistance received by the contact block at the bottom will increase, and a tendency to slide upwards is generated, as shown in Figure 8 , when the contact block moves upwards, the contact block forces the rotating plate to rotate around the connection point through the push rod, so that the buckle block generates a tendency to move away from the sliding plate, and after the buckle block moves away from the sliding plate, the sliding plate will move downwards and press spring two and the contact block to continue to move downwards, and during this process, the sliding plate will push the four sliding rods to move outward along the inner wall of the sliding tube and insert into the soil around, preventing the sliding rod from rotating the sliding tube when the vehicle rotates around the pressure mechanism, affecting the measurement accuracy of the device.

[0017] (4) the sliding pipe is in a state of not moving, and the electric push rod is in a state of rotating during the turning of the device, so that the spring one will bear torsion of a rotation angle of 180 degrees again while being deformed under pressure, and after the torsion, the spring one will accumulate potential energy, when the push rod loses power, the spring one drives the sliding pipe to slide upward, and the torsion potential energy will also drive the push rod and the mounting plate to reset, so that the contact plate is no longer in contact with the mounting plate, and at this time, the spring three will drive the sliding rod to reset synchronously, so that the circuit of the electric wire is in a connected state again, then, the worker connects the electric wire again, so that the electric push rod is reversed, the push rod drives the sliding plate to move upward, and the top of the sliding plate will be in contact with the bottom inclined surface of the buckle block, and finally the sliding plate reenters the buckle inner wall of the buckle block, through the application of the above components, the device can quickly enter the working state, and the device is suitable for fields with small cross sections.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0022] Embodiment one, please refer to Figure 1 - Figure 8 The present application is a steering structure of an adjustable rice transplanter, comprising a vehicle 13, a rice transplanter 14 rotatably connected to the side wall of the vehicle 13, a front wheel 15 rotatably connected to the bottom of the vehicle 13, and a rear wheel 16 rotatably connected to the bottom of the vehicle 13, further comprising: a pressure mechanism 1 fixedly connected to the side wall of the vehicle 13, for positioning and limiting the position of the vehicle 13; a control mechanism 2 slidably connected to the inner wall of the pressure mechanism 1, for increasing the contact force between the pressure mechanism 1 and the soil; a steering mechanism 3 fixedly connected to the inner wall of the control mechanism 2, for automatically disconnecting the power supply of the pressure mechanism 1 after steering is completed; Before use, the vehicle 13 is first driven to the field, and the push rod 112 is ensured to be in a retracted state, then the vehicle 13 drives the rice transplanter 14 to move, and the rice transplanter 14 completes the basic rice transplanting process.

[0023] The pressure mechanism 1 comprises: a drive assembly 11 fixedly connected to the side wall of the vehicle 13 by a fixing member; The fixing member comprises an electric push rod 111 fixedly connected to the top of the vehicle 13, and the inner wall of the electric push rod 111 is slidably connected with a push rod 112; The contact assembly 12 is fixedly connected at the side wall of the vehicle 13 through a sliding piece; The sliding piece comprises a fixed cylinder 121 fixedly connected at the side wall of the vehicle 13, and a sliding pipe 122 slidingly connected at the inner wall of the fixed cylinder 121; The center point position of the contact block 123 is as Figure 2 The middle u, and the position of the transplanted seedlings is L, the lateral distance between the position of L and the position of U in the rear view of the vehicle is K, and the distance between two seedlings when the transplanter 14 plants is 2K.

[0024] The control mechanism 2 comprises: The pressure assembly 21 is slidingly connected at the inner wall of the sliding pipe 122 through a pressing piece; The pressing piece comprises a sliding plate 211 slidingly connected at the inner wall of the sliding pipe 122, and a spring 212 fixedly connected at the bottom of the sliding plate 211; The control assembly 22 is slidingly connected at the inner wall of the sliding pipe 122 through a clamping piece; The clamping piece comprises a sliding groove 221 opened at the inner wall of the sliding pipe 122, a rotating plate 222 rotatably connected at the inner wall of the sliding groove 221, and a buckle block 223 fixedly connected at the side wall of the rotating plate 222; The pressure mechanism 1 and the control mechanism 2 are arranged inside the device to solve the problem that the gap between the seedlings close to each other after the vehicle completes the steering is greatly different due to the unevenness of the field. When the device reaches the position where steering is needed, the electric wire 314 is connected to make the electric push rod 111 drive the push rod 112 to move downward, and the push rod 112 drives the sliding pipe 122 to slide downward synchronously through the sliding plate 211, the buckle block 223 and the rotating plate 222. At this time, the sliding pipe 122 will slide downward along the inner wall of the fixed cylinder 121 and break through the silt layer to reach the sandy soil layer, and then the sliding pipe 122 continues to move downward so that half of the sliding pipe 122 is buried in the sandy soil and the end is buried in the sandstone.

[0025] The steering mechanism 3 comprises: The auxiliary assembly 31 is fixedly connected at the top of the sliding plate 211 through a positioning piece; The positioning piece comprises a contact plate 311 fixedly connected at the top of the sliding plate 211, an installation plate 312 fixedly connected at the side wall of the push rod 112, a sliding rail 313 fixedly connected at the side wall of the installation plate 312, and an electric wire 314 fixedly connected at the top of the sliding rail 313; The connecting assembly 32 is slidingly connected at the inner wall of the sliding rail 313 through an electric connection piece; The power contact includes a sliding rod 321 slidingly connected at the inner wall of the sliding rail 313, and a conductive metal block 322 fixedly connected at the side wall of the sliding rod 321, and a groove 323 is formed at the central position of the conductive metal block 322; Wherein, after ensuring that the vehicle 13 cannot drive the rice transplanter 14 to move forward any more, the front wheel 15 is turned to the direction of non-transplanting, and is turned to the maximum angle, and then the rotating speed of the rear wheel 16 is increased until the rotating speed reaches the maximum value, at this time, due to the restriction of the pressure mechanism 1 on the forward movement of the vehicle 13, and the mud water reduces the friction between the rear wheel 16 and the ground in the mud, which makes the vehicle 13 drive the rice transplanter 14 to turn to the direction of the front wheel 15, and the vehicle 13 and the rice transplanter 14 will rotate around the pressure mechanism 1 due to the restriction of the pressure mechanism 1, and after rotating one hundred and eighty degrees, the turning of the rice transplanter 14 is completed, through the application of the above components, the turning difficulty of the equipment is reduced, and after the vehicle 13 and the rice transplanter 14 complete the turning, the distance between the original L and U is K, and the distance between the original position of L and the new position of L after the turning is 2K, which is equal to the distance between the original seedlings, so that the difference between the distances of the seedlings after the turning of the equipment is small.

[0026] Embodiment two, please refer to Figure 6 Figure 11 The application is a steering structure of an adjustable rice transplanter, based on example one, the driving assembly 11 includes a spring one 113 fixedly connected at the top of the sliding pipe 122, and the end of the spring one 113 away from the sliding pipe 122 is fixedly connected with the bottom of the electric push rod 111. Wherein, when the sliding pipe 122 slides downward, the spring one 113 will deform and accumulate mechanical power.

[0027] The contact assembly 12 includes a contact block 123 slidingly connected at the inner wall of the through hole at the bottom of the sliding pipe 122, and the top of the contact block 123 is fixedly connected with the bottom of the spring two 212. Wherein, when the sliding pipe 122 slides downward, the contact block 123 will first contact the thin mud, and drive the sliding pipe 122 to break the mud water, thin mud, soil layer and sand layer, and when the contact block 123 cannot move downward again, the contact block 123 will move upward.

[0028] The pressure assembly 21 includes a universal joint 213 fixedly connected at the bottom of the sliding plate 211, and the bottom of the universal joint 213 is fixedly connected with a sliding rod 214, and the side wall of the sliding rod 214 is slidingly connected with the side wall of the sliding pipe 122. Wherein, the design of the contact block 123 will effectively avoid that the sliding rod 214 is inserted into the sand soil position, and prevent the sliding rod 214 from being inserted into the silt position, so as to effectively limit the turning of the sliding pipe 122 and ensure the stable operation of the equipment.

[0029] ​The control assembly 22 comprises spring sheets 224 fixedly connected to the side walls of the buckle block 223, and a push rod 225 rotatably connected to the top of the contact block 123, and one end of the push rod 225 away from the contact block 123 is rotatably connected to the inner wall of the rotating plate 222; The push rod 112 drives the sliding plate 211 to slide downward, and the control assembly 22 and the contact block 123 are arranged inside the device. When the contact block 123 slides downward under the driving of the sliding pipe 122, if the bottom of the contact block 123 is a silt part, the resistance to the downward movement of the contact block 123 is small, and the resistance cannot drive the contact block 123 to move upward. When the contact block 123 contacts the sand at the bottom, the resistance to the contact block 123 is increased. When the top sliding pipe 122 continues to move downward, the resistance to the contact block 123 at the bottom is increased, and the contact block 123 has a tendency to slide upward. Figure 8 When the contact block 123 moves upward, the contact block 123 forces the rotating plate 222 to rotate around the connecting point through the push rod 225, so that the buckle block 223 has a tendency to move away from the sliding plate 211. After the buckle block 223 moves away from the sliding plate 211, the sliding plate 211 moves downward and presses the spring 212 and the contact block 123 to continue to move downward. During this process, the sliding plate 211 pushes the four sliding rods 214 outward along the inner wall of the sliding pipe 122 and inserts them into the soil around the device, preventing the sliding rods 214 from rotating the sliding pipe 122 when the vehicle 13 rotates around the pressure mechanism 1, thereby affecting the measurement accuracy of the device.

[0030] The auxiliary assembly 31 comprises spring three 315 fixedly connected to the top of the sliding rail 313, and one end of the spring three 315 away from the sliding rail 313 is fixedly connected to the top of the sliding rod 321. During the turning process of the device, the sliding pipe 122 is in a stationary state, and the electric push rod 111 is in a rotating state. Therefore, the spring one 113 is deformed under pressure and then bears a torsion of 180 degrees. After the torsion, the spring one 113 accumulates potential energy, and when the push rod 112 loses power, the spring one 113 drives the sliding pipe 122 to slide upward, and the torsion potential energy also drives the push rod 112 and the mounting plate 312 to reset, so that the contact plate 311 is no longer in contact with the mounting plate 312. At this time, the spring three 315 drives the sliding rod 321 to reset synchronously, so that the circuit of the electric wire 314 is connected again. Then, the staff connects the electric wire 314 again, so that the electric push rod 111 reverses, and the push rod 112 drives the sliding plate 211 to move upward. The top of the sliding plate 211 contacts the inclined surface at the bottom of the buckle block 223, and finally the sliding plate 211 reenters the buckle of the buckle block 223. Through the application of the above assemblies, the device can quickly enter the standby state and adapt to the fields with small cross sections.

[0031] The connecting component 32 includes a grounding block 324 that is fixedly connected to the inner wall of the slide rail 313; Taking advantage of the characteristic that the vehicle 13 rotates around the pressure mechanism 1, a steering mechanism 3 is installed inside the equipment. After the pressure mechanism 1 is fixed, the sliding tube 122 will no longer rotate, and the sliding tube 122 will also stop rotating the sliding plate 211. However, when the vehicle 13 rotates, it will cause the push rod 112 and the mounting plate 312 to rotate. At this time, as the mounting plate 312 rotates, as... Figure 9 As shown, the mounting plate 312 will drive the sliding rod 321 to rotate synchronously, and at this time, the position of G will contact the position of H, forcing the sliding rod 321 to slide along the inner wall of the slide rail 313. At the same time, the conductive metal block 322 will move away from the contact block 324, so that the power supply of the wire 314 is physically disconnected. When the wire 314 no longer provides power to the electric push rod 111, the electric push rod 111 will lose power. At this time, the spring 113 will release potential energy, driving the sliding tube 122 to slide upward and away from the mud. The plane of the mounting plate 312 and the plane of the contact plate 311 are at an angle of 180 degrees. Through the application of the above components, after the equipment completes the turning, the pressure mechanism 1 will quickly separate from the mud, and the unrestrained vehicle 13 will drive the rice transplanter 14 to move forward and re-enter the rice transplanting stage.

[0032] One specific application of this embodiment is: before use, drive the vehicle 13 to the field and ensure that the push rod 112 is in the retracted state. Then, the vehicle 13 drives the rice transplanter 14 to move, and the rice transplanter 14 completes the basic rice transplanting process. The center point of contact block 123 is located as follows: Figure 2 In the middle u, the position for transplanting rice seedlings is L. In the rear front view position of the vehicle, the lateral distance between position L and position U is K. When the rice transplanter 14 is planting, the distance between two rice seedlings is 2K.

[0033] In view of the problem that after the vehicle completes the steering, the gap between the seedlings close to each other after the steering is completed has great difference due to the unevenness of the field, a pressure mechanism 1 and a control mechanism 2 are arranged inside the equipment, when the equipment reaches the position where steering is needed, the wire 314 is connected, so that the electric push rod 111 drives the push rod 112 to move downward, the push rod 112 drives the sliding pipe 122 to slide downward synchronously through the sliding plate 211, the buckle block 223 and the rotating plate 222, at this time, the sliding pipe 122 will slide downward along the inner wall of the fixed cylinder 121 and break through the silt layer to reach the sandy soil layer, then the sliding pipe 122 continues to move downward, so that more than half of the sliding pipe 122 is buried in the sandy soil, and the end is buried in the sandstone, after ensuring that the vehicle 13 cannot drive the rice transplanter 14 to move forward any more, the front wheel 15 is turned to the direction where the seedlings are not transplanted, and is turned to the maximum angle, then the rotating speed of the rear wheel 16 is increased until the rotating speed reaches the maximum value, at this time, the pressure mechanism 1 limits the forward movement of the vehicle 13, and the mud water in the muddy field reduces the friction between the rear wheel 16 and the ground, which makes the vehicle 13 drive the rice transplanter 14 to rotate in the direction of the front wheel 15, and the vehicle 13 and the rice transplanter 14 will rotate around the pressure mechanism 1, and after rotating one hundred and eighty degrees, the steering of the rice transplanter 14 is completed, through the application of the above components, the steering difficulty of the equipment is reduced, and after the vehicle 13 and the rice transplanter 14 complete the steering, the distance between the original L and U is K, and the distance between the position of the original L and the position of the new L after the steering is completed is 2K, which is equal to the distance from the original seedlings, so that the difference between the distances of the seedlings after the steering of the equipment is completed is small.

[0034] By using the rotating feature of the vehicle 13 around the pressure mechanism 1, a steering mechanism 3 is arranged inside the equipment, when the pressure mechanism 1 is fixed, the sliding pipe 122 will no longer rotate, the sliding pipe 122 drives the sliding plate 211 to no longer rotate, and when the vehicle 13 rotates, the push rod 112 and the mounting plate 312 will rotate, at this time, as shown in Figure 9 the mounting plate 312 will drive the sliding rod 321 to rotate synchronously, and at this time, the position of G will contact the position of H, and force the sliding rod 321 to slide along the inner wall of the slide rail 313, at the same time, the conductive metal block 322 will move away from the power contact block 324, so that the power supply of the wire 314 is in a physical power-off state, and when the wire 314 no longer provides power for the electric push rod 111, the electric push rod 111 will lose power, at this time, the spring one 113 will release potential energy, drive the sliding pipe 122 to slide upward and away from the muddy ground, and the plane of the mounting plate 312 and the plane of the contact plate 311 are at an angle of one hundred and eighty degrees, through the application of the above components, after the equipment completes the steering, the pressure mechanism 1 will quickly separate from the muddy ground, and the vehicle 13 that loses the restraint will drive the rice transplanter 14 to move forward and enter the rice transplanting link again.

[0035] Utilizing the characteristic that the push rod 112 drives the sliding plate 211 to slide downwards, a control component 22 and a contact block 123 are installed inside the equipment. When the sliding tube 122 drives the contact block 123 downwards, if the bottom of the contact block 123 is silt, the resistance encountered by the contact block 123 will be small, and this resistance will not be enough to move the contact block 123 upwards. However, when the contact block 123 contacts the sand and gravel at the bottom, the resistance encountered by the contact block 123 increases. At this time, as the top sliding tube 122 continues to move downwards, the resistance encountered by the contact block 123 at the bottom will increase, creating a tendency to slide upwards. Figure 8 As shown, when the contact block 123 moves upward, the contact block 123 forces the rotating plate 222 to rotate around the connection point via the push rod 225, causing the latching block 223 to tend to move away from the sliding plate 211. After the latching block 223 moves away from the sliding plate 211, the sliding plate 211 will move downward and compress the second spring 212 and the contact block 123 to continue moving downward. During this process, the sliding plate 211 will push the four sliding rods 214 outward along the inner wall of the sliding tube 122 and insert them into the surrounding soil. This prevents the sliding rods 214 from rotating when the vehicle 13 rotates around the pressure mechanism 1, thus avoiding the rotation of the sliding tube 122 and affecting the measurement accuracy of the equipment.

[0036] The design of the contact block 123 will effectively prevent the sliding rod 214 from being inserted into the sandy soil, thus preventing the sliding rod 214 from being inserted into the silt and failing to effectively limit the rotation of the sliding tube 122, and ensuring the stable operation of the equipment. During the device's rotation, the sliding tube 122 remains stationary, while the electric actuator 111 rotates. Therefore, while the spring 113 deforms under pressure, it also experiences a 180-degree torsion. After this torsion, the spring 113 accumulates potential energy. When the actuator 112 loses power, the spring 113 causes the sliding tube 122 to slide upwards, and the torsional potential energy also resets the actuator 112 and the mounting plate 312, preventing the contact plate 311 from contacting the mounting plate 312. At this time, spring 315 will drive slide rod 321 to reset synchronously, so that the circuit of wire 314 is connected again. Then, the staff will reconnect wire 314, causing electric push rod 111 to reverse. Push rod 112 will drive sliding plate 211 to move upward, and the top of sliding plate 211 will contact the bottom inclined surface of buckle block 223. Finally, sliding plate 211 will re-enter the buckle inner wall of buckle block 223. Through the application of the above components, the equipment can quickly enter the working state and adapt to fields with small cross-sections.
