Description

Technical Field

[0001] This invention relates to the field of check valve technology for drilling, specifically to a steering structure for an adjustable rice transplanter. Background Technology

[0002] A rice transplanter is an agricultural machine used to plant rice seedlings into paddy fields. During planting, a mechanical claw first removes several rice seedlings from the seedbed and plants them into the soil. To maintain a right angle between the seedbed and the ground, the front end of the mechanical claw must move in an elliptical curve. The movement is accomplished by a planetary mechanism using rotary or variable gears, while a forward engine simultaneously drives these mechanical components.

[0003] Rice transplanters are more efficient than manual labor, but when they reach the edge of the field, the limited length of the machine means that the vehicle must first lift the transplanting equipment, then turn, and then lower the equipment. This process often results in significant differences in the spacing between seedlings. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a steering structure for an adjustable rice transplanter, including 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, and further including:

[0005] The pressure mechanism is fixedly connected to the side wall of the vehicle and is used to position and limit the vehicle's position.

[0006] The control mechanism is slidably connected to the inner wall of the pressure mechanism to increase the contact force between the pressure mechanism and the soil.

[0007] The steering mechanism is fixedly connected to the inner wall of the control mechanism and is used to automatically disconnect the power supply to the pressure mechanism after the steering is completed.

[0008] In operation, the seedlings are first placed inside the rice transplanter, and the vehicle then moves the transplanter through the mud to complete the basic transplanting process.

[0009] Preferably, the pressure mechanism includes:

[0010] The drive assembly is fixedly connected to the side wall of the vehicle by fasteners;

[0011] The fastener includes an electric push rod that is fixedly connected to the top of the vehicle, and a push rod is slidably connected to the inner wall of the electric push rod;

[0012] The contact assembly is fixedly connected to the side wall of the vehicle via a sliding member;

[0013] The sliding component includes a fixed cylinder that is fixedly connected to the side wall of the vehicle, and a sliding tube that is slidably connected to the inner wall of the fixed cylinder;

[0014] The push rod drives the sliding tube to slide down the inner wall of the fixed cylinder through the control mechanism, and forces the sliding tube to insert into the mud layer soil, so that the vehicle can only rotate around the sliding tube.

[0015] Preferably, the control mechanism includes:

[0016] The pressure assembly is slidably connected to the inner wall of the sliding tube via a pressure-applying component;

[0017] The pressure-applying component includes a sliding plate that is slidably connected to the inner wall of the sliding tube, and a spring is fixedly connected to the bottom of the sliding plate;

[0018] The control component is slidably connected to the inner wall of the sliding tube via a clamping element;

[0019] The clamping component includes a groove formed on the inner wall of the sliding tube, a rotating plate rotatably connected to the inner wall of the groove, and a snap-fit ​​block fixedly connected to the side wall of the rotating plate.

[0020] The top of the sliding plate is rotatably connected to the top of the push rod, and the sliding plate can only slide up and down along the inner wall of the sliding tube, without being able to rotate.

[0021] Preferably, the steering mechanism includes:

[0022] The auxiliary component is fixedly connected to the top of the sliding plate by a positioning element;

[0023] The positioning component includes a contact plate fixedly connected to the top of the sliding plate, a mounting plate fixedly connected to the side wall of the push rod, a slide rail fixedly connected to the side wall of the mounting plate, and an electric wire fixedly connected to the top of the slide rail.

[0024] The connecting component is slidably connected to the inner wall of the slide rail via an electrical connector;

[0025] The electrical connector includes a slide rod that is slidably connected to the inner wall of the slide rail, and a conductive metal block is fixedly connected to the side wall of the slide rod. A groove is provided in the center of the conductive metal block.

[0026] When the equipment is in normal use, the conductive metal block will connect the circuit between the wires, allowing the equipment to function properly. However, when the slide bar slides, the groove will disconnect the circuit connection between the wires.

[0027] Preferably, the drive assembly includes a spring 1 fixedly connected to the top of the sliding tube, and the end of the spring 1 away from the sliding tube is fixedly connected to the bottom of the electric actuator.

[0028] When the sliding tube slides downwards, the spring will deform and accumulate mechanical power.

[0029] Preferably, the contact assembly includes a contact block slidably connected to the inner wall of the bottom through hole of the sliding tube, and the top of the contact block is fixedly connected to the bottom of the second spring;

[0030] As the sliding tube slides downwards, the contact block will first come into contact with the mud, and drive the sliding tube to break through the mud, water, mud, soil layer and finally the sand and gravel layer. As the contact block can no longer move downwards, it will move upwards.

[0031] Preferably, the pressure assembly includes a universal joint fixedly connected to the bottom of the sliding plate, a sliding rod fixedly connected to the bottom of the universal joint, and the side wall of the sliding rod slidably connected to the side wall of the sliding tube.

[0032] When the sliding plate moves downward, it drives the sliding rod to slide downward along the inner wall of the sliding tube through the universal joint and inserts into the sand layer, thus restricting the rotation of the sliding tube.

[0033] Preferably, the control component includes a spring sheet fixedly connected to the side wall of the latching block, and a push rod rotatably connected to the top of the contact block, with one end of the push rod away from the contact block rotatably connected to the inner wall of the rotating plate;

[0034] When the contact block moves upward, it will drive the rotating plate to rotate around the connection point via the push rod.

[0035] Preferably, the auxiliary component includes a spring three fixedly connected to the top of the slide rail, with one end of the spring three away from the slide rail fixedly connected to the top of the slide rod;

[0036] When the slide bar slides along the inner wall of the slide rail, it will force the spring to deform and accumulate potential energy, which will provide mechanical power during the subsequent reset.

[0037] The connecting component includes a grounding block that is fixedly connected to the inner wall of the slide rail;

[0038] Under normal operating conditions, the contact block and the conductive metal block are in contact, and the wires are connected through the contact block and the conductive metal block. After the slide bar completes its sliding motion, the contact block and the conductive metal block are separated.

[0039] The present invention has the following beneficial effects:

[0040] (1) This invention addresses the problem that after a vehicle completes a turn, the gap between the seedlings that are close together will vary greatly due to the unevenness of the field. After ensuring that the vehicle can no longer move the rice transplanter forward, the front wheels are rotated in the direction of the unplanted seedlings and rotated to the maximum angle. Then the speed of the rear wheels is increased until the speed reaches the maximum value. At this time, due to the pressure mechanism restricting the vehicle's forward movement, and the mud and water in the muddy ground reducing the friction between the rear wheels and the ground, the vehicle drives the rice transplanter to rotate in the direction of the front wheels. Due to the restriction of the pressure mechanism, the vehicle and the rice transplanter will rotate around the pressure mechanism and complete the turn of the rice transplanter after rotating 180 degrees. By applying the above components, the difficulty of turning the equipment is reduced. After the vehicle and the rice transplanter complete the turn, the original distance between L and U is K. After the turn, the distance between the original position of L and the new position of L is 2K, which is equal to the original distance between the seedlings. This ensures that the distance difference between the seedlings is small after the equipment completes the turn.

[0041] (2) This invention utilizes the characteristic of the vehicle rotating around the pressure mechanism. A steering mechanism is installed inside the device. After the pressure mechanism is fixed, the sliding tube will no longer rotate, and the sliding tube will cause the sliding plate to stop rotating. However, when the vehicle rotates, it will cause the push rod and mounting plate to rotate. At this time, as the mounting plate rotates, as... Figure 9 As shown, the mounting plate will drive the sliding rod to rotate synchronously, and at this time, position G will contact position H, forcing the sliding rod to slide along the inner wall of the slide rail. At the same time, the conductive metal block will move away from the grounding block, so that the power supply of the wire is physically disconnected. When the wire no longer provides power to the electric push rod, the electric push rod will lose power. At this time, the spring will release potential energy, driving the sliding tube to slide upward and away from the mud. The plane of the mounting plate and the plane of the contact plate are 180 degrees. Through the application of the above components, after the equipment completes the turning, the pressure mechanism will quickly separate from the mud, and the unrestrained vehicle will drive the rice transplanter forward and re-enter the rice transplanting stage.

[0042] (3) This invention utilizes the characteristic of the push rod driving the sliding plate downwards. A control component and a contact block are installed inside the device. When the sliding tube drives the contact block downwards, if the bottom of the contact block is silt, the resistance encountered by the contact block as it moves downwards will be small, and this resistance cannot drive the contact block upwards. However, when the contact block contacts the sand and gravel at the bottom, the resistance encountered by the contact block increases. At this time, as the top sliding tube continues to move downwards, the resistance encountered by the contact block at the bottom will increase, generating an upward sliding tendency. Figure 8As shown, when the contact block moves upward, it forces the rotating plate to rotate around the connection point via the push rod. This causes the latching block to tend to move away from the sliding plate. After the latching block moves away from the sliding plate, the sliding plate will move downward and compress the second spring and the contact block to continue moving downward. During this process, the sliding plate will push the four sliding rods outward along the inner wall of the sliding tube and insert them into the surrounding soil. This prevents the sliding tube from rotating when the vehicle rotates around the pressure mechanism, thus ensuring the measurement accuracy of the equipment.

[0043] (4) During the turning process of the equipment, the sliding tube is stationary while the electric push rod is rotating. Therefore, while the spring is deformed under pressure, it will also be subjected to a torsion of 180 degrees. After the torsion, the spring will accumulate potential energy. When the push rod loses power, the spring will drive the sliding tube to slide upward. At the same time, the potential energy of the torsion will also drive the push rod and the mounting plate to reset, so that the contact plate and the mounting plate no longer contact each other. At this time, the spring will drive the sliding rod to reset synchronously, so that the circuit of the wire is connected again. Subsequently, the staff will reconnect the wire, causing the electric push rod to reverse. The push rod will drive the sliding plate to move upward, and the top of the sliding plate will contact the bottom inclined surface of the buckle block. Finally, the sliding plate will re-enter the buckle inner wall of the buckle block. Through the application of the above components, the equipment can quickly enter the working state and adapt to fields with small cross-sections. Attached Figure Description

Detailed Implementation

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Example 1, please refer to Figure 1 - Figure 8 This invention relates to a steering structure for an adjustable rice transplanter, comprising a vehicle 13, a 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, and further comprising:

[0060] Pressure mechanism 1 is fixedly connected to the side wall of vehicle 13 and is used to position and limit the position of vehicle 13.

[0061] Control mechanism 2 is slidably connected to the inner wall of pressure mechanism 1 to increase the contact force between pressure mechanism 1 and soil;

[0062] Steering mechanism 3 is fixedly connected to the inner wall of control mechanism 2 and is used to automatically disconnect the power supply of pressure mechanism 1 after steering is completed.

[0063] Before use, the vehicle 13 is driven to the field and 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.

[0064] Pressure mechanism 1 includes:

[0065] Drive assembly 11 is fixedly connected to the side wall of vehicle 13 by fasteners;

[0066] The fastener includes an electric push rod 111 fixedly connected to the top of the vehicle 13, and a push rod 112 slidably connected to the inner wall of the electric push rod 111.

[0067] Contact component 12 is fixedly connected to the side wall of vehicle 13 via a sliding member;

[0068] The sliding component includes a fixed cylinder 121 fixedly connected to the side wall of the vehicle 13, and a sliding tube 122 slidably connected to the inner wall of the fixed cylinder 121;

[0069] 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.

[0070] Control mechanism 2 includes:

[0071] Pressure assembly 21 is slidably connected to the inner wall of sliding tube 122 via a pressure-applying component;

[0072] The pressure-applying component includes a sliding plate 211 that is slidably connected to the inner wall of the sliding tube 122, and a spring 212 is fixedly connected to the bottom of the sliding plate 211;

[0073] Control component 22 is slidably connected to the inner wall of sliding tube 122 via a clamping member;

[0074] The clamping component includes a groove 221 formed in the inner wall of the sliding tube 122, a rotating plate 222 rotatably connected to the inner wall of the groove 221, and a snap-fit ​​block 223 fixedly connected to the side wall of the rotating plate 222.

[0075] To address the issue that after the vehicle completes a turn, the unevenness of the field can cause significant differences in the gaps between the tightly packed rice seedlings, the equipment is equipped with a pressure mechanism 1 and a control mechanism 2. When the equipment reaches the required turning position, the power line 314 is connected, causing the electric push rod 111 to drive the push rod 112 downward. The push rod 112 drives the sliding tube 122 to slide downward synchronously through the sliding plate 211, the latching block 223, and the rotating plate 222. At this time, the sliding tube 122 will slide downward along the inner wall of the fixed cylinder 121, break through the silt layer and reach the sand layer. Then the sliding tube 122 continues to move downward, so that most of the sliding tube 122 is buried in the sand, and the end is buried inside the gravel.

[0076] Steering mechanism 3 includes:

[0077] Auxiliary component 31 is fixedly connected to the top of sliding plate 211 by a positioning member;

[0078] The positioning component includes a contact plate 311 fixedly connected to the top of the sliding plate 211, a mounting plate 312 fixedly connected to the side wall of the push rod 112, a slide rail 313 fixedly connected to the side wall of the mounting plate 312, and a wire 314 fixedly connected to the top of the slide rail 313.

[0079] The connecting component 32 is slidably connected to the inner wall of the slide rail 313 via an electrical connector;

[0080] The electrical connection component includes a slide rod 321 that is slidably connected to the inner wall of the slide rail 313. A conductive metal block 322 is fixedly connected to the side wall of the slide rod 321. A groove 323 is provided at the center of the conductive metal block 322.

[0081] In this process, after ensuring that vehicle 13 can no longer move rice transplanter 14 forward, the front wheel 15 is rotated in the direction of the unplanted rice seedlings and rotated to the maximum angle. Then, the speed of the rear wheel 16 is increased until the speed reaches the maximum value. At this time, due to the pressure mechanism 1 restricting the forward movement of vehicle 13, and the mud and water in the muddy ground reducing the friction between the rear wheel 16 and the ground, vehicle 13 drives rice transplanter 14 to rotate in the direction of the front wheel 15. Due to the restriction of pressure mechanism 1, vehicle 13 and rice transplanter 14 will rotate around pressure mechanism 1 and complete the rotation of rice transplanter 14 after rotating 180 degrees. Through the application of the above components, the difficulty of equipment rotation is reduced. After vehicle 13 and rice transplanter 14 complete the rotation, the original distance between L and U is K. After the rotation, the distance between the original position of L and the new position of L is 2K, which is equal to the original distance of the seedlings. This ensures that the distance difference between the seedlings is small after the equipment completes the rotation.

[0082] Example 2, please refer to Figure 6 - Figure 11The present invention is a steering structure for an adjustable rice transplanter. Based on Example 1, the drive assembly 11 includes a spring 113 fixedly connected to the top of the sliding tube 122, and the end of the spring 113 away from the sliding tube 122 is fixedly connected to the bottom of the electric push rod 111.

[0083] When the sliding tube 122 slides downward, the spring 113 will deform and accumulate mechanical power.

[0084] The contact assembly 12 includes a contact block 123 that is slidably connected to the inner wall of the bottom through hole of the sliding tube 122, and the top of the contact block 123 is fixedly connected to the bottom of the second spring 212.

[0085] When the sliding tube 122 slides downward, the contact block 123 will first come into contact with the mud and drive the sliding tube 122 to break through the mud, water, mud, soil layer and then the sand and gravel layer. As the contact block 123 can no longer move downward, it will move upward.

[0086] The pressure assembly 21 includes a universal joint 213 fixedly connected to the bottom of the sliding plate 211. A sliding rod 214 is fixedly connected to the bottom of the universal joint 213. The side wall of the sliding rod 214 is slidably connected to the side wall of the sliding tube 122.

[0087] The design of the contact block 123 effectively prevents the sliding rod 214 from being inserted into sandy soil, thus preventing the sliding rod 214 from being inserted into silt and failing to effectively limit the rotation of the sliding tube 122, and ensuring the stable operation of the equipment.

[0088] The control component 22 includes a spring sheet 224 fixedly connected to the side wall of the latch block 223, and a push rod 225 rotatably connected to the top of the contact block 123. The end of the push rod 225 away from the contact block 123 is rotatably connected to the inner wall of the rotating plate 222.

[0089] Utilizing the characteristic of the push rod 112 driving 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 comes into contact with 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 8As 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.

[0090] The auxiliary component 31 includes a spring 315 fixedly connected to the top of the slide rail 313, and the end of the spring 315 away from the slide rail 313 is fixedly connected to the top of the slide rod 321.

[0091] During the device's rotation, the sliding tube 122 remains stationary, while the electric push rod 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 push rod 112 loses power, the spring 113 causes the sliding tube 122 to slide upwards, and the torsional potential energy also causes the push rod 112 and the mounting plate 312 to reset, thus 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.

[0092] The connecting component 32 includes a grounding block 324 that is fixedly connected to the inner wall of the slide rail 313;

[0093] 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 9As 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.

[0094] 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.

[0095] 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.

[0096] To address the issue of significant differences in spacing between rice seedlings after a turn due to uneven terrain, a pressure mechanism 1 and a control mechanism 2 are installed inside the equipment. When the equipment reaches the required turning position, the power line 314 is connected, causing the electric push rod 111 to move the push rod 112 downwards. The push rod 112, through the sliding plate 211, the latching block 223, and the rotating plate 222, simultaneously drives the sliding tube 122 downwards. At this point, the sliding tube 122 slides downwards along the inner wall of the fixed cylinder 121, breaking through the silt layer and reaching the sand layer. The sliding tube 122 continues to move downwards until most of it is buried in the sand, with its end embedded in gravel. After ensuring that the vehicle 13 can no longer move the rice transplanter 14 forward, the front wheel 15 is turned towards the direction where rice seedlings have not yet been transplanted. After rotating to the maximum angle, the speed of the rear wheel 16 will be increased until the speed reaches the maximum value. At this time, due to the pressure mechanism 1 restricting the forward movement of the vehicle 13, and the mud and water in the mud reducing the friction between the rear wheel 16 and the ground, the vehicle 13 drives the rice transplanter 14 to turn in the direction of the front wheel 15. However, due to the restriction of the pressure mechanism 1, the vehicle 13 and the rice transplanter 14 will rotate around the pressure mechanism 1. After rotating 180 degrees, the rice transplanter 14 will complete the turning. Through the application of the above components, the difficulty of turning the equipment is reduced. After the vehicle 13 and the rice transplanter 14 complete the turning, the original distance between L and U is K. After the turning, the distance between the original position of L and the new position of L is 2K, which is equal to the original distance of the seedlings. This ensures that the distance difference between the seedlings is small after the equipment completes the turning.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.
