Description

Technical Field

[0001] This utility model relates to the field of soil loosening machine technology, specifically a soil loosening machine with adjustable loosening depth. Background Technology

[0002] Current soil loosening equipment has many limitations and cannot meet the diverse needs of soil loosening operations. Traditional small soil loosening machines are mostly designed with a fixed loosening depth, which cannot be flexibly adjusted according to actual scenarios (such as shallow loosening before sowing, inter-row cultivation during crop growth, and deep tillage for land improvement). If different depths of soil loosening are required, equipment or parts need to be replaced, which is cumbersome and increases costs. Some soil loosening machines with adjustable depth have complex adjustment structures, which often rely on multiple sets of gears or hydraulic devices. This not only results in high manufacturing costs but also makes it easy for adjustment failures to occur due to soil impurities, making maintenance difficult. Meanwhile, traditional soil tillers generally lack effective protective structures, and soil and gravel fly during the loosening process, which can easily cause safety hazards to operators. In addition, the flying debris can easily adhere to the motor and transmission parts, shortening the service life of the equipment. Furthermore, most small soil tillers are lightweight and are prone to tipping over due to reaction forces when deep tilling or when soil resistance is high, which can lead to work interruption, affect loosening efficiency and safety, and make them unsuitable for the high-efficiency operation needs of home gardening, small farmland and other scenarios. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a soil loosening machine with adjustable loosening depth to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A soil loosening machine with adjustable loosening depth includes: Support plate, L-shaped plate, baffle, roller, motor, roller shaft, U-shaped frame, U-shaped plate, locking bolt, insert rod and counterweight; L-shaped plates are fixedly welded to the outer side of each support plate. A baffle is fixedly installed between two L-shaped plates. Rollers are rotatably connected inside the two support plates. Motors are fixedly installed on the outer side of the L-shaped plates. Rollers are fixedly installed at the output ends of the two motors. Multiple U-shaped frames are fixedly welded to the outer side of the rollers. U-shaped plates are slidably connected inside the multiple U-shaped frames. Locking bolts are threadedly connected inside the U-shaped frames and fit against the outer side of the U-shaped plates. Insert rods are fixedly installed on the outer side of the baffles. Counterweights are inserted on the outer side of the insert rods and fit against the outer side of the baffles.

[0005] Preferably, the baffle is L-shaped.

[0006] Preferably, the U-shaped plate can slide inside the U-shaped frame, and the position of the U-shaped plate can be fixed or adjusted by twisting the locking bolt.

[0007] Preferably, the insertion rod is used in conjunction with the counterweight to increase the weight of the device.

[0008] Preferably, the motor drives the roller to rotate at high speed, which in turn drives the U-shaped frame to rotate at high speed to perform soil loosening operations.

[0009] Preferably, it also includes a power supply device for driving the motor, the power supply device being electrically connected to the motor.

[0010] Preferably, the outer surface of the roller is provided with anti-slip texture to increase the friction when the device moves.

[0011] Preferably, both the U-shaped frame and the U-shaped plate are made of high-strength wear-resistant materials.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This adjustable soil loosening machine allows for flexible adjustment of the loosening depth to meet diverse needs: By sliding the U-shaped plate within the U-shaped frame and fixing it with locking bolts, the extension length of the U-shaped plate can be easily adjusted, thereby changing the loosening depth. It can meet the differentiated needs for loosening depth in different scenarios (such as shallow loosening before sowing, deep tillage and soil improvement), making it highly applicable.

[0013] 2. This adjustable soil loosening depth soil loosening machine is safe to operate and provides adequate protection for the equipment: The L-shaped baffle can effectively block the mud and gravel splashed during the soil loosening process, which not only avoids the safety threat of debris to the operator, but also reduces the adhesion of mud and gravel to key components such as motors and rollers, reduces the risk of component failure, and ensures stable operation of the equipment.

[0014] 3. This adjustable soil loosening machine ensures stable soil loosening and avoids the risk of tipping over: The outer rod of the baffle works in conjunction with the counterweight to increase the overall weight of the device, optimize the center of gravity distribution, and counteract the lateral reaction force of the soil on the U-shaped frame and U-plate during soil loosening, preventing the device from tipping over, ensuring smooth soil loosening operation, and improving work safety and efficiency.

[0015] 4. This adjustable soil loosening machine is easy to move and has high soil loosening efficiency: the rollers connected inside the support plate reduce the friction between the device and the ground, and the operator can easily push the device to move. With the motor driving the rollers to drive the U-shaped frame and U-shaped plate to rotate at high speed to crush the soil, it can quickly complete large-area soil loosening operations, which greatly improves efficiency compared with manual soil loosening.

[0016] 5. This adjustable soil loosening depth soil loosening machine has durable core components and a long service life: The U-shaped frame and U-shaped plate are made of high-strength wear-resistant materials, which can resist soil friction, compression and impact, reduce component wear, extend the service life of core working components, reduce later maintenance and replacement costs, and ensure long-term stable operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to the following: Figs. 1-3 , A soil loosening machine with adjustable loosening depth includes: Support plate 1, L-shaped plate 2, baffle 3, roller 4, motor 5, roller shaft 6, U-shaped frame 7, U-shaped plate 8, locking bolt 9, insert rod 10 and counterweight 11; L-shaped plates 2 are fixedly welded to the outer side of the support plate 1. A baffle 3 is fixedly installed between two L-shaped plates 2. Rollers 4 are rotatably connected inside the two support plates 1. Motors 5 are fixedly installed on the outer side of the L-shaped plates 2. Rollers 6 are fixedly installed at the output ends of the two motors 5. Multiple U-shaped frames 7 are fixedly welded to the outer side of the rollers 6. U-shaped plates 8 are slidably connected inside the multiple U-shaped frames 7. Locking bolts 9 are threadedly connected inside the U-shaped frames 7 and fit against the outer side of the U-shaped plates 8. Insert rods 10 are fixedly installed on the outer side of the baffle 3. Counterweights 11 are inserted on the outer side of the insert rods 10 and fit against the outer side of the baffle 3. Specifically, the overall structural support and mobile foundation: the support plate 1 serves as the core support component of the device, forming a stable frame through the L-shaped plate 2 fixedly welded on the outside. The L-shaped plate 2 also provides an installation carrier for the baffle 3 and the motor 5. The rollers 4 rotatably connected inside the two support plates 1 can reduce the friction between the device and the ground, making it easier for operators to push the device to move in the area to be loosened, thus ensuring the mobility of the loosening operation. Soil loosening power transmission and execution: The motor 5 fixed on the outside of the L-shaped plate 2 is the power source. After starting, its output end drives the roller 6 to rotate at high speed. Multiple U-shaped frames 7 fixedly welded on the outside of the roller 6 rotate synchronously with the roller 6. At this time, the pushing device moves, and the rotating U-shaped frames 7 can insert into the soil and break up the soil clods, thus initially realizing the soil loosening function. Soil loosening depth adjustment mechanism: The U-shaped plate 8, which is slidably connected inside the U-shaped frame 7, is the key component for adjusting the soil loosening depth. When it is necessary to increase the soil loosening depth, loosen the locking bolt 9 threaded onto the U-shaped frame 7. At this time, the U-shaped plate 8 can slide along the inside of the U-shaped frame 7 and extend out. After adjusting to the target depth, tighten the locking bolt 9 again. The soil loosening depth is locked by the compression and fixation of the U-shaped plate 8 by the bolt. Conversely, retracting the U-shaped plate 8 and locking it can reduce the soil loosening depth. Device stability assurance: The insertion rod 10 fixed on the outside of the baffle 3 is used to install the counterweight 11. Inserting the counterweight 11 into the insertion rod 10 and attaching it to the baffle 3 can increase the overall weight of the device and reduce the risk of the device overturning due to the lateral force generated by the interaction between the U-shaped frame 7, U-shaped plate 8 and the soil during the loosening process, thus ensuring the stable operation of the loosening operation. In this embodiment: the baffle 3 is L-shaped; Specifically, the baffle 3 adopts an L-shaped design. Its horizontal part can block the mud and gravel that splashes to the side of the device when the roller 6 and U-shaped frame 7 rotate, and its vertical part can block the debris that splashes to the rear of the device. Compared with the flat baffle 3, the L-shaped structure can expand the protection range, avoid the mud and gravel that splashes to the operator and prevent the debris from adhering to the motor 5, roller 4 and other components, thus reducing the impact of debris on the normal operation of the device. In this embodiment: the U-shaped plate 8 can slide inside the U-shaped frame 7, and the position of the U-shaped plate 8 can be fixed or adjusted by twisting the locking bolt 9; Specifically, the sliding of the U-shaped plate 8 within the U-shaped frame 7 provides a movable basis for depth adjustment, while the locking bolt 9 locks the position of the U-shaped plate 8 through "threaded connection + compression fixation". When the locking bolt 9 is loosened, the compression force of the bolt on the U-shaped plate 8 disappears, and the U-shaped plate 8 can slide freely to adjust the extension length. When the locking bolt 9 is tightened, the end of the bolt fits tightly against the outer wall of the U-shaped plate 8, using friction and compression force to limit the sliding of the U-shaped plate 8, ensuring that the U-shaped plate 8 will not shift due to soil resistance during the loosening process, thus ensuring the stability of the loosening depth. In this embodiment: the insertion rod 10 is used in conjunction with the counterweight 11 to increase the weight of the device; Specifically, during the soil loosening process, when the U-shaped frame 7 and U-shaped plate 8 are inserted into the soil and rotated, the soil will exert a reaction force on them, which may cause the center of gravity of the device to shift. The insertion rod 10 serves as the mounting carrier for the counterweight 11. The weight of the counterweight 11 increases the overall inertia of the device, counteracts the effect of the soil reaction force on the center of gravity of the device, and reduces the probability of tipping over. At the same time, the counterweight 11 is installed close to the baffle 3, which can make the weight distribution closer to the center of gravity of the device, further optimize the center of gravity position, and improve the operational stability. In this embodiment: the motor 5 drives the roller 6 to rotate at high speed, which in turn drives the U-shaped frame 7 to rotate at high speed to loosen the soil. Specifically, after the motor 5 is powered on, it converts electrical energy into mechanical energy, which drives the roller 6 to rotate at high speed through the rotation of the output end. The roller 6 is fixedly connected to the U-shaped frame 7, so the U-shaped frame 7 rotates synchronously with the roller 6. When the rotating U-shaped frame 7 and the extended U-shaped plate 8 are inserted into the soil, they will cut and break the soil, and at the same time push the device to move, so that the broken soil forms a loose layer, and finally achieves the function of loosening the soil. In this process, the power of the motor 5 is efficiently transmitted through the path of the output end of the motor 5, the roller 6, and the U-shaped frame 7, ensuring the torque and speed required for loosening the soil. In this embodiment: it also includes a power supply device for driving the motor 5, the power supply device being electrically connected to the motor 5; Specifically, the operation of motor 5 requires electrical energy. Power supply devices not shown, such as lithium battery packs and external power interfaces, are electrically connected to motor 5 through wires to provide a stable current to motor 5. The presence of the power supply device enables motor 5 to continuously output power, ensuring that roller 6 and U-shaped frame 7 maintain high-speed rotation and meet the continuous power requirements of soil loosening operations. At the same time, if a rechargeable lithium battery pack is used, the portability of the device can be improved, making it suitable for different working scenarios, such as fields without external power. In this embodiment: the outer surface of the roller 4 is provided with anti-slip texture to increase the friction when the device moves; Specifically, the anti-slip texture on the outer surface of roller 4 can increase the friction between roller 4 and the ground; when the device is moved to loosen the soil, especially on wet and soft soil surfaces, the anti-slip texture can prevent roller 4 from slipping, ensuring that the operator can smoothly control the direction and speed of the device's movement, preventing the loosening path from deviating due to roller 4 slipping, and ensuring the uniformity of the loosening area. In the embodiment: both the U-shaped frame 7 and the U-shaped plate 8 are made of high-strength wear-resistant materials; Specifically, during the soil loosening process, the U-shaped frame 7 and U-shaped plate 8 are in direct contact with the soil and must withstand the friction, compression and impact of the soil. They are made of high-strength wear-resistant materials such as high manganese steel and wear-resistant alloy steel, which can improve the deformation resistance, high strength and wear resistance of the components, reduce the wear of components caused by soil friction, extend the service life of the U-shaped frame 7 and U-shaped plate 8, and avoid frequent replacement of damaged components, which would affect the soil loosening efficiency. Working principle: When using this adjustable soil loosening machine, first place the device on the ground to be loosened, start the motor 5 on the outside of the L-shaped plate 2, the motor 5 drives the roller 6 to rotate at high speed, the roller 6 drives the multiple U-shaped frames 7 fixed on the outside to rotate synchronously, pushing the device to move through the roller 4 connected to the support plate 1. The U-shaped frame 7 and the U-shaped plate 8 slidably connected inside insert into the soil and break up the soil clods to achieve soil loosening. When it is necessary to adjust the soil loosening depth, loosen the locking bolt 9 threaded on the U-shaped frame 7, slide the U-shaped plate 8 to adjust the extension length, and then tighten the locking bolt 9 to fix it. The baffle 3 set in the L-shape is fixed between the two L-shaped plates 2 to block the splashed soil and gravel. The counterweight 11 is inserted into the rod 10 fixed on the outside of the baffle 3, which can increase the weight of the device, prevent it from tipping over during soil loosening, and ensure stable operation. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
