Description

Technical Field

[0001] The utility model relates to a deep loosening shovel technology, in particular to a bionic air-blowing deep loosening shovel. Background Art

[0002] Subsoiling is a core technology in conservation tillage, possessing crucial practical significance for improving soil structure and increasing its water storage capacity. However, the structural characteristics and operating environment of existing subsoiling shovels result in poor soil-breaking ability, high resistance, and high energy consumption, significantly reducing the economic benefits of conservation tillage. Currently, researchers at home and abroad are primarily exploring methods such as bionics, vibration, lubrication, air pressure, and layering to reduce subsoiling resistance. To further enhance this reduction, some researchers are also experimenting with combining multiple approaches to reduce tillage resistance.

[0003] For example, based on the characteristics of low-energy and high-speed digging of burrowing rabbits, Zhao Jiale innovatively designed a bionic energy storage-profile-like deep plowing device based on structural bionics and motion bionics, realizing coupled bionic design. The results of field verification tests showed that compared with traditional vibration deep plowing devices, the deep plowing fuel consumption was reduced by 26.5% to 29.2%, and the deep plowing resistance was reduced by 19.9% ​​to 27.2%; Bai Jingfeng combined bionic drag reduction technology with vibration drag reduction technology to study the vibration drag reduction effect of the bionic deep plowing shovel. The field test results showed that the drag reduction effect of the vibration bionic deep plowing shovel can reach 13.05% to 18.94%, with an average drag reduction of 15.71%, and the drag reduction effect is obvious.

[0004] It can be seen that the rational use of bionic design in subsoilers can effectively achieve drag reduction. However, existing bionic designs for subsoilers are mostly focused on chisel-type subsoilers. Research on the soil-breaking, drag-reducing, and wear-resistant properties of wing-shaped subsoilers with larger soil contact areas, especially pneumatic wing-shaped subsoilers with added air blowing functions, is relatively lacking. Summary of the Invention

[0005] The utility model aims to provide a complex coupled bionic air-blowing deep loosening shovel, which improves the soil breaking ability and drag reduction effect of the airfoil deep loosening shovel through bionic design, so as to solve the problems existing in the existing airfoil deep loosening shovel.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a bionic air-blowing deep loosening shovel, comprising a shovel body, a wing shovel, and a guard shovel, wherein the guard shovel is arranged in the middle of the rear part of the shovel body and extends upward, and the wing shovels are symmetrically arranged on the left and right sides of the shovel body and extend to both sides, and an air-blowing mechanism is installed on each wing shovel. The shovel body includes a shovel tip at the front and a shovel blade at the rear, wherein the soil-facing surface I of the shovel tip is a smooth curved surface that is upwardly convex, with a high center and smoothly lowered on the left and right sides, and the slope of the center line at the top of the soil-facing surface I decreases linearly from front to back; the soil-facing surface II of the shovel blade is a smooth curved surface that is high in the middle and low on both sides, with a front portion smoothly connected to the soil-facing surface I of the shovel tip and a rear portion smoothly connected to the guard shovel, and the slope of the center line at the top of the soil-facing surface II increases linearly from front to back.

[0007] In the above technical solution, the subsoiler used has an air blowing mechanism. During subsoiling operations, it can apply high-pressure air to the soil to break up large clods and simultaneously increase the air content within the soil. Furthermore, a bionic design is used to further enhance its soil-breaking ability during movement. The shovel tip is designed based on the external characteristics of the badger's claws. The upwardly raised, smooth, soil-facing surface (I) can divert soil to both sides during forward movement, thereby reducing resistance. This design facilitates the shovel tip's entry into the soil while also preventing excessive soil reaction, thereby better controlling the subsoiler's soil-entry depth and avoiding longitudinal vibration during subsoiling. The shovel blade is designed based on the internal characteristics of the badger's claws. Its curved structure is sharp and wear-resistant, with low resistance, effectively improving soil-breaking performance. This solution, based on the badger's proficiency in burrowing, studies the movement and shape characteristics of the claws during burrowing, reorganizing these characteristics and utilizing them in the subsoiler, thereby effectively improving the subsoiler's soil-breaking performance and increasing tillage efficiency.

[0008] As a preferred solution, the front of the wing shovel is provided with a series of raised armor plates I, which are arranged in a shingle-like pattern from front to back. The working environment of the deep plowing shovel is located in the soil. During operation, the top surface of the wing shovel is arranged obliquely forward, and its surface has a large contact area with the soil, requiring high-speed continuous operation. During this process, gravel, stones, etc. in the soil cause serious wear and tear on the deep plowing shovel. This solution is based on the biological characteristics of pangolins and sets armor plates I on the surface of the wing shovel. These armor plates I can effectively improve the wear resistance of the wing shovel. There are tiny gaps between the armor plates arranged in a shingle-like pattern. High-pressure gas will spread across the upper surface of the wing shovel along these gaps, which can not only increase the blasting range, but also reduce the resistance to the wing shovel, thereby further reducing the wear and tear on the wing shovel. During deep plowing, the protective shovel will also be subject to significant wear and tear. Therefore, it is preferred to set armor plates II on the left and right sides of the protective shovel in the same manner. The armor plates II are also arranged in a shingle-like pattern from front to back, thereby improving the wear resistance of the deep plowing shovel as a whole.

[0009] As a preferred solution, tail plates are provided at the rear of the shovel body in a bilaterally symmetrical manner. The tail plates extend upward to the rear edge of the shovel guard, downward to the root of the wing shovel and extend to the bottom of the wing shovel, and form a mounting position with at least the top open between the two tail plates, which is used to mount the shovel legs. Preferably, the lower portion of the tail plate extends forward to the middle of the back portion connected to the shovel body, and the mounting position extends forward and forms an extension position on the back portion of the shovel body. The lower portion of the shovel legs is mounted in the mounting position between the tail plates and is located behind the shovel guard. During operation, the shovel legs will not hinder the flow of soil and therefore will not increase operating resistance. In addition, the shovel legs used have shovel fingers that are inserted into the extension position. The shovel fingers cooperate with the extension position to limit the upward movement of the shovel legs and provide upward support to the deep plowing shovel, thereby ensuring the installation stability of the deep plowing shovel.

[0010] After the deep plowing shovel is installed on the shovel legs, it needs to be fixed. It is preferred to set coaxial bolt holes at the rear of the two tail plates and equip them with mounting bolts. The rear of the shovel legs used should be provided with prefabricated holes or prefabricated notches opposite to the bolt holes. Therefore, after the shovel legs are installed in place, the shovel legs can be fixed by passing the mounting bolts through the bolt holes and the prefabricated holes or prefabricated notches, and then tightening the bolts, thereby preventing the deep plowing shovel from falling off during operation.

[0011] As a preferred embodiment, the air blowing mechanism includes an air nozzle mounted on the front of the wing shovel, and also includes a three-way air distribution pipe assembly; the air distribution pipe assembly is a metal pipe, including a main pipe centrally arranged behind the mounting position, the lower end of the main pipe connected to a branch pipe, the two ends of the branch pipe are respectively connected to a branch pipe, and the two branch pipes are symmetrically distributed on the back of the wing shovel. The three-way air distribution pipe assembly can realize the purpose of simultaneously supplying air to two air nozzles with one high-pressure air pipe, wherein the main pipe is centrally arranged and located behind the shovel leg during operation, so that the high-pressure air pipe can be placed in close contact with the rear side of the shovel leg, which is beneficial to protect the high-pressure air pipe from wear; during operation, the shovel face of the wing shovel tilts forward, and the soil passes over the front of the wing shovel. Therefore, placing the branch pipe on the back of the wing shovel can not only avoid the branch pipe increasing resistance, but also effectively reduce the wear on the branch pipe.

[0012] As a preferred solution, a longitudinally penetrating mounting hole is provided on the wing shovel; the branch pipe is fitted to the back of the wing shovel, and its end is a mounting port with an internal thread, which is opposite to the mounting hole, and the air jet passes through the mounting hole and is threadedly connected to the mounting port, which is convenient for production and assembly, as well as for replacement of parts.

[0013] As a preferred embodiment, the air distribution duct assembly is installed independently; a clamping member is provided at the rear of the tailgate, secured thereto by mounting bolts and having a fixing portion that engages with the air distribution duct assembly, thereby securing the air distribution duct assembly at the rear. The clamping member preferably includes symmetrically arranged clamping arms that are mounted on both sides of the rear of the tailgate and have fixing holes that are aligned with the bolt holes. The rear portion of the clamping arm is an upwardly tilted hook, and the fixing portion is formed at the front of the hook. After the shovel leg is installed, the clamping member is first clamped to the rear of the tailgate, with the fixing hole aligned with the bolt hole. At this point, the fixing portion of the hook engages with the air distribution duct assembly, and the mounting bolts are then tightened, thereby simultaneously securing the shovel leg and the clamping member.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figure 1-3 This is an embodiment of the present invention, a bionic air-blowing deep-plowing shovel. The deep-plowing shovel adopts a bionic design. According to the characteristics of badgers being good at digging holes and pangolins having strong defensive capabilities, bionic design elements suitable for deep-plowing shovels are extracted from badger claws and pangolin scales, respectively, thereby effectively improving the soil-breaking performance and friction resistance of the deep-plowing shovel. Combined with the air-blowing function, a multi-element coupling bionic air-blowing deep-plowing shovel is obtained that can operate efficiently, has a long service life, and can effectively improve the soil environment. Therefore, its use can effectively improve the economic benefits of deep-plowing farming. Figure 1 and Figure 2 It can be seen that the bionic air-blowing deep plowing shovel includes a shovel body 1, a wing shovel 2 and a protective shovel 3, wherein the protective shovel 3 is arranged in the middle of the rear part of the shovel body 1 and extends obliquely upward and rearward, the wing shovels 2 are symmetrically arranged on the left and right sides of the shovel body 1 and extend to both sides, and air blowing mechanisms are installed on the wing shovels 2 on both sides.

[0025] First, the bionic design based on the badger's claws and toes focuses on the soil-facing surface of the shovel body 1. Specifically, the shovel body 1 includes a shovel tip a at the front and a shovel blade b at the rear, wherein the soil-facing surface I of the shovel tip a is a smooth curved surface that convexes upward, the middle part of the soil-facing surface I is high, and the left and right sides smoothly decrease, and the slope of the center dividing line at the top of the soil-facing surface I decreases linearly from front to back; the soil-facing surface II of the shovel blade b is also a smooth curved surface that is high in the middle and low on both sides, the front part of which is smoothly connected to the soil-facing surface I of the shovel tip a, and the rear part is smoothly connected to the shovel guard 3, and the slope of the center dividing line at the top of the soil-facing surface II increases linearly from front to back, so the side projection of the shovel blade b is the same as the arc-shaped claw blade of the badger's claw.

[0026] Based on the shovel body 1 of the above structure, during deep plowing operations, the smooth soil-facing surface I that protrudes upward at the shovel tip a can guide the soil to both sides when moving forward, thereby reducing resistance. This design makes it easier for the shovel tip a to enter the soil without being subjected to excessive reaction force from the soil, thereby better controlling the soil-entering depth of the deep plowing shovel and avoiding the phenomenon of longitudinal shaking during deep plowing; the arc-shaped soil-facing surface II of the shovel blade b is sharp and wear-resistant, with low resistance, which can effectively improve the soil-breaking performance.

[0027] Regarding the bionic design for wear resistance, this embodiment welds armor plates on both the wing shovel 2 and the guard shovel 3 according to the biological characteristics of the pangolin. Figure 2 A series of raised armor plates I201 are set on the front of the wing shovel 2. These armor plates I201 are distributed in a shingle-like manner from front to back. During operation, the top surface of the wing shovel 2 is tilted forward, and its surface has a large contact area with the soil. It also needs to operate continuously at high speed. In this process, gravel, stones, etc. in the soil cause serious wear and tear on the deep plowing shovel. The armor plates I201 set can effectively improve the wear resistance of the wing shovel 2. There are tiny gaps between the armor plates distributed in a shingle-like manner. High-pressure gas will spread along these gaps and spread over the upper surface of the wing shovel 2, which can not only increase the blasting range, but also reduce the resistance of the wing shovel 2, thereby further reducing the wear and tear of the wing shovel 2. Similarly, armor plates II301 are set on the left and right sides of the protective shovel 3 in the same way. The armor plates II301 are also distributed in a shingle-like manner from front to back, thereby improving the wear resistance of the deep plowing shovel as a whole.

[0028] In addition to the wing shovel 2 and the guard shovel 3, the shovel body 1 is also provided with a tail plate 10 that is connected to the wing shovel 2 and the guard shovel 3. Figure 2 and Figure 3 It can be seen that two tail plates 10 are provided at the rear of the shovel body 1 in a bilaterally symmetrical manner. The tail plates 10 extend upward to connect the rear edge of the shovel guard 3, and downward to connect the root of the wing shovel 2 and extend to the bottom of the wing shovel 2. Figure 3It can also be seen that the lower portion of the tail plate 10 extends forward to connect to the middle of the back of the shovel body 1. The two tail plates 10 are arranged in parallel, forming a mounting position 11 between them, which is open at the top, bottom, and rear. The lower portion of this mounting position 11 extends forward to form an extension position 1101 on the back of the shovel body 1, and bolt holes 12 are provided on the rear of the tail plate 10. The shovel legs used in this embodiment match the shape of the mounting position 11, and have a shovel finger portion that inserts forward into the extension position 1101. They also have prefabricated holes that are aligned with the bolt holes 12. After the shovel legs are installed in place, they are secured with mounting bolts 6. During deep plowing operations, since the lower part of the shovel leg 14 is installed in the installation position 11 between the tail plates 10 and is located behind the protective shovel 3, the lower part of the shovel leg will not hinder the flow of soil, that is, it will not reduce the efficiency and deep plowing effect of the deep plowing shovel; in addition, the shovel finger cooperates with the extension position 1101, which can not only limit the upward movement of the shovel leg, but also provide upward support force to the deep plowing shovel, thereby ensuring the installation stability of the deep plowing shovel.

[0029] Regarding the air blowing mechanism used in this embodiment, Figure 1-3 It can be seen that it includes an air nozzle 4 installed on the front of the wing shovel 2, and also includes a three-way air distribution pipe assembly 5 arranged below the wing shovel 2, wherein the three-way air distribution pipe assembly 5 is used to realize that one high-pressure air pipe supplies air to the two air nozzles 4 at the same time. Figure 7 The diagram shows the state of the deep plowing shovel when in use. It can be seen that the high-pressure air pipe 15 that supplies air to the air distribution pipe assembly 5 is located behind the shovel leg 14, so the high-pressure air pipe 15 will not be damaged during operation.

[0030] Specifically, the air distribution pipe assembly 5 used is a metal pipe, including a main pipe 501 centrally arranged behind the installation position 11, the lower end of the main pipe 501 is connected to a horizontally arranged branch pipe 502, and the two ends of the branch pipe 502 are respectively connected to a branch pipe 503, and the two branch pipes 503 are symmetrically distributed on the back of the wing shovel 2, and are connected from Figure 3 It can be seen that the back of the wing shovel 2 is provided with a raised structure for limiting the branch pipe 503, and the middle part of the raised structure is a groove that matches the branch pipe 503. The entire air blowing mechanism of this embodiment can be disassembled and assembled separately. Figure 5 It can be seen that a longitudinally penetrating mounting hole 203 is provided on the wing shovel 2, and the end of the branch pipe 503 is a mounting port 504 with an internal thread. After the branch pipe 503 is clamped in the groove of the raised structure, the mounting port 504 is opposite to the mounting hole 203, and the air nozzle 4 passes through the mounting hole 203 and is threadedly connected to the mounting port 504. Since the air nozzle 4 is pressed against the top edge of the mounting hole 203 after being fixed, it can play a role in fixing the front end of the branch pipe 503.

[0031] Regarding the fixation of the rear part of the three-way air pipe assembly 5, Figure 1 - Figure 3It can be seen that a clamping member 7 for clamping the air pipe assembly 5 is provided at the rear of the tail plate 10. Figure 6 and Figure 7 , the mounting part 7 has a symmetrically arranged clamping arm 701, the two clamping arms 701 are fixedly connected by a connecting plate 704, and a raised positioning head 705 is provided on the inner side of the clamping arm 701; the clamping arm 701 is clamped on both sides of the rear part of the tail plate 10, and has a fixing hole 702 that is directly opposite to the bolt hole 12. The rear part of the clamping arm 701 is an upwardly tilted hook body 703, and a semicircular clamping position for clamping the shunt pipe 502 is formed at the front part of the hook body 703. After the shovel leg is installed in place, the clamping part 7 is clamped on the rear part of the tail plate 10 by pushing forward horizontally and aligning the fixing hole 702 with the bolt hole 12. At this time, the clamping position of the hook body 703 clamps the shunt pipe 502 from the rear, and at the same time, the positioning head 705 on the inner side of the clamping arm 701 is embedded in the positioning notch 13 (such as Figure 4 As shown in FIG, since the positioning notch 13 clamps the positioning head 705, when the mounting bolt 6 is fixed, the entire clamping member 7 cannot be displaced relative to the tail plate 10, so the rear portion of the air distribution pipe assembly 5 can be stably fixed.

[0032] To sum up, in this embodiment, the deep plowing shovel is designed biomimetically so that the air-blown deep plowing shovel has the characteristics of badger claws and pangolin scales. Such a complex coupling design enables the deep plowing shovel to have excellent soil-breaking performance and improves farming efficiency. In addition, the coupling design of the air-blowing function and the scales allows the high-pressure gas to spread along the gaps between the scales and spread over the upper surface of the wing shovel 2, which can not only increase the range of action of the high-pressure gas, but also reduce the resistance of the wing shovel 2 by forming a gas protection layer on the surface of the wing shovel 2, thereby further reducing the wear of the wing shovel 2. At the same time, since the high-pressure gas has a blasting effect on more soil, the air content of the soil is significantly increased, which is of great significance for improving the soil tillage layer structure, improving the soil water storage capacity, etc., and can effectively improve the economic benefits of deep plowing.
