[0002] The existing grain silos have uneven grain surfaces after grain is put into the silos and need to be leveled. However, manual leveling is time-consuming and labor-intensive. If the grain surface collapses, people may be buried in the grain, which is very dangerous. Therefore, a leveling robot is currently available to replace manual operations for subsequent standardized management, thereby eliminating the dangers of manual operations.

[0003] Typically, grain leveling robots are used to level a variety of grain types, such as rice, wheat, corn, soybeans, soy beans, and mung beans. However, due to the varying sizes, weights, and frictional properties of each grain, different types or sizes of leveling robots are often required to complete the leveling operation. Using the same leveling robot can lead to inefficient leveling of some grains. Utility Model Content

[0014] In one embodiment, the distance from the outer edge to the sleeve is D2, and D2 satisfies 60 mm ≤ D2 ≤ 100 mm.

[0015] In one embodiment, the axial length of the sleeve is L, and L satisfies 150 mm ≤ L ≤ 350 mm.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] The grain surface in existing granaries is often uneven and needs to be turned over to accommodate more grain. If the grain surface collapses during manual leveling, people may be buried in the grain, which is very dangerous. Therefore, a leveling robot suitable for various types of grain is now available to replace manual operations, thus eliminating the dangers of manual operations.

[0038] Typically, multi-grain leveling robots are used to turn multiple grain types, such as rice, wheat, corn, soybeans, soy beans, and mung beans. However, due to the varying sizes, weights, and frictional forces of each grain, different types or sizes of multi-grain leveling robots are often required to complete the leveling operation. Using the same multi-grain leveling robot can lead to slow forward movement and poor turning efficiency when turning some grains.

[0039] In view of this, the present invention proposes a warehouse-closing robot 100 suitable for various types of grains, wherein the mass g of the warehouse-closing robot 100 suitable for various types of grains satisfies 15kg≤g≤30kg, and the purpose is to efficiently turn over various types of grains through the warehouse-closing robot 100 suitable for various types of grains.

[0040] See also Figures 1 to 3 In one embodiment of the present invention, the warehouse closing robot 100 suitable for various types of grain includes a body 1, a drive motor 2 and a turbine assembly 3, wherein the body 1 includes a chassis 12; the drive motor 2 is installed on the body 1; the turbine assembly 3 is transmission-connected to the drive motor 2, and the turbine assembly 3 includes a shaft 31 and a turbine 33 sleeved on the shaft 31, the shaft 31 is located on the lower side of the chassis 12, the distance between the axis of the shaft 31 and the chassis 12 is D1, and D1 satisfies 50mm≤D1≤80mm, and the turbine 33 includes a sleeve 331 and a spiral blade 332 connected to the outer periphery of the sleeve 331, and the spiral blade 332 extends from one end of the sleeve 331 toward the other end opposite to the sleeve 331.

[0041] It should be noted that the body 1 is the outer shell of the warehouse-leveling robot 100, which is suitable for handling various types of grain. The body 1 is assembled from an upper shell 11 and a bottom plate 12, facilitating the installation of batteries, circuit boards, and other electronic components. The body 1 includes a main body and two mounting portions extending outward from opposite sides of the main body. The mounting portions are used to mount the drive motor 2.

[0042] Therefore, in this embodiment, the warehouse-leveling robot 100 suitable for handling multiple grain types is equipped with two drive motors 2 and two turbine assemblies 3. The two drive motors 2 are mounted on two mounting portions, respectively. Specifically, the drive motors 2 are mounted within the mounting portions and have motor shafts that drive the turbine assemblies 3 to rotate. Therefore, the two turbine assemblies 3 are directly or indirectly connected to the motor shafts. In this embodiment, to enable the warehouse-leveling robot 100 suitable for handling multiple grain types to turn and change its movement speed, a reducer 4 is provided that is directly connected to the motor shafts. The reducer 4 is in turn connected to the turbine assemblies 3, thereby adjusting the rotational speed of the turbine assemblies 3, either increasing or decreasing the rotational speed of the turbine assemblies 3. The reducer 4 is an existing speed-changing device that can achieve the above-mentioned functions, so the reducer 4 will not be described in detail. In this embodiment, the drive motors 2 are placed perpendicular to the turbine assemblies 3. The reducer 4 changes the rotational torque of the motor shaft, thereby achieving rotation of the turbine assemblies 3.

[0043] See also Figure 6 It can be understood that the turbine assembly 3 of the warehouse-leveling robot 100, which is suitable for handling various grain types, is used to turn grain with a higher surface area, thereby maintaining a consistent grain surface within the silo. The turbine assembly 3 also enables the warehouse-leveling robot 100, which is suitable for handling various grain types, to move across the grain surface. Specifically, the turbine assembly 3 comprises a shaft 31, a sleeve 32, a turbine 33, and an end cap 34. The shaft 31 is directly connected to the reducer 4, which in turn drives the sleeve 32 and turbine 33 to rotate together. The reducer 4 is located in the middle of the shaft 31, so two turbines 33 are provided on opposite sides of the reducer 4. The sleeve 32 is provided to reduce the weight of the turbine 33. Furthermore, if the turbine 33 were directly connected to the shaft 31, significant friction would occur between the shaft 31 and the turbine 33. The sleeve 32 reduces this friction between the shaft 31 and the turbine 33. Among them, the turbine 33 includes a sleeve 331 and a spiral blade 332 connected to the sleeve 331, wherein the spiral blade 332 extends from one end of the sleeve 331 toward the other end. In this way, the spiral blade 332 can have better structural strength, and the design of this spiral blade 332 enables the intelligent leveling robot 100 suitable for various types of grains to have a better grain leveling rate.

[0044] It is understandable that when the mass of the intelligent warehouse-leveling robot 100 for multiple grain types is too large, the turbine 33 of the intelligent warehouse-leveling robot 100 for multiple grain types may be overly buried in the grain in the granary, or even the intelligent warehouse-leveling robot 100 for multiple grain types may be buried by the grain, thereby affecting the grain leveling rate of the intelligent warehouse-leveling robot 100 for multiple grain types. When the mass of the intelligent warehouse-leveling robot 100 for multiple grain types is too small, the grain leveling depth of the turbine 33 of the intelligent warehouse-leveling robot 100 for multiple grain types may be too shallow, thereby reducing the grain leveling efficiency of the intelligent warehouse-leveling robot 100 for multiple grain types. Therefore, the mass g of the intelligent warehouse-leveling robot 100 for multiple grain types is selected to be between 15kg and 30kg. g can be any value among 16kg, 18kg, 20kg, 22kg, 24kg, 26kg, 28kg, and 30kg, and is not specifically limited here.

[0045] For further details, please refer to Figure 2 If the chassis 12 of the intelligent warehouse-leveling robot 100 applicable to a variety of grain types contacts the grain surface, it may slow down the grain-leveling rate of the intelligent warehouse-leveling robot 100. Therefore, the shaft 31 of the turbine assembly 3 is set on the lower side of the chassis 12. In this way, all or most of the turbine 33 of the turbine assembly 3 are located on the lower side of the chassis 12. In order to ensure that the chassis 12 does not contact the grain surface, the distance D1 between the chassis 12 and the shaft 31 is set to be between 50mm and 80mm. When D1 is between 50mm and 80mm, compared with D1 less than 50mm and D1 greater than 80mm, the intelligent warehouse-leveling robot 100 applicable to a variety of grain types has a good grain-leveling rate and depth, and has higher work efficiency. D1 can be any value of 50mm, 55mm, 65mm, 70mm, 75mm, or other values ​​within the range of 50mm to 80mm, and is not specifically limited here.

[0046] In one embodiment, see Figure 3 The distance between the blade edge 332c of the spiral blade 332 and the axis of the shaft 31 is D2, and D2 satisfies 60mm≤D2≤100mm.

[0047] It should be noted that the distance D2 from the outer edge 332b to the sleeve 331 should not be less than 60mm, otherwise the grain leveling depth of the sleeve 331 is not good within this range. D2 should also not be greater than 100mm. Considering that in the above embodiment, the distance between the spiral blade 332 and the chassis 12 is preferably 50mm to 80mm, if the size of the spiral blade 332 is too large, the grain surface will contact the chassis 12, thereby causing greater friction between the chassis 12 and the fuselage 1, affecting the grain leveling rate of the spiral blade 332. Moreover, if the blade thickness is constant, increasing the blade size may affect the structural strength of the blade. Therefore, the distance D2 from the blade outer edge 332b to the sleeve 331 is preferably within the range of 60mm to 100mm. D2 can be any value among 60mm, 70mm, 80mm, 90mm, and 100mm, or other values ​​within the range of 60mm to 100mm, and is not specifically limited here.

[0048] Further, in one embodiment, please continue to refer to Figure 3 The axial length of the sleeve 331 is L, and L satisfies 150mm≤L≤300mm.

[0049] It can be understood that the axial length of the sleeve 331 has a great influence on the rotation shape of the spiral blade 332 on the sleeve 331. If the length of the sleeve 331 is too short, the spiral blade 332 will be too concentrated in the axial direction of the sleeve 331, so that the spiral blade 332 cannot carry too much grain in the process of turning the grain, which will reduce the grain leveling efficiency of the intelligent flattening robot 100 suitable for various grain types. If the axial length of the sleeve 331 is too long, the spiral blade 332 will be too dispersed in the axial direction of the sleeve 331, reducing the turning force of the spiral blade 332, thereby also reducing the turning efficiency of the intelligent flattening robot 100 suitable for various grain types. Therefore, it is better to set L within the range of 150mm to 300mm. Among them, L can be any value among 150mm, 200mm, 250mm, 300mm, or other values ​​within 150mm to 300mm. Setting the axial length of the sleeve 331 within 220mm to 280mm is the preferred range of the axial length of the sleeve 331, and the specific value is not specifically limited here.

[0050] As follows, some data within the limited range of the mass g of the intelligent liquidation robot 100 applicable to various types of grain, some data within the limited range of the distance D1 between the axis of the shaft 31 and the chassis 12, some data between the blade edge 332c of the spiral blade 332 and the axis of the shaft 31 D2, and some data of the axial length L of the sleeve 331 are selected to implement multiple groups and obtain the following embodiments.

[0051] Example 1: When g is 17 kg, D1 is 65 mm, D2 is 95 mm, and L is 280 mm, the following Table 1 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0053]

[0054] Example 2: When g is 22 kg, D1 is 50 mm, D2 is 95 mm, and L is 190 mm, the following Table 2 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0055] Table 2 Example 2

[0056]

[0057] Example 3: When g is 28 kg, D1 is 50 mm, D2 is 65 mm, and L is 240 mm, the following Table 3 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0058] Table 3 Example 3

[0059]

[0060] Example 4: When g is 28 kg, D1 is 80 mm, D2 is 80 mm, and L is 240 mm, the following Table 4 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0061] Table 4 Example 4

[0062]

[0063]

[0064] Example 5: When g is 22 kg, D1 is 80 mm, D2 is 80 mm, and L is 190 mm, the following Table 5 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0065] Table 5 Example 5

[0066]

[0067] Example 6: When g is 17 kg, D1 is 65 mm, D2 is 65 mm, and L is 280 mm, the following Table 6 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0068] Table 6 Example 6

[0069]

[0070] Comparative Example 1: When g is 12 kg, D1 is 35 mm, D2 is 65 mm, and L is 240 mm, the following Table 7 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0071] Table 7 Comparative Example 1

[0072]

[0073] Comparative Example 2: When g is 40 kg, D1 is 65 mm, D2 is 130 mm, and L is 400 mm, the following Table 8 shows the operation of the intelligent liquidation robot 100 suitable for various types of grain in the granary.

[0074] Table 8 Comparative Example 2

[0075]

[0076] It should be noted that the grain leveling depth and the grain leveling quality per unit time are the two values ​​that have the greatest impact on the grain leveling efficiency of the intelligent leveling robot 100 applicable to various types of grains, and the grain leveling quality per unit time can intuitively reflect the grain leveling efficiency of the intelligent leveling robot 100 applicable to various types of grains. According to the data in Tables 1 to 8 above, it can be seen that when g, D1, D2 and L are within the range specified in this embodiment, the intelligent leveling robot 100 suitable for multiple types of grains in this embodiment operates in a granary storing rice, wheat, corn, soybeans, etc., and the difference in the change of the grain leveling depth and the grain quality per unit time is small, and the difference between the wheat that is easier to turn and the rice that is more difficult to turn does not exceed 2.5t / h; and when at least part of the values ​​of g, D1, D2 and L exceed the range specified in this embodiment, the intelligent leveling robot 100 suitable for multiple types of grains in this embodiment operates in a granary storing different types of grains. At least one of the grain leveling depth and the grain quality per unit time has a large change difference, and it can be obviously seen that it will lead to too low grain leveling efficiency or too shallow grain leveling depth.

[0077] Specifically, please refer to Table 7. Since the fuselage 1 is light and the distance between the chassis 12 and the shaft 31 is too short, the spiral blade 332 is not deep enough into the grain, and the intelligent flattening robot 100 suitable for various types of grains is severely obstructed during its movement. It can be clearly seen that the flat grain quality per unit time in all types of grains is at a low level, and the flat grain quality per unit time between rice and wheat is quite different; in Table 8, since the fuselage 1 is too heavy and the axial length of the sleeve 331 is too long, the turning force of the spiral blade 332 is difficult to turn efficiently, especially when facing grains that are more difficult to turn. In Table 8, the flat grain quality per unit time between wheat and rice is quite different. Therefore, when g, L, D1 and D2 are within the limited range, the intelligent flattening robot 100 suitable for various types of grains can be efficiently used in granaries containing the above-mentioned types of grains.

[0078] The technical solution of the present invention is to set the shaft 31 of the turbine 33 assembly 3 on the lower side of the chassis 12, and limit the mass of the intelligent flattening robot 100 suitable for various types of grains to between 15kg and 30kg, limit the distance between the shaft 31 and the chassis 12 to between 50mm and 80mm, limit the distance between the blade edge 332c of the spiral blade 332 and the shaft 31 to between 60mm and 100mm, and limit the axial length of the sleeve 331 to between 180mm and 300mm, thereby reducing the friction between the chassis 12 and the grain surface, thereby ensuring that the intelligent flattening robot 100 suitable for various types of grains has a better grain leveling rate and grain leveling depth when applied to different types of grains, so that the intelligent flattening robot 100 suitable for various types of grains can be used in granaries storing various grains.

[0079] Further, in one embodiment, see Figure 2 and Figure 3 The mass g of the intelligent closing robot 100 suitable for various types of grains satisfies 16kg≤g≤28kg, D1 satisfies 60mm≤D1≤70mm, D2 satisfies 75mm≤D2≤95mm, and L satisfies 220mm≤L≤280mm.

[0080] As follows, some data within the limited range of the mass g of the intelligent liquidation robot 100 applicable to various types of grain, some data within the limited range of the distance D1 between the axis of the shaft 31 and the chassis 12, some data between the blade edge 332c of the spiral blade 332 and the axis of the shaft 31 D2, and some data of the axial length L of the sleeve 331 are selected to implement multiple groups and obtain the following embodiments.

[0081] Example 7: When g is 18 kg, D1 is 65 mm, D2 is 90 mm, and L is 270 mm, the following Table 1 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0083]

[0084] Example 8: When g is 23 kg, D1 is 60 mm, D2 is 90 mm, and L is 230 mm, the following Table 2 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0085] Table 10 Example 8

[0086]

[0087] Example 9: When g is 27 kg, D1 is 60 mm, D2 is 75 mm, and L is 250 mm, the following Table 3 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0088] Table 11 Example 9

[0089]

[0090] Example 10: When g is 27 kg, D1 is 70 mm, D2 is 82 mm, and L is 250 mm, the following Table 4 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0091] Table 12 Example 10

[0092]

[0093] Example 11: When g is 23 kg, D1 is 70 mm, D2 is 82 mm, and L is 230 mm, the following Table 5 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0094] Table 13 Example 11

[0095]

[0096] Example 12: When g is 18 kg, D1 is 65 mm, D2 is 75 mm, and L is 270 mm, the following Table 6 shows the operation of the intelligent warehouse-closing robot 100 suitable for various types of grain in the grain silo.

[0097] Table 14 Example 12

[0098]

[0099]

[0100] It should be noted that Tables 9 to 14 correspond to Tables 1 to 6 respectively. It can be clearly seen that after further limiting the values ​​of g, D1, D2 and L, the intelligent leveling robot 100 suitable for various types of grains can obtain better grain leveling depth and grain leveling rate, and the difference in grain leveling quality per unit time between rice, wheat, corn, soybeans and soybeans is further reduced. Therefore, the intelligent granary machine 100 proposed in the embodiment of the present invention has a higher grain leveling efficiency when operating in a granary storing the above-mentioned various grain crops.

[0101] In one embodiment, see Figure 4 The spiral blade 332 has a leading edge 332a and an outer edge 332b. The leading edge 332a is closer to the sleeve 331 than the outer edge 332b. The outer edge 332b and the leading edge 332a are in a chamfered transition.

[0102] It should be noted that both the leading edge 332a and the outer edge 332b are the edges of the spiral blade 332, wherein the outer edge 332b is further away from the sleeve 331 than the leading edge 332a, and the distance between the outer edge 332b and the sleeve 331 is substantially the same, while the leading edge 332a is closer to the sleeve 331 than the outer edge 332b, and the leading edge 332a extends from the sleeve 331 to the outer edge 332b. The transition between the leading edge 332a and the outer edge 332b adopts a rounded design, thereby improving the grain leveling rate and forward speed of the intelligent warehouse leveling robot 100 suitable for handling various types of grains, and also providing the transition between the leading edge 332a and the outer edge 332b with good structural strength, making it less susceptible to deformation caused by the impact of grains.

[0103] In one embodiment, see Figure 3 and Figure 5 The spiral blade 332 rotates around the sleeve 331 from one end of the sleeve 331 to the other end opposite to the sleeve 331.

[0104] It should be noted that in the above embodiment, the spiral blade 332 extends from one end of the sleeve 331 toward the other end opposite the sleeve 331. In this embodiment, the spiral blade 332 is limited to extend from one end of the sleeve 331 to the other end opposite the sleeve 331, and the spiral blade 332 rotates exactly one circle within the range of the spiral blade 332's axial extension within the sleeve 331. This improves the grain leveling efficiency of the spiral blade 332 during rotation.

[0105] In one embodiment, see Figure 2 and Figure 4 The thickness of the blade edge 332 c of the spiral blade 332 is less than the thickness of the blade root 332 d of the spiral blade 332 .

[0106] It can be understood that in order to make the spiral blade 332 have better structural strength, the thickness of the blade root 332d of the spiral blade 332 is made larger. In order to reduce the weight of the spiral blade 332 and prevent the intelligent leveling robot 100 suitable for various types of grain from sinking excessively during grain leveling operations, the thickness of the blade edge 332c of the spiral blade 332 is made smaller than the thickness of the blade root 332d of the spiral blade 332.

[0107] In one embodiment, please continue to refer to Figure 2 and Figure 4 The thickness of the spiral blade 332 gradually increases from the blade edge 332c to the blade root 332d of the spiral blade 332.

[0108] In the above embodiment, the thickness of the blade edge 332c of the spiral blade 332 is limited to be smaller than the thickness of the spiral blade 332 near the sleeve 331. Furthermore, in this embodiment, the thickness from the blade edge 332c of the spiral blade 332 to the blade root 332d of the spiral blade 332 gradually increases, so that the thickness of the spiral blade 332 has a uniform change, further enhancing the structural strength of the spiral blade 332, so that the spiral blade 332 is not easily deformed when impacted by grain.

[0109] In one embodiment, please continue to refer to Figure 2 and Figure 4 The thickness of the blade edge 332c of the spiral blade 332 is T1, and T1 satisfies 2mm≤T1≤6mm. The thickness of the blade root 332d of the spiral blade 332 is T2, and T2 satisfies 7mm≤T2≤13mm.

[0110] It can be understood that the spiral blade 332 has obvious thickness variations, so the thickness of the spiral blade 332 has a larger range, wherein the thickness at the blade edge 332c of the spiral blade 332 is approximately between 2mm and 6mm, and the thickness at the blade edge 332c of the spiral blade 332 can be any value among 2mm, 3mm, 4mm, 5mm and 6mm, or other values ​​between 2mm and 6mm, which is not specifically limited here; and the thickness of the blade root 332d of the spiral blade 332 is between 7mm and 13mm, and the thickness of the blade root 332d of the spiral blade 332 can be any value among 7mm, 8mm, 10mm, 11mm and 13mm, or other values ​​between 7mm and 13mm, which is not specifically limited here.

[0111] In one embodiment, see Figures 2 to 4The number of the spiral blades 332 is set to two, and the two spiral blades 332 are spaced apart in the circumferential direction of the sleeve 331.

[0112] Specifically, in the above embodiment, the number of spiral blades 332 can be one, two, or more, while in this embodiment, the number of spiral blades 332 is limited to two. It can be understood that two spiral blades 332 can improve the grain leveling efficiency of the intelligent flattening robot 100 applicable to a variety of grain types compared to one spiral blade 332. If the number of spiral blades 332 is set to more, the distance between adjacent spiral blades 332 will be too small, which will affect the grain leveling efficiency of the intelligent flattening robot 100 applicable to a variety of grain types and reduce its workload per unit time. Therefore, setting the number of spiral blades 332 to two is the optimal value.

[0113] In one embodiment, please continue to refer to Figures 2 to 4 The distance between the two spiral blades 332 is D3, and D3 satisfies 250mm≤D3≤450mm.

[0114] It should be noted that the distance between the two spiral blades 332 should not be too small. If the distance between the spiral blades 332 is too small, it will result in the inability to turn over more grain between the spiral blades 332, thereby affecting the workload of the intelligent grain leveling robot per unit time. Affected by the size of the sleeve 331, the distance between the two spiral blades 332 cannot be set too large. Therefore, it is better to set the distance between the two spiral blades 332 between 250mm and 450mm. D3 can be any value among 250mm, 300mm, 350mm, 400mm, and 450mm, or other values ​​within 250mm to 450mm, and no specific limitation is made here.

[0115] In one embodiment, see Figure 1 The material of the spiral blade 332 is set to be any one of magnesium-aluminum alloy, PPS and carbon fiber.

[0116] Taking into account that the intelligent warehouse-leveling robot 100 will continue to move forward while turning the grain in the granary, the spiral blade 332 needs to have sufficient structural strength. Therefore, the material of the spiral blade 332 is set to any one of magnesium-aluminum alloy, PPS or carbon fiber. The above materials have good structural strength and yield strength. The spiral blade 332 can withstand a large impact force without deformation. At the same time, carbon fiber also has a lightweight effect, which can reduce the overall weight of the intelligent warehouse-leveling robot 100 suitable for various types of grain, so that the intelligent warehouse-leveling robot 100 will not sink excessively, thereby improving the grain leveling efficiency of the intelligent warehouse-leveling robot 100.

[0117] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
