[0036] After the grain is put into the existing granary, the grain surface is not flat and needs 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 granary robot with an end cap is currently available to replace manual operation for subsequent standardized management, thereby eliminating the danger of manual operation.

[0037] Grain storage in granaries often contains moisture and insect eggs, which can lead to rapid insect reproduction. To prevent insect growth, the granary is filled with phosphine gas. If phosphine gas enters the grain-leveling robot, it can adhere to the motor's copper wire or the copper coating on the circuit board, corroding the copper and potentially causing failure of the motor or electronic control module.

[0038] In view of this, the present invention proposes a granary robot 100 with end caps, which is used to turn over the grain in the granary so that the height of the grain in the granary is in a relatively balanced state, so that the granary can accommodate more grain.

[0039] See also Figures 1 to 3 In one embodiment of the present invention, the granary robot 100 with end caps includes a body 1, a drive device 2 and a turbine assembly 3; the drive device 2 is installed on the body 1; the turbine assembly 3 is transmission-connected to the drive device 2, and the turbine assembly 3 includes a shaft 31, a sleeve 32, a turbine 33 and an end cap 34, the sleeve 32 is sleeved on the shaft 31, the turbine 33 is hollow, the sleeve 32 is installed inside the turbine 33, and the shaft 31, the sleeve 32 and the turbine 33 rotate synchronously, the shaft 31 has an extension section 311 exposed outside the sleeve 32, and the end cap 34 is installed outside the sleeve 32 to cover the gap between the sleeve 32 and the shaft 31.

[0040] It should be noted that the body 1 is the outer shell of the grain storage robot 100 with end caps. The body 1 is composed of two upper and lower shells, which facilitate the installation of batteries, circuit boards, and other electronic components within the body 1. The body 1 includes a main body 11 and two mounting portions 12 extending outward from opposite sides of the main body 11. The mounting portions 12 are used to mount the drive device 2.

[0041] Therefore, in this embodiment, two sets of drive devices 2 and two sets of turbine assemblies 3 are provided. The two sets of drive devices 2 are respectively installed in two mounting portions 12. Specifically, the drive device 2 is configured as a drive motor, which is installed in the mounting portion 12. The drive motor has a motor shaft, which drives the turbine assembly 3 to rotate through the motor shaft. Therefore, the two sets of turbine assemblies 3 are directly or indirectly connected to the motor shaft. In this embodiment, in order to achieve the turning of the grain silo robot 100 with an end cap and change the movement speed of the grain silo robot 100 with an end cap, a reducer 4 is provided that is directly connected to the motor shaft. The reducer 4 is further connected to the turbine assembly 3, and the rotation rate of the turbine assembly 3 can be adjusted. The rotation rate of the turbine assembly 3 can be increased or decreased. The reducer 4 is an existing speed-changing device that can achieve the above-mentioned function, so the reducer 4 will not be described in detail. In this embodiment, the drive motor is placed vertically on the turbine assembly 3, and the rotation torque of the motor shaft is changed by the reducer 4, thereby achieving the rotation of the turbine assembly 3.

[0042] It is understood that the turbine assembly 3 of the grain silo robot 100 with an end cap 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 grain silo robot 100 with an end cap 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 friction between the shaft 31 and the turbine 33.

[0043] Considering the partial gap between the shaft 31 and the sleeve 32, gases such as phosphine could enter the turbine assembly 3 through the gap between the shaft 31 and the sleeve 32, and then be transferred to the motor, or even to the vicinity of the circuit board inside the fuselage 1, potentially corroding the copper wire in the motor or the copper layer on the circuit board. To cover the gap, end caps 34 are provided. End caps 34 are mounted on the sleeve 32 and can be screwed, welded, or otherwise fixed. Considering that sleeves 32 are provided at opposite ends of the shaft 31, end caps 34 are installed at opposite ends of the shaft 31.

[0044] The technical solution of the present invention is to install an end cap 34 on the shaft sleeve 32 to prevent gases such as hydrogen sulfide that have the ability to corrode the copper layer from flowing into the interior of the granary robot 100 with the end cap through the gap between the shaft sleeve 32 and the shaft 31, thereby improving the life of the granary robot 100 with the end cap and ensuring that it can operate for a long time in the granary; at the same time, the arc-shaped contour of the end cap 34 reduces the robot's driving resistance, reduces energy consumption, and increases the robot's endurance, and the setting of the end cap 34 can prevent dust from entering the interior 100 of the granary robot with the end cap.

[0045] In one embodiment, see Figure 5 and Figure 8 The turbine 33 includes a sleeve 331, blades and a sleeve 32. The blades are connected to the outer periphery of the sleeve 331. The sleeve 32 is sleeved on the shaft 31. The sleeve 331 is sleeved on the sleeve 32. The shaft 31 is transmission-matched with the sleeve 331 through the sleeve 32. The end cap 34 is installed on the outside of the sleeve 32.

[0046] In one embodiment, see Figure 8The shaft rod 31 is provided with a protruding key bulge 312, and the sleeve 32 is provided with a slot 321 adapted to the key bulge 312. The slot 321 passes through the opposite sides of the sleeve 32. The turbine assembly 3 also includes a fastener 35, which is screwed to the extension section 311 to cover the slot 321.

[0047] In the above embodiment, it is described that the shaft 31 and the sleeve 32 are in transmission cooperation, and the shaft 31 drives the sleeve 32 to rotate synchronously. In this embodiment, it is further described that the shaft 31 and the sleeve 32 are transmitted through the cooperation between the key protrusion 312 and the card slot 321, wherein the card slot 321 passes through the opposite sides of the sleeve 32. In order to prevent the sleeve 32 from moving, a fastener 35 is screwed on the extension section 311 of the shaft 31. This fastener 35 is arranged close to the sleeve 32 toward the end face of the sleeve 32 to cover the card slot 321, thereby further preventing gas from entering the interior of the turbine 33.

[0048] In one embodiment, see Figure 7 and Figure 9 The end cap 34 includes a cap protrusion 341 and a cap brim 342 connected to the outer periphery of the cap protrusion 341 . The cap brim 342 is screwed to the shaft sleeve 32 , and the cap protrusion 341 bulges in a direction away from the shaft sleeve 32 .

[0049] It should be noted that the end cap 34 is circular in shape to facilitate installation and fixation of the end cap 34. The end cap 34 has a cap protrusion 341 and a cap brim 342. The cap brim 342 is screwed onto the sleeve 32, and the cap protrusion 341 bulges away from the sleeve 32 to avoid the extension section 311 of the shaft rod 31 and the fastener 35.

[0050] In one embodiment, see Figure 5 、 Figure 7 as well as Figure 9 A first mounting hole 342a is provided on the brim 342, and a second mounting hole 322 is provided on the sleeve 32 corresponding to the first mounting hole 342a. The brim 342 is screwed onto the sleeve 32 through the first mounting hole 342a and the second mounting hole 322 in sequence.

[0051] Based on the above embodiment, it is understood that screw holes are required on both the brim 342 and the sleeve 32 for screw connection. Therefore, a first mounting hole 342a is provided on the brim 342, and a second mounting hole 322 is provided at a position corresponding to the first mounting hole 342a on the sleeve 32. A screw is sequentially passed through the first mounting hole 342a and the second mounting hole 322 to screw the brim 342 to the sleeve 32, thereby securing the end cap 34.

[0052] In one embodiment, see Figure 7 and Figure 9 The shaft sleeve 32 is provided with a recessed groove 323, the second mounting hole 322 is located in the recessed groove 323, and the inner side of the end cap 34 is provided with a plug post 343 facing the recessed groove 323. The plug post 343 is adapted to the recessed groove 323, and the first mounting hole 342a is provided in the plug post 343.

[0053] It should be noted that in order to facilitate the alignment of the first mounting hole 342a and the second mounting hole 322, so that the brim 342 and the sleeve 32 form a tight fit, a recessed groove 323 is provided on the sleeve 32, wherein the second mounting hole 322 is located in the recessed groove 323, and the end cap 34 is provided with a plug 343 corresponding to the recessed groove 323, so that the plug 343 can be inserted into the recessed groove 323 to form a fit, and the first mounting hole 342a is provided in the plug 343, and then when the plug 343 is matched with the recessed groove 323, the first mounting hole 342a and the second mounting hole 322 are aligned, thereby ensuring a good fit between the brim 342 and the sleeve 32, thereby improving the sealing effect of the end cap 34.

[0054] It is understood that the number of the first mounting holes 342a and the second mounting holes 322 can be two, three, or more. In this embodiment, the number of the first mounting holes 342a and the second mounting holes 322 are respectively two. The two first mounting holes 342a are spaced apart in the circumferential direction of the brim 342, so the two second mounting holes 322 are also spaced apart in the circumferential direction of the sleeve 32. Furthermore, the number of the plug posts 343 and the countersunk grooves 323 corresponds to the number of the first mounting holes 342a and the second mounting holes 322. In this embodiment, the number of the plug posts 343 and the countersunk grooves 323 are both two.

[0055] In one embodiment, see Figure 10 The turbine 33 includes a sleeve 331 and a spiral blade 332 connected to the sleeve 331. The sleeve 32 includes an insertion section 324 and a limiting section 325. The limiting section 325 is connected to the insertion section 324. The insertion section 324 extends into the sleeve 331. The limiting section 325 contacts the outer end surface of the sleeve 331. A protrusion 324a is provided on the outer periphery of the insertion section 324. The protrusion 324a corresponds to the first mounting hole 342a. A positioning groove 331a is provided inside the sleeve 331 corresponding to the protrusion 324a. The protrusion 324a and the positioning groove 331a match each other.

[0056] Specifically, in the above embodiment, it has been described that the turbine 33 is hollow. More specifically, the turbine 33 includes a sleeve 331 and a spiral blade 332 connected to the sleeve 331. The sleeve 331 is a cylindrical hollow cylinder. The spiral blade 332 is spirally wound on the sleeve 331. The number of spiral blades 332 can be one, two, or more. Considering the stirring effect of the turbine 33 on the grain, in this embodiment, two spiral blades 332 are connected to the outer shaft of the sleeve 331. The spiral blade 332 and the sleeve 331 can be integrally formed or connected by welding, which is not specifically limited here.

[0057] Furthermore, the shaft sleeve 32 includes an insertion section 324 that extends into the sleeve 331 and a limiting section 325 that abuts the outer end surface of the sleeve 331. The limiting section 325 has a larger diameter than the insertion section 324. Thus, the limiting section 325 can limit the relative position of the shaft sleeve 32. To ensure greater strength in the threaded connection between the end cap 34 and the shaft sleeve 32, a protrusion 324a is provided on the outer periphery of the insertion section 324, thereby enhancing the structural strength of the peripheral wall of the first mounting hole 342a. Furthermore, a positioning groove 331a is provided on the sleeve 331 corresponding to the protrusion 324a. The protrusion 324a mates with the positioning groove 331a, thereby preventing the shaft sleeve 32 from rotating relative to the inner wall of the sleeve 331.

[0058] In one embodiment, see Figure 5 and Figure 7 The outer periphery of the extending section 324 is interference fit with the inner wall of the sleeve 331 .

[0059] Furthermore, it should be noted that the end cap 34 does not cover the gap between the shaft sleeve 32 and the turbine 33. In order to ensure the sealing effect of the turbine assembly 3, the outer periphery of the extension section 324 is interference fit with the inner wall of the sleeve 331. On the one hand, it can prevent the extension section 324 from rotating relative to the inner wall of the sleeve 331. On the other hand, the outer periphery of the extension section 324 and the sleeve 331 are interference fit, which can seal the gap between the shaft sleeve 32 and the turbine 33, thereby preventing external miasma from entering the fuselage 1.

[0060] In one embodiment, please continue to refer to Figure 5 and Figure 7 The outer wall surface of the cap protrusion 341 is arranged in an arc shape.

[0061] It should be noted that, considering that the granary robot 100 with end caps will continue to move forward while turning the grain in the granary, in order to reduce the resistance encountered by the granary robot 100 with end caps during the forward movement, the outer wall surface of the cap protrusion 341 is set to an arc surface, which can reduce the contact between the cap protrusion 341 and the grain, so that the granary robot 100 with end caps can move forward more smoothly in the granary.

[0062] In one embodiment, the end cap 34 is made of either aluminum alloy or PPS. Considering that the grain silo robot 100 with end caps will continuously advance while turning grain within the silo, the end cap 34 will be constantly impacted by the grain ahead. Grains such as soybeans and soya beans have strong impact forces, so the end cap 34 must be able to withstand a certain degree of impact without deformation. Therefore, the end cap 34 can be made of either aluminum alloy or PPS.

[0063] 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.
