[0041] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0042] like Figure 1-6 As shown, this utility model provides a portable grain storage robot, including: a chassis 110, a spiral wheel 120, a drive device 130, a connecting frame 140, a pull rod 150, a towing wheel bracket 160, and a towing wheel 170.

[0043] Two sets of spiral wheels 120 are respectively arranged on both sides below the chassis 110. Two drive devices 130 are arranged one-to-one with the two sets of spiral wheels 120 to drive the spiral wheels 120 to rotate.

[0044] In this embodiment, each set of spiral wheels 120 includes a first spiral wheel 121 and a second spiral wheel 122; the first spiral wheel 121 and the second spiral wheel 122 are coaxially spaced apart. A drive device 130 is located between the first spiral wheel 121 and the second spiral wheel 122 in the same set. Both ends of the output shaft of the drive device 130 extend outside the drive device 130 and are coaxially connected to one end of the spindle of the first spiral wheel 121 and one end of the spindle of the second spiral wheel 122, respectively. The output shaft of the drive device 130 is arranged along the length direction of the chassis 110.

[0045] As a preferred embodiment, the portable grain storage robot further includes two helical wheel mounting brackets 180, respectively positioned near both ends of the chassis 110. The other ends of the spindles of the two first helical wheels 121 (near the traction wheel 170) and the other ends of the spindles of the two second helical wheels 122 are rotatably supported on the two helical wheel mounting brackets 180. By using the helical wheel mounting brackets 180, the problem of wheel axle misalignment during long-term operation of the grain-turning robot can be avoided.

[0046] As a further preferred embodiment, the side of the spiral wheel fixing frame 180 facing away from the chassis is an outwardly protruding arc-shaped plate, the axis of which is arranged along the width direction of the chassis 110. By setting the arc-shaped plate, the grain resistance encountered by the grain-turning robot can be reduced, and damage to the grain can be avoided when the spiral wheel fixing frame 180 comes into contact with the grain.

[0047] Two connecting brackets 140 are symmetrically and detachably installed on both sides of the chassis 110; the connecting brackets 110 are arranged along the length of the chassis 110, and the two ends of the connecting brackets 140 are respectively facing the two ends of the chassis 110.

[0048] The pull rod 150 includes a first crossbeam 151 and two first connecting rods 152. One end of each of the two first connecting rods 152 is symmetrically fixed to both ends of the first crossbeam 151, and the first connecting rods 152 are perpendicular to the first crossbeam 151. The other ends of the two first connecting rods 152 are connected to one end of each of the two connecting frames 140, and the first connecting rods 152 can move axially along one end of the connecting frame 140, that is, the first connecting rods 152 and the connecting frame 140 form a telescopic pull rod structure, allowing the first crossbeam 151 to move closer to or further away from the chassis 110. The structure of the telescopic pull rod is not specifically limited. In one embodiment, the telescopic pull rod structure is the same as the telescopic pull rod structure of a luggage case.

[0049] The tow wheel bracket 160 includes a second crossbeam 161 and two second connecting rods 162; one end of each of the two second connecting rods 162 is symmetrically fixed to both ends of the second crossbeam 161, and the second connecting rods 162 are perpendicular to the first crossbeam 161. Two sets of tow wheels 170 are respectively installed on the outside of the two second connecting rods 162 and are positioned close to the crossbeam 161.

[0050] The other ends of the two second links 162 are connected to the other ends of the two connecting frames 140 respectively. The second links 162 can rotate relative to the connecting frames 140, so that the towing wheel 170 is flipped over above the chassis 110.

[0051] In this embodiment, the second connecting rod 162 is connected to the connecting frame 140 via a first pin 141 and a second pin 142 spaced apart along the axial direction. When the towing wheel frame 160 needs to be flipped, the second pin 142 farther from the towing wheel 170 is pulled out, causing the towing wheel frame 160 to rotate around the unpulled first pin 141, thus achieving the flipping. Simultaneously, a rotatable limiting connecting rod 143 is installed on the connecting frame 140. One end of the limiting connecting rod 143 is semi-open, and a limiting post 162a is provided on the outer side of the second connecting rod 162. When the towing wheel 170 rotates above the sealing cover 190, the limiting connecting rod 142 is rotated, locking the opening of the limiting connecting rod 142 onto the limiting post 162a, thereby fixing the towing wheel 170 (e.g., ...). Figure 6 (As shown), to prevent the position of the tow wheel 170 from moving when the grain turning robot is working. When carrying upstairs, the opening of the limit link 142 can be locked onto the second pin 142 to prevent the limit link 142 from shaking.

[0052] The tow wheel 170 includes: a mounting bracket 171, a central shaft 172, and a caster 173.

[0053] Two mounting brackets 171 are symmetrically and parallelly spaced apart; each mounting bracket 171 is an equilateral triangle. A central shaft 172 passes through and connects the center of the two mounting brackets 171. One end of the central shaft 172 is rotatably connected to a second connecting rod 162, allowing the two mounting brackets 171 to rotate relative to the towing wheel bracket 160.

[0054] Three casters 173 are all located between two mounting brackets 171, and each caster 173 is positioned at one of the top corners of the mounting brackets 171. The casters 173 are rotatably connected to the two mounting brackets 171 via a pivot. The three-caster configuration makes it easier to climb stairs.

[0055] The cavity above the chassis 110 is provided with a battery mounting slot 111 and an electrical control box mounting slot 112, which are used to install the battery and the electrical control box (control box), respectively.

[0056] In this embodiment, a sealing cover 190 is provided above the chassis 110. The battery and the electrical control box are both located inside the sealing cover 190. The sealing cover 190 serves to seal and prevent dust, while also protecting the internal components of the chassis 110 (such as the battery and electrical control box).

[0057] As a preferred embodiment, the outer top edge of the chassis 110 is provided with a first convex ridge array 113, and the inner edge of the sealing cover 190 is provided with a second convex ridge array that matches and engages with the first convex ridge array 113. The chassis 110 and the sealing cover 190 achieve dust prevention through the cooperation of the first convex ridge array 113 and the second convex ridge array. The sealing cover 190 is divided into front and rear parts. During installation, the front and rear parts of the sealing cover slide from both ends to the middle position along the first convex ridge array 113 to achieve docking.

[0058] As a preferred embodiment, the bottom of the chassis 110 is provided with a groove, and heat dissipation fins 114 are embedded in the groove. By setting the heat dissipation fins 114, the heat dissipation effect of the grain turning robot can be improved.

[0059] As a preferred embodiment, the chassis 110 has a truncated pyramidal structure that is wider at the top and narrower at the bottom. The inclination angles of the front face 115 and the rear face 116 of the chassis 110 are the same as or close to the gravity flow angle of the grain. This is to prevent the grain-turning robot from plunging downwards into the grain pile during its movement.

[0060] When the grain-turning robot needs to be moved upstairs, the pull rod 150 can be pulled out of the connecting frame 140 to its maximum length, the towing wheel bracket 160 can be flipped to be flush with the pull rod 150, and the grain-turning robot can be inverted so that the sealing cover 190 faces downwards (as shown in the image). Figure 7 (As shown); to avoid bumping into the spiral wheel 120 during movement. In addition, the design of the lever and the towing wheel makes it easier for the grain turning robot to be flipped (inverted), which facilitates the maintenance and upkeep of the grain turning robot.

[0061] When the grain-turning robot is performing grain-turning work, the tractor 170 is flipped over to be above the chassis 110 (sealed cover 190), and the lever 150 is retracted to its shortest position (as shown in the image). Figure 8 As shown in the figure, this ensures that the tow wheel 170 and the lever 150 do not interfere with the operation of the grain turning robot.

[0062] In another embodiment, the towing frame 160 can also be configured as a telescopic structure with the same structure as the pull rod 150. When the grain turning robot is working, the towing frame 160 can be retracted to one end near the tray 110 (as shown in the image). Figure 9 (As shown).

[0063] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
