[0025] 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 are within the scope of protection of the present invention.

[0026] Refer to Figure 1-Figure 2 The scraping and compacting mechanism for a wine cellar shown in the figure comprises a scraping assembly 1 and a compacting assembly 2 which is arranged on the inner side of the scraping assembly 1 and can be lifted. That is, the scraping assembly 1 and the compacting assembly 2 are arranged in an integrated manner, and the scraping and compacting work can be achieved by positioning them once. The scraping assembly 1 comprises a frame-shaped pushing bracket 11, guide rails 13 arranged on the inner sides of the two symmetrical ends of the pushing bracket 11, guide blocks 14 mounted on the guide rails 13, a travel motor 15 for driving the corresponding guide blocks 14 to move back and forth on the guide rails 13, and a motor connected between the two guide blocks 14. The scraper member 16 is located between the pusher bracket 11 and below the pusher bracket 11. The two walking motors 15 are operated synchronously to realize the reciprocating work of the scraper member 16 on the guide rail 13. The top of the pusher bracket 11 is fixedly connected to a support seat 17 supporting the compaction component 2 to ensure the stability of the up and down movement of the compaction component 2. A driving rotating member 18 for driving the compaction component 2 to rotate and a lifting cylinder 19 for driving the compaction component 2 to lift are respectively installed on the top surface of the support seat 17. The lifting cylinder 19 is mainly used for the compaction work of the compaction component 2;

[0027] The compacting assembly 2 includes a pressure plate member 21 arranged on the inner side of the frame of the pushing bracket 11, a T-shaped lifting rod 22 connected to the top surface of the pressure plate member 21 and coaxially arranged on the inner side of the support seat 17, a connecting sleeve 23 fixed on the top of the T-shaped lifting rod 22 and a telescopic connecting rod 24 for driving the pressure plate member 21 to expand. The pressure plate member 21 follows the T-shaped lifting rod 22 to rise to the top of the pushing bracket 11 and shrinks, and then expands when it descends to the bottom of the pushing bracket 11. The transverse cross-sectional range of the pressure plate member 21 after expansion is larger than the transverse cross-sectional range of the pushing bracket 11, so as to ensure that the wine vat can be covered as much as possible during compaction, or the pile material within the scraping range can be compacted evenly.

[0028] Reference Figure 1-Figure 3 The two symmetrical end sides of the pusher bracket 11 are penetrated by a through groove 12, and the guide rails 13 are installed on the upper and lower side walls of the through groove 12. The upper and lower ends of the guide block 14 are fitted into the guide rails 13 to ensure the stability of the guide block 14 when sliding on the guide rails 13.

[0029] Reference Figure 3-Figure 4 The scraper member 16 includes a side connecting plate 163 fixed to the side of the slider, an angle adjustment motor 164 installed in the middle of the side connecting plate 163, a lifting link 162 fixedly connected to the output shaft of the angle adjustment motor 164, and a push plate 161 located below the pushing bracket 11. The side connecting plate 163 and the guide block 14 are detachably connected by bolts, and the length or size of the push plate 161 can be adjusted as needed. The push plate 161 is T-shaped, and the lower end of the T-shape is downward in contact with the pile. The bottom ends of the two lifting links 162 are vertically fixed to the two ends of the T-shaped upper part of the push plate 161. The two angle adjustment motors 164 drive the lifting link 162 to rotate and drive the push plate 161 to tilt and resist the inside of the wine cellar wine tank, and the two side ends of the guide block 14 are provided with contact When the guide block 14 moves to the end of the guide rail 13, the contact sensor contacts the pusher bracket 11, thereby transmitting signals to the travel motor 15 and the angle adjustment motor 164. Initially, the angle adjustment motor 164 drives the push plate 161 to rotate and contact the wall of the wine tank, so that the inclined push plate 161 is leveled. When it moves to the other end, the space between the push plate 161 and the inner wall of the wine tank at the other end can be made larger to accommodate more piles of materials, ensuring the stability of the push plate 161 during long-term work. When returning, the inclined push plate 161 adjusts the tilting direction under the operation of the lifting link 162 and the angle adjustment motor 164 to facilitate the next set of leveling work. At the same time, a bottom groove for the rotation of the lifting link 162 is opened at the bottom of the inner bottom of the pusher bracket 11.

[0030] Reference Figure 1-Figure 3 and Figure 5The support seat 17 includes an L-shaped support rod 171 and a hollow circular plate 172. Four L-shaped support rods 171 are arranged in a circular array. One end of the L-shaped support rod 171 is vertically fixed at the corner of the top surface of the pushing bracket 11, and the other end is vertically fixed on the outer wall of the circumference of the hollow circular plate 172. When the L-shaped support rod 171 is located at the corner of the pushing bracket 11, the retracted pressure plate 21 will not be interfered with by the L-shaped support rod 171. At this time, the hollow circular plate 172 is located directly above the center of the pushing bracket 11.

[0031] Reference Figure 2-Figure 3 and Figure 6-Figure 7 The pressure plate member 21 includes a square main pressure plate 211 and side pressure plates 212 hinged on the four sides of the top surface of the main pressure plate 211. The side pressure plates 212 are isosceles triangles. When the four side pressure plates 212 are unfolded, they form a square structure with the main pressure plate 211 to adapt to the shape of the wine vat. Similarly, if the wine vat is circular, the side pressure plates 212 are arc-shaped to form a circular structure with the main pressure plate 211, and the bottom surfaces of the main pressure plate 211 and the side pressure plates 212 are provided with a number of trapezoidal teeth to facilitate compaction work.

[0032] The T-shaped lifting rod 22 includes a prismatic rod 222 at the upper end and a round rod 221 at the lower end. The bottom end of the round rod 221 is fixed to the center of the top surface of the main pressure plate 211, and the prismatic rod 222 slides through the center of the hollow circular plate 172 to ensure that the T-shaped lifting rod 22 can be lifted and lowered on the support seat 17 and can also rotate at the same time.

[0033] Reference Figure 6-Figure 8 The connecting block 23 is disc-shaped and fixedly sleeved on the upper end of the round rod 221. The top surface of the connecting block 23 is annularly arrayed with hinge grooves 231 for the installation of the telescopic link 24, so that the two ends of the telescopic link 24 are respectively hinged to the connecting block 23 and the side pressure plate 212. The telescopic link 24 and the lifting link 162 are both electric push rods. Two arc-shaped limit slots 232 are symmetrically provided on the top surface of the connecting block 23. The bottom end of the lifting cylinder 19 is connected to a slider that fits in the arc-shaped limit slot 232. When the connecting block 23 rotates, the bottom of the lifting cylinder 19 can rotate in the connecting block 23, and at the same time, the lifting cylinder 19 can still drive the connecting block 23 to move up and down, thereby driving the entire compacting assembly 2 to move up and down.

[0034] Reference Figure 3 、 Figure 5 and Figure 9The driving rotating member 18 includes a rotating motor 181 mounted on the top surface of the hollow circular plate 172, a driving gear 183 connected to the output shaft of the rotating motor 181, and a driven gear disc 182 sleeved on the outside of the prismatic rod 222. The driven gear disc 182 is slidably connected to the prismatic rod 222 to achieve the rotation of the driven gear disc 182 by the prismatic rod 222. A pressure sensing block 184 is fixed on the top surface of the driven gear disc 182. The inner top wall of the hollow circular plate 172 is provided with two concave holes 185 adapted to the pressure sensing block 184 in an annular array. The two concave holes 185 are 45 degrees apart, so that the driven gear disc 182 can rotate smoothly. 2 is driven to rotate, at this time, the pressure sensing block 184 slides out of the concave hole 185. At this time, the pressure sensing block 184 is squeezed by the top wall of the hollow circular plate 172 under the action of elasticity, thereby sensing the external force. At this time, it can be determined that the compacting assembly 2 is in a rotating state as a whole, and the lifting cylinder 19 can drive the compacting assembly 2 to be in a rapid up and down shaking state to shake off the adhered pile materials as much as possible. After rotating 45 degrees, the pressure sensing block 184 enters another concave hole 185, and then it is determined that the 45-degree rotation is completed. The lifting cylinder 19 is no longer in the rapid shaking state and normal subsequent work begins.

[0035] Specifically, the scraping and compacting mechanism for the wine cellar, when scraping and leveling the pile of materials, first moves the pushing bracket 11 to the top of the wine tank by the hanger mechanism of the wine cellar, and after positioning is completed, slowly moves downward to enter the wine tank until the push plate 161 enters the wine tank to the pile of materials scraping and leveling position, at this time, the walking motor 15 is started, and the walking motor 15 drives the guide block 14 to move back and forth on the guide rail 13, and drives the push plate 161 to move from one end of the wine tank to the other end, and in the process of moving, the push plate 161 always keeps tilted until it moves to the end of the other end, at this time, the lifting link 162 drives the push plate 161 to rise first, and then the angle adjustment motor 164 drives the push plate 161 to rotate, after changing the tilt angle of the push plate 161, the lifting link 162 drives the push plate 161 downward again, and after changing the tilt direction of the push plate 161, starts the next set of scraping and moving work;

[0036] After the scraping is completed, when the material is compacted, the push plate 161 is first moved to the edge of the push bracket 11, and then the lifting cylinder 19 is started to extend, driving the pressing plate 21 to move downward until the pressing plate 21 moves to the bottom of the push bracket 11, that is, Figure 1 Move to Figure 2Position, then the lifting cylinder 19 stops working, the rotating motor 181 starts, and driven by the driving gear 183 and the driven gear plate 182, the T-shaped lifting rod 22 and the pressure plate 21 rotate 45°. After the rotation is completed, the telescopic connecting rod 24 begins to extend and drives the four side pressure plates 212 to expand until the side pressure plates 212 are flush with the main pressure plate 211, forming a square structural plate again. Finally, the lifting cylinder 19 works again to drive the direction structural plate to compact the pile of materials in the wine tank. After the compaction is completed, the telescopic connecting rod 24 contracts first to restore the side pressure plates 212 to a vertical state with the main pressure plate 211. The rotating motor 181 works in the opposite direction, driving the T-shaped lifting rod 22 and the pressure plate 21 to rotate 45° in the opposite direction to restore the initial state. Finally, the lifting cylinder 19 contracts, driving the pressure plate 21 to move upward to above the pushing bracket 11.
