For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] The following will be described in detail Figures 1 to 5The utility model discloses a novel fermentation vat weld polishing machine, including frame body 10, fermentation vat positioning frame 20, first polishing part 30 and second polishing part 40, fermentation vat positioning frame 20 sets up at the tail end of frame body 10, and first polishing part 30 sets up at one side of fermentation vat positioning frame 20, and fermentation vat positioning frame 20 includes driving roller 21, passive roller 22 and pressure roller 23, three enclose fermentation vat, and drive fermentation vat to roll, and second polishing part 40 includes control frame 41 and second polishing machine 42, and control frame 41 has extension rod 43, and second polishing machine 42 sets up at the end of extension rod 43 to extend into the inside of fermentation vat.

[0034] As shown in the drawings, Figure 1 and Figure 2 The frame body 10 is a square operation table structure, supported by support legs at the bottom and provided with an operation platform at the top to set various polishing and positioning adjustment structures.

[0035] Further, as shown in the drawings, Figure 3 The first polishing part 30 includes a translation mechanism 31 and a first polishing machine 32, and the first polishing machine 32 is arranged at the top of the translation mechanism 31. A first adjustment hand wheel 33 is arranged at the tail end of the translation mechanism 31 to control the first polishing machine 32 to approach or move away from the fermentation vat. The first polishing machine 32 can adopt a longitudinal grinding wheel structure as shown in the drawings, which can be arranged at the welding position of the cylindrical barrel body and the conical bottom of the fermentation vat to polish the weld.

[0036] To polish the weld more accurately and to finely control the first polishing machine 32, as shown in the drawings, Figure 3 The translation mechanism 31 can include a base 311 and a translation plate 312. The translation plate 312 is connected to the first adjustment hand wheel 33 through a threaded column, and the base 311 is provided with a mounting groove. The side wall of the translation plate 312 is slidably connected to the inner wall of the mounting groove.

[0037] It can be understood that the base 311 is a base structure for carrying the entire first polishing machine 32 and the translation plate 312. A mounting hole is formed in the front of the base to allow the threaded column of the first adjustment hand wheel 33 to pass through the base 311 and be connected to the side wall of the translation plate 312. In this way, through threaded cooperation, when the first adjustment hand wheel 33 is rotated, the translation plate 312 is driven to move longitudinally, and the first polishing machine 32 is made to approach or move away from the weld.

[0038] Further, the first motor 34 is arranged at the top of the translation plate 312 and connected to the first polishing machine 32, so that Figure 3As can be seen, the first motor 34 is connected with the first polishing machine 32 through a belt, and the reliability is improved through overload protection of the belt connection, and the belt connection can be adapted to different transmission ratios and application scenarios by replacing different types of belts (such as triangular belts, synchronous belts, etc.), and is more flexible to use.

[0039] Preferably, as Figure 3 shown, the bottom of the frame body 10 is provided with a driving motor 11, the driving motor 11 is connected with a driving drum 21, the driving drum 21 and the driven drum 22 are located in the same plane and have a certain interval, the pressing drum 23 is located above the interval center between the driving drum 21 and the driven drum 22, and has two rollers to make the rolling of the fermentation barrel more smooth.

[0040] Wherein, the top of the frame body 10 is provided with a hanger 12, the hanger 12 is protruded to the fermentation barrel at the end, and a pressing cylinder 13 is arranged at the end, and the pressing cylinder 13 is connected with the pressing drum 23. It can be understood that the driving drum 21, the driven drum 22 and the pressing drum 23 form a structure similar to a triangular enclosure to enclose the fermentation barrel, which not only has stronger stability, but also through the setting of the drum structure, the drum structure cooperates with the cylindrical fermentation barrel body, and under the driving of the driving motor 11, the fermentation barrel is rolled, and then the overall polishing of the weld is realized.

[0041] In addition, as Figure 2 shown, the hanger 12 can be arranged on the side opposite to the second polishing machine 42, so as to more effectively utilize the space on the surface of the frame body 10; and by extending the pressing cylinder 13 at the hanger 12 to drive the pressing drum 23 to adjust in the vertical direction, the positioning effect of the fermentation barrel can be improved.

[0043] It can be understood that, due to the setting of the driving motor 11, the longitudinal position of the driving drum 21 is difficult to adjust, so the avoiding space 27 can be arranged at the position area of the driving motor 11 on the frame body 10, so that the second adjusting hand wheel 26 can directly drive the driving motor 11 and the driving drum 21 to move longitudinally at the same time, thereby improving the convenience of adjustment.

[0049] It can be understood that the vertical hand wheel 46 can not only be arranged for the lifting of the extension rod 43, but also can adjust the height position of the extension rod 43; in addition, the longitudinal adjusting plate 45 is arranged, so that the longitudinal hand wheel 47 drives it to be finely adjusted longitudinally, so that the adjustment is more accurate; specifically, the back side of the longitudinal adjusting plate 45, that is, the side of the frame body 10 where the crane is arranged, can be provided with a threaded hole structure protruding to the top, so as to facilitate cooperation with the screw rod structure of the longitudinal hand wheel 47, and drive the entire longitudinal adjusting plate 45 to move through threaded cooperation; in addition, the sliding groove of the top wall of the adjusting frame 41 can not only provide a mounting space for the vertical hand wheel 46, but also can ensure that the vertical hand wheel 46 has sufficient longitudinal movement space, so that the longitudinal adjusting plate 45 can drive the upper vertical hand wheel 46 and the lower extension rod 43 to move synchronously.

[0050] Optionally, in order to improve the supporting effect of the extension rod 43, the four supporting columns 44 of the adjusting frame 41 can be provided with a positioning frame 48 sliding up and down, the positioning frame 48 is slidingly connected to the supporting column 44, and the supporting rod is connected to the top and bottom of the extension rod 43, which plays a role in adjusting and supporting; in addition, in order to ensure the longitudinal adjustment of the extension rod 43, a circular hole-shaped sliding hole can be arranged on the side wall of the positioning frame 48, and the supporting rod can pass through the sliding hole to support and ensure the longitudinal adjustment; of course, these structures should be provided with a locking member to position the position after adjustment; the structure of the locking member can adopt a common plug rod structure or a threaded locking structure.
