DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Example 1

[0028] In one embodiment of the present invention, referring to Figure 1 As shown, it includes a grab bucket for grabbing wine lees, which includes two bucket lobes 11 around a first rotating shaft 22; the two bucket lobes 11 are driven to open and close around the first rotating shaft 22 to achieve grabbing and releasing the wine lees; the first rotating shaft 22 is set on the bracket 17, and when working, the bracket 17 is connected to the robot arm and is driven to move by the robot arm; the openings of the two bucket lobes 11 are flat, and the two bucket lobes 11 can be closed tightly.

[0029] In one embodiment of the present invention, referring to Figure 1As shown, it includes a scraping device, which is connected to the second rotating shaft 21, and the second rotating shaft 21 is set on the bracket 17; the scraping device is used to scrape the lees after the grab bucket unloads the lees and is in an open state, and the scraping device is moved by the grab bucket; the scraping device is set on the bucket petal 11, and the scraping device includes a scraping rod 2 set around the grab bucket, and a rotating assembly 19 that drives the scraping rod 2 to rotate around the second rotating shaft 21. The scraping rod 2 is initially at the top of the lifting and lowering bucket, and when in use, it is driven by the rotating assembly 19 to rotate to the opening of the grab bucket.

[0030] The rotation radius of the scraping rod 2 is greater than the maximum rotation radius of the bucket 11, so that the scraping rod 2 does not contact the bucket 11 during rotation; the scraping rod 2 is provided with a plurality of parallel scraping needles 10 at intervals, and the scraping needles 10 are perpendicular to the plane where the scraping rod 2 is located. The rod is used to insert into the wine lees with the help of the movement of the grab after the grab is fully opened, and move on the surface of the wine lees to scrape the wine lees flat. There is a gap between the scraping needles 10, and the scraping needles 10 are set as a thin rod structure. Part of the wine lees can pass through the gap, which is beneficial to reduce the friction between the grab and the wine lees and improve the stability of the device.

[0031] In one embodiment of the present invention, referring to Figure 1 As shown, it includes two scraping devices, which are mirror-imaged on the two bucket lobes 11 and rotate in opposite directions. When in use, each of them rotates to the opening of the corresponding bucket lobes 11; the structures are independent and cooperate with each other.

[0032] In one embodiment of the present invention, referring to Figure 3 As shown, the scraper rod 2 includes a cross beam 16 and two parallel support rods 2 connecting the two ends of the cross beam 16. To be precise, the ends of the support rods 2 are connected to the ends of the cross beam 16; the length of the support rod 2 is greater than the longest length of the bucket lobe 11 to ensure that the cross beam 16 does not contact the bucket lobe 11, and the support rod 2 is arranged parallel to the side of the bucket lobe 11; to be precise, the rotating assembly 19 is arranged at the other end of the support rod 2 and is located between the two support rods 2, so that the scraper rod 2 is connected to the second rotating shaft 21 through the rotating assembly 19.

[0033] In one embodiment of the present invention, referring to Figure 3 As shown, the support rod 2 is arranged perpendicular to the cross beam 16, so that the area enclosed by the support rod 2 and the cross beam 16 is square, and the width between the two support rods 2 is greater than the width of the bucket 11, so that the square can accommodate the bucket 11. The square area prevents the bucket 11 from contacting the rotating scraper rod 2. If contact occurs, the scraper device will be damaged.

[0034] In one embodiment of the present invention, referring to Figure 3 As shown, thirteen connecting seats 9 are arranged at intervals in the extension direction of the crossbeam 16, and the specific number can be expanded according to actual use. The connecting seat 9 is provided with a groove, and screw holes are provided on both sides of the groove to connect the scraper needle 10; the purpose of the interval setting is to flexibly adjust the spacing of the scraper needle 10 and adjust the scraping effect.

[0035] In one embodiment of the present invention, referring to Figure 3 As shown, the scraping needle 10 is provided with a connecting head 15 and a tip 13 connected to the connecting head 15, and the connecting head 15 is provided with a through hole; the connecting head 15 is connected to the connecting seat 9, the connecting head 15 is profiled to match the groove, and the screw hole of the connecting seat 9 is aligned with the through hole of the connecting head 15, and is fixed with a screw 1; the tip 13 is in contact with the lees, and the tip 13 is set to a structure that gradually becomes smaller toward the free end. Different parts of the scraping needle 10 are aimed at lees with different flatness, which is conducive to better scraping the lees.

[0036] In one embodiment of the present invention, referring to Figure 3 As shown, it includes two first rotating components 19 and second rotating components 19 arranged opposite to each other, both of which are provided with a common driver and other structures for connection. The output end of the driver is fixedly connected to the scraper rod 2, and the first rotating component 19 and the second rotating component 19 work synchronously; the first rotating component 19 and the second rotating component 19 not only play the role of driving the scraper rod 2 to rotate, but also play the role of bearing the load of the scraper rod 2.

[0037] In one embodiment of the present invention, referring to Figure 2 As shown, a through hole 20 is provided on each side of the bucket 11, and the first rotating component 19 and the second rotating component 19 pass through the through holes 20 respectively to connect to the second rotating shaft 21. It should be noted that the rotating component 19 is not directly connected to the bucket 11. The purpose is to ensure that the bucket 11 and the scraper component rotate independently without interfering with each other.

[0038] In one embodiment of the present invention, referring to Figure 2 As shown, the first rotating shaft 20, the second rotating shaft 21 and the through hole 20 are coaxially arranged, the purpose of which is to make the bucket 11 and the corresponding scraper device have the same rotation center. When the length of the support rod 2 is determined, the crossbeam 16 will not interfere with the bucket 11.

[0039] In one embodiment of the present invention, referring to Figure 2As shown, the scraping needle 10 extends toward the opening of the bucket lobe 11. Specifically, the scraping needle 10 is arranged on one side of the crossbeam 16, which is on the same side as the opening of the bucket lobe 11 after the scraping rod rotates to the opening of the bucket lobe 11, and the scraping needle 10 exceeds the opening of the bucket lobe 11 by a certain length. The purpose is that after the scraping rod rotates into place, the scraping needle 10 can be inserted into the lees, and there is space to adjust the insertion depth.

[0040] In one embodiment of the present invention, referring to Figure 4 As shown, the rotating component 19 includes a motor 6 and a fastening seat 13 arranged at the output end of the motor 6. The fastening seat 13 is connected to the support rod 2. The purpose of setting the fastening seat 13 is to more firmly connect the drive and the support rod 2, and to bear part of the load from the support rod 2 to protect the motor 6.

[0041] In one embodiment of the present invention, referring to Figure 4 As shown, the fastening seat 13 includes an inner shaft 8 connected to the scraper rod 2, the inner shaft 8 is connected to the output end of the motor 6, and the inner shaft 8 rotates synchronously with the output end; one end of the inner shaft 8 is fixedly connected to the support rod 2 by a screw 1.

[0042] In one embodiment of the present invention, referring to Figure 4 As shown, the fastening seat 13 also includes a first bearing 4 connected to the motor 6. The bearing sleeve is arranged on the output end of the motor 6, and the first bearing 4 is nested therein to reduce the friction between the output end of the motor 6 and the inner shaft 8. In addition, the fastening seat 13 also includes common connection structures such as a screw 1, a second bearing 7, an outer shaft 3, and a flange 5, which will not be repeated here.

[0043] The working principle of the grab bucket of the present invention is:

[0044] When the grab grabs the lees, the scraping rod 2 is set above the bucket 11 to avoid the action of grabbing and releasing the lees, thereby preventing damage to the device; when the grab is fully unfolded to release the lees, the opening of the bucket 11 faces the lees, and the rotating component 19 drives the two scraping rods 2 to rotate to the openings of their respective bucket lobes 11, and the support rod 2 is parallel to the edge of the bucket lobes 11 opening, and the tip 13 of the scraping needle 10 is facing the lees. The scraping needle 10 uses the movement of the grab to insert into the lees and moves back and forth on the surface of the lees to scrape the lees. Multiple scraping needles 10 are set at intervals, and the lees can be filtered out through the gaps, reducing the friction between the grab and the lees and improving the stability of the device. After the scraping is completed, the scraping rod 2 rotates to the top of the bucket lobes 11, thereby improving work efficiency.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
