Description

Technical Field

[0001] The present invention relates to a material-taking bucket applicable to fermented materials in a ground tank, and belongs to the technical field of material-taking for brewing ground tanks. Background Art

[0002] The brewing ground tank generally has a special structure with a large mouth and a small bottom. It is difficult for an ordinary bucket to meet the requirements of taking more materials and leaving less leftovers. Moreover, the fermented materials involved have a large viscosity and are easy to stick to the bucket. During the process of taking materials and transferring materials by the bucket, material scattering is likely to occur, resulting in material waste and increasing the cleaning work. Summary of the Invention

[0003] The present invention overcomes the deficiencies of the prior art and provides a material-taking bucket applicable to fermented materials in a ground tank, solving the above problems.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A material-taking bucket applicable to fermented materials in a ground tank includes a robot end connecting plate, a bucket electric cylinder, a herringbone connecting rod, a bucket main shaft, a bucket connecting shaft, and a bucket. The cylinder body of the bucket electric cylinder is fixed on the lower side of the robot end connecting plate. The upper side of the robot end connecting plate is connected to the robot execution end to achieve multi-degree-of-freedom motions including rotation and movement. The execution end of the bucket electric cylinder is connected to the upper end of at least one herringbone connecting rod through a lifting cross bar. The lower ends of the herringbone connecting rods are all connected with bucket connecting shafts. Both ends of the bucket main shaft are connected to the rotation centers of two symmetrically arranged buckets. Both ends of the two bucket connecting shafts are respectively connected to the lifting sections of the two buckets, so that the two buckets are driven by the bucket electric cylinder to open and close. A support rod is vertically arranged on the robot end connecting plate. The lower end of the support rod is sleeved on the bucket main shaft. The bucket is a polyhedron structure. A scraping plate mechanism is arranged on the support rod. The execution end of the scraping plate mechanism is arranged to closely adhere to the inner wall of the bucket, realizing the scraping function during the opening and closing process of the bucket;

[0005] A scraping cylinder air cylinder is arranged on the support rod. The cylinder body of the scraping cylinder air cylinder is fixedly arranged on the support rod. The execution rod of the scraping cylinder air cylinder is movably connected to a reversing cross shaft through a connecting rod. The reversing cross shaft is driven by the scraping cylinder air cylinder to reciprocate horizontally. A scraping cylinder plate is vertically movably arranged at the outer end of the reversing cross shaft. The outer end contour of the scraping cylinder plate is arranged to match the shape of the inner wall of the ground tank. The scraping cylinder plate is pressed against the inner wall of the ground tank through the horizontal movement of the reversing cross shaft.

[0006] Preferably, the scraper mechanism is a scraper structure bent from spring steel. One end of the scraper structure is fixedly arranged on the support rod, and the other end of the scraper structure is in a pressed state and closely adheres to the upper part of the inner side of the bucket when the two buckets are in a closed state. When the two buckets are in an open state, the scraper structure slides down along the inner side of the bucket to the lower part of the inner side of the bucket under the elastic state as the bucket opens, completing the function of cleaning the bucket.

[0007] Preferably, the scraper mechanism includes an inclined blade support and a blade. The upper end of the blade support is fixedly arranged on the support rod, the lower end of the blade support is fixedly provided with a blade, the cutting edge of the blade faces downward, and the outer shape of the blade matches the shape of the inner side wall of the ground cylinder.

[0008] Furthermore, a protective cover is arranged on the upper side of the bucket. The lower end of the protective cover is matched and arranged on the upper side edge of the bucket, and the upper end of the protective cover is arranged on the protective cover connecting plate fixed to the support rod.

[0009] Furthermore, a protective plate is wrapped around the outer sides of the reversing horizontal shaft, the connecting rod and the actuating rod of the scraping cylinder. The reversing horizontal shaft penetrates through the protective plate.

[0010] Furthermore, a serrated edge is arranged at the lower end excavation part of the bucket.

[0011] Furthermore, the two support rods are symmetrically arranged on both sides of the robot end connecting plate, the two scraping cylinder cylinders are symmetrically arranged on the two support rods, and each scraping cylinder cylinder drives a scraping cylinder plate through a connecting rod.

[0012] The beneficial effects of the present invention compared with the prior art are as follows: The present invention drives the bucket to open and close for material taking through the bucket electric cylinder, and drives the robot end connecting plate to rotate through the robot to drive the scraping cylinder plate to rotate along the inner wall of the ground cylinder for cylinder cleaning. During the process of the bucket opening for discharging, the scraper mechanism remains stationary, and the relative movement generated between the two causes the scraper mechanism to scrape off the sticky material on the inner wall of the bucket. At the same time, the arranged protective cover can ensure that the material will not be scattered, reducing material loss and cleaning work. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment

[0026] The present invention will be further described below in conjunction with specific embodiments. Embodiment

[0027] Such as Figures 1 to 8As shown in the figure, this embodiment relates to a material-taking bucket applicable to the fermented material in the ground cylinder, including a robot end connecting plate 1, a bucket electric cylinder 2, a herringbone connecting rod 3, a bucket main shaft 4, a bucket connecting shaft 5, and a bucket 6. The cylinder body of the bucket electric cylinder 2 is fixed to the lower side of the robot end connecting plate 1. The upper side of the robot end connecting plate 1 is connected to the robot execution end to realize multi-degree-of-freedom motions including rotation and movement. The execution end of the bucket electric cylinder 2 is connected to the upper ends of at least one herringbone connecting rod 3 through a lifting cross bar 7. The lower ends of the herringbone connecting rods 3 are all connected with bucket connecting shafts 5. Both ends of the bucket main shaft 4 are connected to the rotation centers of two symmetrically arranged buckets 6. Both ends of the two bucket connecting shafts 5 are respectively connected to the lifting sections of the two buckets 6, so that the two buckets 6 are driven by the bucket electric cylinder 2 to open and close. A support rod 8 is vertically arranged on the robot end connecting plate 1. The lower end of the support rod 8 is sleeved on the bucket main shaft 4. The bucket 6 is a polyhedron structure. A scraping mechanism 9 is arranged on the support rod 8. The execution end of the scraping mechanism 9 is arranged to fit tightly against the inner wall of the bucket 6, and the scraping function is realized during the opening and closing process of the bucket 6.

[0028] A scraping cylinder 10 is arranged on the support rod 8. The cylinder body of the scraping cylinder 10 is fixedly arranged on the support rod 8. The execution rod of the scraping cylinder 10 is movably connected to a reversing cross shaft 12 through a connecting rod 11. The reversing cross shaft 12 is driven by the scraping cylinder 10 to move horizontally back and forth. A scraping cylinder plate 13 is vertically movably arranged at the outer end of the reversing cross shaft 12. The outer contour of the scraping cylinder plate 13 is arranged to match the shape of the inner wall of the ground cylinder. The scraping cylinder plate 13 is pressed against the inner wall of the ground cylinder through the horizontal movement of the reversing cross shaft 12.

[0029] The scraping mechanism 9 is a scraping structure bent from spring steel. One end of the scraping structure is fixedly arranged on the support rod 8. The other end of the scraping structure is in a pressed state and tightly adheres to the upper part inside the bucket 6 when the two buckets 6 are in the closed state. When the two buckets 6 are in the open state, the scraping structure slides down along the inner side of the bucket 6 to the lower part inside the bucket 6 under the action of the elastic force as the bucket 6 opens, completing the function of cleaning the bucket.

[0030] In the present invention, since the fermented material is relatively sticky, during the process of digging the material, the material will stick to the inner wall of the bucket, resulting in incomplete pouring or difficult cleaning of the material. Therefore, the spring steel is bent into a scraping plate inside the bucket, and the high elasticity of the spring steel is used to realize scraping. When the bucket is in the open state, the scraping plate is at the lower part of the bucket. When digging the material, due to the upward thrust of the material on the scraping plate, the scraping plate reaches the upper cross-section position of the bucket. When the bucket is in the state of discharging the material, the scraping plate automatically resets under the action of its own elasticity.

[0031] A protective cover 16 is arranged on the upper side of the bucket 6. The lower end of the protective cover 16 is arranged to match the upper side edge of the bucket 6. The upper end of the protective cover 16 is arranged on a protective cover connecting plate 17 fixed to the support rod 8.

[0032] The outer sides of the reversing horizontal axis 12 , the connecting rod 11 and the actuator rod of the scraper cylinder 10 are wrapped with a protective plate 18 , and the reversing horizontal axis 12 passes through the protective plate 18 . The penetrating portion of the reversing horizontal axis 12 can also limit the lateral movement of the reversing horizontal axis 12 .

[0033] The lower excavation portion of the bucket 6 is provided with a serrated edge.

[0034] The two support rods 8 are symmetrically arranged on both sides of the robot end connecting plate 1 , and the two scraper cylinders 10 are symmetrically arranged on the two support rods 8 . Each scraper cylinder 10 drives a scraper plate 13 through a connecting rod 11 . Example

[0035] like Figures 9 to 11 As shown, in this embodiment, the scraper mechanism 9 includes an inclined blade support 14 and a blade 15, the upper end of the blade support 14 is fixedly arranged on the support rod 8, and the lower end of the blade support 14 is fixedly arranged with the blade 15, the blade 15 faces downward, and the shape of the blade 15 matches the shape of the inner wall of the ground cylinder. The remaining features of this embodiment are the same as those of the first embodiment.

[0036] In the present invention, when the bucket is in a closed state and the teeth are just tangent to the bottom of the cylinder, the circular cross-section of the cylinder corresponding to the upper cross-section of the bucket is the maximum size of the designed upper cross-section of the bucket. Therefore, the maximum value of the upper cross-section of the bucket is found in the cross-section inside the circle, and the N-gon is similar to a circle. Therefore, the more sides the upper cross-section of the bucket has, the larger the volume of the bucket. However, considering that the sheet metal process and stamping cost of the bucket are relatively high, the bucket is determined to be an octagon, which can be bent into shape at one time, saving costs and achieving more material extraction under the condition of the cylinder being "large on the top and small on the bottom".

[0037] In the present invention, since the fermented material in the ground cylinder has high viscosity, the material is adhered to the cylinder wall during the material removal process and is difficult to automatically fall into the cylinder. Therefore, the cylinder drives the connecting rod to realize the scraping function in the ground cylinder. A scraping cylinder plate is installed at the end of the reversing horizontal axis. The scraping cylinder plate adopts a hinge structure. When the scraping cylinder plate touches the cylinder wall at point B, point A will be closely attached to the cylinder wall. A certain movable space is left at point C, so that the scraping cylinder plate is completely attached to the inner wall of the cylinder to prevent it from being stuck with the cylinder wall, causing damage to the cylinder and the scraper.

[0038] In the process of excavating and discharging materials, the present invention inevitably causes materials to fall during the process, and the operators need to spend time to clean them up. Therefore, elastic cloth is used to wrap the upper section of the bucket to the lower side of the support rod reinforcement rib, so that the bucket will not drop materials during the movement.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
