Description

Technical Field

[0001] This utility model relates to the field of bucket processing technology, specifically to an adjustable bucket punching device. Background Technology

[0002] Grain elevators are commonly used agricultural machines, mainly used to lift grain from a low place to a high place. They are widely used in grain depots, feed mills, flour mills, and other places. For example, during the processing of grain elevator buckets, in order to facilitate their connection and installation with other components, mounting holes need to be drilled symmetrically on the buckets. However, since the mounting components of the buckets are not all the same, the hole spacing varies greatly. However, in the current bucket drilling and punching machine, the bucket is generally drilled and punched with a single drill bit. After one mounting hole is drilled, the bucket needs to be moved and repositioned before the mounting hole in the other position can be drilled. This is inconvenient. Therefore, we propose an adjustable bucket punching device to solve the above problems. Utility Model Content

Two bidirectional lead screws are rotatably connected between the two horizontal plates via bearings, and each end of the two bidirectional lead screws is threaded with a movable screw whose surface thread is adapted to its own. The moving blocks have their bottom ends sliding through the support plate and extending below it. The top of each moving block is rotatably connected to a T-shaped shaft via a bearing. The bottom ends of each T-shaped shaft extend below the support plate and are fitted with drill bits. The top of the support plate is equipped with a transmission mechanism for simultaneously driving the two T-shaped shafts to rotate. Two displacement sensors are fixed inside a strip-shaped groove on the top of the support plate. An installation plate is fixed inside an opening on the top of the support plate. A receiving bucket assembly for collecting debris after drilling is provided below the support plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, an adjustable bucket punching device according to one embodiment of the present invention includes a base 1, a support plate 2 fixed to the top of the base 1, two brackets 3 fixed to the top of the support plate 2, a top plate 4 fixed to the top of the two brackets 3, a cylinder 5 fixed to the top of the top plate 4, the protruding end of the cylinder 5 slidingly penetrating the top plate 4 and extending below it and fixed to a movable seat 6, four guide rods 17 slidingly penetrating the top of the top plate 4, the bottom ends of the guide rods 17 being fixedly connected to the top of the movable seat 6, which can guide and support the movable seat 6 to make it more stable during up and down movement, a bearing plate 7 fixed to the bottom of the movable seat 6, and two horizontal plates 8 fixed to the top of the bearing plate 7. Two bidirectional lead screws 9 are rotatably connected by bearings. Each bidirectional lead screw 9 has a sprocket 18 fixed to its surface. The two sprockets 18 are connected by a chain 19, allowing a single motor to simultaneously drive both bidirectional lead screws 9, thus saving production costs. Each end of the two bidirectional lead screws 9 is threaded with a movable block 10 whose surface thread is compatible. The bottom end of each movable block 10 slides through the support plate 7 and extends below it. The top of each movable block 10 is rotatably connected to a T-shaped shaft 11 via bearings. The bottom end of each T-shaped shaft 11 extends below the support plate 7 and is fitted with a drill bit 12. The top of the support plate 7 is equipped with a transmission mechanism for simultaneously driving the two T-shaped shafts 11 to rotate. 13. Two displacement sensors 16 are fixed inside the strip-shaped through-slot at the top of the support plate 7. An installation plate 14 is fixed inside the through-hole at the top of the support plate 2. A receiving bucket assembly 15 for collecting debris after drilling is provided below the support plate 2. When using this adjustable bucket drilling device, a control panel is installed on the device, which can automatically control the electrical components used in the device. By installing a clamping seat on the top of the mounting plate 14 to fix the bucket, the bucket can be placed on the clamping seat for fixation. After the bucket is installed, its center point will correspond to the center point between the two drill bits 12. When it is necessary to adjust the distance between the two drill bits 12, the motor can be started. The two bidirectional lead screws 9 rotate, and the rotation of the two bidirectional lead screws 9 can drive the two moving blocks 10 to move synchronously in opposite directions. At this time, when the displacement sensor 16 detects that the distance of the moving block 10 reaches the hole distance, the movement of the moving block 10 can be stopped. Then, the transmission mechanism 13 can drive the two T-shaped shafts 11 to rotate synchronously. After the T-shaped shafts 11 rotate, they will drive the drill bit 12 to rotate. Then, the drive cylinder 5 can drive the moving seat 6 to move down. After the moving seat 6 moves down, it can drive the rotating drill bit 12 to move down through the bearing plate 7. Then, the drilling operation can be performed on the mounting hole of the bucket. After the drilling is completed, the workers can directly push the debris on the mounting plate 14 into the inside of the receiving bucket assembly 15 for collection.

[0026] like Figure 3As shown, in some embodiments, the transmission mechanism 13 includes a connecting plate 1301 fixed to the top of the support plate 7. A cylinder 1302 is fixed to one side wall of the connecting plate 1301. The top end of the cylinder 1302 slides through the connecting plate 1301 and extends to the other side, where an L-shaped plate 1303 is fixed. A guide groove 1307 is provided on the top of the support plate 7. The L-shaped plate 1303 slides inside the guide groove 1307, which guides the L-shaped plate 1303 to make it more stable during sliding. The top of the L-shaped plate 1303 is rotatably connected to a transmission shaft 1304 via a bearing. The transmission shaft 1304 and two T-shaped... Synchronous pulleys 1305 are fixed on the surface of shaft 11. The three synchronous pulleys 1305 are connected by a synchronous belt 1306. In use, with the cooperation of the three synchronous pulleys 1305 and the synchronous belt 1306, the starting motor drives the transmission shaft 1304 to rotate, which can simultaneously drive the two T-shaped shafts 11 to rotate. When the two T-shaped shafts 11 are moving and adjusting, the cylinder 1302 will drive the L-shaped plate 1303 to move synchronously. After the L-shaped plate 1303 moves, it will drive the transmission shaft 1304 to move. At this time, the tension of the synchronous belt 1306 can be adjusted so that it will not disengage from the three synchronous pulleys 1305.

[0027] like Figure 1 and Figure 2 As shown, in some embodiments, the receiving bucket assembly 15 includes a collecting bucket 1501 that is connected and fixed to the bottom of the support plate 2. A frame 1502 is fixed at the chip discharge port opened on one side wall of the collecting bucket 1501. A baffle 1503 is tightly inserted into the slot opened at the top of the frame 1502. In use, the chips processed on the mounting plate 14 can be directly pushed down into the collecting bucket 1501 for collection. Later, the staff can open the baffle 1503 to separate it from the frame 1502, and then the collected chips can be cleaned.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
