Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a bowl-type elevator. Background Art

[0002] Bowl elevator is a lifting equipment used for solid materials such as small blocks and granules. It usually adopts non-toxic PP anti-stick hopper, which can be quickly disassembled and easy to clean. It can be matched with bag-feeding packaging machine to realize the packaging of solid-liquid mixture materials. For product materials that cannot be automatically measured, they are poured into the bowl through manual measurement, and then the bowl elevator pours the materials into the bag opened on the bag-feeding packaging machine. For products equipped with electronic combination scales for automatic measurement, after the electronic scale automatically weighs the material, it first falls into the bowl elevator and then is poured into the bag through the bowl elevator. This method is usually used when the factory building is not high enough. At present, the bowl of the bowl elevator needs to be dismantled and maintained after a period of use, and corresponding operations are also required when changing the conveying material.

[0003] The existing Chinese patent (application number: 202022960970.X) proposes an easily detachable bowl-type lifting device, which uses a pull plate fixing unit to rotate the rear end of the opening and closing pull plate and install it on the bottom plate of the bowl, and uses a pull plate sliding unit to enable the front end of the opening and closing pull plate to slide on the slide groove. The two opening and closing pull plates are used to clamp the bowl and fix it to the bottom plate of the bowl. The spring generates tension between the two pull plate sliding units, which can make the opening and closing pull plate tightly clamp the lower end of the bowl. The pull plate wrench can be used to quickly pry open the opening and closing pull plate and take out the bowl.

[0004] Although the above solution can solve the disassembly and assembly problem, it also has the following problems: since the pull plate is fixed by bolt installation, the fixing point is on the lateral vertical section of the bowl bottom plate. Even if it is unscrewed vertically or unscrewed horizontally with a wrench, the fixing part cannot be quickly disassembled, which increases the difficulty of disassembly and assembly of the bowl body and is not conducive to actual use.

[0005] In view of this, this application is hereby filed. Utility Model Content

[0006] The purpose of the present utility model is to provide a bowl elevator to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides a bowl-type elevator, which includes a bottom plate, a connecting hole, a mounting plate, and a bowl body.

[0008] A connecting hole is provided at the bottom front end of the base plate, and the connecting hole is installed and connected to the chain conveyor. A mounting plate is installed in the middle of the top surface of the base plate, and two mounting plates are provided at intervals. Mounting holes are provided on the sides of the mounting plate. Connecting plates are installed on both sides of the bottom of the bowl body. The connecting plate has an L-shaped structure as a whole, and side holes corresponding to the mounting holes of the mounting plate are provided on the sides of the vertical section of the connecting plate.

[0009] In one embodiment, a bottom rod is installed at the bottom center of the bowl body, and plug blocks are installed on both sides of the bottom rod. The plug blocks are generally rectangular in structure. A bottom hole is opened at the center of the bottom surface of the bottom rod, and the bottom hole is an internal threaded hole.

[0010] In one embodiment, a positioning mechanism is installed in the middle of the bottom plate, the positioning mechanism is located between the mounting plates, and the main body of the positioning mechanism is arranged vertically corresponding to the bottom rod.

[0011] In one embodiment, the main body of the positioning mechanism is a positioning box, which is a hollow cylindrical structure as a whole. The top surface of the positioning box is open, and a first limiting portion and a second limiting portion are installed inside the positioning box.

[0012] In one embodiment, the first limiting portion is composed of a limiting plate, a socket, a positioning groove, and a circular opening. The limiting plate is a circular plate structure as a whole, with a circular opening in the middle, the diameter of the circular opening is consistent with the diameter of the bottom rod, the limiting plate is provided with sockets on both sides of the circular opening, the internal dimensions of the sockets are matched with the dimensions of the plug-in block, the front and rear end bottoms of the limiting plate are provided with positioning grooves, the internal dimensions of the positioning grooves are consistent with the dimensions of the plug-in block, and the positioning grooves and sockets are arranged at ninety degrees on the limiting plate.

[0013] In one embodiment, the second limiting portion is composed of an extrusion plate, a spring telescopic rod, and a threaded head. The extrusion plate is located below the limiting plate. The bottom of the extrusion plate is installed and connected to the telescopic end of the spring telescopic rod. The bottom of the spring telescopic rod is installed and connected to the inner bottom surface of the positioning box. A threaded head is installed at the center of the top surface of the extrusion plate.

[0014] In one embodiment, the bowl body is installed with two and a half rotations. The two and a half rotations can make the installation of the threaded head and the bottom rod more stable, and can also allow the insert to smoothly enter the positioning groove after rotating two and a half turns. At the same time, the connecting plate and the mounting plate can still be installed with each other under the rotation path of two and a half turns.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Place the bottom of the bowl on the top surface of the bottom plate, so that the connecting plate enters the inner side of the mounting plate, leaving a gap between the two. Screw the fixing bolts into the mounting hole of the mounting plate and the side hole of the connecting plate to complete the installation of the bowl. Insert the bottom rod into the round opening so that the plug is synchronously inserted under the socket. Rotate the bowl to drive the bottom rod and the plug to rotate synchronously, so that the top surface of the plug is in contact with the inner top surface of the positioning groove, so that the limit plate serves as an auxiliary limit for the bottom rod and the plug, further improving the installation stability of the bowl and avoiding the problem of the bowl being dislocated due to loosening of the fixing bolts.

[0017] 2. The plug-in block of the bottom rod enters the positioning groove more stably under the resetting action of the spring telescopic rod, providing a second limit protection, further improving the stability of the bowl body installation. At the same time, the structural connection effect is better than the clamping means in the background technology, and it also avoids relying solely on the extrusion force when the pull plate is clamped and ignoring the rotatability of the arc pull plate and the bowl bottom structure, so that the overall structure has stability and is easy to disassemble and assemble.

The connecting plate 41 is an L-shaped structure as a whole, and side holes corresponding to the mounting holes of the mounting plate 3 are provided on the sides of the vertical section of the connecting plate 41. During operation, the bottom of the bowl body 4 is placed on the top surface of the base plate 1, so that the connecting plate 41 enters the inner side of the mounting plate 3, leaving a distance between the two, and fixing bolts are screwed into the mounting holes of the mounting plate 3 and the side holes of the connecting plate 41 to complete the installation of the bowl body 4.

[0026] Preferably, in one embodiment, Figure 1-Figure 2 As shown, a bottom rod 42 is installed at the bottom center of the bowl body 4, and plug blocks 43 are installed on both sides of the bottom rod 42. The plug blocks 43 are generally rectangular in structure, and a bottom hole is opened at the center of the bottom surface of the bottom rod 42, and the bottom hole is an internal threaded hole.

[0027] Preferably, in one embodiment, Figure 1-Figure 2 As shown, a positioning mechanism 5 is installed in the middle of the base plate 1 , and the positioning mechanism 5 is located between the mounting plates 3 . The main body of the positioning mechanism 5 is vertically corresponding to the bottom rod 42 .

[0028] Preferably, in one embodiment, Figure 2-Figure 3 As shown, the main body of the positioning mechanism 5 is a positioning box 51 , which is a hollow cylindrical structure as a whole. The top surface of the positioning box 51 is open, and a first limiting portion and a second limiting portion are installed inside the positioning box 51 .

[0029] Preferably, in one embodiment, Figure 3-Figure 4As shown, the first limiting portion is composed of a limiting plate 54, a socket 55, a positioning groove 56, and a circular opening 57. The limiting plate 54 is a circular plate structure as a whole, and a circular opening 57 is opened in the middle thereof. The diameter of the circular opening 57 is consistent with the diameter of the bottom rod 42. The limiting plate 54 is provided with sockets 55 on both sides of the circular opening 57. The internal size of the socket 55 matches the size of the plug 43. The front and rear end bottoms of the limiting plate 54 are provided with positioning grooves 56. The internal size of the positioning grooves 56 matches the size of the plug 43. The sizes are consistent, and the positioning groove 56 and the socket 55 are arranged at a ninety-degree position on the limit plate 54. During operation, by inserting the bottom rod 42 into the circular opening 57, the plug block 43 is synchronously entered under the socket 55, and the bowl body 4 is rotated to drive the bottom rod 42 and the plug block 43 to rotate synchronously, so that the top surface of the plug block 43 abuts against the inner top surface of the positioning groove 56, so that the limit plate 54 plays an auxiliary role in limiting the bottom rod 42 and the plug block 43, further improving the installation stability of the bowl body 4, and avoiding the problem of the bowl body 4 being dislocated due to the loosening of the fixing bolts.

[0030] Preferably, in one embodiment, Figure 3-Figure 4 As shown, the second limiting portion is composed of an extrusion plate 52, a spring telescopic rod 53, and a threaded head 58. The extrusion plate 52 is located below the limiting plate 54. The bottom of the extrusion plate 52 is installed and connected to the telescopic end of the spring telescopic rod 53. The bottom of the spring telescopic rod 53 is installed and connected to the inner bottom surface of the positioning box 51. A threaded head 58 is installed at the center of the top surface of the extrusion plate 52. When working, after the bottom rod 42 is inside the positioning box 51, the bottom hole at the bottom of the bottom rod 42 is abutted against the threaded head 58. By pressing down the bottom rod 42, the extrusion plate 52 and the spring telescopic rod 53 are connected. As the bottom rod 42 moves downward, the bottom hole of the bottom rod 42 engages with the threaded head 58 as the bottom rod 42 rotates. After the connection is completed, the bowl body 4 is loosened, so that the plug 43 of the bottom rod 42 can enter the positioning groove 56 more stably under the resetting action of the spring telescopic rod 53, providing a second limit protection, further improving the stability of the installation of the bowl body 4, and at the same time, the structural connection effect is better than the clamping means in the background technology, and it also avoids relying solely on the extrusion force when the pull plate is clamped and ignoring the rotatability of the arc pull plate and the bowl bottom structure, so that the overall structure has stability and convenient disassembly and assembly operability.

[0031] Preferably, in one embodiment, Figure 3-Figure 4 As shown, the bowl body 4 is installed and rotated two and a half turns. The two and a half turns can make the installation of the threaded head 58 and the bottom rod 42 more stable, and at the same time, the insert 43 can smoothly enter the positioning groove 56 after rotating two and a half turns. At the same time, the connecting plate 41 and the mounting plate 3 can still be installed with each other under the rotation path of two and a half turns, and the distance between the two can adapt to the influence of the cutting angle during rotation, and no mutual blocking will occur.

[0032] Working principle:

[0033] After the bottom of the bowl body 4 is placed on the top surface of the bottom plate 1, the connecting plate 41 enters the inner side of the mounting plate 3, leaving a gap between the two, and the fixing bolts are screwed into the mounting hole of the mounting plate 3 and the side hole of the connecting plate 41 to complete the installation of the bowl body 4. By inserting the bottom rod 42 into the inside of the circular opening 57, the plug block 43 is synchronously entered under the socket 55, and the bowl body 4 is rotated to drive the bottom rod 42 and the plug block 43 to rotate synchronously, so that the top surface of the plug block 43 abuts against the inner top surface of the positioning groove 56, so that the limit plate 54 plays an auxiliary limit role for the bottom rod 42 and the plug block 43. By pressing the bottom rod 42 downward, the extrusion plate 52 and the spring telescopic rod 53 move downward. As the bottom rod 42 rotates, the bottom hole of the bottom rod 42 is engaged with the threaded head 58. After the connection is completed, the bowl body 4 is loosened, so that the plug block 43 of the bottom rod 42 can enter the positioning groove 56 more stably under the resetting action of the spring telescopic rod 53, providing a second limit protection.
