Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a reverse-tilt air-pumping quick-install feeding mechanism. Background Art

[0002] The development of screw conveyors can be divided into two types: shaft screw conveyors and shaftless screw conveyors. Shaft screw conveyors are composed of screws, U-shaped troughs, cover plates, inlet and outlet ports, and drive devices. Generally, there are three types: horizontal, inclined, and vertical. The auger feeding mechanism can quickly and quantitatively convey bulk materials. The accuracy of quantitative conveying varies depending on the characteristics of the materials, the speed of the auger rotation, and other factors. However, the existing technology has the following shortcomings when used:

[0003] The better the fluidity of the material, the smaller the angle of repose. When the auger stops rotating, it is more likely to overshoot due to inertia, and the quantitative accuracy is more difficult to control. At the same time, the disassembly and assembly of the auger is also more inconvenient.

[0004] Therefore, there is an urgent need for a reverse-tilt air-exhaust quick-loading feeding mechanism to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to address the existing problems that the better the fluidity of the material, the smaller the repose angle, when the auger stops rotating, due to inertia, the overshoot phenomenon is more likely to occur, the quantitative accuracy is more difficult to control, and at the same time, the disassembly and assembly of the auger is also more inconvenient.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. The auger barrel, integrated quick-release auger and vacuum pump are arranged in a reverse tilted structure. On the one hand, the reverse tilt angle increases the inertial overshoot resistance, and on the other hand, it prevents the positive flow caused by the small repose angle of the material. The cleaning door is as close to the discharge port of the auger barrel as possible. The negative pressure generated by the vacuum pump is used to absorb and accumulate the material at the outlet of the auger barrel, effectively cutting off the flow of the material and preventing overshoot. The problem in the prior art that when the auger stops rotating, the overshoot phenomenon is more likely to occur due to inertia is solved.

[0019] 2. The integrated quick-release auger is set up to reduce the gap between the blade and the auger barrel, which is more conducive to material pushing and prevents material backflow. On the premise of meeting the feeding output requirements, the blade pitch is reduced, thereby reducing the material conveying speed and improving the overshoot phenomenon. At the outlet of the auger barrel, the grate installed on the integrated quick-release auger further improves the controllability of the material and solves the problem in the prior art that the quantitative accuracy of the material is more difficult to control.

[0020] 3. By setting up the first screw group and the second screw group, the bolt group is reduced from the original traditional 12 groups to 5 groups, which further simplifies the disassembly and assembly workload, facilitates the disassembly and assembly of the integrated quick-release auger, and solves the problem of inconvenient disassembly and assembly of the auger in the prior art.

[0033] like Figure 1-4 As shown, the anti-tilt air extraction quick-loading feeding mechanism proposed in the present embodiment comprises a cylinder body 1, an auger cylinder 2 is fixedly connected to the cylinder body 1, an integrated quick-release auger 3 is arranged in the auger cylinder 2, the integrated quick-release auger 3 rotates to feed, a feeding trough body 4 is fixedly connected to the auger cylinder 2, a symmetrically distributed cleaning port connecting pieces 5 are arranged on the outer wall of the auger cylinder 2, a sealing gasket 6 is arranged on the cleaning port connecting piece 5, an air extraction cleaning door 7 is arranged on the sealing gasket 6, the air extraction cleaning door 7 is fixed to the cleaning port connecting piece 5 by six bolt fixing pieces 8, a vacuum pump 9 is installed on the air extraction cleaning door 7, the vacuum pump 9 is started, air extraction begins to generate negative pressure, and the material flow rate is reduced. At this time, the starting time of the vacuum pump 9 can be adjusted according to the exhaust volume and the material punching speed, and can also be adjusted according to the operation and stop of the integrated quick-release auger 3. At different stages of stopping, the size of the exhaust volume is controlled to further control the condensation state of the material. The one-piece quick-detachable auger 3 is provided with a grate 10 located in the cylinder 1. The grate installed on the one-piece quick-detachable auger further improves the controllability of the material. An inclined cylinder seat 11 is provided on the cylinder 1, and a mounting plate 12 is provided on the inclined cylinder seat 11. The mounting plate 12 is installed on the inclined cylinder seat 11 through a first screw group 13. An end cover 14 is provided at the right end of the auger cylinder 2, and the end cover 14 is installed on the auger cylinder 2 through a second screw group 15. One end of the one-piece quick-detachable auger 3 is placed in the mounting plate 12. The first screw group 13 and the second screw group 15 are a total of 5 groups, and the bolt group is reduced from the original traditional front and rear 12 groups to 5 groups, which further simplifies the disassembly and assembly workload and facilitates the disassembly and assembly of the one-piece quick-detachable auger 3.

[0034] like Figure 1 and Figure 2As shown, the outer wall of the cylinder 1 is fixedly connected with symmetrically distributed mounting blocks 16, a connecting rod 17 is rotatably provided inside the mounting block 16, a flap door 18 is fixedly connected between the two connecting rods 17, a cylinder bracket 19 is provided on the outer wall of the cylinder 1, a Y-shaped joint 20 is provided on the connecting rod 17, a cylinder 21 is hinged on the cylinder bracket 19, a pushing end of the cylinder 21 is connected to the Y-shaped joint 20, the cylinder 21 is started, the cylinder 21 drives the connecting rod 17 to rotate through the Y-shaped joint 20, and drives the flap door 18 to rotate through the connecting rod 17, so that the flap door 18 is opened, and the integrated quick-release auger 3 is rotated to feed.

[0035] like Figure 1 As shown, a first support plate 22 and a second support plate 23 are fixedly connected to the outer wall of the auger cylinder 2 , and the first support plate 22 and the second support plate 23 support the auger cylinder 2 .

[0036] like Figure 2 As shown, the flap door 18 is located in the cylinder 1, and the cylinder 21 drives the connecting rod 17 to rotate through the Y-shaped joint 20, and drives the flap door 18 to rotate through the connecting rod 17, so that the flap door 18 is opened, and the integrated quick-release auger 3 rotates to feed materials.

[0037] like Figure 1 As shown, a rib plate 24 is fixedly connected between the cylinder body 1 and the auger cylinder 2. The rib plate 24 is provided to enhance the stability of the connection between the cylinder body 1 and the auger cylinder 2.

[0038] like Figure 1 As shown, the height from the ground of the left end of the auger barrel 2 is greater than the height from the ground of the right end of the auger barrel 2. The auger barrel 2 and the integrated quick-release auger 3 adopt a reverse tilting structural layout. On the one hand, the reverse tilting angle increases the inertial overshoot resistance, and on the other hand, it also prevents the forward flow caused by the small repose angle of the material.

[0039] like Figure 1 As shown, the cylinder support 19 is fixedly connected to the outer wall of the cylinder body 1.

[0040] Specifically, when the present anti-tilt vacuum quick-loading feeding mechanism is in use: the auger motor that controls and drives the integrated quick-release auger 3 is placed in the end cover 14, and a single feeding action control process, that is, an action cycle is taken as an example: the auger motor and the cylinder 21 are started, and the cylinder 21 drives the connecting rod 17 to rotate through the Y-shaped joint 20, and drives the flap door 18 to rotate through the connecting rod 17, so that the flap door 18 is opened, and the integrated quick-release auger 3 rotates to feed, and when the single feeding amount is reached n seconds (n=0.5~5S), the vacuum pump 9 is started, and air is pumped to generate negative pressure to reduce the material flow rate. At this time, the starting time of the vacuum pump 9 can be adjusted according to the exhaust volume and the feeding speed, and the exhaust volume can also be controlled according to the different stages of the operation and stop of the integrated quick-release auger 3 to further control the condensation state of the material to reach the single feeding amount, the integrated quick-release auger 3 stops, and the flap door 18 is turned on. The plate door 18 is closed, the feeding is completed, and the vacuum pump 9 continues to work, so that the material is adsorbed and blocked at the outlet of the auger barrel 2, and the material is cut off to prevent the material from flowing and overshooting. Before the next action cycle, that is, before the auger motor is started, the vacuum pump 9 is stopped to relieve the negative pressure. When the exhaust volume remains unchanged, the start of the vacuum pump 9 is based on the start and stop of the auger motor. Through time control, when the exhaust volume is controllable, the vacuum pump 9 can appropriately increase the advance start time. This stage can be set to a small exhaust volume. When the feeding volume is reached and the integrated quick-release auger 3 stops, the exhaust volume is increased to quickly cut off the material. This method is conducive to further improving the feeding accuracy. By setting the first screw group 13 and the second screw group 15, the bolt group is reduced from the original traditional 12 groups to 5 groups, which further simplifies the disassembly and assembly workload and facilitates the disassembly and assembly of the integrated quick-release auger 3.

Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
