Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 1-2, in order to prolong the service life of the bucket elevator, the embodiment of the utility model provides a protective device for a bucket elevator, which comprises an elevator body 1, wherein a feed hopper 2 is arranged at the bottom of the elevator body 1, a partition plate 7 which is pushed to lift by a hydraulic cylinder 3 is arranged at the bottom in the elevator body 1, a weighing module 6 which is used for adjusting the extension of a piston rod 4 of the hydraulic cylinder 3 according to the weight value is arranged at the joint of the partition plate 7 and the hydraulic cylinder 3, the partition plate 7 is arranged below the feed hopper 2, and the top of the partition plate 7 is connected with a baffle plate 10 which can seal an opening, which is connected with the elevator body 1, of the feed hopper 2 when moving in the vertical direction.

The movable end of the piston rod 4 is fixedly connected with the lifting platform 5, the weighing module 6 is fixed on the lifting platform 5, the partition plate 7 is fixed on the weighing module 6, the weighing module 6 is an existing electronic scale and is combined with a single chip microcomputer, borne pressure and set pressure can be compared, and then a control signal is transmitted to a power control unit of the hydraulic cylinder. When the bucket elevator is loaded, materials are poured into the feed hopper 2 through a truck, the materials enter the machine body 1 through an opening at the joint of the machine body 1 and the feed hopper 2, the partition plate 7 supports the materials in the machine body 1, the weighing module 6 weighs the materials on the partition plate 7, and the obtained numerical value is compared with the set maximum material carrying amount of stable operation of the bucket elevator;

when actual materials in the machine body 1 are more than the maximum loading capacity of the bucket elevator in the stable state, the piston rod 4 of the hydraulic cylinder 3 is controlled to contract through the power control unit of the hydraulic cylinder, so that the partition plate 7 descends, meanwhile, the baffle plate 10 is driven by the partition plate 7 to move downwards, the opening between the machine body 1 and the feed hopper 2 is partially shielded, the feeding capacity of the materials is reduced, the contact area of the hopper in the machine body 1 and the materials is reduced, the resistance when the hopper is in contact with the materials is reduced, the hopper and the motor are further protected, finally, the material entering amount in the machine body 1 in unit time is controlled to be equal to the material conveying amount of the bucket elevator, and the integral stable work of the bucket elevator is realized;

after the material in the feeding hopper 2 completely enters the machine body 1, along with the continuous reduction of the material on the partition plate 7, the power control unit of the hydraulic cylinder 3 controls the piston rod 4 to extend out, so that the partition plate 7 moves upwards, and the material on the partition plate 7 is completely lifted by the hopper. The hopper (semi-elliptical structure in fig. 2) is a material loading container for lifting materials by a conventional bucket elevator, and can automatically load materials at the bottom in the bucket elevator when moving along with a chain of the bucket elevator.

As shown in fig. 2, in order to ensure that the material on the partition plate 7 is completely lifted, the partition plate 7 is in an arc shape protruding downwards, and the diameter of the arc shape is not less than the width of the machine body 1. In-process that the material was promoted on baffle 7, remaining material can pile up in the centre at baffle 7 top, needs to promote the material in the hopper built-in baffle 7 this moment, need avoid the both ends contact of hopper and baffle 7 simultaneously, consequently when the diameter of baffle 7 is not less than organism 1's width, the hopper can carry out complete promotion to the material on the baffle 7, avoids the both ends contact of hopper and baffle 7 simultaneously.

As shown in fig. 2-3, for the stability of promotion baffle 10, between organism 1 and the feeder hopper 2 the opening part lateral wall is outside protrusion, baffle 10 and the laminating of the inner wall of organism 1, the opening part between organism 1 and the feeder hopper 2 evenly is provided with vertical guide post 9, and guide post 9 runs through baffle 10, the area of baffle 10 is not less than the open-ended area. When the entering amount of the material in the machine body 1 needs to be limited by the baffle 10, the material in the feed hopper 2 applies the pressure to the baffle 10 in the horizontal direction, and the baffle 10 is supported by the guide columns 9, so that the stability of the baffle 10 can be effectively improved.

As shown in fig. 2, in order to enhance the stability of the movement of the partition 7, the partition 7 is fixedly connected with the baffle 10 through a connecting rod 12, a guide ring 11 is fixedly arranged on the inner wall of the machine body 1, and the connecting rod 12 passes through the guide ring 11. Baffle 7 keeps away from the side fixed connection of feeder hopper 2 through connecting rod 12 and baffle 10, carries out spacingly through guide ring 11 to connecting rod 12 in, realizes spacing to baffle 7, can increase the stability that baffle 7 removed.

As shown in fig. 2, in order to prevent the material scattered from the partition 7 from affecting the hydraulic cylinder 3, a guide plate 8 for the piston rod 4 to pass through is disposed at the bottom of the machine body 1. Although the edge of the partition plate 7 is attached to the inner wall of the machine body 1, the falling of materials on the partition plate 7 cannot be avoided in the use process, the guide plate 8 not only guides the piston rod 4, but also serves as a partition to separate the hydraulic cylinder 3 from the partition plate 7, so that the materials are prevented from falling on the hydraulic cylinder 3; can open on organism 1 and establish the collection hole for collect the recovery from the material that falls on baffle 7, the collection hole is seted up in the top of deflector 8.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
