Abstract
Description
Technical Field
[0001] The present invention relates to the field of grain processing, and more specifically, to an inner sieve cylinder of a grain drum sieve. Background Art
[0002] A drum sieve is a common screening device widely used in material classification and cleaning in various industries. It screens and classifies materials by using a rotary drum, and has the advantages of simple structure, convenient maintenance, strong processing capacity, etc. It is applicable to a variety of materials such as plastics, grains, sands, soils, metal ash, screws, fruits, tea leaves, dehydrated vegetable powders, etc.
[0003] The size of the inner cylinder sieve holes of the drum sieve is fixed, and the sieve holes are determined by the gaps between the sieve plates. Once the sieve plates are welded and fixed, only materials of a specific size can be screened, which cannot meet the needs of screening different materials. Especially for the screening of grains, inner sieve cylinders with different sieve holes need to be customized according to different grains, and the applicability is poor. Therefore, it is necessary to improve the structure of the inner sieve cylinder so that its sieve holes can be adjusted. Summary of the Invention
[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an inner sieve cylinder of a grain drum sieve, which is more flexible, practical and has stronger applicability compared with the traditional sieve cylinder.
[0005] To solve the above problems, the present invention adopts the following technical solutions.
[0006] An inner sieve cylinder of a grain drum sieve includes sieve plates, locking rings and joint outer hoops. Docking heads are symmetrically welded at both ends of the sieve plates, and there are multiple sieve plates. A trapezoidal groove is opened on one side of the docking head. Trapezoidal plugs are evenly welded on one side of the locking ring. The trapezoidal plugs correspond to the docking heads one by one, and the trapezoidal plugs are inserted and installed inside the trapezoidal grooves.
[0007] Further, there are two locking rings, and a conical frame is welded on one side of the locking ring. A frame top cap is arranged at the end of the conical frame.
[0008] Further, a tension screw rod passes through between the two frame top caps, and a nut is nested at one end of the tension screw rod.
[0009] Further, the joint outer hoop is nested outside multiple docking heads.
[0010] Further, a bolt is installed on one side of the joint outer hoop.
[0011] Compared with the prior art, the advantages of the present invention are as follows: The sieve plate of this solution is installed between two locking rings. By adjusting the distance between the two locking rings, the distance between the sieve plates can be adjusted, realizing the adjustment of the sieve hole size of the sieve cylinder. It can be adjusted according to the material to be screened, without replacing the entire sieve cylinder, which is more flexible and practical than the traditional sieve cylinder and has stronger applicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0015] Please refer to Figures 1-11, A grain drum sieve inner sieve cylinder, comprising a sieve plate 101, a locking ring 102 and a joint outer hoop 103. At both ends of the sieve plate 101, butt joints 111 are symmetrically welded, and a plurality of sieve plates 101 are provided. On one side of the butt joint 111, a trapezoidal groove 112 is formed. On one side of the locking ring 102, trapezoidal plugs 121 are uniformly welded. The trapezoidal plugs 121 correspond to the butt joints 111 one by one, and the trapezoidal plugs 121 are inserted and installed inside the trapezoidal grooves 112. With such a setting, by changing the distance between the two locking rings 102, the depth of insertion of the trapezoidal plugs 121 into the trapezoidal grooves 112 changes, thereby realizing the adjustment of the position and spacing of the sieve plates 101.
[0016] Refer to Figures 1-5 , There are two locking rings 102, and a conical frame 104 is welded on one side of the locking ring 102. At the end of the conical frame 104, there is a frame top cap 141. With such a setting, the conical conical frame 104 does not affect the material entering the sieve cylinder.
[0017] Refer to Figures 1-5 , A tension screw rod 105 passes through between the two frame top caps 141. One end of the tension screw rod 105 is nested with a nut. With such a setting, it is convenient to fasten the two locking rings 102.
[0018] Refer to Figures 1-4 , The joint outer hoop 103 is nested on the outside of a plurality of butt joints 111. With such a setting, it is convenient to fasten a plurality of sieve plates 101 and prevent the positions of the sieve plates 101 from changing.
[0019] Refer to Figures 1-4 , A bolt is installed on one side of the joint outer hoop 103. With such a setting, it is convenient to fix the joint outer hoop 103 on the outside of the butt joint 111.
[0020] During use: First, install the sieve plates 101 one by one between the two locking rings 102. When installing, insert the butt joints 111 at the ends of the sieve plates 101 outside the trapezoidal plugs 121. Then adjust the tension screw rod 105 to adjust the distance between the two locking rings 102. Next, nest the joint outer hoop 103 on the outside of the butt joint 111 and screw and tighten the bolt of the joint outer hoop 103 to fix the plurality of sieve plates 101.
