Description

Technical Field

[0001] This utility model relates to the field of coconut shell raw material processing technology, specifically a reciprocating gear screen. Background Technology

[0002] In existing technologies, when crushing coconut shells, the shearing force generated during the rotation of the crushing roller is usually used to break the coconut shells. Although the operation is relatively simple, the shearing force applied to the coconut shells during the crushing process is unidirectional, which can easily cause some coconut shells to be over-crushed while others are under-crushed. As a result, the particle size of the crushed coconut shell fragments is not consistent, which is not conducive to the processing of coconut shells in subsequent stages.

[0003] Therefore, there is an urgent need for a reciprocating gear screen to solve the above problems. Utility Model Content

[0005] The coarse crushing assembly includes a plurality of first rotating rods rotatably connected between two opposite inner walls of the crushing box, each first rotating rod having a crushing blade fixedly connected to its side wall, and adjacent crushing blades being staggered.

[0006] The fine crushing assembly includes a second rotating rod rotatably connected between two opposite inner walls of the crushing box. Each second rotating rod has multiple crushing components on its side wall. Each crushing component includes multiple crushing plates, which are arranged in a ring array.

[0007] The individual crushing components are arranged in an alternating pattern between adjacent pairs.

[0008] Each of the second rotating rods is located below the first rotating rod, and the second rotating rods and the first rotating rod are arranged perpendicularly and alternately.

[0010] The rotating assembly includes two rotating shafts rotatably connected to the side of the crushing box near the drive gear. The two rotating shafts are located on both sides of the drive gear and are arranged in an inclined and symmetrical manner.

Detailed Implementation

[0019] 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.

[0020] Example 1

[0021] Please see Figures 1-4 The reciprocating gear screen shown in the figure includes a base plate 101 and a crushing box 102 disposed on one side of the base plate 101. The crushing box 102 is connected to the base plate 101 by four L-shaped support legs 103 arranged symmetrically in pairs. A conical feeding port 104 is fixedly connected to the side of the crushing box 102 away from the base plate 101. The screen also includes a coarse crushing component disposed in the crushing box 102 for preliminary crushing of coconut shell raw materials and a fine crushing component for screening and fine crushing of coconut shell raw materials after coarse crushing.

[0022] The coarse crushing assembly includes a plurality of first rotating rods 201 rotatably connected between two opposite inner walls of the crushing box 102. Each first rotating rod 201 has a crushing blade 202 fixedly connected to its side wall. Two adjacent crushing blades 202 are staggered. The rotation mode of each first rotating rod 201 can be the same as the rotation mode of each second rotating rod 301.

[0023] The fine crushing assembly includes a second rotating rod 301 rotatably connected between two opposing inner walls of the crushing box 102. Each second rotating rod 301 has multiple crushing components on its side wall. Each crushing component includes multiple crushing plates 302. The crushing plates 302 are arranged in a ring array. The crushing box 102 is a drive assembly for driving each crushing component.

[0024] It should be noted here that: by setting up coarse and fine crushing components, and with the cooperation of the drive component, rotation component, and linkage component, the coconut shell is subjected to extrusion and shearing forces from multiple directions. Under the multi-directional and repetitive force, the coconut shell is crushed more uniformly, thereby improving the consistency of the coconut shell fragment particle size. At the same time, during the crushing process, crushed coconut shells that meet the particle size requirements will fall through the gaps between the various crushing plates 302, thus realizing the screening of the coconut shell during the crushing process.

[0025] Please see Figure 2 The broken pieces in the diagram are arranged in an alternating pattern between adjacent pairs;

[0026] It should be noted here that: the ventilation system, by staggering the adjacent crushing components, can improve the overall effectiveness of coconut shell crushing.

[0027] Please see Figure 2 In the figure, each of the second rotating rods 301 is located below the first rotating rod 201, and each of the second rotating rods 301 and the first rotating rod 201 are arranged perpendicularly and alternately.

[0028] It should be noted that by placing each of the second rotating rods 301 below the first rotating rod 201, and by arranging each of the second rotating rods 301 and the first rotating rod 201 in a vertically staggered manner, it is convenient to form a multi-directional crushing of the coconut shell.

[0029] Please see Figure 3 and Figure 4 The drive assembly shown in the figure includes a plurality of drive rods 401 rotatably connected to one side of the crushing box 102. One end of each drive rod 401 is connected to a second rotating rod 301. A drive gear 402 is fixedly connected to the side wall of each drive rod 401. The drive gears 402 are meshed with each other. The crushing box 102 is provided with a rotating assembly for reciprocating rotation of each drive gear 402.

[0030] It should be noted here that: by setting the drive components, while driving each crushing component to rotate, the rotation directions of two adjacent crushing components are made to be opposite.

[0031] Please see Figure 3 and Figure 4 The rotating assembly shown in the diagram includes two rotating shafts 501 rotatably connected to the side of the crushing chamber 102 near the drive gear 402. The two rotating shafts 501 are located on both sides of the drive gear 402 and are arranged obliquely and symmetrically. Sector gears 502 are fixedly connected to the side walls of the two rotating shafts 501 respectively, and the two sector gears 502 are respectively meshed with two adjacent drive gears 402 (see reference). Figure 4 The crushing box 102 is equipped with a linkage assembly for linking the two sector gears 502.

[0032] It should be noted here that the rotating component is designed to facilitate the reciprocating rotation of the drive gear 402.

[0033] Working principle: When crushing coconut shell raw materials, the coconut shell raw materials are first fed into the crushing box 102 through the conical feeding port 104 using a feeding machine. When the coconut shell raw materials are fed into the crushing box 102, the crushing blades 202 on multiple first rotating rods 201 are rotated. Under the rotation action of the various staggered crushing blades 202, the coconut shell raw materials are sheared and crushed, thereby realizing the initial processing and crushing of the coconut shell raw materials.

[0034] After initial crushing by the individual crushing blades 202, the coconut shell material falls onto the second rotating rods 301 under gravity. At this point, the linkage assembly drives two sector gears 502 to rotate synchronously. During the rotation of the two sector gears 502, when one of them meshes with the drive gear 402, it drives the drive gear 402 to rotate. This, in turn, through the meshing transmission of the drive gears 402, causes the crushing plates 302 on the second rotating rods 301 to rotate. Furthermore, due to the meshing of adjacent drive gears 402, adjacent second rotating rods 301 rotate in opposite directions, resulting in adjacent crushing components rotating in opposite directions. This creates multiple shearing and crushing forces on the coconut shell material. Meanwhile, when the other of the two sector gears 502 meshes with the adjacent drive gear 402, it will drive the drive gear 402 to rotate in the opposite direction, which in turn drives each crushing plate 302 to rotate in the opposite direction. Through the reciprocating meshing of the two sector gears 502 with the drive gear 402 and the meshing action between each drive gear 402, each crushing plate 302 rotates back and forth, thereby applying extrusion and shearing forces to the coconut shell from multiple directions. Under the multidirectional and repetitive forces, the coconut shell is crushed more uniformly, improving the consistency of the coconut shell fragment particle size. At the same time, during the crushing process, crushed coconut shells that meet the particle size requirements will fall from the gaps between the crushing plates 302, thus realizing the screening of the coconut shell during the crushing process.

[0035] Example 2

[0036] Please see Figure 4 This embodiment further illustrates Example 1. The linkage component shown in the figure includes a U-shaped plate 601 fixedly connected to the side of the crushing box 102 near the sector gear 502. Two transmission wheels 602 are provided on the side of the U-shaped plate 601 near the crushing box 102. The two transmission wheels 602 are respectively connected to two rotating shafts 501. The two transmission wheels 602 are connected to each other by a transmission belt 603. A motor 604 is fixedly connected to the side of the U-shaped plate 601 away from the crushing box 102. The output end of the motor 604 is connected to one of the two rotating shafts 501.

[0037] It should be noted here that: through the setting of the linkage component, the rotation of the motor 604 drives one of the two rotating shafts 501 to rotate, and then, under the transmission action of the two transmission wheels 602 and the transmission belt 603, drives the other rotating shaft 501 to rotate, thereby causing the sector gears 502 on the side walls of the two rotating shafts 501 to rotate synchronously.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
