Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cashew nut shell kernel screening, and specifically refers to a cashew nut shell kernel screening device. Background Art
[0002] In the field of cashew nut processing, effective screening of cashew nut shell kernels is a key link to ensure product quality and improve production efficiency. At present, a drum screen is used in the process of screening cashew nut shell kernels. The traditional drum screen usually adopts a fixed sieve hole structure in design, which means that once the equipment is manufactured, it is difficult to change the size of the sieve holes. However, in the process of screening cashew nut shell kernels, due to the differences in raw materials and the changes in production requirements, it is often necessary to flexibly adjust the size of the sieve holes to achieve the best screening effect. The existing drum screens cannot meet this requirement, resulting in unstable screening accuracy and prone to incomplete separation of the shell and kernel or accidental screening out of the kernel. Content of the Utility Model
[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a cashew nut shell kernel screening device, which effectively solves the problem of poor screening effect.
[0004] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a cashew nut shell kernel screening device, including a frame and a drum. The frame is provided with a drum. Driving devices and guide rollers are respectively arranged at both ends of the drum. The drum is divided into three sections. An annular fixed sleeve plate is fixedly sleeved on the outer side wall of the connection end of the drum. Limiting sliding grooves arranged in a ring shape are provided on the side walls of the fixed sleeve plates on both ends of the drum. Limiting plates are arranged to slide relatively in the limiting sliding grooves. A support frame is fixed at the top end of the limiting plate. A transverse bidirectional screw is threadedly connected to the support frame. A rotating block is fixedly sleeved in the middle of the bidirectional screw.
[0005] Preferably, the fixed sleeve plate is evenly provided with matching blocks and grooves, and the blocks are clamped in the grooves.
[0006] Preferably, the limiting plate is arc-shaped.
[0007] Preferably, a vertical plate is fixed on the top wall of the frame close to the drum, and limiting rods penetrating through the support frame are fixed on both sides of the vertical plate.
[0008] Preferably, an inclined bottom plate is provided on the bottom wall of the frame, and a material guiding plate is provided on the inclined bottom plate.
[0009] Preferably, the drum is provided with sieve holes, the drum is inclined, and the aperture of the sieve holes increases sequentially from top to bottom.
[0010] Preferably, the support frame extends in the x, y, and z directions and is a three-dimensional frame structure.
[0011] Preferably, an annular sealing ring is provided on the outer side wall of the fixed sleeve plate.
[0012] Preferably, the contact surfaces of the limiting plate and the limiting chute are both smooth surfaces.
[0013] The beneficial effects of the present utility model adopting the above structure are as follows: By rotating the rotating block to drive the bidirectional screw to rotate, the bidirectional screw drives the support frames on both sides to move away from each other, releasing the clamping of the drum, facilitating the replacement of the drum. According to the need, the drum with a corresponding aperture can be replaced, and the size of the sieve holes can be flexibly adjusted to achieve the best screening effect, ensuring the screening accuracy and ensuring complete separation of the shell and kernel.

[0020] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0021] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The following further describes the present utility model in detail with reference to the drawings.
[0022] As Figures 1 - 5 shown, a cashew shell and kernel screening device proposed by the present utility model includes a frame 1 and a drum 2. The drum 2 is provided on the frame 1. Driving devices 3 and guide rollers 4 are respectively provided at both ends of the drum 2 to drive the drum 2 to rotate. The drum 2 is divided into three sections to classify and screen cashew shells and kernels. A circular fixed sleeve plate 5 is fixedly sleeved on the outer side wall of the connection end of the drum 2. Annular limiting chutes 6 are provided on the side walls of the fixed sleeve plates 5 on both ends of the drum 2. Limiting plates 7 are slidably provided relative to each other in the limiting chutes 6. The contact surfaces of the limiting plates 7 and the limiting chutes 6 are smooth surfaces to reduce frictional resistance. A support frame 8 is fixed at the top of the limiting plate 7. The support frame 8 extends in the x, y, and z directions and has a three-dimensional frame structure. A transverse bidirectional screw 9 is threadedly connected to the support frame 8. A rotating block 10 is fixedly sleeved in the middle of the bidirectional screw 9. Rotating the rotating block 10 drives the bidirectional screw 9 to rotate. The bidirectional screw 9 drives the support frames 8 on both sides to approach each other, so that the drums 2 on both sides clamp the drum 2 in the middle. Driven by the driving device 3, the drum 2 rotates. The rotation of the drum 2 drives the fixed sleeve plate 5 to rotate. At the same time, the limiting chute 6 rotates relative to the limiting plate 7. The limiting plate 7 is arc-shaped, which is convenient for removing the support frame 8 and the limiting plate 7 as a whole and facilitates disassembly.
[0023] As Figure 4 shown, the fixed sleeve plate 5 is evenly provided with mutually matching clamping blocks 14 and clamping grooves 15. The clamping blocks 14 are clamped in the clamping grooves 15 to play a limiting role and increase the stability of the connection of the drum 2.
[0024] As Figure 2 shown, a vertical plate 11 is fixed on the top wall of the frame 1 close to the drum 2. Limiting rods 12 penetrating the support frame 8 are fixed on both sides of the vertical plate 11 to limit the support frame 8.
[0025] As Figure 1 、 3As shown in FIGS. 5, an inclined bottom plate 16 is provided on the bottom wall of the frame 1, and a material guiding plate 17 is provided on the inclined bottom plate 16, which is convenient for separately collecting cashew kernels. A sieve hole 18 is provided on the roller 2, and the roller 2 is inclined. The aperture of the sieve hole 18 increases sequentially from top to bottom. An annular sealing ring 13 is provided on the outer side wall of the fixed sleeve plate 5 to increase the sealing performance.
[0026] During specific use, when it is necessary to replace the roller 2 with different apertures, rotate the rotating block 10 to drive the bidirectional screw 9 to rotate. The bidirectional screw 9 drives the support frames 8 on both sides to move away from each other, moves the limiting plate 7 out of the limiting chute 6, releases the clamping between the rollers 2, and removes the roller 2 for replacement. When installing the roller 2, install it from bottom to top in sequence. Align the clamping block 14 with the clamping groove 15, rotate the rotating block 10 in the reverse direction, repeat the above operation, and snap the limiting plate 7 into the limiting chute 6. The rollers 2 on both sides clamp the roller 2 in the middle to complete the installation of the roller 2;
[0027] After pouring the cashew kernels from the top into the sieve of the roller 2, the driving device 3 drives the roller 2 to rotate. The rotation of the roller 2 drives the fixed sleeve plate 5 to rotate, so that the limiting chute 6 rotates relative to the limiting plate 7. Under the rotation and inclination of the roller 2, the smaller cashew kernels can fall through the sieve holes 18, while the larger cashew shells move forward along the roller 2, and finally separation is achieved.
[0028] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
