Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of shelling, and in particular relates to a shelling and grading device. Background Art
[0002] When shelling some fruits (such as hemp seeds), due to the different sizes of the fruits, if a single crushing size device is used for shelling, some small fruits may escape crushing and squeezing due to their small size, and shelling cannot be completed, which will lead to secondary rework and increase the workload of screening. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a shelling and grading device.
[0004] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:
[0005] A shelling and grading device comprises a linear vibrating screen, the linear vibrating screen being provided with a plurality of screens arranged in ascending order of mesh size, and a plurality of collecting hoppers for receiving and collecting the screened material, wherein each mesh size specification of the screen corresponds to a separate collecting hopper;
[0006] A crushing roller group is installed at the discharge port of the inner cavity of the hopper. The crushing roller group includes two crushing rollers with opposite rotation directions and used to crush the screened materials. The crushing spacing of the crushing roller group is adapted to the screening size of the corresponding screen directly above;
[0007] A depth separation box is separately arranged under each of the aggregate hoppers. The depth separation box is provided with an inlet and an outlet. The interior of the depth separation box is rotatably connected to a rotating rod. A plurality of branch rods are arranged on the circumference of the rotating rod. A plurality of spheres are arranged along the axial direction of the branch rods.
[0008] The rotating rods between the separation boxes at different depths are detachably connected and receive the rotating power provided by the power source.
[0009] It is further defined that the aggregation hopper is provided with an outer hopper and an inner hopper which are larger at the top and smaller at the bottom. The inner hopper is located in the inner cavity of the outer hopper. The entire annular upper edge of the inner hopper is connected to the inner wall of the outer hopper. The outlet of the inner hopper points to the crushing space between the two crushing rollers. Such a structural design is provided to accurately guide the material entering the aggregation hopper between the two crushing rollers to achieve crushing. The inner hopper directs the material to the crushing space for a second time to prevent the material from escaping from the side of the crushing roller and being unable to be crushed.
[0010] It is further defined that it also includes a protective net, the lower end of the protective net is connected to the outer ring of the inlet of the deep separation box, and the upper end of the protective net is connected to the outer ring of the discharge port of the aggregation hopper. With such a structural design, the protective net is mainly used to close the space between the deep separation box and the aggregation hopper to prevent materials from escaping from this space.
[0011] It is further defined that the depth separation box is also provided with mounting holes distributed on the left and right, bearings are arranged in the mounting holes, and the rotating rod cooperates with the bearings. With such a structural design, the bearings in the mounting holes support the rotating rod and reduce the friction that needs to be overcome for rotation.
[0012] It is further defined that it also includes a material receiving box, which is arranged below the outlet of the deep separation box. With such a structural design, the material receiving box is used to receive the materials dropped from the outlet.
[0013] It is further defined that the rotating rods and the rotating rods and the power source are connected via couplings. With such a structural design, the couplings achieve a detachable connection.
[0014] It is further defined that the power source is a reduction motor. With such a structural design, the reduction motor can ensure that the speed is within an appropriate range, avoiding the situation where the speed is too fast and the balls on the branches completely destroy the materials.
[0015] The beneficial effects of the present invention are as follows: the grading and screening can prevent the fruit from escaping the shelling process due to its small size, and the utility model can effectively realize the separation process of the shell through the extrusion crushing of the crushing roller group and the impact separation of the ball.

[0034] The technical solutions of the present invention are described in detail below in conjunction with specific embodiments and their accompanying drawings. The embodiments described herein are specific embodiments of the present invention and are used to illustrate the concept of the present invention; these descriptions are explanatory and exemplary and should not be understood as limiting the embodiments of the present invention and the scope of protection of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the contents disclosed in the claims of this application and its specification, including technical solutions that adopt any obvious replacements and modifications to the embodiments described herein.
[0035] Example
[0036] like Figure 1-6 As shown, this embodiment provides a shelling and grading device, including a linear vibrating screen 1, which is provided with a plurality of screens arranged in order from small to large mesh sizes, and also includes a plurality of collecting hoppers 2 for receiving and collecting the screened material, and each mesh size specification of the screen corresponds to a separate collecting hopper 2;
[0037] A crushing roller group 3 is installed at the discharge port of the inner cavity of the aggregate hopper 2. The crushing roller group 3 includes two crushing rollers with opposite rotation directions and is used to crush the screened materials. The crushing spacing of the crushing roller group 3 is adapted to the screening size of the corresponding screen directly above;
[0038] A depth separation box 4 is separately arranged under each aggregate hopper 2. The depth separation box 4 has an inlet 41 and an outlet 42. The interior of the depth separation box 4 is rotatably connected to a rotating rod 6. A plurality of branch rods 91 are arranged around the circumference of the rotating rod 6. The branch rods 91 are provided with a plurality of balls 92 along the axial direction.
[0039] The rotating rods 6 between the separation boxes 4 at different depths are detachably connected and receive the rotational power provided by the power source 7 .
[0040] In this embodiment, the fruit is poured onto the linear vibrating screen 1. Under the action of the exciting force, the fruit jumps forward and passes through the screens arranged in order from small to large meshes. When the diameter of the fruit is smaller than the aperture of the screen, it falls through the screen. If the diameter of the fruit is larger than the aperture of the screen, it continues to move forward and passes through the next screen with a larger mesh. Under the action of screens of different mesh sizes, the fruits of different sizes can be graded and screened.
[0041] Fruits of the same size are screened by the same screen and fall into the gathering hopper 2. The gathering hopper 2 gathers the fruits to the crushing roller group 3. The fruits pass between the crushing rollers and are squeezed to complete the shell crushing. The crushing spacing of the crushing roller group 3 in each gathering hopper 2 is adapted to the screening size of the corresponding screen directly above, thereby avoiding the mismatch between the fruit size and the crushing spacing, which may cause the fruit to escape.
[0042] After being squeezed by the crushing rollers, the fruit falls into the separation box 4. Driven by the power source 7, the rotating rod 6 rotates, and the branch rod 91 and the ball 92 move along with the rotating rod 6. In the process of orbiting about the axis of the rotating rod 6, the ball 92 collides with the fruit and hits the shell, thereby separating the shell from the kernel and achieving deep shelling;
[0043] In summary, the utility model can avoid the situation where fruits escape the shelling process due to their small size through graded screening, and the utility model can effectively realize the separation process of the fruit shell through the extrusion crushing of the crushing roller group and the impact separation of the ball.
[0044] Preferably, the aggregate hopper 2 comprises an outer hopper 21, which is larger at the top and smaller at the bottom, and an inner hopper 22. The inner hopper 22 is located within the inner cavity of the outer hopper 21, with the entire annular upper edge of the inner hopper 22 connected to the inner wall of the outer hopper 21. The outlet of the inner hopper 22 points toward the crushing space between the two crushing rollers. This structural design ensures that the material entering the aggregate hopper 2 is accurately directed between the two crushing rollers for crushing. The inner hopper 22 directs the material into the crushing space for a second time, preventing it from escaping from the sides of the crushing rollers and becoming unbroken. In fact, other structural shapes that ensure accurate material entry into the crushing space may also be considered depending on the specific situation.
[0045] Preferably, a protective net 11 is further included, with the lower end of the protective net 11 connected to the outer ring of the inlet 41 of the deep separation box 4, and the upper end of the protective net 11 connected to the outer ring of the discharge port of the collection hopper 2. With this structural design, the protective net 11 is mainly used to seal the space between the deep separation box 4 and the collection hopper 2, preventing material from escaping through this space. In fact, other structural shapes that prevent material escape can also be considered according to specific circumstances.
[0046] Preferably, the depth separation box 4 further has mounting holes 43 distributed on the left and right sides, with bearings 5 disposed in the mounting holes 43 and the rotating rod 6 cooperating with the bearings 5. With this structural design, the bearings 5 in the mounting holes 43 support the rotating rod 6 and reduce the friction that needs to be overcome during rotation. In fact, other structural shapes for supporting the rotating rod 6 can also be considered according to specific circumstances.
[0047] Preferably, a material receiving box 10 is further included, which is arranged below the outlet 42 of the deep separation box 4. With such a structural design, the material receiving box 10 is used to receive the materials dropped from the outlet 42. In fact, other material receiving structures can also be considered according to specific circumstances.
[0048] Preferably, the rotating rods 6 and the rotating rod 6 and the power source 7 are connected by a coupling 8. With this structural design, the coupling 8 realizes a detachable connection. In fact, other detachable connection structures can also be considered according to specific circumstances.
[0049] Preferably, the power source 7 is a reduction motor. With this structural design, the reduction motor can ensure that the speed is within a suitable range, avoiding the situation where the speed is too fast and the balls 92 on the branches 91 completely destroy the material. In fact, other types of power sources 7 can also be considered according to specific circumstances.
[0050] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be covered by the claims of the present invention.
