Description

Technical Field

[0001] This utility model relates to the field of chestnut shell and kernel separation technology, specifically, to a device for separating chestnut shells and kernels. Background Technology

[0002] Improving the efficiency of separating chestnut shells and kernels is an urgent problem to be solved in chestnut shelling and kernel separation equipment, namely chestnut shelling machines or chestnut peeling machines.

[0003] A search revealed that CN208724841U discloses a chestnut shelling machine, comprising a conical hopper with a first, second, and third roller arranged in parallel within it. The first roller is driven by a motor, the second roller by the first roller, and the third roller by the second roller. Each of the first, second, and third rollers is equipped with a striking cone. A discharge port is located below the hopper, and a sieve plate with perforations is positioned below the discharge port. A shell box and a kernel box are located below the sieve plate. This chestnut shelling machine has a simple structure, low manufacturing cost, and features three sets of rollers, resulting in a high shelling rate and good kernel integrity. It solves the problems of heavy labor intensity and low production efficiency associated with traditional manual shelling.

[0004] The aforementioned chestnut shelling machine feeds chestnuts to be shelled into the hopper and completes the shelling process using multiple sets of meshing impact cones.

[0005] The design flaw is that chestnuts poured into the cone tend to accumulate locally, leading to uneven feeding or even blockage. Additionally, when chestnuts are poured into the cone, the shells are easily squeezed and splashed out of the hopper, making cleaning difficult and potentially causing injury to workers. Utility Model Content

[0006] This invention proposes a chestnut shell and kernel separation device, which solves the problem in the prior art that chestnuts tend to accumulate locally when poured onto the impact cone, leading to uneven feeding or even blockage at the impact cone; at the same time, when chestnuts are poured onto the impact cone, the chestnut shells are easily squeezed by the impact cone and splash out from the hopper, which is not only troublesome to clean, but may also cause accidental injury to workers.

[0007] The technical solution of this utility model is as follows: A chestnut shell and chestnut kernel separation device includes a chestnut shell and kernel separation seat and a separation cone column symmetrically arranged in the lower part of the inner cavity of the chestnut shell and kernel separation seat. The top of the chestnut shell and kernel separation seat is symmetrically provided with anti-splash components that can prevent chestnut shells from splashing out of the chestnut shell and kernel separation seat during chestnut separation. Inside the chestnut shell and kernel separation seat, above the separation cone column, a material guiding component is provided. The material guiding component includes a slide seat and a rigid guide tube that can evenly distribute the falling chestnuts at the anti-splash component and guide them to the separation cone column for separation.

[0008] Preferably, the material guiding assembly further includes a forward and reverse motor, which is fixedly installed on the outside of the chestnut kernel separating seat. The material guiding assembly also includes a threaded rod, one end of which is fixedly connected to the forward and reverse motor. The threaded rod is rotatably connected to the transverse groove on the inner wall of the chestnut kernel separating seat through the forward and reverse motor.

[0009] Preferably, the slide is threaded to the threaded rod, and a slot is provided on one side of the slide, the slot corresponding to the position of the rigid conduit, and the rigid conduit is engaged in the slot.

[0010] Preferably, the material guiding assembly further includes two sets of material guiding ramps, which are symmetrically and fixedly connected to the inner wall of the chestnut kernel separating seat.

[0011] Preferably, the material guiding assembly further includes a confluence plate, which is fixedly connected to the two side material guiding ramps. The material guiding assembly also includes a lower through groove, which is formed through the middle of the confluence plate.

[0012] Preferably, the material guiding assembly further includes a flexible conduit, the top of which is fixedly connected to the lower through groove, and the bottom of which is fixedly connected to the rigid conduit.

[0013] Preferably, the splash-proof component includes an inner slope seat, which is fixedly connected to the inner wall of the chestnut kernel separating seat. A torsion bar is rotatably connected to the bottom side of the inner slope seat, and a feeding plate is fixedly connected to the side of the torsion bar. The two sets of feeding plates are in contact with each other.

[0014] Preferably, the splash-proof assembly further includes torsion springs, each torsion spring being sleeved on both sides of each torsion bar, one end of each torsion spring being fixedly connected to the inner slope seat, and the other end of each torsion spring being fixedly connected to the torsion bar.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This design features a feeding plate at the bottom of the inner slope seat. When the chestnut falls from the inner slope seat and contacts the feeding plate, the feeding plate will be pushed by the chestnut as it falls and flipped by the torsion bar and torsion spring. This causes the chestnut to push open the feeding plate and fall into the chestnut shell and kernel separation seat. At the same time, after the chestnut has finished feeding, the feeding plate will be horizontally reset by the elastic action of the torsion bar and torsion spring. This design can prevent the chestnut from splashing out to the outside of the chestnut shell and kernel separation seat when it is squeezed and separated at the separation cone.

[0017] 2. This design incorporates a material guiding component at the connection between the splash-proof assembly and the separation cone. When the chestnut falls from the discharge plate, it passes through the guiding ramp and the confluence plate in sequence, and then falls from the soft guide tube and the hard guide tube to the separation cone. At this point, the forward and reverse motors can be activated to drive the threaded rod to rotate alternately in both directions, thereby allowing the hard guide tube to evenly spread the fallen chestnuts at the separation cone. Compared to the prior art, this design can prevent the chestnuts from accumulating locally during the peeling process at the separation cone, thus avoiding blockage. Attached Figure Description

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1 and Figure 2 and Figure 3 This utility model provides a technical solution: a chestnut shell and chestnut kernel separation device, including a chestnut shell and kernel separation seat 1 and a separation cone column 2 symmetrically arranged in the lower part of the inner cavity of the chestnut shell and kernel separation seat 1. A splash-proof component 4 is symmetrically arranged on the top of the chestnut shell and kernel separation seat 1 to prevent chestnut shells from splashing out to the outside of the chestnut shell and kernel separation seat 1 during chestnut separation. A material guiding component 3 is arranged inside the chestnut shell and kernel separation seat 1 above the separation cone column 2. The material guiding component 3 includes a slide 32 that can evenly distribute and guide the falling chestnuts from the splash-proof component 4 to the separation cone column 2 for separation and a rigid guide tube 33.

[0026] This design solves the problem in existing technologies where chestnuts tend to accumulate locally when poured onto the cone, leading to uneven feeding or even blockage. Additionally, when chestnuts are poured onto the cone, the shells are easily squeezed and splashed out of the hopper, making cleaning difficult and potentially causing injury to workers.

[0027] Please see Figure 1 and Figure 2 The feeding assembly 3 also includes a forward and reverse motor 31, which is fixedly installed on the outside of the chestnut kernel separating seat 1. The feeding assembly 3 also includes a threaded rod 311, one end of which is fixedly connected to the forward and reverse motor 31. The threaded rod 311 is rotatably connected to the transverse groove on the inner wall of the chestnut kernel separating seat 1 through the forward and reverse motor 31.

[0028] The slide block 32 is threadedly connected to the threaded rod 311. A slot 321 is provided on one side of the slide block 32. The slot 321 corresponds to the position of the rigid guide tube 33. The rigid guide tube 33 is engaged in the slot 321.

[0029] The material guiding assembly 3 also includes two sets of material guiding ramps 35, which are symmetrically fixedly connected to the inner wall of the chestnut kernel separating seat 1.

[0030] The material guiding assembly 3 also includes a confluence plate 36, which is fixedly connected to the material guiding ramps 35 on both sides. The material guiding assembly 3 also includes a lower through groove 361, which is opened through the middle of the confluence plate 36.

[0031] The material guiding assembly 3 also includes a soft guide tube 34, the top of which is fixedly connected to the lower through groove 361, and the bottom of which is fixedly connected to the hard guide tube 33;

[0032] This design allows chestnuts to slide off the hard conduit 33 and spread evenly on the separating cone 2 to complete the peeling process.

[0033] Please see Figure 3 and Figure 4The splash-proof component 4 includes an inner slope seat 41, which is fixedly connected to the inner wall of the chestnut kernel separating seat 1. A torsion bar 42 is rotatably connected to the bottom side of the inner slope seat 41, and a feeding plate 43 is fixedly connected to the side of the torsion bar 42. The two sets of feeding plates 43 are in contact with each other.

[0034] The splash-proof assembly 4 also includes torsion springs 421. Each torsion spring 421 is respectively sleeved on both sides of each torsion bar 42. One end of each torsion spring 421 is fixedly connected to the inner slope seat 41, and the other end of each torsion spring 421 is fixedly connected to the torsion bar 42.

[0035] This design prevents the chestnut shell from being squeezed outwards by the separating cone 2 and splashing outwards from the chestnut kernel separating seat 1 when the chestnut is peeled at the separating cone 2.

[0036] The working principle and usage process of this utility model are as follows:

[0037] First, the staff selects an appropriate amount of chestnuts and pours them from the top of the chestnut shell and kernel separating seat 1 at the inner slope seat 41. When the chestnuts fall from the inner slope seat 41 to contact the feeding plate 43, the feeding plate 43 will be pushed by the chestnuts as they fall and flipped in the cooperation of the torsion bar 42 and the torsion spring 421, so that the chestnuts push open the feeding plate 43 and fall into the chestnut shell and kernel separating seat 1. At the same time, after the chestnuts have finished feeding, the feeding plate 43 will be horizontally reset under the elastic action of the torsion bar 42 and the torsion spring 421.

[0038] This design prevents chestnuts from splashing out to the outside of the chestnut kernel separating seat 1 when they are squeezed and separated at the separating cone 2.

[0039] When the chestnuts fall from the feeding plate 43, they will pass through the guide ramp 35 and the confluence plate 36 in sequence, and fall from the soft guide tube 34 and the hard guide tube 33 to the separation cone 2. At this time, the forward and reverse motor 31 can be started to drive the threaded rod 311 to rotate in both directions, so that the hard guide tube 33 will evenly spread the fallen chestnuts on the separation cone 2.

[0040] This step prevents chestnuts from accumulating locally and causing blockages during the peeling process of the separation cone 2.

[0041] This design solves the problem of oil buildup and blockage at the connection between the discharge pipe 1 and the oil outlet hose 2, which is difficult to clean.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
